Embodiment Construction

[0012] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0013] like figure 2 As shown, the present invention mainly includes a pressure plate body 1, which is provided with a joint hole 2 with an internal tooth structure, and the joint hole 2 and the expanded aluminum tube form a riveted connection through internal teeth, avoiding the occurrence of welded joints. The risk of solder joint leakage; convenient processing and production, lower production costs.

[0014] The two ends of the pressing plate body 1 are respectively two circular arcs, one large and one small.

[0015] The internal teeth of the joint hole 2 are evenly distributed.

[0016] The working principle of the present invention is: when connecting the aluminum pipes, it is only necessary to connect the expanded aluminum pipes through the internal teeth of the joint hole 2 to form a riveting connection, and the connection is formed convenie...

Abstract

The invention relates to a pressure plate joint with internal teeth for automobile air conditioner pipelines, particularly is a pressure plate joint used for allowing various pipelines of an automobile air conditioner to be connected, and belongs to the technical field of connecting pieces. The pressure plate joint comprises a pressure plate body, wherein a joint hole adopting an internal tooth-shaped structure is formed in the pressure plate body; the two ends of the pressure plate body are a large circular arc and a small circular arc respectively; internal teeth of the joint holes are distributed uniformly. The pressure plate joint has a simple, compact and reasonable structure, and avoids the risk of welding spot leakage caused by the welding and processing, the production cost is reduced, and the use is convenient.

Description

technical field [0001] The invention relates to a pressure plate joint of an automobile air conditioner pipeline with internal teeth, in particular for connecting various pipelines of an automobile air conditioner, and belongs to the technical field of connectors. Background technique [0002] Since the components and assemblies of the automobile air conditioner are generally scattered and installed in various parts of the automobile, when the automobile air conditioner is turned off, these components and assemblies are connected to form an automobile air conditioning system. Automobile air-conditioning pipelines are generally composed of aluminum tubes, air-conditioning rubber hoses and pipeline accessories. Among them, the diameters of various pipes are different, and the aluminum pipes are generally connected with the aluminum pipes or other parts in the form of pressing plates. like figure 1 As shown, there is a smooth aluminum pipe connection hole on the joint of the ...
