The present invention relates to a lock-type lock actuator of a safe type lock which can operate a lock bolt operating inward and outward through a radial channel in a cylinder in association with a dial key.

In the conventional safe type lock, the binding tank, which is operated inward and outward through the radially penetrated channel in the body, is correlated with the dial key installed therein, and the binding tank is complicated and there are many parts. Caused.

In the present invention, this defect is improved, and four spiral protrusions are formed on the rear side of the operation plate, which is constricted to the outer side of the dial rotating plate of the dial, so that they are engaged with the rear recessed end of the rockbolt inserted into the channel to fit the key rotating plate of the dial. When the lock arm is fixed to the operation plate by the groove in the upper part, the rear protruding part of the tip is lowered and the toenail of the tip is caught by the locking groove of the driving cap that is fixed to the end of the dial. Rockbott that is rotated at the same time and bound to the spiral protrusion is also to be operated at the same time according to the drawings in detail as follows.

When the key rotary plate 2 of the dial shaft 1 is aligned, the front toenail 11 of the lock arm 10, in which the rear protrusion piece 12 of the tip is operated downward by the groove formed in the upper part, is connected with the dial shaft. In the known safe type lock in which the operation plate 20 can be rotated at the same time, the lock bolt 5 inserted into the channel 4 is formed by forming a spiral protrusion 21 on the rear side of the operation plate to correspond to four radial channels. Binding to the rear recess of the end (5 ') of the helical projection between the one end of the projection forming end 22 to limit the rotation to the reference numeral 6 is a spring and (7) is a cover plate.

When locking the lock of the present invention having such a structure, when the dial rotates, the operation plate 20 is also driven by the lock arm 10 in which the claws 11 are caught in the locking grooves 3 'of the drive cam 3. At the same time, the lockbolt, which is bound to the spiral protrusion plate 21 of the operating plate, is operated outward by the rotation, and the rotation angle is limited by the limiting protrusion 22, and the lock is downward by the locking groove of the driving cam. The tip claw 11 of the arm is also lifted by the drive cam, and the rear protrusions 12 disengage the key rotary plates fixed to the grooves to completely lock each other. When unlocking the lock, rotate the dial shaft according to the dial number. When the groove is aligned with the upper part of the upper end, the rear protruding piece 12 of the leading toenail 11 that is raised falls into the groove and is downwardly caught by the locking groove of the driving cam 3 at the end of the dial shaft. production Rokbo plate is rotated at the same time that the dial shaft hanging the rear yaw joined 5 'protruding end of the spiral operating plate Baltic are downwardly will be pulrige the lock.

Claims (1)

When the key rotating plate 2 of the dial shaft 1 is aligned, the front claw 11 of the lock arm 10, in which the rear protrusion piece 12 of the tip is operated downward by the groove formed in the upper part, is the end of the dial shaft. In the well-known safe type lock in which the operating plate 20 can be rotated at the same time as the dial shaft and caught by the engaging groove 3 'of the driving cam 3 installed in the spirally projected end, corresponding to four radial channels on the rear side of the operating plate. (21) is formed to engage the rear recessed end (5 ') of the lock bolt (5) inserted into the channel (4), and a convex protrusion (22) is formed between one side of the spiral protrusion and the lid (7) Of the lock-type lock in which the safety pin 17 provided in the safety groove 9 is inserted into the safety device inlet end 5 "by the elastic force of the leaf spring 8 when it is broken and detached. Bolt actuator.
