Abstract

The utility model relates to a folding riding and pulling dual purpose bicycle, which substantially comprises a horizontal handle, a front fork lever, a top beam, a bottom beam, a rear fork lever, a seat post, a front wheel, a rear wheel, foot pedals, a two-stage gearing and a drag frame. A triangular form is used as a basic structure, the folding riding and pulling dual purpose bicycle is characterized in that a driving system is fixed on a movable bottom beam, which leads the bottom beam to rotate, the front fork lever and the rear fork lever can be turned, which leads the front wheel and the rear wheel to be parallelly folded, and the drag frame is added to achieve the deformation between the bicycle and a trailer. The folding riding and pulling dual purpose bicycle achieves that the bicycle is a simple bicycle when being unfolded and is a convenient trailer when being folded. The use is convenient, the practicability is strong, and the folding riding and pulling dual purpose bicycle is a good helper for journey.

Description

A kind of collapsible riding dragged dual-purpose bicycle
Affiliated technical field
The utility model relates to a kind of collapsible riding and drags dual-purpose bicycle.
Background technology
Existing bicycle structure mostly adopts fixedly vehicle frame of quadrangle, and existing Folding Bicycle is unsuitable for putting at home because excessive, the complex structure of tire, carrying effort, folding inconvenience, volume are big.For overcoming the problem that above-mentioned bicycle exists, the utility model proposes a kind of collapsible riding and drag dual-purpose bicycle.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and folding convenient, light collapsible riding of carrying dragged dual-purpose bicycle.
Technical scheme
The purpose of this utility model is achieved in that as shown in Figure 1 collapsible riding drags dual-purpose bicycle mainly by cross handle, front fork stem, and back timber, bottom girder, rear fork is sat bar, and front and back wheel is foot-operated, second grade transmission chain device and drag the thing frame to form.
Ride when dragging dual-purpose bicycle to fold, bottom girder and front fork stem junction can be thrown off, bottom girder will turn on the rear fork around hind axle and recline, and bottom girder front end extension is linked rear fork top.With front fork stem and rear fork revolve turn 90 degrees after, in draw close, put down the bar of taking of front fork stem and rear fork bottom simultaneously, and be connected and fixed, again front sleeve is advanced in cross handle folding back compression, sit bar and shrink the rear fork that turns back.If can tow holding back timber top when dragging away, if the thing bar that drags in front fork and the back vent can be put down when the article haul is arranged, Lee that just can let pass easily drags away then.
It is a simple bicycle that the utility model launches.Because the front-wheel 5 that adopts, trailing wheel 10 less (in allowing certain limit) is so driving system 12 adopts the secondary chain-driving, to guarantee moving velocity.
The beneficial effects of the utility model are:
The utility model is that a kind of collapsible riding simple in structure dragged dual-purpose bicycle, can be quickly and easily that car is folding, and front and back wheel is closed up the back and is realized that floor area is little, in light weight, convenient haul need not have been removed away the car after folding again, can also drag with casing class article, practical.
Description of drawings
Fig. 1 is the organigram of the utility model when being launched into bicycle.
Fig. 2 is the organigram of facing after the utility model folds.
Fig. 3 is the side-looking organigram after the utility model folds.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of collapsible riding of the utility model dragged dual-purpose bicycle, by cross handle 1, and front sleeve 2, front fork stem 3 is taken bar 4, front-wheel 5, back timber 6 is sat bar 7, back sleeve 8, rear fork 9, trailing wheel 10, bottom girder 11, driving device 12 drags thing frame 13 to form.It is characterized in that adopting driving system 12 to be fixed on the bottom girder 11, the front end of bottom girder 11 is articulated on the pivot pin of front sleeve 2 underneath hinges.Front fork stem 3 passes in front sleeve 2, can realize that front-wheel 5 turns to.Front sleeve 2 tops have hinge to be connected with back timber 6.Back timber 6 also is connected by hinge with back sleeve 8.Rear fork 9 is enclosed within the sleeve 8 of back, can realize turning to of trailing wheel 10.Sit bar 7 and be hinged on the sleeve 8 of back, and be socketed on the rear fork 9.
Ride when dragging dual-purpose bicycle to fold, the bottom girder 11 and the hitching position of front sleeve 2 are thrown off, bottom girder 11 is upwards rotated around the center shaft of trailing wheel 10, draw close in rear fork 9, and the front end of bottom girder 11 is articulated in the top of rear fork 9.Again front fork stem 3 and rear fork 9 are revolved in the same way turn 90 degrees the back in draw close, put down then and take bar 4, front fork stem 3 and rear fork 9 bottoms are connected, will make in the front fork stem 3 top retraction sleeves 2 behind cross handle 1 doubling 90 degree at last, will sit bar 7 shortenings and be folded to rear fork 9 tops and close up.
As Fig. 2, shown in Figure 3, will drag thing frame 13 to put down, can haul luggage just hold back timber 6 tops like this.
If will can be undertaken by the inverted order of folding process with the exhibition of the trailer among Fig. 3 for the bicycle among Fig. 1.
It is a simple bicycle that the utility model launches.The front-wheel 5 that the utility model adopts, trailing wheel 10 less (in allowing certain limit) is so driving system 12 has been used the secondary chain-driving, to guarantee moving velocity.
