According to the directional and universal switching type wheel provided by the invention, the directional piece is inserted into the directional hole of the fixed seat, so that the upper wheel seat cannot rotate freely, and a directional wheel is formed. The wheel rotates reversely, the pawl seat drives the pawl to rotate, the pawl is meshed with the ratchet wheel in the directional connecting piece, the directional connecting piece is pushed to rotate, the directional zipper is pulled, the directional piece is pulled out of the directional hole, the upper wheel seat can rotate freely, the wheel is changed into a universal wheel, and switching between the directional wheel and the universal wheel is completed. And the wheel rotates reversely again, the orienting piece rebounds into the orienting hole through the resilience force of the orienting reset spring, the wheel is changed into the orienting wheel, and switching between the universal wheel and the orienting wheel is completed. The directional and universal switching type wheel is installed on the stroller, the brake connecting rods are installed on the two sides of the frame pedal, one brake pedal can drive the two brake connecting rods to move at the same time, braking of the two wheels is completed at the same time, and therefore the function of one-step double-brake is achieved.

    本发明提出了一种定向及万向切换式车轮,通过定向件插入到固定座的定向孔中,使上轮座无法自由转动,形成定向轮。通过车轮反转,棘爪座带动棘爪转动,使棘爪与定向连接件内的棘轮啮合,推动定向连接件旋转,拉动定向拉锁,将定向件拉出定向孔,使上轮座能够自由转动,使车轮变为万向轮,完成定向轮与万向轮的切换。再次通过车轮反转,利用定向复位弹簧的回弹力,将定向件回弹到定向孔中,使车轮变为定向轮,完成万向轮与定向轮的切换。该定向及万向切换式车轮安装在儿童推车上,车架踏板的两侧均安装有刹车连杆,通过一个刹车踏板能够同时带动两个刹车连杆运动,完成两个车轮同时刹车,从而实现一踩双刹的功能。
