Abstract

The utility model relates to a quick pipe joint for general mechanical engineering, comprising an intubation pipe 1, a pin 2, a self locking handle 3, a sealing ring 4 and plug seat 5. The quick pipe joint is characterized in that the intubation pipe 1 is inserted into the plug seat 2; the upper end of the plug seat is fixed with the pin 2 which is movably connected with the self locking handle with two eccentric cam-shaped heads; the two eccetric cam-shaped heads are tightly press fit with or disengaged from two concave half arc faces on the left and right sides of an outside circle at the medium-end of the plug seat 1. Therefore, the quick pipe joint can quickly conduct and shut up liquid in a pipe. Because the pressfitting point of the quick pipe joint adopts one face joint, the quick pipe joint has the advantages of long service life, high reliability, simple structure and easy operation.

Description

Quick pipe joint

The utility model is used for family expenses chemical industry, daily-use chemical industry and food oil lipid industry, the rapid pipe joint of common mechanical engineering.

Existing joint adopts the cam mechanism of the spring pressing of some contact, and the point that coincide is easy to wear, uses not for a long time, just causes pressing tightly not cause pipeline liquid to leak outside.

The purpose of this utility model is in order to overcome above-mentioned disadvantage, protruding ball type handle of a kind of off-centre and the tight pressing of intubate to be provided, reach good seal performance, the rapid pipe joint that the life-span is long.

The utility model is achieved in that

The utility model is made up of intubate, pin, eccentric handle, seal ring and socket, and intubate has interior cavity, and there is an internal thread its upper end, is connected with an end of fluid pipeline, and each side there is a spill semicircle cambered surface at middle-end cylindrical place; Spill semicircle cambered surface is contained in the socket upper end, and the socket corresponding with it each side has a pin, and a cavity is arranged in the socket, and the cavity lower end is an internal thread, is connected with the fluid pipeline the other end; The ring packing figure of through hole is arranged in the cavity intermediate portion is installed one, combine closely with the intubate lower end surface above the sealed picture, prevent liquid leakage; Activity is equipped with a self-locking handle on every pin, its head is eccentric protruding sphere-like and handle is connected as a single entity, protruding spheroid is eccentric installs the pin of Rotate 180 ° relatively only, when handle is rotated down from top to bottom gradually, spill semicircle cambered surface B point, A point all are that the tight pressing of intubate and socket is the binding site of one, cross pin center and link to each other with A, B respectively, and its angle is the tight linkage section of cannula hub for 20 °～30 °, other position sections are that intubate and socket are thrown off section, and intubate can be extracted out.

The utility model advantage is that joint structure is simple, can connect fast or separate, and intubate and socket have an area segments pressing, overcome the shortcoming that the some pressing is easy to wear and spring lost efficacy easily, improved the working life of joint like this, good seal performance reaches practical, reliable purpose.

The utility model will be further described below in conjunction with drawings and Examples.

Be numbered in the accompanying drawing:

4-sealed picture 5-socket 10-internal thread

The eccentric protruding spheroid 31-handle of 11-spill semicircle sphere 30-

The 50-internal thread

Embodiment 1, and the utility model is made up of intubate 1, pin 2, self-locking handle 3, sealed picture 4 and socket 5, and logical up and down inner chamber is arranged in the intubate 1, and there is internal thread 10 the inner chamber upper end, and each side there is a spill semicircle sphere 11 at the cylindrical place of intubate 1 Lower Half; Logical up and down inner chamber is arranged in the socket 5, there is internal thread the cavity lower end, the O-ring seal 4 of through hole is arranged in installing one in the middle of the cavity, combine closely with intubate 1 lower end surface above the seal ring 4, spill semicircle sphere 11 is contained in socket 5 upper ends, and socket 5 both sides of corresponding left and right sides spill semicircle sphere fix a pin 2 respectively, and pin 2 passes eccentric protruding spheroid 30, and both flexibly connect; A, the B point and pin 2 lines of centres on the eccentric protruding spheroid 30, its angle is that intubate 1 closely is connected the pressing zone with socket 5 for 20 °～30 °.

Embodiment 2, and the utility model in addition part modular construction and interconnected relationship thereof is substantially the same manner as Example 1, its in addition part all adopt stainless steel material, the HRC of eccentric protruding spheroid 30 is 40～50.
