[0002] There are currently two ways to assemble the locking series of herringbone flooring or wall panels.

[0003] The first type requires separate A and B panels, which are assembled alternately in two directions. During production, half of the inverted grooves in this series require two processes: vertical production and then horizontal production. Packaging requires one A panel and one B panel. User installation also requires alternating A and B panels in a herringbone pattern. This complex preparation, installation, and transportation process significantly increases costs.

[0004] The second type of herringbone product requires the use of a jumping tool to process both ends of the longitudinal groove of the floor during production. However, the jumping position error of this product is relatively large, the tensile index is relatively small, and the production efficiency is low.

[0005] Furthermore, the locks of the existing herringbone panels need to be snapped together and installed, which brings a lot of inconvenience to the installation process. Utility Model Content

In the prior art of the herringbone-shaped locking plate in Figure 2, one of the longer sides is provided with a first locking structure A as shown in Figure 1, the middle portion of the other opposite longer side is provided with a second locking structure B as shown in Figure 1, both shorter sides are provided with a third locking structure C as shown in Figure 1, and both sides of the other opposite longer side are provided with a fourth locking structure D as shown in Figure 1. Because different locking structures are provided on the longer sides, this structure requires the use of a jump cutter, which has poor stability and is difficult to produce. Moreover, the third locking structure C and the fourth locking structure D are interlocked, resulting in weak locking force.

[0035] Please refer to Figures 3 to 5 and Figure 12. This embodiment shows a herringbone interlocking plate unit having a pair of parallel long sides and a pair of parallel short sides 3. The pair of long sides are a first side 1 and a second side 2, respectively. The first side and the second side are provided with a first snap-fit ​​structure 4 and a second snap-fit ​​structure 5, respectively. Each short side is provided with a third snap-fit ​​structure 6. The first snap-fit ​​structure is engageable with the second snap-fit ​​structure and the third snap-fit ​​structure in the horizontal direction, and the third snap-fit ​​structure is engageable with the second snap-fit ​​structure in the horizontal direction. The long side is longer than the short side. The dimensions of the long and short sides are set according to the needs of laying the herringbone floor.

[0036] As shown in Figure 5, a cross-sectional view of the third snap-fit ​​structure 6 is shown. The third snap-fit ​​structure 6 extends along the short side and includes a horizontally protruding first locking tongue 64, a downwardly opening first locking groove 63, a downwardly opening second locking groove 62, and a downwardly protruding second locking tongue 62. "Downward" refers to the direction perpendicular to the horizontal direction of the figure and toward the paved surface. The first locking tongue, first locking groove, second locking tongue, and second locking groove can be arranged in order from top to bottom. In other embodiments, they can also be arranged from bottom to top.

[0037] As shown in Figure 13, from top to bottom are schematic diagrams of the plates before and after they are engaged. The black solid arrow indicates the direction of force application. The engaging directions between the second engaging structure 5 and the third engaging structure 6, and between the first engaging structure 4 and the third engaging structure 6 are all horizontally force-engaged, thereby locking and fastening.

[0038] Optionally, a pit 65 is provided above the first locking tongue, and the side of the second locking groove close to the first locking tongue is an inclined side, and the side of the second locking groove close to the second locking tongue can also be an inclined side to facilitate sliding in and fastening.

[0039] Optionally, in order to further facilitate installation and secure the lock, the protrusion of the second locking tongue gradually increases in height from close to the first locking groove to close to the second locking groove (away from the first locking groove).

[0040] Optionally, the depth of the first locking groove is greater than the depth of the second locking groove.

[0041] As shown in Figure 1, a cross-sectional view of the first snap structure 4 is shown, extending along its longitudinal direction. A first locking hook 43 extends horizontally from the bottom end of the first snap structure. A first hook portion 44 is provided on the top of the first locking hook 43. The first locking hook 43 engages with the second locking groove and second locking tongue of the third engaging structure, and the shape of the first hook portion 44 matches the second locking groove.

[0042] The first engaging structure 4 also includes a horizontally opened relief step 41 and a third locking groove 42. The relief step 41 is used to clear the first locking tongue of the third engaging structure, leaving space for the first locking tongue. The relief step 41, third locking groove 42, and first locking hook 43 can be arranged in sequence from top to bottom. In other embodiments, they can also be arranged from bottom to top. A schematic diagram of the coordination between the third snap structure and the first snap structure can be seen in Figure 6.

[0043] As shown in FIG4 , a cross-sectional view of the second snap-fit ​​structure 5 is shown. The second snap-fit ​​structure 5 extends along the long side direction.

[0044] A second locking hook 53 protrudes horizontally from the middle of the second engaging structure, and a second hook portion 55 is provided at the end of the second locking hook. The second engaging structure also includes a fourth locking slot 51 with a horizontal opening and a fifth locking slot 52 with a downward opening. The fourth locking slot 51, second locking hook 53, and fifth locking slot 52 can be arranged sequentially from top to bottom. In other embodiments, they can also be arranged from bottom to top.

[0045] The second locking hook is configured to engage with the third locking groove 42 of the first locking structure 4. The fifth locking groove is configured to engage with the first locking hook 43 of the first locking structure. The shape of the fifth locking groove matches the first hook portion of the first locking hook 43. The shape of the second locking portion of the second locking hook matches the shape of the third locking groove. A schematic diagram of the first and second locking structures during horizontal installation is shown in Figure 8, and a schematic diagram after installation is shown in Figure 9. As can be seen, the panel units in this application can be connected through horizontal snap fastening, without requiring vertical snap fastening, making installation convenient and space-saving.

[0046] The side surface of the fifth locking groove 52 close to the second locking hook is an oblique side surface.

[0047] The fourth locking groove is used to engage with the first locking tongue 64 of the third engaging structure. The second locking hook can also engage with the first locking groove of the third engaging structure. Please refer to Figure 7 for a schematic diagram of the cooperation between the third buckle structure and the second buckle structure.

[0048] As shown in Figure 10, it shows the cooperation between the third snap-fit ​​structure and the second snap-fit ​​structure, and a cross-sectional view of the cooperation between the third snap-fit ​​structure and the first snap-fit ​​structure. The figure shows a schematic diagram of the connection of the three plate units in the cross section.

[0049] Please refer to Figure 11. Another aspect of this embodiment also provides a spliced ​​plate formed by alternating splicing of any of the above herringbone locking plate units. The number of spliced ​​plate units is determined by the size of the plate unit and the area of ​​the paving area. The at least four herringbone locking plate units include a first herringbone locking plate unit 11, a second herringbone locking plate unit 12, a third herringbone locking plate unit 13, and a fourth herringbone locking plate unit 14.
