Abstract

An anti-theft lock, comprising a password-type mechanical anti-theft lock (100), a lock control mechanism (300) and a biological recognition apparatus (200), wherein the biological recognition apparatus (200) controls, by means of controlling the lock control mechanism (300), whether the password-type mechanical anti-theft lock (100) can be unlocked by means of a correct password. During use of the anti-theft lock, after verification of a biological key is passed, the lock control mechanism (300) releases the control over an unlocking hook (110) of the password-type mechanical anti-theft lock (100) within a preset time, such that the password-type mechanical anti-theft lock (100) can be unlocked by means of a correct password; and when biological recognition verification is not passed, the lock control mechanism (300) makes the unlocking hook (110) of the password-type mechanical anti-theft lock (100) be out of contact with a driving wheel (180), such that the password-type mechanical anti-theft lock (100) is in a failed state in which the code-type mechanical anti-theft lock (100) cannot be unlocked by means of transcoding.

Description

An anti-theft lock Technical Field

[0001] The present invention relates to the technical field of anti-theft locks, and in particular to an anti-theft lock. Background Art

[0002] For a long time, password-based mechanical anti-theft locks have been widely used in high-security access control areas such as bank vaults, firearms depots, and safes. Because they are purely mechanical and require manual unlocking, they are relatively reliable and secure. However, they lack the ability to recognize the person using the code. If the password is leaked, anyone can open the lock. Furthermore, given sufficient time, thieves can still decipher the password through trial and error or by detecting the clicking sound produced when the hook of the unlocking hook passes over the contact points at the two ends of the drive wheel notch.

[0003] In recent years, biometric locks that use biometric features such as fingerprints, palm prints, and faces as keys have been widely used. Such locks consist of biometric devices and electric locks. Their advantage is accurate recognition of people, but there is a problem that biometric locks can be opened by copying keys, such as using silicone fingerprints to decipher optical fingerprint sensors and using 3D printed face models to decipher facial recognition.

[0004] In order to improve security, the existing technology adopts a solution of jointly controlling the warehouse door with a password-type mechanical anti-theft lock and a biometric lock. Although a dual authentication method of both code and person recognition is formed, and security is improved, this is just a simple superposition of the two locks and does not achieve the effect of one plus one being greater than two. There is still the problem that the password-type mechanical anti-theft lock and the biometric lock can be unlocked by technology separately.

[0005] Summary of the Invention

[0006] (1) Technical issues to be resolved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an anti-theft lock, which solves the problem that the password-type mechanical anti-theft lock and the biometric lock in the prior art can be opened by technology, and also solves the problem that the password-type mechanical anti-theft lock and the biometric lock can be opened separately by technology even after they are combined.

[0008] (2) Technical solution

[0009] In order to achieve the above object, the main technical solutions adopted by the present invention are:

[0010] An embodiment of the present invention provides an anti-theft lock, comprising:

[0011] A password-type mechanical anti-theft lock includes: an unlocking hook, a locking plate, and a driving wheel, wherein the unlocking hook is provided with a blocking rod, the locking plate is provided with a positioning slot, and there are multiple locking plates, and the multiple locking plates and the driving wheel are coaxially arranged;

[0012] When the unlocking hook is in an effective state, the unlocking hook contacts the driving wheel;

[0013] A locking control mechanism connected to an unlocking hook;

[0014] A biometric identification device for identifying biological information; the biometric identification device controls the unlocking hook to switch between a valid state and a disabled state through a lock control mechanism;

[0015] When the biometric information identified by the biometric identification device is verified, the lock control mechanism releases the control of the unlocking hook. Within the preset time, if the password-type mechanical anti-theft lock is not opened, the lock control mechanism resumes the control of the unlocking hook to be in an invalid state.

[0016] Optionally, when the biometric information identified by the biometric identification device is verified, the number of times the verification is passed is counted. If the password-type mechanical anti-theft lock is not opened and a preset number of times is reached, the recognition function of the biometric identification device is invalid within a preset period of time;

[0017] If the password-type mechanical anti-theft lock is opened, the count is reset.

[0018] Optionally, the password-type mechanical anti-theft lock includes:

[0019] A password dial is coaxially arranged with the driving wheel;

[0020] The lock tongue has one end of an unlocking hook connected to the blocking rod and the other end connected to the lock tongue;

[0021] When the lock control mechanism releases the control of the unlocking hook, the password dial drives the driving wheel to rotate, and the driving wheel drives the unlocking hook to pull the lock tongue, and the password type mechanical anti-theft lock changes from a locked state to an unlocked state.

[0022] Optionally, the password-type mechanical anti-theft lock includes:

[0023] Electromagnet, the electromagnet is attracted to the unlocking hook.

[0024] Optionally, the password-type mechanical anti-theft lock further includes:

[0025] The spring is connected to the unlocking hook and is used to pull the blocking rod closer to the locking plate when the lock control mechanism releases the control of the unlocking hook.

[0026] Optionally, the biometric identification device includes any one or more identification methods of fingerprint recognition, vein recognition, iris recognition, retina recognition, facial recognition and DNA recognition.

[0027] Optionally, the password-type mechanical anti-theft lock further includes:

[0028] A housing, wherein the unlocking hook and the locking piece are arranged in the housing;

[0029] The code disc is fixedly connected to the outer surface of the shell, and the password dial rotates relative to the code disc. (3) Beneficial effects

[0030] 1. The present invention relates to an anti-theft lock comprising a password-protected mechanical anti-theft lock, a lock control mechanism, and a biometric identification device. The biometric identification device controls the lock control mechanism to determine whether the password-protected mechanical anti-theft lock can be unlocked. This advantageously allows the lock to be unlocked only after dual authentication, including a biometric key and a mechanical password, has been successfully completed. This solves the problem of password-protected mechanical anti-theft locks recognizing passwords but not individuals. Even if the password is leaked and the biometric key fails to verify, the lock cannot be unlocked by others. Furthermore, it solves the problem of biometric locks being opened by technical means through key duplication. Without the mechanical password, even if the biometric key is copied, the lock cannot be unlocked by others.

[0031] 2. The technical solution of the present invention is that when the unlocking hook of the password-type mechanical anti-theft lock fails, the unlocking hook is disengaged from the driving wheel. Even if all the passwords of the password-type mechanical anti-theft lock are correctly aligned, the driving wheel recess cannot engage with the hook head of the unlocking hook. When someone tries to decipher the password by continuous trial and error, it is impossible to verify whether the password is correct each time. This solves the problem that the password-type mechanical anti-theft lock is technically unlocked by deciphering the password through continuous trial and error. At the same time, since the unlocking hook is disengaged from the driving wheel, there is no contact sound between the rotation of the driving wheel and the unlocking hook, which solves the problem of deciphering the password by technically unlocking by making a ticking sound when the hook head of the unlocking hook passes through the contact points at both ends of the driving wheel recess.

[0032] 3. In the technical solution of the present invention, if the biometric key verification is passed, the lock control mechanism releases the control of the unlocking hook to make it valid. If the password-type mechanical anti-theft lock is not opened within the preset time, the lock control mechanism resumes control of the unlocking hook to restore it to the invalid state. The anti-theft lock mentioned in the present invention infinitely increases the anti-technical opening time, which is a significant improvement compared to the requirement of 5.3.2.2 of "GB37481-2019 General Technical Requirements for Vault Doors" that "the anti-technical opening time of password-type mechanical anti-theft locks should be greater than or equal to 20 hours."

[0033] 4. The present invention's technical solution counts the number of successful biometric key authentication attempts, and if the password-protected mechanical anti-theft lock is unlocked, the count is reset to zero. If the password-protected mechanical anti-theft lock remains unlocked, the unlock hook remains inactive for a preset period of time after reaching a preset number of attempts. This mutual authentication between the biometric key and the mechanical password creates a one-plus-one greater-than-two effect, resolving the issue of separate technical decipherability of the mechanical password and biometric key when both a password-protected mechanical anti-theft lock and a biometric lock are installed on the same door.

[0034] 5. The unlocking hook of the password-type mechanical anti-theft lock controlled by the lock control mechanism in the technical solution of the present invention, compared with controlling other unlocking components such as dials, axial threaded rods, drive wheels, and rotating wheel groups, does not involve physical confrontation with moving parts, so that the transcoding operator cannot distinguish whether the unlocking is caused by a coding error or the hook being controlled. This not only improves the ability to prevent technical opening, but also avoids component damage or violent unlocking caused by physical confrontation caused by brute force rotation.

[0035] 6. The integrated fusion of the biometric device and the password-type mechanical anti-theft lock in the technical solution of the present invention has the following advantages compared with the solution of using a password-type mechanical anti-theft lock and a biometric lock to jointly control the warehouse or cabinet door: First, it reduces the volume of the product in the door cavity, and has a wider range of applications. It can be used not only in large warehouse doors such as bank vaults, but also in small space usage scenarios such as various safes; second, it reduces product costs, which not only reduces the cost of a lock controlled by a biometric device, but also reduces the installation workload and implementation costs; third, it can be connected to the Internet or local area network to achieve remote management, control and supervision.

[0046] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0047] 1 and 2 , the password-type mechanical anti-theft lock 100 includes: an unlocking hook 110, a locking plate 120, and a driving wheel 180. The unlocking hook 110 is provided with a blocking rod 111 and a hook head 112. The locking plate 120 is provided with a positioning groove 121. There are multiple locking plates 120, and the multiple locking plates 120 and the driving wheel 180 are coaxially arranged. The driving wheel 180 is provided with a notch 181. The blocking rod 111 of the unlocking hook 110 can enter the positioning groove 121 of the locking plate 120, and the hook head 112 of the unlocking hook 110 can engage with the notch 181 of the driving wheel 180.

[0048] When all the passwords of the password-type mechanical anti-theft lock 100 are entered correctly, the positioning grooves 121 of all the locking plates 120 are aligned in the same straight line, forming a gap. The blocking rod 111 enters the gap under the action of its own gravity or elastic force, rotates the driving wheel 180, and the hook head 112 of the unlocking hook 110 engages with the notch 181 of the driving wheel 180. Then, the driving wheel 180 drives the unlocking hook 110 to pull the lock tongue 160 back, thereby unlocking. When all the passwords of the password-type mechanical anti-theft lock 100 are entered incorrectly, the positioning grooves 121 of the locking plates 120 of the password-type mechanical anti-theft lock 100 are arranged in a staggered manner, and all the positioning grooves 121 cannot be located in the same straight line. The blocking rod 111 cannot enter the positioning grooves 121, causing the hook head 112 of the unlocking hook 110 to not engage with the notch 181 of the driving wheel 180, and the password-type mechanical anti-theft lock 100 cannot be opened.

[0049] The anti-theft lock of the present invention is additionally provided with a biometric identification device 200 and a lock control mechanism 300. If the biometric identification fails, the lock control mechanism 300 pulls up the unlocking hook 110, causing the hook head 112 of the unlocking hook 110 to disengage from the driving wheel 180 and unable to engage with the notch 181, thereby rendering the unlocking hook 110 in an invalid state.

[0050] After the biometric key verification is passed, the lock control mechanism 300 releases control of the unlock hook 110, and the hook head 112 of the unlock hook 110 contacts the drive wheel 180. Within a preset time, the lock can be unlocked with the correct password. If the password-type mechanical anti-theft lock 100 is not unlocked by transcoding, the lock control mechanism 300 resumes control of the unlock hook 110, causing the unlock hook 110 to return to an inactive state. In this technical solution, for example, the time to release control of the unlock hook 110 after the biometric key verification is passed is preset to 3 seconds. Because it generally takes 15 to 20 seconds to open a password-type mechanical anti-theft lock 100, the actual unlocking operation must be performed before the biometric verification. In this way, when the unlock hook 110 is in the valid state for 3 seconds, there is not enough time for trial and error, which prevents the unlock hook 110 from being unlocked by technical means while in the valid state.

[0051] The unlocking principle of the anti-theft lock of the present invention is as follows: First, the operator rotates the combination dial 130 of the password-type mechanical anti-theft lock 100, enters the full combination, and then performs biometric key verification. If verification is successful, the lock control mechanism 300 releases control over the unlock hook 110, and the unlock hook 110 is in an active state. If the operator's previously entered combination is completely correct, the blocking rod 111 will enter all the positioning slots 121, and the notch 181 of the drive wheel 180 will engage with the hook 112 of the unlock hook 110. Rotating the combination dial 130 then drives the drive wheel 180, which in turn drives the unlock hook 110, retracting the lock bolt 160, thereby unlocking the lock. If the password previously rotated by the operator is not completely correct, the blocking rod 111 cannot enter all the positioning grooves 121, causing the notch 181 of the driving wheel 180 to be unable to engage with the hook head 112 of the unlocking hook 110. Continuing to rotate the password dial 130 cannot open the password-type mechanical anti-theft lock 100. After 3 seconds of biometric key verification, the lock control mechanism 300 resumes control of the unlocking hook 110, making the unlocking hook 110 return to an invalid state.

[0052] This application differs from conventional double-locking technologies that combine a combination of a password-based mechanical anti-theft lock 100 and a biometric lock. By providing a biometric identification device 200, the unlocker's biometric key can be verified. Whether the recognized biometric key passes verification determines whether the lock control mechanism 300 releases control of the unlock hook 110, switching the unlock hook 110 between an active and inactive state. When a thief attempts to crack a conventional password-based mechanical anti-theft lock 100, they can decipher the code by trial and error or by listening for the clicking sound produced when the hook 112 of the unlock hook 110 passes the contact points on both ends of the notch 181 of the drive wheel 180. The anti-theft lock of the present application pulls up the unlocking hook 110, causing the hook head 112 of the unlocking hook 110 to disengage from the drive wheel 180. When someone attempts to decipher the password using a trial-and-error method, the correctness of each attempted password cannot be verified, making it difficult to decipher the password through trial-and-error. Furthermore, since the unlocking hook 110 is disengaged from the drive wheel 180, there is no contact sound between the rotation of the drive wheel 180 and the unlocking hook 110. This prevents thieves from deciphering the password by making the click sound produced when the hook head 112 of the unlocking hook 110 passes the contact points at both ends of the notch 181 of the drive wheel 180. Furthermore, even if a thief obtains the password of the password-protected mechanical anti-theft lock 100 through improper means, if they fail biometric verification, the unlocking hook 110 will be inoperative and the lock will be unavailable.

[0053] In the present technical solution, when the biometric key identified by the biometric identification device 200 is verified, the number of times the verification is passed is counted, and if the password-type mechanical anti-theft lock 100 is opened, the count is reset to zero; if the password-type mechanical anti-theft lock 100 is not opened, when the preset number of times is reached, the unlocking hook 110 remains in an invalid state within a preset period of time.

[0054] Referring to FIG. 8, in FIG. 8, n represents the number of successful biometric verifications, x represents the defined number of successful biometric verifications, and y represents the failure time of the unlocking hook 110. When the password-based mechanical anti-theft lock 100 is opened, the count is cleared and n = 0. Each time the biometric key verification is successful, the count is incremented by 1, i.e., n = n + 1. When n < x, that is, less than the defined number of successful biometric verifications, the unlocking hook 110 is released and the unlocking count is cleared; when n = x, that is, when the defined number of successful biometric verifications is reached, the unlocking hook 110 fails within the time y. Exemplarily, the biometric recognition device 200 is used to control the unlocking hook 110 such that the hook head 112 of the unlocking hook 110 cannot engage with the notch 181 of the driving wheel 180. Only when the biometric recognition device 200 passes the verification can the control of the unlocking hook 110 be released, so that the lock can be opened with the correct password, thereby achieving the effect of controlling the password-based mechanical anti-theft lock 100 through the biometric recognition device 200. When the biometric key verification recognized by the biometric recognition device 200 is successful, the number of successful verifications is counted. If the password-based mechanical anti-theft lock 100 is opened, the count is cleared; if the password-based mechanical anti-theft lock 100 is not opened, when the preset number of times is reached, the unlocking hook 110 remains in the failure state within the preset period.

[0055] It should be noted that the above preset time, preset number of times, and preset period need to be set in advance and are fixed and unchanged during the unlocking process. It can be understood that the present application does not limit the magnitudes of the above preset time, preset number of times, and preset period, and any magnitudes considered appropriate by the user can be set.

[0056] Referring to FIG. 7, FIG. 7 shows the electronic circuit diagram of an embodiment of the biometric recognition device 200 proposed in the present application. Exemplarily, the biometric recognition device 200 may include a biometric recognition module, an unlocking control unit, a power management unit, an RTC clock unit, an input display unit, a wired ETH unit, a wireless WIFI unit, a buzzer alarm unit, etc. The biometric recognition device 200 is integrated with the password-based mechanical anti-theft lock 100 and can access the Internet or a local area network to achieve remote management, control, and supervision.

[0057] Reference Figure 3 is a schematic structural diagram of an embodiment of the first locking control mechanism 300 of the anti-theft lock of the present invention. In this technical solution, the elastic force of the spring 170 is in the same direction as the hook head 112. The locking control mechanism 300 includes an electrified suction cup electromagnet 311 and an electrified armature 312. The electrified armature 312 is installed on the unlocking hook 110. The electrified armature 312 is installed at a position corresponding to the electrified armature 312. When the electrified suction cup electromagnet 311 is powered off, it loses its magnetic force, and the electrified armature 312 is released. Under the action of the elastic force of the spring 170, the unlocking hook 110 is in an effective state; when the electrified suction cup electromagnet 311 is powered on, it generates magnetic force, overcomes the elastic force of the spring 170, and the electrified armature 312 is sucked up by the magnetic force, thereby putting the unlocking hook 110 in an invalid state.

[0058] Reference Figure 4 is a schematic structural diagram of an embodiment of a second lock control mechanism 300 of an anti-theft lock of the present invention. In this technical solution, the elastic force of the spring 170 is in the same direction as the hook head 112. The lock control mechanism 300 includes a de-energized suction cup electromagnet 321 and a de-energized armature 322. The de-energized armature 322 is installed on the unlocking hook 110. The de-energized armature 322 is installed at a position corresponding to the de-energized armature 322. When the de-energized suction cup electromagnet 321 is energized, the magnetic force is lost, and the de-energized armature 322 is released. Under the action of the elastic force of the spring 170, the unlocking hook 110 is in an effective state; when the de-energized suction cup electromagnet 321 is de-energized, a magnetic force is generated, which overcomes the elastic force of the spring 170 and the de-energized armature 322 is sucked up by the magnetic force, thereby making the unlocking hook 110 in an invalid state.

[0059] Reference Figure 5 is a schematic structural diagram of an embodiment of the third locking control mechanism 300 of the anti-theft lock of the present invention. In this technical solution, the elastic force of the spring 170 is opposite to the hook head 112, and the locking control mechanism 300 includes a first push-pull electromagnet 331 and a first movable armature 332. When the first push-pull electromagnet 331 is energized, one end of the first movable armature 332 touches the unlocking hook 110 to overcome the elastic force of the spring 170, so that the unlocking hook 110 is in an effective state; when the first push-pull electromagnet 331 is de-energized, the first movable armature 332 loses its magnetic force, and the unlocking hook 110 is in an invalid state under the action of the elastic force of the spring 170.

[0060] Reference Figure 6 is a schematic structural diagram of an embodiment of the fourth locking control mechanism 300 of the anti-theft lock of the present invention. In this technical solution, the elastic force of the spring 170 is opposite to the hook head 112, and the locking control mechanism 300 includes a second push-pull electromagnet 341, a second movable armature 342, and an armature spring 343. When the second push-pull electromagnet 341 is powered off, the second movable armature 342 overcomes the elastic force of the spring 170 under the action of the elastic force of the armature spring 343, so that the unlocking hook 110 is in an effective state; when the second push-pull electromagnet 341 is powered on, the magnetic force of the second movable armature 342 overcomes the elastic force of the armature spring 343, so that the unlocking hook 110 is in an invalid state.

[0061] The following describes the trial and error process of a thief by way of example, so as to fully illustrate the security of the anti-theft lock of the present invention.

[0062] The thief first turns the password-type mechanical anti-theft lock 100 to match a set of passwords, and then performs biometric verification. Even if the biometric recognition is successful, if the mechanical password is incorrect, the lock cannot be opened. Of course, if the biometric recognition is unsuccessful, the lock cannot be opened, and the thief does not know whether the mechanical password is correct at this time, so the password cannot be deciphered by trial and error. In addition, the lock cannot be unlocked after multiple biometric verifications are passed, and the unlocking function is prohibited for a period of time. In this way, the anti-theft lock of the present invention infinitely increases the anti-technical opening time, which is greatly improved compared to the requirements of 5.3.2.2 of "GB37481-2019 General Technical Requirements for Vault Doors" "The anti-technical opening time of the password-type mechanical anti-theft lock 100 should be greater than or equal to 20h".

[0063] In this technical solution, the biometric identification device 200 includes any one or more identification methods of fingerprint recognition, vein recognition, iris recognition, retinal recognition, facial recognition and DNA recognition. At least one of the multiple biometric identifications can be selected so that they can be combined with each other, thereby further improving the security of the password-type mechanical anti-theft lock 100.

[0064] In this technical solution, the password-type mechanical anti-theft lock 100 further includes:

[0065] The housing 140 , the unlocking hook 110 and the locking piece 120 are disposed in the housing 140 ;

[0066] The code disc 150 is fixedly connected to the outer surface of the housing 140 , and the password dial 130 rotates relative to the code disc 150 .

[0067] It should be noted that a shell 140 is provided, wherein the unlocking hook 110 and the lock plate 120 are provided inside the shell 140, which shields the internal structure of the password-type mechanical anti-theft lock 100, that is, the connection relationship between the lock plate 120 and the unlocking hook 110, the transmission relationship between the multiple lock plates 120, the positional relationship of the positioning grooves 121 on the multiple lock plates 120, etc., so that the operator cannot know the transmission relationship of the password-type mechanical anti-theft lock 100, thereby improving the security of the password-type mechanical anti-theft lock 100.

[0068] It should be noted that a coding disc 150 is provided, wherein the coding disc 150 is fixedly connected to the outer surface of the shell 140, and the password dial 130 rotates relative to the coding disc 150. For example, the coding disc 150 is marked with standard scale lines corresponding to the locking plate 120. The rotation of the above-mentioned password dial 130 relative to the scale lines of the coding disc 150 can effectively realize the control of the locking plate 120, thereby improving the convenience of operation.
