[0034] A lock with identification function in this embodiment, such as Figures 1 to 5 As shown, it includes a lock shell 1, a password component 2, a key component 3 and a lock rope 5. The lock shell 1 is provided with a lock hole 11. The password component 2 and the key component 3 are installed in the lock shell 1. One end of the lock rope 5 is fixed in the lock shell 1, and the other end of the lock rope 5 can be inserted into the lock hole 11 in a pluggable manner. The password component 2 and the key component 3 can clamp the end of the lock rope 5 to achieve locking. When the correct password is entered into the password component 2 or the correct key is inserted into the key component 3, the limit at the end of the lock rope 5 can be released to achieve unlocking.

[0035] In this embodiment, the password assembly 2 is located at the lock hole 11, and the key assembly 3 is located at the end of the password assembly 2. The password assembly 2 includes a center rod 21, a plurality of password wheels 22 and a code adjustment wheel 23. The plurality of password wheels 22 are rotatably mounted in parallel on the lock housing 1 and partially exposed. The code adjustment wheels 23 are inserted into the password wheels 22 one by one. The code adjustment wheels 23 and the password wheels 22 are mutually limited in the circumferential direction to rotate together. The center rod 21 passes through the plurality of code adjustment wheels 23 to limit the end of the lock rope 5 inserted into the lock housing 1 to achieve locking; the inner side of each code adjustment wheel 23 is respectively provided with an unlocking groove 231, and the outer side wall of the center rod 21 is provided with a plurality of unlocking protrusions 211 that are axially aligned with each other. When the password of any password wheel 22 is wrong, its unlocking protrusion 211 is staggered with the unlocking groove 231, and the center rod 21 and the code adjustment wheel 23 cannot move relative to each other in the axial direction, so as to achieve locking. When the code wheel 22 rotates to a correct code, each unlocking protrusion 211 of the center rod 21 is aligned with each unlocking groove 231 of the code adjustment wheel 23, so that the center rod 21 can move axially to release the restriction on the lock rope 5.

[0036] In this embodiment, the key assembly 3 includes a lock core 31 and a shifting block 32. The outer end of the lock core 31 is exposed outside the lock housing 1. The shifting block 32 is installed at the inner end of the lock core 31 and rotates together with it. An intermediate seat 4 is provided between the shifting block 32 and the innermost coding wheel 23. The intermediate seat 4 abuts against the shifting block 32 and the coding wheel 23 respectively. The coding wheel 23 can axially move relative to the password wheel 22. A V-shaped relief groove 321 is provided on the top side edge of the shifting block 32, and a V-shaped relief boss 41 is provided at the end of the intermediate seat 4. When the key is in the locked state, the relief groove 321 and the relief boss 41 are staggered; when the key is in the unlocked state, the relief boss 41 is inserted into the relief groove 321, and the intermediate seat 4 moves towards the shifting block 32, so that the coding wheel 23 and the central rod 21 move integrally to unlock.

[0037] Of course, in practice, the positions of the relief groove 321 and the relief boss 41 can be exchanged, that is, one of the intermediate seat 4 and the shifting block 32 is provided with the relief groove 321, and the other is provided with the relief boss 41, as long as the shifting block 32 and the intermediate can be in concave-convex engagement and approach each other when the key is unlocked.

[0038] In this embodiment, a plurality of axial orientation bars 232 are provided on the outer side of the coding wheel 23, and a plurality of axial orientation grooves 221 are provided on the outer side of the password wheel 22. The plurality of orientation bars 232 are embedded in the plurality of orientation grooves 221. In this way, the coding wheel 23 and the password wheel 22 are circumferentially limited and rotate together, and can move relative to each other axially. Specifically, a blocking protrusion 233 for restricting its axial stroke is further provided on the outer side of the coding wheel 23.

[0039] In this embodiment, the lock further includes an identification block 6. The identification block 6 is provided with an unlocking mark 61. The lock housing 1 is provided with an observation port 12. After the key assembly 3 unlocks, it can drive the identification block 6 to shift and align with the unlocking mark to the observation port 12.

[0040] In this embodiment, a stop groove 42 is left on the outer side of the intermediate seat 4. The identification block 6 is provided with an extension 62 extending into the stop groove 42. The stop groove 42 leaves a space for the extension 62 to move axially. After the key is unlocked, the intermediate seat 4 abuts against the extension 62 and moves it downward; after the key is locked, the extension 62 remains at the position where it abuts against the top surface of the shifting block 32 after moving downward; in the state where the password is correct, when an external force presses the lock core 31 inward, it can drive the lock core 31, the shifting block 32, the intermediate seat 4 and the coding wheel 23 to move axially, and the shifting block 32 abuts against the extension 62 and moves it upward.

[0041] Specifically, a positioning groove 63 is provided on the side of the identification block 6, and a positioning protrusion is provided inside the lock housing 1 to cooperate with the positioning groove 63. After the key assembly 3 unlocks, the positioning groove 63 cooperates with the positioning protrusion to keep the identification block 6 in the shifted position.

[0042] Specifically, the unlocking identifier 61 is a pattern, concave-convex texture or color provided on the side of the recognition block 6. Any signal that can be observed and recognized by the human eye is acceptable.
