TH170780B - Cylinder locking device - Google Patents

Abstract

A cylinder locking device is provided where the cylinder is inside. To be rotated around the axis into the cylindrical body, the guard will be placed. Opposite the end of the inner cylinder, along the insertion direction of the mechanical key. The guard can allow the mechanical key to be inserted into the inner cylinder, and the spring with A coiled shape is arranged between the bodyguard and the inner cylinder or the cylindrical body, where the spring (50) is formed to make the helical portion (50a) protruding in direction Along the axis of the inner cylinder (13) and the arc section (50b) being bent from at least Finally, one end piece of the coil portion (50a) approaches the inside of the coil section (50a) in the axial direction of the inner cylinder (13) .This can cause the spring deformation of the coil shape to That curl has been kept from happening.
