Fixing structure for mounting pins on hook and hook bearing piece of hanging ladder
The fixing structure comprises the hook, the nail and the hook bearing piece, the hook comprises an upper surface and a side surface, the opposite surface of the side surface extends outwards and inclines downwards, the lower end of the side surface extends downwards, and the extending part inclines towards the opposite side direction of the side surface; the inner side surface of the hook is of an arc-shaped concave structure; the hook bearing piece is in a U shape, the contact position of the hook bearing piece and the hook is of an arc-shaped outwards-protruding structure, and the radian of the outwards-protruding structure is matched with the inwards-concave radian of the hook. A through hole is formed in the upper surface of the hook; the size of the through hole is matched with that of the nail; a through hole is formed in the hook bearing piece, the size of the through hole is matched with that of the through hole, and a nail penetrates through the hook bearing piece and the hook through the formed hole to fix the hook bearing piece and the hook; the nails are triangular nails or quadrangular nails. According to the invention, the phenomenon of accidental fall injury caused by missing hanging and virtual hanging can be avoided; and the falling damage phenomenon caused by the fact that one end is stressed and the other end is tilted and unhooked when the ladder is climbed due to uneven ground can be effectively avoided.
本发明公开了一种挂式梯挂钩与承钩件上装销钉的固定结构,包括挂钩、钉子和承钩件，挂钩包括上表面和侧表面，侧表面相对的一面向外延伸并向下倾斜，侧表面下端向下延伸，延伸的部分向侧表面对侧方向倾斜设置；挂钩内侧表面呈弧形内凹结构；承钩件为U型，承钩件与挂钩接触处呈弧形外凸结构，外凸结构的弧度与挂钩内凹弧度相匹配；挂钩上表面开设有贯穿孔，贯穿孔的尺寸与钉子的尺寸匹配；承钩件开设有通孔，通孔的尺寸与贯穿孔的尺寸匹配，钉子通过开设的孔贯穿承钩件和挂钩，固定承钩件和挂钩；钉子为三角钉子或四角钉子。本发明能避开漏挂、虚挂而造成意外摔伤的现象；能有效解决因地面不平，登梯时一端受力而另一端翘起脱钩造成摔伤现象。
