Abstract

A ladder capable of working for long comprises a main ladder and a subsidiary ladder movably connected with the main ladder, the uppermost pedal of the main ladder and the uppermost pedal of the subsidiary ladder are one-piece pedals, and the ladder is made of aluminum profile. The ladder capable of working for long is different from a ladder in the prior art in structure, the uppermost pedal of the main ladder and the uppermost pedal of the subsidiary ladder are one-piece pedals so that stability of the ladder is strengthened, the ladder is safe when used, and working hours of the ladder are prolonged. Due to the fact that width of the uppermost pedals of the ladder is increased, operating personnel can stand or sit on the ladder to work with no need to worry about unstability of the ladder. The ladder capable of working for long can be used as a ladder as well as a storage frame, does not need to be stored in a storeroom when not used as the ladder in the prior, can be placed at any place in a room, integrates functionality with beautiful appearance, and is good in safety and broadly suitable for being used in markets, offices, families, enterprises and public institutions, and schools.

Description

But a kind of ladder of long working

Technical field

The utility model relates to a kind of ladder, but particularly a kind of ladder of long working.

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, are stepping on pedal up, to arrive the destination.

Another comprises main ladder and secondary ladder, the two is to intersect and connects, main ladder and secondary ladder are all with 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 is by 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 owing to opening when using, can pack up when not using, be 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 the first structure need to depend on supporter, and the scope of application is less, though the second structure is good than the first structure, because its limitation, long working is had any problem.

Summary of the invention

Goal of the invention of the present utility model is to overcome the defective of prior art, provide a kind of rational in infrastructure, security performance good, long service life, needn't take storage space, but the ladder of long working.

The purpose of this utility model is achieved through the following technical solutions:

But a kind of ladder of long working comprises the main ladder and secondary ladder of flexible connection, and the upper level pedal of described main ladder and secondary ladder is the integral type pedal.

The material of described ladder is aluminium extruded sections.

The utility model can reach following beneficial effect after adopting technique scheme:

1, novel structure, firm.The utility model is different from the structure of the ladder of prior art, and the pedal of the upper level of its main ladder and secondary ladder is the integral type pedal, has strengthened the steadiness of ladder, and is safer during use.

2, the activity duration can increase.The utility model since the increase of the width of its higher level's pedal make the operating personnel can stand on for a long time (or being seated at) top operation, and needn't worry ladder built on the sand.

3, save the space.The utility model has been done a series of improvement for the defective of prior art, both can work as ladder and use, and also can work as storing stand and use, needn't as the prior art ladder, when not using, be accommodated in storeroom, can be put in the room Anywhere, be incorporated into one with functional with aesthetic property.

4, safety is better.After the utility model adopted this structure, safety factor increased greatly, therefore 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.Structure of the present utility model can be widely used in market, office, family, enterprises and institutions, school, adapts to society environmental protection needs.

8, long service life.The utility model structure is more firm, reliable than prior art, and long service life has wide market economy benefit.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Description of reference numerals

1, main ladder 2, integral type pedal 3, pedal 4, secondary ladder.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is described in further detail:

Referring to Fig. 1

Fig. 1 is structural representation of the present utility model.In Fig. 1, but the ladder of described a kind of long working, comprise main ladder 1 and secondary ladder 4, the side of described main ladder 1 and secondary ladder 4 is " people " font structure, main ladder 1 and secondary ladder 4 are flexibly connected, the pedal 3 of main ladder 1 can arrange arbitrarily (can be three grades or six grades etc.), upper level is integral type pedal 2 between main ladder 1 and the secondary ladder 4, be that (be located on the main ladder 1 by the one side that is integral type pedal 2 for the integral type structure for integral type pedal 2, the another side of integral type pedal 2 is located on the secondary ladder 4, the pedal of two ladders is an integral body), the area of integral type pedal 2 is at least twices of prior art pedal area, like this, on ladder, during operation, can stand reposefully on higher level's integral type pedal 2 (whenever necessary) as the operation personnel, because the load-bearing Area Ratio prior art of integral type pedal 2 is twice, therefore can stand on for a long time the top operation, firm, solid, and needn't worry the problem of crank.

But the material of described long working ladder can adopt aluminium alloys.

After the utility model adopts said structure, the lifting surface area of integral type pedal 2 is increased, the steadiness of ladder is better, has prolonged the activity duration on ladder.

Most preferred embodiment of the present 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 present utility model.

Claims (2)

1. but the ladder of a long working comprises it is characterized in that the main ladder and secondary ladder of flexible connection: the upper level pedal of described main ladder and secondary ladder is the integral type pedal.

2. but the ladder of a kind of long working according to claim 1, it is characterized in that: the material of described ladder is aluminium extruded sections.
