[Detailed description of the invention] In this invention, when the cylindrical key is inserted into the circular keyhole on the front of the case, the locking pin slides in the axial direction of the operating shaft to unlock the rotating plug from the fixed plug. The present invention relates to a locking device, a so-called axial pin tumbler lock.

In conventional axial pin tumbler locks, when the operating shaft is returned to the locked position and rotated, the pin holes of the rotating plug and fixed plug are aligned in a straight line, and the spring force that biases the lock pin to slide forward is applied. Although it also acts on the cylindrical key via the lock pin, the elastic force of the spring is generally set weak to prevent wear on the lock pin, so it is insufficient to push the cylindrical key out of the keyhole. Therefore, it is necessary for the operator to actively remove the key himself, but if this removal operation is neglected, serious problems may occur depending on the application.

For example, assume that an axial pin tumbler lock is used as a lock portion of a key switch device, and the key switch device is used as a start control means for equipment such as a die-casting machine.

In order to inspect and maintain equipment, a worker turned the key back to the locked position, that is, the off position of the switch installed behind the lock, and stopped the equipment, but he skipped removing the key and started the inspection work. Let's say it's Tsuta. In such a case, another worker, who was behind the equipment and did not notice that the equipment was being inspected, accidentally turned the key that was still attached.
This sometimes causes the equipment to start, exposing workers during inspection to dangers such as being caught in the equipment that suddenly starts moving, or being hit by the equipment.

The cylindrical key 6 is inserted through the circular keyhole 12 on the front of the case against the bias of the spring 11, and the driven pin 10 and the driving pin 9 are slid backward to connect the contact point with the rotating plug 3. An operation step portion 13 is provided on the outer periphery of the end portion to match the shear line between the fixed plugs 2. The push-in protrusion 17 is constituted by a pin body having a slightly smaller diameter than the protrusion pin 15, and is driven into and fixed to the inner bottom surface of the cylindrical key 6.

A driving protrusion 24 is provided on the inner periphery of the end of the key 6 along its axis, and is inserted into an axial driven groove 25 provided on the outer periphery of the front end of the operating shaft 5 .
The inner peripheral surface of the keyhole 12 has an axial guide groove 2 on the outer peripheral surface of the key.
A retaining protrusion 28 that enters the annular groove 27 through the annular groove 6 is provided. When the key 6 rotates 90 degrees and comes to the unlocked position, that is, the on position of the switch 20, the protrusion 28 enters the recess 29 toward the tip of the key, and the key 6 and the operating shaft 5
prevents return rotation.

When the cylindrical key 6 is inserted into and removed from the circular keyhole 12, the driven pin 10 and the driving pin 9 slide back and forth, and the operating shaft 5 is unlocked and locked from the fixed plug 2, unlike the conventional axial direction. Although it is the same as a pin tumbler lock, in the present invention, an axial receiving hole 14 provided in the operating shaft 5 is used.
A protruding pin 15 is slidably accommodated in the cylindrical key 6, and the pin is urged forward by a strong spring 16. A push-in protrusion 17 is provided on the inner bottom surface of the cylindrical key 6 to protrude in the axial direction. When inserting into the circular keyhole 12 of the case 1, push the protruding pin 15 with the pin 17,
Since the spring 16 is compressed by the protruding pin 15 that has slid backward, when the key 6 is returned to the locked position and rotated to stop pressing the key, the key 6 is pushed forward due to the large elastic force of the spring 16. It is projected from the keyhole 12 by the sliding projecting pin 15.

In this way, once it is returned to the locked position,
Since the key is forcibly removed from the lock body and is not left inserted, for example, when the axial pin tumbler lock of the present invention is used as a locking mechanism for a key switch device for controlling the start of equipment, This greatly improves safety when inspecting and servicing equipment by stopping the system, and eliminates accidents resulting in death or injury to inspection workers due to unexpected resumption of operation.

Further, in the present invention, the spring 16 for protruding the key 6 is housed in the operating shaft 5, and is arranged so that the strong elastic force of the spring 16 does not act on the driving pin 9 or the driven pin 10. The present invention has great practical value, such as being able to accurately protect the lock pin from rapid wear.
