Problems solved by technology
A simple single ladder is generally composed of two supporting beams on the left and right and several beams fixed horizontally between the two supporting beams. This single ladder has a simple structure, but it takes up a lot of space and is inconvenient to store.
There are also telescopic single ladders now, mainly because the supporting beam is designed as a telescopic structure, and the volume is greatly reduced when stowed away, but this design structure is complicated, it is more troublesome to open, and the cost is also higher

The invention discloses a foldable single ladder, which comprises left and right support beams which are in parallel and multiple cross bars, wherein each cross bar comprises left and right cross bars, the right end of each left cross bar is hinged with the left end of each right cross bar, the left end of each left cross bar and the right end of each right cross bar are respectively hinged on the left and right support beams, and the left and right support beams are both provided with check blocks at the positions below the hinged parts of the left and right support beams and the left and right cross bars. According to the foldable single ladder disclosed by the invention, the cross bars are designed to left and right cross bars which are hinged together, and the left and right cross bars are respectively hinged with the left and right support beams, thus realizing the purpose that the left and right support beams can be folded in an attached mode. The structure is simple and the use is very convenient.
Description
technical field [0001] The invention relates to a single ladder, in particular to a foldable single ladder. Background technique [0002] Single ladders are widely used in people's work and daily life. A simple single ladder is generally composed of two left and right supporting beams and a number of beams fixed horizontally between the two supporting beams. This single ladder has a simple structure, but it takes up a lot of space and is inconvenient for storage. There are also telescopic single ladders now, mainly the support beam is designed as a telescopic structure, and the volume is greatly reduced when it is put away, but this design has a complicated structure, and it is more troublesome to open, and the cost is also higher. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a foldable single ladder with simple structure. [0004] The technical scheme that the present invention solves the problem adopts i...
