[0017] Please see Figure 1-5 This utility model provides an easy-to-assemble automotive air conditioning heat exchange system connector, including a heat exchange main pipe 1, a hexagonal sleeve 2 fixedly connected to the side of the heat exchange main pipe 1, a threaded connector 3 connected to the side of the hexagonal sleeve 2, a secondary pipe 10 provided on the side of the heat exchange main pipe 1, a connecting pipe 4 fixedly connected to the bottom of the secondary pipe 10, an inner pipe 5 and an embedded pipe 6 respectively provided on the inner side of the connecting pipe 4, a positioning block 7 fixedly connected to the bottom side of the inner pipe 5, a locking element 9 movably connected to the top of the positioning block 7, and two positioning blocks 7, with ball bearings 8 embedded in the bottom of the two positioning blocks 7; the ball bearings 8 at the bottom of the positioning blocks 7 can prevent the positioning blocks 7 from getting stuck inside the heat exchange main pipe 1, thus preventing them from entering the positioning groove 15 for quick assembly.

[0018] In summary, the heat exchange main pipe 1 is connected to the secondary pipe 10 via the connecting pipe 4 and the inner pipe 5 at the top. The embedded pipe 6 on the side of the inner pipe 5 engages with the groove 13 on the inner side of the heat exchange main pipe 1, achieving a preliminary seal. Furthermore, the positioning block 7 on the bottom side of the inner pipe 5 cooperates with the sliding groove 14 and the positioning groove 15 on the inner side of the heat exchange main pipe 1, allowing for quick assembly and connection between the secondary pipe 10 and the main pipe. This avoids the problem of rusting of the internal threaded section after long-term use, which would make disassembly difficult. The positioning block 7 on the side of the inner pipe 5 is equipped with a locking element 9, and the locking plate 91 inside the locking element 9 is movably engaged within the positioning block 7. On the side, a spring 94 is fixedly connected to the inner side of the bottom groove 93 at the bottom of the locking plate 91. The spring 94 provides a restoring force to press the locking plate 91, which can firmly lock the positioning block 7 inside the positioning groove 15 inside the heat exchange main pipe 1. This can improve the sealing performance of the heat exchange main pipe 1 and the auxiliary pipe 10, and solve the problem that the sealing performance of the connection between the main pipe and the auxiliary pipe 10 of the existing automotive air conditioning heat exchange system decreases due to long-term use, and it needs to be replaced and maintained regularly. However, the main pipe and the auxiliary pipe 10 are generally connected by threads. After long-term use, the internal thread section rusts, which makes disassembly difficult.

[0019] The locking component 9 includes a locking plate 91, a limiting plate 92, a bottom groove 93, and a spring 94. The locking plate 91 is movably connected to the inside of the positioning block 7, and the limiting plate 92 is fixedly connected to the bottom side of the locking plate 91.

The top of the positioning block 7 on the side of the inner tube 5 is provided with the locking component 9. The locking plate 91 inside the locking component 9 is movably engaged with the inside of the positioning block 7. The bottom groove 93 of the locking plate 91 is fixedly connected to the inside of the spring 94. The spring 94 provides a restoring force to squeeze the locking plate 91, so that the positioning block 7 can be firmly locked inside the positioning groove 15 inside the heat exchange main pipe 1, which can improve the sealing performance of the heat exchange main pipe 1 and the secondary pipe 10.

[0020] The top of the main heat exchange pipe 1 is provided with a groove 13 and a slide 14. The inner sides of the groove 13 and the slide 14 are respectively connected to the inner tube 6 and the positioning block 7. The top of the main heat exchange pipe 1 is connected to the secondary pipe 10 through the connecting pipe 4 and the inner tube 5. The inner tube 6 on the side of the inner tube 5 is engaged with the groove 13 on the inner side of the main heat exchange pipe 1 to achieve a preliminary seal. The positioning block 7 on the bottom side of the inner tube 5 is engaged with the slide 14 and the positioning groove 15 on the inner side of the main heat exchange pipe 1 to enable quick assembly and connection between the secondary pipe 10 and the main pipe. This avoids the problem of rusting of the internal thread section after long-term use due to the use of threaded connection, which would make disassembly difficult. The top of the secondary pipe 10 is provided with a slot 12. The inner side of the slot 12 is engaged with a soft plug sleeve 11. There are three soft plug sleeves 11. The inner side of the rear part of the main heat exchange pipe 1 is provided with a positioning groove 15. The inner side of the positioning groove 15 is engaged with the side of the positioning block 7.

[0021] In practical use, firstly, the heat exchange system pipes are connected to the outside of the main heat exchange pipe 1 and the auxiliary pipe 10 respectively. The top of the main heat exchange pipe 1 is connected to the auxiliary pipe 10 through the connecting pipe 4 and the inner pipe 5. The embedded pipe 6 on the side of the inner pipe 5 is engaged with the groove 13 on the inside of the main heat exchange pipe 1, which can achieve a preliminary seal. The positioning block 7 on the bottom side of the inner pipe 5 cooperates with the sliding groove 14 and the positioning groove 15 on the inside of the main heat exchange pipe 1, which can enable the auxiliary pipe 10 to be quickly assembled and connected to the main pipe. This avoids the problem of the internal thread section rusting after long-term use due to the use of threaded connection, which would make it difficult to disassemble. The top of the positioning block 7 on the side of the inner pipe 5 is provided with a locking part 9. The locking plate 91 inside the locking part 9 is movably engaged with the inside of the positioning block 7. A spring 94 is fixedly connected to the bottom groove 93 at the bottom of the locking plate 91. The spring 94 provides a restoring force to squeeze the locking plate 91, which can make the positioning block 7 firmly locked inside the positioning groove 15 on the inside of the main heat exchange pipe 1, thereby improving the sealing performance of the main heat exchange pipe 1 and the auxiliary pipe 10.
