Abstract

The utility model relates to a portable quickly folding bicycle which is characterized in that a saddle, a saddle tube, a rear wheel, a chain, a front wheel, a front fork, handlebar vertical stems, handlebar horizontal stems, a handlebar horizontal stem fastening quickly remover, a saddle tube fastening quickly remover, and a bicycle frame, all of which are connected. Before being folded, under the condition that the space between the front axle and the rear axle is kept unchanged, the front fork and the handlebar horizontal stem protrude forwards. The folding bicycle adopts an ingenious and rational design, not only can be ridden comfortably, but also can be conveniently and rapidly folded and unfolded safely and reliably.

Description

Portable fast folding bicycle
Technical field
The utility model belongs to technical field of bicycles, particularly relates to a kind of portable fast folding bicycle.
Background technology
At present, existing laterally folded bicycle is about to the length dimension doubling of car body, to reach the purpose of dwindling the car body physical dimension, though the lengthwise dimension of the deficiency of doing like this after to be car body folding dwindled, but the size on the width over sides of car body direction has but increased by one times, and the special-purpose folding means that existing folding bicycle all must have a folding bicycle, as bicycle frame folding unit, collapsible handlebar etc., these block construction complexity, difficulty of processing is big, cost cost height; Control step is many during folding bicycle; The bicycle folding tailheaviness is asymmetric, therefore wastes time and energy.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple and compact for structure, folding operation is efficient and convenient, need not the portable fast folding bicycle of any special-purpose member.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of portable fast folding bicycle, comprise saddle, seatpillar, rear wheel, sprocket wheel, front vehicle wheel, front fork, upright, horizontal stroke, horizontal fastening quick release, the fastening quick release of saddle pipe, vehicle frame are connected and composed, described front fork comprises fork leg and vertical tube of front fork, and described fork leg is being provided with relative vertical tube of front fork off-axis distance forward with the front vehicle wheel junction; Described handle stands in the place of connecting to ground and is provided with cambered outwards stretching apart from angle.
The utility model can also adopt following technical scheme:
The off-axis of described front fork fork leg is apart from be L=30~60mm, and described handle stands that to stretch apart from angle be α=90 °~125 °.
Described front vehicle wheel is littler than rear wheel diameter, and after folding, when front vehicle wheel and sprocket wheel were in the same plane, front vehicle wheel cylindrical and sprocket wheel cylindrical minimum spacing were more than or equal to zero.
Advantage and the good effect that the utlity model has are: the utility model has been broken the traditional design theory of folding bicycle, before employing is folding, front fork, the upright structure that leans out forward, before maintenance, under the hind axle spacing unmodified situation, shortened the size of vehicle frame, front vehicle wheel when having reached folding, turn round after 180 ° upright, the length dimension of car body shortens, do not have any special-purpose member, the cost cost is low, after the utility model is folding, body gravity is stable, operation easily, fast, alleviated folding operation person's psychological burden, made the range of use of folding bicycle will obtain a bigger expansion.Especially be fit to wage-earners, need often to go up the purposes of portable downstairs.

Among the figure: 1-saddle, 2-seatpillar, 3-clothes hanger, mud plate behind the 4-, 5-rear wheel, 6-sprocket wheel, the 7-front vehicle wheel, the 8-front fender, the 9-front fork, the 9-1-vertical tube of front fork, 9-2-pitches leg, and 10-is upright, 11-is horizontal, and 12-is horizontal fastening quick release, 13-vehicle frame, 14-handle, the fastening quick release of 15-saddle pipe.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, the utility model comprise saddle 1, seatpillar 2, clothes hanger 3, back mud plate 4, rear wheel 5, sprocket wheel 6, front vehicle wheel 7, front fender 8, front fork 9, upright 10, horizontal stroke 11, parts such as horizontal fastening quick release 12, vehicle frame 13, handle 14, the fastening quick release 15 of saddle pipe are connected and composed, described front fork 9 comprises fork leg 9-2 and vertical tube of front fork 9-1, and described fork leg 9-2 is being provided with relative vertical tube of front fork 9-1 off-axis forward apart from L with front vehicle wheel 7 junctions; Described handle upright 10 is being provided with cambered outwards stretching apart from angle α with vehicle frame 13 junctions.That is: before folding, front fork 9, lean out upright 10 forward, keeping having shortened the size of vehicle frame 13 under the front and rear wheel distance between shafts unmodified situation, front vehicle wheel 7 when folding, turn round after 180 ° standing 10, the length dimension of car body shortens, and folding operation is efficient and convenient.
See also Fig. 3, Fig. 4, Fig. 5, Fig. 6, in order to make front fork 9, suitable upright 10 length that lean out forward, the off-axis of the fork leg 9-2 of described front fork 9 is apart from being L=30~60mm, and promptly the distance of front-wheel centre distance vertical tube of front fork 9-1 desaxe is L=30~60mm; Described handle upright 10 stretches apart from angle α=90 °~and 125 °.
Front vehicle wheel 7 is littler than rear wheel 5 diameters, folding after, when front vehicle wheel 7 and sprocket wheel 6 were in the same plane, the cylindrical minimum spacing of the cylindrical of front vehicle wheel 7 and sprocket wheel 6 was more than or equal to zero.Do not increase the size on the width over sides of car body direction when making the utility model folding, structure is compact more, and the modern design uniqueness is so that the utlity model has the bigger market competitiveness.
Method of operation of the present utility model: folding operation: the first step is unclamped the fastening quick release 15 of saddle pipe, and saddle 1 is dropped down onto the bottom; Second step was adopted front vehicle wheel 7 method of Rotate 180 ° backward, reached the purpose that shortens length over ends of body; The 3rd step unclamped horizontal fastening quick release 12, and upset is horizontal 11 downwards.Portable carrying handle 14 can carry-on portable.
Launch operation: the first step will be dug normal riding condition to horizontal stroke 11, press horizontal fastening quick release 12; Second step was adopted front vehicle wheel 7 Rotate 180 ° forward; The 3rd step was promoted to the height of normally riding with saddle 1 and seatpillar 2, pressed the fastening quick release 15 of lower saddle pipe, both can normally ride.
The utility model has adopted a kind of ingenious rational design concept, and it is comfortable not only to ride, and folding convenient is quick, safe and reliable when opening, do not have any special-purpose member, adopt, reached the purpose that shortens length over ends of body equally front vehicle wheel 7 structure of Rotate 180 ° backward.Adopt this foldable structure, body gravity is stable, and operation easily, fast.Alleviated folding operation person's psychological burden, made the range of use of folding bicycle will obtain a bigger expansion.The utility model is simple in structure, and the cost cost is low, and the modern design uniqueness, and is convenient to use, especially is fit to wage-earners, needs often to go up the purposes of portable downstairs, has the bigger market competitiveness.
