Description

Technical Field

[0001] This utility model relates to the technical field of plastic-plastic board, and in particular to an impact-resistant plastic-plastic board. Background Technology

[0002] Wood-plastic composite (WPC) boards are a type of green and environmentally friendly material primarily made from wood (wood cellulose, bamboo cellulose, etc.) as the base material, mixed with thermoplastic polymers (PE, HDPE, PP plastics, etc.) and processing aids. The mixture is then extruded using mold equipment under heat. It combines the properties and characteristics of both wood and plastic, has a wood-like appearance, and features fire resistance, water resistance, corrosion resistance, moisture resistance, high strength, and energy saving. However, most existing WPC boards are integrally molded with internal cavities. This structure makes them prone to cracking in the cavities when subjected to significant external impacts, thus affecting the performance of the WPC board.

[0003] Chinese Patent Publication No. CN221143352U, published on November 24, 2010, discloses a plastic-plastic board profile, comprising: a plastic-plastic board body with multiple cavities inside; and a heat insulation mechanism disposed within the cavities to improve the thermal insulation performance of the plastic-plastic board body. A drawback of this invention is that the impact resistance of the cavities in the plastic-plastic board is relatively weak. Utility Model Content

[0004] The present invention aims to overcome the weakness of the existing one-piece molded plastic board in terms of impact resistance in the cavity, and provides an impact-resistant plastic board by installing a buffer plate on a split plastic board to improve its impact resistance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An impact-resistant plastic board includes a base, a top cover, fastening components, and a buffer plate. The base has several buffer grooves. The top cover is connected to the base. Fastening components are installed at both ends of the buffer grooves. The top cover is connected to the base through the fastening components. The buffer plate is placed in the buffer grooves. The lower end of the buffer plate is connected to the base, and the upper end of the buffer plate is connected to the top cover.

[0007] The plastic wood board is divided into a base and a top cover. The base and the top cover are processed separately, which can also improve the processing efficiency. Buffer grooves are provided on the base. The buffer grooves can reduce the weight. The top cover is installed above the base. The connection between the top cover and the base is achieved by fastening components installed in the buffer grooves to connect the top cover and the base together. Separating the processing of the base and the top cover allows a buffer plate to be installed in the buffer of the base. One end of the buffer plate is connected to the base, and the other end is connected to the top cover. The top cover above the buffer groove is supported by the buffer plate, thereby improving the impact resistance of the top cover. The split plastic wood board is convenient for installing a buffer device, achieving the purpose of improving the impact resistance by installing a buffer plate on the split plastic wood board.

[0008] Preferably, a plurality of buffer plates are evenly distributed in the buffer grooves. The cross-sectional shape of the buffer plate is in the shape of a "Ji" character. One end of the buffer plate with an opening contacts the bottom surface of the top cover, and the other end of the buffer plate is connected to the bottom surface of the buffer groove. A buffer plate is installed in the buffer groove. The structure of the buffer plate is in the shape of a "Ji" character. One end of the buffer plate is connected to the bottom surface of the buffer groove. After installing the top cover, both sides of the opening of the buffer plate are in contact with the top cover for supporting the top cover. The "Ji" character structure can effectively relieve the force and disperse the impact force to the base, thereby improving the impact resistance. Such a design can effectively improve the impact resistance.

[0009] Preferably, a plurality of groups of fitting plates are provided on the top cover. Each group of fitting plates includes a left plate and a right plate. The two fitting plates are respectively in contact with both sides of the buffer groove. A splicing block is installed on one side of the base, and a splicing groove is provided on the other side of the base. The splicing block corresponds to the splicing groove. When installing the top cover, it is necessary to align the top cover with the base. In order to quickly install the top cover, a plurality of groups of fitting plates are installed on the top cover. One group of fitting plates corresponds to one buffer groove. The left plate and the right plate of the fitting plate are respectively in contact with both side surfaces of the buffer groove. When placing the top cover, the position of the top cover can be quickly positioned through the correspondence between the fitting plate and the buffer groove for placement. Adjacent plastic wood boards are connected through the cooperation of the splicing block and the splicing groove. Such a design can quickly position the top cover.

[0010] Preferably, the fastening assembly includes a screw rod and an extension rod. One end of the screw rod passes through the right plate and contacts the side of the buffer groove. The other end of the screw rod has a threaded hole. One end of the extension rod is placed in the threaded hole and threadedly connected to the screw rod. The other end of the extension rod passes through the left plate and contacts the side of the buffer groove. The fastening assembly is used to connect the top cover and the base. The fastening assembly is installed between the left and right plates, and fastening assemblies are installed at both ends of the top cover to ensure reliable connection. One end of the screw rod of the fastening assembly is rotatably connected to the right plate. Since the screw rod and the extension rod are threadedly connected, the portion of the extension rod in the threaded hole extends out through the relative rotation of the screw rod and the extension rod. The other end of the extension rod passes through the left plate and contacts the side of the buffer groove. As the extension rod continues to extend, one end of the extension rod and one end of the screw rod are pressed against the base on both sides, thereby fixing the bonding plate in the buffer groove, thus completing the fixation of the top cover. This design can connect the top cover and the base.

[0011] Preferably, a screwing block is installed on the screwing rod, and a guide rod is installed at the end of the extension rod that is removed from the screwing rod. A guide groove is provided on the left plate, and the guide groove matches the guide rod. Since the space inside the buffer groove is small after the top cover is placed, making it difficult to rotate the screwing rod, a polygonal screwing block is installed on the screwing rod to facilitate rotation of the screwing rod and prevent the extension rod from rotating with the screwing rod. A guide rod is installed at the end of the extension rod that passes through the left plate, and the guide rod corresponds to the guide groove on the left plate, thereby ensuring that the guide plate can only move forward and will not rotate with the screwing rod. This design is beneficial for rotating the screwing rod.

[0012] Preferably, the top cover is provided with several evenly distributed fastening screws, and the buffer plate corresponds one-to-one with the fastening screws. The lower end of the fastening screw passes through the top cover and connects to the buffer plate. To prevent the top cover from bulging at the buffer groove and to prevent a reduction in the buffering effect due to non-contact with the buffer plate, several fastening screws are installed on the top cover, with two fastening screws corresponding to one buffer plate. The lower end of the fastening screw passes through the top cover and connects to the buffer plate, connecting both sides of the opening of the buffer plate to the top cover. This ensures that the buffer plate can promptly buffer the impact force received by the top cover. This design connects the top cover and the buffer plate.

[0013] The beneficial effects of this utility model are: by installing a buffer plate on the split plastic board to improve the impact resistance, the impact resistance is effectively improved, the top cover can be quickly positioned, the top cover and the base can be connected, it is convenient to rotate the screw rod, and the top cover and the buffer plate can be connected.

[0019] The following further describes the present utility model in conjunction with the attached drawings and specific implementation modes

[0020] As Figure 1 In the embodiment, an impact-resistant plastic wood board includes a base 1, an upper cover 2, a fastening component 3 and a buffer plate 4. A plurality of buffer grooves 5 are provided on the base 1. The upper cover 2 is connected to the base 1. Fastening components 3 are installed at both ends of the buffer groove 5. The upper cover 2 is connected to the base 1 through the fastening component 3. The buffer plate 4 is placed in the buffer groove 5. The lower end of the buffer plate 4 is connected to the base 1, and the upper end of the buffer plate 4 is connected to the upper cover 2

[0021] As Figure 2 Shown, a plurality of buffer plates 4 are evenly distributed in the buffer groove 5. The cross-sectional shape of the buffer plate 4 is in the shape of "Ji". One end of the opening of the buffer plate 4 contacts the bottom surface of the upper cover 2, and the other end of the buffer plate 4 is connected to the bottom surface of the buffer groove 5

[0022] As Figure 3 Shown, a plurality of groups of fitting plates 6 are provided on the upper cover 2. Each group of fitting plates 6 includes a left plate 7 and a right plate 8. The two fitting plates 6 are respectively fitted to both sides of the buffer groove 5. A splicing block 9 is installed on one side of the base 1, and a splicing groove 10 is provided on the other side of the base 1. The splicing block 9 corresponds to the splicing groove 10

[0023] As Figure 4 Shown, the fastening component 3 includes a screwing rod 11 and an extension rod 12. One end of the screwing rod 11 passes through the right plate 8 and contacts the side surface of the buffer groove 5. A threaded hole 13 is provided at the other end of the screwing rod 11. One end of the extension rod 12 is placed in the threaded hole 13 and is threadedly connected to the screwing rod 11. The other end of the extension rod 12 passes through the left plate 7 and contacts the side surface of the buffer groove 5

[0024] A screwing block 14 is installed on the screwing rod 11. A guide rod 15 is installed at one end of the extension rod 12 that is removed from the screwing rod 11. A guide groove 16 is provided on the left plate 7, and the guide groove 16 matches the guide rod 15.

[0025] The upper cover 2 is provided with several evenly distributed fastening screws 17, and the buffer plate 4 corresponds one-to-one with the fastening screws 17. The lower end of the fastening screw 17 passes through the upper cover 2 and is connected to the buffer plate 4.

[0026] During processing, the base 1 and the top cover 2 need to be processed separately. Then, the buffer plate 4 is evenly installed in the buffer groove 5 of the base 1 to complete the preparation work before installation. When installing the plastic board, the separately processed base 1 and the top cover 2 are connected. The top cover 2 is quickly installed by limiting the position of the bonding plate 6 and then placed on the base 1.

[0027] Then, the screw rods 11 at both ends of the buffer groove 5 are rotated. The screw rods 11 are rotated by the screw blocks 14 on the screw rods 11. Since the screw rods 11 are threadedly connected to the extension rods 12, the extension rods 12 extend linearly under the cooperation of the guide rods 15 and the guide grooves 16. The extended extension rods 12 will squeeze the inner wall of the buffer groove 5. Both ends of the fastening assembly 3 squeeze the side of the buffer, thereby fixing the upper cover 2 to the base 1. Then, the upper end of the buffer plate 5 is connected to the upper cover 2 by the fastening screws 17.

[0028] When the top cover 2 is impacted, the buffer plate 4 placed in the buffer groove 5 will release the impact force on the top cover 2 and distribute the impact force to the base 1, thereby improving the impact resistance of the plastic board.
