Description

Detachable pipe plug

Technical Field

The invention relates to a hardware pipe fitting, in particular to a detachable pipe plug connector.

Background

The pipe joint is a connecting tool between a pipeline and a connecting point between an element and the pipeline, and can be disassembled and assembled. Plays an indispensable important role in the pipe fitting, which is one of the two main components of the hydraulic pipe. The pipe joint is used for straight line connection of instruments and the like, and the connection form is socket welding or threaded connection. The device is mainly used for low-pressure pipelines with small calibers, parts needing to be frequently assembled and disassembled or final adjustment of pipelines using threaded pipes. The structure form is preferably a metal surface contact sealing structure, and the gasket sealing structure form is usually used for general pipelines for conveying water, oil, air and the like and is made of malleable cast iron materials. In addition, the use requirement, the price and the like are also factors to be considered when selecting. Pipe joints are of various types, and common pipe joints can be generally divided into hard pipe joints and hose joints. If the connection mode of the pipe joint and the pipeline is divided, the hard pipe joint has three types of flaring type, clamping sleeve type and welding type, and the hose joint is mainly a fastening type hose joint.

Present joint is usually direct to be connected with the pipeline, after both take place the relation of connection, connection between the two is irreversible, if need separate both, need change new joint after cutting the pipeline, or need pull out to use again after cutting the pipeline after the joint by force, and the pipeline is in case the cutting condition takes place, so the pipeline length of given setting can change, can cause the error to carrying out the connection of pipeline and joint once more, thereby influence the connection leakproofness between the two.

Therefore, a new solution is needed to solve this problem.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a detachable pipe plug connector, wherein a pipeline is sleeved on an outer limiting block of a plug pipe part and then a clamping assembly is pushed to the outer limiting block to clamp the pipeline, and when the pipeline is separated, the clamping assembly is enabled to be reversely displaced so that the outer wall of the pipeline is not clamped any more.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a removable pipe bayonet joint, includes hexagonal portion and sets up the intubate portion at its both ends, one side intubate portion sets up the through-hole that runs through to another side intubate portion, a plurality of outer stoppers of the one end fixedly connected with of hexagonal portion are kept away from to intubate portion, and is a plurality of the outside sliding connection of outer stopper has can dismantle the clamping component who is connected with intubate portion.

Through adopting above-mentioned technical scheme, when people need attach fitting and pipeline, people can insert the pipeline on the intubate portion, then through clamping assembly on the intubate portion displacement to make clamping assembly clip the pipeline, and then make when people need to dismantle joint and pipeline, people only need make clamping assembly and pipeline break away from, thereby make the pipeline no longer by the clamping assembly centre gripping on the intubate portion, can make the pipeline and connect the emergence to break away from.
