Description

Technical Field

[0001] The utility model belongs to the technical field of automobile air-conditioning pipelines, and particularly relates to an automobile air-conditioning compressor pipeline assembly. Background Art

[0002] In an automobile air conditioner, a compressor pipeline is used to connect a compressor and a condenser. Constrained by the complex environment and space in the front cabin of the automobile, the compressor pipeline passes through the gap between the front enclosure of the cab and the front enclosure grille, or a hole is drilled in the cab beam, and the compressor pipeline passes through the hole. After installation, the stability is poor. The compressor delivers high-pressure gas with a fast flow rate, which has a large impact on the pipeline, easily causing the compressor pipeline to shake. Also, during the vehicle driving process, due to reasons such as compressor vibration and bumps, the compressor pipeline is also prone to shaking and collision damage, which not only affects the service life but also generates noise, affecting the driving experience. Summary of the Invention

[0003] The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art, and provide an automobile air-conditioning compressor pipeline assembly, which has a novel structure, high layout stability, is not prone to free shaking, and is reliable in use.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An automobile air-conditioning compressor pipeline assembly, comprising: an aluminum pipe and a rubber pipe, characterized in that: a support seat is provided on the aluminum pipe, and the support seat includes an upper clamp block, a lower clamp block, a threaded column and a base. The lower clamp block is provided at one end of the threaded column, the base is screwed at the other end of the threaded column, and the upper clamp block and the lower clamp block are fixedly connected through a fixing component so that the upper clamp block cooperates with the lower clamp block to clamp the aluminum pipe. This compressor pipeline assembly has a novel structure, high layout stability, is not prone to free shaking, and is reliable in use.

[0006] Further, the aluminum pipe is provided with a reduced diameter end that cooperates with and sleeves the rubber pipe. An inner groove is provided on the reduced diameter end. The aluminum pipe presses the end of the rubber pipe into the inner groove through a snap ring, so that the aluminum pipe limits and connects the rubber pipe. The two are tightly connected, not prone to free disconnection, and there is no air leakage or liquid leakage at the connection. They can be detachably separated, which is flexible and convenient.

[0007] Further, a protective cover is threadedly connected to the aluminum pipe. The protective cover covers the snap ring through an outward expansion part. The outward expansion part can resist external direct impact for the snap ring, avoiding damage to the snap ring due to impact and affecting the fastening effect. The outward expansion part can also prevent the snap ring from freely coming outwards, preventing the snap ring from falling off freely due to vibration. The snap ring can always hold the rubber pipe, and the rubber pipe cannot be separated from the reduced diameter end, improving the connection reliability between the aluminum pipe and the rubber pipe; rotating the protective cover in the reverse direction until the snap ring is exposed, and removing the snap ring can disassemble the aluminum pipe and the rubber pipe, which is flexible and convenient.

[0008] Furthermore, the fixing component includes an end bolt and a lock nut. The end bolt passes through the ear blocks of the upper clamping block and the lower clamping block, and the lock nut is screwed onto the end bolt. The lock nut cooperates with the end of the end bolt to clamp the ear blocks of the upper clamping block and the lower clamping block, which has high reliability, is convenient for disassembly and assembly, and is flexible and convenient.

[0009] Furthermore, a limit nut is screwed onto the threaded post. The limit nut is used to prevent the base from freely rotating upward along the threaded post, so that the bottom surface of the base is kept in close contact with the supporting surface, without affecting the continuous supporting effect of the supporting seat on the aluminum tube.

[0010] Furthermore, rubber pads are provided on the inner walls of the upper clamping block and the lower clamping block. On the one hand, it improves the tightness of the contact between the upper clamping block and the lower clamping block and the aluminum tube, and relative movement is not likely to occur, and the connection is reliable. On the other hand, it plays a protective role on the surface of the aluminum tube, avoiding leaving indentations on the surface of the aluminum tube due to excessive clamping force.

[0011] Furthermore, a shock absorber is provided on the aluminum tube. The shock absorber plays an elastic supporting role on the aluminum tube, has a good isolation effect on the mechanical vibration transmitted by the aluminum tube, and has a significant effect on reducing noise.

[0012] Furthermore, a galvanized layer is coated on the inner wall of the aluminum tube, which improves the corrosion resistance of the inner wall of the aluminum tube, is not easily corroded and rusted, and has a long service life.

[0013] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0014] 1. The upper clamping block cooperates with the lower clamping block to clamp the aluminum tube, and then the base is rotated so that its bottom surface abuts against the mounting surface on the cab panel. The cab panel gives support to the aluminum tube through the support seat, restricting the free swaying of the aluminum tube, thereby improving the stability of the pipeline assembly, and being applicable to installation spaces of different sizes, with strong applicability.

[0015] 2. The disassembly and assembly between the aluminum tube and the rubber tube are convenient. Instead of the bonding fixing method, the end of the rubber tube is pressed into the inner groove of the reduced diameter end through a snap ring, so that the aluminum tube is limited to connect with the rubber tube, and the two are tightly connected and not easily separated freely. Leakage of air or liquid is not likely to occur at the connection, and they can be detachably separated, which is flexible and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
