Abstract

This utility model provides a quick-change adapter, including a body. A positioning ring is installed at one end of the body, and a sealing ring is installed between the body and the positioning ring. A locking ring is installed on the positioning ring, and a tube-removing sleeve is engaged with the locking ring. A compression sleeve is fitted over the tube-removing sleeve. A threaded connector is connected to the other end of the body. A sealing ring is present at the connection between the threaded connector and the body, and another sealing ring is present at the other end. This quick-change adapter has a simple structure, is easy to install, and offers high continuous stability, significantly reducing production and installation costs and improving work efficiency.

Description

A quick change connector

technical field

The utility model relates to a quick conversion joint.

Background technique

Pipe joints are detachable connection points between pipes and components, and are very important parts of pipe fittings. However, the currently used joints have problems such as inconvenient installation, poor sealing, and low connection stability.

Utility model content

The purpose of the utility model is to solve the above-mentioned problems in the prior art, and provide a quick conversion joint, which has a simple structure, convenient installation, high connection stability, effectively reduces production costs, improves efficiency, and enhances practicability.

In order to achieve the above object, the technical solution of the utility model is:

A quick conversion joint, including a body, a positioning ring is installed at one end of the body, a sealing ring is installed between the body and the positioning ring, a locking ring is installed on the positioning ring, and the locking ring is clamped There is a retracting sleeve, and the outer casing of the retracting pipe is connected with a compression sleeve, the other end of the body is connected with a threaded joint, the joint between the threaded joint and the body is provided with a sealing ring, and the other end is provided with a sealing ring.

The locking ring is a hollow cylinder, with a larger opening at the end connected to the retracting sleeve, uniform opening grooves, and a narrower opening at the end connected with the locating ring, and snaps into the annular groove in the locating ring through its own material elasticity.

There is a step on the pipe withdrawal sleeve, and a cylindrical sleeve is welded on the step. There is an annular groove on the pipe withdrawal sleeve. The cylindrical sleeve of the pipe withdrawal sleeve matches the inner tapered surface of the compression sleeve, and the pipe withdrawal The sleeve and the locking ring snap into the positioning ring and are loaded into the body together.

The beneficial effects of the utility model are: a quick conversion joint with simple structure, convenient installation and high continuous stability

Detailed ways

Example 1

As shown in Figure 1, a quick conversion joint includes a body 4, a positioning ring 6 is installed at one end of the body 4, a first sealing ring 5 is installed between the body 4 and the positioning ring, and a positioning ring is installed on the positioning ring. A locking ring 7, on which a retracting sleeve 8 is clamped, and a compression sleeve 9 is connected on the outer sleeve of the retracting sleeve 8, and the other end of the body 4 is connected with a threaded joint 1, and the threaded joint There is a second sealing ring 3 at the connection between 1 and the body 4, and a third sealing ring 2 at the other end.

The locking ring 7 is a hollow cylinder, and the opening at the end connected to the retracting sleeve 8 is relatively large, and an opening groove 10 is evenly opened, and the opening at the end connecting with the positioning ring is narrowed, and is snapped into the annular groove in the positioning ring 6 through its own material elasticity. .

A step 11 is provided on the retracting sleeve 8, a cylindrical sleeve 12 is welded on the step 11, an annular groove 13 is arranged on the retracting sleeve 8, the cylindrical sleeve 12 of the retracting sleeve 8 and the compression sleeve 9 Cooperate with the inner tapered surface of the inner cone, snap the retracting sleeve 8 and the locking ring 7 into the positioning ring 6 and put them into the body 4 together.

The quick changeover joint of this embodiment has simple structure, convenient installation, high continuous stability, effectively reduces production cost, and enhances practicability.
