On tensioner angle steel and pressed to the pull bar of tensioner angle steel by stage clip, described fixed plate offers two gathering sills, described tensioner
Plate is provided with two guiding screw poles, divides in two described guiding screw poles are arranged in two described gathering sills respectively and on guiding screw pole
The nut preventing guiding screw pole from coming off in gathering sill, described pull bar Lian Jie not had to be positioned in the middle of two described gathering sills.
Optimizing, described back-up roller wheel assembly includes fan-shaped support plate, the rolling being rotationally connected with on described fan-shaped support plate
Wheel, the curved distribution in roller axle center on described fan-shaped support plate.
Further, the radian of the roller axial connecting line on described fan-shaped support plate by both sides towards tensioner roll wheel assembly side
To being gradually increased.
Optimizing, described back-up roller wheel assembly has two lay respectively at tensioner roll wheel assembly both sides and be symmetrical set.
Optimizing, described tensioner angle steel is between stage clip and fixed plate.
Optimizing, back-up roller wheel assembly is positioned at outside the annular ring that handrail is formed, and it is band-shaped that tensioner roll wheel assembly is positioned at handrail
In the annular ring become.
Compared to prior art, this utility model has the advantage that this handrail strap tensioning device, makes the work of tensioner handrail
Make simple and convenient, improve work efficiency.Compared with regulation artificially, this Stability Analysis of Structures is reliable, easy to operate, will not be because of various people
Handrail is made to be likely to be at relaxed state for reason.And use double gathering sill, simplex pull rod, pull bar is arranged in the middle of gathering sill,
Make pinch rollers stable to the pressure balance of handrail.
