The existing ladder for building proposed in art is the Shortcomings on stability maintenance and controllability the problem of.
The terraced purpose and effect for building of the utility model adjustable tilt angle, are reached by technological means in detail below
Into：
A kind of ladder for building of adjustable tilt angle, wherein, the ladder for building of the adjustable tilt angle includes：
Main ladder support, secondary ladder, main pillar, top plate, crossbeam, jury strut, cradling piece, angle adjustment holes, support arm, pedal,
Extension bar and length-adjustment holes；
The main ladder support is made of two main pillars and the top plate and crossbeam that are connected between main pillar；The pair ladder
Top the inner side of main ladder support is articulated with by axis pin；The pair ladder includes support arm and the pedal structure being connected between support arm
Into；The support arm is equipped with angle adjustment holes；One end of the cradling piece is articulated with main pillar by axis pin, and cradling piece
The other end is articulated with the angle adjustment holes on support arm by axis pin；The bottom of the support arm is equipped with length-adjustment holes；It is described to add
Stock is movably installed in the length-adjustment holes on support arm by axis pin.
Further, the secondary ladder altogether can a point three-level adjust, its adjustable-angle scope is 15 °.
Further, the jury strut is bolted the outside for being installed on main pillar.
With existing structure in comparison, the utility model has the following advantages that：
1. the utility model has the secondary ladder of adjustable-angle, secondary ladder is adjustable for three-level, and is adjusting secondary ladder
During angle, main ladder support can keep vertical angle constant, by the adjusting to secondary ladder angle, make the utility model more
Suitable for the use in construction place.
2. the utility model is equipped with jury strut in the both sides of main ladder support, the stress point of ladder is disperseed, has improved ladder
Stability.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model side structure schematic view.
In figure：11st, main ladder support, 22, secondary ladder, 1, main pillar, 2, top plate, 3, crossbeam, 4, jury strut, 5, cradling piece,
6th, angle adjustment holes, 7, support arm, 8, pedal, 9, extension bar, 10, length-adjustment holes.
Embodiment
In the following, will be explained in the embodiment of the utility model, the example is shown in the accompanying drawings and the description below.Although will
The utility model is described with reference to exemplary embodiment, it is to be understood that the description does not really want the utility model to be limited to this to show
