Description

Technical Field

[0001] This technical solution relates to the field of anti-theft devices for goods, specifically a convenient anti-theft bottle buckle. Background Technology

[0002] In supermarkets and other retail establishments with self-service sales models, alcoholic beverages are frequently stolen due to their high price, especially high-end liquors, which cause significant economic losses to the stores.

[0003] To prevent the theft of alcoholic beverages, electronic anti-theft devices with steel ropes and strong magnetic locks are commonly used in the market as anti-theft tags for wine bottles in shopping malls. For example, Chinese patent CN202420232752.X discloses a net bag tag for anti-theft of wine bottles. Such tags can play a certain role in preventing theft of bottled wine. Through electronic sensing and other methods, an alarm can be triggered when the goods are taken out of the store without normal payment, thereby preventing the bottled wine from being stolen in its entirety to a large extent.

[0004] However, the existing anti-theft devices have obvious limitations. They cannot prevent thieves from opening bottles and drinking directly inside the mall. Thieves can open bottles and drink without the attention of mall staff, causing losses to the mall. Utility Model Content

[0005] The purpose of this technical solution is to provide a convenient anti-theft bottle lock. The lock cylinder is fitted onto the bottle mouth to cover it, and the driving part of the outer shell causes the locking tongue to abut against the side wall of the bottle mouth and work with the locking device to lock the bottle mouth, thereby improving the problem of existing alcoholic beverages being easily stolen and consumed.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A convenient anti-theft bottle buckle, comprising:

[0008] The outer casing has a drive unit located on its inner side;

[0009] A lock cylinder base is slidably disposed within the housing, and the lock cylinder base is provided with a receiving groove for accommodating the bottle mouth portion;

[0010] At least one latch is slidably disposed on the lock cylinder seat, and the latch can extend into the receiving groove;

[0011] A locking device is mounted on the housing and is movably engaged with the lock cylinder seat. The locking device is used to restrict the relative movement between the housing and the lock cylinder seat.

[0012] In use, after placing the bottle opening into the receiving groove, the outer shell is pressed to move it on the lock cylinder seat, causing the driving part to drive the locking tongue to move toward the receiving groove, so that the front end of the locking tongue extends into the receiving groove and abuts against the lower end of the protruding edge of the outer wall of the bottle opening, thereby locking the bottle opening.

[0013] Preferably, the lower front side of the drive unit has a guide surface one, and the upper rear side of the locking tongue has a guide surface two;

[0014] When the drive unit abuts against the bolt, the first guide surface slides on the second guide surface, causing the bolt to move on the lock cylinder seat toward the receiving groove and extend into the receiving groove.

[0015] Preferably, the lock cylinder seat is provided with at least one sliding groove in the circumferential direction, the lock tongue is slidably disposed in the sliding groove, and a through hole is provided on the side wall of the receiving groove, the through hole connecting the sliding groove and the receiving groove;

[0016] When the driving unit drives the locking tongue to slide in the sliding groove, the locking tongue extends into the receiving groove through the through hole.

[0017] Preferably, the sliding groove is provided with a mounting groove, the latch is provided with a mounting protrusion, the mounting protrusion is inserted into the mounting groove, and an elastic element is provided between the mounting groove and the mounting protrusion, the elastic element causing the latch to have a tendency to move away from the receiving groove.

[0018] Preferably, the side end of the latch is provided with a limiting protrusion, and the side wall of the sliding groove is provided with a limiting groove corresponding to the limiting protrusion, and the limiting protrusion is slidably placed in the limiting groove.

[0019] Preferably, the outer wall of the lock cylinder seat has a plurality of teeth I, and the locking device is provided with at least one tooth II. The teeth I and the teeth II engage to restrict the movement of the outer shell on the lock cylinder seat along the axial direction of the lock cylinder seat.

[0020] Preferably, the tooth is inclined in a direction away from the upper end of the lock cylinder seat, such that the upper sidewall of the tooth forms a guide surface and the lower sidewall of the tooth forms a locking surface.

[0021] The second tooth is inclined toward the upper end of the outer shell, such that the upper sidewall of the second tooth forms a locking surface, and the lower sidewall of the second tooth forms a guiding surface.

[0022] The drive unit moves toward the bolt by sliding against the guide surface one and abutting against the guide surface two; the movement of the drive unit away from the bolt is restricted by the locking surface one and the locking surface two abutting against each other.

[0023] Preferably, the side wall of the housing is provided with a mounting hole, which connects the interior of the housing with the outside.

[0024] The locking device includes:

[0025] A fastener is installed in the mounting hole;

[0026] A locking element having ferromagnetic properties, the locking element being slidably disposed within the mounting hole, and the front end of the locking element having at least one of the teeth;

[0027] The second elastic element is installed between the fixing element and the locking element, so that the locking element can move toward the lock cylinder seat, thereby realizing the engagement of the second tooth with the first tooth.

[0028] Preferably, an elastic element three is provided between the outer shell and the lock cylinder seat, and the elastic element three causes the driving part to tend to move in a direction away from the lock tongue.

[0029] Preferably, the inner sidewall of the outer casing is provided with at least one rotation limiting part in the circumferential direction, and the outer side of the lock cylinder seat is provided with a rotation limiting groove corresponding to the rotation limiting part. The rotation limiting part is inserted into the rotation limiting groove to restrict the rotation of the outer casing on the lock cylinder seat.

[0030] Preferably, the lock cylinder base is provided with a plurality of lock tongues in the circumferential direction, and the inner side of the housing is provided with a plurality of driving parts corresponding to the lock tongues;

[0031] When the outer shell is pressed, each drive unit drives the corresponding locking tongue to move synchronously, so that several locking tongues are linked together, thereby enabling the front end of each locking tongue to simultaneously extend into the receiving groove and lock the bottle mouth and the lower end of the protrusion.

[0032] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0033] 1. This technical solution covers the bottle opening by fitting a lock cylinder seat onto the bottle opening. The drive unit of the outer casing moves the locking tongue to abut the side wall of the bottle opening, and together with the locking device, locks the bottle opening, preventing the entire bottle from being stolen and also preventing thieves from opening the bottle and drinking directly in the store. At the same time, the user can lock the locking tongue to the side wall of the bottle opening by pressing the outer casing with one hand, which is convenient to use. Moreover, the locking tongue can be adjusted to fit different diameter bottles by moving a certain distance, making it highly adaptable.

[0034] 2. This technical solution, through the cooperation of guide surface one and guide surface two, enables the outer shell to be driven to move towards the lower end of the lock cylinder seat by pressing the outer shell, so that the drive unit drives the lock tongue to abut against the side wall of the bottle mouth for locking operation, which is simple and convenient to operate.

[0035] 3. This technical solution uses a locking device to lock or unlock the outer shell and the lock cylinder seat. When unlocking, the outer shell moves to a set position on the lock cylinder seat under the action of the elastic element three. At this time, the drive unit does not restrict the movement of the bolt, and the elastic element one resets the bolt to unlock. The operation is convenient and the unlocking is quick.

[0050] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-9 .

[0051] Combination Figure 1 and Figure 2 A convenient anti-theft bottle buckle, comprising:

[0052] The outer casing 1 has a drive unit 11 disposed on its inner side;

[0053] The lock cylinder seat 2 is slidably disposed inside the outer shell 1, and the lock cylinder seat 2 is provided with a receiving groove 21. The receiving groove 21 is used to receive the bottle mouth 51 part of the bottle 5. That is, by fitting the outer shell 1 and the lock cylinder seat 2 onto the bottle mouth 51 of the wine bottle to be burglarized, this part of the bottle mouth 51 of the wine product is placed in the receiving groove 21.

[0054] At least one latch 3 is slidably disposed on the lock cylinder seat 2, and the front end of the latch 3 can extend into the receiving groove 21. A drive unit 11 corresponds to the latch 3, allowing the drive unit 11 to slide against the latch 3; and

[0055] Locking device 4 is mounted on the outer casing 1 and is movably engaged with the lock cylinder seat 2. That is, locking device 4 can engage or disengage from the lock cylinder seat 2. Locking device 4 restricts the movement of the outer casing 1 on the lock cylinder seat 2, thus restricting the relative movement between the outer casing 1 and the lock cylinder seat 2. When locking device 4 is in the locked state, it engages with the lock cylinder seat 2, restricting the movement of the outer casing 1 on the lock cylinder seat 2. This ensures that the drive unit 11 restricts the movement of the bolt 3, preventing the drive unit 11 from disengaging from the bolt 3 and causing the bolt 3 to move and unlock. When locking device 4 is in the unlocked state, the outer casing 1 can move on the lock cylinder seat 2, causing the drive unit 11 to separate from the bolt 3. That is, the drive unit 11 does not restrict the movement of the bolt 3, allowing the bolt 3 to move and unlock.

[0056] When the anti-theft bottle buckle of this design is installed on the bottle mouth 51 of the bottle 5 of the liquor product, after the bottle mouth 51 is placed into the receiving groove 21, the locking device 4 is first in the unlocked state. Then, by pressing the outer shell 1 with external force, it moves on the lock cylinder seat 2 towards the direction closer to the bottle 5, so that the driving part 11 moves towards the direction closer to the locking tongue 3 and drives the locking tongue 3 to move on the lock cylinder seat 2 towards the receiving groove 21, so that the front end of the locking tongue 3 extends into the receiving groove 21, so that the locking tongue 3 abuts against the side wall of the bottle mouth 51 of the bottle 5 and the locking tongue 3 abuts against the lower end of the protrusion 52 of the outer wall of the bottle 5, thereby locking the bottle mouth 51 and locking the locking device 4 in the locked state, thus realizing the locking operation.

[0057] The drive unit 11 is formed on the inner side wall of the housing 1, and the number of drive units 11 corresponds to the number of locking tongues 3.

[0058] In order to improve the locking stability between the locking tongue 3 and the side wall of the bottle mouth 51, this technical solution adopts at least three locking tongues 3 circumferentially distributed on the lock cylinder seat 2, and the number of driving parts 11 is also at least three.

[0059] When a number of locking tongues 3 are provided, the number of driving units 11 can correspond one-to-one with the number of locking tongues 3. When the outer shell 1 is pressed to make the locking tongue 3 extend into the receiving groove 21 for locking, each driving unit 11 drives the corresponding locking tongue 3 to move synchronously, so that the number of locking tongues 3 are linked together, thereby ensuring that the front end of each locking tongue 3 can extend into the receiving groove 21 at the same time and lock the bottle mouth 51 and the lower end of the protrusion 52.

[0060] The space between several locking tongues 3 or the space between a locking tongue 3 and the side wall opposite to the receiving groove 21 is the range for locking the bottle 5, i.e., the locking space. By adjusting the downward movement distance of the outer shell 1, i.e. changing the movement distance of the drive unit 11, the movement distance of the locking tongue 3 on the sliding groove 22 is changed, thereby changing the length of the front end of the locking tongue 3 extending into the receiving groove 21, which in turn changes the locking space between the locking tongues 3, thereby adapting to bottle mouths 51 of different diameters and improving adaptability.

[0061] like Figure 7 and Figure 9 The front end of the locking tongue 3 has a locking protrusion 35, which is an arc-shaped structure. The front end of the locking protrusion 35 can be attached to the side wall of the bottle mouth 51, and the locking protrusion 35 can abut against the lower end of the protrusion 52 on the outer side wall of the bottle mouth 51 to prevent the bottle mouth 51 from leaving the receiving groove 21.

[0062] Combination Figure 2The lower front side of the drive unit 11 has a guide surface 111, and the upper rear side of the locking tongue 3 has a guide surface 31. When the drive unit 11 abuts against the locking tongue 3, it slides on the guide surface 31 through the guide surface 111, so that the locking tongue 3 moves on the lock cylinder seat 2 toward the direction close to the receiving groove 21, so that the front end of the locking tongue 3 extends into the receiving groove 21 and abuts against the side wall of the bottle mouth.

[0063] When the locking tongue 3 is in the unlocked position, that is, in the initial position, the position of the lowest point of the guide surface 111 projected onto the plane perpendicular to the moving direction of the outer shell 1 is behind the position of the highest point of the guide surface 31 projected onto the plane perpendicular to the moving direction of the outer shell 1, ensuring that the guide surface 111 can slide on the guide surface 31.

[0064] When the locking tongue 3 is in the locked state, that is, when the locking tongue 3 abuts against the side wall of the bottle mouth 51, the position of the uppermost point of the guide surface 111 projected onto the plane perpendicular to the moving direction of the outer shell 1 is the front side of the position of the lowermost point of the guide surface 31 projected onto the plane perpendicular to the moving direction of the outer shell 1, ensuring that the guide surface 111 can slide on the guide surface 31.

[0065] Combination Figures 4-7 The outer shell 1 and the lock cylinder seat 2 are similar cylindrical structures, which makes the receiving groove 21 cylindrical, so that the receiving groove 21 can be adapted to the bottle mouth 51. At the same time, the lock tongue 3 adopts a fan-shaped structure, which makes the left and right directions of the guide surface 2 31 arc-shaped, and the left and right directions of the corresponding guide surface 111 are arc-shaped.

[0066] Combination Figure 3 and Figure 6 The lock cylinder seat 2 is provided with at least one sliding groove 22 in the circumferential direction. The sliding groove 22 is distributed in the circumferential direction on the outside of the receiving groove 21. The lock tongue 3 is slidably disposed in the sliding groove 22. A through hole 23 is provided on the side wall of the receiving groove 21, and the through hole 23 connects the sliding groove 22 and the receiving groove 21.

[0067] When the driving unit 11 drives the locking tongue 3 to slide in the sliding groove 22, the front end of the locking tongue 3 extends into the receiving groove 21 through the through hole 23 to abut against the side wall of the bottle mouth 51. When the driving unit 11 disengages from the locking tongue 3, the locking tongue 3 can retract into the sliding groove 22, so that the front end of the locking tongue 3 disengages from the side wall of the bottle mouth 51, and the locking tongue 3 disengages from the lower end of the protrusion 52.

[0068] Combination Figures 2-7At least one mounting groove 24 is provided on the bottom or side wall of the sliding groove 22, and the locking tongue 3 is provided with a mounting protrusion 32 corresponding to the mounting groove 24. The technical solution is to provide a mounting groove 24 at the bottom of the sliding groove 22 and a mounting protrusion 32 at the bottom of the locking tongue 3. When the locking tongue 3 is slidably placed in the sliding groove 22, the mounting protrusion 32 is inserted into the mounting groove 24, and an elastic element 33 is provided between the mounting groove 24 and the mounting protrusion 32. The elastic element 33 is a spring or a disc spring. The front end of the elastic element 33 abuts against the front side wall of the mounting groove 24, and the rear end of the elastic element 33 abuts against the front end face of the mounting protrusion 32. The elastic element 33 makes the locking tongue 3 tend to move away from the receiving groove 21 to achieve reset. That is, the elastic deformation of the elastic element 33 makes the front end of the locking tongue 3 separate from the side wall of the bottle mouth 51, thereby realizing the movement and unlocking of the locking tongue 3.

[0069] The drive unit 11 is slidably disposed in the sliding groove 22, and the drive unit 11 slides up and down in the sliding groove 22, while the locking tongue 3 slides back and forth in the sliding groove 22. The sliding direction of the drive unit 11 and the locking tongue 3 is perpendicular.

[0070] Combination Figure 6 and Figure 7 To prevent the latch 3 from sliding up and down within the sliding groove 22 and to ensure the accurate and stable forward and backward sliding direction of the latch 3 within the sliding groove 22, a limiting protrusion 34 is provided on the side end of the latch 3. A limiting groove 221 corresponding to the limiting protrusion 34 is provided on the side wall of the sliding groove 22. The limiting protrusion 34 is slidably placed within the limiting groove 221. The cooperation between the limiting protrusion 34 and the limiting groove 221 restricts the latch 3 from sliding up and down within the sliding groove 22, while guiding the latch 3 to slide forward and backward within the sliding groove 22, so that the latch 3 approaches or moves away from the center of the receiving groove 21.

[0071] Combination Figure 2 and Figure 3 The outer wall of the lock cylinder seat 2 has several teeth 25, which are distributed along the axial direction of the lock cylinder seat 2. The locking device 4 is provided with at least one tooth 44. The teeth 25 and the tooth 44 are convex tooth structures. The teeth 25 and the tooth 44 are engaged to restrict the movement of the outer shell 1 on the lock cylinder seat 2 along the axial direction of the lock cylinder seat 2. When the anti-theft bottle buckle of this design is installed at the bottle mouth 51 of the bottle 5, the locking device 4 needs to be in the unlocked state first. Then, the outer shell 1 is pressed by external force to move on the lock cylinder seat 2 toward the direction of the bottle 5 to lock it.

[0072] like Figure 3In order to improve the ease of installation of the anti-theft bottle buckle, that is, without unlocking the locking device 4 first, the locking operation can be achieved by pressing the outer shell 1, so that the tooth 25 is tilted away from the upper end of the lock cylinder seat 2, so that the upper side wall of the tooth 25 forms the guide surface 251 and the lower side wall of the tooth 25 forms the locking surface 252.

[0073] The second tooth 44 is inclined toward the upper end of the outer shell 1, so that the upper sidewall of the second tooth 44 forms a locking surface 441 and the lower sidewall of the second tooth 44 forms a guide surface 442.

[0074] When installing the anti-theft bottle buckle onto the bottle neck, there is no need to unlock the locking device 4. Simply press the outer shell 1, and guide surface 1 251 slides against guide surface 2 442, causing the outer shell 1 to move on the lock cylinder seat 2 toward the direction closer to the bottle 5. This causes the drive unit 11 to move toward the direction closer to the lock tongue 3 and drive the lock tongue 3 to move and abut against the side wall of the bottle neck to achieve locking. Locking can be achieved by pressing with one hand, which improves the convenience of installation, increases efficiency, and saves time and manpower.

[0075] By abutting the locking surface 252 and the locking surface 441, the movement of the drive unit 11 away from the lock tongue 3 can be restricted, that is, the movement of the outer shell 1 away from the bottle 5 on the lock cylinder seat 2 can be restricted, thus preventing the lock tongue 3 from disengaging from the side wall of the bottle mouth and unlocking.

[0076] Combination Figures 2-4 The side wall of the outer shell 1 is formed with a protrusion 15, and a mounting hole 12 is provided in the protrusion 15. The mounting hole 12 connects the inside of the outer shell 1 with the outside. The locking device 4 is installed in the mounting hole 12 and can be inserted into the outer shell 1 through the mounting hole 12 to engage and lock with the lock cylinder seat 2.

[0077] Locking device 4 includes:

[0078] The fastener 41 is glued or integrally molded and installed in the mounting hole 12;

[0079] The locking member 42 is ferromagnetic, and is slidably disposed in the mounting hole 12, and the front end of the locking member 42 has at least one tooth 44.

[0080] The second elastic element 43 is a spring. The second elastic element 43 is installed between the fixed element 41 and the locking element 42, so that the locking element 42 can move towards the lock cylinder seat 2, so that the second tooth 44 and the first tooth 25 can be engaged. Through the elastic deformation of the second elastic element 43, the second tooth 44 and the first tooth 25 of the locking element 42 can remain in contact, so that when the outer shell 1 is pressed down, the second tooth 44 and the first tooth 25 can be automatically engaged, that is, in a locked state.

[0081] The locking element 42 is ferromagnetic, meaning it is made of magnetic materials such as iron, cobalt, nickel, or their alloys. The locking element 42 only has the characteristic of being attracted by magnetic objects; it does not possess continuous magnetism itself and cannot actively attract other magnetic materials. It can only be attracted by magnetic objects such as magnets. For example, when a magnet approaches, the locking element 42 will be attracted by it. The locking element 42 itself cannot attract other iron, cobalt, nickel, or similar objects. This ensures that the locking element 42 can only be unlocked when the merchant uses a specific magnet to attract it, preventing it from being directly unlocked by the metal shelf and thus improving the security of the locking device 4.

[0082] Mounting hole 12 includes a fastener mounting hole and a locking mounting hole that are interconnected. The diameter of the fastener mounting hole is larger than that of the locking mounting hole. The fastener 41 is integrally formed or glued to the fastener mounting hole. The front end of the fastener 41 has a relief groove 411 for the rear end of the locking member 42 to slide into. The lower end of the locking member 42 has a limiting part 421, and the inner wall of the locking mounting hole has a limiting part 121. The limiting part 421 moves against the limiting part 121 to prevent the locking member 42 from disengaging from the front end of the mounting hole 12.

[0083] like Figure 2 An elastic element 313 is provided between the outer shell 1 and the lock cylinder seat 2. The elastic element 313 is a spring. The elastic element 313 causes the driving part 11 to tend to move away from the lock tongue 3. When the locking device 4 is in the unlocked state, the elastic element 313 causes the outer shell 1 and the lock cylinder seat 2 to move away from each other, so that the driving part 11 does not restrict the movement of the lock tongue 3. In conjunction with the elastic element 133, the movement and reset of the lock tongue 3 are realized, thereby realizing that the lock tongue 3 does not lock the bottle mouth and realizes unlocking.

[0084] Combination Figure 5 and Figure 6 The inner sidewall of the outer shell 1 is provided with at least one rotation limiting part 14 in the circumferential direction. The rotation limiting part 14 is a rotation limiting protrusion provided along the axis of the outer shell 1. The outer side of the lock cylinder seat 2 is provided with a rotation limiting groove 26 corresponding to the rotation limiting part 14. The rotation limiting part 14 is inserted into the rotation limiting groove 26 to limit the rotation of the outer shell 1 on the lock cylinder seat 2. At the same time, the sliding of the rotation limiting part 14 and the rotation limiting groove 26 can guide the movement direction of the outer shell 1 on the lock cylinder seat 2. The cooperation between the rotation limiting part 14 and the rotation limiting groove 26 can ensure the stability of the engagement between the first tooth 25 and the second tooth 44, and prevent the outer shell 1 from rotating and causing the first tooth 25 and the second tooth 44 to disengage.

[0085] Combination Figure 2 and Figure 4 An anti-detachment ring 18 is glued to the lower end of the outer casing 1. The anti-detachment ring 18 moves against the lower edge of the lock cylinder seat 2 to prevent the lock cylinder seat 2 from detaching from the outer casing 1.

[0086] The above solution can solve the problem of alcoholic beverages being opened and consumed without permission. In order to prevent theft of alcoholic beverages, this design also includes an anti-theft mechanism. The anti-theft mechanism is set on the outer shell 1. Specifically, an installation cavity 16 is set on the upper end of the outer shell 1. A cover 17 is provided on the installation cavity 16. The cover 17 is fixed by adhesive or integral injection molding. An anti-theft mechanism is set inside the installation cavity 16. The anti-theft mechanism is a sensing element. The sensing element can cooperate with the sensing device at the entrance of the mall. When the bottle is taken out of the mall entrance, the sensing device at the mall entrance will detect the sensing element and sound an alarm.

[0087] The sensing element may specifically be a coil antenna used in a radio frequency (RF) system, a magnetostrictive coil and pickup coil used in an acousto-magnetic (AM) system, a low-frequency coil equipped in an electromagnetic (EM) system, or a reader antenna used in an RFID system.

[0088] In addition, the anti-theft mechanism can also use a single anti-theft rope or a double anti-theft rope and a sensing element. When using an anti-theft rope, one end of the anti-theft rope is fixed to the connecting ear hole on the outer shell 1 by an integral molding or padlock, and the other end of the anti-theft rope is fixed to the shelf by a padlock, thereby limiting the movement range of the bottles of alcoholic beverages.
