[0002] Stacking door is a common industrial door, which has the characteristics of fast opening and closing and small space occupation. However, due to its complex structure, it is easy to cause collision accidents.

[0003] The existing patent (Announcement No.: CN217741609U) proposes an anti-collision structure for a magnetic stacking door. The utility model solves the problem that the distance between the two sets of baffles in the existing anti-collision structure for magnetic stacking doors is fixed and cannot be adjusted in time according to the width of the transport vehicle. The utility model uses a driving motor, a push rod, a bump and a support plate. When the driving motor drives the push rod to rotate, the push rod uses the bump engaged with it to push the support plate inward, and the support plate drives the baffle plate to move, thereby completing the position adjustment of the baffle plate, allowing the baffle plate to adjust the distance between the two sets of baffle plates according to the size of the vehicle, ensuring that the baffle plate can block all types of vehicles and prevent the transport vehicle from passing through the middle area of ​​the baffle plate and approaching the main body of the stacking door.

[0004] The above device has a certain anti-collision effect, but the effect is not good enough. The baffle is easily damaged and cannot prevent forklifts of different heights from colliding. Therefore, we propose an anti-collision structure for the stacking door. Utility Model Content
