Problems solved by technology

However, in case of special circumstances such as an earthquake, the anti-theft door is very likely to be stuck by the bent and deformed door frame, resulting in the door being unable to be opened after unlocking and the indoor personnel unable to escape.

Embodiment Construction

[0019] combine Figure 1-Figure 6 The present invention is described further:

[0020] The mechanical synchronous shrinking door includes a door body, a door lock, a button trigger mechanism, a transmission mechanism and a shrink block trigger mechanism. The door body includes a contraction block and a door panel for fixing the door lock, the key trigger mechanism, the transmission mechanism and the contraction block trigger mechanism. The button trigger mechanism is fixed on the door body, which converts the button action into the rotational movement of the linkage, and transmits the motion to the transmission mechanism, which then transmits the power to the four sets of contraction block trigger mechanisms fixed on the door body. The shrinking block trigger mechanism pulls the large and small shrinking blocks on the door body, so as to realize the synchronous shrinking of the door.

[0021] The door body includes an inner door panel 3, an outer door panel 10, two large shr...

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 [0001] The invention relates to a mechanical synchronous retractable door. The upper, lower and left sides of the door body can be synchronously shrunk toward the center, so that the door body becomes smaller. It belongs to the field of electromechanical and is applied to the anti-theft of daily houses and doors in case of earthquakes and fires. Emergency escape when stuck. Background technique [0002] At present, the anti-theft doors on the market mainly include fence type anti-theft doors, solid doors and composite doors combining the two. The difference between different anti-theft doors is that the appearance design and material selection are different, and the internal structure is roughly the same. They are all solid frame structures, combined with some panels; the functions realized are door opening, locking, and anti-prying. However, in case of special circumstances such as an earthquake, the anti-theft door is likely to be stuck by the bent and def...
