Springdoor rotating shaft type vertical hinged door toppling safety protection device

Abstract

The invention discloses a springdoor rotating shaft type vertical hinged door toppling safety protection device, and belongs to the field of springdoors. The springdoor rotating shaft type vertical hinged door toppling safety protection device comprises a fixed clamp, a movable clamp and a toppling safety protection assembly. The toppling safety protection assembly comprises first fixing blocks, second fixing blocks, rotating shafts, a high-strength protection steel cable, a steel cable pressing head and a locking head, the first fixing blocks and the second fixing blocks are correspondingly and fixedly installed between the fixed clamp and the movable clamp through fasteners, the rotating shafts are installed between the first fixing blocks, a first through groove hole allowing the rotating shaft to be movably inserted is formed between the second fixing blocks, through holes are formed between the rotating shafts in a penetrating mode, and the high-strength protection steel cable is movably arranged between the through holes in a penetrating mode. The steel cable pressing head is fixedly arranged at one end, close to the first fixing blocks, of the high-strength protection steel cable, and the locking head is fixedly arranged at the other end of the steel cable pressing head. The springdoor falling down and falling off can be stably and safely pulled and limited, the use safety of the springdoor is improved, and the personal safety of a user is guaranteed.

Description

technical field [0001] The invention relates to the field of pop-up doors, in particular to a safety protection device for dumping of a swing-type swing door of a pop-up door. Background technique [0002] The floor bounce door is a form of side-hung door that can be opened in both directions from inside and outside, which uses an underground spring hydraulic piston damping device to provide rotation and positioning damping for the rotation and closing of the door shaft. Because of its simple structure, it can be opened freely inside and outside, and is widely used Various entrances and exits of buildings. Due to various reasons such as material quality, assembly quality, and improper use and maintenance of the existing ground bomb doors, safety accidents occur, and even personal casualties are caused. Analysis of many accident causes, small size of the door leaf processing, settlement of the lower floor spring, insufficient strength and rigidity of the door frame or door l...

Problems solved by technology

Due to various reasons such as material quality, assembly quality, and improper use and maintenance of the existing ground bomb doors, safety accidents occur, and even personal casualties are caused.

Analysis of many accident causes, small size of the door leaf processing, settlement of the lower floor spring, insufficient strength and rigidity of the door frame or door leaf material, etc. lead to the separation of the top shaft of the door frame from the shaft hole of the door body, and the door body toppling after the upper limit of the door body fails is the most common problem , in order to ensure the safety of use, the present invention discloses a safety protection device for toppling over of the swing door of the swing door
