Description

Connection module of combined frame

The present invention is related to the connection combination element of the frame rod body.

The rods and tubes of the frame can be assembled with joints to simplify the assembly method. The typical joint structure is to form a connection tube on different sides of a base for socket assembly of the rods and tubes of the frame. Based on the combined space type of the frame, the base needs to be formed on one side, two sides, three sides, or four sides in different permutations and combinations. There will be more than ten types of joint specifications prefabricated by the industry, and the cost of molds will be greatly increased. Storage is troublesome, and if a certain type of joint is missing, the frame cannot be assembled.

In addition, the typical joint structure has the same load capacity of each connection, and it cannot be changed according to the combined space type and load demand of the frame.

In view of the above problems, the present invention proposes a connection module applied to frame assembly.

Technical features of the invention:

A connection module of a combined frame, comprising: a main body module, which is a polyhedron, at least two faces of the main body module are respectively provided with a hollow body light-load joint; or at least two faces of the main module are respectively provided with a A heavy-duty connector that is a solid body; or, at least one surface of the main module is provided with a light-load connector that is a hollow body, and at least one surface of the main module is provided with a heavy-duty connector that is a solid body.

The purpose of the present invention:

According to the combined space type and static load requirements of the frame, choose a connection module with light load joints, heavy load joints alone, or a combination of light and heavy load joints to stably connect the frame rods in all directions of the frame, and Repeatedly quickly and without damage to disassemble the frame.
