[0002] As a climbing tool, a ladder is generally made of bamboo or wood, and is used for people to go up and down step by step, and is used for high-altitude operations. However, traditional ladders are generally made of two long thick poles as sides, and the middle crosses a suitable for climbing. The cross bar is used as a foothold when climbing high. Therefore, when people go up and down the ladder, especially at the top of the ladder, due to various reasons such as unbalanced force, the ladder is easy to tip over or slide sideways. There is a great potential safety hazard due to the fall of personnel

Embodiment Construction

[0008] like figure 1 shown. A safety ladder, comprising a pole 1 and a crossbeam 2, the pole 1 is provided with a longitudinal wedge-shaped chute, a slide block 3 is arranged in the chute, a pull rope 4 is connected to the slide block 3, and the pull rope 4 is in addition One end is fixed on the locking hook 5, and the locking hook 5 is an adjustable hook with a flip-type locking pressing plate.

[0009] When in use, place the ladder at a certain angle of inclination correctly at the place where you need to ascend a height to perform operations, adjust the position of the slider 3 up and down according to the height of the fixable position, so that the locking hook 5 hooks the fixed object, and the rope is pulled like this 4, the ladder can be firmly pulled, and when people climb the ladder, the ladder will not overturn or slide sideways due to various reasons such as unbalanced force, thereby protecting the personal safety of the user and avoiding various accidents such as f...
