Automatic revolving door

Abstract

The invention provides an automatic revolving door, comprising a central door post, and glass doors uniformly distributed on the periphery of the central door post. Each glass door is built on a same cylindrical base. The cylindrical base is divided into a plurality of fan-shaped regions by the glass doors. Each fan-shaped region comprises a fan-shaped groove and a fan-shaped panel supported by a supporting spring in the fan-shaped groove. An active permanent magnet is vertically fixed under the fan-shaped panel. The cylindrical base is built on a foundation and can freely rotate around the axis of the central door post. The foundation is provided with a round pit under the cylindrical base. The round pit is internally vertically fixed with passive permanent magnets, and like poles of the passive permanent magnet and the active permanent magnet repel on a vertical direction. The number of the passive permanent magnets is two and the passive permanent magnets are symmetric to the wall where a door frame is in, and the permanent magnets are on a vertical median section of the door frame. The automatic revolving door can automatically rotate after a person enters the door, and the door does not consume electric energy. The door provides convenience for access, and saves energy and is environmentally friendly.

Description

technical field [0001] The present invention relates to the field of building doors, in particular, to a revolving door. Background technique [0002] Revolving doors are mainly used in the main halls of various large buildings; as far as the current revolving doors are concerned, most of them need to be pushed manually, which is less convenient; a few high-end revolving doors are equipped with motors, which usually keep rotating continuously, which makes the energy Waste is more serious. SUMMARY OF THE INVENTION [0003] In view of the above problems, the purpose of the present invention is to provide an automatic revolving door, which can automatically rotate after the human body enters the door, and does not consume electricity, which is convenient for entry and exit, and is energy-saving and environmentally friendly. [0004] The technical solution adopted by the present invention to achieve the technical purpose is as follows: the automatic revolving door include...
