Description

Four folding bicycle for tourist

The utility model belongs to life transport field, provides that a kind of folding volume is little, overall weight light, it is convenient rapid to fold, open, and is convenient to the life walking-replacing tool of going out, travelling and carrying.

At present, portable bicycle has over one hundred kind, but integrates, and they have five kinds to make the portable mode of bicycle, that is:

1, collapsible .. makes front and rear wheel be folded to together product bicycle as having at present along the vehicle frame axis.

2, reassembling type .. not the time spent split into parts and be easy to carry, ride the time spent to assemble.

3, link-type .. vehicle frame crank connecting link get up, not the time spent together collapsible.

4, telescopic .. roof beam structure is that sleeve-type can stretch

5, box .. rides time spent wheel, pedal, handlebar and pulls out in case, and the time spent does not send back to.

Above variety of way all can dwindle bicycle or deposit in the case, but still exists volume, weight to dislike big, problems such as demolition, installation are time-consuming, effort, is difficult to merchandizing.

The purpose of this utility model is design and disclose a kind of four folding bicycle for tourist, and the bicycle folding volume is reduced, and overall weight alleviates, and is convenient to fold carry and open and rides usefulness.

Implement measure of the present utility model, structure is:

It adopts little camber handlebar (calling handlebar in the following text), upward assembly such as the curved only beam of formula (crossbeam) vehicle frame, 16-20 inch trundle and saddle, Li Liang, wheel disc, pedal, clothes hanger and welding thereon four folding closing at each position connect and compose, each folding title of closing, installation position, connection, parts are folding to as follows:

(1) folding crossbeam closes .. and is positioned at the crossbeam front portion, folding close sheet and the section tube section welding of crossbeam front and back down, sheet connects and lock pin with axle up and down, connects front component and crossbeam back segment part, opens lock pin front component is overlapped to reverse fold and with wheel assembly after folding along its bosom.

(2) the folding .. that closes of saddle is positioned at the top of standing beam and crossbeam junction, folds to close upper and lower and upper and lower section tube section welding of upright beam, and sheet connects also lock pin with axle up and down, and upright beam under the connection saddle is opened lock pin and can be made saddle along its forward direction reverse fold.

(3) trailing wheel folds and closes the below that .. is positioned at crossbeam, Li Liang junction, its upper and lower is found upper and lower section tube section of beam with this place and welds, upper and lower connects and lock pin with axle, connects upright beam and wheel assembly, open its lock pin can make wheel assembly along its axle down to reverse fold.

(4) handlebar is folding closes .. and is positioned on the stem, folding close upper and lower with the welding of stem upper and lower part tube section, sheet connects with axle up and down, rides the time spent lock pin, open lock pin can make handlebar along its bosom to reverse fold and buckle on the what front-wheel.

Four folding, and to close size, structures complete in can be general, its structure by last slice and pocket chew sheet under the formula (following sheet), connecting shaft, lock pin and form, folding with convenience, safety are firm.
