Description

Technical Field

[0001] The utility model belongs to the technical field of cold circulation pipe manufacturing, and in particular relates to a cold circulation pipeline based on a refrigerator. Background Art

[0002] The refrigerator cold circulation pipe is an important part of the refrigerator refrigeration system. It is responsible for transporting the refrigerant from the condenser to the evaporator to complete the refrigeration cycle. These cold circulation pipes tightly connect the condenser and evaporator together to form a closed circulation system.

[0003] Common cold circulation pipelines are affected by the strong vibrations generated by the compressor during operation and will also vibrate synchronously. Long-term high-intensity vibrations will damage and cause the cold circulation pipelines themselves and various pipe fittings to fall off. At the same time, the cold circulation pipelines generate a lot of noise when vibrating, affecting people's normal rest. Utility Model Content

[0004] The purpose of the utility model is to provide a refrigerator-based cold circulation pipeline in order to solve the problems that the common cold circulation pipeline may cause damage and detachment to the cold circulation pipeline itself and various pipe fittings due to long-term high-intensity vibration, and generate loud noise during vibration.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: it includes a pipeline body, a buffer pipe fitting is provided on the outside of the pipeline body, a spiral drainage rod is fixedly provided on the inside of the pipeline body, the buffer pipe fitting includes a mounting tube, an annular clamping plate is provided on the open end of the mounting tube, the annular clamping plate is connected to the mounting tube and the pipeline body through a buckle, and a vibration conduction component is provided on the inside of the mounting tube.

[0006] Furthermore, the vibration conduction component includes a fixing ring, which is connected to the pipe body by a snap-fit, and a plurality of conduction rods are fixedly provided on the outside of the fixing ring, and the conduction rods penetrate the mounting tube, and vibration-dissipating rubber is provided at one end of the conduction rods, and a spring is provided on the outside of the conduction rods, and the spring is located between the inner wall of the mounting tube and the outer wall of the fixing ring.

[0007] Furthermore, the vibration-dissipating rubber comprises a U-shaped rubber block, a connecting block is provided on the side of the U-shaped rubber block, and the connecting block is connected to the conduction rod by insertion and fastened with screws.

[0008] Furthermore, the inner side of the installation tube is filled with sound-proof cotton.

[0009] Furthermore, the fixing ring and the conducting rod are both made of lightweight metal.

[0010] Beneficial effects: The utility model has reasonable design and has the following beneficial effects:

[0011] 1. In the scheme of the utility model, when the pipeline body vibrates, the vibration is transmitted to the vibration-dissipating rubber through the fixing ring and the transmission rod, and then dissipated into the outside air through the vibration of the U-shaped rubber block. The spring transmits the scattered vibration to the installation tube, thus avoiding damage caused by long-term high-intensity vibration of the pipeline;

[0012] 2. In the present invention, the noise-reducing cotton installed in the tube further reduces the noise caused by vibration. The cold circulation pipe made of lightweight metal has a smaller mass and better noise-reducing performance. The combination of the two can reduce the noise generated by the vibration of the cold circulation pipe.

[0013] 3. In the solution of the utility model, the spiral drainage rod can improve the strength of the pipeline body while draining the refrigerant, avoiding the decrease in structural strength due to the use of lightweight metal. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Combination Figures 1 to 4A cold circulation pipeline based on a refrigerator is shown, comprising a pipeline body 1, a buffer pipe fitting 2 is arranged on the outer side of the pipeline body 1, a spiral drainage rod 3 is fixedly arranged on the inner side of the pipeline body 1, the buffer pipe fitting 2 comprises a mounting tube 21, an annular clamping plate 22 is arranged at the open end of the mounting tube 21, the annular clamping plate 22 is connected to the mounting tube 21 and the pipeline body 1 by a snap, and a vibration conduction component 23 is arranged on the inner side of the mounting tube 21.

[0024] Among them, the vibration conduction component 23 includes a fixing ring 231, which is connected to the pipeline body 1 by a snap-fit, and a plurality of conduction rods 232 are fixedly arranged on the outside of the fixing ring 231, and the conduction rods 232 penetrate the mounting tube 21, and a vibration-dissipating rubber 233 is arranged at one end of the conduction rod 232, and a spring 234 is arranged on the outside of the conduction rod 232, and the spring 234 is located between the inner wall of the mounting tube 21 and the outer wall of the fixing ring 231. The vibration of the pipeline body 1 is transmitted to the vibration-dissipating rubber 233 through the fixing ring 231 and the conduction rod 232, and then dissipated into the outside air. The spring 234 can transmit the scattered vibration to the mounting tube 21, and at the same time, it can reduce the travel distance of the shaking of the fixing ring 231, and play a role of partial support and buffering.

[0025] The vibration-dissipating rubber 233 includes a U-shaped rubber block 2311. A connecting block 2312 is provided on the side of the U-shaped rubber block 2311. The connecting block 2312 is connected to the conductive rod 232 by insertion and fastened with screws. Since the U-shaped rubber block 2311 is made of rubber, the sound is small when it vibrates.

[0026] The inside of the installation tube 21 is filled with sound-proof cotton, which further reduces the noise caused by vibration.

[0027] The fixing ring 231 and the conducting rod 232 are both made of lightweight metal, which reduces the mass of the cold circulation pipeline and enhances the quietness performance.

[0028] Working principle: When the utility model is in use, when the pipe body 1 vibrates, the vibration of the pipe body 1 is transmitted to the vibration-dissipating rubber 233 through the fixing ring 231 and the conduction rod 232, and then dissipated to the outside air through the vibration of the U-shaped rubber block 2311. The spring 234 transmits the scattered vibration to the mounting tube 21, and at the same time can reduce the travel distance of the shaking of the fixing ring 231, playing a role of partial support and buffering. The sound-proof cotton in the mounting tube 21 further reduces the noise caused by vibration. The cold circulation pipe made of lightweight metal has a smaller mass and better sound-proof performance. The spiral drainage rod 3 can enhance the strength of the pipe body 1 while draining the refrigerant, avoiding the decrease in structural strength due to the use of lightweight metal.
