Fig. 3 is an exploded view of the present utility model.
Detailed Description
In order to provide a better understanding of the present utility model, the present utility model will be further described in detail with reference to the drawings and embodiments.
As shown in fig. 1, when the conventional clamping and pressing type pipe joint is connected, the joint is inserted into a pipe and matched with an external nut, so that the pipe and the joint have better sealing and fastening effects. However, it can also be seen from the figure that the pipe joint can obviously reduce the inner diameter of the pipe at the joint, and influence the flow rate of the pipe.
A quick connector as shown in fig. 2-3, which comprises a quick connector main body 1, wherein a check collar 6, a flat gasket 7 and a first sealing ring 8 are sequentially arranged inside one end of the quick connector main body 1 from inside to outside, and the check collar 6 and the flat gasket 7 are preferably made of metal. The quick connector body 1 is further connected with a nut 9 in a threaded manner, a pressing piece 91 extending into the quick connector body 1 is arranged on the inner side of the nut 9, and the pressing piece 91 presses the first sealing ring 8, the flat gasket 7 and the check collar 6 along with the tightening of the nut 9. The inner wall of the non-return collar 6 is provided with a latch 61 inclined toward the inside of the quick connector body 1, and when the pressing piece 91 presses the non-return collar 6 downward, the latch 61 can clamp the outer wall of the pipe 99 to be connected, thereby preventing the pipe 99 to be connected from being separated from the quick connector body 1. The pressing member 91 may have a ring shape and be integrally formed with the nut 9. The end of the quick connector body 1 far away from the screw cap 9 can be a threaded connection end, and the threaded connection end is used for connecting another pipeline; the end of the quick connector body 1 remote from the nut 9 may be other conventional connection structures or pipe elements.
As a preferable scheme, an annular mounting groove 12 is formed in the inner wall of the quick connector main body 1, and a second sealing ring 5 is mounted in the annular mounting groove 12. The design of the first sealing ring 8 and the second sealing ring 5 can play a double sealing role, and the sealing performance is further improved.
As still another preferable scheme, the quick connector further comprises a bushing 3 installed in the pipe 99 to be connected, the outer diameter of the bushing 3 is matched with the inner diameter of the pipe 99 to be connected, and one end of the pipe 99 to be connected is inserted into the quick connector body 1 together with the bushing 3. The liner 3 one end is provided with the spacing collar 31 that is located the pipeline that waits to connect outward, and spacing collar 31 can with liner 3 integrated into one piece, and when installing liner 3, spacing collar 31 can play the help operator and install liner 3 in place, and when waiting to connect the one end of pipeline 99 to insert in the quick-connect joint main part 1 simultaneously, liner 3 can obtain the extrusion of waiting to connect pipeline 99 and quick-connect joint main part 1 and fix.
When the pipeline connection is performed, the bushing 3 is inserted into one end of the pipeline 99 to be connected, and one end of the pipeline 99 to be connected is reinforced through the bushing 3. Then, unscrewing the screw cap 9, inserting one end of the pipe 99 to be connected into the quick connector body 1, then screwing the screw cap 9, and pressing the first sealing ring 8, the flat gasket 7 and the check collar 6 by the pressing piece 91 on the screw cap 9, so that the first sealing ring 8 is deformed to play a sealing role, and simultaneously, the latch 61 on the check collar 6 is deformed and clamps the outer wall of the pipe 99 to be connected, so that the pipe 99 to be connected is prevented from being separated.
