Description

Technical Field

[0001] This invention relates to a device for use on locks. Background Technology

[0002] With the continuous development of society, people's use of locks is also gradually increasing, as locks are one of the important methods for people to protect their property. Traditional locks are mainly unlocked with keys, but carrying too many keys has caused inconvenience for travel and use, and there are also problems such as loss and broken keys. Therefore, developing a secure keyless lock that unlocks using a password can alleviate some of the troubles caused by the above problems. Taking some combination locks currently used in the market as examples, there are mechanical and electronic types. This invention focuses on the mechanical type. The commonly used mechanical combination locks are rotary dial type and single-dial type. However, the related technologies for these two types appeared and were used relatively early, and their technological development has stagnated and fallen behind. Taking the single-dial type as an example, it adopts a method of unlocking by directly tapping the unlocking mechanism into the grooves on the side of several combination discs. Therefore, in the process of tentatively unlocking without the unlocking code, a single set of combination discs can be rotated and the unlocking mechanism can be used to repeatedly try to tap into the grooves of that set of combination discs. When the unlocking mechanism hits exactly in alignment with the groove, because there is a gap in the groove, this set of combination discs will produce a certain groove misalignment sound or no sound when tapped, which is obviously different from the sound when the groove is not aligned. Therefore, even without the unlocking code, one can listen or use auxiliary devices such as a handset to deduce the unlocking position of each combination lock groove by taking advantage of the aforementioned differences in sound, thereby breaking the lock. At the same time, existing combination locks also have the disadvantage of insufficient options for unlocking methods. This invention is created to solve any of the above problems. Summary of the Invention

[0003] The present invention aims to address the problem of insufficient available options for unlocking methods or opening schemes of existing combination locks, and to provide a new unlocking method, opening scheme, or unlocking solution. Alternatively, it aims to address the problem that when the unlocking mechanism of an existing combination lock attempts to enter the groove but fails to do so, it produces discrepancies in sound or inconsistent sound. The present invention provides a device for use on locks to solve any of the above problems.

[0004] 1. The technical solution adopted by the present invention to solve its technical problem is: a device for a lock, including at least one rotating part (11), and further including a bracket (1), an opening part (10), a driving part (18), and at least one combination wheel (14), wherein the opening part (10) is disposed on one side of the inner cavity of the bracket (1), the driving part (18) is disposed on the other side of the inner cavity of the bracket (1), the opening part (10) is provided with at least one opening end, and at least one combination wheel (14) is also provided on the inner cavity of the bracket (1), and the combination wheel (14) is provided with at least one opening point. The above describes the parts and installation for solving the problem described in the present invention.

[0005] The operation method to solve any of the above problems is as follows: When the drive unit (18) is turned to one side, the dial on the drive unit (18) will move to one side and press against the end or locking position of the opening part (10), thereby causing the opening part (10) to rotate to one side. When the opening part (10) rotates, it will drive the opening end on it to strike the front end plane of the opening point of the code wheel (14). When the drive unit (18) is turned to push the opening part (10) to one side, assuming that the opening end and the opening point are aligned, the opening end will slide into the opening point, thereby completing the operation process to solve any of the above problems. Since the opening end first strikes the front end plane of the opening point and then moves and slides into the opening point when unlocking, the unlocking sound produced when the opening end strikes the code wheel is consistent regardless of where the opening point is rotated. This effectively solves the problem of the aforementioned unlocking mechanism having a difference in sound or inconsistent sound when directly striking the groove to unlock.

After the rotating part (11) is installed, it is indirectly connected to the combination wheel (14) in a movable manner through the connecting shaft (17), gear (16), and internal gear (105). In this embodiment, there are three sets of rotating parts (11). The rotating parts (11) are marked with 36 English letters or numbers. When the opening point (111) is aligned with the opening end (139), the characters on the rotating part (11) that are aligned with the external markings on the bracket (1) are the unlocking combination characters. In solving the problem described in this invention, the rotating part (11) can be directly connected or welded to the combination wheel (14) without the need for components such as the connecting shaft (17). (See Appendix) Figure 2 , 13 (As shown in Figure 14)

[0042] How to use the device on the lock: Example 1

[0043] 1. Unlocking process.

[0044] The unlocking process of this embodiment of the invention involves first holding the correct unlocking code, then turning each rotating part (11) to drive the corresponding code wheel (14) to rotate. When the correct unlocking code characters are aligned with the markings on the outside of the bracket (1), the opening points (111) on each set of code wheels (14) will move simultaneously and align with each set of opening ends (139) on the opening part (10). After alignment, the outer dial point (132) is turned downwards to cause the drive part (18) to move backwards, or the locking rod (3) is pressed downwards to cause the locking position (145) on it to push the drive part (18) to move backwards. When the drive part (18) moves backwards, the front arc-shaped surface of the dial point (136) on it will press against the end (149) of the opening part (10). 149) When pressed, the opening part (10) will rotate to one end, causing the three sets of opening ends (139) provided thereon to rotate clockwise and strike the front end of the opening point (111) of each password wheel (14) at the front plane contact point (110). When the rear end of the push end (149) of the push point (136) on the drive part (18) is moved backward, the sets of opening ends (139) on the opening part (10) will slide backward on the plane of each password wheel (14). At this time, assuming that the positions of each set of opening points (111) and opening ends (139) are aligned, each opening end (139) will slide down into the opening point (111) of each password wheel (14) under the elastic pressure of the end (149) or the elastic pressure of the front end of the push point (136). After the above operations are completed, since the opening end (139) is no longer blocked by the plane of the password wheel (14), the rotation space of the opening part (10) will increase, so that the two ends of the locking pin (6) at its front end can be rotated to separate from the locking position (142) of the lock beam (4) and the locking position (143) of the lock rod (3) respectively, so as to achieve the purpose of unlocking.

[0045] If it is necessary to maintain the unlocked state, the forward return force of the elastic body (9) located at the rear end of the opening part (10) can be used to push the opening end (139) forward against the inside of the opening point (111) and keep it locked in the opening point (111). The use of the elastic body (9) in this embodiment is only to achieve a better unlocking effect, and therefore it should not be limited to the fact that the present invention can only be implemented with its presence.

[0046] The above-described unlocking design utilizes the opening end on the opening part. When unlocking, it first strikes the flat surface at the front of the opening point of the combination wheel, and then slides into the opening point. This design is mainly to solve the problem of trying to deduce the position of the opening point by repeatedly striking the flat surface of the combination wheel and striking the opening point when there is no unlocking code. This is because when unlocking correctly, the opening end (139) will enter the opening point (111), while when unlocking incorrectly, the opening end (139) will strike the flat surface of the combination wheel (14) and be blocked. Therefore, when only the opening point (111) on a single set of combination wheels (14) is aligned with the opening end (139), if the unlocking method of directly striking the opening point (111) with the opening end (139) is adopted, there will be a problem that when unlocking, the combination wheel (14) that is aligned with the opening point (111) will be empty and silent, while the other two sets that are struck on the plane of the combination wheel (14) will make a sound. This is because there is an opening point gap in the set aligned with the opening point (111). Therefore, by utilizing the above-mentioned sound differences, it is possible to deduce the unlocking position of each set of opening points (111) and thus break the unlocking device.

[0047] 2. Reset process and unlocking complete.

[0048] After the above unlocking process is completed, the front end of the lock bar (3) and the lock beam (4) can be pulled upwards. When the lock bar (3) is pulled upwards, it will pull the drive unit (18) forward together. When the dial point (137) on the drive unit (18) moves forward a certain distance, it will touch one side of the end (149) that has moved backwards during unlocking. The dial point (137) pushes one side of the end (149) to cause the end (149) to rotate in the opposite direction and return to its original position. When the end (149) returns to its original position, it will rotate the opening part (10) in the opposite direction together, causing the opening end (139) on the opening part (10) and the opening point (111) on the code wheel (14) to be pulled out and separated. After the two are separated, the opening part (10) will be returned to its original position under the continued forward push of the dial point (137). At this time, the short end of the lock pin (6) will enter the locking position (144) on the lock bar (3). During the forward movement of the aforementioned drive unit (18), the slots (131) provided on the drive unit (18) will move above the locking whistles (103) of each combination wheel (14), and under the pressure of the front end of the elastic body (8) pressing against the locking position (134) on the front side of the drive unit (18), the slots (131) will enter the locking whistles (103) of each combination wheel (14) to complete the engagement. At the same time, the guide point (133) on the front side of the drive unit (18) will move to the low position of the guide position (119). At this time, the lock beam (4) has been completely pulled out and the lock has been unlocked, and the components are in the standby and reset state. (See Appendix) Figure 11 (As shown)

[0049] 3. Locking process.

[0050] This invention includes a function that automatically resets the scrambled password position when the lock is closed.

[0051] When the front end of the locking bar (3) and the locking beam (4) are pulled out, they can rotate freely. However, when locking, in order to prevent the locking bar (3) from being inserted into the lock at other abnormal angles, the end of the locking beam (4) with the locking slot (142) at the front end of the locking bar (3) must be set to align with the lock hole (113) on the bracket (1) before it can be inserted into the lock. The setting method is as follows: the end of the locking bar (3) is set as a semi-circular shaft (146) structure. When the end of the locking beam (4) with the locking slot (142) is aligned with the lock hole (113), one side of the plane of the semi-circular shaft (146) is also aligned with the edge of the support point (122) at the same time in an unobstructed state. At this time, the semi-circular shaft (146) can be inserted downwards. However, when inserted at other angles, the circular part of the semi-circular shaft (146) will be blocked by the edge of the support point (122) and cannot pass through.

[0052] When one end of the lock beam (4) with the locking position (142) is aligned with the lock hole (113), the lock beam (4) and the locking rod (3) can be pressed down to move downward. When the locking rod (3) moves downward, the shorter end of the locking pin (6) in the locking position (144) will slide upward through the inclined surface of the locking position (144) and enter the locking position (143), while the longer end of the locking pin (6) will enter the locking position (142) on the lock beam (4), thereby completing the locking operation.

[0053] During the process of the locking pin (6) sliding out of the inclined surface of the locking position (144) and entering the locking position (143), each set of opening ends (139) will briefly strike the plane of the combination wheel (14) before returning to its original position. The reason is that when the locking pin (6) slides out of the locking position (144), the opening part (10) will be rotated clockwise by the locking pin (6), thereby causing the opening end (139) to strike the plane of the combination wheel (14). Therefore, it is necessary to set the connection between the opening part (10) and the locking pin (6) as a flexible connection to avoid If the opening part (10) is damaged during this process, an elastic body (5) is added at the connection between the two. When the locking pin (6) rotates the opening part (10), the elastic body (5) provides elastic buffering to prevent the opening end (139) from hitting the plane of the code wheel (14) under overload and thus damaging the opening part (10). When the elastic body (5) is not used for elastic buffering, the inner groove (112) provided on the code wheel (14) can also be used as a buffer for the impact of the opening end (139).

[0054] During the locking process described above, the slots (131) on the drive unit (18) move backward together and move the whistles (103) on each combination wheel (14), causing each combination wheel (14) to rotate to the position of its opening point (111), thereby achieving automatic reversal of the scrambled combination when locking. When the guide point (133) on the drive unit (18) moves backward to the high point of the inclined surface of the guide position (119), the front side of the drive unit (18) is lifted upward, causing the slots (131) on the drive unit (18) to disengage from the whistles (103) and return to their original positions, thus completing the entire locking process. After locking is completed, the plane of the combination wheel (14) blocks the rotation space of the opening end (139), thereby keeping the opening part (10) in the locked state.

[0055] To prevent the opening points (111) on each group of combination wheels (14) from having the same position after being turned back during the locking and turning-back process, the contact time between each group of card slots (131) and the card whistle (103) can be changed by setting the width of each group of card slots (131) differently. That is, the group with narrower card slots (131) will contact the card whistle (103) first and turn back, while the group with wider card slots (131) will contact the card whistle (103) later and turn back, thereby achieving differential turning back to shuffle the position of each group of combination wheels.

[0056] 4. Protection settings and usage process of the device.

[0057] To prevent the possibility of probing the opening point by using the rotating part to turn it, the present invention includes a function to lock the rotation of the rotating part when unlocking, and a function to prevent the rotating part from spinning freely after locking the rotating part and forcibly turning it, which would damage the device.

[0058] To prevent the possibility of using the rotating part (11) to probe the opening point (111) on the combination wheel (14) during the unlocking process, the combination wheel (14) needs to be locked during the unlocking process to prevent it from rotating. The locking method is as follows: using the teeth (130) provided on the drive part (18), during unlocking, the teeth (130) will move backward and press against the gear (16) on the combination wheel (14) and mesh with the gear (16) to fix it, thereby causing the combination wheel (14) to lock and prevent it from rotating. To prevent damage to the device caused by forcibly moving the rotating part (11) and disrupting the meshing, a soft connection between the rotating part (11) and the code wheel (14) is used. In this embodiment, the connection between the rotating part (11) and the code wheel (14) is indirectly achieved through the connection between the gear (16) and the connecting shaft (17). This is achieved by providing a groove (106) on the gear (16) and a protrusion (107) at the end of the connecting shaft (17), and by using a large spring (12) to press the rotating part (11) into shape. When the gear (16) is connected to the protrusion (107) at the end of the connecting shaft (17) under the pulling force of the paired connecting shaft (17), the protrusion (107) will be pressed into the groove (106) of the gear (16) to form a movable connection. During use, when the rotational force of the rotating part (11) is greater than the set connection force between the protrusion (107) and the groove (106), the protrusion (107) will slide out of the groove (106), thereby causing the connection between the connecting shaft (17) on the rotating part (11) and the gear (16) to form a separated free-spinning state, avoiding the transmission of overload torque to the gear (16). When free-spinning occurs, the protrusion (107) can be put back into the groove (106) simply by rotating the rotating part (11) again while the combination wheel (14) is locked.

[0059] 5. How to use and modify the device's password.

[0060] The embodiments of the present invention include the function of freely changing the password in a partially unlocked state.

[0061] When unlocking, the password is used by aligning the characters on the rotating part (11) with the unlocking mark on the front of the bracket (1) to identify and control the opening point (111) on the password wheel (14) to move to the correct unlocking position. Unlocking is only possible when the unlocking positions of all three sets of password wheels (14) are consistent and correct. During use, the position of the password characters can be modified. The modification process is as follows: when the drive part (18) is in the half-unlocked state (middle position), and each opening end (139) is still within the opening point (111) of the corresponding password wheel (14), press down on the rotating part (11) to cause the gear (16) connected to the rotating part (11) to push outwards and separate from the internal teeth (105) on the password wheel (14), or the gear (16) is pushed outwards and separated by the elastic force of the small spring (15). In the separated state, the rotating part (11) can be turned. The gear (16) is driven to change its connection angle with the inner teeth (105) of the code wheel (14). After the change is completed, the rotating part (11) is released upward. At this time, under the pulling force of the large spring (12) pressing the rotating part (11), the gear (16) and the inner teeth (105) will be re-engaged and fixed. Since the connection angle between the rotating part (11) and the code wheel (14) after re-fixation has changed, the characters on the rotating part (11) that are aligned with the unlocking mark on the bracket (1) also change at the same time, thereby generating new unlocking code corresponding characters, achieving the purpose of changing the code. Because the stop (129) on the drive unit (18) prevents the gear (16) from moving outward when the lock is engaged, the password cannot be changed when the lock is engaged. To prevent accidental password changes when the lock is fully engaged, a stop (152) is provided on the drive unit (18) to prevent the gear (16) from moving outward. Therefore, password changes can only be made when the lock is partially engaged, and not when the lock is engaged or fully engaged. However, when the stop (152) is removed, password changes are allowed when the lock is fully engaged. The return force of the large spring (12) should be greater than that of the small spring (15). (See Appendix) Figure 4 , 11 (As shown in Figure 14)

[0062] Example 2: Other unlocking drive methods and usage methods for devices used on locks.

[0063] In the following embodiments, the external toggle point (132) is not required, and its toggle function can be replaced by the locking lever (3). This embodiment: (See Appendix) Figure 3 , 7 (As shown in Figure 17)

[0064] 1. This embodiment of the invention also allows for the use of a baffle (120) on the bracket (1) for new unlocking and locking methods. The front end of the toggle point (136) on the drive part (18) is not required to be an arc structure and can be modified to a straight structure. The new setting and usage method is as follows: First, a new elastic body (19) is set at the rear end of the opening part (10). The elastic body (19) is an elastic element with both elastic force and torque. The extended part of the front end of the elastic body (19) is engaged at the bottom of one side of the opening part (10), and the protruding part of its rear end is installed on one side of the support point (122). When in use, the torque of the elastic body (19) is set to the clockwise direction, so that the opening part (10) is turned to the unlocking direction by using the torque. Then, the end (149) on the opening part (10) is set on one side of the baffle (120), so that the opening part (10) is returned to the locked state. When unlocking, as the drive unit (18) moves backward, the dial (136) on it pushes the end (149) to cause the opening unit (10) to move backward as well. After the end (149) moves backward a certain distance, it separates from the stop plate (120), thereby canceling the rotation limit restriction on the opening unit (10). At this time, under the steering torque of the elastic body (19), the opening end (139) on the opening unit (10) will be rotated clockwise and strike the flat contact point (110) of each combination wheel (14). When the dial (136) on the drive unit (18) is continuously turned to push the end (149) backward, the opening end (139) on the opening part (10) will slide backward on the plane of each combination wheel (14). Assuming that the positions of each set of opening points (111) on the combination wheel (14) and the opening end (139) are aligned, under the steering torque of the elastic body (19), the opening end (139) will slide into the opening point (111) of each combination wheel (14), thereby completing the new unlocking process. In this embodiment, the end (149) can be set to be rigid. When the inner groove (112) on the combination wheel is used as a buffer for the opening end (139) during locking, the baffle (120) can be set to be elastic to buffer the reverse rotation of the end (149) on the opening part (10).

[0065] 2. During the reset process, when the dial (137) on the drive unit (18) moves forward a certain distance, it will touch one side of the end (149) that has been moved backward during unlocking. The dial (137) pushes one side of the end (149) to cause the end (149) to rotate in the opposite direction and return to its original position. When the end (149) returns to its original position, it will rotate the opening unit (10) in the opposite direction, causing the opening end (139) on the opening unit (10) and the opening point (111) on the password wheel (14) to be pulled out and separated. After the two are separated, under the forward return thrust of the elastic body (19) or the forward push force of the dial (137), the end (149) on the opening unit (10) will be placed back on one side of the baffle (120), thereby causing the opening unit (10) to return to its original position and remain in the locked position.

[0066] Example 3: Other unlocking drive methods and usage methods for devices used on locks.

[0067] 1. The present invention also allows the use of the locking position (148) on the opening part (10) and the shift fork (135) on the driving part (18) in a new unlocking driving method to drive the opening part (10) to unlock, without the need for the use of the shift point (136), the end (149), the baffle (120), and the elastic body (19). The limiting function of the baffle (120) allows the opening end (139) to be blocked on the plane of the combination wheel (14) to achieve the limiting. The function of the end (149) is replaced by the locking position (148), and the function of the shift point (136) is replaced by the shift fork (135). The new setting and usage method is as follows: When unlocking, when the drive unit (18) moves backward, the dial point (153) set on one side of the dial fork (135) will press against one end of the locking position (148), and the dial fork (135) will move the locking position (148) to cause the opening unit (10) to move backward together. At this time, the opening end (139) will also slide backward on the plane of the password wheel (14). Assuming that the opening end (139) and the opening point (111) are aligned, the opening end (139) will enter the opening point (111) under the elastic pressure of the dial point (153) or the locking position (148) to complete the unlocking process. When the combination wheel (14) and the opening end (139) are made of materials with adsorption properties, such as magnetic steel or magnetic plastic, the dial point (153) can be omitted as a driving component. The opening end (139) can be magnetically attracted into the opening point (111) to complete the unlocking. Therefore, it is not necessary to have a dial point (136), an end (149), a baffle (120), and an elastomer (19) to implement this invention. At the same time, the configuration of each embodiment shows that there are multiple ways to drive the opening end into the opening point. (See Appendix) Figure 4 (As shown)

[0068] 2. During the reset process, the dial point (154) provided on the other side of the dial fork (135) on the drive unit (18) presses against the bottom of the locking position (147) that has shifted downwards during unlocking when the dial point (154) moves forward, and pushes the locking position (147) upwards to return to its original position, thereby causing the opening unit (10) to rotate in the opposite direction to return to its original position.

[0069] For the same operational procedures not described in detail in Examples 2 and 3 above, please refer to the description in Example 1.

[0070] Several other embodiments:

[0071] 1. When the present invention uses a forward direct knocking unlocking scheme, the opening end (139) and the opening point (111) are allowed to be set at the same parallel angle position. When unlocking, the opening end (139) does not need to slide backward. When the control unit (18) moves the opening part (10) to unlock, the opening end (139) can directly enter the opening point (111) to complete the unlocking, thereby realizing a simpler unlocking method.

[0072] 2. In this embodiment of the invention, when the gear (16) is not used, a tooth (108) can be fixedly connected to the front top of the password wheel (14) to replace the gear (16) as a component for modifying the password. The method of use is as follows: When in use, the teeth (100) provided in the concave hole (102) of the rotating part (11) are engaged with the teeth (108) at the front top of the password wheel (14). When changing the password, the rotating part (11) is pressed down to cause the teeth (100) in its concave hole (102) to move down together and separate from the teeth (108). After the teeth (100) and teeth (108) are separated, the connection angle of the rotating part (11) can be freely rotated to change. After the change is completed, the rotating part (11) is pulled up to return and cause the teeth (100) and teeth (108) to re-engage. Since the connection angle between the rotating part (11) and the password wheel (14) has changed after reconnection, the characters on the rotating part (11) that are aligned with the unlocking mark of the bracket (1) also change at the same time, thereby generating new unlocking password corresponding characters and achieving the purpose of changing the password. In this embodiment, the teeth (108) are allowed to be integrated with the code wheel (14) for integrated production. (See Appendix) Figure 2 , 19 (As shown)

[0073] Meanwhile, when the connecting shaft (17) is not used, the teeth (100) and teeth (108) can be directly and rigidly fixed together, thereby causing the rotating part (11) to be fixedly connected to the code wheel (14). Alternatively, without the teeth (100) and teeth (108), the rotating part (11) and the code wheel (14) can be directly welded together. Therefore, it is not necessary to have the connecting shaft (17) to solve the problem described in this invention.

[0074] 3. This embodiment of the invention also allows the use of any one or a combination of teeth (138) and slots (131) for a reverse-spinning method when scrambling the code during locking, thereby further enhancing the differential reverse-spinning of the positions of each set of code wheels. The method of using the mixed reverse-spinning method is as follows: During the unlocking process, the teeth (138) and slots (131) move forward together with the drive unit (18). When the slots (131) move to the position aligned with the card whistle (103), at this time, under the pressure of the front end of the elastic body (8), at least one set of slots (131) will slide into the card whistle (103), and at the same time, the teeth (138) will move downward together and enter the front end of the gear (16) parallel to the position of the gear (16). When locking, the teeth (138) move backward and push the gear (16) to rotate, causing the combination wheel (14) to rotate and change its angular position. Simultaneously, the slot (131) moves backward and moves the whistle (103) on the combination wheel (14). When the guide point (133) moves backward to the high point of the guide position (119), the teeth (138) and slot (131) are raised and separated from the gear (16) and whistle (103), thus completing the above-mentioned reverse-scrambling operation. Furthermore, this embodiment of the invention can also change the number of teeth on each set of teeth (138) to alter the reverse-scrambling stroke when the gear (16) is turned, thereby achieving more differentiated reverse-scrambling functions. (See Appendix) Figure 23 (As shown)

[0075] 4. This embodiment of the invention can be applied in the fields of luggage and cabinet locks by providing a through hole at the rear end of the bracket (1) and connecting an extension rod (150) and an accessory for adding a door lock at the end of the locking rod (3). (See appendix) Figure 20 , 21 (As shown in Figure 22)

[0076] 5. In this embodiment of the invention, without modifying the original design principle, the number of combination wheel assemblies can be increased by increasing the length of the bracket (1), thereby increasing the number of combinations of unlocking password numbers and further improving the security of the device. For example, the number of combination wheel assemblies can be increased from three to four or more, or the number of combination wheel assemblies can be reduced to one or two (see Appendix). Figure 18 (As shown).
