Abstract
The utility model discloses a multifunctional ladder used in families or public places. The existing ladder has two types, namely, an I-shaped ladder and an inverted V-shaped ladder, and the form and the function of the existing ladder are single. The multifunctional ladder used in families or public places not only can be used as the I-shaped ladder, but also can be used as the inverted V-shaped ladder, and also can be used as an escaping ladder for a building under emergency condition. The technical scheme of the ladder is as follows: one end of an upright post of the ladder is designed to be a one-fourth circular arc rotating relative to a pin shaft, the upright post of the ladder can rotate around the pin shaft fixedly connected on a pin shaft plate, and when two sides of the ladder rotate to be coincident, and lean against the wall, the ladder is in the I-shaped stable state and has certain strength and rigidity due to the combined action of the upright post, the pin shaft plate and the pin shaft. When in the inverted V-shaped ladder state, a detachable safety pull rope can be sheathed on pull rope pin columns at two sides of the ladder. A fixed hanger is arranged at one end of the ladder, so that the ladder can be hooked on the edge of a balcony or a window frame for people to escape under the emergency condition. In order to reduce the weight of the ladder, the ladder is made of aluminium alloy.
Description
Technical field:
The utility model relates to a kind of ladder, specifically, especially relates to a kind of ladder that is used for family or public place use.
Background technology:
Existing ladder has two kinds, and a kind of is 1 word ladder, and a kind of is double ladder, form and function singleness.
Summary of the invention:
The purpose of this utility model provides a kind of ladder that is used for family or public place, both can be used as 1 word ladder, also can be used as double ladder, in case of emergency can also be as building escape ladder.
In order to achieve the above object, the technical solution of the utility model is: an end of ladder two root posts is made 1/4 circular arc about the bearing pin center of rotation, because the unique texture of post end 1/4 circular arc can rotate, has the rotary spacing effect again.When two root posts of ladder forwarded a straight line to, because the rotary spacing effect, ladder two root posts formed the stable state of 1 word.When the double ladder state, detachable safe stay cord can be enclosed within on the stay cord pin on ladder both sides.One end of ladder column is equipped with fixed hook, is fixed on by steady pin on the column of ladder, and in case of emergency, fixed hook can hook the balcony limit or the window frame escape of building.For alleviating the weight of ladder, ladder adopts the aluminum alloy materials manufacturing.
