The Dual-purpose cross-country bicycle capable of running on a snowfield and a public road has simple structure and can be conveniently assembled and disassembled.

Description

The dual-purpose Mountain bike of snowfield and highway

Technical field

The utility model relates to a kind of bicycle field, especially snowfield and the dual-purpose Mountain bike of highway.

Background technology

At present, the apparatus of skiing comprises: skis, sled, ski type motorbike are several, the disclosed snow bicycle of Chinese patent, publication number CN2161558Y, it is characterized in that vehicle body frame is installed on the ski, stretcher is stirred basket drive system (and accessory power system), installs on the vehicle body frame, its deficiency, it is difficult to move even one step that snow bicycle leaves snowfield, about snowfield and the dual-purpose light body bicycle of non-snowfield highway, still do not have relevant scientific and technical literature report.

The utility model content

The purpose of this utility model is according to the prior art deficiency, and a kind of dual-purpose Mountain bike that can exercise on snowfield or non-snowfield highway is provided.

The technical scheme that the invention for solving the technical problem adopted is, the dual-purpose Mountain bike of snowfield and highway comprises: preceding ski, front tyre, handlebar, vehicle seat, chain drum, stretcher, chain, transmission chain drum, rear tyre, back ski constitute, front tyre both sides on the front bearing bar are installed front support rod respectively, connect pivot shaft spare and link on preceding ski.

The dual-purpose Mountain bike of said snowfield and highway, in the rear tyre both sides respectively with the axis hole device of back support rod upper end on the rear bearing bar, the back support rod lower end is installed in and connects pivot shaft spare on the ski of back and link together.

The dual-purpose Mountain bike of said snowfield and highway is installed several and is taken off sled on rear tyre, in the middle of on the ski of back, establish a rear tyre groove.

The dual-purpose Mountain bike of said snowfield and highway, when at snowfield by bike the time, have the rear tyre of taking off snow slab, in the middle of the ski of back, if ski groove after, by people's power stretcher, drive chain drum cochain bar, rotation seam dish and rear tyre are rotated, take off on the rear tyre under the adverse effect power of snow slab and snowfield, driving bicycle slides forward fast, on the highway of non-snowfield, ski and front support rod are taken off snow slab on back ski and back support rod and the rear tyre before taking off, bicycle front tyre and rear tyre are landed, and bicycle can be in the highway fast running.

The utility model beneficial effect, the dual-purpose Mountain bike of snowfield and highway is preceding ski of front support rod lower end installation on the front bearing bar of bicycle front tyre respectively, ski after the back support rod lower end is installed one on the rear bearing bar of rear tyre, several are installed on rear tyre take off snow slab, by people's power stretcher, drive on the chain drum and stitch bar, rotation chain drum and rear tyre are rotated, take off on the rear tyre under the adverse effect power of snow slab and snowfield, promote bicycle and slide forward, on the highway of non-snowfield, ski and back ski before taking off, take off snow slab on the rear tyre, make front tyre and rear tyre landing ground, bicycle is in the highway fast running, and this is simple in structure, assembly and disassembly are convenient, are a kind of novel snowfield and highway dual-purpose bicycle.
