Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a locking structure for an LED display screen. Background Art

[0002] An LED display screen is a flat panel display device used to display information such as text and images. Its main structure includes an LED display screen module and a protective housing. When the LED display screen is in use, the protective housing is used to protect the LED display screen module.

[0003] In some existing LED display screens, the LED display screen module and the protective housing are fixed by multiple groups of screws, which can ensure the firm connection between the LED display screen module and the protective housing and prevent the stability of the LED display screen from being affected by external vibration or movement. However, when repairing the LED display screen module, auxiliary tools are required to disassemble multiple groups of screws, and then the LED display screen module is removed for repair. After the repair is completed, multiple groups of screws are used to fix the LED display screen module and the protective housing again. In this process, the disassembly and assembly of multiple groups of screws are time-consuming, which makes the repair of the LED display screen module inconvenient. Therefore, we propose a locking structure for an LED display screen. Summary of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0028] Embodiment 1

[0029] Please refer to Figure 1-8 , the present utility model provides a technical solution:

[0030] An LED display locking structure, including a protective shell 1 and a display body 2, further comprising:

[0031] A card slot 3, which is opened on the outer surface of the display body 2, and there are two card slots 3;

[0032] A limiting mechanism 4, which is arranged on the inner surface of the protective shell 1 and is used for the quick fixation of the display body 2 and the release of the fixed state. The two card slots 3 are inserted into the limiting mechanism 4;

[0033] A positioning mechanism 5, which is slidably connected to the inner surface of the protective shell 1 and is used for the positioning and pressing of display bodies 2 with different thicknesses. The positioning mechanism 5 is in contact with the display body 2.

[0034] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the limiting mechanism 4 includes a plurality of springs 41 arranged on the inner surface of the protective shell 1, and the plurality of springs 41 are evenly distributed. One end of the spring 41 is provided with a connecting block 42. A limiting rod 43 is arranged on the outer surface of the connecting block 42 close to the spring 41. The plurality of limiting rods 43 are all slidably connected to the protective shell 1. The spring 41 is sleeved on the outer surface of the limiting rod 43. One end of the two limiting rods 43 is provided with a connecting plate 44. A limiting plate 45 is arranged on the outer surface of the connecting plate 44 close to the limiting rod 43. The limiting plate 45 is inserted into the card slot 3. A pushing mechanism 46 is slidably connected to the inner surface of the protective shell 1.

[0035] Specifically, as Figure 3 and Figure 4 shown, the pushing mechanism 46 includes a push block 461 slidably connected to the inner surface of the protective shell 1. Two connecting blocks 462 are symmetrically arranged on the outer surface of the push block 461. A connecting rod 463 is arranged on the outer surface of the connecting block 462. The connecting rod 463 is fixedly connected to the connecting block 42 close to the push block 461.

[0036] Specifically, as Figure 6 shown, an inclined groove 6 is opened on the outer surface of the limiting plate 45. When the display body 2 contacts the limiting plate 45, the limiting plate 45 can move outward towards the display body 2 under force, thereby facilitating the installation of the display body 2.

[0037] Specifically, as Figure 1 、 Figure 3 、 Figure 7 and Figure 8As shown in the figure, the positioning mechanism 5 includes a second limiting rod 51 slidably connected to the inner surface of the protective shell 1. There are two second limiting rods 51. One end of the two second limiting rods 51 is provided with a pressing plate 52. The pressing plate 52 is in contact with the display screen body 2. An adjusting mechanism 53 is provided on the outer surface of the pressing plate 52 away from the display screen body 2.

[0038] Specifically, as Figure 3 , Figure 7 and Figure 8 shown, the adjusting mechanism 53 includes a threaded sleeve 531 provided on the outer surface of the pressing plate 52. A threaded rod 532 is threadedly connected to the inner surface of the threaded sleeve 531. The threaded rod 532 is rotatably connected to the protective shell 1. A rotating block 533 is provided at one end of the threaded rod 532 away from the threaded sleeve 531.

[0039] Working principle: When performing maintenance on the electronic components on the display screen body 2, push the push block 461. The movement of the push block 461 drives the second connecting block 462 to move in the opposite direction. Then, the movement of the second connecting block 462 in the opposite direction drives the connecting rod 463 to move in the opposite direction, thereby driving the connecting plate 44 to move in the opposite direction. Then, the movement of the connecting plate 44 in the opposite direction drives the limiting plate 45 to move in the opposite direction, separating it from the card slot 3 on the display screen body 2 and releasing the limiting state of the display screen body 2. Thus, the display screen body 2 can be removed from the protective shell 1 to perform maintenance on the electronic components on the display screen body 2. During this process, the connecting plate 44 is limited by the first limiting rod 43 to ensure stable movement of the connecting plate 44;

[0040] After the maintenance is completed, insert the display screen body 2 into the protective shell 1. When the display screen body 2 contacts the limiting plate 45, the limiting plate 45 is forced to move outward from the display screen body 2. When the display screen body 2 contacts the pressing plate 52, due to the elastic force of the spring 41, the first connecting block 42 moves. Then, the movement of the first connecting block 42 drives the first limiting rod 43 to move, thereby driving the connecting plate 44 to move. Then, the movement of the connecting plate 44 drives the limiting plate 45 to move, inserting it into the card slot 3 on the display screen body 2 to limit the display screen body 2, thereby completing the position fixing of the display screen body 2;

[0041] When the thickness of the used display screen body 2 is different, rotate the rotating block 533. The rotation of the rotating block 533 drives the threaded rod 532 to rotate. Then, the rotation of the threaded rod 532 drives the threaded sleeve 531 to move, thereby driving the pressing plate 52 to move to a suitable position to position and press the display screen body 2 with different thicknesses. During this process, the pressing plate 52 is limited by the second limiting rod 51 to ensure stable movement of the pressing plate 52.

[0042] Embodiment 2

[0043] Please refer to Figure 9 , the present utility model provides a technical solution:

[0044] Different from Embodiment 1, two buffer pads 7 are symmetrically arranged on the outer surface of the connecting plate 44, and a plurality of buffer pads 7 are all in contact with the protective shell 1.

[0045] Through the arrangement of the buffer pads 7, when the connecting plate 44 and the limiting plate 45 move towards the display body 2, the buffer pads 7 can buffer and damp the limiting rod 1, the connecting plate 44 and the limiting plate 45, thereby ensuring the stability of the structural connection.
