A back clothes hanger and the frame are welded into the firm integration which is simple and sturdy; a back wheel is connected with the frame by shock absorption springs; the bicycle with a one-piece frame has the advantages of comfortable riding and strong traffic capacity. Bearings are arranged on a central axis, and the riding is enabled to be brisk and faults are eliminated; the height of a saddle is reasonable, and feet can land, which can ensure the safety; a waist supporter which is fixed to a saddle tube can enable the body to be upright, which can improve the health. The novel bicycle which combines the advantages together has the advantages of safe riding, comfortable riding, brisk riding and good body-building effect.
Description
The utility model belongs to bicycle.
In the prior art, bicycle is by running gear, guidance system, and drive system, brake system, parts such as vehicle frame, vehicle seat are formed.Power is from people's foot-operated power, and riding is saddle ride type, gets on the bus must slide one section leg advanced in years and stride seat.The back health of getting on the bus is unsettled, and pin is difficult to land.Prominent chance situation has little time to get off and will the people faces upward car and turn in riding.The posture of riding is the volt striding type of forward lean, and palm, arm, neck, crotch portion, waist be all because of unreasonable stressed and uncomfortable, the expert that is easy to get of a specified duration alleged " bicycle disease ".
Its main body of Chinese patent CN92205958.6 " four-wheeled that can be divided into two low seat bicycles " is low seat bicycle, and the deficiency of existing bicycle overcomes to some extent, but uses because of taking into account four-wheel, vehicle frame is bigger than normal, the seat is on the low side, does not have bumper, so do not realize real brisk riding.
The purpose of this utility model is to increase a kind of new model.
The utility model vehicle frame is firm, the device bumper; Be furnished with the waist holder, guarantee comfort level; Seat is high and angle is reasonable to pedal, and pin can be put on the ground during parking, and leg is stretched to such an extent that open again in the time of to pedal.Be safe, comfortable, health care, fast speed new bicycle, in order to reform existing coventional type bicycle.
This unitized frame bicycle is at vehicle seat key, that concern cyclist's safety, health and level of comfort, and handlebar through rigorous calculating, repeatedly improves and long-distance examination is ridden on the layout of axis three mutual alignment, has determined present best angle.The height of vehicle seat is scientific and reasonable, and being sitting in a last pin can land, and starts to walk like this and parking is sitting in seat and goes up and needn't get off, and also just can not fall down.Vehicle seat is furnished with little waist holder, and waist has had support, can straight and upright body when riding, and also can cooperate leg power speed to pedal by power of waist.The perpendicular bend pipe of waist holder is welded as firm integral body with seatpillar.Unitized frame is that a back clothes hanger is welded on the vehicle frame, the caliber overstriking, and promptly attractive in appearance have intensity again.Clothes hanger is assembly unit behind the ordinary bicycle, and intensity is low, and associative perception is poor.This utility model trailing wheel connects with the compressed spring type bumper with vehicle frame, similar with motorcycle structure, the back clothes hanger of reinforcement is welded as firm integral body with vehicle frame, and is succinct, solid, guarantee the structural strength and the reliability of service of this utility model, improved the traffic potential of riding comfort level and various landform.Trailing wheel is equipped with light-duty disc type lock, makes brake reliable, increases safety.The axis position of this unitized frame bicycle is equipped with ball bearing of main shaft, makes this load maximum, stressed complexity, and thoroughly taking on a new look in troublesome position, guarantees effective raising of automobile reliability.
This vehicle carriage is the single tube structure, die forming, and end welding front tube, an end reducing is in order to injecting adjustable seatpillar.The seatpillar upper end angle of axis relatively is that 60 ° of errors are positive and negative 3 ° and make waist, and several muscle groups of thigh, shank are in best work done state, and it is brisk to ride, indefatigability.Vehicle seat is clamped on the perpendicular bend pipe of waist holder, can regulate 20MM in front and back.The vehicle seat height is 750MM to 850MM, but up-down adjustment 100MM is to adapt to different height persons.The waist holder width of slimline equals vehicle seat length, highly is on the seat surface about 260MM.The perpendicular bend pipe of waist holder is identical with the seatpillar diameter, is welded to each other firmly.Being inserted with bushing pipe in the perpendicular bend pipe of waist holder, is close fit with perpendicular bend pipe, promptly inserts again not loosening easily.Property cold bending once on bend pipe mould.Aforementioned tubes is the special-purpose dielectric bonding thin-wall steel tube of bicycle.The perpendicular bend pipe curved arc place of waist holder is stressed bigger, manages in its force part lining, does not increase a lot of weight and plays humidification again.The perpendicular bend pipe of waist holder is a single tube, is welded as firm integral body with the seatpillar of single tube, and is succinct, attractive in appearance.Trailing wheel connects with the compression coil spring with vehicle frame, and this spring is about 100MM, the about 35MM of diameter, similar two bicycle swinging seat springs.Replacing the ball bearing of main shaft of axis inner integument bowl axle shelves is endoporus 17MM, the sealed bearings of outside diameter 35MM.The disc type rear-wheel brake is diverted from one use to another the prior art of light motorcycle.Handlebar is higher than the about 200MM of vehicle seat, cooperates the waist holder, can realize comfortable reliable, arm not the brisk of load ride.

Accompanying drawing 3 is a front elevation of the present utility model
Accompanying drawing 4 is a bumper constructional drawing of the present utility model
Accompanying drawing 5 is waist holder structure figure of the present utility model
As shown in the figure, the utility model is formed guidance system by handlebar (1) front-wheel (2) front fork (3), forms drive system by foot-operated (4) wheel disc (5) chain (6) trailing wheel (7) flywheel (8); Braking is front-wheel bicycle brake, the light-duty disc type lock of trailing wheel (18).Vehicle frame (9) is a single tube, mould molding.(10) for be welded as clothes hanger behind the single-piece with vehicle frame.(11) be helical spring shock absorber.(12) be the axis of interior dress ball bearing of main shaft, this axis is that 60 ° of errors are that positive and negative 3 ° of vehicle seats are gauge member with the angle of the relative Horizon in seatpillar upper end.(13) be the waist holder, (14) are the seatpillar with the perpendicular bend pipe weld together of waist holder for the perpendicular bend pipe of waist holder, (15) for perpendicular bend pipe liner reinforced pipe, (16).(17) being vehicle frame front tube reinforcement, also is the preceding connecting portions of two cars when in parallel, and back connecting portion is a rear axle, mixes to turn to lock-in tube can become the four-wheel state.
A is that 60 ° of errors are positive and negative 3 ° among the figure; B is the compression helical spring shock absorber; C is the bearing-type axis; The perpendicular bend pipe of single tube waist holder of pipe in D strengthens for the curved arc place is lined with.
This unitized frame bicycle has universal car series and student's car series, popularizes car front-wheel footpath 510MM, trailing wheel footpath 610MM, and car load is about 1600MM.Student's car front and back wheel directly is 510MM, and car load is about 1500MM.
This utility model is compared with existing bicycle to be had:
Security is good: go out and set out on a journey, safety is the first element, and riding ordinary bicycle has and suffer the body that falls Meeting has the sorrow of permanent disability. This utility model is that health does not disseat, and pin can be put new model on the ground, therefore meets Various situations can both be disposed calmly, Effective Raise walking along the street safety.
The comfort level height: riding existing bicycle all is that health is unsettled, and the arm support upper body is ridden, and does not really relax Clothes.
