The invention provides a lifting hook locking structure, and relates to the field of rope self-locking. Comprising a first mounting part and a second mounting part which are connected with each other and arranged between a first cover plate and a second cover plate, the first mounting part is connected with a first cover body, a column body used for binding a lifting rope is arranged on the lower side of the second mounting part, and a first spring, a first gear and a guide column are sequentially arranged on the upper side of the second mounting part; a disc is arranged at the bottom of the first gear, a hollow structure used for installing a guide column is formed in the middle of the first gear, a second gear meshed with the first gear is arranged on the bottom side of the second cover plate, and the second cover plate is provided with a pressing structure used for driving the first gear and the second gear to be separated. When the pressing structure is not used, the first gear and the second gear are meshed and the first gear rotates unidirectionally; the pressing structure is continuously pressed down, the first gear and the second gear are separated, and the first gear rotates bidirectionally; when the pressing structure is released, the first gear and the second gear are meshed again.
本发明提出了一种吊钩锁紧结构,涉及绳索自锁领域。包括:第一盖板和第二盖板之间设置有彼此连接的第一安装件和第二安装件,第一安装件与第一盖体连接,第二安装件的下侧设置有用于绑定吊绳的柱体,第二安装件的上侧依次设置有第一弹簧、第一齿轮以及导向柱,第一齿轮的底部设置有圆盘,第一齿轮的中部开设有用于安装导向柱的空心结构,第二盖板的底侧设有与第一齿轮啮合的第二齿轮,第二盖板设置有用于驱动第一齿轮和第二齿轮分离的按压结构;未使用按压结构,第一齿轮和第二齿轮啮合且第一齿轮单向转动;持续按下按压结构,第一齿轮和第二齿轮分离且第一齿轮双向转动;松开按压结构,第一齿轮和第二齿轮再次啮合。
