Abstract

The utility model relates to a manpower traffic tool, in particular to a relaxing four-wheel pedal cycle. The cycle consists of two compound horizontal jointed big camber beam bicycles. The front root parts of big camber beams of the two bicycles are fixedly connected through a front connecting bar. The upper ends on back frames of the two bicycles are fixedly connected through a back upper connecting bar. Rollers of back wheel axles of the two bicycles are fixedly connected through a back lower connecting bar. The root parts of front forks of the two bicycles are respectively provided with a rocker and the top ends of the two rockers are connected through a direction control connecting bar. The cycle extends the use functions of bicycles. The four wheels touch the ground and lead the cycle to be stable and safe no matter in a static state or a moving state. The characteristics of a lower cycle body and saving labor up and down are more suitable for the elderly to use. The function of conveniently carrying people and objects shows the characteristic of leisure application.

Description

Leisure type four-wheeled bicycle

Technical field:

The utility model relates to the manpower transportation, particularly a kind of leisure type four-wheeled bicycle.

Background technology:

Though bicycle has many good qualities as the widespread usage vehicle, but its stability is good inadequately, can not stand-alone when static, armrest is grasped balance to (front-wheel) when riding, be subjected to external force slightly, particularly front-wheel is interfered, and very easily lack of equilibrium causes car to fall the people to turn over, take under the principle condition more so the band people, be not suitable for the old man and ride.The stability of three-wheel vehicle increases than bicycle, but still has overturning hidden danger when turning on the side direction ramp, and the band people seems heavy when taking thing.

Summary of the invention:

Goal of the invention of the present utility model is in order to expand the functions of use of ordinary bicycle, and a kind of stability height, riding safety are provided, are more suitable for the leisure type four-wheeled bicycle of the elderly's use.

The technical scheme that realizes the foregoing invention purpose is: this leisure type four-wheeled bicycle is made of the horizontal conjuncted big camber beam-type bicycle of two compound types, the root position is by a front rod captive joint before the big camber beam of two cars, the upper end of two car after poppets is by back boxed rod captive joint, pass through back lower link captive joint between the two back wheels of vehicle axle rods, the fork root portion is not equipped with a rocking arm before two cars, and two rocking arm tops connect by a directional control linkage.

The leisure type four-wheeled bicycle that obtains according to this technical scheme, owing to be on existing finished product bicycle basis, to combine, so processing and fabricating is very convenient.Be still two bicycles after its partition come, so expanded the functions of use of bicycle.This car four-wheel lands, and makes full use of car body active channel width, has strengthened stabilising surface, thereby improves stability, makes it still all to guarantee steady safety when static when motion, and its vehicle body is low, the labour-saving characteristics are more suitable for the elderly's use up and down.

In addition, child seat or little goods basket can be installed,, embody the characteristics that its leisure type is used so that the band people takes thing by the connecting elements such as back upper and lower connecting rod of this car.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a directional control linkage planar view of the present utility model.

Specific embodiments:

Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.The described leisure type of this embodiment four-wheeled bicycle is made up of two the 24 big camber beam woman's bicycles 1 of type, directional control linkage 2, rocking arm 3, front rod 4, back lower link 5, montant 6, back boxed rods 7.The root position is by front rod 4 captive joints before the big camber beam of two cars 1, the upper end of two cars, 1 after poppet is by back boxed rod 7 captive joints, by back lower link 5 captive joints, the fork root portion is not equipped with rocking arm 3, two rocking arms 3 tops by directional control linkage 2 connections before two cars 1 between two cars, the 1 hind axle rod.

In this enforcement, also be fixed with montant 6 between the two ends of the two ends of back boxed rod 7 and back lower link 5, make between back boxed rod 7 and back lower link 5 and two montants 6 to constitute stable parallelogram sturcutre.Simultaneously also be convenient to install child seat or little goods basket.

Claims

1, a kind of leisure type four-wheeled bicycle, comprise laterally conjuncted big camber beam-type bicycle of two compound types, the preceding root position of big camber beam that it is characterized in that two cars is by a front rod captive joint, the upper end of two car after poppets is by back boxed rod captive joint, pass through back lower link captive joint between the two back wheels of vehicle axle rods, the fork root portion is not equipped with a rocking arm before two cars, and two rocking arm tops connect by a directional control linkage.

2, leisure type four-wheeled bicycle according to claim 1 is fixed with montant between the two ends of the two ends of boxed rod and back lower link after it is characterized in that.
