Description

Technical Field

[0001] This invention relates to a lock, and more particularly to a push-button digital lock. Background Technology

[0002] Digital locks, also known as combination locks, are a common type of lock that uses a combination of mechanisms to unlock the door when the user enters the correct password. Digital locks can be divided into two types: those that allow users to change the password and those that do not. Since digital locks with unchangeable passwords are difficult to use once cracked or the password is forgotten, users generally prefer those that allow password changes. However, even digital locks with changeable passwords still have some inconveniences. For example, users can only change the password if it is correct; therefore, if a user has forgotten the original password, they will need to expend considerable effort to crack it before they can change it. To address this, some combination locks are designed with mechanisms that allow users to reset the factory default password. However, to prevent this function from becoming a channel for thieves to crack digital locks, the password reset mechanism usually utilizes the characteristics of the lock itself. For example, cabinet locks often hide the password reset mechanism's interface inside the cabinet or between the lock and the cabinet, making it impossible for malicious individuals to easily crack the password reset mechanism.

[0003] However, this design also causes inconvenience for users. When users want to change the password, they must first open the cabinet door and change the password from the back of the door panel, which is quite troublesome! If the user forgets the password, they will not be able to open it at all. If they still want to use the cabinet, they will have to damage the cabinet door and repurchase the lock and install the cabinet door.

[0004] Therefore, it is clear that a new digital lock, especially a digital lock with a new password reset function, is necessary. Summary of the Invention

[0005] The main objective of this invention is to provide a digital lock, particularly a push-button digital lock, which not only allows the password to be changed on the front, but also allows the unlocking password to be reset using a reset device.

[0006] To achieve the aforementioned objectives, the present invention proposes a push-button digital lock having a reset state, the push-button digital lock comprising:

[0007] A housing having a first direction and a second direction that are not parallel to each other, wherein one side of the housing in the first direction is an operating surface, and the housing has:

[0008] A receiving cavity formed inside the outer shell; and

[0009] A lock groove, the recess of which forms the operating surface of the housing, the lock groove being in communication with the receiving cavity;

[0010] A lock cylinder assembly disposed in the lock cylinder slot, comprising:

[0011] A locking unit, which is disposed in the lock cylinder groove and protrudes from the operating surface; and

[0012] A reset unit is disposed within the unlocking unit and is rotatable relative to the unlocking unit to a reset position;

[0013] A keypad assembly disposed in the receiving cavity, the keypad assembly comprising:

[0014] Multiple button groups are disposed in the receiving cavity, and each button group has:

[0015] A body that penetrates and protrudes from the operating surface, the body being movable along the first direction; and

[0016] A guide sleeve is fitted onto the body, the guide sleeve is movable relative to the body along the first direction, and can be selectively located at a first position or a second position relative to the body;

[0017] A locking actuator is connected to the unlocking unit, and the button group passes through the locking actuator. The locking actuator can move along the second direction to engage the guide sleeve.

[0018] A fixed drive piece, through which the button assembly passes, the fixed drive piece being movable along the second direction to engage the body; and

[0019] A reset actuator, sleeved on the key assembly, is movable along the second direction, thereby pushing one or more guide sleeves located at the second position to the first position; and

[0020] A lock cylinder is disposed through the outer casing and connected to the unlocking unit;

[0021] When the key-type digital lock is in the reset state, the reset unit is located in the reset position, the fixed drive piece is engaged with the body, and the reset drive piece pushes against the guide sleeve, thereby placing each guide sleeve in the first position.

[0022] Therefore, the advantage of this invention is that by connecting the reset device to the reset unit, the invention can be put into a reset state. Thus, when a user wants to reset the password of this invention, it is not necessary to completely disassemble the invention, remove it from locked objects such as cabinets or drawers, or damage the locked objects to reset the password; the user can easily reset the password. Furthermore, since the password of this invention can be reset, the user does not need to worry about forgetting the password.

[0133] Please refer to the following first. Figure 1 , Figure 13 ,and Figure 18 The present invention proposes a button-type digital lock, which has a locked state, an unlocked state, and a reset state.

[0134] The push-button digital lock proposed in this invention includes a housing 1, a lock cylinder assembly 2, a combination dial assembly 4, a lock head 5, and a reset device 6.

[0135] Please refer to Figures 1 to 4The outer casing 1 has a first direction D1 and a second direction D2 that are not parallel to each other. An outer surface of the outer casing 1 in the first direction D1 is an operating surface 11. The outer casing 1 has a receiving cavity 12 and a locking groove 13, wherein the receiving cavity 12 is formed inside the outer casing 1, and the locking groove 13 is recessed to form the operating surface 11 of the outer casing 1. The receiving cavity 12 and the locking groove 13 are arranged along the second direction D2 and are in communication with each other. Specifically, the receiving cavity 12 and the locking groove 13 are located at opposite ends of the outer casing 1 in the second direction D2, and a partition 14 is located between the receiving cavity 12 and the locking groove 13. The partition 14 has a connecting slit 15 along the first direction D1, thereby allowing the spaces of the receiving cavity 12 and the locking groove 13 to communicate with each other. Please refer to the following: Figure 6 In this embodiment, the lock core groove 13 is a cylindrical space, and a positioning groove 131 is formed by the inner circumferential surface of the lock core groove 13. The positioning groove 131 extends along the first direction D1, but is not limited thereto.

[0136] Please refer to the following: Figures 2 to 5 The lock cylinder assembly 2 is disposed in the lock cylinder groove 13 and protrudes from the operating surface 11. In this embodiment, the lock cylinder assembly 2 includes an unlocking unit 20 and a reset unit 30. The unlocking unit 20 is disposed in the lock cylinder groove 13 and protrudes from the operating surface 11. In this embodiment, the unlocking unit 20 has an annular wall portion 21, a handle portion 22, two pads 23, and a positioning device 24.

[0137] Please refer to Figures 3 to 8 The annular wall portion 21 is cylindrical and forms an inner groove 211 around it. The annular wall portion 21 is located within the lock core groove 13 and can rotate relative to the outer casing 1. The annular wall portion 21 has through holes 212 on both sides, a groove 213 on one side, and a placement groove 214 on one side. The through holes 212 on both sides are formed radially through the annular wall portion 21 and are interconnected with the inner groove 211.

[0138] A side groove 213 is recessed into the outer peripheral surface of the annular wall portion 21. In this embodiment, the side groove 213 has two inclined bottom surfaces forming a wedge-shaped groove. Specifically, one end of each of the two bottom surfaces of the side groove 213 is connected to the other end, while the other end of each bottom surface is connected to the outer peripheral surface of the annular wall portion 21, thereby the two bottom surfaces are inclined from the outer peripheral surface of the annular wall portion 21 to the inner side of the annular wall portion 21. In this embodiment, the two side holes 212 and the side groove 213 are arranged along the first direction D1, so that when the invention is in the locked state, the openings of the two side holes 212 and the side groove 213 all face the connecting seam 15. Furthermore, in this embodiment, the side groove 213 is located between the two side holes 212, and the side groove 213 communicates with one of the side holes 212.

[0139] Please refer to Figure 6 and Figure 8The side groove 214 is formed radially recessed on the outer peripheral surface of the ring wall portion 21. When the present invention is in the locked state, the opening of the side groove 214 faces the positioning groove 131 on the inner peripheral surface of the lock core groove 13.

[0140] Please refer to Figures 3 to 8 One end of the handle portion 22 is fixed to the ring wall portion 21, and the other end protrudes from the operating surface 11. The user can rotate the handle portion 22, thereby further rotating the ring wall portion 21 relative to the lock cylinder groove 13. The handle portion 22 has an outer setting groove 221, which is formed through the handle portion 22 along the first direction D1. The outer setting groove 221 communicates with the inner setting groove 211, and the outer setting groove 221 forms a lock hole 222 at the end of the handle portion 22 away from the ring wall portion 21. In this embodiment, the handle portion 22 and the ring wall portion 21 are integrally formed, but the present invention is not limited thereto.

[0141] Two pads 23 are movably disposed in the side through holes 212. Specifically, the two pads 23 can move radially along the annular wall portion 21 in the side through holes 212 and can move inward into the inner setting groove 211. In this embodiment, the opposite ends of each pad 23 in the radial direction of the annular wall portion 21 are an inner end 231 and an outer end 232, respectively. The inner end 231 is in the form of a pointed tip, which can abut against the outer peripheral surface of the reset unit 30; while the outer end 232 is a flat end, and when the inner end 231 abuts against the outer peripheral surface of the reset unit 30, the end face of the outer end 232 is flush with the outer peripheral surface of the annular wall portion 21.

[0142] A positioning device 24 is disposed in the side groove 214. In this embodiment, the positioning device 24 has a compression spring 241 and a bead 242. One end of the compression spring 241 is connected to the bottom surface of the side groove 214, and the other end is connected to the bead 242. The rebound force stored in the compression spring 241 pushes the bead 242 radially outward toward the annular wall portion 21. When the invention is in the locked state, the opening of the side groove 214 faces the positioning groove 131 on the inner circumferential surface of the lock core groove 13, thereby pushing the bead 242 into the positioning groove 131 by the compression spring 241. When the annular wall portion 21 rotates relative to the lock core groove 13, the bead 242 is pressed into the side groove 214. The positioning device 24 and the positioning groove 131 can assist in positioning the rotation angle of the unlocking unit 20, but this is not a limitation, and the positioning device 24 and the positioning groove 131 may not be present.

[0143] Please refer to the following: Figure 2 and Figures 5 to 8The reset unit 30 is disposed within the unlocking unit 20, and the reset unit 30 can rotate relative to the unlocking unit 20 to a reset position. The reset unit 30 has a driven member assembly 301 and a connecting member assembly 302. The driven member assembly 301 is disposed in the inner groove 211, and the driven member assembly 301 includes an inner rotating cylinder 31 and a rotating shaft 32.

[0144] The inner rotating cylinder 31 is located in the inner groove 211 and can rotate relative to the inner groove 211. The inner ends 231 of the two pads 23 abut against the outer peripheral surface of the inner rotating cylinder 31. A longitudinal groove 311 is recessed into the outer peripheral surface of the inner rotating cylinder 31 and extends along the axial direction of the inner rotating cylinder 31. When the reset unit 30 is in the reset position, the longitudinal groove 311 is interconnected with the two side through holes 212, and the two pads 23 are located in the longitudinal groove 311. Specifically, when the reset unit 30 is in the reset position, the inner rotating cylinder 31 rotates relative to the annular wall portion 21 until the longitudinal groove 311 aligns with the two side through holes 212, and the two pads 23 are pushed into the longitudinal groove 311 by the password disk assembly 4. In this embodiment, the longitudinal groove 311 is similar in form to the side groove 213 of the annular wall portion 21. It has two interconnected and inclined bottom surfaces, so that when the inner rotating cylinder 31 rotates, the inner ends 231 of the two pads 23 can slide out along the bottom surface of the longitudinal groove 311 to the outer peripheral surface of the inner rotating cylinder 31, but this is not a limitation.

[0145] The rotating shaft 32 is fixedly inserted into the inner rotating cylinder 31 and extends to the outer groove 221. In this embodiment, the rotating shaft 32 includes a shaft portion 321 and a turntable portion 322. The shaft portion 321 is inserted into the inner rotating cylinder 31, and one end of the shaft portion 321 protrudes from the inner rotating cylinder 31 towards the handle portion 22. The turntable portion 322 is connected to the outer peripheral surface of the shaft portion 321 and surrounds the shaft portion 321, and the turntable portion 322 is located at the end of the shaft portion 321 facing the handle portion 22. The turntable portion 322 has a plurality of connecting holes 3221 formed through it, and the plurality of connecting holes 3221 are arranged along the periphery of the turntable portion 322 and spaced apart from each other.

[0146] Please refer to the following: Figure 2 , Figure 5 ,and Figure 6 The connecting component assembly 302 is disposed in the outer setting groove 221 and connected to the rotating shaft 32 of the driven component assembly 301. In this embodiment, the connecting component assembly 302 has an outer rotating cylinder 33, a linkage 34, multiple ball sets 35, an anti-cracking component 36, and a clamping component 37.

[0147] Please refer to Figures 5 to 8The outer rotating cylinder 33 is located in the outer groove 221 and can rotate relative to the handle portion 22, and is connected to the rotating shaft 32. The outer rotating cylinder 33 has multiple ball holes 331 and a transverse hole 332. The ball holes 331 penetrate the outer rotating cylinder 33 along its axial direction and are spaced apart along its periphery. The transverse hole 332 is formed in the outer rotating cylinder 33 along its radial direction, and is interconnected with at least one of the ball holes 331. In this embodiment, the opposite ends of the transverse hole 332 are connected to three ball holes 331 respectively, but this is not a limitation.

[0148] Furthermore, in this embodiment, one end face of the outer rotating cylinder 33 is attached to the turntable portion 322 of the rotating shaft 32, and the position of the ball hole 331 corresponds to the position of the linkage hole 3221. The end face of the outer rotating cylinder 33 that contacts the turntable portion 322 has a protruding protrusion 333 that passes through one of the linkage holes 3221 in the turntable portion 322. This allows the outer rotating cylinder 33 to drive the rotating shaft 32 to rotate, but this is not a limitation.

[0149] like Figure 7 As shown, the linkage 34 is movably disposed in the transverse hole 332. The linkage 34 selectively protrudes from the outer peripheral surface of the outer rotating cylinder 33, thereby embedding the linkage 34 into a linkage groove 223 on the inner peripheral surface of the outer mounting groove 221. Specifically, the inner peripheral surface of the outer mounting groove 221 is recessed to form two linkage grooves 223. The two linkage grooves 223 are located at opposite ends of the outer mounting groove 221 in the radial direction, and the positions of the two linkage grooves 223 are aligned with the openings at both ends of the transverse hole 332. The linkage 34 includes two fitting plates 341 and a compression spring 342. The two fitting plates 341 are located at the openings at both ends of the transverse hole 332, and the two ends of the compression spring 342 are connected to the two fitting plates 341 respectively. The rebound force stored in the compression spring 342 tends to push the two fitting plates 341 outward from the outer rotating cylinder 33. When the positions of the two linkage slots 223 and the openings at both ends of the transverse hole 332 are aligned with each other, the compression spring 342 will push the two mating plates 341 out of the outer circumferential surface of the outer rotating cylinder 33 and embed them into the two linkage slots 223 respectively.

[0150] Please refer to Figures 5 to 7Each ball set 35 is respectively disposed in a ball hole 331, and each ball set 35 has a ball rod 351 and a return spring 352. The ball rod 351 is located in the ball hole 331 and can move relative to the outer rotating cylinder 33 along the axial direction of the outer rotating cylinder 33. Specifically, the ball rod 351 can move along the ball hole 331 and pass through the linkage hole 3221 of the turntable portion 322 of the rotating shaft 32. In this embodiment, two of the ball rods 351 disposed in the six ball holes 331 that are interconnected with the transverse hole 332 are simultaneously disposed through the two fitting plates 341 and can also move relative to the fitting plates 341, but this is not a limitation. The ball rod 351 has a receiving groove 3511, which is recessed into the outer peripheral surface of the ball rod 351. Furthermore, the lengths of the pin rods 351 in each pin group 35 may be different, or the positions of the receiving grooves 3511 of each pin rod 351 along the length of the pin rod 351 may be different. When the reset unit 30 is in the reset position, the position of the receiving groove 3511 is aligned with the transverse hole 332, and the linkage 34 is inserted into the receiving groove 3511.

[0151] Among them, such as Figure 20 and Figure 21 As shown, when the receiving groove 3511 of the ball pin 351 is aligned with the transverse hole 332 in the first direction D1 of the housing 1, the fitting plate 341 of the linkage 34 can move into the position of the receiving groove 3511. For details, please refer to... Figure 6 and Figure 7 In this embodiment, when the receiving groove 351 is not aligned with the transverse hole 332, the fitting plate 341 of the linkage 34 will be limited to a position protruding from the outer peripheral surface of the outer rotating cylinder 33 and respectively embedded in the two linkage grooves 223. At this time, if the outer rotating cylinder 33 is rotated, the fitting plate 341 will drive the handle 22 to rotate together; conversely, as Figure 20 and Figure 21 As shown, if the receiving grooves 3511 of the ball rods 351 in the six ball holes 331 that are connected to the transverse hole 332 are all aligned with the transverse hole 332, the receiving grooves 3511 can provide space for the fitting plate 341 to move inward. At this time, the outer rotating cylinder 33 can rotate relative to the handle 22 without causing the handle 22 to rotate together. In this way, the reset unit 30 can rotate relative to the unlocking unit 20 to the reset position. Specifically, when the receiving groove 3511 provides space for the fitting plate 341 to move inward, after the outer rotating cylinder 33 is rotated, the fitting plate 341 will be moved out from 223 and squeezed by the inner circumferential surface of the handle 22, thereby compressing the spring 342 and the fitting plate 341 can move inward along the radial direction of the outer rotating cylinder 33.

[0152] A return spring 352 is sleeved on the pin 351. Specifically, the pin 351 has a contact surface 3512 facing the turntable portion 322. One end of the return spring 352 abuts against the contact surface 3512 of the pin 351, while the other end abuts against the turntable portion 322. The restoring force stored in the return spring 352 can push the pin 351 away from the turntable portion 322, thus restoring it to its original position.

[0153] Please refer to Figure 5 and Figure 6 The anti-hacking component 36 is disposed at one end of the outer rotating cylinder 33 and embedded in the unlocking unit 20. The anti-hacking component 36 has multiple through holes, the positions of which are aligned with the positions of the pin holes 331. In this embodiment, the anti-hacking component 36 is sleeved on the shaft portion 321 of the rotating shaft 32 and fits against the turntable portion 322, thereby allowing the pin rod 351 to pass through the turntable portion 322 and into the through holes of the anti-hacking component 36. The anti-hacking component 36 is embedded in the inner circumferential surface of the outer setting groove 221, thus causing the handle portion 22 to rotate together. If any pin rod 351 passes through the turntable portion 322 into the anti-hacking component 36, the handle portion 22 will be driven to rotate by the outer rotating cylinder 33, thus preventing the reset unit 30 from rotating relative to the unlocking unit 20 to the reset position. The form of the anti-hacking component 36 is not limited to this; for example, it can also be integrally formed with the handle portion 22.

[0154] In this embodiment, the connecting assembly 302 may further include a clamping member 37 disposed in the outer mounting groove 221. The clamping member 37 is a ring with multiple annular ribs formed around its outer circumference. The clamping member 37 is sleeved on the shaft portion 321 of the rotating shaft 32, and the clamping member 37 is embedded between the inner mounting groove 211 and the outer mounting groove 221 by means of the multiple annular ribs on its outer circumference. In this way, the clamping member 37, the anti-cracking member 36, the turntable portion 322 of the rotating shaft 32, and the outer rotating cylinder 33 can abut against each other, preventing gaps from forming between the anti-cracking member 36 and the turntable portion 322, thus preventing them from losing their function.

[0155] Please refer to the following: Figures 2 to 4 , Figure 6 ,and Figure 9 The combination lock assembly 4 is disposed in the receiving cavity 12 and is connected to the lock cylinder assembly 2. The combination lock assembly 4 includes multiple button groups 41, an unlocking drive piece 42, a fixing drive piece 43, a reset drive piece 44, and multiple gaskets 45.

[0156] Please refer to Figures 2 to 4 , Figure 6 , Figures 9 to 11The button group 41 is disposed in the receiving cavity 12. In this embodiment, there are ten button groups 41 to correspond to the Arabic numerals 0 to 9, but the number of button groups 41 is not limited to this. Each button group 41 has a body 411, a guide sleeve 412, and a pressing element group 413.

[0157] The main body 411 extends through and protrudes from the operating surface 11, and is movable along the first direction D1 of the outer casing 1. In this embodiment, the main body 411 is a square rod-shaped member with a first limiting groove 4111, a second limiting groove 4112, and a fixing groove 4113. The first limiting groove 4111 and the second limiting groove 4112 are recessed on the outer surface of the main body 411 and are spaced apart along the first direction D1 of the outer casing 1. The fixing groove 4113 is recessed on the side of the main body 411 facing away from the lock cylinder assembly 2. In this embodiment, the second limiting groove 4112 is located between the operating surface 11 and the first limiting groove 4111 along the first direction D1.

[0158] The guide sleeve 412 is fitted onto the body 411 and is movable relative to the body 411 along a first direction D1. The guide sleeve 412 is selectively located in a first position or a second position relative to the body 411. Specifically, the guide sleeve 412 has a positioning rib 4121 that protrudes from the inner circumferential surface of the guide sleeve 412. The positioning rib 4121 selectively engages with a first limiting groove 4111 or a second limiting groove 4112. When the guide sleeve 412 is in the first position, the positioning rib 4121 engages with the first limiting groove 4111, and when the guide sleeve 412 is in the second position, the positioning rib 4121 engages with the second limiting groove 4112. In this embodiment, the shape of the guide sleeve 412 corresponds to the shape of the body 411 and is a square cylindrical shape, and the guide sleeve 412 has an unlocking engagement groove 4122, which is recessed on the side of the guide sleeve 412 facing the lock core assembly 2. In addition, the end face of the guide sleeve 412 facing the operating surface 11 and the side of the guide sleeve 412 facing away from the lock cylinder assembly 2 have a bevel 4123 to form a bevel structure, but it is not limited to this.

[0159] The pressing assembly 413 is fixed in the receiving cavity 12 and connected to the body 411. Specifically, the pressing assembly 413 is fixed to the side of the outer shell 1 away from the operating surface 11. The pressing assembly 413 can push against the body 411, thereby allowing the body 411 to be selectively positioned in a raised position or a pressed position relative to the receiving cavity 12 along the first direction D1.

[0160] Specifically, the pressing component assembly 413 includes an outer cylinder 4131, a spring 4132, and a displacement component 4133. The inner circumferential surface of the outer cylinder 4131 has ribs formed along its axial direction, and the axial direction of the outer cylinder 4131 is parallel to the first direction D1. The spring 4132 is connected to a bottom surface inside the outer cylinder 4131 and the displacement component 4133, and the spring 4132 is extendable and retractable along the first direction D1. The displacement component 4133 is movably disposed within the outer cylinder 4131. The outer circumferential surface of the displacement component 4133 has multiple straight grooves penetrating along the first direction D1, and multiple inclined grooves that are inclined to the first direction D1 but not completely penetrating; the straight grooves and inclined grooves are alternately arranged along the circumferential direction of the displacement component 4133. Each time the displacement member 4133 is pressed into the bottom surface of the outer cylinder 4131 and then pushed out by the spring 4132, the displacement member 4133 rotates, causing the ribs of the outer cylinder 4131 to switch between straight grooves and inclined grooves. Since the straight grooves and inclined grooves have different lengths in the first direction D1, the displacement member 4133 can be positioned at two different positions relative to the outer casing 1 in the first direction D1. The body 411 abuts against the displacement member 4133, thus the body 411 can be positioned with the assistance of the two different positions of the displacement member 4133. Figure 14 and Figure 17 The lifting position (body 411A) and pressing position (body 411B) are shown in the diagram.

[0161] The unlocking actuator 42 is located within the receiving cavity 12. The button assembly 41 passes through the unlocking actuator 42 along a first direction D1. The unlocking actuator 42 is movable relative to the outer casing 1 along a second direction D2, thereby selectively engaging with the guide sleeve 412 of the button assembly 41. Specifically, the unlocking actuator 42 has multiple unlocking ribs 421 and an unlocking end 422. The guide sleeves 412 are located above the unlocking ribs 421. Figure 14 As shown, when all the unlocking engagement grooves 4122 of the guide sleeves 412 are aligned with the unlocking ribs 421 in the first direction D1, the unlocking drive piece 42 can move away from the lock core assembly 2 relative to the outer shell 1 in the second direction D2, so that all the unlocking ribs 421 enter the unlocking engagement grooves 4122 of the guide sleeves 412, and the unlocking drive piece 42 and the guide sleeves 412 engage with each other.

[0162] The unlocking end 422 is disposed on the side of the unlocking drive piece 42 facing the lock cylinder assembly 2, and the unlocking end 422 abuts against the unlocking unit 20. In this embodiment, the unlocking end 422 is a rod-shaped body, the end facing the lock cylinder assembly 2 is a pointed tip, and it selectively passes through the side groove 213. The unlocking end 422 can slide along the bottom surface of the side groove 213.

[0163] The fixed drive plate 43 is located within the receiving cavity 12, and the button assembly 41 passes through the fixed drive plate 43 along the first direction D1. The fixed drive plate 43 can move relative to the outer shell 1 along the second direction D2, thereby selectively engaging with the body 411. Specifically, the fixed drive plate 43 has multiple fixing ribs 431 and a fixing end 432. The body 411 of each button assembly 41 is located below the fixing ribs 431, such as... Figure 22 As shown, when all the fixing grooves 4113 of the main body 411 are aligned with the fixing ribs 431 in the first direction D1, the fixing drive piece 43 can move relative to the outer shell 1 along the second direction D2 to approach the lock core assembly 2, so that all the fixing ribs 431 enter the fixing grooves 4113 of the main body 411, so that the fixing drive piece 43 and the main body 411 are engaged with each other. At this time, the main body 411 is fixed and cannot move relative to the outer shell 1 along the first direction D1.

[0164] The fixed end 432 is disposed on the side of the fixed driving piece 43 facing the lock cylinder assembly 2, and the fixed end 432 abuts against the unlocking unit 20 and selectively passes through the side through hole 212. Similarly, in this embodiment, the fixed end 432 is a rod-shaped body, with its end facing the lock cylinder assembly 2 abutting against the pad 23. An elastic element is provided on the side of the fixed end 432 away from the lock cylinder assembly 2. The elastic element pushes the fixed driving piece 43 to move towards the lock cylinder assembly 2. Therefore, when the longitudinal groove 311 of the inner rotating cylinder 31 is aligned with the side through hole 212 of the annular wall portion 21, the fixed end 432 can push the pad 23 to move inward and sink into the longitudinal groove 311. At this time, the fixed end 432 passes through the side through hole 212. However, please refer to Figure 12 When the invention is in the unlocked state, the fixed end 432 abuts against the outer peripheral surface of the annular wall portion 21.

[0165] The reset actuating piece 44 is located in the receiving cavity 12 and is sleeved on the key assembly 41. The reset actuating piece 44 can move relative to the outer shell 1 along the second direction D2, thereby pushing the guide sleeve 412 located in the second position to move relative to the outer shell 1 along the first direction D1 to the first position. The reset actuating piece 44 has a plurality of inclined abutment blocks 441 and a reset end 442. The inclined abutment blocks 441 are respectively disposed next to the key assembly 41, and each inclined abutment block 441 and the guide sleeve 412 of the corresponding key assembly 41 are spaced apart in the second direction D2. Specifically, each inclined abutment block 441 has an inclined pushing surface 4411 facing the corresponding key assembly 41, the inclined pushing surface 4411 extends along the first direction D1 and is inclined away from the corresponding key assembly 411. When the reset actuating piece 44 pushes the guide sleeve 412, the inclined pushing surface 4411 of the inclined abutment block 441 pushes against the end of the guide sleeve 412 of the corresponding key assembly 41 facing the operating surface 11. In this embodiment, the inclined push surface 4411 pushes against the end face of the guide sleeve 412 facing the operating surface 11 and the inclined surface 4123 between the side of the guide sleeve 412 facing away from the lock core assembly 2, but is not limited thereto.

[0166] The reset end 442 is disposed on the side of the reset drive piece 44 facing the lock cylinder assembly 2, and the reset end 442 abuts against the unlocking unit 20 and selectively passes through the side through hole 212. Similarly, in this embodiment, the reset end 442 is a rod-shaped body, with its end facing the lock cylinder assembly 2 abutting against the pad block 23. The reset end 442 is fitted with a pressing part 443 on the side away from the lock cylinder assembly 2, and the pressing part 443 protrudes from the outer shell 1 along the second direction D2. When the longitudinal groove 311 of the inner rotating cylinder 31 aligns with the side through hole 212 of the annular wall portion 21, the reset end 442 can push the pad 23 inward to sink into the longitudinal groove 311 and pass through the side through hole 212; in other words, at this time the longitudinal groove 311 provides space for the reset driving piece 44 to move, so the user can press the pressing part 443 of the reset driving piece 44 to move the reset driving piece 44 relative to the outer shell 1 in the second direction D2, further pushing the guide sleeve 412 located in the second position to the first position. However, please refer to Figure 12 When the present invention is in the unlocked state, the reset end 442 abuts against the outer peripheral surface of the annular wall portion 21.

[0167] Multiple gaskets 45 are disposed between the unlocking drive plate 42 and the fixed drive plate 43, and between the unlocking drive plate 42 and the reset drive plate 44, thereby fixing the relative positions of the unlocking drive plate 42, the fixed drive plate 43, and the reset drive plate 44 in the first direction D1, but not limited thereto.

[0168] Please refer to Figures 1 to 4 and Figure 6The lock head 5 is disposed through the outer casing 1 and connected to the unlocking unit 20, and is used to secure the locked object, such as a cabinet door or drawer. In this embodiment, the lock head 5 is connected to the annular wall portion 21, thereby enabling the unlocking unit 20 to drive the lock head 5 to rotate.

[0169] Please refer to Figure 2 , Figure 18 ,and Figure 20 The reset device 6 is used to connect the reset unit 30 of the lock cylinder assembly 2. Specifically, the reset device 6 can be connected to the coupling assembly 302, pushing the pin rod 351 to align the receiving groove 3511 with the transverse hole 332 in the first direction D1, so that the reset unit 30 can rotate relative to the unlocking unit 20 to the reset position. In this embodiment, the reset device 6 is a key, which is inserted into the lock hole 222 of the handle 22, but is not limited thereto.

[0170] Please refer to Figures 13 to 15 In this invention, when the main body 411A of the button assembly 41 is in the raised position and the guide sleeve 412 is in the first position, the unlocking engagement groove 4122 of the guide sleeve 412 is aligned with the unlocking rib 421 of the unlocking drive piece 42 in the first direction D1 relative to the outer shell 1; conversely, when the main body 411B of the button assembly 41 is in the pressed position and the guide sleeve 412 is in the second position, the unlocking engagement groove 4122 of the guide sleeve 412 is aligned with the unlocking rib 421 of the unlocking drive piece 42 in the first direction D1 relative to the outer shell 1, thereby allowing the user to set a password.

[0171] Rotating the handle 22 to the side groove 213 of the ring wall 21 will push the unlocking end 422 of the unlocking drive piece 42 to the outer diameter of the ring wall 21 by means of the inclined surface, so that all the unlocking ribs 421 of the unlocking drive piece 42 enter the unlocking engagement groove 4122 of the guide sleeve 412. At this time, not only is the unlocking purpose achieved, but the guide sleeve 412 is also restricted by the unlocking drive piece 42 and cannot move along the first direction D1. At this time, the password can be changed by pressing the body 411 to change its raised position (body 411A) or pressed position (411B), instead of having to open the cabinet door or drawer or other locked items and change the password from the back of the door panel as in conventional technology. Therefore, the present invention makes it convenient for users to change the password from the operating surface 11.

[0172] Please refer to the following: Figure 6 , Figure 11 ,and Figure 17When the invention is in the locked state, the unlocking end 422 is located in the side groove 213 while the fixed end 432 abuts against the pad 23. Since the fixed rib 431 does not obstruct the movement of the body 411 in the first direction D1, the user can freely press the button group 41 from the operating surface 11 to switch each body 411 between the raised position (body 411A) and the pressed position (body 411B). As long as the unlocking engagement grooves 4122 of all guide sleeves 412 are not simultaneously aligned with the unlocking rib 421, the unlocking drive piece 42 cannot move along the second direction D2. Therefore, the unlocking unit 20 is blocked by the unlocking end 422 and cannot rotate, thereby preventing the lock head 5 from rotating.

[0173] Please refer to the following: Figures 12 to 15 When the invention is in the unlocked state, all the unlocking engagement grooves 4122 of the guide sleeves 412 are aligned with the unlocking ribs 421, providing space for the unlocking drive piece 42 to move. Therefore, when the user operates the handle 22 to rotate the unlocking unit 20, the bottom surface of the side groove 213 can push the unlocking end 422, causing the unlocking drive piece 42 to move. At this time, the handle 22 can rotate normally, and drive the lock head 5 to rotate together. In addition, in the unlocked state, the unlocking drive piece 42 is engaged with the guide sleeve 412, preventing the guide sleeve 412 from moving along the first direction D1. However, the fixed drive piece 43 is not engaged with the body 411. Therefore, the user can press the body 411 to further move the body 411 relative to the guide sleeve 412, thereby switching the guide sleeve 412 to the first position or the second position relative to the body 411 to set the password.

[0174] Please refer to the following: Figures 18 to 22 This is the case where the present invention is in the reset state. When the present invention is locked, the user can insert the reset device 6. The reset device 6 is connected to the reset unit 30 through the lock hole 222. Pushing the pin rod 351 will align the receiving groove 3511 with the transverse hole 332 in the first direction D1, so that the fitting plate 341 can be pressed inward. In addition, the pin rod 351 at this time passes through the outer rotating cylinder 33 and enters the linkage hole 3221 of the rotating part 322 of the rotating shaft 32, but does not extend into the through hole of the anti-cracking part 36. Therefore, at this time, the reset unit 30 can rotate relative to the unlocking unit 20 to the reset position, that is, the inner rotating cylinder 31 rotates relative to the annular wall part 21 until the longitudinal groove 311 is aligned with the two through holes 212, and the two pads 23 are pushed into the longitudinal groove 311 by the combination plate assembly 4.

[0175] When the reset unit 30 is in the reset position, the longitudinal groove 311 of the inner rotating cylinder 31 is aligned with the side through hole 212 of the annular wall portion 21. When all the bodies 411 of the button group 41 are in the raised position, the fixing engagement grooves 4113 of all the bodies 411 are aligned with the fixing ribs 431, providing space for the fixing drive piece 43 to move in the second direction D2. Therefore, the fixing drive piece 43 is pushed towards the lock cylinder assembly 2 and engages with all the bodies 411, preventing the bodies 411 from moving in the first direction D1. At this time, the fixing end 432 passes through the unlocking unit 20.

[0176] Since the unlocking unit 20 is not rotating, the unlocking drive piece 42 and the guide sleeve 412 are separated, allowing the guide sleeve 412 to move relative to the body 411. The user can then press the pressing part 443 of the reset drive piece 44, causing it to move along the second direction D2. The reset end 442 of the reset drive piece 44 passes through the unlocking unit 20, pushing against the guide sleeve 412. This positions each guide sleeve 412 in the first position, which is the reset state of the invention. In this way, all guide sleeves 412 in the second position will be pushed to the first position by the reset drive piece 44, thus completing the password reset and restoring the device to its factory initial state.

[0177] As mentioned above, the lengths of the pin rods 351 in each pin group 35 of this invention may be different, or the positions of the receiving grooves 3511 of each pin rod 351 in the first direction D1 may be different. Therefore, a matching reset device 6 is required to align the receiving grooves 3511 in the first direction D1 with the transverse hole 332, allowing the mating plate 341 to be pressed inward. If a malicious person uses other methods to push the pin rod 351, it may pass through the turntable part 322 and extend into the anti-hacking component 36. Since the anti-hacking component 36 is embedded in the unlocking unit 20, if a malicious person tries to rotate the reset unit 30, the unlocking unit 20 will also be moved. However, because the unlocking drive piece 42 is blocked by the guide sleeve 412, the unlocking unit 20 cannot rotate, which in turn prevents the reset unit 30 from rotating, thus preventing malicious persons from hacking it.

[0178] This invention, through the structure of the reset device 6 and reset unit 30 combined with the keypad assembly 4, allows users to reset their passwords and restore them to the factory default state when they forget them, thus solving the problem of not being able to reset passwords when forgotten. Furthermore, the reset device 6, connected to the reset unit 30, and the keypad assembly 41 are both integrated on the operation surface 11, unlike conventional technologies where forgetting the password renders the device unusable. Therefore, this invention facilitates password reset and restoration to the factory default state for users. Simultaneously, this invention incorporates anti-cracking design to prevent malicious individuals from cracking the invention by resetting the password.
