Introduction of Electric Bolt Lock

June 20 , 2022

Electric Bolt Lock or electric control lock is an electronically controlled lock that drives the "bolt" to extend or retract through the on-off of current to achieve the function of locking or opening the door. Of course, the realization of the function of closing the door and opening the door needs to cooperate with the "magnetic sheet" to realize it.

Electric Bolt Lock

Usually, the Electric Bolt Lock consists of two main parts: the lock body and the lock hole. The key component in the lock body is the "lock tongue", which can realize the two states of "closing the door" and "opening the door" in cooperation with the "lock hole". That is, the lock tongue is inserted into the lock hole to close the door, and the lock tongue leaves the lock hole to open the door. It is precisely because of the retractable function of the bolt that it is given the name of "Electric Bolt Lock". It is precisely because of this feature that Electric Bolt Locks are often used on various swing doors (two-way opening). At the same time, its "hidden" installation feature is more suitable for places with high requirements for the confidentiality of the lock body.


The current Electric Bolt Lock is divided into two types, power-on unlocking and power-off unlocking, that is, the state of the former when the power is off is that the lock tongue is in the inside to open the door, and the latter is vice versa. However, under normal circumstances, the fire protection requires that the door be opened with a power outage to prevent it from being automatically opened when a fire occurs!

Electric Dropbolt Lock

The current Electric Bolt Lock has 2 cores (power supply +12V and -12V), 5 cores (power supply +12V and -12V and two status points and common points of door magnetic) and 8 cores (power +12V and -12V and door magnetic There are two state points and common points, as well as three points of the lock cylinder).


The simple way to distinguish the quality of the Electric Bolt Lock on the surface is to look at the appearance, and another simple way is to weigh it by hand. Generally, good quality is heavier.


When installing, it is necessary to install the lock body (including the lock tongue part) in the spine, and then install the lock piece (including the lock hole part) on the upper part of the movable fan. When installing, it is necessary to pay attention to adjusting the corresponding position of the lock tongue and the lock hole, as well as the corresponding position between the floor spring and the floor lock. For framed glass doors, a lock plate can be used; but for frameless glass doors, a small door clip "lower bracket" must be used to act as a keyhole.


Electric Bolt Locks have the following properties:

Electric Bolt Lock

1. Lock tongue strength: If the lock tongue is weak, the phenomenon of automatic retraction of the lock tongue will occur, or the response force is poor, the lock tongue expansion and contraction is not timely, and the meaning of "lock" will be lost.


2. Lock body temperature in working state: There is no Electric Bolt Lock that does not heat up in working state, but it should not reach the level of "boiled eggs".


3. Working current: This indicator is related to the strength of the lock tongue and the temperature of the lock body in the working state. A well-designed Electric Bolt Lock should find a balance between these two.


4. Working voltage: There are usually two types of 12VDC/24VDC, and most of them are 12VDC. The biggest benefit of 24VDC is that it requires less operating current.


5. Lock body size: This indicator is particularly important for places with special installation dimensions. Some engineering dimensional requirements cannot be achieved by design.


6. Feedback signal: Some Electric Bolt Locks provide detection functions for the lock status, such as detection of the position of the magnetic plate, detection of the status of the lock cylinder, etc. Higher security requirements can be achieved.


7. Delay design: the door can be automatically closed after a delay of several seconds after opening the door. This function is designed for some access control systems that cannot be set to delay.
