DETAILED DESCRIPTION

[0040] Hereinafter, some working principles of conventional wheel locks are first explained to facilitate a clearer understanding of the technical solution of the present utility model.

[0041] (1) Infrastructure

[0042] See also Figure 2-4 The outer shell of the word wheel lock is generally provided with a fixing seat 2 for fixing the password component 1. The password component 1 is composed of a retaining frame 11 that is slidably fitted on the fixing seat 2, a lock shaft 12 that is passed through the retaining frame 11, a plurality of bushings 13 that are sleeved on the lock shaft 12, and a word wheel 14 that is sleeved on each bushing 13; wherein, the retaining frame 11 is used to limit the axial position of the word wheel 14 on the lock shaft 12, so that the word wheel 14 and its corresponding bushing 13 keep rotating synchronously when the lock is on or off, and in the code changing state (mainly referring to the state in the industry where the lock can be changed), the word wheel 14 and the bushing 13 are in a state of rotation. The sleeve 13 disengages to allow the character wheel 14 to rotate relative to the sleeve 13, thereby achieving the purpose of changing the password. Therefore, the movement of the retainer 11 determines whether the lock switches to the code-changing state. When the locking protrusion 121 on the lock shaft 12 is aligned with the clearance groove 131 in the sleeve 13 (i.e., the user enters the correct password / the panel 4 displays the number corresponding to the correct password), the locking protrusion 121 can be inserted into the clearance groove 131 to achieve axial movement of the lock shaft 12 within the fixed seat 2. At this time, the user will not be interfered with when rotating the knob 3 or handle of the lock, and the lock can be unlocked normally. In addition, the retainer 11 and the lock shaft 12 are reset by the retainer spring 15 and the lock shaft spring 16 respectively.

[0043] (2) How to reset to zero

[0044] See also Figure 4 、 5The lock shaft 12 and the character wheel 14 are each equipped with a corresponding first magnet 17 and second magnet 18. When the character wheel 14 is not subject to any forces from other components, the magnetic attraction between the first magnet 17 and the second magnet 18 causes the character wheel 14 to rotate without the user having to manipulate the character wheel. This rotation ceases when the magnetic forces reach equilibrium. In typical lock designs, when the magnetic forces reach equilibrium, all character wheels 14 display the number "0" on the outside of the panel 4 (0 is a common setting in the industry). This function is therefore commonly referred to as "reset to zero."

[0045] (3) Stopping the character wheel

[0046] See also Figure 6 、 7 A rotation-stop slide 6 driven by a rotation-stop spring 5 is provided in the fixing seat 2; the rotation-stop slide 6 is provided with a rotation-stop buckle 61 corresponding to the number of the character wheels 14. In the normal state, the elastic force of the rotation-stop spring 5 causes the rotation-stop slide 6 to move toward the character wheel 14, so that the rotation-stop buckle 61 is embedded in the rotation-stop groove 141 on the circumference of the character wheel 14, so that after the user turns the character wheel 14, when the character wheel 14 is no longer subjected to external force, it can stay and will not rotate due to the action of the magnetic force. It can be understood that the force of the user turning the character wheel 14 is greater than the elastic force of the rotation-stop buckle 61, and the magnetic force is smaller than the elastic force of the rotation-stop buckle 61.

[0047] (4) How to switch to zero state

[0048] First, the definition of zero state is the state when the lock wheel is automatically reset to a preset set of numbers (such as 0000) when it is not turned by the user. Figure 2 、 6 When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. When the lock is unlocked, the return-to-zero lever 7 is in contact with the locking lever 7 and the locking lever 7 is in contact with the locking lever 7. That is to say, by rotating the operating component to a certain angle, the lock can be switched to the zero state.

[0049] The above are all technical means that have been disclosed in the prior art and are not the focus of the improvement of the present invention. The main improvement of the present invention lies in the related structure between the operating component of the word wheel lock and the zeroing lever. Therefore, the specific structure of the password component is not limited. That is, in actual application, the present invention can also be applied to word wheel locks that realize the word wheel zeroing function by non-magnetic attraction.

[0050] On this basis, reference Figure 1-20 As shown, the utility model discloses a character wheel zeroing mechanism, comprising a fixing seat 2 and an operating assembly installed in parallel in a character wheel lock housing 100;

[0051] A reset lever 7 for switching the zero state of the character wheel lock is movably mounted in the fixing base 2. When the reset lever 7 moves axially relative to the fixing base 2, the character wheel lock enters the zero state. When the reset lever 7 is reset, the character wheel lock exits the zero state. In the zero state, the character wheel 14 of the character wheel lock rotates to reset itself.

[0052] A first stopper 9 and a first spring 10 are provided between the operating assembly and the return-to-zero lever 7. The first stopper 9 slides in the fixing seat 2 in a direction perpendicular to the axis of the return-to-zero lever 7. The first spring 10 is provided between the first stopper 9 and the fixing seat 2 or the wheel lock housing 100.

[0053] The operating assembly is provided with a return-to-zero boss 81 and a linkage boss 82 on its circumference. The return-to-zero boss 81 is disposed opposite to the end of the return-to-zero lever 7. When the return-to-zero boss 81 abuts the return-to-zero lever 7, the return-to-zero lever 7 is driven to move axially so that the character wheel lock enters the return-to-zero state. The linkage boss 82 is disposed opposite to the first stopper 9. When the linkage boss 82 abuts the first stopper 9, the first stopper 9 is driven to compress the first spring 10.

[0054] A limiting protrusion 71 is provided on the side surface of the end of the return-to-zero lever 7, and the first stopper 9 is provided with a limiting stopper 91 opposite to the limiting protrusion 71. The limiting protrusion 71 and the limiting stopper 91 limit each other: see Figure 10 In the locked state, the limiting protrusion 71 limits the limiting block 91 so that the first block 9 remains in the state of compressing the first spring 10; see Figure 11 In the unlocked state, the limit block 91 limits the limit protrusion 71 to prevent the zeroing lever 7 from resetting, and the word wheel lock remains in the zeroing state.

[0055] Through the above scheme, the utility model sets the first stopper 9 and the first spring 10 between the operating assembly of the word wheel lock and the zero return lever 7, and limits each other through the limiting protrusion 71 of the zero return lever 7 and the limiting stopper 91 of the first stopper 9. Especially in the unlocked state, when the zero return boss 81 pushes the zero return lever 7 to move axially and releases the limiting protrusion 71 on the limiting stopper 91, the limiting stopper 91 can bounce up under the action of the first spring 10 so that the limiting stopper 91 blocks the limiting protrusion 71 to realize the limiting stopper 91 on the limiting The limiting block 71 is used to prevent the reset lever 7 from being reset. At this time, the character wheel lock can be kept in the reset state, so that the character wheels 14 of the character wheel lock have a long enough time to perform the "character wheel reset" function, ensuring that all the character wheels 14 of the character wheel lock can be reset to zero, eliminating the hidden danger of password leakage; and in the locking process, the linkage boss 82 of the operating component can be linked to the first stopper 9 to restore it to the state of compressing the first spring 10, that is, the limiting block 91 releases the limiting block 71, the reset lever 7 can be reset, and the character wheel lock exits the reset state.

[0056] The following shows a specific implementation of the above-mentioned character wheel zero-reset mechanism.

[0057] The above-mentioned operating component is the lock core tail 8 of the word wheel lock, and the lock core tail 8 is linked with the knob 3 of the word wheel lock to achieve synchronous rotation.

[0058] The above-mentioned zero return boss 81 and linkage boss 82 are staggered in the circumferential direction of the operating component, that is, the angles between the two are different, so that the contact time of the two pairs of structures, the zero return boss 81 and the zero return lever 7, and the linkage boss 82 and the first stop block 9, are different, thereby avoiding mutual interference between the functions.

[0059] See also Figure 20 The fixing seat 2 is provided with a guide groove 21 for sliding engagement with the first stopper 9 , which is used to install the first stopper 9 and guide the sliding direction of the first stopper 9 .

[0060] A linkage inclined surface 821 is provided below the side surface of the linkage boss 82, and a protrusion 92 is provided on the side of the first stopper 9 facing the operating component. The linkage inclined surface 821 and the protrusion 92 are movably matched to realize the linkage between the linkage boss 82 and the first stopper 9. When the operating component rotates and the protrusion 92 contacts the linkage inclined surface 821, the linkage inclined surface 821 presses the protrusion 92 downward to cause the first stopper 9 to compress the first spring 10.

[0061] See also Figure 2 、 1213. The upper surface of the fixing base 2 is covered with a panel 4, which is provided with a movable hole 41. A button 20 is movably fitted in the movable hole 41. The button 20 is arranged opposite to the first stopper 9, and the button 20 and the first spring 10 are located on the upper and lower sides of the first stopper 9, for driving the first stopper 9 to compress the first spring 10. Figure 13 By actively pressing the button 20, the user can actively release the limit of the first block 9 on the zeroing lever 7, thereby allowing the character wheel lock to quickly exit the zeroing state.

[0062] Furthermore, the button 20 is hooked on the inner wall edge of the movable hole 41 by a plurality of hooks 201 to prevent the button 20 from being separated from the panel 4 .

[0063] At the same time, a driving block 30 is provided between the above-mentioned button 20 and the first stop block 9. The driving block 30 can be designed into different shapes according to the installation positions of the button 20 and the first stop block 9 in the panel 4 and the fixing seat 2, mainly to achieve the linkage between the two; a reset spring 40 is provided between the driving block 9 and the fixing seat 2, which is used to drive the driving block 9 and link the button 20 for reset.

[0064] As described above, the wheel lock has a "wheel reset" function and can maintain the wheel lock in the reset state for a long time during the unlocking process. In addition, when some applications require more functional features for the wheel lock product, such as the wheel lock used in public lockers, each password set by the user is a one-time use. Therefore, the merchant hopes that the lock can automatically "reset the password" after unlocking. That is, the lock can automatically change the password to the preset password to achieve the initialization of the lock without the user's operation. To this end, based on the above technical solution, the present invention can also be improved to enable the wheel lock to have a temporary mode, that is, each password set is a one-time use and automatically resets to the initial password after unlocking.

[0065] See also Figure 14-19 The word wheel lock with a temporary mode also includes a retaining frame 11, a second stopper 50 and a second spring 60; the circumferential surface of the operating assembly is provided with a code-changing groove 83 for the end of the retaining frame 11 to movably cooperate with; the second stopper 50 is arranged in the code-changing groove 83 to block the movement of the end of the retaining frame 11, and the second spring 60 is located between the second stopper 50 and the side wall of the code-changing groove 83; a compression inclined surface 501 is provided on one side of the second stopper 50, so that when the end of the retaining frame 11 contacts the second stopper 50 on this side, it can push the second stopper 50 to compress the second spring 60, so that when the operating assembly rotates, the retaining frame 11 will not be blocked by the second stopper 50 to avoid interfering with the rotation of the operating assembly; in the circumferential direction of the operating assembly, the two ends of the zeroing boss 81 are respectively located on the inner sides of the two ends of the code-changing groove 83.

[0066] The unlocking principle of temporary mode is:

[0067] ① When the operating assembly rotates in the unlocking direction, the end of the retainer 11 first enters the code change groove 83 to make the word wheel lock enter the code change state (see Figure 16 );

[0068] ② The operating assembly continues to rotate, and the zeroing lever 7 contacts the zeroing boss 81 to put the character wheel lock into the zeroing state (see Figure 17 ), the superposition of the code change state and the reset state makes the password of the wheel lock automatically reset to the preset password (generally called the initial password), completing the password initialization;

[0069] ③ The operating assembly continues to rotate, and the end of the retaining frame 11 squeezes the second stopper 50 to compress the second spring 60 until the lock is unlocked. If the user needs to change the password, the operation can be performed at this time (if not, the lock will maintain the preset password): the user presses the button 20 on the panel 4, and the button 20 pushes the driving block 30 to act on the first stopper 9. The first stopper 9 compresses the first spring 10 to release the limit on the zero return lever 7. The zero return lever 7 is ejected, and the anti-rotation buckle 61 falls into the anti-rotation groove 141 of the character wheel 14. The character wheel 14 no longer rotates, and the user can change the password by turning the character wheel 14.

[0070] The locking principle of temporary mode is as follows (this explanation is mainly based on the premise that the user has changed the lock password after resetting the password):

[0071] When the operating assembly rotates in the locking direction, the end of the retainer 11 first passes the climbing slope 502 of the second stopper 50 on the return stroke; when the end of the retainer 11 abuts the curved surface 503 of the second stopper 50, the number displayed on the outside of the panel 4 is still the password set by the user; when the retainer 11 climbs to the curved surface 503, the zero return boss 81 contacts the zero return lever 7 again (see Figure 19 ), the wheel lock begins to return to zero again, and the anti-rotation buckle 61 disengages from the anti-rotation groove 141 of the wheel 14. As the operating assembly rotates, when the reset lever 7 completely passes the reset boss inclined surface 811, the wheel lock completes the reset, effectively returning the wheel to zero after the user changes the password. Because the number displayed on the wheel lock after zeroing differs from the password changed by the user, the clearance groove 131 of the bushing 13 and the locking protrusion 121 of the lock shaft 12 are misaligned, preventing the wheel lock retainer 11 from falling into the code change groove 83, effectively preventing the wheel lock from entering the code change state.

[0072] Of course, if the user does not change the password after resetting the password, the above locking principle still holds true, except that the character wheel 14 will no longer rotate because it is already in a state of magnetic balance.

[0073] In the temporary mode, a climbing slope 502 is provided on the other side of the second stopper 50 for pushing the retaining frame 11 to reset, so that the code wheel lock exits the code changing state.

[0074] In the temporary mode, a sliding groove 831 is provided in the code switching groove 83 for the second stopper 50 to slide with.

[0075] The above temporary mode can be used in the following scenarios:

[0076] (1) After the previous user unlocks the lock, the lock automatically resets the password to the initial password, and the user uses the initial password to unlock the lock;

[0077] (2) The cabinet door is open. If the current user needs to use the cabinet, he can change the password to a new one by pressing button 20 and then close the door. If the user does not change the password, the password will remain the initial password when the door is closed.

[0078] (3) Afterwards, the user needs to use the correct password to unlock the door and reset the password again; if the user changes the password by mistake and closes the door (that is, the user does not know what password he changed) or forgets the password, the administrator key can be used to unlock the door or find the code.

[0079] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
