Problems solved by technology
[0002] At present, large-scale factory buildings need to set up a certain number of safety door passages according to fire protection requirements, but factories often reduce guards, and management is simple. Often only one safety door passage is left, and all other safety door passages are locked. At the exit of the safety door, because the safety door is locked, there is no way to escape. This situation is not only caused by problems in the management level, but also in the design of the door.

The invention discloses an elastic self-unlocking long lever arm safety escape door for a factory, which comprises rotary door leaves, door spindles, a door catch and elastic self-unlocking mechanisms, wherein a movable baffle, a spring fixed arm and a compression spring are arranged on each elastic unlocking mechanism; one end of each spring fixed arm is fixedly connected with the corresponding movable baffle; the other end of each spring fixed arm is fixedly connected with the corresponding compression spring; a lock bar, an upper slide rail and a lower slide rail are arranged on each movable baffle. Compared with the prior art, the flexible self-unlocking long lever arm safety escape door adopts the flexible long lever arm unlocking design, is simple in structure, dispenses with a doorkeeper for guarding all the time, can be unlocked quickly, facilitates collective escape of workers in the factory, and is lower in cost, stable in structure, simple to use and convenient to maintain.
Description
technical field [0001] The invention is a fast and safe escape door designed for the safety door of the factory building which is locked and cannot be opened in time when a fire occurs in the factory building and the workers cannot escape quickly. It belongs to the technical field of fire safety. Background technique [0002] At present, large-scale factory buildings need to set up a certain number of safety door passages according to fire protection requirements, but factories often reduce guards, and management is simple. Often only one safety door passage is left, and all other safety door passages are locked. At the exit of the safety door, because the safety door is locked, there is no way to escape. The emergence of this situation is not only a problem at the management level, but also a defect in the design of the door. Contents of the invention [0003] The technical problem to be solved by the present invention is to invent an elastic self-unlocking long-arm fact...
