Is made of. The position of the locking pin groove 435 is formed at a position corresponding to the position of the locking pin groove 443 of the spacing disk 44.

According to the above configuration, the operation of the cylindrical locking device using a disk according to an embodiment of the present invention is as follows.

A plurality of key disks 45 are mounted in the inner space of the body 434 of the cylinder 43, and a space disk 44 is provided between the front of the key disk 45 and the key disk 45. do. At this time, the rotation preventing portion 442 of the spaced disk 44 and the rotation locking portion 452 of the key disk 45 is to be seated in the opening 433. Next, the guide portion 412 of the guider 41 enters the passage hole 441 of the spaced disk 44 and the keyhole 451 of the key disk 45 so that the guider 41 is provided so that the inner cylinder ( 4) Assemble.

Subsequently, assembly is performed by inserting the inner cylinder 4 assembled in this way into the inside of the outer cylinder 2. In this case, the locking pin 5 is interposed between the locking pin hole 435 of the lower portion of the cylinder 43 of the inner cylinder 4 and the locking pin seating groove 21 of the inner surface of the outer cylinder 2. Assemble as much as possible. When the inner cylinder 4 and the outer cylinder 2 are assembled in this way, the engaging portion 24 is formed on the front surface of the outer cylinder 2 so that the inner cylinder 4 does not come out of the outer cylinder 2.

Next, by coupling the stopper pin 3 to the stopper pin insertion hole 22 formed through the outer portion of the outer cylinder 2, the end of the stopper pin 3 passes through the stopper pin insertion hole 22 to allow the inner cylinder to pass through. Assemble so that it seats in the stopper groove 431 of the cylinder 43 of (4). When the stopper pin 3 is thus assembled between the inner cylinder 4 and the outer cylinder 2, the angle at which the inner cylinder 4 is rotated inside the outer cylinder 2 is limited by the stopper pin 3. .

After the assembly is completed as described above, the process of locking or opening the locking device using the key (1) is as follows.

When the user inserts the key 1 into the key entry hole 411 formed in the guider 41 of the inner cylinder 4 penetrated in the front center of the outer cylinder 2, the key 1 is the guider 41. It is sequentially inserted into the through hole 441 of the spaced disk 44 and the key hole 451 of the key disk 45, which are arranged along the guide rail 413 of ().

Next, when the user turns the key 1, the plurality of stepped surfaces formed on the key 1 and the key holes 451 of the plurality of key disks 45 are rotated correspondingly to each other. The rotation of the key hole 451 is rotated differently according to the difference in the step surface formed in the key 1, the rotation locking portion 452 of the key disk 45 is constrained by the cylinder 43 It is rotated within a certain angle range, and rotation above it is prohibited.

As the plurality of key disks 45 are rotated differently according to the difference in the step surface of the key 1, the locking pin grooves 453 formed at different positions of the lower portions of the plurality of key disks 45 are formed in the outer cylinder 2. Locking pin grooves of the outer cylinder 2 as shown in FIG. 10 together with the locking pin grooves 443 of the spaced disks 44, which are arranged in a line above the locking pin grooves 21 of 21, a space in which the locking pin 5, which is seated on the upper surface, can rise. As the rotational force is applied to the inner cylinder 4 by the force by which the user rotates the key 1 in this state, as shown in FIG. 11, the inner cylinder 4 which forms an interface with the outer cylinder 2 is shown. When the cylinder 43 starts to rotate in the direction of the arrow with the spacing disk 44, the locking pin 5 moves together with the cylinder 43 while the outer cylinder 2 is fixed. The wall of the semi-circular locking pin groove 21 of the outer cylinder (2) is raised to enter the locking pin groove 453 of the key disk 45 and the locking pin groove 443 of the spacer disk 44, In this way, while the locking pin 5 enters the locking pin grooves 453 and 443, the inner cylinder 4 continues to rotate. When the inner cylinder 4 is rotated in this way, the locking ring (not shown) attached to the rear portion of the inner cylinder 4 is rotated to release the locking by releasing from the latch (not shown).

When the key 1 is inserted and rotated in the unlocked state, the key disk 45 is rotated differently according to the difference of the step surface formed in the key 1, and the rotation of the key disk 45 is locked. The portion 452 is constrained by the cylinder 43 to be rotated within a certain angle range, and the rotation is prohibited beyond that. At the same time, as the inner cylinder 4 is rotated, the locking ring (not shown) attached to the rear portion of the inner cylinder 4 is rotated to be engaged with the latch (not shown), thereby locking.

In addition, as the key disk 45 rotates with the rotation of the inner cylinder 4, the positions of the locking pin grooves 453 that are aligned in line with the locking pin seating grooves 21 of the outer cylinder 2 are aligned. As it is changed, the locking pin 5 seated in the locking pin grooves 453 and 443 is pushed down, and in this state, the locking pin groove 435 of the cylinder 43 of the inner cylinder 4 is the outer cylinder (2). When it comes on the locking pin seating groove 21 of the, as shown in Figure 10, the locking pin 5 is seated in the locking pin seating groove 21 of the outer cylinder 2, the locking pin (5) Rotation of the inner cylinder 4 is prohibited.

On the other hand, if you lose the key (1) will not be able to open the lock, so to prevent this to prepare a master key (not shown), to prepare a key disk so that all the lock can be opened and locked with one master key The key hole 451 of 45 has a structure in which a groove corresponding to the step surface of the master key is additionally formed.
