[0037] In the embodiment, the front side of the left and right inner side walls of the storage cavity 11 is symmetrically provided with a first sliding groove 14 arranged in the vertical direction, and the left and right sides of the bottom of the display board 20 are respectively fixedly provided with a connecting plate 21, and the side away from each other of the two connecting plates 21 is fixedly provided with a sliding block 22 slidably embedded in the first sliding groove 14.

[0038] In the embodiment, the top of the rear wall of the two first sliding grooves 14 is provided with a second sliding groove 15 arranged in the horizontal direction, and the two sliding blocks 22 can be slidably embedded in the corresponding second sliding groove 15, and the bottom of the display board 20 is rotatably connected with the top of the output end of the electric push rod 13.

[0039] In the embodiment, two ends of the two rotating shafts 31 extend to the outside of the frame body 10, and the left and right outer walls of the frame body 10 are respectively fixedly provided with sleeves 16 on the outer periphery of the corresponding rotating shaft 31. The outer walls of the two rotating shafts 31 are respectively sleeved with coil springs 50, and the two ends of the coil springs 50 are respectively connected to the outer wall of the corresponding rotating shaft 31 and the inner wall of the corresponding sleeve 16.

[0040] In the embodiment, the limiting assembly includes limiting units symmetrically arranged on the left and right sides of the top of the frame body 10. The limiting unit includes a limiting block 41 fixedly arranged on the top of the frame body 10. The bottom of the front and rear walls of the limiting block 41 is symmetrically provided with a groove 42. The top wall of the groove 42 is slidably provided with a limiting rod 43. The bottom of the limiting rod 43 has a magnetic force, and the bottom of the limiting rod 43 is magnetically connected to the top of the frame body 10.

[0041] In the embodiment, the bottoms of the two limiting rods 43 of each limiting unit away from each other are respectively provided with a guide and push inclined surface 431.

[0042] In the embodiment, the bottom of the frame body 10 is fixedly provided with a walking wheel 60 with a locking mechanism at each corner.

[0043] The specific implementation process is as follows:

[0044] In the initial state (i.e., use state one), the display board 20 is located in the storage cavity 11. The two connecting rods 33 are respectively connected to the frame body 10 through the limiting assembly. The two curtains 32 of the shielding assembly cover the opening 12 of the storage cavity 11. When display is needed, the limiting assembly is loosened and the rotating shaft 31 is rotated to wind the curtain 32 to open the opening 12. The electric push rod 13 is extended to lift the display board 20 (i.e., use state two). When display needs to be paused, the electric push rod 13 is retracted to move the display board 20 downward into the storage cavity 11. Then the two connecting rods 33 are pulled to again open the curtain 32 to shield the opening 12.

[0045] In the initial state, the sliding block 22 is in contact with the bottom wall of the first sliding groove 14. When the electric push rod 13 is extended, the first sliding groove 14 prevents the display board 20 from rotating, so that the display board 20 moves upward with the extension of the electric push rod 13. When the sliding block 22 comes into contact with the top wall of the first sliding groove 14, the sliding block 22 cannot continue to move upward. As shown in use state three, the electric push rod 13 is continuously extended. At this time, the second sliding groove 15 pushes the sliding block 22 to move horizontally, thereby pushing the display board 20 to rotate.

[0046] When the curtain 32 is extended and the rotating shaft 31 is rotated, the coil spring 50 will be deformed and have an elastic force. After the limiting assembly is loosened, the elastic force of the coil spring 50 drives the rotating shaft 31 to reset, and at the same time, the curtain 32 is wound.

[0047] When the curtain 32 is stretched, the connecting rod 33 moves towards the direction close to the groove 42, and the connecting rod 33 contacts the guide and push inclined surface 431 of the limiting rod 43, and first pushes the limiting rod 43 to move upwards, and when the connecting rod 33 completely passes the limiting rod 43, the limiting rod 43 resets downwards, and at this time, the connecting rod 33 in the groove 42 cannot push the limiting rod 43 upwards.

[0048] The above is only the embodiment of the present application, and the well-known specific technical solutions or common knowledge in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
