The invention discloses a guide mechanism which comprises a connecting body, a guide rod and a guide rod. The elastic anti-channeling guiding body is connected with the connecting body in an elastic structure mode, an anti-channeling guiding cambered surface for preventing channeling is arranged on the elastic anti-channeling guiding body, and a guiding structure which plays a guiding role and is used for forming a reverse meshing structure is connected to the anti-channeling guiding cambered surface; wherein the guide structure extends in a free state. The invention further discloses a worm and gear winch. The guide mechanism can effectively prevent the worm from axially moving in the transmission process, the transmission stability is improved, and the good transmission effect is guaranteed. Through the guide structure, automatic out-of-gear of the worm can be achieved, and rapid belt winding or unwinding operation can be easily achieved. The guide mechanism is integrally formed by punching, is provided with an elastic structure, can generate certain deformation, is high in strength, is not easy to break, cannot affect worm and gear transmission, is convenient to automatically disengage gears, and is time-saving and labor-saving in operation.

    本发明公开了一种导向机构,包括:连接体,所述的连接体上设置有插接固定片;弹性防窜导向体,与连接体呈弹性结构连接,所述的弹性防窜导向体上设置有防窜动的防窜导向弧面,所述的防窜导向弧面上连接有起导向作用且用于形成反向啮合结构的导向结构;其中,所述的导向结构呈自由状态延伸设置。还公开了一种蜗轮蜗杆绞车。该导向机构,能够有效防止蜗杆传动过程中的轴向窜动,提升传动的稳定性,保证良好的传动效果。通过导向结构可以实现蜗杆的自动脱档,可以轻松实现快速收带或放带操作。该导向机构整体冲压成型,设置有弹性结构,能够产生一定变形,强度高,不容易发生断裂,不会对蜗轮蜗杆传动造成影响,同时还方便自动脱档,操作省时省力。
