Description

Technical Field

[0001] The utility model belongs to the field of exhibition stands, and in particular relates to an exhibition stand device which is convenient for lifting. Background Art

[0002] A booth is a storage table used for exhibitions, which is a shelf used to display products at various exhibitions. The booth can display the characteristics of the products more comprehensively, making it easier for exhibitors to observe the products and improving the display effect of the products.

[0003] The patent application with publication number CN218246606U discloses a height-adjustable exhibition stand, comprising: an exhibition board, a fixed cylinder is fixedly connected to the upper side of the exhibition board, an axial hole is provided on the upper side of the fixed cylinder, a lifting rod is rotatably connected to the hole wall of the axial hole through a bearing, a sleeve is provided on the movable sleeve outside the lifting rod, a fixed plate is fixedly connected to the upper end of the sleeve, a plurality of pin holes are provided on the fixed plate, a same tension spring is fixedly connected between the upper end of the lifting rod and the lower side of the fixed plate, two sliders are symmetrically fixedly connected to the rod wall of the lifting rod, two sliding holes are symmetrically provided on the vertical side wall of the sleeve, the slider passes through the sleeve through the sliding hole, a threaded hole is provided on the cylinder wall near the lower end of the sleeve, and a locking screw is threadedly sleeved in the threaded hole. The utility model can quickly pull the exhibition board downward, which is convenient for lowering the height of the exhibits for observation, and effectively improves the convenience of adjusting the height of the exhibition stand.

[0004] However, the above technology has the following disadvantages when used:

[0005] According to the description in paragraph 0020 of the above-mentioned document, "the upper end of the lifting rod is fixedly connected to the lower side of the fixed plate with a same tension spring, the rod wall of the lifting rod is symmetrically fixedly connected with two sliders, the vertical side wall of the sleeve is symmetrically provided with two sliding holes, the sliders penetrate the sleeve through the sliding holes, the sleeve wall near the lower end is provided with a threaded hole, and a locking screw is threadedly sleeved in the threaded hole". It can be seen that the locking screw is positioned on the outer wall of one side of the lifting rod through the threaded hole, while the outer wall of the other side of the lifting rod is not provided with a positioning structure. If the exhibits placed on the upper side of the fixed plate are heavy, the inner wall of the sleeve is easy to slide on the outer wall of the lifting rod, reducing the flexibility of the booth when in use.

[0006] Therefore, a booth device that is easy to lift is proposed to solve the above drawbacks. Utility Model Content
