Abstract
The invention discloses a unidirectional rotation joint fork which comprises a joint fork body and a spline connection part. A joint fork portion is arranged at one end of the joint fork body, a spline installation hole is formed in the other end of the joint fork body, grooves are evenly formed in the spline installation hole, and the unidirectional curvature radiuses of the grooves gradually increase. One end of the spline connection part is inserted into the spline installation hole, a unidirectional block unidirectionally abutting against the spline installation hole is arranged at the end, a spring is arranged at the bottom of the unidirectional block, and a quick connection pin is arranged at the other end of the spline connection part. When the unidirectional block abuts against the spline installation hole, the unidirectional rotation joint fork can be clamped by the grooves when rotating forwards so that rotation limit can be achieved. The joint fork body and the spline connection part are relatively fixedly connected to achieve power transmission. When the unidirectional rotation joint fork rotates reversely, the unidirectional block can slide out of the grooves due to the fact that the curvature radiuses gradually increase, and therefore rotation of the spline connection part is achieved and the transmission function fails. Thus, the problem of equipment damage caused by reverse transmission is solved.
