Description

Technical Field

[0001] This utility model relates to the field of plastic hollow board technology, specifically a modular plastic hollow board that is easy to assemble. Background Technology

[0002] Hollow plastic sheets (also known as hollow partition boards or corrugated sheets) are a type of high-performance engineering plastic sheet. Due to their advantages such as light weight, impact resistance, moisture and corrosion resistance, and recyclability, they are widely used in logistics packaging (such as turnover boxes and partitions), display and exhibition (such as shelves and display stands), and building protection (such as temporary fencing), occupying an important position in modern industrial and civil fields. Their unique honeycomb hollow structure endows the products with excellent mechanical properties.

[0003] Chinese Patent Publication No. CN202248643U discloses a hollow plastic board comprising a front panel and a back panel, wherein multiple reinforcing ribs are spaced apart between the front and back panels, and bamboo charcoal particles are filled in the gaps. The front panel has multiple small pores. This invention can be used as a ceiling decoration and has an air-purifying function.

[0004] In existing technologies, the use of a type of hollow plastic board only mentions that the product consists of a panel, a base plate, and reinforcing ribs, filled with bamboo charcoal particles, and the panel has small pores. When multiple pieces are spliced ​​together as ceiling decoration, on the one hand, due to the lack of a dedicated quick assembly structure, the installation process requires additional accessories such as screws and clips, as well as external tools such as screwdrivers and wrenches. Moreover, it is difficult for a single person to complete the positioning and fixing operation independently, and multiple people must cooperate, which undoubtedly significantly increases the manpower input and time cost of the installation process. On the other hand, because the product is not designed with a convenient disassembly structure, if it is necessary to inspect the ceiling, replace some hollow boards, or adjust the spatial layout, the disassembly process may damage the product itself or the surrounding installation structure. This not only makes the product difficult to reuse, but also fails to meet the needs of scenarios such as offices and showrooms that require frequent adjustments to the spatial layout. Therefore, we have made improvements to this issue and proposed a modular hollow plastic board that is easy to assemble. Utility Model Content

Both ends of the plurality of second reinforcing ribs are fixedly connected to the plastic hollow board body. V-shaped reinforcing ribs are fixedly installed on the outer side of the plurality of second reinforcing ribs and on the corresponding sides of the first reinforcing ribs. The V-shaped reinforcing ribs are inserted into the interior of the plastic hollow board body and fixedly connected to it. As a preferred technical solution of this application, U-shaped reinforcing ribs are provided on both sides of the interior of the hollow cavity, and both U-shaped reinforcing ribs are fixedly connected to the plastic hollow plate body.

[0018] Example 1: Please refer to the appendix of the instruction manual. Figure 1-4 A modular plastic hollow board for easy assembly includes a plastic hollow board body 1, with a hollow cavity 2 inside the plastic hollow board body 1. Two trapezoidal blocks 3 are fixedly installed on the top of the plastic hollow board body 1, and a sliding groove 4 is opened at the bottom of the plastic hollow board body 1 to cooperate with the two trapezoidal blocks 3. An I-shaped sliding plate 7 is slidably connected inside the plastic hollow board body 1. Multiple return springs 8 are provided on the side of the I-shaped sliding plate 7 away from the sliding groove 4. The two ends of the multiple return springs 8 are respectively fixedly connected to the plastic hollow board body 1 and the I-shaped sliding plate 7. Two first inserts 5 and two second inserts 6 are provided inside the two sliding grooves 4, and the two first inserts 5 and second inserts 6 are respectively provided inside the two sliding grooves 4. Each insertion rod 5 is fixedly connected to the plastic hollow board body 1, and multiple second insertion rods 6 are fixedly connected to the I-shaped sliding plate 7. The multiple second insertion rods 6 are slidably connected to the plastic hollow board body 1 and the slide groove 4. A side plate 9 is fixedly installed on one side of the I-shaped sliding plate 7, and the side plate 9 passes through one side of the plastic hollow board body 1 and is slidably connected to it. On the plastic hollow board body 1, on the corresponding sides of the hollow cavity 2, an outer layer, a middle layer and an inner layer are respectively provided from the outside to the inside. The outer layer is an impact-resistant and wear-resistant layer, the middle layer is a buffer reinforcement layer, and the inner layer is a support and connection layer. Limiting structures are provided inside the plastic hollow board body 1 on the corresponding sides of the side plate 9.

[0019] In this embodiment of the utility model, when it is necessary to assemble two hollow boards, the trapezoidal block 3 of the upper hollow board is aligned with the slide groove 4 of the lower hollow board and inserted along the slide groove 4. If adjustment or unlocking is required during insertion, the side plate 9 is pushed, which causes the I-shaped sliding plate 7 to compress the return spring 8. The I-shaped sliding plate 7 simultaneously drives the second insertion rod 6 to slide along the body, causing the second insertion rod 6 to be misaligned with the first insertion rod 5, thus releasing the restriction on the trapezoidal block 3 and facilitating the smooth insertion of the trapezoidal block 3. After insertion, the side plate 9 is released, the return spring 8 rebounds and pushes the I-shaped sliding plate 7 to return to its original position, and the second insertion rod 6 moves with the I-shaped sliding plate 7, intersecting with the first insertion rod 5 to firmly clamp the trapezoidal block 3 in the slide groove 4, completing the assembly. At the same time, the limiting structures on both sides of the side plate 9 are activated to fix the position of the side plate 9 and prevent accidental contact that could cause the assembly to loosen. The outer layer (impact-resistant and wear-resistant layer) directly contacts the external environment to resist collisions and friction; the middle layer (buffering and reinforcing layer) absorbs external impact forces and reduces vibration transmission; the inner layer (support and connection layer) provides a fixed foundation for the internal reinforcing structure (such as reinforcing ribs) and enhances the connection stability between the body and each component.

[0020] In this embodiment of the utility model, the "trapezoidal block 3 - sliding groove 4" positioning + "insertion rod - return spring 8" locking means that no external tools such as bolts and rivets are required, and a single person can complete the assembly / disassembly, improving the assembly efficiency by more than 60%. Meanwhile, the first insertion rod 5 and the second insertion rod 6 cross and limit each other, and together with the fitting design of the trapezoidal block 3 and the slide groove 4, they prevent the upper and lower plates from sliding relative to each other after assembly, thus improving the connection strength; the reset spring 8 automatically rebounds, eliminating the need for manual locking and simplifying the operation process. The outer layer is impact-resistant and wear-resistant, extending the service life of the main body; the middle layer provides cushioning and protects the internal load-bearing components (such as electronic components and precision parts); the inner layer provides support and a foundation for subsequent reinforcement structures, achieving a three-in-one basic performance of "protection-cushioning-support".

[0021] Example 2: Please refer to the appendix of the instruction manual. Figure 1-6 In a preferred embodiment of this utility model, the limiting structure includes a T-shaped limiting block 10, which is slidably connected to the side plate 9. The T-shaped limiting block 10 is inserted into the interior of the plastic hollow board body 1 and slidably connected thereto. A T-shaped limiting rod 11 is provided on one side of the T-shaped limiting block 10, and the T-shaped limiting rod 11 is fixedly connected to the plastic hollow board body 1. The T-shaped limiting rod 11 passes through one side of the T-shaped limiting block 10 and is slidably connected thereto. A compression spring 12 is provided on the outer side of the T-shaped limiting rod 11. The two ends of the compression spring 12 are fixedly connected to the plastic hollow board body 1 and the T-shaped limiting block 10, respectively. The side of the T-shaped limiting block 10 away from the T-shaped limiting rod 11 is inclined, and the lowest end of the inclined surface faces the side plate 9.

[0022] Multiple corrugated plates 17 and an antistatic coating are respectively provided on both sides of the plastic hollow board body 1 and on the side of the two outer layers that are far apart from each other. The multiple corrugated plates 17 are fixedly connected to the plastic hollow board body 1.

[0023] Rubber pads 18 are inlaid on the side of multiple corrugated plates 17 away from the plastic hollow plate body 1, and through grooves that cooperate with the side plates 9 are opened on the multiple corrugated plates 17.

[0024] The hollow cavity 2 is provided with a plurality of first reinforcing ribs 13. Both ends of the plurality of first reinforcing ribs 13 are fixedly connected to the plastic hollow board body 1. Both ends of the plurality of first reinforcing ribs 13 are fixedly connected to the plastic hollow board body 1 through the inner layer grooves, and are staggered from the closed-cell bubble area of ​​the middle layer.

[0025] Inside the hollow cavity 2, and between two adjacent first reinforcing ribs 13, there are second reinforcing ribs 14. Both ends of the multiple second reinforcing ribs 14 are fixedly connected to the plastic hollow plate body 1. On the outer side of the multiple second reinforcing ribs 14, and on the corresponding sides of the first reinforcing ribs 13, V-shaped reinforcing ribs 15 are fixedly installed. The V-shaped reinforcing ribs 15 are inserted into the interior of the plastic hollow plate body 1 and fixedly connected to it. The V-shaped openings of the multiple V-shaped reinforcing ribs 15 near the corrugated plate 17 correspond to the rubber pads 18 embedded on the two adjacent corrugated plates 17.

[0026] U-shaped reinforcing ribs 16 are provided on both sides of the interior of the hollow cavity 2. Both U-shaped reinforcing ribs 16 are fixedly connected to the plastic hollow board body 1. The open ends of the two U-shaped reinforcing ribs 16 are embedded in the slots of the inner layer and fixedly connected to the plastic hollow board body 1. Their arc-shaped sections are in contact with the foaming structure of the middle layer.

[0027] Positioning holes 19 are provided on one side of the plastic hollow board body 1 and at each of the four corners of one of the outer layers.

[0028] In this embodiment of the present invention, when the side plate 9 is released, the return spring 8 pushes the I-shaped sliding plate 7 to reset the side plate 9. The side of the side plate 9 presses against the inclined surface of the T-shaped limiting block 10, forcing the T-shaped limiting block 10 to slide away from the side plate 9 along the T-shaped limiting rod 11 and compressing the compression spring 12. When the side plate 9 is fully reset (the second insert 6 and the first insert 5 are in place), the groove on the side of the side plate 9 is aligned with the T-shaped limiting block 10. The compression spring 12 rebounds and pushes the T-shaped limiting block 10 into the groove of the side plate 9, thereby limiting the side plate 9 and preventing the side plate 9 from being accidentally pushed. When disassembly is required, the T-shaped limiting block 10 is pulled outward, the compression spring 12 is compressed again, and the T-shaped limiting block 10 is disengaged from the groove of the side plate 9. At this time, the side plate 9 can be pushed to unlock.

[0029] The corrugated plate 17 has a wave-shaped structure. When the side of the body is impacted, the corrugated structure absorbs the impact force through deformation, dispersing the concentrated impact force into dispersed stress, reducing direct damage to the outer layer of the body. At the same time, the corrugated plate 17 increases the contact area on the side of the body, improving the stability during stacking. Antistatic coatings (such as conductive polymer coatings) reduce surface resistance and quickly conduct away the static charge accumulated on the surface of the substrate, preventing electrostatic breakdown of internal electronic components or dust accumulation due to static electricity, which can affect the use of the substrate.

[0030] When multiple hollow boards are spliced ​​or stacked side by side, the rubber pad 18 directly contacts the adjacent boards, further absorbing the impact force through its own elasticity, while increasing the friction of the contact surface to prevent the boards from sliding during stacking; in addition, the rubber pad 18 can reduce collision noise during handling. When the side plate 9 is pushed or reset, it needs to pass through the side of the body. The through groove provides space for the side plate 9 to move, so as to avoid the corrugated plate 17 from obstructing the sliding of the side plate 9 and ensure smooth assembly / disassembly operations.

[0031] In this embodiment of the invention, the first reinforcing rib 13 is distributed along the length of the hollow cavity 2, dividing the hollow cavity 2 into multiple independent small cavities, reducing the deformation of the body under stress; it is fixed by the inner layer slot, and the connection strength is higher than that of direct bonding, preventing the reinforcing rib from falling off. The closed-cell bubble area of ​​the middle layer is the core of the buffering performance. The first reinforcing rib 13 is staggered with this area, which can prevent the reinforcing rib from squeezing the closed-cell bubble and causing a decrease in buffering performance; at the same time, the staggered design ensures that the supporting force of the first reinforcing rib 13 and the buffering force of the middle layer do not interfere with each other, and respectively play the roles of "supporting against deformation" and "buffering and absorbing energy".

[0032] The second reinforcing rib 14 further refines the support zones of the hollow cavity 2 based on the first reinforcing rib 13, improving the local resistance to deformation; the V-shaped reinforcing rib 15 has a "V" shaped structure, which transfers the force of the second reinforcing rib 14 to both sides of the body. At the same time, the V-shaped structure itself has high shear strength and can resist lateral impact.

[0033] When the side of the body is impacted, the impact force is transmitted to the rubber pad 18 through the corrugated plate 17. After the rubber pad 18 buffers the impact, the remaining stress is introduced into the interior of the V-shaped structure through the open end of the V-shaped reinforcing rib 15, and then dispersed to the whole body by the V-shaped reinforcing rib 15, so as to avoid local stress concentration that could lead to damage to the body.

[0034] U-shaped reinforcing ribs 16 are located on both sides of the hollow cavity 2, corresponding to the side areas of the main body. The high bending resistance of the "U" shape enhances the rigidity of the main body's sides, preventing side deformation during assembly or handling. The open end is embedded in the inner layer groove for a more secure fixation, and the curved section fits the middle layer foam structure, allowing for slight adjustments with the cushioning deformation of the middle layer without affecting its cushioning function. The U-shaped reinforcing ribs 16 connect the upper and lower inner walls of the main body, forming a "side frame" that transfers the force from the sides to the entire main body, preventing damage caused by isolated side stress.

[0035] When multiple hollow boards need to be spliced ​​together (such as to form the panels of display racks or warehouse shelves), positioning pins or bolts are inserted through positioning holes 19 to ensure that the four corners of adjacent hollow boards are precisely aligned, avoiding misalignment during splicing; at the same time, positioning holes 19 can be used with external frames (such as metal brackets) to achieve quick fixation of hollow boards to frames.

[0036] Example 3: Please refer to the appendix of the instruction manual. Figure 5 and Figure 7 In a preferred embodiment of the present invention, the hollow cavity 2 is movably connected to multiple flexible tubes, and both ends of the multiple flexible tubes penetrate the plastic hollow plate body 1 and are fixedly connected to it. Sealing rings are fixedly installed on the corresponding sides of the multiple flexible tubes, and anti-slip sleeves are embedded on both sides of the inner wall of the multiple flexible tubes.

[0037] In this embodiment of the invention, the flexible hose can be used to run electrical wires (such as lighting circuits for display racks) and transport fluids (such as cooling water pipes for small equipment), achieving an integrated design of "structural plate + functional pipeline"; the sealing ring prevents fluid leakage (such as when transporting liquids) or dust from entering the hose (such as when running electrical wires); the anti-slip sleeve increases the friction between the inner wall of the hose and the pipeline, preventing the pipeline from sliding inside the hose and causing positional displacement. The flexible hose is movably connected to the hollow cavity 2, and the position of the hose can be adjusted according to actual needs to adapt to different pipeline layouts.

[0038] In this embodiment of the utility model, there is no need to open additional pipeline holes. The pipeline can be laid directly through flexible hoses, which simplifies the installation process and avoids damaging the structural strength of the main body by opening holes. The design of sealing ring + anti-slip sleeve ensures that the pipeline is stable and sealed during use, which is suitable for scenarios that require pipeline integration (such as intelligent warehouse racks and display boards with lighting).

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
