Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-5 is please referred to, the present invention provides a kind of technical solution:
A kind of air braking system nylon three-way quick-plugging joint, including nylon connector 1, nylon ring tail 2 and connection valve 3,
Nylon connector 1 is flexibly connected with nylon ring tail 2, and 1 activity of nylon connector is plugged in connection valve 3, on nylon connector 1
Offer circlip groove 4, circlip groove 4 cooperates with circlip 18 so that nylon connector 1 is closely connect with connection valve 3, Buddhist nun
Imperial connector 1 is connected separately with inner tube 5 and outer tube 6 far from 4 side of circlip groove, if offering dry seal circular groove 7 in inner tube 5,
It is arranged with sealing rubber ring 8 on sealing circular groove 7, offers deep groove 9, shallow grooves 10, deep groove 9 and scrobicula on outer tube 6 respectively
For installing sealing ring additional in slot 10, by the cooperation of sealing ring and nut seat 17 to guarantee the airtight of the nylon quick connector
Property, several crushing block putting holes 11 are also provided on outer tube 6, and crushing block 12 is movably installed in crushing block putting hole 11, this
Crushing block 12 in embodiment is movably arranged in crushing block putting hole 11 by shaft, and crushing block 12 can be put around crushing block
It sets the shaft in hole 11 to be rotated so that crushing block 12 can cooperate with extrusion fit slot 19, crushing block 12 is close to inner tube
5 bottom sides are fixedly installed with cooperation spring 13, by cooperation spring 13 to squeeze crushing block 12, so that crushing block
12 can open to guarantee that it can be with 19 close fit of extrusion fit slot in connection valve 3 under the action of no external force, this
Kind of design is so that nylon connector 1 and connection valve 3 cooperate from merely to stir far from 3 side of connection valve can not be by nylon connector
1 and connection valve 3 separated, when needing to extract nylon connector 1, need nylon ring tail 2 to close to 3 side of connection valve
It is squeezed, the mobile connecting insertion 14 for driving connection of nylon ring tail 2 moves forward, and the Forward of connecting insertion 14 drives spacing edge-cut 22
Forward squeezes crushing block 12 so that the part that crushing block 12 is caught in extrusion fit slot 19 is taken off using spacing edge-cut 22
From, nylon connector 1 and connection valve 3 could be separated at this time, nylon ring tail 2 include connecting insertion 14 and two nylon
Pipe-in-pipe 15 guarantees that the air-tightness connecting, connection valve 3 include valve body with the close fit of inner tube by connecting insertion 14
16, nut seat 17 and circlip 18, bogey of the valve body 16 as each component of connection valve 3, in being opened up on the inside of valve body 16
The screw thread opened up on the outside of screw thread and nut seat 17 carries out threaded engagement, and then the limit of circlip 18 is passed through circlip in valve body 16
18 with the cooperation of circlip groove 4 so that nylon connectors 1 and connection valve 3 are attached, 17 inner wall of nut seat is also provided with
The extrusion fit slot 19 cooperated with crushing block 12 prevents nylon from connecting by extrusion fit slot 19 with the cooperation of crushing block 12
Body 1 surprisingly falls off from connection valve 3；
The connecting insertion 14 of nylon ring tail 2 is inserted into the inner tube 5 of nylon connector 1, in the inner tube 5 of nylon ring tail 2
Wall is also provided with internal screw thread, internal screw thread and 20 threaded engagement of screw shackle being set on connecting insertion 14, is connected by screw thread
Ring 20 is connect to which nylon ring tail 2 to be attached with nylon connector 1, is also arranged on connecting insertion 14 and squeezes spring 21,
Spring 21 is squeezed for limiting to nylon ring tail 2,21 one end of spring is squeezed and is fixedly connected with screw shackle 20, squeezed
Spring 21 is fixedly connected far from 20 one end of screw shackle with the spacing edge-cut 22 of connecting insertion 14, when needing to make nylon connector
1 with connection valve 3 when separating, and nylon ring tail 2 is pushed to move it to close to connection valve side, squeezes 21 quilt of spring at this time
It stretches to generate restoring force, when external force disappears, nylon ring tail 2 is under the promotion for squeezing spring 21 to far from connection valve 3
Side is moved, to guarantee to remain open configuration when crushing block is under no external force；
The circlip groove 4 of nylon connector 1 and 18 activity of circlip in connection valve 3 cooperate, crushing block 12 and nut seat 17
The 19 activity cooperation of extrusion fit slot of inner wall, forms level-one locking mechanism by the cooperation of circlip 18 and circlip groove 4, leads to
Crushing block 12 and the cooperation of extrusion fit slot 19 are crossed to form secondary lock mechanism, such design so that nylon connector with connect
Valve 3 is connected even closer and will not voluntarily be fallen off.
It preferably as one, can be with by chamfered edge 23 if offering arterial highway chamfered edge 23 respectively in two nylon pipe-in-pipes 15
So that the nylon tube of insertion thereon will not fall off easily, to guarantee the normal work of entire air braking system.
As one, preferably deep groove 9 is provided with black sealing ring 24, and shallow grooves 10 are provided with red sealing ring 25, leads to
It crosses the red sealing ring 24 of the installation in shallow grooves 9 and provides visual guide to be mounted in connection valve 3 for nylon connector 1, it will
In the connector insertion nut seat 17 of nylon connector 1, can hear it is apparent " clickly " sound, red sealing ring 24 is invisible at this time,
It proves connector grafting in place, that is, can guarantee that switching performance ensures that sealing performance.
Preferably as one, 11 quantity of crushing block putting hole on outer tube 6 is 4 and is uniformly arranged around the interval of outer tube 6,
Cooperate 4 crushing blocks 12 by 4 crushing block putting holes 11 so that 12 stability under loading of crushing block, guarantees crushing block 12 and squeeze
The stability that press-fit slot 19 connects.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
