Abstract

The invention provides a ladder. The ladder comprises a fixed base, pedals, a first connecting part and a first limiting part, wherein the pedals comprises a first pedal and a second pedal; the first pedal is located between the fixed base and the second pedal and is provided with a first-pedal first end facing the fixed base and a first-pedal second end away from the fixed base; the second pedal is provided with a second-pedal first end facing the fixed base and a second-pedal second end away from the fixed base; the first-pedal first end is rotatably arranged on the fixed base; the first end of the first connecting part is rotatably connected with the first-pedal second end, and the second end of the first connecting part is rotatably connected with the second-pedal first end; the first limiting part is arranged on the fixed base to stop downward rotation of the first pedal; and the ladder has a folding position and an unfolding position, and the first connecting part is fixed with the first pedal through a first fixed part when the ladder is in the unfolding position. The ladder provided by the invention overcomes the problem that conventional ladders occupy great space when not in use.

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...
