Description
Technical field
The utility model relates to a kind of ladder, particularly a kind of ladder of extensible length.
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, and the defective of oneself is respectively arranged, and first kind of structure need depend on supporter, and the scope of application is less, and second kind of structure height fixed, and can't satisfy the requirement of different applicable situations.
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, the ladder of extensible length.
The purpose of the utility model realizes through following technical scheme:
