Description

Technical Field

[0001] The present invention relates to the technical field of password locks, and particularly relates to a mechanical digital password lock. Background Art

[0002] Early various mechanical locking devices were created based on various mechanical principles. The function of the key is to cause corresponding changes in the locking mechanism inside the lock. During the unlocking (decoding) process, only when the key code and the lock code are verified and matched consistently by the mechanism inside, can the lock bolt and lock tongue be actuated through the transmission mechanism, the lock catch be released, and the decoding be successful.

[0003] The safety performance of mechanical locks depends on two mechanical principles. One is to rely on fixed obstacles inside the lock to prevent false keys from entering and rotating. The second is to use one or more movable limiters installed inside the lock, which are determined by the key whether they are in the previously predetermined opening positions. The more of them there are, the more complex the code is, and the corresponding safety performance is improved. These principles in mechanical locks have been around for thousands of years and are still being continuously improved. The development of the key mechanical structure code still accompanies our lives today. Although more and more electronic components are used in new locks, the design of mechanical door locks will definitely continue. Although the cost of electronic devices has been greatly reduced today, with the development of material technology, it will still take a long time for electronic locks to completely replace mechanical locks.

[0004] According to the relevant regulations of "Mechanical Anti-theft Locks" in China, the main technical indicators of mechanical anti-theft lock cores. So far, the national standards for lock cores in China are limited to two types, namely Class A and Class B. Super Class B and Class C are enterprise standards proposed by lock manufacturers themselves. First, the single-row pin tumbler lock, commonly known as the Class A lock, whose anti-technical opening time standard is within 1 minute; second, the double-row pin tumbler lock, commonly known as the Class B lock, whose anti-technical opening time is within 5 minutes; third, the double-row pin tumbler lock + leaf, commonly known as the super Class B lock, whose anti-technical opening time exceeds 5 minutes; fourth, the full-leaf lock, commonly known as the Class C lock, whose anti-technical opening time far exceeds 5 minutes.

[0005] In summary, locks with lock cores of any level have the problem of being opened technically. The technical cracking and opening mainly occur in two key places: the joint surface of the lock core mechanism and the key is exposed outside. Whether it is the uneven round pits or teeth on the key corresponding to the pin tumbler lock, or the snake-shaped leaf slots of the leaf lock. It is possible to detect and open the lock using a password keyhole through auxiliary tools (such as tin foil unlocking tools, etc.). Ordinary keys are easily replicated. The password combinations are limited, and the password can be detected by the exhaustion method. Summary of the Invention

[0035] In the description of the present invention, unless otherwise clearly defined, words such as set, installed, connected, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0036] The actual production and implementation methods of the products of the present invention can be padlocks, chain locks, or can also be in the form of embedded door locks, cabinet locks, etc.

[0037] Referring to the attached Figure 1 , a mechanical digital password lock includes: a password lock housing, a lock hook mechanism, a lock core mechanism, and a marble plate.

[0038] Referring to the attached Figure 2 and the attached Figure 3 , the password lock housing is designed in various shapes according to actual needs and the combination of the lock core mechanism, and can be an external lock or an embedded type, etc. The password lock housing includes a housing 11, a plurality of keyholes 12, and a lock hook hole 14 provided on the password lock housing. The axes of the housing 11, each keyhole 12, and the lock hook hole 14 are arranged in parallel. The housing 11 is designed in different shapes according to actual needs, such as a cylinder, a petal cylinder, a cube, etc. A starting mark 13 is provided at the top of the housing 11 of the password lock housing, and the starting mark 13 is the starting identifier of the password lock.

[0039] Referring to the attached Figure 4 , the lock hook mechanism is inserted into the lock hook hole 14. The lock hook mechanism includes a lock rod 21, a lock hook groove 22, a lock hook handle 23, and a lock hook linkage module 24. The lock hook groove 22 is arranged along the circumferential side of the lock rod 21. The lock hook handle 23 is provided at one end of the lock rod 21, and the lock hook linkage module 24 is provided at the other end of the lock rod 21.

[0040] Referring to the attached Figure 7, the lock core mechanism is outside the marble plate, and several lock core units 31 are installed around the marble plate. In principle, one marble corresponds to one lock core unit 31 to form the lock core mechanism. The lock core mechanism includes the same number of lock core units 31 as the number of keyholes 12. The lock core unit 31 includes a lock core cap 32 that can move up and down and a lock core groove 33 provided on the outside of the lock core cap 32. The password value of each lock core unit 31 is determined by the position of the lock core groove 33 provided on the lock core cap 32. Each lock core cap 32 is located in the housing 11 directly below the keyhole 12; the marble plate is provided between the lock rod 21 and the lock core mechanism. One side of the marble plate contacts the lock core cap 32 of the lock core unit 31, and the other side of the marble plate contacts the lock hook groove 22 of the lock hook mechanism. Among them, when the password lock is closed, the marble plate is embedded in the lock hook groove 22 and restricts the movement of the lock rod 21; when the lock core groove 33 of each lock core cap 32 moves downward to the position of the marble plate, the lock rod 21 pushes the marble plate in the direction of the lock core groove 33, and the lock rod 21 is pulled upward to unlock and open.

[0041] In one embodiment, the lock core unit 31 further includes a lock core seat 35 and a lock core spring 34 installed on the lock core seat 35. The lock core cap 32 is sleeved on the lock core spring 34, and the lock core cap 32 is pressed to move up and down, and the lock core groove 33 is aligned with the marble plate, so that the lock rod 21 is unlocked. During installation, the lock core spring 34 is sleeved on the lock core seat 35, and then the lock core cap 32 is sleeved on the lock core spring 34.

[0042] Refer to the appendix Figure 8 and the appendix Figure 9 , the lock core value of the lock core unit 31 is determined by the position of the lock core groove 33 provided on the lock core cap 32, and the coding is carried out from top to bottom or from bottom to top. For example Figure 9 , from the number 0 - the number 6, the distance between the lock core groove 33 and the lock core seat 35 gradually increases. As long as the lock core groove 33 of the lock core cap 32 is pushed down to be aligned with the marble plate, unlocking can be achieved. Traditional keys on the market adopt a rotary type or a button type. This structure adopts a column type, and different passwords correspond to different graduation units raised by each keyhole 12. The key and the internal mechanical function module of the password lock core are isolated, and external tools cannot contact the key structure of the lock core unit 31, greatly increasing the difficulty of the lock being opened technically.

[0043] Refer to the appendix Figure 5 and the appendix Figure 6, the marble tray includes marbles 43, a marble tray housing 45, a spring mechanism 41, and marble holes 44, which are equal in number to and correspondingly arranged with the lock cylinder units 31. The marble holes 44 penetrate through the marble tray housing 45. The marble holes 44 are slightly larger than the marbles 43. The marbles 43 are installed in the marble holes 44. The marbles 43 are spherical, and of course, they can also be designed in other shapes. On the marble tray housing 45, there are spring slots 42 for installing the spring mechanism 41. One end of the spring mechanism 41 is connected to the marble tray housing 45, and the other end is connected to the marbles 43, and it can interact with the lock hook mechanism and the lock cylinder mechanism in the marble holes 44. Further, the spring mechanism 41 is a spring sheet or a torsion spring or a zigzag spring.

[0044] It can be understood that in this embodiment, the marble tray housing 45 is in the shape of a circular tube. On the marble tray housing 45, there are spherical marble holes 44 corresponding to the marbles 43 and penetrating through the tube wall. At the upper end of the marble holes 44, there are spring slots 42 for installing the spring mechanism 41, and grooves for fixing the spring mechanism 41 are provided on the tube wall. Of course, the marble tray housing 45 can also be designed in other shapes.

[0045] Refer to the appendix Figure 12 , in this embodiment, the marble tray includes marbles 43, a marble tray housing 45, a spring mechanism 41, and marble holes 4, which are equal in number to and correspondingly arranged with the lock cylinder units 31. Among them, the marbles 43 are special-shaped marbles.

[0046] Specifically, in some embodiments, the contact surface between the lock cylinder cap 32 of the lock cylinder unit 31 and the marbles 43 or the marble tray housing 45 is set to be in full contact or full suspension. A plastic layer is provided on the contact surface between the lock cylinder cap 32 of the lock cylinder unit 31 and the marbles 43 or the marble tray housing 45.

[0047] Refer to the appendix Figure 10 and the appendix Figure 11 , the appendix Figure 10 is a cross-sectional view of the password lock when it is opened, and the appendix Figure 11 is a cross-sectional view of the password lock when it is closed. As Figure 10 , when the password lock is opened, the lock cylinder groove 33 of the lock cylinder mechanism is aligned with the corresponding marbles 43. The marbles 43 have room for movement. The lock rod 21 can move and push the marbles 43 to move, so that the lock rod can be withdrawn from the lock hook hole 14. As Figure 11 , when the password lock is closed, the lock hook groove 22 of the lock rod 21 is aligned with the marbles 43. The marbles 43 have no room for movement and are in a state of mutual contact and locking with the lock rod 21.

[0048] Refer to the appendix Figure 13, the reference mechanical digital password lock further includes a key. The key part can be designed separately or integrated with the password lock. According to the actual design and production, the key mainly consists of a combination of rods with several digit lengths corresponding to the keyhole 12, and the shape is designed according to actual needs. The key includes a key disk 51 and several key rods 52. Among them, the main function of the key disk 51 is to fix the key rods 52. The length of the key rod 52 pulled out is the password value of the corresponding password unit 31 multiplied by the unit scale. Pushing the key rod 52 by the length of the key rod 52 corresponding to the lock core unit 31 can make the lock core groove 33 of the lock core unit 31 align with the marbles 43 of the marble disk corresponding to the lock core unit 31. When all the lock core grooves 33 are aligned with all the marbles 43 of the corresponding marble disk, the lock rod 21 can be pulled out or rotated.

[0049] This key is a variable password key. One password key can be set with different passwords to open different locks. Moreover, the keys of existing locks are easily replicated, while the key of this password lock is a password key and cannot be replicated if the password is not remembered.

[0050] Among them, the encapsulation part of the password lock can be designed into two types: internal encapsulation and external encapsulation. Internal encapsulation is suitable for chain locks and padlocks, and external encapsulation is suitable for door locks and cabinet locks.

[0051] This mechanical digital password lock disassembles functional modules such as the lock core mechanism and key mechanism of the original lock, combines the concept of a password lock, and re-invents a brand-new password lock. The lock core mechanism is designed as a password lock core and encapsulated inside. According to the different positions of the lock core grooves 33 of the lock core unit 31, they represent different password values. According to actual needs and the number of lock core units 31 set, a lock core mechanism is combined. The number of lock core units 31 is determined according to actual needs. The insertion scale units of the keyholes 12 of each password lock are different, corresponding to different passwords, and the password combination can be very large. For example, the combination of 10 scales and 10 groups of lock core units 31 can reach nearly 10 billion combinations. This password lock isolates the key and the internal mechanical functional module of the lock core unit 31, and external tools cannot unlock the key structure of the lock core unit 31, greatly increasing the difficulty of the lock being technically opened. The unique structure of the lock core unit 31 of this password lock and the combined processing of the lock core unit 31 can effectively prevent theft opening, and the embedded encapsulation design is adopted to improve the security of the lock and facilitate maintenance.

[0052] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
