Description

Technical Field

[0001] This utility model relates to the field of storage basket technology, and more specifically, to a plastic basket with stacking and reinforcing support columns. Background Technology

[0002] Plastic crates are widely used in the storage and transportation of food, fresh produce, and industrial parts due to their lightweight, low cost, and corrosion resistance. In practice, to save space, multiple plastic crates are often stacked for storage or transportation.

[0003] Utility model patent CN216375470U discloses a novel plastic basket, comprising a rectangular frame. Each side of the frame has a downward-facing protrusion on its lower sidewalls. Each protrusion is a hollow, open-top shell, with one open end penetrating the upper sidewall of the frame. The protrusions on opposite sides of the frame are not aligned. A vertical insertion block is connected below each protrusion, and the width of the protrusion is greater than the width of the insertion block. On the two perpendicular sides of the frame, the protrusions have a first groove above the frame edge near the center. On the other two sides, the protrusions have a second groove above the frame edge away from the center. The first and second grooves are identical and both engage with the insertion block. Compared to existing technologies, this utility model has the advantages of a reasonable structure, convenient transportation, and long service life.

[0004] While the aforementioned technical solutions offer advantages, existing plastic crates still have some shortcomings when stacked. Most crates rely solely on their own structural integrity for stacking, lacking dedicated reinforcement and support components, resulting in poor stacking stability. When stacked at a height, uneven stress can easily lead to tilting and collapse, causing damage to goods. Although some plastic crates have simple support structures, their strength is insufficient, and the positioning between upper and lower crates is inaccurate. Under conditions of transportation bumps, stacked plastic crates are prone to relative sliding, further affecting stacking stability. Therefore, we propose a plastic crate with reinforced stacking support columns. Utility Model Content

[0005] The purpose of this invention is to provide a plastic basket with stacking and reinforcing support columns to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic basket with stacking and reinforcing support columns includes a frame body. Rectangular end reinforcement frames are integrally formed at both the upper and lower ends of the frame body. Corner columns are fixedly installed at the four corners of the outer side of the frame body. Both ends of the corner columns are simultaneously fixedly installed on the rectangular end reinforcement frames. Multiple horizontal beams are fixedly installed between two corner columns on the same side. Multiple vertical beams are fixedly installed between the upper and lower side plates of the rectangular end reinforcement frames. The vertical beams and horizontal beams are staggered and form a grid. Multiple positioning protrusions for insertion and positioning are fixedly installed on the bottom surface of the lower rectangular end reinforcement frame. Multiple insertion slots are provided on the top surface of the upper rectangular end reinforcement frame. Multiple top ventilation holes are also provided on the top side of the frame body.

[0008] Preferably, the horizontal beam and the vertical beam are simultaneously fixedly installed on the outer side of the frame, and the plane where the bottom wall of the top heat dissipation hole is located is inclined downward at 45°~60°.

[0009] Preferably, the positioning protrusions on the upper and lower plastic baskets are inserted into the insertion slots, and the size of the positioning protrusions is adapted to the size of the insertion slots;

[0010] This design allows for a more stable stacking of the two plastic crates.

[0011] Preferably, an expanding chamber is provided on the groove wall near the groove opening of the insertion groove, and the expanding chamber is a frustum-shaped chamber that is wider at the top and narrower at the bottom;

[0012] Preferably, a hemispherical end is fixedly installed at the bottom end of the positioning protrusion, and the hemispherical end is hemispherical in shape;

[0013] The above two settings make it easier for the positioning protrusion to be inserted into the insertion slot along the expansion chamber.

[0014] Preferably, a bottom wear-resistant layer is provided on the bottom surface of the rectangular end reinforcement frame located at the bottom, and the bottom wear-resistant layer and the rectangular end reinforcement frame are integrally formed.

[0015] This feature improves the wear resistance of the bottom of the frame, making it less prone to wear.

[0016] Preferably, a plurality of longitudinal beams and a plurality of transverse beams are fixedly installed on the bottom surface of the frame, and the longitudinal beams and the transverse beams are also staggered in a grid pattern, and the ends of the longitudinal beams and the transverse beams are fixedly installed on the frame;

[0017] This feature further strengthens the load-bearing capacity of the frame's bottom.

[0018] Preferably, the frame body has an integrally formed inner mesh-like reinforcing frame, which is a mesh structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model enhances the overall strength of the frame by setting up a rectangular end reinforcement frame, corner columns, horizontal beams and vertical beams. With the cooperation of the positioning protrusion and the insertion groove, the upper and lower plastic baskets are accurately positioned and stacked stably, avoiding tilting and collapse due to uneven force or transportation bumps, thus improving the stacking stability.

[0021] 2. This utility model, by setting an enlarged cavity in the insertion slot and a hemispherical end at the bottom of the positioning protrusion, makes the process of inserting the positioning protrusion into the insertion slot smoother, reduces the difficulty of stacking operations, achieves fast and accurate stacking assembly, and improves operational efficiency.

[0022] 3. This utility model enhances the wear resistance and load-bearing capacity of the bottom of the frame by setting a bottom wear-resistant layer, longitudinal beams, transverse beams and an inner grid-like reinforcing frame, reducing frame wear and deformation, thus extending the service life of the plastic basket. At the same time, the top heat dissipation holes ensure ventilation of the internal items, achieving the effect of balancing durability and practicality. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-5 This utility model provides a technical solution: a plastic basket with stacking and reinforcing support columns, including a frame body 1. Rectangular end reinforcing frames 10 are integrally formed at both the upper and lower ends of the frame body 1. Corner columns 11 are fixedly installed at the four corners of the outer side of the frame body 1. Both ends of the corner columns 11 are simultaneously fixedly installed on the rectangular end reinforcing frames 10. Multiple horizontal beams 13 are fixedly installed between two corner columns 11 located on the same side. Multiple vertical beams 12 are fixedly installed between the upper and lower side panels of the rectangular end reinforcing frames 10, with the vertical beams 12 intersecting the horizontal beams 13. The frame is constructed in a grid pattern. Multiple positioning protrusions 2 for insertion and positioning are fixedly installed on the bottom surface of the rectangular end reinforcement frame 10 located at the bottom. Multiple insertion slots 151 are provided on the top surface of the rectangular end reinforcement frame 10 located at the top. Multiple top heat dissipation holes 14 are also provided at the top side of the frame 1. The multiple structures are interconnected to form a grid-like reinforcement layer, which greatly improves the overall strength of the frame 1. With the insertion of the positioning protrusions 2 and the insertion slots 151, the plastic baskets are evenly stressed when stacked, making them less prone to tilting and collapse. The top heat dissipation holes 14 also ensure internal ventilation.

[0034] In this embodiment, the horizontal beam 13 and the vertical beam 12 are simultaneously fixedly installed on the outer side of the frame 1. The plane where the bottom wall of the top heat dissipation hole 14 is located is inclined downward at 45°~60°, which makes it difficult for external dust and rainwater to enter the interior of the frame 1, while not affecting the heat dissipation effect. The horizontal beam 13 and the vertical beam 12 are fixed on the outside of the frame 1, which enhances the structural stability and avoids occupying internal space.

[0035] Specifically, the positioning protrusions 2 on the upper and lower plastic baskets are inserted into the insertion slots 151. The size of the positioning protrusions 2 is adapted to the size of the insertion slots 151. An expansion chamber 15 is provided on the wall of the insertion slot 151 near the opening. The expansion chamber 15 is a frustum-shaped structure that is wider at the top and narrower at the bottom. A hemispherical end 20 is fixedly installed at the bottom of the positioning protrusions 2. The hemispherical end 20 is hemispherical, which makes the positioning accurate when the upper and lower plastic baskets are stacked. The combination of the expansion chamber 15 and the hemispherical end 20 makes the insertion of the positioning protrusions 2 smoother, reduces the difficulty of alignment when stacking, and improves the convenience of operation.

[0036] like Figure 3 As shown, a bottom wear-resistant layer 16 is provided on the bottom surface of the rectangular end reinforcement frame 10 located at the bottom. The bottom wear-resistant layer 16 and the rectangular end reinforcement frame 10 are integrally molded, which enhances the wear resistance of the bottom of the frame 1 and extends its service life. The bottom wear-resistant layer 16 can be made of high-density polyethylene, which has high hardness and wear resistance. When integrally molded with the rectangular end reinforcement frame 10, it can be tightly bonded and is not easy to fall off, which can effectively improve the wear resistance of the bottom of the frame 1 and extend the service life of the plastic basket.

[0037] like Figure 3 As shown, multiple longitudinal beams 17 and multiple transverse beams 18 are fixedly installed on the bottom surface of the frame 1. The longitudinal beams 17 and transverse beams 18 are also interlaced in a grid pattern. The ends of the longitudinal beams 17 and transverse beams 18 are fixedly installed on the frame 1, which further enhances the bottom load-bearing capacity and makes the frame 1 less prone to deformation when loaded with heavy objects.

[0038] like Figure 5 As shown, the frame 1 has an integrally formed inner mesh reinforcement frame 3. The inner mesh reinforcement frame 3 has a mesh structure, which enhances the structural strength of the frame 1 from the inside, making the frame 1 less prone to damage when subjected to external pressure, improving overall durability, and better protecting the items stored inside.

[0039] When using the plastic basket with stacking reinforcement support columns of this utility model, the items are placed inside the frame 1. The inner grid-like reinforcement frame 3 strengthens the frame 1 from the inside and protects the items. The grid structure formed by the horizontal beam 13 and the vertical beam 12, as well as the corner columns 11 and the rectangular end reinforcement frame 10, ensure that the frame 1 does not deform when bearing the load. The top heat dissipation hole 14 ensures internal ventilation, and its sloping bottom wall prevents dust and rainwater from entering.

[0040] When stacking, align the positioning protrusion 2 at the bottom of the upper plastic basket with the insertion slot 151 of the lower plastic basket, and insert the hemispherical end 20 along the expansion chamber 15 to make the upper and lower baskets accurately connected; the bottom wear-resistant layer 16 reduces the friction loss between the frame 1 and the ground, and the longitudinal beam 17 and transverse beam 18 enhance the bottom load-bearing capacity to ensure stacking stability.

[0041] After use, the stacked plastic crates can be disassembled and the inside cleaned.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
