[0001] This invention relates to the field of wood-plastic composite flooring technology, specifically to a quick-assembly wood-plastic composite flooring assembly structure and assembly method that enables drilling-free assembly. Background Technology

[0002] Wood-plastic composite flooring is a new type of environmentally friendly wood-plastic composite material product. The lignin produced during the production of medium- and high-density fiberboard is added to recycled plastic and granulated to form wood-plastic composite material, which is then extruded to make wood-plastic flooring.

[0003] Chinese patent CN217782710U discloses a novel type of interlocking wood-plastic composite flooring, which includes several first wood-plastic composite floorings, second wood-plastic composite floorings, joists, first clips, second clips, and screws. First clips are installed inside adjacent first and second fixing ports. The bottom of the first clips is fixedly connected to the joists by screws. The first clips work with the joists to fix the first wood-plastic composite floorings and second wood-plastic composite floorings together.

[0004] While this patent addresses the aesthetic issues of the prior art to some extent, the buckles in this patent require screws to connect to the keel, necessitating drilling holes in the keel, which increases installation difficulty. Furthermore, the lack of connection between wood-plastic composite flooring units makes them prone to misalignment and displacement. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-assembly wood-plastic composite flooring assembly structure and assembly method that enables drilling-free assembly. By connecting the joists and the flooring simultaneously through interlocking blocks, the problems mentioned in the background art are solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-assembly wood-plastic flooring assembly structure that enables drilling-free assembly, comprising a connecting joist and a flooring body, wherein the upper surface of the connecting joist is covered with the flooring body, one end of the flooring body has a first engaging groove, the other end of the flooring body has a second engaging groove, a guide rod is provided in the second engaging groove, and an engaging block is sleeved on the guide rod, the engaging block engaging and connecting with the first engaging groove, the second engaging groove and the connecting joist simultaneously.

[0007] Preferably, the connecting keel includes a square base, a supporting plane, and a limiting inclined plane. One side of the upper end of the square base is fixedly connected to one side of the supporting plane, and the other side of the upper end of the square base is fixedly connected to the lower end of the limiting inclined plane. The upper end of the limiting inclined plane is fixedly connected to the lower surface of the supporting plane.

[0008] Preferably, a limiting protrusion is fixedly connected to the lower surface of one end of the supporting plane, and one of the inclined surfaces of the limiting protrusion is parallel to the limiting inclined surface.

[0009] Preferably, the lower end of the locking block is fixedly connected to a vertically arranged hook plate, and the lower end of the hook plate is fixedly connected to an oblique hook, which engages with the limiting protrusion.

[0010] Preferably, the locking block is an inclined frustum structure, with a spring groove on the locking block. A guide hole is provided at one end of the spring groove near the top of the locking block, and the guide hole is movably connected to a guide rod. The side of the spring groove near the surface of the floor body is a sealed structure.

[0011] Preferably, the guide rod is fixedly connected to a limiting plate at one end of the spring groove, and a support spring is sleeved on the end of the guide rod near the limiting plate. The two ends of the support spring are respectively connected to the limiting plate and the spring groove.

[0012] Preferably, the first engaging groove includes an mounting part, an engaging part, and a limiting block. The lower part of the mounting part is fixedly connected to the upper part of the engaging part. The limiting block is fixedly connected to the lower part of the mounting part. The lower end of the engaging part matches the lower end of the engaging block. The mounting part has an open structure at the lower end.

[0013] Preferably, a side wall slot is provided on the side wall of the floor body, and a side wall strip is fixedly connected to the side wall of the floor body opposite to the side wall slot. The side walls of two adjacent floor bodies are engaged and connected by the side wall slot and the side wall strip.

[0014] Preferably, the floor body has a weight-reducing through hole that penetrates the floor body and is flush with the upper surface of the floor body. The first locking groove and the second locking groove are embedded in the floor body.

[0015] Another technical problem to be solved by the present invention is to provide an assembly method for a quick-assembly wood-plastic flooring structure that enables drilling-free assembly, comprising the following steps:

[0016] S1: Lay the connecting joists at equal intervals according to the flooring area, and open the flooring body in a direction perpendicular to the connecting joists;

[0017] S2: The side walls of adjacent floor panels are connected by side wall slots and side wall strips;

[0018] S3: The ends of adjacent floor panels are fixed by interlocking blocks. At the same time, the interlocking blocks fix the connected floor panels to the connecting joists via hook plates, and the ends of the floor panels are laid on the connecting joists.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The side walls of adjacent floorboards are connected by a simple plug-in method, facilitating the installation of the floorboards. At the same time, the ends of adjacent floorboards are connected by snap-fit ​​blocks. The snap-fit ​​blocks themselves are inclined truncated cone structures. After engaging with the first snap-fit ​​groove, they cannot move horizontally or vertically, improving the firmness of the connection at the ends of the floorboards. Furthermore, the lower end of the snap-fit ​​block engages with the connecting joists via hook plates, eliminating the need to drill holes in the connecting joists to fix the floorboards. With the snap-fit ​​block in a fixed position, the hook plates are also prevented from detaching from the connecting joists. Thus, while connecting the ends of the floorboards, the entire floorboard can be fixed to the connecting joists, facilitating quick assembly. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the issue that existing clip-on systems require screws to connect to the joists, necessitating drilling into the joists and increasing installation difficulty, and the lack of interconnections between wood-plastic composite floorboards, which can lead to misalignment and displacement, please refer to [the relevant documentation / reference]. Figures 1-8 This embodiment provides the following technical solution:

[0032] In this embodiment, the quick-assembly wood-plastic flooring assembly structure that enables drilling-free installation includes a connecting joist 1 and a flooring body 2. The flooring body 2 is laid on the upper surface of the connecting joist 1. The connecting joist 1 includes a square base 11, a supporting plane 12, and a limiting inclined plane 13. The square base 11, the supporting plane 12, and the limiting inclined plane 13 are integrally formed. The square base 11 is connected to the mounting surface to fix the entire wood-plastic flooring. One side of the upper end of the square base 11 is fixedly connected to one side of the supporting plane 12. The supporting plane 12 is used to support the flooring body 2, and the joints of the flooring body 2 overlap with the supporting plane 12. The other side of the upper end of the square base 11 is fixedly connected to the lower end of the limiting inclined plane 13. The upper end of the limiting inclined plane 13 is fixedly connected to the lower surface of the supporting plane 12. An open space is formed between the limiting inclined plane 13 and the supporting plane 12. The locking block 3 is connected to the connecting joist 1 by locking with this open space.

[0033] In this embodiment, the support plane 12 is not flush with the square base 11, but has space to engage with the hook plate 31. A limiting protrusion 121 is fixedly connected to the lower surface of one end of the support plane 12, and one of the inclined surfaces of the limiting protrusion 121 is parallel to the limiting inclined surface 13.

[0034] In this embodiment, a vertically arranged hook plate 31 is fixedly connected to the lower end of the locking block 3, and an inclined hook 311 is fixedly connected to the lower end of the hook plate 31. The inclined hook 311 engages with the limiting protrusion 121 and is positioned between the limiting protrusion 121 and the limiting inclined surface 13. The inclined surface of the inclined hook 311 contacts the limiting protrusion 121 and the limiting inclined surface 13 respectively. During installation, the inclined hook 311 moves upward along the limiting inclined surface 13. Anti-slip textures or wedge-shaped textures can be provided on the limiting inclined surface 13 to prevent the inclined hook 311 from sliding downward. After installation, the inclined hook 311 engages with the limiting protrusion 121, and the inclined hook 311 restricts the horizontal movement of the hook plate 31. One side of the hook plate 31 abuts against the supporting plane 12, and the hook plate 31 is perpendicular to the outer wall of the square base 11. The hook plate 31 provides support for the locking block 3.

[0035] In this embodiment, the locking block 3 is an inclined frustum structure. The end of the locking block 3 connected to the second locking groove 22 has a smaller surface area, while the end of the locking block 3 with a larger surface area is engaged with the first locking groove 21. A spring groove 32 is provided on the locking block 3. A guide hole 321 is provided at the end of the spring groove 32 near the top of the locking block 3. The guide hole 321 is movably connected to the guide rod 23. The locking block 3 can move on the guide rod 23. The side of the spring groove 32 near the surface of the floor body 2 is a sealed structure. When the locking block 3 is connected to the floor body 2, the locking block 3 is located in the gap between the two floor bodies 2. The upper surface of the spring groove 32 is made into a sealed structure to prevent rainwater from entering the spring groove 32 and extend the service life of the spring.

[0036] In this embodiment, a first engaging groove 21 is provided at one end of the floor body 2, and a second engaging groove 22 is provided at the other end of the floor body 2. A guide rod 23 is provided in the second engaging groove 22, and an engaging block 3 is sleeved on the guide rod 23. The engaging block 3 engages and connects with the first engaging groove 21, the second engaging groove 22 and the connecting keel 1.

[0037] In this embodiment, a guide rod 23 is fixedly connected to a limiting plate 231 at one end of the spring groove 32. A support spring 232 is sleeved on the end of the guide rod 23 near the limiting plate 231. The two ends of the support spring 232 are respectively connected to the limiting plate 231 and the spring groove 32. Under the action of the support spring 232, the limiting plate 231 and the end of the spring groove 32 near the guide hole 321 are separated by a certain distance, thereby pushing the locking block 3 to overlap with the guide rod 23 at a larger position. Manually pulling the locking block 3 can cause the support spring 232 to retract, and the locking block 3 moves along the direction of the guide rod 23.

[0038] In this embodiment, the first engaging groove 21 includes an mounting part 211, an engaging part 212, and a limiting block 213. The lower oblique part of the mounting part 211 is fixedly connected to the upper oblique part of the engaging part 212. The limiting block 213 is fixedly connected to the lower position of the mounting part 211. The engaging part 212 matches the lower end of the engaging block 3. The mounting part 211 has an open structure at the lower end. During installation, the lower end of the engaging block 3 is inserted from the open position of the mounting part 211, that is, the maximum length and width position of the engaging block 3 is inserted from the mounting part 211. Then, the non-maximum length and width position of the engaging block 3 passes between the limiting blocks 213, and the engaging block 3 enters the groove. After entering the first engaging groove 21, the engaging block 3 is released and reset along the guide rod 23 under the action of the support spring 232. The engaging block 3 disengages from the mounting part 211 and fully enters the engaging part 212. The engaging part 212 and the lower end of the engaging block 3 are perfectly matched. Therefore, the lower end of the engaging block 3 abuts against the side wall of the engaging part 212. At the same time, the limiting block 213 limits the position of the lower end of the engaging block 3. The limiting block 213 and the engaging part 212 form a conical groove that matches the engaging block 3. The engaging block 3 cannot move in either the horizontal or vertical direction, thus realizing the end connection of the two floor bodies 2.

[0039] In this embodiment, a side wall slot 24 is provided on the side wall of the floor body 2, and a side wall strip 25 is fixedly connected to the side wall of the floor body 2 opposite to the side wall slot 24. The side walls of two adjacent floor bodies 2 are engaged and connected by the side wall slot 24 and the side wall strip 25. During installation, the side wall strip 25 on one floor body 2 is simultaneously connected to the side wall slot 24 on two adjacent floor bodies 2 in a staggered manner, which can connect multiple floor bodies 2 into an integral structure, thereby improving the overall stability.

[0040] In this embodiment, a weight-reducing through hole is provided on the floor body 2, the weight-reducing through hole penetrates the floor body 2, the upper surface of the floor body 2 is flush, the first locking groove 21 and the second locking groove 22 are embedded in the floor body 2, ensuring that the surface of the floor body 2 is flat after installation and does not affect the aesthetics.

[0041] To better demonstrate the assembly process of a drill-free, quick-assembly wood-plastic composite (WPC) flooring structure, this embodiment proposes an assembly method for such a structure, including the following steps:

[0042] According to the flooring area, the connecting joists 1 are laid at equal intervals. The flooring bodies 2 are laid in a direction perpendicular to the connecting joists 1, with one flooring body 2 laid on three connecting joists 1. The side walls of adjacent flooring bodies 2 are connected by side wall slots 24 and side wall strips 25. When connecting, insert the side wall strip 25 from one end of the side wall slot 24 and push it to the middle position of the side wall slot 24. The ends of adjacent flooring bodies 2 are fixed by inserting and locking blocks 3. At the same time, the locking blocks 3 fix the connected flooring bodies 2 to the connecting joists 1 through the hook plate 31. Lay the end position of the flooring body 2 on the connecting joists 1. Manually pull the locking blocks 3 out from the second locking slot 22 and insert them into the installation part 211. Release the locking blocks 3, the support spring 232 returns to its original position, and the locking blocks 3 and the locking part 212 are locked together. At the same time, the locking blocks 3 drive the hook plate 31 to move and engage with the limiting protrusion 121.

[0043] In summary, the side walls of adjacent floor panels 2 are connected by a simple plug-in method, which facilitates the installation of the floor panels 2. At the same time, the ends of adjacent floor panels 2 are connected by a snap-fit ​​block 3. The snap-fit ​​block 3 itself is a truncated cone structure with an incline. After it is engaged with the first snap-fit ​​groove 21, it cannot move horizontally or vertically, which improves the firmness of the connection at the ends of the floor panels 2. Furthermore, the lower end of the snap-fit ​​block 3 is hooked to the connecting joist 1 by a hook plate 31, which eliminates the need to drill holes in the connecting joist 1 to fix the floor panels 2. With the snap-fit ​​block 3 fixed in position, the hook plate 31 can also be prevented from detaching from the connecting joist 1. Thus, while connecting the ends of the floor panels 2, the entire floor panels can be fixed to the connecting joist 1, which facilitates quick assembly.
