Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of roller skate shoes, more specifically to a roller skate shoes' s wheel lifting structure. BACKGROUND

[0002] The roller skate shoes are unique sports shoes with one or more wheels on the soles, and the wearer can wheel on the ground in a few steps. The roller skate shoes can be used to make various sliding actions to reflect street culture, and the wheels can be hidden to become very comfortable leisure shoes. The roller skate shoes can be walked and rolled, and are popular among young people. The existing roller skate shoes are divided into two types, one with two wheels and the other with four wheels. The difference between the two types is that the former has an additional set of wheels on the forefoot, which is more convenient for sliding. At present, there are many roller skate shoes with two wheels on the market that can be lifted quickly. However, there is no design for the lifting of the wheel set of the roller skate shoes with four wheels. When switching, the user needs to hide the front and rear wheel sets separately, which is time-consuming and laborious, inconvenient to operate, and needs to be improved in structure. In view of this, the present inventors propose a roller skate shoes' s wheel lifting structure to solve this problem. Through the lifting structure, the front and rear wheels can be protruded and hidden simultaneously quickly. The structure is simple, convenient to operate, and more in line with the needs of young people.

[0003] In order to realize the switching between the roller skate shoes and the leisure shoes and meet the fashion needs of young people, a roller skate shoe with size adjustment is disclosed in Chinese patent application No. CN221732331U. The utility model sets a horizontal moving shoe cavity lining in the shoe cavity. The shoe cavity lining moves horizontally under the action of the screw rod rotating structure. The screw rod structure is embedded in the sole. Without increasing the height of the shoes, by rotating the twist locking wrench left or right which is set outside the shoes, the screw rod and the shoe cavity lining are moved horizontally, thereby driving the semi-closed toe to move left and right in the shoe body, realizing the effect of adjusting the size, prolonging the use time of the shoes, and saving additional expenses.

[0004] The scheme still has some deficiencies in application. Since the roller skate shoes need to be switched between the roller skate shoes and the leisure shoes, when used as leisure shoes, the front and rear wheels need to be hidden. The hiding should be as convenient as possible, preferably without taking off the shoes. Otherwise, it is not convenient to switch, resulting in poor comfort. Moreover, it is better to hide the front and rear wheels simultaneously to simplify the wheel hiding steps and further improve the switching efficiency, so that the wearing experience is better. Therefore, the wheel structure of the roller skate shoes needs to be improved to make the structure simpler and more convenient for switching, which is more in line with the usage of young people and improves the practicality.
