Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Such as figure 1 , a folding ladder, comprising a ladder frame body 1, the ladder frame body 1 is composed of two equal short ladder frames 2, the two short ladder frames 2 are connected by a shaft 3, and the two short ladder frames 2 can rotate along the shaft 3 at the connection point, On one side of the ladder body 1 , an anti-rotation ladder plate 4 is fixed on the shaft 3 . The folding ladder can be folded and stored or used by rotating on one side. It can also be rotated to use as a long ladder through the ladder boards. The two short ladder frames can be fixed by the ladder boards 4 to prevent rotation and cause danger.

[0015] The ladder board 4 is provided with a groove 5 protruding along the opposite direction of the short ladder for the rotation of the two short ladder frames 2 . The setting of the groove 5 is easy to rotate when it is convenient to rot...

Abstract

The invention discloses a folding ladder, belonging to the technical field of the folding ladder. A ladder frame body is formed by two uniform short ladder frames which are connected with each other by a shaft; the two short ladder frames can rotate along the axis of a connecting point; and an anti-rotating ladder plate is fixed at one side of the ladder frame body and on the shaft. According to the folding ladder, the ladder frame body is divided into the two ladders, so that the folding ladder does not depend on a support and can be easily placed after being folded; and if the height of the folded ladder does not meet the requirement, the folding ladder can be elongated into a straight ladder for use, thus being convenient and effective. The folding ladder overcomes the defect of independent long ladder or short ladder in the prior art.

Description

technical field [0001] The invention relates to a ladder, in particular to a folding ladder. Background technique [0002] Most of the ladder frames are used for maintenance or taking and placing high objects, but the current ladder frames are relatively simple, and some ladder frames are single-purpose, for example, they can only be folded or used as long ladders. Among them, sometimes a kind of ladder cannot meet our needs. It is too long and it is not easy to place it at home. It is too short, and sometimes it still cannot reach the desired height, so this is a very headache. Contents of the invention [0003] The present invention provides a folding ladder aiming at the shortcomings of the above-mentioned prior art, which solves the problem that the ladder is too long to be placed, and the ladder is too short to reach the use height. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A folding ladder, inc...
