Description

Technical Field

[0001] The utility model mainly relates to the technical field of temporary stands, in particular to a high and stable temporary detachable stand. Background Art

[0002] Grandstands generally refer to seats provided for spectators to watch large-scale collective activities such as cultural and sports events, entertainment performances, etc. They mainly refer to the audience seats surrounding the performance or competition venues. Temporary stands, as the name suggests, are viewing stands temporarily built in random venues for spectators to use, so that the audience can see what is happening on the stage more clearly and in a more three-dimensional way.

[0003] After searching, a stable and high temporary detachable metal stand disclosed in the publication number CN216380760U is designed to solve the technical problem that the metal stands in the prior art are not convenient to be disassembled when they need to be moved and stored, and lack a certain stable support structure when they are used. The metal stand includes a supporting frame, a stable support module installed on the supporting frame, and an adjustment clamping module connected to the stable support module for adjustment and clamping; a detachable stand seat assembly is arranged on the upper side of the adjustment clamping module, a connecting assembly for assembly and connection is arranged on the outer side of the supporting frame, and a vertical heightening support column is arranged on the outer side of the stable support module. The metal stand can have good stability when in use through the stable support module and the reinforced feet, and the stand seat assembly can be adjusted and clamped by adjusting the cylinder, so that it is easy to disassemble and assemble.

[0004] However, the above scheme still has some shortcomings when used. The position of the stand seat assembly set in the above scheme cannot be adjusted, which is not friendly to some spectators with taller heights, causing spectators sitting in the back seats to easily have conflicts with customers in the front row when using it, bringing inconvenience to the spectators and reducing the practicality of the stand. At the same time, in the above scheme, the two separate stands are connected by a third fixing member. This connection method is easy to be pulled out by some naughty children when in use, resulting in certain safety hazards and poor stability.

[0005] Therefore, we provide a stable and high temporary detachable stand to solve the defects of the above solutions. Utility Model Content
