Rapidly opened and closed electric folding door

Abstract

The invention discloses a rapidly opened and closed electric folding door. The door mainly comprises a door frame, a door leaf, a push and pull small door leaf, a rotating small door leaf, a motor, alarge gear, two small gears engaged with the large gear and two slider-crank mechanisms, a rotating shaft is fixedly connected with a main motor output shaft, two cranks are hinged to the upper end faces of the two small gears engaged with the large gear correspondingly, when the large gear rotates, the push and pull rotating leaf and a main rotating leaf rotate in the same direction, the small push and pull door is drawn back under the effect of tension of a rack while rotation is carried out, a rack on the other side enables a gear shaft to rotate under the effect of a push rod, a sub rotating leaf can be driven to rotate to be close to a main rotating leaf while rotation is carried out, when a lifting motor is started, a rotating shaft is lifted upwards under the effect of a screw, a main motor is started, the push and pull rotating leaf and the main rotating leaf cannot rotate, the small push and pull door and the sub rotating leaf still can do push and pull and rotation action, and the door has the advantages of being rapid in opening and closing, diverse in function and capable of meeting different use needs.

Description

technical field [0001] The invention relates to the field of door and window manufacturing, in particular to a fast opening and closing electric folding door. Background technique [0002] With the development of industrial society, the degree of industrialization of modern factories is getting higher and higher. This is not only reflected in the highly automated production lines, but also in all aspects of the factory. The door of the factory building is a good example. In normal production During the process, not only workers will pass through the factory gate, but also vehicles for transporting materials will pass by. In order to ensure production efficiency, a fast-opening and closing factory gate is required. At present, lift doors and rolling doors are mostly used in factories. The door has the disadvantage of slow movement, so the present invention provides a fast opening and closing electric folding door, which can realize different opening modes according to the two...
