Abstract
The invention discloses a kind of air hose quick couplings, including adapter body, the adapter body includes tube head and pipe tail, the adapter body is cast for integral type, the tube head surface is equipped with the safe hangnail of protrusion, the tube head is provided with claw along axial symmetry, the claw is internally provided with card slot, the tube head is internally provided with convex surface gasket seal, the convex surface gasket seal is natural rubber convex surface gasket seal, the pipe tail is fine and closely woven bellows tail, and the tip inlet of the pipe tail is set as smooth groove.The safe hangnail design of the present invention, strengthens locking effect, avoids unexpected loosening；Gasket seal equipped with intelligent compensation function has excellent sealing performance；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, band groove design so that power more saves when connector enters hose, and fluid by when flow bigger.
Description
Technical field
The present invention relates to pipe fitting interconnection technique field, 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 the convenient requirement of dismounting.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 come 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 come off；Tradition does not have the gasket of compensation performance
Positive pressure is only used for, 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：In view of the drawbacks of the prior art and insufficient, solving to exist needs adapter, and easily loosening causes to come 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 is cast 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
There is convex surface gasket seal, the convex surface gasket seal is natural rubber 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, the present invention advantage is：
1st, the present invention is equipped with claw, in connection without adapter；Safe hangnail design, raised safe hangnail insertion card
Pawl inner card cage strengthens locking effect, avoids unexpected loosening.
2nd, the present invention is equipped with the gasket seal of intelligent compensation function, has excellent colloid ductility, it is ensured that even if negative
Under the conditions of pressure, still close enough between the gasket of compression, sealing performance is fully protected.
3rd, pipe tail of the present invention is fine and closely woven bellows tail, improves inside and withholds grip, it is ensured that withholds whole stabilization
Property and safety；The entrance is smooth, band groove design so that power more saves when connector enters hose, and fluid by when flow
Measure bigger.

Specific embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection scope of the present invention
It 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 includes tube head 1 and pipe
Tail 4, the adapter body are integral type casting, and 1 surface of 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 present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
