Description

Technical Field

[0001] The utility model belongs to the field of exhibition halls, and in particular relates to a height adjustment device for exhibition hall booths. 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 CN213786526U discloses a height adjustment device for an exhibition hall booth, including: a chassis, a guide rail, a slider, a pull rod, a folding lifting rod, a lifting plate, a motor, a gear, a toothed rod and a cylinder; the guide rail is symmetrically installed on the upper end surface of the chassis, the slider is installed on the slide rail, the pull rod is welded on the slider symmetrically, the folding lifting rod is hinged on the slider symmetrically, the lifting plate is installed on the top of the folding lifting rod, the motor is symmetrically installed on the pull rod, the gear is installed on the output end of the motor, the toothed rod is transversely installed on the chassis and meshes with the gear, and the cylinder is installed on the outer side of the upper end of the chassis and the outer side of the lower end of the lifting plate. The exhibition hall booth height adjustment device provided by the utility model can adjust the booth height arbitrarily according to needs, and has a simple structure and low manufacturing cost.

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

[0005] According to the description in paragraph 0018 of the above-mentioned document, "The motor is controlled to rotate forward and reverse through the switch, so that the gear moves left and right on the gear rod, controls the folding lifting rod to rise or fall, and then controls the lifting and lowering of the lifting plate. The slider installed on the guide rail limits the folding lifting rod and reduces the sliding friction of the folding lifting rod. The meshing of the gear and the gear rod provides a good thrust for the folding lifting rod." There is no guide structure on one side of the gear. When the output end of the motor drives the gear to rotate, the gear is prone to tilt on the gear rod, which will cause the gear to detach from the gear rod.

[0006] Therefore, a device for adjusting the height of exhibition hall booths is proposed to solve the above-mentioned drawbacks. Utility Model Content
