Abstract
The utility model relates to a safety access door lock self-opening device and a safety access door. The technical scheme is as follows: the safety access door lock self-opening device comprises a door lock, and is characterized in that an unlocking connecting rod is connected with a lock core in a door lock; the unloading connecting rod is connected with a four-link mechanism through a slider mechanism I in a sliding way; the four-link mechanism is connected with a gear I; the gear I is meshed with a gear II; and a motor drives the gear II to rotate. The utility model provides a device which enables the door and the lock to be self-opened in case of disaster.
Description
Technical field
The utility model belongs to safety door latch and safety door field, relates to a kind of safety lock that can open automatically under precarious positions such as fire or earthquake and safety door particularly.
Background technology
In the field of door lock and door, people's research direction all is how can better play antitheft function at present, and seldom considers can open a passage automatically in natural calamity Xiamen such as fire or earthquakes, to reduce casualties.In recent years, fire and earthquake frequently take place, scene in confusion, open or will normally open by the door that door lock will pin because of the door that disaster is out of shape, it all is very difficult thing, if and door and window can not in time be opened in fire and earthquake, bring great inconvenience for people's escape, make people's life security suffer great harm.
Summary of the invention
In order to address the above problem, the utility model provides a kind of device that can door, lock can be opened automatically when disaster takes place.
To achieve these goals, the technical solution adopted in the utility model is: a kind of escape way door lock self-opening device, comprise door lock, it is characterized in that: the connecting rod of unblanking is connected with lock core in the door lock, the connecting rod of unblanking is slidingly connected by slide block mechanism I and four-bar mechanism, four-bar mechanism is connected with the gear I, gear I and the engagement of gear II, and motor drives gear II is rotated.
Above-mentioned escape way door lock self-opening device is characterized in that: can also be provided with warning device, warning device control motor.
A kind of escape way door, comprise door main body, it is characterized in that: above-mentioned escape way door lock self-opening device is installed on the door main body, drive rod is installed on the door main body, one end of drive rod is connected with an end of linkage I by the slide block mechanism II, the other end of bar linkage structure I is connected with the gangbar I, the other end of drive rod is connected with an end of linkage II by the slide block mechanism III, the other end of linkage II is connected with the gangbar II, the gangbar I is connected with control strip with the gangbar II, control strip control safety door.
Escape way door lock self-opening device can be united use with the alarm in the common escape way in use, or uses the fire alarm installation that carries.When breaking out of fire, fire alarm installation control motor start-up is under the drive of motor, gear I and gear II smooth rotation, and drive the four-bar mechanism motion, and then drive the link motion of unblanking, make its overhanging end do the motion of horizontal feed formula, thereby affect lock core that lock is opened.As seen when fire took place, door lock can be opened automatically, thereby the door that will pin is opened.
When earthquake takes place when, the door generation moderate finite deformation that is squeezed.The drive rod that is installed on the door is stressed, affects the one group of linkage that links with it simultaneously, makes it do lever motion, and then the pulling control strip moves, and safety door is flicked.
The beneficial effects of the utility model are: (1) the utility model can take into account door in control lock because the stuck situation of distortion.(2) the utility model can cooperate original alarm use in the escape way, makes it can sense the condition of a fire delicately, not only can report to the police but also door is opened.Therefore, in case during disasters such as breaking out of fire or earthquake, door lock can be opened automatically, and door is opened.When door deforms owing to the reason of disaster, can control safety door automatically and open, also just opened passage, indicator of trapped personnel is withdrawn, reduce injures and deaths.
