[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See attached Figure 1-3 This embodiment provides a fastening and assembly structure for a detachable ice skate blade core, including an ice skate base 1, a blade core 2, a stop nut 3, and a locking screw 4 used in conjunction with the stop nut 3;

[0029] The outer sides of the blade core positioning hole on the skate base 1 are provided with concave steps 11 adapted to the anti-rotation nut 3, and a through hole I 12 adapted to the anti-rotation portion of the anti-rotation nut 3;

[0030] The blade core 2 is also provided with a through hole II 21 adapted to the anti-rotation portion of the anti-rotation nut 3;

[0031] The anti-rotation nut 3 includes a nut head 31 , an anti-rotation boss 32 , and an internal threaded hole 33 passing through the anti-rotation nut 3 .

[0032] The recessed step 11 is adapted to fit the nut head 31 .

[0033] The through hole I12 and the through hole II21 are matched with the anti-rotation boss 32 .

[0034] The blade core 2 is embedded in the bottom groove 13 of the skate base 1 .

[0035] See also Figure 4-9 The anti-rotation boss 32 includes a variety of geometric shapes and structures. The anti-rotation boss 32 on the anti-rotation nut 3 can be designed as a triangle, square, pentagon, hexagon, petal, elliptical and other structures.

[0036] The locking screw 4 includes a screw head and an externally threaded rod. The externally threaded rod is adapted to the internally threaded hole 33 of the anti-rotation nut 3 and the two are threadedly connected.

[0037] During assembly, the blade core 2 is embedded in the bottom groove 13 of the ice skate base 1, and is locked by threaded connection with the stop nut 3 and the locking screw 4. The stop boss 32 on the stop nut 3 fits through the corresponding through hole Ⅱ 21 of the same shape of the blade core 2, and the stop nut 3 achieves the anti-rotation effect. Then use a wrench to tighten the locking screw 4 to clamp the blade core 2 in the bottom groove 13 of the ice skate base 1. Compared with traditional locking screws and nuts, which require additional tools to stop the nut from rotating, the assembly process of this anti-rotation nut structure is more optimized and can reduce industrial costs.
