Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting technology, and more particularly, to a password lock, a tag assembly, and a bottle cap assembly. Background Art

[0002] At present, as a carrier of anti-counterfeiting codes, two-dimensional codes have many advantages such as low cost, simple use, and powerful expansion. The query rate is the key factor for whether an anti-counterfeiting code can prevent counterfeiting. The higher the query rate, the better the anti-counterfeiting effect. Currently, the query rate of two-dimensional codes is generally less than 5%. Due to the too low scanning rate, the natural advantages of two-dimensional codes in anti-counterfeiting cannot be applied at all. By installing a password lock device on the product or its packaging and guiding consumers to obtain the unlocking password by querying the anti-counterfeiting code, the query rate of the anti-counterfeiting code is high and the anti-counterfeiting effect is good. If an ordinary password lock is used for installing the password lock device, the structure is complex, the volume is large, and the cost is high. It is difficult to integrate with the product to be anti-counterfeited and is not conducive to large-scale application in product anti-counterfeiting.

[0003] After research by the inventor, it is found that the existing password locks for guiding users to scan anti-counterfeiting codes have the following disadvantages:

[0004] Complex structure, large volume, and high cost. Summary of the Invention

[0021] In an alternative embodiment, the tag component further includes a locking rope and a linkage locking component. The first end of the locking rope is fixed to the linkage locking component, and the second end of the locking rope is unlockably connected to the linkage locking component. The linkage locking component is connected to the password lock. The linkage locking component has a locking state and an unlocking state that switch between each other. When in the locking state, the movement of pulling the second end away from the linkage locking component is restricted. When in the unlocking state, the second end can be pulled away from the linkage locking component.

[0022] The password lock is used to make the linkage locking component in the unlocking state when in the first position, and to make the linkage locking component in the locking state when in the second position.

[0023] In an alternative embodiment, the linkage locking component includes a lock block, a locking wheel, and a second elastic member. The lock block is connected to the limiting member.

[0030] The beneficial effects of the embodiments of the present invention are:

[0031] In summary, for the password lock provided in this embodiment, the locking convex portion provided on the limiting member not only functions as a locking tongue but also has the function of restricting the position of the lock disc so that the lock disc will not come out of the assembly hole. That is to say, the functions of the limiting member are diversified, integrating multiple functions into one. Compared with arranging an independent locking tongue and a limiting structure for restricting the position of the lock disc at intervals in the axial extension direction of the assembly hole, it is possible to reduce the thickness of the password lock in the axial extension direction of the assembly hole, which is beneficial to the miniaturization of the product volume, making the product structure compact and small in volume. Moreover, the structure for restricting the lock disc is provided on the limiting member, simplifying the structure of the lock shell.

[0052] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] Currently, as a carrier of anti-counterfeiting codes, two-dimensional codes have a wide range of applications. However, since the query rate of two-dimensional codes by users after purchasing products is generally less than 5%, the application of two-dimensional code anti-counterfeiting is not ideal enough. Currently, in the market, in order to increase the query rate of two-dimensional codes, a method of installing a password lock at the two-dimensional code is adopted to guide users to scan the two-dimensional code. In the prior art, the structure of the password lock is complex, the volume is large, the cost is high, and the matching effect with the product is poor.

[0059] In view of this, the designer has designed a password lock that can simplify the structure, reduce the volume, lower the cost, require less space, and is convenient to be perfectly combined with the product.

[0060] Please refer to Figures 1 - 5In this embodiment, the combination lock includes a lock housing 100 and a lock assembly 200. The lock housing 100 is provided with a positioning hole 140 and an assembly hole 111 connected to the positioning hole 140; the lock assembly 200 includes a limit member 210 and a lock disk 220. The limit member 210 is provided with a lock protrusion 211. The limit member 210 is slidably provided in the positioning hole 140 to switch between a first position and a second position; the lock disk 220 is passed through the assembly hole 111, and the lock disk 220 is provided with a lock recess 223 and a limit member 224; the limit member 224 abuts against the lock protrusion 211 to limit the lock disk 220 from disengaging from the assembly hole 111.

[0061] In the first position, the lock protrusion 211 engages with the lock recess 223 to restrict the lock disk 220 from rotating relative to the lock housing 100, and the combination lock is now unlocked. In the second position, the lock protrusion 211 and the lock recess 223 are separated, allowing the lock disk 220 to rotate relative to the lock housing 100. The position-limiting member 210 cannot slide relative to the lock housing 100, and the combination lock is now locked.

[0062] The working principle of the password lock provided in this embodiment is as follows:

[0063] In the initial state, the locking recess 223 on the lock disk 220 is separated from the locking protrusion 211 on the stopper 210, that is, the stopper 210 is in the second position. At this time, the lock disk 220 can rotate freely relative to the lock housing 100, and the stopper 210 cannot slide in the positioning hole 140 relative to the lock housing 100 in the set direction. In other words, in this state, the combination lock is in a locked state, and the user cannot open the combination lock without obtaining the unlocking code. When the combination lock needs to be opened, the user can obtain the unlocking code of the combination lock through phone calls, text messages or scanning codes, and then rotate the lock disk 220 to align the corresponding unlocking information on the lock disk 220 with the identification position on the lock shell 100. When multiple lock disks 220 are rotated to the set position according to the unlocking code, at this time, the lock protrusion 211 and the lock recess 223 are facing each other, providing conditions for the sliding of the limit member 210, that is, when force is applied to the limit member 210 to make it slide in the set direction relative to the lock shell 100, the lock protrusion 211 and the lock recess 223 are plugged into each other, and the limit member 210 can slide the set distance to achieve unlocking.

[0064] Meanwhile, for the password lock in this embodiment, since the lock protrusion 211 provided on the limiting member 210 has both the function of a lock tongue and the function of restricting the position of the lock disc 220 so that the lock disc 220 will not come out of the assembly hole 111, that is to say, the function of the limiting member 210 is diversified, integrating multiple functions into one, reducing the number of components, lowering the assembly difficulty, and reducing the manufacturing cost. Compared with arranging an independent lock tongue and a limiting structure for restricting the position of the lock disc 220 at intervals in the axial extension direction of the assembly hole 111, it can reduce the thickness of the password lock in the axial extension direction of the assembly hole 111, which is beneficial to the miniaturization of the product volume, making the product structure compact and small in volume. Moreover, the structure for restricting the lock disc 220 is arranged on the limiting member 210, simplifying the structure of the lock shell 100. The assembly hole 111 of the lock shell 100 is only used to position the circumferential rotation of the lock disc 220, and the lock disc 220 can be maximally exposed outside the lock shell 100, so as to facilitate printing the unlocking information on the surface of the lock disc 220 after the password lock is assembled, creating conditions for realizing the automation of password setting.

[0065] In this embodiment, it should be noted that the unlocking information can be digital information, text information, pattern information, etc., which will not be listed one by one in this embodiment.

[0066] Moreover, the unlocking information of the password lock provided in this embodiment can be designed on the disk surface of the lock disc 220 by means of printing or the like after the password lock is assembled. In this way, the unlocking information of the password lock can be designed automatically, and the design is more convenient and reliable.

[0067] Please refer to Figure 1 , in this embodiment, optionally, the lock shell 100 is provided as a split structure. The lock shell 100 includes a first half shell 110 and a second half shell 120, and the first half shell 110 and the second half shell 120 are snap-connected and can be fixed by fasteners such as screws. After the first half shell 110 and the second half shell 120 are snap-connected, they jointly define a positioning hole 140. Further, the lock shell 100 formed by the first half shell 110 and the second half shell 120 is a long strip-shaped shell, and the positioning hole 140 is a long strip-shaped channel that extends along a preset straight line. Two assembly holes 111 are provided on the first half shell 110, and the two assembly holes 111 are arranged at intervals on the preset straight line. Two notches 112 are also provided on the first half shell 110, and the two notches 112 communicate with the two assembly holes 111 respectively. Specifically, each notch 112 penetrates through a part of the hole wall of the assembly hole 111. In other words, each assembly hole 111 has a first port and a second port. The first port is located on the side of the second port away from the second half shell 120. The notch 112 is located on the end face corresponding to the first port, and there is a distance between the notch 112 and the second port in the axial extension direction of the assembly hole 111.

[0068] It should be understood that the number of the assembly holes 111 on the first half shell 110 and the number of the notches 112 are both set as required, not limited to one or two, etc., and can also be three, four or five, etc. The number of the assembly holes 111 is equal to and corresponds one by one with the number of the notches 112, and it is only necessary that the number of the assembly holes 111, the number of the notches 112 and the number of the lock plates 220 are equal to and correspond one by one. In addition, the assembly holes 111 can be set as cylindrical holes, etc.

[0069] Optionally, the second half shell 120 has an inner surface facing the first half shell 110. After the first half shell 110 and the second half shell 120 are assembled, the axis of the assembly hole 111 is perpendicular to the inner surface. Two damping portions 160 are arranged on the inner surface, and the two damping portions 160 correspond to the two assembly holes 111. Each damping portion 160 can be set as a plastic block, a rubber block, etc. The damping portion 160 corresponds to the lock plate 220 passing through the assembly hole 111 and can be attached to the outer surface of the lock plate 220, so as to prevent the lock plate 220 from automatically rotating and improve the user's hand feeling. It should be understood that the number of the damping portions 160 is not limited to two, and at least one damping portion 160 corresponds to each lock plate 220. For example, in this embodiment, one lock plate 220 corresponds to one damping portion 160.

[0070] Furthermore, two rotating shafts 130 are arranged on the inner surface of the second half shell 120. The two rotating shafts 130 respectively correspond to the two assembly holes 111 one by one, and the corresponding assembly hole 111 and the rotating shaft 130 are coaxially arranged. Each rotating shaft 130 is used to position the lock plate 220, and the lock plate 220 can rotate around the rotating shaft 130.

[0071] It should be understood that after the lock plate 220 passes through the assembly hole 111, the movement of the lock plate 220 in the axial extension direction of the assembly hole 111 is restricted by the limiting member 210, and there is no need to arrange a structure on the first half shell 110 or the second half shell 120 to limit the movement of the lock plate 220 in the axial extension direction of the assembly hole 111. In this way, the structure of the lock shell 100 is simple, which is beneficial to processing and manufacturing and can reduce the manufacturing cost. Moreover, the assembly hole 111 can be set as a cylindrical hole, and the assembly hole 111 is an equal-diameter hole without the need to set a stepped diameter section, which is also beneficial to the processing and manufacturing of the lock shell 100.

[0072] Please refer to Figure 3, in this embodiment, optionally, the limiting member 210 is arranged in a plate-like structure, that is, the limiting member 210 can be called a limiting plate. The limiting member 210 is a long strip plate. After the limiting member 210 is assembled in the positioning hole 140, the length direction of the limiting member 210 extends along a preset straight line. The limiting member 210 has two plate surfaces in its thickness direction and a first side surface 212 and a second side surface 213 in its width direction. It should be understood that the straight line where the thickness direction is located, the straight line where the width direction is located, and the preset straight line are perpendicular to each other in pairs. Among them, the thickness direction can also be understood as the extending direction of the axis of the assembly hole 111. Two avoidance grooves 214 are arranged on the first side surface 212 of the limiting member 210 at intervals in its length direction. Each avoidance groove 214 is an arc-shaped groove, and moreover, the cross-sectional contour of each avoidance groove 214 is approximately a major arc, that is, the width of the notch of the avoidance groove 214 is smaller than the diameter of the cylinder where the avoidance groove 214 is located. A locking convex portion 211 protrudes from the groove wall of each avoidance groove 214. The locking convex portion 211 is a rectangular parallelepiped block, and the length direction of the locking convex portion 211 extends along the length direction of the limiting plate.

[0073] Please refer to Figure 4 , in this embodiment, optionally, the lock disk 220 includes a disk body 221 and a connecting shaft 222. The disk body 221 is a disk, and anti-slip grooves are arranged on the outer peripheral surface of the disk body 221. One end surface of the connecting shaft 222 is fixed on the disk body 221 and they are coaxially arranged. The locking concave portion 223 is arranged as a groove on the outer peripheral surface of the connecting shaft 222. The limiting portion 224 is connected to the connecting shaft 222 and protrudes from the outer peripheral surface of the connecting shaft 222. The locking concave portion 223 is located between the limiting portion 224 and the disk body 221. Moreover, the limiting portion 224 is arranged as an annular plate. The limiting portion 224 is fixedly connected to the end surface of the connecting shaft 222 far from the disk body 221 and they are coaxially arranged. The outer peripheral surface of the limiting portion 224 protrudes from the outer peripheral surface of the connecting shaft 222, and a plurality of concave-convex structures 2241 are arranged on the outer peripheral surface of the limiting portion 224. In other words, the limiting portion 224 can be understood as a kind of gear structure, and the concave-convex structures 2241 can be abutted against the damping portion 160 on the second half shell 120, so as to improve the feel when rotating the lock disk 220 and prevent the lock disk 220 from rotating randomly, reducing the difficulty of unlocking. The lock disk 220 has a rotation hole, the rotation hole is a blind hole, the opening end of the rotation hole is located at the middle position of the limiting portion 224, and the closed end of the rotation hole extends into the connecting shaft 222. During assembly, the lock disk 220 is sleeved outside the corresponding rotation shaft 130 by using the opening end of the rotation hole.

[0074] The assembly method of the password lock provided in this embodiment includes, for example:

[0075] Please refer to Figures 1 - 6First, the limiting member 210 is moved from the sides of the two lock disks 220 toward the lock disks 220 using the notches of its avoidance grooves 214, so that the limiting member 210 is engaged with the two lock disks 220. The locking protrusion 211 of the limiting member 210 is located between the disk body 221 and the limiting portion 224, and the locking protrusion 211 of the limiting member 210 is inserted into the locking recess 223 on the connecting shaft 222. The combination lock is in the unlocked state, and the limiting member 210 will not be separated from the lock disks 220 in the extension direction of the connecting shaft 222. Then, the two lock disks 220 are simultaneously inserted obliquely into the two assembly holes 111 of the first half shell 110, and the second half shell 120 is then snapped onto the first half shell 110, and the two lock disks 220 are respectively sleeved onto the corresponding rotation shafts 130 on the second half shell 120 using the rotation holes. The two assembly holes 111 on the first half shell 110 correspond to the two disk bodies 221 of the lock disk 220, so that the disk bodies 221 are embedded in the two assembly holes 111, and the disk bodies 221 are partially located in the notch 112, making it easy to move the lock disk 220 through the notch 112 to rotate. After the combination lock is assembled, the unlocking information is printed or otherwise provided on the disk surface of the disk body 221 away from the second half shell 120. Since the first half shell 110 does not need to be designed with a structure that restricts the dial from escaping from the assembly hole 111, the assembly hole 111 can be set as an equal-diameter hole. After the disk body 221 is embedded in the assembly hole 111, the disk surface of the disk body 221 used to print the unlocking information can be completely exposed to the external environment. That is, the orthographic projection of the disk surface used to print the unlocking information in the axial extension direction of the assembly hole 111 is located in the area surrounded by the opening of the assembly hole 111 away from the positioning hole 140. The disk surface of the disk body 221 used to print the unlocking information is completely exposed to the external environment, which is conducive to printing the unlocking information on the disk surface.

[0076] At the same time, the first half shell 110 does not need to be provided with a structure that restricts the dial from being dislodged from the assembly hole 111, and the assembly hole 111 does not need to be provided as a stepped hole. The thickness of the first half shell 110 in the direction of the axial extension of the assembly hole 111 remains consistent. Under the premise of the same thickness, the strength of the first half shell 110 provided with an assembly hole 111 of equal diameter is greater than the strength of the first half shell 110 provided with a stepped assembly hole 111. In this way, the lock case 100 has high structural strength and is not easily damaged. In other words, when the assembly hole 111 is provided as a stepped hole, the hole wall of the smaller hole diameter portion of the first half shell 110 that encloses the assembly hole 111 is inwardly protruded relative to the hole wall of the larger hole diameter portion. The thickness of the smaller hole diameter portion of the first half shell 110 that constitutes the assembly hole 111 is reduced compared to the total thickness of the first half shell 110, and the structural strength of this portion is low and it is easily damaged.

[0077] It should be understood that when the lock disk 220 is inserted into the avoidance groove 214 , the lock protrusion 211 and the plate surface where the avoidance groove 214 is located cooperate to restrict the lock disk 220 from falling out of the assembly hole 111 , thereby achieving a good anti-falling effect.

[0078] In this embodiment, optionally, the lock assembly 200 further includes a first elastic member 230. The first elastic member 230 is clamped between the limiting member 210 and the lock housing 100, and is used to make the limiting member 210 have a tendency to slide in the direction from the second position to the first position. That is to say, when the password lock is in the unlocked state, under the action of the first elastic member 230, the lock convex portion 211 always remains in the position where it abuts against the outer peripheral surface of the connecting shaft 222. When the user obtains the unlocking information and rotates the lock dial 220 to the position corresponding to the unlocking information, at this time, the lock convex portion 211 is aligned with the lock concave portion 223. Under the action of the first elastic member 230, the lock convex portion 211 can automatically enter the lock concave portion 223 to achieve automatic unlocking, making the unlocking more convenient and fast.

[0079] It should be noted that the first elastic member 230 can be a spring, a spring sheet or a rubber member, etc. Specifically, the first elastic member 230 is a spring. One end of the first elastic member 230 abuts against the inner side wall of the second half shell 120, and the other end abuts against one side wall in the length direction of the limiting member 210.

[0080] Please refer to Figures 6 - 7 , in other embodiments, optionally, the password lock further includes a anti-retreat member 300. The anti-retreat member 300 is provided with a pre-fracture portion 310. The anti-retreat member 300 is connected to the first half shell 110 of the lock housing 100. The pre-fracture portion 310 is clamped between the side wall of the first half shell 110 and the limiting member 210, so that when the limiting member 210 is in the first position, the movement of the limiting member 210 in the direction from the first position to the second position is blocked. That is to say, through the anti-retreat member 300, the limiting member 210 can always be kept in the first position, that is, the password lock can always be kept in the unlocked state. The pre-fracture portion 310 is used to fracture under an external force so that the limiting member 210 can move from the first position to the second position. By providing the anti-retreat member 300, when setting the unlocking information of the password lock, through the structural design of the anti-retreat member 300, the limiting member 210 can always be in the position where the lock convex portion 211 is inserted into the lock concave portion 223, and the password lock can be kept in the unlocked state, avoiding the situation that the dial rotates during the setting of the unlocking information, resulting in incorrect unlocking information and the password lock cannot be opened. The setting of the unlocking information is more secure and reliable. After the unlocking information is set, apply force to the lock housing 100 and the limiting member 210 to make them slide relative to each other. Under the external force, the pre-fracture portion 310 fractures and loses the function of blocking the movement of the limiting member 210 from the first position to the second position, and the password lock can be adjusted to the locked state and can be used normally.

[0081] The password lock provided by this embodiment has a simple structure and is convenient for processing and manufacturing.

[0082] Please refer to Figures 8 - 12, this embodiment also provides a tag component 001, which includes a locking rope 101, a linkage locking component 102, and the above password lock. The first end 1011 of the locking rope 101 is fixed on the linkage locking component 102, and the second end 1012 of the locking rope 101 is unlockably connected to the linkage locking component 102; the linkage locking component 102 has a locking state and an unlocking state that can be switched to each other. When in the locking state, the movement of the second end 1012 being pulled away from the linkage locking component 102 is restricted, that is, the locking rope 101 cannot be pulled out from the linkage locking component 102; when in the unlocking state, the second end 1012 can be pulled away from the linkage locking component 102. The password lock is used to make the linkage locking component 102 in the unlocking state when in the first position, and is used to make the linkage locking component 102 in the locking state when in the second position. That is to say, the state of the linkage locking component 102 is automatically adjusted according to the state of the password lock. When the password lock is in the unlocking state, the locking rope 101 can be pulled out from the linkage locking component 102, so as to remove the tag from the clothing or other items. When the password lock is in the locking state, the locking rope 101 cannot be pulled away from the linkage locking component 102, and the tag cannot be removed from items such as clothing, and the user needs to obtain the unlocking password and perform the unlocking action.

[0083] It should be understood that when the tag component 001 is combined with items such as clothing, the tag can be suspended on the item by using the locking rope 101.

[0084] Optionally, the interlocking locking assembly 102 includes a locking block 1021, a locking wheel 1022, and a second elastic member 1028. The locking block 1021 is connected to the limiting member 210. In this embodiment, the locking block 1021 and the limiting member 210 are integrally formed, and the locking block 1021 or the limiting member 210 can extend out of the lock housing 100. Specifically, an open end 150 is provided on the side of the lock housing 100. The locking block 1021 is inserted into the open end 150 and can reciprocate relative to the open end 150 under the drive of the limiting member 210. Furthermore, the locking block 1021 is provided with a locking hole 1023 and a guide hole 1024. The locking hole 1023 has a first locking surface 1025 and a second locking surface 1026 at an angle. The distance between the first locking surface 1025 and the second locking surface 1026 gradually decreases from the side closest to the limiting member 210 to the other side. A locking groove 1027 is provided on the first locking surface 1025, and the guide hole 1024 communicates with the locking groove 1027. A locking wheel 1022 and a second elastic member 1028 are both disposed within the locking hole 1023. The second elastic member 1028 is located on the side of the locking wheel 1022 away from the guide hole 1024, and is configured to cause the locking wheel 1022 to move toward the guide hole 1024, thereby pressing the locking wheel 1022 against the lock rope 101 and providing initial friction between the locking wheel 1022 and the lock rope 101. The locking wheel 1022 is partially embedded in the locking groove 1027, so that the locking wheel 1022 and the bottom wall of the locking groove 1027 jointly define a locking channel. Obviously, in other embodiments, the locking wheel 1022 may not be embedded in the locking groove 1027, but may simply abut against the lock rope 101. The second end 1012 is disposed within the guide hole 1024 and the locking channel. The lock shell 100 is provided with a limiting protrusion 170 for abutting against the locking wheel 1022. Optionally, a limiting protrusion 170 can be provided on both the first half shell 110 and the second half shell 120. Both limiting protrusions 170 can abut against the locking wheel 1022, thereby cooperating to limit the position of the locking wheel 1022, and the limiting effect is good. When the limiting member 210 is in the second position, that is, when the combination lock is in the locked position, a gap exists between the locking wheel 1022 and the limiting protrusion 170 in the sliding direction of the limiting member 210, so that the locking wheel 1022 can slide close to the guide hole 1024 or the limiting protrusion 170 under the pull of the lock rope 101, so that the locking wheel 1022 can press the lock rope 101 under the action of the second locking surface 1026. When the force used to pull the lock rope 101 to disengage the second end 1012 of the lock rope 101 from the guide hole 1024 is greater, the force of the locking wheel 1022 to lock the lock rope 101 is greater, thereby locking the lock rope 101. In other words, when the limiting member 210 is in the locked state, the limiting member 210 will not slide relative to the lock housing 100, the locking block 1021 and the limiting member 210 are an integral structure, and the position of the locking block 1021 relative to the lock housing 100 will not change.When the second end 1012 of the locking rope 101 is pulled to have a tendency to leave the guiding hole 1024, under the action of the initial frictional force, the second end 1012 drives the locking wheel 1022 to move closer to the guiding hole 1024. Since the second locking surface 1026 is an inclined surface and its position does not change, the second locking surface 1026 can apply a pressing force to press the locking rope 101 on the locking wheel 1022. The greater the force for pulling the locking rope 101, the greater the pressing force of the locking wheel 1022 on the locking rope 101, making it impossible for the locking rope 101 to be pulled out from the guiding hole 1024.

[0085] When the linkage locking assembly 102 is in the unlocked state, in the initial stage, the locking wheel 1022 can move synchronously with the lock block 1021 close to the limiting protrusion 170 under the drive of the limiting member 210. Subsequently, when the locking wheel 1022 moves to a position in contact with the limiting protrusion 170, the lock block 1021 can continue to move in the original direction, while the locking wheel 1022 cannot move with the lock block 1021. At this time, the second elastic member 1028 is compressed. During this process, the second locking surface 1026 loses the function of pressing the locking wheel 1022 against the locking rope 101, and the locking wheel 1022 can be separated from the locking rope 101, so that the second end 1012 of the locking rope 101 can be smoothly pulled out. The second end 1012 of the locking rope 101 can be pulled out from the locking groove 1027, thus leaving the lock block 1021, and the tag assembly 001 can be removed from items such as clothing.

[0086] It should be understood that the second elastic member 1028 can be a spring, and both ends of the second elastic member 1028 can be fixed to the hole wall of the lock hole 1023 and the locking wheel 1022 by bonding. Obviously, in other embodiments, the second elastic member 1028 can also be directly clamped between the lock hole 1023 and the locking wheel 1022, and both ends of the second elastic member 1028 always remain in contact with the hole wall of the lock hole 1023 and the locking wheel 1022.

[0087] Please refer to Figures 13 - 15 , this embodiment also provides a bottle cap assembly 002, which includes a screw cap 201, an installation cylinder 202 and the above-mentioned password lock. The bottle cap assembly 002 can be a bottle cap assembly 002 for wine bottles, a bottle cap assembly 002 for cosmetics, etc.

[0088] Optionally, an avoidance notch 2011 is provided on the screw cap 201, and a clamping groove 2021 is provided on the mounting cylinder 202. The mounting cylinder 202 is used for sleeving outside the bottle mouth. The screw cap 201 is threadedly connected to the mounting cylinder 202. For example, the screw cap 201 has an internal thread, and the mounting cylinder 202 is sleeved at the bottle mouth and is provided with an external thread. When the screw cap 201 is screwed onto the mounting cylinder 202, the screw cap 201 closes the barrel opening of the mounting cylinder 202, that is, closes the bottle mouth of the bottle body. When the bottle mouth needs to be opened, the screw cap 201 needs to be rotated to unscrew it from the mounting cylinder 202, and the password lock can lock the screw cap 201 on the mounting cylinder 202 when in the locked state, so that it cannot rotate relative to the mounting cylinder 202. Please refer to Figure 14 , wherein the arrow direction indicates the direction of movement of the latch 203 relative to the screw cap 201 and the mounting cylinder 202 after unlocking. When the password lock is in the locked state, the screw cap 201 cannot rotate relative to the mounting cylinder 202. Specifically, the lock case 100 is connected to the screw cap 201, and a latch 203 is provided on the limiting member 210. Please refer to Figure 15 , when the limiting member 210 is in the first position, the latch 203 is embedded in the avoidance notch 2011 and separated from the clamping groove 2021, that is, after the password lock is unlocked, the latch 203 is not clamped in the clamping groove 2021. At this time, the screw cap 201 and the mounting cylinder 202 are not circumferentially limited by the latch 203, and the screw cap 201 can rotate relative to the mounting cylinder 202. Please refer to Figure 14 , correspondingly, when the limiting member 210 is in the second position, at this time, the limiting member 210 is in the locked state, the latch 203 is clamped with the clamping groove 2021, and the rotation of the screw cap 201 relative to the mounting cylinder 202 is restricted. The screw cap 201 cannot rotate relative to the mounting cylinder 202 to open. At this time, the user needs to obtain the password to open the password lock, so as to perform the bottle opening action.

[0089] Optionally, both the first half shell 110 and the second half shell 120 of the lock case 100 are circular structures, and the second half shell 120 is sleeved outside the screw cap 201. The second half shell 120 and the screw cap 201 are relatively fixed in the circumferential direction of the screw cap 201. For example, the second half shell 120 and the screw cap 201 can be matched through a concave-convex structure (not shown in the figure), so as to transfer the torque to the screw cap 201 by rotating the second half shell 120.

[0090] In addition, the limiting member 210 can be set to be integrally formed with the latch 203, that is, the limiting member 210 and the latch 203 are set as an integral structure, which has high structural strength, is not easily damaged, and has a long service life.

[0091] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
