DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0024] The specific embodiments are given below.

[0025] Please refer to Figures 1-7The utility model discloses a suitcase coded lock, including coded lock body 1, the coded lock body 1 is assembled with coded wheel subassembly 2, coded wheel subassembly 2 includes coded wheel 3, wheel hub 4, axle 5, the coded wheel 3 includes inner wheel 301, and the outer wheel 302 of rotation connection with inner wheel 301 through bearing, the inner wall of outer wheel 302 is fixedly provided with a plurality of obtuse angle lug 3022 in annular array, the outer wall of inner wheel 301 is fixedly provided with a plurality of obtuse angle recess 3012 of cooperation with obtuse angle lug 3022 in annular array, be provided with coded number groove 3021 on outer wheel 302, the inner wall of inner wheel 301 is set with a plurality of recess 3011, the outer diameter of wheel hub 4 is fixedly provided with a plurality of protruding 401 with recess 3011 cooperation, the inner wall of wheel hub 4 is fixedly provided with limit block 402, the outer wall of axle 5 is set with the unlocking limit slot 501 of cooperation with limit block 402 and the direction with axle 5 central axis parallel, the outer wall of axle 5 still is set with annular limit slot 502 with limit block 402 cooperation and the direction with axle 5 central axis vertical, the movable slot 6 of coded lock body 1 is set up at coded wheel 3, the movable slot 6 is movably provided with movable rod 7, the lock pin 8 of fixed setting is provided with on movable rod 7, the lock slot 9 of cooperation with lock pin 8 is set up on one side of inner wheel 301, the operating block 10 of fixed setting is provided with on movable rod 7, the cover plate 11 of cooperation with movable slot 6 is assembled on coded lock body 1 at movable slot 6, the movable hole 12 for operating block 10 movement is set up on cover plate 11.In operation, in the initial state, the limiting block 402 of the hub 4 is located in the annular limiting groove 502 of the axle 5, at this time, the password wheel assembly 2 is in the locked state, due to the confinement of the annular limiting groove 502, the hub 4 cannot move freely in the axial direction, thereby limiting the unlocking movement of the password wheel 3 closely connected with the hub 4, ensuring the safety of the password lock when it is closed, when it is necessary to unlock the password lock for unlocking operation, the user rotates the password wheel 3, and through the password wheel 3 rotating to the correct password, the limiting block 402 of the hub 4 is gradually aligned with the unlocking limiting groove 501 of the axle 5, once the limiting block 402 completely enters the unlocking limiting groove 501, the password wheel 3 is released from the limitation of the annular limiting groove 502, at this time, the password wheel 3 can freely move in the path defined by the unlocking limiting groove 501 in the axial direction, realizing the unlocking of the password lock, when it is necessary to change the password, the user first unlocks the password wheel 3 to the above-mentioned freely movable state, then pushes the operating block 10 with the fingers, the operating block 10 drives the movable rod 7 to move smoothly in the movable slot 6, prompting the lock pin 8 to be inserted into the lock slot 9, accurately limiting the angle of the inner wheel 301, due to the ratchet structure characteristics of the obtuse angle protrusion 3022 and the obtuse angle recess 3012 between the outer wheel 302 and the inner wheel 301, in the normal state, the two are relatively static, but when the user slightly rotates the outer wheel 302 with force, the engagement force between the two can be overcome, so that the outer wheel 302 rotates relative to the inner wheel 301, thereby adjusting the password number to the preset new position, after completing the password change, the user operates the operating block 10 again, so that the lock pin 8 is pulled out of the lock slot 9, and the password wheel 3 returns to the free rotating state, the new password setting is completed and takes effect; compared with the complex and cumbersome password change process of the traditional password lock, the utility model provides a very simple and intuitive password modification method for the user, through the linkage of the operating block 10, the movable rod 7 and the lock pin 8, matched with the ratchet structure of the outer wheel 302 and the inner wheel 301, the user only needs to simply push the operating block 10 to insert the lock pin 8 to limit the inner wheel 301, and then easily rotate the outer wheel 302 to complete the password reset, the whole process does not need to rely on additional tools, and can be smoothly completed by single-handed operation, greatly saving the time and energy of the user, whether in the process of hurriedly changing the password in the journey or frequently changing the password in daily life to improve the safety, it can be easily coped with.

[0026] Further, the password digital slot 3021 is filled with a luminescent material; in operation, in a light environment, such as a sunny outdoor, indoor bright light illumination, the luminescent material is like a sharp light energy collector, efficiently absorbs and stores photon energy, when the environment light suddenly becomes dark, into the night travel, dim warehouse and other low light or no light scene, the energy stored in the luminescent material is activated, according to the specific energy level transition law, the luminescent material releases photons at a stable and slow rate, so that the numbers in the password digital slot 3021 are lit, clear and eye-catching, ensuring that the user can smoothly operate the password, effectively solving the problem of password operation in low light environment, effectively avoiding password misjudgment, lock obstruction and other inconveniences caused by dim light, providing great convenience for people traveling at night, emergency access to luggage.

[0027] Further, the circumference of the outer wheel 302 is equidistantly provided with a V-shaped groove 13 corresponding to the password digital slot 3021; in operation, when the user rotates the outer wheel 302 to set the password or perform the unlocking operation, the fingers will naturally fit the V-shaped groove 13, the V-shaped groove 13 provides a stable force point for the fingers during the entire rotation process, significantly enhances the friction between the fingers and the outer wheel 302, effectively prevents the fingers from slipping, and ensures the continuity and stability of the operation, from the perspective of operation experience, greatly improves the usability of the password wheel.
