The present invention discloses a centrifugal self-locking trundle which comprises a trundle seat, a trundle body is installed on the trundle seat, a plurality of arc-shaped grooves are evenly distributed in the trundle body along the center circumference of the trundle body, arc-shaped rods are arranged below the arc-shaped grooves in a bilateral symmetry mode, limiting ends are arranged at the ends of the two arc-shaped rods, sliding blocks are movably arranged in the arc-shaped rods, a centrifugal ball is movably arranged in the arc-shaped groove, a limiting plate is arranged on the sliding block, the arc-shaped rod is sleeved with a spring body used for pressing the limiting plate in the direction of the centrifugal ball, and when the transportation equipment stops moving, friction is automatically generated between the trundle and the trundle base, the trundle is automatically locked, the situation that the trundle automatically moves due to the influence of a slope or part of external force is prevented, the situation that the moved transportation equipment rolls over or topples over is prevented, the property and life safety is guaranteed, after the transportation equipment is forcibly pushed, the friction plates on the trundle are gradually disengaged, friction force is slowly reduced, and after moving, the caster is gradually in a normal rotating state, and the design is reasonable and humanized.

    本发明公开一种离心式自锁脚轮,包括轮座,所述轮座上安装有轮体,所述轮体内部沿所述轮体中心圆周均布有多个弧形槽,所述弧形槽下方左右对称设置有弧形杆,两个所述弧形杆端部设置有限位端,所述弧形杆内活动设置有滑块,所述弧形槽内活动设置有离心球,所述滑块上设置有限位板,所述弧形杆外套设有用于将所述限位板朝所述离心球方向压紧的弹簧体,在运输设备停止移动时,脚轮自动和轮座产生摩擦,自动抱死脚轮,防止脚轮由于斜坡或者部分外力的影响导致自动移动的情况出现,防止移动后的运输设备产生的侧翻或倾倒等情况出现,保证财产和人生的安全,而且用力推动运输设备后,脚轮上的摩擦片逐渐脱离,缓慢的减少摩擦力,移动后,脚轮逐渐处于正常的旋转状态,设计合理,人性化。
