Stair capable of being dismounted and mounted and used for booth

Abstract

The invention relates to a detachable staircase for a booth. It includes two horizontally opposite retractable side frames, each side frame is composed of an upper frame and a lower frame; a plurality of horizontal jacks are arranged on the upper frame, and upper sleeves are installed in each jack. The lower frame is provided with a plurality of horizontal jacks, and lower sleeves are installed in each jack; it also includes a plurality of stair boards, the stair boards include a board body, and pin shafts are installed and fixed at both ends of the board body. The two pin shafts are located in a group of horizontally corresponding sleeves; it also includes a top fixing plate and a bottom fixing plate, top lugs are arranged at the bottom of both ends of the top fixing plate, and the upper ends of the two upper frames are connected with the two top lugs respectively. The plate is hingedly connected, and the top of both ends of the bottom fixed plate is provided with bottom lugs, and the lower ends of the two lower frames are respectively hingedly connected with the two bottom lugs; also includes an adapter for bridging the top fixed plate with the second floor The bottom fixing plate is fixed to the ground with ground anchors.

Description

technical field [0001] The invention belongs to the technical field of display and exhibition, in particular to a detachable staircase for a booth. Background technique [0002] In the field of display and exhibition, when it comes to the construction of on-site display platforms and display spaces, stair devices are generally used to build passages between the ground and the display platforms above. Since the time for displaying the exhibition will not be too long, the display racks, booths, stairs and other devices are usually disassembled after the exhibition, and then stored or transported to the next exhibition site for assembly after complete disassembly. Therefore, the staircase device needs to have the characteristics of quick disassembly and assembly, and easy transfer and transportation. [0003] Existing stairs for booths generally have a complex structure, and the steps of on-site construction and disassembly are cumbersome. The structure generally includes sid...

Problems solved by technology

[0003] Existing stairs for booths are generally complex in structure, and the steps of on-site construction and disassembly are cumbersome

The structure generally includes side frames on both sides, and multi-level ladders are fixedly installed between the two side frames. Side rails are also installed above the side frames as handrails and protective mechanisms. During construction, each part of the stairs needs to be fixed and installed one by one. , and use bolts to fix the parts, disassembly and assembly is very time-consuming and laborious

In addition, the existing stair installations are generally of fixed structure, that is, the size and location of the installation have been determined. Inconsistency with the overall height of the stairs, etc., the adjustment of the structure on the spot is not only very cumbersome and laborious, but also easily delays the time of booth construction, and at the same time causes the display effect to deteriorate
