Description

Technical Field

[0001] This invention relates to the technical field of wood flooring installation and connection structures, specifically a snap-lock connection system. Background Technology

[0002] The flat-lock connection system is a simple interlocking mortise and tenon structure that restricts the longitudinal displacement of two adjacent floorboards through the interlocking of the male and female tenons. Since the flat-lock cannot restrict lateral displacement, it is often used in conjunction with nails and joists or glue to restrict lateral displacement (limiting contraction joints), making the installation process relatively cumbersome. The snap-lock connection system is a more complex interlocking mortise and tenon structure that restricts both longitudinal and lateral displacement of two adjacent floorboards by adding protrusions and grooves to the male and female tenons. However, due to its structural characteristics, the snap-lock connection system must lock downwards at a certain angle, requiring both locking edges to be straight, and the splicing method to be sequential longitudinal splicing, making it unsuitable for splicing irregularly shaped floorboards. Furthermore, the snap-lock connection system consumes more materials.

[0003] In summary, there is a lack of existing technologies that offer a relatively wide range of applicable flooring types, are easy to install, and have relatively low material waste during the connection process. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a snap-lock connection system that is easy to install, applicable to irregular flooring installation, and has a relatively wide range of applications. It solves the shortcomings of traditional snap-lock flooring that requires nailing and gluing, solves the problem of installation difficulties caused by tilting the flooring during the finishing stage, and solves the problem that snap-lock connections cannot be achieved in irregular flooring such as herringbone and parquet patterns. Furthermore, it significantly improves the yield of flooring blanks and the utilization rate of wood.

[0005] To achieve the above objectives, embodiments of the present invention provide a locking buckle connection system, including a floor panel body, a male tenon module, and a female tenon module. At least one of the top and bottom surfaces of the male tenon module is provided with a locking component. The female tenon module is provided with a locking groove that mates with the locking component. The locking component includes at least a first side near the end of the male tenon module and a second side near the floor panel body. The first side and the second side are angled together. The locking groove includes at least a first groove edge that mates with the first side edge and a second groove edge that mates with the second side edge.

[0006] With the above structure, through the setting of the locking component and the locking groove, the male tenon module is inserted laterally into the female tenon module. The locking component utilizes the toughness of the wood to deform and simultaneously pushes up the female tenon module. Then, the locking component is inserted into the locking groove, and through the interlocking assembly relationship between the two, lateral restraint is provided between adjacent floorboards. Therefore, the lock-and-hook connection system of this application does not require the use of nails, joists, or glue. During assembly, no tilting angle is required; horizontal insertion and interlocking are sufficient. The installation is relatively simple, suitable for irregularly shaped floorboards, and has a relatively wide range of applications. At the same time, its main structure is still a flat-lock connection system, so the material loss in making the lock-and-hook connection system is only 60%-65% of that of the lock-and-hook connection system, which improves the yield of floorboards and the utilization rate of wood.

[0007] Preferably, the locking component is disposed near the side of the ground plate body.

[0008] Preferably, the first side forms an angle of 115°-140° with the surface of the tenon module on the same side.

[0009] Preferably, the locking component further includes a locking top surface connecting the first side and the second side, and the locking groove further includes a groove bottom surface corresponding to the locking top surface, wherein the width of the locking top surface is 45%-55% of the width of the groove bottom surface.

[0010] Preferably, after assembly, there is a gap between the first side and the first groove edge, and the second side is in contact with the second groove edge.

[0011] Preferably, the gap is 0.1mm-0.3mm.

[0012] Preferably, the top surface of the tenon module (200) is provided with the locking component (400).

[0013] Preferably, the second side forms an angle of 135°-137° with the main body of the ground plate.

[0014] Preferably, the second side and the second groove side are parallel.

[0015] Preferably, the second side edge and the second groove edge have an included angle of 2.4°-4°.

[0016] Preferably, the second side forms an angle of 132.7°-134.3° with the main body of the ground plate.

[0017] Preferably, the top and bottom surfaces of the tenon module are provided with the protruding locking components, and the two protruding locking components are mirror images of the center plane of the thickness of the floor slab body.

[0018] Preferably, the male tenon module has protruding locking components on both its top and bottom surfaces. The protruding locking component on the top surface of the male tenon module includes an upper first side, an upper second side, and an upper protruding locking top surface. The protruding locking component on the bottom surface of the male tenon module includes a lower first side, a lower second side, and a lower protruding locking top surface. The upper second side forms an angle of 132.7°-134.3° with the body of the floor slab. The lower first side forms an angle of 132.7°-134.3° with the surface of the male tenon module on its side. The upper second side and the upper second groove edge have an included angle of 2.4°-4°. The lower first side and the lower first groove edge have an included angle of 2.4°-4°.

[0019] Preferably, the bottom surface of the male tenon module near its end is recessed upward to extend the lower first side.

[0020] Preferably, the tenon length of the male tenon module is 4mm-5mm.

[0021] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Its installation is relatively simple, and it can be used for irregular flooring installation. It has a relatively wide range of applications. It can solve the shortcomings of traditional flat-lock flooring that requires nailing and gluing for installation. It can solve the problem of installation difficulties caused by tilting the flooring when finishing the installation of click flooring. It can solve the problem of not being able to achieve the click connection when assembling irregular flooring such as herringbone and parquet. In addition, the yield of flooring blanks and the utilization rate of wood are greatly improved.

[0023] 2. In the preferred technical solution, there is a gap between the first side and the first groove edge, while the second side and the second groove edge are in contact. Thus, after the male tenon module is inserted into the female tenon module, the limiting relationship between the second side and the second groove edge can achieve the function of reserving the installation gap of the floor tile, eliminating the need for inserts and further improving the installation efficiency of the floor.

[0024] 3. A preferred technical solution is that, by adjusting the tilt angle of the second side in conjunction with the gap between the first side and the first groove edge, when two adjacent floor tiles slightly deflect downwards around the joint, the second side and the second groove edge disengage, effectively avoiding the risk of increased foot noise caused by the protruding locking component and the protruding locking groove.

[0025] 4. A preferred technical solution, by defining the fit relationship between the lower first side and the lower first groove, and the fit relationship between the upper second side and the upper second groove, ensures that when the floor slab expands and arches, the lower first side and the lower first groove, and the upper second side and the upper second groove, simultaneously contact each other, forming a contact surface at a 45° angle to the upward arching force. The simultaneous action of these two contact surfaces at a 45° angle to the upward arching force enhances the connection force between the male tenon module and the female tenon module, shortens the tenon length of the male tenon module and the groove depth of the female tenon module, further improving the yield of floor slabs and the utilization rate of timber.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0041] Example 1: Refer to Figure 1 The lock-on fastener system shown is formed on the side of the periphery of the floor slab body 100 by milling, and includes a male tenon module 200 and a female tenon module 300. The top surface of the male tenon module 200 is provided with a locking component 400, and the inner wall of the tenon of the female tenon module 300 is provided with a locking groove 500 that mates with the locking component 400.

[0042] The locking component 400 includes a first side 410 near the end of the tenon module 200 and a second side 420 near the floor panel body 100. The first side 410 and the second side 420 are set at an angle. The locking groove 500 has a first groove edge 510 that mates with the first side 410 and a second groove edge 520 that mates with the second side 420.

[0043] With the above structure, through the setting of the locking component 400 and the locking groove 500, the male tenon module 200 is inserted laterally into the female tenon module 300. Due to the toughness of the wood, the locking component 400 itself undergoes a certain deformation and simultaneously pushes up the upper and lower tenons of the female tenon module 300. Then the locking component 400 is inserted into the locking groove 500, and through the interlocking assembly relationship between the two, lateral restraint is provided between the adjacent floor slab bodies 100. Therefore, the lock-and-hook connection system of this application does not require the use of nails, joists, or glue. During assembly, it does not require tilting at a certain angle; it can be completed simply by horizontal insertion and snapping. The installation is relatively simple and can be applied to irregularly shaped flooring with a relatively wide range of applications. At the same time, its main structure is still a lock-and-hook connection system. Therefore, the material loss in making the lock-and-hook connection system is only 60%-65% of that of the lock-and-hook connection system. For example, a 130mm wide wooden blank can only be processed into flooring with a lock-and-hook connection system width of 118mm, while it can be processed into flooring with a lock-and-hook connection system width of 122mm, which improves the yield of flooring planks and the utilization rate of wood.

[0044] Reference Figure 2 As shown, the locking component 400 is positioned near the side of the floor slab body 100, and the locking groove 500 is positioned near the end of the tenon module 300. This design prevents damage to the locking component 400 during transport, reduces the insertion stroke requiring deformation of the locking component 400 itself and the expansion of the tenon module 300, and ensures the structural integrity of the locking component 400 and the locking groove 500.

[0045] Preferably, the first side 410 forms an angle of 115°-140° (e.g., 120°) with the surface of the male tenon module 200 on the same side, and the second side 420 forms an angle of 135°-137° (e.g., 135°) with the floor panel body 100. After assembly, there is a gap of 0.1mm-0.3mm (e.g., 0.2mm) between the first side 410 and the first groove edge 510, and the second side 420 contacts the second groove edge 520. In this embodiment, the second side 420 and the second groove edge 520 are parallel and in close contact. In the prior art, inserts need to be inserted between adjacent floor panel bodies 100 to ensure that a predetermined installation gap (generally 0.1mm-0.3mm) is reserved between adjacent floor panel bodies 100. With the constraints of the above structure, after the male tenon module 200 is inserted into the female tenon module 300, the second side 420 and the second groove 520 can be used to reserve the installation gap of the floor tile body 100, without the need for inserts, which further improves the efficiency of floor installation.

[0046] When the floor panel body 100 contracts, the limiting relationship between the second side 420 and the second groove edge 520 restricts the floor panel body 100 from moving away from each other, ensuring that the installation gap is always maintained between them. In particular, when the second side 420 forms an angle of 135°-137° with the floor panel body 100, the contact surface between them forms a self-locking angle of approximately 45° with the tendency force of the floor panel body 100 to move away from each other, which can improve the limiting effect of the second side 420 and the second groove edge 520.

[0047] When the floor slab body 100 expands, the tenon length of the male tenon module 200, which is 7mm-8mm, is generally sufficient to prevent the male tenon module 200 from coming out of the female tenon module 300 when the floor slab body 100 expands and arches.

[0048] When stepping on the connection point of the two 100-meter-long floor slabs, refer to... Figure 3 As shown, when two adjacent floor slabs 100 slightly deflect downwards about the splicing point (statistically, the deflection angle is about 0.5°-1°), the second side 420 and the second groove edge 520 will change from contact to discontinuation, thus effectively avoiding the risk of foot noise caused by the setting of the locking component and the locking groove.

[0049] Example 2: The difference between Example 2 and Example 1 is that, referring to... Figure 4 As shown, both the top and bottom surfaces of the tenon module 200 are provided with locking components 400, and the structures of the two locking components 400 are mirror images of the center plane of the thickness of the floor slab body 100. The positional relationship between the second side edge and the second groove edge of the locking buckle connection system in Embodiment 2 when a stepping deflection occurs is referenced. Figure 5 As shown, it can be understood that the second side and the second groove edge in this embodiment have also moved away from each other.

[0050] Example 3: The difference between Example 3 and Example 2 is that, referring to... Figure 6 As shown, the locking component 400 also includes a locking top surface 430 connecting the first side 410 and the second side 420, and the locking groove 500 also includes a groove bottom surface 530 corresponding to the locking top surface 430. The width of the locking top surface 430 is 45%-55% (e.g., 50%) of the width of the groove bottom surface 530. The locking top surface 430 can alleviate the pressure on the top surface of the locking component 400 when the locking component 400 pushes the tenon module 300, and avoid damage to the structure of the locking component 400 during insertion.

[0051] Example 4: The difference between Example 4 and Example 3 is that, referring to... Figure 7As shown, the two second side edges 420 on the top and bottom surfaces of the tenon module 200 are at an angle of 132.7°-134.3° to the floor plate body 100, and the two second side edges 420 and their corresponding second groove edges 520 have an included angle of 2.4°-4°, that is, the two second groove edges 520 are at an angle of 135.3°-136.7° to the floor plate body 100.

[0052] When the floor slab body 100 contracts, the angle between the second side 420, the second groove edge 520, and the floor slab body 100 decreases. Through long-term production practice, the inventors have found that this angle is approximately 0.2°-0.5°. After the second side 420 and the second groove edge 520 receive tension from adjacent floor slab bodies 100, the second side 420 undergoes a slight deformation, partially contacting the second groove edge 520. The angle of inclination of this partially contacting surface is smaller than when the contraction does not occur; that is, the contact surfaces of the two edges 420 and 520 are more vertical. This more effectively limits the risk of the male tenon module 200 detaching from the female tenon module 300 due to the contraction of the floor slab body 100.

[0053] When the floor slab body 100 expands, the second side 420 on the top surface of the tenon module 200 first tilts at a larger angle due to the expansion (statistically, the angle increases by about 0.2°-0.3°), and then arches again due to the mutual compression between adjacent floor slab bodies 100, deflecting clockwise at the angle shown in the figure (statistically, the deflection angle is about 0.5°-2°); the corresponding second groove edge 520 first expands at an angle of about 0.2°-0.3° due to the expansion, and then deflects counterclockwise by about 0.5°-2°. Therefore, by limiting the second side 420 located on the top surface of the male tenon module 200 to form an angle of 132.7°-134.3° with the floor plate body 100, and the corresponding second groove edge 520 to form an angle of 135.3°-136.7° with the floor plate body 100, in the event of expansion and arching, the second side 420 and the second groove edge can simultaneously reach a contact surface with a relative upward arching force of 45°, which can improve the connection force between the male tenon module and the female tenon module.

[0054] Example 5: The difference between Example 5 and Example 4 is that, referring to... Figure 8 , Figure 9 , Figure 10 As shown, the top and bottom surfaces of the tenon module 200 are provided with locking components 400. The locking component 400 on the top surface of the tenon module 200 includes an upper first side 410a, an upper second side 420a, and an upper locking top surface 430a. The locking component 400 on the bottom surface of the tenon module 200 includes a lower first side 410b, a lower second side 420b, and a lower locking top surface 430b.

[0055] The upper second side 420a forms an angle α1 of 132.7°-134.3° with the base plate body 100, the lower first side 410b forms an angle β1 of 132.7°-134.3° with the surface of the male tenon module 200 on the same side, the upper second side 420a and the upper second groove edge 520a have an included angle α2 of 2.4°-4°, and the lower first side 410b and the lower first groove edge 510b have an included angle β2 of 2.4°-4°.

[0056] Reference Figure 11 As shown, the locking buckle connection system of this embodiment undergoes deformation under stepping and shrinking conditions similar to those described above.

[0057] When the earth's tectonic plate expands by 100, refer to Figure 12 As shown, α1 and β1 first expand in angle by about 0.2°-0.3° due to expansion, and then deflect clockwise by about 0.5°-2°. Similarly, α2 and β2 first expand in angle by about 0.2°-0.3° due to expansion, and then deflect clockwise by about 0.5°-2°. This results in surface contact between the upper second side 420a and the upper second groove side 520a, the lower first side 410b and the lower first groove side 510b. The contact surfaces A and B are approximately 45° to the direction of the arching tendency force F. At this point, the contact surfaces A and B self-lock with the tendency force F. After being self-locked by the two contact surfaces A and B, the limiting force of the locking component 400 and the locking groove 500 on the upward displacement of the ground plate body 100 can be increased more effectively. At this point, the male tenon module 200 does not completely disengage from the female tenon module 300, which is not entirely dependent on the tenon length, thus reducing the tenon length of the male tenon module 200 to a certain extent.

[0058] Preferably, the bottom surface of the male tenon module 200 near its end is recessed upwards to extend the lower first side 410b. That is, with the thickness center plane L of the male tenon module 200 as the center, the thickness of the lower part of the male tenon module 200 is 40%-50% of the thickness of its upper part, allowing the lower first side 410b to be extended. This increases the effective contact area of ​​the lower first side 410b without increasing the protrusion height of the locking component 400. Furthermore, it shortens the tenon length of the male tenon module 200; for example, the tenon length of the male tenon module 200 only needs to be 4mm-5mm to achieve the tenon length of 7mm-8mm in the prior art. This facilitates the release of the male tenon module 200 from the female tenon module 300 during arching, further improving the yield of floor planks and the utilization rate of timber.
