Summary of the invention
In view of this, can be realized quick charging-discharging function, and have the present invention provides a kind of quick inflation/deflation connector
There is reliable leakproofness.
A kind of quick inflation/deflation connector, the connector include gas cylinder nut, metal washer, nut, spherical joint, filling mouth,
Sealing ring, nut and thimble；
The gas cylinder nut and nut cooperate together, and one end of the filling mouth is by axial limiting in nut
Portion, the metal washer are bonded with the filling mouth end face in nut；The inner cavity of the spherical joint and the inner cavity of filling mouth are mutual
Thimble is limited in the axially extending bore of filling mouth by perforation, the other end for loading mouth by nut, the cooperation of thimble and filling mouth
Cavity is provided with sealing ring；When inflation/deflation, after the connector of external gas cylinder is screwed in by gas cylinder nut thread, connector end face with
Metal washer contact, further screw make metal washer deformation occurs will filling mouth one end and it is extraneous seal, then thimble is applied
Axial force is added to open the valve of connector, compresses seal while thimble is mobile realizes the close of the filling mouth other end and the external world
Envelope, gas are exported through filling mouth inner cavity by spherical joint outward.
Further, the gas cylinder nut is step through-hole, and aperture is threaded hole, and macropore is unthreaded hole, and macropore is corresponding outer
Section is threaded on circle.
Further, the nut is lid-like, and the outer circle of the centre bore and filling mouth of nut is slidably matched, nut
Convex edge inner surface has the screw thread with the thread segment cooperation in gas cylinder nut outer circle.
Further, one end of the filling mouth is T-type structure, processes thread segment in the outer circle of the other end, loads mouth
Inner hole is divided into three sections, and the outer circle of middle section inner hole and thimble is slidably matched, and the inner hole and thimble of two sections of left and right are clearance fit.
Further, the thimble is elongated cylindrical structure, has an annular diameter on the periphery of cylindrical body
To boss.
The utility model has the advantages that
The extrusion deformation that the present invention is occurred after being contacted using metal washer with gas cylinder end face is come the gas circuit at sealed interface end, top
The movable end sealing of needle is realized by sealing ring, and synchronous sealed, the step of entire inflation/deflation are achieved that while pressing thimble
Rapid simple and sealed reliable, realizes the function of quick charge and discharge.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention
Wherein, 1- gas cylinder nut, 2- washer, 3- nut, 4- spherical joint, 5- load mouth, 6- sealing ring, 7- nut, 8-

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 1, the present invention provides a kind of quick inflation/deflation connector, the connector include gas cylinder nut 1, washer 2,
Nut 3, spherical joint 4, filling mouth 5, sealing ring 6, nut 7 and thimble 8；
Gas cylinder nut 1 is step through-hole, and aperture is threaded hole, and macropore is unthreaded hole, is machined with spiral shell in the corresponding outer circle of macropore
Line section.
Nut 3 is lid-like, and the outer circle of the centre bore and filling mouth 5 of nut 5 is slidably matched, the convex edge inner surface of nut
With the screw thread with the thread segment cooperation in gas cylinder nut outer circle.
The one end for loading mouth 5 is T-type structure, and thread segment is processed in the outer circle of the other end, and the inner hole of filling mouth 5 is divided into three
Section, middle section inner hole and the outer circle of thimble 8 are slidably matched, and the inner hole and thimble of two sections of left and right are clearance fit.
Thimble 8 is elongated cylindrical structure, has an annular radial boss on the periphery of cylindrical body.
Gas cylinder nut 1 and nut 3 are together by a threaded connection, and the one end for loading the T-type structure of mouth 5 is located in nut 3
Portion, the aperture of gas cylinder nut 1 for connect with gas cylinder, metal washer 2 be placed in gas cylinder nut 1 unthreaded hole it is interior and with the dress in nut
Fill out the T-type structure end face fitting of mouth 5；Spherical joint 4 is fixedly connected with the middle section of filling mouth 5, the inner cavity of spherical joint 4 and filling
The inner cavity of mouth 5 is interpenetrated, and the radial boss of thimble 8 is limited in filling mouth 5 by the other end for loading mouth 5 by nut 7
In one section on the right side of hole, sealing ring 6 is housed between the step surface of one section of inner hole of radial boss and right side；When inflation/deflation, external gas
After the connector of bottle is screwed in by gas cylinder nut, connector end face is contacted with metal washer, and further application, which screws power, makes metal
Deformation occurs for washer by filling 5 one end of mouth and extraneous sealing, and the valve of connector, top are then opened to the application of thimble 8 axial force
Compresses seal while needle 8 is mobile realizes that filling 5 other end of mouth and extraneous sealing, gas are defeated outward by spherical joint 4
Out.
