Description

Technical Field

[0001] This utility model relates to the field of foam packaging technology, and in particular to a foam packaging positioning structure. Background Technology

[0002] Foam packaging is a type of packaging made primarily of foam plastic. Through its unique physical structure, it provides cushioning and protection for products and is widely used in transportation.

[0003] Fragile items, such as water cups, need to be placed in foam packaging for transportation. However, in actual use, because the sizes of foam packaging are not consistent, gaps may exist between the foam packaging during storage, making it impossible to securely position them. During transportation, the foam packaging may fall off and damage the contents. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foam packaging positioning structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foam packaging positioning structure includes a protective box and a foam packaging body. The foam packaging body is placed inside the protective box, and a positioning cover is fitted on the top of the foam packaging body. Limiting plates are rotatably installed on all four sides of the inner wall of the protective box. Flexible pads are attached to the contact side of the limiting plates. Two springs are installed on one side of the lower end of the limiting plates, and the other end of the springs is connected to the side of the inner wall of the protective box with grooves.

[0007] Furthermore, a preferred structure is that rotating grooves are provided on both sides of the upper end of the groove.

[0008] In addition, a preferred structure is that the upper end of the limiting plate is provided with a rotating shaft on both sides, and the rotating shaft rotates within the rotating groove.

[0009] In addition, a preferred structure is that the inner wall of the protective box has grooves on all four sides.

[0010] In addition, a preferred structure is that limiting blocks are provided on all four sides of the outer wall of the positioning cover, and the limiting blocks slide within the groove.

[0011] In addition, a preferred structure is that positioning plates are installed on all four sides of the inner wall of the positioning cover via second spring telescopic columns, and the lower end of the positioning plate is arc-shaped.

[0012] In addition, a preferred structure is that the top of the protective box is connected to the top cover by a snap fastener, and the bottom of the top cover is mounted on the top plate by two first spring telescopic columns, with the top plate in contact with the positioning cover.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, foam packaging of different sizes is placed inside a protective box. The foam packaging is positioned inside the protective box by the positioning action of the limiting plate, positioning cover, and top plate. The protective boxes can be stacked together and will not easily fall off when bumped during transportation, thus protecting the safety of the contents inside the foam packaging.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1-7 A foam packaging positioning structure includes a protective box 1 and a foam packaging body 3. The foam packaging body 3 is placed inside the protective box 1. A positioning cover 4 is fitted on the top of the foam packaging body 3. Limiting plates 5 are rotatably installed on all four sides of the inner wall of the protective box 1. Flexible pads 52 are attached to the contact side of the limiting plates 5. Two springs 6 are installed on one side of the lower end of the limiting plates 5. The other end of the springs 6 is connected to one side of the groove 11 on the four sides of the inner wall of the protective box 1.

[0025] The groove 11 has a rotating groove 111 on both sides of its upper end, and the limiting plate 5 has a rotating shaft 51 on both sides of its upper end. The rotating shaft 51 rotates within the rotating groove 111.

[0026] Furthermore, the inner wall of the protective box 1 has four sliding grooves 12 on all four sides, and the outer wall of the positioning cover 4 has four limiting blocks 41 on all four sides. The limiting blocks 41 slide within the sliding grooves 12, making it easy for the positioning cover 4 to be fitted onto the top of the foam packaging body 3.

[0027] Meanwhile, positioning plates 10 are installed on all four sides of the inner wall of the positioning cover 4 via second spring telescopic columns 9. The lower end of the positioning plate 10 is arc-shaped, which facilitates the movement of the positioning plate 10 when the top of the foam packaging body 3 is squeezed, thereby limiting the top of the foam packaging body 3.

[0028] Furthermore, the top of the protective box 1 is connected to the top cover 2 by a snap fastener, and the bottom of the top cover 2 is fitted with a top plate 8 by two first spring telescopic columns 7. The top plate 8 is in contact with the positioning cover 4, and the top plate 8 presses down and limits the positioning cover 4 under the action of the first spring telescopic columns 7.

[0029] In this embodiment, fragile items are placed in foam packaging 3 for packaging, and then foam packaging 3 is vertically inserted into protective box 1. The lower end of foam packaging 3 presses against limiting plate 5. Limiting plate 5 rotates around rotating shaft 51 and then presses spring 6. At this time, the lower end of foam packaging 3 is limited and positioned by four limiting plates 5.

[0030] Next, the limiting block 41 of the positioning cover 4 is slidably inserted into the slide groove 12 and put on the top of the foam packaging body 3. The top of the foam packaging body 3 squeezes the positioning plate 10 and moves, while the top of the foam packaging body 3 is limited and positioned by the positioning plate 10.

[0031] Next, the top cover 2 is snapped onto the protective box 1 with a buckle. The first spring telescopic column 7 retracts, and the top plate 8 presses down the positioning cover 4 to limit its position. At this time, the foam packaging body 3 is positioned and placed inside the protective box 1. The protective boxes 1 are stacked in an orderly manner so that they will not easily fall off during transportation.

[0032] In this invention, foam packaging bodies 3 of different sizes are placed inside protective boxes 1. The foam packaging bodies 3 are positioned inside protective boxes 1 under the positioning action of limiting plate 5, positioning cover 4, and top plate 8. Protective boxes 1 can be stacked together and will not easily fall off when bumped during transportation, thus protecting the safety of the contents inside the foam packaging bodies 3.

[0033] 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.
