Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC board technology, and specifically to a spliced PVC board. Background Technology
[0002] PVC panels are lightweight, corrosion-resistant, and easy-to-process building and decorative materials made primarily from polyvinyl chloride resin through extrusion, calendering, or coating processes. Due to manufacturing process and transportation cost limitations, PVC panels are typically produced in smaller sizes (e.g., 1-2 meters wide), while in practical applications (such as wall surfaces) large-area installation is required, necessitating splicing to achieve a cohesive look.
[0003] Currently, the direct adhesive bonding method is used when splicing PVC boards, which has the following problems: 1. The operation is cumbersome, requiring precise application and alignment of adhesive between adjacent PVC boards, and relying on the curing time of the adhesive, resulting in low efficiency; 2. The adhesive is easily affected by temperature, leading to delamination or false bonding; 3. It is difficult to disassemble after bonding, and replacement requires damaging the board, increasing costs. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a splicing PVC board that can be connected without adhesive, is stable and reliable, and is easy to use.
[0005] The objective of this utility model is achieved through the following solution:
[0006] A type of interlocking PVC panel includes at least two rectangular panels. Each panel has a mounting groove on both sides of its corner area. The mounting groove is a stepped groove, with the larger end on the outer side and the smaller end on the inner side. The mounting grooves of two adjacent panels face each other and are connected by a connecting block. The connecting block has end blocks at both ends that mate with the smaller ends of the mounting grooves. Intermediate blocks protrude from both sides of the connecting block and mate with the larger ends of the mounting grooves. Insert plates are fixedly installed on both sides of the intermediate blocks corresponding to the steps. The panels have slots for inserting the insert plates.
[0007] In this way, mounting grooves and slots are pre-cut on the panels. When connecting adjacent panels, the connecting block is aligned with the mounting groove and pushed laterally. This causes the insert plate to be inserted into the slot, while the end block enters the smaller end, and half of the middle block enters the larger end. The other panel is then moved closer, so that the insert plate on the other side of the connecting block is inserted into the slot of the other panel, while the end block on the other side enters the smaller end, and the other half of the middle block enters the larger end, until the sides of the two panels are flush, completing the splicing of the two panels. The stepped groove facilitates the mating connection between the insert plate and the slot. Splicing of two panels can be achieved without adhesive.
[0008] Preferably, the end of the insert plate is a pointed tip.
[0009] Preferably, the connecting block has a through hole corresponding to the plate, a pin is slidably fitted inside the through hole, and the end of the pin is fixed with a spike for inserting into the plate.
[0010] Preferably, the spike is conical.
[0011] Preferably, a groove is provided on the outside of the perforation, and the groove communicates with the perforation.
[0012] This invention has the advantages of achieving connection without adhesive, being stable and reliable, and being easy to use. Attached Figure Description

[0016] Figure 4 This is a schematic diagram of the disassembled structure of the connector. Detailed Implementation
[0017] like Figure 1-4 As shown, a splicing PVC board includes at least two boards 1, each board being rectangular. Each board has a mounting groove 2 on both sides of its corner area. The mounting groove is a stepped groove, with the larger end 3 on the outer side and the smaller end 4 on the inner side. The mounting grooves of two adjacent boards are aligned and connected by a connecting block 5. The connecting block has end blocks 6 at both ends that mate with the smaller ends of the mounting grooves. The connecting block has protruding middle blocks 7 on both sides that mate with the larger ends of the mounting grooves. Insert plates 8 are fixedly installed on both sides of the middle blocks corresponding to the steps. The boards have slots 9 for inserting the insert plates.
[0018] In this way, mounting grooves and slots are pre-cut on the panels. When connecting adjacent panels, the connecting block is aligned with the mounting groove and pushed laterally. This causes the insert plate to be inserted into the slot, while the end block enters the smaller end, and half of the middle block enters the larger end. The other panel is then moved closer, so that the insert plate on the other side of the connecting block is inserted into the slot of the other panel, while the end block on the other side enters the smaller end, and the other half of the middle block enters the larger end, until the sides of the two panels are flush, completing the splicing of the two panels. The stepped groove facilitates the mating connection between the insert plate and the slot. Splicing of two panels can be achieved without adhesive.
[0019] Of course, in actual implementation, the sheet material can be square. The connecting block and the stepped groove are interference-fitted, and the insert plate and the slot are interference-fitted to improve reliability.
[0020] In practice, the end of the insert plate is a pointed tip 10. This reduces the resistance when the insert plate is inserted into the slot.
[0021] In implementation, the connecting block has a through hole 11 corresponding to the plate, and a pin 12 is slidably fitted inside the through hole. The end of the pin is fixed with a spike 13 for inserting into the plate. After the pin passes through the connecting block, it is embedded into the plate through the spike, forming an additional locking perpendicular to the insertion direction of the plate, preventing the connecting block from detaching from the plate and improving the reliability of the splicing.
[0022] In practice, the spikes are conical in shape to facilitate insertion into the plate.
[0023] In practice, a slot 14 is provided on the outer side of the perforation, and the slot communicates with the perforation. The size of the slot is larger than the diameter of the pin, making it easy to remove the pin through the slot.
[0024] 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.
