Escape lock is a kind of door lock device which provides convenience for evacuation in sudden disasters such as fire and earthquake. It is mainly installed in emergency exits of public places and enterprises and institutions.
1. Design principle of escape lock
(1) Safety and reliability: As an important tool to protect people's lives and property, the escape lock must have high reliability to ensure normal use under any circumstances; At the same time, it is also necessary to avoid illegal destruction or misoperation;
(2) Simple operation: people are often in a state of panic when disasters occur, so it is required that the operation method of the escape lock should be simple and clear, and even untrained people can quickly master it;
(3) Careful protection: it is necessary not only to prevent internal personnel from opening it without authorization, but also to ensure that external rescue forces can open it smoothly for rescue; In addition, it must have certain anti-theft performance to reduce property losses;
2. Main structural components and their functions
(1) Handle mechanism: the handle part located at the outside of the door is used for normal entry and exit, and the door can be unlocked only by pressing the handle directly when it needs to be evacuated quickly in case of danger;
(2) Lock body assembly: it mainly includes lock tongue, transmission shaft, electromagnet and other parts, and realizes opening and closing control through the principle of mechanical linkage;
(3) Alarm system: built-in buzzer and LED indicator light, once someone tries to enter from the outside, it will immediately send out an audible and visual alarm to remind the surrounding area to pay attention and attract attention;
(4) Power supply module: battery power is used to support the operation of various functions, and regular inspection and replacement are carried out to ensure that the power is sufficient and will not delay the use at critical moments.
3. The specific workflow is illustrated with examples.
Suppose there is a sudden fire in a hotel room, and the corridor outside the room is full of smoke and impassable:
(1) The customer can quickly press the safety hammer set at the door to break the glass cover and expose the emergency pull ring;
(2) At the same time, the door handle is forced outwards to drive the connecting rod to retract the lock tongue to complete the unlocking action;
(3) After the door is pushed open, transfer to the nearest safety exit along the predetermined route according to the fluorescent guiding signs laid on the ground;
During the whole process, the explosion-proof transparent cover made of special materials effectively prevented the flame from spreading to the handle, and the equipped high-decibel sound reminded the staff to take corresponding measures in time, which made the rescue operation more efficient and orderly.
The above is some introduction to the "escape lock", hoping to help everyone!
