Description

Security lock

The present disclosure relates to a dial lock having improved security, and more particularly, to a dial lock having improved security for preventing a crime of inferring a password by recognizing a projection by a tolerance between the lock and the dial.

Unless otherwise indicated herein, the contents described in this identification are not prior art to the claims of this application and the description in this identification is not admitted to be prior art.

In general, a lock is a means for preventing theft of personal belongings or valuables and is used to prevent opening after closing a door or locker. Types of the lock include a key lock that can be opened and closed through a lock and a separate key, and a dial lock that can be opened and closed through a dial provided on the lock body without any other means.

Here, the conventional dial lock has a lock body portion 10, as shown in Figure 1, the hook-shaped latch portion 20 is inserted into the upper side of the main body portion 10, and the latch portion 20 of the A plurality of dials 30 are inserted into one side, and one long protrusion and a plurality of end protrusions are formed on the outside, and a clasp protrusion 47 is formed on the inner side, and the dial is located inside the dial part 30. It is composed of a gear portion 40 to rotate in engagement with the portion (30). Rotating the plurality of dials 30 while the combination of numbers coincides with the password, the lock is opened while the latch 20 is unlocked.

However, in the conventional dial lock as described above, there is a tolerance between the lock body portion 10 and the dial portion 30. When the dial is rotated through the tolerance, the dial lock is located inside the dial portion 30 to be engaged with the dial. There was a problem that the end of the long projection 41 formed on the outer surface of the rotating gear portion 40 can be recognized so that the password can be easily inferred. In addition, when the dial 30 is rotated in the state where the latch 20 is pulled upward, the latch protrusion 21 of the latch 20 is formed around the gear opening 40 within the gear 40. While rotating along the clasp groove 47, you can expect that the position of the corresponding dial matches the password with a certain sound, so if you do the same for all dials, you can infer the password as a result. As a result, there is a disadvantage that security is weak.

Improved security by providing a large number of recognizable protrusions on the outer side of the gear part through the tolerance between the lock body part and the dial part. In providing a dial lock.

In addition, the present invention is not limited to the above-described technical problems, and it is apparent that other technical problems may be derived from the following description.

A dial lock according to an embodiment of the present disclosure includes a lock main body portion, a hook-shaped latch portion inserted into an upper side of the main body portion, a plurality of dial portions inserted into one side of the latch portion, and one outside thereof. In the dial lock comprising a gear protrusion and a plurality of step projections are formed and a latch opening prevention jaw and a latch projection groove is formed on the inner side, and located inside the dial portion and engaged with the dial portion to rotate. The length of the formed protrusions is characterized in that the same as the length of the jangdol.

According to a preferred feature of the present disclosure, the gear portion is characterized in that a plurality of single layers are formed on the latch opening prevention jaw formed inside.

According to an embodiment of the present disclosure, the length of the plurality of protrusions is formed to be the same as the length of the long protrusion so that a plurality of protrusions recognizable from the tolerance between the lock main body part and the dial part may be present so that the password cannot be easily recognized. The advantage is that.

In addition, according to an embodiment of the present disclosure, when the dial is rotated while the latch portion is pulled upward, the inner portion of the gear portion may not be inferred by recognizing the groove from the point where the latch protrusion of the latch portion matches the latch protrusion groove of the gear portion. There is an advantage that the security is increased by having a plurality of monolayers formed in the.

The effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

For reference, in the drawings, each component is omitted or schematically illustrated for convenience and clarity, and the size of each component does not reflect the actual size. In addition, the same reference numerals throughout the specification refer to the same components and reference numerals for the same components in the individual drawings will be omitted.

1 is an exploded perspective view of a conventional dial lock, Figure 2 shows an exploded perspective view of a dial lock according to an embodiment of the present disclosure.

Dial lock 1 according to an embodiment of the present disclosure is a lock body portion 10, the hook-shaped latch portion 20 is inserted into the upper surface of the body portion 10, and the latch portion 20 A plurality of dial portion 30 is inserted into one side of the installation, and one long projection and a plurality of step projections are formed on the outside, the latch opening preventing jaw 45 and the latch projection groove 47 is formed on the inside, the dial portion (30) In the dial lock including a gear part 40 which is located inside and rotates in engagement with the dial part 30, the length of the step protrusion 43 formed on the outside of the gear part 40 is the long protrusion 41. It is characterized by being formed equal to the length of).

In the case of the conventional dial lock, as shown in FIG. 1, a latch lock hole 11 and a latch insertion hole 13 for inserting the hook-shaped latch portion 20 into the upper side of the lock body portion 10 are provided. Is formed. The clasp locking hole 11 has a short clasp inserted in the hook-shaped clasp 20 to perform a locking function, and the clasp insertion hole 13 has a long clasp at the clasp 20. The deep inside is inserted and is responsible for opening or closing the clasp 20 according to the rotation of the dial 30. In addition, the dial portion 30 is inserted into the main body portion on one side of the main body portion 10 to form a plurality of dial insertion grooves 15 to expose a portion of the dial, the plurality of dial insertion grooves 15 A dial support 17 for supporting the dial 30 is formed to intersect with each other.

The dial portion 30 is composed of a plurality of cylindrical openings formed in the center, it is inserted into the long latch of the latch portion (20). The outer side of the dial portion 30 is numbered, the groove is formed between each number is inserted into the body portion 10 by the elastic body 19 to control the rotation of the dial portion 30 by the dial portion 30 will rotate by one number. The inner side of the dial portion 30 is formed in a concave-convex shape, and grooves are formed in each of the positions corresponding to the respective numbers so that the dial portion is engaged with the projection of the groove portion and the gear portion 40 formed inside the dial portion 30. 30 and the gear unit 40 is rotated together.

The gear portion 40 is composed of a plurality of cylindrical openings formed in the center, the diameter is smaller than the dial portion 30 is inserted into the opening of the dial portion, the opening of the gear portion 40, the latch The long clasp of the part 20 is inserted through.

One long protrusion 41 and a plurality of step protrusions 43 are formed on the outer side of the gear part 40, and the latch opening preventing jaw 45 is formed on the inner center along the circumference of the inside of the gear protrusion 40. The clasp protrusion 47 is provided inside the position corresponding to 41. Therefore, when the password mismatch, a plurality of clasp protrusions 21 provided on the long clasp of the clasp 20 is caught by the clasp opening prevention jaw 45 so that the clasp is not opened, thereby rotating the dial part 30. Accordingly, when the clasp protrusion 47 and the clasp protrusion 21 are located on the same line and the passwords coincide with each other, the clasp is opened.

The main body portion 10 is formed with a dial insertion groove 15 into which the dial portion 30 is inserted, where a tolerance occurs between the dial insertion groove 15 and the dial portion 30 and the gear portion (between). The end of the long protrusion 41 of 40 is recognizable. Since the step protrusion 43 is shorter than the long protrusion 41 and is hidden by the dial part 30, the stepping protrusion 43 is not recognizable through a tolerance. Since it is exposed, the end of the long projection 41 can be recognized through the tolerance, and the long projection 41 is formed at a position corresponding to the clasp protrusion 47, so that the password can be inferred as a result.

3 shows a side view of a conventional gear portion and a gear portion according to an embodiment of the present disclosure, and FIG. 4 shows a cross-sectional perspective view of the gear portion in a dial lock according to an embodiment of the present disclosure.

In the dial lock 1 according to an embodiment of the present disclosure, the length of the plurality of step protrusions 43 provided on the outer side of the gear portion 40 is formed to be the same as the length of the long protrusion 41. It is characterized by. Dial portion by forming the length of the plurality of protrusions 43 to the same length as the length of the protrusions (41) in order to recognize the end of the Jangdol 41 through the tolerance so as not to infer the password (30) Since there are a plurality of protrusion ends exposed at the lower end, password induction according to the correspondence relationship between the long protrusion 41 and the latch protrusion 47 becomes difficult, thereby improving security. For example, when four long protrusions 41 are formed in one gear part 40, any one of four end ends of four long protrusions 41 is disposed outside the position corresponding to the clasp protrusion 47 through a tolerance. It is difficult to determine whether or not the formed projections 41 are formed, and thus the security is improved because the total number of four dials 30 has the number of 4x4x4x4 = 256.

In addition, in the case of the conventional dial lock 1, when the dial portion 30 is rotated while pulling the latch portion 20 upwards, the latch projection 21 of the latch portion 20 is inside the gear portion 40. While rotating along the circumference of the formed clasp opening brace 45, a password could be inferred by detecting a point coinciding with the clasp protrusion 47. Therefore, in the dial lock 1 according to an embodiment of the present disclosure, the gear portion 40 is characterized in that a plurality of single layer 49 is further formed inside. A plurality of the single layer 49 is formed on the latch opening preventing jaw 45 formed inside the gear portion 40, preferably, the single layer 49 is formed inside the position corresponding to the single protrusion 45. It is characterized by. As the plurality of monolayers 49 are formed in the gear unit 40, even when the dial unit 30 is rotated while pulling the clasp 20 upward, the monolayer 49 has a role similar to that of the clasp protrusion 47. Due to the 49, the feeling similar to the clasp groove 47 is sensed in the plurality of monolayers 49 in addition to the clasp groove 47, thereby preventing the password from being easily inferred, thereby improving security. For example, when three single layers 49 are formed in one gear portion 40, the one dial 49 rotates the dial portion 30 while pulling the latch portion 20 upward. It can be predicted as the position of the clasp groove 47 in a total of four positions including the clasp groove 47, 4x4x4x4 = 256 for the total number of four dials 30, security This is to be improved.

FIG. 5 illustrates a detailed view of a dial insertion hop and a dial support formed in a main body in a dial lock according to an embodiment of the present disclosure.

In the dial lock 1 according to an embodiment of the present disclosure, the first projection engaging groove 17a and the second projection locking groove 17b are formed inside the dial support 17. When the dial unit 30 is rotated, the gear unit 40 is rotated along the inner circumference of the dial support 17, and the latch protrusion 47 and the latch protrusion 21 are arranged on the same line. In the position where the groove is present on the dial support 17 and the long projection 41 formed outside the position corresponding to the latch projection 47 is located in the groove on the dial support 17 I could sense the senses and infer the password. Therefore, in order not to easily detect and infer this, the password is not easily inferred by forming the first projection groove 17a and the second projection groove 17b which play the same role as the groove in the dial support 17. It is not allowed. Accordingly, as shown in FIG. 3, while the length of the stepping protrusion 43 formed on the outer side of the gear part 40 is the same as the length of the long protrusion 41, the security is improved and the groove is provided. Since the first projection groove 17a and the second projection groove 17b having the same role as are formed, the security can be improved by greatly increasing the number of cases for the password.
