Embodiment
Below, the utility model is specifically described by exemplary embodiment.It should be appreciated, however, that do not having
In the case of being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations
In mode.
, it is necessary to explanation in description of the present utility model, term " interior ", " outer ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right" are the position relationship shown in based on accompanying drawing 1, are for only for ease of and describe this hair
It is bright and simplify description, rather than instruction or imply that signified device or element must have specific orientation, with specific orientation
Construction and operation, therefore be not considered as limiting the invention.In addition, term " first ", " second " are only used for describing purpose,
And it is not intended that instruction or hint relative importance.
With reference to figure 1, a kind of air hose coupling, for being connected with mating connector 3, the air hose coupling includes body 1,
The body 1 includes first mouth of pipe 11 being engaged with mating connector 3, is provided with first mouth of pipe 11 and positions the cooperation
The keeper 2 of connector, the keeper 2 include being set in the mating connector 3 to guide the mating connector 3
So that the location division 21 that first mouth of pipe 11 aligns with the mating connector 3, and managed located at the location division 21 and first
Between mouthfuls 11, the limiting section 22 of the radial motion of mating connector 3 can be limited.
Referring to figs. 1 to Fig. 3, the body 1 includes first mouth of pipe 11, second mouth of pipe 12 and clamping part 13, the first screw thread
14th, the second screw thread 15, locking nut 16 and seal 17.First mouth of pipe 11 is provided with is engaged cooperation with mating connector 3
End face, herein, in order to be connected with former connector, to be set with 3 identical end face of mating connector at first mouth of pipe 11
There is seal 17 in order to the seal face after air hose coupling connection, prevent from leaking out.Outer wall at second mouth of pipe 12
Provided with the external screw thread being engaged with train line 5, i.e. the second screw thread 15, in order to second mouth of pipe 12 and the train line
5 are fixedly connected, and between the clamping part and second screw thread 14, the locking nut 16 is provided with first screw thread 14
The screw thread being engaged with second screw thread 14, in order to which air hose coupling is fixed on into phase when installing the air hose coupling
In the fixed plate answered.The clamping part 13 is the bolt shape structure being fixed on the body 1, with the integral type of body 1
Shaping when dismounting the air hose coupling using instrument in order to be clamped, so as to fasten or dismantle the airduct connection
Device.
The keeper 2 is integrated with the consolidation of body 1, and the keeper 2 includes location division 21, limiting section 22, described fixed
