Problems solved by technology

[0005] In the prior art vacuum pipeline joints, the connection fit is generally a transition fit or an interference fit, and there is also a complex and precise connection method combining a clearance fit and a spring ball. The former is time-consuming to install and operate, and the latter has a complicated structure and is expensive.

Abstract

The invention relates to a vacuum pipeline joint and belongs to the technical field of machines. According to the technical scheme, the vacuum pipeline joint capable of being rapidly mounted and demounted without a tool is characterized in that a pipeline joint is constituted by a male joint body and a female joint body; the male joint body or the female joint body is provided with at least one ormore than one magnetic attraction piece, or the male joint body and the female joint body are each provided with the at least one or more than one magnetic attraction piece. The male joint body or the female joint body is provided with a sealing rubber ring. When the pipeline joint is connected, the end faces of the magnetic attraction pieces attract with the internal end face of the female jointbody, and the end face of the male joint body makes contact with the sealing rubber ring. The other end of the male joint body is connected with a vacuum pump air suction port through a pipeline. Theother face of the male joint body is fixedly connected with the outer wall of a vacuum box provided with a through hole. During working of a vacuum pump, the end face of the male joint body is slowlypressed into the end face of the sealing rubber ring along with degreasing of the vacuum degree, so that the end face of the male joint body is changed, and the vacuum state rapidly reaches.

Description

technical field [0001] The invention relates to a joint of a vacuum pipeline, which belongs to the technical field of machinery. Background technique [0002] Handicraft industry and industrial product hand model rapid prototyping, LED lamps, plastic toys, transformer potting, silicone rubber molds and other industries that have high requirements for the degassing of the agitator often need to use a vacuum box, which is usually threaded or The clamp establishes a pipeline fixed connection between the above-mentioned vacuum box and the vacuum pump; [0003] Generally speaking, the volume of the object to be evacuated is slightly smaller than the volume of the vacuum box, which can maximize the efficiency of the vacuum pump and save energy; of course, a vacuum pump can be connected to a vacuum box with different volumes to solve this problem. This solution is bound to occupy a relatively large space; [0004] The principle of process design (tooling design) in the mass produ...
