The present invention relates to a locking device, and more particularly, to a locking device installed on the inside and outside of the reinforcement door to set the locked state of the reinforcement door.

In general, reinforced doors are widely used in various buildings such as government offices, hospitals, and restaurants because of their beautiful appearance and the advantages of being able to check the situation outside the door even in the closed state.

On the other hand, the tempered door has a lot of difficulties in puncturing the hole due to the characteristics of the tempered glass of about 12 mm, and if the hole is punctured, structural problems may occur in the tempered glass. Instead of installing it directly on the top, the metal frame is installed on the upper and lower ends of the tempered glass, and then the locking device is installed on the metal frame.

However, as described above, in order to install the locking device on the metal frame, a hole must be drilled in the metal frame, which is not only cumbersome but also may damage the tempered glass due to the impact generated during the work, and an installation space for installing the locking device. As a result, the small size of the locking device is used compared to the size of the reinforcement door. Thus, a narrow locking device is used in comparison with the size of the door, so that it is difficult to obtain sufficient restraining force, and thus has a disadvantage in that it is vulnerable to external intrusion. In addition, the locking device is installed at the bottom or top of the door, resulting in inconvenience in operation.

On the other hand, Utility Model Registration No. 0511118 discloses a locking device for a tempered glass door in consideration of the above problems. As shown in FIG. 1, the locking device disclosed in FIG. 1 includes a support member 11 fixed to a door, a first operation part 12 installed on the support member 11 to be located inside the door, and an outer side of the door. The second operating part 13 installed in the support member 11, the support 12-1 of the first operating part 12 and the support 13-1 of the second operating part 13 so as to be positioned. It consists of a connecting member 14 for connecting. At this time, the support 12-1 of the first operation portion 12 is provided with a guide hole 12-2 provided with a thread, and another thread coupled to the thread of the guide hole 12-2 is The provided rotary ball 12-3 is connected to the handle 12-4, and the support 13-1 of the second operation portion 13 is provided with a guide hole 13-2 provided with a thread. And, when the rotary hole 13-3 is provided with another thread coupled to this thread is connected to the cylinder 13-4, the operation of setting or releasing the locking of the door in one of the operating parts is made, The other operation on the other side is configured to achieve the same operation.

In addition, Patent Registration No. 0544798 discloses a locking device for a tempered glass door of another structure. As shown in FIG. 2, the disclosed locking device includes a support member 21 fixed to the door, an indoor side locking member 22 installed on the support member 21 so as to be located inside the door, and an outer side of the door. The outdoor side locking member 23 installed on the support member 21, the rotation lever 22-1 of the indoor side locking member 22, and the key cylinder 23-1 of the outdoor side locking member 23. It is composed of an operating member 24 for connecting the locking member of the other while moving up and down during operation of one of the locking member by connecting. At this time, the guide hole 24-1 with the gear mountain engaged with the rotary gear 23-2 installed in the key cylinder 23-1 is provided on one side of the operating member 24, and the rotary lever 22 Another guide hole 24-2 having a gear mountain engaged with the gear shaft 22-2 of -1) is provided on the other side of the operating member 24, so that either the key cylinder or the rotary lever When running, the other one is configured to do the same.

In addition, Utility Model Registration No. 0377449 filed by the present applicant discloses a lock for a reinforced door of another structure. The disclosed locking device is shown in Figure 3, the support member 31 is installed in the reinforcement door, and installed on the support member 31 to be located inside the door, the key cylinder 32-1 and the rotating plate 32- 2) and a rear body 32 provided with a linear motion plate 32-3, installed on the support member 31 so as to be located outside the door, and having a handle 33-1 and a rotating plate 33-2. Connect the front body 33 provided with the linear motion plate 33-3, the linear motion plate 32-3 of the rear body 32 and the linear motion plate 33-3 of the front body 33 It is composed of a connecting pin 34. At this time, gears are formed on the outer circumferences of the rotating plates 32-2 and 33-2 provided in the rear body 32 and the front body 33, and another gear engaged with the linear body 32-3 and 33 is engaged. When the rotary plate is rotated by operating any one of the key cylinder 32-1 or the handle 33-1, the linear motion plate moves linearly and rotates the connecting pin so that it is located on the opposite side of the door. The other linear motion board is configured to move the linear body so that the front body and the rear body work the same.

The above-described conventional locking devices use the principle of the rack and pinion, by which one component rotates when the key cylinder or the handle is rotated, and the rotating component and another geared member are linearly moved. Locks installed on the inside and outside of the door are designed to perform the same operation. For example, in Utility Model Registration No. 0377449, when the rotary plate 32-2 is rotated by the operation of the key cylinder 32-1, the rotary plate 32-2 and the linear motion plate 32-3 meshed with the rotary plate 32-2. The linear movement is performed, and the linear movement plate 33-3 provided on the opposite side of the door, that is, the front body 33, is rotated by the linear movement of the linear movement plate 32-3. This linear movement is intended.

In the case of the rack and pinion gear for each of the locks on the inside and outside of the door to operate in conjunction with each other as described above, the load should be made of sufficient size, but the inside of the lock has a number of parts installed As a result, it is difficult to install a rack and pinion gear having a sufficient size, and thus, a smooth operation is difficult due to wear or breakage of the rack and pinion gear during long-term use of the locking device.

The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a locking device for a reinforcement door capable of securing sufficient rigidity and simplifying the structure by using a protrusion and a groove in place of the rack and pinion. .

The present invention to achieve the object as described above and to perform the problem for eliminating the conventional drawbacks is installed to extend from the inner side of the door to the outside and the support member is provided with a connection member installation hole penetrating both sides;

It is installed on the support member so as to be located inside the door, and is provided with an inner rotary hole for setting or releasing the locked state of the door by rotating the lever member by the operation of the lever to release the latch member, by the inner rotary hole and the rotary connection means An inner locking member rotatably coupled and provided with an inner movement hole for angular movement together with a rotation movement;

It is installed on the support member so as to be located outside of the door, and the outer rotary hole which is rotated by the operation of the key cylinder and the outer rotary hole which is rotatably coupled by the outer rotary hole and the rotary connection means to perform the angular movement with the rotary movement Outer locking member provided with; And

The inner moving hole and the outer moving hole are connected, but the center is supported by the connecting member installation hole, and both ends are composed of a plurality of steel wires for angular movement, both ends of the through hole formed in the inner moving hole and the outer moving hole. Is fitted to each, characterized in that the locking device for the reinforcement door consisting of a connection member that is fitted to move along the steel wire inward and outward movement port according to the rotation angle.
