[0002] A laboratory is usually a specific place in a scientific research institution, university or industrial enterprise for scientific research, experiments and testing. In the laboratory, researchers can conduct experiments in chemistry, biology, physics and other fields to solve problems, verify theories or develop new technologies. The laboratory is usually equipped with a variety of instruments and equipment to support scientific research and experiments. In the laboratory, a variety of gases are usually used for experiments. However, in real life, we usually know that gases are usually stored in gas cylinders.

[0003] In real life, we usually know that the gas cylinders in the laboratory are usually placed on a rack and moved to a designated position for use when in use. However, due to the large number of people in the laboratory, especially for some more complicated experiments, multiple people are usually required to assist in completing them. However, in the process of the experimenters walking, the gas cylinders may be knocked down. However, in the existing technology, there is usually no shock and explosion proof function for the gas cylinders. As a result, the gas cylinders will explode due to the large vibration after being knocked down, which brings great safety hazards to the experimenters in the laboratory. Utility Model Content

[0011] As mentioned above, the upper surfaces of the two protective doors are respectively fixedly connected with a fixed block 1 and a fixed block 2, and the fixed block 1 and the fixed block 2 are both passivated. By passivating the fixed block 1 and the fixed block 2, it can provide certain protection for people and prevent people from being scratched when opening the protective door.
