The invention provides a ladder. The ladder comprises a fixed base, a pedal, a first connecting part and a second connecting part, and a third connecting part and a fourth connecting part, wherein the pedal comprises a first pedal and a second pedal; the first pedal has a first pedal first end and a first pedal second end; the first pedal first end is rotationally arranged on the fixed base; the first pedal second end is provided with a first extension part; the first extension part is rotationally connected with the second pedal first end; a first end of the first connecting part is rotationally arranged on the fixed base; a second end of the first connecting part and a first end of the second connecting part are connected in a relative rotating manner; a second end of the second connecting part is rotationally connected to the first pedal; a first end of the third connecting part is rotationally connected to the first pedal; a second end of the third connecting part and a first end of the fourth connecting part are connected in a relative rotating manner; and a second end of the fourth connecting part is rotationally connected to the second pedal. The ladder solves the problem of large occupying space when the ladder is not used.
Description
technical field [0001] The invention relates to the technical field of engineering machinery tools, in particular to a ladder. Background technique [0002] Ladders in the prior art are fixed on machines or objects by welding or bolts. Such as figure 1 as shown, figure 1 Ladder 1 in takes up too much space. Such as figure 2 as shown, figure 2 The ladder in 2 is not comfortable to step on. The existing ladder takes up a lot of space when not in use. Contents of the invention [0003] The main purpose of the present invention is to provide a ladder to solve the problem in the prior art that the ladder takes up a lot of space when it is not in use. [0004] In order to achieve the above object, the present invention provides a ladder, comprising: a fixed base; pedals, including a first pedal and a second pedal, the first pedal is located between the fixed base and the second pedal, the first pedal has a The first pedal first end and the first pedal second end away f...
