Abstract

The invention belongs to the technical field of civil air defense engineering, in particular to a flexible recoil type impact-resistant anti-explosion door. The flexible recoil type impact-resistant anti-explosion door comprises a door frame, door bodies, a movable plate, a spring, a slide block, a chute, a flexible plate and a connecting shaft. Impact waves generated by explosion are acted to thedoor bodies, so that the door bodies deviates, and the gap between the two door bodies is increased. As the flexible plate has a flexible characteristic, the flexible plate deforms when the gap between the two door bodies is increased. A part of impact energy is absorbed by deformation of the flexible plate, and a movable plate and the door bodies are kept in parallel with deformation of the flexible plate, so that the movable plate can move along the direction of a door plank. When the movable plate moves to compress a spring, the impact waves are transferred to the spring, and energy of theimpact waves is absorbed by deformation of the spring, so that deformation of the door bodies subjected to impact during rigid connection of the door bodies is prevented. It is convenient for the anti-explosion door to open after being subjected to impact, so that a condition that staff is trapped due to deformation of the anti-explosion door is further avoided.

Description

technical field [0001] The invention belongs to the technical field of civil air defense engineering, in particular to a flexible recoil type impact-resistant explosion-proof door. Background technique [0002] The explosion-proof door is to resist the accidental explosion of the external device of the industrial building, protect the safety of personnel and the internal equipment of the industrial building, and not be harmed by the explosion shock wave; effectively prevent the continuation of the explosion hazard. It is made of special industrial steel plates according to strictly set mechanical data, and equipped with high-performance hardware accessories, which is more practical and beautiful to use. Guarantee the safety of life and property. Explosion-proof doors are also called: anti-explosion doors; explosion-proof doors should be arranged in the combustion chamber, furnace outlet, economizer flue, flue in front of the induced draft fan, horizontal flue at the rear of...
