Abstract
The utility model discloses a new type non-guideway telescopic height adjustable rotated folding bicycle, a frame connecting rod is connected with a chain wheel and a back wheel through a first connecting rod and a second connecting rod respectively; and the chain wheel is fixed on the back wheel through a third connecting rod, so the telescoping process is easy and labor saved and does not change the parts state after regulation so as not to affect the normal use of the parts. Through various folding manners, the utility model can fold the bicycle to a minimum volume state to save space. Meanwhile, the moveable connection manner of the first, second and third connecting rods can reduce the vibration and the stopper can limit the moving scope of every connecting rod.
Description
Technical field
The utility model relates to the flexible adjustable height rotation of a kind of no guide rail full-foldable bicycle.
Background technology
Bicycle is converted to recreation tool from walking-replacing tool, thereby little, the folding simple and convenient of the structure of bicycle trend volume.At present, in the various folding bicycles of Chu Xianing, folding mode mainly contains three kinds on the market: 1. common folded bicycle: certain position at bicycle is folding, and folding mode is relatively more dull, and volume after folding is still bigger; 2. rotating folding car: trailing wheel is spun upside down from the normal position, and the part that can influence the back wheels is through adjusting residing state, thereby influences the normal use of these parts; 3. guide tracked retractable vehicle: on vehicle frame, be provided with guide rail,, dwindle the volume of car by the sliding extension on guide rail.The folded bicycle of this kind mode, the precision of guide rail, hardness, fastness to rubbing require than higher, if use the low material of fastness to rubbing, occur loosening easily and influence the precision of car.If adopt the abrasion resistant special material, then can easily get rusty or be covered with dust all over because of permanent use, cause the friction force of guide rail to increase, user's more hard trouble in the flexible process of using.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and the flexible adjustable height rotation of a kind of no guide rail full-foldable bicycle is provided.
In order to achieve the above object, bicycle of the present utility model comprise front and back wheel, sprocket wheel, with foot-operated group of the sprocket wheel interlock, be connected before and after the vehicle frame connecting rod of wheels and the handlebar and the cushion rack of captiveing joint with vehicle frame connecting rod two ends respectively; Between vehicle frame connecting rod and sprocket wheel and vehicle frame connecting rod and the trailing wheel, flexibly connect by first connecting rod and second connecting rod; Captive joint by third connecting rod between sprocket wheel and the trailing wheel.
The point of connection of first connecting rod of the present utility model and vehicle frame connecting rod is arranged on the interlude of vehicle frame connecting rod; Point of connection between second connecting rod and the vehicle frame connecting rod is arranged on the cushion rack.
The variable angle scope of first connecting rod of the present utility model and vehicle frame connecting rod is: 0 °-180 °.
The junction of second connecting rod of the present utility model on cushion rack is provided with connecting rod banking stop and quick detach sleeve pipe group; Be equipped with folder on vehicle frame connecting rod and the handlebar.
Owing to adopted such scheme, the flexible translation of the utility model is the folding mode that adopts connecting rod and movable hinge, has cancelled the flexible of guide rail, so more convenient in telescopic process, laborsaving, and can not change residing state after the part adjustment, not influence the normal use of part.The utility model can be folded into car the state of volume minimum also by multiple folding mode, saves the space.Simultaneously, the flexible connection of one, two, three connecting rods of the present utility model can be played the effect of shock-absorbing, and banking stop can play and limit the action radius that each connecting rod flexibly connects.

The specific embodiment
As shown in fig. 1, the front end of vehicle frame connecting rod 17 connects handlebar 1 and front-wheel 4, captives joint with cushion rack 20 in the rear end, and interlude is provided with rotating shaft 7, and first connecting rod 8 flexibly connects by this rotating shaft and vehicle frame connecting rod.The structure of first connecting rod 8 can be single sheet, flexibly connects by rotating shaft 7 and vehicle frame connecting rod, and can be a fork-shaped as shown in Figure 2 also, the jag end is enclosed within the both sides of vehicle frame connecting rod, and the other end flexibly connects by another rotating shaft 9 and sprocket wheel 19.The both sides of sprocket wheel are provided with two groups of foot-operated groups 18, also are provided with third connecting rod 10 simultaneously, and sprocket wheel is captiveed joint with trailing wheel 12 by this connecting rod.As shown in Figure 3, third connecting rod 10 also is a fork-shaped, and the jag end is enclosed within the both sides of trailing wheel 12.Also be provided with rotating shaft 11 on the trailing wheel, an end of second connecting rod 13 flexibly connects by this rotating shaft and trailing wheel, and the other end flexibly connects by rotating shaft 15 and cushion rack 20.Junction on the cushion rack is provided with connecting rod banking stop 16, by the movable amplitude of this banking stop control second connecting rod.Also be provided with quick detach sleeve pipe group 14 on the second connecting rod.Handlebar 1 is provided with handlebar folder 2, and the front end in rotating shaft 7 on the vehicle frame connecting rod is provided with bicycle frame folding unit 6.
As shown in Figure 4, the device for quickly disassembling of quick detach sleeve pipe group 14, remove the spacing security set of secondary of connecting rod banking stop 16 again, second connecting rod 13 can free from banking stop, contract to vehicle frame stage casing make trailing wheel before pushing away before second connecting rod 10 and the trailing wheel 12 this moment, arrives the folded state of first Telescopic.
As shown in Figure 5, unclamp quick detach sleeve pipe group 14, just can be allowed to condition at second connecting rod, shorten the distance between two rotating shafts 15 and 11, realize the adjusting of height to lower slider.
As shown in Figure 6, unclamp the quick detach group of bicycle frame folding unit 6, the more spacing safety device of the secondary of opening members 6, the rotary folding device 6 then, and vehicle frame folding first half 3, front-wheel 4 rotations are turned over backward, and front and back wheel is also leaned on again together, finish the folding of the 3rd step, form the folded state of Fig. 6.
As shown in Figure 7, unclamp the quick detach group of handlebar folder 2, open the spacing safety device of secondary again, rotary folding device 2 turns over handlebar 1 rotation downwards then, and handlebar 1 and vehicle frame folding first half 3 also are close together, and realize the whole folding of bicycle.
Reverse operating then can be opened the utility model, makes it to be in operating readiness.
