[0002] Laboratory fume hoods are common equipment in laboratories, which are used to remove harmful gases and vapors generated during experimental operations and ensure the safety of experimenters. As an important component of the fume hood, the fume hood window plays a great role. The fume hood window can be adjusted up and down at will, which is convenient for experimenters to adjust according to actual needs and ensure the smooth progress of experimental operations. This design also makes it convenient to lower the window to the lowest operating height when the experiment does not require hands-on operation, so as to effectively remove harmful gases, prevent leakage, and reduce energy consumption. However, the existing laboratory fume hood windows still have shortcomings. First, when the synchronous belt or steel wire connecting the window and the counterweight of the existing laboratory fume hood suddenly breaks, the mobile window will fall rapidly and hit the operator or instruments and equipment, and the equipment is not safe enough. Secondly, there are high requirements for the simplicity of the structure to prevent the window from falling, so that it is easy to maintain and improve the user experience. Therefore, it is necessary to design a laboratory fume hood window anti-fall system. Summary of the invention

[0005] As a further technical solution of the present invention, a debugging process hole is opened on the anti-falling baffle, and a clamp is provided on the anti-falling baffle.

[0006] As a further technical solution of the present invention, a connecting round pin is fixedly connected to the anti-fall baffle, one end of a tension spring is fixedly connected to the connecting round pin, and the other end of the tension spring is fixedly connected to a fixing column.

[0007] As a further technical solution of the present invention, the fixing column is fixedly connected to the anti-fall main structure component, and the anti-fall main structure component is fixedly connected with a connecting bolt.

[0008] As a further technical solution of the present invention, the connecting bolt is fixedly connected to the movable window, the movable window is slidably connected to the chassis, and an anti-falling rack is fixedly connected to the chassis.

[0011] The laboratory fume hood window anti-falling system provided by the present invention has the advantages that the anti-falling main structural part is fixed to the chassis by connecting bolts, the movable window is provided with movable support by a synchronous belt, the anti-falling rack is symmetrically installed on the chassis, and the anti-falling main structural part is symmetrically installed on the movable window, the equipment is debugged and installed through the debugging process hole, and the screws are screwed on during the installation and debugging process to prevent the anti-falling baffle from popping out and affecting the installation of the movable window. After the installation is completed, the screws in the debugging process hole are unscrewed before the equipment is used to turn on the anti-falling function. When the synchronous belt breaks accidentally, the movable window and the anti-falling main structural part fixed thereon fall on the chassis, and the synchronous belt releases the connection with the hook at this time. The anti-fall baffle is moved around the positioning pin until the clamp is stuck on the anti-fall rack and stops, and at this time the limit pin moves to the other side of the limit hole, and the anti-fall baffle is further limited and fixed, and the clamp is connected to the anti-fall rack through the clamp, so that the anti-fall baffle, the anti-fall main structure and the movable window stop falling, and the movable window of the laboratory fume hood is prevented from falling rapidly and hitting the operator or instruments when the synchronous belt or steel wire connecting the movable window and the counterweight of the laboratory fume hood suddenly breaks, thereby improving the safety of equipment use; at the same time, the equipment has a relatively simple structure, is easy to maintain, and improves the user experience.
