Embodiment 1

[0036] The embodiment of the present invention provides a kind of ladder, refer to figure 1 As shown, the ladder includes a ladder body 110 and rungs 120 .

[0037] refer to figure 1 As shown, the number of ladder bodies 110 is two, and the ladder bodies 110 have a plate-like structure, and the two ladder bodies 110 are arranged opposite to each other. In this embodiment, the plate surfaces of the ladder bodies 110 are in the shape of a parallelogram.

[0038] refer to figure 1 As shown, the number of pedals 120 is multiple, and the pedals 120 are also plate-shaped structures. The multiple pedals 120 are located between the two ladder bodies 110, and the multiple pedals 120 are respectively perpendicular to the two ladder bodies 110. The multiple pedals 120 It is rotatably arranged between the two ladder bodies 110, and the distance between every two adjacent pedals 120 is the same, so that climbers can climb the ladder step by step. 120 friction.

[0039] Specifically, th...

Embodiment 2

[0062] The present invention also provides a combined ladder, which comprises the above-mentioned ladder, and one end of the two ladders is hinged to each other, so that the two ladders form a herringbone ladder, which is convenient for multiple people to work at the same time.

Abstract

The invention provides a ladder and a combination ladder, which belong to the field of living tools. The ladder includes two ladder bodies, a plurality of pedals and at least one connecting piece. The plurality of pedals are rotatably arranged between the two ladder bodies. At least one ladder The two ends of the body are respectively fixed with fixing parts, the fixing parts of the same ladder body are located inside, the connecting parts are respectively hinged with the pedals, and the connecting parts are slidably arranged on the two fixing parts of the same ladder body. The ladder has strong practicability and high safety performance.

Description

technical field [0001] The invention relates to the field of living tools, in particular to a ladder and a combined ladder. Background technique [0002] A ladder consists of two long thick poles on the sides, with a crossbar suitable for climbing across the middle, used for climbing. [0003] At present, the safety performance of the existing ladders is not high, and they are not suitable for being erected at positions of different heights, because it is easy to make people's center of gravity move backward, which is unfavorable for the safety of climbers. Contents of the invention [0004] The object of the present invention is to provide a ladder to ensure the safety of climbers and to adjust the pedals to always be in a horizontal state. [0005] Another object of the present invention is to provide a combined ladder. [0006] Embodiments of the present invention are achieved like this: [0007] A ladder, comprising two ladder bodies, a plurality of pedals and at le...
