A kind of overspeed protection device installed on the single-row roller skates

Abstract

The invention provides an overspeed protection device additionally arranged on single-row roller skates. The overspeed protection device comprises a pair of fixed support frames in symmetrical arrangement, wherein a support shaft is fixed on the front end of the two fixed support frames; a driven wheel is arranged on the support shaft through a slide wheel; a plurality of pairs of wheel brake blocks are uniformly distributed on the peripheral side of the driven wheel; all wheel brake blocks are respectively and symmetrically arranged at the two sides of the driven wheel; the wheel brake blocksare connected with the driven wheel through a leaf spring, and are arranged at one end, far away from the driven wheel, of the elastic sheet; the back ends of the fixed support frames are provided with an installing part used for being connected with a slide wheel support frame arranged at the front end of the single-row roller skates; the driven wheel is attached to a first slide wheel arrangedat the front end of the single-row roller skates; when the single-row roller skates move, the driven wheel rotates together with the slide wheel; in addition, each pair of the wheel brake blocks mutually gather under the effect of centrifugal force generated when the driven wheel rotates. A user can decelerate by using the overspeed protection device when the speed is too high in the single-row roller skates using process.

Description

technical field [0001] The invention belongs to the field of roller skates, in particular to an overspeed protection device installed on single row roller skates. Background technique [0002] Roller skating is loved by people as a kind of mainstream sports now, and at home, people generally like to use single-row roller skates to move. But when practicing with single-row roller skates, especially beginners and children who have mastered a small amount of roller skating basics. People at this time tend to speed up too much due to unintentional acceleration exercises, but due to poor grasp of the foundation and too much speed inertia, it is difficult for beginners to control, and at this time the body will lose balance and fall. And the human body will bear a lot of impact when falling, and the probability of people's injury will be greatly improved. [0003] In order to reduce injuries caused by beginners and children who cannot control the speed of roller skating under sp...
