By the way, the conventional door check has the advantage of automatically closing the door by pulling the fire door, but also has the disadvantage of making the opening difficult.
In order to open the fire door in which the door check is installed, the force of the door check that pulls the fire door as well as the force of the door check that pulls the fire door, ie, the tension of the cylinder or the spring, must be opened to open the fire door.
Therefore, in a building where a fire door is to be opened, remove the door check or fix the door by hanging the fire door.
Recently, a device capable of controlling the door check and opening and closing the
For example, the door check of the Korean Utility Model Registration No. 431191 uses an electromagnet, and is equipped with a locker connected to the electromagnet to allow the
A hydraulic door check is provided on a door that rotates about a hinge on one side of the wall so that the other side of the first operating rod, one side of which is fixed to the inner surface of the door, is connected to one side of the second operating rod through the rotating shaft, and In the automatic closing device of the door to the other side is engaged with the rack formed on the outer surface of the hydraulic cylinder receiving the spring elasticity by coupling the gear through the shaft, the hydraulic cylinder is to prevent the movement selectively by the rocker moving up and down AC power or internal battery power from the outside is supplied directly to the electromagnet through the switch contact point, and to the fire detection sensor through the contact point. When supplied to the electromagnet through a backflow prevention diode, it is directly attached to one side of the door. Pro is configured to be supplied.
However, these devices have some problems.
First, the rocker, or electromagnet, directly controls the hydraulic cylinder, so that a large-capacity electromagnet is needed to overcome the pressure of the hydraulic cylinder, and as the locker is installed through the door check, the confidentiality of the hydraulic door check is required. It is also difficult to do, and there is a problem that frequently occurs.
Second, there is a problem that the rocker for cracking down the hydraulic cylinder may be bent or bent by hydraulic pressure to lose the original function of closing the
Third, such a device has a problem that the management room or the person who does not know the presence or absence of fire or the opening and closing state of the door.
Fourth, there is a problem that the above-mentioned device is manufactured integrally with a device such as a door check and a rocker for controlling the same.
In other words, such a device is assembling as well as locker and the like in the manufacturing process of the door check, as well as manufacturability and workability significantly reduced, there is a problem that the entire door check must be replaced in case of failure.
