Description

Technical Field

[0001] The utility model belongs to the field of one-way revolving doors, and particularly relates to an electric one-way revolving door. Background Art

[0002] In crowded areas such as public buildings, commercial centers, and large office spaces, revolving doors are usually used as access channels to achieve effective management and control of the flow of people. Revolving doors can not only isolate the external environment, maintain indoor temperature and cleanliness, but also play a role in security prevention to a certain extent. Traditional revolving doors are mostly designed for two-way passage, that is, people are allowed to freely enter and exit in both directions. However, in certain specific occasions, such as railway stations, revolving doors also need to have the function of one-way passage to prevent passengers from passing items without security inspection.

[0003] Currently, the driving mechanism of one-way revolving doors mainly includes a motor, a speed reducer, and a gear transmission structure. The motor drives the revolving door body to rotate through the speed reducer and the gear transmission structure. When there is a power failure or other situations where pedestrians need to push the revolving door body, due to the limitation of the transmission ratio of the transmission structure, pedestrians need to apply a very large force to the revolving door body to make it rotate, which causes great inconvenience to pedestrians. At the same time, since the gears inside the speed reducer are relatively small, when pedestrians push the revolving door body, the power is transmitted to the speed reducer, which is likely to cause damage to the internal gears. This not only increases the maintenance cost but also affects the service life of the revolving door.

[0004] Therefore, based on the above situations in the prior art, this application has been further designed and improved. Content of the Utility Model
