[0158] Example 1

[0159] Figure 1 illustrates a structural schematic diagram of a display screen provided in an embodiment of the present disclosure, Figure 2 illustrates a side view of a display screen provided in an embodiment of the present disclosure, and Figure 3 illustrates a structural schematic diagram of a mounting bracket 10 provided in an embodiment of the present disclosure. As shown in Figures 1, 2, and 3, the mounting bracket 10 includes: a fixing frame 11 and a hanging bracket 12. The fixing frame 11 includes a first fixing part 111, a bearing part 112, and a first limiting part 113. The first fixing part 111 has a first contact surface 1112, which is used to contact the mounting surface 31 of the carrier 30, and the first fixing part 111 is used to connect to the mounting surface 31 of the carrier 30. The bearing part 112 is connected to the side of the first fixing part 111 away from the first contact surface 1112 and has a bearing surface 1121. The first limiting part 113 is connected to the bearing surface 1121. The hanging bracket 12 includes a second fixing part 121, a connecting part 122, and a first mating part 123. 21 has a second bonding surface 1211, which is used to bond to the back of the splicing screen 20, and a second fixing part 121 is used to connect to the back of the splicing screen 20. A connecting part 122 is connected to the side of the second fixing part 121 away from the second bonding surface 1211. A first mating part 123 is connected to the connecting part 122. The first mating part 123 is used to cooperate with the first limiting part 113. When the splicing screen 20 is in the installed state, the first mating part 123 is limited in the first hanging groove 114. The first hanging groove 114 is surrounded by the first limiting part 113, the bearing surface 1121 and the first fixing part 111, or it is surrounded by the first limiting part 113, the bearing surface 1121 and the mounting surface 31.

[0160] In this embodiment, the mounting bracket 10 includes a fixing bracket 11 and a hanging bracket 12, which fixes the splicing screen 20 on the mounting surface 31 of the carrier 30, thereby simplifying the installation of the splicing screen 20 and improving installation efficiency. When the splicing screen 20 is in the installed state, the first mating part 123 of the hanging bracket 12 is limited within the first hanging groove 114 formed by the first limiting part 113, the bearing surface 1121, and the first fixing part 111 or the mounting surface 31. At this time, based on the locking of multiple splicing screens 20, the first mating part 123 can move within the first hanging groove 114, thereby realizing the adaptive adjustment of the splicing screen 20 in the direction of the vertical mounting surface 31, so as to reduce or even avoid the force of the splicing screen 20 in the direction of the vertical mounting surface 31, and facilitate the extension of service life.

[0161] In some embodiments, as shown in FIG3, the first fixing part 111 is used to connect to the mounting surface 31 which forms a first angle θ1 with the horizontal plane; when the splicing screen 20 is in the installed state, the bearing surface 1121 is the surface of the bearing part 112 facing away from the ground, so that the first limiting part 113 is located on the side of the bearing part 112 facing away from the ground; when the splicing screen 20 is in the installed state, the first mating part 123 is connected to the surface of the connecting part 122 facing the ground.

[0162] Optionally, the mounting surface 31 connecting the first fixing part 111 forms a first angle θ1 with the horizontal plane that is greater than or equal to 80 degrees and less than or equal to 100 degrees. For example, the first angle θ1 between the mounting surface 31 and the horizontal plane is 80 degrees, 82 degrees, 84 degrees, 86 degrees, 88 degrees, 90 degrees, 92 degrees, 94 degrees, 96 degrees, 98 degrees, 100 degrees, etc.; preferably, the first angle θ1 between the mounting surface 31 and the horizontal plane is 90 degrees.

[0163] In addition, the mounting surface 31 is not a plane in the strict sense, but has certain protrusions and / or depressions. After multiple splicing screens 20 are locked together, the hanger 12 can move in the first mounting groove 114 in the direction perpendicular to the mounting surface 31 to ensure the flatness of multiple splicing screens 20, and at the same time avoid stress between two splicing screens 20 that are locked together, thereby extending the service life of the splicing screens 20.

[0164] Specifically, when the splicing screen 20 is hung in the first mounting slot 114 of the fixed frame 11 based on the bracket 12, it can be as shown in Figure 3, where the recess of the mounting surface 31 causes the first mating part 123 to move to a position that contacts the first limiting part 113, or it can be as shown in Figure 4a, where the protrusion of the mounting surface 31 causes a certain gap between the first mating part 123 and the first limiting part 113.

[0165] In some embodiments, the width of the first mounting groove 114 in the direction perpendicular to the mounting surface 31 is greater than or equal to 5 mm and less than or equal to 15 mm. This ensures that the first mating part 123 has sufficient room to move within the first mounting groove 114, thereby avoiding stress between the first mating part 123 and the first limiting part 113 due to the recess of the mounting surface 31, and avoiding stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the protrusion of the mounting surface 31.

[0166] For example, the width of the first mounting groove 114 in the direction perpendicular to the mating surface of the first fixing part 111 is 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, etc.

[0167] Of course, the width of the first mounting groove 114 in the direction perpendicular to the mating surface of the first fixing part 111 can also be other values, as long as the movable distance of the first mating part 123 in the first mounting groove 114 along the direction perpendicular to the mounting surface 31 (i.e., the first mating surface 1112) is greater than or equal to the flatness of the mounting surface 31, so as to avoid stress between the first mating part 123 and the first limiting part 113 due to the concavity of the mounting surface 31, and to avoid stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the convexity of the mounting surface 31; or the movable distance of the first mating part 123 limited in the first mounting groove 114 is slightly less than the flatness of the mounting surface 31, so as to avoid large stress between the first mating part 123 and the first limiting part 113 due to the concavity of the mounting surface 31, and to avoid large stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the convexity of the mounting surface 31.

[0168] In some embodiments, as shown in FIG5, the first limiting part 113 has a first surface 1132 located near the first mating part 123. The first surface 1132 forms a second angle θ2 with the exposed surface of the bearing surface 1121, and the second angle θ2 is an obtuse angle. The first mating part 123 has a second surface 1232 located near the first limiting part 113. The second surface 1232 forms a third angle θ3 with the exposed surface of the connecting part 122 facing the first limiting part 113, and the third angle θ3 is an obtuse angle. Here, the exposed surface refers to the surface that can contact the outside world. In FIG5, the exposed surface of the bearing surface 1121 is the solid outer contour area, which is not the contact area between the inside of the first limiting part 113 and the bearing surface 1121 (such as not the dashed area of ​​the bearing part 112 in FIG4a). As shown in Figure 5, the exposed surface of the connecting part 122 facing the first limiting part 113 is the solid outer contour area, which is not the contact area between the connecting part 122 and the first mating part 123 (such as not the dashed area of ​​the connecting part 122 in Figure 4a).

[0169] Thus, by setting the first surface 1132 and the second surface 1232 to be inclined, it is convenient to guide the first limiting part 113 to the first mating part 123, thereby facilitating the hanging of the bracket 12 in the first hanging groove 114 and improving the installation efficiency of the splicing screen 20; in addition, when the first surface 1132 and the second surface 1232 are in contact, the first limiting part 113 can support the first mating part 123, thereby further improving the stability of the bracket 12 hanging on the fixed frame 11.

[0170] Optionally, the second included angle θ2 and the third included angle θ3 are of equal degree so that when the first surface 1132 contacts the second surface 1232, it is a surface contact, thereby increasing the support area of ​​the first limiting part 113 on the first mating part 123.

[0171] For example, the second included angle θ2 and the third included angle θ3 are greater than or equal to 100 degrees and less than or equal to 170 degrees, such as the second included angle θ2 and the third included angle θ3 being 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, etc.

[0172] Specifically, the first surface 1132 of the first limiting part 113 near the first mating part 123 and the bearing surface 1121 of the bearing part 112, as well as the second surface 1132 of the first mating part 123 near the first limiting part 113 and the side surface of the connecting part 122 facing the first limiting part 113, can be set as an arc transition to avoid stress concentration between the first limiting part 113 and the bearing part 112, and between the first mating part 123 and the connecting part 122. Of course, reinforcing ribs can also be provided between the side surface of the first limiting part 113 facing away from the first fixing part 111 and the bearing part 112, and between the side surface of the first mating part 123 facing away from the second fixing part 121 and the connecting part 122, to strengthen the connection strength between the first limiting part 113 and the bearing part 112, and between the first mating part 123 and the connecting part 122, while providing support for the first limiting part 113 and the first mating part 123, thereby preventing breakage between the first limiting part 113 and the bearing part 112, and between the first mating part 123 and the connecting part 122.

[0173] In some embodiments, as shown in FIG5, the first limiting portion 113 further has a third surface 1133 disposed opposite to the first surface 1132, and the first surface 1132 and the third surface 1133 are parallel to each other; the first mating portion 123 further has a fourth surface 1234 disposed opposite to the second surface 1232, and the fourth surface 1234 is parallel to each other, that is, the first limiting portion 113 is inclinedly disposed on the bearing portion 112, and the first mating portion 123 is inclinedly disposed on the connecting portion 122. The vertical distance from the first surface 1132 to the third surface 1133 is equal to the vertical distance from the second surface 1232 to the fourth surface 1234.

[0174] Thus, the parallelogram-like structure formed by the first limiting part 113 and the first mating part 123 in this embodiment can save materials and reduce weight while ensuring installation strength.

[0175] Optionally, as shown in FIG4a, when the splicing screen 20 is in any installed state, the orthographic projections of the first limiting part 113 and the first mating part 123 on the bearing surface 1121 are both located between the orthographic projections of the surface of the first fixing part near 111 near the bearing part 112 on the bearing surface 1121 and the orthographic projections of the surface of the second fixing part 121 near the connecting part 122 on the bearing surface 1121. That is, the first limiting part 113 is connected to the middle area of ​​the bearing part 112, and when the splicing screen 20 is in the installed state, there is a certain distance between the free end of the first limiting part 113 and the back of the splicing screen 20; the first mating part 123 is connected to the middle area of ​​the connecting part 122, and when the splicing screen 20 is in the installed state, there is a certain distance between the free end of the first mating part 123 and the mounting surface 31.

[0176] Optionally, as shown in FIG4b, the dimension R1 of a cross section of the first limiting part 113 on a plane parallel to the first direction X and the second direction Y is larger as it gets closer to the bearing part 112, so as to enhance the connection strength between the first limiting part 113 and the bearing part 112.

[0177] Optionally, as shown in FIG4b, the dimension R2 of a cross section of the first mating part 123 on a plane parallel to the first direction X and the second direction Y is larger as it gets closer to the connecting part 122, so as to enhance the connection strength between the first mating part 123 and the connecting part 122.

[0178] In some embodiments, as shown in FIG3, FIG4a or FIG6, the free end of the first limiting part 113 has a first bent part 1131 facing away from the first fixing part 111, and the free end of the first mating part 123 has a second bent part 1231 facing away from the second fixing part 121. The distance from the first bent part 1131 to the bearing part 112 is equal to the distance from the second bent part 1231 to the connecting part 122.

[0179] Thus, by setting the first bending part 1131 and the second bending part 1231, and by ensuring that the distance from the first bending part 1131 to the bearing part 112 is equal to the distance from the second bending part 1231 to the connecting part 122, it is ensured that when the free end of the first mating part 123 contacts the bearing surface 1121 of the bearing part 112, the first bending part 1131 abuts against the connecting part 122, and at the same time, the second bending part 1231 abuts against the bearing surface 1121. This increases the support area of ​​the bracket 12 on the fixed frame 11, thereby facilitating the improvement of the stability of the fixed frame 11 in supporting the bracket 12, that is, ensuring the stability of the splicing screen 20 installed on the mounting surface 31 of the carrier 30.

[0180] In this design, the first bent portion 1131 faces away from the first fixed portion 111, meaning the distance between the edge of the first bent portion 1131 away from the first limiting portion 113 and the first fixed portion 111 is greater than the distance between the free end of the first limiting portion 113 and the first fixed portion 111. Similarly, the second bent portion 1231 faces away from the second fixed portion 121, meaning the distance between the edge of the second bent portion 1231 away from the first mating portion 123 and the second fixed portion 121 is greater than the distance between the free end of the first mating portion 123 and the second fixed portion 121. Furthermore, the arrangement of the second bent portion 1231 inevitably reduces the movable space of the first mating portion 123 within the first mounting groove 114 in the direction perpendicular to the first contact surface 1112. Therefore, when designing the mounting bracket 11, the first mounting groove 114 can be wider in the direction perpendicular to the first contact surface 1112 to ensure the self-adjustment of the bracket 12 within the first mounting groove 114 after the splicing screen 20 is installed.

[0181] In some embodiments, as shown in Figures 7 and 8, the mounting bracket 10 further includes a bolt 13; the connecting part 122 has a threaded hole (not shown in the figure), the threaded hole is located on the side of the first mating part 123 away from the second fixing part 121, and when the splicing screen 20 is in the installed state, one end of the bolt 13 is screwed into the threaded hole and abuts against the bearing surface 1121.

[0182] The threaded hole is located on the side of the first mating part 123 away from the second fixing part 121, that is, the distance from the threaded hole to the second fixing part 121 is greater than the distance from the free end of the first mating part 123 to the second fixing part. The bolt 13 is threaded in the threaded hole of the connecting part 122. As shown in Figures 8 and 9, after the end of the bolt 13 abuts against the bearing surface 1121 of the bearing part 112, the bolt 13 can be tightened. Thus, when the connecting part 122 cannot rotate synchronously, the distance between the connecting part 122 and the bearing surface 1121 in the length direction of the bolt 13 can be adjusted to realize the height adjustment of the bracket 12, so as to effectively ensure the locking and fixing between multiple splicing screens 20.

[0183] The nut end of the bolt 13 can be a polygonal structure, so that the bolt 13 can be tightened or loosened by a wrench, or the nut end can have a limiting groove (such as a cross or slotted structure), so that the bolt 13 can be tightened or loosened by a corresponding screwdriver.

[0184] As shown in Figure 9, after adjusting the position of the bracket 12 in the height direction by continuing to tighten the bolt 13, there is no contact between the first limiting part 113 and the connecting part 122, and between the first mating part 123 and the bearing part 112. At this time, the bracket 12 is supported on the fixed frame 11 only by the end of the bolt 13 abutting against the bearing surface 1121.

[0185] When adjusting the height of the splicing screen 20 using bolts 13, one splicing screen 20 can correspond to multiple bolts 13, so that the parallelism of the upper surface of the splicing screen 20 can be ensured when adjusting the height of the splicing screen 20 using multiple bolts 13 that are spaced apart.

[0186] In conjunction with the above description, the free end of the first mating part 123 has a second bent part 1231. As shown in Figures 10 and 11, the second bent part 1231 has a relief groove 1233 (away from the edge of the first mating part 123), so that the bolt 13 can pass through the relief groove 1233 and abut against the bearing surface 1121 of the bearing part 112 to avoid interference between the second bent part 1231 and the bolt 13.

[0187] In some embodiments, as shown in Figures 10 and 11, the support portion 112 has a groove 1122 located on the support surface 1121; the groove 1122 is located on the side of the first limiting portion 113 near the first fixing portion 111, and the length direction of the groove 1122 is parallel to the plane perpendicular to the first mating surface 1112. When the splicing screen 20 is in the installed state, one end of the bolt 13 that abuts against the support surface 1121 is limited in the groove 1122.

[0188] Thus, by providing a groove 1122 on the bearing surface 1121 of the bearing part 112, and limiting one end of the bolt 13 within the groove 1122, the movement of the bolt 13 along the direction close to or away from the first limiting part 113 is ensured, while limiting the movement of the bolt 13 along the width direction of the groove 1122. This ensures the adaptive adjustment of the splicing screen 20 in the direction perpendicular to the contact surface of the first fixing part 111, while preventing the splicing screen 20 from moving in the horizontal direction parallel to the contact surface of the first fixing part 111, thereby ensuring the stability of the splicing screen 20 installed on the mounting bracket 10.

[0189] When the bearing surface 1121 on the bearing part 112 is perpendicular to the first mating surface 1112, the length direction of the slide groove 1122 is perpendicular to the first mating surface 1112. One end of the slide groove 1122 extends to the edge of the bearing surface 1121 near the first fixing part 111, and the other end extends to the corner where the first limiting part 113 connects to the bearing surface 1121, so as to ensure the sliding space of the bolt 13 in the slide groove 1122, thereby ensuring the adaptive adjustment of the splicing screen 20 in the first hanging groove 114.

[0190] Of course, the length of the slide groove 1122 can also be set slightly shorter. For example, since the threaded hole on the connecting part 122 is not located at the edge of the connecting part 122, one end of the slide groove 1122 does not need to extend to the edge of the bearing surface 1121 near the first fixing part 111. And since the first mating part 123 occupies space in the first hanging groove 114, the other end of the slide groove 1122 does not need to extend to the corner where the first limiting part 113 connects to the bearing surface 1121. In this way, the self-adaptive adjustment of the splicing screen 20 in the first hanging groove 114 is ensured, while also facilitating the structural strength of the bearing part 112.

[0191] Furthermore, in the case where one video wall 20 corresponds to multiple bolts 13, as described above, the bearing surface 1121 of the bearing portion 112 may have only one groove 1122 for limiting one bolt 13, or the bearing surface 1121 may have grooves 1122 for limiting each bolt 13 respectively. For example, one video wall 20 corresponds to two bolts 13, and the bearing surface 1121 of the bearing portion 112 has only one groove 1122 for limiting one bolt 13.

[0192] In some embodiments, as shown in FIG3, the mounting surface 31 connecting the first fixing part 111 forms a first angle θ1 with the horizontal plane, and the extension surface of the first mating surface 1112 (i.e., the mounting surface 31) forms a fourth angle θ4 with the bearing surface 1121, wherein the first angle θ1 and the fourth angle θ4 are equal in degree.

[0193] This ensures that after the first contact surface 1112 of the first fixing part 111 is in contact with the mounting surface 31 of the carrier 30, the bearing surface 1121 of the bearing part 112 is always parallel to the horizontal plane. This facilitates the stable support of the bracket 12 by the bearing surface 1121, and at the same time ensures the stable suspension of the splicing screen 20 on the fixing frame 11. It also prevents the bracket 12 from moving in the direction perpendicular to the first contact surface 1112 when it is attached to the fixing frame 11, and thus prevents the splicing screen 20 from moving in the direction perpendicular to the first contact surface 1112. This further avoids the interaction force between adjacent splicing screens 20.

[0194] In some embodiments, the angle between the extension surface of the second bonding surface 1211 (i.e., the back side of the splicing screen 20) and the surface of the connecting portion 122 facing the first limiting portion 113 is 90 degrees; and / or, the angle between the extension surface of the first bonding surface 1112 (i.e., the mounting surface 31) and the bearing surface is 90 degrees.

[0195] The first angle θ1 between the mounting surface 31 of the carrier 30 and the horizontal plane is 90 degrees, that is, the mounting surface 31 of the carrier 30 is a vertical surface. In this way, after the splicing screen 20 is hung on the fixed frame 11 by the bracket 12, it is easy to ensure that the display surface of the splicing screen 20 is a vertical surface, thereby ensuring the display effect of the splicing screen 20 after installation.

[0196] In some embodiments, as shown in FIG12, the hanger 12 further includes a first reinforcing part 124 integrally formed with the second fixing part 121; the first reinforcing part 124 is disposed opposite to the connecting part 122 and is located on the side of the connecting part 122 away from the first mating part 123.

[0197] The two sides of the second fixing part 121 are connected to the connecting part 122 and the first reinforcing part 124 respectively (e.g., integrally formed), forming a U-shaped structure with the connection end face. In this way, the structure of the bracket 12 is equivalent to the structure of the channel steel, thereby effectively ensuring the structural strength of the bracket 12 and thus ensuring the stability of the splicing screen 20 installed on the mounting bracket 10.

[0198] In some implementations, as shown in FIG13, the bracket 12 is a strip structure, and one bracket 12 is used to be fixedly connected to one splicing screen 20, that is, one splicing screen 20 corresponds to one bracket 12.

[0199] The strip-shaped bracket 12 has a certain length, which is equal to or slightly less than the width of a video wall 20, so that one bracket 12 can be used to install one video wall 20. In addition, the strip-shaped bracket 12 facilitates leveling when the second fixing part 121 of the bracket 12 is fixedly connected to the back of the video wall 20. That is, it is easy to ensure that the length direction of the bracket 12 is parallel to the upper surface of the video wall 20, and at the same time, it simplifies the fixed installation of the bracket 12 on the back of the video wall 20.

[0200] In some other embodiments, as shown in FIG14, the bracket 12 is a block structure, and multiple brackets 12 are used to be fixedly connected to the same splicing screen 20, that is, one splicing screen 20 corresponds to multiple brackets 12.

[0201] Among them, the bracket 12 is a block structure, that is, the length of the bracket 12 is relatively short, and multiple brackets 12 are required to install a splicing screen 20. In addition, the bracket 12 is set as a block structure, which helps to save materials for the bracket 12, thereby saving costs. At the same time, it is easy to make the bracket 12 lightweight, so as to reduce the weight borne by the fixing frame 11 and ensure the stability of the fixing frame 11 and the mounting surface 31 of the carrier 30.

[0202] Optionally, as shown in Figure 14, the bracket 12 also includes a pin 125 fixed to the side of the second fixing part 121 away from the connecting part 122; when the splicing screen 20 is in the installed state, the pin 125 passes through the limiting hole on the housing of the splicing screen 20 to position the bracket, thereby preventing the block-shaped bracket 12 from rotating.

[0203] In this embodiment of the disclosure, the specific structure of the hanger 12 may be that the second fixing part 121, the connecting part 122 and the first mating part 123 are integrally formed. The specific structure of the fixing frame 11 may be that the first fixing part 111, the bearing part 112 and the first limiting part 113 are integrally formed, or the bearing part 112 and the first limiting part 113 are integrally formed and are limitedly connected to the first fixing part 111.

[0204] In some embodiments, as shown in FIG15 or FIG16, the fixing frame 11 is a strip structure, and the first fixing part 111, the bearing part 112 and the first limiting part 113 are an integral structure.

[0205] The strip-shaped mounting bracket 11 has a certain length, which is greater than or equal to the sum of the widths of multiple splicing screens 20 (e.g., the sum of the widths of 2, 3, 5, or 8 splicing screens 20). This ensures that multiple splicing screens 20 can be installed using a single mounting bracket 11, thus facilitating the fixing of multiple splicing screens 20 at the same height. Alternatively, if the length of a single mounting bracket 11 is short, adjacent mounting brackets 11 can be connected via an interlocking interface to ensure that multiple mounting brackets 11 for a corresponding row of splicing screens 20 are at the same height, i.e., multiple mounting brackets 11 are aligned on the same straight line.

[0206] The first fixing part 111, the bearing part 112 and the first limiting part 113 are integrated into one structure, which facilitates the strengthening of the structural strength of the fixing frame 11. At the same time, the fixing frame 11 is a strip structure, so that the hanging frame 12 can be hung at any position of the fixing frame 11, thus facilitating the hanging of the splicing screen 20 at any position of the fixing frame 11.

[0207] The supporting part 112 is connected to the side of the first fixing part 111 away from the mating surface. The connection between the surface of the supporting part 112 away from the bearing surface 1121 and the first fixing part 111 is an arc transition, thereby avoiding stress concentration at the connection between the supporting part 112 and the first fixing part 111. Alternatively, a reinforcing rib can be provided on the side of the supporting part 112 away from the bearing surface 1121 to connect the supporting part 112 and the first fixing part 111, so as to ensure the connection strength between the supporting part 112 and the first fixing part 111, thereby ensuring the support strength of the supporting part 112 for the bracket 12 on which the splicing screen 20 is fixed.

[0208] In some embodiments, as shown in FIG15, the first fixing part 111 has a plurality of strip-shaped holes 1111 spaced apart along the length direction, and the length direction of each strip-shaped hole 1111 is parallel to the arrangement direction of the plurality of strip-shaped holes 1111.

[0209] Among them, the strip-shaped hole 1111 is a through hole with a certain length, such as an oblong hole or a rectangular hole. By setting multiple strip-shaped holes 1111, it is convenient to adjust the position of each fixing bolt in the corresponding strip-shaped hole 1111 when the first fixing part 111 is fixed to the mounting surface 31 of the carrier 30, thereby ensuring the stability of the fixing frame 11 and the mounting surface 31 of the carrier 30.

[0210] In some other embodiments, as shown in FIG16, the first fixing part 111 has multiple sets of strip holes 1111 spaced apart along the width direction (two sets of strip holes 1111 are shown in FIG16); each set of strip holes 1111 includes multiple strip holes 1111 spaced apart along the length direction of the first fixing part 111, and the length direction of each strip hole 1111 is parallel to the arrangement direction of the multiple strip holes 1111; the gaps between the multiple sets of strip holes 1111 in the length direction of the first fixing part 111 do not overlap in the width direction of the first fixing part 111.

[0211] Optionally, as shown in FIG16, the multiple sets of strip-shaped holes 1111 include a first set of strip-shaped holes (denoted as first strip-shaped hole 1111a) and a second set of strip-shaped holes (denoted as second strip-shaped hole 1111b). The first strip-shaped holes 1111a and the second strip-shaped holes 1111b have the same size, and the first strip-shaped holes 1111a and the second strip-shaped holes 1111b are staggered in the length direction (i.e., the third direction Z) of the first fixing part 111. The first strip-shaped hole 1111a is closer to the bearing part 112 than the second strip-shaped hole 1111b; the ratio of the hole gap L3 between the first strip-shaped hole 1111a and the adjacent first strip-shaped hole 1111a is between 2 and 8; the ratio of the hole gap L3 between the second strip-shaped hole 1111b and the adjacent first strip-shaped hole 1111a is between 0.9 and 1.2. Optionally, the ratio of the gap L3 between the first strip hole 1111a and the adjacent first strip hole 1111a is between 2 and 3; the ratio of the gap L3 between the second strip hole 1111b and the adjacent first strip hole 1111a is between 0.9 and 1, that is, the size of the second strip hole 1111b is less than or equal to the gap L3, so as to ensure that the missing area is filled while ensuring the structural strength.

[0212] By providing multiple sets of strip-shaped holes 1111 on the first fixing part 111, and ensuring that the gaps between the multiple sets of strip-shaped holes 1111 in the length direction of the first fixing part 111 do not overlap in the width direction of the first fixing part 111, the first fixing part 111 can be fixed at any position in the length direction. This avoids the fixing of the fixing frame 11 when there are empty areas on the carrier 30. For example, in the case where the mounting surface 31 is the surface of multiple columns, the gap between two adjacent columns constitutes an empty area of ​​the carrier 30. In this case, for the first fixing part 111 with multiple sets of strip-shaped holes 1111, the empty area can be avoided, and the fixing frame 11 can be fixed to the multiple columns by holes on the first fixing part 111 corresponding to the area where the columns are located.

[0213] In some embodiments, as shown in FIG1, the first fixing part 111 is used to connect to the surface (mounting surface 31) of the carrier 30, which is a wall.

[0214] Of course, considering the case where the first fixing part 111 has multiple sets of strip-shaped holes 1111 as described above, the first fixing part 111 can also be connected to the surface of the carrier 30, which is a column. For example, as shown in FIG17, the splicing screen 20 is mounted on the surface of multiple columns (carriers 30) via the mounting bracket 10.

[0215] In some embodiments, as shown in FIG15 or FIG16, the fixing frame 11 further includes a second reinforcing part 115 integrally formed with the first fixing part 111; the second reinforcing part 115 is disposed opposite to the bearing part 112 and is located on the side of the bearing part 112 away from the first limiting part 113.

[0216] The first fixing part 111 has two sides that are connected to the bearing part 112 and the second reinforcing part 115 respectively (e.g., integrally formed), with the connection having a U-shaped end face. In this way, the structure of the fixing frame 11 is equivalent to that of the channel steel, thereby effectively ensuring the structural strength of the fixing frame 11, and thus ensuring the stability of the splicing screen 20 when it is hung on the fixing frame 11.

[0217] In some embodiments, the first fixing part 111 and the bearing part 112 are connected in an L-shaped structure. When the fixing frame 11 is connected to the mounting surface 31 of the carrier 30, the first limiting part 113, the bearing surface 1121, and the mounting surface 31 form a first hanging groove 114.

[0218] The first fixing part 111 and the bearing part 112 are connected in an L-shaped structure at the end face. The first fixing part 111 can be fixed on the mounting surface 31 of the carrier 30 on the side of the bearing part 112 away from the first limiting part 113. At the same time, it can prevent the nuts of the fixing bolts of the first fixing part 111 from being located in the first hanging groove 114, which would affect the movable distance of the first mating part 123 in the first hanging groove 114. This ensures the adaptive adjustment function of the splicing screen 20 in the direction of the mating surface perpendicular to the first fixing part 111.

[0219] In other embodiments, the first fixing part 111 and the bearing part 112 are connected in a T-shaped structure, and the first limiting part 113, the bearing surface 1121, and the first fixing part 111 form a first hanging groove 114.

[0220] The first fixing part 111 and the supporting part 112 are connected in a T-shaped structure at their end faces. This allows the first fixing part 111 to be fixed to the mounting surface 31 of the carrier 30 from both sides of the supporting part 112, ensuring the tightness of the connection between the first fixing part 111 and the carrier 30. Furthermore, the fixing hole on the first fixing part 111 located on the side of the supporting part 112 near the first limiting part 113 can be countersunk. This prevents the nut of the fixing bolt from protruding from the surface of the first fixing part 111 after the fixing bolt is used to fix it, thus avoiding affecting the movable distance of the first mating part 123 within the first hanging groove 114. This ensures the adaptive adjustment function of the splicing screen 20 in the direction perpendicular to the mating surface of the first fixing part 111.

[0221] Example 2

[0222] It should be noted that, unless otherwise specified, the structure in this embodiment is the same as that in embodiment 1, except that the fixing frame 11 is different. Therefore, for the description of other structures, please refer to embodiment 1, and this embodiment will not repeat them.

[0223] Figure 17 is a schematic diagram of the axial structure of a splicing screen installation according to an embodiment of the present disclosure. Figure 18 is a schematic diagram of the side view of the splicing screen installation shown in Figure 17. Figure 19 is a schematic diagram of the enlarged structure of a partial area shown in Figure 18. Figure 20 is a schematic diagram of the axial structure of another type of fixing frame according to an embodiment of the present disclosure.

[0224] In some embodiments, as shown in Figures 18, 19, and 20, the mounting frame 11 includes a bridging frame 116 and a plurality of body frames 117; the bridging frame 116 has a strip-shaped structure, and the plurality of body frames 117 are spaced apart along the length of the bridging frame 116; the body frame 117 includes a second limiting part 1171 and a first fixing part 111, the second limiting part 1171 being connected to the first fixing part 111, and when the splicing screen 20 is in the installed state, the second limiting part 1171 forms a groove on the side near the first fixing part 111. The second mounting slot 1172 faces away from the ground; the bridging frame 116 includes a support part 1161, a hook part 1162, a bearing part 112 and a first limiting part 113. The support part 1161 is connected to the surface of the bearing part 112 away from the first limiting part 113, and the hook part 1162 is connected to the side of the bearing part 112 away from the bearing surface 1121. When the splicing screen 20 is in the installed state, the support part 1161 is limited to the first fixing part 111, and the hook part 1162 is limited in the second mounting slot 1172.

[0225] Thus, the mounting bracket 11 includes multiple body frames 117, which are connected to the mounting surface 31 of the carrier 30, ensuring that the mounting bracket 10 can be applied to more installation scenarios, such as the surface of the wall and the surface of multiple columns as mentioned above. Then, the bridging bracket 116 is connected to the multiple body frames 117, thereby providing a hanging position for multiple hangers 12 through the first hanging groove 114 formed by the first limiting part 113 on the strip-shaped bridging bracket 116, which facilitates the installation of multiple splicing screens 20 on the mounting bracket 10.

[0226] The bridging frame 116, with its strip-shaped structure, has a certain length, which is greater than or equal to the sum of the widths of multiple splicing screens 20 (e.g., the sum of the widths of 3, 5, or 8 splicing screens 20). This ensures that multiple splicing screens 20 can be installed using a single bridging frame 116, thus facilitating the fixing of multiple splicing screens 20 at the same height. Furthermore, the support part 1161 is connected to the surface of the bearing part 112 away from the first limiting part 113 and can be integrated with the bearing part 112, thereby avoiding interference between the support part 1161 and the hanger 12. This also ensures the support strength of the support part 1161 on the bearing part 112, preventing breakage in the connection between the support part 1161 and the bearing part 112. Additionally, it simplifies the structure of the mounting bracket 10 and improves the installation efficiency of the splicing screens 20.

[0227] The support portion 1161 and the first fixing portion 111 can be directly fixedly connected, that is, the support portion 1161 can be directly locked to the first fixing portion 111 by fixing bolts to achieve the limiting of the support portion 1161 on the first fixing portion 111. Of course, the support portion 1161 can also be limited to the first fixing portion 111 in other ways, as described below.

[0228] In some embodiments, as shown in FIG19 or FIG20, the main frame 117 further includes a third limiting part 1173; the third limiting part 1173 is connected to and opposite to the first fixing part 111. When the splicing screen 20 is in the installed state, the fixing bolt passes through the third limiting part 1173 and presses the support part 1161 onto the first fixing part 111.

[0229] The third limiting part 1173 has a mounting hole at the position opposite to the support part 1161, so that when one end of the fixing bolt is screwed into the mounting hole, it can abut against the support part 1161. Then, when the fixing bolt is tightened on the third limiting part 1173, the support part 1161 can be clamped between the end of the fixing bolt and the first fixing part 111, thereby realizing the limiting of the support part 1161 on the first fixing part 111.

[0230] The main frame 117 also includes a connector 1174, which connects the first fixing part 111 and the third limiting part 1173, so that the first fixing part 111, connector 1174, and third limiting part 1173 are connected in a U-shaped structure at their end faces, thereby ensuring that the third limiting part 1173 is connected to the first fixing part 111 while being relatively disposed. The first fixing part 111, connector 1174, and third limiting part 1173 can be an integrated structure to ensure the structural strength of the main frame 117. Furthermore, when the main frame 117 includes the connector 1174, the support part 1161 can be supported by the connector 1174 while being limited on the first fixing part 111, ensuring the reliability of the support part 1161's upper limit on the first fixing part 111.

[0231] In some other embodiments, as shown in FIG21, the surface of the first fixing part 111 facing away from the first mating surface 1112 has a protrusion 1175, and the main body frame 117 also includes a locking part 1176 connected to the middle of the protrusion 1175 and disposed opposite to the first fixing part 111. When the splicing screen 20 is in the installed state, the fixing bolt is fixedly connected to the locking part 1176, and the support part 1161 is clamped between the end of the protrusion 1175 and the nut of the fixing bolt.

[0232] The locking part 1176 has a mounting hole opposite the support part 1161, so that when one end of the fixing bolt is screwed into the mounting hole, it can abut against the support part 1161. Then, when the fixing bolt is tightened on the locking part 1176, the support part 1161 can be clamped between the nut of the fixing bolt and the end of the protrusion 1175, thereby realizing the limiting of the support part 1161 on the first fixing part 111.

[0233] The locking part 1176 is connected to the middle of the protrusion 1175 so that the fixing bolt has enough screwing distance after being screwed into the mounting hole on the locking part 1176, thereby ensuring that the nut of the fixing bolt can abut against the support part 1161 when the fixing bolt is screwed onto the locking part 1176.

[0234] Optionally, the locking part 1176 can be connected to the side of the protrusion 1175 facing away from the bearing part 112, so that when the support part 1161 is limited on the first fixing part 111, the threaded section of the fixing bolt can be used to support the support part 1161, thereby ensuring the stability of the support part 1161 in the upper limit of the first fixing part 111.

[0235] Optionally, a retaining washer is fitted onto the fixing bolt, and the retaining washer is located between the support portion 1161 and the nut of the fixing bolt. In this way, the retaining washer fitted onto the fixing bolt increases the clamping area of ​​the support portion 1161, thereby ensuring the stability of the support portion 1161 in its limiting position.

[0236] In conjunction with the case where the first fixing part 111 in the above embodiment 1 has multiple sets of strip holes 1111, the first fixing part 111 in this embodiment can not only be connected to the surface (mounting surface 31) of the carrier 30 when it is a wall, but also to the surface of the carrier 30 when it is a column.

[0237] In some embodiments, the first fixing part 111 is used to connect to the surface of the carrier 30, which is a column.

[0238] For example, as shown in Figure 17, the video wall 20 is mounted on the surface of multiple columns (carriers 30) via mounting brackets 10.

[0239] Example 3

[0240] Figure 22 is a side view of another splicing screen installation according to an embodiment of this disclosure, and Figure 23 is an enlarged view of a partial area shown in Figure 22. As shown in Figures 22 and 23, the mounting bracket 10 includes a fixing frame 11 and a hanging bracket 12. The fixing frame 11 includes a first fixing part 111, a bearing part 112, and a first limiting part 113. The first fixing part 111 has a first contact surface 1112, which is used to contact the mounting surface 31 of the carrier 30, and the first fixing part 111 is used to connect to the mounting surface 31 of the carrier 30. The bearing part 112 is connected to the side of the first fixing part 111 away from the first contact surface 1112 and has a bearing surface 1121. The first limiting part 113 is connected to the bearing surface 1121. The hanging bracket 12 includes a second fixing part. 121. Connecting part 122 and first mating part 123. The second fixing part 121 has a second contact surface 1211, which is used to contact the back of the splicing screen 20. The second fixing part 121 is used to connect the back of the splicing screen 20. The connecting part 122 is connected to the side of the second fixing part 121 away from the second contact surface 1211. The first mating part 123 is connected to the connecting part 122. The first mating part 123 is used to cooperate with the first limiting part 113. When the splicing screen 20 is in the installed state, the first mating part 123 is limited in the first hanging groove 114. The first hanging groove 114 is surrounded by the first limiting part 113, the bearing surface 1121 and the first fixing part 111, or it is surrounded by the first limiting part 113, the bearing surface 1121 and the mounting surface 31.

[0241] In this embodiment, the mounting bracket 10 includes a fixing bracket 11 and a hanging bracket 12, which fixes the splicing screen 20 on the mounting surface 31 of the carrier 30, thereby simplifying the installation of the splicing screen 20 and improving installation efficiency. When the splicing screen 20 is in the installed state, the first mating part 123 of the hanging bracket 12 is limited within the first hanging groove 114 formed by the first limiting part 113, the bearing surface 1121, and the first fixing part 111 or the mounting surface 31. At this time, based on the locking of multiple splicing screens 20, the first mating part 123 can move within the first hanging groove 114, thereby realizing the adaptive adjustment of the splicing screen 20 in the direction perpendicular to the mounting surface 31 (such as the first direction X), so as to reduce or even avoid the force of the splicing screen 20 along the direction perpendicular to the mounting surface 31, and facilitate the extension of service life.

[0242] In some embodiments, as shown in FIG23, the first fixing part 111 is used to connect to the mounting surface 31 which forms a first angle θ1 with the horizontal plane; when the splicing screen 20 is in the installed state, the bearing surface 1121 is the surface of the bearing part 112 facing away from the ground, so that the first limiting part 113 is located on the side of the bearing part 112 facing away from the ground; when the splicing screen 20 is in the installed state, the first mating part 123 is connected to the surface of the connecting part 122 facing the ground.

[0243] Optionally, the mounting surface 31 connecting the first fixing part 111 forms a first angle θ1 with the horizontal plane that is greater than or equal to 80 degrees and less than or equal to 100 degrees. For example, the first angle θ1 between the mounting surface 31 and the horizontal plane is 80 degrees, 82 degrees, 84 degrees, 86 degrees, 88 degrees, 90 degrees, 92 degrees, 94 degrees, 96 degrees, 98 degrees, 100 degrees, etc.; preferably, the first angle θ1 between the mounting surface 31 and the horizontal plane is 90 degrees.

[0244] In addition, the mounting surface 31 is not a plane in the strict sense, but has certain protrusions and / or depressions. After multiple splicing screens 20 are locked together, the bracket 12 can move in the first mounting groove 114 along the direction perpendicular to the mounting surface 31 (first direction X), ensuring the flatness of multiple splicing screens 20, while avoiding stress between two splicing screens 20 that are locked together, thereby extending the service life of the splicing screens 20.

[0245] Specifically, when the splicing screen 20 is hung in the first mounting slot 114 of the fixed frame 11 based on the bracket 12, it can be as shown in Figure 23, where the recess of the mounting surface 31 causes the first mating part 123 to move to a position that contacts the first limiting part 113, or it can be as shown in Figure 24, where the protrusion of the mounting surface 31 causes a certain gap between the first mating part 123 and the first limiting part 113.

[0246] In some embodiments, the remaining amount of the width of the exposed receiving surface 1121 of the receiving portion 112 in the first direction X minus the width of the free end of the first mating portion 123 in the first direction X is denoted as the target amount of movement, which is greater than or equal to 5 mm and less than or equal to 15 mm.

[0247] In other words, the remaining amount of movement of the first mounting groove 114 in the first direction X, after deducting the size of the first mating part 123 it accommodates, is greater than or equal to 5 mm and less than or equal to 15 mm. This ensures that the first mating part 123 has sufficient room to move within the first mounting groove 114, thereby avoiding stress between the first mating part 123 and the first limiting part 113 due to the recess of the mounting surface 31, and avoiding stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the protrusion of the mounting surface 31.

[0248] For example, the target activity levels are 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, etc.

[0249] Of course, the target activity can also be other values, as long as the movable distance of the first mating part 123 in the first hook groove 114 along the first direction X is greater than or equal to the flatness of the mounting surface 31. This can avoid stress between the first mating part 123 and the first limiting part 113 due to the concavity of the mounting surface 31, and avoid stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the convexity of the mounting surface 31. Alternatively, the movable distance of the first mating part 123 in the first hook groove 114 can be slightly less than the flatness of the mounting surface 31, so as to avoid large stress between the first mating part 123 and the first limiting part 113 due to the concavity of the mounting surface 31, and avoid large stress between the first mating part 123 and the first fixing part 111 or the mounting surface 31 due to the convexity of the mounting surface 31.

[0250] In some embodiments, as shown in Figures 24 and 25, the first limiting portion 113 has a first surface 1132 located near the first mating portion 123. The first surface 1132 forms a second angle θ2 with the bearing surface 1121 and the direction near the first fixing portion 111. The second angle θ2 is an obtuse angle. The first mating portion 123 has a second surface 1232 located near the first limiting portion 113. The second surface 1232 forms a third angle θ3 with the surface of the connecting portion 122 facing the first limiting portion 113 and the direction near the second fixing portion 121. The third angle θ3 is an obtuse angle.

[0251] Thus, by setting the first surface 1132 and the second surface 1232 to be inclined, it is convenient to guide the first limiting part 113 to the first mating part 123, thereby facilitating the hanging of the bracket 12 in the first hanging groove 114 and improving the installation efficiency of the splicing screen 20; in addition, when the first surface 1132 and the second surface 1232 are in contact, the first limiting part 113 can support the first mating part 123, thereby further improving the stability of the bracket 12 hanging on the fixed frame 11.

[0252] Optionally, the second included angle θ2 and the third included angle θ3 are of equal degree, so that when the first surface 1132 and the second surface 1232 come into contact, it is a surface contact, thereby increasing the support area of ​​the first limiting part 113 on the first mating part 123. The first surface 1132 and the second surface 1232 can fit together and guide each other, thereby facilitating the hanging bracket 12 in the first hanging groove 114 and improving the installation efficiency of the splicing screen 20.

[0253] For example, the second included angle θ2 and the third included angle θ3 are greater than 90 degrees and less than or equal to 145 degrees, such as the second included angle θ2 and the third included angle θ3 being 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees or 145 degrees, etc.

[0254] Specifically, the first surface 1132 of the first limiting part 113 near the first mating part 123 and the bearing surface 1121 of the bearing part 112, as well as the second surface 1132 of the first mating part 123 near the first limiting part 113 and the side surface of the connecting part 122 facing the first limiting part 113, can be set as an arc transition to avoid stress concentration between the first limiting part 113 and the bearing part 112, and between the first mating part 123 and the connecting part 122.

[0255] In some embodiments, as shown in FIG26, the mounting bracket 10 further includes a bolt 13; the connecting portion 122 has a through threaded hole (not shown in the figure); the first mating portion 123 has a second surface 1232 on the side near the first limiting portion 113; the second surface 1232 has a first slot 1236 extending in a direction perpendicular to the extension of the first mating portion 123, the first slot 1236 exposing the threaded hole on the connecting portion 122; as shown in FIG27, the first limiting portion 113 has a first surface 1132 on the side near the first mating portion 123, the first surface 1132 has a second slot 1135 extending in a direction perpendicular to the extension of the first limiting portion 113; when the splicing screen 20 is in the installed state, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0256] For example, the extension direction of the first mating part 123 is the length direction of the first mating part 123, as shown by the Z direction in Figure 26; the extension direction of the first limiting part 113 is the length direction of the first limiting part 113, as shown by the Z direction in Figure 27; the direction perpendicular to the extension direction of the first mating part 123 is the height direction of the first mating part 123, as shown by the second direction Y in Figure 26; the direction perpendicular to the extension direction of the first limiting part 113 is the height direction of the first limiting part 113, as shown by the second direction Y in Figure 27; the second direction Y is perpendicular to the bearing surface 1121, or it can be perpendicular to the surface of the connecting part 122 near the bearing surface 1121. The third direction Z is the overall extension direction of the mounting bracket.

[0257] In one specific embodiment, the connecting portion 122 has a threaded hole extending along a second direction Y; the second direction Y is a direction perpendicular to the bearing surface 1121 or a direction perpendicular to the surface of the connecting portion 122 on the side close to the bearing surface 1121; the first mating portion 123 has a first slot 1236 extending along the second direction Y, the first slot 1236 exposing the threaded hole located on the connecting portion 122; the first limiting portion 113 has a second slot 1135 extending along the second direction Y; when the splicing screen 20 is in the installed state, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0258] The threaded hole extends through the entire thickness of the connecting part 122; the threaded hole is located at the end of the connecting part 122 away from the second fixing part 121, so a first slot 1236 is provided on the first mating part 123 to expose the threaded hole, which can prevent the bolt 13 from interfering with the first mating part 123 when tightened.

[0259] Referring to Figure 24, when the splicing screen 20 is in the installation state shown in Figure 24, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0260] With the splicing screen 20 in the installation state shown in Figure 23, one end of the bolt 13 is screwed into the threaded hole and passes continuously through the first slot 1236 and the second slot 1135, abutting against the bearing surface 1121. In this way, when the first limiting part 113 abuts against the first mating part 123, the bolt 13 can be avoided by the second slot 1135, or in other words, the bolt 13 can be accommodated by the second slot 1135, eliminating the influence of the bolt 13 on the reserved space in the first direction X, which is beneficial to reducing the overall size of the mounting bracket 10 installed in the first direction X.

[0261] Bolt 13 is a helical connection within the threaded hole of connecting part 122. As shown in Figures 24 and 28, after the end of bolt 13 abuts against the bearing surface 1121 of bearing part 112, bolt 13 can be tightened further. This allows adjustment of the distance between connecting part 122 and bearing surface 1121 in the second direction Y when connecting part 122 cannot rotate synchronously, thus achieving adjustment of the bracket 12 in the second direction Y. This ensures that all splicing screens 20 are stably in contact with the fixing frame 11, preventing the bracket 12 from being suspended in some areas, and effectively guaranteeing the locking and fixing between multiple splicing screens 20.

[0262] The nut end of the bolt 13 can be a polygonal structure, so that the bolt 13 can be tightened or loosened by a wrench, or the nut end can have a limiting groove (such as a cross or slotted structure), so that the bolt 13 can be tightened or loosened by a corresponding screwdriver.

[0263] As shown in Figure 28, after adjusting the position of the bracket 12 in the second direction Y by continuing to tighten the bolts 13, there is no contact between the first limiting part 113 and the connecting part 122, and between the first mating part 123 and the bearing part 112. At this time, the bracket 12 is supported on the fixed frame 11 only by the end of the bolt 13 abutting against the bearing surface 1121. When adjusting the height of the splicing screen 20 by the bolts 13, one splicing screen 20 can correspond to multiple bolts 13, so that the parallelism of the upper surface of the splicing screen 20 can be ensured when adjusting the height of the splicing screen 20 by using multiple bolts 13 that are spaced apart.

[0264] Optionally, the first slot 1236 extends from the second surface 1232 to the second side 1235 of the first mating portion 123 opposite to the second surface 1232, and / or, the second slot 1135 extends from the first surface 1132 to the first side 1134 of the first limiting portion 113 opposite to the first surface 1132. This ensures sufficient clearance for the bolt 13, preventing interference during installation and improving installation efficiency; it also reduces the weight of the mounting bracket.

[0265] In some embodiments, as shown in FIG25, the first limiting part 113 has a first side surface 1134 away from the first fixing part 111, and the first mating part 123 has a second side surface 1235 away from the second fixing part 121; the first side surface 1134 is perpendicular to the extension surface of the bearing surface 1121, and the second side surface 1235 is perpendicular to the extension surface of the surface of the connecting part 122 near the bearing part 112.

[0266] In some embodiments, as shown in FIG25, the first side surface 1134 is perpendicular to the plane where the bearing surface 1121 is located, and the second side surface 1235 is perpendicular to the plane where the surface of the connecting portion 122 near the bearing portion 112 is located.

[0267] Thus, combining the inclined first surface 1132 and the second surface 1232, the longitudinal section of the first limiting part 113 and the first mating part 123 in this embodiment is trapezoidal in the second direction Y. Compared with the parallelogram-like structure of the longitudinal section of the first limiting part 113 and the first mating part 123 in Embodiment 1, this Embodiment 3 increases the size of the end of the first limiting part 113 near the bearing part 112 in the first direction X, that is, increases the connection area between the first limiting part 113 and the bearing part 112 in the first direction X; at the same time, it also increases the size of the end of the first mating part 123 near the connecting part 122 in the first direction X, that is, increases the connection area of ​​the connecting part 122 of the first mating part 123 in the first direction X; thus, the bidirectional support strength of the first limiting part 113 and the first mating part 123 can be improved, thereby ensuring the stability of the connection of the hanger 12 on the fixed frame 11.

[0268] As shown in Figure 23, when the first limiting part 113, the bearing part 112, the first mating part 123 and the connecting part 122 are installed, their outer shapes are "U"-shaped, and the four together form a rectangular structure. Compared with the parallelogram structure in Embodiment 1, the rectangular structure is more resistant to shear deformation when subjected to lateral force, thereby improving the support stability.

[0269] As shown in Figure 24, when the first fixing part 111, the bearing part 112, the first limiting part 113, the second fixing part 121, the connecting part 122, and the first mating part 123 are installed, they form a hollow rectangular structure in the middle section, which helps to improve the support stability.

[0270] In some embodiments, as shown in FIG25, the supporting portion 112 has a third side surface 1123 away from the first fixing portion 111, and the connecting portion 122 has a fourth side surface 1221 away from the second fixing portion 121; the first side surface 1134 is coplanar with the third side surface 1123, and the second side surface 1235 is coplanar with the fourth side surface 1221.

[0271] In other words, compared to Embodiment 1, this embodiment moves the first limiting part 113 to the end of the bearing part 112 away from the first fixing part 111, and moves the first mating part 123 to the end of the connecting part 122 away from the second fixing part 121. This edge-mounted design can shorten the dimensions of the bearing part 112 and the connecting part 122 in the first direction X, while ensuring that the first mounting groove has a reasonable target range of motion. That is, it shortens the overall width of the fixing frame 11 and the hanging frame 12 in the first direction X. This ultra-thin design of the mounting bracket 10 saves installation space and improves the aesthetic effect of the whole installation. At the same time, when the first limiting part 113 contacts the second mating surface 1211 and the first mating part 123 contacts the mounting surface 31, the first limiting part 113 and the bearing part 112, which are connected as one unit, directly contact the splicing screen 20, and the connecting part 122 and the first mating part 123, which are connected as one unit, directly contact the wall surface. This can improve the strength against shear stress, thereby ensuring installation stability.

[0272] Optionally, as shown in Figure 24, the overall width of the fixing bracket 11 in the first direction X is between 15mm and 25mm; the overall width of the hanging bracket 12 in the first direction X is between 15mm and 25mm. For example, the overall widths of the fixing bracket 11 and the hanging bracket 12 in the first direction X are 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, etc.

[0273] Optionally, as shown in Figure 24, the protrusion on the mounting surface 31 creates a certain gap between the first mating part 123 and the first limiting part 113. Furthermore, under extreme installation conditions, i.e., when the gap is at its maximum, the first side surface 1134, the third side surface 1123, and the second mating surface 1211 are coplanar; the second side surface 1235, the fourth side surface 1221, and the first mating surface 1112 are coplanar. Thus, the first limiting part 113 directly contacts both the second fixing part 121 and the splicing screen 20; the first mating part 123 directly contacts both the first fixing part 111 and the carrier 30, providing more stress points for support and improving support stability.

[0274] In some embodiments, as shown in FIG23 or FIG24, the first limiting part 113 has a cross-section in the shape of a trapezoid in a plane parallel to the first direction X and the second direction Y; the first mating part 123 has a cross-section in the shape of a trapezoid in a plane parallel to the first direction X and the second direction Y; the first direction X is perpendicular to the mounting surface 31, and the second direction Y is perpendicular to the bearing surface 1121; wherein, the length of the base of the first trapezoid near the bearing part 112 is greater than the length of the base away from the bearing part 112; the length of the base of the second trapezoid near the connecting part 122 is greater than the length of the base away from the connecting part 122. In this way, by increasing the connection area between the first limiting part 113 and the bearing part 112 in the first direction X, and increasing the connection area of ​​the connecting part 122 of the first mating part 123 in the first direction X, the support strength of the fixing frame 11 and the hanging bracket 12 can be improved, ensuring the stability of the hanging bracket 12 connected to the fixing frame 11.

[0275] In some embodiments, as shown in FIG23 or FIG24, when the screen is in the installed state, the free end of the first limiting part 113 contacts the connecting part 122, and the free end of the first mating part 123 contacts the bearing surface 1121. The shortest distance from the free end of the first limiting part 113 to the bearing part 112 is equal to the shortest distance from the free end of the first mating part 123 to the connecting part 122.

[0276] This embodiment of the invention uses the first slot 1236 and the second slot 1135 to avoid the bolt 13, thereby reducing the size of the mounting bracket in the first direction X, thus reducing weight, saving materials, lowering costs, saving installation space, and improving the aesthetics of the overall installation. Simultaneously, the first limiting part 113 and the first mating part 123 are trapezoidal in shape in the XY longitudinal section (or end face) to enhance the structural strength of the fixing frame 11 and the hanging frame 12, thereby compensating for the strength loss due to the thinning of the mounting bracket. Furthermore, the first side 1134 of the first limiting part 113 is coplanar with the third side 1123 of the bearing part 112, and the second side 1235 of the first mating part 123 is coplanar with the fourth side 1221 of the connecting part 122. During installation, if in direct contact with the wall and the splicing screen 20, the strength against shear stress can be further improved, thereby ensuring installation stability. Meanwhile, the first side 1134 of the first limiting part 113 is coplanar with the third side 1123 of the bearing part 112, and the second side 1235 of the first mating part 123 is coplanar with the fourth side 1221 of the connecting part 122. That is, the first limiting part 113 is set to the maximum extent on the side of the bearing part 112 away from the first fixing part 111, and the first mating part 123 is set to the maximum extent on the side of the connecting part 122 away from the second fixing part 121. Under the premise of reducing the thickness of the mounting bracket, the adjustment space of the fixing bracket 11 and the hanging bracket 12 in the first direction X is still ensured, so that they can be freely adjusted in the first direction X, ensuring the flatness of the splicing screen 20 installation.

[0277] In some embodiments, as shown in Figures 29 and 30, the support portion 112 has a groove 1122 located on the support surface 1121; the groove 1122 communicates with the second slot 1135, and the length direction of the groove 1122 (such as the first direction X) is parallel to the plane perpendicular to the first mating surface 1112; when the splicing screen 20 is in the installed state, one end of the bolt 13 that abuts against the support surface 1121 is limited in the groove 1122.

[0278] Thus, by providing a groove 1122 on the bearing surface 1121 of the bearing part 112, and limiting one end of the bolt 13 within the groove 1122, the bolt 13 is allowed to move along the first direction X, while limiting its movement along the third direction Z. This ensures the self-adjustment of the splicing screen 20 in the first direction X, while preventing the splicing screen 20 from moving in the third direction Z, thereby ensuring the stability of the splicing screen 20 on the mounting bracket 10.

[0279] In addition, as shown in Figure 30, the slide groove 1122 is connected to the second slot 1135, and the slide groove 1122 extends along the first direction X to the first mating surface 1112, that is, it extends horizontally through the entire fixing frame 11, thereby ensuring the sliding space of the bolt 13, and thus ensuring the adaptive adjustment of the splicing screen 20 in the first hanging groove.

[0280] Optionally, the width of the second slot 1135 is greater than or equal to the width of the groove 1122.

[0281] Of course, the length of the slide groove 1122 can also be set slightly shorter. For example, since the threaded hole on the connecting part 122 is not located at the edge of the connecting part 122, one end of the slide groove 1122 does not need to extend to the first mating surface 1112. In this way, the self-adaptive adjustment of the splicing screen 20 in the first mounting groove is ensured, while also facilitating the structural strength of the supporting part 112.

[0282] Additionally, as shown in Figure 26, in the case where one video wall 20 corresponds to multiple bolts 13, the bearing surface 1121 of the bearing portion 112 may have only one groove 1122 for limiting one bolt 13, or the bearing surface 1121 may have grooves 1122 for limiting each bolt 13. For example, one video wall 20 corresponds to two bolts 13, and the bearing surface 1121 of the bearing portion 112 has only one groove 1122 for limiting one bolt 13.

[0283] In some embodiments, as shown in FIG23, the mounting surface 31 connecting the first fixing part 111 forms a first angle θ1 with the horizontal plane, and the extension surface of the first mating surface 1112 (i.e., the mounting surface 31) forms a fourth angle θ4 with the bearing surface 1121, wherein the first angle θ1 and the fourth angle θ4 are equal in degree.

[0284] This ensures that after the first contact surface 1112 of the first fixing part 111 is in contact with the mounting surface 31 of the carrier 30, the bearing surface 1121 of the bearing part 112 is always parallel to the horizontal plane. This facilitates the stable support of the bracket 12 by the bearing surface 1121, and at the same time ensures the stable suspension of the splicing screen 20 on the fixing frame 11. It also prevents the bracket 12 from moving in the direction perpendicular to the first contact surface 1112 when it is attached to the fixing frame 11, and thus prevents the splicing screen 20 from moving in the direction perpendicular to the first contact surface 1112. This further avoids the interaction force between adjacent splicing screens 20.

[0285] Optionally, the angle between the extension surface of the second bonding surface 1211 (i.e., the back side of the splicing screen 20) and the surface of the connecting portion 122 facing the first limiting portion 113 is 90 degrees; and / or, the angle between the extension surface of the first bonding surface 1112 (i.e., the mounting surface 31) and the bearing surface is 90 degrees.

[0286] In this design, the first angle θ1 between the mounting surface 31 of the carrier 30 and the horizontal plane is 90 degrees, meaning the mounting surface 31 of the carrier 30 is a vertical surface. This ensures that after the splicing screen 20 is hung on the fixing frame 11 via the hanger 12, the display surface of the splicing screen 20 remains vertical, thereby guaranteeing the display effect after installation.

[0287] In some embodiments, as shown in FIG24, the hanger 12 further includes a first reinforcing part 124 integrally formed with the second fixing part 121; the first reinforcing part 124 is disposed opposite to the connecting part 122 and is located on the side of the connecting part 122 away from the first mating part 123.

[0288] Optionally, the ratio of the dimension of the first reinforcing part 124 in the first direction X to the dimension of the connecting part 122 in the first direction X is between 1:6 and 1:2.

[0289] For example, the ratio of the dimension of the first reinforcing part 124 in the first direction X to the dimension of the connecting part 122 in the first direction X is 1:6, 1:5, 1:4, 1:3, etc. The dimension of the first reinforcing part 124 in the first direction X is less than half the dimension of the connecting part 122 in the first direction X. The shorter first reinforcing part 124 can ensure that the bracket 12 has a certain structural strength, and can also reduce the weight of the bracket 12, saving material costs.

[0290] The two sides of the second fixing part 121 are connected to the connecting part 122 and the first reinforcing part 124 respectively (e.g., integrally formed). For example, the ratio of the dimension of the first reinforcing part 124 in the first direction X to the dimension of the connecting part 122 in the first direction X is 1:2, and the structure is approximately U-shaped with the connection end face. In this way, the structure of the bracket 12 is equivalent to the structure of the channel steel, thereby effectively ensuring the structural strength of the bracket 12, and thus ensuring the stability of the splicing screen 20 installed on the mounting bracket 10.

[0291] In some implementations, as shown in FIG26, the bracket 12 is a strip structure, and one bracket 12 is used to be fixedly connected to one splicing screen 20, that is, one splicing screen 20 corresponds to one bracket 12.

[0292] The strip-shaped bracket 12 has a certain length, which is equal to or slightly less than the width of a video wall 20, so that one bracket 12 can be used to install one video wall 20. In addition, the strip-shaped bracket 12 facilitates leveling when the second fixing part 121 of the bracket 12 is fixedly connected to the back of the video wall 20. That is, it is easy to ensure that the length direction of the bracket 12 is parallel to the upper surface of the video wall 20, and at the same time, it simplifies the fixed installation of the bracket 12 on the back of the video wall 20.

[0293] In other embodiments, as shown in FIG31, the bracket 12 is a block structure, and at least two brackets 12 are used to be fixedly connected to the same splicing screen 20, that is, one splicing screen 20 corresponds to multiple brackets 12.

[0294] Among them, the bracket 12 is a block structure, that is, the length of the bracket 12 is relatively short, and multiple brackets 12 are required to install a splicing screen 20. In addition, the bracket 12 is set as a block structure, which helps to save materials for the bracket 12, thereby saving costs. At the same time, it is easy to make the bracket 12 lightweight, so as to reduce the weight borne by the fixing frame 11 and ensure the stability of the fixing frame 11 and the mounting surface 31 of the carrier 30.

[0295] Optionally, as shown in Figures 32 and 33, the bracket 12 further includes a pin 125 fixed to the side of the second fixing part 121 away from the connecting part 122; when the splicing screen 20 is in the installed state, the pin 125 passes through the limiting hole 201 on the housing of the splicing screen 20 to position the bracket, thereby preventing the block-shaped bracket 12 from rotating.

[0296] In this embodiment of the present disclosure, as shown in FIG26, the specific structure of the hanger 12 may be a structure in which the second fixing part 121, the connecting part 122 and the first mating part 123 are integrally formed. As shown in FIG27, the specific structure of the fixing frame 11 may be a structure in which the first fixing part 111, the bearing part 112 and the first limiting part 113 are integrally formed, or the bearing part 112 and the first limiting part 113 may be integrally formed and limitedly connected to the first fixing part 111.

[0297] In some embodiments, as shown in FIG27, the fixing frame 11 is a strip structure, and the first fixing part 111, the bearing part 112 and the first limiting part 113 are an integral structure.

[0298] The strip-shaped fixing frame 11 has a certain length, and the length of the fixing frame 11 is greater than or equal to the sum of the widths of multiple splicing screens 20 (such as the sum of the widths of 2, 3, 5, 8, etc. splicing screens 20), so as to ensure that multiple splicing screens 20 can be installed through one fixing frame 11, thereby making it easier to ensure that multiple splicing screens 20 are fixed at the same height.

[0299] In addition, for cases where the length of a single mounting bracket 11 is relatively short, to ensure that a row of splicing screens 20 is at the same height, adjacent mounting brackets 11 can be connected via an interlocking interface. This ensures that multiple mounting brackets 11 of a corresponding row of splicing screens 20 are at the same height, i.e., multiple mounting brackets 11 are located on the same straight line. An example of the interlocking interface is that the first fixing part 111 has a protrusion and a recess on two opposite sides in the third direction Z, with a gap fit between the protrusion and the recess. During installation, they are aligned and interlocked to achieve the alignment and splicing of multiple mounting brackets 11, thereby ensuring that multiple mounting brackets 11 of a corresponding row of splicing screens 20 are at the same height.

[0300] The first fixing part 111, the bearing part 112 and the first limiting part 113 are integrated into one structure, which facilitates the strengthening of the structural strength of the fixing frame 11. At the same time, the fixing frame 11 is a strip structure, so that the hanging frame 12 can be hung at any position of the fixing frame 11, thus facilitating the hanging of the splicing screen 20 at any position of the fixing frame 11.

[0301] The bearing portion 112 is connected to the side of the first fixing portion 111 that is away from the first contact surface 1112. The connection between the surface of the bearing portion 112 that is away from the bearing surface 1121 and the first fixing portion 111 is a rounded transition, thereby avoiding stress concentration at the connection between the bearing portion 112 and the first fixing portion 111.

[0302] In some embodiments, as shown in FIG28, the first fixing part 111 and the bearing part 112 are connected to form an L-shaped structure at the end face. When the fixing frame 11 is connected to the mounting surface 31 of the carrier 30, the first limiting part 113, the bearing surface 1121, and the mounting surface 31 form a first hanging groove 114.

[0303] The first fixing part 111 and the bearing part 112 are connected in an L-shaped structure at the end face. The first fixing part 111 can be fixed on the mounting surface 31 of the carrier 30 on the side of the bearing part 112 away from the first limiting part 113. At the same time, it can prevent the nuts of the fixing bolts for locking the first fixing part 111 from being located in the first hanging groove 114, which would affect the movable distance of the first mating part 123 in the first hanging groove 114, thereby ensuring the adaptive adjustment function of the splicing screen 20 in the first direction X.

[0304] Meanwhile, the first fixing part 111 and the bearing part 112 are connected in an L-shaped structure at the end face to ensure that the structure of the fixing frame 11 is simple. This is conducive to achieving a thin and light fixing frame 11, thereby improving the aesthetic effect when the installation is completed.

[0305] In some embodiments, as shown in FIG27, the first fixing part 111 has multiple sets of strip holes 1111 spaced apart along the width direction (second direction Y); each set of strip holes 1111 includes multiple strip holes 1111 spaced apart along the length direction (i.e., third direction Z) of the first fixing part 111, and the length direction of each strip hole 1111 is parallel to the arrangement direction (i.e., third direction Z) of the multiple strip holes 1111; adjacent sets of strip holes 1111 are staggered in the length direction (i.e., third direction Z) of the first fixing part 111.

[0306] Among them, the strip-shaped holes 1111 are through holes of a certain length, such as oblong holes or rectangular holes. This allows for flexible adjustment of the position of the fixing bolts within the corresponding strip-shaped holes 1111 in the third direction X when the first fixing part 111 is fixed to the mounting surface 31 of the carrier 30, thereby finding an optimal installation position on the carrier 30 and ensuring the installation effect. Furthermore, the multiple strip-shaped holes 1111 also ensure the stability of the fixing frame 11 to the mounting surface 31 of the carrier 30.

[0307] Optionally, the multiple sets of strip-shaped holes 1111 include a first set of strip-shaped holes and a second set of strip-shaped holes, with the first set of strip-shaped holes being closer to the bearing portion 112 than the second set of strip-shaped holes; the first set of strip-shaped holes includes a plurality of first strip-shaped holes 1111a spaced apart along the length direction (third direction Z) of the first fixing portion 111, and the second set of strip-shaped holes includes a plurality of second strip-shaped holes 1111b spaced apart along the length direction (third direction Z) of the first fixing portion 111; the length of the first strip-shaped holes 1111a is greater than the length of the second strip-shaped holes 1111b; every two first strip-shaped holes 1111a in the first set of strip-shaped holes form a group of strip-shaped holes 1111c; the hole gap between two adjacent groups of strip-shaped holes 1111c in the length direction (third direction X) of the first fixing portion 11 corresponds to one second strip-shaped hole 1111b; the hole gap L1 between two first strip-shaped holes 1111a in the group of strip-shaped holes 1111c is smaller than the hole gap L2 between two adjacent groups of strip-shaped holes 1111c.

[0308] In this design, the multiple first strip-shaped holes 1111a within the first group of strip-shaped holes are densely distributed along the third direction Z. This concentrates the installation positions of the fixing frame 11 and the carrier 30 onto the first group of strip-shaped holes. Since the first group of strip-shaped holes is closer to the bearing part 112 than the second group of strip-shaped holes, the structural strength and resistance to bending deformation are stronger at the location near the bearing part 112. Therefore, using the first group of strip-shaped holes to lock and fix the fixing frame 11 ensures installation stability. At the same time, the hole gap L2 between two adjacent strip-shaped hole groups 1111c in the length direction of the first fixing part 11 is greater than the hole gap L1 between two first strip-shaped holes 1111a in the strip-shaped hole group 1111c, ensuring the structural strength in the row direction where the first group of strip-shaped holes is located.

[0309] The gap L2 between two adjacent strip-shaped holes 1111c in the length direction of the first fixing part 11 corresponds to a second strip-shaped hole 1111b, and the projection of the second strip-shaped hole 1111b in the second direction Y covers the projection of the corresponding hole gap in the second direction Y.

[0310] Optionally, the ratio of the length of the first strip-shaped hole 1111a to the length of the second strip-shaped hole 1111b ranges from 2 to 8. The ratio of the length of the first strip-shaped hole 1111a to the hole gap L2 ranges from 2 to 8. The ratio of the length of the second strip-shaped hole 1111b to the hole gap L2 ranges from 0.9 to 1.2. For example, the ratio of the length of the first strip-shaped hole 1111a to the length of the second strip-shaped hole 1111b ranges from 4 to 8, thus concentrating the first strip-shaped hole 1111a more on the side closer to the support portion 112. The ratio of the length of the second strip-shaped hole 1111b to the hole gap L2 ranges from 0.9 to 1, that is, the size of the second strip-shaped hole 1111b is equal to the hole gap L2, ensuring that the missing area is filled while ensuring structural strength.

[0311] The shorter second strip-shaped hole 1111b fills the installation gap caused by the hole gap between two adjacent strip-shaped hole groups 1111c, ensuring that fixation can be performed precisely at the hole gap position between two adjacent strip-shaped hole groups 1111c, thus avoiding the impact of the fixing frame 11 on the fixation when there is a gap in the carrier 30. For example, in the case where the mounting surface 31 is the surface of multiple columns, the gap between two adjacent columns constitutes a gap in the carrier 30. In this case, for the first fixing part 111 with multiple sets of strip-shaped holes 1111, the gap can be avoided, and the fixing frame 11 can be fixed to multiple columns by holes on the first fixing part 111 corresponding to the area where the columns are located.

[0312] In some embodiments, as shown in FIG1, the first fixing part 111 is used to connect to the surface (mounting surface 31) of the carrier 30, which is a planar wall. The first mating surface 1112 and the mounting surface 31 of the first fixing part 111 are both planar; the second mating surface 1211 and the back surface of the splicing screen 30 are both planar.

[0313] Of course, considering the case where the first fixing part 111 has multiple sets of strip-shaped holes 1111, the first fixing part 111 can also be connected to the surface of the carrier 30, which is a column. For example, as shown in FIG17, the video wall 20 is mounted on the surface of multiple columns (carrier 30) via the mounting bracket 10. The multiple columns are arranged horizontally side by side.

[0314] In other embodiments, as shown in Figures 34 and 35, the first fixing part 111 is used to connect to the surface (mounting surface 31) of the carrier 30, which is a curved wall or a curved building column.

[0315] Specifically, the first bonding surface 1112 is a curved surface, and the curvature of the first bonding surface 1112 is the same as the curvature of the mounting surface 31 on the carrier 30; the second bonding surface 1211 is a curved surface, and the curvature of the second bonding surface 1211 is the same as the curvature of the back of the splicing screen 30 corresponding to it.

[0316] Thus, in the scenario where the wall is flat, the mounting bracket 10 provided in this embodiment can be flexibly applied to various building environments, simplifying the installation conditions for users and improving market universality.

[0317] In some embodiments, as shown in FIG24, the fixing frame 11 further includes a second reinforcing part 115 integrally formed with the first fixing part 111; the second reinforcing part 115 is disposed opposite to the bearing part 112 and is located on the side of the bearing part 112 away from the first limiting part 113.

[0318] Optionally, the ratio of the dimension of the second reinforcing part 115 in the first direction X to the dimension of the bearing part 112 in the first direction X is between 1:6 and 1:2.

[0319] For example, the ratio of the dimension of the second reinforcing part 115 in the first direction X to the dimension of the supporting part 112 in the first direction X is 1:6, 1:5, 1:4, 1:3, etc. The dimension of the second reinforcing part 115 in the first direction X is less than half the dimension of the supporting part 112 in the first direction X. The shorter second reinforcing part 115 can ensure that the fixing frame 11 has a certain structural strength, and can also reduce the weight of the fixing frame 11, thus saving material costs.

[0320] The two sides of the first fixing part 111 are connected to the bearing part 112 and the second reinforcing part 115 respectively (e.g., integrally formed). For example, the ratio of the dimension of the second reinforcing part 115 in the first direction X to the dimension of the bearing part 112 in the first direction X is 1:2, and the structure is approximately U-shaped with the connection end face. In this way, the structure of the fixing frame 11 is equivalent to the structure of channel steel, thereby effectively ensuring the structural strength of the fixing frame 11, and thus ensuring the stability of the splicing screen 20 when it is hung on the fixing frame 11.

[0321] In some embodiments, as shown in FIG24, the direction perpendicular to the bearing surface 1121 is the second direction Y; the ratio of the dimension d1 of the second fixing part 121 in the second direction Y to the dimension d2 of the bracket 12 in the second direction X is between 0.4 and 0.7. For example, the ratio of the dimension of the second fixing part 121 in the second direction Y to the dimension of the bracket 12 in the second direction X is 0.4, 0.5, 0.6, 0.7, etc.

[0322] Optionally, the ratio of the dimension of the second fixing part 121 in the second direction Y to the dimension of the bracket 12 in the second direction X is between 0.4 and 0.5. Here, a ratio greater than or equal to 0.4 ensures that the bracket 12 has sufficient structural strength to meet installation strength requirements. A ratio less than or equal to 0.5 allows for a reduction in the size of the second fixing part 121, thereby saving material and reducing costs while ensuring the structural strength of the bracket 12 itself does not affect installation.

[0323] Optionally, the ratio of the dimension of the second fixing part 112 in the second direction Y to the dimension of the bracket 12 in the second direction Y is between 0.5 and 0.7. This effectively ensures the load-bearing strength of the bracket 12.

[0324] For ease of understanding, the above description uses a single embodiment. However, mounting brackets also include other types, and the structural features of the following embodiments are equally applicable to any of the above embodiments.

[0325] In some embodiments, the material of the mounting bracket 11 may include aluminum alloy, and the material of the hanging bracket 12 may also include aluminum alloy. For example, the mounting bracket 11 is made of aluminum alloy, which has the advantages of being lightweight and economical; similarly, the hanging bracket 12 is made of aluminum alloy, which also has the advantages of being lightweight and economical. Both the mounting bracket 11 and the hanging bracket 12 can be manufactured using an aluminum extrusion process.

[0326] Figure 36 is a partially enlarged side view of another splicing screen installation provided in this embodiment of the present disclosure, Figure 37 is a structural schematic diagram of the bracket in Figure 36, and Figure 38 is a structural schematic diagram of the fixing bracket in Figure 36.

[0327] In some embodiments, as shown in Figures 36 and 37, the direction perpendicular to the bearing surface 1121 is the second direction Y; the ratio of the dimension d1 of the second fixing part 121 in the second direction Y to the dimension d2 of the bracket 12 in the second direction X is between 0.4 and 0.5. For example, the ratio of the dimension d1 of the second fixing part 121 in the second direction Y to the dimension d2 of the bracket 12 in the second direction X is 0.4 or 0.5. By shortening the dimension of the second fixing part 121 in the second direction Y, the material of the bracket 12 can be further saved while ensuring that the function performed by the bracket 12 itself remains unchanged, thereby reducing costs.

[0328] In some embodiments, as shown in Figures 36 and 38, the fixing frame 11 further includes a bending-resistant structure 1110; the first fixing part 111 has a first end and a second end disposed opposite to each other along a third direction Z; the third direction Z is the length direction of the fixing frame 11; the bending-resistant structure 1110 extends along the direction from the first end to the second end and is connected to the side of the first fixing part 111 away from the first contact surface 1112.

[0329] In this embodiment, a bending-resistant structure 1110 is added to the first fixing part 111 so that the fixing frame 11 has a higher bending modulus in the first direction X, that is, it can be lower than the bending deformation in the larger first direction X, thereby effectively improving the installation stability of the fixing frame 11 on the carrier 30.

[0330] In some embodiments, as shown in Figures 36 and 38, the bending-resistant structure 1110 includes an intermediate bending-resistant portion 1110-1 and a fourth limiting portion 1110-2; the intermediate bending-resistant portion 1110-1 is disposed between the fourth limiting portion 1110-2 and the bearing portion 112; the fourth limiting portion 1110-2 is connected to and disposed opposite to the first fixing portion 111.

[0331] The intermediate bending-resistant portion 1110-1 and the fourth limiting portion 1110-2 are spaced apart, and simultaneously enhance the bending modulus of the first fixing portion 111. Specifically, the intermediate bending-resistant portion 1110-1 resists bending deformation of the first fixing portion 111 in the middle region, and the fourth limiting portion 1110-2 resists bending deformation of the first fixing portion 111 on the side away from the bearing portion 112. The spaced intermediate bending-resistant portion 1110-1 and the fourth limiting portion 1110-2 effectively prevent installation deformation of the fixing frame 11 under stress.

[0332] Optionally, the intermediate bending-resistant portion 1110-1 includes a first sub-portion 1110a disposed opposite to the first fixing portion 111, and a second sub-portion 1110b and a third sub-portion 1110c connecting the first sub-portion 1110a and the first fixing portion 111. The second sub-portion 1110b and the third sub-portion 1110c are respectively disposed on two opposite sides of the first sub-portion 1110a in the second direction Y. The first sub-portion 1110a, the second sub-portion 1110b, the third sub-portion 1110c and the first fixing portion 111 form a hollow tube structure. The first sub-part 1110a, the second sub-part 1110b, and the third sub-part 1110c are integrally formed with the first fixing part 111. The first sub-part 1110a, the second sub-part 1110b, the third sub-part 1110c, and the first fixing part 111 form a hollow tube structure. This hollow structure further enhances the bending modulus and also reduces the weight of the fixing frame 11.

[0333] Optionally, the fourth limiting part 1110-2 is connected to the first fixing part 111 via the second connecting member 1110-3, so that the fourth limiting part 1110-2, the second connecting member 1110-3, and the first fixing part 111 are connected in a U-shaped structure at the end face, thereby optimizing the structural strength of the fixing frame 11. In addition, the first fixing part 111, the second connecting member 1110-3, and the fourth limiting part 1110-2 can be an integrated structure, further ensuring the structural strength of the fixing frame 11.

[0334] Optionally, when the splicing screen 20 is in the installed state, at least one of the surface of the fourth limiting part 1110-2 away from the first fixing part 111 and the surface of the first sub-part 1110a away from the first fixing part 111 comes into contact with the back of the splicing screen 20.

[0335] Optionally, the surface of the fourth limiting part 1110-2 away from the first fixing part 111, the surface of the first sub-part 1110a away from the first fixing part 111, and the first side surface 1134 are coplanar. When the splicing screen 20 is in the installed state, the surface of the fourth limiting part 1110-2 away from the first fixing part 111, the surface of the first sub-part 1110a away from the first fixing part 111, and the first side surface 1134 are all in contact with the back of the splicing screen 20. Within the limited installation space between the splicing screen 20 and the wall in the first direction X, the dimensions of the intermediate anti-bending part 1110-1, the fourth limiting part 1110-2, and the second connector 1110-3 in the first direction X are arranged to the maximum extent to ensure the structural strength of the fixing frame 11.

[0336] In some embodiments, as shown in FIG36, the bending-resistant structure 1110 further includes a fifth limiting portion 1110-4; the fifth limiting portion 1110-4 is disposed opposite to the first fixing portion 111 and connected to the side of the bearing portion 112 facing away from the bearing surface 1121. The fifth limiting portion 1110-4 and the bearing portion 112 are connected as an integral structure. The fifth limiting portion 1110-4, the bearing portion 112 and the first fixing portion 111 are connected to form a U-shaped structure at the end face, thereby optimizing the structural strength of the fixing frame 11.

[0337] In some embodiments, as shown in FIG36, the first limiting portion 113 has a first side surface 1134 away from the first fixing portion 111, and the first mating portion 123 has a second side surface 1235 away from the second fixing portion 121; the first side surface 1134 is perpendicular to the extension surface of the bearing surface 1121, and the second side surface 1235 is perpendicular to the extension surface of the surface of the connecting portion 122 near the bearing portion 112. Thus, combined with the inclined first surface 1132 and the second surface 1232, the end faces of the first limiting portion 113 and the first mating portion 123 in this embodiment are trapezoidal, which can improve the bidirectional support strength of the first limiting portion 113 and the first mating portion 123, thereby ensuring the stability of the connection of the hanger 12 on the fixing frame 11.

[0338] The supporting part 112 has a third side surface 1123 away from the first fixing part 111, and the connecting part 122 has a fourth side surface 1221 away from the second fixing part 121; the first side surface 1134 is coplanar with the third side surface 1123, and the second side surface 1235 is coplanar with the fourth side surface 1221. The surface of the fourth limiting part 1110-2 away from the first fixing part 111, the surface of the first sub-part 1110a away from the first fixing part 111, and the first side surface 1134 are coplanar. In this way, the size of the bending-resistant structure 1110 in the first direction X is maximized within the minimum space between the carrier 30 and the splicing screen 20, thus effectively ensuring bending resistance.

[0339] Optionally, the fifth limiting part 1110-4 has a fifth side surface 1110-41 that is away from the first fixing part 111. The fifth side surface 1110-41 is coplanar with the third side surface 1123, that is, the first side surface 1134, the third side surface 1123, and the fifth side surface 1110-41 are coplanar. In this way, the size of the bending-resistant structure 1110 in the first direction X is increased as much as possible within the minimum space between the carrier 30 and the splicing screen 20, thus effectively ensuring bending resistance.

[0340] In some embodiments, as shown in FIG38, the first fixing part 111 has two sets of strip-shaped holes 1111 spaced apart along the width direction (second direction Y). One set of strip-shaped holes 1111 is located between the bearing part 112 and the intermediate anti-bending part 1110-1, and the other set of strip-shaped holes 1111 is located between the intermediate anti-bending part 1110-1 and the fourth limiting part 1110-2. Both sets of strip-shaped holes 1111 include a plurality of strip-shaped holes 1111 spaced apart along the third direction Z, and the length direction of each strip-shaped hole 1111 is parallel to the third direction Z. The hole gaps in the plurality of sets of strip-shaped holes 1111 in the third direction Z do not overlap in the second direction Y. When the splicing screen 20 is in the installation state, as shown in FIG36, the fixing frame 111 can be fixed to the carrier 30 by passing screws 14 through the strip-shaped holes 1111.

[0341] Optionally, the two sets of strip-shaped holes 1111 are evenly and staggered, and the size of each strip-shaped hole 1111 in the two sets of strip-shaped holes 1111 is the same.

[0342] By providing multiple sets of strip-shaped holes 1111 on the first fixing part 111, and ensuring that the gaps between the multiple sets of strip-shaped holes 1111 in the length direction of the first fixing part 111 do not overlap in the width direction of the first fixing part 111, it is ensured that the first fixing part 111 has a fixable position at any position in the length direction. This avoids the fixing of the fixing frame 11 when there are empty areas in the carrier 30. For example, when the mounting surface 31 is the surface of multiple columns, the gap between two adjacent columns constitutes an empty area of ​​the carrier 30. In this case, for the first fixing part 111 with multiple sets of strip-shaped holes 1111, the empty area can be avoided, and the fixing frame 11 can be fixed to multiple columns by holes on the first fixing part 111 corresponding to the area where the columns are located.

[0343] The installation scenarios in this embodiment are applicable to flat walls, curved walls, and surfaces with multiple columns, etc. For specific installation scenarios, please refer to Embodiments 1, 2, and 3 above. Repeated parts will not be repeated.

[0344] In some embodiments, as shown in Figures 39, 40, and 41, the fixing frame 11 further includes a protrusion 118 and a recess 119 disposed opposite each other in the third direction Z; the first fixing part 111 has a first end face 111A and a second end face 111B disposed opposite each other in the third direction Z; in the third direction Z, a portion of the free end of one side of the hollow tube structure protruding from the first end face 111A of the first fixing part 111 is reused as the protrusion 118; in the third direction Z, a portion of the free end of the hollow tube structure recessed into the second end face 111B of the first fixing part 111 is reused as the recess 119. The protrusion 118 includes a first sub-part 1110a, a second sub-part 1110b, a third sub-part 1110c, and a fourth sub-part 1110d protruding from the first end face 111A of the first fixing part 111. The fourth sub-part 1110d is connected to the first end face 111A and disposed opposite to the first sub-part 1110a.

[0345] In this design, the end face of the first fixing part 111 is flush with the end face of the first limiting part 113. A protrusion 118 is connected to the first end face 111A of the first fixing part 111, protruding from the first end face 111A; a recess 119 is recessed into the second end face 111B of the first fixing part 111. During installation, the protrusion 118 of one fixing frame 11 is inserted into the recess 119 of the other fixing frame 11, with a clearance fit, achieving alignment and fixation. This facilitates installation and improves installation efficiency. Simultaneously, the first end face 111A of one fixing frame 11 contacts the second end face 111B of another fixing frame 11, achieving a tight fit.

[0346] In addition, as shown in Figure 39, the fixing frame 11 in this embodiment is also provided with a second slot 1135 for avoiding the bolt 13, and a slide groove 1122 for limiting the movement of the bolt 13 in the third direction Z. For detailed description, please refer to the above embodiment 3. Repeated parts will not be described again.

[0347] In some embodiments, as shown in FIG26, the mounting bracket 10 further includes a bolt 13; the connecting portion 122 has a through threaded hole (not shown in the figure); the first mating portion 123 has a second surface 1232 on the side near the first limiting portion 113; the second surface 1232 has a first slot 1236 extending in a direction perpendicular to the extension of the first mating portion 123, the first slot 1236 exposing the threaded hole on the connecting portion 122; as shown in FIG27, the first limiting portion 113 has a first surface 1132 on the side near the first mating portion 123, the first surface 1132 has a second slot 1135 extending in a direction perpendicular to the extension of the first limiting portion 113; in the installation state of the splicing screen 20, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0348] For example, the extension direction of the first mating part 123 is the length direction of the first mating part 123, as shown by the Z direction in Figure 26; the extension direction of the first limiting part 113 is the length direction of the first limiting part 113, as shown by the Z direction in Figure 27; the direction perpendicular to the extension direction of the first mating part 123 is the height direction of the first mating part 123, as shown by the second direction Y in Figure 26; the direction perpendicular to the extension direction of the first limiting part 113 is the height direction of the first limiting part 113, as shown by the second direction Y in Figure 27; the second direction Y is perpendicular to the bearing surface 1121, or it can be perpendicular to the surface of the connecting part 122 near the bearing surface 1121. The third direction Z is the overall extension direction of the mounting bracket.

[0349] In one specific embodiment, the connecting portion 122 has a threaded hole extending along a second direction Y; the second direction Y is a direction perpendicular to the bearing surface 1121 or a direction perpendicular to the surface of the connecting portion 122 on the side close to the bearing surface 1121; the first mating portion 123 has a first slot 1236 extending along the second direction Y, the first slot 1236 exposing the threaded hole located on the connecting portion 122; the first limiting portion 113 has a second slot 1135 extending along the second direction Y; when the splicing screen 20 is in the installed state, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0350] The threaded hole extends through the entire thickness of the connecting part 122; the threaded hole is located at the end of the connecting part 122 away from the second fixing part 121, so a first slot 1236 is provided on the first mating part 123 to expose the threaded hole, which can prevent the bolt 13 from interfering with the first mating part 123 when tightened.

[0351] Referring to Figure 24, when the splicing screen 20 is in the installation state shown in Figure 24, one end of the bolt 13 is screwed into the threaded hole and passes through the first slot 1236 to abut against the bearing surface 1121.

[0352] With the splicing screen 20 in the installation state shown in Figure 23, one end of the bolt 13 is screwed into the threaded hole and passes continuously through the first slot 1236 and the second slot 1135, abutting against the bearing surface 1121. In this way, when the first limiting part 113 abuts against the first mating part 123, the bolt 13 can be avoided by the second slot 1135, or in other words, the bolt 13 can be accommodated by the second slot 1135, eliminating the influence of the bolt 13 on the reserved space in the first direction X, which is beneficial to reducing the overall size of the mounting bracket 10 installed in the first direction X.

[0353] Bolt 13 is a helical connection within the threaded hole of connecting part 122. As shown in Figures 24 and 28, after the end of bolt 13 abuts against the bearing surface 1121 of bearing part 112, bolt 13 can be tightened further. This allows adjustment of the distance between connecting part 122 and bearing surface 1121 in the second direction Y when connecting part 122 cannot rotate synchronously, thus achieving adjustment of the bracket 12 in the second direction Y. This ensures that all splicing screens 20 are stably in contact with the fixing frame 11, preventing the bracket 12 from being suspended in some areas, and effectively guaranteeing the locking and fixing between multiple splicing screens 20.

[0354] The nut end of the bolt 13 can be a polygonal structure, so that the bolt 13 can be tightened or loosened by a wrench, or the nut end can have a limiting groove (such as a cross or slotted structure), so that the bolt 13 can be tightened or loosened by a corresponding screwdriver.

[0355] As shown in Figure 28, after adjusting the position of the bracket 12 in the second direction Y by continuing to tighten the bolts 13, there is no contact between the first limiting part 113 and the connecting part 122, and between the first mating part 123 and the bearing part 112. At this time, the bracket 12 is supported on the fixed frame 11 only by the end of the bolt 13 abutting against the bearing surface 1121. When adjusting the height of the splicing screen 20 by the bolts 13, one splicing screen 20 can correspond to multiple bolts 13, so that the parallelism of the upper surface of the splicing screen 20 can be ensured when adjusting the height of the splicing screen 20 by using multiple bolts 13 that are spaced apart.

[0356] Optionally, the first slot 1236 extends from the second surface 1232 to the second side 1235 of the first mating portion 123 opposite to the second surface 1232, and / or, the second slot 1135 extends from the first surface 1132 to the first side 1134 of the first limiting portion 113 opposite to the first surface 1132. This ensures sufficient clearance for the bolt 13, preventing interference during installation and improving installation efficiency; it also reduces the weight of the mounting bracket.

[0357] In some embodiments, as shown in FIG27, the first fixing part 111 has multiple sets of strip holes 1111 spaced apart along the width direction (second direction Y); each set of strip holes 1111 includes multiple strip holes 1111 spaced apart along the length direction (i.e., third direction Z) of the first fixing part 111, and the length direction of each strip hole 1111 is parallel to the arrangement direction (i.e., third direction Z) of the multiple strip holes 1111; adjacent sets of strip holes 1111 are staggered in the length direction (i.e., third direction Z) of the first fixing part 111.

[0358] Among them, the strip-shaped holes 1111 are through holes of a certain length, such as oblong holes or rectangular holes. This allows for flexible adjustment of the position of the fixing bolts within the corresponding strip-shaped holes 1111 in the third direction X when the first fixing part 111 is fixed to the mounting surface 31 of the carrier 30, thereby finding an optimal installation position on the carrier 30 and ensuring the installation effect. Furthermore, the multiple strip-shaped holes 1111 also ensure the stability of the fixing frame 11 to the mounting surface 31 of the carrier 30.

[0359] Optionally, the multiple sets of strip-shaped holes 1111 include a first set of strip-shaped holes and a second set of strip-shaped holes, with the first set of strip-shaped holes being closer to the bearing portion 112 than the second set of strip-shaped holes; the first set of strip-shaped holes includes a plurality of first strip-shaped holes 1111a spaced apart along the length direction (third direction Z) of the first fixing portion 111, and the second set of strip-shaped holes includes a plurality of second strip-shaped holes 1111b spaced apart along the length direction (third direction Z) of the first fixing portion 111; the length of the first strip-shaped holes 1111a is greater than the length of the second strip-shaped holes 1111b; every two first strip-shaped holes 1111a in the first set of strip-shaped holes form a group of strip-shaped holes 1111c; the hole gap between two adjacent groups of strip-shaped holes 1111c in the length direction (third direction X) of the first fixing portion 11 corresponds to one second strip-shaped hole 1111b; the hole gap L1 between two first strip-shaped holes 1111a in the group of strip-shaped holes 1111c is smaller than the hole gap L2 between two adjacent groups of strip-shaped holes 1111c.

[0360] In this design, the multiple first strip-shaped holes 1111a within the first group of strip-shaped holes are densely distributed along the third direction Z. This concentrates the installation positions of the fixing frame 11 and the carrier 30 onto the first group of strip-shaped holes. Since the first group of strip-shaped holes is closer to the bearing part 112 than the second group of strip-shaped holes, the structural strength and resistance to bending deformation are stronger at the location near the bearing part 112. Therefore, using the first group of strip-shaped holes to lock and fix the fixing frame 11 ensures installation stability. At the same time, the hole gap L2 between two adjacent strip-shaped hole groups 1111c in the length direction of the first fixing part 11 is greater than the hole gap L1 between two first strip-shaped holes 1111a in the strip-shaped hole group 1111c, ensuring the structural strength in the row direction where the first group of strip-shaped holes is located.

[0361] The gap L2 between two adjacent strip-shaped holes 1111c in the length direction of the first fixing part 11 corresponds to a second strip-shaped hole 1111b, and the projection of the second strip-shaped hole 1111b in the second direction Y covers the projection of the corresponding hole gap in the second direction Y.

[0362] Furthermore, a shorter second strip-shaped hole 1111b is used to fill the installation gap caused by the hole gap between two adjacent strip-shaped hole groups 1111c, ensuring that fixation can be performed precisely at the hole gap position between two adjacent strip-shaped hole groups 1111c, thus avoiding the impact of the fixing frame 11 on the fixation when there is a gap in the carrier 30. For example, in the case where the mounting surface 31 is the surface of multiple columns, the gap between two adjacent columns constitutes a gap in the carrier 30. In this case, for the first fixing part 111 with multiple sets of strip-shaped holes 1111, the gap can be avoided, and the fixing frame 11 can be fixed to multiple columns at the hole positions on the first fixing part 111 corresponding to the area where the columns are located.

[0363] In addition, this disclosure also provides an installation method for a video wall 20, which is used in the mounting bracket 10 described in the above embodiments. As shown in FIG42, the method includes the following steps S110 to S140.

[0364] Step S110: Fix at least one fixing frame 11 on the mounting surface 31 of the carrier 30, the fixing frame 11 forming a first hanging groove 114.

[0365] Step S120: Provide multiple splicing screens 20, at least some of the multiple splicing screens 20 are arranged to form at least one row of splicing screens 20, and at least one row of splicing screens 20 corresponds one-to-one with at least one fixed frame 11.

[0366] Step S130: Fix a bracket 12 to the back of each splicing screen 20 in each row of splicing screens 20. The bracket 12 has a first mating part 123.

[0367] Step S140: Hang the first mating part 123 on the back of each splicing screen 20 in each row onto the first mounting slot 114 of the corresponding fixing frame 11, and lock the multiple splicing screens 20.

[0368] In this embodiment, multiple splicing screens 20 can be mounted on the mounting frame 11 (such as a flat wall, a curved wall, or the surface of multiple columns) of the carrier 30 and the hanging bracket 12 fixed to the back of the splicing screen 20. When locking multiple splicing screens 20, the first mating part 123 can move in the first hanging groove 114 along the direction perpendicular to the mounting surface 31 (first direction X) to achieve adaptive adjustment of multiple splicing screens 20, thereby reducing or even avoiding stress between adjacent splicing screens 20 after locking, thus improving installation efficiency and extending service life.

[0369] In step S110 above, the length of the fixing frame 11 can be designed according to the overall size of a row of splicing screens 20, and the spacing between two adjacent fixing frames 11 can be designed according to the height of a splicing screen 20, so as to ensure that multiple splicing screens 20 can be hung in the first hanging slot 114 on the fixing frame 11 based on the back-fixed bracket 12. Of course, a row of splicing screens 20 can also be achieved by splicing multiple fixing frames 11 to avoid problems such as the fixing frame 11 being too long and difficult to transport.

[0370] When fixing the fixing frame 11 on the mounting surface 31 of the carrier 30, as described above, the fixing frame 11 can be an integral structure or a structure composed of multiple components. If the fixing frame 11 is an integral structure, multiple fixing frames 11 spaced apart along the height direction can be directly fixed on the mounting surface 31 of the carrier 30. If the fixing frame 11 includes a main frame 117 and a bridging frame 116, for each fixing frame 11, multiple main frames 117 can be fixed at horizontal intervals on the mounting surface 31 of the carrier 30, with each main frame 117 having a second hook groove 1172. The hook portion 1162 of the bridging frame 116 is hooked into the second hook groove 1172 and connected to the multiple main frames 117 for limiting. The bridging frame 116 forms a first hook groove 114.

[0371] The number of body frames 117 included in each fixed frame 11 can be set according to specific circumstances. For example, each fixed frame 11 includes multiple body frames 117 corresponding to multiple columns. The bridging frame 116 has multiple hook portions 1162 corresponding to multiple body frames 117. After the multiple hook portions 1162 are respectively hooked onto the second hooking slots 1172 on the corresponding body frames 117, the stability of the bridging frame 116 is ensured. Then, the bridging frame 116 is limited on multiple body frames 117 (refer to the above embodiment for details) to complete the fixing of each fixed frame 11 on the mounting surface 31 of the carrier 30.

[0372] Furthermore, steps S110 and 130 can be executed sequentially or simultaneously. For example, step S110 can be executed first, followed by step S130 after step 120 is completed, or step S110 can be executed after steps S120 and 130 are completed.

[0373] In step S140 above, when hanging the splicing screen 20 on each fixed frame 11, multiple splicing screens 20 in each row can be hung one by one on a corresponding fixed frame 11 and locked in place. Alternatively, multiple splicing screens 20 in each row can be locked in place beforehand and then hung on a fixed frame 11 all at once. This embodiment does not limit the specific method described herein.

[0374] In light of the aforementioned mounting bracket 10 also including bolts 13, the mounting of each row of splicing screens 20 on the fixing frame 11 can be achieved by: attaching the first mating part 123 on the back of each splicing screen 20 to the first mounting groove 114 of the fixing frame 11; passing the bolts 13 through the threaded holes on the connecting part 122 of the bracket 12, and adjusting the tightness of the bolts 13 in the threaded holes to ensure that the multiple splicing screens 20 in each row are at the same height; and then fixing the multiple splicing screens 20 in each row to each other, thereby completing the installation of the splicing screens 20 on the mounting surface 31 of the carrier 30.

[0375] Alternatively, for the mounting bracket 10 of embodiment 1 or 2, the first mating part 123 on the back of each splicing screen 20 is hooked into the first hooking groove 114 of the fixing frame 11; the bolt 13 is passed through the threaded hole on the connecting part 122 of the bracket 12, and the tightness of the bolt 13 in the threaded hole is adjusted to ensure that the connecting part 122 is in contact with the first bending part 1131 and the bearing part 112 is in contact with the second bending part 1231, thereby achieving close contact between the bracket 12 and the fixing frame 11, ensuring that while locking and fixing, multiple splicing screens 20 in the same row are at the same height.

[0376] Alternatively, for the mounting bracket 10 of embodiment 3 or 4, the first mating part 123 on the back of each splicing screen 20 is hung in the first hanging groove 114 of the fixing frame 11; the bolt 13 is passed through the threaded hole on the connecting part 122 included in the bracket 12, and the tightness of the bolt 13 in the threaded hole is adjusted to ensure that the connecting part 122 is in contact with the first limiting part 113 and the bearing part 112 is in contact with the first mating part 123, thereby achieving close contact between the bracket 12 and the fixing frame 11, ensuring that while locking and fixing, multiple splicing screens 20 in the same row are at the same height.

[0377] In conjunction with the aforementioned mounting bracket 10, the fixing bracket 11 also includes a protrusion and a recess disposed opposite each other in the third direction Z. For fixing at least one fixing bracket 11 on the mounting surface 31 of the carrier 30, for multiple fixing brackets 11 in a row, the protrusion 118 of one fixing bracket 11 is inserted into the recess 119 of another adjacent fixing bracket 11 and fixed on the mounting surface 31 of the carrier 30; wherein the protrusion 118 and the recess 119 are clearance-fitted.

[0378] This disclosure also provides a display device, which includes at least one mounting bracket 10 and a plurality of splicing screens 20. The plurality of splicing screens 20 are locked together, and at least a portion of the plurality of splicing screens 20 are arranged to form at least one row of splicing screens 20. At least one mounting bracket 10 corresponds one-to-one with at least one row of splicing screens 20. At least one mounting bracket 10 is used to connect to the mounting surface 31 of the carrier 30. The plurality of splicing screens 20 included in each row of splicing screens 20 are respectively fixedly connected to the plurality of brackets 12 included in a corresponding mounting bracket 10.

[0379] Thus, for multiple splicing screens that are mounted on the mounting surface 31 of the carrier by mounting brackets and locked together, the hanger 12 can move in the first mounting groove 114 along the direction of the vertical mounting surface 31 based on the interaction force of the multiple splicing screens when locked, thereby realizing the adaptive adjustment of the multiple splicing screens 20 in the direction of the vertical mounting surface 31, so as to reduce or even avoid the interaction force between adjacent splicing screens 20 in the direction of the vertical mounting surface 31, and facilitate the extension of the service life of the display device.

[0380] Each splicing screen 20 includes one or more display substrates, which are Mini-LED or Micro-LED display substrates. For Mini-LED display substrates, there are, but are not limited to, Chip On Board (COB) substrates, Chip On Glass (COG) substrates, and Surface Mount Device (SMD) substrates.

[0381] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
