Connector and pipe taking device

Abstract

The invention relates to the field of pipe connection and disassembly, and discloses a connector and a pipe taking device. The connector comprises an inner pipe, an outer pipe, a first elastic claw ring and an elastic tightening ring; an annular insertion groove for inserting a pipe is defined between the inner pipe and the outer pipe; the first elastic claw ring is provided with a first inverted tooth piece; the elastic tightening ring is provided with an inverted tooth part; and a first clamping point and a second clamping point are defined by the inner pipe and the outer pipe respectively. The beneficial effects are that the first inverted tooth piece and the inverted tooth part extend inwards and gradually incline backwards from outside to inside, and smooth inserting connection is guaranteed when a pipe is inserted; when the pipe is subjected to outward disengaging force, the first inverted tooth piece and the inverted tooth part can clamp the pipe and prevent the pipe from disengaging from the annular insertion groove, so that the pipe is prevented from falling off from the annular insertion groove; and meanwhile, the pipe can be easily taken out through the pipe taking device, mounting and dismounting are convenient, and the fixing effect is good.

Description

technical field [0001] The invention relates to the field of pipe connection and disassembly, in particular to a connection joint and a pipe taking device. Background technique [0002] At present, a large number of pipes are used in the fields of water supply and drainage, gas, etc. These pipes need to be connected by joints. The existing pipe joints usually adopt clamping type, flared sliding type and nut ferrule type, etc. However, there are certain disadvantages in the above-mentioned connection methods: 1. The clamp type joint and the flared sliding joint need professional plumbers to use special tools for installation, which is highly professional and cumbersome and complicated to operate. The joint leaks, and since the joint cannot be disassembled and reused after installation, if the joint leaks, the pipe can only be cut short, which makes the length of the pipe shorter, and new pipes and joints need to be re-laid, which is time-consuming, laborious and expensive. ;...

[0002] At present, a large number of pipes are used in the fields of water supply and drainage, gas, etc. These pipes need to be connected by joints. The existing pipe joints usually adopt clamping type, flared sliding type and nut ferrule type, etc. However, there are certain disadvantages in the above-mentioned connection methods: 1. The clamp type joint and the flared sliding joint need professional plumbers to use special tools for installation, which is highly professional and cumbersome and complicated to operate. The joint leaks, and since the joint cannot be disassembled and reused after installation, if the joint leaks, the pipe can only be cut short, which makes the length of the pipe shorter, and new pipes and joints need to be re-laid, which is time-consuming, laborious and expensive. ;2. The nut ferrule type joint needs to be installed with a wrench to tighten the nut, so there is a requirement for the installation space, and a wrench position needs to be reserved. There are certain installation limitations, and the nut is easy to loose after a period of use, which will cause leakage at the connection leak
