Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5 This utility model provides a pipe connector for quick connection, including a left connector 1 and a right connector 2. The left connector 1 has a left internal thread 3 on its left inner side and a left external thread 4 on its right outer side. The right connector 2 has a right internal thread 5 on its left inner side and a right external thread 6 on its right outer side. The left external thread 4 and the right internal thread 5 are threaded together. An external clamp 7 is fixedly installed on the left outer side of the right connector 2. The external clamp 7 is integrally formed with the right connector 2. The card holder 7 has an annular groove 8. An annular plate 9 is fixedly installed on the outer right side of the left connector 1. An annular frame 10 is fixedly installed on the right side of the annular plate 9. The annular frame 10 and the annular groove 8 are engaged with each other. This structure allows the user to quickly and stably connect the left connector 1 and the right connector 2. After connection, the annular plate 9 and the side wall of the outer card holder 7 are on the same annular surface. The left connector 1 and the right connector 2 are provided with auxiliary installation mechanisms. The structure of the auxiliary installation mechanisms improves the stability and sealing of the connection between the left connector 1 and the right connector 2.

[0027] Furthermore, such as Figure 1 and Figure 3As shown, an inner support ring 11 is fixedly installed on the left side of the inner side of the right connector 2, and a sealing gasket 12 is fixedly installed on the right end of the left connector 1. After the connection, the inner support ring 11 and the sealing gasket 12 of the pipe connector fit together. When the left external thread 4 and the right internal thread 5 are fully threaded, the sealing gasket 12 on the right end of the left connector 1 fits tightly with the inner support ring 11 on the inner side of the right connector 2, thereby improving the sealing performance of the connection between the left connector 1 and the right connector 2.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, the auxiliary installation mechanism includes a positioning groove 13 on the right side of the external card holder 7, a detachable kit 14 on the right connector 2, a positioning ring 15 fixedly installed inside the right side of the kit 14, the positioning ring 15 engaging with the positioning groove 13, a plurality of right screw holes 16 evenly provided on the left side of the kit 14, and a left positioning component detachably installed on the left connector 1. The auxiliary installation mechanism improves the stability and sealing of the connection between the left connector 1 and the right connector 2, and facilitates operation by the user.

[0029] Furthermore, such as Figure 1 and Figure 5 As shown, a pad 17 is fixedly provided on the inner wall of the kit 14. The pad 17 fits against the side wall after the ring plate 9 and the external card holder 7 are connected. The pad 17 is made of silicone. Through this structure, the side wall of the ring plate 9 and the external card holder 7 are sealed, which improves the stability of the connection between the left connector 1 and the right connector 2 on the one hand, and improves the sealing performance of the connection between the left connector 1 and the right connector 2 on the other hand.

[0030] Furthermore, such as Figure 1 and Figure 3 As shown, the left positioning component includes two half-plates 18. Multiple left screw holes 20 are evenly provided on the half-plates 18. A plate pad 19 is fixedly provided on the right side of the half-plates 18. The plate pad 19 fits against the ring plate 9. The corresponding left screw holes 20 and right screw holes 16 are connected by screws. Through this structure, the kit 14 is connected and positioned, thereby improving the stability and sealing of the connection between the left connector 1 and the right connector 2.

[0031] Furthermore, such as Figure 1 As shown, a hexagonal piece 21 is fixedly installed on the outer left side of the left connector 1. The hexagonal piece 21 is locked in place by a wrench. By rotating the hexagonal piece 21, the external thread 4 on the left side and the internal thread 5 on the right side are threaded together, thereby connecting the left connector 1 and the right connector 2.

[0032] Working principle: When the user installs the left connector 1 and the right connector 2;

[0033] By placing the left connector 1 and the right connector 2 opposite each other, the hexagonal piece 21 is rotated with a wrench, so that the left external thread 4 and the right internal thread 5 are threaded together. When the hexagonal piece 21 stops rotating, the annular groove 8 on the external clamp 7 and the annular frame 10 on the annular plate 9 are tightly engaged, and the sealing gasket 12 on the right end of the left connector 1 is tightly engaged with the inner support ring 11 on the inner side of the right connector 2, thereby improving the sealing performance and stability of the connection between the left connector 1 and the right connector 2.

[0034] By using the structure of the auxiliary installation mechanism, the stability and sealing of the connection between the left connector 1 and the right connector 2 are improved, and the operation is made easier for the user. By pre-fitting the kit 14 on the outside of the right connector 2, the kit 14 is moved to the left, so that the positioning ring 15 inside the right side of the kit 14 engages with the positioning groove 13 on the right side of the external card holder 7. At this time, the pad 17 on the inner wall of the kit 14 is in close contact with the side wall after the ring plate 9 and the external card holder 7 are connected. Then, by using the structure of the left positioning component, the two half-connecting plates 18 are placed on the outside of the left connector 1, and the plate pad 19 on the right side of the half-connecting plate 18 is in close contact with the ring plate 9. The corresponding left screw hole 20 and right screw hole 16 are connected by screws, thereby connecting and positioning the kit 14, thus improving the stability and sealing of the connection between the left connector 1 and the right connector 2.

[0035] The design of the pipe joint makes it easy for users to operate and use, thus enabling quick connection of the pipe joint.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
