(Embodiment of design)

In the illustrated embodiment, the lock case 35 is fitted to the outside of the outer cylinder 1, and is fixedly attached by the spring pin 36. An axial protrusion 38 on the inner surface of the lock case 35 is fitted into the axial groove 37 on the outer surface of the outer cylinder 1, and the lock case 35 is not rotatable with respect to the outer cylinder 1. . A receiving seat cylinder 39 is fitted to the lock case 35 to conceal the spring pin 36. The guard plate 40 is rotatably fitted in the front part of the outer cylinder 1, and the front keyhole 31 of the inner cylinder 4 is concealed. The guard plate 42 is provided with a key insertion hole 41. A key hole 42 penetrates the rear wall portion 15 of the inner cylinder 4.

The lock case 35 is inserted into the receiving hole 8 of the attachment panel 6 from the front side, and is fixed to the attachment panel 6 by a nut 46 screwed into the rear threaded portion 12. do. A linkage body 19 is fixedly attached to the rear portion of the inner cylinder 4 by a fixing attachment ring 32, and a fixed metal plate or a switch operating plate is connected to the linkage body 19 depending on the purpose.

The first disk tumbler 22 and the second disk tumbler 24 are prepared five by one, and the inner cylinder 4 is alternately inserted in the reverse direction.

Disc tumbler lock device of the present invention configured as described above, the outer cylinder 1, the inner cylinder 4, the set pin 7, the guide pin 20, the first spring 21, the first disk tumbler 22 And the second disc tumbler 24, the second spring 26, and the spacer plate 28, and since the number of parts is relatively small and the structure is simplified, the outer cylinder 1 and the tumbler receiver of the main components are also provided. Since the grooved inner cylinder 4 is made of die-cast, it can be fabricated and assembled at a lower cost than the conventional apparatus, and is also high in strength, thereby providing a lock having a high resistance to violent destruction.

The inner cylinder 4 is partitioned with a partition wall 43 to provide the tumbler receiving groove 5 in the axial direction, and a pair of left and right pin receiving holes 13 and 14 are provided in the front wall portion 11 of the inner cylinder 4. Then, a pair of left and right pin receiving holes 17 and 18 are provided in the rear wall portion 15 of the inner cylinder 4, and the guide pin 20 is inserted into one of the left and right pair of pin receiving holes 13 and 17. Since the set pin 7 is inserted into the pair of left and right pin receiving holes 14 and 18, the first disc tumbler 22 and the second disc tumbler 24 are inserted into the tumbler receiving groove 5. The direction of insertion is not limited to one direction, and various other keys can be produced by inserting a part or all of a plurality of disk tumblers by reversing left and right.

In addition, the first spring 21, the first disk tumbler 22, the second disk tumbler 24, and the second spring 26 are sequentially disposed in the spring receiving grooves 9 and 10 and the tumbler receiving grooves 5, respectively. After inserting into the die, the set pin 7 is pressed into the inner cylinder 4 while pressing the spring support protrusion 27 and the second spring 26 of the first disk tumbler 22 radially with the spacer plate 28. In the pin receiving holes (14, 18), the first spring (21) is compressed between the guide pin (20) and the spring support protrusion (27) of the first disk tumbler (22), and the second spring ( 26 is compressed between the spacer plate 28 which abuts on the set pin 7 and the spring support protrusion 29 of the second disk tumbler 24, so that anyone can easily and efficiently assemble the lock device. It is possible to do so, and the assembly cost can be reduced.
