Description

When performing plug-in connection for assembly, the connection structure is usually single, and only rod-shaped objects can be connected to form a framework. The outer skin and internal partitions need to be reinstalled and connected separately. The three are not an interconnected whole, with poor mechanical structure, and it is difficult to perform convenient plug-in connection according to actual assembly requirements. In addition, a single plug-in connection cannot achieve the three-axis communication of multiple connecting pipe fittings, and after connecting with pipes and plates, it cannot achieve the three-axis communication of the overall structure. The stability of the assembled structure during reinforcement is not good. In addition, additional fastening components need to be added separately for reinforcing the assembled structure.
