Description

Dial lock with easy reset

The present invention relates to a dial lock, and in particular, by simply rotating the knob for operating the ruler of the dial lock to the reset position instead of the lock or open position, the password is reset on the dial plate. A dial lock is easy to reset.

In general, a lock that rotates (moves) a pivotal piece with a knob is used for doors as well as various furniture (locks, cabinets, drawers, and filing cabinets). There is a dial lock using a bundle.

The key lock can be locked and unlocked only if each individual carries the key at all times. If the key is lost, the key lock cannot be locked and unlocked. There is a lot of problems of theft because it requires a lot of maintenance costs, and if there is a separate tool such as a universal pin can open the lock effortlessly.

On the other hand, the dial lock can be locked and unlocked by simply adjusting the dial of the dial according to the set password, so you do not need to carry the keys one by one, and the password can be reset at any time and used as a universal pin. It is not easy to open, so there is little risk of theft, so I now prefer dial locks.

As a result, dial locks are widely used in iron and wood furniture (locks, cabinets, drawers, filing cabinets).

By the way, the existing dial lock has a complicated and cumbersome reset process for the user to reset the password, so that users feel a difficulty in using.

For example, there is a "dial lock reset device" registered in Korean Patent No. 10-0558118 (registered on February 28, 2006).

The reset device is provided with a separate reset groove in the rotor of the dial lock, and the reset groove has a spring and a reset bundle provided with a button and a guide projection on the front and one side to spring back to press the button to reverse the reset bundle Only when the rotor is configured to move to the "reset" position.

In addition, the inside of the rotor is a key bundle that is operated by the master key is installed so that the key bundle and the rotor is rotated to the "open", "close", "reset" position by the lever (knob).

In other words, the prior invention has to always press the button of the reset bundle to reset the password, so that the free state of the rotor can be moved to the "reset" position since the guide bundle is inserted into the rotor while the reset bundle is reversed. It is.

However, when the protrusion of the reset bundle protrudes outward from the front plate on which the lever (knob) is installed, the protrusion of the reset bundle tends to be easily pressed when the dial or the lever is operated.

Therefore, the protrusions of the reset bundle are mostly installed without protruding from the front panel, which causes the user to use a tool such as a pin to rotate the lever (knob) to the "reset" position to reset the password. There is this.

In other words, in order to reset the password, you must first press the protrusion of the reset bundle, and the lever (knob) must be moved to the "reset" position while maintaining the state of pressing the protrusion.

The present invention was developed to solve the above-mentioned conventional problems, and an object of the present invention is to move the knob for operating the locking piece of the dial lock to the "reset" position immediately without the operation of the reset button in the "open" position. It provides an easy-to-reset dial lock that can be used to easily reset the password of the reset dial plate.

Another object of the present invention is to provide a dial lock that can be reset more precisely, the operation of which is stable, and the installation angle can be varied between the two wheels.

The present invention provides a dial lock attached to the surface of the drawer or the door to achieve the above object, the knob ball is provided on one side of the dial ball, the knob ball one side wall body is formed with a protrusion entrance toward the dial hole; A cam shaft fitted to a knob hole at a rear surface thereof, and a knob having a closed groove, an open groove, a reset portion, and a stop portion formed at an outer circumferential surface of the cam shaft; A dial shaft which is installed across the dial holes on the back of the main body, and has a key protrusion release portion in the form of a groove between one of the plurality of key protrusions formed at regular intervals; It is fitted to the dial shaft to be moved toward the camshaft under tension of the spring, and rotation is controlled when the key groove formed at one end of the inner circumferential surface is inserted into the key protrusion, and is freely rotated when placed at the position of the key release release part. Formed dial plate inner ring; A ring-shaped dial plate which is formed only at the center of the inner circumferential surface of the gear portion engaged with the locking protrusion and is coupled to the outer circumferential surface of the dial plate so that the locking protrusion rotates alone when the locking protrusion is out of the gear portion; A slider which forms a key groove on one side of the shaft hole fitted to the front end of the dial shaft and receives a spring tension and a protrusion of the other end selectively contacts the closing groove, the opening groove and the reset part of the cam shaft; Characterized in that consisting of.

In addition, the outer surface of the dial plate is provided with a concave-convex graduation portion having a larger diameter than the dial number part, so that the dial plate can be rotated quickly and accurately, and a guide protrusion for pushing the slider is formed on the inner surface of the cover plate so that the slider can be stably operated. Can be.

As described above, the present invention merely rotates the knob from the "open" position to the "reset" position when the user wants to change the password, and frees the dial plates while the key grooves of the inner ring of the dial are aligned with the key protrusion of the dial shaft. Since it can be rotated, the reset process and password setting process are very quick and easy.

In addition, the dial plate can be rotated more precisely by the irregularities of the diameter larger than the dial number of the dial plate, so that the operation of the dial lock is quick and accurate, and the operation of the slider operated in conjunction with the cam shaft of the knob is stable. , The installation angle between the ruler to be installed on the cam shaft can be installed in a variety of ways depending on the type of furniture or the structure of the door.

Hereinafter will be described in detail with reference to the accompanying drawings as a preferred embodiment the technical configuration and effect that can effectively achieve the features of the present invention.

1 is a perspective view illustrating a state in which a dial lock of the present invention is implemented in a drawer, FIG. 2 is a perspective view showing an embodiment of the dial lock of the present invention, and FIG. 3 is a part structure by separating the dial lock of the present invention. Is a perspective view.

As shown in the drawing, attached to the surface of the drawer or the door, if the set password can be adjusted to rotate the ruler interval 50 on the back side, the locking jaw (12a) (12b) in configuring the lock, The knob hole 11 provided at both ends is provided at one side of the plurality of dial balls 14, and the main body 10 is formed at one side wall of the knob ball 11 toward the dial hole 14 toward the dial hole 14. ).

And, the knob 30 is inserted into the knob hole 11, the cam shaft 40 is provided on the rear surface, the outer groove of the cam shaft 40, the deepest closing groove 41 and the opening groove 42 of the medium depth. ) And the reset portion 43 and the stop portions 44 alternately fastened to both of the locking jaws 12a and 12b are formed step by step, and the regular interval 50 is integrally fastened to the end of the cam shaft 40. .

On one side of the dial shaft 20 which is installed across the dial holes 14 on the rear surface of the main body 10, a key protrusion release portion having a groove portion is formed between a plurality of key protrusions 21 formed in a straight line at regular intervals ( 22) is formed.

The dial plate inner ring 60 fitted to the dial shaft 20 to elastically move toward the cam shaft 40 under tension of the spring 64 has a key groove 61 formed at one end of the inner circumferential surface of the key protrusion 21. Rotation is controlled when it is fitted and is rotated freely when placed in the key release release portion 22, a plurality of engaging projections 63 are formed at regular intervals on the inside of the flange 62 on the other end.

The plurality of ring-shaped dial plates 70 formed only in the center of the inner circumferential surface of the gear plate 71 engaged with the locking protrusion 63 of the inner ring 60 of the dial plate may be separated when the locking protrusion 63 is out of the gear portion 71. Is coupled to the outer circumferential surface of the dial plate inner ring 60 to rotate, a portion of the dial portion 72 of the outer circumferential surface is projected to the outside through the dial hole (14).

A slider 80 having a shaft hole 82 having a key groove 83 formed at one end thereof so as to be fitted to the front end of the dial shaft 20 has a spring 84 between the dial shaft 20 and the shaft hole 82. The outermost dial plate inner ring 60 and spaced apart a predetermined distance, the other end of the protrusion 81 is the closing groove 41 and the opening groove 42 of the cam shaft 40 through the protrusion entrance 13 And a selective contact with the reset section 43.

In the figure, reference numeral 31 is a reference point of the knob 30, 90 is a cover covering the back opening of the main body 10, 15 is the outer peripheral surface of the dial 72 of the dial plate 70 (16a) (16b) is formed on both sides of the main body 10 to maintain the state in which the main body 10 is coupled to the drawer or the door. It is a fastener.

In the present invention formed as described above, as shown in FIGS. 4A and 4B, the reference point 31 of the knob 30 is in the "closed" position, and the dial 72 exposed through the dial hole 14 has a number other than a password. If the key groove 61 of the dial plate inner ring 60 fitted to the dial shaft 20 is in the key protrusion release part 22 position, the key shaft 21 of the dial shaft 20 is out of alignment with the key protrusion 21 of the dial shaft 20. It is a state.

Therefore, in this state, even if the slider 80 presses the dial plate inner ring 60, the dial plate inner ring 60 is not pressed by the dial shaft 20. In this case, even if the knob 30 is to be rotated to the "open" position. Since the projection 81 of the slider 80 does not escape the closing groove 41, the knob 30 cannot be rotated.

That is, in order to rotate the knob 30 to the "open" position, the dial portion 72 of the dial plate 70, which is visible through the dial hole 14, must be adjusted with a password. Then, each of the key grooves 61 of the dial inner rings 60 is in the same line as the key protrusion 21 at the key protrusion release portion 22 position.

In this state, as shown in FIGS. 5A and 5B, when the knob 30 is turned to the “open” position, the slider 80 pressed by the cam shaft 40 moves toward the dial plate inner ring 60 when it exits the closing groove 41. Since the spaced portion is formed between the slider 80 and the outermost dial plate inner ring 60 at a predetermined interval, the slider 80 causes the dial plate inner ring 60 not to be operated or only slightly operated even if it is operated. do.

That is, since the gear part 71 of the inner circumferential surface of the dial plate 70 is formed at the center portion, and a predetermined space is secured to the upper and lower portions of the gear part 71, the respective inner circumferential surface of each dial plate 70 is intact. The flange 62 of the lateral dial plate inner ring 60 is slightly pushed into the space of, but the locking projection 63 is caught in the gear portion 71 of the dial plate 70.

In addition, since the key grooves 61 of the dial plate inner ring 60 are hung on the key protrusions 21, in this state, even if the key grooves 61 and the key protrusions 21 of the dial plate inner rings 60 are aligned, Since the plate 70 is not rotated, the password cannot be reset.

Therefore, the dial plates 70 are moved to the side along the straight key protrusion 21 so that only the respective inner dial plate inner rings 60 are pressed while they are not reset, and the " open " position of the knob 30 The rotation of the furnace is possible, and when the knob 30 is rotated to the "open" position, the regular interval 50 at the rear of the cam shaft 40 rotated along the knob 30 is in a unlocked state.

Then, when the movement of the “open” position of the knob 30 is completed, the protrusion 81 of the slider 80 that is shot under tension by the spring 84 is fitted into the opening groove 42 to stop the rotation of the knob 30. And, each of the dial plate inner ring 60 under the tension of the spring 64 is moved to the original position along the key protrusion 21 is placed back in the key protrusion release portion 22 position.

In this state, when the user wants to change the password, the user can reset the password simply by moving the knob 30 to the "reset" position as shown in 6a and 6b without having to press the reset button as in the prior art. have.

Here, the stop portion 44 of the camshaft 40 which is rotated integrally with the knob 30 when the knob 30 is rotated toward the "reset" is caught by the one side locking jaw 12a of the knob hole 11. Since it is not rotated, knob 30 is only rotated to the exact "reset" position.

In addition, the reset portion 43 of the knob 30 has a larger diameter than the closing groove 41 and the opening groove 42. Therefore, when the knob 30 is moved to the "reset" position, the reset portion 43 of the camshaft 40 presses the protrusion 81 of the slider 80 to the maximum, thereby compressing the spring 84. 80 will push the dial plate inner ring 60 as much as possible.

When the dial plate inner ring 60 is as described above, the locking projection 63 of the outer circumferential surface is out of the gear portion 71 of the inner circumferential surface of the dial plate 70, so that the dial plate inner ring 60 has the key groove 61 of the dial shaft 20. The dial plate 70 can be freely rotated in a state of being locked to the key protrusion 21 of.

In this state, the number of the dial 72 displayed through the dial hole 14 can be easily changed and set by a new password. After changing the password, the knob 30 is moved to the "open" position. As a result, the protrusion 81 of the slider 80 under tension of the spring 84 is quickly fitted into the "opening groove 42".

Then, the dial plate inner ring 60 pressed by the slider 80 is quickly returned to its original position under the tension of the spring 64, and the engaging projection 63 of the outer circumferential surface of the gear portion 71 of the inner circumferential surface of the dial plate 70 is rotated. Since it is to be re-engaged in the engagement with the dial plate 70, that is to be rotated integrally, that is, ready to lock, the reset process for password change and password change is very quick and easy.

The present invention is characterized in that the one side of the dial portion 72 of the outer circumferential surface of the dial plate 70 is provided with a concave-convex portion 73 having a larger diameter than the dial portion 72.

According to the above configuration, the dial plate 70 can be accurately rotated by using the uneven part 73 projecting more outward than the dial part 72 through the dial hole 14, so that the operation of the dial lock can be quickly and accurately. It is easy.

The present invention is characterized in that to form a guide protrusion 91 for pressing the slider 80 on the inner surface of the cover (90).

Then, even if only the lower end of the shaft hole 82 is fitted into the key protrusion 21 at the tip of the dial shaft 20, the slider 80 stably presses the upper end of the slider 80 so that the slider 80 is rotated. ) Can be moved more smoothly, and the slider 80 can be prevented from being separated from the protrusion entrance (13).

The present invention is a means for fastening the camshaft 40 and the hook 50 between the camshaft 40, the end of the camshaft 40 to form a polygonal coupling protrusion 45, the screw hole in the center of the coupling protrusion 45 46 is formed, and the support portion 51 on one side of the regular interval 50 forms a polygonal coupling hole 52 which is twice the number of the coupling protrusions 45 and is fixedly installed with a screw 53. do.

That is, when the coupling protrusion 45 is a quadrangular shape, the coupling hole 52 is an octagonal shape. If the coupling protrusion 45 is a five-sided shape, the coupling hole 52 may be formed in a ten angle shape.

When configured in this way using the coupling hole 52 made of a polygon of the support 51 coupled to the coupling protrusion 45 so that the center interval 50 is located at various angles on the right side, the center, or the left side of the camshaft 40. It is possible to adjust the installation angle of the ruler interval 50 as needed.
