Description

Technical Field

[0001] This invention belongs to the field of packaging boxes, specifically a packaging box with an adjustable lifting structure. Background Technology

[0002] In the product packaging and storage industry, lift-up packaging boxes are commonly used for storing and displaying aesthetically pleasing items such as handicrafts and jewelry. Currently, traditional lift-up packaging boxes on the market have a fixed internal support structure height, which cannot be adjusted according to product specifications. During use, the fixed lifting height makes it difficult to adapt to products of different heights and sizes, resulting in a narrow range of compatibility and poor versatility. This can easily lead to products becoming loose, wobbling, or shifting, and are prone to damage during transportation. Furthermore, traditional packaging boxes cannot achieve multi-level adaptive lifting adjustment, requiring different sized boxes for different products, leading to high packaging adaptation costs and cumbersome replacements, thus reducing the practicality and convenience of packaging and storage. Summary of the Invention

[0003] The purpose of this invention is to provide a packaging box with an adjustable lifting height to solve the problem of fixed lifting height in traditional packaging boxes.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A packaging box with an adjustable lifting height includes a packaging box body, a lifting platform, traction belts, and a flip-out outer box that can be flipped and connected to both sides of the packaging box body. The traction belt has two sections, with their outer ends connected to the flip-out outer box and their inner ends penetrating the wall of the packaging box body and connected to the lifting platform. Flipping the flip-out outer box causes the lifting platform to rise or fall. The lifting platform has an upwardly extending support member, and the upper surface of the packaging box body has a through hole adapted to the upper end of the support member. The support member includes a base, a transmission member, and a lifting member sleeved on the base. The lower end of the lifting member has a lifting ramp, and the base has a transmission member through hole. The transmission member can slide through the transmission member through hole, abutting against or moving away from the lifting ramp. The inner wall of the upper part of the packaging box body has an abutment adapted to the transmission member. When the lifting platform rises, the transmission member approaches the abutment, pushing the transmission member against the lifting ramp, thereby pushing the lifting member upward.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] By flipping the outer box and using a traction belt to raise or lower the lifting platform, the lifting height of the platform and its supporting components can be adjusted as needed, utilizing the internal space of the packaging box to improve packaging adaptability. Simultaneously, the cooperation between the transmission component and the lifting ramp in the supporting component allows the transmission component to be pushed against the lifting ramp as the platform rises, due to its proximity to the inner wall of the packaging box, thus lifting the supporting component and providing support for items placed on it. The coordinated operation of the traction belt, flipping outer box, transmission component, and lifting ramp creates a two-stage lifting mechanism. Firstly, the degree of flipping the outer box controls the lifting distance; secondly, during storage, the platform has a large descent space, improving its adaptability to the thickness of items it can support. The overall structure requires no complex electronic equipment or additional power source, resulting in low cost, high reliability, and easy operation.

[0008] Preferably, the transmission component includes a guide rail and a sliding abutment; the guide rail is located on the periphery of the base, and the sliding abutment is slidably connected to the guide rail. The guide rail is installed on the periphery of the base, and the sliding abutment, which is slidable to it, faces the base to complete the abutment operation.

[0009] Preferably, one end of the sliding abutment is provided with an abutment slope that is adapted to the lifting slope. The abutment surface provided on one side of the sliding abutment can complete the abutment quickly and more stably.

[0010] Preferably, the guide rail is provided with a spring, and the sliding abutment is elastically connected to the guide rail by the spring. After the entire lifting process is completed, the spring can cause the sliding abutment to return to its original position.

[0011] Preferably, the lifting platform is provided with a through hole, and the through hole is located between the guide rails. The through hole is adapted to the abutment member. The through hole is opened on the lifting platform and is located below the abutment member. The size of the through hole can also be adapted to the abutment member to complete the abutment work. The abutment member is wedge-shaped.

[0012] Preferably, the upper end of the packaging box body is open, and a limiting plate is provided at the opening of the packaging box body. The limiting plate is fixed to the opening of the packaging box body by an adhesive strip. The upper end of the packaging box body is open, and the limiting plate at the opening prevents the items inside the box from sliding out, while also providing support for the force required during the contact process. The limiting plate is connected to the packaging box body by an adhesive strip, which facilitates disassembly and replacement of internal parts.

[0013] Preferably, the through hole is formed on the limiting plate, and the abutting member is integrally formed with the limiting plate. The through hole is formed in the middle of the limiting plate, so that the bearing member can pass through the through hole.

[0014] Preferably, the packaging box body has several flip angle adjustment strips on both sides. The flip angle adjustment strips are arc-shaped and are fixedly installed on one side of the packaging box body, so that the lifting height of the adjustment platform is adjustable, and thus affects the lifting height of the carrier. The arc shape of the adjustment strips allows the matching closed cover to complete the angle adjustment on the outward flipping trajectory.

[0015] Preferably, the flip angle adjustment strip is provided with a plurality of limiting holes, and the flip outer box is provided with through holes that are adapted to the limiting holes. The limiting holes and through holes are adapted to each other and can fit together better.

[0016] Preferably, the flip-top outer box is provided with a hanging rope, and the hanging rope is provided with a post. When adjusting the flip-top angle of the flip-top outer box, the post passes through the perforation and is inserted into the limiting hole. The hanging rope is outside the closed cover and is fixed to the post so that it will not fall off. When the desired angle is adjusted, the post is directly inserted into the limiting hole to complete the adjustment. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See Figure 1 - Figure 4 This invention provides a packaging box with an adjustable lifting height. It comprises a packaging box body 11, a lifting platform 12, traction belts 13, and a flip-out outer box 14 connected to both sides of the packaging box body 11, forming a packaging box with adjustable lifting height. Two traction belts 13 are provided, with their outer ends connected to the flip-out outer box 14 and their inner ends penetrating the wall of the packaging box body 11 and connected to the lifting platform 12. When the outer box 14 is flipped, the movement of the traction belts 13 causes the lifting platform 12 to rise or fall, adjusting the lifting height of the lifting platform 12 and the supporting components as needed. This utilizes the internal space of the packaging box, meets the packaging needs of items of different sizes, improves packaging adaptability, and solves the problem of inconvenient space utilization and inability to adapt to packaging of various sizes of items in traditional packaging boxes.

[0027] The carrier uses a combination of a base 16, a transmission component, and a lifting component 17 fitted onto the base 16. The lower end of the lifting component 17 has a lifting ramp, and the base 16 has a through hole for the transmission component. The transmission component can slide through the through hole to abut against or move away from the lifting ramp. At the same time, an abutment component 18 adapted to the transmission component is provided on the upper inner wall of the packaging box body 11. When the lifting platform 12 rises, the transmission component comes into contact with the abutment component 18 and is pushed against the lifting ramp, causing the lifting component 17 to rise. This provides stable support for the items placed on the carrier, prevents the items from shaking or shifting inside the packaging box, improves the safety of the items during transportation, and solves the problem of items being damaged due to shaking during transportation.

[0028] The transmission component includes a guide rail 19 and a sliding abutment 21. The guide rail 19 is located around the base 16, and the sliding abutment 21 is slidably connected to the guide rail 19. The guide rail 19 is installed around the base 16, and the sliding abutment 21, which is slidable to it, faces the base 16, enabling it to stably complete the abutment operation. One end of the sliding abutment 21 has an abutment slope adapted to the lifting slope. The abutment surface on one side not only allows for quick abutment with the lifting slope but also provides greater stability during the abutment process, further improving the reliability of the support component for the object. In addition, the guide rail 19 is equipped with a spring, and the sliding abutment 21 is elastically connected to the guide rail 19 via the spring. After the entire lifting process is completed, the spring allows the sliding abutment 21 to return to its original position, ensuring the stability and reliability of the transmission component during multiple uses and solving the problem of inconvenient reset of the transmission component, which affects the effectiveness of multiple uses.

[0029] The lifting platform 12 is provided with a through hole 15, which is located between the guide rails 19 and is adapted to the abutment member 18. The through hole 15 is opened on the lifting platform 12 and is located below the abutment member 18. The size of the through hole 15 is also adapted to the abutment member 18, so as to successfully complete the abutment work. The abutment member 18 is wedge-shaped and cooperates with the through hole 15 and the transmission member to ensure that the transmission member is pushed by the abutment member 18 during the lifting process of the lifting platform 12, thereby realizing the lifting action of the lifting member 17 and improving the stability of the lifting action of the entire lifting structure.

[0030] The upper part of the packaging box body 11 is open, and a limiting plate 22 is provided at the opening. The limiting plate 22 is fixed to the opening of the packaging box body 11 by an adhesive strip. On the one hand, it prevents the objects inside the box from sliding out, and on the other hand, it provides support for the force required during the abutment process, ensuring the stability of the lifting structure. On the other hand, the limiting plate 22 is connected to the packaging box body 11 by the adhesive strip, which is convenient for disassembly and replacement of internal parts, improving the maintenance convenience of the packaging box and solving the problems of difficult maintenance and inconvenient replacement of internal parts in traditional packaging boxes. A through hole 15 is opened on the limiting plate 22, and the abutment member 18 is integrally formed with the limiting plate 22. The through hole 15 is opened in the middle of the limiting plate 22, so that the load-bearing member can pass smoothly through the through hole 15, which enhances the stability of the structure and reduces production costs.

[0031] The packaging box body 11 has several tilt angle adjustment strips 23 on both sides. These strips are arc-shaped and fixedly installed on one side of the packaging box body 11. Their purpose is to adjust the lifting height of the lifting platform 12, thereby affecting the lifting height of the load-bearing component. The arc shape of these adjustment strips allows them to adapt well to the outward tilting trajectory of the outer box 14, thus achieving angle adjustment. The tilt angle adjustment strips 23 have several limiting holes, and the outer box 14 has through holes that match these limiting holes. This mutual adaptation allows for better coordination and angle adjustment. The outer box 14 is equipped with a hanging rope 24, and the hanging rope 24 has an insert post. When adjusting the flipping angle of the outer box 14, simply insert the insert post through the through hole into the limiting hole. The hanging rope 24 is set on the outside of the outer box 14 and fixed to the insert post, making the connection secure. When adjusting to the required angle, simply insert the insert post into the limiting hole to complete the adjustment conveniently. This makes the angle adjustment operation of the outer box 14 simpler, improves the convenience of using the packaging box, and solves the problem of inconvenient adjustment of the flipping angle of traditional packaging boxes, which affects the control of lifting height.
