Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a locking device for a wine bottle packaging box. Background Technology

[0002] Locking devices are mechanical components that connect, fix, or lock objects through fastening, clamping, or other methods. Locking devices used in wine bottle packaging boxes are mainly used to firmly fix wine bottles to prevent them from shaking and breaking during transportation, improve the sealing of the packaging to protect the quality of the wine, enhance the structural stability of the box, and increase the sense of ceremony when opening the box, thereby improving the overall grade of the product and the user experience.

[0003] A search revealed Chinese patent (CN220333494U), which includes a fastening element and a locking element. The fastening element comprises a first connecting plate and a fastening frame sleeve, with the fastening frame sleeve connected to one side of the first connecting plate. The locking element comprises a connecting block, a second connecting plate, and a back buckle. The second connecting plate and the back buckle extend from the same side of the connecting block at intervals, forming a clamping groove between the second connecting plate and the back buckle. When the fastening element is engaged with the locking element, the fastening frame sleeve is embedded in the clamping groove and engages with the back buckle. The wine bottle packaging box includes a box body and an L-shaped cover. The L-shaped cover includes a long plate portion for sealing the opening of the box body and a short plate portion for fastening. The short plate portion is provided with a fastening element, and the box body is provided with a locking element. This application uses the fastening frame sleeve and the back buckle to engage with each other, with the fastening frame sleeve embedded in the clamping groove and the back buckle hooking onto the fastening frame sleeve, making it impossible for the wine bottle packaging box to be disassembled and resealed.

[0004] When the above-mentioned patent is used, it proposes to use the assembly between fasteners and locking fasteners. The fastening frame is embedded in the clamping groove and connected with the inverted buckle buckle, which improves the sealing and security of the wine bottle packaging box. Although it needs to ensure the anti-counterfeiting effect, its one-time destructive structural design and inefficient use of resources violate the green development orientation of recycling and cannot reflect the sense of opening ceremony, nor does it improve the overall grade of the product and the user experience.

[0005] To address this, we propose a locking device for wine bottle packaging boxes that features magnetic positioning and rotational feedback design. Utility Model Content

[0006] One of the technical problems this application aims to solve is that its one-time opening and closing structure cannot be reused, lacks a sense of ritual in opening, and does not enhance the overall quality of the product or the user experience.

[0007] To solve the above-mentioned technical problems, this application provides a locking device for a wine bottle packaging box, including two box covers. The top right side of the box cover is provided with a right and left semi-circular groove, the bottom inner side of the left semi-circular groove is provided with a fixing semi-circular block, and the top of the fixing semi-circular block is provided with a rotating component. The top left side of the other box cover is provided with a right semi-circular groove, the bottom inner side of the right semi-circular groove is provided with a mounting block, and the interior of the mounting block is provided with a locking component.

[0008] In some embodiments, the rotating assembly includes a limiting circular plate, the top of which is disposed on the top of the fixed semicircular block, and a screw cap is rotatably connected to the outside of the limiting circular plate.

[0009] In some embodiments, an anti-slip ring is provided on the outside of the screw cap, and a pointing protrusion is provided on the top of the anti-slip ring.

[0010] In some embodiments, the locking assembly includes three return springs, the outer surfaces of which are disposed in the inner grooves of the mounting block, and the ends of the return springs are provided with locking tongues, the outer surfaces of which are slidably connected to the interior of the mounting block.

[0011] In some embodiments, a magnetic block is provided on the top of the mounting block, and a magnetic seat is provided on the bottom right side of the limiting circular plate. The outside of the magnetic block is detachably connected to the inside of the magnetic seat.

[0012] In some embodiments, the inner side of the cap is provided with a plurality of locking grooves, and the outer side of the locking tongue is slidably connected to the inner side of the locking grooves.

[0013] In some embodiments, the bottom of the cap has three opening slots, and the outer side of the latch is slidably connected to the inner side of the opening slots.

[0014] This utility model has at least the following beneficial effects: 1. With the cooperation of anti-slip ring and directional protrusion, users can quickly locate the unlocking direction and rotate the cover with ease. The multiple lock groove design produces a clicking sound during rotation, providing clear operation feedback. The dual effect of the inclined guide structure of the opening groove and the magnetic attraction makes the lock tongue disengage from the cover more smoothly. It can be opened without complicated operation, significantly improving the user's convenience and interactive experience.

[0015] 2. The precise magnetic attraction between the magnetic block and the magnetic base enables the initial positioning of the two box lids, preventing misalignment of the locking components. Three return springs drive the locking tongue to embed into the locking groove to form a stable mechanical lock, which can resist vibration and collision during transportation and handling, prevent the packaging box from being opened accidentally, effectively ensure the safety of the wine bottle in the circulation process, and reduce the risk of breakage.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a locking device for a wine bottle packaging box, including two symmetrically arranged and interlocking box lids 1. The top right side of the box lid 1 is provided with a right and left semi-circular groove 2. The left semi-circular groove 2 has an inwardly concave arc structure to accommodate the locking component. The bottom inner side of the left semi-circular groove 2 is provided with a fixing semi-circular block 4. The fixing semi-circular block 4 fits against the inner wall of the left semi-circular groove 2 and plays a supporting and positioning role. The top of the fixing semi-circular block 4 is provided with a rotating component 5. The rotating component 5 is used to drive the locking device to unlock. The top left side of the other box lid 1 is provided with a right semi-circular groove 3. The right semi-circular groove 3 matches the size of the left semi-circular groove 2 and forms a complete circular groove after being interlocked. The bottom inner side of the right semi-circular groove 3 is provided with an installation block 6. The installation block 6 has a cubic structure for housing a locking component 7. The installation block 6 has a locking component 7 inside. The locking component 7 is used to lock and fix the two box lids 1. The rotating assembly 5 includes a limiting circular plate 51, which is a circular flat plate and serves to limit the screw cap 52. The top of the limiting circular plate 51 is set on the top of the fixed semicircular block 4 and remains stationary. The screw cap 52 is rotatably connected to the outside of the limiting circular plate 51. The screw cap 52 is a ring structure and can move in a circle around the axis of the limiting circular plate 51. An anti-slip ring 53 is provided on the outside of the screw cap 52. The surface of the anti-slip ring 53 is provided with concave and convex textures to increase the friction of the hand and prevent slipping. The top of the anti-slip ring 53 is provided with a pointing protrusion 54, which is a hemispherical protrusion used to indicate the unlocking rotation direction. The pointing protrusion 54 is used to mark the initial rotation position and unlocking direction of the screw cap 52, improving the ease of operation.

[0020] Example 2: Please refer to Figures 3-5 The locking assembly 7 includes three return springs 71, which are evenly distributed in a circle to ensure that the locking tongue 72 is subjected to balanced force. The three return springs 71 are externally disposed in the internal groove of the mounting block 6. The size of the internal groove matches the return springs 71 and restricts the lateral displacement of the springs. The end of the return springs 71 is provided with a locking tongue 72. The locking tongue 72 has a wedge-shaped structure and can extend and retract under the action of spring force. The external parts of the three locking tongues 72 are slidably connected to the inside of the mounting block 6. The mounting block 6 is provided with a sliding channel that matches the locking tongues 72. The top of the mounting block 6 is provided with a magnetic block 76, which is a cylindrical strong magnet used for initial positioning. The bottom right side of the limiting circular plate 51 is provided with a magnetic seat 75, which is a concave circular groove and magnetically attracted to the magnetic block 76. The outside of the magnetic block 76 is detachably connected to the inside of the magnetic seat 75. The magnetic attraction force enables quick docking and separation, and the magnetic attraction force enables initial positioning, ensuring that the left semicircular groove 2 and the right semicircular groove 3 of the two box covers 1 are accurately docked, avoiding locking failure caused by relative displacement of the locking components. The inner side of the cap 52 is provided with multiple locking grooves 73, which are evenly distributed in a circle and are used to engage with the latch 72. The design of the multiple locking grooves 73 makes the cap 52 produce a clicking sound during rotation, providing clear operational feedback. The latch 72 is externally slidably connected to the inner side of the locking groove 73. The depth of the locking groove 73 matches the extension length of the latch 72 to ensure a stable lock. The bottom of the cap 52 has three opening grooves 74, which correspond one-to-one with the latch 72 and have an inclined guide structure. The outside of the latch 72 is externally slidably connected to the inside of the opening grooves 74. When the left side cover 1 is opened, the opening grooves 74 at the bottom of the cap 52 slide out of the latch 72, realizing the opening of the wine bottle packaging box.

[0021] Based on the above embodiments, the following is the complete working principle of the above embodiments: The magnetic block 76 installed on the top of the mounting block 6 at the bottom of the inner side of the right semicircular groove 3 forms a magnetic attraction with the magnetic seat 75 on the right side of the bottom of the limiting circular plate 51 in the rotating assembly 5 at the top of the fixed semicircular block 4 at the bottom of the inner side of the left semicircular groove 2. The magnetic block 76 is embedded inside the magnetic seat 75 and achieves initial positioning through magnetic attraction, ensuring that the left semicircular groove 2 and the right semicircular groove 3 of the two box covers 1 are accurately aligned, avoiding locking failure caused by relative displacement of the locking components. In the locking assembly 7, three return springs Both 71 are in a naturally extended state. Their elastic force acts on the locking tongue 72 connected at the end, pushing the locking tongue 72 to extend outward along the sliding channel inside the mounting block 6. At this time, the swivel cover 52 in the rotating assembly 5 is in the initial locked position. The locking groove 73 opened on the inner side of the swivel cover 52 is precisely aligned with the extended end of the locking tongue 72. Under the elastic force of the return spring 71, the locking tongue 72 is embedded in the inner side of the locking groove 73, forming a mechanical locking structure, which restricts the rotational freedom of the swivel cover 52, thereby achieving stable locking of the two box covers 1 and preventing the packaging box from being accidentally opened during transportation and handling. When the bottle packaging box needs to be opened, the locking component 7 is unlocked by operating the rotating component 5. The user's hand acts on the anti-slip ring 53 on the outside of the cap 52, and rotates the cap 52 in the unlocking direction according to the direction indicated by the protrusion 54. The cap 52 rotates circumferentially around the axis of the limiting circular plate 51, which is fixed to the top of the fixed semicircular block 4 and remains stationary. As the cap 52 rotates, the locking groove 73 on its inner side rotates synchronously with the cap 52, gradually disengaging from the engagement position with the locking tongue 72. The multiple locking grooves 73 design produce a clicking sound during rotation. When the cap 52 rotates to the unlocking angle, the opening at its bottom... When the opening slot 74 is rotated to the position corresponding to the locking tongue 72, the locking tongue 72 disengages from the locking slot 73 and embeds into the inner side of the opening slot 74 due to the inclined guide structure of the inner wall of the opening slot 74. At this time, the left box cover 1 is opened, and a separation tendency occurs relative to the right box cover 1. The magnetic attraction block 76 and the magnetic attraction base 75 produce relative displacement. The magnetic attraction force is insufficient to maintain the embedded state of the two. The user can apply a small separation force to make the magnetic attraction block 76 disengage from the magnetic attraction base 75. At the same time, the opening slot 74 at the bottom of the screw cap 52 slides out of the outside of the locking tongue 72, and the mechanical locking state of the locking component 7 is released, thereby separating the two box covers 1 to both sides and realizing the opening of the wine bottle packaging box.
