Description

Technical Field

[0001] The utility model belongs to the technical field of plastic boxes and relates to a rotatable and stackable plastic box. Background Art

[0002] Plastic crates are resistant to bending, aging, stretching, compression, tearing, and high temperatures. They can be used as packaging boxes for both turnover and finished product shipments. They are lightweight, durable, and stackable. Customizable in various sizes and specifications, they can be fitted with lids, are dust-proof, anti-static, and aesthetically pleasing. Anti-static crates are typically designed and manufactured to customer-provided dimensions for optimal loading. Multiple crates can be stacked, effectively utilizing factory space, increasing storage capacity for electronic components, PCBs, and cleanroom parts, and reducing production costs. However, existing plastic crates still have some drawbacks. When stacked, two adjacent crates are nested together, resulting in tight contact between the crates during removal, making it difficult to separate them. Furthermore, they cannot be stacked when filled, which not only takes up space but also easily causes the crates to tip over, resulting in unnecessary losses. Utility Model Content

[0003] The purpose of this utility model is to provide a rotatable and stackable plastic box in view of the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The outside of the plastic box body 1 is inwardly recessed and provided with two groups of first mounting grooves 7 and two groups of second mounting grooves 8, wherein the first mounting groove 7 is provided on the two edges of the plastic box body 1, and the first mounting groove 7 is provided on the two edges of the plastic box body 1. On the same side of the plastic box body 1, the first mounting groove 7 is a semicircular arc structure, and the arc radius of the first mounting groove 7 gradually increases from top to bottom, the first mounting groove 7 is recessed inwardly to form a first protrusion 9 inside the plastic box body 1, and the second mounting groove 8 is located on the same side of the plastic box body 1, the second mounting groove 8 is a semicircular arc structure, and the arc radius of the second mounting groove 8 gradually increases from top to bottom, the second mounting groove 8 is recessed inwardly to form a second protrusion 10 inside the plastic box body 1, and the opening area of the structure of the plastic box body 1 gradually decreases from top to bottom.

[0029] In this embodiment, when there is nothing inside the plastic box, the plastic box needs to be stored. At this time, it is only necessary to nest each adjacent plastic box together, and the first mounting groove 7 and the second mounting groove 8 of the upper plastic box respectively cooperate with the first protrusion 9 and the second protrusion 10 below, so that the plastic boxes can be stacked stably.

[0030] Combine Figure 2 As shown, a quadrilateral reinforcement grid 11 is provided on the lower surface of the base 2 .

[0031] In this embodiment, the quadrilateral reinforcement grid 11 can improve the strength of the plastic box, so that the plastic box can carry heavier items.

[0032] Combine Figure 3 、 Figure 4 As shown, the inner side of the folding structure 4 is fixedly connected to the side wall 3 of the plastic box body 1 through reinforcing ribs.

[0033] In this embodiment, reinforcing ribs are provided on the inner side of the folding structure 4 to improve the strength of the folding structure 4, thereby improving the overall strength of the plastic box.

[0034] Combine Figure 2 As shown, a cylindrical support column 12 is integrally formed at the center position below the base 2 , and the height of the cylindrical support column 12 is the same as that of the support leg 5 .

[0035] In this embodiment, the cylindrical support column 12 can support the middle part of the plastic box, thereby improving the bearing capacity of the plastic box.

[0036] Combine Figure 3 、 Figure 4 As shown, a rib clamping position 13 is provided on the outer side of the first installation groove 7 and the second installation groove 8 and extends downward from the folding structure 4. The rib clamping position 13 is a double-layer structure.

[0037] In this embodiment, the rib clamping position 13 is used to limit the position between adjacent plastic boxes, so that a suitable distance is maintained between two adjacent plastic boxes for easy removal.

[0038] Combine Figure 5 、 Figure 6 As shown, a first step 14 is formed above the first protrusion 9 , and a first locking groove 15 is provided on the first step 14 .

[0039] Combine Figure 5 、 Figure 6 As shown, a second step 16 is formed above the second protrusion 10 , and a second slot 18 is provided on the second step 16 .

[0040] In this embodiment, when empty boxes are stacked, the rib positions 13 fall into the adjacent first slots 15 and second slots 18 respectively; when loaded, the legs 5 fall into the first slots 15 and second slots 18 respectively.

[0041] Combine Figure 7 、 Figure 8 As shown, the first mounting groove 7 and the second mounting groove 8 have the same shape and size.

[0042] Combine Figure 2 、 Figure 3 As shown, the side wall 3 of the plastic box body 1 is recessed inwardly to form a stepped groove 17 .

[0043] In this embodiment, the stepped groove 17 can improve the strength of the box body and play a role in positioning when stacking.

[0044] Combine Figure 2 、 Figure 8 As shown, the bottoms of the first mounting groove 7 and the second mounting groove 8 both extend to the support leg 5 , and the interior of the support leg 5 is a hollow structure with reinforcing ribs provided therein.

[0045] In this embodiment, when there is something inside the plastic box, the plastic box can be rotated 180° and stacked. After rotating 180°, the support legs 5 of the upper box body just fall on the first protrusion 9 and the second protrusion 10, and the support legs 5 fall into the first slot 15 and the second slot 18.

[0046] The working principle of this utility model is:

[0047] The utility model is provided with two groups of first mounting grooves 7 and two groups of second mounting grooves 8 on the outside of the plastic box body 1. When there is nothing inside the plastic box, the plastic box needs to be stored. At this time, it is only necessary to nest each adjacent plastic box together, and the first mounting groove 7 and the second mounting groove 8 of the upper plastic box respectively cooperate with the first protrusion 9 and the second protrusion 10 below, so that the plastic boxes can be stacked stably. Since the outer sides of the first mounting groove 7 and the second mounting groove 8 are downwardly extended by the folding structure 4 with a rib clamping position 13, when the empty plastic boxes are stacked, the rib clamping position 13 can be just clamped in the first clamping groove 15 and the second clamping groove 18 below, thereby ensuring the stability of the stacking and keeping a suitable distance between the two adjacent plastic boxes for easy picking.

[0048] When the plastic box is filled with things, the plastic box can be rotated 180 degrees and stacked. After rotating 180 degrees, the legs 5 of the upper box body just fall on the first protrusion 9 and the second protrusion 10, and the legs 5 fall into the first card slot 15 and the second card slot 18, thereby providing two usage modes. When the box is empty, it can be better stored. When the plastic box is filled with things, it can be stacked. At the same time, the plastic box has high strength, stable stacking, and is not easy to tip over. It has the advantages of simple structure, easy use, and good use effect.

[0049] The specific embodiments described herein are merely examples of the spirit of the present invention.
