Description

A safe device for drawer open and shut part of the small cash box}

The present invention relates to a drawer opening and closing device for a small safe, more specifically, a small gold that provides convenience and safety because it is automatically controlled by the stationary motor by the keypad operation in addition to the key operation to lock or unlock the drawer. Relates to an employment drawer switchgear.

In general, the small safe is used simply for cash storage in small stores, chain stores, such as shops and restaurants.

The small safe is configured to draw the drawer back and forth from the front of the main body, the front of the drawer is provided with a key bundle and an operation button.

That is, after releasing the lock state of the drawer by inserting and operating a key into the key bundle, the operation button is operated so that the drawer is pulled out and operated by the ejection means normally installed on the back of the drawer.

However, the conventional small safe has a problem that its use is very inconvenient because the drawer locks or unlocks only by a key operation.

In particular, there is a problem in that it is difficult to unlock the drawer when the key is lost or not carried.

In addition, since the drawer is locked or unlocked by the key operation as described above, there is a problem in that reliability is lowered in terms of safety.

The present invention has been devised to solve the above problems of the prior art, and the lock or unlock operation of the drawer is automatically controlled by the stationary motor by the keypad operation in addition to the key operation to provide convenience and safety excellently. There is this.

This invention,

Press the drawer to form a key bundle on the front of the main body by pressing the push button of the operation plate on the back of the moving movement is used to pull out the front, on the one side of the operation plate and the reverse and reverse drive operation of the forward and reverse drive keypad operation And an eccentric cam shaft installed on the motor shaft of the stationary motor, and an eccentric cam shaft is inserted into a guide hole formed at a rear end of the operating lever arranged to be rotatable with a rotating shaft to operate the cam by the cam of the eccentric cam shaft. Rotate up and down to support or release the operating plate is characterized in that the operation.

The sensing lever is bent at the tip of the operating lever of the present invention, and the sensing end is characterized in that the operating lever detects the vertical rotation position of the support plate or the support release state by the upper and lower sensing sensors.

The operating plate of the present invention forms a through hole on one side, and installs an inclined operating surface of one side of the operating protrusion protruding on the back of the push button as the through hole, so that the inclined operating surface is pushed to the side by pressing the push button. It is characterized by the bullet movement.

The present invention achieves the locking or unlocking operation of the drawer by automatically operating the forward and reverse rotation of the lever by the forward and reverse motor by the keypad operation in addition to the key operation, and by simply pressing the push button to draw out the drawer. Compared to operating with a key operation, it has the effect of providing excellent convenience and safety.

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

The drawer opening and closing device for the small safe of the present invention is as shown in FIGS.

In using the drawer 3 which forms the key bundle 5 in the front of the main body 2, the push-button 6 pushes forward, and the operation plate 10 of the back is pulled out and used in the forward movement.

On one side of the operation plate 10 is installed and configured a forward and reverse motor (M) for forward and reverse driving operation by operating the keypad 20 of the front of the drawer, and an eccentric cam shaft 31 is installed on the motor shaft of the forward and reverse motor,

The eccentric camshaft 31 is inserted with a guide hole 36 formed at the rear end of the actuating lever 35, the center of which is rotatably formed by the rotating shaft 32, thereby rotating the actuating lever up and down by the cam operation of the eccentric camshaft. The operating plate 10 is made to support or release support.

In this case, the sensing end 37 is bent at the tip of the actuating lever 35, and the sensing end detects the vertical rotation position of the actuating lever 35 supporting or releasing the operating plate 10. Configured to be sensed by sensors S1 and S2.

In addition, the operation plate 10 forms a through hole 12 on one side, and inserts and installs one side inclined operation surface 41 of the operation protrusion 40 protruding from the back of the push button into the through hole 12. The inclined operating surface is configured to move the operating plate 10 sideways by pushing the push button.

At this time, the rear side of the drawer (3) is provided with a normal bullet extraction means (not shown) is configured to pull out the drawer forward forward as the operation plate is moved to the side shot.

One side of the operation plate 10 is configured to support or release the operation plate by the operation lever 50 of the key bundle 5 by the rotation operation.

In addition, the keypad 20 has a built-in PCB for controlling the stationary motor (M) and the up and down sensor (S1) (S2).

As the reference numeral 19, 19 denotes a support pin for supporting the operating plate, and 60 denotes an elastic spring for impacting the operating plate 10.

Next, look at the operation and action of the subject innovation configured as described above.

The small safe of the present invention is an automatic lock or unlock operation by a keypad operation in addition to a key operation.

In more detail, first, the keypad 20 on the front of the drawer is operated.

For example, by pressing the set password 777 button, the control unit (not shown) rotates the eccentric cam shaft 31 installed in the motor shaft together with the motor shaft of the stationary motor M.

Since the guide hole 36 of the rear end of the operating lever 35 is inserted into the eccentric cam shaft 31 which is rotated in this manner, the operating lever 35 rotates about the central rotating shaft 32 and the tip of the operating lever 35. The operation plate 10 is to be released in a supporting state.

When the support state of the operation plate 10 is released by rotating the operation lever 35 by the keypad operation as described above, the push button 6 is pressed.

At this time, one side inclined operating surface 41 of the operating protrusion 40 protruding from the back of the push button 6 pushes the through-hole 12 of the operating plate 10, the operating plate 10 in the lateral direction It will be moved.

As the operation plate is moved to the side in this way, the drawer 3 is to be pulled out to the front by the bullet extraction means (not shown) on the back.

After the drawer 3 is taken out and used in this manner, the drawer 3 is pushed back to its original position by pushing the drawer 3.

And to lock the drawer 3 again, the keypad 20 on the front of the drawer is operated.

For example, as the set password 777 button and the lock button are pressed in turn, the control unit (not shown) operates the eccentric cam shaft 31 installed in the motor shaft together with the motor shaft of the reverse motor M in reverse rotation.

Since the guide hole 36 at the rear end of the operating lever 35 is inserted into the eccentric cam shaft 31 which is operated in the reverse rotation, the operating lever 35 operates while being reversely rotated about the central rotation shaft 32. The tip of the lever is to operate the operation plate 10 from the released state to the support state again.

On the other hand, when the forward and reverse rotation of the operating lever 35, the detection stage 37 formed at the front end of the operating lever bent forward, reverse with the forward and reverse rotation of the operating lever up, down sensor (S1) (S2) is detected by the control unit will be able to accurately control the vertical rotation of the operating lever.

In addition, the locking or unlocking operation of the drawer can be achieved because the key is operated by inserting the key into the key bundle 5 as well as the above-described keypad operation.
