Abstract

The invention provides a telescopic block assembly and a door opening and closing device. The telescopic block assembly comprises a base and a moving block structure, wherein the base comprises an accommodating cavity, an opening of the accommodating cavity is located in the side face of the base, the moving block structure comprises a moving block and an elastic piece, the moving block is at least partially located in the accommodating cavity, and the elastic piece is located in the accommodating cavity and arranged between the moving block and the inner wall of the accommodating cavity in anabutting mode, so as to provide elastic force for the moving block. According to the technical scheme, the problem of non-tight closing of a door opening and closing device in the prior art is effectively solved.

Description

technical field [0001] The invention relates to a door opening and closing device, in particular to a telescopic block assembly and a door opening and closing device. Background technique [0002] In order to improve product performance, many companies have increasingly strict requirements on oxygen, humidity, and particle size in the production process, so equipment such as vacuum leak detection, vacuum welding, and vacuum degassing have been widely used. Generally speaking, the mass production of products requires these devices to work at a faster pace, requiring frequent opening and closing of vacuum chambers. In these vacuum equipment, the vacuum chamber often adopts a horizontal or vertical structure, and the door opening method of the vacuum chamber is usually in the form of a side-hung door or an upturned door. This type of door opening is provided with a shaft on the side of the chamber door cover , the other side is equipped with a manual or pneumatic handle, and t...
