Specific implementation mode
To further illustrate that each embodiment, the utility model are provided with attached drawing.These attached drawings are in the utility model discloses
A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain that the running of embodiment is former
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 4, the utility model provide a kind of inflation/deflation gas nozzle, including a columnar connection mouth seat 1 with
And a spiral cover 2, there is one first venthole 10, the first venthole 10 to run through from the middle part of connection mouth seat 1 on the connection mouth seat 1
Entire connection mouth seat 1, gas port 10a is located at mounting object 4 one of in two gas ports (10a and 10b) of the first venthole
Inside, another 10b are located at outside mounting object 4, and connection inside and outside mounting object is got up, realizes the purpose of inflation/deflation.
With reference to figure 1- Fig. 4, the spiral cover 2 is threadedly coupled with connection mouth seat 1, and installation pair will be located at by having in the spiral cover 2
As the sealing 20 that the gas port 10a outside 4 is sealed, also there is at least one second venthole 22 on the spiral cover 2, when the sealing
When portion 20 is detached with the gas port 10a outside mounting object 4, second venthole 22 is connected to the first venthole 10.By
It is to be threadedly coupled, therefore when spiral cover is toward backspin, sealing 20 is moved towards the top surface of connection mouth seat 1 with connection mouth seat 1 in spiral cover 2
Dynamic, when the top surface of sealing 20 and connection mouth seat 1 offsets, sealing blocks the first venthole 10 so that in mounting object 4
Portion is isolated from the outside, and keeps the air pressure inside mounting object 4；When spiral cover up revolves, sealing 20 is towards far from connection mouth seat 1
Top surface is moved, and sealing 20 is detached with the gas port 10a outside mounting object 4, second venthole, 22 and first venthole 10
Connection so that be in communication with the outside inside mounting object 4, then can carry out the operation of inflation/deflation.
With reference to figure 1- Fig. 4, also there is a flange 12, the flange 12 to be located at installation pair on the side wall of the connection mouth seat 1
In 4, to prevent connection mouth seat 1 from deviating from from mounting object 4, one first gasket 30 is also socketed on the connection mouth seat 1,
The bottom surface of the spiral cover 2 can be directly in sealing contact with first gasket 30, and spiral cover and the first gasket are directly in sealing contact,
So that when rotation spiral cover, spiral cover will not rub mounting object 4, thus be not in because friction causes mounting object 4 damaged,
The problem of causing gas leakage.
With reference to figure 2 and Fig. 4, as a preferred embodiment of the present embodiment, the top surface of the connection mouth seat 1 is equipped with a ring
Around the first annular groove 14 of the first venthole 10, the second gasket 32 is installed in the first annular groove 14, it is described close
Envelope portion 20 can be in sealing contact with the second gasket 32, to increase its leakproofness.
With reference to figure 1, Fig. 2 and Fig. 4, as another preferred embodiment of the present embodiment, the bottom surface of the connection mouth seat 1 is equipped with
Multiple extension columns 50, multiple rings for extending the interval of column 50 are located at around the first venthole 10 and a baffle 52, described
Baffle 52 is fixedly connected with the free end for extending column 50, and the gas port 10b inside mounting object is sheltered from, that is, is entered
To the gas being either discharged out of mounting object 4 in mounting object 4 be between multiple extension columns 50 gaps discharge or
Enter, article (such as some fillers) in mounting object will not between and gas port 10b be in direct contact, therefore be not in
The case where gas port 10b is blocked.
With reference to figure 2 and Fig. 4, as the another preferred embodiment of the present embodiment, also have on the side wall on 1 top of connection mouth seat
There is a second annular groove 16, there is the ring rib 24 to match with second annular groove, annular on the inner wall of the spiral cover 2
Boss 24 can be stuck in second annular groove 16, and can be moved up and down in second annular groove 16, therefore be unscrewed
When lid 2, spiral cover 2 can also ensure to link together with connection mouth seat 1 always, will not lose spiral cover 2.
With reference to figure 1 and Fig. 3, also it is equipped with as the further optimisation of the present embodiment, on the outer wall of the spiral cover 2 several
A rib 26 protruded outward, in order to turning for spiral cover 2.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
