Description

Only multifunctional combined ladder of bar

Affiliated technical field

The utility model relates to the multifunctional combined ladder of a kind of only bar, particularly comprises the multifunctional combined ladder of being made up of mobile jib section of ladder, sliding skateboard body, pedal and annex thereof of only bar.Belong to daily utensil or emergency repair in emergency circumstances rescue utensil.It also is a kind of work implement of the operation of climbing to a higher point.

Background technology

Ladder is a kind of instrument of climbing to a higher point commonly used, is applied to place and height that the people can not arrive.Present ladder, generally by terraced bar and step on the retaining syndeton form.Because the height of ladder all sets in advance, wants to arrive different height, must use the ladder of differing heights, when employed ladder long enough, the carrying of ladder and difficulty thereof, and seem very heavy again.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes existing ladder defective technically, makes the length of ladder random combine and assemble become random length, not only solved the length issue of ladder, also makes the carrying of ladder and carries and convenient.And when having realized scaling a ladder, stride is not subjected to ladder to step on the retaining restriction, can climb arbitrarily, can arrive any height.The place of suitable emergency repair demonstrates small and exquisite, flexible, the motor-driven excellent properties of One pole ladder more.

The technical scheme that its technical problem that solves the utility model adopts is:

Ladder is linked by multistage mobile jib section of ladder and is combined into One pole ladder, the guide rail of its mobile jib section of ladder both sides is an integrative-structure with the mobile jib section of ladder, suit slide plate body on the guide rail, in the earhole seat of side pedal is housed, fixed by gudgeon, connect with coupling sleeve between each mobile jib section of ladder, be combined into the ladder of arbitrary height, on mobile jib section of ladder top, top, lateral means connects crossbeam, bottommost connects the assembling base, when the unlimited overtime of height of ladder, for preventing the bending when being subjected to gravity of terraced bar, support bar can also be installed in position, so, not only prevented the bending when being subjected to gravity of terraced bar, but also made the ladder strength-enhanced.The multifunctional combined ladder of this only bar that the utility model provides, volume is little, and is in light weight, safe and convenient to use, simple and reasonable, is a kind of ideal job engineering utensil of climbing to a higher point.

The beneficial effects of the utility model are, the height of ladder can winding become arbitrary height, make the carrying of ladder and carry and convenient, and when having realized scaling a ladder, stride is not subjected to ladder to step on the retaining restriction, can climb arbitrarily, and enlarge the scope of application of ladder.
