Abstract

The invention discloses a three-dimensional gear transverse / vertical inside-tightening direct-type casing pipe connection structure. The connection structure comprises a pipe body and a clamp. The clamp comprises a clamp strap and a fixing device for fixing the clamp strap. The fixing device comprises a worm and a housing, the clamp strap is arranged on the inner side of the pipe body, an open hole is formed in the position, in contact with the clamp strap, of the pipe body, the housing penetrates through the open hole in the pipe body to be fixed at one end of the clamp strap, the other end of the clamp strap penetrates into the pipe body or is exposed outside the pipe body by penetrating through the housing, the worm is arranged inside the housing and matched with the outer edge of the housing in a rotating mode, and a tooth groove of the clamp strap is meshed with external threads of the worm. Original point contact is changed to surface contact in the connection structure, the stress area is large, loosening does not easily occur, stability is good, fixing capacity is high, impact of external force can be resisted, concrete is prevented from entering the connection structure, construction can be carried out in the transverse and longitudinal directions, good practicability is achieved, the structure is simple, work efficiency is improved, and work cost is reduced.

Description

technical field

[0001] The invention relates to a connection structure, in particular to a three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure. Background technique

[0002] The three-dimensional gear horizontal / vertical inner tight direct threading pipe connection structure is a component used to connect two threading pipes together.

[0003] The threading pipe is the pipe used for the power supply line to pass through. During the construction of the building, the threading pipe is arranged in the wall, roof or building in advance, which is convenient for the later electrician wiring and construction, and also facilitates the later circuit maintenance. Moreover, the wires are arranged inside the wall, which is not only beautiful, but also improves safety. In the process of arranging the threading pipes, two threading pipes need to be connected together with a three-dimensional gear horizontal / vertical inner tight direct threadi...
