Description

Pipe connector {Pipe connector}

The present invention relates to a technology for easily and conveniently connecting a plurality of pipes to each other as a pipe connector.

The pipe connector is a connecting member that allows a plurality of pipes to be easily connected to each other. Since a user can easily connect a plurality of pipes in a desired shape using a pipe connector, various structures using pipes as members can be easily manufactured. Such structures may include aerial work platforms, simple tables, shelves, and the like.

As a related prior art, there is Utility Model Publication No. 1991-0000059 (“shower support pipe connector). The above technique is characterized in that a pin insertable at the end of the pipe is formed in the body of the connector, and the pipe is connected to each other by inserting the pin into the pipe.

However, such a fitting structure is easy to fall out again, making it difficult to integrate the pipe structure. In addition, during long-term use or repeated assembly/disassembly, the bonding strength of the fitting structure is gradually weakened, and clearance of the bonding site occurs, thereby reducing the stability of the structure.

Accordingly, there is a need for a technique for stably supporting a load acting on a pipe structure through a pipe connection part, while increasing the coupling force and durability of the connection part.
