Description

Quick coupling

Technical Field

The utility model relates to a quick assembly disassembly's connecting device, especially quick-operation joint.

Background

The quick joint comprises a hydraulic quick joint and various fluid quick joints, and is a connecting device for quickly connecting or disconnecting pipelines and realizing quick assembly and disassembly. The quick connector has a bidirectional non-return function, so that the pipeline is free from leakage when disconnected, and therefore, the quick connector is widely applied to the fields of petroleum, metallurgy, hydropower, engineering machinery, ships, electromechanical equipment and the like. The quick joint connecting structure is the most important part of the quick joint, and the connecting mode and the structure of the quick joint directly determine the use convenience, the reliability and the product quality of the quick joint. The quick connector comprises a female connector and a male connector, wherein valve core structures are arranged in the female connector and the male connector, a flow passage is limited, and the flow passage is usually small.

Disclosure of Invention

In order to solve the technical problem that the above-mentioned runner receives the restriction because of case structure, the utility model provides a quick-operation joint.

The technical scheme of the utility model as follows:

quick-operation joint, including male joint and female joint, the male joint includes the plug, plug integrated into one piece, and the plug rear portion is outside protrusion, and the slope of plug rear portion inner wall, the anterior inner wall of plug is parallel with the central line, and the anterior outer wall front end of plug is sunken, and the depressed part is equipped with the inclined plane, and plug middle part outer wall is equipped with the stopping groove, and the female joint includes the casing, and casing rear portion inner wall slope sets up, and the casing front portion is equipped with the steel ball, and the steel ball is connected with the overcoat, and the overcoat cover is established at the casing.

An outer sleeve retainer ring is arranged in front of the outer sleeve.

And a shell O-shaped ring contacted with the recessed part at the front part of the plug is arranged on the inner wall of the shell.

Use the technical scheme of the utility model, novel structure, design benefit is simple and easy, and no valve core structure is fit for large-traffic, and processing is simple and easy, connects convenient and fast, intensity is high, resistant owes the nature good.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural view of the male joint of the present invention.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Examples

As shown in fig. 1, 2 quick-operation joint, including male joint and female joint, the male joint includes

plug

2, 2 integrated into one piece of plug, plug 2 rear portion is outside protrusion, two column structures around plug 2, the slope of plug 2 rear portion inner wall, the anterior inner wall of plug 2 is parallel with the central line, the anterior outer wall front end of plug 2 is sunken, the depressed part is equipped with the inclined plane, 2 middle part outer walls of plug are equipped with the stopping groove, female joint includes casing 1, the slope of casing 1 rear portion inner wall sets up, casing 1 front portion is equipped with steel ball 5, steel ball 5 is connected with overcoat 3, the overcoat cover is established at casing 1 outer wall, be equipped with overcoat spring 6 between overcoat 3 and casing 1. The diameters of the outer walls of the rear parts of the shell 1 and the plug 2 are increased from inside to outside, and the outflow speed is high.

An outer sleeve retainer ring 4 is arranged in front of the outer sleeve 3.

And a shell O-shaped ring 7 contacted with the front concave part of the plug 2 is arranged on the inner wall of the shell 1, so that the sealing property is improved.

When the plug is used, the plug 2 is inserted, the inner wall of the front part of the plug 2 is smooth, the large impact abrasion to the inside is avoided, the plug is shorter than a common joint structure, the speed is less affected, a valve core structure is not provided, the flow passage caliber is large, and the plug is suitable for large flow.
