a vent door

Abstract

The invention discloses a venting door, comprising a door frame and a door body, wherein the door frame is rotationally connected with the door body through a hinge, the middle part of the door body is provided with at least one secondary door, one side of the secondary door is rotationally connected with the door body through the hinge, the other side of the secondary door is connected with the door body through an explosion venting fastener, the door body is locked through a lock body, and the lock body is connected with the door body through the explosion venting fastener. According to the venting door disclosed by the invention, the door body is connected with the door frame through a vertical spindle to enable the open angle of the door body to be greater than 90 degrees, the door body can be flexibly opened, and pressure relief is facilitated; meanwhile, a lock catch is connected with the door body through the explosion venting fastener, at the moment of explosion, the lock catch falls off due to the impact force of the explosion, the door body is opened to release pressure, meanwhile, indoor people is conveniently to escape; in addition, the lock catch and door body as well as the vertical spindle are connected, so that the door frame, the door body and the lock catch form as whole, not only is the installation convenient, but also the connection with the building wall is reduced, hence the pulling to the building wall is reduced during the explosion process, and the damage to the building wall is lowered.

Description

technical field [0001] The invention relates to the technical field of explosion-proof safety, in particular to an explosion-venting door. Background technique [0002] Explosion venting door is a kind of door body that can be quickly self-opened at the moment of indoor explosion to quickly discharge the explosion pressure to the outside and reduce the impact of the explosion. It is mainly used in industrial buildings, research institutes, etc., and can effectively protect the lives of personnel. Safety, to ensure that the internal equipment of the building is intact, to ensure that the overall structure of the building is intact, free from the hazards of explosion shock waves, and at the same time prevent the explosion hazard from continuing. [0003] For example, Chinese patent CN205135323U discloses a kind of explosion venting door, which includes an explosion venting door body. The explosion venting door body includes two galvanized cold-rolled steel sheets and a firepro...

Problems solved by technology

[0005] However, the explosion vent doors disclosed in the above two utility model patents only have the function of timely pressure relief, and there is no structure for emergency escape. Although the pressure relief function can be achieved at the first time, it is not convenient for the evacuation of indoor personnel.
