Description

Technical Field

[0001] This utility model relates to the field of pipe joint structures, specifically to an air conditioning pipe joint structure. Background Technology

[0002] Air conditioning pipe joint structure is a key component in air conditioning system used to connect refrigeration pipes. Its core function is to achieve safe and sealed connection of pipes and ensure efficient circulation of refrigerant in the system.

[0003] Traditional air conditioning pipe joints use simple threaded connections. The sealing performance of this simple threaded connection depends entirely on the machining accuracy of the threads and the fit clearance. If there are burrs, deformation, or dimensional deviations in the threads, the sealing surfaces may not fit properly, leading to refrigerant leakage. Furthermore, the vibrations generated by the compressor, fan, and other components during air conditioning operation are transmitted to the pipe joints. Prolonged vibration can cause the threads to loosen, increasing the gap between the sealing surfaces and ultimately leading to leakage.

[0004] Therefore, it is necessary to invent an air conditioning pipe joint structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioning pipe connector structure. One end of the connecting pipe is fitted over the other end of the air conditioning pipe body. After the connecting pipe enters the connector, it drives the external connecting sleeve and the limiting block to slide into the limiting groove inside the connector. During insertion, the connecting sleeve compresses the stop block and the rear spring. When the limiting block moves to the bottom of the limiting groove, the entire connecting pipe and connecting sleeve are rotated, causing the limiting block to slide within the limiting groove. After rotating to the bottom again, the connecting pipe is released, and the spring rebound pushes the stop block and the limiting block outside the connecting sleeve to move to the rear of the limiting groove for limitation. Then, the sleeve outside the connector is moved to connect threadedly to the fitting outside the connecting pipe, achieving a secure connection. This solves the problem of the traditional air conditioning pipe connector structure mentioned in the background art, which uses a simple threaded connection. The sealing performance of this simple threaded connection depends entirely on the machining accuracy and fit clearance of the thread. If there are burrs, deformation, or dimensional deviations in the thread, the sealing surface may not fit properly, causing refrigerant leakage. Furthermore, during air conditioning operation, the vibrations generated by components such as the compressor and fan are transmitted to the pipe connector. Prolonged vibration may cause threads to loosen, increase the gap between the sealing surfaces, and thus lead to leakage problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning pipe joint structure, comprising an air conditioning pipe body; A connector is fixed to the outside of the air conditioning pipe body. A spring is sleeved inside the connector and outside the air conditioning pipe body. A stop block is fixedly connected to the front end of the spring. Limit grooves are opened on the upper and lower sides inside the connector. Moving grooves are opened on the upper and lower sides of the connector. A sleeve is slidably connected to the outside of the connector. A connecting pipe is fitted onto the other end of the air conditioning pipe body. A kit is fixedly connected to the outside of the connecting pipe, and a connecting sleeve is fixedly connected to the inside of the kit. Limiting blocks are fixedly connected to the upper and lower sides of the connecting sleeve.

[0007] Preferably, the stop block is slidably connected to the inside of the connector, and a sealing element is embedded at the front end of the stop block.

[0008] Preferably, the limiting groove is a U-shaped groove, and the connecting sleeve is slidably connected to the limiting block and the limiting groove inside the connector.

[0009] Preferably, the upper and lower sides of the sleeve are fixedly connected to movable blocks, and the movable blocks are located in the movable groove outside the joint.

[0010] Preferably, the sleeve has an internal thread on its front side and the kit has an external thread on its exterior, and the sleeve and the kit are threadedly connected.

[0011] Preferably, the outer dimensions of the connecting sleeve match the inner wall dimensions of the connector, and the front end of the connecting sleeve abuts against the stop block.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention enhances the overall connectivity and robustness through the design of a connector, spring, stop, moving groove, sleeve, connecting pipe, kit, connecting sleeve, and limiting block. One end of the connecting pipe is fitted over the other end of the air conditioning pipe body. After the connecting pipe enters the connector, it causes the outer connecting sleeve and limiting block to slide into the limiting groove inside the connector. During insertion, the connecting sleeve compresses the stop and the rear spring. When the limiting block moves to the bottom within the limiting groove, the entire connecting pipe and connecting sleeve are rotated, causing the limiting block to slide within the limiting groove. After rotating to the bottom again, the connecting pipe is released, and the spring rebound pushes the stop and the limiting block outside the connecting sleeve to move to the rear of the limiting groove for a more secure connection. Finally, the sleeve outside the connector is moved to connect threadedly to the kit outside the connecting pipe, achieving a robust connection. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-6 The air conditioning pipe joint structure shown includes an air conditioning pipe body 1; The connector 2 is fixed to the outside of the air conditioning pipe body 1. A spring 3 is sleeved inside the connector 2 and outside the air conditioning pipe body 1. A stop block 4 is fixedly connected to the front end of the spring 3. Limit grooves 6 are opened on the upper and lower sides inside the connector 2. Moving grooves 7 are opened on the upper and lower sides of the connector 2. A sleeve 8 is slidably connected to the outside of the connector 2. A connecting pipe 11 is fitted onto the other end of the air conditioning pipe body 1. A fitting 12 is fixedly connected to the outside of the connecting pipe 11, and a connecting sleeve 14 is fixedly connected to the inside of the fitting 12. Limiting blocks 15 are fixedly connected to the upper and lower sides of the connecting sleeve 14. By fitting one end of the connecting pipe 11 onto the outside of the other end of the air conditioning pipe body 1, and then inserting the connecting pipe 11 into the connector 2, the external connecting sleeve 14 and the limiting blocks 15 slide into the limiting groove 6 inside the connector 2. During the insertion process, the connecting sleeve 14 will squeeze... Press the stop block 4 and the rear spring 3. When the limiting block 15 moves to the bottom in the limiting groove 6, rotate the entire connecting pipe 11 and the connecting sleeve 14 so that the limiting block 15 slides in the limiting groove 6. When it rotates to the bottom again, release the connecting pipe 11. Use the spring 3 to push the stop block 4 and the limiting block 15 outside the connecting sleeve 14 to move to the rear of the limiting groove 6 for limitation. Then move the sleeve 8 outside the connector 2 to the fitting 12 outside the connecting pipe 11 for threaded connection, so as to achieve a firm connection.

[0018] like Figure 2 and Figure 3 As shown, the stop block 4 is slidably connected to the connector 2. The front end of the stop block 4 is inlaid with a sealing element 5. The stop block 4 is pushed by the spring 3 on the rear side, which can squeeze the connecting sleeve 14 and the connecting pipe 11 to strengthen the connection. At the same time, the stop block 4 inlaid at the front end of the stop block 4 strengthens the sealing between them.

[0019] like Figure 2 , Figure 4 and Figure 5 As shown, the limiting groove 6 is a U-shaped groove. The connecting sleeve 14 is slidably connected to the limiting block 15 and the limiting groove 6 inside the connector 2. The limiting block 15 on both sides of the connecting sleeve 14 slides into the limiting groove 6. Since the limiting groove 6 is a U-shaped groove, it can rotate 90° after sliding to the bottom. Then, when the connecting sleeve 14 is released, the spring 3 on the back side of the stop 4 pushes the limiting block 15 to move backward in the limiting groove 6, thereby strengthening the connection.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, movable blocks 9 are fixedly connected to the upper and lower sides of the inner side of the sleeve 8, and the movable blocks 9 are located in the movable groove 7 outside the connector 2. The sleeve 8 can extend and retract in the movable groove 7 outside the connector 2 through the movable blocks 9. After moving to the bottom of the movable groove 7, it becomes a circular groove, which can drive the sleeve 8 to rotate.

[0021] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the sleeve 8 has an internal thread 10 on its front side and the kit 12 has an external thread 13 on its outside. The sleeve 8 and the kit 12 are threadedly connected. When the sleeve 8 moves inside the connector 2, and the sleeve 8 contacts the outside of the kit 12, the sleeve 8 is rotated to connect to the kit 12, thereby strengthening the firmness between the air conditioning pipe body 1 and the connecting pipe 11.

[0022] like Figure 3 and Figure 6 As shown, the external dimensions of the connecting sleeve 14 match the inner wall dimensions of the connector 2. The front end of the connecting sleeve 14 abuts against the stop 4. When the connecting sleeve 14 moves within the connector 2, the abutting stop 4 and the sealing element 5 not only achieve a sealing effect, but also strengthen the connection between them.

[0023] The working principle of this practical device is as follows: First, one end of the connecting pipe 11 is fitted onto the outside of the other end of the air conditioning pipe body 1. After the connecting pipe 11 enters the connector 2, it drives the external connecting sleeve 14 and the limiting block 15 to slide into the limiting groove 6 inside the connector 2. During the insertion process, the connecting sleeve 14 will abut against and squeeze the stop block 4 and the spring 3 on the rear side. After the limiting block 15 moves to the bottom in the limiting groove 6, the entire connecting pipe 11 and the connecting sleeve 14 are rotated, so that the limiting block 15 slides to 90° in the limiting groove 6. When it rotates to the bottom again, the connecting pipe 11 is released. The spring 3 rebounds and pushes the stop block 4 and the connecting sleeve 14 and the external limiting block 15 to move to the rear side of the limiting groove 6 for limitation. Then, the sleeve 8 on the outside of the connector 2 is moved so that the sleeve 8 is fitted onto the fitting 12 on the outside of the connecting pipe 11 and rotated and tightened to make the two threadedly connected, strengthening the overall connection. In this way, the use process of this air conditioning pipe connector structure is completed.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
