Automobile air conditioning pipe riveting structure capable of being limited and riveting method thereof

Abstract

The invention provides an automobile air conditioning pipe riveting structure capable of being limited and a riveting method thereof. The automobile air conditioning pipe riveting structure is provided with a joint body. The joint body tail of the joint body and the rubber pipe of an automobile air conditioning pipeline are integrally socket-connected. A plurality of teeth are produced at the inlet section of the joint body tail. A limiting bulge is arranged at the tail section of the joint body tail. The rubber pipe is sheathed on the joint body tail. A fastening piece is sheathed on the external surface of the rubber pipe. One end of the fastening piece resists against the limiting bulge. The fastening piece tightly connects the rubber pipe with the joint body tail. Since inclined teeth and the limiting bulge are arranged on the joint body tail, on one hand, the contact area between the rubber pipe and the joint body is increased; and on the other hand, the position of the fastening piece can be conveniently limited when the fastening piece is fastened and the practical value is greater.

Description

technical field [0001] The invention relates to the field of riveting rubber hoses of automobile air-conditioning pipelines, in particular to a position-limitable riveting structure of automobile air-conditioning pipes and a riveting method thereof. Background technique [0002] The interior of the automotive air-conditioning pipeline needs to bear a certain pressure, which is generally 0.8-1.2MP. The existing air-conditioning manufacturers have no effective way to improve the riveting structure of the aluminum sleeve and the rubber hose. At present, there are mainly The following problems: First, when the fasteners are riveted, it is easy to cause the riveting not to be tight, and the fasteners become loose, which affects the product quality; second, it is not easy to limit the position when the fasteners are crimped, resulting in increased labor intensity for the staff The 3rd, the contact area of ​​sebific hose and joint body is limited, can cause riveting pressure not ti...

Problems solved by technology

[0002] The interior of the automotive air-conditioning pipeline needs to bear a certain pressure, which is generally 0.8-1.2MP. The existing air-conditioning manufacturers have no effective way to improve the riveting structure of the aluminum sleeve and the rubber hose. At present, there are mainly The following problems: First, when the fasteners are riveted, it is easy to cause the riveting not to be tight, and the fasteners become loose, which affects the product quality; second, it is not easy to limit the position when the fasteners are crimped, resulting in increased labor intensity for the staff ; The third is that the contact area between the rubber hose and the joint body is limited, which will cause the phenomenon that the riveting is not tight and the rubber hose is easy to pull out, which will affect the product quality and cause the car air-conditioning compressor to not work normally
