Description

Technical Field

[0001] This invention relates to the field of display screen installation technology, and in particular to a display screen mounting frame and display device. Background Technology

[0002] LED displays are widely used in concerts, exhibitions, sporting events, and theater stages due to their advantages such as vibrant colors, wide dynamic range, high brightness, long lifespan, and stable and reliable operation. To meet the needs of different scenarios, users often need to splice multiple displays to form larger or specially shaped display devices.

[0003] Traditional LED display splicing methods mainly include flat splicing and curved splicing, achieving the connection between multiple screens by setting connectors or quick locks at the edges of the screens. With the diversification of application scenarios, display structures that can only splice flat or curved surfaces can no longer meet practical needs. For example, in exhibition displays and commercial facades, it is often necessary to splice displays into three-dimensional shapes with right angles to enhance 3D visual effects or achieve continuous image display at corners.

[0004] However, existing right-angle splicing components for displays lack versatility, cannot quickly switch between vertical splicing, flat splicing, or curved splicing, and their installation and disassembly processes are cumbersome and the splicing speed is slow, reducing the flexibility of the equipment. Summary of the Invention

[0059] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0060] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0062] To address the technical problems of existing right-angle splicing components for displays lacking versatility, being unable to quickly switch between vertical splicing, planar splicing, or curved splicing, and having cumbersome installation and disassembly processes, slow splicing speeds, and low operational flexibility, this embodiment provides a new display mounting frame and display device.

[0063] It should be understood that the orientation referred to in this embodiment is based on the normal operating state of the display device, with the side facing the user being front and the side away from the user being rear; the side facing the ground being down and the side away from the ground being up. Furthermore, in this embodiment, the first direction is the horizontal direction of the display device in normal operating state, and the second direction is the vertical direction.

[0064] Please see Figures 1 to 26 The display device 100 in this embodiment includes a screen body 20 and a display screen mounting frame 10. The screen body 20 is an LED screen unit for displaying images, and the screen body 20 is mounted on the front side of the display screen mounting frame 10.

[0065] Please see Figure 2 and Figure 3 In some embodiments, the front side of the display mounting frame 10 is provided with a second magnetic element 113; the side of the screen body 20 facing the display mounting frame 10 is provided with a magnetic adsorption element 21 corresponding to the second magnetic element 113, so that the screen body 20 can be fixed to the display mounting frame 10 by magnetic attraction.

[0066] Specifically, a plurality of second magnetic elements 113, which are permanent magnets, are fixedly disposed on the periphery of the front side of the display mounting frame 10. A plurality of mutually spaced magnetic adsorption elements 21 are disposed on the periphery of the screen body 20 facing the display mounting frame 10. The magnetic adsorption elements 21 can be cylindrical. The magnetic adsorption elements 21 correspond to the second magnetic elements 113, so that when the screen body 20 is close to the display mounting frame 10, the magnetic adsorption elements 21 on the screen body 20 can form magnetic coupling with the second magnetic elements 113, allowing the screen body 20 to be securely fixed to the front side of the display mounting frame 10 without additional mechanical fasteners.

[0067] The installation of the screen body 20 is accomplished through magnetic adsorption, simplifying the assembly process and improving installation efficiency. Furthermore, due to the reversibility of the magnetic connection, users only need to overcome the magnetic force to remove the screen body 20 from the mounting frame, significantly improving the convenience of equipment maintenance and replacement.

[0068] Please see Figures 4 to 9 In this embodiment, the display screen mounting frame 10 includes a cabinet frame 11, a locking assembly 12, a fixing lock 13, and an arc-shaped lock 14.

[0069] The enclosure frame 11 has beveled surfaces 111 on its periphery; multiple mounting portions 112 are located on one side of the enclosure frame 11 near one of the beveled surfaces 111. A latch assembly 12 is mounted on the mounting portion 112 of the enclosure frame 11 and is movable within the mounting portion 112 to form a first position and a second position. The latch assembly 12 is in the first position when fixed to the side near the beveled surface 111, and in the second position when fixed to the side away from the beveled surface 111. A fixed lock 13 is fixed to the side of the enclosure frame 11 opposite to the latch assembly 12 and is used to connect with the latch assembly 12. An arc-shaped lock 14 is detachably connected to the fixed lock 13 of the enclosure frame 11 and is used to connect with the latch assembly 12.

[0070] When the locking assembly 12 is in the first position and connected to the arc-shaped lock 14 of another display mounting frame 10, the adjacent display mounting frames 10 are spliced ​​into a flat or arc-shaped structure. When the locking assembly 12 is switched to the second position and the arc-shaped lock 14 is removed, so that the locking assembly 12 is connected to the fixed lock 13 of another display mounting frame 10, the beveled surfaces 111 of the adjacent cabinet frames 11 abut against each other and are fixed to form a three-dimensional splicing structure.

[0071] Specifically, the cabinet frame 11 has a rectangular structure, and each of its four sides is machined with a beveled surface 111. The beveled surfaces 111 can abut and fit together during three-dimensional splicing of adjacent cabinet frames 11, thereby improving stability. The angle between the beveled surface 111 and the display plane where the screen body 20 is located can be set according to actual needs. In this embodiment, the angle between the beveled surface 111 and the display plane can be 45°, so that the two cabinet frames 11 are perpendicularly spliced ​​during three-dimensional splicing. Of course, the angle between the beveled surface 111 and the display plane can also be other angles, resulting in different corners during three-dimensional splicing to suit different usage environments.

[0072] Please see Figure 4 and Figure 5The cabinet frame 11 has multiple spaced mounting portions 112 on the side near the beveled surface 111, located on the left side of the cabinet frame 11. A locking assembly 12 is movably mounted within the mounting portion 112 and can move along a preset direction to form a first and second position at different locations. When the locking assembly 12 moves to the side near the beveled surface 111, it is in the first position (0° position). In this state, the locking assembly 12 can engage with the arc-shaped lock 14 on another display mounting frame 10, allowing adjacent mounting frames to be spliced ​​in a planar or arc-shaped manner. When the locking assembly 12 moves to the side away from the beveled surface 111, it is in the second position (90° position). In this state, the locking assembly 12 can connect with the fixed lock 13, achieving vertical three-dimensional splicing between adjacent cabinet frames 11. Users only need to perform simple loading and unloading operations as needed when switching between different splicing methods, greatly improving the flexibility of the equipment.

[0073] In this embodiment, the left side of the box frame 11 has three mounting parts 112 at the upper, middle, and lower positions, and the right side of the box frame 11 has three corresponding mounting positions for fixing locks 13 and arc-shaped locks 14. Figure 23 As shown, when the cabinet frame 11 is spliced ​​with a standard 500mm*500mm short box 200, the locking assembly 12 can be set on the upper and lower mounting parts 112, so that it can dock with the standard straight-screen short box 200. Figure 24 and Figure 25 As shown, when it is necessary to splice with the standard long box 300 (500mm*1000mm), the upper locking assembly 12 and the arc-shaped lock 14 can be switched to the middle of the box frame 11, so that the box formed by vertically splicing the two box frames 11 can be connected with the standard long box 300. The standard short box 200 and the standard long box 300 have traditional box structures, and their sides do not have bevels; that is, their sides are perpendicular to the display plane.

[0074] It is conceivable that in some other embodiments, different numbers of mounting parts 112 and fixing locks 13 may be provided according to the size of the non-standard box that the box frame 11 needs to connect with. The locking assembly 12 and the arc lock 14 can be installed on the mounting parts 112 at different heights of the box frame 11 according to actual needs, so that the box frame 11 can be adapted to the splicing of more sizes of boxes.

[0075] Please see Figure 6 and Figure 7In some embodiments, the mounting portion 112 includes a limiting groove 1121 formed on the housing frame 11. The limiting groove 1121 extends along a first direction; both side walls of the limiting groove 1121 are provided with protruding ribs 1122 extending along the first direction. When the locking assembly 12 mates with the limiting groove 1121 along the first direction, the protruding ribs 1122 abut against the locking assembly 12, so that the locking assembly 12 can only move out of or into the limiting groove 1121 along the first direction.

[0076] Specifically, the left side of the housing frame 11 is provided with multiple vertically spaced limiting grooves 1121, which extend along a first direction to form an elongated cavity structure. The two side walls of the limiting grooves 1121 are respectively provided with protruding ribs 1122 extending along the first direction, thus narrowing the opening of the entire limiting groove 1121. During installation, the locking assembly 12 is inserted into the limiting grooves 1121 along the first direction to achieve docking. During assembly, the protruding ribs 1122 abut against the surface of the locking assembly 12, limiting the movement of the locking assembly 12 to linear movement along the first direction, thereby preventing the locking assembly 12 from falling off when released.

[0077] Please see Figure 6 In some embodiments, the mounting portion 112 further includes a slide rail 1123 and at least two sets of first locking positions 1124; the slide rail 1123 is disposed on the bottom wall of the limiting groove 1121 and extends along a first direction. The two sets of first locking positions 1124 are arranged at intervals along the first direction for fixing the locking assembly 12 to a first position and a second position, respectively.

[0078] Specifically, the slide rail 1123 is located on the bottom wall of the limiting groove 1121 and extends along the first direction. It provides a stable sliding trajectory for the locking assembly 12, allowing the locking assembly 12 to move smoothly left and right within the limiting groove 1121 and limiting the extreme positions of the locking assembly 12's movement. After assembly, the bottom structure of the locking assembly 12 cooperates with the slide rail 1123, achieving guidance and limiting through sliding engagement, preventing the locking assembly 12 from shaking in non-preset directions.

[0079] Two sets of spaced-apart first locking positions 1124 are provided at both ends of the slide rail 1123. Each set of first locking positions 1124 corresponds to a stable position for fixing the locking assembly 12 in the first or second position. When the locking assembly 12 moves within the slide rail 1123, after moving to a preset position, the first locking position 1124 engages with the bottom structure on the locking assembly 12, creating a snap-fit ​​or locking effect, thereby reliably fixing the locking assembly 12. The entire operation process requires no complex alignment or additional tools, ensuring rapid positioning and stable locking.

[0080] Please see Figure 7In some embodiments, the locking assembly 12 includes a socket 121 and a first locking lever 122. The socket 121 is disposed within a limiting groove 1121 and is slidable within the limiting groove 1121 in a first direction to switch the locking assembly 12 to a first position or a second position. The first locking lever 122 is movably connected to the socket 121 and is able to extend out of the socket 121 in the first direction to be engaged and fixed with a fixed lock 13 or an arc-shaped lock 14 on another display mounting frame 10.

[0081] The shape of the socket 121 is adapted to the shape of the limiting groove 1121, allowing the socket 121 to be inserted into the limiting groove 1121 and move left and right, thereby enabling the selection of the first and second positions. The first locking rod 122 is movably mounted on the socket 121 and can extend out of the socket 121 in a first direction under the user's driving action. When the first locking rod 122 extends, its annular groove at its end can engage and fix with the fixing lock 13 or arc-shaped lock 14 on the adjacent display screen mounting frame 10. This securely splices two adjacent display screen mounting frames 10 together to form an integrated frame structure.

[0082] Please see Figure 6 and Figure 7 In some embodiments, the locking assembly 12 includes a sliding pin 123 passing through the socket 121. The sliding pin 123 protrudes from the bottom surface of the socket 121 facing the housing frame 11 and is capable of being inserted into the slide rail 1123 of the limiting groove 1121, and the sliding pin 123 is slidable along the extension direction of the slide rail 1123.

[0083] Specifically, the sliding pin 123 is a columnar structure that passes through the socket 121. One end protrudes from the bottom of the socket 121 and faces the housing frame 11, allowing it to enter the slide rail 1123 on the bottom wall of the limiting groove 1121. It slides within the slide rail 1123 as the socket 121 moves. The sliding pin 123 and the slide rail 1123 cooperate to provide a clear guide for the sliding of the socket 121, ensuring that the socket 121 can only move left and right within the length of the slide rail 1123. This prevents the socket 121 from sliding out of the limiting groove 1121, improving the stability and reliability of the latch assembly 12. Furthermore, the extreme limiting function of the sliding pin 123 ensures that the socket 121 can accurately reach the first or second position when switched, and reliably engage with the corresponding locking structure, guaranteeing rapid switching between the first and second positions of the latch assembly 12.

[0084] Please refer to [link / reference] for further information. Figure 4 To prevent the sliding pin 123 from interfering with the socket 121 when it mates with the limiting groove 1121, the socket 121 can be inserted into the limiting groove 1121 first, and then the sliding pin 123 can be inserted into the bottom of the socket 121 through the slide rail 1123, thereby realizing the installation of the sliding pin 123.

[0085] Please see Figure 6 and Figure 7 In some embodiments, the latch assembly 12 includes a first fastener 124. The first fastener 124 passes through the socket 121 and protrudes from the bottom surface of the socket 121 facing the housing frame 11. The first fastener 124 can be fixed to at least two sets of first locking positions 1124 of the housing frame 11 to fix the latch assembly 12 in a first position or a second position.

[0086] Specifically, the first fixing member 124 can be a bolt passing through the socket 121. The first locking position 1124 can be a screw hole on the bottom wall of the limiting groove 1121. The screw holes are divided into two groups, respectively set at both ends of the slide rail 1123, with each group having two screw holes, one above the other. When the socket 121 slides to the first position (0° position), the bolt is passed through the socket 121, so that the end of the bolt is threadedly connected to the screw hole on the side near the chamfered surface 111, thereby keeping the latch assembly 12 in the first position. When the socket 121 needs to be moved to the second position (90° position), the bolt can be unscrewed first, then the socket 121 can be slid to the limit position of the slide rail 1123, and then the bolt can be engaged with the other group of screw holes on the side away from the chamfered surface 111, thereby fixing the latch assembly 12 in the second position. Through this structural design of the mounting part 112 and the latch assembly 12, the latch assembly 12 can quickly and accurately complete the position switching and achieve reliable fixation.

[0087] Of course, in some other embodiments, the first fixing member 124 and the first locking position 1124 can also be other connection structures that can be quickly locked and unlocked, such as buckles and slots, pins and slots with elastic heads, etc.

[0088] Please see Figure 5 and Figure 8 In some embodiments, the fixed lock 13 includes a first insertion hole 131 and a first locking plate assembly 132. The first insertion hole 131 is disposed on the housing frame 11, and the axis of the first insertion hole 131 is perpendicular to the plane of the housing frame 11; the first locking plate assembly 132 is disposed in the axial direction of the first insertion hole 131 of the housing frame 11, and the first locking plate assembly 132 can be engaged and fixed with the locking assembly 12 inserted into the first insertion hole 131.

[0089] Specifically, the fixed lock 13 consists of a first insertion hole 131 and a first locking plate assembly 132. The first insertion hole 131 is formed on the cabinet frame 11, and its axis is perpendicular to the plane of the cabinet frame 11. The first locking plate assembly 132 is arranged along the axial direction of the first insertion hole 131, and it can engage with the end of the first locking rod 122 of the locking assembly 12, so that the first locking rod 122 of the locking assembly 12 can be inserted and fixed in the vertical direction during the insertion process, thereby realizing the vertical splicing of adjacent display screen mounting frames 10.

[0090] Please see Figure 5 In some embodiments, the first locking plate assembly 132 includes a locking plate 1321 and an elastic member 1323. The locking plate 1321 is movably disposed within the housing frame 11 and can move along an axis perpendicular to the first insertion hole 131 to open or close the first insertion hole 131. The two ends of the elastic member 1323 abut against the locking plate 1321 and the housing frame 11 respectively, to drive the locking plate 1321 to automatically reset to the closed state of the first insertion hole 131, thereby engaging and fixing with the first locking rod 122 of the latching assembly 12 inserted into the first insertion hole 131.

[0091] Specifically, the front side of the housing frame 11 is provided with multiple mounting slots, and each mounting slot is equipped with a locking plate 1321 and an elastic element 1323. The first locking plate assembly 132 also includes a locking plate cover plate 1322, which is fixed to the slot opening of the mounting slot by screws and is flush with the front side of the housing frame 11 to fix the locking plate 1321 and the elastic element 1323 inside the housing frame 11.

[0092] The locking plate 1321 extends out of the housing frame 11 and can move in a direction perpendicular to the axis of the first insertion hole 131, so that the locking plate 1321 can be pulled open when the first locking rod 122 of the locking assembly 12 is inserted into the first insertion hole 131. After the first locking rod 122 is fully inserted, the locking plate 1321 automatically resets under the action of the elastic element 1323, partially closing the first insertion hole 131, thereby realizing the locking plate 1321 and the end of the first locking rod 122 being engaged and fixed by the annular groove.

[0093] Please see Figure 8 and Figure 9 In some embodiments, the arc-shaped lock 14 includes a base 141 and a connecting seat 142. The base 141 is detachably connected to the back side of the housing frame 11 and is located in the area where the lock 13 is fixed. The connecting seat 142 is rotatably connected to the base 141, and a second locking plate assembly 1421 is provided on the side of the connecting seat 142 opposite to the base 141. The second locking plate assembly 1421 is used to engage and fix with the first locking rod 122 on the bolt lock assembly 12.

[0094] Specifically, the base 141 is detachably mounted on the back side of the housing frame 11 and positioned in the area corresponding to the fixed lock 13, thereby ensuring that the arc-shaped lock 14 can form a corresponding locking relationship with the first locking rod 122 of the latch assembly 12 after installation. The connecting seat 142 is connected to the base 141 via a hinge structure, allowing it to rotate relative to the base 141 within a certain angle range, thus enabling the connecting seat 142 to adjust its own angle by a small angle.

[0095] After two adjacent box frames 11 are spliced ​​together by the arc-shaped lock 14, the angle between the connecting seat 142 and the base 141 can be adjusted to make the adjacent box frames 11 be spliced ​​on the same plane. Alternatively, the angle between the connecting seat 142 and the base 141 can be adjusted within 15° to make the adjacent box frames 11 be joined together, forming multiple arc-shaped splices of adjacent box frames 11, thereby adapting to the installation requirements under different splicing configurations.

[0096] The connecting seat 142 is provided with a second locking plate assembly 1421. The structure of the second locking plate assembly 1421 is roughly the same as that of the first locking plate assembly 132. After the first locking rod 122 of the locking assembly 12 is inserted, it can be locked and fixed by the locking plate 1321.

[0097] Please see Figure 6 In some embodiments, a second fixing member 143 is provided on the base 141, and the second fixing member 143 extends out of the base 141 and faces the bottom surface of the housing frame 11. The housing frame 11 is provided with a second locking position 115, and the second fixing member 143 is detachably connected to the second locking position 115 so as to detachably connect the arc-shaped lock 14 to the housing frame 11.

[0098] Specifically, the base 141 of the arc-shaped lock 14 is provided with multiple second fixing parts 143, which are also bolts. The corresponding position on the box frame 11 is provided with a second locking position 115, which is a threaded hole.

[0099] When adjacent box frames 11 need to be joined on a flat or curved surface, i.e., when the curved lock 14 needs to be installed, the second fastener 143 can be inserted into the second locking position 115 along the direction perpendicular to the plane of the box frame 11, and tightened by screwing to complete the fixation, thereby reliably installing the curved lock 14 on the back side of the box frame 11. When vertical three-dimensional splicing is required, the second fastener 143 can be removed from the second locking position 115 to remove the curved lock 14 from the box frame 11, avoiding positional interference of vertical splicing of adjacent box frames 11.

[0100] Please see Figure 5In some embodiments, a first receiving groove is provided on the chamfered surface 111 of the box frame 11, and a first magnetic element 1111 is installed in the first receiving groove. When the chamfered surfaces 111 of adjacent box frames 11 abut, the first magnetic elements 1111 on the two box frames 11 attract each other to achieve magnetic fixation.

[0101] Specifically, to achieve a stable fixing effect during vertical three-dimensional assembly, each box frame 11 has a first receiving groove on its beveled surface 111, and a first magnetic component 1111 is embedded in the first receiving groove. When two box frames 11 abut against each other through the beveled surface 111 during installation, their respective first magnetic components 1111 generate magnetic attraction in contact or proximity, enabling adjacent box frames 11 to automatically align and achieve magnetic fixation. The magnetic attraction method on the beveled surface 111 not only reduces the complexity of manual alignment but also avoids gaps and step differences caused by mechanical alignment, thereby improving the overall flatness and appearance after assembly.

[0102] Please see Figure 13 and Figure 14 In some embodiments, the display mounting frame 10 further includes a first straight screen assembly 15 and a second straight screen assembly 16. The first straight screen assembly 15 and the second straight screen assembly 16 are detachably connected to opposite sides of the housing frame 11; the first straight screen assembly 15 on one display mounting frame 10 can be interconnected with the second straight screen assembly 16 on another display mounting frame 10, so that multiple display mounting frames 10 can be sequentially spliced ​​along a second direction.

[0103] The top of the box frame 11 is provided with a first straight screen assembly 15, and the bottom of the box frame 11 is provided with a second straight screen assembly 16. Both are detachably connected to the back of the box frame 11, so as to ensure quick assembly when the box frame 11 needs to be spliced ​​along the second direction.

[0104] Please see Figures 14 to 16 In some embodiments, the first straight-screen assembly 15 includes a first mounting plate 151 and a second locking rod 152 passing through the first mounting plate 151. The second locking rod 152 is movable in a second direction to extend out of the first mounting plate 151. The second straight-screen assembly 16 includes a second mounting plate 161 and a third locking plate assembly 163 fixed to the second mounting plate 161. The second mounting plate 161 is provided with a second insertion hole 162, which extends through the second mounting plate 161 in a second direction, and the second insertion hole 162 corresponds to the position of the second locking rod 152; the third locking plate assembly 163 is fixed in the axial extension direction of the second insertion hole 162 so as to be able to engage and fix with the second locking rod 152 passing through the second insertion hole 162.

[0105] Specifically, the first vertical screen assembly 15 is disposed at the top of the display mounting frame 10, and includes a first mounting plate 151 for support and positioning, and a second locking rod 152 passing through the first mounting plate 151. The first mounting plate 151 is mounted on the back edge of the housing frame 11, and the second locking rod 152 is movable along a second direction. When the second locking rod 152 extends along the second direction, it forms a plug-in end.

[0106] Conversely, the second straight screen assembly 16 is disposed at the bottom end of the housing frame 11, and includes a second mounting plate 161 for support and positioning and a third locking plate assembly 163 fixed on the second mounting plate 161. A second insertion hole 162 is provided on the bottom surface of the second mounting plate 161, and the second insertion hole 162 vertically penetrates the second mounting plate 161 along a second direction, corresponding to the movement path of the second locking rod 152.

[0107] When the second locking rod 152 on the first straight screen assembly 15 extends along the second direction, it can smoothly pass through the second insertion hole 162 on the second mounting plate 161 on the other housing frame 11. A third locking plate assembly 163 is mounted on the second mounting plate 161, and is installed along the axial direction of the second insertion hole 162. The third locking plate assembly 163 has the same structure as the second locking plate assembly 1421. After the second locking rod 152 passes through the second insertion hole 162, the third locking plate assembly 163 engages with it, thereby achieving a secure lock between the first straight screen assembly 15 and the second straight screen assembly 16.

[0108] Please see Figure 13 and Figure 17 In some embodiments, the first straight screen component 15 and the second straight screen component 16 further include a quick-lock mechanism 17.

[0109] The two sides of the housing frame 11 are provided with locking plate units 114 corresponding to the quick-lock mechanism 17; the locking plate units 114 are engaged with the quick-lock mechanism 17 on the first straight screen assembly 15 and the second straight screen assembly 16 so that the first straight screen assembly 15 and the second straight screen assembly 16 can be detachably connected to the housing frame 11.

[0110] By connecting the quick-lock mechanism 17 with the locking plate unit 114, the installation and disassembly steps of the first vertical screen assembly 15 and the second vertical screen assembly 16 with the cabinet frame 11 can be simplified, reducing operational complexity and avoiding the time-consuming disassembly and assembly problems caused by using traditional screw fixing methods. This significantly improves the efficiency and flexibility of the display device 100 in vertical splicing or maintenance processes, meeting the actual needs of rapid splicing and convenient maintenance.

[0111] Please see Figure 17In some embodiments, the quick-lock mechanism 17 includes a bushing 171, a pull rod 172, and a handle 173. The pull rod 172 passes through the bushing 171 and is threadedly connected to the inner wall of the bushing 171. One end of the pull rod 172 is fixedly connected to the handle 173, and the other end of the pull rod 172 has a locking portion 1721. The locking plate unit 114 has a lock hole structure 1141, and a protrusion 1142 protrudes from the inner wall of the lock hole structure 1141. The protrusion 1142 is used to engage with the locking portion 1721.

[0112] Among them, the bushing 171 serves as a mounting base and is fixed to the mounting plate of the first straight screen assembly 15 or the second straight screen assembly 16. Its inner wall is machined with threads for threaded engagement with the pull rod 172, thereby ensuring that the pull rod 172 can both rotate and move forward and backward along the axial direction within the bushing 171.

[0113] The pull rod 172 is a connecting component of the quick-lock mechanism 17. One end of it is fixedly connected to the handle 173, and the user can drive the pull rod 172 to move it in and out by rotating the handle 173. The other end of the pull rod 172 is provided with a locking part 1721, which is usually a flange structure. The locking part 1721 has the same hole structure as the protrusion 1142 at the opening of the lock hole structure 1141, so that it can abut against the protrusion 1142 on the inner wall of the lock hole after the lock hole structure 1141 of the lock plate unit 114 is inserted.

[0114] During assembly, the user pushes the first straight screen assembly 15 or the second straight screen assembly 16 close to the housing frame 11, so that the locking part 1721 of the quick-lock mechanism 17 is aligned with the opening of the lock hole structure 1141 on the lock plate unit 114. The locking part 1721 can enter the lock plate unit 114 through the hole between the two protrusions 1142. Then, the pull rod 172 is rotated, causing the locking part 1721 to rotate along the axis of the pull rod 172 to be misaligned with the opening of the lock hole structure 1141, thereby forming a locking engagement with the protrusion 1142 on the inner wall of the lock hole structure 1141 to achieve fixation. The limiting relationship formed between the locking part 1721 and the protrusion 1142 can effectively prevent the display mounting frame 10 from shaking or falling off due to external force during use.

[0115] When disassembly is required, the user simply rotates the lever 172 via the handle 173, causing the latching part 1721 on the lever 172 to rotate to the same opening angle as the lock hole structure 1141. At this time, the latching part 1721 and the protrusion 1142 will not obstruct each other, thus unlocking can be achieved. The entire process requires no additional tools, is simple and quick to operate, and greatly improves the efficiency of on-site installation and disassembly of the first straight screen assembly 15 and the second straight screen assembly 16.

[0116] Please see Figure 17In some embodiments, the quick-lock mechanism 17 further includes a locking member 174. The locking member 174 is rotatably connected to the handle 173, and the end of the pull rod 172 near the handle 173 is provided with ratchet teeth that match the locking member 174. When the first end of the locking member 174 is pressed, causing the second end of the locking member 174 to disengage from the ratchet teeth on the pull rod 172, the handle 173 can drive the pull rod 172 to rotate; when the locking member 174 is released, causing the second end of the locking member 174 to abut against the ratchet teeth on the pull rod 172, the rotation of the pull rod 172 is locked.

[0117] Specifically, the locking element 174 is rotatably connected to the handle 173 via a pin with a torsion spring. Its second end is similar to a pawl, capable of engaging or disengaging with the pull rod 172. The end of the pull rod 172 near the handle 173 is machined with ratchet teeth, which are evenly distributed circumferentially and match the end of the locking element 174, used to lock the rotation of the pull rod 172 when needed.

[0118] In some embodiments, the ratchet teeth can be helical ratchet or spur ratchet. When the ratchet teeth are spur ratchet, the rotation of the lever 172 is completely locked when the locking member 174 abuts against the ratchet teeth. When the ratchet teeth are helical ratchet with a certain angle of inclination, the lever 172 can still rotate in one direction when the locking member 174 abuts against the ratchet teeth, but its rotation direction is the direction of retraction of the lever 172, that is, the lever 172 can only tighten the first vertical screen assembly 15 or the second vertical screen assembly 16 to the housing frame 11.

[0119] During use, when the user releases the locking member 174, its second end automatically abuts against the ratchet teeth of the pull rod 172 under the action of the torsion spring. At this time, the rotation of the pull rod 172 is restricted by the meshing relationship between the ratchet teeth and the locking member 174, so that even if the handle 173 is subjected to external force, it cannot unlock the pull rod 172 from the locking plate unit 114. This prevents the quick-lock mechanism 17 from loosening due to vibration or misoperation, and ensures the safe connection between the first straight screen assembly 15 and the second straight screen assembly 16 and the cabinet frame 11.

[0120] When adjustment or disassembly is required, the user simply presses the first end of the locking member 174 by hand, causing the locking member 174 to rotate around the pin. At this time, the rotation lock of the pull rod 172 is released. The handle 173 can drive the pull rod 172 to rotate freely, so that the snap-fit ​​part 1721 of the pull rod 172 can be disengaged from the lock hole structure 1141 of the lock plate unit 114, thereby realizing convenient disassembly and assembly operations.

[0121] By adding the locking element 174 to cooperate with the ratchet teeth, the pull rod 172 has dual limit protection. That is, on the basis of the pull rod 172 being self-locking and anti-loosening through the thread, a mechanical locking mechanism is used to prevent accidental rotation, thereby improving the overall safety and reliability of the quick-lock mechanism 17.

[0122] Please see Figure 14 and Figure 15 In some embodiments, the first straight-screen assembly 15 further includes a positioning component 18. The positioning component 18 is movably disposed on the first mounting plate 151 and can extend into the first mounting plate 151 in a second direction. The second mounting plate 161 of the second straight-screen assembly 16 is provided with a positioning hole 164. When the positioning component 18 extends out of the first mounting plate 151, it can be inserted into the positioning hole 164 to achieve a positioning connection between the first straight-screen assembly 15 and the second straight-screen assembly 16.

[0123] Specifically, when vertical splicing is required, the user can push the positioning component 18 to extend it along the second direction and insert it into the positioning hole 164 on the second mounting plate 161 of the second vertical screen component 16, thereby achieving precise positioning of the first vertical screen component 15 and the second vertical screen component 16. The positioning component 18 and the positioning hole 164 simplify the installation operation, eliminating the need for repeated adjustments during splicing and significantly improving splicing efficiency, while ensuring overall consistency of multiple display mounting frames 10 during large-scale splicing.

[0124] Please see Figure 15 , Figures 17 to 21 In some embodiments, the positioning component 18 includes a positioning post 181, a limiting pin 182, and a connecting screw 183.

[0125] The first mounting plate 151 has a limiting hole on its side, which has two fixed positions spaced apart along the second direction. A positioning pin 181 extends along the second direction. One end of a connecting screw 183 is fixedly connected to the positioning pin 181, and the other end of the connecting screw 183 extends out of the side of the first mounting plate 151 along the limiting hole. A limiting pin 182 is sleeved on the connecting screw 183 and can move axially along the connecting screw 183. When the limiting pin 182 moves and inserts into the fixed position of the limiting hole, the positioning pin 181 is fixed in the extended or retracted state.

[0126] Specifically, the positioning post 181 has a strip-shaped or cylindrical structure and extends along the second direction. When extended, the positioning post 181 can be inserted into the positioning hole 164 of the second straight screen assembly 16 to achieve precise alignment of the two mounting plates. One end of the connecting screw 183 is fixedly connected to the positioning post 181, forming an L-shaped structure, which allows the positioning post 181 to be guided and moved inside the first mounting plate 151; the other end of the connecting screw 183 passes through the limiting hole on the side of the first mounting plate 151 and extends outside the first mounting plate 151.

[0127] A limiting hole is formed on the side of the first mounting plate 151. The limiting hole has two fixing positions arranged at intervals along the second direction, corresponding to the "fully extended" and "fully retracted" states of the positioning post 181, respectively. When the positioning post 181 is in the extended state, it can be inserted into the positioning hole 164 of the adjacent component, thereby completing precise alignment. When the positioning post 181 is in the retracted state, it is completely housed within the first mounting plate 151, avoiding interference during transportation or when splicing is not required.

[0128] The limiting pin 182 is sleeved on the connecting screw 183 and can move along the axial direction of the connecting screw 183 to lock and release. When the limiting pin 182 moves out of the limiting hole, the user can drive the positioning pin 181 to extend or retract; when the limiting pin 182 is inserted into the fixed position of the limiting hole, the connecting screw 183 is fixed, thereby fixing the corresponding position of the positioning pin 181.

[0129] The limiting pin 182, through its fixed engagement with the limiting hole, ensures the stability of the positioning post 181 under both working conditions, preventing wobbling or accidental retraction of the positioning post 181 during assembly and improving the accuracy and reliability of the assembly positioning. Furthermore, users can quickly switch the position of the positioning post 181 simply by pushing or pulling the limiting pin 182, simplifying operation and significantly reducing preparation time for assembly and installation.

[0130] Please see Figure 15 In some embodiments, the positioning component 18 further includes a compression spring 184, which is sleeved on the connecting screw 183 and located between the limiting pin 182 and the nut of the connecting screw 183, to provide a stable restoring force for the limiting pin 182.

[0131] When the operator pulls the limit pin 182 out of the fixed position of the limit hole and moves it up and down to change the state of the positioning post 181, the compression spring 184 generates a thrust through the stored elastic potential energy, causing the limit pin 182 to automatically slide back to the fixed position of the limit hole along the connecting screw 183, thereby completing the extension or retraction switch of the positioning post 181 and ensuring that the display screen mounting frame 10 can be quickly and accurately positioned during the splicing process.

[0132] Please see Figure 15 In some embodiments, the first vertical screen assembly 15 further includes a handle 153, which is fixed to the side of the first mounting plate 151 opposite to the housing frame 11. Users can directly hold and adjust the position of the display mounting frame 10 through the handle 153, thereby further improving the ease of operation.

[0133] Please see Figure 1In some embodiments, the display mounting frame 10 further includes a power supply box 19. The power supply box 19 is disposed on the back side of the housing frame 11 and is fixed to the housing frame 11 by a detachable connection, facilitating installation and disassembly. The power supply box 19 contains a circuit module that supplies power to the screen body 20, and achieves stable power supply by interfacing with the power interface of the display screen. The power supply box 19 and the housing frame 11 can be connected by a structure such as a snap-fit, screw, or sliding guide rail, quick-lock mechanism 17, etc., to improve ease of use and maintenance efficiency.

[0134] Please see Figures 22 to 29 This embodiment also provides various splicing methods for display devices 100.

[0135] like Figure 22 As shown, when the display devices 100 are vertically spliced, the first vertical screen assembly 15 and the second vertical screen assembly 16 are first installed at the top and bottom of the cabinet frame 11, respectively. When adjacent cabinet frames 11 are aligned vertically, the positioning post 181 can be accurately inserted into the corresponding positioning hole 164, playing a preliminary limiting and guiding role. Subsequently, it is reliably fixed by the second locking rod 152 and the third locking piece assembly 163, so that multiple display screen mounting frames 10 can be spliced ​​vertically.

[0136] like Figure 22 As shown, when horizontal expansion along the first direction is needed to form a large screen splicing, the locking assembly 12 can be placed in the first position. At this time, the first locking rod 122 of the locking assembly 12 can be inserted into the arc-shaped lock 14 on another housing frame 11, completing the horizontal fixation of the adjacent display screen mounting frames 10. The arc-shaped lock 14 itself has an adjustable angle structure, allowing for fine rotation adjustment after insertion, so that the overall structure of the splicing screen can not only maintain a straight splice but also achieve a certain degree of curvature splicing effect to meet diverse display needs such as exhibitions, stages, and studios. Of course, as... Figures 23 to 25 As shown, the display screen mounting frame 10 can also be docked with the standard short box 200 or the standard long box 300 to achieve flat or curved splicing.

[0137] like Figure 26 As shown, when vertical 3D splicing is required, the arc-shaped lock 14 must be disassembled first, and then the locking assembly 12 must be switched to the second position. At this time, the first locking rod 122 of the locking assembly 12 is connected to the fixed lock 13, allowing adjacent box frames 11 to be connected vertically in space, thereby constructing a stable 3D splicing structure. This enables spatial splicing effects such as 3D advertising pillars and two-sided 3D display screens.

[0138] like Figures 27 to 29When a three-sided 3D cube needs to be assembled, the first vertical screen component 15 and the second vertical screen component 16 can be detached from the cabinet frame 11. Then, multiple three-sided right-angle connecting pieces 30 are installed at the top of the cabinet frame 11. The three-sided right-angle connecting pieces 30 can be inserted into three cabinet frames 11 simultaneously, so that the top cabinet frame 11 is stably installed on the top surface of the two cabinet frames 11 that have been vertically assembled. By repeating this process, a 3D cube display structure can be finally formed to meet the needs of immersive exhibition halls, commercial windows, or 3D advertising displays.

[0139] In summary, this application provides a display screen mounting frame 10 and a display device 100. The housing frame 11 of the display screen mounting frame 10 is equipped with a locking assembly 12 that can switch between a first position and a second position.
