Abstract
A combined type ladder comprises a main ladder and an auxiliary ladder, and the main ladder and the auxiliary ladder are hinged in an inverted-V shape. A secondary ladder is installed above the main ladder in a sliding mode and connected with the main ladder through a rail. A fixing piece used for fixing is arranged on the secondary ladder, ladder feet are disposed at the bottom of the auxiliary ladder, and the ladder is made of aluminium section bars. The structure of the combined type ladder is different from that of a ladder in the prior art. Because the secondary ladder is further added on the main ladder, when the length of the ladder needs extending, the secondary ladder is stretched out along the rail and then fixed by the fixing piece (can be a connector clip), so that the needed height is conveniently reached. The combined type ladder is longer than a common ladder and can be widely used in a market, an office, an enterprise and public institution, a school, a family and a large-scale storage.
Description
Technical field
The utility model relates to a kind of ladder, particularly combined ladder.
Background technology
The ladder of prior art generally has two kinds: a kind of ladder and pedal of comprising, and ladder and pedal are affixed, and people are overlapped on the body of wall or support that needs the in-position with the top of ladder in use, and it is up to step on pedal, to arrive the destination.
A kind of in addition main ladder and secondary ladder of comprising, the two is to intersect and connects, and main ladder and secondary ladder all have pedal, when using; Ladder is opened, be " eight " font, all can arrive the destination from main ladder and secondary ladder, the ladder of this kind structure leans on himself support structure; Need not rely on other supporters, and the master is terraced and the foot of ladder of pair ladder is positioned on the horizontal plane, the two is double-legged braced structures; Support ladder and keep vertical structure, climb up by holding on to uply for the user, this structure is more firm; And opening during owing to use, can pack up when not using, is the structure of generally using at present.
But above-mentioned two kinds of structures are traditional ladder structure; The defective that oneself is respectively arranged, first kind of structure need depend on supporter, and the scope of application is less; The height of second kind of structure is restricted; Be up to and reach the top that the position can only be " eight " font structure of ladder, cannot raise again, certain limitation is arranged.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provide a kind of rational in infrastructure, security performance good, long service life, can raise the height, little combined ladder takes up room.
The goal of the invention of the utility model realizes through following technical scheme:
Combined ladder comprises being hinged main ladder of " eight " font and secondary ladder to slide and be provided with a son ladder in the top of said main ladder, and said son ladder is connected with main ladder through track, and said sub-ladder is provided with the fixture that is used for fixing the position.
The bottom of said secondary ladder is provided with foot of ladder.
The material of said ladder is an aluminium extruded sections.
The utility model can reach following beneficial effect after adopting technique scheme:
1, novel structure, firm.The utility model is different with the structure of the ladder of prior art, and the sub-ladder that its main ladder is provided with can rise along track, when needs extend ladder length, can the son ladder be raise, and fixes with fixture then, makes ladder can arrive higher place.
2, highly extend.The utility model, stretches out the son ladder when needs extend ladder length owing on main ladder, set up a son ladder again along track, be fixed to the height that needs with fixture (can be plug connector) again, can reach required height easily.
3, save the space.The utility model has been done a series of improvement to the defective of prior art, though more common ladder is long, need not to take too many space, and when not needing development length, the length that only needs ladder to be received extremely main ladder gets final product.
4, safety is better.After the utility model adopted this structure, safety factor increased greatly, so safety is better.
6, attractive in appearance.The utility model structure is attractive in appearance, possesses succinct, the practical esthetic requirement of modern society.
7, applied widely, environmental protection.The structure of the utility model can be adaptable across enterprises and institutions, school, market, office, family, and bulk storage plant adapts to current social enviroment protection needs.
8, long service life.The utility model structure is more firm, reliable than prior art, and long service life has the vast market economic benefit.

1, main ladder 2, track 3, son ladder 4, fixture 5, articulated elements 6, secondary ladder 7, secondary foot of ladder 8, connector.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain:
Referring to Fig. 1
Fig. 1 is the structural representation of the utility model.In Fig. 1; Said combined ladder comprises the main ladder 1 and the secondary ladder 6 that have pedal, and the side of said main ladder 1 and secondary ladder 6 is " eight " font structure of top butt joint; Main ladder 1 is hinged through articulated elements 5 with secondary ladder 6; The top of main ladder 1 also is provided with a son ladder 3, and son ladder 3 is slidingly connected through track 2 and main ladder 1, and son ladder 3 is provided with the fixture 4 that is used for fixing.
When needs arrive the height be higher than main ladder 1 and secondary terraced 6 tops, son ladder 3 is extended upward along track 2, when treating, sub-ladder is fixed to applicable position with fixture 4 to the needs height, the user can be along main ladder 1 and son ladder 3 arrival desired heights.
Can also set up connector 8 between said main ladder 1 and the secondary ladder 6, be used to strengthen the steadiness between each ladder.
Another characteristics of the utility model are: set up a son ladder 3 on the top of main ladder 1, main ladder 1 and son ladder 3 are slidingly connected through track 2, and son ladder 3 is provided with the fixture 4 that is used for fixing, and when needs during again along elongation, son ladder 3 can extend along track.
The material of said combined ladder can adopt section bar.
After the utility model adopted said structure, the length that makes ladder was greatly along stretching, and steadiness is better, can need the occasion of extra-high-speed ladder to use in bulk storage plant and villa etc.
The most preferred embodiment of the utility model is illustrated, and the further expansion that those of ordinary skill in the art makes according to the utility model all falls in the protection domain of the utility model.
