The invention discloses a Japanese type heavy universal PU trundle which comprises a trundle frame. The rollers are rotationally arranged at the bottoms of the trundle frames; the mounting disc is rotationally arranged at the top of the trundle frame; the brake mechanism comprises a positioning frame, an unlocking piece, a locking piece and a brake piece, the positioning frame is positioned at the front end of the trundle frame, the unlocking piece and the locking piece are rotationally connected to the positioning frame, a second side plate of the unlocking piece is provided with a reset guide groove, the reset guide groove is communicated with a brake groove in the side face, and a third rotating shaft on the locking piece is slidably arranged between the reset guide groove and the brake groove. The brake piece is positioned at the bottom of the locking piece, and a reset assembly is arranged among the positioning frame, the unlocking piece and the locking piece. By means of the trundle braking mechanism, the problems that when an existing trundle braking mechanism is locked and unlocked, the movement resistance of an internal structure is large, the jamming condition exists, the structural stability is insufficient during braking, the braking quality is poor, and the existing trundle braking mechanism cannot be suitable for a heavy trundle can be solved.
本发明公开了一种日式重型万向PU脚轮,包括:脚轮架;滚轮,其转动设置于脚轮架底部;安装盘,其转动设置于脚轮架顶部;刹停机构,包括定位架、解锁件、锁止件以及刹车件,定位架定位在脚轮架前端,解锁件、锁止件分别转动连接在定位架上,解锁件的第二侧板上设置复位导槽,复位导槽连通侧面的刹停槽,锁止件上的第三转轴滑动设置于复位导槽、刹停槽之间,刹车件定位在锁止件底部,定位架、解锁件、锁止件之间设置复位组件。本发明可以解决现有脚轮的刹停机构锁止、解锁操作时内部结构活动阻力大,存在卡死情况,且刹停时结构稳定性不足,使得刹停质量较差,无法适用于重型脚轮的问题。
