Description

Green environmental test cabinet

Technical field

The invention relates to a laboratory cabinet, and more particularly to a green environmental protection test cabinet.

Background technique

The experimental cabinet is the key equipment of the modern laboratory. It is more stressful on the design of the door structure of the laboratory cabinet. Because the laboratory equipment has many individual design requirements in the process of engineering construction, only the materials such as wood and steel can be used. The semi-finished products are transported to the construction site for uniform construction. The installation and transportation are inconvenient, the cost is high, and the equipment produced is not resistant to acid and alkali, moisture, water, water, rust and rot. The cabinets of the existing laboratory test cabinets are mostly assembled by screws or bonding. There are many parts and it is troublesome to disassemble. In the laboratory environment with strong acid and alkali and moisture, the screws will be short-term. It will be severely corroded and rusted, resulting in unsightly appearance of the door panels of the laboratory cabinet. The existing test cabinets are generally bonded or screwed to adjacent cabinets. The bonding method is not stable. The adjacent cabinets are fixed by screws, which are not resistant to acid and alkali, easy to rust, and at the same time, during the handling process. In the case of inconvenient disassembly and assembly, it is easy to cause damage to the connection between the cabinet and the cabinet.

Also, the common laboratory cabinets are equipped with drawers that are pulled or pushed through the steel rail assembly. Steel rail assemblies are typically located on the side or bottom of the left and right side panels of the drawer. The slide rail assembly is disposed on the side of the left and right side panels of the drawer. When the load is too large, the screw is loosened, the rail is rusted and stuck, and the slide rail is disposed at the bottom of the left and right side panels of the drawer. When the load is too large, the same It will easily lead to the rusting deformation of the slide rails, and the drawers of these structures are often lightly loaded, rust-free and durable, and need further improvement. The existing laboratory cabinet drawers are driven by screws to fix the steel rails on both sides of the drawer to drive the drawers, and the slide rails are made of metal. The metal rails and screws are easy to rust and corrode, and are easily damaged over time. Can not play the role of the rail rolling.
