AI Technical Summary
Existing interlocking flooring lacks sufficient horizontal and vertical restraints, making it prone to loosening and misalignment due to external forces or its own deformation. Furthermore, changes in ambient temperature cause the flooring to expand and contract, leading to compression, stretching, or even cracking.
The tenon and mortise mechanism, combined with the vertical positioning components of the slot and hook, incorporates a flexible component to provide room for deformation. The horizontal limiting component and the vertical positioning component ensure stability in both directions, preventing loosening and misalignment.
It improves the stability and safety of interlocking flooring, prevents loosening and misalignment caused by external forces or its own deformation, reduces the impact of thermal expansion and contraction, and ensures the stability and safety of the flooring.

[0035] Specifically, the first assembling belt 1 and the second assembling belt 2 have the same main structure, preferably a strip-shaped belt is adopted, and the cross section of the strip-shaped belt can be rectangular or square. Horizontal limiting assembly and vertical positioning assembly are arranged on one side of the strip-shaped belt. In the utility model, horizontal limiting assembly and vertical positioning assembly are arranged adjacent to each other, and multiple are equidistantly arranged on the side.
[0036] Among them, in horizontal limiting assembly, tenon 31 can be selected in multiple shapes, such as column head, semicircle or tongue and groove, etc. In the embodiment, dovetail tenon is adopted, which not only has beautiful appearance, and the shape of tenon 31 with narrow root and wide end is similar to ladder stand, so that tenon 31 and mortise 32 realize high-strength joint at corner part, and effectively avoid the disconnection of object under stress.
[0037] In vertical positioning assembly, clamping hook 42 includes hook body 421 connected to the outer side of the first assembling belt 1 or the second assembling belt 2 and hook head 422 outwardly extended at the end of hook body 421. Auxiliary inclined surface 423 is arranged on the outer side of hook head 422, and the angle of auxiliary inclined surface 423 is greater than or equal to 30 degrees and less than or equal to 60 degrees, so as to facilitate the determination of deformation direction during disassembly. Preferably, hook body 421 is outwardly extended on the side, which can produce certain deformation, and auxiliary inclined surface 423 is arranged to facilitate the understanding of the deformation direction of clamping hook 42, facilitating disassembly. During assembly, hook head 422 is vertically pressed down to hook clamping groove 41, and vertical fixation is completed.
[0038] In the embodiment, referring to Figure 1 and Figure 3, the tenon 31 is vertically outwardly arranged on the first assembling belt 1, and the mortise 32 is downwardly and inwardly arranged on the second assembling belt 2; the clamping groove 41 is downwardly and inwardly arranged on the first assembling belt 1, and the clamping hook 42 is vertically outwardly arranged on the second assembling belt 2. As shown in the figure, the side of the first assembling belt 1 on the right side of the tenon 31 is downwardly provided with the clamping groove 41; correspondingly, the clamping hook 42 is arranged on the left side of the mortise 32 on the side of the second assembling belt 2 matched with the first assembling belt 1.
[0039] It should be noted that, in the utility model, the mortise and tenon cooperation and the clamping assembly both need to have a deformation gap, so that a recessed part is arranged on the side wall of the mortise 32 and the side of the clamping hook 42, a buffer space is left, the disassembly and assembly are facilitated, and meanwhile the influence caused by the expansion and contraction of the material due to the environmental influence and the influence caused by the loosening or extrusion deformation of the sports floor due to the expansion and contraction can be offset.
[0040] Further, the splicing structure further comprises an elastic member 5, the elastic member 5 is located in the recessed part, that is, the elastic member 5 is adjacently arranged on the side of the mortise 32 and located on the back side of the clamping hook 42. Therefore, the elastic member 5 can not only save space, but also provide a deformation space and support and fixation for the horizontal limiting assembly and the vertical positioning assembly. Preferably, the elastic member 5 is integrally connected with the side wall of the mortise 32, so that the stability is enhanced. As shown in the figure, the elastic member 5 comprises an auxiliary wall 51 and a reinforcing rib 52 in T-shaped distribution, wherein the auxiliary wall 51 adjacent to the mortise 32 can directly serve as the side wall of the mortise 32; the reinforcing rib 52 is vertically arranged on the outer side of the auxiliary wall 51 and effectively prevents the auxiliary wall 51 from being excessively deformed. In addition, the reinforcing rib 52 can also abut against the side edge of the hook body 421 of the clamping hook 42, so as to improve the stability of the clamping hook 42. Figure 3
[0041] When the first assembling belt 1 and the second assembling belt 2 of the splicing structure of the utility model are assembled, the clamping hook 42 is clamped into the clamping groove 41 or deformed under external force, the hook body 421 is deformed into the recessed part under stress, the reinforcing rib 52 is extruded, so that the auxiliary wall 51 clamps the tenon 31, and the connection of the horizontal limiting assembly is more stable. Conversely, when the tenon 31 is pulled by external force, the reinforcing rib 52 is extruded by the auxiliary wall 51, the clamping hook 42 is close to the clamping groove 41, and the connection of the vertical positioning assembly is more compact. Therefore, the splicing structure of the utility model has the advantages of strong anti-deformation ability and high stability through the cooperation of the horizontal limiting assembly and the vertical positioning assembly.
