Further, as a preferred embodiment, the connector holder 700 is further included, and the connector holder 700 is connected with the second interface 12. The connecting seat 700 comprises a connecting nozzle 710 and a connecting nut 720, the connecting nozzle 710 is fixedly connected with the connecting nut 720, the centers of the connecting nozzle 710 and the connecting nut 720 are overlapped, and the connecting nozzle 710 protrudes out of the connecting nut 720.
When the quick coupling is assembled, the claws 400 of the pressing cap 20 extend into the cavities 100 of the first connector 11 from front to back. During initial assembly, the rear part 620 of the locking part 600 of the jaws 400 firstly enters the insertion section 110, because the rear part 620 comprises the guide inclined plane 621, the outer diameter of the locking part 600 in a free state is larger than the inner diameter of the insertion section 110, but because the jaws 400 have certain elasticity, when the jaws 400 initially enter the cavity 100, a plurality of jaws 400 contract inwards, so that the locking part 600 draws close inwards, all the jaws 400 can smoothly enter the insertion section 120 under the guide of the guide inclined plane 621, and then the whole jaws 400 are pushed into the cavity 100 all the way backwards; when the locking part 600 of the jaw 400 enters the locking section 120, because the inner diameter of the locking section 120 is increased, after losing the constraint, the jaw 400 expands outwards under the action of self elasticity to recover the free state, and at this moment, the anti-falling boss 510 on the shaft 500 just crosses the limit boss 111, and the press cap 20 cannot be pulled out forwards under the mutual matching of the anti-falling boss 510 and the limit boss 111. I.e. the assembly of the quick coupling is completed. The quick connector is only provided with two parts, and during production, the quick connector is simple to assemble, the assembling and the processing of the quick connector can be completed by only one action, and the production efficiency is high.
In the assembled quick coupling, the pressing cap 20 can move back and forth relative to the main body 10 along the axis of the first connector within a small range. When the pressing cap moves forwards, when the anti-falling boss 510 abuts against the limiting boss 111, the pressing cap cannot move forwards continuously; when the pressing cap 20 moves backward, the pressing cap cannot move backward any more when the claws 400 abut against the inner wall of the cavity 100. At the same time, the front end surface of the main body 10 abuts against the back surface of the base plate 300, so that the pressing cap 20 cannot move backward any more.
When the quick connector is used, the second interface of the quick connector is installed with peripheral equipment, the peripheral equipment generally comprises a connector with external threads, the connecting nozzle of the connecting seat on the second interface is inserted into the connector of the external equipment, and then the nut is screwed, so that the peripheral equipment and the quick connector can be installed and connected. Then, the quick coupling of the connection pipe a (for example, a PU pipe) is inserted into the through hole 310, the connection pipe a passes through the jaw 400, and when the connection pipe a passes through the locking portion 600, since the inner circumference of the rear portion 620 is provided with the protrusion 623, the protrusion 623 abuts against the outer surface of the connection pipe a, and one end of the protrusion 623 is an inclined surface, at this time, the connection pipe a props the jaw 400 outwards, so that the connection pipe a can pass through the jaw 400 and enter the sealing section 130. The connection pipe is inserted forward until the connection pipe a reaches the end of the sealing section 130. Because the inner wall of the sealing section 130 is provided with the convex rib 131, the convex rib 131 tightly presses the outer surface of the connecting pipe a, and the convex rib 131 is directly and tightly contacted with the connecting pipe, thereby achieving a good air tightness effect.
And because the outer surface of the locking part 600 is in fit connection with the abutting inclined surface 122 of the locking section 120, after the claw 400 is spread, the outer surface of the locking part 600 always abuts against the abutting inclined surface 122, so that the protruding spine 623 of the locking part 600 keeps biting the outer surface of the connecting pipe a, and the connecting pipe a cannot be pulled out forwards. Moreover, when the connection pipe a is filled with a medium (e.g., air or water), the outer wall of the connection pipe a is pressed by the medium, so that the connection between the connection pipe a and the protrusion 623 is tighter. The connection pipe a is not movable back and forth with respect to the quick coupling because the front end of the connection pipe a is already pressed against the end surface of the sealing section 130. But the connection pipe a may be rotated with respect to the main body 10. Also, in the rotation, the pressing cap 20 can rotate with respect to the main body 10 along with the connection pipe a. Since the main body 10 and the pressing cap 20 are relatively connected by the limit between the outer surface of the locking portion 600 and the abutment slope 122, the mutual rotation between the two does not damage the surface of the connection pipe a. Thus, durability is improved.
When the connecting pipe a needs to be pulled out of the quick connector, the pressing cap is pushed backwards with force, so that the expanding inclined plane 622 of the rear part 620 of the locking part 600 of the pressing cap 20 is abutted to the tapered boss 121, and the claw 400 is expanded outwards by the tapered boss 121; since the rear end surface of the connection pipe a abuts against the end surface of the sealing section 130, when the pressing cap 20 moves backward, the connection pipe a is relatively stationary, and the jaws 400 are spread by the tapered bosses 121 when moving backward, so that the spurs 623 are separated from the connection pipe a. Since the protrusion 623 no longer bites the connection pipe a, the connection pipe a can be smoothly pulled out forward. After the connection pipe a is pulled out. The pressing cap 20 is loosened, and the jaw 400 is reset under the action of the self elasticity of the jaw 400. Waiting for the next insertion of the connection tube a.
The utility model provides a quick-operation joint, just having utilized ingeniously to insert the connecting pipe after, the connecting pipe struts the jack catch for the jack catch supports the internal surface of main part locking section, makes the connecting pipe can not be extracted. Thereby achieving the effect of quick installation. And during work, the high-pressure medium is contained in the connecting pipe, and the high-pressure medium can outwards expand the connecting pipe, so that the connecting pipe is more tightly engaged with the spurs of the clamping jaws, and the connecting pipe is more difficult to pull out. In a similar way, the quick coupling utilizes the convex rib to support the outer surface of the connecting pipe to realize sealing, and during work, the high-pressure medium can enable the convex rib to be more tightly connected with the outer wall of the connecting pipe, so that the sealing performance is better.
The quick connector of the application can be used for connecting general air pipes, or can be used for quickly connecting liquid pipes or gas pipes. Not only simple to operate, product long service life moreover seals effectually.
In this embodiment, the quick coupling is a corner-type coupling, and by setting the relative position of the first interface and the second interface, the quick coupling can be set to be a straight-through coupling, or some couplings can be added, so that the quick coupling can belong to a three-way coupling or a four-way structure.
Referring to fig. 7, in some embodiments, the base plate 300 may not be provided with a cuff.
Referring to fig. 8, in some embodiments, the inner surface of the sealing segment 130 is provided with a groove 132, the groove 132 is provided with a sealing ring 133, and the groove 132 and the sealing ring 133 form the sealing structure 200. When the smoothness of the outer surface of the connection pipe a is insufficient, a desired sealing effect may not be achieved by the rib. At this time, the sealing ring 133 may be added to the sealing section 130, and the sealing ring 133 abuts against the outer surface of the connection pipe a, thereby achieving a sealing effect. Alternatively still, in some embodiments, both the bead and the seal ring may be incorporated into the seal segment 130. Further improving the sealing performance of the main body and the connecting pipe.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
