Detailed Description
For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:
as shown in fig. 1 to 5, a quick connector for an air pipe comprises a female connector 1 and a male connector 2, wherein the female connector 1 is a hollow pipe, a first air pipe connecting part 11 is arranged at the top end of the female connector 1, a first horse-tooth buckle 12 is arranged on the outer side of the first air pipe connecting part 11, a stepped hole 13 is arranged on the inner side of the bottom end of the female connector 1, and a plurality of clamping blocks 14 are convexly arranged on the outer side of the bottom end of the female connector 1; male joint 2 is the hollow tube, 2 bottoms of male joint are equipped with second trachea connecting portion 21, the outside of second trachea connecting portion 21 is equipped with second horse tooth and detains 22, 2 coaxial protruding be equipped with in top of male joint with 13 clearance fit's of shoulder hole joint pipe 23, the annular 24 of three installation sealing washer 3 is seted up to the lateral wall of joint pipe 23, 2 tops of male joint are protruding still be equipped with the engaging lug 25 of a plurality of fixture block 14 one-to-one, all be equipped with open slot 26 on every engaging lug 25, the relative male joint 2 of open slot 26 radially offers, open slot 26 cooperates with the 14 joint of fixture block.
Two clamping blocks 14 are arranged; the side wall of the open slot 26 is provided with a limit convex strip 27 matched with the clamping block 14 in a stopping way, and the clamping block 14 can be accommodated between the slot bottom of the open slot 26 and the limit convex strip 27; the connecting lugs 25 are circular arc-shaped, and the two connecting lugs 25 are arranged in central symmetry with the axis of the male connector 2.
Specifically, the supporting ribs 28 are integrally arranged on the outer edges of the open grooves 26, and the supporting ribs 28 are used for connecting the open grooves 26 and the tops of the male connectors 2, so that the strength of the connecting lugs 25 is improved, and breakage is avoided.
The utility model discloses a concrete theory of operation as follows: when the device is installed, the air pipe is respectively sleeved on the first air pipe connecting part 11 and the second air pipe connecting part 21, and then the air pipe is fixed through an iron wire or a limiting ring or other fixing structures; when the matched male connector 2 and the matched female connector 1 need to be connected, the connector tube 23 is inserted into the stepped hole 13 correspondingly, and the fixture blocks 14 and the connecting lugs 25 are distributed in a staggered manner in the insertion process; after the connector pipe 23 is inserted in place, the female connector 1 is rotated relative to the male connector 2, so that the clamping block 14 slides along the open slot 26, in the sliding process, the clamping block 14 firstly abuts against the limiting convex strip 27, at the moment, the connection lug 25 is continuously rotated with force, elastic deformation is generated, the limiting convex strip 27 passes through until the clamping block 14 is clamped into the slot bottom, the limiting convex strip 27 is restored to the original position and limits the clamping block 14 to slide out, and therefore connection of the male connector 2 and the female connector 1 is completed.
