Description

Technical Field

[0001] This patent relates to the technical field of connectors, and specifically to an automotive air-conditioning pipe connector. Background Art

[0002] The internal air conditioner of an automobile has multiple sections of pipelines, and the connection between pipelines is assembled and connected through connectors. Most of the existing connectors are composed of a threaded cover and a sealing ring. The threaded cover is screwed onto the end of another pipe fitting, and then the sealing ring is sealed at the end of the pipe fitting. However, the sealing ring will rotate with the threaded cover and press against the end of the pipe fitting. The rotational contact easily causes the sealing ring to wrinkle, resulting in reduced sealing performance, and it is also easy to cause severe wear of the sealing ring. For this reason, we propose an automotive air-conditioning pipe connector. Summary of the Utility Model

[0003] The purpose of this patent is to provide an automotive air-conditioning pipe connector to solve the problems raised in the above background art.

[0004] To achieve the above purpose, this patent provides the following technical solution: An automotive air-conditioning pipe connector includes a first pipe fitting and a second pipe fitting.

Limit sliding grooves are provided at both the upper and lower ends on the right side surface of the external thread ring. The left end of the limit sliding rod is inserted into the limit sliding groove, and the side wall of the limit sliding rod is in relative sliding contact with the inner side wall of the limit sliding groove.

[0007] Preferably, the left end of the limit sliding rod extends beyond the left end surface of the internal thread ring.

[0008] Preferably, the rotating ring includes a circular ring. The outer side wall of the circular ring is fixedly installed on the inner side wall of the connecting ring. Roller seats are connected to both the upper and lower ends and the left and right sides of the inner side wall of the circular ring, and rollers are installed on the roller seats and roll in the circular ring groove.

[0009] Preferably, the circular ring includes a first semi-circular ring and a second semi-circular ring, and the two ends of the first semi-circular ring and the second semi-circular ring are opposite to each other.

[0010] Preferably, threaded grooves are provided at the top of the outer side wall of the first semi-circular ring and the bottom of the outer side wall of the second semi-circular ring.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of this patent in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this patent without creative efforts shall fall within the scope of protection of this patent.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 This patent provides a technical solution: an automotive air-conditioning pipe connector, which includes a first pipe fitting 1 and a second pipe fitting 4. A circular groove is provided on the right side of the first pipe fitting 1, and a sealing ring 2 is fixedly installed in the circular groove. An external thread ring 3 is integrally formed on the outer side wall of the first pipe fitting 1. A pressing ring 5 is integrally formed on the left side of the second pipe fitting 4. The diameter of the pressing ring 5 matches the diameter of the sealing ring 2. A fixing ring 6 is integrally formed on the outer side wall of the second pipe fitting 4. A circular ring groove 7 is provided on the outer side wall of the fixing ring 6. A rotating ring 8 is rotatably installed in the circular ring groove 7. A connecting ring 9 is fixedly installed on the outer side wall of the rotating ring 8. An internal thread ring 10 is fixedly installed at the left end of the connecting ring 9. The inner side wall of the internal thread ring 10 is screwed onto the outer side wall of the external thread ring 3;

[0020] The rotating ring 8 can rotate in the circular ring groove 7, so that the connecting ring 9 and the internal thread ring 10 can rotate relative to the fixing ring 6.

[0021] Limiters are provided at both the upper and lower ends on the left side of the fixing ring 6.

[0022] The limiters are used to limit the movement trajectories of the fixing ring 6 and the second pipe fitting 4, so that they can only move left and right.

[0023] Specifically, the limiter includes a limit slide bar 11. The right end of the limit slide bar 11 is integrally formed on the left side surface of the fixing ring 6. Limit slide grooves 12 are provided at both the upper and lower ends on the right side surface of the external thread ring 3. The left end of the limit slide bar 11 is inserted into the limit slide grooves 12, and the side wall of the limit slide bar 11 is in relative sliding fit with the inner side wall of the limit slide grooves 12.

[0024] Specifically, the left end of the limit slide bar 11 extends beyond the left end surface of the internal thread ring 10.

[0025] By the left end of the limit slide bar 11 extending beyond the left end surface of the internal thread ring 10, when the internal thread ring 10 is not screwed onto the external thread ring 3, the limit slide bar 11 can be inserted into the limit slide grooves 12 first to play a limiting role.

[0026] Specifically, the swivel ring 8 includes a circular ring 13, the outer side wall of the circular ring 13 is fixedly installed on the inner side wall of the connecting ring 9, and roller seats are connected to rollers 14 at both upper and lower ends and both left and right sides of the inner side wall of the circular ring 13, and the rollers 14 are rotatably installed in the circular ring groove 7.

[0027] If a ring body directly slides in the circular ring groove 7, it is a sliding friction at this time, and the frictional force is large, which is not convenient for rotating the internal thread ring 10. As Figure 1 shown, the rollers 14 on both sides are used to roll on the left and right side walls inside the circular ring groove 7, and the rollers 14 on the inner side wall of the circular ring 13 are used to roll on the inner side wall of the circular ring groove 7, which can change the sliding into rolling, reduce the friction, and facilitate the rotation of the internal thread ring 10.

[0028] Specifically, the circular ring 13 includes a first semi-circular ring 15 and a second semi-circular ring 16, and the two ends of the first semi-circular ring 15 and the second semi-circular ring 16 are opposite to each other.

[0029] By dividing the circular ring 13 into the first semi-circular ring 15 and the second semi-circular ring 16, it is convenient to install the circular ring 13 in the circular ring groove 7 in the early stage.

[0030] Specifically, threaded grooves 17 are provided at the top of the outer side wall of the first semi-circular ring 15 and the bottom of the outer side wall of the second semi-circular ring 16, mounting holes 18 are provided at both upper and lower ends of the side wall of the connecting ring 9, bolts 19 are provided in the mounting holes 18, and the ends of the bolts 19 pass through the mounting holes 18 and are screwed into the threaded grooves 17.

[0031] Specifically, the bolt 19 includes a round plate 20 and a fitting ring 22. A screw rod 21 is integrally formed in the middle of one side surface of the round plate 20, the fitting ring 22 is sleeved on the screw rod 21, and an arc-shaped groove 23 is provided on one side surface of the fitting ring 22.

[0032] The inner arc surface of the arc-shaped groove 23 matches the outer arc surface of the outer side wall of the connecting ring 9. After tightening the screw rod 21, the arc-shaped groove 23 can be completely pressed against the outer side wall of the connecting ring 9, increasing the fitting and pressing degree.

[0033] Working principle: By rotating the internal thread ring 10 and screwing it onto the external thread ring 3 and moving it to the left, the limit slide rod 11 is inserted into the limit slide groove 12, which is used to limit the movement trajectories of the fixed ring 6 and the second pipe fitting 4, so that the second pipe fitting 4 moves to the left, and then the pressing ring 5 moves linearly to the left and presses tightly on the sealing ring 2, ensuring the sealing effect of the sealing ring 2 and preventing air leakage in the air-conditioning pipeline.
