Abstract

The utility model discloses but multi -functional aerial ladder be the combination of three list ladder make stretch in succession the aerial ladder that draws can not have rely on a little stretch the ladder length of drawing also the single face lean on the wall to raise the ladder to solve the various shortcoming and defect that have the ladder now, convenient and practical.

Description

Multi-functional aerial ladder

Technical field

The utility model relates to a kind of ladder of aluminum alloy.Specifically there are 3 or 4 single ladders to close to make and can stretch the aerial ladder drawn continuously, can elongate or shorten according to different height, and ladder can be diverged to stand rising.Used aloned can be taken apart or combine multiple use, closing rear ladder small volume, convenient and practical.This technology selects the aerial ladder analytic explanation that can divide three layers.

Background technology

Existing aluminum alloy ladder on the market has two kinds: a kind of is the ladder that can raise drawn with rope, this ladder is that one side leans on wall, can not use without fulcrum, and have inconvenience during the rope drawing ladder to raise ladder upper and lower to people, another kind can be divided into both legs and stand by jag, or extended legs with thighs one side is by the ladder of wall, self can not raise after this ladder both legs fork, can not use flexibly when the space limited or height, can not to stand after extended legs with thighs use, these two kinds of ladders are all that two ladders combine, reach most two terraced length, can not push-and-pull raise continuously, it is longer after ladder closes, carry and deposit all inconveniences.

Summary of the invention

The utility model aluminium alloys aerial ladder can without rope stand with one foot to the knee push-and-pull raise, also can diverge ladder both legs to stand, push-and-pull raises, and the used aloned or combinationally use of breaking, closing is a ladder height, and close to three ladder height when raising, volume is little, easy to carry, solve the various shortcoming and defect of existing ladder.

The utility model aluminium alloys aerial ladder is achieved mainly through following technical proposals, described aerial ladder is by three single ladders from narrow to wide side by side, the terraced headgear of the second ladder and the 3rd ladder band pipe is entered in a upper terraced groove, and together, the following push-and-pull ladder makes it to raise or reduce by three ladder connected sets.

Therefore the utility model aerial ladder has the following advantages:

1, the free adjustable height of energy in certain altitude,

2, need not to restrict power elevation, convenient and safe.

3, can single leg land or both legs land push-and-pull raise.

4, ladder liter draws high Du Genggao, closes rear volume less, easy to carry.

5, detachable used aloned and combinationally using.
