DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the embodiments:

[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 10As shown, an air conditioning heat exchange pipe valve group includes a solenoid valve 1 and a one-way valve 2, the solenoid valve 1 and the one-way valve 2 are connected by a first connecting pipe 3, one end of the one-way valve 2 is connected to a heat exchange elbow 4, and the other end of the solenoid valve 1 is connected to a second connecting pipe 5 with an annular buffer portion 51, and a quick connection component 6 is provided between the one-way valve 2 and the first connecting pipe 3 and between the one-way valve 2 and the heat exchange elbow 4. The quick connection component 6 includes a connector 61 provided at the end of the one-way valve 2, and a mounting seat 62 is clamped in the connector 61. The heat exchange elbow 4 and the second connecting pipe 5 are both provided with A bending portion 71 is provided, and a first positioning groove 72 is formed between the bending portion 71 and the outer wall of the heat exchange elbow 4 and the outer wall of the second connecting pipe 5. The heat exchange elbow 4 and the second connecting pipe 5 are detachably connected to a positioning block 63 that can be inserted into the first positioning groove 72. The quick connection assembly 6 also includes a locking piece 64 that can be sleeved on the outside of the positioning block 63. The locking piece 64 is detachably connected to the connecting head 61, and when the locking piece 64 is installed on the connecting head 61, the locking piece 64 presses the positioning block 63 so that the bending portion 71 is clamped and fixed by the positioning block 63 and the mounting seat 62.

[0031] When it is necessary to install and connect the various pipes, first, the positioning block 63 is sleeved on the heat exchange elbow 4 and the second connecting pipe 5 and snapped into the first positioning groove 72, then the mounting seat 62 is snapped into the connecting head 61, and the locking piece 64 is sleeved on the outside of the positioning block 63, and then the heat exchange elbow 4 or the second connecting pipe 5 is moved so that the bending portion 71 moves toward the mounting seat 62, and then it is quickly connected to the connecting head 61 through the locking piece 64. When the locking piece 64 is locked with the connecting head 61, the positioning block 63 cooperates with the mounting seat 62 to clamp the bending portion 71, thereby quickly connecting the one-way valve 2 to the second connecting pipe 5 or the heat exchange elbow 4, making the connection more stable. At the same time, it can also be quickly adjusted when an error occurs in the installation of the one-way valve 2, making it more convenient to install and use.

[0032] The mounting seat 62 is provided with an annular wall 621 extending upward and covering the outer side of the bent portion 71. A plurality of convex slots 622 are provided around the outer periphery of the annular wall 621. The slots 622 are provided with a clamping block 65 that can be clamped in. The clamping block 65 is provided with a plurality of clamping teeth 651 on the side adjacent to the bent portion 71. The plurality of clamping blocks 65 cooperate with each other, and the plurality of clamping teeth 651 thereon clamp the bent portion 71, thereby securing it more firmly.

[0033] The block 65 is provided with an inclined surface 652 that can be pushed by the inner wall of the locking member 64. The arrangement of the inclined surface 652 enables the clamping teeth 651 on each block 65 to clamp each other more compactly and the clamping fixation to be more stable.

[0034] The connector 61 is provided with a first protrusion 611 extending outward, with a first curved surface A formed on the inner side of the first protrusion 611. The outer side wall of the mounting seat 62 is provided with a second curved surface B that extends inward at an angle and abuts against the first curved surface A. The end portion of the inner side wall C of the locking member 64 can abut against the outer side wall D of the mounting seat 62 and the outer side wall E of the first protrusion 611. The first curved surface A and the second curved surface B cooperate to position and install the connector 61 and the mounting seat 62, allowing for smoother sliding during installation. At the same time, the end portion of the inner side wall C of the locking member 64 can abut against the outer side wall D of the mounting seat 62 and the outer side wall E of the first protrusion 611, providing a more stable and secure installation.

[0035] The positioning block 63 is provided with a second positioning groove 631, and the locking member 64 is provided with a protrusion 641 that protrudes outward into the second positioning groove 631 and presses against the positioning block 63. The arrangement of the protrusion 641 allows the locking member 64 to have sufficient pressure to press against the second positioning groove 631 and tighten the positioning block 63.

[0036] The connector 61 is provided with a step 612 for the mounting seat 62 to abut against, a top surface 6121 of the step 612 is provided with a groove 6122, and the mounting seat 62 is provided with a raised ring 623 that can be snapped into the groove 6122. The step 612 can abut against the mounting seat 62 for support, and the provision of the raised ring 623 also facilitates mutual snapping and positioning with the groove 6122.

[0037] The positioning block 63 is composed of two identically structured bases 632. The bases 632 are provided with a semicircular groove 6321 that mates with the outer walls of the heat exchange elbow 4 and the second connecting pipe 5. The front end of the base 632 is provided with a positioning portion 6322 that extends into the first positioning groove 72. The mounting base 62 is configured with two bases 632, which can accommodate pipes with structures such as elbows, providing a wider range of adaptability and facilitating installation. The positioning portion 6322 easily snaps into the first positioning groove 72, facilitating faster positioning.

[0038] An annular notch 624 is provided on the outer side of the mounting seat 62 to facilitate processing and reduce material.

[0039] The connector 61 is provided with a limiting groove 613, and the locking member 64 is further provided with a limiting block 642 that abuts against the bottom side of the limiting groove 613 to prevent further rotation of the locking member 64. The limiting groove 613 is designed to accommodate the limiting block 642. When the limiting block 642 abuts against the bottom side of the limiting groove 613, the locking member 64 cannot rotate further downward and reaches a predetermined limit position.

[0040] The locking member 64 is threadedly connected to the connector 61. The locking member 64 and the connector 61 are conveniently and quickly connected, so that the one-way valve 2 can be quickly connected to various pipelines.

[0041] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
