Description

Technical Field

[0001] This utility model relates to the field of PVC board technology, and specifically to a casual PVC board. Background Technology

[0002] PVC panels are high-molecular polymer sheets made primarily from polyvinyl chloride resin through processes such as extrusion and calendering. They are lightweight, moisture-proof, flame-retardant, corrosion-resistant, and easy to process. Furthermore, their surface can be coated and printed to create diverse decorative effects, making them widely used in interior decoration, especially for walls and ceilings. Installing PVC panels not only enhances the aesthetics of a space but also forms a protective layer on the underlying wall, extending its lifespan. They also provide auxiliary functions such as sound insulation and heat insulation.

[0003] Currently, PVC panels are mainly bonded directly to the wall substrate surface using adhesives (such as all-purpose adhesives and structural adhesives). While this method allows for rapid installation and ensures a smooth finish, it has significant drawbacks in practical applications: 1. Due to the high bonding strength of the adhesive layer after curing, disassembly during partial repairs, panel replacements, or spatial function adjustments can easily lead to interface delamination between the PVC panel and the adhesive layer, or between the adhesive layer and the wall substrate. This manifests as damage or breakage of the PVC panel, or the wall substrate being peeled off along with it, making it impossible to maintain the integrity of the panel and hindering its direct reuse. This not only increases maintenance costs but also results in significant material waste, contradicting the current green building principles of sustainable development and resource recycling. 2. Adhesives degrade after a certain period of use, causing the PVC panel to peel off at the connection point with the wall substrate, or even fall off, affecting normal use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable PVC board that can be installed without adhesives, using mechanical connections to extend its service life.

[0005] The objective of this utility model is achieved through the following solution:

[0006] A casual PVC board includes a board material. Connecting grooves are formed on both the upper and lower sides of the board material, with the groove openings facing outwards. A connecting female is provided within each connecting groove, and a connecting male is inserted into the connecting female. The connecting male has an installation hole. A clearance hole is formed directly opposite the connecting female and connecting male, and a through hole is formed on the board material opposite the clearance hole. The board material, connecting female, and connecting male are fixedly connected by bolts.

[0007] In this way, by creating connecting grooves on both the upper and lower ends of the board and using pluggable female and male connectors, along with bolts for secure fixing, modular, glue-free installation of PVC boards is achieved. This eliminates the need for traditional adhesive bonding. During installation, simply fix the male connectors of adjacent boards to the installation location (e.g., a wall) with expansion bolts, then connect the female connector to the board, and finally plug in the male and female connectors and tighten them with bolts. This prevents the male and female connectors from separating, improving reliability. For disassembly, simply remove the bolts to remove the board. The cooperation between the male and female connectors not only ensures precise alignment between boards but also creates multi-point mechanical fixation after bolt tightening, effectively preventing deformation or detachment of the boards due to stress concentration, significantly improving installation stability and reusability.

[0008] Preferably, the female connector includes a female plate and inner plates fixedly installed on both sides of the female plate, the inner plates being perpendicular to the female plate; the male connector includes a male plate and outer plates fixedly installed on both sides of the male plate, the outer plates being perpendicular to the male plate, and when the female connector and the male connector are inserted into each other, the outer plates are located outside the inner plates.

[0009] Preferably, the bottom of the connecting groove is provided with a socket, and the female plate of the connecting seat is provided with a protruding plug end that is engaged with the socket.

[0010] Preferably, the plate has a groove at the outer end opposite to the bolt, and the groove communicates with the through hole.

[0011] Preferably, both the female connector and the male connector are made of metal sheet.

[0012] In summary, this utility model has the advantages of requiring no adhesive, achieving installation through mechanical connection, and extending service life. Attached Figure Description

[0017] Figure 5 This is a schematic diagram showing the connection between the female connector and the male connector. Detailed Implementation

[0018] like Figure 1-5As shown, a casual PVC board includes a board 1. Connecting grooves 2 are provided on both the upper and lower sides of the board, with the groove openings facing outwards. A connecting female 3 is provided within each connecting groove, and a connecting male 4 is inserted into the connecting female 3. The connecting male 4 has mounting holes 5. A clearance hole 6 is provided directly opposite the connecting female 3 and the connecting male 4. A through hole 7 is provided directly opposite the clearance hole in the board. The board, the connecting female 3, and the connecting male 4 are fixedly connected by bolts 8.

[0019] In this way, by creating connecting grooves on both the upper and lower ends of the board and using pluggable female and male connectors, along with bolts for secure fixing, modular, glue-free installation of PVC boards is achieved. This eliminates the need for traditional adhesive bonding. During installation, simply fix the male connectors of adjacent boards to the installation location (e.g., a wall) with expansion bolts, then connect the female connector to the board, and finally plug in the male and female connectors and tighten them with bolts. This prevents the male and female connectors from separating, improving reliability. For disassembly, simply remove the bolts to remove the board. The cooperation between the male and female connectors not only ensures precise alignment between boards but also creates multi-point mechanical fixation after bolt tightening, effectively preventing deformation or detachment of the boards due to stress concentration, significantly improving installation stability and reusability.

[0020] In implementation: The female connector includes a female plate 9 and inner plates 10 fixedly installed on both sides of the female plate, the inner plates being perpendicular to the female plate; the male connector includes a male plate 11 and outer plates 12 fixedly installed on both sides of the male plate, the outer plates being perpendicular to the male plate. When the female connector and the male connector are inserted into each other, the outer plates are located outside the inner plates. Thus, the arrangement of the inner and outer plates forms a nested mechanical interlocking structure, reducing installation errors and improving the reliability of the connection.

[0021] In implementation: The bottom of the connecting groove is provided with a socket 13, and the female plate of the connecting female is provided with a protruding plug end 14 that engages with the socket. In this way, the socket at the bottom of the groove forms a plug-in positioning structure with the plug end of the connecting female, which pre-fixes the installation of the connecting female and reduces the installation difficulty.

[0022] Specifically, the plug and socket are interference-fitted to ensure reliable connection.

[0023] In practice: The plate has a groove 15 on the outer end opposite the bolt, and the groove is connected to the through hole.

[0024] In this way, the slot design allows space for the bolt end, preventing it from being located on the outer side of the sheet metal and ensuring the flatness of the outer side of the sheet metal. At the same time, the bolt can be easily removed through the gap between the slot and the end.

[0025] In practice: Both the female and male connectors are made of sheet metal. This metal material ensures a long service life and good locking effect. Alternatively, steel can be stamped, such as stainless steel, or other materials like iron sheets.

[0026] Specifically, the connecting groove, through hole, and socket are pre-machined on the sheet metal. Bolts are screwed in laterally to connect the male and female connectors to the sheet metal. In practice, the diameter of the through hole is slightly smaller than the bolt diameter for better bolt tightening.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
