Description

Technical Field

[0001] This utility model relates to the field of plastic box technology, and more specifically, to a plastic box with anti-deformation function. Background Technology

[0002] Plastic boxes are transparent folding boxes, cylinders, hinged boxes, tote bags, hanging tags, and other related plastic products made of materials such as PVC / PET / PP / PS. After adding various additives, these materials become plastic under certain temperature and pressure conditions, and can be fixed in shape after cooling. The process of natural or synthetic polymer resin molecules being in a molten state with additive molecules evenly distributed around them is called plasticization. Common food plastic boxes include disposable lunch boxes, takeout boxes, food preservation boxes, and snack storage containers.

[0003] Traditional plastic boxes use a single-layer plastic design. Since the items inside are generally smaller than the internal dimensions of the box, they tend to shake and impact the inner walls during movement, potentially causing damage. Furthermore, traditional single-layer plastic boxes lack structural strength, are easily deformed under pressure, and have limited functionality. Further improvements are warranted.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic box with anti-deformation function, which has the advantages of improved anti-deformation ability and enriched usage functions, thereby solving the problems mentioned in the background technology.

[0006] To achieve the aforementioned advantages of improved deformation resistance and enhanced functionality, the specific technical solution adopted by this utility model is as follows:

[0007] A plastic box with anti-deformation function includes a box body and a box lid. The box lid is hinged to the top surface of the box body. Both the box body and the box lid are hollow structures. A third reinforcing rib and a fourth reinforcing rib are fixedly installed inside the box body. A first reinforcing rib and a second reinforcing rib are fixedly installed inside the box lid. A side groove is formed on the inner wall of the box body. A slider is slidably connected inside the side groove. A support plate is fixedly connected between the sliders. A handle bolt is threaded through the surface of the slider, and one end of the handle bolt abuts against the inner wall of the side groove.

[0008] Furthermore, the first and second reinforcing ribs are arranged vertically in both directions, and both the first and second reinforcing ribs are groove-shaped structures.

[0009] Furthermore, the third and fourth reinforcing ribs are arranged vertically in both directions, and both the third and fourth reinforcing ribs are groove-shaped structures.

[0010] Furthermore, the other end of the box body and the box lid are fixedly connected by spring locks, and multiple sets of spring locks are arranged.

[0011] Furthermore, the box body and the box cover are made of the same material, and the box body, the slider and the support clamp are made of the same material, and there are two sets of support clamps.

[0012] Furthermore, the first, second, third, and fourth reinforcing ribs are made of the same material as the box body, and the first, second, third, and fourth reinforcing ribs have the same thickness, and the thickness of the first, second, third, and fourth reinforcing ribs is not less than 2mm.

[0013] Furthermore, the vertical cross-sectional shape of the side groove is trapezoidal, and the size of the side groove is adapted to the size of the slider.

[0014] Furthermore, a handle is hinged to the top surface of the lid.

[0015] Compared with the prior art, this utility model provides a plastic box with anti-deformation function, which has the following beneficial effects:

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a plastic box with anti-deformation function is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a plastic box with anti-deformation function according to an embodiment of the present invention includes a box body 1 and a box lid 2. The box lid 2 is hinged to the top surface of the box body 1 by a hinge 12. Both the box body 1 and the box lid 2 are hollow structures. A third reinforcing rib 5 and a fourth reinforcing rib 6 are fixedly installed inside the box body 1. A first reinforcing rib 3 and a second reinforcing rib 4 are fixedly installed inside the box lid 2. A side groove 7 is provided on the inner wall of the box body 1. A slider 8 is slidably connected inside the side groove 7. A support clamp 10 is fixedly connected between the sliders 8. A handle bolt 9 is threaded through the surface of the slider 8, and one end of the handle bolt 9 abuts against the inner wall of the side groove 7. The box body 1 and the box lid 2 are made of the same material. The box body 1, the slider 8, and the support clamp 10 are made of the same material. Two sets of support clamps 10 are arranged. The support plates 10 are fixedly connected at both ends to sliders 8 that slide inside the side grooves 7. Users can place the items to be fixed between the support plates 10, then loosen the handle bolts 9, move the support plates 10 to clamp the items, and then tighten the handle bolts 9 to fix the items. This prevents the items from hitting the inner wall of the box 1 and causing damage during movement, and facilitates the protection of items that need to be stably stored. This enriches the functionality. At the same time, the position of the support plates 10 is adjustable, making them suitable for items of various sizes, thus expanding their range of applications and making them more versatile. In addition, the top and bottom surfaces of the support plates 10 abut against the inner bottom surface of the box 1 and the inner top surface of the lid 2, respectively, providing internal support, improving the overall compressive strength, enhancing the resistance to deformation, and improving the stability of the structure.

[0028] In one embodiment, the first reinforcing rib 3 and the second reinforcing rib 4 are arranged vertically in both directions, and both the first reinforcing rib 3 and the second reinforcing rib 4 are groove-shaped structures. The third reinforcing rib 5 and the fourth reinforcing rib 6 are also arranged vertically in both directions, and both the third reinforcing rib 5 and the fourth reinforcing rib 6 are groove-shaped structures. These arrangement of the first reinforcing rib 3 and the second reinforcing rib 4, with their groove-shaped structures, serve to internally support the lid 2, reducing the pressure deformation of the lid 2. Similarly, the third reinforcing rib 5 and the fourth reinforcing rib 6 serve to internally support the box body 1, reducing the pressure deformation of the box body 1. This significantly improves the overall pressure resistance and deformation prevention capabilities. Furthermore, since both the box body 1 and the lid 2 have hollow interiors, they provide a certain degree of insulation, further enriching the functionality.

[0029] In one embodiment, the other end of the box body 1 and the box cover 2 are fixedly connected by spring latches 13, and multiple sets of spring latches 13 are arranged, which is a common installation structure and will not be described in detail here.

[0030] In one embodiment, the first reinforcing rib 3, the second reinforcing rib 4, the third reinforcing rib 5, and the fourth reinforcing rib 6 are made of the same material as the box body 1, which facilitates production. The first reinforcing rib 3, the second reinforcing rib 4, the third reinforcing rib 5, and the fourth reinforcing rib 6 have the same thickness, and the thickness of the first reinforcing rib 3, the second reinforcing rib 4, the third reinforcing rib 5, and the fourth reinforcing rib 6 is not less than 2mm, which improves the stability of the support.

[0031] In one embodiment, the vertical cross-sectional shape of the side groove 7 is trapezoidal, and the size of the side groove 7 is adapted to the size of the slider 8 to prevent the slider 8 from detaching from the side groove 7.

[0032] In one embodiment, a handle 11 is hinged to the top surface of the lid 2 for easy carrying.

[0033] Working principle:

[0034] The support clamp 10 has sliders 8 fixedly connected to both ends, which slide inside the side groove 7. Users can place the items to be secured between the support clamps 10, then loosen the handle bolt 9, move the support clamp 10 to clamp the items, and then tighten the handle bolt 9 to secure the items. This prevents damage caused by items hitting the inner wall of the box 1 during movement, thus protecting items that need stable storage and enriching its functionality. Furthermore, the support clamp 10 is adjustable, suitable for items of various sizes, broadening its application range and making its use more diverse. Additionally, the top and bottom surfaces of the support clamp 10 abut against the inner bottom surface of the box 1 and the inner top surface of the lid 2, respectively. The first and second reinforcing ribs 3 and 4 are arranged vertically in both directions and are channel-shaped structures, serving as internal supports for the lid 2 and reducing the deformation of the lid 2 under pressure. Similarly, the third and fourth reinforcing ribs 5 and 6 serve as internal supports for the box body 1, reducing the deformation of the box body 1 under pressure, significantly improving the overall compressive strength and deformation resistance. Furthermore, since both the box body 1 and the lid 2 have hollow interiors, they also provide insulation to a certain extent, further enriching the functionality.
