Description

Technical Field

[0001] This utility model relates to the field of agricultural economic statistics equipment technology, specifically to an agricultural economic statistics display board. Background Technology

[0002] Agricultural economic statistics can reflect the relevant situation of rural economic activities, which is helpful for the government to understand rural areas and provides great reference for the government to formulate relevant rural policies, laws and regulations. It also helps rural residents understand agricultural economic statistics and plan their own economic activities. Agricultural economic statistics can play a significant role at both the macro and micro levels.

[0003] Existing agricultural economic statistics display boards have a simple structure, cannot be folded, and cannot meet transportation needs. They are inconvenient for data presenters to carry when explaining rural economic conditions to rural residents, and cannot navigate narrow spaces, greatly limiting their effectiveness. Furthermore, the small display panels lack sufficient space to effectively showcase the data. Therefore, there is an urgent need to design a new agricultural economic statistics display board to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural economic statistics display board to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An agricultural economic statistics display board includes a support tube, an extension folding mechanism slidably connected to the outside of the support tube, the extension folding mechanism including an extension tube, a handle fixedly connected to the outer wall of one side of the extension tube, a fixed plate fixedly connected to the upper end of the other side of the extension tube, a lower fixed plate fixedly connected to the upper end of one side of the extension tube above the handle, a rotating shaft rotatably connected to the top of the inside of the extension tube, the rotating shaft being a T-shaped shaft, an upper fixed plate fixedly connected to the outside of the rotating shaft, a pair of rotatable fixed brackets fitted to the outside of the rotating shaft, a base fixedly connected to the lower surface of the support tube, a pair of supporting sliding mechanisms movably mounted on both sides of the base, and a folding panel provided above the extension folding mechanism.

[0007] Preferably, the folding panel includes a large panel respectively mounted on two fixed frames, a plurality of hinges are fixedly connected to the top outer wall of the pair of large panels, and a flip-up small panel is fixedly connected to the top of the pair of large panels via hinges.

[0008] Preferably, a U-shaped retaining plate is movably fitted onto one side of the contact surface between the large panel and the small panel.

[0009] Preferably, the top outer wall of the fixing frame has a through hole, and a U-shaped tube is movably inserted into the through hole.

[0010] Preferably, the base includes a base shaft, an upper base plate is fixedly sleeved on the upper outer end of the base shaft, a lower base plate is fixedly sleeved on the lower outer end of the base shaft, and a support shaft is fixedly connected between the lower surface of the upper base plate and the upper surface of the lower base plate.

[0011] Preferably, the support sliding mechanism includes a support arm rotatably sleeved outside the support shaft, and a caster wheel is fixedly connected to the lower surface of the support arm at the end away from the support shaft.

[0012] In the above technical solution, the agricultural economic statistics display board provided by this utility model has the following beneficial effects:

[0013] (1) This utility model can fold the data display board by extending the folding mechanism and folding panel to reduce the volume and avoid occupying storage and transportation space. When data presenters have the task of giving presentations outside, they can fold the data display board and easily put it into the trunk of the vehicle for convenient transportation.

[0014] (2) After the data display board is folded by the extension folding mechanism and the folding panel, the display board can be lifted by the handle on the extension tube. It can be easily passed through narrow and low doors or elevators, making it convenient for data presenters to carry with them, enter and exit the conference room, and move the presentation location.

[0015] (3) The four foldable panels can be unfolded when in use, which is convenient to carry and also ensures that the data presenter has enough space to use, avoiding the inability to display the full data due to the small display panel, and ensuring the normal presentation of the data presenter.

[0028] Specifically, in this embodiment, a support tube 1 is included, and an extension folding mechanism 2 is slidably connected to the outside of the support tube 1. The extension folding mechanism 2 includes an extension tube 21. Several bolt holes are opened on both sides of the support tube 1 and the extension tube 2. The height of the display panel is adjusted by fixing the bolts to different hole positions. A handle 22 is fixedly connected to the outer wall of one side of the extension tube 21. A fixing plate 23 is fixedly connected to the upper end of the other side of the extension tube 21. A lower fixing plate 26 is fixedly connected to the upper end of one side of the extension tube 21 above the handle 22. A rotating shaft 24 is rotatably connected to the top end inside the extension tube 21. The rotating shaft 24 is a T-shaped shaft. An upper fixing plate 27 is fixedly sleeved on the outside of the rotating shaft 24. When the display panel is unfolded and erected, the rotating shaft 24 is fixed by passing a pin through the holes on the upper fixing plate 26 and the lower fixing plate 27. A pair of rotatable fixing brackets 25 are sleeved on the outside of the rotating shaft 24. Several holes are opened on one side of the fixing brackets. The large panel is fixed to the fixing brackets 25 by screws. A base 4 is fixedly connected to the lower surface of the support tube 1.

The U-shaped tube 6 is formed by bending a steel pipe in one piece. The display panel is kept still by restricting the movement of the fixing frame 25.

[0032] In one embodiment of this utility model, the base 4 includes a base shaft 41, an upper base plate 42 is fixedly sleeved on the upper outer end of the base shaft 41, through holes are opened at both ends of the upper base plate 41, a lower base plate 43 is fixedly sleeved on the lower outer end of the base shaft 41, a support shaft 44 is fixedly connected between the lower surface of the upper base plate 42 and the upper surface of the lower base plate 43, and the upper base plate 41 and the lower base plate 43 are formed by sheet metal laser cutting.

[0033] In another embodiment of the present invention, the support sliding mechanism 5 includes a support arm 51 rotatably sleeved on the outside of the support shaft 44. The support arm 51 has a through hole on the side near the support shaft 44. When placing the display panel, the bolt is fixed by passing through the through hole of the support arm 51 through the through hole at both ends of the base plate 41. A caster wheel 52 is fixedly connected to the lower surface of the support arm 51 away from the support shaft 44.

[0034] Working principle: When folding the agricultural economic statistics display board, first remove the U-shaped card plate 34 by removing the pin on the U-shaped card plate 34, then fold the small panel 32 backward by 180°, then remove the U-shaped tube 6, and at the same time fold the two large panels inward by 90°, then fold the rotating shaft 24 downward by 180°, and finally pass the pin through the hole on the fixing plate 27 and the hole on the two fixing brackets 25 into the hole in the fixing plate 26 to fix the top flipping part, remove the bolt on the extension tube 21 so that the extension tube 21 and the support tube 1 slide relative to each other to reduce the height of the data display board, then put the bolt through the adjustment hole of the extension tube 21 and the support tube 1 and tighten it, remove the four pins on the base plate 2 so that the support arm 51 can rotate, and when the handle 22 is held, the support arm 51 hangs down naturally, and only needs to be tied with a rope. To unfold the display board, simply reverse the above steps.
