Description

Technical Field

[0001] The utility model relates to the field of automobile equipment, in particular to a high-seismic and high-sealing automobile air-conditioning pipeline assembly. Background Technique

[0002] The automobile air-conditioning pipeline is a channel that connects various components of the air conditioner and enables the refrigerant to circulate, and is the "vein" of the automobile air-conditioning system.

[0003] The automobile air-conditioning system realizes the effective adjustment of the temperature inside the vehicle through the coordinated work of core components such as the compressor, condenser, and evaporator. And the key part that connects these components and enables the refrigerant to circulate and complete heat exchange is the automobile air-conditioning pipeline.

[0004] The automobile pipeline is composed of a rubber hose and a metal head. Generally, at the connection, the metal head is extruded on the outside of the rubber hose. Since the connection position between the hose and the metal head is a soft-hard joint position, it is easy to leak, and air is also easy to enter the pipeline interior through the joint position, affecting the normal operation of the entire automobile air conditioner. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-seismic and high-sealing automobile air-conditioning pipeline assembly to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-seismic and high-sealing automobile air-conditioning pipeline assembly, including a metal head and a rubber pipeline. The metal head is fixed on one side of the rubber pipeline by extrusion. A first sleeve is movably sleeved on the outside of the metal head. A second sleeve is movably sleeved on the outside of the rubber pipeline. An extrusion mechanism is arranged on one side of the second sleeve. A hollow rubber block is slidably arranged inside the first sleeve. An extension ring is fixedly arranged around the outside of the second sleeve. The extension ring is threadedly sleeved on the outside of the first sleeve. A limiting mechanism for conveniently restricting the position of the first sleeve is arranged on one side of the first sleeve.

[0007] Preferably, the extrusion mechanism includes an extrusion cylinder and an extrusion ring. The extrusion ring is slidably sleeved outside the rubber pipe, and the extrusion ring is slidably arranged inside the second sleeve. The extrusion cylinder is inserted through the thread on the inner side wall of the second sleeve. During use, the first sleeve and the second sleeve are respectively sleeved outside the metal head and the rubber pipe. When the metal head and the rubber pipe are squeezed and fixed, at this time, move the first sleeve and the second sleeve so that the first sleeve and the second sleeve are spliced with each other and cover the outside of the connection between the metal head and the rubber pipe. After splicing, rotate the second sleeve so that the extension ring is installed outside the first sleeve through the thread, so that the second sleeve and the first sleeve are fixed to each other. Then rotate the extrusion cylinder so that the extrusion cylinder moves along the inside of the second sleeve and squeezes the extrusion ring until the extrusion ring squeezes the hollow rubber block, so that the hollow rubber block deforms away from the second sleeve and thus clings to the outside of the connection between the metal head and the rubber pipe, which is convenient to improve the sealing performance of the connection and thus prevent leakage and air from entering.

[0008] Preferably, the limiting mechanism includes elastic pieces and a movable ring. There are three elastic pieces, which are fixed equidistantly on one side of the first sleeve. The movable ring is sleeved outside the elastic pieces through the thread. When the connection between the first sleeve and the second sleeve is completed, at this time, rotate the movable ring so that the movable ring moves along the elastic pieces and squeezes the elastic pieces, so that the elastic pieces are close to the outside of the extrusion metal head. In this way, the position of the first sleeve is fixed by extrusion to prevent the device from detaching from the connection position of the metal head and the rubber pipe.

[0009] Preferably, the hollow rubber block is annular and sleeved outside the metal head.

[0010] Preferably, the extrusion cylinder is movably sleeved outside the rubber pipe.

[0011] Preferably, the side of the elastic piece away from the metal head is an inclined surface.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. During use of the present utility model, the first sleeve and the second sleeve are respectively sleeved outside the metal head and the rubber pipe. When the metal head and the rubber pipe are squeezed and fixed, at this time, move the first sleeve and the second sleeve so that the first sleeve and the second sleeve are spliced with each other and cover the outside of the connection between the metal head and the rubber pipe. After splicing, rotate the second sleeve so that the extension ring is installed outside the first sleeve through the thread, so that the second sleeve and the first sleeve are fixed to each other. Then rotate the extrusion cylinder so that the extrusion cylinder moves along the inside of the second sleeve and squeezes the extrusion ring until the extrusion ring squeezes the hollow rubber block, so that the hollow rubber block deforms away from the second sleeve and thus clings to the outside of the connection between the metal head and the rubber pipe, which is convenient to improve the sealing performance of the connection and thus prevent leakage and air from entering;

[0014] 2. After the connection between the first sleeve and the second sleeve of the present utility model is completed, rotate the movable ring at this time, so that the movable ring moves along the elastic piece and squeezes the elastic piece, thereby making the elastic piece approach the outside of the extrusion metal head. In this way, the position of the first sleeve is fixed by extrusion, preventing the device from detaching from the connection position between the metal head and the rubber pipe.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5, the utility model provides a high-seismic and high-sealing automobile air-conditioning pipeline assembly, which includes a metal head 1 and a rubber pipeline 2. The metal head 1 is fixed on one side of the rubber pipeline 2 by extrusion. A first sleeve 4 is movably sleeved outside the metal head 1. A second sleeve 3 is movably sleeved outside the rubber pipeline 2. There is an extrusion mechanism on one side of the second sleeve 3. A hollow rubber block 7 slides inside the first sleeve 4. The hollow rubber block 7 is annular and sleeved outside the metal head 1. An extension ring 8 is fixedly welded around the outside of the second sleeve 3. The extension ring 8 is threadedly sleeved outside the first sleeve 4. There is a limiting mechanism on one side of the first sleeve 4 to conveniently limit the position of the first sleeve 4.

[0023] The extrusion mechanism includes an extrusion cylinder 10 and an extrusion ring 9. The extrusion ring 9 is slidably sleeved outside the rubber pipeline 2 and slides inside the second sleeve 3. The extrusion cylinder 10 is inserted through the inner side wall of the second sleeve 3 by threads and is movably sleeved outside the rubber pipeline 2. During use, the first sleeve 4 and the second sleeve 3 are respectively sleeved outside the metal head 1 and the rubber pipeline 2. After the metal head 1 and the rubber pipeline 2 are fixed by extrusion, at this time, move the first sleeve 4 and the second sleeve 3 so that the first sleeve 4 and the second sleeve 3 are spliced with each other and cover the outside of the connection between the metal head 1 and the rubber pipeline 2. After splicing, rotate the second sleeve 3 so that the extension ring 8 is installed outside the first sleeve 4 by threads, so that the second sleeve 3 and the first sleeve 4 are fixed to each other. Then rotate the extrusion cylinder 10 so that the extrusion cylinder 10 moves along the inner side of the second sleeve 3 and extrudes the extrusion ring 9 until the extrusion ring 9 extrudes the hollow rubber block 7, causing the hollow rubber block 7 to deform away from the second sleeve 3 side, so as to closely adhere to the outside of the connection between the metal head 1 and the rubber pipeline 2, which is convenient to improve the sealing performance of the connection, thereby preventing leakage and air entry.

[0024] The limiting mechanism includes elastic pieces 5 and a movable ring 6. There are three elastic pieces 5, which are fixedly welded at equal intervals on one side of the first sleeve 4. The movable ring 6 is threadedly sleeved outside the elastic pieces 5. The side of the elastic piece 5 away from the metal head 1 is an inclined surface. After the connection between the first sleeve 4 and the second sleeve 3 is completed, at this time, rotate the movable ring 6 so that the movable ring 6 moves along the elastic piece 5 and extrudes the elastic piece 5, so that the elastic piece 5 approaches and presses the outside of the metal head 1. In this way, the position of the first sleeve 4 is fixed by extrusion, preventing the device from detaching from the connection position of the metal head 1 and the rubber pipeline 2.

[0025] Working principle: During use, the first sleeve 4 and the second sleeve 3 are respectively sleeved outside the metal head 1 and the rubber pipe 2. After the metal head 1 and the rubber pipe 2 are squeezed and fixed, the first sleeve 4 and the second sleeve 3 are moved at this time so that the first sleeve 4 and the second sleeve 3 are spliced with each other and cover the outside of the connection between the metal head 1 and the rubber pipe 2. After splicing, the second sleeve 3 is rotated so that the extension ring 8 is installed outside the first sleeve 4 through threads, so that the second sleeve 3 and the first sleeve 4 are fixed to each other. Then the extrusion cylinder 10 is rotated so that the extrusion cylinder 10 moves along the inner side of the second sleeve 3 and extrudes the extrusion ring 9 until the extrusion ring 9 extrudes the hollow rubber block 7, so that the hollow rubber block 7 deforms away from the second sleeve 3 and thus closely adheres to the outside of the connection between the metal head 1 and the rubber pipe 2, which is convenient for improving the sealing performance of the connection and thus preventing leakage and air entry; when the connection between the first sleeve 4 and the second sleeve 3 is completed, the movable ring 6 is rotated at this time so that the movable ring 6 moves along the elastic piece 5 and extrudes the elastic piece 5, so that the elastic piece 5 approaches and presses the outside of the metal head 1. In this way, the position of the first sleeve 4 is fixed by extrusion to prevent the device from detaching from the connection position of the metal head 1 and the rubber pipe 2.
