Description

Technical Field

[0001] The utility model relates to the technical field of valve seat joints, in particular to the technical field of valve seat joints for automobile air conditioners. Background Art

[0002] Car air conditioning devices, also known as car air conditioners, are used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue.

[0003] When installing an automobile air conditioner, a safety valve seat joint is required to connect the automobile air conditioner. However, there are still some problems with the existing valve seat joint during installation and connection. The existing method generally involves sleeves on the valve seat joint, and then the pipe and the valve seat joint are connected and fixed by an outer hoop. Due to the lack of a sealing gasket, leakage may occur, resulting in loose connections and unstable connections. After long-term use, the pipe and the valve seat joint may break, which is inconvenient for long-term use.

[0004] In order to solve the problems raised in the background technology, for example, application number CN202222022989.9 discloses a safe and stable valve seat joint for automobile air conditioning, including a main pipe, one end of the main pipe is fixedly connected to a fixed plate, and the fixed plate is located at the end away from the main pipe and is provided with a rotatable splint, and the splint is provided with a detachable connecting pipe through the internal thread of the inner wall, and the circumferential surface of the connecting pipe in contact with the internal thread of the splint is provided with an external thread that meshes with the internal thread of the splint, and through the setting of the internal thread of the inner wall of the fixed pipe and the external thread of the circumferential surface of the connecting pipe, the fixed pipe can be sleeved on the connecting pipe by rotating the main pipe, and then the splint is rotated, and the splint will be connected to the connecting pipe through the thread of the inner wall, and when the splint is When rotating, the connecting pipe will be driven to slide toward the inner side of the splint. After the connecting pipe is fully fitted with the first sealing gasket, the splint can be stopped to fix the main pipe. Then, the rotating pipe will be rotated, and the rotating pipe will drive the positioning piece. Through the external thread provided on the surface of the positioning piece, the positioning piece can be rotated to install and fix the positioning piece. When the rotating pipe is rotated, the sleeve will be fitted with the limit block to rotate, and the limit block will rotate in the branch pipe. When the bottom of the limit block is fitted with the inner wall of the branch pipe, due to the setting of the second sealing gasket, the sleeve will be tightly fitted with the branch pipe, thereby completing the stable fixed installation of the positioning piece, and realizing a stable connection of the entire device. However, this structure still has the following defects:

[0005] Although this structure improves the sealing effect by providing a first sealing gasket and a second sealing gasket, the structure adopts a threaded installation method, which makes it easy for threads to slip during the process of connecting the pipes. The threaded connection is also prone to damage, causing the medium inside the pipe to leak and cause waste, thereby leading to the problem of poor sealing and stability of the connection between the two pipes. Summary of the Invention

[0006] The purpose of the utility model is to solve the problems in the prior art and to propose a valve seat joint for automobile air conditioners, which can improve the sealing of the pipeline while ensuring the stability during connection, is less likely to cause thread misalignment and slippage, and extends the service life of the pipeline.
