In addition, one side wall and the key body is provided with a protrusion protrusion; An actuating lever having a catching groove corresponding to the catching protrusion formed at an upper end thereof to move up and down according to the rotation of the key body; A pin support which is flowed in a horizontal direction in association with a lifting operation of the operation lever, and a pin support coupled to an inserting groove formed at an end of the inner rotation body at a distal end thereof; In the pin support is characterized in that the pressing spring for pressing and supporting the confirmation pin with an elastic force.

This invention, in the state that the confirmation pin and the support that can check the password of the dial key when the password is integrally mounted in the dial key housing, the administrator can quickly find out the password using the master key of the locker Management efficiency can be improved.

In particular, it is possible to prevent the risk of loss because it is integrally mounted in the housing without storing the password verification means separately.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the overall structure of the dial key type locking device according to the present embodiment will be described with reference to FIG. 1. In the locking device housing 1, a plurality of dials 11 and internal rotating bodies 12 are formed on the shaft shaft 10. It is provided in a stacked form to be inserted in, the upper end of the shaft shaft 10 is provided with a latch fitting connector 20, which is connected to the rear end side.

As shown in FIG. 2, each of the inner rotary bodies 12 has an insertion groove 12a formed in one lower wall thereof, and an inner circumferential surface thereof so as to correspond to the protruding key 10a of the shaft shaft 10. 12b) is formed, and the convex-convex protrusions 12c are formed along the upper circumference thereof, so that the dial 11 can be configured to be engaged with the inner circumferential surface, and the dial locking device is well known. Description of the detailed construction will be omitted since it is a technology.

On the other hand, the keying body 30 is rotated by the master key is mounted inside the hook connector 20, the locking body 31 is protruded on one side of the key body 30, the locking to correspond to this The operating lever 40 formed in the upper end of the groove 41 is configured to be movable up and down.

In addition, each of the inner rotating body 12 is coupled to the pin support 50 while the check pin 51 is elastically supported by the pressure spring 52 so as to be selectively inserted into the insertion groove 12a at a corresponding position. Although it is configured, the pin support (50) is provided with a pressing protrusion (53) protruding on the back, the operating lever 40 corresponding to this has a seating groove 43 is formed in accordance with the lifting operation of the operating reb (40) It was configured to flow the pin support 50 in the front and rear direction. The front side of the pin support 50 is provided with a restoring spring 54 for returning it to its original position in the forward state.

In the drawings, reference numeral 2 denotes a fixing ring fixed to the door side, and 32 denotes a key groove for key insertion.

Let us look at the process of confirming the loss of the dial password of the present invention locking device constituting such a configuration.

Locking device of the present invention is usually installed on the door (D) of the locker or locker is controlled to open and close by the clasp 21, the locking bar 100 is to be caught on the locker body side Will be installed.

If the user forgets the password in the course of use, the administrator can notify the administrator, and the administrator can check the password of each dial 11 using the master key for management.

That is, when the master key is inserted into the key groove 32 and then rotated clockwise, the locking lever 31 is rotated, and thus the operating lever 40 is lowered as shown in FIG. 3A. As the pressing protrusion 53 of the pin support 50, which is located in the seating groove 43 of (), is pushed, the entire pin support 50 is shifted to the left.

Accordingly, the pressing force is applied to each of the check pins 51, but only the pressure spring 52 is in a contracted state because it is blocked by the outer wall of the inner rotor 12.

In this state, when each dial 11 is slowly rotated, the internal rotating body 12 is rotated together with the dial 11, and in this process, the insertion groove 12a is connected to the check pin 51. When it reaches a corresponding position, the corresponding confirmation pin 51 is inserted into the insertion groove 12a due to the pressing force of the pressing spring 52.

Therefore, when each dial 11 is rotated, as shown in FIG. 3B by the respective confirmation pin 51 at the preset password position, the dial 11 no longer rotates, thereby easily confirming all the passwords. Will be.

As such, when the positions of the insertion grooves 12a and the confirmation pins 51 coincide with each other, the key grooves 12b of each of the internal rotating bodies 12 also have the protruding keys 10a of the shaft shaft 10. Since the state of the shaft shaft 10 can be made to flow, and as shown in FIG. 4, when the user turns the entire housing 1 as shown in FIG. 4, the top of the shaft shaft 10 is fixed in the rotation process. It can be seen that the door (D) can be opened by being released while being pushed down by the locking jaw of the ring (2) and the locking state between the catching clasp (21) and the locking bar (100).

On the other hand, after confirming the password as described above, if the master key is returned to the original position again, the operation lever 40 is raised while the pressing force on the pin support 50 and the pressing protrusion 53 is released. Due to the elastic force of the restoring spring 54, the pin support 50 is retracted to the right, so that the confirmation pin 51 inserted into the insertion groove 12a is pulled out so that the locking state of the dial 11 is released. Will be.

Therefore, it can be seen that through the internal structure of the present invention it is possible to quickly and easily verify the password with only one master key when the password is lost.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the dial key locking device of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the door opening and closing control structure by the latch 21 and the locking bar 100 has been described and illustrated, but the locking type may adopt another method as necessary.

Therefore, such modified embodiments should not be understood individually from the spirit or scope of the present invention, such modified embodiments will be included within the appended utility model registration claims of the present invention.
