Description

Technical Field

[0001] This utility model relates to the field of flooring technology, specifically to a double-curved arc-connected snap-lock floor. Background Technology

[0002] Solid wood flooring is widely loved by customers for its superior texture and grain, while composite flooring is also favored by customers for its stability and variety. At the same time, home decoration is no longer satisfied with rectangular splicing. Various herringbone and chevron patterns have been invented in the market, which requires the board connection structure to be diversified, no longer similar to the usual concave-convex connection.

[0003] To enable herringbone and chevron flooring patterns, adjustments need to be made to the connection structure and installation method. Unlike the standard interlocking joints where the boards are joined side by side, most existing flooring is made of straight strips with right-angled corners, making it less aesthetically pleasing. Furthermore, it is not as easy to join as curved flooring, and when vertically joining boards, there is no corresponding limiting groove structure at the joint, which cannot guarantee its stability. Utility Model Content

[0004] The purpose of this invention is to provide a double-curved arc-connected snap-fit ​​floor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-curved arc-connected snap-fit ​​floor, comprising: a rounded rectangular mortise floor and a reverse mortise floor.

[0006] One side of the positive mortise floor has a positive mortise groove for positioning, and one side of the negative mortise floor has a negative mortise groove for positioning.

[0007] Both the mortise and tenon floorboards have raised connecting parts on the side near the mortise groove and the reverse mortise and tenon floorboards on the side away from the reverse mortise groove. Both the mortise and tenon floorboards have groove connecting parts on the side away from the raised connecting parts. When the floorboards are spliced, the raised connecting parts are locked in the groove connecting parts for interlocking between the mortise and tenon floorboards.

[0008] Preferably, the mortise and tenon joints are the same size and shape, and the mortise and tenon arc grooves are arc-shaped grooves with the same radius and center.

[0009] Preferably, both ends of the positive mortise and the negative mortise are arc-shaped structures, and the radius of the arc-shaped structure is the same as the center of the circle, and the radius of the arc groove is the same as the center of the circle.

[0010] Preferably, the protruding connecting part includes a main limiting rod and secondary limiting rods symmetrically arranged on both sides of the main limiting rod.

[0011] Preferably, the main limiting rod and the secondary limiting rod have a T-shaped cross-section, and the ends of the T-shaped structure are circular.

[0012] Preferably, the groove connection includes a main limiting groove that cooperates with the main limiting rod and a secondary limiting groove that cooperates with the secondary limiting rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: the floor joint with arc grooves on the side enhances the aesthetics of the floor. Simultaneously, this type of splicing joint effectively protects against compression and pulling between floorboards, making it easier to achieve herringbone, chevron, and rectangular patterns. The double-arc shape differs from existing click-lock and flat-lock flooring; its unique irregular protruding edge better integrates with the short arc side of the floorboard. Splicing arc-shaped floorboards is easier, the structural design is more rational, the stress distribution is more even, production and processing are easier, and production efficiency is higher. The flat-locking effect on the long side makes the connection between the front and back of the floorboards more secure, and the connection methods on the short side are more diverse. The double arc effect effectively inhibits the shrinkage and expansion of the floorboards, making the floorboards more stable. The splicing connection method results in more stable flooring, allows for more diverse patterns, and produces more aesthetically pleasing splicing effects. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a double-curved arc-connected snap-fit ​​floor, comprising: a rounded rectangular mortise floor 1 and a reverse mortise floor 2. The mortise floor 1 has two mortise arc grooves 3 for positioning on one side, and the reverse mortise floor 2 has two reverse mortise arc grooves 10 for positioning on one side. The mortise floor 1 near the mortise arc grooves 3 and the reverse mortise floor 2 away from the reverse mortise arc grooves 10 are both provided with protruding connecting portions 4. The mortise floor 1 and the reverse mortise floor 2 away from the protruding connecting portions 4 are both provided with recessed connecting portions 5. When the floor is spliced, the protruding connecting portions 4 are engaged within the recessed connecting portions 5 for interlocking the mortise floor 1 and the reverse mortise floor 2.

[0023] It should be noted that both the mortise and tenon floorboard 1 and the reverse mortise and tenon floorboard 2 of this utility model are rectangular with semi-circular structures at both ends. Both the mortise and tenon floorboard 1 and the reverse mortise and tenon floorboard 2 are made of white oak, with a long side dimension of 600mm, a width of 60mm, and a thickness of 18mm. The mortise and tenon groove 3 and the raised connecting part 4 of the mortise and tenon floorboard 1 are located on the same side, and the raised connecting part 4 and the reverse mortise and tenon groove 10 of the reverse mortise and tenon floorboard 2 are located on opposite sides. The mortise and tenon floorboards are spliced ​​together in the width direction in the order of splicing the width first and then the length from top to bottom. When splicing, the raised connecting part 4 of the reverse mortise and tenon floorboard 2 is slid into the groove connecting part 5 of the mortise and tenon floorboard 1 from one end, so as to splice the mortise and tenon floorboard 1 and the reverse mortise and tenon floorboard 2 into a splicing group. The splicing group is spliced ​​parallel to each other, so that the reverse mortise and tenon groove 10 faces outward. Then, one splicing group is spliced ​​perpendicularly to another splicing group, and the end of the splicing group is inserted into the mortise and tenon groove 3. The splicing method is similar to the herringbone splicing method.

[0024] like Figure 1 , 2 As shown in Figures 5 and 6, the mortise and tenon joint 1 and the reverse mortise and tenon joint 2 are the same size and shape. The mortise and tenon arc groove 3 and the reverse mortise and tenon arc groove 10 are arc grooves with the same radius and center. Both ends of the mortise and tenon joint 1 and the two ends of the reverse mortise and tenon joint 2 are arc structures. The radius and center of the arc structure and the radius and center of the arc groove are the same.

[0025] It should be noted that, when splicing, after the mortise and tenon floor 1 and the reverse mortise and tenon floor 2 are spliced, the end of the assembly can be combined with the corresponding mortise and tenon groove 3 or reverse mortise and tenon groove 10. The connection between the mortise and tenon groove 3 and the reverse mortise and tenon groove 10 can serve to beautify the floor. The arc groove can effectively inhibit the drying shrinkage and expansion of the floor, making the floor more stable. At the same time, the use of this type of splicing connection can effectively protect the floor from compression and pulling, and make it easier to achieve herringbone, herringbone and rectangular splices.

[0026] Figure 3 , 4 As shown in Figure 5, the protruding connecting part 4 includes a main limiting rod 8 and secondary limiting rods 9 symmetrically arranged on both sides of the main limiting rod 8. The cross-section of the main limiting rod 8 and the secondary limiting rods 9 is a T-shaped structure, and the ends of the T-shaped structure are circular. The groove connecting part 5 includes a main limiting groove 6 that cooperates with the main limiting rod 8 and a secondary limiting groove 7 that cooperates with the secondary limiting rods 9.

[0027] It should be noted that when splicing this utility model, the main limiting rod 8 is inserted into the corresponding main limiting groove 6, and the secondary limiting rod 9 is inserted into the corresponding secondary limiting groove 7, so that the straight edges of the mortise floor 1 and the reverse mortise floor 2 are connected and spliced. The flat snap action can make the connection between the front and back of the floor more secure.
