Description

The leisure comfortable bicycle

Technical field

The utility model relates to the bicycle field, in a kind of being suitable for of more specifically saying so, the elderly, and the leisure comfortable bicycle that uses of women particularly.

Background technology

Existing bicycle is high-order vehicle seat, and when riding, because of sitting posture is too high, health must lean forward, and rides for a long time and is easy to generate fatigue, and is promptly uncomfortable, be unfavorable for health again; Also because of the sitting posture height, center of gravity is also high, if fall down easily injured.The car ladder is common car ladder, and strong point spacing is little, during parking, and a ladder of can only getting off, behind the ladder, the people can not occupy stably on vehicle seat and have a rest.

Summary of the invention

The purpose of this utility model is, prior art is improved, provide a kind of sitting posture low, can be against on the chair back and ride, during parking, can be sitting in a ladder on the vehicle seat, after propping up ladder, the people can occupy stably on vehicle seat, and is safe in utilization, convenient, indefatigability helps the leisure comfortable bicycle of bicyclist's health.

The purpose of this utility model is realized by following technical scheme: a kind of leisure comfortable bicycle, it comprises the car beam, front axle, axis, rear axle, the car fork, handlebar, vehicle seat, before, trailing wheel, chain drive mechanism, the car fork is loaded in the front-axle beam of car beam, and the upper end of car fork is connected with handlebar, pitches hinged front-wheel on the fixing front axle in bottom at car, hinged trailing wheel on the fixing rear axle in the back rest bottom of car beam, its special character is: vehicle seat places the seat pipe of the central sill of car beam, on the back rest of car beam arm-chair is set, and is fixed with by axle bed on the bottom girder that is positioned at trailing wheel the place ahead car beam, in the built-in rotating shaft of axle bed, position stopping arch plate is set, this position stopping arch plate matches with the retaining device that is provided with on the bottom girder of car beam, is fixed with handgrip in rotating shaft, is hinged with hold-down arm respectively at the two ends of rotating shaft, hinged wheel in the hold-down arm lower end is fixed with the car ladder that the baffle plate of hold-down arm is formed on axle bed.Said car ladder retaining device is by the permanent seat on the bottom girder that is fixed in the car beam, with permanent seat bonded assembly positioning hollow screw rod, is equipped with spring and steel ball is formed at the core of positioning hollow screw rod.Handlebar is telescopic handlebar, and telescopic handlebar core is loaded in the handle matches the bayonet lock of core with the spacing elongated slot of handle.

Leisure comfortable bicycle of the present utility model, because vehicle seat places the seat pipe of the central sill of car beam, on the back rest of car beam arm-chair is set, the car ladder adopts M/C, and a wheel supports, increase the structure of strong point spacing, its sitting posture is low, can be against on the chair back to ride, during parking, can be sitting in a ladder on the vehicle seat, after propping up ladder, the people can occupy stably on vehicle seat, in being suitable for, the elderly, particularly the women uses, promptly being a kind of desirable walking-replacing tool, is again a kind of recreation and body-building utensil, has safe in utilization, convenient, saddle horse is comfortable, be difficult for producing fatigue, help advantages such as bicyclist's health.
