Abstract

The utility model provides a single person and multi-person dual-purpose bicycle. The front fork of the bicycle is decomposed into an upper section and a lower section, wherein the upper section is front fork shaft lever and the lower section is front fork bayonet shaft sleeve. A rear wheel bayonet shaft sleeve is arranged above the rear wheel of the bicycle. The front fork shaft lever dynamically cooperates with the front fork bayonet shaft sleeve and the rear wheel bayonet shaft sleeve. Normally, the bicycle is for single person use, the front fork shaft lever is tightly clamped into the front fork bayonet shaft sleeve; when the bicycle is for two-person use, the front fork bayonet shaft sleeve of the back single-person bicycle together with the front wheel are clamped tightly with the shaft lever at the lower crook of the front single-person bicycle; the front fork shaft lever is clamped into the bayonet shaft sleeve above the rear wheel of the front single-person bicycle. The bicycle is for single-person use normally can be assembled for two-person and even multi-person use when needed, so as to increase the pleasure of life. Besides, the bicycle has the advantages of quick assembling and disassembling, flexible operation and high utilization factor.

Description

A kind of many people of list dual-purpose bicycle

Technical field

The utility model belongs to light running vehicle, is specifically related to a kind of many people of list dual-purpose bicycle, can drive separately for a people, also can drive simultaneously for double.

Background technology

Bicycle is widely used as a kind of light vehicle of riding instead of walk, and bicycle of all kinds emerges in an endless stream, and single bicycle is arranged, and also also has tandem bicycle.At present, the tandem bicycle style is a lot, but all is stationary structure.Tandem bicycle be people at a kind of amusement and recreation walking-replacing tool of liking Holiday, effective storage life is limited.If bought a fixed type tandem bicycle, idle and space storage problem when long is just arranged, and for this reason, the market demand is a kind of makes walking-replacing tool for single bicycle at ordinary times, leisure can be assembled into the product that tandem bicycle sightseeing is played during Holiday, yet there are no the report of this series products.

Summary of the invention

The purpose of this utility model provides a kind of many people of list dual-purpose bicycle, can drive separately for a people at ordinary times, by driving simultaneously for double or many people after the assembling.

A kind of many people of list dual-purpose bicycle, it is characterized in that: the front fork of bicycle is decomposed into two joints up and down, last joint is the front fork axostylus axostyle, following joint is a front fork bayonet socket axle sleeve, there is a trailing wheel bayonet socket axle sleeve rear wheel top of vehicle body, and front fork axostylus axostyle and front fork bayonet socket axle sleeve and trailing wheel bayonet socket shaft room are the plug-in type running-fit.

Aforesaid a kind of many people of list dual-purpose bicycle, it is characterized in that: there is a vehicle body axostylus axostyle crook under the vehicle body, the front fork axostylus axostyle is identical with the vehicle body shaft diameter, front fork bayonet socket axle sleeve is identical with the internal diameter of trailing wheel bayonet socket axle sleeve, and the diameter of front fork axostylus axostyle, vehicle body axostylus axostyle and front fork bayonet socket axle sleeve, trailing wheel bayonet socket sleeve diameter are identical.

Many people of list dual-purpose bicycle of the present utility model, when being single bicycle at ordinary times, the front fork axostylus axostyle is inserted in the front fork bayonet socket axle sleeve and with bayonet socket switch chucking; When using as tandem bicycle, place before and after two single bicycles, the bayonet socket switch opens of front fork bayonet socket axle sleeve of a single bicycle of back will be intended being contained in, throw off with its front fork axostylus axostyle, front fork bayonet socket axle sleeve is overlapped together with front vehicle wheel on the vehicle body axostylus axostyle of crook under the vehicle body of a single bicycle in front, and with the placement of bayonet socket switch chucking, the front fork axostylus axostyle is inserted on the trailing wheel bayonet socket axle sleeve of vehicle body rear wheel top of the single bicycle in front, and bayonet socket switch chucking got final product, its great advantage is that dismounting is simple and efficient, in tens of seconds time, singlely empty-handedly can become two single bicycles with two tandem bicycles of single bicycles assembling or with a tandem bicycle dismounting, very flexible.Each single bicycle structure is identical, can make tandem bicycle and use, and also can use by many person bicycles, puts sequence limit before and after not having.

The beneficial effects of the utility model are: a kind of many people of the list dual-purpose bicycle that uses the utility model to provide, can make single bicycle at ordinary times and drive use, can be assembled into tandem bicycle when needing and drive, even can be assembled into many person bicycles and drive, increase delight of life.And dismounting is quick, and is easy to operate, the degree of utilization height.

Description of drawings

A kind of many people of list dual-purpose bicycle embodiment bicycle decomposition texture scheme drawing that Fig. 1 provides for the utility model.

Fig. 2 is the single bicycle structure scheme drawing of the utility model embodiment.

Fig. 3 is the utility model embodiment tandem bicycle structural representation.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Illustration among Fig. 1～Fig. 3: 1.1,2.1-front fork axostylus axostyle, 1.2,2.2-front fork bayonet socket axle sleeve, 1.3,2.3-front vehicle wheel, 1.4,2.4-rear wheel, 1.5,2.5-vehicle body, 1.6,2.6-vehicle body axostylus axostyle, 1.7,2.7-trailing wheel bayonet socket axle sleeve.

A kind of many people of the list dual-purpose bicycle embodiment bicycle structural representation that provides referring to the utility model at Fig. 1, it is characterized in that: the front fork of single bicycle is decomposed into two joints up and down, last joint is a front fork axostylus axostyle 1.1, following joint is a front fork bayonet socket axle sleeve 1.2, there is a vehicle body axostylus axostyle 1.6 1.5 times crooks of vehicle body, there is a trailing wheel bayonet socket axle sleeve 1.7 rear wheel 1.4 tops of vehicle body, when being single bicycle at ordinary times, front fork axostylus axostyle 1.1 is inserted in the front fork bayonet socket axle sleeve 1.2 and with bayonet socket switch chucking, sees Fig. 2 for details.When using as tandem bicycle, place before and after two single bicycles, with intend being contained in the back a single bicycle front fork bayonet socket axle sleeve 2.2 the bayonet socket switch opens, throw off with its front fork axostylus axostyle 2.1, front fork axostylus axostyle 2.1 is separated placement, and it is located, front fork axostylus axostyle 2.1 is inserted on the trailing wheel bayonet socket axle sleeve 1.7 of vehicle body rear wheel 1.4 tops of the single bicycle in front and and finishes, see Fig. 3 for details the i.e. assembling of bayonet socket switch chucking.Its great advantage is that dismounting is simple and efficient, in tens of seconds time, singlely empty-handedly can become two single bicycles with two tandem bicycles of single bicycles assembling or with a tandem bicycle dismounting, and is very flexible.
