[0006] Furthermore, the driving assembly includes a turntable and a guide groove; the turntable is rotatably mounted on the rear surface of the display module and is provided with an eccentric slide groove; the guide groove is provided on the rear surface of the display module, with the outer end facing the positioning flange and the inner end facing the turntable; the pressure rod is movably inserted in the guide groove, and the inner end of the pressure rod is hinged to the eccentric slide groove, and the turntable is rotated to make the outer end of the pressure rod extend out of or retract into the outer end of the guide groove.

[0007] Furthermore, the driving assembly also includes a U-shaped handle, and both ends of the U-shaped handle are hinged to the side surfaces of the turntable.

[0008] Furthermore, a positioning protrusion is provided on the bottom surface of the U-shaped handle, and a positioning groove is provided on the rear surface of the display module; when in the locked state, the U-shaped handle is flipped so that the bottom surface of the U-shaped handle is close to the rear surface of the display module, the positioning protrusion is embedded in the positioning groove, and the turntable and the display module are positioned relative to each other.

[0009] Furthermore, the outer end of the pressure rod is a step structure.

[0010] By adopting the above technical scheme, the beneficial effect of the present invention is that the driving component drives the pressure rod to move, so that the outer end of the pressure rod presses the rear surface of the locking flange, thereby locking the display module, which can prevent the display module from falling, does not affect the internal layout of the display module, and facilitates the installation and removal of the display module.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, an embodiment of the present invention provides an anti-falling structure for an LED display module, comprising a box frame 10 and a display module 20 , wherein the rear surface edge of the display module 20 is mounted on the front surface of the box frame 10 .

[0019] like Figures 2~4 As shown, the inner wall of the box frame 10 is provided with a locking flange 11, and the front surface of the locking flange 11 is closely attached to the rear surface of the display module 20. The rear surface of the display module 20 is provided with a pressing rod 30 and a driving assembly 40, and the driving assembly 40 drives the pressing rod 30 to move, so that the outer end of the pressing rod 30 is pressed against or away from the rear surface of the locking flange 11.

[0020] like Figure 3 As shown, in the locked state, the outer end of the pressing rod 30 presses the rear surface of the locking flange 11, and the display module 20 is locked and connected with the box frame 10. That is, the outer end of the pressing rod 30 and the rear surface of the display module 20 clamp the locking flange 11 of the box frame 10, thereby achieving a locked connection.

[0021] like Figure 4 As shown, in the unlocked state, the outer end of the pressing rod 30 is away from the rear surface of the locking flange 11, and the display module 20 is released from the locked connection with the box frame 10. That is, the outer end of the pressing rod 30 and the rear surface of the display module 20 release the clamping of the locking flange 11 of the box frame 10, thereby releasing the locked connection.

[0022] like Figures 2~4 As shown, the driving assembly 40 includes a turntable 41 and a guide slot 42. The turntable 41 is rotatably mounted on the rear surface of the display module 20 and is provided with an eccentric slide slot 43. The guide slot 42 is provided on the rear surface of the display module 20, with the outer end facing the locking flange 11 and the inner end facing the turntable 41. The pressure rod 30 is movably inserted in the guide slot 42, and the inner end of the pressure rod 30 is hinged to the eccentric slide slot 43.

[0023] The turntable 41 is rotated to make the outer end of the pressing rod 30 extend out of the outer end of the guide groove 42 and press the rear surface of the locking flange 11, thereby entering the locked state. Alternatively, the turntable 41 is rotated in the opposite direction to make the outer end of the pressing rod 30 retract into the outer end of the guide groove 42 and away from the rear surface of the locking flange 11, thereby entering the unlocked state.

[0024] like Figure 1~2 As shown, the driving assembly 40 further includes a U-shaped handle 44, and both ends of the U-shaped handle 44 are hinged to the sides of the turntable 41. The operator can rotate the turntable 41 by twisting the U-shaped handle 44, thereby controlling locking or unlocking.

[0025] like Figure 1~2 As shown, the bottom surface of the U-shaped handle 44 is provided with a positioning protrusion (not shown in the figure), and the rear surface of the display module 20 is provided with a positioning groove 45. In the locked state, the U-shaped handle 44 is flipped so that the bottom surface of the U-shaped handle 44 is close to the rear surface of the display module 20, the positioning protrusion is embedded in the positioning groove 45, and the turntable 41 and the display module 20 are mutually positioned. The turntable 41 and the display module 20 are mutually positioned, which can prevent the pressure rod 30 from being away from the rear surface of the locking flange 11 due to vibration or gravity, and realize the anti-loosening function.

[0026] like Figure 3~4 As shown, the outer end of the pressure rod 30 is a step structure. In the locked state, the positioning flange 11 is embedded in the step structure of the outer end of the pressure rod 30, which can not only achieve the compression of the rear surface of the positioning flange 11, but also limit the extension length of the pressure rod 30 to achieve the anti-fool function.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
