Description

A kind of simple type Folding Bicycle

Technical field

The utility model relates to a kind of vehicle, particularly a kind of have flexible and convenient to use, carry light labour-saving simple type Folding Bicycle.

Background technology

The kind of popular in the market Folding Bicycle is many, and folding mode also has a variety of, and their folding common purposes are the volumes that dwindle bicycle, are convenient to carry and collect keeping.Though because this class Folding Bicycle has dwindled volume effectively under folded state, but lost the function of normal walking on the ground mostly, particularly be not suitable for riding but need the occasion of the longer distance of walking at some, though existing Folding Bicycle can fold the back and carry under the situation of having dwindled volume, but must finish or need the user to carry with mode portable or pickaback, not only require great effort but also not too convenient, sometimes even become the burden of trip.For example in tourism way, the passenger generally needs under the situation with some luggage and articles more or less, if also need portable or bicycle pickaback, obviously is inconvenient and non-remunerative.So existing Folding Bicycle considers still to owe desirable, the necessary improvement from practicality and economy angle.

Summary of the invention

The purpose of this utility model is to solve necessary portable or weak point pickaback when existing Folding Bicycle is existing to be carried, provide a kind of neither need after folding portable or pickaback, can fill the post of Hand pulling vehicle again, a small amount of luggage is carried in assistance, helps the simple type Folding Bicycle of easily going on a journey and being convenient for carrying.

Simple type Folding Bicycle main body of the present utility model includes vehicle frame, be arranged on the vehicle frame front end, on the preceding mobile jib of handlebar and front-fork, be arranged on the vehicle frame rear end, on the back seat bar of saddle, rear wheel fork and rear wheel fork regulating mechanism, be characterised in that: described vehicle frame by mutual plug-in mounting link to each other, on constitute with the leading portion and the back segment of spring pin, back segment is provided with a collapsible cardan wheel; Described handlebar is by the left side handlebar and the fixed type right side handlebar of deviation constitute downwards; Described rear wheel fork regulating mechanism is made of seat pipe, seat pipe locating bush and strut bar, described seat pipe is provided with some spacing holes, the bottom of seat pipe links to each other with the end fixed vertical of vehicle frame back segment, and the upper end of rear wheel fork be hinged and connected, rear wheel fork can be rotated down around the bottom of seat pipe, be provided with the back seat bar that is used to install saddle in the axle center hole of seat pipe upper end, described seat pipe locating bush suit is provided with on the present pipe, be provided with the limitation locking bolt, its side is other to link to each other with the end assembling of described strut bar, and the other end of strut bar links to each other with the rear wheel fork assembling.During work, described rear wheel fork regulating mechanism is provided with the position adjustments rear wheel fork of the spacing hole on the present pipe and the angle between vehicle frame by the limitation locking bolt on the control seat pipe locating bush, when the limitation locking bolt is provided with on the present pipe in bottom the spacing hole, rear wheel fork be defined to the perpendicular position of vehicle frame on and contour with front-fork.

When folding, unclamp described limitation locking bolt earlier, move seat pipe location and be set to nethermost spacing hole, make rear wheel fork with vertical with vehicle frame and contour with front-fork; Rotate the angle of regulating rear wheel fork, make plane, rear wheel place all perpendicular with vehicle frame; The trip spring pin will shrink in the back segment in the leading portion again, and puts down the collapsible cardan wheel on the vehicle frame back segment; Last folded bicycle handle, handlebar downward deviation in left side is affixed by on the preceding mobile jib, fixed type right side handlebar is stretched in the draw-in groove that places under the saddle, so constitute interconnection lever that band down filled the post of by the back segment after contracting in the leading portion, go up band is made of pull bar fixed type right side handlebar hand buggy.Wherein, described collapsible cardan wheel has to put down when bicycle is parked under riding condition to be made feet, plays stable vehicle body, under the bicycle folding state,, and use as the wheel flutter of car as the front and back wheel of hand barrow or hand buggy supplemental support to interconnection lever.

So, under folded state, front-fork is mutually contour with rear wheel fork, before, plane, rear wheel place and vehicle frame are perpendicular, leading portion on the vehicle frame is inserted in the back segment, collapsible cardan wheel leaves the folding position, and vertically be positioned at below the vehicle frame back segment, constitute the supplemental support of interconnection lever, the downward deviation of left side handlebar in the handlebar is affixed by on the preceding mobile jib, fixed type right side handlebar is stretched in the draw-in groove that places under the saddle, fill the post of pull bar, so constitute band interconnection lever down, last band pull bar, the bottom is supported by front and back wheel and collapsible cardan wheel and is turned to, the hand barrow or the hand buggy of displacement.

Based on the utility model simple type Folding Bicycle of above-mentioned design, because vehicle frame is set to two-period form that the leading portion that linked to each other by mutual plug-in mounting and back segment constitute, leading portion inserts back segment and constitutes the interconnection lever of being convenient to place luggage, object when being convenient to folding; Manage the position that locating bush upper limit lock(ing) bolt is provided with the spacing hole on the present pipe by the seat of regulating in the rear wheel fork regulating mechanism, wheel fork is contour before and after making, and guarantees interconnection lever place horizontality; By the rotation rear wheel fork, make plane, rear wheel place and vehicle frame perpendicular; And by handlebar spacing method of stretching in the draw-in groove that places under the seat cushion in fixed type right side is constituted spacing failure-free fixed type pull bar; Simultaneously, because the vehicle frame back segment is provided with collapsible cardan wheel, be convenient to bicycle and when riding condition is parked, make feet, play stable vehicle body, under the bicycle folding state,, and use as the wheel flutter of car as the front and back wheel of hand barrow supplemental support to interconnection lever.Therefore, simple type Folding Bicycle of the present utility model had both had the function of normally riding under the non-folded state, has reduced volume under folded state again, portable function, also has the light Hand pulling vehicle function under the light condition, load a small amount of luggage, normal hand under the article state is pulled a cart or the hand barrow function, efficiently solving existing Folding Bicycle needs after folding pickaback portable, carry inconvenience and become the burdensome weak point of trip, compare with existing any a Folding Bicycle, obviously have simple in structure and reasonable, folding convenient and reliable, carrying after not only being convenient to fold, but also can assist the user to carry part luggage, to go off daily and travel outdoors bringing great convenience property and flexible property, thereby have very strong practicality and valuable market application foreground.
