Description

Technical Field

[0001] This utility model relates to the field of composite flooring, and in particular to a structurally stable composite flooring. Background Technology

[0002] Composite flooring, widely used in modern architectural decoration, is an important component of the flooring industry. It involves artificially altering the natural structure of the flooring material to achieve specific desired physical properties. Common types include engineered wood flooring and solid wood composite flooring.

[0003] Compared to traditional solid wood flooring, engineered wood flooring offers several significant advantages. First, in terms of cost-effectiveness, it achieves good decorative effects and performance at a relatively low cost. Second, it is easy to install, saving considerable labor and time costs. Third, its wear-resistant and durable properties allow it to maintain a good appearance and functionality for a longer period. Finally, its ease of maintenance makes daily use more worry-free for users.

[0004] In existing technologies, traditional composite flooring suffers from significant structural stability issues. Traditional composite flooring typically consists of multiple layers bonded together, primarily including a core layer, a surface layer, and a bottom layer. The core layer is usually composed of multiple wooden strips, currently held together primarily by adhesive. However, adhesive bonding has obvious drawbacks; over long-term use, the adhesive gradually ages, leading to a weakening of its bonding effect. As the adhesive ages, the gaps between adjacent wooden strips gradually increase, affecting not only the flooring's appearance but also making the adhesive within the structure more susceptible to contact with air and moisture, accelerating the aging process. Eventually, the entire composite flooring structure becomes highly unstable, affecting its normal use and even posing safety hazards. Utility Model Content

[0005] The main objective of this invention is to provide a structurally stable composite floor that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A structurally stable composite floor includes a panel and a base plate. A core layer is provided between the panel and the base plate, and the core layer is composed of several core boards. Adjacent core boards are fixedly connected together by a connecting mechanism, which includes a flip plate, a fixed rod, a spring, a movable plate, and a latch. A flip plate is movably connected to one side of each end of the core board via a rotating rod. A set of symmetrical fixed rods is fixedly connected to the inner wall of the front end of the flip plate. The spring is sleeved on the outside of the fixed rod. The movable plate is movably connected to the fixed rod through a connecting hole on its side wall and is fixedly connected to one end of the spring. The latch is fixedly connected to the side wall of the movable plate. Reinforcing mechanisms are also provided between the panel and the core layer, and between the core layer and the base plate. The reinforcing mechanisms include a frame and pearl cotton. Two frames are fixedly connected between the panel and the core layer and between the base plate and the core layer via longitudinal dovetail strips on the upper and lower surfaces, respectively. Pearl cotton is filled inside the frames.

[0008] Optionally, a number of horizontal strips are fixedly installed inside the frame, and pearl cotton is fixedly filled inside the frame between adjacent horizontal strips. A number of longitudinal dovetail strips are also fixedly installed on the top and bottom surfaces of the frame.

[0009] Optionally, dovetail grooves corresponding to the longitudinal dovetail strips are respectively formed between the opposing walls of the panel and the core board, and between the opposing walls of the bottom plate and the core board, and the longitudinal dovetail strips are inserted and installed in the dovetail grooves.

[0010] Optionally, the core board has left grooves on the left side of its front and rear ends, and a positioning block is fixedly installed in the groove of the left groove. The positioning block has a slot on its side wall.

[0011] Optionally, the front and rear end walls of the core plate are respectively provided with right grooves, and the top and bottom surfaces of the right grooves are respectively provided with rotating holes.

[0012] Optionally, a set of symmetrical rotating rods are fixedly installed on the left side of the flip plate, and the rotating rods are movably installed in the rotating holes. A positioning port corresponding to the positioning block is opened on the front wall of the flip plate, and a movable port is also opened on the right side of the front wall of the flip plate located at the positioning port. A connecting port is opened between the positioning port and the movable port, and a set of symmetrical fixing rods are fixedly installed inside the movable port. A spring is fitted on the outside of the fixing rods. A set of symmetrical connecting holes is opened on the side wall of the movable plate, and the movable plate is movably installed together with the fixing rods through the connecting holes. The left end of the spring is fixedly installed together with the right side wall of the movable plate, and the right end of the spring is fixedly installed together with the inner wall of the movable port. The latch is fixedly installed on the left side wall of the movable plate and passes through the connecting port and is inserted into the latch.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, adjacent core boards are fixedly connected by a unique connecting mechanism. The flip plate in the connecting mechanism can rotate flexibly around the rotating rod. When adjacent core boards are spliced, the flip plate can be flipped. The movable plate can move flexibly under the cooperation of the spring and the fixed rod. The latch can be inserted into the slot of the positioning block under the drive of the movable plate. This connection method not only avoids the connection failure problem caused by aging of traditional glue connection, but also has a tight connection, which can effectively prevent the gap between adjacent core boards from increasing, greatly improving the stability and integrity of the core layer structure, thereby enhancing the overall structural stability of the composite floor.

[0015] Meanwhile, the reinforcing mechanisms between the panel and the core layer, as well as between the core layer and the bottom plate, are connected by longitudinal dovetail strips on the frame and dovetail grooves on the panel, core plate, and bottom plate, making the connection between each layer more solid and less prone to interlayer displacement or separation. Furthermore, the pearl cotton filling in the frame and the horizontal strips further enhance the cushioning performance and structural strength of the composite flooring. Pearl cotton has good elasticity and cushioning effect, which can effectively absorb and disperse the pressure and impact on the ground, reduce the damage to the floor caused by external forces, and extend the service life of the flooring. The horizontal strips play a role in supporting and strengthening the frame structure, so that the frame can still maintain good shape and strength after being filled with pearl cotton.

[0016] Therefore, through the synergistic effect of the connecting mechanism and the reinforcing mechanism, the safety hazards that may be caused by the structural instability of traditional composite flooring are effectively solved, ensuring the safety, reliability and structural stability of composite flooring during use, and making it suitable for various building environments and usage scenarios.

[0025] like Figure 1 - Figure 5 As shown, a structurally stable composite floor includes a front panel 1 and a back panel 2. A core layer 3 is provided between the front panel 1 and the back panel 2, and the core layer 3 is composed of several core boards 4. Adjacent core boards 4 are fixedly connected together by a connecting mechanism 5. The connecting mechanism 5 includes a flip plate 17, a fixing rod 22, a spring 23, a movable plate 24, and a latch 26. One end of each core board 4 is movably connected to a flip plate 17 via a rotating rod 18. A set of symmetrical fixing rods 22 are fixedly connected to the front wall of the flip plate 17. The spring 23 is sleeved on... Outside the fixed rod 22, the movable plate 24 is movably connected to the fixed rod 22 through the connecting hole 25 on the side wall and fixedly connected to one end of the spring 23. The latch 26 is fixedly connected to the side wall of the movable plate 24. A reinforcing mechanism 6 is provided between the panel 1 and the core layer 3 and between the core layer 3 and the bottom plate 2. The reinforcing mechanism 6 includes a frame 7 and pearl cotton 9. The two frames 7 are fixedly connected between the panel 1 and the core layer 3 and between the bottom plate 2 and the core layer 3 through the upper and lower longitudinal dovetail strips 10, respectively. The pearl cotton 9 is filled inside the frame 7.

[0026] like Figure 2 and Figure 3 As shown, several horizontal strips 8 are fixedly installed inside the frame 7, and pearl cotton 9 is fixedly filled between adjacent horizontal strips 8. Several longitudinal dovetail strips 10 are also fixedly installed on the top and bottom surfaces of the frame 7. The horizontal strips 8 provide skeletal support for the frame 7, enhancing its overall structural strength and stability, and preventing the frame 7 from deforming under stress. The pearl cotton 9 has good elasticity and cushioning properties, and when filled between adjacent horizontal strips 8, it can effectively absorb and disperse the impact force transmitted from the outside. The longitudinal dovetail strips 10 are used to connect with other components. Their special dovetail shape can achieve a tight and stable connection, which improves the overall stability and cushioning capacity of the frame 7. During the use of composite flooring, when subjected to pressure or impact, the horizontal strips 8 and pearl cotton 9 work together to reduce damage to other parts of the flooring, extend the service life of the composite flooring, and improve the stability of the composite flooring.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, dovetail grooves 11 corresponding to the longitudinal dovetail strips 10 are respectively opened between the opposite walls of the panel 1 and the core board 4, and between the opposite walls of the bottom plate 2 and the core board 4. The longitudinal dovetail strips 10 are inserted into the dovetail grooves 11. The special shape of the dovetail strips 10 allows them to form a good limiting effect in both the horizontal and vertical directions after being inserted into the dovetail grooves 11. Through this connection method, the panel 1, the core board 4 and the bottom plate 2 can be tightly connected, which enhances the connection stability between the layers of the composite floor. In daily use, even if subjected to external forces, the layers are not prone to misalignment or delamination, thus ensuring the overall performance of the composite floor.

[0028] like Figure 4 As shown, left grooves 12 are respectively provided on the left side of the front and rear ends of the core board 4, and positioning blocks 13 are fixedly installed in the grooves of the left grooves 12. The side wall of the positioning block 13 is provided with a slot 14. The left grooves 12 provide installation space for the positioning block 13. The slots 14 on the positioning block 13 are used for engaging with other components. The main function of the positioning block 13 is to provide accurate positioning and a fixed foundation for the connection between adjacent core boards 4.

[0029] like Figure 4 and Figure 5 As shown, right grooves 15 are respectively provided on the right side of the front and rear end walls of the core board 4, and rotating holes 16 are respectively provided on the top and bottom sides of the groove of the right groove 15. By rotating the rotating rod 18 in the rotating hole 16, the flipping and snapping action of the connecting parts can be realized, which facilitates the splicing and fixing of adjacent core boards 4.

[0030] like Figure 4 and Figure 5 As shown, a set of symmetrical rotating rods 18 are fixedly installed on the left side of the flip plate 17, and the rotating rods 18 are movably installed in the rotating hole 16. A positioning port 19 corresponding to the positioning block 13 is opened on the front wall of the flip plate 17, and a movable port 20 is also opened on the right side of the front wall of the flip plate 17, located at the positioning port 19. A connecting port 21 is opened between the positioning port 19 and the movable port 20, and a set of symmetrical fixing rods 22 are fixedly installed inside the movable port 20. A spring 23 is fitted on the outside of the fixing rods 22. A set of symmetrical connecting holes 25 are opened on the side wall of the movable plate 24, and the movable plate 24 is movably installed together with the fixing rods 22 through the connecting holes 25. The left end of the spring 23 is fixedly installed together with the right side wall of the movable plate 24, and the right end of the spring 23 is fixedly installed together with the right side wall of the movable plate 24. The movable plate 24 is fixedly installed on the inner wall of the movable opening 20. The latch 26 is fixedly installed on the left side wall of the movable plate 24 and passes through the connecting opening 21 and is inserted into the slot 14. The rotating rod 18 rotates in the rotating hole 16, so that the flip plate 17 can flip around the rotating point. The movable plate 24 slides on the fixed rod 22 through the connecting hole 25. The extension and contraction of the spring 23 provides elastic force for the movable plate 24. When adjacent core plates 4 are spliced, the flip plate 17 flips, and the positioning opening 19 cooperates with the positioning block 13 to determine the position. At the same time, under the action of the spring 23, the movable plate 24 drives the latch 26 to pass through the connecting opening 21 and insert into the slot 14, realizing the snap-fit ​​fixation of adjacent core plates 4, improving the efficiency and stability of splicing adjacent core plates 4, thereby enhancing the overall structural stability of the composite floor core layer.

[0031] The specific operating principle of the composite flooring consisting of panel 1, base plate 2, and core layer 3, in conjunction with the connecting mechanism 5 and the reinforcing mechanism 6, is as follows:

[0032] Several core boards 4 are inserted into adjacent frames 7 through dovetail grooves 11 on the top and bottom surfaces, and the longitudinal dovetail strips 10 on the frames 7 are correspondingly inserted into the dovetail grooves 11, so that the core layer 3 of the composite floor is formed by the several core boards 4. The movable plate 24 is pushed to the right, so that the movable plate 24 moves to the right through the connecting hole 25 along the fixed rod 22 in the movable opening 20, and forces the spring 23 fitted on the fixed rod 22 to perform a tightening operation until the latch 26 on the left side wall of the movable plate 24 moves from the positioning opening 19 to the connecting opening 21. After that, the pushing force on the movable plate 24 is maintained and the flipping plate 17 is flipped. The rotating rod 18 installed on the left side of the flipping plate 17 will rotate in the rotating hole 16 opened in the right groove 15. Until the flip plate 17 is flipped so that it is laterally placed in the left groove 12 on one side of the adjacent core board 4, the positioning block 13 installed in the left groove 12 will be inserted into the positioning hole 19 on the front wall of the flip plate 17. Then, the pushing force on the movable plate 24 is released, and the spring 23 will perform an elastic recovery extension operation, pushing the movable plate 24 to the left. The straight latch 26 passes through the connecting hole 21 and is inserted into the latch 14 on the side wall of the positioning block 13. Therefore, the adjacent core boards 4 can be further quickly connected and fixed together. This avoids the aging problem of traditional glue connections in composite flooring, makes the core boards 4 firmly connected, prevents the gap between adjacent core boards 4 from increasing, and improves the stability and integrity of the core layer 3. Finally, The panel 1 and base plate 2 are respectively installed onto the corresponding frame 7, so that the longitudinal dovetail strips 10 on the frame 7 are inserted into the dovetail grooves 11 opened on the opposite walls of the panel 1 and base plate 2. This ensures that the layers of the composite flooring are firmly connected, preventing interlayer displacement or separation. Simultaneously, the pearl cotton 9 filling between the transverse strips 8 inside the frame 7 buffers and absorbs energy, reducing damage to the flooring and extending its service life. Under the action of the mesh-like structure formed by the frame 7, transverse strips 8, and longitudinal dovetail strips 10, an integrated load-bearing structure is formed, playing a crucial role in internal reinforcement within the composite flooring. When the composite flooring is subjected to external pressure, this mesh-like structure can evenly distribute the pressure to various parts, preventing excessive local pressure from causing damage. Furthermore, the filling... The pearl cotton 9 filled inside the frame 7 has good elasticity and cushioning properties, which can further absorb and disperse pressure, reducing the impact on the floor structure. On the one hand, it improves the load-bearing capacity of the composite floor, enabling it to withstand greater pressure and weight, making it suitable for places with high traffic or high load-bearing requirements. On the other hand, this structure enhances the composite floor's resistance to deformation, making it less prone to bending and cracking during long-term use, thus extending the floor's service life. In addition, the entire composite floor installation process is simple, the structure is stable and reliable, and it does not require frequent maintenance during use, reducing usage costs and providing users with a more comfortable, safe, and durable user experience. It is widely applicable to various building environments and usage scenarios.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
