[0089] Figure 1 The structural schematic diagram of a display screen provided by an embodiment of the present disclosure is exemplified. Figure 2 The side view structural schematic diagram of a display screen provided by an embodiment of the present disclosure is exemplified. Figure 3 The structural schematic diagram of a mounting bracket 10 provided by an embodiment of the present disclosure is exemplified. As Figure 1 、 Figure 2 and Figure 3As shown, the mounting bracket 10 includes: a fixing frame 11 and a hanging frame 12, the fixing frame 11 includes a first fixing portion 111, a bearing portion 112 and a first limiting portion 113, the first fixing portion 111 has a first fitting surface 1112, the first fitting surface 1112 is used to fit the mounting surface 31 of the carrier 30, and the first fixing portion 111 is used to connect the mounting surface 31 of the carrier 30, the bearing portion 112 is connected to the side of the first fixing portion 111 away from the first fitting surface 1112, and is formed with a bearing surface 1121, and the first limiting portion 113 is connected to the bearing surface 1121; the hanging frame 12 includes a second fixing portion 121, a connecting portion 122 and a first matching portion 123, the second fixing portion 111 21 has a second fitting surface 1211, the second fitting surface 1211 is used to fit the back of the splicing screen 20, and the second fixing portion 121 is used to connect the back of the splicing screen 20, the connecting portion 122 is connected to the side of the second fixing portion 121 away from the second fitting surface 1211, the first matching portion 123 is connected to the connecting portion 122, and cooperates with the first limiting portion 113, the first matching portion 123 is used to limit the splicing screen 20 in the first hanging groove 114 when the splicing screen 20 is in the installed state, the first hanging groove 114 is surrounded by the first limiting portion 113, the bearing surface 1121 and the first fixing portion 111, or surrounded by the first limiting portion 113, the bearing surface 1121 and the installation surface 31.

[0090] In the embodiment of the present disclosure, the splicing screen 20 is fixed on the mounting surface 31 of the carrier 30 by the fixing frame 11 and the hanging frame 12 included in the mounting bracket 10, thereby simplifying the installation of the splicing screen 20 and facilitating improving the installation efficiency; and when the splicing screen 20 is in the installed state, the first matching portion 123 of the hanging frame 12 is limited in the first hanging groove 114 surrounded by the first limiting portion 113 and the bearing surface 1121, and the first fixing portion 111 or the mounting surface 31. At this time, based on the locking of multiple splicing screens 20, the first matching portion 123 can be moved in the first hanging groove 114, thereby realizing the adaptive adjustment of the splicing screen 20 in the direction perpendicular to the mounting surface 31, so as to reduce or even avoid the force acting on the splicing screen 20 in the direction perpendicular to the mounting surface 31, so as to extend the service life.

[0091] In some embodiments, Figure 3 As shown, the first fixing portion 111 is used to be connected to the installation 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 portion 112 facing away from the ground, so that the first limiting portion 113 is located on the side of the bearing portion 112 facing away from the ground; when the splicing screen 20 is in the installed state, the first matching portion 123 is connected to the surface of the connecting portion 122 facing the ground.

[0092] Optionally, the mounting surface 31 connecting the first fixing portion 111 forms a first included angle θ1 with the horizontal plane, where θ1 is greater than or equal to 80 degrees and less than or equal to 100 degrees. For example, the first included angle θ1 formed by 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 included angle θ1 formed by the mounting surface 31 and the horizontal plane is 90 degrees.

[0093] In addition, the mounting surface 31 is not a strictly flat surface, but has certain protrusions and / or depressions. After multiple splicing screens 20 are locked to each other, the flatness of the multiple splicing screens 20 can be ensured by the movement of the hanging bracket 12 in the first hanging slot 114 along the direction perpendicular to the mounting surface 31, while avoiding the situation where stress is borne between two splicing screens 20 that are locked to each other, thereby extending the service life of the splicing screens 20.

[0094] Specifically, when the splicing screen 20 is hung in the first hanging slot 114 of the fixing frame 11 based on the hanging bracket 12, it can be as Figure 3 shown, based on the depression of the mounting surface 31, the first fitting portion 123 moves to a position in contact with the first limiting portion 113, or it can be as Figure 4 shown, based on the protrusion of the mounting surface 31, there is a certain gap between the first fitting portion 123 and the first limiting portion 113.

[0095] In some embodiments, the width of the first hanging slot 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 facilitates ensuring that the first fitting portion 123 has sufficient movement space in the first hanging slot 114, thereby avoiding the situation where stress is generated between the first fitting portion 123 and the first limiting portion 113 due to the depression of the mounting surface 31, and avoiding the situation where stress is generated between the first fitting portion 123 and the first fixing portion 111 or the mounting surface 31 due to the protrusion of the mounting surface 31.

[0096] For example, the width of the first hanging slot 114 in the direction perpendicular to the fitting surface of the first fixing portion 111 is 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, etc.

[0097] Of course, the width of the first hanging slot 114 in the direction perpendicular to the fitting surface of the first fixing part 111 can also be other values, as long as the movable distance of the first fitting part 123 in the first hanging slot 114 in the direction perpendicular to the mounting surface 31 (i.e., the first fitting surface 1112) is greater than or equal to the flatness of the mounting surface 31, so as to avoid the situation of stress generation between the first fitting part 123 and the first limiting part 113 due to the depression of the mounting surface 31, and to avoid the situation of stress generation between the first fitting part 123 and the first fixing part 111 or the mounting surface 31 due to the protrusion of the mounting surface 31; or the movable distance of the first fitting part 123 limited in the first hanging slot 114 is slightly less than the flatness of the mounting surface 31, so as to avoid the situation of large stress generation between the first fitting part 123 and the first limiting part 113 due to the depression of the mounting surface 31, and to avoid the situation of large stress generation between the first fitting part 123 and the first fixing part 111 or the mounting surface 31 due to the protrusion of the mounting surface 31.

[0098] In some embodiments, as Figure 5 shown, the first limiting part 113 has a first surface 1132 located on the side close to the first fitting part 123. The first surface 1132 forms a second included angle θ2 with the bearing surface 1121 and in the direction close to the first fixing part 111, and the second included angle θ2 is an obtuse angle; the first fitting part 123 has a second surface 1232 on the side close to the first limiting part 113. The second surface 1232 forms a third included angle θ3 with the surface of the connecting part 122 on the side facing the first limiting part 113 and in the direction close to the second fixing part 121, and the third included angle θ3 is an obtuse angle.

[0099] In this way, by setting the inclination of the first surface 1132 and the second surface 1232, it is convenient to realize the guiding of the first limiting part 113 to the first fitting part 123, so as to facilitate the hanging of the hanging frame 12 in the first hanging slot 114 and improve the installation efficiency of the splicing screen 20; in addition, when the first surface 1132 contacts the second surface 1232, the first limiting part 113 can support the first fitting part 123, thereby further improving the hanging stability of the hanging frame 12 on the fixing frame 11.

[0100] Optionally, the degrees of the second included angle θ2 and the third included angle θ3 are equal, so as to be in surface contact when the first surface 1132 contacts the second surface 1232, thereby increasing the supporting area of the first limiting part 113 for the first fitting part 123.

[0101] Exemplarily, 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. For example, the second included angle θ2 and the third included angle θ3 are both 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, etc.

[0102] Among them, between the first surface 1132 of the first limiting portion 113 close to the first mating portion 123 and the bearing surface 1121 of the bearing portion 112, and between the second surface 1132 of the first mating portion 123 close to the first limiting portion 113 and the side surface of the connecting portion 122 facing the first limiting portion 113, arc transitions can be provided to avoid stress concentration between the first limiting portion 113 and the bearing portion 112, and between the first mating portion 123 and the connecting portion 122. Of course, ribs can also be provided between the side surface of the first limiting portion 113 facing away from the first fixing portion 111 and the bearing portion 112, and between the side surface of the first mating portion 123 facing away from the second fixing portion 121 and the connecting portion 122, respectively, to strengthen the connection strength between the first limiting portion 113 and the bearing portion 112, and between the first mating portion 123 and the connecting portion 122, and at the same time realize the support for the first limiting portion 113 and the first mating portion 123, so as to avoid breakage between the first limiting portion 113 and the bearing portion 112, and between the first mating portion 123 and the connecting portion 122.

[0103] In some embodiments, such as Figure 3 , Figure 4 or Figure 6 shown, the free end of the first limiting portion 113 has a first bending portion 1131 facing away from the first fixing portion 111, the free end of the first mating portion 123 has a second bending portion 1231 facing away from the second fixing portion 121, and the distance from the first bending portion 1131 to the bearing portion 112 is equal to the distance from the second bending portion 1231 to the connecting portion 122.

[0104] In this way, through the setting of the first bending portion 1131 and the second bending portion 1231, and the distance from the first bending portion 1131 to the bearing portion 112 being equal to the distance from the second bending portion 1231 to the connecting portion 122, it is ensured that when the free end of the first mating portion 123 contacts the bearing surface 1121 of the bearing portion 112, the first bending portion 1131 abuts against the connecting portion 122, and at the same time the second bending portion 1231 abuts against the bearing surface 1121, thereby increasing the support area of the hanging bracket 12 on the fixing bracket 11, so as to facilitate improving the stability of the support of the fixing bracket 11 for the hanging bracket 12, that is, ensuring the stability of the installation of the splicing screen 20 on the installation surface 31 of the carrier 30.

[0105] Among them, the first bending portion 1131 faces away from the first fixing portion 111, that is, the distance between the edge of the first bending portion 1131 away from the first limiting portion 113 and the first fixing portion 111 is greater than the distance between the free end of the first limiting portion 113 and the first fixing portion 111; the second bending portion 1231 faces away from the second fixing portion 121, that is, the distance between the edge of the second bending portion 1231 away from the first engaging portion 123 and the second fixing portion 121 is greater than the distance between the free end of the first engaging portion 123 and the second fixing portion 121. In addition, due to the arrangement of the second bending portion 1231, the movable space of the first engaging portion 123 in the first hanging groove 114 along the direction perpendicular to the first fitting surface 1112 will inevitably be reduced. Thus, when designing the fixing frame 11, the first hanging groove 114 can be set to have a greater width in the direction perpendicular to the first fitting surface 1112 to ensure the adaptive adjustment of the hanging frame 12 in the first hanging groove 114 when the splicing screen 20 is installed.

[0106] In some embodiments, as Figure 7 and Figure 8 shown, the mounting bracket 10 further includes a bolt 13; the connecting portion 122 has a threaded hole (not shown in the figure), and the threaded hole is located on the side of the first engaging portion 123 away from the second fixing portion 121. 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.

[0107] Among them, the threaded hole is located on the side of the first engaging portion 123 away from the second fixing portion 121, that is, the distance from the threaded hole to the second fixing portion 121 is greater than the distance from the free end of the first engaging portion 123 to the second fixing portion; the bolt 13 is screwed into the threaded hole of the connecting portion 122. Thus, as Figure 8 and Figure 9 shown, after the end of the bolt 13 abuts against the bearing surface 1121 of the bearing portion 112, the bolt 13 can be further tightened. Thus, when the connecting portion 122 cannot rotate synchronously, the distance between the connecting portion 122 and the bearing surface 1121 in the length direction of the bolt 13 can be adjusted to realize the adjustment of the hanging frame 12 in the height direction, so as to effectively ensure the locking and fixing between multiple splicing screens 20.

[0108] Among them, the nut end of the bolt 13 can be a polygonal structure to realize the tightening or loosening of the bolt 13 through a wrench, or the nut end has a limiting groove (such as a cross or a single - character structure, etc.) to realize the tightening or loosening of the bolt 13 through a corresponding screwdriver.

[0109] Among them, as Figure 9As shown, after continuing to tighten the bolt 13 to adjust the position of the hanging bracket 12 in the height direction, there is no contact between the first limiting portion 113 and the connecting portion 122, and between the first mating portion 123 and the bearing portion 112. At this time, the hanging bracket 12 is supported on the fixing bracket 11 only by the end of the bolt 13 abutting against the bearing surface 1121.

[0110] Among them, when adjusting the height of the splicing screen 20 through the bolt 13, one splicing screen 20 can correspond to multiple bolts 13, so as to ensure the parallelism of the upper surface of the splicing screen 20 when adjusting the height of the splicing screen 20 through the multiple bolts 13 distributed at intervals.

[0111] Combined with the above, the free end of the first mating portion 123 has a second bending portion 1231. At this time, as Figure 10 and Figure 11 shown, the second bending portion 1231 has an avoidance groove 1233 (away from the edge of the first mating portion 123), so that the bolt 13 can pass through the avoidance groove 1233 and abut against the bearing surface 1121 of the bearing portion 112, so as to avoid interference between the second bending portion 1231 and the bolt 13.

[0112] In some embodiments, as Figure 10 and Figure 11 shown, the bearing portion 112 has a sliding groove 1122 located on the bearing surface 1121; the sliding groove 1122 is located on one side of the first limiting portion 113 close to the first fixing portion 111, and the length direction of the sliding groove 1122 is parallel to the plane perpendicular to the first fitting surface 1112 and the horizontal plane. When the splicing screen 20 is in the installed state, one end of the bolt 13 abutting against the bearing surface 1121 is limited in the sliding groove 1122.

[0113] In this way, by providing the sliding groove 1122 on the bearing surface 1121 of the bearing portion 112 and limiting one end of the bolt 13 in the sliding groove 1122, the movement of the bolt 13 in the direction close to the first limiting portion 113 or away from the first limiting portion 113 is ensured, and at the same time, the movement of the bolt 13 in the width direction of the sliding groove 1122 is limited, that is, the adaptive adjustment of the splicing screen 20 in the direction perpendicular to the fitting surface with the first fixing portion 111 is ensured, and at the same time, the movement of the splicing screen 20 in the horizontal direction parallel to the fitting surface with the first fixing portion 111 is avoided, so as to ensure the stability of the splicing screen 20 installed on the mounting bracket 10.

[0114] Wherein, when the bearing surface 1121 on the bearing part 112 is perpendicular to the first fitting surface 1112, the length direction of the sliding groove 1122 is perpendicular to the first fitting surface 1112; one end of the sliding groove 1122 in the length direction extends to the edge of the bearing surface 1121 close to the first fixing part 111, and the other end extends to the corner where the first limiting part 113 is connected to the bearing surface 1121, so as to ensure the sliding space of the bolt 13 in the sliding groove 1122, and further ensure the adaptive adjustment of the splicing screen 20 in the first hanging groove 114.

[0115] Of course, the length of the sliding 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 sliding groove 1122 does not need to extend to the edge of the bearing surface 1121 close to the first fixing part 111, and since the first matching part 123 occupies space in the first hanging groove 114, the other end of the sliding groove 1122 does not need to extend to the corner where the first limiting part 113 is connected to the bearing surface 1121. In this way, the adaptive adjustment of the splicing screen 20 in the first hanging groove 114 is ensured, and at the same time, it is convenient to ensure the structural strength of the bearing part 112.

[0116] In addition, for the case where one splicing screen 20 corresponds to multiple bolts 13 described above, the bearing surface 1121 of the bearing part 112 may only have a sliding groove 1122 for limiting one bolt 13, or the bearing surface 1121 may have sliding grooves 1122 for respectively limiting each bolt 13. By way of example, one splicing screen 20 corresponds to two bolts 13, and the bearing surface 1121 of the bearing part 112 only has a sliding groove 1122 for limiting one bolt 13.

[0117] In some embodiments, as Figure 3 shown, the mounting surface 31 connecting the first fixing part 111 forms a first included angle θ1 with the horizontal plane, and a fourth included angle θ4 is formed between the extension surface of the first fitting surface 1112 (i.e., the mounting surface 31) and the bearing surface 1121, and the degrees of the first included angle θ1 and the fourth included angle θ4 are equal.

[0118] In this way, it is convenient to ensure that after the first fitting surface 1112 of the first fixing part 111 is fitted 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, so as to facilitate the stable support of the bearing surface 1121 for the hanging bracket 12, and at the same time ensure the stable suspension of the splicing screen 20 on the fixing frame 11, and avoid the tendency of the hanging bracket 12 to move in the direction perpendicular to the first fitting surface 1112 when the hanging bracket 12 is hung on the fixing frame 11, that is, to avoid the tendency of the splicing screen 20 to move in the direction perpendicular to the first fitting surface 1112, so as to further avoid the mutual force between adjacent splicing screens 20.

[0119] In some embodiments, the included angle between the extension surface of the second fitting surface 1211 (i.e., the back surface 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 included angle between the extension surface of the first fitting surface 1112 (i.e., the mounting surface 31) and the bearing surface is 90 degrees.

[0120] Wherein, the first included 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 plane. In this way, after the splicing screen 20 is hung on the fixing frame 11 through the hanging bracket 12, it is convenient to ensure that the display surface of the splicing screen 20 is a vertical plane, and further ensure the display effect after the splicing screen 20 is installed.

[0121] In some embodiments, as Figure 12 shown, the hanging bracket 12 further includes a first reinforcing portion 124 integrally formed with the second fixing portion 121; the first reinforcing portion 124 is disposed opposite to the connecting portion 122 and is located on the side of the connecting portion 122 away from the first engaging portion 123.

[0122] Wherein, the two side edges of the second fixing portion 121 are respectively connected to the connecting portion 122 and the first reinforcing portion 124 (such as integrally formed), so as to form a structure with a U-shaped end face. In this way, the structure of the hanging bracket 12 is equivalent to the structure of a channel steel, thereby effectively ensuring the structural strength of the hanging bracket 12, and further ensuring the stability of the splicing screen 20 installed on the mounting bracket 10.

[0123] In some embodiments, as Figure 13 shown, the hanging bracket 12 is a strip-shaped structure, and one hanging bracket 12 is used for fixedly connecting with one splicing screen 20, that is, one splicing screen 20 corresponds to one hanging bracket 12.

[0124] Wherein, the strip-shaped hanging bracket 12 has a certain length, and the length of the hanging bracket 12 is equal to or slightly less than the width of one splicing screen 20, so as to ensure that one hanging bracket 12 can realize the installation of one splicing screen 20; in addition, setting the hanging bracket 12 as a strip-shaped structure is convenient for leveling the hanging bracket 12 when the second fixing portion 121 of the hanging bracket 12 is fixedly connected to the back surface of the splicing screen 20, that is, it is convenient to ensure that the length direction of the hanging bracket 12 is parallel to the upper side surface of the splicing screen 20, and at the same time, it is convenient to simplify the fixed installation of the hanging bracket 12 on the back surface of the splicing screen 20.

[0125] In other embodiments, as Figure 14 shown, the hanging bracket 12 is a block-shaped structure, and a plurality of hanging brackets 12 are used for fixedly connecting with the same splicing screen 20, that is, one splicing screen 20 corresponds to a plurality of hanging brackets 12.

[0126] Among them, the hanger 12 is a block structure, that is, the length of the hanger 12 is short, and multiple hangers 12 are required to install a splicing screen 20; in addition, setting the hanger 12 as a block structure is convenient for saving the material of the hanger 12, achieving the effect of cost saving, and at the same time facilitating the lightweight setting of the hanger 12 to reduce the weight borne on the fixing frame 11 and ensure the stability of the fixing of the fixing frame 11 to the mounting surface 31 of the carrier 30.

[0127] In the embodiments of the present disclosure, for the specific structure of the hanger 12, the second fixing portion 121, the connecting portion 122, and the first matching portion 123 may be integrally formed structures. For the specific structure of the fixing frame 11, the first fixing portion 111, the bearing portion 112, and the first limiting portion 113 may be integrally formed structures, or the bearing portion 112 and the first limiting portion 113 may be integrally formed structures and are limitedly connected to the first fixing portion 111.

[0128] In some embodiments, such as Figure 15 or Figure 16 As shown, the fixing frame 11 is a strip structure, and the first fixing portion 111, the bearing portion 112, and the first limiting portion 113 are integral structures.

[0129] Among them, 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) to ensure that multiple splicing screens 20 can be installed through one fixing frame 11, so as to facilitate ensuring that multiple splicing screens 20 are fixed at the same height. In addition, for the case where the length of one fixing frame 11 is short, in order to ensure that a row of splicing screens 20 is at the same height, adjacent two fixing frames 11 can be docked through the insertion interface to ensure that multiple fixing frames 11 corresponding to a row of splicing screens 20 are at the same height, that is, multiple fixing frames 11 are on the same straight line.

[0130] Among them, by setting the first fixing portion 111, the bearing portion 112, and the first limiting portion 113 as integral structures, it is convenient to enhance the structural strength of the fixing frame 11. At the same time, setting the fixing frame 11 as a strip structure is convenient for hanging the hanger 12 at any position of the fixing frame 11, and thus it is convenient to hang the splicing screen 20 at any position of the fixing frame 11.

[0131] Among them, the bearing part 112 is connected to the side of the first fixing part 111 away from the fitting surface. The connection between the surface of the bearing part 112 away from the bearing surface 1121 and the first fixing part 111 is in an arc transition, so as to avoid stress concentration at the connection between the bearing part 112 and the first fixing part 111. Of course, a reinforcing rib connecting the bearing part 112 and the first fixing part 111 can also be provided on the side of the bearing part 112 away from the bearing surface 1121 to ensure the connection strength between the bearing part 112 and the first fixing part 111, so as to ensure the supporting force of the bearing part 112 on the hanger 12 to which the splicing screen 20 is fixed.

[0132] In some embodiments, as Figure 15 shown, the first fixing part 111 has a plurality of strip-shaped holes 1111 distributed at intervals 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.

[0133] Among them, the strip-shaped hole 1111 is a through hole with a certain length, such as an oblong hole, a rectangular hole, etc. Thus, through the arrangement of the plurality of strip-shaped holes 1111, when the first fixing part 111 is fixed to the mounting surface 31 of the carrier 30, the position of each fixing bolt in the corresponding strip-shaped hole 1111 can be adjusted, so as to ensure the stability of the fixation of the fixing frame 11 to the mounting surface 31 of the carrier 30.

[0134] In other embodiments, as Figure 16 shown, the first fixing part 111 has multiple groups of strip-shaped holes 1111 distributed at intervals along the width direction ( Figure 16 two groups of strip-shaped holes 1111 are shown in

[0135] ); each group of strip-shaped holes 1111 includes a plurality of strip-shaped holes 1111 distributed at intervals along the length direction of the first fixing part 111, and the length direction of each strip-shaped hole 1111 is parallel to the arrangement direction of the plurality of strip-shaped holes 1111; the hole gaps of the multiple groups of strip-shaped holes 1111 in the length direction of the first fixing part 111 do not have an overlapping area in the width direction of the first fixing part 111. Among them, by providing multiple groups of strip-shaped holes 1111 on the first fixing part 111 and ensuring that the gaps of the multiple groups 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 any position of the first fixing part 111 in the length direction has a fixable position, so as to avoid affecting the fixation of the fixing frame 11 when there is a vacant area in the carrier 30. For example, in the case where the mounting surface 31 described above is the surface of multiple columns, the gap between adjacent two columns constitutes the vacant area of the carrier 30. At this time, for the first fixing part 111 with multiple groups of strip-shaped holes 1111, the vacant area can be avoided to realize the fixation of the fixing frame 11 to the multiple columns at the hole positions corresponding to the column areas on the first fixing part 111.

[0136] In some embodiments, Figure 1 As shown, the first fixing portion 111 is used to connect to the surface of the carrier 30 which is a wall (installation surface 31 ).

[0137] Of course, in combination with the above-mentioned situation that the first fixing portion 111 has a plurality of strip-shaped holes 1111, the first fixing portion 111 can also be connected to the surface of the carrier 30 which is a column. Figure 17 As shown, the spliced screen 20 is installed on the surface of a plurality of columns (carriers 30 ) through the mounting bracket 10 .

[0138] In some embodiments, Figure 15 or Figure 16 As shown, the fixing frame 11 further includes a second reinforcing portion 115 integrally formed with the first fixing portion 111 ; the second reinforcing portion 115 is disposed opposite to the bearing portion 112 and is located at a side of the bearing portion 112 away from the first limiting portion 113 .

[0139] The two sides of the first fixing portion 111 are respectively connected to the bearing portion 112 and the second reinforcing portion 115 (for example, integrally formed) to form a structure with a U-shaped end face. In this way, the structure of the fixing frame 11 is equivalent to the structure of the channel steel, thereby effectively ensuring the structural strength of the fixing frame 11, and further ensuring the stability of the spliced screen 20 when it is hung on the fixing frame 11.

[0140] In some embodiments, the first fixing portion 111 and the bearing portion 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 portion 113 and the bearing surface 1121 and the mounting surface 31 form a first hanging groove 114.

[0141] Among them, the first fixing part 111 and the bearing part 112 are connected to form a structure with an L-shaped end face, and 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, the nut of the fixing bolt for locking the first fixing part 111 can be avoided from being located in the first hanging groove 114, which affects the movable distance of the first matching part 123 in the first hanging groove 114, thereby ensuring the adaptive adjustment function of the splicing screen 20 in the direction of the fitting surface perpendicular to the first fixing part 111.

[0142] In some other embodiments, the first fixing portion 111 and the bearing portion 112 are connected to form a T-shaped structure at the end surface, and the first limiting portion 113 , the bearing surface 1121 , and the first fixing portion 111 form a first hanging groove 114 .

[0143] Among them, the first fixing part 111 is connected to the bearing part 112 to form a structure with a T-shaped end face, and the first fixing part 111 can be fixed on the mounting surface 31 of the carrier 30 on both sides of the bearing part 112 to ensure the tight connection between the first fixing part 111 and the carrier 30. In addition, for the fixing holes on the first fixing part 111 located on the side of the bearing part 112 close to the first limiting part 113, countersunk holes can be provided. After the first fixing part 111 is fixed by the fixing bolts, the nuts of the fixing bolts can be prevented from protruding from the surface of the first fixing part 111, which affects the movable distance of the first engaging part 123 in the first hanging groove 114, thereby ensuring the adaptive adjustment function of the splicing screen 20 in the direction perpendicular to the joint surface of the first fixing part 111.

[0144] In some embodiments, such as Figure 18 , Figure 19 and Figure 20 shown, the fixing frame 11 includes a bridging frame 116 and a plurality of body frames 117; the bridging frame 116 is a strip-shaped structure, and the plurality of body frames 117 are spaced apart along the length direction 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 is connected to the first fixing part 111, and in the state where the splicing screen 20 is installed and completed, the second limiting part 1171 encloses a second hanging groove 1172 with the notch facing away from the ground on the side close to the first fixing part 111; the bridging frame 116 includes a supporting part 1161, a hook part 1162, a bearing part 112 and a first limiting part 113, the supporting part 1161 is connected to the surface of the bearing part 112 facing away from the first limiting part 113, and the hook part 1162 is connected to the side of the bearing part 112 facing away from the bearing surface 1121; in the state where the splicing screen 20 is installed and completed, the supporting part 1161 is in limit connection with the first fixing part 111, and the hook part 1162 is limited in the second hanging groove 1172.

[0145] In this way, the fixing frame 11 is provided with a plurality of body frames 117 to connect with the mounting surface 31 of the carrier 30 through the plurality of body frames 117, ensuring that the mounting bracket 10 can be applied to more installation scenarios, such as the surfaces of the above-mentioned walls, the surfaces of multiple columns, etc.; then, the connection between the bridging frame 116 and the plurality of body frames 117, so that through the first hanging groove 114 formed by the first limiting part 113 on the strip-shaped bridging frame 116, the hanging positions of a plurality of hanging frames 12 are provided, and thus it is convenient to realize the installation of a plurality of splicing screens 20 on the mounting bracket 10.

[0146] Among them, the bridging frame 116 in a strip structure has a certain length, and the length of the bridging frame 116 is greater than or equal to the sum of the widths of multiple splicing screens 20 (such as the sum of the widths of 3, 5, 8, etc. splicing screens 20), so as to ensure that the installation of multiple splicing screens 20 can be realized through one bridging frame 116, thereby facilitating the fixation of multiple splicing screens 20 at the same height; in addition, the supporting part 1161 is connected to the surface of the bearing part 112 facing away from the first limiting part 113, and can be an integral structure with the bearing part 112, thus avoiding the interference between the supporting part 1161 and the hanging bracket 12, while ensuring the supporting strength of the supporting part 1161 for the bearing part 112, avoiding the disconnection of the connection between the supporting part 1161 and the bearing part 112, and at the same time simplifying the structure of the installation bracket 10 and improving the installation efficiency of the splicing screen 20.

[0147] Among them, the supporting part 1161 and the first fixing part 111 can be directly fixedly connected, that is, the supporting part 1161 can be directly locked on the first fixing part 111 through fixing bolts to realize the limitation of the supporting part 1161 on the first fixing part 111. Of course, the supporting part 1161 can also be limited on the first fixing part 111 in other ways, which will be described in detail below.

[0148] In some embodiments, as Figure 19 or Figure 20 shown, the body frame 117 further includes a third limiting part 1173; the third limiting part 1173 is connected to and oppositely arranged with 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 supporting part 1161 on the first fixing part 111.

[0149] Among them, the third limiting part 1173 has an installation hole at a position facing the supporting part 1161, so that when one end of the fixing bolt is screwed into the installation hole, it can abut against the supporting part 1161. Furthermore, when the fixing bolt is tightened on the third limiting part 1173, the supporting part 1161 can be clamped between the end of the fixing bolt and the first fixing part 111, thereby realizing the limitation of the supporting part 1161 on the first fixing part 111.

[0150] Among them, the main body frame 117 further includes a connecting member 1174. The connecting member 1174 connects the first fixing portion 111 and the third limiting portion 1173, so that the first fixing portion 111, the connecting member 1174, and the third limiting portion 1173 are connected into a structure with a U-shaped end face, thereby ensuring that the third limiting portion 1173 is relatively arranged while being connected to the first fixing portion 111. The first fixing portion 111, the connecting member 1174, and the third limiting portion 1173 may be an integral structure to ensure the structural strength of the main body frame 117. In addition, when the main body frame 117 includes the connecting member 1174, the supporting portion 1161 can be supported on the connecting member 1174 and limited on the first fixing portion 111 to ensure the reliability of the limiting of the supporting portion 1161 on the first fixing portion 111.

[0151] In some other embodiments, as Figure 21 shown, the surface of the first fixing portion 111 facing away from the first fitting surface 1112 has a convex column 1175. The main body frame 117 further includes a locking portion 1176 connected to the middle of the convex column 1175 and arranged opposite to the first fixing portion 111. When the splicing screen 20 is in the installed state, the fixing bolt is fixedly connected to the locking portion 1176, and the supporting portion 1161 is clamped between the end of the convex column 1175 and the nut of the fixing bolt.

[0152] Among them, the locking portion 1176 has a mounting hole at a position facing the supporting portion 1161. Thus, when one end of the fixing bolt is screwed into the mounting hole, it can abut against the supporting portion 1161. Further, when the fixing bolt is tightened on the locking portion 1176, the supporting portion 1161 can be clamped between the nut of the fixing bolt and the end of the convex column 1175, thereby realizing the limiting of the supporting portion 1161 on the first fixing portion 111.

[0153] Among them, the locking portion 1176 is connected to the middle of the convex column 1175, so that there is still enough screwing distance after the fixing bolt is screwed into the mounting hole on the locking portion 1176, thereby ensuring that when the fixing bolt is tightened on the locking portion 1176, the nut of the fixing bolt can abut against the supporting portion 1161.

[0154] Optionally, the locking portion 1176 can be connected to the side of the convex column 1175 facing away from the bearing portion 112, so that when the supporting portion 1161 is limited on the first fixing portion 111, the supporting of the supporting portion 1161 can be realized through the threaded section of the fixing bolt, thereby ensuring the stability of the limiting of the supporting portion 1161 on the first fixing portion 111.

[0155] Optionally, a contact gasket is sleeved on the fixing bolt, and the contact gasket is located between the supporting portion 1161 and the nut of the fixing bolt. In this way, through the contact gasket sleeved on the fixing bolt, it is convenient to increase the clamping area of the supporting portion 1161, thereby ensuring the stability of the limiting of the supporting portion 1161.
