The application provides a lock 100 with double locking of a password and a lock cylinder.

Referring to fig. 1, the lock 100 includes: a lock body 10; the lock hook 20 is movably arranged on the lock body 10, and the lock hook 20 is provided with a locking position and an unlocking position; a cylinder assembly 30 including a cylinder 31 rotatably provided in the lock body 10, the cylinder assembly 30 being engaged with the lock hook 20 to unlock or lock the lock hook 20, so that the lock hook 20 is switched between an unlock position and a lock position; the password assembly 40 is rotatably arranged on the lock body 10, so that the password assembly 40 can lock or release the lock cylinder 31, and when the password assembly 40 releases the lock cylinder 31, the lock cylinder 31 is rotated to unlock the lock hook 20; when the combination assembly 40 locks the lock cylinder 31, the lock cylinder 31 is rotated and the lock cylinder 31 is immobilized so that the shackle 20 is in the locked position.

According to the technical scheme, the lock cylinder 31 is locked through the password component 40, the lock cylinder 31 can lock the lock hook 20, when unlocking is needed, the lock cylinder 31 can be released only by unlocking the password component 40, then the lock cylinder 31 is rotated to enable the lock hook 20 to be in the unlocking position, and the lock 100 can be unlocked only by simultaneously unlocking the password component 40 and the lock cylinder component 30. The proposal uses the lock cylinder 31 and the coded disc 41 to perform double locking, thereby improving the safety of the lockset 100. Even if the corresponding mechanical key of the cylinder assembly 30 is lost, the lock 100 will not be opened at will; also, even if the code is known, the lock 100 cannot be opened without a mechanical key.

In order to further explain the innovative requirements of mechanical anti-misoperation locksets in an electric anti-misoperation system and solve the problem risk that a lock cylinder and a key of the mechanical anti-misoperation lockset are in unified specification, and the lockset corresponding to the lock cylinder can be opened by one mechanical key, the inventive concept of the application is explained from the following 3 angles:

(1) Intellectualization (electronization): the mechanical lock is not used, the electronic lock or the intelligent lock (such as a Bluetooth lock, an NFC lock, a fingerprint lock and the like) is used, the mechanical lock opening does not exist in the electronic lock, the traditional lock core module does not exist, and even if the mechanical lock opening exists, the non-emergency situation can not be opened. Under the condition, the misoperation-preventive locking requirement in the electric misoperation-preventive system is met, thousands of misoperation-preventive locks are often needed for a transformer substation, reliability of the electronic locks or the intelligent locks is greatly tested, the effectiveness of electronic modules such as Bluetooth, fingerprint and NFC is high, the battery electricity monitoring or maintenance cost of the locks is high, and under the application scene, the mechanical misoperation-preventive locks have obvious technical advantages.

(2) And (3) mechanical transformation: the mechanical lock is continuously used, the mechanical properties of the mechanical lock are not changed, the mechanical lock is improved, as the conception of the application is the same, a mechanical password mechanism and a locking mechanism corresponding to a limiting lock cylinder are added, the technical advantages of the traditional mechanical anti-misoperation lock are reserved, and the technical problems are also improved.

(3) Electromechanically reforming: the mechanical lockset is continuously used, an electronic module (such as Bluetooth, fingerprint identification, face recognition, NFC and the like) is added, a functional module of the mechanical lockset is reserved, and a functional module of the intelligent lockset is newly added. Although the problem of traditional mechanical mistake proofing tool to lock has been solved, this kind of product scheme cost is the highest, has traditional mistake proofing tool to lock function, has intelligent mistake proofing tool to lock performance, also has intelligent tool to lock product performance reliability problem (e.g. electronic components quality requirement is high) under the electric power mistake proofing scene of intelligent tool to lock to and product maintenance cost is high (e.g. tool to lock battery control and maintenance).

In this embodiment, the code assembly 40 limits the lock core 31 to rotate in various ways, for example, the code assembly 40 can extend into the lock body 10 to limit the lock core 31 and the lock body 10 together, so that the lock core 31 cannot rotate relative to the lock body 10 when the key is turned. In addition, a limiting component may be further disposed on the rotation shaft of the lock cylinder 31, and the rotation of the lock cylinder 31 may be limited only by limiting the rotation of the limiting component, which is not limited herein, but specific implementation manners are not limited herein.

Specifically, the lock body 10 is provided with a cavity and a lock hole 16 communicated with the cavity, the lock core assembly 30 and the code assembly 40 are both arranged in the cavity, and the lock hook 20 is movably arranged in the lock hole 16. The latch hook 20 is approximately in an inverted U shape, the latch hook 20 comprises a long end and a short end, the long end is matched with the lock core assembly 30, when the long end of the latch hook 20 is unlocked, the whole latch hook 20 pops out of the lock body 10, the short end of the latch hook 20 stretches out of the lock body 10, and the whole latch hook 20 can rotate around the long end, so that unlocking of the lock is realized.

Referring to fig. 1 and 2, the code assembly 40 includes a code disc rotating shaft 42 and a code disc 41 sleeved on the code disc rotating shaft 42, the code disc 41 drives the code disc rotating shaft 42 to rotate to release or block the code disc rotating shaft 42, so that the lock cylinder 31 is unlocked or locked, when the code disc 41 is in a correct position, the code disc rotating shaft 42 is released, and the code disc rotating shaft 42 can move relative to the code disc 41 to unlock the lock cylinder 31.

In this embodiment, the code assembly 40 includes a code disc rotating shaft 42 and a code disc 41, the code disc 41 is sleeved on the periphery of the code disc rotating shaft 42, and one end of the code disc rotating shaft 42 is matched with the lock cylinder 31, and the code assembly 40 is unlocked by limiting the rotation of the code disc 41 by the code disc rotating shaft 42.

Referring to fig. 2, in general, the outer ring of the code disc 41 has 0 to 9 ten numbers to indicate different code numbers, and the code disc 41 is provided with a plurality of code discs 41 to increase the difficulty of unlocking the code, when all code discs 41 are located at the correct positions, i.e. when all numbers on the code discs 41 are correct, the code disc 41 can unlock the code disc rotating shaft 42, and at this time, the code disc rotating shaft 42 moves relative to the code discs 41, thereby releasing the lock core 31.

It should be noted that, after the code disc rotating shaft 42 moves relative to the code disc 41, the code disc rotating shaft 42 does not limit the code disc 41 any more, and at this time, the code disc 41 can rotate relative to the code disc rotating shaft 42, so that the code can be changed. That is, when password change is required, password component 40 needs to be unlocked first.

Referring to fig. 1 and 6, the code assembly 40 further includes a limiting member 44, a limiting groove 412 is formed on the periphery of the code disc 41, and two ends of the limiting member 44 are abutted against the limiting groove 412 and the lock body 10.

In order to prevent random rotation of the code disc 41 after unlocking, a limit groove 412 is formed in the outer ring of the code disc 41, each limit groove 412 is formed between two adjacent numbers, when the limit piece 44 is clamped in the corresponding limit groove 412, the code disc 41 cannot rotate randomly, meanwhile, the situation that after the code is changed, the code disc 41 rotates randomly to cause that an actual code is inconsistent with a code originally designed by a user is avoided, the code assembly 40 cannot be unlocked, and therefore user experience is reduced.

Specifically, the limiting member 44 is disposed in the cavity of the lock body 10, the limiting member 44 includes a spring 441 and a steel ball 442, one side of the steel ball 442 is elastically abutted against the spring 441, the other side of the steel ball 442 is in contact with the periphery of the code disc 41, the spring 441 provides the power for the steel ball 442 to move toward the code disc 41, and when the code disc 41 needs to rotate, the steel ball 442 is extruded, so that the spring 441 is compressed. When the steel ball 442 is clamped in the limiting groove 412, the code wheel 41 will not rotate at will. In addition, during the rotation of the code disc 41, the steel balls 442 contact with the concave-convex portions of the outer periphery of the code disc 41, and give a certain hand feel to the user, so as to prompt the user of the number of digits to rotate.

Referring to fig. 2, 6 and 7, the code disc rotating shaft 42 is provided with a clamping protrusion 422, the code disc 41 is provided with a clamping slot 411 corresponding to the clamping protrusion 422, the code disc 41 drives the code disc rotating shaft 42 to rotate through the cooperation of the clamping protrusion 422 and the clamping slot 411, the lock body 10 is provided with a position avoiding slot 11 corresponding to the clamping protrusion 422, and when the code disc 41 is in a correct position, the position avoiding slot 11 is aligned with the clamping protrusion 422 so as to release the code disc rotating shaft 42.

In this embodiment, when the position of the code wheel 41 is wrong, the locking protrusion 422 of the code wheel rotating shaft 42 is dislocated with the avoiding slot 11 of the lock body 10, and at this time, the code wheel rotating shaft 42 cannot move axially, that is, the lock cylinder 31 cannot be released, and the axial movement of the code wheel rotating shaft 42 is limited by the lock body 10. In addition, the locking protrusion 422 of the code disc rotating shaft 42 is locked with the locking slot 411 in the code disc 41 in the circumferential direction by default, so that the code disc rotating shaft 42 is driven to rotate by the code disc 41.

In general, the circumference of the code disc 41 is provided with 0 to 9 numbers, so that ten corresponding clamping slots 411 are formed in the code disc 41, and one clamping protrusion 422 is formed in the code disc rotating shaft 42, and the clamping protrusion 422 of the code disc rotating shaft 42 is matched with one clamping slot 411 of the code disc 41 under default condition, after the code, the code disc rotating shaft 42 can return to one clamping slot 411.

Referring to fig. 5, 6 and 7, the lock cylinder assembly 30 includes a lock cylinder rotating shaft 32 in driving connection 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 position of the code wheel 41 is correct, the lock cylinder 31 drives the lock cylinder rotating shaft 32 to rotate, and the lock cylinder rotating shaft 32 is switched from the locking portion 322 to the unlocking portion 321 to the code wheel rotating shaft 42 to push the code wheel rotating shaft 42 to move, and the lock cylinder rotating shaft 32 releases the lock hook 20.

In this embodiment, when the password is correct, the lock core rotating shaft 32 is no longer limited by the lock body 10, the password disc rotating shaft 42 has an axially moving space, and at this time, the lock core rotating shaft 32 can rotate, so that the key can rotate the lock core 31, and the lock core 31 releases the lock hook 20, thereby unlocking the lock. At this time, when the code is located at the correct position, the lock cylinder rotating shaft 32 is rotated to the unlocking position to push the code disc rotating shaft 42 to move, i.e. the code disc 41 can be rotated to change the code.

Referring to fig. 6 and 8, the code assembly 40 further includes a transmission rod 43, the code disc rotating shaft 42 is sleeved on the transmission rod 43, the code disc 41 and the code disc rotating shaft 42 can rotate relative to the transmission rod 43, the lock cylinder rotating shaft 32 is further provided with a code changing portion 323, when the code disc 41 is located at a correct position, the lock cylinder 31 rotates to drive the lock cylinder rotating shaft 32 to rotate, and the lock cylinder rotating shaft 32 is switched from the abutting connection of the unlocking lock portion and the transmission rod 43 to the abutting connection of the code changing portion 323 and the transmission rod 43 so as to drive the transmission rod 43 and the code disc rotating shaft 42 to axially move.

Preferably, the code assembly 40 further includes a transmission rod 43, the code disc 41 and the code disc rotating shaft are both in an annular arrangement, the transmission rod 43 movably penetrates through the code disc rotating shaft 42, the code disc 41 is sleeved outside the code disc rotating shaft 42, one end of the transmission rod 43 is matched with the lock cylinder 31, when the code disc 41 rotates to a correct position, the code changing part 323 of the lock cylinder rotating shaft 32 is pushed to axially move together with the code disc rotating shaft 42 in the process of abutting the transmission rod 43, and at the moment, the code disc 41 can be independently rotated to change the code.

It should be noted that, when the unlocking position of the lock core rotating shaft 32 abuts against the transmission rod 43, only the transmission rod 43 can be pushed to move axially, and only the unlocking function can be realized at this time, but the password changing function cannot be realized. By the arrangement, different functions are realized when different parts (the unlocking part 321, the locking part 322 and the password changing part 323) of the lock cylinder rotating shaft 32 are abutted with the transmission rod 43, so that user experience is optimized.

It can be understood that, although the password can be changed without the transmission rod 43, the password can be unlocked or changed at this time, in this embodiment, the transmission rod 43 is provided, when the unlocking position of the lock cylinder rotating shaft 32 is abutted 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 bit of the lock cylinder rotating shaft 32 is abutted with the transmission rod 43, the transmission rod 43 and the password disc rotating shaft 42 are pushed to move simultaneously, and the password disc 41 can rotate, so that password changing can be realized. Different parts (an unlocking part 321, a locking part 322 and a password changing part 323) of the lock cylinder rotating shaft 32 are enabled to realize different functions when being abutted with the transmission rod 43, so that user experience is optimized.

Referring to fig. 5, the periphery of the lock cylinder rotating shaft 32 is a password changing portion 323, a first groove and a second groove are further formed on the periphery of the lock cylinder rotating shaft 32 to form an unlocking portion 321 and a locking portion 322, respectively, and the depth of the first groove is smaller than that of the second groove.

In this embodiment, the matching position of the lock cylinder rotating shaft 32 and the transmission rod 43 has a radian change, and the periphery of the lock cylinder rotating shaft 32, the first groove and the second groove are respectively a password changing portion 323, an unlocking portion 321 and a locking portion 322. Different parts are matched with the transmission rod 43, and the distance for pushing the transmission rod 43 to move is different.

Specifically, when the lock portion 322 (second groove) abuts against the transmission lever 43, the transmission lever 43 is in an extended state, i.e., a position close to the lock cylinder 31; when the unlocking portion 321 (first groove) abuts against the transmission rod 43, the unlocking shaft pushes the transmission rod 43 to move a first distance away from the lock core 31 because the depth of the first groove is smaller than that of the second groove; when the password changing portion 323 (the periphery of the lock cylinder rotating shaft 32) abuts against the transmission rod 43, the unlocking rotating shaft pushes the transmission rod 43 and the password disc 41 to rotate to move a second distance away from the lock cylinder 31, and the second distance is larger than the first distance. In practice, as long as the lock cylinder rotating shaft 32 rotates, the distance for the transmission rod 43 to move is three, and the three structures of the protrusion, the periphery and the groove can be realized, and the peripheral and two grooves can also be adopted, which is not limited herein.

Referring to fig. 2 and 8, the transmission rod 43 is convexly provided with a limiting block 431, the inner side wall of the code 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 code disc rotating shaft 42, the depth of the first groove is greater than that of the slot 421, when the position of the code disc 41 is correct, the limiting block 431 is aligned with the slot 421, when the unlocking position is abutted with the transmission rod 43, the lock cylinder rotating shaft 32 pushes the transmission rod 43 to move, when the unlocking position is abutted with the transmission rod 43, the limiting block 431 is abutted with the slot 421, and the transmission rod 43 drives the code disc rotating shaft 42 to move synchronously.

Since the slot 421 is formed in the inner side wall of the code disc shaft 42, and the depth of the first groove is greater than the depth of the slot 421, when the unlocking portion 321 (the first groove) abuts against the driving rod 43, the driving rod 43 moves a distance, but the distance moved at this time is insufficient to overcome the depth of the slot 421, that is, the driving rod 43 moves backward at this time, but does not contact the code disc shaft 42 in the axial direction, so that the code disc shaft 42 is not driven to move. When the distance of the movement of the stopper 431 is equal to the depth of the slot 421 in the process of pushing the transmission rod 43 to move by abutting the password changing portion 323 with the transmission rod 43, the transmission rod 43 axially contacts the password disc rotating shaft 42 and pushes the password disc rotating shaft 42 to synchronously move.

Referring to fig. 3, the lock body 10 is provided with a mounting groove 12, the code wheel 41 is disposed in the mounting groove 12, the lock body 10 is further provided with a chute 13 vertically communicated with the mounting groove 12, and the transmission rod 43 and the code wheel rotating shaft 42 are movably disposed in the chute 13 in a penetrating manner.
