Abstract
The utility model relates to an air cock of an inflator. Mainly, the utility model is provided with one free-moving piston inflator; the inner wall surface of an air outlet of one end of the piston inflator forms one flange; one airtight pad is arranged in the air outlet; the inner wall surface of the air outlet forms inner screw corresponding to the outer screw of a ball needle; one concave ring corresponding to the convex flange is arranged on the periphery surface of the airtight pad; the airtight pad has the fixing efficiency directly through the match of the convex flange and the concave ring. The air cock of an inflator which can save the assembling time and cost expenses caused by few parts can be provided.
Description
Technical field
The utility model mainly relates to a kind of pump air valve device, especially a kind ofly directly is provided with the internal thread that can cooperate an inflator at the valve place of pump, and be provided with a flange at the inside of valve wall, with assembling one air packing that can be certain.
Background technique
Press, general inflator structure mainly can be by Fig. 3 shown in the drawings and shown in Figure 4; Wherein, visible and this existing pump is to have a cylinder 50, an air packing 60, a metal ring 70 and an inflator 80, and this inflator 80 is to be a ball pin in present embodiment.
End at cylinder 50 is to be provided with an air outlet hole 51, and then is formed with a flange 52 between air outlet hole 51 and barrel, in addition, then is to have a piston that can be free to slide 53 in the inside of cylinder 50.
Air packing 60 is directly to be inserted within this air outlet hole 51, and is to have a carrier ring 61 corresponding to this flange 52 in the end of its outer circumferential face.
One end of ball pin 80 is the outside threads 81 that are formed with corresponding to this metal ring 70 internal threads 71.
When above-mentioned existing pump made up, this air packing 60 was directly to be inserted within this air outlet hole 51, and by the relation between this carrier ring 61 and this flange 52, this air packing 60 is an inside at air outlet hole 51 firmly.Thereafter, 70 of this metal rings are forced within the air outlet hole 51 in the mode of forcing, make this metal ring 70 and the inner face of air outlet hole 51 between form and connect airtight.Thereafter, the user then can utilize the internal thread 71 that is arranged on metal ring 70 inside and be arranged on screwing togather mutually of 81 of ball pin 80 end outside threads ball pin 80 is assembled within the cylinder.
Because need in the above-mentioned assembling process and will reach four elements: for example cylinder 50, air packing 60, metal ring 70 and ball pin 80 fit together, so not only expend the considerable time, and also because when assembling metal ring 70 and cylinder 50, need special instrument to reach desired purpose, so on cost, also need extra expenditure.
Therefore, the practicability of above-mentioned traditional type existing structure is not good, and the necessity that is improved is arranged.
This creator deeply conceives at the shortcoming of above-mentioned existing structure, and the road of active research improvement, and through long-term effort, study and develop, design the utility model.
The model utility content
Main purpose of the present utility model, be to be to provide a kind of pump air valve device, it not only can save the time of assembling because of the minimizing of element, more can save as the process that is forced into as existing, so also saved many on the expenditure of cost because of the utility model.
For reaching this purpose, pump air valve device of the present utility model mainly is that the internal face at air outlet hole is provided with internal thread, and is provided with a flange in addition at wall place, the inside of air outlet hole.Simultaneously, be provided with a scrobicular ring corresponding to this flange, so then can directly air packing be given clamping by this flange at the ring side face of air packing.Moreover inflator is to can be the flexible pipe that a ball pin or has holding device.
Description of drawings
Can further understand feature of the present utility model and essence effect thereof, content for ease of the auditor, after being described in more detail in below in conjunction with drawings and Examples, wherein:
Fig. 1 is a plane of the present utility model view sub-anatomy;
Fig. 2 is the floor map of pump of the present utility model after assembling, and wherein, cylinder and air packing are to show with sectional view;
Fig. 3 is the plane exploded view of existing pump; And
Fig. 4 is the floor map of pump shown in Fig. 3 after assembling.
Embodiment
See also the appended graphic Fig. 1 of the utility model and Fig. 2, wherein, as seen reaching pump air valve device of the present utility model is to have comprised a cylinder 10, an air packing 20 and an inflator 30, and this inflator 30 is to be a ball pin in present embodiment.
End 10 of cylinders is to be provided with an air outlet hole 11, and be formed with internal thread 12 at the inner peripheral surface of air outlet hole 11, simultaneously then then being formed with a flange 13 between air outlet hole 11 and barrel, in addition, then is to have a piston that can be free to slide 14 in the inside of cylinder 10.
Air packing 20 is directly to be inserted within this air outlet hole 11, and has one and the air channel 21 that is connected of this air outlet hole 11, then has a scrobicular ring 22 corresponding to this flange 13 at its outer circumferential face.
One end of ball pin 30 is the outside threads 31 that are formed with corresponding to this internal thread 12.
Inflator structure shown in the utility model then can directly be assembled in this air packing 20 this flange 13 places in the group device, and cooperatively interacts 20 closely clampings firmly by this flange 13 of this air packing by this flange 13 and this scrobicular ring 22.Thereafter, but then be with this ball pin 30 by corresponding to the outside thread 31 of this internal thread 12 spiral in these air outlet hole 11 places, and and then compressing live this and put air packing 20 in this air outlet hole 11 inside, so, then not only finished assembling, and also finished and prevent that this air packing 20 from dropping out this air outlet hole 11 and reaching airtight effect by this air packing 20 of direct compressing of ball pin 30.
In the existing structure, the effect of this metal ring 70 still can more can directly not oppressed air packing 60 by its existence and prevent dropping out of air packing 60, and reach airtight effect simultaneously in conjunction with this ball pin 80.Review the utility model, owing to air packing 20 is directly to reach fixing effect by cooperatively interacting of 22 of flange 13 and scrobicular rings, simultaneously, 20 of air packings are to reach airtight effect by the direct compressing of this ball pin 30, so can omit the metal ring 70 in the known structure.
The utility model can be saved the time of assembling because of the minimizing of element, more can be because of having saved as the process that is forced into as commonly using, so also saved many on the expenditure of cost.
