DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1 , Figure 2 and Figure 3 An electronic public display screen shown includes a plurality of display screens 1 distributed from top to bottom and a pair of support rods 2 arranged on one side of the display screens 1, the bottom ends of the pair of support rods 2 are connected by a base, and a first clamping frame 3 and a second clamping frame 4 are provided on the display screens 1. In a natural state, the pair of support rods 2 are located in the accommodating space formed by the first clamping frame 3 and the second clamping frame 4, and the first clamping frame 3 and the second clamping frame 4 are respectively attached to the surface of the support rods 2.

[0024] The first clamping frame 3 can move laterally. When the first clamping frame 3 moves away from the second clamping frame 4 to a limit, a space is formed between the first clamping frame 3 and the second clamping frame 4 to accommodate a pair of support rods 2 passing through.

[0025] like Figure 2 , Figure 3As shown, the display screen 1 is provided with a guide frame 5, the inner side of the guide frame 5 is provided with a transversely distributed guide rod 6, the first clamping frame 3 is provided with a follower ring 7, the follower ring 7 is sleeved on the guide rod 6, when the first clamping frame 3 moves away from the second clamping frame 4, the follower ring 7 moves along the distribution direction of the guide rod 6. The distance between the first clamping frame 3 and the second clamping frame 4 is enlarged to accommodate a pair of support rods 2 to be smoothly placed.

[0026] In this process, there is no need to perform positioning and installation operations at multiple points on the display screen 1, and the display screen 1 can be quickly aligned with the support rod 2 to maintain the stable state of the display screen 1 during the installation operation. Multiple display screens 1 can be quickly installed to a specified height on the support rod 2. The display screen 1 can be flexibly installed and disassembled according to actual work needs, which has the advantage of portable operation.

[0027] like Figure 2 , Figure 3 As shown, when the display screen 1 is moved to the designated position and is working, in order to avoid the first clamping frame 2 from being offset, the tightness of the first clamping frame 3, the second clamping frame 4 and the support rod 2 is maintained. A clamping ring 8 coaxially distributed with the follower ring 7 is provided on the guide rod 6, and a rotatable limit pin 9 is provided on the clamping ring 8. The limit pin 9 is vertically distributed with the guide rod 6. When the limit pin 9 is rotated toward the guide rod 6 to the limit position, the end of the limit pin 9 abuts against the surface of the guide rod 6. At this time, the clamping ring 8 is tightly pressed against the surface of the guide rod 6, preventing the follower ring 7 and the first clamping frame 3 from moving away from the second clamping frame 4 again, maintaining the stability of the first clamping frame 3 and the second clamping frame 4, and preventing the first clamping frame 3 and the second clamping frame 4 from being separated from the support rod 2, thereby improving the safety of the display screen 1 in the working state.

[0028] like Figure 3 As shown, a rotatable support block 10 is provided under the first card frame 3 and the second card frame 4, and the support block 10 is an L-shaped structure. In a natural state, in order to prevent the first card frame 3 and the second card frame 4 from sliding down and ensure the stability of the display screen 1 at a specified height, a pair of support rods 2 are respectively attached to the inner right-angled sides of a pair of support blocks 10.

[0029] like Figure 4 , Figure 5 As shown, a pair of support rods 2 are connected by a plurality of cross beams 11 distributed from top to bottom, a pair of limit shafts 12 are provided on the cross beams 11 , and the support blocks 10 are sleeved on the limit shafts 12 .

[0030] The surface of the limit shaft 12 is threadedly connected with a pressure ring 13 and a stop ring 14. In a natural state, the pressure ring 13 abuts against the surface of the bracket 10, and the stop ring 14 is provided at one end of the limit shaft 12 away from the bracket 10. When the pressure ring 13 moves toward the stop ring 14, a space is left for the bracket 10 to move along the distribution direction of the limit shaft 12, and the bracket 10 can be away from the support rod 2. Subsequently, the bracket 10 can be operated to rotate, and the interception force generated by itself under the first clamping frame 3 and the second clamping frame 4 is released, leaving space for the first clamping frame 3 and the second clamping frame 4 to move along the distribution direction of the support rod 2.

[0031] Through the above operation, the height of the first clamping frame 3 and the second clamping frame 4 on the support rod 2 can be easily adjusted to achieve the purpose of adjusting the height of the display screen 1. In this process, there is no need to repeatedly operate the first clamping frame 3 and the second clamping frame 4 to separate from the support rod 2. The height adjustment operation can be directly performed on the support rod 2, which improves the portability during the operation.

[0032] like Figure 4 , Figure 5 As shown, in order to facilitate the operation of the clamping ring 8 to move and reduce the inconvenience of the staff operating on the inner side of the guide frame 5, the clamping ring 8 is protruded outward to form a support leg 15, and the first clamping frame 3 is provided with a channel that can accommodate the lateral sliding of the support leg 15, and the support leg 15 passes through the channel and extends to the inner side of the first clamping frame 3. When the clamping ring 8 is stuck, the support leg 15 can be operated to quickly operate the clamping ring 8 on the inner side of the guide frame 5 to move.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
