Anti-falling structure of upper folding door

Abstract

The invention discloses an anti-falling structure of an upper folding door. The structure comprises an upper door plate, a drawstring fixer, guide rails, guide wheels, a flexible driving structure anda stop structure. The drawstring fixer is arranged on the upper door plate, the guide rails are located on the two sides of the upper door plate, the guide wheels are matched with the guide rails, the flexible driving structure comprises a rotary driver and a flexible shaft, the rotary driver is arranged on the upper door plate and connected with the drawstring fixer, and one end of the flexibleshaft is connected with the rotary driver; the stop structure comprises a rack and a stop box, the rack is arranged on the guide rails, the stop box is connected with the guide wheel and the other endof the flexible shaft, and a telescopic stop block is arranged on the stop box and can be matched with the rack to stop the stop box; when the rotary driver acts, the flexible shaft can be used for controlling the telescopic stop block to extend outwards and be matched with the rack. The safety problem that a door plate falls in the using process of the upper folding door can be effectively solved, and the using safety of the upper folding door can be improved.

Description

technical field [0001] The invention relates to the technical field of folding doors, in particular to an anti-falling structure of a folding door. Background technique [0002] Folding doors are suitable for large-span doorways, especially for buildings with no space on the upper part of the doorway and on both sides. It can be widely used in garages, hotels, villas or other large-span doorways. Folding doors are usually folded or unfolded by electric motors winding wire ropes or pull belts. Folding doors are of high quality. If the wire rope or pull belt breaks suddenly during use, the door panel of the folding door will slide down quickly. , and seal the door, it is not safe to use, so it is necessary to design a fall-proof structure that can prevent the door panel of the folding door from falling; in the prior art, the quality of the folding door is usually reduced by setting a balance counterweight , the balance counterweight component can reduce the force of the door ...

AI Technical Summary

Problems solved by technology

Folding doors are usually folded or unfolded by electric motors winding wire ropes or pull belts. Folding doors are of high quality. If the wire rope or pull belt breaks suddenly during use, the door panel of the folding door will slide down quickly. , and seal the door, it is not safe to use, so it is necessary to design a fall-proof structure that can prevent the door panel of the folding door from falling; in the prior art, the quality of the folding door is usually reduced by setting a balance counterweight , the balance counterweight component can reduce the force of the door panel on the steel wire rope or pull belt, thereby increasing the safety of use, for example, in the patent document with the patent number "CN201520235550.1" and the name "electric strut type top folding door" A balance counterweight component "balance weight" is provided, and the patent document with the patent number "201520216816.8" and the name "a bi-fold door" is provided with a balance counterweight component "balance hammer", but in actual application, the balance counterweight The components are suspended by wire ropes. If the wire rope connected to the balance weight part breaks, the wire rope or pull belt connected to the door panel will break and cause the door panel to fall. If the wire rope or pull belt connected to the door panel is broken, the door panel will pull the balance weight The rapid downward movement of heavy parts cannot play a stopping role, and there are still potential safety hazards in use; when the upper folding door falls, the lower door panel moves down rapidly. The technical solution of anti-falling, this kind of solution will fail when the lower door panel falls slowly, and it cannot better improve the safety in use
