Electric RIM lock is a kind of electric lock with a large amount of use. It can be opened electronically or with a key. It is mostly used in building intercom doors (also called electric doors) in residential areas. It is the veteran of electric locks. For a period of time, it represented the electric lock, and now people often use the electric lock as a general term for all electric locks. However, because it cannot be set to normally open and normally closed, it is rarely used in access control.
The electric RIM lock has two lock pins, one is smaller, this is not a lock pin, it is used to store energy, its function is to store energy when the door is closed, so that the lock pin can bounce back when unlocking, so this small The energy storage lock plug corresponds to the position where the lock box has no opening, and the other lock plug is larger. This is the real lock plug. When installing, this lock plug should correspond to the lock position of the lock box. The inside of the electric lock is a set of linkages. When the door is closed and the electric lock is locked, the large lock inserts into the lock, and the small lock insert used to store energy is squeezed, and the spring of the linkage stores energy, which is used for electric power. The spring of the electromagnetic coil for unlocking supports a metal piece to lock the linkage, and the electric control lock is locked. When opening the door, only a short-term current is needed to the electromagnetic coil, the electromagnetic coil forms an attractive force, and the metal piece of the linkage is stuck. Being sucked away, the entire linkage, driven by the previously stored elastic energy, pulls the large latch to open. The electric lock is also equipped with a set of keys and lock cylinders, as well as an internal knob or button. You can manually use the key outside the door to directly toggle the linkage with the linkage device to open the electric lock, or you can press the lock inside the door. The button on the lock is unlocked, that is to say, the access control uses the electric control lock to save the exit button, and directly press the button on the electric control lock (or rotate the knob) to open the electric lock when going out.
Electric RIM locks are suitable for installation on iron doors, especially for building iron doors for building intercoms. In order to make the installation of electric locks more secure, if you install electric locks directly when making doors, it is usually installed on the door leaf electric lock. Install the embedded parts to support and fix the lock body, and then try to install the lock at the position of the reinforcing rib of the door, or simply make a large back plate and install it at the position of the lock. Adding a back plate is to increase The strength of the door makes the installation of the electric lock more firm. Even if it is a door that is not opened frequently, the outlet of the door frame should be protected to prevent the lock wire from being pinched by the door. Because a key needs to be installed, in order to open the door conveniently, the installation height of the electric lock is generally 80cm-100cm from the ground.
Once the electric RIM lock is unlocked manually or electrically, if the door is not opened and closed again, the electric control lock will always be in the unlocked state and will not close automatically, so some places with high safety requirements must choose the electric door lock carefully.
The two wires of the electromagnetic coil of the electric lock are not divided into positive and negative, so the color of the two wires is generally not distinguished. As long as there is enough current in the coil, the lock will be unlocked.
Some electric RIM locks have made certain improvements on the basis of the original standard electric control locks, including installing a small wheel on the energy storage lock, which reduces the noise to a certain extent.
