Description

A wire pipe connection structure

technical field

The utility model relates to the technical field of electric pipeline connection, in particular to a line pipe connection structure.

Background technique

The connection between the threading pipe and various junction boxes, and the connection between the pipe and the joint is widely used in the installation and construction of building water and electricity. The traditional electrical pipeline connection generally adopts threaded type, that is, the online pipe is provided with external threads, and the matching joints are provided with internal threads, and the two are connected to each other through internal and external threads; or fixed by screw tightening and compression, that is, there are screws on the joints The hole has one or two screws with special structure. When installing, insert the tube into the joint, screw in the screw clockwise with a screwdriver until the tube is tightened and fixed by the screw, and then tighten it firmly to break the screw cap and the screw rod, complete Install.

The former is the most cumbersome to use, but it must be adapted to different lengths of pipes with threads at both ends to be connected in different occasions, or the pipes need to be cut to make threads and then connected to the joints. The process is cumbersome and complicated.

Although the latter simplifies the construction process and can be assembled with a screwdriver, it has not been fundamentally simplified, and its assembly efficiency needs to be further improved, and its production cost needs to be further reduced.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a line pipe connection structure, which solves the problems in the prior art that the structure is not simple enough, the assembly efficiency is low, and the cost is high.

The technical scheme adopted by the utility model to solve the technical problem is: a wire pipe connection structure, including a wire pipe and a sleeve, the wire pipe is inserted into the sleeve, and the sleeve is provided with a wedge-shaped structure protruding inward , the protrusion height of the wedge-shaped structure gradually increases along the insertion direction of the corresponding wire tube, and the wire tube is tightly connected with the casing under the extrusion action of the corresponding wedge-shaped structure.

Preferably, the wedge-shaped structure is formed by stamping.

Preferably, a plurality of wedge-shaped structures are evenly arranged along the circumferential direction of the casing.

Preferably, the casing is a straight pipe or a curved pipe, and the wedge-shaped structures are provided near both ends of the casing.

Preferably, the casing is a metal pipe.

Preferably, the line pipe is a metal pipe.

Positive effects of the utility model: the utility model changes the structure of the existing wire pipe joint, cancels the screw holes and screws, and replaces it with a wedge-shaped structure to realize the mutual fastening connection of the wire pipe and the joint. The casing with wedge-shaped structure of the utility model reduces the processing steps during production, saves parts such as screws, reduces the cost, and has a simpler structure, which saves packaging costs; The wire tube can be inserted into the casing to a certain depth to realize the fast connection between the two, and the assembly operation is simpler. This faster and simpler connection method greatly improves the connection efficiency.
