Multistage telescopic universal exhaust hood for laboratory

Abstract

The invention discloses a multi-stage telescopic universal exhaust hood for a laboratory, which is used for a laboratory. The multi-stage telescopic universal exhaust hood for the laboratory comprises a telescopic mechanism, a rotating ring, a multi-stage direction-adjusting mechanism and an exhaust hood body, wherein a driving motor is mounted at the top of the telescopic mechanism, an air guide hole is formed in one side of the top of the telescopic mechanism, the telescopic mechanism is communicated with an exhaust pipeline in the laboratory through the air guide hole, the rotating ring is rotationally mounted at the bottom of the telescopic mechanism, the telescopic mechanism is of a circular column structure or a square column structure, the other end of the rotating ring is fixedly connected with the multi-stage direction-adjusting mechanism, and the multi-stage direction-adjusting mechanism is fixedly connected with the exhaust hood body. The overall height of the exhaust hood is adjusted through the telescopic mechanism, the actual use position of the exhaust hood is flexibly adjusted through the multi-stage direction-adjusting mechanism, use is flexible, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of laboratory appliances, in particular to a laboratory multi-stage telescopic universal fume exhaust hood. Background technique [0002] Existing infectious disease specialist or large hospital PCR laboratories have limited testing capacity and need to be expanded; for secondary hospitals or township and community level hospitals that do not have such laboratories, new laboratories need to be built; for newly built temporary hospitals, new laboratories are required; The experiment needs to be equipped with a fume exhaust hood. [0003] However, the existing exhaust hood is integrally formed, and the relative directions of the air inlet and the exhaust port are fixed. During installation and subsequent use, it is difficult to adjust the relative direction of the air inlet and the exhaust port, and the exhaust hood cannot Flexible adjustments lead to higher limitations. [0004] Therefore, there is an urgen...
