Sealing ring inside nonreturn valve core uses structure as shown in Figure 4, and sealing ring, which is only provided with, stretches into gas transmission plug endoporus
Lip, inner seal can only be realized, if the spliced eye of gas transmission plug outer wall and nonreturn valve core afterbody occurs between larger cooperation
During gap, then easy gas leakage, sealing effectiveness is poor.
The content of the invention
The purpose of this utility model is to provide a kind of air pump quick speed adapter, improves the sealing structure inside nonreturn valve core,
Sealing effectiveness is more preferable.
What the purpose of this utility model was realized in：A kind of air pump quick speed adapter, including the source of the gas being connected with source of the gas connect
Head, is threaded in the fast combination hub of gas source connector afterbody, and gas source connector is internally formed gas distribution channel with fast combination hub, and gas transmission is led to
In road be provided with nonreturn valve core, nonreturn valve core afterbody be provided with spliced eye, spliced eye intracavity bottom be provided with transfer port, pneumatic tool it is defeated
Gas plug inserts fast combination hub and head extend into spliced eye and realizes gas transmission, it is characterised in that：Bottom of chamber in the spliced eye
Portion is provided with O-ring seal, the O-ring seal surface provided with concentric outer lip and interior lip, outer lip and interior lip it
Between formed supply power driven tools gas transmission plug grafting annular slot, outer lip outer wall contradicted on spliced eye inwall.
It is preferred that, the bottom sidewall of the spliced eye is provided with annular slot, and the outer lip inlay card of O-ring seal is in annular
In neck, the thickness of outer lip is more than the depth of annular slot.
It is preferred that, the height of the interior lip is less than the height of outer lip.
It is preferred that, the outer lip inside top is provided with the first rounding.
It is preferred that, the interior lip inside top is provided with the second rounding.
It is preferred that, the convex lip thickness is less than evagination lip thickness.
It is preferred that, the O-ring seal endoporus bottom opening is provided with the 3rd rounding.
It is preferred that, the O-ring seal diameter of bore is more than or equal to the diameter of transfer port.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1st, by setting outer lip and convex bead structure, two way seal is realized, sealing effectiveness is more preferable.
2nd, annular slot is preferably fixed to O-ring seal.
3rd, preferable guiding centering effect, convex bilabial are played in insertion of the first rounding in outer lip to gas transmission plug
Degree is less than evagination bilabial degree so that outer lip being capable of preferentially centering, it is ensured that interior lip can more effectively extend into gas transmission plug
Endoporus.
4th, O-ring seal diameter of bore reduces gas transmission resistance more than or equal to the diameter of transfer port.
