Summary of the invention
The purpose of this utility model provides a kind of pillar and pedal can closely recline, the folding ladder that folding effect is good.
The utility model is provided with left pillar, right pillar and at least 2 pedals, and each pedal is located between left pillar and the right pillar, and the identical U font pillar that is with right pier construction of left pillar is all hinged between the biside plate of U font pillar and the base plate; Every pedal structure is identical, every pedal is provided with left-hand tread plate and right-hand tread plate, the identical U font pedal that is of left-hand tread plate with the right-hand tread plate structure, all hinged between the biside plate of U font pedal and the base plate, hinged between the right-hand member of left-hand tread plate and the left end of right-hand tread plate, hinged between the left end of left-hand tread plate and the base plate of left pillar, hinged between the right-hand member of right-hand tread plate and the base plate of right pillar, be provided with fastener between the biside plate of left-hand tread plate and the biside plate of left pillar, be provided with fastener between the biside plate of right-hand tread plate and the biside plate of right pillar.
Described left pillar and right pillar constitute by at least 2 joint pillars, and each saves between the pillar hinged.
The described hinged loose-leaf that adopts is hinged.
Described fastener can adopt the buckle-type fastener, is provided with the convex clip head on the biside plate of left-hand tread plate, and correspondence is provided with recessed card cap on the biside plate of left pillar, and the convex clip head embeds in the recessed card cap; Be provided with the convex clip head on the biside plate of right-hand tread plate, correspondence is provided with recessed card cap on the biside plate of right pillar, and the convex clip head embeds in the recessed card cap.
Described fastener can adopt the inserting bolt type fastener, is provided with inserting bolthole on the biside plate of left-hand tread plate, and correspondence is provided with inserting bolthole on the biside plate of left pillar, and plug crosses inserting bolthole and the locking on the biside plate of inserting bolthole on the biside plate of left-hand tread plate and left pillar; Be provided with inserting bolthole on the biside plate of right-hand tread plate, correspondence is provided with inserting bolthole on the biside plate of right pillar, and plug crosses inserting bolthole and the locking on the biside plate of inserting bolthole on the biside plate of right-hand tread plate and right pillar.
Compared with the prior art, the utlity model has following outstanding advantage:
Because the biside plate and the base plate of U font pillar are all hinged, all hinged between the biside plate of U font left-hand tread plate and the base plate, all hinged between the biside plate of U font right-hand tread plate and the base plate, so all turning formation tabular of opening of U font pillar, U font left-hand tread plate and U font right-hand tread plate; Because hinged between the left end of the right-hand member of left-hand tread plate and right-hand tread plate, so can overturn relatively between left-hand tread plate and the right-hand tread plate and folding by subsides; Because it is hinged between the right-hand member of left-hand tread plate and the left end of right-hand tread plate; Hinged between the left end of left-hand tread plate and the base plate of left pillar, therefore, left-hand tread plate base plate collapsible and left pillar reclines, right-hand tread plate base plate collapsible and right pillar reclines, ladder can be folded into the very little state of thickness at last like this, be that thickness is about: the base plate thickness of left pillar adds the base plate thickness of right pillar, adds the base plate thickness of left-hand tread plate and the base plate thickness of right-hand tread plate.In addition because left pillar and right pillar can constitute by at least 2 joints are column articulated, therefore be folded to minimum thickness after, also can be again that pillar is folding, the length of ladder is shortened.This shows that folding effect of the present utility model is good, it is little to take up room, easy to store and carry.
