Description

Technical Field

[0001] The utility model relates to a laboratory table cabinet, in particular to an exhaust-resistant and corrosion-resistant laboratory table cabinet, belonging to the technical field of laboratory table cabinets. Background Art

[0002] Laboratory cabinets are indispensable items in laboratories. Most experiments need to be carried out on chemical experiment cabinets. With the development of science and technology, laboratory cabinets are not only used for chemical experiments, but also for storing objects. Different test cabinets have different functions. However, in order to keep the stored items under ventilation, most laboratory cabinets have exhaust functions.

[0003] When exhausting air into the laboratory cabinet, in order to prevent dust in the outside air from entering the laboratory cabinet, a dustproof plate is usually installed at the vent. However, during long-term use, the dustproof plate will be blocked, thereby affecting the ventilation effect. Therefore, the staff needs to regularly remove it for deep cleaning. However, in the existing technology, the dustproof plate is usually installed with multiple sets of screws, which makes it time-consuming and laborious for people to disassemble, thereby reducing people's cleaning efficiency of the dustproof plate. In addition, when the laboratory cabinet is used for experiments, water stains may splash on the screws, causing the screws to rust, making it difficult for people to disassemble.

[0010] Furthermore, the inner wall of the laboratory cabinet body is provided with a symmetrical dustproof mesh plate, and the fixed seat 1 is fixedly connected to the outer surface of the dustproof mesh plate. By separating the limit column from the limit cylinder, the limit on the limit cylinder can be released, and then the limit on the fixed seat 1 can be released, thereby releasing the limit on the dustproof mesh plate.

When installing the dustproof mesh panel, the fixing seat 2 must be clamped on the inner wall of the fixing groove, and the fixing groove can play a role of positioning and supporting the fixing seat 2. The dustproof mesh panel can block dust, and an exhaust fan corresponding to the dustproof mesh panel is installed inside the laboratory cabinet body.
