Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an ultra-thin LED display screen cabinet structure, including a front frame 1, a rear shell 2 at the rear end of the front frame 1, a connecting post 3 on the surface of the rear shell 2, and a maintenance structure 4 on the surface of the rear shell 2.

[0025] The ultra-thin LED display screen is installed into the rear shell 2, and then the front frame 1 is connected to the rear shell 2 to protect the LED display screen.

[0026] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an ultra-thin LED display cabinet structure. The maintenance structure 4 includes an inspection frame 41. The inspection frame 41 is integrally formed on the surface of the back shell 2. An inspection cover 42 is mounted on the inspection frame 41. An installation structure 43 is provided on the side of the inspection frame 41.

[0027] The mounting structure 43 includes a fixing box 431. The fixing box 431 is fixed to the left and right sides of the inspection frame 41 by bolts. A knob 432 is rotatably connected to the rear end of the fixing box 431. A drive gear 433 is rotatably connected inside the fixing box 431, and the drive gear 433 is fixed to the knob 432.

[0028] The fixed box 431 is equipped with a slidingly connected toothed rod 434. The toothed rod 434 slides vertically up and down and is connected to the fixed box 431. A slider 438 is fixed on the surface of the toothed rod 434. The toothed rod 434 is meshed with the drive tooth 433.

[0029] Two fixing blocks 435 are integrally formed inside the fixed box 431 and located at the upper and lower ends of the middle part of the tooth rod 434. The fixing blocks 435 abut against the surface of the tooth rod 434, so that the sliding stability of the fixing blocks 435 is high. A positioning rod 436 is fixed on the fixing blocks 435. A spring 437 is assembled on the positioning rod 436. A sliding block 438 slides along the surface of the positioning rod 436. One end of the spring 437 is fixed on the surface of the lower fixing block 435, and the other end is connected to the surface of the sliding block 438.

[0030] The connecting teeth 439 are rotatably connected inside the maintenance frame 41 and are in meshing connection with the tooth rod 434. The middle part of the upper and lower ends of the maintenance frame 41 is assembled with the connecting teeth 439. The connecting teeth 439 are integrally formed with a connecting block 4310. The connecting block 4310 is provided with a clamping head 4311.

[0031] The connecting block 4310 is provided with a rotating opening 4313. The clamping head 4311 is located inside the rotating opening 4313. The clamping head 4311 cannot rotate counterclockwise through the limiting of the rotating opening 4313. The clamping head 4311 is rotatably connected to the connecting block 4310 through a torsional spring. The rear surface of the clamping head 4311 is an inclined surface. The maintenance cover 42 can be conveniently pressed down when being assembled into the maintenance frame 41, so that the clamping head 4311 rotates to achieve the beneficial effect of convenient installation of the maintenance cover 42. The maintenance cover 42 can be connected to the clamping head 4311.

[0032] The surface of the tooth rod 434 is integrally formed with a clamping strip 4312. The clamping strip 4312 is in close contact with the surface of the connecting teeth 439, so that the rotation of the connecting teeth 439 is more stable.

[0033] When the maintenance cover 42 is assembled into the maintenance frame 41, the maintenance cover 42 will press down the clamping head 4311. Under the action of the torsional spring, the clamping head 4311 resets and clamps the maintenance cover 42 to achieve the convenient installation of the maintenance cover 42. When the ultra-thin LED display screen needs to be maintained, the knob 432 is rotated to drive the driving teeth 433 to rotate. Since the tooth rod 434 is in meshing connection with the driving teeth 433, the tooth rod 434 will slide downward when the driving teeth 433 rotate, and then drive the connecting teeth 439 to rotate, thereby driving the connecting block 4310 to rotate the clamping head 4311 out of the maintenance cover 42, so as to release the limitation of the maintenance cover 42, and then the maintenance cover 42 is removed. The staff can maintain and repair the LED display screen through the maintenance frame 41 to achieve the beneficial effect of facilitating the subsequent maintenance and repair of the LED display screen.

[0034] The above merely describes preferred examples of the present application and is not intended to limit the present application, and although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
