Double-person ultra-clean workbench for laboratory

Abstract

The invention is applicable to the technical field of laboratory equipment, and provides a double-person ultra-clean workbench for a laboratory. The double-person ultra-clean workbench comprises a workbench surface, wherein a top cover is arranged on the workbench surface, and an ultraviolet lamp and a fire extinguishing structure are arranged below the top cover; the fire extinguishing structure comprises a translation assembly, a lifting assembly and a fire extinguishing assembly; the translation assembly comprises a rotating shaft, a moving block is in threaded connection with the rotating shaft in a sleeving mode, the moving block is connected with a first lifting piece and a second lifting piece through a bearing plate, the lower portion of the first lifting piece and the lower portion of the second lifting piece are rotationally connected with the fire extinguishing assembly, the fire extinguishing assembly comprises a storage cavity and an accommodating cavity, and the height from the accommodating cavity to the workbench surface is matched with the height which can be reached by the two hands of an experimenter. Therefore, after the two hands of the experimenter are on fire, the two hands can be quickly extinguished within 2-3 s, so that the experimenter is prevented from being scalded or burnt, and the safety of the experiment is improved.

Description

technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to a laboratory double-person ultra-clean workbench. Background technique [0002] The ultra-clean workbench is designed to meet the needs of cleanliness and sterility in the local work area in the fields of modern industry, optoelectronic industry, biopharmaceuticals, and scientific research experiments. It is divided into single-person workbench and double-person workbench. The ultra-clean workbench generally includes a worktable, an outer cover, a transparent window, and an ultraviolet germicidal lamp. The transparent window is provided with through holes for extending hands. [0003] Since the ultra-clean workbench can only protect the reagents and medicines operated in the workbench from contamination, the experimenter needs to put alcohol lamps, alcohol spray cans, petri dishes, culture bottles, etc. Centrifuge tubes, sterile gloves and other required experimenta...

Problems solved by technology

[0007] Publication No. CN105413781A patent discloses a fireproof ultra-clean bench, patent publication CN208260809U discloses a biotechnology ultra-clean bench, the ultra-clean benches of the above two patents are equipped with fire prevention devices, but Its fire prevention device is only used for the fire extinguishing work after the whole ultra-clean bench is on fire, not for protecting the experimenters whose hands are on fire

[0008] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
