Abstract

The utility model relates to a split type multifunctional bicycle which comprises a front fork component with a bicycle handle and a front wheel, a bicycle frame component with a saddle seat and a rear wheel, and a chain wheel driving component, wherein a front saddle seat is arranged on the upper end of a vertical pipe of the front fork component, a front pedal is arranged on a front shaft on the lower end of a fork pipe, the periphery of the vertical pipe is fixedly connected with an upper supporting plate and a lower supporting plate, the upper end and the lower end in a front pipe of the bicycle frame component are assembled with bearings, and the bicycle frame component and the front fork component are hinged into a whole by an upper supporting lock shaft and a lower supporting lock shaft on the upper supporting plate and the lower supporting plate. The split type multifunctional bicycle can be used as a common bicycle to run instead of walking as well as a body-building recreational apparatus which integrates body building and recreation into a whole, and has the advantages of simple structure, convenient disassembly and assembly and safe and reliable use.

Description

The multifunctional split-type bicycle

The utility model relates to a kind of bicycle, but be a kind ofly both can make the instrument of travelling of riding instead of walk, the wheelbarrow of entertainment body-building apparatus and the multifunction bicycle of tricycle front are done in the fork split.

At present, both at home and abroad bicycle have varied, no matter ordinary bicycle, or mountain bike, racing car, its function is just ridden instead of walk and is travelled.Along with the raising people of people's living standard to body building, the demand of health and fitness facilities is more and more, the wheelbarrow of existing band pedal and saddle on the market.But front fork parts such as existing ordinary bicycle, mountain bike are together with the front-wheel on it, all can not with the frame part split, therefore its asellate and pedal in vertical tube of front fork upper end can't ride as wheelbarrow.

The purpose of this utility model provides a kind of multifunctional split-type bicycle, and it can be ridden instead of walk as ordinary bicycle and travel, and can integrate body-building recreation as a kind of body-building recreation apparatus again, and it is simple in structure, decomposition, easy to assembly, safe and reliable.

The purpose of this utility model is achieved in that this bicycle comprises the front fork parts that have handlebar and front-wheel, the frame part that has saddle and trailing wheel, chain wheel drive parts, wherein front saddle is equipped with in the standpipe of front fork parts upper end, preceding pedal is housed on the front axle of breeches pipe lower end, the standpipe periphery is connected with upper and lower back plate, upper and lower end is assembled with bearing in the preceding pipe of frame part, by the upper and lower supporting shaft on the upper and lower back plate frame part and front fork parts is hinged to one.

Since the standpipe periphery of front fork parts be connected with the tape spool hole on, lower support plate, axis hole internal fixation in lower support plate has the lower support bearing pin, movable upper support bearing pin is arranged in the axis hole of the upper support utmost point, so can be by last, on before lower support bearing pin and the frame part in the pipe, lower bearing, front fork parts and vehicle frame are hinged to one, making it both to can be used as ordinary bicycle rides, again can be with its split, the upper support bearing pin is pulled up in upper support pole axis hole and head bearing hole, make the front fork parts and the frame part split of bicycle, utilize the saddle of front fork parts standpipe upper end, with the stretcher on the front axle, can be used as wheelbarrow and ride, become a kind of health and fitness facilities, both can take exercises, and can increase enjoyment by bike again.This bassinet structure is simple, and except that link, other parts all can be by existing bicycle assembly parts, and therefore, this car assembling, decomposition are conveniently.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.

Fig. 2 is that this reality is made the local structure for amplifying scheme drawing of novel link.

Fig. 3 is the utility model front fork block construction scheme drawing.

Fig. 4 is the lateral plan of Fig. 3.

Describe concrete structure of the present utility model and condition of service in detail according to Fig. 1-4.This bicycle comprises the front fork parts that have front-wheel 1, front fork 3, preceding brake 4, handlebar 5, has vehicle frame 9, rear cradling 10, back brake 11, shelf 12, flywheel 13, the frame part of trailing wheel 14 and the drive element of being made up of pedal 15, sprocket wheel 16.Pedal 2 before on the front axle of saddle 6, breeches pipe lower end is equipped with in front fork parts neutral tube 23 upper ends, being equipped with.Be connected with the upper bearing plate 7 and the lower support plate 8 in tape spool hole in standpipe 23 peripheries, axis hole internal fixation in lower support plate 8 has lower support bearing pin 22, movable upper support pin 17 is arranged in the axis hole of upper bearing plate 7, in the preceding pipe 20 of frame part bearing spacer 19 is arranged, its two ends are fixed with head bearing 18, lower bearing 21 respectively.

When using as ordinary bicycle, all the other each common components are the same with the structure of ordinary bicycle, utilize the upper and lower bearings 18,21 in the pipe 20 before the upper and lower supporting

shaft

17,22 of vertical tube of front fork 23 upper and lower back plates and the vehicle frame, it is promptly rideable that front fork parts and frame part are hinged to one.When using as the body-building recreation apparatus, upper support bearing pin 17 can be pulled up, the front fork parts can separate with frame part, the standpipe 23 of handlebar 5 transverse tubes along the front fork parts circumferentially rotated, make it with front-wheel 1 in same plane, utilize saddle 6 and preceding pedal 2 just to can be used as wheelbarrow and ride, reach the purpose of taking exercises balance and amusement.The also available tricycle front of frame part is used for transportation etc.

Claims

1, a kind of multifunctional split-type bicycle, comprise the front fork parts that have handlebar and front-wheel, the frame part that has saddle and trailing wheel, chain wheel drive parts, front saddle is equipped with in the standpipe upper end that it is characterized in that the front fork parts, preceding pedal is housed on the front axle of breeches pipe lower end, the standpipe periphery is connected with upper and lower back plate, upper and lower end is assembled with bearing in the preceding pipe of frame part, by the upper and lower supporting shaft on the upper and lower back plate frame part and front fork parts is hinged to one.
