Description
Technical Field
The invention belongs to the field of roller skates, and particularly relates to an overspeed protection device additionally arranged on a single-row roller skate.
Background
Roller skating is popular among people as a mainstream sports, and is popular among people in China. But especially beginners and children who have mastered a small number of roller skating bases when practicing with the roller skates in a single row. People often have too high speed due to inadvertent acceleration exercise, but the basic control is not firm and the speed inertia is too large, so that the beginners can hardly control the exercise, and the body can lose balance and fall. The human body can bear large impact force when falling down, and the probability of injury of people is greatly improved.
In order to reduce the damage event caused by incapability of controlling the skidding speed of beginners and children under special conditions, the speed limiting device designed by the invention can be additionally arranged on common single-row skidding shoes, when the skidding speed is too high, the device is driven to rotate and generate centrifugal force, and the centrifugal force is used for driving the wheel brake to limit the rolling speed of the wheel. Thereby increasing the ability of people to control speed and reducing injuries caused by roller skating.

Detailed Description
The technical scheme of the invention is further explained in detail by combining the attached drawings:
an overspeed protection device additionally installed on a roller skate 1 is installed at the front end of the roller skate 1 as shown in figures 1 and 2, and the roller skate 1 is provided with a wheel 2, a wheel 3, a wheel 4, a wheel 5 and a wheel 6 5 of a wheel 1 through a pulley bracket 7 and a fixing screw 8. The invention comprises a pair of fixed brackets 9 which are symmetrically arranged, wherein the front ends of the two fixed brackets 9 are fixedly provided with a supporting shaft 12, the supporting shaft 12 is provided with a driven wheel 16 through a pulley, a plurality of pairs of wheel brake blocks 11 are uniformly distributed on the periphery of the driven wheel 16, each pair of wheel brake blocks 11 are respectively and symmetrically arranged on two sides of the driven wheel 16, the wheel brake blocks 11 are connected with the driven wheel 16 through spring leaves 15, and one ends of the spring leaves far away from the driven wheel 16 are arranged; the wheel brake block 11 is further provided with a balancing weight 10, and the wheel brake block 11 and the balancing weight 10 are fixed on the spring piece 15 through fastening screws 14. The rear end of fixed bolster 9 is provided with the installation department that is used for being connected with the pulley support 7 of roller skate 1 front end, installation department and fixed bolster 9 are 120 degrees contained angles. The mounting portion is provided with a distance adjusting groove 17. The driven wheel 16 is attached to a first pulley at the front end of the roller skate 1; when the skate 1 is in motion, the driven wheels 16 rotate together with the sheaves, and each pair of the wheel brake blocks 11 are gathered each other by a centrifugal force generated when the driven wheels 16 rotate.
Description of specific embodiments:
before movement, the mounting parts are mounted on the two pulley supports 7 where the No. 4 wheel 5 and the No. 5 wheel 6 of the roller skate 1 are located through the distance adjusting grooves 17, and meanwhile, the distance between the roller skate and the No. 5 wheel 6 is adjusted through the distance adjusting grooves 17, so that the driven wheels 16 and the No. 5 wheel 6 are attached, namely the No. 5 wheel 6 rotates, and the driven wheels 16 also rotate along with the roller skate.
After the installation is completed, when the user wears the roller skate 1 to exercise, each pair of the brake blocks 11 are gathered together by the centrifugal force generated when the driven wheel 16 rotates. Under the condition that the speed of the roller skate 1 is normal, the centrifugal force generated by the driven wheel 16 is small, the deformation amount of the spring piece 15 is small, the mutual gathering degree of each pair of the wheel brake blocks 11 is small, and the wheel brake blocks 11 cannot contact with the No. 5 wheel 6. However, when the speed of the roller skate 1 exceeds the normal speed, the wheel brake blocks 11 gather together under the action of strong centrifugal force, the deformation of the spring piece 15 is increased, the wheel brake blocks 11 can continuously contact the 5 th wheel 6, so that the friction force of the 5 th wheel 6 is increased, the 5 th wheel 6 is decelerated, and finally the roller skate 1 is decelerated. Until the speed of the roller skate 1 returns to normal, the centrifugal force of the driven wheel 16 is reduced and is not enough to enable the spring piece 15 to generate large deformation, so that the wheel brake block 11 is separated from the No. 5 wheel 6 again, and the roller skate 1 returns to normal. Therefore, after the device is arranged on the roller skate 1, the increased speed is reduced by the device when the speed is overlarge, so that people can be ensured not to lose balance and fall down due to sudden acceleration of the roller skate 1 during movement, and the movement dangerousness of beginners and children is reduced.
The distance adjusting groove can adapt to roller skates with different sizes or different wheel diameters, and the adaptation range is wide.
