[0035] When an LED display screen is applied, it needs to be disassembled, transported, and assembled. During assembly, it is achieved by splicing and fixing the boxes of the display screen to each other. With frequent disassembly and assembly, the top corners of the boxes of the display screen are prone to being knocked and deformed, which easily causes gaps between two display screens or damages the LED lamp beads at the top corner positions. Therefore, it is necessary to develop a structure that can protect the corners of the boxes without hindering the assembly of the boxes.

[0036] The present utility model provides a corner protection component, which can be used to protect the corners of the boxes and at the same time avoid affecting the assembly of the boxes.

[0037] Furthermore, the present utility model proposes a display screen applying the above corner protection component.

[0038] Refer to Figures 1 to 5, the corner guard assembly according to the first aspect embodiment of the present utility model includes a mounting portion 100, a folding portion 200, and a corner guard portion 300, wherein the mounting portion 100 is used to be mounted on the box body 500 of the LED display screen. The folding portion 200 is rotatably connected to the mounting portion 100, and the corner guard portion 300 is disposed on the folding portion 200. The folding portion 200 has an unfolded state and a folded state during the process of rotating relative to the mounting portion 100. In the unfolded state, the angle between the folding portion 200 and the mounting portion 100 increases, and the distance between the folding portion 200 and the mounting portion 100 increases. In the folded state, the angle between the folding portion 200 and the mounting portion 100 decreases, and the distance between the folding portion 200 and the mounting portion 100 decreases. Since the corner guard portion 300 is mounted on the folding portion 200, when the folding portion 200 rotates to the unfolded state, the distance between the corner guard portion 300 and the mounting portion 100 increases, and when the folding portion 200 rotates to the folded state, the distance between the corner guard portion 300 and the mounting portion 100 decreases. Further, it can be understood that the corner guard portion 300 has multiple position states during the rotation of the folding portion 200. The mounting portion 100 can be mounted at an appropriate position on the back of the box body 500 of the LED display screen, so that when the folding portion 200 is unfolded, the corner guard portion 300 is just located at the top corner position of the box body 500, thereby realizing the protection of the top corner of the box body 500 and avoiding bumping and deformation. When assembling, the folding portion 200 can be rotated to the folded state, so that the corner guard portion 300 withdraws from the top corner position of the box body 500, enabling the box bodies 500 to be assembled smoothly. Therefore, the corner guard assembly in the present utility model can not only achieve the protection of the corners of the box body 500, improve the service life and splicing effect, but also yield during assembly and will not interfere with the assembly of the box body 500.

[0039] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the corner guard portion 300 is rotatably connected to the folding portion 200. In this way, when the folding portion 200 rotates relative to the mounting portion 100 to unfold or fold, the corner guard portion 300 and the folding portion 200 can also be unfolded and folded, so as to better protect the top corner of the box body 500 and better fold and yield to avoid affecting the assembly of the box body 500.

[0040] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the folding portion 200 is provided with a reset structure, and the reset structure is used to keep the folding portion 200 in the unfolded state. In this embodiment, the reset structure is used to ensure that the folding portion 200 is in the unfolded state when not affected by external forces, which is beneficial to the protection of the top corner of the box body 500 by the corner guard portion 300. Under the action of the reset structure, the corner guard portion 300 can ensure the stability of the position for protecting the top corner of the box body 500, and avoid the situation that the corner guard portion 300 is non-controlledly displaced, resulting in the top corner of the box body 500 being bumped and damaged.

[0041] Reference Figure 3 and Figure 4 Figure 4

[0042] Reference Figure 3 Figure 3

[0043] Reference Figure 2 and Figure 3 Figure 3

[0044] Reference Figure 4 In some embodiments of the present invention, the corner guard 300 is provided with a platform 301 protruding toward the position of the clearance opening 203, and a buckle recess 302 is provided at one end of the platform 301 away from the rotation center of the corner guard 300, and the buckle recess 302 extends in a direction close to the rotation center of the corner guard 300, and the locking portion 400 is provided with a lock 402 that engages with the buckle recess 302. Furthermore, mutually matching inclined surfaces are provided between the platform 301 and the lock 402, and when the folding member is rotated from the unfolded state to the folded state, the inclined surfaces between the platform 301 and the lock 402 interact with each other, so that the lock 402 first avoids the platform 301, and when the buckle recess 302 is aligned with the lock 402, the lock 402 is snapped into the buckle recess 302. It can be understood that the buckle 402 can avoid the platform 301 by utilizing its own material elasticity, or the lock 402 can be set as a rotating structure or a moving structure.

[0045] In some embodiments of the present invention, the locking portion 400 can be moved and adjusted, and the lock buckle 402 can be withdrawn from the buckling recess 302 as the locking portion 400 moves. In this way, it is only necessary to push the locking portion 400 to move so that the lock buckle 402 withdraws from the buckling recess 302, and the corner guard 300 can be expanded to cover the top corner of the box body 500 under the action of the first reset member 201 and the second reset member 202.

[0046] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the corner protection assembly further includes a third reset member 401, which acts on the locking portion 400 to limit the locking portion 400 from moving in the direction of the lock 402 exiting the buckle 302. In this embodiment, the third reset member 401 is provided to achieve automatic reset of the locking portion 400. It is understandable that the movement adjustment direction of the locking portion 400 can be flexibly set as needed, as long as it can move a certain distance and the corner protection portion 300 can be smoothly deployed.

[0047] In addition, the utility model provides a display screen, which includes a box body 500 and four corner protection components, and the four corner protection components are arranged at the four top corners of the box body 500. In the unfolded state, the corner protection part 300 covers the outside of the top corner of the box body 500, and in the folded state, the corner protection part 300 is concave relative to the surface of the box body 500 or remains flush with the surface of the box body 500.

[0048] In the display screen of the present utility model, by applying the above-mentioned corner protection assembly, when the folding part 200 is in the unfolded state, the corner protection part 300 can protect the corners of the box body 500. When the folding part 200 is in the folded state, the corner protection part 300 folds inward relative to the box body 500, which can not only protect the corners of the box body 500, improve the service life and splicing effect, but also retreat during assembly and will not hinder the assembly of the box body 500.

[0049] Referring to Figure 5 , specifically, in some embodiments, the front surface of the box body 500 is an LED display surface, and the four side walls of the box body 500 are provided with 45° chamfers so that when two box bodies 500 are joined, they form a 90° splice. Therefore, the top corner position of the box body 500 is a tapered structure. Installation platforms are provided at the positions corresponding to the four corners of the box body 500, and the four corner protection assemblies are correspondingly installed on the four installation platforms. One end of the corner protection part 300 facing away from the folding part is a splicing surface with the same angle as the corner plane of the box body 500. At the same time, the corner protection part 300 is provided with a protection surface matching the corner of the box body 500 at the front end of the platform 301. During application, the staff presses the locking part 400 to separate it from the corner protection part 300. Under the action of the first reset part 201 and the second reset part 202, the folding part flips forward and the corner protection part 300 extends forward until it abuts against the tapered corner of the box body 500. At this time, effective protection can be provided for the box body 500 during transportation, conveying, and storage. During assembly, the staff pushes the corner protection part 300 backward, which can drive the folding part to fold synchronously. During the pushing process, press inward until the locking part 400 snaps into the buckling recess 302 to complete the folding. At this time, the outer end surface of the corner protection part 300 is flush with the two inclined surfaces of the box body 500, which is convenient for splicing installation and can increase the force-bearing area between the two box bodies 500, thereby improving the splicing stability.

[0050] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Various changes can be made without departing from the gist of the present utility model within the knowledge scope of those of ordinary skill in the art to which the present utility model pertains. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
