Description

A foldable EPS foam board Technical Field

[0001] This utility model relates to the field of EPS foam board technology, and in particular to a foldable EPS foam board. Background Technology

[0002] EPS foam boards are widely used in building insulation and packaging cushioning due to their advantages such as light weight, good thermal insulation performance, and low cost. However, existing EPS foam boards have some obvious shortcomings in practical use.

[0003] Insufficient Strength: Traditional EPS foam boards have a simple internal structure, typically consisting only of EPS foam material, lacking effective reinforcement. This makes them prone to deformation and damage when subjected to external pressure or impact. In building insulation projects, prolonged exposure to wind and sun, building settlement, and other external forces can cause cracks in the foam boards, affecting insulation performance and potentially requiring replacement, increasing costs. During packaging and transportation, if subjected to significant impacts, the foam boards cannot provide sufficient protection for the contents, leading to damage.

[0004] Poor flexibility in use: Most EPS foam boards come in fixed shapes and sizes, making it difficult to adjust the angle or fold them according to the needs of actual use scenarios. In some special architectural spaces, such as irregular corners or curved walls, fixed-shaped foam boards cannot fit well, resulting in poor insulation performance and material waste. In terms of transportation and storage, because they cannot be folded, they occupy a lot of space, increasing transportation costs, and storage is inconvenient, requiring a large storage space.

[0005] To address the problems existing in the prior art, this utility model proposes a foldable EPS foam board. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable EPS foam board.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A foldable EPS foam board includes a rotating shaft and two EPS foam board bodies. Each EPS foam board body has an internal skeleton, which includes a first reinforcing rod and a second reinforcing rod. The second reinforcing rod passes through the first reinforcing rod. One end of the first reinforcing rod on one EPS foam board body is threadedly connected to a first stud, and one end of the first reinforcing rod on the other EPS foam board body is threadedly connected to a second stud. One end of the first stud is fixed to a first connecting seat, which has a spline hole. One end of the second stud is fixed to a second connecting seat, which has a sliding hole. The rotating shaft has a spline groove that matches the spline hole. The rotating shaft is slidably fitted into the first connecting seat through the spline hole and spline groove. The rotating shaft is located within the sliding hole of the second connecting seat. A limiting component for limiting the rotation of the rotating shaft is installed on the second connecting seat.

[0009] Preferably, a limiting block is fixedly sleeved on the first stud.

[0010] Preferably, the limiting component includes a positioning groove, a fixed seat, a positioning insert, and a spring. The fixed seat is fixed on the second connecting seat, and a sliding groove is provided on the fixed seat. The positioning insert is slidably sleeved in the sliding groove, and a spring is connected between the sliding groove and the positioning insert. The rotating shaft is provided with positioning grooves arranged in a circumferential array, and the positioning grooves match the positioning inserts.

[0011] Preferably, a sliding rod is fixed on the positioning insert, and the sliding rod slides through the fixing seat and is fixed with a lever.

[0012] Preferably, one end of the rotating shaft is threaded with a nut, and the other end of the rotating shaft is fixed with a stop.

[0013] Preferably, the skeleton is arranged in a grid pattern.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by setting a grid-like skeleton inside the EPS foam board body, the strength of the EPS foam board body can be greatly enhanced while meeting the performance requirements of the EPS foam board body.

[0016] 2. In this utility model, the first stud and the second stud are respectively connected to the first reinforcing rod on different EPS foam board bodies by threads, which facilitates disassembly and assembly. The rotating shaft is inserted into the spline hole on the first connecting seat and the sliding hole on the second connecting seat. The spline groove on the rotating shaft is connected with the spline hole. In this way, the rotating shaft cannot rotate in the first connecting seat but can rotate in the second connecting seat. Thus, the two EPS foam board bodies can rotate relative to each other. After rotating to the appropriate position, the rotating shaft can be limited by the limiting component. Since the rotating shaft itself cannot rotate in the first connecting seat, it also cannot rotate relative to the second connecting seat. Therefore, the two EPS foam board bodies are stabilized in the rotated position and can rotate at the required angle. The overall structure is stable, and the disassembly and assembly of the two EPS foam board bodies are also very convenient. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Referring to Figures 1-4, a foldable EPS foam board includes a rotating shaft 2 and two EPS foam board bodies 1. Each EPS foam board body 1 has an internal skeleton arranged in a grid pattern. The skeleton includes a first reinforcing rod 4 and a second reinforcing rod 3, with the second reinforcing rod 3 penetrating the first reinforcing rod 4. By providing a grid-like skeleton inside the EPS foam board body 1, the strength of the EPS foam board body 1 is greatly enhanced while still meeting its performance requirements. One end of the first reinforcing rod 4 on any one EPS foam board body 1 is threadedly connected to a first stud 5. The first stud 5 and the second stud 9 are respectively threadedly connected to the first reinforcing rod 4 on different EPS foam board bodies 1, facilitating assembly and disassembly. A limit block 7 is fixedly fitted onto the first stud 5. One end of the first reinforcing rod 4 on the other EPS foam board body 1 is threadedly fitted to a second stud 9. One end of the first stud 5 is fixed to a first connecting seat 6, which has a spline hole. One end of the second stud 9 is fixed to a second connecting seat 8, which has a sliding hole. The rotating shaft 2 is provided with a spline groove 11 that matches the spline hole. The rotating shaft 2 is slidably sleeved in the first connecting seat 6 through the spline hole and the spline groove 11. The rotating shaft 2 is located in the sliding hole of the second connecting seat 8. The second connecting seat 8 is equipped with a limiting component 10 for limiting the rotation of the rotating shaft 2. One end of the rotating shaft 2 is threaded with a nut 13, and the other end of the rotating shaft 2 is fixed with a stop. When the rotating shaft 2 is inserted into the spline hole on the first connecting seat 6 and the sliding hole on the second connecting seat 8, the spline groove 11 on the rotating shaft 2 mates with the spline hole, so that the rotating shaft 2 cannot be... The two EPS foam board bodies 1 can rotate within the first connecting seat 6 and within the second connecting seat 8, allowing them to rotate relative to each other. After rotating to the appropriate position, the rotating shaft 2 can be limited by the limiting component 10. Since the rotating shaft 2 cannot rotate within the first connecting seat 6, it also cannot rotate relative to the second connecting seat 8. Therefore, the two EPS foam board bodies 1 are stabilized in the rotated position and can rotate at the required angle. The overall structure is stable, and the two EPS foam board bodies 1 are easy to assemble and disassemble.

[0024] Referring to Figure 4, the limiting component 10 includes a positioning groove 12, a fixed base 14, a positioning insert 15, and a spring 17. The fixed base 14 is fixed on the second connecting base 8. The fixed base 14 is provided with a sliding groove, and the positioning insert 15 is slidably sleeved in the sliding groove. The spring 17 connects the sliding groove and the positioning insert 15. The rotating shaft 2 is provided with positioning grooves 12 arranged in a circular array. The positioning grooves 12 match the positioning insert 15. A sliding rod 16 is fixed on the positioning insert 15. The sliding rod 16 slides through the fixed base 14 and is fixed with a lever 18. When the positioning insert 15 is inserted into the positioning groove 12, the positioning insert 15 can be stably inserted into the positioning groove 12 under the action of the spring 17. In this way, the rotating shaft 2 cannot rotate relative to the second connecting base 8. When it is necessary to release, the lever 15 can be pulled by the lever 18 and the sliding rod 16 to pull the lever 15 out of the positioning groove 12. In this way, the two EPS foam board bodies 1 can rotate relative to each other again.

[0025] Working principle: During use, a grid-like skeleton is set inside the EPS foam board body 1, which greatly enhances the strength of the EPS foam board body 1 while meeting the performance requirements. The first stud 5 and the second stud 9 are respectively threaded to the first reinforcing rod 4 on different EPS foam board bodies 1, which facilitates disassembly and assembly. The rotating shaft 2 is inserted into the spline hole on the first connecting seat 6 and the sliding hole on the second connecting seat 8. The spline groove 11 on the rotating shaft 2 is connected with the spline hole, so the rotating shaft 2 cannot rotate in the first connecting seat 6 but can rotate in the second connecting seat 8. Thus, the two EPS foam board bodies 1 can rotate relative to each other. After rotating to the appropriate position, the rotating shaft 2 can be limited by the limiting component 10. Since the rotating shaft 2 cannot rotate in the first connecting seat 6, it cannot rotate relative to the second connecting seat 8. Therefore, the two EPS foam board bodies 1 are stabilized in the rotated position and can rotate at the required angle. The overall structure is stable, and the two EPS foam board bodies 1 are very easy to disassemble and assemble.

[0026] The operating principle of the limiting component 10 is as follows: the positioning insert 15 is inserted into the positioning groove 12. Under the action of the spring 17, the positioning insert 15 can be stably inserted into the positioning groove 12, so the rotating shaft 2 cannot rotate relative to the second connecting seat 8. When it is necessary to release, the lever 18 and the slide rod 16 can be used to pull the lever 15 to pull it out of the positioning groove 12, so that the two EPS foam board bodies 1 can rotate relative to each other again.

[0027] 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.
