A roller skating structure and speed skating shoes that are convenient for starting and accelerating

Abstract

The invention discloses a roller skating structure and speed skates which are convenient for starting and accelerating. The roller skating structure includes two installation frames parallel to each other and oppositely arranged, a pulley assembly, and a starting roller whose rotational friction force decreases as the speed increases. Acceleration assembly, auxiliary acceleration assembly, the pulley assembly is rotatably installed between two installation frames, the start acceleration assembly is installed on the pulley assembly, and the auxiliary acceleration assembly will be installed on the two installation frames, by adding The starting friction of the speed skating shoes makes the initial speed the smallest and the frictional force is the largest. As the ring roller of the speed skating shoes rotates, the centrifugal force increases, the friction force decreases, and the speed increases, so as to achieve the purpose of speed skating.

Description

technical field [0001] The invention relates to the field of speed skating shoes, in particular to a roller skating structure and a speed skating shoe which are convenient for starting acceleration. Background technique [0002] Speed ​​skates, also called speed roller skates, are a type of roller skates. It is divided into adult speed skating and children's speed skating. Most of the users of speed skating shoes are professional roller skaters, which are generally used in competitions, racing, etc. People who play speed skating are generally more professional. They will look at the quality of their shoes. Advanced speed skating shoes are generally made of glass fiber and carbon fiber, and the surface is basically microfiber leather. High elasticity, strong grip, and race wheels. The race wheels mainly focus on small ground contact area, low frictional resistance, fast starting speed, non-slip, and strong grip. [0003] The publication number is CN108014484A, and in the i...

AI Technical Summary

Problems solved by technology

[0003] The publication number is CN108014484A, and the invention named "an acceleration device for roller skates" uses the forefoot to drive the ratchet forcefully, and the ratchet and roller skates are connected by keys to realize continuous acceleration of the pulley. The disadvantages are: 1. Because the center of gravity of the person is forward, the characteristics of the ratchet stop the pulley during the speed skating process, and the speed skating effect is not ideal; 2. Emergency stop of the pulley will cause people to fall forward due to inertia, and the safety factor is small; 3. When accelerating It is necessary to forcefully drive the ratchet and the pulley to engage with the forefoot, which is inconvenient to operate
