Abstract

Disclosed is a triple-fold aluminum ladder, which is formed by sequentially connecting an upper component, an intermediate component and a lower component through moveable-hinge fixing bases, wherein the upper end of the upper component is connected with a footing guard strip, the lower component is equipped with a footing connection plate, and the upper component, the intermediate component and the lower component are formed by respectively connecting left and right main tubes to a plurality of crossbeam reinforcing tubes through a plurality of square holes, wherein the surfaces of the crossbeam reinforcing tubes are equipped with anti-skid bayonets. The hinge fixing base is formed by a left hinge fixed base and a right hinge fixed base via movable crossed joint, the view of the lateral face of the two butted fixing bases presents a U shape, the lateral face of one end is perpendicular to the surface, the lower side angle of the other end extends to form an ear hole structure with a movable connecting hole, thereby forming an abutted structure of the two movably connected fixing bases which present an M shape when unfolding and a V shape when folding, wherein one ear hole structure of the connecting base is inwardly bent to connect to the other connecting base in crossed joint form, and the left and right fixing bases are respectively equipped with two mounting holes for correspondingly connecting the left and right main tubes. The special hinge structure enables the aluminum ladder to be folded conveniently, and further, the aluminum ladder is light in weight, beautiful in appearance and convenient to move.

Description

Three folding aluminium ladders

Technical field

The utility model relates to a kind of folding ladder of aluminium extruded sections matter.

Background technology

Existing aluminium ladder structure is a lot, and the main characteristics of conveniently moving and moving with its light weight win the user and like.But its complex structure, the manufacturing cost height, assembling labour intensity is big, and aesthetics is not enough, and bearing capacity is also limited.

The utility model content

For this purpose, the utility model provides a kind of folding convenient, assembles three very strong folding aluminium ladders of practicality easily.

The technical scheme that the utility model provides, three folding aluminium ladders are constituted by an active connection by the hinges fixing reservation successively by last assembly, middle assembly and following assembly, last assembly upper end connects the footing guard strip, the footing guard strip with the inside bending angle in the junction of last assembly be 165 the degree, following assembly is provided with the footing junction plate, footing junction plate and following assembly become 152 degree to be connected, last assembly, middle assembly and time assembly by about the person in charge connect the surface respectively by a plurality of square openings and constitute with a plurality of crossbeam reinforced pipes of anti-skidding seam.

Above-mentioned hinges fixing reservation is formed by left hinges fixing reservation and right hinges fixing reservation activity fork-join, two holder side view main bodys structure that takes the shape of the letter U of butt joint, one end side surface and surface are vertical angle, side angle extends to form the earhole structure that band flexibly connects the hole under the other end, V-shaped syndeton that the holder that forms two flexible connections is the M type when packing up when opening, one of them inside bending of Connection Block earhole structure and another Connection Block fork-join, be provided with on the holder of the left and right sides with described about be responsible for two installing holes of corresponding connection.

Compare with existing aluminium ladder, above-mentioned aluminium type ladder light weight is convenient folding, and bearing capacity is big, move easily, and be a extraordinary fashion ladder type.

Below in conjunction with accompanying drawing the utility model is described in detail further.

The specific embodiment

For understanding concrete scheme of the present utility model, see also Fig. 1 to Fig. 7, Fig. 1 is the front view of three folding aluminium ladders.

Referring to Fig. 1, three folding aluminium ladders are constituted by an active connection by

hinges fixing reservation

4,5 successively by last assembly 1, middle assembly 2 and following assembly 3, last assembly 1 upper end connects footing guard strip 6, footing guard strip 6 with the inside bending angle in the junction of last assembly 1 be 165 the degree, following assembly 3 is provided with footing junction plate 7,1 one-tenth 152 degree of footing junction plate 7 and following assembly is connected, last assembly 1, middle assembly 2 and time assembly 3 by about be responsible for 8,9 and connect the surface respectively by a plurality of square openings and constitute with a plurality of crossbeam reinforced pipes 10 of anti-skidding seam.

Above-mentioned hinges fixing reservation is formed by left hinges fixing reservation 4 and right hinges fixing reservation 5 movable fork-joins, two holder side view main bodys structure that takes the shape of the letter U of butt joint, one end side surface and surface are vertical angle, side angle extends to form the earhole structure 11 that band flexibly connects the hole under the other end, V-shaped syndeton that the holder that forms two flexible connections is the M type when packing up when opening, one of them inside bending of Connection Block earhole structure and another Connection Block fork-join, be provided with on the holder of the left and right sides with described about be responsible for two installing holes of corresponding connection.

The Foldable aluminum ladder structure that the utility model provides, the quantity of its aluminium ladder crossbeam reinforced pipe is not subjected to this practicality Novel open the restriction, based on above design feature, present patent application disclosed by about be fixedly connected with The Foldable-type aluminum ladder structure that seat connects ought to be within protection domain of the present utility model.

Claims
