As Figures 1-6As shown in the figure, the adjustable-size roller skates include: a shoe tip 1, a heel part 2, a shoe bottom 3, and a size adjustment device 4 connecting the shoe tip 1 and the shoe bottom 2. The size adjustment device 4 can adjust the longitudinal relative position between the shoe tip 1 and the shoe bottom 2; the size adjustment device 4 is arranged at the rear end of the shoe bottom 2 near the heel part 3, that is, the rear end of the shoe bottom 2; the size adjustment device 4 includes a sliding link 6 connected to the shoe tip 1, and a positioning sliding mechanism 5 arranged on the sliding link 6; the shoe tip 1 can move longitudinally back and forth relative to the shoe bottom 2 through the positioning sliding mechanism 5.

[0022] According to an embodiment of the present invention, the sliding link 6 is composed of a link plus a fixed flat conical part 7 and a movable flat conical part 8.

[0023] According to an embodiment of the present invention, the fixed flat conical part 7 has a shape that is narrow at the top and wide at the bottom, and the movable flat conical part 8 has a shape that is wide at the top and narrow at the bottom.

[0024] According to an embodiment of the present invention, two sets of symmetric chute block screws 11, slider parts 9, and a strip groove 10 for accommodating the slider parts 9 are further provided at the rear end of the positioning sliding mechanism 5; the slider parts 9 are sleeved on the chute block screws 11 and can slide horizontally on the chute block screws 11; the slider parts 9 are composed of rotatable rib positioning chute blocks 13 suitable for moving in the strip groove 10 and a return spring 12.

[0025] Specifically, when it is necessary to adjust the length of the roller skates, the rotatable rib positioning chute blocks 13 on both sides can be pulled backward along the strip groove (10). After adjusting the positioning sliding mechanism 5 to make the shoes the required size, the slider parts 9 are placed between the fixed flat conical part 7 and the movable flat conical part 8 (as Figure 5 ), and then the rotatable rib positioning chute blocks 13 are released. The slider parts 9 are positioned by the return spring 12 from the strip groove 10 between the fixed flat conical part (narrow at the top and wide at the bottom) 7 and the movable flat conical part (wide at the top and narrow at the bottom) 8, achieving a buckling effect, thereby realizing the adjustment of the size of the roller skates.

[0026] It should be noted that there is a gap between the fixed flat conical part 7 and the movable flat conical part 8, as Figure 6 shown, and the width of this gap is slightly larger than the width of the slider parts 9. The movable flat conical part 8 can be made of a high shock-absorbing material.

[0027] It should also be noted that the slider part 9 can be designed as a wedge shape and can cooperate with the fixed flat conical part 7 with a narrow upper part and a wide lower part. In addition to being able to be stuck in the gap between the fixed flat conical part 7 and the movable flat conical part 8, the slider part 9 can also be stuck at the fixed flat conical part 7 with a narrow upper part and a wide lower part. Correspondingly, the shape of the movable flat conical part 8 is opposite, with a wide upper part and a narrow lower part, for the purpose of being easy to identify and preventing misoperation. As Figures 4-6 shown, since the slider part 9 is sleeved on the chute block screw 11, the slider part 9 can rotate. When it is necessary to be stuck at the fixed flat conical part 7, it is necessary to pay attention to rotating the slider part 9 to an appropriate position. In the embodiment provided in this application, it is rotated by 90 degrees.

[0028] For the adjustable-size roller skates according to the present invention, a size adjustment device is provided at the sole and the rear end of the shoe head, so that the connection between the shoe body and the shoe head is more firm. Through this telescopic adjustment device with a special structure, there is no need to repeatedly lock the connecting piece with great effort, and the size adjustment can be easily realized. By adopting the movable flat conical part design of high shock-absorbing material, the parts of the adjustable-size device have buffering ability, reduce the loss of parts, and improve sports safety.

[0029] The above embodiments are the preferred implementation solutions of this application. In addition, this application can also be implemented in other ways. Any obvious replacement without departing from the concept of this application is within the protection scope of this application.
