During use, be fixed on two montants of ladder by left draw-in groove and right draw-in groove by anchor ear, left anchor ear and right anchor ear embrace the outdoor framework bars such as shaft tower, are then fixed firmly by ladder by Quick release.
Preferably, for making the adjustable angle between support bar and vertical ladder, the montant bottom of described vertical ladder is provided with longitudinal spacing draw-in groove, multiple L-type limited block is provided with in spacing draw-in groove, the hinged gag lever post of support bar, the end of described gag lever post is provided with groove, and the limited block in described groove and spacing draw-in groove is worked in coordination.
Described Quick release comprises nut and the body of rod, body of rod one end is provided with external screw thread, the other end is provided with handle, handle is connected with the body of rod by cam, handle can swing relative to Quick release, and by the effect of cam, the distance between the nut of handle and the Quick release other end can change, when distance diminishes, Quick release is tightened.
Preferably, be increase safety factor when ladder uses, described location anchor ear is separately positioned on the two ends up and down of vertical ladder, and ladder is by the location anchor ear that is arranged on upper/lower terminal being fixed on outdoor framework bar tightly.
Preferably, when insulating ladder directly contacts with ground or other planes, for increasing the frictional force of insulating ladder and ground, the lower end of vertical ladder is provided with antiskid glue sleeve.
Preferably, described left draw-in groove and right draw-in groove are provided with lock bolt, are simultaneously provided with anti-skidding leather packing inside left draw-in groove and right draw-in groove, and for fastening ladder and left draw-in groove, right draw-in groove, the relative motion between ladder and left draw-in groove, right draw-in groove is even stopped in minimizing.
Preferably, be equipped with keeper inside arc plate, left anchor ear and right anchor ear, described keeper is the sawtooth of evagination.
Compared with prior art, the beneficial effects of the utility model are: safe insulation ladder described in the utility model can be fixed in the structures such as shaft tower by anchor ear, safe insulation ladder can not break away, potential safety hazard can not be brought to operating personnel, another safe insulation ladder lower end is provided with antiskid glue sleeve, the frictional force between safe insulation ladder bottom and ground can be increased, reduce or stop the relative motion between safe insulation ladder and ground.
