Description

Lock and Key {Doorlock and Key}

The present invention relates to a door lock device and a key to lock the door, and more specifically, to secure the door lock by configuring to use only a dedicated key when opening or locking the door outdoors or indoors. In addition, the present invention relates to a door lock and a key that enhance safety by disassembling it from the outdoors or indoors.

Anxiety is increasing in the lives of the common people due to the rapidly increasing crimes. Accordingly, various security devices are developed and used. However, since most security devices use expensive and complicated devices such as closed circuit TVs and remote control devices, the spread to the common people is being delayed. Moreover, door locks, which are the first prevention means used to prevent crimes, are not yet effectively used for crime prevention and prevention because they are still well exposed to criminals.

Conventionally used locking device is composed of a lock that locks the door, and a key for opening the lock, most of the lock is made of steel, because the structure is easily removed by damage or manipulation from the outside, the key becomes obsolete. Most of the time. In addition, since the key itself has a simple shape of a square with a large number of bends on the surface, it is easy to duplicate and there is a high risk of damage when the lock is opened and closed.

Another object of the present invention is to provide a high security and low cost door lock and key in the case of locking the door.

Door lock device of the present invention for achieving the above object, the key groove for receiving the key is formed by a predetermined distance spaced around the reinforcement fixed to the end, separated by a pair of iron pieces supported by an elastic spring 5 The key operating unit main body having four stop protrusions inserted in eight rows along the circumference, and a rotating part in close contact with the key operating part main body and penetrated by a part of the stopping protrusion are installed, and the rear end of the rotating part is fixed by a rotating member. Is connected, the front of the rotating portion is a key operating unit is provided with a reinforcing material and a fixing member by a screw; A gear mechanism connected to the rotary rod of the key operating unit and operated according to the rotational state of the rotary rod, a fixed rod moving forward or rearward according to the operating state of the gear mechanism, and installed on an upper side of the fixed rod. A main body including a stop rod which is always protruded when the door is closed and is supported by a spring to prevent the door from being opened automatically, and a locking member for fixing the stop rod; And a key storing portion attached to a surface of the main body, and having a key groove formed at an outer surface thereof, and having an inner end portion for moving the fixed rod back and forth, which is connected to a gear mechanism and connected with an operating rod which rotates according to the operation state of the key. It consists of. In addition, the key for operating the locking device is composed of eight key projections formed with five key grooves having different depths on each surface and formed with reference projections, and the other end has a spring inserted into the handle. When the pressure is released is characterized in that the handle portion is configured to protrude to the outside.

A key storage unit for opening the door using a key in the room, a fixed rod which protrudes to the left and is inserted into the fixing latch to fix the door, and a stop rod which is installed on the upper side thereof to prevent the door from opening and closing. Is indicated. In addition, the other end located on the right side of the drawing is provided with a locking member for holding the stop rod in a locked state. Although not shown in the opposite position of the key storing portion, the key hole at the end is exposed to the outside, and the key operating portion is disposed between most of the doors.

The fixed rod is configured to move left and right when locked or opened using a key, and the stop rod on the upper side serves to simply fix the door so that it does not open automatically when the door is closed. But in order to open and enter from the outside, of course, you have to open it with a key. A spring, or an elastic member is installed inside the stop rod for this purpose, and it will be readily understood that this is a conventional method. When the stop rod is also necessary, that is, to securely lock the door at night, it can be fixed so that it is impossible to move using a locking member. In this case, therefore, a person must open the door directly.

As described above, according to the present invention, a criminal can provide a door lock device and a key having a structure in which a criminal cannot open, close, or break a lock without a key, and in addition, a high security and low price door when locking a door There is an advantage in providing a lock and a key.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention, and such modifications or changes belong to the appended claims.
