Abstract
The utility model provides a ladder capable of adjusting an inclined degree, comprising a ladder body, wherein the ladder body is at least divided into upper and lower parts; the two parts of the ladder are connected through a pulley wheel; a fixing piece for fixing is arranged at the connecting part of the ladder body and the pulley wheel; the fixing piece is arranged above the pulley wheel; and the ladder is made of an aluminum sectional material. Compared with the ladder in the prior art, the structure is different; the upper and lower parts of the ladder are connected through the pulley wheel; when the inclined degree of the ladder needs to be adjusted, only the upper part of the ladder needs to be adjusted to the needed height and is fixed by the fixing piece, so that the ladder can be suitable for different applicable ranges and the use is safer; the ladder does not need to occupy a larger space; when the ladder is not needed, the ladder can be folded (namely two ladders are parallel) to be stored; the ladder has a novel and beautiful structure and can meet the beauty appreciation requirements of simplicity and practical applicability of the modern society; the ladder can be widely applied to markets, offices, families and large-size warehouses; and compared with the prior art, the ladder is firmer and more reliable and has a long service life.
Description
Technical field
The utility model relates to a kind of ladder, particularly adjustable-pitch 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, supports ladder; 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, and the defective of oneself is respectively arranged, and first kind of structure need depend on supporter; The scope of application is less, and second kind of structure fixed: gradient is fixed, and is unadjustable; When not using, need be accommodated in storeroom, take certain space.
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, function is many, long service life, little adjustable-pitch ladder takes up room.
The purpose of the utility model realizes through following technical scheme:
Adjustable-pitch ladder comprises the ladder body, and said ladder body is divided into upper and lower two ones at least, connects through pulley between two ones on the said ladder, and said ladder body and pulley junction are provided with the fixture that is used for fixing.
Said fixture is located at the pulley top.
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; It is divided into up and down, and two ones ladder body connects through pulley; When needs are regulated the angle of inclination of ladder,, fix with fixture as long as the top of ladder is adjusted to the angle that needs; Then ladder can satisfy different applicable situations, and is safer during use.
2, regulate arbitrarily.The utility model is owing to be divided into two parts with ladder, and the centre connects (being equivalent to the joint) with pulley, when needs are regulated the angle of inclination of ladder, ladder top is transferred to required angle, fixes with fixture then, can reach required angle easily.
3, save the space.The utility model has been done a series of improvement to the defective of prior art, need not to take too many space, and when not required, only need taken in ladder folding (being that two ones on ladder is parallel) and get 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 novel structure, 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 the 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Description of reference numerals
1, the bottom 2 of ladder body, pulley 3, fixture 4, ladder upper part of body.
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 adjustable-pitch ladder comprises the ladder body that has pedal, and said ladder body is divided into the bottom 1 and ladder upper part of body 4 of ladder body; Said two ones are passed through pulley 2 connections, are provided with the fixture 3 that is used for fixing in the junction of pulley 2 and ladder body.
When needs are regulated the ladder gradient, can ladder upper part of body 4 be adjusted to the angle (because this moment, pulley 2 was equivalent to the joint) that needs, fixing with fixture 3 then, the angle that promptly can freely regulate ladder can adapt to any applicable situation.
Another characteristics of the utility model are: at the needs ramp period of the day from 11 p.m. to 1 a.m; Can ladder be packed up (this moment, the bottom 1 of ladder body was parallel rugosity with ladder upper part of body 4); Slide on ground with pulley, laborsaving, when not using ladder; Ladder area occupied after then folding is less, has saved the space.
The material of said adjustable-pitch ladder can adopt aluminium alloys.
The utility model can regulate the angle of inclination of ladder arbitrarily after adopting said structure, and steadiness is better, can be suitable for any occasion.
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.
