Description

Technical Field

[0001] This utility model relates to the field of circular hole plastic sheet technology, specifically to a compression-resistant circular hole plastic sheet structure. Background Technology

[0002] Currently, the structural design of perforated plastic sheets often focuses more on meeting basic requirements such as water permeability, air permeability, or lightweighting, while the consideration of compression resistance is significantly insufficient.

[0003] Specifically, existing perforated plastic sheets typically use a single flat substrate with uniformly distributed circular through holes. The overall structural strength of the substrate mainly depends on its thickness and material hardness. When such plastic sheets are subjected to external pressure, especially under concentrated loads or uneven pressure, the substrate area around the circular holes is prone to deformation due to stress concentration. In severe cases, problems such as cracking and collapse may occur. Therefore, we need to propose a perforated plastic sheet structure that is resistant to compression. Utility Model Content

[0004] The purpose of this utility model is to provide a compression-resistant circular hole plastic plate structure. By setting a gradually decreasing circular hole with a diameter that gradually decreases from the center to the outside, a circular hole edge reinforcement structure, and staggered reinforcing ribs on the upper and lower parts of the substrate, the structure achieves the effects of optimizing the stress distribution, enhancing local strength, dispersing the compression load, and improving the overall compression resistance performance, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A compression-resistant perforated plastic plate structure includes: a substrate having a plurality of sets of perforated holes inside, wherein the plurality of sets of perforated holes are all arranged with a gradually decreasing diameter, the diameter of which gradually decreases from the center to the outside to form a gradient structure;

[0007] The edge reinforcement structures of the circular holes are respectively set at the top and bottom of the circular holes, and are integrally formed with the substrate.

[0008] Interlocking reinforcing ribs are integrally formed and installed on the top and bottom of the substrate.

[0009] Preferably, the edge reinforcement structure of the circular hole is configured as an annular flange, and the top of the annular flange is provided with an arc transition portion.

[0010] Preferably, the staggered reinforcing ribs include several sets of longitudinal ribs, and transverse short ribs are provided between adjacent sets of longitudinal ribs.

[0011] Preferably, a receiving cavity is reserved between two adjacent sets of longitudinal ribs and transverse short ribs, and the edge reinforcement structure of the circular hole and the circular hole are both located inside the receiving cavity.

[0012] Preferably, anti-slip textures are provided on the outer walls of several groups of longitudinal ribs and transverse short ribs.

[0013] Preferably, the Z-axis cross-sections of several groups of longitudinal ribs and transverse short ribs are all arranged in a trapezoidal shape.

[0014] Preferably, the substrate has a reinforcing frame on all four sides, and the outer wall of the reinforcing frame is provided with a wear-resistant coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model effectively optimizes the stress distribution of the substrate through a gradient structure design with gradually changing apertures. The apertures of several sets of circular holes gradually decrease from the center outwards, so that when the substrate is subjected to concentrated loads or uneven extrusion, the load can be gradually transferred along the gradient direction of the aperture change. This avoids the problem of stress concentration in a single area in the traditional uniform aperture design, significantly reduces the risk of deformation due to excessive local stress, and improves the overall extrusion resistance stability of the substrate. Secondly, the integral molding of the circular hole edge reinforcement structure with the substrate directly enhances the structural strength of this stress-sensitive area around the circular hole. This reinforcement structure can specifically resist the stress concentration at the edge of the circular hole, reducing the possibility of cracking or collapse around the circular hole under extrusion. At the same time, the integral molding process ensures the integrity and stability of the structure and will not create new weak points due to additional splicing parts.

[0017] 2. By using interlocking reinforcing ribs integrally formed at the top and bottom of the substrate, a comprehensive stress support system is constructed. The interlocking reinforcing ribs can quickly disperse local extrusion loads to the entire substrate, optimize the force transmission path, and enable the substrate to transmit force to a wider area through the reinforcing ribs when facing concentrated loads or uneven extrusion, further improving the overall deformation resistance and structural rigidity of the substrate.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] An anti-extrusion circular hole plastic sheet structure mainly includes: a base plate 1, circular holes 2, circular hole edge reinforcement structure 3, staggered reinforcing ribs 4, receiving cavity 7, and reinforcing frame 8. The base plate 1, as the basic load-bearing structure of the entire plastic sheet, is made of polypropylene material and integrally molded by injection molding. Polypropylene material has good plasticity, strength, and toughness. Several sets of circular holes 2 are opened inside the base plate 1. The sets of circular holes 2 are all set with gradually decreasing hole diameters, which gradually decrease from the center to the outside to form a gradient structure. By setting the gradient structure with gradually decreasing hole diameters, the load can be gradually transferred along the direction of hole diameter change, thereby optimizing the stress distribution of the sheet and avoiding stress concentration in a single area.

[0026] In practical applications, when the plastic sheet is subjected to a vertical compressive load, this gradient structure can gradually diffuse the load from the center of the circular hole 2 to the periphery, so that the entire substrate 1 can bear the pressure more evenly, reducing the risk of damage caused by excessive local stress, and effectively improving the stability and reliability of the plastic sheet under complex stress environments.

[0027] The circular hole edge reinforcement structure 3 is respectively disposed at the top and bottom of the circular hole 2, and is integrally formed with the substrate 1. The circular hole edge reinforcement structure 3 is specifically configured as an annular flange 5, and the top of the annular flange 5 is provided with a circular arc transition portion 6. By setting the annular flange 5 and the circular arc transition portion 6, the structural strength around the circular hole 2 is enhanced, thereby reducing stress concentration at the edge of the circular hole 2 and reducing the risk of breakage.

[0028] Interlaced reinforcing ribs 4 are integrally formed on the top and bottom of the substrate 1. The interlaced reinforcing ribs 4 include several sets of longitudinal ribs 401, and transverse short ribs 402 are provided between two adjacent sets of longitudinal ribs 401. By setting the interlaced reinforcing ribs 4 composed of longitudinal ribs 401 and transverse short ribs 402, an all-round force support system is constructed, which achieves the effect of quickly dispersing local loads to the entire substrate 1.

[0029] The edge reinforcement structure 3 of the circular hole is set as an annular flange 5, and the top of the annular flange 5 is provided with a rounded transition portion 6. When the plastic sheet is subjected to external pressure, the edge of the circular hole 2 is the part most prone to stress concentration. The annular flange 5 increases the thickness of the edge of the circular hole 2, improving its resistance to deformation; while the rounded transition portion 6 allows the stress to be transmitted more smoothly, avoiding the sharp concentration of stress at sharp corners, thereby effectively preventing the edge of the circular hole 2 from cracking due to excessive stress and extending the service life of the plastic sheet.

[0030] The staggered reinforcing ribs 4 include several sets of longitudinal ribs 401, with transverse short ribs 402 positioned between adjacent sets of longitudinal ribs 401. When a local area of ​​the plastic sheet is subjected to external force, the longitudinal ribs 401 and transverse short ribs 402 can cooperate to quickly transfer the load of that local area to the surrounding area, allowing the entire substrate 1 to share the pressure and preventing deformation or damage caused by excessive local stress. This comprehensive stress-bearing support system enables the plastic sheet to maintain good stability when subjected to loads of different directions and magnitudes.

[0031] A cavity 7 is reserved between two adjacent sets of longitudinal ribs 401 and transverse short ribs. The edge reinforcement structure 3 of the circular hole and the circular hole 2 are both located inside the cavity 7. By setting the cavity 7 and placing the relevant structure of the circular hole 2 inside it, the staggered reinforcing ribs 4 and the circular hole 2 structure cooperate with each other and do not interfere with each other, thus achieving the effect of ensuring that their respective functions are performed normally.

[0032] Several sets of longitudinal ribs 401 and transverse short ribs 402 are provided with anti-slip textures 10 on their outer walls. By providing anti-slip textures 10, the friction of the reinforcing rib surface is increased, achieving the effect of preventing slippage during handling or use. During use, when the plastic board is used as a work platform or comes into contact with other objects, the anti-slip textures 10 ensure that items placed on it will not easily slide, improving the safety and stability of use.

[0033] The Z-axis cross-sections of several sets of longitudinal ribs 401 and transverse short ribs 402 are all trapezoidal. By setting the reinforcing ribs with trapezoidal cross-sections, the contact area between the reinforcing ribs and the substrate is increased, thereby improving the load-bearing capacity of the reinforcing ribs and the stability of the connection with the substrate.

[0034] In use, the trapezoidal cross-section design allows the longitudinal ribs 401 and the transverse short ribs 402 to better transfer the force to the substrate 1 when subjected to vertical force, reducing stress concentration. At the same time, the larger contact area also enhances the connection strength between the staggered reinforcing ribs 4 and the substrate 1, making the two more firmly bonded and less prone to loosening or falling off, thereby improving the structural stability of the entire plastic sheet.

[0035] The substrate 1 has reinforcing frames 8 on all four sides, and a wear-resistant coating 9 is applied to the outer wall of the reinforcing frames 8. By using the reinforcing frames 8 and the wear-resistant coating 9, the structural strength and wear resistance of the substrate edges are enhanced, reducing damage to the edges from impacts and friction. In use, the reinforcing frames 8 protect the edges of the substrate 1, preventing deformation or breakage when subjected to external impacts; the wear-resistant coating 9 effectively resists friction and wear during daily use, extending the service life of the reinforcing frames 8. The combination of these two features makes the edges of the plastic sheet more robust and durable, adaptable to various complex usage environments.

[0036] Working Principle: When this compression-resistant circular hole plastic plate structure is subjected to external pressure, firstly, the gradually changing diameter circular holes 2 on the substrate 1 come into play. Their gradient structure allows the load to be gradually transferred along the direction of the hole diameter change, optimizing the stress distribution on the substrate 1 and avoiding stress concentration in a single area. Simultaneously, the annular flange 5 and the arc transition portion 6 at the edge of the circular hole 2 enhance the structural strength around the hole 2, reducing stress concentration at the edge of the hole 2 and lowering the risk of breakage. Next, the all-around load-bearing support system constructed by the longitudinal ribs 401 and the transverse short ribs 402 in the staggered reinforcing ribs 4 quickly disperses the local load to the entire substrate 1, enabling the substrate 1 to bear pressure evenly. The receiving cavity 7 provides deformation space for the circular holes 2 and their edge reinforcement structure, ensuring that the staggered reinforcing ribs 4 and the circular hole 2 structure do not interfere with each other and each functions normally. The anti-slip texture 10 on the outer wall of the longitudinal ribs 401 and the transverse short ribs 402 increases surface friction and prevents slippage during the stress process. The longitudinal ribs 401 and transverse short ribs 402 of the trapezoidal cross-section increase the contact area with the substrate 1, improving its load-bearing capacity and connection stability with the substrate 1. Finally, the reinforcing frame 8 and wear-resistant coating 9 on the four sides of the substrate 1 enhance the structural strength and wear resistance of the substrate 1 edges, reducing damage to the edges during collisions and friction. Through the synergistic effect of these structures, the plastic sheet can effectively resist extrusion and maintain good structural stability and performance.
