Upper beam rear end and vertical beam are affixed afterwards, and the axis casing and rear upper beam are equipped with cant beam close to folder one end, it is described after on upper beam
Side wall is equipped with the engaging lug with upper beam connecting hole.
The rear axle bottom beam and rear axle camber beam are equipped with reinforcing rib at vertical beam.
The beneficial effects of the invention are as follows：
Since rear axle bottom beam rear end and rear axle camber beam rear end are affixed, the vertical beam lower end and rear axle crotch opposite side
Equipped with the engaging lug with vertical beam connecting hole, rear axle bottom beam front end and vertical beam are hinged in vertical beam connection hole, and the rear axle is curved
Beam front end extends from vertical beam two sides is hinged with damping spring, and the upper beam upper side wall is equipped with the engaging lug with upper beam connecting hole, institute
It states that damping spring front end and upper beam are hinged in upper beam connection hole, absorbs vibration by the deformation of bicycle rack as far as possible,
Improve safety and the comfort of bicycle.
Since the upper beam includes preceding upper beam and rear upper beam, the preceding upper beam is connected among rear upper beam by folder,
Upper beam rear end and vertical beam are affixed after described, and the axis casing and rear upper beam are equipped with cant beam close to folder one end, it is described afterwards on
Beam upper side wall is equipped with the engaging lug with upper beam connecting hole, and when opening folder, bicycle will be folded, and keep its light, convenient for taking
Band.
Since the rear axle bottom beam and rear axle camber beam are equipped with reinforcing rib at vertical beam, so that compact-sized, overall effect
By force, convenient for the stability of promotion bicycle.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention.
