Perforation on plate is simultaneously connected with the nut.
The support spring is set on the screw rod, and the fixed plate and movable plate pass through the rotatable company of hinged shaft
It connects.
The upper end of the adjusting bolt is provided with anticreep pin rod.
The bottom plate includes spaced lower plate and upper plate, and the nut of the adjusting bolt is arranged at upper bottom
Plate upper surface, the support spring are arranged in the lower surface of lower plate and are set on the screw rod.
The lower plate and upper plate be two make-ups and both sides analysis be formed with the U-shaped board on wing side.
The backboard includes the arc-shaped elastic plate of bottom, the support straight panel being integrally formed with arc-shaped elastic plate, Yi Jigu
Fixed be arranged is provided with bed course on the wide plate for supporting straight panel end, the wide plate.
It is provided with massage convex on the bed course.
A kind of bicycle, including saddle are fixedly installed the backrest of the angle adjustable on the saddle, described
Bottom plate is welded to connect or is threadedly coupled with the saddle.
The bicycle is shared bicycle or shared electric bicycle.
Compared with prior art, the utility model has the beneficial effects that：
Hinge structure is introduced into back bracket so that backboard is being adjusted by the back bracket of the utility model by hinged shaft
The limit lower angle for saving bolt is adjustable, substantially increases the applicability of crowd, meanwhile, rotating function is introduced by Hinge mechanism,
The high bearing of stability is strong, and by the setting of corresponding aperture, realizes the adjusting of larger angle range.And the change of angle,
Back bracket can adjust at a distance from saddle, improved the adaptive faculty of different building shape crowd.
Description of the drawings
Fig. 1 show the oblique view of structural diagram of the back bracket of the angle adjustable of the utility model.
Fig. 2 show the overlooking structure diagram of the back bracket of the angle adjustable of the utility model.
Fig. 3 show the side structure schematic view of the back bracket of the angle adjustable of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown, the back bracket of the angle adjustable of the utility model, including bottom plate 1, it fixes and connects with the bottom plate
The fixed plate 2 connect, the movable plate 3 hinged with the fixed plate, and be fixedly connected or be integrally formed with the movable plate
Backboard 4, adjusting bolt 5 is provided between the movable plate and bottom plate, while being provided between the movable plate and bottom plate
Support spring 6.
Specifically, the fixed plate 2 and movable plate 3 is rotatably connected by hinged shaft, it is fixed on the bottom plate to set
It is equipped with nut, the screw rod perforation across movable plate and on bottom plate from bottom to top of the adjusting bolt is simultaneously matched with the nut
