The gravity type quick release hook with the labor-saving reset function comprises a lifting lug plate, and a hole is formed in the lifting lug plate; the lifting lug plate is connected with two pulling plates through lifting lug shafts, the bottom ends of the pulling plates are connected with hook bodies through hook body shafts, and the lifting lug plate and the hook bodies are located between the two pulling plates; the gravity center of the hook body is located above the hook body shaft, the gravity center of the hook body is not collinear with the connecting line between the lifting lug shaft and the hook body shaft, and a hook opening of the hook body faces the gravity center side of the hook body. A blind hole is formed in the top of the hook body, and a first limiting piece is installed in the blind hole. A second limiting piece is rotationally connected between the two pulling plates, the top end of the second limiting piece is connected with one end of a reset tension spring, and the other end of the reset tension spring is fixedly connected with the two pulling plates through pin shafts. Through the arrangement of the resistance rod, the resistance for entering a self-unhooking state from a reset state is increased by utilizing the lever principle, and the hooking reliability and the manual intervention frequency are ensured; and through the arrangement of the spring bolt limiting mechanism, the manual operation intensity in the resetting process is reduced.
本发明公开一种带省力复位功能的重力式快卸钩,包括吊耳板,吊耳板上开设有孔;吊耳板通过吊耳轴连接有两个拉板,拉板的底端通过钩体轴连接有钩体,吊耳板和钩体均位于两拉板之间;钩体的重心位于钩体轴的上方,且钩体的重心与吊耳轴和钩体轴之间的连线不共线,钩体的钩口朝向钩体的重心侧;钩体的顶部开设有盲孔,盲孔内安装有第一限位件;两拉板之间转动连接有第二限位件,第二限位件的顶端连接有复位拉簧的一端,复位拉簧的另一端通过销轴与两拉板连接固定。本发明通过阻力杆的设置,利用杠杆原理增大了由复位状态进入可自脱钩状态的阻力,保证挂接可靠性和人工干预频次;通过锁舌限位机构的设置,降低了复位过程中人工操作强度。
