Abstract

The utility model relates to a coupling part for oxygen or gas pipes, especially a coupling joint for oxygen pipes. The utility model provides a coupling part for oxygen pipes, comprising joint body with conical surface and inverted conical surface, clasp with inner conical surface and lock nut. The joint body inserts into the pipe hole; the clasp is arranged outside the pipe; the clasp and pipe are locked with the joint body through lock nut so as to implement the connection between oxygen or gas pipes and pipeline attachment and the connection between pipes as well as quick change of joint and pipe.

Description

Oxycoal gas pipe jointing

Technical field

The utility model relates to the connected element of a kind of oxygen, gas pipe, relates in particular to a kind of oxycoal gas pipe jointing.

Background technique

Connection between being connected of oxygen hose, gas pipe and pipeline fittings, the tube and tube has at present and adopts the joint that has several zigzag fashion ring-types to insert in the pore, uses the anchor ear banding then.Because joint has zigzag ring,, cause the inconvenience when changing joint or pipe so after joint inserts pore, be difficult for extracting once more.

Summary of the invention

The purpose of this utility model is to provide a kind of oxycoal gas pipe jointing, realize oxygen hose, gas pipe and pipeline fittings be connected and tube and tube between connection.

The purpose of this utility model is achieved in that a kind of oxycoal gas pipe jointing, is made up of fittings body, snap ring, locking nut, and fittings body inserts in the pore, is placed in outside the pipe with snap ring, uses locking nut shackle and pipe in fittings body;

Described fittings body is provided with a conical surface and inverted cone face and at nose-circle degree of slipping over, other is provided with a locking screw thread;

Described snap ring, its end are provided with an inner conical face adaptive with the fittings body conical surface;

Described locking nut, on it on internal thread and the fittings body screw thread match, and promote snap ring pressing pipe on fittings body.

Oxycoal gas pipe jointing of the present utility model is used in the connection between being connected of oxygen hose, gas pipe and pipeline fittings and the tube and tube, can realize the quick replacing of joint and pipe.
