The purpose of this utility model and provides a kind of with for building of angular adjustment aiming at the deficiency of prior art
Double ladder, it can realize the angular adjustment and positioning between double ladder ladder, be easy to double ladder highly to adjust and position.
A kind of double ladder for building with angular adjustment, including left ladder and right ladder, if left ladder and right ladder by
Dry hinge is hinged, and the side wall of left ladder is fixed with bottom bar, and the both ends of bottom bar form pillar, and one end of adjusting rod is hinged on
The regulating tank of bar shaped is formed on the pillar of bottom bar lower end, on adjusting rod, locating dowel is plugged with regulating tank, locating dowel is fixed on
In the side wall of right ladder, the neck of several circular arcs is formed on the lower surface of adjusting rod；One end shaping of gag lever post is limited
Position post, limited post are plugged in the neck of adjusting rod, and the other end of gag lever post forms waist-shaped hole, the pillar grafting of bottom bar upper end
One end that waist-shaped hole is closed in the waist-shaped hole of gag lever post, on gag lever post forms journal stirrup, and bolt is bolted with journal stirrup.
The pillar of the bottom bar or the top of locating dowel form block, and the pillar upper sleeve of bottom bar upper end has spacer,
Gag lever post is located at the rear side of adjusting rod, and the block of locating dowel is resisted against on adjusting rod, and the block of bottom bar upper and lower end pillar supports respectively
Lean against on spacer and adjusting rod.
The diameter of the limited post is equal to the arc diameter of neck on adjusting rod, and the circular arc radian of neck is more than on regulating tank
The circular arc radian of semicircle.
Described neck is linearly evenly distributed on adjusting rod.
The beneficial effects of the utility model are：
It is simple in construction, and there is provided angle adjusting mechanism on double ladder, so as to realize the angle between double ladder ladder
Degree regulation and positioning, are easy to double ladder highly to adjust and position.
Brief description of the drawings：
Fig. 1 is the three-dimensional structural representation of the utility model；
Fig. 2 is the dimensional structure diagram of another angle of the utility model；
Fig. 3 is the structural representation that the utility model is faced.
In figure：1st, left ladder；2nd, right ladder；3rd, bottom bar；31st, pillar；4th, adjusting rod；41st, regulating tank；42nd, neck；5th, it is fixed
