Ventilation hood capable of being opened in four sides

Abstract

The invention relates to a ventilation hood capable of being opened in four sides. The ventilation hood comprises middle bearing mechanisms and middle upper supporting plates, side glass frames are installed on the outer walls of the bottoms of the middle bearing mechanisms, side bearing mechanisms are fixed to the side ends of the side glass frames, and side door handles are installed at the topsbetween the middle bearing mechanisms and the side bearing mechanisms; penetrating holes run through the interiors of the side door handles, the middle upper supporting plates are installed at the inner sides of the bottoms of the middle bearing mechanisms, cabinets are fixed to the tops of the middle upper supporting plates, cabinet middle holes run through the middles of the cabinets, and cabinet side holes are formed in the sides, away from the cabinet middle holes, of the inner walls of the cabinets. According to the ventilation hood capable of being opened in four sides, the side ends ofthe ventilation hood can be supported through side columns, that is to say, the side columns are uniformly distributed at the four corners of the ventilation hood body, and connected with the side glass frames through middle front columns. The overall assembly effect of the ventilation hood body is better, all parts are more firmly connected, and the safety performance of the ventilation hood during use is improved.

Description

technical field [0001] The invention relates to the technical field of ventilation hoods, in particular to a ventilation hood capable of opening doors on four sides. Background technique [0002] Cabinet-type exhaust hoods are similar to airtight hoods. Small parts painting cabinets and chemical laboratory ventilation hoods are typical structures of cabinet-type exhaust hoods. Large-scale chamber-type ventilation hoods have one side completely open, and operators work in the cabinet. For large-scale painting, powder bagging, etc., the working opening of the ventilation hood has a great influence on the airflow distribution in the cabinet, and the airflow distribution directly affects the working effect of the cabinet type exhaust hood. [0003] Since the device body is not equipped with a good linkage structure, that is, there is no good linkage sliding fit structure between each node, so that the device body cannot perform flexible sliding adjustment operations, that is, it...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a ventilation hood that can open from all sides to solve the problem that the device body proposed in the background technology is not equipped with a better linkage structure, that is, there is no better linkage sliding fit between each node. structure, resulting in the inability of the device body to perform flexible sliding adjustment operations, that is, the inability to perform push-pull and other manipulations, which is inconvenient to use, and at the same time cannot improve the safety performance of the device body during use, and is not equipped with multiple sets of intermediate bearings. mechanism, which makes it inconvenient to connect and use with each node, and at the same time improve the ventilation performance of the device body, there is also a poor situation
