Description

Technical Field

[0001] The utility model relates to the technical field of password locks, in particular to a garbled code structure of a password lock. Background Art

[0002] A combination lock is a type of lock that uses a series of numbers or symbols to open. Combination locks can be categorized as mechanical or digital. The combination is usually a permutation, not a true combination. Some combination locks use a single dial that rotates several discs or cams inside the lock, while others use a numbered dial ring to directly activate the lock's internal mechanism.

[0003] According to an automatic scrambler for a password lock disclosed in Chinese patent publication No. CN219034352U, it includes a door panel, a knob rotatably connected to the surface of the door panel, an adjustment device provided in the inner cavity of the door panel, a plurality of first sliding grooves provided on the side of the conical slider of the adjustment device, a sliding rod slidably connected in each first sliding groove, and the meshing teeth at one end of the sliding rod are connected to the scrambler structure through a chain; the chain is connected to the transmission gear of the scrambler structure, and the scrambler structure drives the driving gear and the driven gear to engage through the electromagnet to attract the iron block, so that after the staff closes the door panel, the servo motor can drive the knob to rotate through the transmission mechanism, thereby achieving the scrambling effect; by pressing the knob, the movement of the slider of the adjustment device can be controlled, thereby changing the transmission ratio between the slider and the scrambler structure, making the scrambler more random and further improving the safety performance.

[0004] However, this patent still has certain shortcomings in actual use. First, when a garbled operation is required, the driving gear and the driven gear need to be engaged from a separated state. It is very difficult to ensure that the two gears do not rotate naturally during the movement, and the processing requirements and precision are high. At the same time, by changing the transmission ratio to make the rotation rate of the garbled operation different, its core is still just to change the actual angle and position of the rotation. The corresponding effect can also be achieved by controlling the rotation time through the servo motor. The method is relatively useless. In this regard, the present application provides a garbled structure of a password lock by simplifying the structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4The utility model provides a technical solution: a code-binding structure of a password lock, comprising a password cabinet 1, a cabinet door 2 hingedly connected to the front of the cabinet door 2 by a hinge, a password lock body 3 fixedly installed on the front of the cabinet door 2, a lock core rotating shaft 4 fixedly installed on the input end of the password lock body 3, an installation cavity is opened inside the cabinet door 2, and a code-binding component is installed inside the installation cavity; through the coordination between the cabinet door 2 on the front of the password cabinet 1, the password lock body 3, the lock core rotating shaft 4 and the code-binding component, the code-binding operation of the password lock can be realized through a simple structure, so that it can be used conveniently, and a certain error can be allowed during use, thereby reducing the processing requirements and precision, making it easier to put into use, so that it can meet the code-binding requirements of the password lock, and improving the security and practicality of the password lock.

[0027] In this embodiment, the garbled code component is a structure for performing garbled code control on the lock core.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the garbled code component includes an installation box 501 fixed on the inner side of the installation cavity, a driving mechanism 502 fixedly installed on the back side of the installation box 501, a driving shaft 503 rotatably connected to the inner side of the installation box 501 through a bearing, a driving wheel 504 fixedly installed on the outside of the driving shaft 503, a driven cylinder 505 rotatably connected to the inner rear side wall of the installation box 501 through a bearing, a driven wheel 506 fixed on the outside of the driven cylinder 505, an electric push rod 507 fixed on the back side of the driven cylinder 505, a limit block 508 fixed on the output shaft of the electric push rod 507, four laser receiving plates 509 fixedly installed on one end of the back side of the lock core shaft 4, four laser sensors 510 fixedly installed on the inner rear side wall of the driven cylinder 505, and a limit slot 511 opened at one end of the back side of the lock core shaft 4.

[0029] It should be noted that the output shaft of the driving mechanism 502 passes through the back of the installation box 501 and is fixedly connected to the back end of the active shaft 503, so that the driving mechanism 502 can drive the active shaft 503 to rotate. The driving mechanism 502 can be a servo motor, and the back side of the driven cylinder 505 passes through the back of the installation box 501. The front side of the driven cylinder 505 is open, and the back end of the lock core shaft 4 extends to the interior of the driven cylinder 505, so that the lock core shaft 4 can rotate normally inside the driven cylinder 505, and the outer side of the lock core shaft 4 does not fit into the inner side of the driven cylinder 505, so that the lock core shaft 4 can be driven to rotate normally by the combination lock body 3 without being restricted.

[0030] In addition, the outer side of the driven wheel 506 is meshed with the outer side of the driving wheel 504, so that the driving wheel 504 can drive the driven wheel 506 to rotate, and the output shaft of the electric push rod 507 passes through the back side of the driven cylinder 505 and extends to its interior. The limit block 508 and the limit groove 511 are both square, and the limit block 508 can be inserted into the inner side of the limit groove 511, so that the limit block 508 can be driven by the electric push rod 507 to be inserted into the inner side of the limit groove 511, wherein the limit groove 511 is slightly larger than the limit block 508, so that there is a certain surplus between the limit block 508 and the limit groove 511, which reduces the processing difficulty and can allow a certain error between the laser sensor 510 and the laser receiving board 509.

[0031] At the same time, if Figure 4 As shown, the four laser receiving plates 509 are respectively located on the four sides of the limiting groove 511, and the four laser receiving plates 509 respectively correspond to the positions of the four laser sensors 510, so that the laser receiving plates 509 can receive and reflect the laser emitted by the laser sensor 510, and then the position can be judged and located through the four laser sensors 510.

[0032] It should also be noted that the combination lock body 3 has multiple lock core shafts 4, which are used to control the rotation of different combination wheels. The position distribution of these shafts and gears is different. Specifically, the rotation of different combination wheels can be controlled by shafts of different lengths and sizes, and each lock core is provided with a garbled code component on the outside. The layout of the garbled code component needs to be separated from other lock core shafts 4 so that it can control and manipulate the corresponding lock core shaft 4.

[0033] The working principle of the above embodiment is:

[0034] When it is necessary to perform a garbled operation on the lock core shaft 4, the driving mechanism 502 is started through the cooperation between the laser sensor 510 and the laser receiving plate 509, driving the active shaft 503 to rotate, so that the active wheel 504 rotates and drives the driven wheel 506 to rotate, and then the driven cylinder 505 rotates, so that the four laser sensors 510 can match the four laser receiving plates 509 respectively. At this time, the position between the limit block 508 and the limit groove 511 corresponds to each other, and the electric push rod 507 is started to drive the limit block 508 to be inserted into the inner side of the limit groove 511, and the driving mechanism 502 can be started again, and the driven wheel 506 is driven to rotate through the active wheel 504, so that the driven cylinder 505 rotates, and the limit cooperation between the limit block 508 and the limit groove 511 drives the lock core shaft 4 to rotate, thereby realizing the garbled operation on the lock core shaft 4.

[0035] Compared with the existing technology, the scrambled code structure of the password lock can realize the scrambled code operation of the password lock through the coordinated use of the cabinet door 2 on the front of the password cabinet 1, the password lock body 3, the lock core shaft 4 and the scrambled code component through a simple structure, so that it can be used conveniently, and a certain error can be allowed during use, thereby reducing the processing requirements and precision, making it easier to put into use, so that it can meet the scrambled code requirements of the password lock, improving the safety and practicality of the password lock, and solving the problem that the existing automatic scrambler of the password lock is relatively complicated in the actual transmission process and requires a higher level of process.

The power supply can be an external power supply, and the main controller can be a conventional known device such as a PLC controller for control. It can be implemented through simple programming by technicians in this field, and they are all existing publicly available power connection technologies and will not be described in detail in this article.
