Description

A kind of air hose quick coupling

Technical field

The utility model is related to pipe fitting interconnection technique fields, specifically, being to be related to a kind of air hose quick coupling.

Background technology

Pipe fitting is the fastening means between pipeline and pipeline, is the tie point that can be dismounted between element and pipeline, Indispensable key player is acted as in pipe fitting, it is one of two main composition parts of hydraulic pipeline, and pipe fitting belongs to Dismountable connecting element, normal stable connection, leakproofness strong, Sizes, the pressure loss be small, craftsmanship meeting for it Except requirement that can be good etc., it is necessary to meet that dismounting is convenient to be required.It is currently used for the pipe fitting of connection compressed air hose There are many, traditional pipe fitting needs adapter when being connect with hose, and easily loosening causes to fall off；Tradition does not have compensation performance Gasket be only used for positive pressure, under negative pressure easily mutually disengage cause to leak.

Therefore, in the prior art, adapter is needed, easily loosening causes to fall off；Tradition does not have the gasket of compensation performance It is only used for positive pressure, the problems such as causing leakage is easily disengaged mutually under negative pressure, designs a kind of air hose quick coupling, be current The technical issues that need to address.

Invention content

Goal of the invention：It is in view of the drawbacks of the prior art and insufficient, it solves in the presence of adapter is needed, easily loosening causes to fall off； The gasket that tradition does not have compensation performance is only used for positive pressure, easily disengages the problems such as causing leakage, application mutually under negative pressure People improves by repeatedly practice, devises a kind of air hose quick coupling.

Technical solution：In order to achieve the above-mentioned object of the invention, a kind of air hose quick coupling, including adapter body.

The adapter body includes tube head and pipe tail, and the adapter body casts for integral type, and the tube head surface is equipped with The safe hangnail of protrusion, the tube head are provided with claw along axial symmetry, and the claw is internally provided with card slot, is set inside the tube head It is natural rubber convex surface gasket seal to have convex surface gasket seal, the convex surface gasket seal.

Preferably, the pipe tail is fine and closely woven bellows tail.

Preferably, the spacing dimension between the claw is 40mm.

Preferably, the tip inlet of the pipe tail is set as smooth groove.

Preferably, the adapter body is made using chromium plating Copper alloy material.

Preferably, the adapter body carrying working pressure range is 40-100kg/cm2.

Advantageous effect：Compared with prior art, advantage is the utility model：

1, the utility model is equipped with claw, and adapter is not necessarily in connection；Safe hangnail design, raised safe hangnail are embedding Enter claw inner card cage, reinforces locking effect, avoid unexpected loosening.

2, the utility model is equipped with the gasket seal of intelligent compensation function, has excellent colloid ductility, it is ensured that even if Under condition of negative pressure, still close enough between the gasket of compression, sealing performance is fully protected.

3, the utility model pipe tail is fine and closely woven bellows tail, improves inside and withholds grip, it is ensured that withholds whole Stability and safety；The entrance is smooth, and band groove designs so that power more saves when connector enters hose, and fluid passes through Shi Liuliang biggers.

Specific implementation mode

Below by a most preferred embodiment, the technical program is described in detail, but the protection of the utility model Range is not limited to the embodiment.

As shown in Figure 1, 2, a kind of air hose quick coupling, including adapter body, the adapter body include tube head 1 and pipe Tail 4, the adapter body cast for integral type, and 1 surface of the tube head is equipped with the safe hangnail 7 of protrusion, and the tube head 1 is along axis pair Title is provided with claw 3, and the claw 3 is internally provided with card slot 6, and the tube head 1 is internally provided with convex surface gasket seal 2, the convex surface Gasket seal 2 is intelligent compensation viton rubber convex surface gasket seal.

The pipe tail 4 is fine and closely woven bellows tail.

Spacing dimension between the claw 3 is 40mm.

The tip inlet 5 of the pipe tail 4 is set as smooth groove.

The adapter body is made using chromium plating Copper alloy material.

The adapter body carrying working pressure range is 40-100kg/cm2.

The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
