Description
Technical Field
[0001] The utility model relates to the technical field of automatic revolving doors, and in particular to an automatic revolving door with a reverse protection structure. Background Art
[0002] Automatic revolving door is a modern entrance device, so it is widely used in commercial buildings, hotels, banks, hospitals and other places for its convenience. Automatic revolving door keeps regular rotation during use. Passengers need to choose the right time to enter from the entrance, then walk along the rotation of the revolving door, and choose the right time to go out from the exit at the other end. If the entry and exit time is wrong, the passers-by will be clamped between the revolving door body and the arc partition. Most common automatic revolving doors are not equipped with corresponding reversal protection structures, and the revolving door body cannot be reversed when clamping the passers-by, so as to get rid of the clamping of the passers-by, which will cause certain clamping problems to the passers-by. This is a painful injury to the passers-by themselves, and different parts of the body that are clamped may also face different subsequent problems.
[0003] Secondly, if the revolving door injures passers-by, the unit using the door will face relevant joint liability and may face rectification and punishment from relevant units, as well as accusations and claims from the injured persons, which will cause the unit using the door to face certain expenses and potential image impact.
