[0042] The present application provides a lock 100 with double locking of password and lock cylinder.

[0043] Please refer to Figure 1 The lock 100 comprises: a lock body 10; a lock hook 20 movably arranged in the lock body 10, the lock hook 20 having a locking position and an unlocking position; a lock cylinder assembly 30 comprising a lock cylinder 31 rotatably arranged in the lock body 10, the lock cylinder assembly 30 cooperating with the lock hook 20 to unlock or lock the lock hook 20, so that the lock hook 20 switches between the locking position and the unlocking position; a password assembly 40 rotatably arranged in the lock body 10, so that the password assembly 40 can lock or release the lock cylinder 31, when the password assembly 40 releases the lock cylinder 31, rotating the lock cylinder 31 to unlock the lock hook 20; when the password assembly 40 locks the lock cylinder 31, rotating the lock cylinder 31, the lock cylinder 31 is fixed, so that the lock hook 20 is in the locking position.

[0044] The technical scheme of the present application locks the lock cylinder 31 through the password assembly 40, the lock cylinder 31 can lock the lock hook 20, when unlocking is needed, the password assembly 40 needs to be unlocked to release the lock cylinder 31, then the lock hook 20 can be in the unlocked position by rotating the lock cylinder 31, the password assembly 40 and the lock cylinder assembly 30 need to be unlocked at the same time to unlock the lock 100. The scheme uses the lock cylinder 31 and the password disc 41 for double locking, which improves the security of the lock 100. Even if the corresponding mechanical key of the lock cylinder assembly 30 is lost, the lock 100 cannot be opened at will; similarly, even if the password is known, the lock 100 cannot be opened without a mechanical key.

[0045] To further illustrate the innovative requirements of the mechanical anti-misoperation lock in the power anti-misoperation system, and to solve the problem of the lock cylinder and key being of a unified specification, one mechanical key can open the lock with the corresponding lock cylinder, the following three aspects are described to illustrate the creative concept of the present application:

[0046] (1) Intelligentization (electronicization): Instead of using mechanical locks, electronic locks or smart locks (Bluetooth locks, NFC locks, fingerprint locks, etc.) are used. Electronic locks do not have mechanical lock openings and do not have traditional lock cylinder modules. Even if there is a mechanical lock opening, it cannot be opened in a non-emergency situation. In this case, the anti-misoperation locking requirement in the power anti-misoperation system requires thousands of anti-misoperation locks in a substation, and the reliability of electronic locks or smart locks is greatly tested. The effectiveness of electronic modules such as Bluetooth, fingerprint, and NFC, as well as the high cost of battery power monitoring or maintenance of locks, mechanical anti-misoperation locks have obvious technical advantages in this application scenario.

[0047] (2) Mechanical modification: Continue to use mechanical locks without changing the mechanical properties of mechanical locks. Improve the mechanical lock, such as the concept of the present application, add a mechanical password mechanism, and a corresponding locking mechanism for the limit lock cylinder. The technical advantages of traditional mechanical anti-misoperation locks are retained, and the existing technical problems are improved.

[0048] (3) Electromechanical modification: Continue to use mechanical locks and add electronic modules (Bluetooth, fingerprint recognition, face recognition, NFC, etc.). Retain the functional modules of the mechanical lock and add the functional modules of the smart lock. Although the problems of traditional mechanical anti-misoperation locks are solved, such product solutions have the highest cost, have the functions of traditional anti-misoperation locks, have the performance of smart anti-misoperation locks, and have the problems of smart lock product performance reliability in the power anti-misoperation scene (for example, high quality requirements for electronic components), and high product maintenance cost (for example, lock battery monitoring and maintenance).

[0049] The password assembly 40 can limit the rotation of the lock cylinder 31 in various ways. For example, the password assembly 40 can extend into the lock body 10 to limit the lock cylinder 31 and the lock body 10 together, so that the lock cylinder 31 cannot rotate relative to the lock body 10 when the key is rotated. In addition, a limiting component can be additionally provided on the rotation shaft of the lock cylinder 31, and the rotation of the limiting component needs to be limited to limit the rotation of the lock cylinder 31. The specific implementation modes are not listed one by one, and no specific limitation is made herein.

[0050] Specifically, the lock body 10 is provided with a cavity and a lock hole 16 communicating with the cavity, the lock cylinder assembly 30 and the password assembly 40 are arranged in the cavity, and the lock hook 20 is movably arranged in the lock hole 16. The lock hook 20 is generally in the shape of an inverted "U", and the lock hook 20 includes a long end and a short end. The long end cooperates with the lock cylinder assembly 30, and when the long end of the lock hook 20 is unlocked, the lock hook 20 is popped out of the lock body 10 as a whole, the short end of the lock hook 20 extends out of the lock body 10, and the lock hook 20 can rotate around the long end as a whole to realize the unlocking of the lock.

[0051] Please refer to Figure 1 and Figure 2 The password assembly 40 includes a password disc rotating shaft 42 and a password disc 41 sleeved on the password disc rotating shaft 42. The password disc 41 drives the password disc rotating shaft 42 to rotate to release or block the password disc rotating shaft 42, so that the lock cylinder 31 is unlocked or locked. When the password disc 41 is in the correct position, the password disc rotating shaft 42 can be moved relative to the password disc 41 to unlock the lock cylinder 31.

[0052] In this embodiment, the password assembly 40 includes the password disc rotating shaft 42 and the password disc 41. The password disc 41 is sleeved on the outer periphery of the password disc rotating shaft 42, and one end of the password disc rotating shaft 42 cooperates with the lock cylinder 31. By limiting the rotation of the password disc 41 by the password disc rotating shaft 42, the unlocking and locking of the password assembly 40 are realized.

[0053] Please refer to Figure 2 Generally, the outer circle of the password disc 41 has ten numbers from 0 to 9, indicating different password numbers. The password disc 41 is provided with a plurality of password discs to increase the difficulty of password unlocking. When all the password discs 41 are in the correct position, that is, the numbers on all the password discs 41 are correct, the password disc 41 can unlock the password disc rotating shaft 42. At this time, the password disc rotating shaft 42 moves relative to the password disc 41, thereby releasing the lock cylinder 31.

[0054] It should be noted that after the password disc rotating shaft 42 moves relative to the password disc 41, the password disc rotating shaft 42 no longer limits the password disc 41. At this time, the password disc 41 can rotate relative to the password disc rotating shaft 42, that is, the password can be changed. That is to say, when the password needs to be changed, the password assembly 40 needs to be unlocked first.

[0055] Please refer to Figure 1And Figure 6 The password assembly 40 further comprises a limiting member 44, and the password disc 41 is provided with a limiting groove 412 in the outer periphery, and the limiting member 44 is in abutment with the limiting groove 412 and the lock body 10 at both ends.

[0056] In order to prevent the password disc 41 from rotating randomly after being unlocked, the password disc 41 is provided with the limiting groove 412 in the outer periphery, and each limiting groove 412 is arranged between two adjacent numbers, when the limiting member 44 is clamped in the corresponding limiting groove 412, the password disc 41 cannot rotate randomly, and the actual password is inconsistent with the password designed by the user, so that the password assembly 40 cannot be unlocked, thereby reducing the user experience.

[0057] Specifically, the limiting member 44 is arranged in the cavity of the lock body 10, the limiting member 44 comprises a spring 441 and a steel ball 442, one side of the steel ball 442 is in elastic abutment with the spring 441, the other side of the steel ball 442 is in contact with the outer periphery of the password disc 41, the spring 441 provides power for the steel ball 442 to move to the password disc 41, when the password disc 41 needs to rotate, the steel ball 442 is pressed, thereby compressing the spring 441. When the steel ball 442 is clamped in the limiting groove 412, the password disc 41 cannot rotate randomly. In addition, in the process of rotating the password disc 41, the steel ball 442 is in contact with the concave-convex part of the outer periphery of the password disc 41, which also gives the user a certain hand feeling and prompts the user to the number of digits rotated.

[0058] Please combine Figure 2 , Figure 6 and Figure 7 The password disc shaft 42 is provided with a clamping convex 422, the password disc 41 is provided with a clamping groove 411 corresponding to the clamping convex 422, the password disc 41 drives the password disc shaft 42 to rotate through the cooperation of the clamping convex 422 and the clamping groove 411, and the lock body 10 is provided with an avoiding groove 11 corresponding to the clamping convex 422, when the password disc 41 is in the correct position, the avoiding groove 11 is aligned with the clamping convex 422, so as to release the password disc shaft 42.

[0059] In the embodiment, when the password disc 41 is in the wrong position, the clamping convex 422 of the password disc shaft 42 is misaligned with the avoiding groove 11 of the lock body 10, at this time, the password disc shaft 42 cannot move axially, and the lock cylinder 31 cannot be released, and the axial movement of the password disc shaft 42 is limited by the lock body 10. In addition, by default, the clamping convex 422 of the password disc shaft 42 is clamped with the clamping groove 411 in the password disc 41 in the circumferential direction, so as to drive the password disc shaft 42 to rotate through the password disc 41.

[0060] Generally, the password disc 41 is provided with ten numbers from 0 to 9 on the periphery, and the password disc 41 has ten corresponding card slots 411 inside, while the password disc rotating shaft 42 has a card protrusion 422, which is matched with one of the card slots 411 of the password disc 41 by default, and the password disc rotating shaft 42 can still return to one of the card slots 411 after the password.

[0061] Please refer to Figure 5 , Figure 6 and Figure 7 , the lock cylinder assembly 30 comprises a lock cylinder rotating shaft 32 drivingly connected with the lock cylinder 31, the lock cylinder rotating shaft 32 is provided with an unlocking portion 321 and a locking portion 322, when the password disc 41 is in the correct position, the lock cylinder 31 drives the lock cylinder rotating shaft 32 to rotate, and the lock cylinder rotating shaft 32 switches from abutting against the password disc rotating shaft 42 at the locking portion 322 to abutting against the password disc rotating shaft 42 at the unlocking portion 321, thereby pushing the password disc rotating shaft 42 to move, and the lock cylinder rotating shaft 32 releases the lock hook 20.

[0062] In this embodiment, when the password is correct, the lock cylinder rotating shaft 32 is no longer limited by the lock body 10, and the password disc rotating shaft 42 has a space for axial movement, at this time, the lock cylinder rotating shaft 32 can rotate, so that the key can rotate the lock cylinder 31, and the lock cylinder 31 releases the lock hook 20, thereby achieving the unlocking of the lock. At this time, when the password is in the correct position, the lock cylinder rotating shaft 32 pushes the password disc rotating shaft 42 to move during the process of rotating to the unlocking position, that is, the password disc 41 can be rotated to change the password.

[0063] Please refer to Figure 6 and Figure 8 , the password assembly 40 further comprises a transmission rod 43, the password disc rotating shaft 42 is sleeved on the transmission rod 43, the password disc 41 and the password disc rotating shaft 42 can rotate relative to the transmission rod 43, the lock cylinder rotating shaft 32 is further provided with a password changing portion 323, when the password disc 41 is in the correct position, the lock cylinder 31 rotates to drive the lock cylinder rotating shaft 32 to rotate, the lock cylinder rotating shaft 32 switches from abutting against the transmission rod 43 at the unlocking portion to abutting against the transmission rod 43 at the password changing portion 323, so as to drive the transmission rod 43 and the password disc rotating shaft 42 to move axially.

[0064] Preferably, the password assembly 40 further comprises a transmission rod 43, the password disc 41 and the code disc rotating shaft are both arranged in a ring shape, the transmission rod 43 is movably arranged through the code disc rotating shaft 42, the code disc rotating shaft 42 is sleeved with the password disc 41, one end of the transmission rod 43 is matched with the lock cylinder 31, when the password disc 41 is rotated to the correct position, the password changing portion 323 of the lock cylinder rotating shaft 32 abuts against the transmission rod 43 during the process, thereby pushing the transmission rod 43 and the password disc rotating shaft 42 to move axially, at this time, the password disc 41 can be rotated alone to change the password.

[0065] It should be noted that when the unlocking position of the lock core rotating shaft 32 is in abutment with the transmission rod 43, only the transmission rod 43 can be pushed to move axially, at this time only the unlocking function can be realized, and the password changing function cannot be realized. By such setting, different functions can be realized when different parts (the unlocking part 321, the locking part 322 and the password changing part 323) of the lock core rotating shaft 32 are in abutment with the transmission rod 43, thereby optimizing the user experience.

[0066] It can be understood that although the password changing can be realized without setting the transmission rod 43, at this time both the unlocking and the password changing can be realized. In the embodiment, the transmission rod 43 is set, when the unlocking position of the lock core rotating shaft 32 is in abutment with the transmission rod 43, only the transmission rod 43 can be pushed to move axially, the password disc rotating shaft 42 cannot be pushed to move, at this time the password disc 41 is limited by the password disc rotating shaft 42, the password disc 41 cannot rotate, only the unlocking function can be realized, and the password changing function cannot be realized; when the password changing position of the lock core rotating shaft 32 is in abutment with the transmission rod 43, the transmission rod 43 and the password disc rotating shaft 42 are simultaneously pushed to move, the password disc 41 can rotate, the password changing can be realized. Different functions can be realized when different parts (the unlocking part 321, the locking part 322 and the password changing part 323) of the lock core rotating shaft 32 are in abutment with the transmission rod 43, thereby optimizing the user experience.

[0067] Please refer to Figure 5 , the circumference of the lock core rotating shaft 32 is the password changing part 323, the circumference of the lock core rotating shaft 32 is also provided with the first groove and the second groove to form the unlocking part 321 and the locking part 322 respectively, and the depth of the first groove is less than the depth of the second groove.

[0068] In the embodiment, the position where the lock core rotating shaft 32 cooperates with the transmission rod 43 has an arc change, the circumference of the lock core rotating shaft 32, the first groove and the second groove are respectively the password changing part 323, the unlocking part 321 and the locking part 322. Different parts cooperate with the transmission rod 43, the distance of pushing the transmission rod 43 to move is different.

[0069] Specifically, when the locking part 322 (the second groove) is in abutment with the transmission rod 43, the transmission rod 43 is in the state of stretching out, that is, close to the position of the lock core 31; when the unlocking part 321 (the first groove) is in abutment with the transmission rod 43, since the depth of the first groove is less than the depth of the second groove, the unlocking rotating shaft will push the transmission rod 43 to move a first distance in the direction away from the lock core 31; during the process that the password changing part 323 (the circumference of the lock core rotating shaft 32) is in abutment with the transmission rod 43, the unlocking rotating shaft will push the transmission rod 43 and the password disc 41 to rotate to move a second distance in the direction away from the lock core 31, and the second distance is greater than the first distance. In fact, as long as the distance of moving the transmission rod 43 during the rotation of the lock core rotating shaft 32 has three, it can be realized by the three structures of the convex, the circumference and the groove, or the circumference and the two grooves can be adopted, which is not limited here.

[0070] Please refer to Figure 2 and Figure 8 The transmission rod 43 is provided with a limiting block 431, and the inner side wall of the password disc rotating shaft 42 is provided with a slot 421 corresponding to the limiting block 431. The slot 421 extends along the axial direction of the password disc rotating shaft 42. The depth of the first groove is greater than the depth of the slot 421. When the password disc 41 is in the correct position, the limiting block 431 is aligned with the slot 421. When the unlocking position is in abutment with the transmission rod 43, the lock core rotating shaft 32 pushes the transmission rod 43 to move. When the unlocking position is in abutment with the transmission rod 43, the limiting block 431 is in abutment with the slot 421, and the transmission rod 43 drives the password disc rotating shaft 42 to move synchronously.

[0071] Because the inner side wall of the password disc rotating shaft 42 is provided with the slot 421, and the depth of the first groove is greater than the depth of the slot 421, when the unlocking part 321 (the first groove) is in abutment with the transmission rod 43, the transmission rod 43 moves a distance, but the distance is not enough to overcome the depth of the slot 421, that is, at this time, the transmission rod 43 moves backward, but does not contact the password disc rotating shaft 42 in the axial direction, so it does not drive the password disc rotating shaft 42 to move. When the changing password part 323 is in abutment with the transmission rod 43 and pushes the transmission rod 43 to move, the limiting block 431 moves a distance equal to the depth of the slot 421. At this time, the transmission rod 43 is in contact with the password disc rotating shaft 42 in the axial direction, and drives the password disc rotating shaft 42 to move synchronously.

[0072] Please refer to Figure 3 The lock body 10 is provided with a mounting groove 12, and the password disc 41 is arranged in the mounting groove 12. The lock body 10 is also provided with a sliding groove 13 vertically communicating with the mounting groove 12, and the transmission rod 43 and the password disc rotating shaft 42 are movably arranged in the sliding groove 13.

[0073] Further, the lock body 10 is provided with the mounting groove 12, and the number of the mounting grooves 12 is consistent with the number of the password discs 41. Usually, the mounting grooves 12 are provided in plurality, and the plurality of mounting grooves 12 are arranged at intervals. One side of the mounting groove 12 penetrates through the lock body 10, so that a part of the outer circumferential surface of the password disc 41 is located on the surface of the lock body 10, so as to facilitate the rotation of the password disc 41.

[0074] During installation, the password disc 41 and the password disc rotating shaft 42 are matched, and then are sunk into the mounting groove 12 from the surface of the lock body 10. The side of the lock body 10 is provided with a through hole, the transmission shaft passes through the password disc rotating shaft 42 from the side of the lock body 10, and then the side plug 14 is used to plug the through hole, so as to realize the installation of the password assembly 40. In addition, the groove bottom of the mounting groove 12 penetrates through the bottom of the lock body 10, the limiting piece 44 penetrates through the bottom of the lock body 10 and is in abutment with the password rotating disc, and the lock body 10 is also provided with a bottom plug 15. The bottom plug 15 is in interference fit with the lock body 10, so as to fix the limiting piece 44 in the cavity of the lock body 10.

[0075] Please refer toFigure 1 and Figure 6 The password assembly 40 further comprises a first reset member 423 and a second reset member 432. The first reset member 423 is arranged between the password dial shaft 42 and the lock body 10, and the second reset member 432 is arranged between the transmission rod 43 and the lock body 10.

[0076] In the present embodiment, the first reset member 423 and the second reset member 432 are respectively arranged to reset the password dial shaft 42 and the transmission rod 43. When the lock cylinder shaft 32 is rotated to push the password dial shaft 42 and the transmission rod 43 back, the first reset member 423 and the second reset member 432 are respectively arranged to reset the password dial shaft 42 and the transmission rod 43 after the lock cylinder shaft 32 is rotated back.

[0077] Please refer to Figure 1 and Figure 9 The lock further comprises a locking member 50 connected with the lock cylinder 31. The locking member 50 has a first position for locking the lock hook 20 and a second position for unlocking the lock hook 20. The lock cylinder shaft 32 drives the locking member 50 to move between the first position and the second position to lock or unlock the lock hook 20. The locking member 50 is provided with a boss 51, and the lock cylinder shaft 32 is provided with a clamping table 324. When the lock hook 20 is in the locked position, the boss 51 cooperates with the clamping table 324 to limit the rotation of the lock cylinder shaft 32. When the lock hook 20 is in the unlocked position, the boss 51 is separated from the clamping table 324 to allow the lock cylinder shaft 32 to rotate.

[0078] In the present embodiment, when the lock hook 20 is in the locked position, the boss 51 of the locking member 50 cooperates with the clamping table 324 of the lock cylinder shaft 32, and the boss 51 of the locking member 50 blocks the counterclockwise rotation of the lock cylinder shaft 32. Therefore, the lock cylinder 31 cannot be rotated to change the password. At this time, the lock cylinder shaft 32 can only rotate in the other direction (unlocking direction). For details, please refer to Figure 10 When the lock is unlocked (when the lock hook 20 is extended), the locking member 50 is pushed by the lock hook 20 to move backward, and the side boss 51 of the locking member 50 is separated from the clamping table 324 of the lock cylinder shaft 32. The lock cylinder shaft 32 can rotate in both directions, that is, the lock cylinder shaft 32 can rotate in the unlocking direction and the password changing direction. At this time, the lock cylinder 31 can be rotated to change the password. For details, please refer to Figure 11 In summary, when the password is incorrect, the locking member 50 and the lock cylinder shaft 32 are limited to cooperate to prevent the password from being changed. Only when the password is correct, the lock cylinder shaft 32 can be rotated to change the password, thereby avoiding the ambiguity of operation.

[0079] Please refer to Figure 11 The locking member 50 is provided with a positioning slot 52, and the lock cylinder shaft 32 is provided with a boss 51 which cooperates with the positioning slot 52 to drive the locking member 50 to move between the first position and the second position. The positioning slot 52 is provided with the boss 51.

[0080] In the embodiment, the lock cylinder rotating shaft 32 and the locking member 50 are vertically arranged, and one end of the locking member rotating shaft extends into the positioning groove 52 of the locking member 50 to drive the locking member 50 to move along the axial direction, thereby unlocking or locking the lock hook 20. Specifically, the lock cylinder rotating shaft 32 comprises a body, one end of the body is provided with an unlocking portion 321, a locking portion 322 and a password changing portion 323, and the other end is provided with an eccentric shaft 325, the eccentric shaft 325 is provided with a clamping table 324, the convex table 51 is arranged in the positioning groove 52, the lock cylinder 31 drives the eccentric shaft 325 to rotate, and the extension and retraction of the locking member 50 is realized.

[0081] Please refer to Figure 1 The lock also comprises a resilient member 53, one end of the locking member 50 is matched with the lock hook 20, and the resilient member 53 is clamped between the other end of the locking member 50 and the lock body 10.

[0082] In the embodiment, since the resilient member 53 is arranged, even if the password disc 41 is located at a wrong position, the lock hook 20 can be locked by pressing the lock hook 20, the lock hook 20 extrudes the resilient member 53 through the locking member 50, and the operation is convenient.

[0083] The working principle of the lock 100 will be described below:

[0084] The unlocking process is as follows: when the password disc 41 is rotated, the password disc 41 drives the password disc rotating shaft 42 to rotate together, when the correct position is reached, the limiting block 431 on the transmission rod 43 is aligned with the insertion slot 421 of the password disc rotating shaft 42, the key rotates the lock cylinder 31, the unlocking portion 321 of the lock cylinder rotating shaft 32 abuts against the transmission rod 43, the lock cylinder rotating shaft 32 drives the transmission rod 43 to move axially during the rotation, and the locking member 50 is extruded to retreat, the locking member 50 is separated from the lock hook 20, the lock hook 20 is extruded, and the unlocking is realized. It should be noted that the transmission rod 43 does not contact the password disc rotating shaft 42 in the axial direction during the axial movement of the transmission rod 43, so the password disc rotating shaft 42 cannot be driven to move. When the password is incorrect, the limiting block 431 of the transmission rod 43 is misaligned with the insertion slot 421 of the password disc rotating shaft 42, and the clamping convex 422 of the password disc rotating shaft 42 is also misaligned with the avoiding slot 11 of the lock body 10. At this time, the lock cylinder 31 is rotated, the transmission rod 43 and the password disc rotating shaft 42 cannot move backward, and the lock cannot be unlocked.

[0085] The locking process is as follows: after the lock 100 is unlocked, the key is rotated to the initial position and pulled out, the lock hook 20 is pressed, the locking member 50 moves rightward under the action of the resilient member 53, the locking member 50 enters the groove of the lock hook 20, and the lock is locked.

[0086] The changing password process: when the correct password position of the password disc 41, the key rotates the lock cylinder 31, the lock cylinder 31 drives the lock cylinder shaft 32 to rotate, the changing password position of the lock cylinder shaft 32 abuts against the transmission rod 43, the transmission rod 43 moves axially to axially contact the password disc shaft 42, and pushes the password disc shaft 42 to move backward, at this time, the clamping convex 422 of the password disc 41 is separated from the clamping groove 411 of the password disc shaft 42, the password disc 41 rotates and does not drive the password disc shaft 42 to rotate, at this time, the password is rotated to the new password to be changed, the key is rotated back and pulled out, the lock cylinder 31 drives the lock cylinder shaft 32 to return to the initial position, the transmission rod 43 and the password disc shaft 42 move forward to the initial position under the action of the transmission rod 43 spring 441 and the password disc shaft 42 in the second reset member 432 and the first reset member 423, the clamping convex 422 of the password disc shaft 42 re-enters the clamping groove 411 of the password disc 41, and the password changing is successful.

[0087] The above description is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made under the inventive concept of the present application, and direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
