Abstract

The invention provides a folding ladder. The folding ladder comprises two pieces of ladders hinged together and lateral supporting rods arranged on the two sides of the two pieces of ladder respectively. The lateral supporting rods are a first lateral supporting rod arranged on the first side of the two pieces of ladder and a second lateral supporting rod arranged on the second side of the two pieces of ladder respectively; the first lateral supporting rod is a telescopic rod, the telescopic rod at least comprises a first section rod and a second section rod which are connected to each other, and the first section rod and the second section rod can stretch out and draw back oppositely; the first section rod and the second section rod are provided with multiple connecting holes with different heights respectively, dowel pins or positioning screws are arranged in the connecting holes, and the dowel pins or positioning screws in the first section rod and the second section rod are connected in a locating mode; the first section rod and the second section rod are rectangular rods; or cross sections of the first section rod and the second section rod are rectangular and groove-shaped. The folding ladder improves the safety performance of the lateral supporting rods.

Description

technical field [0001] The invention relates to a folding ladder. Background technique [0002] At present, folding ladders tend to topple sideways during use, causing injuries to people on the ladders. Although there have been foldable ladders that can be supported laterally, that is, lateral support rods are respectively arranged on both sides of the two ladders, but when the ladder is loaded, the lateral support rods are easy to bend sideways or even break, and still have a large Security risks. [0003] To sum up, the following problems exist in the prior art: a folding ladder with lateral support rods is easy to bend sideways or even break, which poses a serious safety hazard. Contents of the invention [0004] The invention provides a folding ladder to solve the problem that the lateral support rods are easy to bend sideways or even break, which poses a serious safety hazard. [0005] For this reason, the present invention proposes a kind of folding ladder, and de...
