One end of the second spring 17 is connected to the locking block 13, and the other end is connected to the base 12.

[0036] Please refer to further information. Figure 4-5 It is understood that the base 12 may include a base body 121, a first base protrusion 122, a second base protrusion 123, and a base connecting portion 124. The first base protrusion 122, the second base protrusion 123, and the base connecting portion 124 are connected to the base body 121. The base 12 may generally be stepped.

[0037] The base body 121 may be provided with a base groove 1211 and a base second through hole 1212. The base second through hole 1212 is provided on both sides of the base groove 1211. The base second protrusion 123 and the base connecting part 124 are provided in the base groove 1211. The base first protrusion 122 is provided on the base body 121.

[0038] The first protrusion 122 of the base may be provided with a first through hole 1221. The base connecting part 124 may be provided with a base fixing hole 1241, a base positioning block 1242, and a first spring limiting groove 1243. The base fixing hole 1241 is used to fix the entire corner protector 10, and the base positioning block 1242 is used to position the corner protector 10 on the LED display device 20.

[0039] The corner protector 11 is rotatably connected to the base 12 via the first shaft 14. Specifically, the first shaft 14 passes through the first through hole 1221 of the base.

[0040] The locking block 13 is rotatably connected to the base 12 via the second shaft 15. Specifically, the second shaft 15 passes through the second through hole 1212 of the base.

[0042] It is understandable that there can be two first protrusions 122 on the base. There can be two second protrusions 123 on the base. There can be two positioning blocks 1242 on the base.

[0043] Please refer to further information. Figure 6 It is understood that the locking block 13 may be provided with a pressing part 131 and a pressing connecting part 132. The pressing part 131 is connected to the pressing connecting part 132. The pressing connecting part 132 may be provided with a first protrusion 1321, a locking groove 1322, a second protrusion 1323, a locking through hole 1324, a second spring limiting groove 1325, and a pressing connecting part body 1326.

[0044] The first protrusion 1321 of the locking block connects to the main body 1326 of the pressing connector. The locking block groove 1322 is located at the bottom of the main body 1326 of the pressing connector, and the locking block groove 1322 is located on the side of the first protrusion 1321 of the locking block. The second protrusion 1323 and the through hole 1324 of the locking block are located on the first protrusion 1321 of the locking block. The second spring limiting groove 1325 is located on the main body 1326 of the pressing connector.

[0045] Understandably, the pressing connection 132 extends into the base groove 1211. The second shaft 15 passes through the base second through hole 1212 and the locking block through hole 1324. The second spring 17 is located in the locking block groove 1322. One end of the second spring 17 is connected to the first spring limiting groove 1243, and the other end is connected to the second spring limiting groove 1325. The second spring 17 allows the locking block 13 to return to its original position after being pressed. The base second protrusion 123 cooperates with the locking block second protrusion 1323 to limit the rotation angle of the locking block 13.

[0046] Please refer to further information. Figure 1-2 and Figure 7It is understood that the corner protector 11 may include a corner protector body 111, a corner protector connecting part 112, and a buffer block 113. The corner protector connecting part 112 and the buffer block 113 are connected to the corner protector body 111. The corner protector body 111 may include a buffer block fixing groove 1111 and a slot 1112. The buffer block fixing groove 1111 is used to fix the buffer block 113.

[0047] The corner protector connecting part 112 may include a corner protector connecting part body 1121, a first corner protector protrusion 1122, and a second corner protector protrusion 1123. The first corner protector protrusion 1122 and the second corner protector protrusion 1123 are connected to the corner protector connecting part body 1121. The first corner protector protrusion 1122 may have a first corner protector through hole 11221. The second corner protector protrusion 1123 may have a second corner protector through hole 11231 and a spring connecting hole 11232.

[0048] Understandably, the first shaft 14 passes through the first through hole 1221 of the base, the first through hole 11221 of the corner protector, and the second through hole 11231 of the corner protector. The first spring 16 is located between the first protrusion 1122 and the second protrusion 1123 of the corner protector. One end of the first spring 16 is connected to the spring connecting hole 11232, and the other end is connected to the base 12. The first spring 16 can restore the corner protector 11 to its original position.

[0049] Please refer to further information. Figure 8 It is understandable that when the corner protector 10 does not need to protect the LED display device 20, the slot 1112 abuts against the slot 1322, the slot 13 fixes the corner protector 11, and the first spring 16 is compressed.

[0050] When protection of the LED display device 20 is required, pressing the pressing part 131 causes the locking block 13 to rotate around the second axis 15, compressing the second spring 17. The locking groove 1112 disengages from the locking block groove 1322, and the corner protector 11 rotates around the first axis 14 under the drive of the first spring 16. When pressure is no longer applied to the pressing part 131, the second spring 17 drives the locking block 13 to return to its original position.

[0051] Please refer to further information. Figure 9-10 It is understood that the corner protector 10 is connected to the LED display device 20. Specifically, the corner protector 10 is located at the corner of the LED display device 20. The LED display device 20 has a corner protector connection hole corresponding to the base fixing hole 1241, and a corner protector positioning hole corresponding to the base positioning block 1242.

[0052] This application improves efficiency by designing a corner protector 10 for a display screen, which facilitates the installation and removal of the corner protector 10 on the LED display screen device 20.

[0053] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
