Portable vertical bicycle

Abstract

A portable vertical bicycle comprises a two-stage telescopic rotating handle, a front fork, a front beam, a folder, a middle beam, a suspension five-way piece, a rear fork piece, a front wheel, a rearwheel and a driving mechanism. The two-stage telescopic rotating handle is formed by connecting a left handle, a right handle, an upper locking piece, a left middle connecting rod, a right middle connecting rod, a middle locking piece and a lower locking piece; the folder is connected with the front beam and the middle beam; the front beam is rotationally connected with the front axle tube of thelower locking piece; the suspension five-way piece is connected with the middle beam, rotationally connected with the rear fork piece and generates a suspension effect with the rear fork piece, a rear wheel buckle is further connected to the front end of the middle beam, a front wheel buckle is further connected to the rear fork piece, the front wheel is installed on the front fork, the rear wheel is installed on the rear fork piece, and the driving mechanism comprises a middle shaft, two cranks, a chain wheel, two pedals, a flywheel and a chain.

Description

Technical field: [0001] The present invention relates to a standing bicycle, in particular to a portable standing bicycle which can be folded small enough and is easy to carry. [0002] technical background: [0003] There are upright bikes on the market today, but no upright bikes that can fold very much. Invention content: [0004] The purpose of the present invention is to provide a portable upright bicycle which can be folded very quickly but can be folded sufficiently small. The object of the present invention is achieved in this way; a portable vertical bicycle includes a two-stage telescopic handle, a front fork, a front beam, a folder, a middle beam, a shock absorber bottom bracket, a rear fork, a front wheel, a rear wheel and The driving mechanism is characterized in that: the two-stage telescopic turning handle includes a left handle, a right handle, an upper lock, a left middle link, a right middle link, a middle lock and a lower lock. The riser pipe and the ho...

Problems solved by technology

[0005] The beneficial effects of the present invention are: the present invention uses a variety of technological means to reduce the electric welding of the vehicle body; the present invention makes the portable upright bicycle achieve the effect of small enough volume after folding through the ingenious design; the present invention adopts the latest The form of the two-stage telescopic handlebar makes the folding of the handlebar simpler and more effective; the present invention uses the front beam, the folder and the middle beam to be located at the left position, so that the folded rear wheel can be located between the front beam and the middle beam. The right side of the beam is positioned by the rear wheel buckle; the present invention uses the folded front wheel to be positioned by the front wheel buckle connected to the rear fork, so that the front wheel, the front fork and the front beam are fixed together in the folded state; The invention adopts the method of matching the shock-absorbing bottom bracket and the shock-absorbing baffle, which not only allows the rear fork to be folded forward and downward quickly with the rear wheel, but also enables the rear fork to have a shock-absorbing effect after unfolding; moreover, it adopts the The elastic joint is matched with the joint bolt and the screw hole steel ball, which solves the difficult problem that the elastic joint penetrates into the vertical hole of the polyurethane block; The through pipe is used as the folding shaft of the rear fork and has a large contact area with the horizontal through hole at the lower part of the bottom bracket, which is durable and will not loosen due to wear and tear
