Abstract

A novel open-close mechanism of a door is fixedly installed on a building or a device above an upper guiding rail through two pin shafts of the on-off door mechanism. A connection line of the two pin shafts above the upper guiding rail is parallel to the upper guiding rail and a lower guiding rail. Another two pin shafts are fixedly installed on the front face or the back face of the door, wherein a connection line of the two pin shaft installed on the door is parallel to the connection line of the two pin shafts installed above the upper guiding rail, and distances of the connection lines are equal. A spring steel wire or steel plate is composed of two identical spring steel wires or two identical steel plates. Two ends of each spring steel wire or steel plate are correspondingly connected with one of the pin shafts located above the guiding rails and with the pin shafts on the door in a hinged mode. The novel open-close mechanism of the door has the advantages of being simple in structure, relatively low in cost and quick in speed of on-off door.

Description

technical field [0001] The invention relates to a door opening and closing mechanism, in particular to a novel door opening and closing mechanism, which belongs to the technical field of door industry. Background technique [0002] At present, there are various types of mechanisms for opening and closing doors, such as: hydraulic cylinder or cylinder drive type, motor drive type through the corresponding mechanical transmission system; semi-mechanical, semi-manual or other types of drive types... , but all these existing door opening and closing mechanisms are generally all more complicated, cost is higher, and door opening and closing speed is slower. Contents of the invention [0003] The object of the present invention is to provide a novel door opening and closing mechanism, which has the advantages of simple structure, low cost and fast door opening and closing speed. [0004] The technical solution adopted by the present invention to achieve the above object is: a n...
