Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of roller skates, more specifically to a roller skate with stable structure and convenient operation. BACKGROUND

[0002] In recent years, there have been roller skates with folding function on the market. When not sliding, the wheels are folded into the inner side of the sole, so that the roller skate can be switched to a sports shoe and can walk normally. Most of the roller skates on the market have a relatively complex structure, and it is relatively cumbersome to jump out and store the wheels. It is not convenient to use, especially for small children. Some roller skates require a certain amount of strength to pull out and fold the wheels, and there may be a lack of strength. In addition, some roller skates have many parts, which may fall off or break during sliding, increasing the risk of safety. The above has become a concern for many users and parents. To solve this problem, the present inventor proposes a roller skate with stable structure and convenient operation. The front and rear parts of the roller skate are respectively provided with a wheel structure. The wheel structure is stable and easy to operate, and can be conveniently jumped out and stored, effectively improving the safety of the roller skate.

[0003] In order to improve the multifunctionality of the roller skate, the roller skate can be quickly switched between the roller skate and the sports shoe, achieving the effect of convenient use. Chinese patent (grant announcement number: CN217661425U) discloses a shoe with folding wheels. The utility model includes: a sports shoe body, the bottom surface of the sports shoe body is fixedly connected with an elastic pad, the bottom surface of the elastic pad is fixedly connected with a sole plate, the bottom surface of the sole plate is provided with symmetric positioning grooves, the inner side walls of the two positioning grooves are respectively provided with symmetric first fixing grooves, the inner part of each group of first fixing grooves is fixedly connected with a first fixing block, and the side face of each group of first fixing blocks is hinged with a first fixing shaft through a first pin shaft. The utility model utilizes the first fixing shaft to expand the support column, and utilizes the second fixing shaft to expand the wheel, so that each wheel is in contact with the bottom surface. The sports shoe body can slide, saving people's strength. The shoe can become a roller skate when needed, achieving the purpose of fast walking.

[0004] This scheme still has some deficiencies in application. When the roller skate is switched, it needs to be fast and convenient, otherwise it will be inconvenient to switch, resulting in poor experience. In addition, the roller skate needs to have a good stable structure after switching to avoid the risk of parts falling off or breaking during sliding. Therefore, the support structure of the wheel needs to be stable and durable. Therefore, the structure of the roller skate needs to be improved so that it not only has a good stable structure, is durable and convenient to switch, and has a wide range of applications.
