Description

Technical Field

[0001] This application relates to the field of air conditioning piping, and more particularly to a noise-reducing air conditioning piping installation assembly. Background Technology

[0002] The automotive air conditioning piping assembly is a core component of the automotive air conditioning system. It is a complete piping system integrated from multiple parts, mainly including aluminum pipes, connectors, air conditioning hoses, corrugated pipes, aluminum sleeves, filler caps, sight glasses, pressure switches, O-rings, and plastic caps. It is used to connect key components such as the compressor, condenser, and evaporator, forming a closed refrigerant circulation path. It is responsible for transporting refrigerant and ensuring pressure balance and circulation efficiency among the components of the air conditioning system. High pressure (H) and low pressure (L) markings are used to distinguish the pipe pressure status, which is convenient for checking the system pressure during maintenance. In conventional automotive air conditioning piping installation, the two ends of the low-pressure pipe are connected to the evaporator and the compressor, respectively. The low-temperature, low-pressure gaseous refrigerant, which has absorbed heat and vaporized in the evaporator, is transported back to the compressor through the low-pressure pipe to complete the refrigeration cycle. One end of the low-pressure pipe is connected to the high-pressure pipe, which connects the condenser and the compressor and is responsible for transporting refrigerant from the compressor to the condenser.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional automotive air conditioning pipes are often installed by placing them directly inside the car. This can cause vibrations in the pipes during vehicle operation and the flow of refrigerant, resulting in noise.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of noise generated by external vibrations in air conditioning pipes after installation, this application provides a noise-reducing air conditioning pipe installation assembly.

[0006] The noise reduction air conditioning pipe installation assembly provided in this application adopts the following technical solution:

[0007] A noise-reducing air conditioning pipe installation assembly includes a low-pressure pipe and a connecting bracket. A high-pressure pipe is provided at the bottom end of the low-pressure pipe. Two mounting grooves are formed on the inner wall of the connecting bracket, and the two mounting grooves are symmetrically distributed about the connecting bracket. A shock-absorbing spring is fixedly connected to one end of the connecting bracket. A fixing bracket is fixedly installed at the end of the shock-absorbing spring away from the connecting bracket. A number of mounting bolts are snapped into the inner wall of the fixing bracket. The inner wall of the mounting groove is movably connected to the surfaces of the low-pressure pipe and the high-pressure pipe. The center of the shock-absorbing spring and the center of the fixing bracket are on the same straight line. The number of mounting bolts are divided into two groups, and the two groups of mounting bolts are symmetrically distributed about the fixing bracket.

[0008] Preferably, the inner wall of the mounting groove is slidably connected to a limiting block, the size of the limiting block surface is adapted to the size of the inner wall of the mounting groove, and the surfaces of the two limiting blocks are respectively movably installed on the surfaces of the low-pressure pipe and the high-pressure pipe.

[0009] Preferably, both the limiting block and the mounting groove are fixedly connected to an auxiliary piece, the surface of the auxiliary piece being adapted to the size and specifications of the limiting block surface, and the auxiliary piece being a rubber sheet.

[0010] Preferably, the inner wall of the limiting block is threaded with a threaded rod, the bottom end of the threaded rod is rotatably connected to the inner wall of the connecting frame, and a rotating block is fixedly installed on the top of the threaded rod, the center of the rotating block and the center of the threaded rod are on the same straight line.

[0011] Preferably, both the low-pressure pipe and the high-pressure pipe are fixedly connected to an installation box. A rotating disk is rotatably installed on the inner wall of the installation box. The rotating disk has two connection holes. A filter block is snapped into the inner wall of the connection hole. The size and specifications of the filter block surface are adapted to the size and specifications of the inner wall of the connection hole.

[0012] Preferably, the dimensions of the rotating disk surface are adapted to the dimensions of the inner wall of the mounting box, and the two connecting holes are symmetrically distributed about the rotating disk axis.

[0013] Preferably, a threaded block is threaded onto the inner wall of the connecting hole, the surface of the threaded block engaging with the inner wall of the mounting box, and the center of the threaded block and the center of the filter block are on the same straight line.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By connecting the mounting groove inside the connecting frame to the surfaces of the low-pressure and high-pressure pipes, and with a fixing frame connected to one end of the connecting frame via a shock-absorbing spring, several mounting bolts are snapped into the inner wall of the fixing frame to secure the surfaces of the low-pressure and high-pressure pipes. The shock-absorbing spring counteracts the vibrations generated by the connecting frame. A limit block is slidably connected to the inner wall of the mounting groove to fix the low-pressure and high-pressure pipes within the mounting groove. A threaded rod is threadedly connected to the inner wall of the limit block, and a rotating block is fixedly installed at the top of the threaded rod to control the rotation of the threaded rod, thereby moving and fixing the limit block. Rubber auxiliary plates are fixedly connected to both the limit block and the inner wall of the mounting groove to prevent wear on the low-pressure and high-pressure pipes. Compared to existing technologies, this method effectively improves the noise reduction effect of the air conditioning piping.

Two connection holes are provided on the inner wall of the rotating disk to facilitate replacement of the filter block by rotating the disk and removing it from the connection hole. Threaded blocks are threaded into the inner wall of the connection holes to facilitate removal of the used filter block. This effectively improves the performance of the device.
