Description

Technical Field

[0001] This application belongs to the field of automotive piping, and in particular relates to an automotive air conditioning system piping assembly. Background Technology

[0002] The automotive air conditioning system piping assembly is one of the important components of the automotive air conditioning system. The injection-molded pressure plates at both ends of the piping assembly are designed to match the dimensions of the vehicle's evaporator, compressor, and condenser, and can be used to connect the evaporator and compressor or the compressor and condenser.

[0003] The existing publication number CN218972116U discloses an automotive air conditioning system piping assembly, including a hose, a connecting assembly, a first nylon tube, and a second nylon tube. The connecting assembly includes a first crimping collar, a second crimping collar, and a metal adapter.

[0004] Although the above-mentioned piping assembly can alleviate vibration and reduce vibration transmission through the hoses after the compressor starts, its positional stability is poor after installation. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing an automotive air conditioning system piping assembly that improves the positional stability of the piping assembly after installation.

[0006] This application provides an automotive air conditioning system piping assembly, including a first connecting pipe, a second connecting pipe, a welding pressure plate, and further comprising:

[0007] A connector body, which is installed between a first connecting pipe and a second connecting pipe;

[0008] The connector body is provided with two interconnected conveying pipes, and a sealing block is installed on the outside of the conveying pipe. The sealing block is used to insert into and abut against the inner wall of the opening of the first connecting pipe and the second connecting pipe.

[0009] When connecting the first and second connecting pipes, the first and second connecting pipes are respectively installed on the conveying pipes at both ends of the connector body. A sealing block is installed on the outside of the conveying pipe. The outer diameter of the sealing ring is larger than the inner wall diameter of the opening of the first and second connecting pipes. When the first and second connecting pipes are sleeved on the conveying pipes, the sealing block is inserted into the first or second connecting pipe and abuts against the inner wall of the first or second connecting pipe, so as to achieve the sealing and stability of the pipe body when the connector body is connected to the first or second connecting pipe.

[0010] Furthermore, the outer diameter of the sealing block is larger than the outer diameter of the openings of the first connecting pipe and the second connecting pipe, and the sealing block is in the shape of a circular boss.

[0011] The sealing block is in the shape of a circular boss, and the outer diameter of the side of the sealing block near the opening of the delivery pipe is smaller, making it easier and more efficient for the user to insert the sealing block into the first or second connecting pipe when fitting the first or second connecting pipe onto the delivery pipe.

[0012] Furthermore, a plurality of clamping collars are provided, the clamping collars are connected to and abut against the first connecting pipe and the second connecting pipe, and a plurality of concave annular grooves are provided on the inner wall of the clamping collars.

[0013] When the first connecting pipe and the second connecting pipe are inserted into the connector body, the annular groove on the clamping collar presses against the first connecting pipe or the second connecting pipe, and simultaneously squeezes the conveying pipe. At this time, the positions of the first connecting pipe and the second connecting pipe are fixed. The clamping collar can prevent the first connecting pipe and the second connecting pipe from coming out of the connector body, thus improving the stability of the pipeline installation.

[0014] Furthermore, the outer wall of the clamping collar is provided with several reinforcing ribs.

[0015] The outer wall of the crimping collar is provided with several reinforcing ribs, which can make the crimping collar less prone to deformation and ensure the stability of pipeline installation.

[0016] Furthermore, several elastic claws are evenly distributed and installed on the connector body around the axis of the conveying pipe.

[0017] Several elastic claws are evenly distributed and installed on the connector body around the axis of the conveying pipe. One end of each elastic claw is connected to the connector body, and the other end is set at an angle to the connector body and can undergo elastic deformation. The mounting ring can be installed at a predetermined installation position on the pipeline. When it is necessary to fix the pipeline, the connector body is inserted into the preset mounting ring until the elastic claws also abut into the preset mounting ring to complete the position fixation of the connector body, thereby fixing the position of the pipeline assembly.

[0018] Furthermore, a limiting plate is provided on the connector body.

[0019] By providing a limiting plate on the connector body, the situation where the connector body is inserted too deeply into the preset installation ring and cannot be removed can be avoided.

[0020] The beneficial effects of this application are:

[0021] 1. The sealing block is inserted into the first connecting pipe or the second connecting pipe, and the sealing block abuts against the inner wall of the first connecting pipe or the second connecting pipe, so as to achieve the sealing and stability of the pipe body when the connector body is connected to the first connecting pipe or the second connecting pipe.

[0022] 2. The outer diameter of the sealing block near the opening of the conveying pipe is smaller, making it easier and more efficient for the user to insert the sealing block into the first or second connecting pipe when fitting the first or second connecting pipe onto the conveying pipe.

[0023] 3. The crimping collar can prevent the first and second connecting pipes from coming out of the connector body, thus improving the stability of the pipeline installation. Attached Figure Description
