Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , comprising an external component 100, an extension component 200 and a standing component 300.

[0031] The external component 100 includes an upper display board 110. In order to fix the device at a certain height when it is unfolded, a locking block 130 is fixed to the side wall of the upper display board 110 by screws. The inner wall of the locking block 130 is connected with a bolt 150 by embedding. The bottom of the upper display board 110 is connected with the lower display board 120 by fitting. In order to make the device more stable when in use, a three-ply plate 140 is fixed to the side wall of the lower display board 120 by welding.

[0032] In order to enable the device to be unfolded and supported, the extension component 200 includes an extension arm 1 210 connected to the inner wall of the upper extension plate 110 by embedding, and the inner wall of the lower extension plate 120 is connected to the extension arm 220 by embedding. In order to connect the extension arm 1 210 and the extension arm 220, the middle section of the side wall of the extension arm 1 210 and the extension arm 220 is integrally formed with a connecting shaft hole 290, and the circumferential inner wall of the connecting shaft hole 290 is embedded with a connecting shaft 230, and the side wall of the connecting shaft 230 is fixed with a shaft sleeve 240 by welding. The connecting shaft 230 passes through the connecting shaft hole 290 in the middle section of the side wall of the extension arm 1 210 and the extension arm 220 and is connected to the shaft sleeve 240. In order to facilitate the extension of the arm The first and second extension arms 210 and 220 are extended, the side walls of the first and second extension arms 210 and 220 are integrally formed with roller holes 250, the circumferential inner wall of the roller hole 250 is embedded with a roller shaft 270, the circumferential outer wall of the roller shaft 270 is embedded with a roller 260, the side wall of the roller shaft 270 is fixed with a wheel sleeve 280 by welding, the roller shaft 270 passes through the side wall of the roller 260 and the roller hole 250 and is connected with the wheel sleeve 280, in order to facilitate the rolling of the roller 260, the side wall of the upper exhibition board 110 is integrally formed with an upper slide groove 291, and the side wall of the lower exhibition board 120 is integrally formed with a lower slide groove 292;

[0033] The sign assembly 300 includes a base plate 310 fixed to the top of the upper display plate 110 by screws. In order to fix the sign, a fixing plate 320 is fixed to the top of the base plate 310 by welding. In order to connect the fixing plate 330, a slide groove 350 is left at the top of the base plate 310 by integral molding. The inner wall of the slide groove 350 is embedded with a slider 340. The top of the slider 340 is fixed with a movable plate 330 by welding. In order to adjust the distance between the movable plate 330 and the fixed plate 320, an adjustment plate 360 ​​is fixed to the top of the base plate 310 by welding. The side wall of the adjustment plate 360 ​​is left with a threaded hole 391 by integral molding. The circumferential inner wall of the threaded hole 391 is connected with an adjusting screw 370 by threading.

[0034] Working principle: When using the device, by pulling the handle 160, the upper display plate 110 moves upward, driving the roller 260 to slide in the upper slide groove 291 and the lower slide groove 292, so that the display arm 1 210 and the display arm 220 are staggered and unfolded through the connecting shaft 230. After unfolding to a suitable height, the device is fixed by lowering the bolt column 150 in the locking block 130, and the identification plate is placed in the gap between the fixed plate 320 and the movable plate 330. By rotating the adjusting screw 370 on the adjusting plate 360, the fixed plate 320 moves, and the adjusting screw 370 pushes the movable plate 330 to move. The movable plate 330 drives the slider 340 to move in the slide groove 350 on the box fixed plate 320, so that the movable plate 320 and the fixed plate 330 clamp and fix the identification plate, and by rotating the adjusting screw 370 in the opposite direction, the gap between the movable plate 320 and the fixed plate 330 becomes larger, so that the identification plate can be replaced.

[0035] Furthermore, in order to avoid wear and paint peeling caused by contact between the identification plate, the fixed plate 320 and the movable plate 330, and to avoid wear of the side wall of the movable plate 330 by the adjusting screw 370, specifically, the side walls of the fixed plate 320 and the movable plate 330 are fixed with rubber pads 390 by gluing, and the side walls of the adjusting screw 370 are fixed with contact plates 380 by gluing.

[0036] Next, in order to increase the adjustable height and facilitate the storage of the bolt 159, specifically, the number of the locking blocks 130 is four, and the side walls of the locking blocks 130 are integrally formed with gaps.

[0037] It is worth noting that in order to reduce the rolling noise of the roller 260 on the upper slide groove 291 and the lower slide groove 292 , specifically, the circumferential outer wall of the roller 260 is connected with a rubber ring by nesting.

[0038] In addition, in order to ensure the stability of the unfolding process of the first and second arms 210 and 220, the side walls at both ends of the first and second arms 210 and 220 are provided with two rollers 260, and in order to facilitate the lifting and unfolding of the device, specifically, the side walls of the upper display panel 110 are integrally formed with handles 160.

[0039] Finally, in order to maintain the stability of the device, the length and material of the first arm 210 and the second arm 220 are consistent, and in order to ensure the supporting force of the device after it is unfolded, specifically, the first arm 210 and the second arm 220 are connected in an X-shape through the connecting shaft 230.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
