DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods as needed.

[0028] Reference Figure 1 、 Figure 3-Figure 6The embodiment of the present utility model discloses an LED display screen with an anti-slip function, comprising a display module 100, a housing 200 and an anti-slip mechanism. A plurality of anti-slip mechanisms are provided between the display module 100 and the housing 200 to improve the stability and reliability of the anti-slip mechanism in supporting the display module 100. Specifically, the anti-slip mechanism comprises a hook 300 provided on the display module 100 and a limiting assembly 400 provided on the housing 200. The limiting assembly 400 comprises a slide bar 420 provided on the housing 200 and an anti-slip block 430 provided at the end of the slide bar 420. The hook 300 is provided with a U-shaped groove 310 with a downward opening. When the display module 100 is installed, the display module 100 moves downward so that the U-shaped groove 310 on the hook 300 is forked on the slide bar 420. The slide bar 420 is slidably connected to the U-shaped groove 310. The slide bar 420 supports the hook 300 and the display module 100. In addition, the size of the anti-slip block 430 is larger than the size of the U-shaped groove 310, and the anti-slip block 430 is a circular block, that is, the diameter of the anti-slip block 430 is larger than the groove width of the U-shaped groove 310, so that when the slide bar 420 slides relative to the U-shaped groove 310, the slide bar 420 is prevented from separating from the U-shaped groove 310, and the display module 100 is prevented from separating from the box body 200. In this way, when the installation and fixing structure (magnetic structure) between the display module 100 and the box body 200 fails, the slide bar 420 can support the display module 100, and the anti-slip block 430 prevents the display module 100 from separating from the box body 200, thereby avoiding the risk of the display module 100 falling off.

[0029] In some embodiments, reference Figure 4-Figure 5 、 Figure 7 The housing 200 is provided with a guide hole 410, and the slide bar 420 is slidably connected to the guide hole 410. A limit ring 440 is provided at the end of the slide bar 420 away from the anti-slip block 430. When the slide bar 420 moves in the guide hole 410, the limit ring 440 prevents the slide bar 420 from disengaging from the guide hole 410. When installing the display module 100, the slide bar 420 is slid toward the display module 100 so that the hook 300 is engaged with the slide bar 420. The slide bar 420 can be moved in the opposite direction to pull the display module 100 toward the housing 200, thereby achieving a magnetic connection between the display module 100 and the housing 200. Alternatively, the display module 100 can be directly moved, and when the display module 100 moves, the slide bar 420 will slide in the guide hole 410, thereby achieving a magnetic connection between the display module 100 and the housing 200.

[0030] In a preferred embodiment, the retaining ring 440 is detachably connected to the end of the slide rod 420 via a first screw 450, thereby facilitating installation and removal of the retaining ring 440. Specifically, the retaining ring 440 is provided with a connecting hole 480, and the end of the slide rod 420 is provided with a first threaded hole 470 along its axis. The first screw 450 is a countersunk screw that passes through the connecting hole 480 and is locked in the first threaded hole 470, thereby achieving installation of the retaining ring 440.

[0031] Furthermore, the guide hole 410 is in the shape of a stepped hole, which includes a first guide hole 410 and a second guide hole 410, and the diameter of the first guide hole 410 is smaller than the diameter of the second guide hole 410, and the first guide hole 410 is set toward the display module 100, the sliding rod 420 is slidably connected to the first guide hole 410, and the limiting ring 440 is located in the second guide hole 410, and the diameter of the limiting ring 440 is larger than the diameter of the first guide hole 410 and smaller than the diameter of the second guide hole 410, so that when the sliding rod 420 slides toward the display module 100, the step at the connection between the first guide hole 410 and the second guide hole 410 blocks the limiting ring 440, thereby preventing the sliding rod 420 from disengaging from the guide hole 410.

[0032] In some embodiments, reference Figure 4 and Figure 5 A sealing ring 460 is provided on the sliding rod 420, and the sealing ring 460 and the second guide hole 410 are slidably sealed, thereby preventing debris from entering the first guide hole 410 from the second guide hole 410 and affecting the sliding stability between the sliding rod 420 and the first guide hole 410.

[0033] In some embodiments, the roughness of the inner wall of the second guide hole 410 on the side close to the first guide hole 410 is greater than the roughness of the other side. When the sealing ring 460 moves with the sliding rod 420 to the side of the second guide hole 410 close to the first guide hole 410, the sealing ring 460 no longer moves with the sliding rod 420. In this way, when the sliding rod 420 moves, a relative position is generated between the sliding rod 420 and the sealing ring 460. The sealing ring 460 generates friction on the sliding rod 420, which has a slight damping effect on the movement of the sliding rod 420.

[0034] In some embodiments, reference Figure 2The hook 300 includes a supporting portion and a connecting portion. The U-shaped groove 310 is provided on the connecting portion. The supporting portion is detachably connected to the display module 100 through a second screw 330. Specifically, a second threaded hole 110 is provided on the display module 100, and a countersunk hole 320 is provided on the supporting portion. The second screw 330 is a hexagon socket head screw. The second screw 330 is passed through the countersunk hole 320 and locked in the second threaded hole 110, thereby achieving fixed installation of the hook 300 and the display module 100, and also facilitating the disassembly operation of the hook 300.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
