Abstract

The invention discloses a dual-damping bicycle frame which comprises a frame body; a fixed buckle plate is welded to the top of the frame body; the bottom end of the frame body is rotationally connected with a front support arm and a rear support arm by means of an outer sleeve; the upper end of the frame body is rotationally connected with a front rack and a rear rack by means of the outer sleeve; a handlebar fixing frame is welded on one side of the front frame and one side of the front support arm; a connecting column is arranged in the handlebar fixing frame; a damping spring is arranged at the top end of the connecting column; damping cushions are arranged on two sides of the lower surface of the connecting column; an inner sleeve is arranged on one side of the outer sleeve, and is connected with a front sealing plate in a buckling manner by means of a press-fit gasket; an embedded backing ring is arranged on the other side of the outer sleeve; and a rear sealing plate is arrangedon one side of the embedded backing ring. The bicycle frame is simple and reasonable in integral structure and design, small in size, convenient to carry and transport, firm and durable, and convenient to fold, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a double shock-absorbing bicycle frame. Background technique [0002] Folding bicycles belong to a category of bicycles. Generally, folding bicycles are composed of frame folding joints and riser folding joints. By folding the frame, the front and rear wheels can be folded together, which can reduce the length by about 45%. Put it in the cabin and folding bag, as well as the trunk of the car. During the folding process, no external tools are needed. The car can be folded and unfolded manually. After folding, use the seatpost as a support point to make it stand upright Stable, and the rotary folding bicycle is also a form of folding bicycle. [0003] However, there are some deficiencies in the existing rotary folding bicycle frame during use. The overall shock absorption effect of the frame is not obvious enough, which will increase the wear and tear of the frame and bring unsaf...
