Description

Disk tumbler type lock device {LOCK ASSEMBLY OF DISK-TUMBLER TYPE}

The present invention is to press the disc tumbler inserted in the radial direction of the inner cylinder with a compression coil spring so that the lock fixing end is engaged with the inner peripheral surface receiving portion of the outer cylinder, the key tumbler of the key plate inserted into the through hole of the disk tumbler The disc tumbler type lock device which immersed the lock fixed end of a disc tumbler by the inside cylinder side by this.

[Prior art]

In the disc tumbler lock device disclosed in Japanese Unexamined Patent Publication No. 2-210176, it is orthogonal to the moving direction of the tumbler and the insertion direction of the key along the opening edge 10 of the pressing side of the key insertion hole in each tumbler. The rotating body which has the rotation center to be arrange | positioned is comprised.

In this disc tumbler type lock device, when the key is inserted into or pulled out of the key insertion hole, the side surface of the key rotates the rotating body through the key insertion hole and simultaneously presses the tumbler through the rotating body. It can be moved in the outer cylinder direction, and the whole component including the main parts such as the outer cylinder and the inner cylinder is a press-worked product, and since the number of parts is large, the manufacturing cost increases and the assembly work is complicated, thereby reducing the assembly cost. It was not easy. In addition, since the press-worked parts are assembled by inserting and tightening and fixing, the mechanical strength is also weak, the resistance to violent destruction, and there is a problem in that the rotating shaft, which is a key component, is destroyed by repeated unlocking operation.

Accordingly, an object of the present invention is to provide a disk tumble lock device which can perform assembly with high mechanical strength while reducing the number of parts and reducing the production cost by making the main components die-cast. have.
