Abstract
A slipping-free one-way buckle includes a main body composed of a seat and a housing and containing therein two rollers, a turntable, a wheel, and a switching device. The switching device is arranged to project sideways from sidewalls of the seat and the housing and includes a tongue, a stop block, and a switching arm. By being connected with a spring, the stop block can be automatically returned after being displaced for switching so as to position the tongue against one-way ratcheting teeth formed on the turntable. With a rope extending around the turntable and the wheel, a slipping-free one-way buckle is formed. As such, when the switching device is switched by a user's finger, unlocking of buckle is realized.
