The invention relates to a telescopic herringbone ladder which comprises a front ladder frame, a rear ladder frame and connecting lugs, wherein the front ladder frame comprises a front inner ladder frame and a front outer ladder frame, the rear ladder frame comprises a rear inner ladder frame and a rear outer ladder frame, the front inner ladder frame and the rear inner ladder frame are connectedwith the connecting lugs respectively, and the front inner ladder frame and the rear inner ladder frame mutually expand or fold through the connecting lugs; the front outer ladder frame is movably connected with the front inner ladder frame, the front outer ladder frame expands and contracts in the height direction of the front inner ladder frame to adjust the height of the front ladder frame, locking devices are arranged between the front inner ladder frame and the front outer ladder frame, and the locking devices lock the telescopic state of the front inner ladder frame and the front outer ladder frame; and a user can freely adjust changes to the rear inner ladder frame and the rear outer ladder frame, so as to adjust the height of the rear ladder frame, and when the height of the frontladder frame and the height of the rear ladder frame are changed, the height of the herringbone ladder can be changed, and the herringbone ladder can be adjusted for different heights; and due to themulti-position height telescopic adjustment, the herringbone ladder can be adapted to operation requirements of different heights, therefore, the practicability of the herringbone ladder is improved.
Description
technical field [0001] The invention relates to a telescopic ladder. Background technique [0002] The ladder is very popular among consumers because of its self-supporting structure (no need to lean against the wall) and a working platform for easy work. [0003] Since consumers need ladders of different heights to match different usage occasions, they often need to equip several ladders at home, which wastes money and takes up space. [0004] Due to the above-mentioned reasons, the height of the ladder cannot be adjusted as required, and cannot meet user needs. Contents of the invention [0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a safe and reliable telescopic ladder that can be adjusted in height. [0006] The purpose of the present invention is achieved like this: [0007] A telescopic miter ladder, comprising a front ladder frame, a rear ladder frame and connecting ears, the front ladde...
