Description

Technical Field

[0001] This utility model relates to the field of electronic product packaging box technology, and in particular to a multi-layer pressure-resistant electronic product packaging box. Background Technology

[0002] To maximize space utilization during transportation or storage and to protect electronic products, they are typically stacked inside packaging boxes.

[0003] Furthermore, when storing electronic products, existing packaging boxes are usually not completely filled to avoid external pressure being transmitted to the product through the packaging box. The pressure is entirely borne by the packaging box itself. When stacked, the packaging box has limited pressure-bearing capacity. If the pressure is too great, the packaging box will be crushed and collapse, resulting in damage to the contents. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a multi-layer pressure-resistant electronic product packaging box, solving the problem that the packaging box cannot withstand excessive pressure and is thus crushed.

[0005] The technical solution of this utility model is as follows: a multi-layer pressure-resistant electronic product packaging box, including an outer box body, an inner liner inside the outer box body, the inner liner being a cylindrical structure with four flat plates and openings at the top and bottom, tongues being symmetrically punched on the surface of the inner liner, the tongues being bent and protruding to opposite sides to form a triangular truncated pyramid, a lower support plate being provided at the bottom of the triangular truncated pyramid, and an upper support plate being provided at the top of the triangular truncated pyramid.

[0006] Furthermore, the free end of the tongue is bent to form a limiting piece.

[0007] Furthermore, the limiting piece is inserted and pasted between the outer casing and the inner liner. The limiting piece can fix the bending angle of the tongue and prevent the tongue from moving.

[0008] Furthermore, a through groove is stamped on the surface of the outer casing, and the limiting piece passes through the through groove and is attached to the outer casing.

[0009] Furthermore, the limiting piece at the free end of the tongue is divided into three equal sections, with the upper and lower sections inserted between the inner liner and the outer housing, and the middle section bent outward along the through groove on the surface of the outer housing and adhered to the surface of the outer housing.

[0010] Furthermore, the triangular truncated pyramid is positioned on two opposite sides of the inner bushing.

[0011] Furthermore, the triangular truncated pyramid is disposed on four surfaces inside the inner bushing.

[0012] Furthermore, the triangular truncated pyramid is positioned at two opposite corners of the inner bushing.

[0013] Furthermore, the triangular truncated pyramid is positioned at the four apex corners of the inner bushing.

[0014] Furthermore, the bottom of the upper support plate is provided with a lug, which is inserted between the inner side of the triangular truncated pyramid and the inner bushing to ensure that the upper support plate will not change position and to fix the position of the upper support plate.

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

[0016] 1. This utility model provides a buffer between the electronic product and the outer casing by setting an inner liner inside the outer casing. At the same time, a protruding triangular truncated pyramid is set on the surface of the inner liner. The triangular truncated pyramid has a certain supporting force in the vertical direction. The upper and lower ends of the triangular truncated pyramid contact the lower support plate and the upper support plate, respectively. When the outer casing is closed and receives pressure, the pressure is transmitted to the triangular truncated pyramid through the upper support plate. The triangular truncated pyramid then presses down on the lower support plate, and the pressure is transmitted downward through the lower support plate pressing down on the bottom of the outer casing. This concentrates the pressure on the triangular truncated pyramid when the outer casing is under pressure, preventing the outer casing itself from deforming or even collapsing due to pressure.

[0017] 2. This utility model can adapt the storage space inside the outer casing to accommodate electronic products by changing the position of the tripod, thus avoiding the tripod from encroaching on the storage space, and the tripod in different positions can still maintain its pressure resistance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1, such as Figure 1-3 As shown, a multi-layer pressure-resistant electronic product packaging box includes an outer box body 1, and an inner liner 2 is provided inside the outer box body 1. The inner liner 2 is a cylindrical structure with four flat plates and openings at the top and bottom. The inner liner 2 is characterized in that: the surface of the inner liner 2 is symmetrically punched to form tongues 3, the tongues 3 are bent and protruded to opposite sides to form triangular truncated pyramids 31, the triangular truncated pyramids 31 are provided on two opposite sides of the inner liner 2, a lower support plate 4 is provided at the bottom of the triangular truncated pyramids 31, an upper support plate 5 is provided at the top of the triangular truncated pyramids 31, and an insert is provided at the bottom of the upper support plate 5. The insert is inserted between the inner side 1 of the triangular truncated pyramids 31 and the inner liner 2 to ensure that the upper support plate 5 will not change position and to fix the position of the upper support plate 5.

[0029] The free end of the tongue 3 is bent to form a limiting piece 6. The limiting piece 6 is inserted and pasted between the outer box 1 and the inner bushing 2. The bending angle of the tongue 3 can be fixed by the limiting piece 6 to prevent the tongue 3 from moving. A through groove is stamped on the surface of the outer box 1. The limiting piece 6 passes through the through groove and is pasted to the outer box 1.

[0030] The working principle of this utility model is as follows: First, when using it, the operator places the lower support plate 4 inside the outer box 1, then inserts the inner liner 2 into the outer box 1 and puts it on the outside of the lower support plate 4. Then, the operator unfolds the triangular platform 31 through the tongue 3 and fixes the position of the limiting piece 6. At this time, the operator can place the electronic product inside the outer box 1. After the product is placed, the upper support plate 5 is placed on the top of the triangular platform 31 and the outer box 1 is closed.

[0031] When the outer casing 1 is stacked, the pressure is transmitted through the outer casing 1 to the upper support plate 5. The upper support plate 5 presses down on the triangular platform 31, and the triangular platform 31 supports the upper support plate 5 while transmitting the pressure downward. The pressure is transmitted downward through the lower support plate 4 and the outer casing 1. At this time, the main pressure-bearing part of the outer casing 1 is the triangular platform 31, while the outer casing 1 itself can remain intact.

[0032] Example 2, as Figure 4 As shown, the only difference from Embodiment 1 is that a through groove is stamped on the surface of the outer casing 1, and the limiting piece 6 passes through the through groove and is pasted to the outer casing 1.

[0033] Example 3, as Figure 5As shown, the only difference from embodiments 1 and 2 is that a through groove is stamped on the surface of the outer casing 1, and the limiting piece 6 passes through the through groove and is pasted to the outer casing 1. The limiting piece 6 is divided into three equal parts, with the upper and lower parts inserted between the inner bushing 2 and the outer casing 1, and the middle part bent outward along the through groove on the surface of the outer casing 1 and adhered to the surface of the outer casing 1.

[0034] Example 4, as Figure 6 As shown, the only difference from embodiments 1, 2, and 3 is that the tripod 31 is set on the four surfaces inside the inner bushing 2, which reduces the internal space of the outer casing 1 to accommodate different electronic products while increasing the number of tripods 31 to enhance the overall structure's pressure resistance.

[0035] Example 5, as Figure 7 As shown, the only difference from embodiments 1, 2, 3, and 4 is that the triangular truss 31 is set at two opposite corners of the inner bushing 2.

[0036] Example 6, as Figure 8 As shown, the only difference from embodiments 1, 2, 3, 4, and 5 is that the triangular truncated pyramid 31 is located at the four apex positions of the inner bushing 2.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
