Description

Technical Field

[0001] This application relates to the field of refrigerant pipe connector technology, specifically a snap-on air conditioning refrigerant pipe connector. Background Technology

[0002] In air conditioning systems, refrigerant pipe connectors are key components for refrigerant circulation, and their performance directly affects the system's sealing, energy efficiency, and reliability. Traditional connection methods mainly include welding, threaded connections, quick-connect fittings, and flange connections.

[0003] However, most existing refrigerant pipe connectors are threaded connections. After long-term vibration or thermal expansion and contraction, the tightening force at the threaded connection may gradually weaken, creating tiny gaps. Under high pressure, the refrigerant can easily leak through these gaps, which not only reduces refrigeration efficiency but may also cause danger. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a snap-fit ​​type air conditioning refrigerant pipe connector, which has advantages such as enhanced sealing performance. It solves the problem that most existing refrigerant pipe connectors are threaded connections. After long-term vibration or thermal expansion and contraction, the tightening force at the threaded connection may gradually weaken, creating tiny gaps. Under high pressure, refrigerant can easily leak through these gaps, which not only reduces cooling efficiency but may also cause dangerous problems.

[0005] To achieve the above objectives, this application provides the following technical solution: a snap-fit ​​air conditioning refrigerant pipe connector, comprising a first connector, a second connector, and a movable ring. The first connector has four first sliding grooves arranged in a circular array on one side of its inner wall, and each of the four first sliding grooves has a retaining groove at one end. The first connector has an external thread on one side of its outer wall. The second connector has four second sliding grooves arranged in a circular array on its outer wall. The movable ring has four sliders arranged in a circular array fixedly connected to its inner wall. A rotating ring is rotatably disposed inside the movable ring. A locking sleeve is fixedly connected to the outer wall of the rotating ring, and the locking sleeve has an internal thread on its inner wall.

[0006] Through the above scheme, the cooperation of the first groove, the slot, and the snap fastener, combined with the threaded connection between the internal thread of the locking sleeve and the external thread of the first connector, a dual fixing mechanism is achieved. This design not only ensures the stability of the connection but also simplifies the installation process. The snap-fit ​​structure allows the second connector to be quickly inserted into the first connector and initially positioned, and then the final locking is completed by rotating the locking sleeve, shortening the installation time. During installation, the user only needs to insert the second connector into the first connector, screw the snap fastener into the slot, and then rotate the locking sleeve to complete the connection. No complicated tools or operating steps are required. When disassembly or maintenance is required, the connector can be easily separated by simply rotating the locking sleeve in the opposite direction. The snap-fit ​​connection method can resist the effects of vibration and thermal expansion and contraction, reducing the risk of connection loosening caused by vibration or temperature changes and enhancing its sealing performance. This snap-fit ​​air conditioning refrigerant pipe connector has the advantages of efficient connection, excellent sealing performance, stable structure, and convenient maintenance, improving the installation efficiency, operational stability, and maintenance convenience of the air conditioning system.

[0007] Furthermore, four second sealing rings arranged in a linear array are fixedly connected to one side of the outer wall of the second connector, and a first sealing ring is fixedly connected to one end of the locking sleeve.

[0008] Through the above scheme, the first sealing ring at one end of the locking sleeve forms the first sealing barrier during the locking process, preventing refrigerant from leaking from the outer wall of the connector. The four second sealing rings on the outer wall of the second connector are distributed in a linear array, forming multiple sealing contacts with the inner wall of the first connector, further preventing refrigerant from leaking from the inside of the connector. The first sealing ring and the second sealing ring work together to form a double sealing structure, reducing the risk of leakage.

[0009] Furthermore, a retaining ring is fixedly connected to the outer wall of the second connector, and a third sealing ring is fixedly connected to one end of the retaining ring.

[0010] With the above solution, the third sealing ring contacts the end face of the first connector, further improving the sealing effect. The retaining ring, as a limiting component, is used to limit the position of the first connector.

[0011] Furthermore, a first rotating block is fixedly connected to the outer wall of the first connector, and a second rotating block is fixedly connected to the outer wall of the locking sleeve.

[0012] With the above scheme, the first and second rotating blocks, as external protruding structures, provide a larger gripping area and friction, and also allow the use of open-end wrenches and other tools for auxiliary tightening.

[0013] Furthermore, a connecting pipe is fixedly connected to one end of the first connector.

[0014] With the above solution, the connecting pipe, as an extension of the first connector, can be directly connected to the refrigerant pipe in the air conditioning system.

[0015] Furthermore, all four sliders are slidably disposed inside the second groove.

[0016] With the above scheme, the four sliders are symmetrically distributed in the second slide groove to form a stable four-way support structure, and the locking sleeve can slide on the outer wall of the second connector through the sliding setting.

[0017] Furthermore, one end of the second connector is slidably disposed inside the first connector, and the four second grooves are slidably disposed inside the slot.

[0018] With the above scheme, four second sliding grooves are slidably set inside the slot to form a four-way snap-fit ​​structure. When the second connector rotates, the cooperation between the sliding groove and the slot makes the connector firmly locked in the radial direction, avoiding loosening of the connection due to vibration or external force.

[0019] Furthermore, the locking sleeve is rotatably disposed outside the second connector, and the external thread and the internal thread are threadedly connected.

[0020] With the above solution, the external thread is set on the first connector and the internal thread is set inside the locking sleeve. By screwing the threads together, the locking sleeve further presses the second connector and the first connector together, forming a double fixation in the axial and radial directions. The threaded connection has a self-locking characteristic and can only be unlocked by rotating the locking sleeve, thus avoiding accidental separation due to misoperation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This snap-fit ​​air conditioning refrigerant pipe connector utilizes a first sliding groove, a locking groove, and a snap fastener. The internal thread of the locking sleeve connects to the external thread of the first connector, achieving a dual-fixing mechanism. This design ensures connection stability while simplifying installation. The snap-fit ​​structure allows the second connector to be quickly inserted into the first connector for initial positioning, followed by final locking by rotating the locking sleeve, shortening installation time. During installation, users simply insert the second connector into the first connector, screw the snap fastener into the locking groove, and then rotate the locking sleeve to complete the connection. No complex tools or procedures are required. For disassembly or maintenance, simply rotate the locking sleeve in the opposite direction to easily separate the connector. The snap-fit ​​connection resists vibration and thermal expansion and contraction, reducing the risk of loosening due to vibration or temperature changes and enhancing sealing. This snap-fit ​​air conditioning refrigerant pipe connector offers advantages such as efficient connection, excellent sealing performance, a stable structure, and convenient maintenance, improving the installation efficiency, operational stability, and maintenance convenience of air conditioning systems.

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

[0025] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a snap-fit ​​air conditioning refrigerant pipe connector includes a first connector 1, a second connector 2, and a moving ring 8. The inner wall of the first connector 1 has four first sliding grooves 3 arranged in a circular array on one side. Each of the four first sliding grooves 3 has a slot 4 at one end. The second connector 2 is inserted into the first connector 1, and the snap-fit ​​is screwed into the slot 4. The outer wall of the first connector 1 has an external thread 5. The outer wall of the second connector 2 has four second sliding grooves 6 arranged in a circular array, providing a sliding track for the moving ring 8. Four sliders 7 arranged in a circular array are fixedly connected to the inner wall of the moving ring 8. A rotating ring 9 is rotatably disposed inside the moving ring 8. A locking sleeve 10 is fixedly connected to the outer wall of the rotating ring 9. The inner wall of the locking sleeve 10 has an internal thread 11. Through the cooperation of the first sliding grooves 3, slots 4, and snap-fit, combined with the threaded connection between the internal thread 11 of the locking sleeve 10 and the external thread 5 of the first connector 1, a dual fixing mechanism is achieved.

[0026] Please see Figure 1 , Figure 3 and Figure 5 Four second sealing rings 13 arranged in a linear array are fixedly connected to one side of the outer wall of the second connector 2. A first sealing ring 12 is fixedly connected to one end of the locking sleeve 10. The first sealing ring 12 at one end of the locking sleeve 10 forms a first sealing barrier during the locking process to prevent refrigerant from leaking from the outer wall of the connector. The four second sealing rings 13 on the outer wall of the second connector 2 are arranged in a linear array and form multiple sealing contacts with the inner wall of the first connector 1, further preventing refrigerant from leaking from the inside of the connector. The first sealing ring 12 and the second sealing ring 13 work together to form a double sealing structure, reducing the risk of leakage. A retaining ring 14 is fixedly connected to the outer wall of the second connector 2. One end of the retaining ring 14 is fixed... A third sealing ring 15 is connected, which contacts the end face of the first connector 1 to further improve the sealing effect. The retaining ring 14 serves as a limiting component to restrict the position of the first connector 1. A first rotating block 16 is fixedly connected to the outer wall of the first connector 1, and a second rotating block 17 is fixedly connected to the outer wall of the locking sleeve 10. The first rotating block 16 and the second rotating block 17 serve as external protruding structures, providing a larger gripping area and friction, and also allowing the use of open-end wrenches and other tools for auxiliary tightening. A connecting pipe 18 is fixedly connected to one end of the first connector 1. The connecting pipe 18 serves as an extension of the first connector 1 and can be directly connected to the refrigerant pipe in the air conditioning system.

[0027] Please see Figure 3 , Figure 4 and Figure 5 Four sliders 7 are slidably disposed inside the second slide groove 6, forming a stable four-way support structure. Through the sliding arrangement, the locking sleeve 10 can slide on the outer wall of the second connector 2. One end of the second connector 2 is slidably disposed inside the first connector 1. The four second slide grooves 6 are slidably disposed inside the slot 4, forming a four-way snap-fit ​​structure. When the second connector 2 rotates, the cooperation between the first slide groove 3 and the slot 4 makes the connector firmly locked in the radial direction, avoiding loosening of the connection due to vibration or external force. The locking sleeve 10 is rotatably disposed outside the second connector 2, with a threaded connection between the external thread 5 and the internal thread 11. The external thread 5 is disposed on the first connector 1, and the internal thread 11 is disposed inside the locking sleeve 10. Through the thread engagement, the locking sleeve 10 further presses the second connector 2 and the first connector 1 together, forming a double fixation in the axial and radial directions. The threaded connection has a self-locking characteristic, and the locking sleeve 10 can only be unlocked by rotating it, avoiding accidental separation due to misoperation.

[0028] In this embodiment, the snap-fit ​​air conditioning refrigerant pipe connector achieves a dual fixing mechanism through the cooperation of the first sliding groove 3, the slot 4, and the snap-fit, combined with the threaded connection between the internal thread 11 of the locking sleeve 10 and the external thread 5 of the first connector 1. This design ensures the stability of the connection and simplifies the installation process. The snap-fit ​​structure allows the second connector 2 to be quickly inserted into the first connector 1 and initially positioned, followed by final locking by rotating the locking sleeve 10, shortening the installation time. During installation, the user only needs to insert the second connector 2 into the first connector 1 and rotate the snap-fit... Insert the connector into the slot 4 and then rotate the locking sleeve 10 to complete the connection. No complicated tools or operating steps are required. When disassembly or maintenance is needed, simply rotate the locking sleeve 10 in the opposite direction to easily separate the connector. The snap-fit ​​connection method can resist the effects of vibration and thermal expansion and contraction, reducing the risk of loosening due to vibration or temperature changes and enhancing its sealing performance. This snap-fit ​​air conditioning refrigerant pipe connector has the advantages of efficient connection, excellent sealing performance, stable structure and convenient maintenance, improving the installation efficiency, operational stability and maintenance convenience of the air conditioning system.

[0029] It should be noted that both the first rotating block 16 and the second rotating block 17 are hexagonal in shape, which can be used with tools such as open-end wrenches.

[0030] The working principle of the above embodiments is as follows: During installation, the second connector 2 is inserted into the first connector 1. The four clips slide along the first groove 3 until they are initially positioned inside the groove 4, forming the first mechanical lock. Then, the moving ring 8 slides axially along the second groove 6 via the slider 7, driving the rotating ring 9 and the locking sleeve 10 forward, so that the internal thread 11 of the locking sleeve 10 engages with the external thread 5 of the first connector 1. The threads are tightened by rotating the second rotating block 17, forming the second lock. During this process, the first sealing ring 12 at the end of the locking sleeve 10 is pressed and sealed with one end of the first rotating block 16. At the same time, the four second sealing rings 13 on the second connector 2 form multiple circumferential seals with the inner wall of the first connector 1. The third sealing ring 15 at the end of the retaining ring 14 further provides end face sealing, forming a triple anti-leakage barrier. When disassembling, the locking sleeve 10 can be rotated in the opposite direction to release the threaded connection and easily separate the connector. The locking of the groove 4 and the groove is limited by the threaded clamping to resist the influence of vibration. The hexagonal rotating block design allows for tool-assisted locking to ensure the installation torque.
