Description
Technical field
The utility model is related to pipe fitting interconnection technique fields, specifically, being to be related to a kind of preventing for air hose quick coupling
Dirt lid.
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.Pipe fitting for connecting compressed air hose has more
Kind, in the end of compressed air pipe fitting, we can see a kind of boring cover, primarily serve, blocking work dust-proof to fire protection pipeline
With, this kind of boring cover, the problems such as easily loosening causes to fall off, and poor sealing easily causes leakage, and there are security risks.
Therefore, in the prior art, easily loosening causes to fall off, and poor sealing easily causes leakage, and there are security risks etc. to ask
Topic, designs a kind of dustproof cover of air hose quick coupling, is the current 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 easily to loosen causes to fall off, poor sealing, easily
It causes to leak, the problems such as security risk, applicant improves by repeatedly practice, devises a kind of the dust-proof of air hose quick coupling
Lid.
Technical solution：In order to achieve the above-mentioned object of the invention, a kind of dustproof cover of air hose quick coupling, including lid, institute
The lower section for stating lid is provided with fixed pin along axial symmetry, and circular aperture is offered on the fixed pin, and the cover outer surface is set
There are the safe hangnail of protrusion, the top of the lid that axial symmetry is provided with claw, the claw offers card slot, the lid
It is internally provided with convex surface sealing element, the convex surface sealing element is intelligent compensation natural rubber or viton rubber convex surface gasket seal.
The fixed pin is triangle fixed pin.
The lid is made using chromium plating copper alloy or high density stainless steel alloy material.
The compressive resistance of the lid is 60-120kg/cm2.
Advantageous effect：Compared with prior art, advantage is the utility model：
1, the utility model claw, the design of safe hangnail, reinforce locking effect, avoid unexpected loosening；Equipped with intelligent benefit
The gasket seal of function is repaid, there is excellent sealing performance.
2, the utility model is provided with triangle fixed pin along axial symmetry, can securely fix lid, prevents lid quick-fried
Fly, injures personnel by a crashing object.

Fig. 2 is a kind of present invention looks up structural representation of the dustproof cover of air hose quick coupling.
Fig. 3 is a kind of overlooking structure diagram of the dustproof cover of air hose quick coupling.
In figure：1, lid；2, fixed pin；3, claw；4, convex surface sealing element；5, card slot；6, safe hangnail.
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, a kind of dustproof cover of air hose quick coupling, including lid 1, the lower section of the lid 1 is along axis pair
Title is provided with fixed pin 2, and circular aperture is offered on the fixed pin 2, and 1 outer surface of the lid is equipped with the safe hangnail of protrusion
6, the top of the lid 1 is provided with claw 3 along axial symmetry, and the claw 3 offers card slot 5, and the lid 1 is internally provided with convex
Face seal 4, the convex surface sealing element 4 are intelligent compensation natural rubber or viton rubber convex surface gasket seal.
The fixed pin 2 is triangle fixed pin.
The lid 1 is made using chromium plating copper alloy or high density stainless steel alloy material.
The compressive resistance of the lid 1 is 60-120kg/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.
