Abstract

The invention relates to a ventilation cabinet, and relates to the technical field of laboratory ventilation equipment. The ventilation cabinet comprises a workbench, a left side plate, a right side plate, a wind cover, a top plate, a cabinet body, a rear back plate and a protection door. A cavity is defined by the left side plate, the right side plate, the top plate, the workbench, the protectiondoor and the rear back plate. The wind cover is fixed to the top plate, and the cabinet body is fixedly arranged at the bottom of the workbench face. A transmission synchronous assembly is arranged on the ventilation cabinet and comprises two first synchronous gears located at the upper end of the right side plate, a first synchronous belt wound around the two first synchronous gears, two secondsynchronous gears located at the upper end of the left side plate, a second synchronous belt wound around the two second synchronous gears, and a balance weight block fixedly connected with the firstsynchronous belt and the second synchronous belt. The ventilation cabinet has the effect that the protection door ascends and descends more smoothly, stably and lightly.

Description

technical field [0001] The invention relates to the technical field of laboratory ventilation equipment, in particular to a fume hood. Background technique [0002] The existing chemical experiment process basically uses an open experimental bench, and some toxic and harmful substances are likely to be produced during the chemical experiment. The existing experimental bench cannot be well protected, and the long-term operation of the experiment will damage the body Health hazard. [0003] The Chinese patent with the publication number CN105921479A discloses a fume hood comprising a left side panel, a right side panel, an exhaust fan, a baffle plate, a storage box, a workbench, a glass door and a deflector, a left side panel and a right side panel They are respectively installed at both ends of the workbench, and the baffle is installed between the left side panel and the right side panel. The two sides of the baffle are respectively equipped with glass doors and deflectors....
