The lock cylinder 23 is formed with a cavity at the end close to the side wall of the lock box 11, and a connecting rod 233 is arranged in the cavity and extends out of the cavity to abut against the side wall of the lock box 11, so that the lock cylinder 23 is sleeved on the connecting rod 233 and moves horizontally. A second spring 234 is arranged between the connecting rod 233 and the cavity to reset the lock cylinder 23 under the elastic force after the movement of the lock cylinder 23.

[0038] The lock structure 3 is arranged in the knob sleeve 24. The knob sleeve 24 is arranged in the circular hole 112 and is provided with a through lock hole 241 corresponding to the abutting position of the lock cylinder 23. The lock cylinder 23 is inserted into the lock hole 241 to lock the knob sleeve 24. The knob sleeve 24 is provided with a through reset hole 242 at the position 90° counterclockwise to the lock hole 241. The edge lines of the lock hole 241 and the reset hole 242 are both provided with arc-shaped inclined surfaces to allow the lock cylinder 23 to move along the inclined surfaces between the lock hole 241 and the reset hole 242. The inner surface of the knob sleeve 24 is provided with a plurality of locking holes corresponding to the lock hole 241, and a plurality of locking pins 243 are slidably arranged in the locking holes. One end of the locking pin 243 protrudes out of the locking hole to lock the key lock structure 3.

[0039] Referring to Figure 2 , Figure 6 , in order to facilitate the identification of the locking or unlocking state of the knob sleeve 24, the lock box 11 is provided with a stop piece 113 corresponding to the circular hole 112. The stop piece 113 is a ring-shaped protrusion with a gap extending out of the lock box 11. One end of the stop piece 113 is located close to the code wheel 21, and the other end is located at the position 90° clockwise to the one end.

The pointer 244 is located in the gap of the stop piece 113 and is limited to rotate in the gap of the stop piece 113.

[0040] The password wheel 21 rotates to drive the password disc 22 to rotate synchronously, drive the through port of the lock core hole 224 to correspond to the core block 232, so that the core block 232 of the password lock core 23 is not blocked by the password disc 22, the password lock core 23 can move in the horizontal direction, and the locking of the knob sleeve 24 is released. Then rotate the knob sleeve 24, the password lock core 23 abuts in the lock port 241 of the knob sleeve 24 and moves along the inclined surface, the arc-shaped inclined surface pushes the password lock core 23 to move in the horizontal direction, drives the core block 232 to move synchronously, and the core block 232 moves into the through port of the lock core hole 224.

[0041] With reference to Figure 3 、 Figure 6 、 Figure 7 The key lock structure 3 is rotatably arranged in the knob sleeve 24 and is used to release the locking of the cabinet. The key lock structure 3 comprises a key lock core 31, a lock pin 32 and an unlocking block 33. The key lock core 31 is rotatably arranged in the knob sleeve 24 and is horizontally arranged with the password lock structure 2 at an end of the key hole 311 arranged away from the rear cover 12. A plurality of lock pin holes are axially arranged on the outer circumferential surface of the key lock core 31 and are communicated with the key hole 311. A plurality of lock pins 32 are slidably arranged in the lock pin holes. Each lock pin 32 abuts against the locking pin 243. The locking pin 243 abuts against the lock pin 32 and protrudes into the key hole 311, so that the locking pin 243 is inserted into the lock pin hole to block the rotation of the key lock core 31. The unlocking block 33 is arranged at an end of the key lock core 31 away from the key hole 311 and abuts against the surface of the rear cover 12.

[0042] Further, the key lock core 31 is further provided with a reset slot 312 corresponding to the reset hole 242 of the knob sleeve 24. The reset slot 312 and the reset hole 242 are provided with the same arc-shaped inclined surface, so that the password lock core 23 abuts in the reset slot 312 and moves along the inclined surface to reset.

[0043] The key inserted into the key hole 311 can drive the lock pin 32 to move. The lock pin 32 drives the locking pin 243 to slide out of the lock pin hole, so that the locking pin 243 releases the locking of the key lock core 31. The key lock core 31 rotates to drive the unlocking block 33 to rotate synchronously, thereby releasing the locking of the cabinet.

[0044] With reference to Figure 3 、 Figure 4 、 Figure 8 、 Figure 9The password resetting structure 4 is arranged in the lock box 11 and cross-connected with the password lock structure 2, and comprises a plurality of resetting members 41 and a driving member 42. The plurality of resetting members 41 are arranged as a spiral elastic metal coil and installed beside each clamping disc 223. Each resetting member 41 is connected with a clamping post 411 at one end of the inner ring, and the clamping post 411 abuts against the surface of the clamping disc 223. In the embodiment, the surface of the clamping disc 223, which is connected with the clamping post 411, is provided with a plurality of arc-shaped grooves 2232. Each groove 2232 corresponds to each number on the password wheel 21 and is arranged in a ring shape. One of the grooves 2232 corresponds to the through hole of the lock cylinder hole 224, and the groove 2232 is deeper than the remaining grooves 2232 and is used for accommodating the clamping post 411, thereby driving the password disc 22 to rotate. The driving member 42 is arranged between the password lock structure 2 and the back cover 12 and located in the lock box 11. The driving member 42 comprises two rotating shafts 421, a transmission belt 422 and a pushing block 423. The two rotating shafts 421 are arranged in parallel in the lock box 11. The transmission belt 422 is sleeved on the two rotating shafts 421, so that the two rotating shafts 421 rotate synchronously. One end of the resetting member 41 located at the outer ring is connected to one of the rotating shafts 421, and the rotating shaft 421 rotates to wind the resetting member 41. The pushing block 423 is connected with the transmission belt 422 and extends outward through the movable slot 121 formed in the corresponding position of the back cover 12. The pushing block 423 moves along the movable slot 121 to drive the transmission belt 422 to transmit.

[0045] Further, in order to make the rotating track of the clamping post 411 around the password lock cylinder 21 correspond to the plurality of grooves 2232 arranged in a ring shape, the password resetting structure 4 is further provided with a plurality of track rings 43. The track rings 43 are installed on the side of the resetting member 41 away from the clamping disc 223 and are fixed to the lock box 11. The track rings 43 are provided with rotating grooves 431 corresponding to the plurality of grooves 2232, and the clamping post 411 is inserted into the rotating grooves 431 to rotate.

[0046] In order to fix the moved pushing block 423 and avoid the resetting member 41 from being wound and recovered under the elastic action, the password resetting structure 4 further comprises a clamping member 44. The clamping member 44 is parallel to the back cover 12, arranged in the lock box 11 and corresponds to the password lock structure 2. One end of the clamping member 44 abuts against the key lock cylinder 31. The key lock cylinder 31 is provided with a track groove 313 corresponding thereto. The key lock cylinder 31 rotates to drive the clamping member 44 to move along the track groove 313 and abut against the plurality of password wheels 21, so as to increase the friction of the password wheel 21 rotating, and make the resetting member 41 drive the password disc 22 to rotate without driving the password wheel 21 to rotate synchronously. The clamping member 44 is further provided with a bevel gear rack 441 located beside the transmission belt 422. When the bevel gear rack 441 is close to the password lock structure 2, the bevel gear rack 441 cooperates with the pushing block 423. The pushing block 423 is correspondingly provided with an elastic tooth block 424. The tooth block 424 moves vertically and unidirectionally along the bevel gear rack 441.

[0047] The double unlocking type password lock provided by the application has the specific principle as follows:

[0048] In the initial state of the password lock, the password lock core 23 is inserted into the lock opening 241 to abut against the key lock core 31, and the key lock core 31 abuts against the password lock core 23 to make the second spring 234 in the compressed state. The password lock core 23 drives the clamping disc 223 to move through the first spring, so that the clamping groove 2231 of the clamping disc 223 is completely matched with the clamping block 211. At this time, the clamping column 411 abuts against one of the grooves 2232 of the clamping disc 223;

[0049] When the password lock structure 2 is used to unlock, the password wheel 21 is rotated to drive the password disc 22 to rotate synchronously, and the grooves 2232 on the clamping disc 223 abut against the clamping column 411 in turn to ensure that the stop position of each number is accurate after rotation. All the password wheels 21 are rotated to the correct password position. Then the knob sleeve 24 is rotated to drive the lock opening 241 to rotate synchronously, so that the password lock core 23 is pushed by the inclined surface of the lock opening 241, the password lock core 23 moves to drive the core block 232 to move synchronously, and the core block 232 is inserted into the through port of the lock core hole 224. At the same time, the knob sleeve 24 is rotated to drive the key lock core 31 to rotate synchronously by 90°, the key lock core 31 drives the unlocking block 311 to rotate to release the locking of the cabinet body, and the reset groove 312 of the key lock core 31 corresponds to the password lock core 23, the second spring 234 pushes the password lock core 23 to move and insert into the reset groove 312;

[0050] At this time, the password can be reset, the password lock core 23 drives the core block 232 to move to the outside of the lock core hole 224, synchronously drives the blocking ring 231 to move, and the blocking ring 231 pushes the password disc 22 to move synchronously through the first spring, so that the clamping disc 223 moves to disengage from the matching with the clamping block 211. The moving clamping disc 223 is close to the reset member 41 and is further abutted by the clamping column 411. If the clamping column 411 abuts against the groove 2232 corresponding to the through port of the lock core hole 224, the clamping disc 223 completely disengages from the matching with the clamping block 211, the reset member 41 is wound to drive the clamping column 411 to rotate, synchronously drives the clamping disc 223 to rotate, and further drives the password disc 22 to rotate synchronously, so that the through port of the lock core hole 224 is rotated to correspond to the core block 232 again. If the clamping column 411 abuts against the remaining grooves 2232, the clamping disc 223 is further abutted by the clamping column 411, so that the clamping groove 2231 is not completely disengaged from the clamping block 211. The reset member 41 is wound to drive the clamping column 411 to rotate, the clamping column 411 passes through the groove 2232 to enter the adjacent groove 2232, and then abuts against the groove 2232 corresponding to the through port of the lock core hole 224. Then the password disc 22 is rotated as described above.

[0051] When the key lock structure 3 is used for unlocking, the key is inserted into the key hole 311, the key pushes the lock 32 to move, the lock 32 pushes the locking pin 243 to move out of the key lock core 31, the key drives the key lock core 31 to rotate 90°, and then drives the unlocking block 33 to rotate synchronously, thereby releasing the locking of the cabinet. At the same time, the password can be reset according to the above steps.

[0052] After the password is reset, the key lock core 31 is reset, the password lock core 23 is pushed to move and reset the second spring 234, the blocking ring 231 is driven to reset synchronously, and then the first spring is used to reset the password disc 22 and re-coordinate with the password wheel 21. At the same time, the key lock core 31 drives the clamping part 44 to reset, thereby releasing the resistance to the dial block 423, and the dial block is moved to the original position under the elastic force of the reset part 41.

[0053] The double unlocking type password lock provided by the application sets the password wheel structure and the key lock structure, so that the cabinet can be unlocked by using the password or the key, then the reset part is set between the password wheels, and the reset part drives the password wheels to rotate to reset the password by winding the reset part through the rotating shaft. The double unlocking type password lock has simple structure and greatly improves the convenience of password resetting.

[0054] The above-mentioned embodiments only express the implementation of the application, but cannot be interpreted as the limitation of the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which belong to the protection scope of the application.
