Split pillar and ventilation hood employing same

Abstract

The invention relates to a split pillar, comprising a pillar body that is axially extended and in profile shape. From the cross section of the profile, the pillar body includes a front wall portion, a rear wall portion, a left wall portion and a right wall portion; the front and rear wall portions and the left and right wall portions enclose at least one first chamber that is hollow, the front and rear wall portions are provided with front and rear through holes arranged along the cross section, and the front and rear through holes run through the first chambers and are in front-rear correspondence; a pillar cover releasably covers the front of the front wall portion, the pillar cover is axially extended and in profile shape, a second chamber is formed between the pillar cover and the pillar body so that the front through holes run through both the first chambers and the second chamber, and the pillar cover is provided with a mounting hole that runs through the second chambers. Therefore, the split pillar has ideal supporting strength, can act as a support pillar, and can also act as a receptacle for storage pipes, electrical appliances and the like.

Description

technical field [0001] The invention relates to a split column, which can not only play a supporting role, but also store various functional pipes. The split column can be used to assemble various furniture items, such as wardrobes, bookcases and the like. Among many applications, the present invention proposes a fume hood using the split column. Background technique [0002] In the process of conducting experiments, especially chemical experiments, not only will a large number of flammable, explosive and corrosive substances be applied, but also a large amount of harmful gases will be produced. In order to ensure the safety of the experimenters, most of the experimental operations must be carried out in a fume hood. The fume hood can prevent the pollutants used or generated during the experiment from spreading in a large area in the laboratory and discharge the polluted gas outside the laboratory through its own exhaust system. The fume hood has become an important safet...

AI Technical Summary

Problems solved by technology

However, in a specific application scenario, the left and right side walls or the top wall are not facing the experimenter, if the control panel, display panel, etc. are installed on the left and right side walls or the top wall It is not convenient for experimenters to operate and observe

However, if the control panel, display panel and other electrical components are installed on a pair of front columns located on the front of the fume hood, how to install the control panel, display panel and other electrical components, as well as arranging power supply pipelines for them is also a need for further consideration. question
