Document Type and Number:
WIPO Patent Application WO/2018/120540
Kind Code:
A1
Abstract:
A high-strength tension-resistant stud comprises a snap button base (1) comprising a snap button(2) arranged at a lower end of the snap button base (1). An alloy insertion piece (3) is arranged at a lower end of the snap button (2). Alloy insertion piece feet (4) are arranged at a lower end of the alloy insertion piece (3). A prong rubber ring (5) is arranged inside the alloy insertion piece (3), and comprises prong support legs (6) arranged at an upper end of the prong rubber ring (5). A ring holder (8) is arranged below the alloy insertion piece (3). A ring holder fixing edge (9) is arranged at an upper end of the ring holder (8). An elastic cup (10) is arranged at a lower end of the prong rubber ring (5). The alloy insertion piece (3) is connected to the ring holder fixing edge (9) via the alloy insertion piece legs (4). The embodiment is simple in structure and novel in design. Specifically, the prong rubber ring is formed by performing die-casting on a nylon material, adopts an eight-pit principle, and fully utilizes elasticity of the nylon to produce an expanding force, requiring less costs than a metal elastic ring, and having a favorable promotion value.
