It is generally used in hospitals, food factories, industrial plants and other places with high requirements for sound insulation, heat insulation and airtightness. An airtight door can form an isolated space, so that a certain negative pressure is formed indoors, that is, the indoor pressure is lower than the outdoor pressure, and the outdoor pressure acts on the door body, which tightly closes the door body to ensure that the indoor air purification does not leak out. It can generally be used at the entrance of an operating room or a semi-chemical room. The existing airtight door closes or opens the door frame by sliding, and a sealing strip is provided between the door frame and the airtight door to seal the joint so that the airtight door can be effectively sealed. However, due to the long-term use of the airtight door, the connection sealing is prone to wear, which makes the sealing easily affected, affecting its protection of the indoor airtight seal. At the same time, when the airtight door is not locked, it only needs a small thrust to slide open and close, so it is easy to be opened by external force when it is not locked, thereby affecting the use of the airtight door.
