A multifunctional double-layer composite hatch with self-locking and anti-locking devices

Abstract

The invention provides a multifunctional double-layer composite cabin door with self locking and reverse locking devices. The multifunctional double-layer composite cabin door comprises a hinge, a pin shaft assembly, an outer door assembly, an inner door assembly, an inner turntable, an outer turntable, a left door bolt moving element assembly, a right door bolt moving element assembly, a gear transmission device assembly, a door frame assembly, a self locking device assembly and a reverse locking device assembly, wherein a support frame table arranged in the self locking device assembly is fixedly arranged between the inner and outer door assemblies, and supports the first guide rod, the first guide rod passes through the left door bolt moving element assembly, the two ends of the first guide rod are respectively connected with a self locking press button and a locking sheet, a rotating shaft arranged in the reverse locking device assembly is arranged on a fixing block arranged on an inner door plate, the two ends of the rotating shaft are respectively connected with a rotating plate and a rotating handle, and stop blocks and screw bolts are respectively arranged above the two sides of the rotating plate. When the cabin door is opened, a self locking press button is pressed through the self locking device, door bolt heads are enabled to be respectively locked in the door without extending out, the abrasion on the cabin wall around the cabin door is prevented, and in addition, the reverse locking on the cabin door at the side surface of the door can also be realized.

Description

technical field [0001] The invention relates to a multifunctional double-layer composite hatch, in particular to a multifunctional double-layer composite hatch with self-locking and anti-locking devices. Background technique [0002] At present, China's urbanization process is getting faster and faster, and high-rise buildings are increasing day by day. With the development of the city, the fire hazards of high-rise buildings are gradually exposed. For high-rise building fires, external rescue and fire-fighting operations cannot be carried out, resulting in heavy losses of personnel and property. Based on the above situation, more and more people start Configure life-saving equipment for disaster emergency response. With the promotion and use of life-saving equipment such as safety cabins, safes and other disaster emergency equipment, it provides strong protection for our life safety, property safety, etc., and the hatch, as an indispensable part of the safety cabin, is a s...
