Description

Technical Field

[0001] This utility model relates to the field of wood-plastic profiles, and in particular to a wood-plastic profile structure that is easy to process. Background Technology

[0002] Wood-plastic composite profiles are a composite material made primarily from low-value biomass fibers such as sawdust, wood chips, bamboo chips, rice husks, wheat straw, soybean husks, peanut shells, sugarcane bagasse, and cotton stalks, combined with plastics. It combines the advantages of both plant fibers and plastics, and has a wide range of applications, covering almost all fields of use for logs, plastics, PVC, aluminum alloys, and other similar composite materials.

[0003] Chinese Patent Publication No. CN207331981U discloses a wood-plastic profile connection structure, including a first wood-plastic profile, a second wood-plastic profile, and a connecting device. The first wood-plastic profile has a hollow groove, and the second wood-plastic profile has a dovetail groove formed on its surface. The connecting device includes a first insertion part and a second insertion part that are perpendicular to each other. The first insertion part is slidably disposed in the dovetail groove, which allows for easy connection between the two wood-plastic profiles. It has the advantages of convenient assembly and disassembly, reliable and stable connection, and can be reused multiple times, thus expanding the application range of wood-plastic profiles. However, the existing structure still has some shortcomings. When splicing the two sets of wood-plastic profiles, bolts are required, which makes the splicing process relatively complicated. Furthermore, the use of bolts for splicing can easily cause deviations in their overlapping positions. Therefore, we propose a wood-plastic profile structure that is easy to process to solve the above problems. Utility Model Content

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.

[0022] Please see Figure 1-4 In this utility model, a wood-plastic profile structure that is easy to process includes a curved board 1. The outer surface of the curved board 1 has a placement groove 2, and a hardened board 5 is placed inside the placement groove 2. The front of the curved board 1 has multiple through holes 7. Both ends of the curved board 1 have connecting grooves 9, and both ends of the curved board 1 are fixedly connected to connecting plates 10. Each connecting groove 9 is adapted to the connecting plate 10. Through the cooperation of the connecting grooves 9 and connecting plates 10 at both ends of the structure, two sets of wood-plastic profiles can be spliced ​​together through two connecting and fixing structures. During the splicing process, the splicing position of the two sets of wood-plastic profiles can be positioned by the cooperation of the inclined fitting plate 8 and the inclined fitting groove 6, so that they overlap more tightly. By installing the hardened board 5 at the corner of the structure, the service life of the profile can be improved.

[0023] The inner wall of the placement groove 2 has two slots 14, and the right side of the rigid plate 5 is fixedly connected to two plates 13. Each slot 14 is adapted to the plate 13. The inner wall of the placement groove 2 has two grooves 11, and each groove 11 contains glue. Through the cooperation of the slots 14 and plates 13, the rigid plate 5 can be installed more firmly. The grooves 11 make it easy to pour the glue in, preventing the rigid plate 5 from having gaps with the curved plate 1 due to the thickness of the glue.

[0024] Two protrusions 12 are fixedly connected to the right side of the rigid board 5. Each protrusion 12 extends into the interior of the groove 11 and is in contact with the glue. Multiple support grooves 3 are provided on the front side of the curved board 1. Multiple inclined plates 4 are fixedly connected to the inner wall of each support groove 3. Inclined fitting grooves 6 are provided at both ends of the curved board 1. Inclined fitting plates 8 are fixedly connected to both ends of the curved board 1. This can position the splicing position of the two sets of wood-plastic profiles and make them overlap more tightly.

[0025] The working principle of this utility model is as follows:

[0026] This easy-to-process wood-plastic profile structure is used by workers first taking out multiple wood-plastic profile structures, then placing two sets of wood-plastic profile structures together. With the cooperation of the connecting grooves 9 and connecting plates 10 at both ends of the two sets of wood-plastic profile structures, the two sets of wood-plastic profile structures can be spliced ​​together. Finally, after the splicing is completed, workers apply glue to the two grooves 11 in the curved board 1, take out the rigid board 5, and install it in the placement groove 2 with the cooperation of the two sets of clamping plates 13 and clamping grooves 14.
