These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0024] Reference Figure 1 and Figure 2 As shown, this application discloses a card strip assembly 100, which includes a female snap-on card strip 10 and a male snap-on card strip 20 that are snapped together.

[0025] The female buckle strip 10 is made of PP or ABS plastic by injection molding or extrusion molding. In this way, the female buckle strip 10 can be mass-produced through molds, which is efficient and the product consistency is also high.

[0026] Please refer to the reference again. Figures 3-4 As shown, the female buckle strip 10 includes a female buckle strip body 11, and a hook part 12, an installation part 13, an overlap part 14, a positioning part 15, a splicing part 16, and a reinforcing rib 17 fixed on the female buckle strip body 11. In this embodiment, the female buckle strip body 11 is a square plate structure.

[0027] Along the length of the female fastener body 11, the hooking part 12 protrudes upward from one long side of the female fastener body 11 and is located in the middle of the female fastener body 11. The length of the hooking part 12 is less than the length of the female fastener body 11.

[0028] Along the length of the female buckle body 11, the mounting part 13 and the hooking part 12 are arranged opposite to each other and extend upward from the other long side of the female buckle body 11. To prevent the mounting part 13 from coming off under force, in this embodiment, the end of the mounting part 13 away from the female buckle body 11 is also provided with an outwardly bent overlapping part 14. It should be noted that "outer" here refers to the side away from the female buckle 10.

[0029] In one embodiment, multiple overlapping portions 14 are provided, spaced apart along the length of the female fastener body 11, and the spacing between the multiple overlapping portions 14 remains consistent. This spacing can be adjusted according to the installation position, etc., and is not specifically limited here.

[0030] In addition, fixing holes can be pre-drilled on the overlapping part 14. These fixing holes can be round, square, or rectangular. The advantage of using rectangular holes is that they allow for fine-tuning during installation to compensate for dimensional tolerances between the frame 200 and the female fastener strip 10.

[0031] The positioning part 15 extends upward from the top of the female buckle body 11 and is located on both sides of the hook-on part 12. This restricts the lateral sliding of the components fixed to the hook-on part 12. When the male buckle 20 is inserted into the hook-on part 12 from top to bottom, to prevent collision between the positioning part 15 and the male buckle 20, and to facilitate quick installation between the male buckle 20 and the female buckle 10, the positioning part 15 has a guide surface on the side near the hook-on part 12, which is inclined downwards. Thus, the space between the two positioning parts 15 forms a guide groove. When the male buckle 20 is inserted, it first contacts this guide groove and is automatically corrected to the correct engagement position, realizing the "guide first, then engage" installation logic, effectively avoiding forced insertion and component damage due to misalignment.

[0032] The splicing portion 16 extends upward from the top of the female buckle strip body 11 and connects the overlapping portion 14 and the positioning portion 15 respectively. In this way, the two parts are connected together by the splicing portion 16, making the entire female buckle strip 10 a rigid whole. This avoids the overlapping portion 14 or the positioning portion 15 from undergoing separate and uncontrollable deformation under stress.

[0033] In one embodiment, the connection between the splicing part 16 and the overlapping part 14 and the positioning part 15 is arc-shaped, which effectively eliminates stress concentration, enhances the overall structural strength of the female buckle strip 10, and extends its service life.

[0034] Multiple reinforcing ribs 17 are provided, and their distribution pattern can be optimized into a grid or radial pattern. Grid-shaped reinforcing ribs 17 provide uniform rigid support, while radial reinforcing ribs 17 focus more on efficiently transferring the force borne by the hook portion 12 to the edge of the female buckle body 11 and the mounting portion 13. The height of the reinforcing rib 17 is 1 to 3 times its base width; this height-to-width ratio ensures the reinforcement effect while avoiding aesthetic defects caused by excessive rib thickness.

[0035] The male buckle strip 20 is made of PP or ABS plastic by injection molding or extrusion molding. In this way, the male buckle strip 20 can be mass-produced through molds, which is efficient and the product consistency is also high.

[0036] Please refer to the reference again. Figure 4 As shown, the male buckle strip 20 includes a male buckle strip body 21, a hook structure 22 and a connecting part 23 fixed on the male buckle strip body 21.

[0037] The hook structure 22 extends upward from the top of the male buckle strip body 21, then bends towards the top side of the hook part 12, and finally bends towards the bottom of the hook part 12, forming an approximately C-shaped hook structure 22.

[0038] In one embodiment, the inner surface of the C-shaped hook structure 22 is adapted to the outer contour of the hook portion 12. To further improve the firmness and feel of the hook, the inner side of the hook structure 22 may be provided with raised elastic locking points or friction stripes.

[0039] When the male snap-fit ​​strip 20 engages with the female snap-fit ​​strip 10, the elastic locking point will pass over the highest point of the hook-on part 12 and embed itself, producing a distinct "click" sound and tactile feedback, providing the installer with a clear signal that the installation is in place. The friction stripes increase static friction and prevent loosening under vibration.

[0040] The connecting portion 23 is a square plate-shaped structure. The connecting portion 23 extends horizontally outward from the bottom of the male buckle body 21 and is parallel to the bottom of the wooden buckle body. In another embodiment, the connecting portion 23 extends obliquely downward from the bottom of the male buckle body 21.

[0041] Reference Figure 1 As shown, this application also discloses a seating fixture, which includes a frame 200, a soft padding, and a buckle assembly 100. The female buckle 10 is fixed to the frame 200 via an overlap portion 14, and the soft padding is connected to the connecting portion 23 of the male buckle 20.

[0042] In one embodiment, the overlapping portion 14 is bonded to or secured to the frame 200 with screws. The soft padding and the male buckle strip 20 are secured by sewing or bonding.

[0043] Furthermore, when the connecting portion 23 of the male buckle strip 20 is used to fix the soft pack, its surface can be designed with multiple anchoring holes or barbed structures. When fixed by sewing, the thread can pass through the anchoring holes. When fixed by bonding or embedding foaming processes, the barbed structures can be deeply embedded in the soft pack material, forming an extremely strong mechanical interlock to prevent the edges of the soft pack from lifting or peeling off.

[0044] This snap-lock assembly 100 is particularly suitable for seating furniture that requires frequent upholstery replacement or cleaning, such as car seats, office chairs, and sofas. The installation method is as follows: First, secure the female snap-lock 10 to the seat frame 200 via its overlapping portion 14; then, pre-fix the male snap-lock 20 to the edge of the upholstery; finally, simply align the hook structure 22 of the male snap-lock 20 with the hook portion 12 of the female snap-lock 10 and press down until you hear or feel the engagement. For disassembly, simply lift the edge of the upholstery upwards to disengage the hook structure 22 from the hook portion 12. The entire process is tool-free and quick. This design greatly improves the maintenance efficiency and modular design level of the seating upholstery.

[0045] This application utilizes the interaction between the hook part 12 of the female snap-on strip 10 and the hook structure 22 of the male snap-on strip 20 to enable the strip assembly 100 to be easily and quickly aligned and snapped together in the length direction, simplifying the assembly process, improving installation efficiency, and effectively preventing the soft package from becoming loose or shifting.
