Description

Electric Locking Device

The present invention relates to an electric well, and more particularly, by using a dead cam rotated by the driving of the motor to allow the dead bolt to be drawn in or drawn out so that the locking (unlocking) of the door is made by the solenoid Not only do you use the power of the electric motor, but also simply use the components, and if you set the door safe (fail safe) in case of power failure, the door lock and unlocking is normally performed for a certain time during power failure. If the door remains open after this time is set, and the door is set to fail secured in case of power failure, the door lock and unlocking is normally performed for a certain time, and then the door remains closed after a certain time elapses. It is about electric well.

In general, doors are installed at homes, offices, hospitals, buildings, government offices, schools, hotels, and performance halls to prevent external intrusion. These door locks are mainly used for keys to unlock doors. An electric well using an electric power and electric power is being used.

In the case of double electric wells, an electric electronic digital door lock is used, and the digital door lock additionally used for the door is kept locked when the lock latch is inserted into the groove of the outer frame, and the lock latch is formed on the door frame. It is configured to release the door lock state from the groove.

That is, in the conventional configuration of the electric tablet, the key press plate and the key release plate formed with a key press piece for activating and releasing the drive shaft connection key by the solenoid operated at the same time as the password is released by pressing a button formed on the outer body. And a pull plate having a pull rod coupled by connecting a drive shaft having a drive arm actuated by drawing in and out of the drive shaft connecting key, and a vane clasp pulled by the drive of the drive arm and returned by the return spring with a connecting piece; It is installed on one side of the pull plate and is provided with a horizontal retaining guide piece which is pulled and pushed by the driving arm and is located in a horizontal retaining groove formed with a moving groove, and a moving groove formed in the horizontal retaining hole and fixed by a stopper shaft to rotate at a predetermined angle. Stopper disengagement port and stopper to be operated, and release catch and release port to be operated by the stopper A locking latch having a locking release mechanism having a tooth piece, an interlocking shaft having an interlocking arm operating in conjunction with the drive of the driving arm, a locking latch having a latching jaw pulled by the interlocking arm of the interlocking arm and returned by a spring; Consists of a structure coupled to the latch having a latch release piece and the latch latch piece for locking and releasing.

In the conventional electric door lock configured as described above, when external power is supplied to the solenoid configured therein, the driving shaft connection key is operated by a key pressing plate formed with a key pressing piece formed by drawing out the pressing piece coupled to the solenoid and operating the pressing piece. As the driving shaft and the driving arm are rotated integrally to move the pull bar to move the vandal latch connected to the pulling plate to the opposite side of the door frame, the driving arm pushes the linking arm formed on the interlocking shaft, so that the locking latch moves. The locking latch on the door is pushed in and out to lock and unlock the door.

Such a conventional electrostatic tablet has a problem that many components are required because the components are operated in conjunction with each other by a solenoid, so that the configuration is complicated.

In addition, since the solenoid is provided with moisture in summer, such as in the rainy season, the solenoid often does not operate due to the dew condensation in the winter, and thus the door cannot be opened and closed.

In addition, a constant distance must be maintained between the driving arm, the linkage arm, and the locking clasp in order to operate the locking clasp. As a result, the shortcomings that are easily solved when a small shock or forcible opening are attempted from the outside are caused. have.

In addition, there are a number of components installed in the interior space, the structure is complicated, difficult to manufacture and assembly, the manufacturing cost is high, there are problems such as causing a failure due to many parts.

In addition, the conventional electric boat has a security problem that the dead bolt is pushed into the inside when a certain force is applied from the outside.

Accordingly, an electric well having a motor other than the conventional solenoid type has been devised, and for example, an electric well having an automatic locking function has been devised.

This prior art simplifies the components installed inside the electrostatic well, while automatically performing the rotational operation of the dead cam for locking and releasing the dead bolt constituting the electrostatic well. In this way, it is possible to increase the economic efficiency due to cost reduction and to make the assembly easy because of its simple structure.

However, in the case of the prior art, even if the configuration is provided with a forward and reverse motor, the dead bolt operating portion for operating the dead bolt is rotated by the rotation of the forward and reverse motor installed in the door, and the dead cam portion at one end A seating groove is formed to be coupled to, and the opposite end is composed of a dead plate coupled to the dead bolt, the dead cam portion is coupled to the dead rotary shaft coupled to the manual rotary pin is connected to the stationary motor, the dead rotary shaft Composed of a dead cam fitted to the outer periphery of the dead cam and a dead cam stopper coupled between the dead rotating shaft and the dead cam, the components for drawing in and out of the dead bolt are complicated, resulting in simplification and cost reduction of parts. It is not enough to increase the economic feasibility and the complicated structure makes the problem that assembly is not easy. The.

In addition, in the case of the conventional electric well, if a fire or the like does not apply electricity to the stationary motor, the operation of the stationary motor is not possible, which makes it difficult to evacuate the inhabitants.

In addition, in the case of a fire door, the fire doors must be locked again after the internal residents evacuate quickly, but when the internal residents evacuate quickly, the electric boats released by the evacuation action cannot be locked again. Of course, there is another problem that the flame spreads.

In other words, fire doors should be opened for evacuation even if a power outage occurs due to a fire, and should be closed after evacuation to prevent the spread of flames due to fire. When placed, there is a problem that a lot of casualties and property damage occurs because it is not opened in the locked state or closed in the unlocked state.

In addition, if the conventional electric well is set to fail safe during a power failure, the door is opened unconditionally so as not to be trapped inside, such as a hospital or a library, in an emergency situation such as a fire. There is a problem that the door continues to open even after the flame or smoke is quickly spread through the open door.

In addition, if a conventional electric well is set to fail secure in case of power failure, the door remains closed in the event of a power failure, such as when important data of a bank or a company is stored. There is a problem that can not be.

In other words, if a conventional electric well is set to fail secure in case of a power failure, the door is kept unconditionally to prevent people from entering from inside to outside. There is a problem that people such as patients can not escape.
