Description

Technical Field

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

[0002] EPS foam is a lightweight porous polymer. It is manufactured by adding a foaming agent to polystyrene resin and heating it to create a closed honeycomb structure containing air bubbles.

[0003] A search of Chinese patent publication number CN212290811U reveals an EPS foam packaging structure.

[0004] In the above technical solution: a base plate with an annular slot, a folding component inserted into the annular slot, and four symmetrical rubber strips on the folding component. The folding component folds and unfolds by bending the rubber strips. After unfolding, the folding component inserts into the annular slot to form the four walls of the foam packaging box. The rubber strips are reinforced by insert connectors. This utility model can fold the four walls of the foam packaging box into a flat structure by forming a bent part with the rubber strips. It can be stacked, stored, and transported together with the base plate. When in use, it can be quickly assembled to form a sturdy foam packaging structure. The use and storage process is relatively simple.

[0005] However, the above-mentioned solution can only encapsulate items of a fixed size and cannot be changed according to the size of the packaged item, which limits its application.

[0006] Therefore, we propose an EPS foam packaging structure. Utility Model Content

[0007] The present invention aims to solve the technical problems existing in the prior art and provide an EPS foam packaging structure.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: an EPS foam packaging structure, including a chassis assembly, side plate assemblies slidably connected to both sides of the chassis assembly, and insert plate assemblies inserted into the other two sides of the chassis assembly. The insert plate assemblies engage with the chassis assembly and the side plate assemblies. The chassis assembly includes a base plate, with two elongated grooves symmetrically formed on the upper surface of the base plate. A plurality of first toothed blocks are arranged in an array inside the elongated grooves. Sliding grooves are formed on both sides of the base plate, and the sliding grooves communicate with the elongated grooves. Two side plate assemblies are symmetrically arranged. Each side plate assembly includes a limiting block slidably connected in a sliding groove. Several second toothed blocks are arrayed on the side of the limiting block near the sliding groove. Two connecting rods are fixedly connected to one side of the limiting block. The two connecting rods are arranged on both sides of the sliding groove. A side plate is fixedly connected to one end of each connecting rod. Sliding grooves for inserting plate assemblies are symmetrically opened on the side plate. Each plate assembly includes a sealing plate. A toothed plate is provided at the lower end of the sealing plate. A slider is fixedly connected to one side of the sealing plate. Several plate assemblies are provided that can be inserted into each other.

[0009] This utility model provides an EPS foam packaging structure, which has the following improvements and advantages compared with the prior art:

[0010] (1) This utility model uses a toothed plate and a first toothed block and a second toothed block to mesh, and a limiting block is set to slide in the sliding groove. Several first toothed blocks are arranged in an array on the inner side of the long groove. The slider is inserted into the sliding groove. By sliding the limiting block, the length of the side plate is adjusted. Then, the insert plate assembly is used to fix it. It can package objects with a longer length, has a wider range of applications, and is more practical. Attached Figure Description

[0019] Example

[0020] Please see Figures 1 to 4 Embodiment 1 includes a chassis assembly 10, with side plate assemblies 20 slidably connected to both sides of the chassis assembly 10. The length of the slidably connected side plate assemblies 20 is adjustable. Insert plate assemblies 30 are inserted into the other two sides of the chassis assembly 10. The insert plate assemblies 30 and the side plate assemblies 20 form four walls. The insert plate assemblies 30 engage with the chassis assembly 10 and the side plate assemblies 20. The insert plate assemblies 30 fix the side plate assemblies 20 through the chassis assembly 10. The insertion of the insert plate assemblies 30 and the side plate assemblies 20 forms a stable four-wall structure. The chassis assembly 10 includes a base plate 11. Two elongated slots 12 are symmetrically formed on the upper surface of the base plate 11. Several first toothed blocks 13 are arrayed inside the elongated slots 12. The base plate 11 serves as the foundation, the elongated slots 12 provide sliding space, and the first toothed blocks 13 provide a fixing function. Sliding grooves 14 are formed on both sides of the base plate 11. The sliding grooves 14 are used to place limiting blocks 22 and are connected to the elongated slots 12. Two side plate assemblies 20 are symmetrically arranged, allowing for lateral movement. The side plate assemblies 20 include sliding connecting... The limiting block 22 is connected to the sliding groove 14. When the limiting block 22 engages with the insert plate assembly 30, it is fixed. Several second tooth blocks 23 are arranged in an array on the side of the limiting block 22 near the sliding groove 14. The second tooth blocks 23 are the components used for engagement. Two connecting rods 24 are fixedly connected to one side of the limiting block 22. The connecting rods 24 are used to connect the side plate 21. The two connecting rods 24 are arranged on both sides of the sliding groove 14. One end of the connecting rod 24 is fixedly connected to the side plate 21. Insertion plate assemblies are symmetrically opened on the side plate 21. The slide groove 25 of component 30 is used to stabilize the connection with the insert plate assembly 30. The insert plate assembly 30 includes a sealing plate 31. A toothed plate 32 is provided at the lower end of the sealing plate 31. The toothed plate 32 meshes with the first toothed block 13 and the second toothed block 23. A slider 33 is fixedly connected to one side of the sealing plate 31.
