The drop-type double-leaf protective closed door is characterized by no threshold on the ground, which is convenient for people or vehicles to pass. When it is working, it needs to use a drive component to drive the lifting and closing of the protective door, but it still has the following disadvantages in actual use:

[0003] When the driving assembly of the drop-type protective door is working, the protective door is directly installed and driven to rise and fall through the driving structure. During the lifting process, it is easy to rise and fall in the groove that restricts it. When lifting, it is easy to cause the lifting structure to deviate due to the lifting, affecting the stability of the driving lifting;

[0004] When the driving assembly of the drop-type protective door is working, the driving structure is directly used to drive the lifting. The driving structure and the sliding structure of the protective door are installed together. During the sliding process, the vibration of the driving assembly is transmitted to the protective door, which can easily cause the lifting and shaking of the protective door, affecting the working stability.
