Description

Technical Field

[0001] The utility model relates to the technical field of ice skates, in particular to an ice skate with adjustable size. Background Art

[0002] Ice skates are a common sports equipment. Traditional ice skates are usually fixed in size. However, for growing children, their feet will grow larger over time, which requires larger-sized ice skates. However, such frequent replacement of ice skates is not only costly, but may also affect children's enthusiasm and willingness to continue to participate in skating. Therefore, it is necessary to design an ice skate that can adjust the size as the size of the child's foot increases.

[0003] In order to solve the above problems, the authorization announcement number CN2619503Y discloses a size-adjustable ice skate shoe, which specifically discloses that it includes a shoe body and a heel part, the toe is connected to the front end of the sole through a sliding connection device so that it can move longitudinally relative to the sole, and a size adjustment device that can adjust and lock the longitudinal relative position of the toe and the sole is also installed between the toe and the sole. The size adjustment device includes a positioning groove, a positioning buckle and a return spring, and a row of sawtooth-like clamping teeth are provided on the outer side wall of the positioning groove, and a clamp that can be aligned and engaged with the clamping teeth is provided at the front end of the positioning buckle.

[0004] Although the above-mentioned ice skates have the function of adjusting the size, there are still some areas that need to be improved. For example, when adjusting the size of the ice skates, one hand needs to press the positioning buckle all the time, and the positioning buckle retreats against the elastic force of the return spring, so that the buckle of the positioning buckle is separated from the locking teeth on the positioning groove, and the other hand pulls the toe of the ice skates to move the ice skates forward and backward, thereby adjusting the size of the ice skates. Since the positioning buckle needs to be pressed all the time by hand during the above operation, the operation is not very convenient, and further improvements need to be made to the existing technology.
