[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0026] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0027] See also Figures 1 to 8 The display screen 3 includes a frame 1 and a panel 2, and the panel 2 is mounted on the frame 1. In some embodiments, the panel 2 is a display module, that is, the panel 2 includes an LED light board and a bottom shell (in some embodiments, there may be no bottom shell). The frame 1 includes a frame body 100 and a disassembly assembly 200, and multiple display screens 3 can be assembled with each other through the first fixing seat 10 and the second fixing seat 20 on the frame body 100, respectively, to achieve side-by-side connection to form a single display device 1000, or disassembled from each other to separate multiple display screens 3 into monomers.

[0028] The disassembly assembly 200 includes a first fixing seat 10, a second fixing seat 20 and a locking rod 21. The first fixing seat 10 and the second fixing seat 20 are respectively arranged on two opposite sides of the frame 100, and the first fixing seat 10 has an opposite outer wall surface 11 and an inner wall surface 12, and a locking hole 13 penetrating the outer wall surface 11 and the inner wall surface 12. The second fixing seat 20 is penetrated by a locking rod 21, and the locking rod 21 can rotate on the second fixing seat 20 and move relative to the second fixing seat 20 along the axial direction of the locking rod 21. It is worth noting that in some embodiments, the first fixing seat 10 and the second fixing seat 20 can be fixed to two opposite sides of the frame 100 by screws, or the first fixing seat 10 is a part of the frame 100, and the outer wall surface 11, the inner wall surface 12 and the locking hole 13 and other structures are directly formed on the frame 100.

[0029] The head end 21A of the lock rod 21 is provided with a pin shaft 211 protruding radially along the lock rod 21. When the lock rod 21 drives the pin shaft 211 to rotate to a first angle, the pin shaft 211 is aligned with the lock hole 13 and can pass through the lock hole 13, and can move between the outer wall surface 11 and the inner wall surface 12. And, when the lock rod 21 drives the pin shaft 211 to rotate to a second angle, the pin shaft 211 is misaligned with the lock hole 13, so that the pin shaft 211 is stopped on one side of the outer wall surface 11, or is limited to one side of the inner wall surface 12.

[0030] For example, the locking hole 13 extends in one direction on the surface of the first fixing seat 10 to form a straight hole, and the first angle and the second angle differ by approximately 90 degrees. When the pin 211 is located on one side of the outer wall 11, if the locking rod 21 drives the pin 211 to rotate to the first angle, so that the angle of the pin 211 is aligned with the angle of the locking hole 13, for example, in the same horizontal state as the locking hole 13, the pin 211 can move in and out of the locking hole 13 (such as Figure 5 and Figure 6 On the contrary, if the lock rod 21 drives the pin 211 to rotate to a second angle, the angle of the pin 211 and the angle of the lock hole 13 are misaligned, for example, the pin 211 is vertical, while the lock hole 13 is horizontal, so that the pin 211 cannot enter or exit the lock hole 13 and is stopped by the outer wall 11.

[0031] Therefore, when the pin 211 is located on one side of the inner wall surface 12, the lock rod 21 drives the pin 211 to rotate to the second angle, so that the pin 211 is in a vertical state and intersects with the horizontal state of the lock hole 13, so that the pin 211 is limited on the inner wall surface 12, so that the first fixing seat 10 and the second fixing seat 20 are combined with each other (such as Figure 7 and Figure 8 Similarly, when the first fixing seat 10 and the second fixing seat 20 need to be separated, the pin 211 only needs to be rotated from the second angle to the first angle (that is, from Figure 7 Reply to Figure 6 state), the pin 211 can be moved out of the lock hole 13 (that is, by Figure 6 Change to Figure 5 status).

[0032] It can be understood that, when assembling two adjacent display screens 3, it is only necessary to arrange the second fixing base 20 of one display screen 3 and the first fixing base 10 of the other display screen 3 side by side, let the locking rod 21 of one display screen 3 pass through the locking hole 13 of the other display screen 3, and rotate the pin shaft 211 between the second angle and the first angle, so that the two adjacent display screens 3 can be combined with and separated from each other accordingly.

[0033] In some embodiments, the second fixing seat 20 has a first side surface 22 and a second side surface 23 opposite to each other, and a mounting hole 24 penetrating the first side surface 22 and the second side surface 23. The diameter of the mounting hole 24 is smaller than the diameter of the tail end 21B of the locking rod 21, and matches the diameter of the head end 21A of the locking rod 21. The locking rod 21 is inserted into the mounting hole 24, and the pin 211 and the tail end 21B of the locking rod 21 correspond to the outside of the first side surface 22 and the second side surface 23, respectively, so that the pin 211 can stop the head end 21A of the locking rod 21 from moving toward the second side surface 23, and the tail end 21B of the locking rod 21 can stop the locking rod 21 from moving toward the first side surface 22, thereby preventing the locking rod 21 from being separated from the mounting hole 24.

[0034] In other embodiments of the present application, a through hole 25 is provided in the radial direction at the head end 21A of the locking rod 21. The pin 211 is inserted into the through hole 25, and at least one of the two opposite ends of the pin 211 is exposed outside the through hole 25. For example, a concave-convex matching structure or an elastic snap-fit ​​structure is provided between the through hole 25 and the pin 211, so that the pin 211 is snap-fitted and positioned in the through hole 25 after being inserted into the through hole 25, or the pin 211 is fixed by welding or a tight fit after being inserted into the through hole 25. It is understandable that during assembly, the head end 21A of the locking rod 21 is first inserted into the mounting hole 24 from the second side surface 23 of the second fixing seat 20, and when extending from the first side surface 22 to the first fixing seat, the pin 211 is inserted into the through hole 25 to complete the installation of the locking rod 21.

[0035] In some embodiments of the present application, the tail end 21B of the locking rod 21 is further provided with a handle 27, one end of the handle 27 is sleeved on the tail end 21B of the locking rod 21, and a matching internal and external thread structure is provided between the two. The inner wall surface 12 is provided with a limiting groove 121. The limiting groove 121 is recessed in the inner wall surface 12, and the extending directions of the limiting groove 121 and the lock hole 13 on the inner wall surface 12 intersect. For example, the pin 211 is a cylindrical structure, and the limiting groove 121 is an arc-shaped groove. When locking two adjacent display screens 3, the handle 27 has a two-stage rotation. The first stage: rotate the handle 27 so that the locking rod 21 drives the pin 211 to align with the lock hole 13, and then push the handle 27 in the direction of the lock hole 13 to allow the pin 211 to pass through the lock hole 13. Then, the handle 27 is rotated, and the friction force of the thread is used to drive the locking rod 21 to rotate together, so that the pin shaft 211 extending into the lock hole 13 is rotated into the limiting groove 121 to lock the locking rod 21. The second stage: the handle 27 is continued to be rotated. At this time, the locking rod 21 does not move, and the handle 27 rotates to approach the second fixing seat 20 until the handle 27 abuts against the second fixing seat 20 to lock the locking rod 21. When splitting two adjacent display screens 3, the handle 27 is rotated in the opposite direction, and the handle 27 rotates away from the second fixing seat 20. After the handle 27 is separated from the second fixing seat 20, the handle 27 is pushed and rotated in the direction of the lock hole 13, so that the pin shaft 211 is disengaged from the limiting groove 121, and after being aligned with the lock hole 13, the locking rod 21 drives the pin shaft 211 to be pulled out of the lock hole 13 to complete the unlocking operation. In the process of locking or unlocking, the present application only needs to operate the handle 27, and the operation is simple and convenient.

[0036] In some embodiments, the handle 27 includes a sleeve 271 and a lever 272 connected to one side of the sleeve 271. The sleeve 271 is sleeved on the tail end 21B of the locking rod 21, and a matching internal and external thread structure is provided between the sleeve 271 and the tail end 21B of the locking rod 21. In this embodiment, a portion of the tail end 21B of the locking rod 21 is configured in the form of a screw, a male thread is provided on the tail end 21B, and the sleeve 271 is provided with a through hole, and a female thread matching the male thread is provided in the through hole.

[0037] For example, the tail end 21B of the locking rod 21 includes a docking portion 28 and a stopper 29, wherein the stopper 29 is disposed on the side of the docking portion 28 facing away from the head end 21A, and the outer diameter of the stopper 29 is greater than the outer diameter of the docking portion 28. The male thread of the threaded structure is disposed on the docking portion 28, so that when the sleeve 271 is sleeved on the docking portion 28, the male thread and the female thread are meshed with each other to be firmly combined with the locking rod 21, and the end surface of the sleeve 271 abuts against the stopper 29 to prevent the sleeve 271 from being separated from the docking portion 28.

[0038] In some embodiments, the locking rod 21 is further provided with an elastic member 26, and a step structure 241 is further provided in the mounting hole 24 of the second fixing seat 20 (see Figure 8 ). In the present embodiment, the mounting hole 24 forms two channels that are interconnected and have different diameters in the second fixing seat 20, and the step structure 241 is formed at the connection of the two channels. The diameter of one of the channels matches the moving space of the locking rod 21 and the pin 211, so that the locking rod 21 and the pin 211 can move in and out of this channel, and even the pin 211 can normally maintain a state of the first angle in this channel. The other channel forms an opening with a relatively large diameter on the second side 23, so that the elastic member 26 can be accommodated therein. The elastic member 26 can be, but is not limited to, a compression spring sleeved on the locking rod 21, and the opposite ends of the elastic member 26 correspond to the step structure 241 and the tail end 21B of the locking rod 21, respectively, to provide an elastic force from the first side 22 to the second side 23. Therefore, when the pin shaft 211 rotates to the second angle on one side of the inner wall surface 12, the elastic force of the elastic member 26 can push between the step structure 241 and the tail end 21B of the locking rod 21, and pull the locking rod 21 from the first side surface 22 to the second side surface 23, and at the same time pull the pin shaft 211 on the inner wall surface 12 to press against the groove surface of the limiting groove 121 to enhance the coupling effect.

[0039] When connecting, the handle 27 is pushed so that the lock rod 21 drives the pin 211 to extend into the lock hole 13, and then the handle 27 is rotated forward so that the pin 211 is rotated from the first angle to the second angle and is engaged in the limiting groove 121. At this time, because one end of the elastic member 26 abuts against the step structure 241 and the other end abuts against the docking portion 28, when the thrust applied to the handle 27 is released, the elastic restoring force of the elastic member 26 acts on the docking portion 28 and the step structure 241 respectively, so that the lock rod 21 is pushed by the elastic member 26 and the pin 211 is pulled in a direction away from the first fixing seat 10 to abut against the groove surface of the limiting groove 121. That is, under the elastic force of the elastic member 26, the lock rod 21 is pulled toward the handle 27 so that the pin 211 remains stuck in the limiting groove 121. When the pin 211 is inserted into the limiting groove 121, the handle 27 continues to be rotated. Since the locking rod 21 cannot rotate with the handle 27, the handle 27 rotates toward the second fixing seat 20 and presses against the second fixing seat 20, which can prevent the pin 211 from being disengaged from the limiting groove 121, thereby locking the locking rod 21 and realizing the combination of two adjacent LED display screens.

[0040] In addition, in order to prevent the handle 27 from being easily loosened after being pressed against the second fixing seat 20, in some embodiments, the disassembly assembly 200 further includes a gasket 201, which may be but is not limited to being made of a compressible and deformable material, such as a rubber gasket. The gasket 201 is disposed on the second side surface 23 of the second fixing seat 20, and the locking rod 21 can pass through. Therefore, after the handle 27 is pressed against the second side surface 23 of the second fixing seat 20, the gasket 201 is squeezed and deformed between the second side surface 23 and the sleeve 271 of the handle 27, thereby providing additional resistance to prevent the handle 27 from being loosened.

[0041] During disassembly, the handle 27 only needs to be rotated in the opposite direction so that the handle 27 moves relative to the locking rod 21 in a direction away from the second fixing seat 20. Then, the handle 27 is pushed in the direction of the second fixing seat 20 so that the pin 211 leaves the limiting groove 121. At this time, the handle 27 is continued to be rotated to drive the pin 211 to rotate toward the first angle so that the direction of the pin 211 coincides with the direction of the locking hole 13. Then, through the elastic restoring force of the elastic member 26 and / or the pulling of the handle 27, the locking rod 21 is moved toward the direction of the second fixing seat 20, and the pin 211 is pulled out from the locking hole 13 to one side of the outer wall surface 11, thereby realizing the separation of the two adjacent display screens 3. In some embodiments, the disassembly assembly 200 further includes a rubber ring 202, which is sleeved on the locking rod 21 and is located between the locking rod 21 and the handle 27. For example, the rubber ring 202 is sleeved on the outer periphery of the docking portion 28 of the locking rod 21 and is located at the junction of the docking portion 28 and the stopper 29. When the handle 27 rotates in the opposite direction during the disassembly process, so that the handle 27 moves relative to the locking rod 21 in a direction away from the second fixing seat 20, the rubber ring 202 is clamped between the stopper 29 and the sleeve 271, thereby increasing the friction between the locking rod 21 and the handle 27, ensuring that the handle 27 is firmly positioned, and maintaining a gap between the sleeve 271 of the handle 27 and the second side surface 23 of the second fixing seat 20, so that the handle 27 can be pushed toward the second fixing seat 20 to make the pin 211 leave the limiting groove 121.

[0042] In some embodiments of the present application, the first fixing seat 10 further has a cavity 122 on one side of the inner wall surface 12, and a guide structure 123 is arranged in the cavity 122. The guide structure 123 is located between the limit groove 121 and the lock hole 13 in the projection direction of the inner wall surface 12, for example, located in a corner adjacent to the lock hole 13 in the cavity 122, so as to limit the pin 211 to rotate only between the first angle and the second angle. In this embodiment, the cavity 122 is a hollow structure surrounded by the inner wall surface 12 and other connected wall surfaces, and the lock hole 13 and the limit groove 121 are approximately cross-shaped on the inner wall surface 12. The guide structure 123 is a rectangular block protruding from the inner wall surface 12, and is located at the lower left (or lower right) of the cross-shaped shape formed by the limit groove 121 and the lock hole 13. In this way, when the pin shaft 211 is rotated to the first angle, it abuts against the top surface of the guide structure 123, and when it is rotated to the second angle, it abuts against the side surface of the guide structure 123. The rotation direction of the pin shaft 211 is restricted, achieving a two-stage switching effect and a fool-proof effect, allowing the user to switch easily and avoiding excessive rotation and failure to accurately rotate to the angle that aligns or misaligns the pin shaft 211 and the lock hole 13.

[0043] In addition, in order to facilitate the user to clearly identify the rotation angle of the pin 211, in some embodiments, the top surface of the second fixing seat 20 is further provided with an alignment mark 210 (see Figure 5), and a first indicator mark 291 and a second indicator mark 292 are arranged at intervals on the outer circumferential surface of the stopper 29. Figure 5 and Figure 7 As shown, when the lock bar 21 drives the pin 211 to rotate to the first angle, the first indicator mark 291 rotates synchronously to the position corresponding to the alignment mark 210, and when the lock bar 21 drives the pin 211 to rotate to the second angle, the second indicator mark 292 rotates synchronously to the position corresponding to the alignment mark 210, and the first indicator mark 291 is misaligned with the alignment mark 210. In this way, the user can easily identify whether the pin 211 is at the first angle or the second angle through the corresponding states of the alignment mark 210 and the first indicator mark 291 and the second indicator mark 292, so as to facilitate assembly or disassembly operations.

[0044] The above is only an embodiment of the present application and is not intended to limit the present application.
