3 (a) and 3 (b), when the locking device 100 installed in the inner door 200 and the outer door 300 is installed, a rectangular shape is first formed at a midpoint of one side of the inner door 200 And the screw hole 211 is formed on both sides of the bottom surface of the mounting groove 210 after the mounting groove 210 is formed at a predetermined depth.

The fixing bracket 110 of the locking device 100 is inserted into the mounting groove 210 so as not to protrude outside the mounting groove 210 and a key groove And a screw hole 112 corresponding to the screw hole 211 of the mounting groove 210 is formed on both sides of the fixing bracket 110. [

The outer door 300 is formed with an insertion groove 310 having a predetermined depth and a through hole 320 corresponding to the key groove 111 of the fixing bracket 110 is formed on the bottom surface of the insertion groove 310 .

5, the locking body 120 is inserted into the insertion groove 310 of the outer door 300. The locking body 120 has an operation groove portion And an actuating member 130 is installed in the operation groove 121 by a predetermined angle with the hinge part 133 so as to be inserted or protruded outward. At this time, the actuating body 130 protrudes outward by a spring 137 coupled to the hinge 133 and has a somewhat stronger elastic force when the actuating body 130 is inserted into the actuating groove 121 .

It is preferable that a protective wall 136 is formed on both sides of the actuating body 130 so that the fingers do not enter the inside of the actuating groove 121 when the actuator 130 is opened.

A key bundle 131 operated by the key 150 is installed at one end of the actuating body 130 opposite to the hinge portion 133. The key bolster 131 is installed on the bottom surface of the housing 9, a guide groove 134b is formed and an access hole 139 communicating with the guide groove 134b is formed to allow the latching piece 134d to come in and out. A spring 134c is connected to one end of the latching piece 134d, And to be pulled when the piece 134d comes out of the access hole 139.

Then the engaging piece 134d is operated by the rotating rod 134a at the lower end of the key pack 131 so that the rotating rod 134a rotates the key 150 of the key bundle 131 ), It works together.

At the same time, a fixing hole 132 is formed at one side of the operation groove 121 to control the operation of the actuating member 130 by allowing the engaging piece 134d to come in and out. 9 (b), the rotation rod 134a at the lower end of the key bundle 131 moves the retaining piece 134d to the fixed hole (not shown) 132 so that the actuating body 130 is fixed.

7 and 8, the fixing rod 135 is fixed to the bottom of the housing of the key bundle 131 by a predetermined length so that the through hole 122 in the bottom surface of the operating groove 121 And is inserted into the key groove 111 formed in the inner door 200 to lock the inner door 200 and the outer door 300.

The operating body 130 rotates inside the operating groove 121 at a predetermined angle around the hinge 141 to be separated from the engaging protrusion 138 at one end of the actuating body 130, A push button 140 is provided with a spring 142 for pushing the push button 130 outward.

8, when the actuating body 130 is positioned inside the operating groove 121, the engaging protrusion 138 of the actuating body 130 is hooked on one end of the push button 140, The push button 140 is not protruded to the outside and the actuating member 130 does not protrude even when the engaging piece 134d is detached from the fixing hole 132 of the operating groove 121, The actuating member 130 does not protrude to the outside when the engaging piece 134d is caught in the fixing hole 132 of the operating groove 121. [

The operation of the locking device 100 of the present invention having the above-described structure will now be described.

4, the fixing bracket 110 of the locking device 100 is inserted into the mounting groove 210 formed at the midway point of the inner door 200, and then the screw hole 211 The fixing bracket 110 is prevented from protruding outside the installation groove 210 of the inner door 200 to prevent collision with the outer door 300 and scratching.

The locking body 120 is inserted into the insertion groove 310 of the outer door 300 corresponding to the installation groove 210 of the inner door 200 and fixed as a screw.

5 and 7, when the locking device 100 is installed as described above, the operating body 130 is kept open from the operating groove 121 of the locking body 120. [

At this time, when the actuating body 130 is pressed, the actuating body 130 rotates about the hinge 133 on one side as shown in FIG. 8, and the spring 137 is pressed.

When the actuating body 130 is fully inserted into the operation groove 121, the engaging protrusion 138 of the actuating body 130 is seated on one end of the push button 140.

At the same time, the fixing rod 135 located at the lower end of the key bundle 131 on one side of the actuating body 130 passes through the through hole 122 on the bottom surface of the actuating groove 121, So that the inner door 200 and the outer door 300 are simultaneously locked.

When the key 150 is inserted into the key bundle 131 and rotated in one direction in a state where the inner door 200 and the outer door 300 are locked, the key bundle 131 rotates in the housing at a predetermined angle At this time, as shown in FIG. 9, the rotating rod 134a at the lower end of the key bundle 131 rotates together and comes into contact with the engaging piece 134d operated along the guide 134b in the housing.

At the same time, the spring 134c connected to the latching piece 134d is pulled, and the latching piece 134d is pushed by the rotation rod 134a so as to protrude outward from the entry / exit hole 139, The engaging piece 134d is caught by the fixing hole 132 of the operating groove 121, thereby preventing the actuating body 130 from being opened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, and that various changes and modifications may be made by those skilled in the art. It is self-evident that it should be widely protected.
