Background

Public facilities in public places, such as temporary lockers, shared electronic devices or vehicles, require temporary locks for locking, for example, temporary lockers are used for storing personal articles, and cabinet locks are generally required to be configured to ensure property safety. Conventional cabinet locks are key locks, and when the number of cabinets is large, management of a plurality of keys is a difficult problem. For this reason, some occasions gradually replace the key lock with a combination lock.

Regarding the temporary locker, the reasonable use mode of the coded lock is that the user of the locker sets the codes by himself, so that the risk of property loss caused by using public codes can be avoided. Because the password is 'disposable', after unlocking and taking the article by using the password set by the user, the user generally needs to reset the password set by the user to the initial password (such as '0000') according to the related management rule of the public place, so that the next user can conveniently set the password by himself.

However, the operation of resetting the password is limited by the corresponding structure of the conventional coded lock, and the user is required to do additional actions beyond the unlocking operation, such as rotating the unlocking knob to a larger angle, and even additionally arranging mechanisms such as keys to realize the function of resetting the password. Some users may forget to reset the password, either intentionally or unintentionally, thereby affecting the use of the locker by the later user and also causing inconvenience to the management of the locker. In addition, for most coded locks, after a user sets a code by himself, the code is not automatically scrambled, and the user is required to manually scramble the displayed code, so that the risk of code leakage exists.

The invention also includes a messy code deflector 90 and a third return spring 100; the messy code shifting lever 90 is matched in the lock shell 1 in a sliding way along the axial direction of the lock shaft 4 and is movably matched with the rotation stopping sliding block 8; the stop slide block 8 is driven to separate from the character wheel 2 when the messy code deflector 90 moves axially, and the messy code deflector 90 and the reset deflector 10 are respectively abutted against opposite sides of the switch 20, namely, the switch 20 is designed with two directions when being stirred, the reset deflector 10 is pushed when being stirred forward (namely, towards the unlocking direction), and the messy code deflector 90 is pushed when being stirred backward (namely, towards the locking direction). After the user sets the password, the user can drive the code-scrambling shifting lever 90 to axially move through the toggle switch 20, so that code scrambling is realized, and the possible leakage risk of the set password is avoided. In other embodiments, the switch 20 may be divided into two: the unlocking switch and the messy code switch are respectively pressed/toggled in two directions so as to respectively realize the functions of unlocking, resetting the password and locking the automatic messy code.

Further, a second guiding inclined plane 901 is arranged on one surface of the code disorder deflector 90 facing the rotation stop slide block 8; the second inclined side surface 83 is arranged at the position of the rotation stopping slide block 8 opposite to the second guiding inclined surface 901; when the mess code deflector 90 moves axially, the second guide inclined plane 901 abuts against the second inclined side surface 83 and pushes the rotation stopping slide block 8 to compress the rotation stopping spring 9, so that the rotation stopping slide block 8 resists the elasticity of the rotation stopping spring 9 to separate from the character wheel 2.

The working principle of the present invention is explained below.

Referring to fig. 12 to 15, in combination with the constructional details of the other figures, the locked state of the invention:

the character wheel 2 drives the bush 3 to rotate together, when the character wheel 2 is in an incorrect password position, the second notch 32 of the bush 3 cannot be aligned with the second lug 41 of the lock shaft 4, and the first notch 31 of the bush 3 cannot be aligned with the first lug 122 of the second shell 12; when the switch 20 is pressed/toggled, the switch 20 drives the lock shaft 4 to move in the unlocking direction, and at this time, the first protrusion 122 is not aligned with the first notch 31, the second protrusion 41 is not aligned with the second notch 32, so that the second protrusion 41 abuts against the outer wall of the bushing 3, and the outer wall of the bushing 3 abuts against the first protrusion 122, and therefore the lock shaft 4 cannot move, and the lock is in the locked state.

Referring to fig. 16-19, in combination with the structural details of the other figures, the unlocked state of the present invention:

when each character wheel 2 rotates to the correct password position, the second lug 41 of the lock shaft 4 is aligned with the second notch 32 of the bush 3, the first notch 31 of the bush 3 is aligned with the first lug 122 of the second shell 12, and the limit on the lock shaft 4 is released; pressing/toggling the switch 20 can drive the lock shaft 4 to move in the unlocking direction, thereby completing the unlocking action; when unlocking, the retainer 5 is carried by the switch 20 to move together, and the retainer 5 drives the bush 3 to move; when the switch 20 moves to a certain travel, the switch 20 contacts with the reset deflector rod 10, and when the reset deflector rod 10 is not moved, the sliding stop 70 is separated from the limit of the switch 20 and bounces under the action of the stop spring 80; when the finger applies force, the position is smoothly crossed due to the inertia action until the lockset enters a password resetting state.

Referring to fig. 20 to 23, in combination with the structural details of the other drawings, the reset password state of the present invention:

pressing/toggling the switch 20 to the limit position, the switch 20 drives the reset deflector 10 to move, because the first guide inclined plane 101 is attached to the first inclined side face 8282, when the reset deflector 10 moves, the first guide inclined plane 101 presses the first inclined side face 8282, so that the rotation stop slider 8 overcomes the elasticity of the rotation stop spring 9 and moves in the direction away from the character wheel 2; at this time, the positioning pawl 81 of the rotation stopping slider 8 moves away from the rotation stopping groove 21 of the character wheel 2, the rotation stopping slider 8 and the character wheel 2 are in a separated state, and the character wheel 2 is reset to a state of an initial state "0" by the magnetic force between the first magnet 6 and the second magnet 7

Referring to fig. 16 to 19, in combination with the structural details of the other drawings, the present invention sets the password state:

releasing the switch 20, and resetting the deflector rod 10 to rebound under the action of the first reset spring 50, so that the switch 20 is forced to move back together, and when the switch 20 is retracted to the position of the unlocking state, the sprung slider stop 70 is blocked and cannot continue to retract; the retainer 5 moves back under the action of the second return spring 60, and the bush 3 is retracted together by the retainer 5; at this time, the limit protrusion 33 of the bushing 3 is separated from the limit recess 23 of the word wheel 2, and the word wheel 2 and the bushing 3 do not rotate synchronously, because the first protrusion 122 of the second housing 12 is in the first notch 31 of the bushing 3, the bushing 3 cannot rotate, so that the bushing 3 can be ensured to be fixed when the word wheel 2 rotates, and the problem that the bushing 3 is driven by the word wheel 2 to lose accurate positioning under friction force is solved.

When the reset deflector rod 10 is at the position, the reset deflector rod 10 is just separated from the first inclined side face 8282 of the rotation stopping slide block 8, the rotation stopping slide block 8 moves towards the direction of the character wheel 2 under the action of the rotation stopping spring 9, the positioning claw 81 of the rotation stopping slide block is continuously clamped in the rotation stopping groove 21 of the character wheel 2, the rotation stopping slide block 8 and the character wheel 2 are in a buckling state, at the moment, the character wheel 2 cannot automatically rotate and reset under the action of magnetic force, and therefore, a new password can be set by manually stirring the character wheel 2.

After a new password is set, the operation part 702 of the sliding block 70 is shifted, so that the limit of the sliding block 70 to the switch 20 is released, the switch 20 is retracted to the initial position under the action of the elastic force, the bush 3 is reset to the initial position under the action of the elastic force along with the retainer 5, the bush 3 is meshed with the character wheel 2 again, and the whole password setting process is completed.

Referring to fig. 24 to 27, in combination with the structural details of the other drawings, the scrambling code status of the present invention:

the character wheel 2 is positioned at a correct unlocking password position, the switch 20 is reversed, the messy code deflector rod 90 moves along with the switch 20, the second guide inclined plane 901 of the messy code deflector rod 90 extrudes the second inclined side surface 8383 of the rotation stop slide block 8, so that the rotation stop slide block 8 is far away from the character wheel 2, the positioning claw 81 is separated from the rotation stop groove 21, the character wheel 2 is automatically reset under the action of magnetic force, the bush 3 and the character wheel 2 synchronously rotate, and the correct alignment relation between the second notch 32 of the bush 3 and the second convex block 41 of the lock shaft 4 is disturbed, so that locking is realized.

Through the scheme, the axial movement of the bushing 3 and the lock shaft 4 is limited under the condition of incorrect passwords through the matching relation between the first lug 122 and the first notch 31 and the matching relation between the second lug 41 and the second notch 32, and only when a user inputs the correct password, the user can drive the lock shaft 4, the bushing 3 and the reset deflector rod 10 to axially move through the toggle switch 20, so that the lock shaft 4 performs unlocking action, the bushing 3 is separated from the character wheel 2 when axially moving, the rotation stop slider 8 is separated from the character wheel 2 when axially moving the reset deflector rod 10, the character wheel 2 rotates under the action of the first magnet 6 and the second magnet 7 to realize password resetting, and the lock product adopting the invention is particularly suitable for public occasions with the requirement of one-time password; because the switch 20 has linkage relation with the lock shaft 4, the retainer 5 and the reset deflector rod 10 at the same time, when a user applies force to the switch 20 by fingers to perform unlocking operation, the switch 20 can be directly pushed to the password resetting position from the unlocking position under the action of force application inertia, password resetting is completed while unlocking, and the operation is simple and convenient, and the lockset is convenient to manage; in addition, the rotation of the character wheel 2 is limited by the rotation stop spring 9 matched with the rotation stop slide block 8, and the block-shaped structure of the rotation stop slide block 8 ensures that the character wheel 2 is not easy to deform and damage when frequently subjected to the reaction force of the character wheel, and the structure and the function are more stable; the invention has various application occasions, and various application occasions requiring temporary passwords are applicable, such as temporary storage cabinets, electronic device locks, locomotive locks and the like.

The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
