Technical Field
[0001] This utility model belongs to the field of PVC roll technology, specifically relating to a detachable modular anti-slip PVC roll. Background Technology
[0002] PVC rolls are plastic materials made from polyvinyl chloride (PVC) resin as the main raw material, produced through processes such as calendering (e.g., PVC floor rolls) and extrusion (e.g., waterproof rolls). They are widely used in construction, decoration, and industrial fields.
[0003] Currently, in order to ensure the stability of the rolled material after it is laid and to avoid misalignment between two adjacent rolled materials, splicing structures are usually set on the rolled material.
[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN213805906U discloses "a textured PVC anti-slip roll material", which includes a roll material body, an auxiliary roll material body that is interference-connected to one end of the roll material body, a screw hole that is the same size as a threaded screw on one side of the auxiliary roll material body, a textured surface that is inlaid and connected to the top of the roll material body, and a slot that is inlaid and connected to the side of the roll material body away from the auxiliary roll material body, with rubber air cushions inlaid and connected to both sides inside the slot.
[0005] While existing PVC anti-slip rolls, including those mentioned above, can ensure the stability of splicing two adjacent roll bodies, they can only stably splice multiple roll bodies along the length direction, but lack the necessary splicing structure along the width direction, which makes it easy for misalignment to occur between adjacent sets of roll bodies.
[0006] To address the aforementioned problems, this utility model proposes a detachable modular anti-slip PVC roll material. Utility Model Content

[0032] 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.
[0033] Please see Figures 1-5 The present invention provides the following technical solution: a detachable modular anti-slip PVC roll, including a roll body 1, the roll body 1 having a rectangular structure, and further including: multiple connecting protrusions 11, multiple anti-slip rubber strips 2 and a PVC top sheet 3.
[0034] Furthermore, by Figures 1-3As shown in this embodiment, multiple equally spaced connecting protrusions 11 are fixed on two adjacent sides of the roll body 1, and connecting grooves 12 for the connecting protrusions 11 to be inserted are provided on the other two adjacent sides. Multiple anti-slip rubber strips 2 are installed at equal intervals along the horizontal direction on the bottom surface of the roll body 1. The PVC top sheet 3 is detachably installed on the top surface of the roll body 1, and anti-slip protrusions 31 are evenly distributed on the top surface of the PVC top sheet 3. With the above solution, when in use, the adjacent sides of the roll body 1 are respectively provided with connecting protrusions 11 and connecting grooves 12, and the mechanical interlocking principle of the convex and concave structure is used to achieve rapid splicing.
[0035] During installation, align the connecting protrusion 11 of one roll body 1 with the connecting groove 12 of the adjacent roll body 1, and press to make the connecting protrusion 11 embed into the connecting groove 12 to form a tight snap connection. This design allows multiple roll bodies 1 to be combined arbitrarily in the horizontal direction to quickly form an anti-slip paving surface of any area, which is suitable for anti-slip needs of different scenarios.
[0036] During disassembly, simply pry the connection point between the connecting protrusion 11 and the connecting groove 12 from the edge to remove a single piece of the roll body 1 for replacement or maintenance, significantly reducing subsequent maintenance costs.
[0037] The anti-slip rubber strips 2, which are installed at equal intervals on the bottom surface of the roll body 1, are made of rubber material with a high coefficient of friction. When in contact with the ground, they generate strong static friction. When the roll body 1 is subjected to horizontal thrust, the anti-slip rubber strips 2 deform and conform to the fine uneven structure of the ground, preventing the roll body 1 from sliding as a whole. Especially on smooth tile, marble or cement floors, the elastic deformation of the anti-slip rubber strips 2 can fill the gaps in the ground, maximizing the contact area between the roll body and the ground, and significantly improving the overall anti-slip performance.
[0038] The anti-slip protrusions 31 on the top surface of the PVC top sheet 3 are distributed in a regular array. By increasing the roughness of the contact surface, the friction coefficient between the person or object and the surface of the roll body 1 is increased. When the person or object comes into contact with the top surface, the anti-slip protrusions 31 are embedded in the shoe sole pattern or the bottom surface of the object, effectively dispersing the shear force generated during walking or carrying.
[0039] Because the PVC top sheet 3 is detachable, when the surface of the PVC top sheet 3 is worn due to long-term use, it is not necessary to remove the entire roll material. Only the PVC top sheet 3 needs to be replaced, which greatly reduces maintenance costs and time. At the same time, the detachable design facilitates regular deep cleaning, preventing dirt from accumulating between the PVC top sheet 3 and the roll material body 1, thus extending the overall service life.
[0040] Preferably, by Figures 1-3As shown in this embodiment, the connecting protrusion 11 is a trapezoidal block and the connecting groove 12 is a trapezoidal slot. With the above solution, when in use, the connecting protrusion 11 and the connecting groove 12 adopt a trapezoidal structure and form a "self-locking" connection by utilizing the wedge principle of the trapezoidal inclined side. When the trapezoidal block is embedded in the trapezoidal slot, the inclined surface contact generates a positive pressure perpendicular to the contact surface. This pressure increases with the increase of lateral load, forming a wedge-shaped tenon and mortise-and-tenon anti-loosening effect. Compared with the rectangular protrusion and concave structure, when the trapezoidal connection is subjected to horizontal thrust, the inclined surface component will further tighten the adjacent roll body 1, effectively resisting the loosening of the connection caused by vibration and impact. It is especially suitable for scenarios with high-frequency stepping or frequent equipment movement, so that the overall paving surface maintains a long-term stable splicing state.
[0041] Preferably, by Figures 1-3 As shown, in this embodiment, the outer wall of the connecting protrusion 11 fits against the inner wall of the connecting groove 12. With the above solution, during use, the high-precision fit between the outer wall of the connecting protrusion 11 and the inner wall of the connecting groove 12 forms a physical sealing barrier, effectively preventing dust and other impurities from entering the splicing gap.
[0042] The bonding design maximizes the contact area of the connection interface. The load is transferred through complete surface contact rather than point or line contact, avoiding bulge breakage or groove wear caused by local stress concentration. When the roll body 1 is subjected to dynamic load, the bonding convex and concave structure can evenly distribute the shear force to the entire contact surface.
[0043] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further includes: a first magnetic absorbing piece 4 and a second magnetic absorbing piece 5. A first mounting groove 13 is opened on the top surface of the roll body 1, and the first magnetic absorbing piece 4 is bonded and fixed in the first mounting groove 13. A second mounting groove 32 is opened on the bottom surface of the PVC top sheet 3, and the second magnetic absorbing piece 5 is bonded and fixed in the second mounting groove 32 and attracts the first magnetic absorbing piece 4. With the above scheme, when in use, the first magnetic absorbing piece 4 and the second magnetic absorbing piece 5 adopt a permanent magnet design with opposite poles, and use the magnetic attraction force to realize the automatic alignment and connection between the PVC top sheet 3 and the roll body 1.
[0044] During installation, simply align the PVC top sheet 3 with the roll body 1, and the magnetic force of the magnetic plate will automatically guide the second installation slot 32 to precisely align with the first installation slot 13. No manual calibration is required, enabling quick installation of the PVC top sheet 3. It also facilitates the disassembly, repair, or replacement of the PVC top sheet 3.
[0045] It should be noted that the thickness of magnetic piece 4 and magnetic piece 5 is the same, but the depth of mounting groove 13 and mounting groove 32 is different. Specifically, the depth of mounting groove 13 is greater than the thickness of magnetic piece 4, while the depth of mounting groove 32 is less than the thickness of magnetic piece 5. When magnetic piece 4 and magnetic piece 5 are attracted together, magnetic piece 5 will be embedded in mounting groove 13, forming a stable mechanical blocking effect, which can effectively prevent the PVC top sheet 3 from sliding horizontally.
[0046] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, four No. 1 mounting slots 13 are opened at the four corners of the top surface of the roll body 1, and four No. 2 mounting slots 32 are opened at the four corners of the bottom surface of the PVC top sheet 3. There are four No. 1 magnetic suction pieces 4 and four No. 2 magnetic suction pieces 5 diagonally distributed. After adopting the above scheme, when in use, the diagonally distributed No. 1 magnetic suction pieces 4 and No. 2 magnetic suction pieces 5 form a stable rectangular force matrix, so that the connection interface between the PVC top sheet 3 and the roll body 1 generates a uniform normal attraction force, which further improves the stability of the installation of the PVC top sheet 3.
[0047] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, it further includes: a fixing strip 21, which is integrally formed on the top surface of the anti-slip rubber strip 2. A fixing groove 14 for the fixing strip 21 to be embedded is provided on the bottom surface of the roll body 1. With the above solution, during use and installation, the fixing strip 21 of the anti-slip rubber strip 2 is aligned with the fixing groove 14. By pressing, the elastic rubber is slightly deformed. After the fixing strip 21 is fully embedded in the fixing groove 14, it returns to its original shape. The elastic force of the material forms a mechanical engagement with the inner wall of the fixing groove 14, thus completing the installation of the anti-slip rubber strip 2. The installation is convenient, and it is also convenient to disassemble and replace the damaged anti-slip rubber strip 2.
[0048] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown in this embodiment, both the fixing strip 21 and the fixing groove 14 are trapezoidal structures. With the above solution, when in use, the fixing strip 21 and the fixing groove 14 adopt a trapezoidal structure and form a "self-locking" connection by utilizing the wedge principle of the trapezoidal hypotenuse. When the fixing strip 21 is embedded in the fixing groove 14, the inclined surface contact generates a positive pressure perpendicular to the contact surface. This pressure increases with the increase of the lateral load, forming a wedge-shaped tenon and mortise-and-tenon anti-loosening effect. Compared with the rectangular convex and concave structure, the trapezoidal connection can effectively prevent the anti-slip rubber strip 2 from sliding horizontally or accidentally detaching from the roll body 1.
[0049] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the outer wall of the fixing strip 21 is attached to the inner wall of the fixing groove 14. After adopting the above solution, when in use, the high-precision attachment between the outer wall of the fixing strip 21 and the inner wall of the fixing groove 14 forms a physical sealing barrier, effectively preventing dust and other impurities from entering the splicing gap.
[0050] The fit design maximizes the contact area of the connection interface, and the load is transferred through complete surface contact rather than point or line contact, further improving the stability of the anti-slip rubber strip 2 installation.
[0051] Components not described in detail in this article are existing technologies.
[0052] The working principle and usage process of this utility model: When in use, the adjacent sides of the roll body 1 of this utility model are respectively provided with connecting protrusions 11 and connecting grooves 12, and the mechanical interlocking principle of the convex and concave structure is used to achieve rapid splicing.
[0053] During installation, align the connecting protrusion 11 of one roll body 1 with the connecting groove 12 of the adjacent roll body 1, and press to make the connecting protrusion 11 embed into the connecting groove 12 to form a tight snap connection. This design allows multiple roll bodies 1 to be combined arbitrarily in the horizontal direction to quickly form an anti-slip paving surface of any area, which is suitable for the anti-slip needs of different scenarios.
[0054] During disassembly, simply pry the connection point between the connecting protrusion 11 and the connecting groove 12 from the edge to remove a single piece of the roll body 1 for replacement or maintenance, which greatly reduces the later maintenance cost.
[0055] The anti-slip rubber strips 2, which are installed at equal intervals on the bottom surface of the roll body 1, are made of rubber material with a high coefficient of friction. When they come into contact with the ground, they generate strong static friction. When the roll body 1 is subjected to horizontal thrust, the anti-slip rubber strips 2 deform and conform to the fine uneven structure of the ground, preventing the roll body 1 from sliding as a whole. Especially on smooth tile, marble or cement floors, the elastic deformation of the anti-slip rubber strips 2 can fill the gaps in the ground, maximize the contact area between the roll and the ground, and significantly improve the overall anti-slip performance.
[0056] The anti-slip protrusions 31 on the top surface of the PVC top sheet 3 are distributed in a regular array. By increasing the roughness of the contact surface, the friction coefficient between the person or object and the surface of the roll body 1 is increased. When the person or object comes into contact with the top surface, the anti-slip protrusions 31 are embedded in the shoe sole pattern or the bottom surface of the object, effectively dispersing the shear force generated during walking or carrying.
[0057] Because the PVC top sheet 3 is detachable, when the surface of the PVC top sheet 3 is worn due to long-term use, it is not necessary to remove the entire roll material. Only the PVC top sheet 3 needs to be replaced, which greatly reduces maintenance costs and time. At the same time, the detachable design facilitates regular deep cleaning, preventing dirt from accumulating between the PVC top sheet 3 and the roll material body 1, thus extending the overall service life.
[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
