Description

Digital door lock open knob release prevention structure {DIGITAL DOOR LOCK}

The present invention relates to a digital door lock, and in particular, in the open knob installed on the inner body of the digital door lock to operate the dead bolt, a fire occurs in the building, so that the open knob even in a bad condition in which the injection parts of the inner body melt or change. It relates to an open knob release prevention structure of the digital door lock to ensure the operation of the open knob by preventing the elements that drive the departure.

In general, digital door locks are equipped with electronic circuitry to automatically lock and open the door lock by pressing a number button or using a portable remote control. These digital door locks have recently been used in homes and commercial buildings for convenience. The situation is spreading a lot.

In the construction of the digital door lock, an open knob is installed on the inner body. As the open knob is rotated 90 degrees forward and reverse, the key bolt connected to the open knob operates the dead bolt, causing the dead bolt to emerge. Will be locked or unlocked manually.

In the conventional open knob, an injection part such as gears is installed in the process of connecting the key tail to the dead bolt. When a fire occurs in the building and the fire is transmitted to the digital door lock, the injection part including the inner body is opened. Melting or deformation may occur. Accordingly, the assembly structure of the conventional open knob is that the drive elements from the open knob to the key tail are separated from the body, so that the key tail does not operate the dead bolt, so that the door cannot be opened using the open knob, thereby preventing human life in case of fire. You may suffer back damage.

The present invention was devised to solve the above problems of the prior art, the coupler connecting between the open knob and the key tail is mounted on the coupler covering bracket through the coupler covering, and the coupler covering bracket is installed on the outer body By mounting on the mounting bracket, even if the injection body is melted or deformed due to fire, etc., the driving elements of the open knob are not detached, thereby ensuring the operability of the open knob, thereby reducing damages such as human life and providing reliability to the user. It is an object of the present invention to provide an open knob release prevention structure of a digital door lock.

In order to achieve the above object, the present invention,

An open knob installed on the inner body and rotating forward and reverse; A first coupler fixed to the shaft portion of the open knob; A second coupler coupled to the vertical rail portion of the first coupler to enable vertical movement from the first coupler; A third coupler coupled to the horizontal groove of the second coupler to be uneven to move horizontally from the second coupler; In the configuration of the key tail which is installed in the shaft portion of the third coupler is centering and inserted into the key groove of the dead bolt assembly,

A coupler covering coupled to the first coupler;

A coupler covering bracket fastened to the first coupler, covered with the third coupler, and mounted to the inner body;

And a mounting bracket fastened to the coupler covering bracket and assembled with a stud of the outer body.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The digital door lock is generally composed of a dead bolt assembly installed on the side of the door, an outer body and an inner body installed on the outside and the inside of the door, and an electronic circuit is built in to press a number button or use a portable remote controller. It is possible to automatically lock and open the door lock, the key cylinder is installed on the outer body in case of emergency is configured to open the door as a key, the inner body to enumerate the door manually in the room An open knob is installed to actuate the dead bolt assembly when closing or closing.

The present invention relates to the open knob described above.

Figure 1 is an exploded perspective view of the open knob release prevention structure of the digital door lock of the present invention, Figure 2 shows an assembly side view of Figure 1;

As shown in FIG. 1, reference numeral 10 shows an inner body constituting the digital door lock.

The knob ring 14 is installed in the knob installation hole 12 formed in the inner body 10, and the open knob 16 is positioned therethrough, and the first coupler is disposed on the shaft portion 16a of the open knob 16. 18 is inserted to fasten the screw 20 through the screw portion formed in the shaft portion 16a so that the first coupler 18 is fixed to the open knob 16 through the shaft portion 16a, and the first coupler 18 ) Is formed a vertical rail portion 18a protruding across the center of the front surface and the first groove 22a vertically formed in the center of one surface of the second coupler 22 through the vertical rail portion 18a is unevenly coupled. The second coupler 22 is vertically movable from the first coupler 18, and the third coupler 24 through the second groove 22b horizontally formed at the center of the other surface of the second coupler 22. Unevenly coupled with the horizontal rail portion 24a formed horizontally in the center of one surface of the third coupler 24 to enable horizontal movement from the second coupler 22 It said, the second shaft portion (24b) of the third coupler 24, the key tail 26 is inserted into the keyway 102 in the dead bolt assembly 100 is provided.

And reference numeral 28 is a coupler covering is installed so as not to fall out of the first coupler 18, the coupler covering 28 and the coupler covering bracket 30 is mounted to the inner body 10 with a screw 29 It is fastened by a screw 32 and integrated, and the coupler covering bracket 30 covers the third coupler 24 provided with the key tail 26 so that the third coupler 24 does not fall out.

The coupler covering bracket 30 is assembled to the studs 35 of the outer body 34 by the screws 36 and the mounting bracket 38 and the inner body 10 which are assembled through the screws 40 in the inner body 10. Is mounted to the screw 42.
