Description

Technical Field

[0001] This invention relates to the field of packaging box technology, and in particular to a lifting and rotating linkage packaging box. Background Technology

[0002] Gift packaging boxes are the core carriers used for gift storage, decoration and display. With the upgrading of consumption, users have put forward higher requirements for the sense of ritual, interactivity and display effect of gift packaging boxes.

[0003] Most existing gift packaging boxes are fixed structures with top and bottom lids or flip-tops, offering limited functionality and only basic storage without dynamic display effects or a sense of ceremony. Some gift packaging boxes with lifting functions mostly use manual pull-out and flip-top linkage to achieve lifting, which is cumbersome to operate and provides a poor opening and closing experience. A few packaging boxes with rotating lifting display functions rely on electric motors and other electric drives, which have limited battery life, circuit failure risks, high manufacturing costs, and insufficient reliability under long-term storage, making it difficult to meet users' needs for high-end, ceremonial gift packaging that can operate reliably without electricity. Summary of the Invention

[0004] This invention aims to at least solve the technical problems existing in the prior art. To this end, this invention proposes a lifting and rotating linkage packaging box that requires no electric drive throughout the entire process. It achieves a fully linked process through a purely mechanical structure, with a single press to close the lid and lock it, a second press to unlock and pop it up, and an automatic rotation to trigger the display when the lid is opened. It is easy to operate, highly reliable, and provides a strong sense of ceremony in the display.

[0005] According to some embodiments of the present invention, a lifting and rotating linkage packaging box includes a bottom box, a top cover, a lifting mechanism, and a spring-driven rotating mechanism. The lifting mechanism is disposed between the bottom box and the top cover, and includes a bottom plate, a first connecting plate, a second connecting plate, a top plate, and a scissor-type telescopic assembly. The bottom plate, the first connecting plate, the second connecting plate, and the top plate are sequentially connected to the scissor-type telescopic assembly from bottom to top. A locking rod is fixedly disposed on the top plate, and a locking seat is fixedly disposed on the first connecting plate. The locking rod and the locking seat cooperate to form a press-locking mechanism. A [missing information - likely a mechanism or method] is disposed between the first connecting plate and the bottom plate. A return spring is provided to drive the scissor-type telescopic assembly to unfold and spring up after the self-locking mechanism is unlocked. The upper cover is connected to the spring-driven rotating mechanism, which is connected to the top plate. The output end of the spring-driven rotating mechanism is provided with a rotating plate to drive the rotating plate to rotate relative to the top plate. The rotating plate is located inside the upper cover. The bottom of the rotating plate is provided with multiple anti-rotation protrusions, and anti-rotation grooves are formed between adjacent anti-rotation protrusions. The anti-rotation protrusions are distributed in a ring at intervals. A pin is provided on the second connecting plate, which is located below the anti-rotation protrusions. A decorative piece is provided at the edge of the upper cover.

It avoids the drawbacks of traditional electric packaging boxes, such as limited battery life, susceptibility to malfunctions, high cost, and poor long-term reliability. It can be used repeatedly for extended periods and is highly adaptable to various scenarios. Through a press-lock mechanism, a scissor-type telescopic component, and a return spring, simply pressing the top cover locks it in place, and pressing again unlocks it. No additional auxiliary components are needed, making the opening and closing process simple and convenient, enhancing the ritualistic feel of opening gifts. A pin linked to the scissor-type telescopic component works in conjunction with the anti-rotation slot of the rotating plate to achieve mechanical linkage between lifting and rotation limits.

[0028] like Figures 1-6 As shown in the figure, an embodiment of the present invention provides a lifting and rotating linkage packaging box.

[0029] A lifting and rotating linkage packaging box includes a base box 1, an upper cover 2, a lifting mechanism 3, and a spring-driven rotating mechanism 13. The lifting mechanism 3 is disposed between the base box 1 and the upper cover 2. The lifting mechanism 3 includes a base plate 4, a first connecting plate 5, a second connecting plate 6, a top plate 7, and a scissor-type telescopic assembly 8. The base plate 4, the first connecting plate 5, the second connecting plate 6, and the top plate 7 are sequentially connected to the scissor-type telescopic assembly 8 from bottom to top. A locking rod 9 is fixedly disposed on the top plate 7, and a locking seat 10 is fixedly disposed on the first connecting plate 5. The locking rod 9 and the locking seat 10 cooperate to form a press-locking mechanism. A return spring 12 is disposed between the first connecting plate 5 and the base plate 4. The spring 12 is used to drive the scissor-type telescopic assembly 8 to unfold and spring up after the self-locking mechanism is unlocked; the upper cover 2 is connected to the spring-rotating drive mechanism 13, the spring-rotating drive mechanism 13 is connected to the top plate 7, and the output end of the spring-rotating drive mechanism 13 is provided with a rotating plate, which is used to drive the rotating plate 45 to rotate relative to the top plate 7. The rotating plate 45 is located on the upper cover 2; the bottom of the rotating plate 45 is provided with a plurality of anti-rotation protrusions 14, and an anti-rotation groove 15 is formed between adjacent anti-rotation protrusions 14. The anti-rotation protrusions 14 are distributed in a ring at intervals. The second connecting plate 6 is provided with a pin 16, which is located below the anti-rotation protrusions 14. The edge of the upper cover 2 is provided with a decorative piece 17.

[0030] This invention requires no electricity throughout the entire process, achieving all functions through a purely mechanical structure. It avoids the drawbacks of electric packaging boxes, such as limited battery life, susceptibility to malfunctions, high cost, and poor long-term reliability. It can be used repeatedly for extended periods and is highly adaptable to various scenarios. Through the cooperation of a press-lock mechanism, a scissor-type telescopic component 8, and a return spring 12, simply pressing the top cover 2 completes the self-locking process, and pressing again unlocks and pops it open. No additional auxiliary operating parts are required, making the opening and closing process simple and convenient, enhancing the sense of ceremony when opening gifts. The ejector pin 16, linked to the scissor-type telescopic component 8, and the rotating plate... The 45 anti-rotation slot 15 works in conjunction to achieve mechanical linkage between lifting and rotation limit. When the lid is closed, the rotating plate 45 is automatically locked to prevent the spring from being released accidentally. When the lid is opened, the limit is automatically released, and the linkage logic is closed-loop and the structure is stable. After the lid is unlocked, the spring rotation drive mechanism 13 can automatically release the stored energy to drive the rotating plate 45 to rotate and form a dynamic display effect with the decorative part 17. This solves the problem of traditional packaging boxes having single function and no dynamic display. Moreover, the overall structure has a high degree of integration, smooth lifting, low assembly difficulty, and controllable cost, making it suitable for packaging scenarios of various high-end gifts and cultural and creative products.

[0031] Specifically, when closing the lid, pressing down on the top cover 2 causes the top plate 7 to move downwards simultaneously. The locking rod 9 is inserted into the locking seat 10 along with the top plate 7, and the self-locking mechanism is pressed to lock the lid, restricting the scissor-type telescopic assembly 8 to a retracted and compressed state. At the same time, the first connecting plate 5 moves downwards as the scissor-type telescopic assembly 8 retracts, compressing the return spring 12 between the first connecting plate 5 and the bottom plate 4, allowing the return spring 12 to store elastic potential energy. When the top cover 2 is pressed again, the self-locking mechanism is pressed to trigger unlocking, the return spring 12 releases the stored elastic potential energy, pushes the first connecting plate 5 upwards, causes the scissor-type telescopic assembly 8 to unfold upwards, and then pushes the top plate 7 and the top cover 2 to pop up simultaneously, completing the opening action.

[0032] When the scissor-type telescopic assembly 8 is in the retracted and locked state, the distance between the second connecting plate 6 and the top plate 7 gradually decreases as the scissor-type telescopic assembly 8 retracts. The ejector pin 16 extends out of the top plate 7, and the top end of the ejector pin 16 is inserted into the anti-rotation groove 15 at the bottom of the rotating plate 45. The circumferential rotation of the rotating plate 45 relative to the top plate 7 is restricted by the contact and limiting of the ejector pin 16 and the anti-rotation protrusion 14. When the scissor-type telescopic assembly 8 unfolds and pops up, the distance between the second connecting plate 6 and the top plate 7 gradually increases as the scissor-type telescopic assembly 8 unfolds. The ejector pin 16 moves downward relative to the top plate 7, so that the top end of the ejector pin 16 disengages from the anti-rotation groove 15, releasing the rotation limitation on the rotating plate 45. At this time, the spring-driven mechanism 13 releases the pre-stored elastic potential energy, and drives the rotating plate 45 to rotate circumferentially relative to the top plate 7 through the output end. The decorative parts 17 on the edge of the rotating plate 45 rotate synchronously with the rotating plate 45, forming a dynamic display effect.

[0033] In this embodiment, a lifting and rotating linkage packaging box is provided. The locking seat 10 has a locking guide hole 18 that runs vertically through it. The inner wall of the locking guide hole 18 is provided with an elastic locking component 19. The outer wall of the locking rod 9 has a locking groove 20 that is adapted to the elastic locking component 19. A movable block 21 is movably sleeved on the outer periphery of the locking groove 20. A first compression spring 22 is provided between the movable block 21 and the bottom inner wall of the locking groove 20. When the locking rod 9 is inserted into the locking guide hole 18 as the top plate 7 descends, the bottom end of the locking rod 9 first pushes the elastic locking component 19 to retract laterally. When the locking slot 20 moves to the corresponding position of the elastic locking component 19, the elastic locking component 19 springs back and locks into the locking slot 20, achieving press-locking. When the top plate 7 is pressed again to drive the locking rod 9 downward, the movable block 21 first abuts against the elastic locking component 19 and descends, compressing the first compression spring 22 until the movable block 21 descends to the bottom of the elastic locking component 19. At this time, the elastic locking component 19 loses its locking limit on the locking rod 9. After the pressed top cover 2 is released, the elastic force of the return spring 12 drives the movable block 21 and the locking rod 9 to move upward together, so that the locking slot 20 completely disengages from the elastic locking component 19, achieving unlocking. The cooperation between the movable block 21 and the first compression spring 22 forms a secondary trigger unlocking logic, which greatly improves the reliability of the self-locking mechanism and effectively avoids problems such as self-locking jamming, mis-locking, and unlocking failure. At the same time, the pressing operation is smoother, and the pressing stroke and force are more uniform, improving the user's operating experience.

[0034] In this embodiment, a lifting and rotating linkage packaging box is provided. The inner wall of the locking guide hole 18 is provided with a positioning hole 23. The elastic locking assembly 19 includes at least one set of elastic blocks 24 and a second compression spring 25. One end of the second compression spring 25 is fixedly connected to the inner wall of the positioning hole 23, and the other end is fixedly connected to the elastic block 24. The top of the side of the elastic block 24 facing the center of the locking guide hole 18 is provided with a guide slope 26 that is adapted to the locking slot 20. The bottom of the locking rod 9 and the top of the movable block 21 are both provided with guide arc surfaces 27. The second compression spring 25 provides a continuous radial preload to the elastic block 24, ensuring that the elastic block 24 always tends to move towards the center of the locking guide hole 18. When the locking rod 9 moves downward, the guide arc surface 27 at its bottom cooperates with the guide slope 26 of the elastic block 24, converting the vertical pressing force into a lateral yielding force, pushing the elastic block 24 to compress the second compression spring 25 and yield laterally. The locking and yielding can be completed without additional operation. When unlocking, the guide arc surface 27 at the top of the movable block 21 cooperates with the bottom of the elastic block 24, and the yielding and disengagement are also smoothly achieved through the slope guide. Specifically, the cooperation between the guide slope 26 and the guide arc surface 27 significantly reduces the frictional resistance during the insertion and removal of the locking rod 9, ensuring the smoothness of the locking and unlocking actions. At the same time, the stable preload provided by the second compression spring 25 ensures that the locking force of the elastic block 24 after it is inserted into the locking slot 20 is stable and uniform, avoiding the problem of loosening in the locked state, and further improving the operational stability and service life of the press self-locking mechanism.

[0035] This embodiment describes a lifting and rotating linkage packaging box. The scissor-type telescopic assembly 8 includes at least two symmetrically arranged scissor arm groups 28. Each scissor arm group 28 includes multiple cross-hinged scissor connecting rods 29. The hinge shafts 30 of adjacent scissor arm groups 28 are coaxially fixed. The lower surface of the top plate 7 is provided with guide grooves 31, and the top of each scissor arm group 28 is provided with sliding pins 32, which slide in cooperation with the corresponding guide grooves 31. Specifically, when the scissor-type telescopic assembly 8 is retracted or extended, the sliding pins 32 at both ends of the scissor arm group 28 reciprocate horizontally along the guide grooves 31. The horizontal displacement of the sliding pins 32 is converted into an angle change of the scissor connecting rods 29, thereby realizing the overall height adjustment. The multiple symmetrically arranged scissor arm groups 28 move synchronously through coaxial hinge shafts 30, ensuring synchronous displacement of each position during the lifting process. By using multiple symmetrically arranged scissor arm assemblies 28 in conjunction with guide grooves 31 and sliding pins 32, the levelness and coaxiality of the top plate 7 are ensured during the lifting process, avoiding problems such as swaying and jamming during lifting. At the same time, the load-bearing capacity of the lifting mechanism 3 is greatly improved, further enhancing the reliability of the product.

[0036] This embodiment describes a lifting and rotating linkage packaging box. The first connecting plate 5 is fixedly connected to the hinge shaft 30 at the lower part of the scissor-type telescopic assembly 8, and the second connecting plate 6 is fixedly connected to the hinge shaft 30 at the upper part of the scissor-type telescopic assembly 8. When the scissor-type telescopic assembly 8 is compressed, the first connecting plate 5 and the second connecting plate 6 move upwards synchronously. When the scissor-type telescopic assembly 8 is extended, the first connecting plate 5 and the second connecting plate 6 move downwards synchronously. Specifically, when the scissor-type telescopic assembly 8 is compressed, the included angle of the cross-hinged scissor links 29 decreases, thereby causing the first connecting plate 5 and the second connecting plate 6 to move upwards synchronously. When the scissor-type telescopic assembly 8 is extended, the included angle of the scissor links 29 increases, and the lower hinge shaft 30 and the middle hinge shaft 30 simultaneously undergo vertical displacement downwards, causing the first connecting plate 5 and the second connecting plate 6 to move downwards synchronously. By directly fixing the two connecting plates to the hinge shaft 30 of the scissor arm assembly 28, the connecting plates and the scissor arm extension and retraction movements can be completely synchronized without the need for additional transmission connecting parts. This ensures the precise synchronization of the self-locking action and the rotation stop action, avoids the problems of trigger delay and limit failure caused by transmission gap, makes the linkage logic of the opening and closing process more reliable, and simplifies the structure and reduces the difficulty of production and assembly.

[0037] In this embodiment, a lifting and rotating linkage packaging box is provided. The top plate 7 has a guide hole 33 corresponding to the ejector pin 16. The ejector pin 16 is vertically fixed to the upper surface of the second connecting plate 6, and passes through the guide hole 33. Specifically, when the second connecting plate 6 moves the ejector pin 16 up and down, the guide hole 33 provides axial guidance and limitation for the ejector pin 16 throughout its movement, ensuring that the ejector pin 16 always makes linear displacement in the vertical direction and does not exhibit radial wobble.

[0038] This embodiment describes a lifting and rotating linkage packaging box. The spring rotation drive mechanism 13 includes a spring box 34, a spring spindle 35, and a spring body 36. The spring box 34 is fixedly installed at the center of the top plate 7. The spring body 36 is housed within the spring box 34. The spring spindle 35 is vertically inserted through the center of the spring box 34. The inner end of the spring body 36 is fixedly connected to the spring spindle 35, and the outer end of the spring body 36 is fixedly connected to the inner wall of the spring box 34. The spring spindle 35 is connected to the rotating plate 45. Specifically, in the closed and locked state, rotating the spring spindle 35 causes the spring body 36 to wind tightly around the spring spindle 35, storing elastic potential energy. When the rotation limit of the rotating plate 45 is released after the lid is opened, the wind-wound spring body 36 releases its elastic potential energy, causing the spring spindle 35 to rotate in the opposite direction, thereby driving the rotating plate 45 to rotate through the transmission structure. The purely mechanical energy storage drive structure, consisting of the spring box 34, the spring spindle 35, and the spring body 36, enables stable rotation of the rotating plate 45 without the need for electricity. It provides long-lasting energy storage and smooth, uniform release, eliminating issues of limited battery life or circuit failures. It can be stored and reused for extended periods. Furthermore, its compact structure allows it to fit within the limited installation space of the top plate 7 of the packaging box without taking up additional storage space for the gift.

[0039] It is understood that the top of the locking rod 9 is connected to the spring box 34, the spring box 34 is connected to the upper cover 2, and the middle part of the locking rod 9 is connected to the top plate 7.

[0040] This embodiment describes a lifting and rotating linkage packaging box. The top of the upper cover 2 is rotatably equipped with a tightening knob 37. The lower end of the tightening knob 37 is coaxially and fixedly connected to the upper end of the mainspring spindle 35. The tightening knob 37 can rotate independently relative to the upper cover 2, driving the mainspring spindle 35 to rotate and tighten the mainspring body 36. Specifically, this simplifies the mainspring tightening process, allowing for convenient mainspring energy storage in the closed and locked state without the need to open the cover.

[0041] The lifting and rotating linkage packaging box described in this embodiment includes a spring-driven rotating mechanism 13 that further includes a speed-increasing gear set 38. The speed-increasing gear set 38 includes a first large gear 39, a first small gear 40, a second large gear 41, and a second small gear 42. The first large gear 39 is coaxially fixed to the spring spindle 35. The first large gear 39 meshes with the first small gear 40. The first small gear 40 is coaxially fixed to the second large gear 41. The second large gear 41 meshes with the second small gear 42. The middle part of the second small gear 42 is connected to the rotating plate 45. Specifically, through a two-stage speed-increasing transmission structure consisting of the first large gear 39, the first small gear 40, the second large gear 41, and the second small gear 42, the output speed of the mainspring spindle 35 is continuously amplified in two stages by utilizing the difference in the gear ratio between the meshing gears. Finally, the increased torque is transmitted to the rotating plate 45 through the second small gear 42, effectively improving the rotation speed and rotation duration of the rotating plate 45. This allows the decorative parts 17 along the edge of the rotating plate 45 to form a more significant and longer-lasting dynamic fluttering display effect, greatly enhancing the visual appeal of the gift packaging box. It combines power and a sense of ceremony; at the same time, it adopts a coaxial fixed gear combination, with a compact transmission structure that occupies little installation space. It can perfectly fit the narrow layout space of the top plate 7 of the packaging box without taking up extra space for gift storage. Moreover, the cylindrical gear transmission has high transmission efficiency and smooth operation, which can ensure that the rotating plate 45 rotates at a uniform speed and smoothly, avoiding problems such as jamming and uneven speed. In addition, this two-stage speed-increasing structure can adapt to the torque decay characteristics during the release of the spring, making up for the speed loss caused by the decrease in spring torque and extending the effective dynamic display time.

[0042] This embodiment describes a lifting and rotating linkage packaging box. The lifting mechanism 3 further includes a telescopic sleeve 43. The bottom plate 4, the first connecting plate 5, the second connecting plate 6, the top plate 7, and the scissor-type telescopic assembly 8 are all disposed within the telescopic sleeve 43. The top of the telescopic sleeve 43 is connected to the inner top wall of the telescopic sleeve 43, and the bottom box 1 is connected to the outer bottom wall of the telescopic sleeve 43. The bottom box 1 has multiple receiving slots 44. Specifically, the telescopic sleeve 43 extends and retracts synchronously with the lifting and lowering of the scissor-type telescopic assembly 8, providing full-stroke coverage and protection for the internal lifting mechanism 3. By covering and protecting the internal moving parts such as the scissor-type telescopic assembly 8 and the self-locking mechanism, the telescopic sleeve 43 avoids the problems of jamming and wear caused by dust and debris entering the moving parts, thus improving the product's service life. At the same time, it ensures the integrity and aesthetics of the product's appearance, preventing the internal mechanical structure from being exposed and affecting the visual effect. In addition, the telescopic sleeve 43 can also provide auxiliary axial guidance for the lifting action, further improving the stability of the lifting process.

[0043] The gift packaging box described in this embodiment has a complete workflow divided into two stages: closing the lid to lock and store energy, and unlocking the lid to display the contents. During the closing and locking energy storage stage: Place the gift on the bottom box 1, press down on the top cover 2, causing the scissor-type telescopic component 8 to retract and compress. The locking rod 9 is inserted into the locking seat 10, and the self-locking mechanism is pressed to complete the locking, keeping the scissor-type telescopic component 8 in the retracted state. At the same time, the return spring 12 is compressed to store elastic potential energy. During the closing process, the second connecting plate 6 moves upward with the retraction of the scissor-type telescopic component 8, causing the ejector pin 16 to engage in the anti-rotation slot 15 at the bottom of the rotating plate 45, locking the circumferential rotation of the rotating plate 45. At this time, by rotating the tightening knob 37, the mainspring spindle 35 is rotated to tighten the mainspring body 36, completing the energy storage. Due to the limitation of the ejector pin 16, the tightened mainspring will not be accidentally released.

[0044] Unlocking and opening display stage: Press the top cover 2 down again to trigger the self-locking mechanism to unlock. The reset spring 12 releases its elastic potential energy, pushing the scissor-type telescopic component 8 to unfold upwards, causing the top plate 7 and the top cover 2 to pop up synchronously to complete the opening. During the opening process, the second connecting plate 6 moves downwards with the unfolding of the scissor-type telescopic component 8, causing the ejector pin 16 to disengage downwards from the anti-rotation slot 15, releasing the rotation limit on the rotating plate 45. At this time, the spring body 36 releases its stored energy, which is amplified by the speed-increasing gear set 38 to drive the rotating plate 45 to rotate at high speed. The decorative parts 17 on the edge of the rotating plate 45 form a dynamic display effect as it rotates, completing the automatic display of the gift.

[0045] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
