The invention discloses a swing type locking trundle which comprises a fixed installation part, a rotating wheel set and a brake part, the fixed installation part is used for being fixedly connected with an external foot column, the rotating wheel set is rotatably connected relative to the fixed installation part, the brake part is installed on the fixed installation part, and a plurality of lock holes distributed at intervals in the circumferential direction are formed in the fixed installation part; the rotating wheel set comprises a rotating disc, a rotating wheel and a locking unit, the locking unit comprises a locking rod, the rotating disc is rotatably connected with the fixed mounting piece, the locking rod can be matched with the locking hole after penetrating through the rotating disc, and the rotating wheel is rotatably connected with the rotating disc; the swing type locking trundle comprises an unlocking state and a locking state: in the unlocking state, the lock rod is separated from the lock hole, and the rotating wheel group can rotate relative to the fixed mounting piece; in the locking state, the brake piece is shifted, the brake piece drives the lock rod to be inserted into one lock hole, and the rotating wheel set is locked. The brake piece is installed on the fixed installation piece, and when the rotating wheel set rotates relative to the fixed installation piece, the brake piece does not rotate along with the rotating wheel set. Therefore, the brake piece is always kept at a relatively fixed position, and a user can conveniently operate the brake piece from the same direction.
本发明公开了一种摆动式锁止脚轮,包括固定安装件、转动轮组和刹车件,固定安装件用于与外部的脚柱固定连接,转动轮组相对于固定安装件可转动连接,刹车件安装在固定安装件上,固定安装件上设有多个沿圆周方向间隔分布的锁孔;转动轮组包括转盘、转轮和锁止单元,锁止单元包括锁杆,转盘与固定安装件可转动连接,锁杆穿过转盘后能够与锁孔配合,转轮与转盘可转动连接;摆动式锁止脚轮包括解锁状态和锁止状态:解锁状态时,锁杆与锁孔分离,转动轮组能够相对于固定安装件转动;锁止状态时,拨动刹车件,刹车件带动锁杆插入到其中一个锁孔中,转动轮组被锁止。本发明中将刹车件安装在固定安装件上,当转动轮组相对于固定安装件转动时,刹车件不跟随转动轮组一起转动。因此,刹车件始终保持在相对固定的位置上,便于用户从同一方位来操作刹车件。
