Description

Electromagnetic lock with fixed frame {Electromagnetic lock with fixed frame}

The present invention relates to an EM lock in which a fixed frame is coupled, and more particularly, an EM lock, an opening and closing device that opens or closes a door using the magnetic force of an electromagnet, and a fixed frame that can prevent separation by fixing it. It is about EM lock that is combined.

EM lock (EM lock) is mainly used for one-way doors such as fire doors, wooden doors, and glass doors, and is widely used as an opening and closing device that opens or closes a door by using the magnetic force of an electromagnet. It is generally installed on the top or side of a door that is opened and closed, and through this, it provides a locking function without shaking and allows opening without jamming when unlocking. The components of EMLOCK are located close to each other when the door is closed, which is installed on the door frame to supply and cut off power to control the flow of current to the electromagnet, and is installed on the door that opens and closes. It may be composed of an armature, which is a ferromagnetic material configured to come into contact with the lock body.

In order to control the door to be opened and closed as described above, and to control the security of the door, the locking body is installed on either a door or a door frame, and an electromagnet is provided therein in Korean Patent Registration No. 10-2011265; A counter body portion installed to face the locking body portion at the other side of the door or door frame other than where the locking body portion is installed, and formed of a ferromagnetic body; A controller unit controlling on/off of the power supplied to the locking body; And a server that controls the operation of the controller unit and monitors the operation of the controller unit and the locking body unit.

However, the EMLOCK system described above is intended to provide a function to remotely manage and monitor the door control, and is expected to respond quickly in case of an emergency situation.This prevents the intentional situation of attempting to unlock the EMLOCK device. There is a limit to the configuration of EM Lock for monitoring, and there is a burden for the administrator to grasp the environment in real time for monitoring.

Republic of Korea Patent Publication No. 10-2011265 (2019.08.09)

In order to solve the above-described problems, the present invention provides an EM lock with a fixed frame for controlling the opening or closing of the door by using the magnetic force of the electromagnet and maintaining a stable coupling. It provides an EM lock with a fixed frame that prevents attempts to separate EM lock with physical force, and enables stable access control by disseminating the situation through immediate notification when there is an attempt. It aims to be.

The configuration for achieving the object of the present invention is composed of a main body configured to outwardly form an electromagnet whose magnetic force is controlled by supplying or blocking power to one side and a coupling part consisting of an armature formed of a ferromagnetic material facing the electromagnet. The electromagnet is configured to protrude and extend from the lower end of the main body to the surface facing the armature.

As described above, according to the present invention, when the main body including the electromagnet and the ferromagnetic armature come into contact, the main body is intentionally used in an environment where the door can be controlled through an EM lock locked by magnetic force. When attempting to separate the coupling part between the part and the armature, the fixing frame formed by extending from the body part hides the coupling part, thereby maintaining the fixing force of the door lock and preventing damage to the device.

In addition, when an object is approached with EMLOCK for the purpose of intentionally damaging the device or opening an unauthorized door, attempts to damage any door control environment by detecting it through the proximity sensor included in EMLOCK and ventilating the surroundings through an alarm. Becomes able to control.

1 is a schematic perspective view of a conventional EM lock.
Figure 2 is a front view of the main body portion of the fixed frame is coupled EM lock according to the present invention.
Figure 3 is a left side view of the bonding state of the fixed frame is combined EM lock according to the present invention.

Hereinafter, FIGS. 2 to 3 are a front view and a left side view of the combined state of the EM lock to which the fixing frame according to the present invention is coupled, and a detailed configuration of the present invention will be described with reference to this.

In the EM lock to which the fixed frame of the present invention is combined, the body part 10 in which the electromagnet 11 whose magnetic force is controlled by supplying or shutting off power to one side is configured to be outwardly; and facing the electromagnet 11 A coupling part 20 composed of an armature 21 formed of a ferromagnetic material; and the electromagnet 11 has a bottom surface and a side end of the main body 10 on a surface opposite to the armature 21 A fixed frame 12 protruding and extending is included, and the fixed frame 12 is provided with a side end extension frame 12a at both side ends and a lower end extension frame 12b at the lower end, the main body 10 and the When the armature 21 is coupled, the armature 21 is inserted into the fixing frame 12, which is a protrusion, so that the fixing frame 12 surrounds the armature 21. In detail, the lower extension frame 12b forms a stepped portion 12d from the end length of the upper frame 12c to the lower end, and is bent toward the armature 21 to extend, and the side extension frame 12a is The lower extension frame 12b is bent and formed to have the same length as the extension. The lower extension frame 12b of the fixed frame 12 is configured so as not to interfere with the coupling with the armature 21 by securing a space by forming a step.

In the closed state in which the entrance door is closed, the fixing frame 12 abuts and is coupled to the main body 10, but the protruding length of the fixing frame 12 extending to the lower end and the side of the main body 10 is combined. It is configured not to be longer than the length of the vertical armature portion (21a) of the armature (21). When the door is closed through this, it is configured not to contact the surface of the door closed by the fixed frame 12 protruding from the main body 10 so that no space is generated between the armature 21 to be bound. It is for sake.

In addition, a proximity sensor 13 for detecting the presence or absence of an object approaching at a certain distance is included on the lower surface of the main body 10, and an alarm notifying an alarm for this when the proximity sensor 13 detects an object ( 14) is characterized in that it is provided. The proximity sensor 13 may be provided at a desired position at the lower end of the main body 10 toward the lower end. In addition, the alarm device 14 may also be provided at a desired position on a surface or a bottom surface where the body portion 10 is coupled to the armature 21.

This is because when an object is approached by EMLOCK for the purpose of intentionally damaging the device or opening an unauthorized door, it is detected through the proximity sensor 13 included in the EMLOCK and the surroundings are ventilated through the alarm 14. Any attempt to compromise the door control environment can be controlled.

According to the above configuration, according to the present invention, when the main body including the electromagnet 11 and the armature 21, which are ferromagnetic, come into contact, the door is intentionally controlled in an environment where the door can be controlled through an EM lock that is locked and fixed by magnetic force. When attempting to remove the coupling part between the main body and the armature using a tool, the fixing frame formed by extending from the main body neutralizes the attempt by hiding the joint connecting the lower end and the side, thereby maintaining the fixing power of the door lock. It maximizes the security of access by providing an effect to prevent damage to the security.

Although the present invention has been shown and described in connection with a specific embodiment, it is known in the art that various modifications and changes are possible within the limit without departing from the spirit and scope of the invention indicated by the appended utility model claims. Anyone who grows up will be easily aware of it.
