Description

Folding portable bicycle

(1), technical field: the utility model is a kind of car of riding instead of walk, folding portable bicycle particularly, this car is that it can rotate 90 degree-180 degree and fold with the stretch tight car of riding instead of walk of composition such as soft seat stool, packing bag of handgrip hold-down arm, handgrip sector arm, seat stool hold-down arm, the flexible cross bar of vehicle frame, foot-operated arm lock collar, tapered end, cloth.

(2), background technology: a kind of folding bicycle of having generally acknowledged is arranged; Method for folding is that handgrip strut bar folding 180 degree are downward, and vehicle frame cross bar, brace folding 180 are spent backward, and the seat stool supports downward the contraction, can carry stair activity or put the roadlice luggage boot into, though this folding bicycle has above advantage, reach to popularize and use and place, be difficult to realize.

1, be that handgrip supports downwards and the front-wheel flat raft, again with front-wheel backward with the trailing wheel flat raft, this sample car is to have shortened, width really increases a lot.

2, the seat stool supports to stretch downwards to contact to earth and does front-wheel stable car, flexible type or pollution.

3, because the bicycle after folding is very lack of standardization, take up space during placement more.

4, this folded bicycle can only be used trundle, and the trundle bicycle pedals gets soon, and car loses time, and it is in a hurry to be not suitable for going to school.

(3), summary of the invention: provide that child, market shopping are gone to school, pick in a kind of working, a seat ship can both be carried the multi-functional car of being convenient to place of riding instead of walk by bus.

Technical measures of the present utility model are as follows:

(1) is end socket round plate of head weldering in handle stem, handgrip sector arm that lockhole and pin-and-hole are arranged of weldering in the middle of the steel plate.

(2) be to support the handgrip arm support that cross-arm two respectively is welded with lockhole and pin-and-hole at handgrip, the handgrip arm support that is welded with the lock pin sleeve pipe of packing into is put on pivot pin, again spring, locking bar are passed the arm lockhole in sleeve pipe outside the protruded tube from support to perforation, put on handle with the pile crown top as tapered end, take out pile crown because of on the elastic force effect automatic lock, need folding just the doubly-linked handle gently to be drawn, gravity decline 90 degree because of handgrip, another lockhole of arm is aimed at tapered end (snap lock work), uses with quadrat method both hands also can be done by automatic lock praising 90 degree.

(3) be that handgrip hold-down arm, a seat stool hold-down arm have a pin-and-hole, a plurality of lockholes in order to last method as required can before and after respectively turn 90 degrees folding or mobilize in front and back.

(4) be that the memorial archway seat is to be connected setting for handgrip supports with the cloudy letter of front-wheel; Be convenient to remove the locking screw pole cap, method for making is the four directions seat that is converted into screw hole with little band steel, and there is screw hole the below, top welding hold-down arm support.

(5) the outer letter of expansion link mouthful reinforcing weldering one circle steel band, the lock pin sleeve pipe is welded on the porose steel band, with spring and locking bar threading in the outer nozzle, refill doubly-linked handle control locking bar after the outlet, all there is cooresponding lockhole the front of Nei Jian and back up and down, with the doubly-linked pull-up of shaking hands, the inner core of packing into, the automatic fermium of preceding alignment of a hole tapered end stretches out as inner core, and drawing again, handle shrinks inner core, lockhole is aimed at tapered end and is locked (but just hand is from handle as long as tapered end withdraws from lockhole, another lockhole is to the potential energy automatic lock).

(6) foot-operated arm lock collar is that a triangle steel plate (the phase formula is in the handgrip sector arm) just makes axis hole into a thread hole, connect by making horizontal position welding into along weldering, steel plate is drilled with the triangle lockhole, the foot-operated studdle lock collar of packing into, and tight 1/4 another lockhole is aimed at tapered end and is locked (folding stretcher).

(7) parking foot rest, boring two cooresponding bolts hole up with a square plate is converted into double fastener mouth (double fastener mouth R signal) internal orifice folder central frame beam and wears bolt, collar extension folder folding foot rest supports stalk, steel plate left side Zheng becomes the upright folder mouth of strut bar, (there is the shaft lock hole of wearing the chord strut a folder mouthful top to supporting rod clamp in mouth during expansion, the pivot pin strut bar of riveting over can be turn 90 degrees upwards folding, launch downwards, because of all there being the folder mouth just just can advance the folder mouth up and down with supporting with a spot of power, foot rest is the turn-over spiral-lock, and car promotes strut bar forward and can not withdraw from, and is less to pusher, but gripping power is arranged, because of the folder mouth is

Overdo.

(8) the soft seat stool frame that stretches tight, with flat steel bar be converted into be drilled with the spill connecting bore after stretch tight after frame and expansion bracket put on bolt, load onto standing screw and transfer the nut baffle plate, (standing screw, nut baffle plate scheme drawing are slightly) tightens cloth cover with transferring nut, aim at the connection screw with cloth awl eye with awl, put on the connection overbolt, load nut and will go out the cap bolt again and pierce into spring bracket and fix.

(9) S. A. lock pin; Be washed into a sleeve pipe that about 15 millimeters long of step are arranged with steel plate, a joint spring, car has tapered end that the locking bar in handle hole is arranged again, and sleeve pipe is welded in hold-down arm support lockhole, vehicle frame cross bar lockhole, the foot-operated lockhole that supports, and installation method is in the existing explanation of technical measures (2).

(10) packing bag waterproof sheet is sewed with handle above, is sewed with the wagon spout of slide fastener below, and openning can be opened on the left side or the right, also can open up.

Compared with prior art: (1) preceding steamboat is few with material, cost is low, in light weight, take up space less, can reduce sewage dust fly to be stained with clothing, avoid when turning before bull wheel grazing people's tiptoe; (2) fast, the operation of self-locking folding method speed easily, easy break-down not; The folding cars of riding instead of walk such as (3) handgrip, handgrip support, seat stool, stretcher, vehicle frame cross bar are flexible, specification is little, volume is thin, is easy to carry to be convenient to deposit; (4) cloth cover soft seat stool can be cool in summer and warm in winter, can keep healthy because of moulding diseases such as prostate that a stool causes, bladder firmly; (5) the packing bag can prevent that the vehicle day solarization drenches with rain, and places baggage container and does not also pollute other article.
