Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.
As shown in figures 1-4 it is one embodiment:
A kind of rotatable gas-tpe fitting, including connector 3, connector 3 are connect with tracheae 1.Traveling nut 2 is from the end II of connector 3
In indentation to slot 3-4.The pressing part 2 of traveling nut 2 is equipped with chamfering 2-1, and corresponding joint area is equipped with guide frame 3-3.
When traveling nut 2 bears certain pressure, traveling nut 2 and 3 corresponding position of connector have certain deformation, are packed into traveling nut
In the slot 3-4 of connector 3.Traveling nut 2 and 3 cooperation position of connector radially and are axially having gap 5, therefore, traveling nut 2
It can rotate freely, and connector 3 will not be rotated with it with tracheae 1.
When connector 3 is connect with air pump gas outlet, rotating nut, the block reinforcement 3-1 outer diameter on connector 3 is greater than traveling nut 2
Internal diameter, therefore connector 3 and tracheae 1 can be fixed in air pump outlet by nut 2.Groove 3-2 is provided on connector 3, to assemble
Sealing ring 4 guarantees leakproofness when inflation.
As Fig. 5~6 show second embodiment:
The embodiment and one embodiment the difference lies in that connector 3 uses 4 end face seal after connecting with air pump.
The block reinforcement 3-1 of connector 3 is provided with slot 3-2 in axial end face, to fixed seal ring 4.
As Fig. 7~12 show third embodiment:
The embodiment and first, second embodiment are the difference lies in that nut 2 enters in slot 3-4 from the II side pressure of connector 3.
Shown in Fig. 9, the pressing part 2-2 of nut 2 is splitted structure, and valve quantity is divided to be greater than 2.Pressing part 2-2 is equipped with groove 2-2-
1, in stress, it is more advantageous to deformation, therefore interference big as far as possible can be designed in structure.Guiding is provided on pressing part 2-2
Chamfering 2-1.
Nut 2 shown in Figure 12, pressing part 2-2 are overall structure, are also provided with groove 2-2-1 and guiding chamfering above
2-1.Due to for overall structure, deflection is smaller when stress, therefore magnitude of interference also can be smaller.
The corresponding pressing part of connector 3 is equipped with guide frame 3-3, in the fluted 3-2 in the upper end of connector 3, to assemble
Sealing ring.The lower part of the mating groove 3-4 is equipped with block reinforcement 3-1, and the block reinforcement outer diameter is greater than the internal diameter of traveling nut.
When nut 2 is forced outwardly, due to the structure of nut pressing part, make the cooperation interference of nut 2 Yu connector 3
Amount becomes larger, therefore nut 2 will not reversely fall off.
It should be understood that these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.This
Outer to should be understood that after reading the content taught by the present invention, those skilled in the art can make the utility model each
Kind change or modification, these equivalent forms also fall within the scope of the appended claims of the present application.
