Embodiment Construction
[0022] Such as figure 1 As shown, the anti-theft door with an emergency opening device is composed of a door panel 12, a door frame 13 and an emergency opening device 15. The emergency opening device 15 is installed in the door frame 13, and consists of an emergency handle 1, a bevel gear 2, a bevel gear 3, and a main drive Shaft 4, support bearing seat 5, drum cam 6, cam follower 7, slider 8, slide rail 9, hinge lower tube angle 10, hinge upper tube angle 11, door panel 12, door frame 13 and installation base plate 14.
[0023] Such as figure 1 with 2 As shown, bevel gears include vertical bevel gear 2 and horizontal bevel gear 3. The vertical bevel gear 2 is a large gear, and the horizontal bevel gear 3 is a pinion. 3 are meshed with each other, the rotation axis of the bevel gear 3 is the main transmission shaft 4 parallel to the vertical direction of the door panel 3, the rotation axis of the bevel gear 2 is connected to the emergency handle 1 through the door frame, and...

The invention relates to a burglar-proof device with an emergency opening device and aims at providing a mechanical device which has simple and reliable design and can open the door in time when a disaster happens to allow people to escape, can solve the problems the door cannot be opened when the disaster happens due to the deformation of a door lock and a door body and the like and greatly increase the possibility of escape when the disaster happens. The technical scheme for achieving the aim comprises that the burglar-proof door with the emergency opening device consists of a door panel, adoor frame and the emergency opening device, wherein the emergency opening device is arranged in the door frame; a hinge for connecting the door panel and the door frame consists of two parts which can be separated up and down; and the emergency opening device is connected with one part of the hinge to drive one part of the hinge to move in the vertical direction, so that the two parts of the hinge are separated.
Description
technical field [0001] The invention relates to an emergency opening method and a mechanism for an anti-theft door when a disaster occurs. Background technique [0002] With the development of the national economy and the continuous advancement of the urbanization process, more and more people live in high-rise buildings, so the use of anti-theft doors is becoming more and more common. Less hidden dangers. For example, in some disasters, especially when a fire occurs, the best time for escape and rescue is often delayed because the anti-theft door is difficult to be opened in time. It is the key to saving lives, and the door opened at this time is the "gate of hope" and "gate of life". [0003] At present, there are many kinds of escape devices for closing doors on the market, most of which are in the form of escape door locks. They sense the fire through sensors, and then open the door locks through electromagnetic reactions to open the escape passage. The advantage of t...
