Description

Technical Field

[0001] The utility model belongs to the technical field, and specifically relates to a vehicle-mounted filling sponge. Background Art

[0002] It is divided into high-pressure pipe and low-pressure pipe. Under the action of the blower, the air is cooled by the evaporator and then blown into the car to achieve cooling. The refrigerant in the evaporator vaporizes into gas. The gas is compressed by the compressor and becomes high-temperature and high-pressure gas. It enters the condenser through the high-pressure pipe and condenses into liquid. After being dried by the liquid storage drying filter, it flows to the evaporator through the high-pressure pipe through the expansion valve.

[0003] The purpose of wrapping the low-pressure pipe of the car air conditioner with sponge is to prevent the copper pipe from frosting, which is to keep the heat and isolate the air. Because the temperature of the refrigerant is very low, the low-pressure pipe will definitely frost if it is in direct contact with the air. Most of the insulation treatment methods are to directly wrap the filling sponge, but simple wrapping is fixed with a strap or tape. During the fixing process, some parts of the pipeline will be exposed. At the same time, the pipeline has a bending structure, which also brings technical difficulties of bending and damage to the subsequent bending and wrapping of the filling sponge.

[0004] Therefore, according to the above requirements, the present application provides a vehicle-mounted filling sponge that can be adaptively installed according to the bending structure of the low-pressure pipeline. During the filling process, the sponge can adapt to the filling sponge structure with a corrugated structure to complete the wrapping treatment of the pipeline bending without dead angles, solving the technical problems of bending and breaking or incomplete wrapping of the bent pipeline in the process of wrapping the filling sponge in the past; at the same time, the present application also uses the tightening treatment solution of the multi-section joint structure to strengthen the installation structure of the vehicle-mounted filling sponge.

[0008] Furthermore, a locking knob is installed at the inner end of the closing sleeve, and the locking knob is locked and docked with the outer ring of the closing sleeve.

[0009] Furthermore, the corrugated filling sleeve comprises a corrugated layer; the front and rear ends of the corrugated layer are integrally extended with extension edges, and the extension edges extend into the inner ends of the first filling sponge tube and the second filling sponge tube;

[0010] An interlayer is retained in the corrugated layer and the extended edge, and the interlayer is filled with a third filling sponge.

[0011] Furthermore, a tightening groove is left on the extended edge, and the inner ends of the first filling sponge tube and the second filling sponge tube are tightened and contacted with the extended edge through buckles, and the buckles are countersunk buckled along the tightening groove.

[0012] Furthermore, a burr layer is retained on the inner wall of the expansion sleeve, and the burr layer is in frictional contact with the low-pressure pipe of the vehicle air conditioner.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a vehicle-mounted filling sponge includes a first filling sponge tube and a second filling sponge tube; the first filling sponge tube 3 and the second filling sponge tube 6 are mounted on the low-pressure pipe of the vehicle air conditioner, and a corrugated filling sleeve 4 is installed and docked between the first filling sponge tube 3 and the second filling sponge tube 6; wherein, the filling sponge has three groups, namely the first filling sponge tube 3, the second filling sponge tube 6 and the corrugated filling sleeve 4, and the first filling sponge tube 3 and the second filling sponge tube 6 can be directly installed on the low-pressure pipe of the vehicle air conditioner, and the corrugated structure of the corrugated filling sleeve 4 itself can be adaptively bent and wrapped according to the bending structure of the pipe without destroying its own integrity.

[0022] The first filling sponge tube 3 and the second filling sponge tube 6 are provided with an expansion sleeve 2 at their outer ends, the expansion sleeve 2 extends into the closing sleeve 1, and the closing sleeve 1 filled with the expansion sleeve 2 is fixedly connected to the low-pressure pipe of the vehicle air conditioner. The expansion sleeve 2 is a fastening structure for auxiliary installation, and the expansion sleeve 2 cooperates with the closing sleeve 1 to complete the fastening installation process, so as to prevent the first filling sponge tube 3 and the second filling sponge tube 6 from shifting due to looseness after installation.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a locking knob 7 is installed at the inner end of the closing sleeve 1, and the locking knob 7 is locked and connected with the outer ring of the closing sleeve 1. The locking knob 7 is a fastening structure for reinforcing the closing sleeve 1 from the outside.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the corrugated filling sleeve 4 includes a corrugated layer 11; the front and rear ends of the corrugated layer 11 are integrally extended with an extension edge 10, and the extension edge 10 extends into the inner ends of the first filling sponge tube 3 and the second filling sponge tube 6; wherein the corrugated layer 11 is a structure that is adaptively bent in coordination with the bending pipeline. The corrugated layer 11 is connected to the first filling sponge tube 3 and the second filling sponge tube 6 by the extension edge 10.

[0025] The corrugated layer 11 and the extended edge 10 retain an interlayer, which is filled with a third filling sponge 9. The third filling sponge 9 retained inside the corrugated layer 11 and the extended edge 10 also has the protective effect of the first filling sponge tube 3 and the second filling sponge tube 6, avoiding the corrugated layer 11 from being damaged and affecting the protective effect of the overall structure.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a tightening groove 12 is left on the extension edge 10, and the inner ends of the first filling sponge tube 3 and the second filling sponge tube 6 are tightened and contacted with the extension edge 10 through the buckle 5, and the buckle 5 is countersunk buckled along the tightening groove 12. Among them, the tightening groove 12 is a limiting structure for cooperating with the buckle 5 to reinforce the docking.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the expansion sleeve 2 retains a burr layer 8, and the burr layer 8 is in frictional contact with the low-pressure pipe of the vehicle air conditioner. The burr layer 8 can increase the friction force, and the burr layer 8 can be processed by sandpaper or other grinding equipment to make the surface rough.
