Abstract
A mechanical synchronous shrinkage door belongs to the field of machine electricity, and is applied in emergent escape when doors are deadly stuck under the conditions, such as daily house theft prevention, earthquake, fire and the like. The door adopts a pure mechanical structure to guarantee normal, stable and reliable operation in disaster emergency. A one-key trigger is additionally provided to leave out a larger space in a door body when enabling the door body to has a shrinkage function, so that reinforcement of the door body and other operations are conveniently implemented. The door guarantees the shape and the theft prevention function of the normal door body, and has one added function of dead locking prevention compared with existing security doors in the market. The door is suitable for the emergent escape under the conditions, such as daily house theft prevention, earthquake, fire and the like, and has a larger actual application space.
Description
Technical field
The present invention relates to a kind of mechanical type synchronous door, the upper and lower and left side of door body can be synchronously to the center contraction, a body is diminished, belong to dynamo-electric field, the emergency escape when the situation Xiamen such as antitheft and earthquake, fire that are applied to daily house are stuck.
Background technology
At present, the security door on the market mainly contains paling form security door, solid door and with three kinds of the composite gates of both combinations.The difference of different security doors is that appearance design is different with selection, and internal construction is roughly the same, all is frame construction firmly, in conjunction with some plate faces; The function that realizes for open the door, lock a door, pick-proof.But, in case, running into the special circumstances such as earthquake, the stuck back door that causes unblanking of doorframe that security door very likely is bent distortion can't be opened, and indoor occupant can't be escaped.
Summary of the invention
The object of the present invention is to provide an a kind of key to trigger, so that the upper and lower and left side of door body can be synchronously to the center contraction, the mechanical type synchronous door that door is opened.
To achieve these goals, the present invention has taked following technical scheme:
