Description

Technical Field

[0001] This utility model relates to a storage box. Background Technology

[0002] Currently, most storage box lids on the market are made of a single material, such as pure bamboo or pure plastic. However, these lids have significant drawbacks in actual use:

[0003] 1) Deformation problem of bamboo lid: Although bamboo is environmentally friendly and beautiful, it is prone to warping and deformation due to changes in humidity and temperature in dry or cold environments, which makes it impossible for the lid to close tightly with the box, affecting the sealing performance and the use effect.

[0004] 2) Insufficient structural strength: The pure bamboo board cover lacks rigid support, and long-term load-bearing or frequent opening and closing can easily lead to structural fatigue or even breakage; while using metal profiles (such as aluminum) can enhance strength, but it will sacrifice the natural texture and lightness of bamboo.

[0005] 3) Functional limitations: The handles of existing lids are mostly single-function (only lifting or fastening), lacking an integrated design, which leads to inconvenience in operation or the need to add extra parts, increasing costs.

[0006] To address the aforementioned issues, some existing technologies have attempted to improve the performance of the cover by using composite materials, such as wrapping metal strips around the edges of bamboo panels. However, such designs often only address localized deformation issues without comprehensively considering the integration of snap-fit ​​fixing, load-bearing requirements, and multi-functional handles. Furthermore, the connection stability and durability of the spliced ​​structure have not been adequately optimized, and frequent use can easily lead to loosening or failure of the joints.

[0007] Therefore, there is an urgent need for a new type of storage box lid structure that combines bamboo and aluminum profiles. This structure retains the aesthetic appeal of bamboo while utilizing the rigidity of aluminum profiles to suppress deformation, provide a snap-fit ​​mechanism, and enhance load-bearing capacity. It also integrates a dual-function handle for both lifting and snapping to improve practicality and lifespan. Utility Model Content

[0008] This invention provides a storage box that can effectively solve the above-mentioned problems.

[0009] This utility model is implemented as follows:

[0010] A storage box, including

[0011] Box;

[0012] The buckle assembly symmetrically arranged on both sides of the box body includes a rotatable buckle rod, on which a buckle part and a bent part are integrally formed;

[0013] The gripping component is detachably mounted on the bent portion;

[0015] The beneficial effects of this utility model are:

[0016] (1) This utility model storage box achieves a perfect balance between a stable and secure lid and convenient operation by combining an innovative composite top plate design with a multi-functional buckle assembly: the integrated clamping rods symmetrically arranged on both sides generate a strong axial clamping force through the cooperation of the inclined surfaces when rotating, ensuring that the top plate assembly is tightly fixed; the detachable gripping assembly is cleverly integrated into the clamping rod structure, realizing seamless switching between opening and closing and carrying functions; the specially designed composite top plate adopts a differentiated combination of natural materials and metal profiles, which not only retains the natural beauty, but also effectively prevents deformation through rigidity complementarity.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0031] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Reference Figure 1-6 As shown, a storage box includes a box body 10; both sides of the box body 10 have preset grooves 40, and mounting plates 50 are disposed in the preset grooves 40.

[0033] The buckle assembly 20 is symmetrically arranged on both sides of the box body 10. It includes a rotatable buckle rod 206, on which a buckle part 2060 and a bending part 2062 are integrally formed. The buckle assembly 20 also includes a connector 200 fixed to the box body 10. The connector 200 is provided with a bending protrusion 202, and the buckle rod 206 is connected to the bending protrusion 202 to form a rotating pair. The buckle part 2060 is fitted with a hollow sleeve 208.

[0034] The hollow sleeve 208 is rotatably connected to the fastening part 2060. During installation, the hollow sleeve 208 directly engages with one side of the fastening protrusion 3060 by rolling, and the rolling resistance is small, thus allowing for relatively effortless fastening of the fastening part 2060 and the fastening protrusion 3060. It should be noted that the hollow sleeve 208 in this case is made of metal, but may also be made of plastic. This case does not limit the material; the design can be based on actual needs.

[0035] Furthermore, the locking rod 206 forms a low-resistance rotating pair through the bent protrusion 202 on the through connector 200, and its integrally formed fastening part 2060 and bent part 2062 constitute a force-saving lever structure; when the locking rod is rotated, the hollow sleeve 208 sleeved on the fastening part 2060 forms a beveled pressing fit with the fastening protrusion 3060 of the top plate assembly 306. Through the optimized tilt angle design of 15°±2°, the rotational torque is efficiently converted into axial locking force, which can then press and fix the top plate (cover plate).

[0036] The grip assembly is detachably mounted on the bend 2062; the grip assembly includes a double-ended connecting rod 210 that passes through the bend 2062, a grip sleeve 212 that is rotatably sleeved on the double-ended connecting rod 210, and limiting members 214 that are detachably mounted on both ends of the double-ended connecting rod 210.

[0037] The top plate assembly 30 covers the top of the housing 10 and includes: a first plate 300 and a second plate 302 made of a first material, and an intermediate plate 304 made of a second material; an assembly 306 is disposed on both sides of the intermediate plate 304, and the top of the assembly 306 is provided with a fastening protrusion 3060 that matches the fastening part 2060; the cooperation between the fastening part 2060 and the fastening protrusion 3060 causes an axial clamping force to be generated when the locking rod 206 is rotated to fix the top plate assembly 30.

[0038] The first material is bamboo or wood-based panels, and the second material is aluminum or steel profiles.

[0039] Example 1 (Bamboo + Aluminum Profile)

[0040] The top panel assembly comprises a first panel 300 and a second panel 302 made of carbonized bamboo, with their fiber direction arranged parallel to the long side of the housing. They are interference-fitted with the clamping groove 3044 of the 6063 aluminum alloy intermediate panel 304 via a T-shaped interlocking part 3000. This assembly utilizes the low longitudinal thermal expansion coefficient of bamboo, approximately 5.4 × 10⁻⁶. -6 The characteristic of / ℃ complements the high rigidity of aluminum alloy, which effectively restrains the expansion and contraction of bamboo boards during seasonal changes. Actual measurements show that warping deformation is reduced by more than 70% compared to pure bamboo board covers.

[0041] Adaptability: Suitable for home storage, combining aesthetics and durability.

[0042] Example 2: Engineering Plastic + Steel Profile Combination

[0043] The first panel 300 and the second panel 302 are injection molded from 30% glass fiber reinforced polypropylene (PP) + 30GF, with the injection flow direction aligned with the force direction. The intermediate panel 304 is a 304 stainless steel rectangular tube, joined to the plastic panels via ultrasonic welding. This structure utilizes the corrosion resistance of stainless steel (showing no significant rust after a 48-hour salt spray test) and the cushioning properties of plastic to effectively resist impacts during logistics transportation. Drop tests show no cracking at the top panel joints after a free fall from a height of 1.2m.

[0044] Adaptability: Meets the corrosion resistance and impact resistance requirements of industrial logistics.

[0045] Example 3: Lightweight Bamboo-Plastic-Magnesium Alloy Structure

[0046] The first plate 300 and the second plate 302 are made of bamboo fiber and high-density polyethylene composite extrusion molding with a bamboo fiber content of 60wt%. The intermediate plate 304 is made of thin-walled magnesium alloy profile AZ91D. This combination improves the vibration attenuation rate by 40% through the damping characteristics of the bamboo-plastic composite material and the high specific strength elastic modulus of magnesium alloy (45GPa). It is particularly suitable for packaging precision instruments that require shock absorption and noise reduction. In actual transport vibration tests, the peak acceleration inside the box was reduced by 35dB.

[0047] Compatibility: Suitable for packaging precision instruments, providing excellent shock absorption performance.

[0048] Conclusion: By combining natural materials with high expansion coefficients, such as bamboo and wood, with high-rigidity metal profiles, such as aluminum alloy, through specific interlocking and screwing methods, along with a rotating buckle mechanism with a hollow sleeve 208 and detachable multi-functional grip components, this method effectively solves the technical problems of traditional storage box lids being prone to deformation and having poor sealing. While maintaining the aesthetic appeal of natural materials, it significantly improves structural stability and load-bearing capacity. Its modular design makes assembly and maintenance more convenient, and multiple material combination schemes can meet the needs of different usage scenarios. It also has the comprehensive advantages of moisture resistance, weather resistance, and long-term use. It has made outstanding progress in terms of structural innovation, functional practicality, and process feasibility, providing an optimized solution for the storage container field that balances environmental protection, durability, and ease of operation.

[0049] Reference Figure 7 As shown, the connector 200 has an opening that communicates with the bent protrusion 202. This opening is used for the lever 206 to detach downwards or to snap into place quickly, thereby facilitating the quick assembly and disassembly of the lever 206 and the gripping assembly, and thus reducing the overall storage volume of the housing 10.

[0050] The first plate 300 and the second plate 302 are provided with a plug-in portion 3000 at their joint ends. The middle plate 304 is provided with side clamping plates 3042 with clamping grooves 3044 on both sides. The plug-in portion 3000 and the clamping grooves 3044 are interference fit.

[0051] The top of the intermediate plate 304 is provided with several upper protrusions 3040.

[0052] The spacing between adjacent 3040 upper ribs is 5-10 mm. In one embodiment, this spacing design first ensures an optimal weight-to-stiffness ratio, providing a 28% increase in the moment of inertia at a spacing of approximately 5 mm (compared to a flat plate structure), while maintaining a 15% stiffness gain even when the spacing is increased to approximately 10 mm, while reducing material usage by 22%. Secondly, the corrugated structure formed by this specific spacing range effectively suppresses resonance. The spacing control also optimizes load distribution capabilities. Under a concentrated load of 30 kg, the approximately 5 mm spacing rib structure reduces the stress concentration factor to 1.8 (compared to 3.2 for a flat plate structure), while the approximately 10 mm spacing version exhibits better resistance to localized impacts, reducing dent depth by 63% in drop ball tests, and providing uniform fluid flow channels for subsequent surface treatments (such as anodizing).

[0053] In one embodiment, the upper ridge 3040 includes, but is not limited to:

[0054] 1) Continuous protrusions: parallel straight ridges, wavy continuous ridges, etc.;

[0055] 2) Discontinuous protrusions: arrayed hemispherical protrusions, trapezoidal block protrusions, etc.;

[0056] 3) Composite structure: cross-shaped grid-like ribs, radially distributed fan-shaped ribs, etc.;

[0057] 4) Variable cross-section design: ridge-like protrusions with a platform at the top, gradually deformed ridges, etc.

[0058] In practical implementation: for metal intermediate plates, it is recommended to use extruded continuous straight ribs; for plastic intermediate plates, injection molded mesh composite ribs are preferred; under special working conditions, variable cross-section rib structures can be used to adapt to specific load requirements.

[0059] This case does not impose too many restrictions; you can set it up according to your actual needs.

[0060] The middle part of the assembly 306 also has an assembly groove 3062 for mounting with the plug-in part 3000, a parallel part 3064 formed at the opening of the assembly groove 3062, and an inner protrusion 3066 symmetrically arranged inside the assembly groove 3062; the assembly 306 also has a first screw hole 3068 and a second screw hole 3070 for connecting with the plug-in part 3000.

[0061] Working principle: By forming an interference fit between the insertion part 3000 of the bamboo / wooden first panel 300 and the clamping groove 3044 on both sides of the metal intermediate panel 304, and using the assembly groove 3062 and inner protrusion 3066 of the assembly part 306 for positioning and reinforcement, and then fixing it with bolts through the first screw hole 3068 and the second screw hole 3070, a composite top plate structure combining rigidity and flexibility is constructed; when the lid is closed, rotating the two side locking rods 206 causes their fastening parts 2060 to drive the hollow sleeve 20 The 8 and the snap-fit ​​protrusion 3060 on the assembly 306 form a beveled pressing fit, generating axial locking force to achieve sealing and fixation. At the same time, the detachable grip components 210 / 212 / 214 on the bent part 2062 can be converted into handles at any time. The upper protrusion 3040 on the top of the metal intermediate plate 304 enhances the structural rigidity, while the mounting connecting plate 50 in the preset groove 40 improves the deformation resistance of the box side wall. The whole system achieves the unity of deformation resistance, easy operation and long service life through complementary material properties and mechanical interlocking design.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
