Description

Technical Field

[0001] This utility model relates to the field of storage products technology, and more specifically, to a parts box. Background Technology

[0002] Modular parts boxes (also known as modular parts boxes) are a widely used warehousing and logistics container, favored for their flexible combination methods, and are widely used in many industries such as electronics, machinery, pharmaceuticals, and automobile manufacturing.

[0003] However, most modular parts boxes on the market today have a vertical sidewall structure to maintain stable assembly and storage space. With this structure, when the parts boxes are empty and need to be transported or stored, they must be stacked individually, leaving complete internal space between the boxes. This results in excessive space occupied during transportation and storage, large transport volume, and high logistics costs. Utility Model Content

[0004] The purpose of this utility model is to provide a parts box to alleviate the technical problem in the prior art where parts boxes, when empty, need to be stacked individually for transportation or storage, leaving complete internal space between boxes, resulting in excessive space occupation during transportation and storage, large transportation volume, and high logistics costs.

[0005] This utility model provides a parts box for storing parts and includes a base plate and a side plate. The side plate is disposed on the base plate along the circumference of the base plate, and the side plate and the base plate together form a storage groove with the opening opposite to the base plate.

[0006] The side plate is inclined, and the angle between the side plate and the vertical direction is greater than or equal to 3° and less than or equal to 15°, so that the projection of the opening of the storage slot on the horizontal plane can cover the outer contour of the bottom plate.

[0007] Furthermore, the angle between the side panel and the vertical direction is 7°.

[0008] Furthermore, the parts box also includes a connecting support.

[0009] The side plate has a first connecting part at one end away from the bottom of the storage compartment, which is adapted to one end of the connecting support member.

[0010] The bottom surface of the base plate is provided with a second connecting part that is adapted to the other end of the connecting support.

[0011] Both ends of the connecting support can be detachably connected to the first connecting part or the second connecting part, respectively.

[0012] Furthermore, the first connecting portion includes a plurality of insertion holes.

[0013] The plurality of the insertion holes are arranged at circumferential intervals along the storage slot.

[0014] One end of the connecting support is inserted into the insertion hole.

[0015] Furthermore, the second connecting portion includes multiple slots.

[0016] Each of the slots and the plug-in holes is provided in a one-to-one correspondence.

[0017] One end of the connecting support is inserted into the slot.

[0018] The slot and the insertion hole have different cross-sectional shapes.

[0019] Furthermore, a thickened portion is provided at one end of the side plate away from the bottom of the storage compartment.

[0020] The thickened portion is located on the outside of the storage compartment and extends away from the storage compartment.

[0021] The thickened portion has an anti-shrinkage structure on the side facing the storage compartment. The anti-shrinkage structure is located on the inner wall of the storage compartment and is concave.

[0022] Furthermore, the connecting support includes a first plug-in section, a second plug-in section, and a connecting section.

[0023] The first plug segment is adapted to the first connecting part.

[0024] The second plug segment extends in the same direction as the first plug segment and is adapted to the second connecting portion.

[0025] The two ends of the connecting segment are connected to the first plug segment and the second plug segment respectively. The connecting segment is inclined relative to the first plug segment and the second plug segment so that the first plug segment and the second plug segment are misaligned.

[0026] The connecting segment has an arc-shaped structure.

[0027] Furthermore, a third connecting portion and a fourth connecting portion are provided on the side of the side plate away from the storage compartment.

[0028] The third connecting part and the fourth connecting part are adapted to form a detachable connection, and the third connecting part and the fourth connecting part are disposed opposite each other on both sides of the storage slot.

[0029] Furthermore, the side panel includes a front panel and a peripheral panel that surrounds the front panel to form the wall of the storage compartment.

[0030] The height of the front plate is less than that of the peripheral plate.

[0031] The peripheral plate has inclined structures at both ends, and the lower end of the inclined structure is connected to the front plate.

[0032] Furthermore, the side plate has an outer edge at the end furthest from the storage compartment.

[0033] The outer edge is located on the side of the side plate opposite to the storage compartment and extends away from the storage compartment.

[0034] Beneficial effects: Specifically, in the parts box provided by this utility model, the side plates are inclined and enclose the bottom plate to form a storage slot for storing parts. The storage slot gradually narrows from the opening to the bottom, and the projection of the opening of the storage slot on the horizontal plane can cover the outline of the bottom plate. That is, the bottom of one parts box can be inserted into the storage slot of another parts box through the opening of the storage slot, so that multiple different parts boxes can be nested and stacked in an empty state, which greatly reduces the total volume after stacking and overcomes the defect that traditional modular parts boxes cannot be stacked and stored. It significantly improves space utilization and reduces logistics costs during transportation and storage. Furthermore, while maintaining the original assembly flexibility and loading performance of the parts box, it optimizes resource utilization and improves the economic and environmental benefits of the product.

[0044] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0045] See Figures 1 to 10 The parts box provided in this embodiment is used to store parts. The parts box specifically includes a base plate 100 and a side plate 200. The side plate 200 is disposed on the base plate 100 along the circumference of the base plate 100. The side plate 200 and the base plate 100 together form a storage slot with the opening opposite to the base plate 100.

[0046] In this embodiment, the side plate 200 is inclined, and the angle between the side plate 200 and the vertical direction is greater than or equal to 3° and less than or equal to 15°, so that the projection of the opening of the storage slot on the horizontal plane can cover the outline outside the bottom plate 100.

[0047] Specifically, in this embodiment, the side plate 200 is inclinedly disposed on the bottom plate 100 and together with the bottom plate 100 forms a storage groove for storing parts. The side plate 200 is the groove wall of the storage groove, and the bottom plate 100 is the bottom of the storage groove.

[0048] In this structure, the storage compartment tapers from the opening to the bottom, and the projection of the opening onto the horizontal plane can cover the outline of the base plate 100. This means that one parts box can be inserted into the storage compartment of another parts box through the opening of its storage compartment. Combined with... Figure 3 As shown, multiple different parts boxes can be nested and stacked together when empty, thereby reducing the total volume after stacking and overcoming the shortcomings of traditional modular parts boxes that cannot be stacked for storage. This significantly improves space utilization and reduces logistics costs during transportation and storage. Furthermore, while maintaining the original assembly flexibility and loading performance of the parts boxes, resource utilization is optimized, and the product's economy and environmental friendliness are improved.

[0049] See Figure 6 , Figure 6 In this embodiment, the included angle α is the angle formed by the side plate 200 and the vertical direction, ranging from greater than or equal to 3° to less than or equal to 15°. In this embodiment, the minimum demolding angle for injection molding is 1°. The lower limit of this range (≥3°) not only meets the minimum demolding angle (1°) process requirement for injection molding but also further ensures that the parts box can achieve effective nesting. Simultaneously, the upper limit (≤15°) controls the volume loss caused by the side wall inclination, guaranteeing the practical loading capacity of the parts box.

[0050] Specifically, in this embodiment, the side plate 200 forms a 7° angle with the vertical direction. With this structure, the total volume of the two nested parts boxes is only about 126% of the volume of a single nested parts box. Compared to traditional parts boxes that cannot be nested, the parts box provided in this embodiment achieves a space saving of up to approximately 74%, greatly improving logistics and storage efficiency, while keeping the volume loss of the parts box itself to a small extent.

[0051] In this embodiment, the parts box also includes a connecting support 300.

[0052] The side plate 200 has a first connecting portion 210 at one end away from the bottom of the storage compartment, which is adapted to one end of the connecting support member 300. The bottom surface of the bottom plate 100 has a second connecting portion 110 adapted to the other end of the connecting support member 300. Both ends of the connecting support member 300 can be detachably connected to the first connecting portion 210 and the second connecting portion 110, respectively.

[0053] In this embodiment, one end of the connecting support member 300 is detachably connected to the top of the side plate 200 of the upper part box via the first connecting part 210, and the other end is detachably connected to the bottom surface of the bottom plate 100 of the lower part box via the second connecting part 110, thereby establishing a stable support structure between the upper and lower part boxes.

[0054] See Figure 4The two ends of the connecting support 300 are respectively connected to the first connecting part 210 and the second connecting part 110. Since the first connecting part 210 and the second connecting part 110 are located at different positions in the horizontal direction, the projections of the two ends of the connecting support 300 on the horizontal plane are located at different positions, that is, the first connecting part 210 and the second connecting part 110 are staggered, and the two ends of the connecting support 300 are on an oblique line. With this structure, it is ensured that the weight of the upper part box can be effectively transferred and distributed through the support during multi-layer assembly, avoiding the risk of damage to the side plate 200 or the connecting structure due to stress concentration, and improving the overall structural strength and load-bearing capacity of the part box in the assembled state. At the same time, the detachable connection between the connecting support 300 and the connecting part continues and enhances the flexibility and convenience of assembling the part box.

[0055] In this embodiment, the first connecting portion 210 includes a plurality of insertion holes. The plurality of insertion holes are spaced apart circumferentially along the storage slot. One end of the connecting support 300 is inserted into the insertion hole.

[0056] Multiple insertion holes provide several selectable, discrete mounting positions for the connecting support 300. During the assembly of the upper and lower component boxes, symmetrical or specific insertion points can be flexibly selected for connection based on actual load-bearing and stability requirements. This multi-connection layout helps distribute the upper load more evenly across the circumferential sidewalls of the lower component box, further optimizing the force transmission path and effectively preventing excessive local stress and structural deformation that might occur due to too few or concentrated connection points. This enhances the overall stability and balance of the assembled stack.

[0057] In this embodiment, the second connecting part 110 includes multiple slots. The multiple slots are arranged in a one-to-one correspondence with multiple insertion holes, and the other end of the connecting support 300 is inserted into the slot.

[0058] It should be noted that in this embodiment, the slot and the plug hole have different cross-sectional shapes.

[0059] In this embodiment, the multiple slots correspond one-to-one with the multiple insertion holes provided on the top, providing a precise alignment connection scheme for the two ends of the connecting support 300, ensuring direct and smooth force transmission during assembly, and improving the convenience of assembly operation and the overall alignment of the structure.

[0060] Furthermore, in this embodiment, the slot and the insertion hole adopt different cross-sectional shapes, forming an effective "foolproof" structure. This physically prevents forced assembly of the connecting support 300 due to incorrect orientation or misjudgment of position during installation, not only avoiding damage to the connecting parts and the main body of the parts box, but also significantly reducing the difficulty of operation and improving assembly efficiency and reliability.

[0061] Specifically, please combine Figure 5 In this embodiment, the cross-section of the insertion hole is "H"-shaped, and the cross-section of the slot is "U"-shaped. Utilizing the central symmetry of the H-shape and the directional difference of the U-shape, a clear and reliable foolproof structure is constructed. Correspondingly, the two ends of the connecting support 300 have "H"-shaped and "U"-shaped inserts, respectively, ensuring that during installation, both ends of the connecting support 300 must precisely match the corresponding H-shaped insertion hole and U-shaped slot, physically preventing any possibility of incorrect installation.

[0062] In addition, the H-shaped cross section, due to its symmetry, can better withstand forces in multiple directions, enhancing the stability of the connection point, while the U-shaped cross section is easier to injection mold and demold.

[0063] In this embodiment, a thickened portion 220 is provided at one end of the side plate 200 away from the bottom of the storage compartment.

[0064] The thickened portion 220 is located on the outside of the storage compartment and extends away from the storage compartment. A shrinkage-prevention structure 221 is provided on the side of the thickened portion 220 facing the storage compartment. The shrinkage-prevention structure 221 is located on the inner wall of the storage compartment and is concave.

[0065] Specifically, the thickened portion 220 provided at the top of the side plate 200 in this embodiment can enhance the material thickness and structural strength of the connection area, so that the top structure of the parts box can better bear and disperse the load from the connecting support 300 and the upper stacked items, effectively preventing deformation or cracking of this part due to stress concentration.

[0066] Meanwhile, a concave anti-shrinkage structure 221 is provided on the side of the thickened part 220 facing the storage compartment. The concave structure compensates for the accumulation of internal material caused by the external thickening, so that the cooling rate of each part is more consistent when the part is cooled and formed, thereby avoiding appearance defects such as shrinkage marks and dents on the outer surface due to uneven wall thickness.

[0067] It should be noted that in this embodiment, the slots are disposed on the thickened portion 220, and there are four slots and four thickened portions 220, which are symmetrically distributed on opposite sides of the parts box. The thickened portion 220 provides a thicker material base for the slots, significantly enhancing the local strength and rigidity around the corresponding slots, making the slots less prone to cracking or wear under frequent insertion and removal and bearing upper loads, thereby greatly improving the durability and reliability of the connection structure.

[0068] Meanwhile, the four slots form four connection points that constitute a stable and balanced support system. When the connecting support 300 is inserted, it can evenly distribute the upper load to both sides of the entire parts box, greatly improving the overall stability and anti-tipping ability during assembly and stacking, especially suitable for situations with uneven load distribution or lateral forces. In addition, the symmetrical arrangement of the four thickened parts 220 also evenly strengthens the overall structural rigidity at the slots of the parts box.

[0069] Combination Figures 7 to 10 In this embodiment, the connecting support 300 includes a first insertion segment 310, a second insertion segment 320, and a connecting segment 330.

[0070] The first plug-in segment 310 is adapted to the first connecting portion 210. The second plug-in segment 320 extends in the same direction as the first plug-in segment 310 and is adapted to the second connecting portion 110. The two ends of the connecting segment 330 are connected to the first plug-in segment 310 and the second plug-in segment 320 respectively. The connecting segment 330 is inclined relative to the first plug-in segment 310 and the second plug-in segment 320 so that the first plug-in segment 310 and the second plug-in segment 320 are misaligned.

[0071] In this embodiment, the first insertion segment 310 and the second insertion segment 320 are spatially misaligned so that the connecting support 300 presents an inclined support state between the upper and lower parts boxes, rather than a simple vertical pillar. When subjected to upper layer loads, the force can be effectively transformed into a more reasonable force flow path through the inclined connecting segment 330, thereby dispersing the stress applied to the first connecting part 210 and the second connecting part 110, improving the stress condition of the connection point, avoiding the risk of structural damage caused by local stress concentration, and improving the stability and structural reliability of the parts box when subjected to eccentric loads or dynamic loads.

[0072] In this embodiment, the connecting segment 330 is specifically an arc-shaped structure.

[0073] The curved structure allows forces acting on the connecting support 300 to be transmitted along a smooth curved path, thereby further optimizing force transmission and eliminating stress concentration points that may be caused by sharp or right-angle turns, resulting in a more uniform stress distribution. Compared with inclined planar structures, the curved structure can more effectively convert vertical pressure and lateral impact forces into compressive and tensile stresses within the structure when bearing loads, thus improving the bending and fatigue resistance of the connecting support 300 and enhancing its reliability under long-term, repeated use.

[0074] Furthermore, in this embodiment, the side of the connecting segment 330 is provided with multiple reinforcing ribs 331, and the multiple reinforcing ribs 331 together with the body of the connecting segment 330 form multiple triangular structures to optimize the stress pattern of the connection. The multiple triangular structures constitute the supporting skeleton of the connecting segment 330 to decompose and transfer the complex loads (such as bending stress and torsional load) borne by the connecting segment 330, suppressing the deformation tendency of the connecting segment 330 under stress, and in particular preventing the lateral buckling or torsion that may occur in the arc-shaped connecting segment 330, thereby enhancing the bending and torsional stiffness of the connecting segment 330 and the overall structural stability.

[0075] In this embodiment, a third connecting portion 230 and a fourth connecting portion 240 are provided on the side of the side plate 200 away from the storage compartment. The third connecting portion 230 and the fourth connecting portion 240 are adapted to be detachably connected, and the third connecting portion 230 and the fourth connecting portion 240 are disposed opposite each other on both sides of the storage compartment.

[0076] The third connecting part 230 and the fourth connecting part 240 are positioned opposite each other on both sides of the storage slot to provide the parts box with the ability to connect laterally. Multiple parts boxes can not only be stacked vertically, but also connected side by side in the horizontal direction. They can be flexibly expanded into larger combined storage units as needed, further enhancing the flexibility and adaptability of the parts box system layout and better meeting the complex and diverse field storage needs.

[0077] In this embodiment, the third connecting part 230 is specifically a plug-in groove with insertion ports at both the top and bottom, and the fourth connecting part 240 is specifically a matching plug-in. The cross-section of the plug-in groove and the plug-in block is a trapezoidal structure. With this structure, when two parts boxes need to be combined laterally, simply align the plug-in block on one side of the parts box and insert it into the plug-in groove on the other side to achieve a horizontal connection between the two parts boxes. Furthermore, this structure has a natural guiding effect, facilitating quick alignment and assembly, effectively limiting the relative displacement between the boxes after connection, ensuring the stability of side-by-side assembly, and preventing accidental detachment during use.

[0078] In this embodiment, the side panel 200 includes a front panel and a peripheral panel that surrounds the front panel to form the wall of the storage compartment.

[0079] The front panel is shorter than the perimeter panel. The perimeter panel has sloping ends, with the shorter end of the sloping end connected to the front panel.

[0080] Specifically, this embodiment has three peripheral panels, which, together with a lower front panel, form a storage compartment. In this structure, the higher peripheral panels provide support and enclosure in three directions, ensuring structural stability and the effective volume of the container. By setting the height of the front panel to be less than that of the peripheral panels, and by incorporating sloping structures at both ends of the peripheral panels that smoothly connect to the lower front panel, a low, unobstructed access opening is created in front of the parts box. This facilitates user observation of the parts inside the box and allows for easy access, improving convenience and efficiency. The sloping structures ensure a smooth transition between the front panel and the higher peripheral panels, optimizing the product's appearance lines, avoiding abrupt steps, and enhancing the overall structural integrity.

[0081] In this embodiment, the side plate 200 has an outer edge 250 at the end away from the storage compartment. The outer edge 250 is located on the side of the side plate 200 away from the storage compartment and extends in a direction away from the storage compartment.

[0082] The outer edge 250 enhances the overall rigidity and structural strength of the side panel 200, making the top of the parts box less prone to warping or breakage when subjected to external impacts or internal loads. Furthermore, the outer edge 250 structure extends horizontally outward from the opening of the storage compartment and then downwards to form a handle, allowing force to be applied when handling the parts box.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
