Detailed Description

For a better understanding of the objects, structure and function of the present utility model, an emergency opening device for a safety door according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, an emergency opening device for a safety door comprises a door leaf 1 and a lock body 4, wherein the lock body 4 comprises an indoor handle 41, an outdoor handle 42 and a lock cylinder linkage mechanism, the lock cylinder linkage mechanism acts to retract a bolt 43 on the side face of the lock body 4 and a bolt 43 on a latch transmission mechanism 5 connected with the lock body 4, the indoor handle 41 and the outdoor handle 42 are connected with the lock cylinder linkage mechanism, and the lock cylinder linkage mechanism can be acted by rotating the indoor handle 41 or the outdoor handle 42.

The indoor panel of door leaf 1 is last to set up depression bar subassembly 2, and depression bar subassembly 2 includes horizontal pole 21 that sets up, and the vertical pole 22 in stretching into door leaf 1 is connected to the both sides of horizontal pole 21, and vertical pole 22 connects the depression bar drive mechanism 3 that sets up in door leaf 1, and the lock core link gear of lock body 4 is connected to the output of depression bar drive mechanism 3, thereby exerts pressure accessible depression bar drive mechanism 3 to the horizontal pole 21 and transmits lock core link gear and withdraw bolt 43 and open the emergency exit.

In this embodiment, the compression bar assembly 2 is disposed at the lower side of the lock body 4, the longitudinal bar 22 is an upwardly curved arc bar, the middle part of the longitudinal bar 22 is mounted on a first fixing shaft 34 parallel to the transverse bar 21, and the first fixing shaft 34 is mounted on the back of the indoor panel of the door leaf 1. The compression bar transmission mechanism 3 comprises a first connecting plate 31, a second connecting plate 32 and a third connecting plate 33, wherein the first connecting plate 31 is connected between the end parts of the longitudinal bars 22 on two sides far away from the cross bars 21, the middle part of the second connecting plate 32 is arranged on a second fixing shaft 35 perpendicular to the front surface of the door leaf 1, and the second fixing shaft 35 is arranged on the back surface of an outdoor panel of the door leaf 1.

The second connecting plate 32 is inclined, the lower end is far away from the lock body 4 and is provided with a third fixed shaft 36 which is connected with a slotted hole arranged on the first connecting plate 31, the upper end is close to the lock body 4 and is provided with a fourth fixed shaft 37 which is connected with a slotted hole arranged on the third connecting plate 33, the third connecting plate 33 is connected with a lock cylinder linkage mechanism of the lock body 4, and the end parts of the second fixed shaft 35, the third fixed shaft 36 and the fourth fixed shaft 37 are limited by using a bayonet lock.
