Technical Field
The invention relates to the technical field of slide plate balance, in particular to a caster wheel mechanism of an anti-toppling slide plate.
Background
Skateboard exercise is a nasal ancestor of the history of extreme exercise, and many extreme exercise items are extended from skateboard items. The skateboard sports evolved from surfing in the late 50 s and early 60 s have become popular sports nowadays and are well-pursued and favored by young people.
As a beginner, the skateboard exercise has great operation difficulty, and the mastering of the balance degree is the primary difficulty. Traditional skateboard truckle adopts fixed perpendicular mounting structure's mounting means more, and is similar with common tire, but the truckle that adopts this kind of mode to install has great control degree of difficulty to the skateboard beginner: firstly, in the stress process of the traditional caster wheel, particularly when the stress is uneven, the caster wheel can drive the sliding plate to incline integrally, and a person standing on the sliding plate is more difficult to grasp the balance in the horizontal direction, so that the unbalance of a human body is easily caused by the inclination of the sliding plate; second, when the user need control the slide and turn to, then need carry out the weight bias to a certain side of slide and press to force the truckle to incline, but traditional slide and truckle be fixed body structure, and the change that realizes the direction through the truckle slope needs longer reaction cycle, especially when less space and corner, very easily causes the corner collision accident.
