Description

Technical Field

[0001] The utility model belongs to the technical field of roller skates, in particular to a pair of roller skates that can be switched between single and double rows. Background Art

[0002] Roller skates, commonly known as roller skates, are a competition item that uses special roller skates as a competition tool, and are also a kind of leisure gadget. Today, most skaters mainly use inline skates. Currently, roller skates generally have two roller structures, one is a single-row roller and the other is a double-row roller. The roller design at the bottom of existing roller skates is generally single-row or double-row, and it is impossible to switch from single-row rollers to double-row rollers by adjusting the rollers. After searching, the patent with application number 202322143751.6 discloses a single-row and double-row switchable roller skates, including roller skates, the bottom of the roller skates is fixedly installed with a sole, the sole is a metal plate structure, the bottom of the sole is fixedly installed with a roller skating assembly, the roller skating assembly includes a roller frame, the inner walls on both sides of the roller frame are rotatably connected to the forward and reverse lead screws through bearings, the outer walls at both ends of the forward and reverse lead screws are threadedly connected to the threaded sleeve, the outer wall of the threaded sleeve is rotatably connected to the roller through a bearing, and the two rollers are controlled by the forward and reverse lead screws to move towards and in reverse directions.

[0003] However, in actual use, the applicant found that by controlling the two rows of rollers to approach each other and merge, it can switch to single-row roller skates, and by controlling the two rows of rollers to move away from each other and separate, it can switch to double-row roller skates. This switching method makes the wheel body of the single-row roller skate wider, thereby reducing the experience of single-row roller skating. In view of this, we propose a pair of roller skates that can switch between single and double rows. Utility Model Content
