Abstract
The utility model relates to multiple folded bicycle, belong to the fold mechanism in non-power-driven vehicle field, wherein said fold mechanism two punishes into three sections, and one section is unidirectional-folding mechanism, and another section is bi-directional folded mechanism, middle part connects support pulley mechanism, three sections of unifications, during normal use in line, when folding " П " font and lock, fold mechanism manifests into " П " font, complete folding time present " Z " font.As can be seen here, the utility model fold mechanism, to conceive cleverly, has made fold mechanism function compacter, estimate release after one, will be well received.
Description
Technical field
The utility model relates to multiple multifunction folding trolley, and especially a kind of Collapsible travelling cart, belongs to non-power-driven vehicle technical field.
Background technology
Bicycle is modal running vehicle.As everyone knows, existing common bicycle is primarily of being arranged on the wheel at vehicle frame two ends and being arranged on the driven by foot through chain mechanism composition of position, vehicle frame middle and lower part.Although bicycle brings many facilities to the mankind, in use also deposit some inconveniences.Such as, occupy larger space, therefore carry and deposit inconvenience.
In order to overcome this shortcoming, human hair is had to understand the bicycle that can fold.Volume when carrying and deposit is reduced owing to folding with kind of bicycle.But usually only have place's foldable structure, and purposes is single, therefore still having can improvements.
Summary of the invention
The purpose of this utility model is: for prior art exist can improvements, a kind of volume after folding is proposed less, Gu and carry and deposit multi-functional three folding connecting devices more easily, and two sections of connection fold mechanisms among being arranged on three sections, one section is unidirectional-folding mechanism, and another section is bi-directional folded mechanism, and middle part connects support pulley mechanism, three sections of unifications, connect suspension fixed mechanism outside two ends, top.It is characterized in that, three sections of unifications and outer connection are hung, and complete three folder functions, and install support, carriage.
In order to reach above object, the multi-functional three folding connecting devices of the utility model comprise midship mounting pulley gear, fundamentally solve the weak point of eighty percent discount bicycle, thus consummating function effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model embodiment deployed condition structural representation
Fig. 2 is figure meaning embodiment " Z " font folded state structural representation
Fig. 3 is Fig. 1 embodiment " ∏ " font folded state structural representation
Detailed description of the invention
Embodiment one
The multi-functional folding connecting device of the present embodiment is as shown in Figure 1: primarily of in front 2 after 13 and intermediate portion supports pulley gear 6,13,8,9,11,12 form.Linked by hinge 7-1,7-2,7-3, and locked by Manual spring stop pin 5-1,5-2,5-3, the fixing composition of external suspension 4-1,4-2.
Composition graphs 1,2,3 can be found out, foldable structure 7-1,7-2,7-3 hinge, by 5-1,5-2,5-3 lock and hinge formed in abutment unidirectional joint and single, double to activity lock articulation structure.
Composition graphs 1, middle folding support 6,13,8,10,9,11,12 be provided with mechanicalness spring rise and fall folding support pulley composition structure, act on support and slide.Composition graphs 2,3, spring lock pin 18-1,18-2,18-3 play lock in place effect.Manual spring switch 17-1,17-2,17-3 fold pole changer, add powerful after 14-1,14-2,14-3 locking.
Composition graphs 2, hinge turns to active lock 16-1,16-2,16-3 to reinforce link effect simultaneously.Manual spring pin is sat 15-1,15-2,15-3 and is played the role of positioning.
In conjunction with more than, adopt Multifunction three folding connecting device, the function of bicycle can be made to be not fully exerted, be easy to carry simultaneously, deposit, as shown in Figure 2, will fold in " Z " font, now vehicle body takes up space very little, is self-evident.When as shown in Figure 3, will in " ∏ " font foldable locking, bicycle shape " ∏ " font also mixes Folding basket, and car load forms one can loading waggon, is applicable to very much food market, supermarket shopping and outdoor travel etc., meets all kinds of crowd and use, environmental protection.
