Mechanical principle based automatic door closer and use method thereof

Abstract

The invention discloses a mechanical principle based automatic door closer and a use method thereof. The mechanical principle based automatic door closer comprises a workbench; the workbench is internally provided with a door entering space, the front end wall and the back end wall of which communicate with an external space; the lower end wall of the door entering space is internally provided with a transmission space; the right end wall of the transmission space is internally provided with a driven space; the left end wall of the transmission space is internally provided with a hydraulic space; the left end wall of the hydraulic space is internally provided with a sliding door space, the left end wall of which communicates with the door entering space; the lower end wall of the hydraulicspace is internally provided with a hydraulic pipeline which communicates with the hydraulic space arranged at the two ends of a partition plate; and the lower end wall, at the upper end of a cam, ofthe hydraulic pipeline is internally provided with a sliding space. The mechanical principle based automatic door closer provided by the invention is simple in mechanism and convenient to operate, can be opened in one way only, can effectively prevent an entrant from repeatedly entering from the sliding door, effectively maintains an entering and exiting order, can reopening a door according to the weight of a person, can automatically deadlock the door when a child enters the door to avoid the child from entering and has very high safety.

Description

technical field [0001] The invention relates to the field of automatic safety one-way doors, in particular to an automatic door closer based on a mechanical principle and a method for using the same. Background technique [0002] At present, with the advancement of science and technology and the development of society, there are more and more types of door closers. Most of the existing doors are two-way doors. There are few types of one-way doors and single functions. Using one-way doors can effectively maintain The order of entry and exit has good practicability in real life. Most of the existing one-way doors do not have the effect of automatic door closing. One-way doors in many dangerous places cannot restrict children from entering and may cause safety accidents. Contents of the invention [0003] The object of the present invention is to provide an automatic door closer based on a mechanical principle and its usage method, so as to solve the problems raised in the ab...
