The invention discloses a cam-based universal wheel axle frame locking mechanism with a manual control function, and relates to a universal wheel self-locking mechanism. The main components are a modified pull rod part and a rotary disc cam part. A pull rod of a traditional pull box is used for starting the self-locking device, so that the structural complexity is reduced; the brake can be started by directly lifting the pull box by grasping the pull rod; the pull rod drives a rotating disc to rotate within a certain angle through a connecting rod, the rotating disc presses a cam in a higher pair contact mode, the cam points to a specific direction by means of guidance of the cam, and then the universal wheel fixedly connected with the cam points to the specific direction. Two or more universal wheel shaft frames can be locked at the same time according to the design, and efficient braking is achieved. According to the mechanism, the universal wheel body is not required or optionally not modified, so that the reliability and durability of the universal wheel are ensured. The device has the advantages that original parts are utilized, the structure is simpler and more reliable, braking is more convenient, locking or unlocking is easier, and market requirements can be better met.

    本发明公开了一种基于凸轮带有手控的万向轮轴架锁紧机构,涉及万向轮自锁机构;主要组成部分为改装后的拉杆部分和转盘凸轮部分;该自锁装置的启用利用了传统拉箱的拉杆,减少结构复杂性;通过抓住拉杆直接提起拉箱即可启动刹车;拉杆通过连杆驱动一转盘在一定角度内旋转,转盘通过高副接触的方式压紧凸轮,利用凸轮的引导性,使凸轮指向特定的方向,进而使与凸轮固接的万向轮指向特定方向。可根据设计同时锁紧两个或多个万向轮轴架,实现高效刹车。该机构无需或可选的不对万向轮本体进行改装,保证了万向轮的可靠性和耐用性。本装置有着利用原有零件、使结构更简单可靠、刹车更方便、锁止或解锁更轻松以及更能适应市场需求等有益效果。
