Description

Dial type lock with password change

The present invention relates to a dial-type lock capable of changing a password, and more particularly, to invent reliability and merchantability by changing to a password number selected by a user with a relatively simple operation.

In general, a dial lock that has been used in the related art is assigned a password for a dial in the manufacturing process, and once the password is designated, a user cannot arbitrarily change the dial.

Therefore, if the password of the dial is leaked to another person, the lock has to be replaced, which has a drawback that puts an economic burden on the user.

In order to secure these shortcomings, some password replacement locks have been developed, but the internal structure is complicated, making it difficult to manufacture and expensive.

In addition, it was cumbersome to replace the password, and the user had to suffer inconvenience during use.

1 is a view showing a method of exchanging a password for a conventional lock.

That is, when you want to change each number of the dial (2), when the lock is open, insert the external pressing tool (5) into the hole (1) or install it around the hole and press the cylinder (3) at the top to press the bottom. Each cylinder 3 is lowered while the spring 6 provided at the lower side of the negative cylinder 3 is compressed.

Accordingly, the locking grooves 4 recessed in the locking grooves 7 are uniformly descended from the locking grooves 7 and idling, so that the cylinder 3 and the dial 2 are individually operated, and thus are fixed. The numeric location of the password can be changed.

Then, when the upper cylinder 3 pressed by the external tool 5 is released, the spring 6 of the compressed bottom part is lifted and coupled to each cylinder 3 by the elastic force, so that the number of each dial is different from the first. .

However, the above-described conventional lock is unable to exchange numbers when there is no external pressing tool around to compress each spring to lower each cylinder by compressing the spring provided on the lower side of the cylinder.

There is a problem in that the password exchange operation is cumbersome because the number exchange operation is performed simultaneously with pressing the spring located on the bottom surface using this external pressing tool.

In addition, the conventional dial-type lock has an economical problem due to the difficulty in manufacturing and the increase in material cost due to the complicated configuration inside.

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

The dial-type lock capable of changing the password of the present invention shown in FIGS. 2 to 10 sets a password after the first lock is purchased, or if a password change is required while in use, a password state already set by simply pressing the lock 20 It was invented to be able to select a new number and then release it.

The configuration of the present invention for this function is the body 10, the clamp 20, the stopper 30 and the stopper pin 50 and the shaft 60, the dial 70, the memo ring 80, the rotating member 90 It is operated by the main components made of ).

That is, the body 10 is molded into two parts so as to accommodate a plurality of parts to be described later into the hollow inside of a metal material, and these parts are assembled and fastened to one body.

The fastening method of the body 10 is a riveting method of forming the head by hitting the end portion of the coupling pin 12 after the coupling pin 12 is fitted through the pin holes 11 formed on one side. Will be signed.

Therefore, after the assembly of the lock is completed, it cannot be disassembled using a tool or the like.

The body 10 is provided with a clasp 20 so as to be movable up and down, but the clasp 20 is bent in a U shape, so that one end is equipped with a clasp 21, and the other end is formed with a clasp ( 23) is formed of a shaft portion 22, and the locking groove 23 is provided at regular intervals on the shaft portion 22, the longitudinal direction of the shaft portion 22, that is, a hook that is one end of the latch 20 bent in the U shape It is provided in a position facing the (21), so that one end of the stopper 30, which will be described later, comes into contact with the locking groove 23.

The clamp 20 is a metal material having excellent strength, and substantially performs a locking function. When the selected passwords are matched, the shaft portion 22 has several hooks to be withdrawn from the body 10 and unlocked. The grooves 23 are dug.

The locking grooves 23 are respectively dug at positions corresponding to the stoppers 30 in a ratchet shape in which the upper part is horizontal and the lower part is inclined.

The stopper 30 is installed to be able to slide left and right to a position corresponding to the locking grooves 23 horizontally inside the body 10 in a plate shape of a predetermined thickness.

And, in the center, the long hole 31 is drilled at a central interval corresponding to the length of the left and right slides of the stopper 30 so that the upper cylindrical portion of the memo ring 80 can be fitted.

The stopper 30 is elastically supported in the direction of the locking groove 23 by the springs 40 installed on one side, so that the password is released and the external force is not applied, so that the stopper 30 is engaged by the stoppers 30 It will keep in contact with the grooves 23.

In addition, a stopper pin 50 is fixed to the stopper 30 toward the top.

The stopper pin 50 is vertically fixed to one side of the long hole 31 and slides together with the stopper 30.

When the password number is matched by the user's operation, it is applicable when the positions of the receiving grooves 82 and the stopper pins 50 dug in the memo ring 80 match, and thus the stopper pins through the receiving grooves 82 50 and the stopper 30 can be moved at the same time, it is possible to release the locking mechanism (20). (Fig. 11a)

When the lock is released due to the coincidence, when the latch 20 is pulled and moved, the inclined surface of the latch-shaped locking grooves 23 dug in the shaft 22 pushes the stopper 30 while the hook 21 is the body 10 ) Is unlocked while being separated from the stopper pin 50 of the stopper 30 toward the receiving groove 82 side of the memo ring 80 placed on the long hole 31 of each stopper 30. ), so that the stopper 30 once contacted with the locking groove 23 provided in the shaft 22 of the locking mechanism 20 is pulled to the upper side of the locking groove 20 when the locking mechanism 20 is pulled upward. Since it can be moved to the left side in the drawing by the inclined surface, the hook 21 of the clamp 20 is released from the lock hole 16 of the body 10, and the lock state of the lock is released.

And, for example, in a state where the number displayed on each dial 70 does not match the set password number, all or at least one password number among the four dials 70 and the memo ring 80 shown in the drawing Will not match.

At this time, the position of the receiving groove 82 dug in the memo ring 80 is shifted in a different direction from the moving position of the stopper pin 50.

Therefore, since the receiving groove 82 of the memo ring 80 accommodating the stopper pin 50 of the stopper 30 is misaligned, the stopper 30 cannot move to the left in the drawing, so the stopper 30 is a locking groove ( 23) to maintain a locked state to maintain a locked state in which the operation of withdrawal of the clamp 20 from the body 10 is impossible, wherein the locked state is maintained by the dials 70 and the memo ring 80 Since it is integrally rotated by the fitting groove 71 and the key projection 81 and rotates in the same way, when the passwords of the dials 70 made up of multiple stages do not match, the receiving groove provided at the bottom of each memoring 80 (82) means that the stopper pin (50) of the stopper (30) cannot be accommodated, and it is unable to move vertically by the stopper (30) to which the stopper (20) cannot move, thus forming a locked state. .

On the other hand, a rotating member 90 is centered on the hinge pin 91 at the lower end of the shaft 60 installed to penetrate the center of each memo ring 80 to manipulate the memo ring 80 to change the password setting. It is installed to rotate left and right.

The shaft 60 is installed vertically through the through hole of the long hole 31 and the memo ring 80 of the stopper 30 and the through hole of the dial 70 installed sequentially stacked inside the body 10. In the lower part, an annular support frame 61 in contact with a lower surface of the stacked memo ring 80 is integrally provided.

The memo rings 80 sequentially stacked on the support frame 61 as described above, the shaft 60 is raised as the rotating member 90 is rotated, and is in contact with the support frame 61 of the shaft 60. The memorings 80 also rise in the same way.

The dial 70 is a cap-shaped cross section that is open toward the bottom, and numbers for password setting are formed around the periphery, and the fitting grooves 71 are radially dug along the circumferential surface in the center.

The memo ring 80 is installed in succession to the shaft 60 in a state located on each upper surface of the stoppers 30, and a key projection 81 to be caught in the fitting groove 71 of the dial 70 at the upper portion ) Is integrally molded.

And, the lower portion of the memo ring 80 is provided with a receiving groove 82 that can receive the stopper pin 50 of the stopper 30 at the same vertical position as the key projection 81.

The rotating member 90 is axially installed on the body 10 so as to be rotatable around the hinge pin 91, and one side (left in FIG. 5) has a shaft 60 in contact with the upper side, and the other side (in FIG. 5). The right side) is installed in a structure in which the arms are symmetrically extended to both sides to the position of the lower end of the shaft 20 of the clamp 20.

The rotating member 90 and the shaft 60 are operated when the password setting is to be changed, which will be described in detail.

The dial 70 is stacked inside the body 10 to form a part of which is exposed to the outside of the body 10. At this time, when the passwords of the respective dials 70 match, the latch 20 The hook 21 of the body 10 is in an unlocked state that can rise from the lock hole 16 of the body 10. (Virtual line in FIG. 7)

As described above, the hook 21 deviated from the lock hole 16 of the body 10 can be rotated by using the shaft 22 of the clamp 20 as a rotation axis, so that the rotation angle is 90 degrees or more regardless of the horizontal direction. Rotate, but preferably, the rotation angle is preferably rotated close to 180 degrees (solid line in FIG. 8).

Subsequently, when the clamp 20 is pressed in the vertical direction, the lower end of the shaft 23 pushes the right side of the rotating member 90, so that the rotating member 90 rotates with the hinge pin 91 as the central axis. By doing so, the shaft 60 in contact with the left end of the rotating member 90 is raised (FIG. 9).

When the shaft 60 is raised, the multi-stage memorings 80 stacked by the support frame 61 of the shaft 60 are raised, and the key projections 81 of the raised memories 80 are raised. Is deviated from the fitting groove 71 of each dial 70 so that each dial 70 is rotatable.

The respective dials 70 are rotatable, as shown in FIG. 11B, the stopper pin 50 is maintained in the receiving groove 82 of the memo ring 80, and only the memo ring 80 is maintained. Since the key projection 81 of the dial is released from the fitting groove 71 of the dial 70, it is possible to rotate the dial 70.

Therefore, after the user rotates and changes each dial 70 sequentially with a desired password number, when the pressure pressing the latch 20 is released, the shaft 60 rises and compresses the return spring 100. The shaft 60 is lowered by the restoring force, and as a result, the clamp 21 is raised, and the memorings 80 are the same as the shaft 60 is lowered, while the key projection 81 is dialed with a number ( At the position of 70), the fitting groove 71 is formed again.

The password setting is completed as the stopper pin 50 is allowed to be accommodated in the receiving groove 82 only at the changed password number position by the operation sequence.

The return spring 100 is resiliently installed on the upper portion of the shaft 60 so that the shaft 60 is returned to its original position toward the lower portion when the rotating member 90 is returned.

In addition, the inner lower portion of the body 10 is equipped with a support portion 15 for maintaining the rotating member 90 made of both wings axially coupled to be rotatable by a hinge pin 91 in a horizontal state. (15) is to support the one side wing (left side in the drawing) of the rotating member 90, the rotation range of the rotating member 90 by the elastic force of the return spring 100 supported on the upper part of the shaft 60 Control.

Meanwhile, an inclined portion 25 is formed at a lower end of the shaft portion 22 of the clamp 20.

As shown in FIG. 8, the inclined portion 25 may be in a position where the stopper 30 positioned at the lowermost portion in a position just before the shaft portion 22 of the clamp 20 is lowered is not in contact with the shaft portion 22 When is lowered, this stopper 30 can be completely moved while being in contact with the inclined surface 25.

In addition, the body 10 is integrally formed with a control projection 13 for controlling the descending position of the hook 21.

Then, the waist groove 24 is formed on the upper portion of the shaft portion 22 of the locking mechanism 20, and the body 10 is blocked to prevent the separation of the locking mechanism 20 by being caught in the waist groove 24. The projection 14 is integrally molded.

After the password is changed as described above, when the passwords of the numbers indicated by the circumferences of the respective dials 70 match, the catch 20 is unlocked from the body 10.

On the other hand, the inside of the body 10 is provided with a leaf spring (1) in contact with each dial (70) to have a click feeling.

In the above, the present invention has been described in detail only with respect to the described specific examples, but it is apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and it is obvious that such modifications and modifications belong to the appended claims. will be.
