Problems solved by technology

Although this kind of traditional quick connector can be quickly inserted, it cannot be quickly disassembled. During the process of clamping the pipe fittings by the claws, it is easy to cause damage to the pipe fittings. In the long run, the parts connected by the claws will cause rust. In the end, the sealing performance is not good and it cannot be disassembled, so that the joint cannot be used repeatedly and quickly, and it is easy for the operator to accidentally injure during the disassembly process, which poses a certain hidden danger to the personal safety of the operator.

Embodiment Construction

[0018] refer to figure 1 , is a pipeline quick joint disclosed in the present invention. At least one port of the pipe body 10 expands outwards to form a first neck expansion cavity 11, and the first neck expansion cavity 11 expands outwards to form a second neck expansion cavity 12. The ports of the two neck expansion chambers 12 contract inwardly to form a constriction part 13, and the first neck expansion chamber 11 and the second neck expansion chamber 12 are connected by a transition section 14, and the transition section 14 moves from the inside to the outside in the direction of the neck expansion chamber 13 tilt. A sealing ring 15 is arranged inside the first neck expansion cavity 10 , the outer diameter of the sealing ring 15 is equal to the inner diameter of the first neck expansion cavity 10 , and the inner diameter is smaller than the inner diameter of the pipe body 10 . This can effectively enhance the sealing performance of the pipe fittings when they are plugge...

Abstract

The invention relates to the technical field of valve accessories, in particular to a quick pipeline joint. The quick pipeline joint is characterized in that a pipe body of the quick pipeline joint is provided with a first neck expanding cavity and a second neck expanding cavity, and a port of the second neck expanding cavity shrinks inwards to form a necking part I; a sealing ring is arranged in the first neck expanding cavity, a lock sleeve is arranged in the second neck expanding cavity, a port, corresponding to the necking part I, of the lock sleeve shrinks inwards to form a necking part II, a convex ring is arranged at the necking part II and extends out of the necking part I, a wave spring, a steel ball retainer and a withdrawal sleeve limited by the necking part II are sequentially arranged in the lock sleeve in the direction towards the necking part II, a plurality of through holes are circumferentially and uniformly distributed in the side wall of the steel ball retainer, a small steel ball capable of moving for a certain distance in the axial direction is arranged in each through hole, and two corresponding spherical surfaces of the steel ball extend out of two ports of the through hole respectively. The quick pipeline joint has the advantages as follows: the service life of a product can be effectively guaranteed, quick insertion and dismounting of the product in the long-term use process can be realized conveniently, accordingly, the working efficiency is improved, and unnecessary potential safety hazard is avoided.

Description

technical field [0001] The invention relates to the technical field of valve body fittings, in particular to a pipeline quick connector. Background technique [0002] A quick connector is a connector that can realize quick connection or disconnection of pipelines. At present, the traditional quick connector includes a shell with more than two inner cavities connected to the interface. At least one of the interfaces is provided with a quick connector. A lock cap is screwed on the cavity, and the port of the lock cap is provided with a constriction. The inner cavity of the neck expansion cavity is provided with an elastic compression ring, and the compression ring is provided with claws along its circumference. There is a circular unlocking ring, and the unlocking ring reveals the necking. Although this kind of traditional quick connector can be quickly inserted, it cannot be quickly disassembled. During the process of clamping the pipe fittings by the claws, it is easy to c...
