Based on the embodiments in the present utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 It can be known that the present utility model provides a technical scheme: a display stand capable of being extracted and expanded, comprising: a moving frame 1, a support plate 2 and a display board 3, the top of the moving frame 1 is provided with the support plate 2, the surface of the support plate 2 is connected with the display board 3, the back of the display board 3 is connected with a connecting frame 4, the inside of the connecting frame 4 is provided with a through slot 5, the inside of the through slot 5 is slidably connected with a sliding rod 6, the rear ends of the two sliding rods 6 are commonly connected with a connecting plate 7, the front ends of the two sliding rods 6 are commonly connected with an expansion plate 9, the inside of the connecting plate 7 is threadedly connected with a screw knob 8, one side of the expansion plate 9 close to the display board 3 is connected with a moving block 10, the inside of the display board 3 close to the moving block 10 is connected with a positioning column 11, the two connecting frames 4 are commonly connected with a support column 12, and the connecting frame 4 close to the support plate 2 is connected with the support plate 2 surface through the support column 12 with different sizes, the moving block 10 and the moving frame 1 form a sliding structure, the inside of the moving block 10 is provided with a through hole with a size matched with the positioning column 11, and the inside of the connecting frame 4 is provided with a threaded hole with a size matched with the screw knob 8.

[0024] In specific implementation, the display stand is relatively common in engineering cost, and the staff can write the required data on the display board 3, thereby facilitating the staff to count and check the data, the size of the traditional display board 3 is relatively fixed, which leads to the difficulty in writing more content on the display board 3, and the practicability is relatively low, the two connecting plates 7 can be pulled away from each other, when the connecting plate 7 moves, it can drive the two sliding rods 6 to slide in the corresponding through slot 5, and when the connecting plate 7 moves, it can drive the screw knob 8 to move, when the two sliding rods 6 slide, it can drive the expansion plate 9 to move, when the expansion plate 9 moves, it can drive the moving block 10 to move, when the two sliding rods 6 move to the maximum distance, the expansion plate 9 can be extracted from the gap between the connecting frame 4 and the display board 3, at this time, the connecting plate 7 can be pushed towards the connecting frame 4, when the connecting plate 7 moves, it can drive the sliding rod 6 and the expansion plate 9 to move, when the front surface of the expansion plate 9 moves to the position flush with the front surface of the display board 3, the expansion plate 9 can drive the moving block 10 to be sleeved outside the positioning column 11, and the screw knob 8 is tightened, when the screw knob 8 is tightened, the end thereof can be threadedly penetrated through the connecting frame 4, thereby fixing the position of the expansion plate 9.

[0025] Please refer toFigures 1-4 It can be seen that the writing area of ​​the display board 3 can be expanded by the two sets of expansion boards 9, so that staff can write more content on the display board 3 and expansion boards 9, thereby facilitating staff to perform statistics and verification of data and improving the practicality of the display stand.

[0026] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that the bottom of the support plate 2 is connected to the adjusting rod 13, the inside of the adjusting rod 13 is provided with a slot 14, the inner side of the movable frame 1 is connected to the fixing block 15, the inside of the two fixing blocks 15 is slidably connected to the T-shaped block 16, the two T-shaped blocks 16 are connected to the rack plate 17, the end of the rack plate 17 near the adjusting rod 13 is connected to the plug block 18, the two fixing blocks 15 are connected to the connecting seat 19, the inside of the connecting seat 19 is connected to the rotating rod 20 through the bearing, the outside of the rotating rod 20 is connected to the gear 21, the gear 21 and the two sets of rack plates 17 form a meshing structure, and the two sets of rack plates 17 are obliquely symmetrically distributed.

[0027] In practice, the overall structure of the display frame is usually quite simple, and the height of traditional display frames is fixed, making it difficult for staff to adjust the height of the display panel 3 according to their own needs and actual conditions. This makes the display panel 3 inconvenient to use. Before using the display panel 3, the support plate 2 can be lifted upwards. When the support plate 2 moves, it can drive the display panel 3 and the adjusting rod 13 to move. When the adjusting rod 13 moves, it can slide with the moving frame 1. When a set of slots 14 on a set of adjusting rods 13 are completely removed from the corresponding moving frame 1, the display panel 3 can rise to the specified height. At this time, the rotating rod 20 can be reversed. When the rotating rod 20 rotates, it can engage and drive the two sets of rack plates 17 to move towards the corresponding adjusting rods 13. When the rack plates 17 move, they can drive the T-shaped block 16 and the plug-in block 18 to move. When the T-shaped block 16 moves, it can slide with the fixed block 15.

[0028] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that when the two sets of plug-in blocks 18 are respectively plugged into the slots 14 inside the corresponding adjustment rods 13, the support plate 2 can be released. When the support plate 2 is released, the adjustment rods 13 can fall on the plug-in blocks 18. In this way, the height of the display panel 3 can be adjusted, so that the staff can adjust the height of the display panel 3 according to their own situation and actual conditions.

[0029] In summary, when the display rack with the extractable extension is used, the two groups of connecting plates 7 can be pulled away from each other, and when the connecting plates 7 move, the two groups of slide rods 6 can slide in the corresponding through grooves 5, and when the connecting plates 7 move, the threaded knobs 8 can be moved, and the writing area of the display board 3 can be expanded by the two groups of extension plates 9, so that the staff can write more content on the display board 3 and the extension plate 9, thereby facilitating the staff to count and correct the data, and improving the practicability of the display rack. When the two groups of plug-in blocks 18 are respectively plugged into the clamping grooves 14 in the corresponding adjusting rods 13, the supporting plate 2 can be loosened, and when the supporting plate 2 is loosened, the adjusting rod 13 can fall on the plug-in block 18. In this way, the height of the display board 3 can be adjusted, so that the staff can adjust the height of the display board 3 according to their own and actual conditions. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0030] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
