Abstract

The utility model discloses a portable folding bicycle. The crossbeam of the bicycle is divided into a front and a back sections and are hinged together; the front and the back sections of the crossbeam are respectively fixed to a front and a back connection components, wherein, the end part of one connection component is provided with a connection plate; the end part of the other connection component is provided with a connection groove which is matched with the connection plate; the connection plate and the connection groove are hinged together; the lower parts of two connection components are provided with connection pins; the outer ends of the connection pins are sheathed with a compression spring. The utility model has the advantages of simple structure, is improved on the existing bicycle whose crossbeam is slightly changed, and is convenient to assemble and disassemble; the hinged connection position is safe; compared with the original bicycle, the outer size of the folded bicycle is reduced by 50-60%, which is convenient to carry and store.

Description

Portable folding bicycle

The utility model relates to a kind of portable folding bicycle.

Existing bicycle kind pattern is a lot, but all has common shortcoming, and promptly volume is bigger, and it is big to take up room, and is not easy to carry in car, ship and elevator and deposits; New bicycle is placed on outdoorly to be lost easily, has the people to lose three cars in one month, makes the people dare not buy new car, moreover along with also increasing of people day off, the chance of travelling outdoors increases, and also will cover a long distance after getting off in many places; Also have some working to leave home to have some setbacks more by bus, if can one section take electricity (vapour) car, another section will be saved many times by bike; If therefore produce portable bicycle, will bring great convenience to people.

The purpose of this utility model is to design and a kind of crossbeam is designed to two sections and the portable folding bicycle that is hinged together for overcoming existing weak point with bicycle, and easy to carry, it is little to take up room.

The utility model content, the crossbeam of bicycle are made as two sections of front and back and are articulated and connected; The front and back of crossbeam are being fixed the front and back attaching parts respectively for two sections; The end of one of them attaching parts is a connecting panel, and the end of another attaching parts is the link slot that matches with connecting panel, and both are hinged; Connecting pin is equipped with in the bottom of two attaching partss, and connecting pin outer end suit compression spring.

The utility model advantage, because the bicycle crossbeam is made as two sections and be articulated and connected, can be when extracting connecting pin with bicycle folding, the oad after folding is original 50～60%, it is little to take up room, and is easy to carry, deposits.

Below in conjunction with description of drawings the utility model embodiment, the crossbeam of bicycle is made as front and back two section 11,3, and is welded with attaching

parts

12,13 respectively, and wherein the end of rear connectors 12 is a connecting panel, and the end of preceding attaching parts 13 is a link slot; Connecting panel and link slot are hinged and nut is housed by screw 4; Connecting pin 15 is equipped with in the bottom of two attaching partss, and two attaching

partss

12 and 13 can not be relatively rotated; Be fixed with block 8 on the connecting pin 15, fixing stop block 9 on the leading portion 3 of crossbeam, connecting pin 15 passes stop block 9 and establishes handle 10 in the outer end; Suit compression spring 16 on the connecting pin 15 of 9 of block 8 and stop blocks, when using the utility model, connecting pin 15 injects in the pin-and-hole of attaching

partss

12 and 13, because the effect of compression spring, connecting pin 15 keeps normal control position, can not guarantee safety by deviating from the pin-and-hole.Use and finish, connecting pin 15 is extracted by the pin-and-hole of attaching parts 12, the leading portion 3 of handlebar 1, front-wheel and crossbeam serves as that axially the back is folding with hinged screw 4, and vehicle seat 3, pedal 5, trailing wheel 6 and shelf 7 positions are motionless; During use, handlebar 1 is set back, connecting pin 15 can use inserting again under the effect of compression spring 16 in the pin-and-hole of attaching parts 12; Install and remove easy, safe and reliable.

Claims

1, a kind of folding bicycle is characterized in that: the crossbeam of bicycle is made as two sections of front and back and is hinged together; The front and back of crossbeam are being fixed the front and back attaching parts respectively for two sections; The end of one of them attaching parts is a connecting panel, and the end of another attaching parts is the link slot that matches with connecting panel, and both are hinged; Connecting pin is equipped with in the bottom of two attaching partss, and connecting pin outer end suit compression spring.
