Stair capable of being dismounted and mounted and used for booth

Abstract

The invention relates to a stair capable of being dismounted and mounted and used for a booth. The stair comprises two horizontally-opposite telescopic side frames, and each side frame is composed of an upper frame body and a lower frame body; a plurality of transverse inserting holes are formed in the upper frame body, and upper sleeves are mounted in all the inserting holes correspondingly; a plurality of transverse inserting holes are formed in the lower frame body, and lower sleeves are mounted in all the inserting holes correspondingly; the stair further comprises a plurality of stair plates, each stair plate comprises a plate body, pin shafts are fixedly mounted at the two ends of each plate body correspondingly, and every two corresponding pin shafts are located in one set of transversely-corresponding sleeves correspondingly; the stair further comprises a top fixing plate and a bottom fixing plate, top anchorage plates are arranged at the bottoms of the two ends of the top fixing plate correspondingly, the upper ends of the two upper frame bodies are connected with the two top anchorage plates in a hinged mode, bottom anchorage plates are arranged at the tops of the two ends of the bottom fixing plate correspondingly, and the lower ends of the two lower frame bodies are connected with the two bottom anchorage plates in a hinged mode; and the stair further comprises an adapting piece for bridging of the top fixing plate and a second-floor floor slab, and the bottom fixing plate is fixed to the ground through 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...

AI Technical Summary

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
