The invention discloses a quick, labor-saving and reliable antiskid chain locking device which comprises a shell, an eccentric driving shaft, a driven locking wheel disc, a planet cycloid gear, a driving retaining piece and connecting discs; two ends of the eccentric driving shaft are rotationally installed on the shell; the eccentric driving shaft comprises a first concentric shaft, an eccentricstep and a second concentric shaft; the driven locking wheel disc is installed on the first concentric shaft; an inner gear ring is arranged on one side of the driven locking wheel disc; the planetarycycloid gear is mounted on the eccentric step and engaged with an inner gear ring; a square step is arranged on one side of the planetary cycloid gear; a square hole is formed in the driving retaining piece; the square step is inserted into the square hole; two guide baffles are arranged on the opposite inner sides of a second clamping plate; the driving retaining piece is arranged between the two guide baffles; the connecting discs are arranged on the periphery of the driven locking wheel disc in a surrounding mode; and all the connecting discs are connected with the driven locking wheel disc through pull wires. With the quick, labor-saving and reliable antiskid chain locking device adopted, the problems of labor-wasting, time-wasting and labor-wasting performance and insufficient locking force during the locking of a chain of an existing locking device can be solved.
本发明公开了一种快捷省力可靠的防滑链锁紧装置,包括外壳、偏心驱动轴、被动锁紧轮盘、行星摆线齿轮、驱动止退片和连接盘;偏心驱动轴的两端转动安装于外壳,偏心驱动轴包括第一同心轴、偏心台阶和第二同心轴三段;被动锁紧轮盘安装于第一同心轴,被动锁紧轮盘的一侧设有内齿圈;行星摆线齿轮安装于偏心台阶并与内齿圈啮合,行星摆线齿轮的一侧设有方形台阶;驱动止退片上设有方孔,方形台阶插入方孔内,第二夹板的相对内侧设有两块导向挡板,驱动止退片设于两块导向挡板之间;连接盘环绕设于被动锁紧轮盘的四周,各连接盘分别通过拉线与被动锁紧轮盘相连。本发明有效解决了现有的锁紧装置在锁紧链条时费工、费时、费力、锁紧力不足的问题。
