The specific embodiment

Below in conjunction with Figure of description and specific embodiment, the present invention is further described.

This Collapsible bicycle comprises precursor (not shown in FIG.), rear body (not shown in FIG.), front bar 8, rear bar 9 and bicycle folder 10, after forward and backward bar connects by bicycle folder, respectively at precursor, rear body, is fixedly connected with.Precursor is the parts such as common front-wheel, handle, and rear body is the common parts such as common trailing wheel and pedal flywheel, therefore at this, does not repeat; The front portion of front bar 8 is that its rear portion of radian bar of upwards protuberance is straight-bar, and the rear end of this front bar is connected with rear bar by bicycle folder.

Bicycle folder 10 comprises upper cover 1, lower cover 2, latch segment 3, adjust bar 4, spring 5 and adjust bar fastening unit 6, before, rear bar is respectively with upper, lower cover is fixedly connected with, upper cover 1 is mutually hinged with lower cover 2 laminating formation folder main bodys 12 and both one end, on, between lower cover, form cavity 121, lower cover 2 madial walls are provided with a plurality of holes 21 that wear, adjust bar 4 wears hole 21 through these and slides and be arranged in this cavity and one end is positioned at, the outside of lower cover is the outer end 41 of adjust bar, its other end is positioned at cavity, latch segment 3 is placed in cavity and is fixedly installed on adjust bar 4 by screw thread, on, lower cover inwall middle part is provided with projection 7 in correspondence with each other, on, projection 7 contacts between lower cover are connected to form inverted V-shaped ridge 7a, latch segment is provided with the groove 31 of the V font corresponding with projection 7, when V-arrangement projection is plugged in groove, on, lower cover is subject to the restriction of latch segment 3 can not be separated, spring 5 is sheathed on adjust bar 4 and elasticity connects the bottom land of projection 7 and groove 31, adjust bar fastening unit 6 connects the outer end of adjust bar 4 and the corresponding outer wall section of upper and lower cover, when the not modulated pole fastening unit constraint of adjust bar 4,3 of latch segments are separated with projection under the effect of spring 5.

On, the mutually hinged one end of lower cover is the pin jointed end 122 of folder main body 12, the other end relative with pin jointed end is the folding end 123 of folder main body, folding end 123 is that semicircle its middle part is polished part plan 123a of smooth formation, adjust bar fastening unit 6 comprises handle set 61, eccentric handle 62, set pin 63, these handle set 61 middle parts are provided with through hole 611 and a side, and to be provided with arc groove 612 its another sides be plane 613, handle set 61 is connected with the part plan 123a contact of folding end 123 by its plane 613, eccentric handle 62 is the arc bent plate adapting with folding end, its one end is the round nose 621 corresponding with arc groove on handle set and is rotationally connected with arc groove 612, this end is provided with a circular hole 621a at the lateral deviation heart near eccentric handle center, set pin 63 is placed in circular hole 621a rotationally, the side of eccentric handle round nose 621 is provided with chute 621b, and the outer end 41 of adjust bar 4 is fixedly connected with by screw thread with set pin 63 through through hole 611, chute 621b successively.

Initial condition, upper and lower cover respectively with by forward and backward bar, be connected the forward and backward body of bicycle, now, the projection of the groove of latch segment and upper and lower cover inwall is in released state, the circular hole at set pin place is in the closest approach relative with projection, rotate eccentric handle, the circular hole at set pin place moves until be rotated further eccentric handle after turning over solstics until eccentric handle is subject to the restriction of folder main body folding end and can not moves to solstics from the closest approach relative with projection, now adjust bar drives latch segment towards inverted V-shaped ridge direction, to slide in folder main body, allow groove in latch segment and upper, projection laminating on lower cover inwall, on final, lower cover is because projection can not be separated with the engagement limits of groove, now the front and rear part of bicycle middle part pipe link is fixedly connected on straight line, now, the spring being placed between groove and projection is squeezed to latch segment and projection generation thrust, set pin in eccentric handle circular hole is subject to the pulling force that latch segment passes over by adjust bar to have continuation to drive the trend of the round nose rotation of eccentric handle, and eccentric handle is now limited to be rotated further with the folding end outer wall laminating of folder main body, under this situation, eccentric handle is by locked, bicycle can normally use, oppositely pull eccentric handle, make the groove in latch segment separated with the projection on upper and lower cover inwall, now latch segment is separated with projection under the effect of spring, and upper and lower cover can be rotated around the pin jointed end of folder main body, now can realize the folding storage function of bicycle.

The projection that the present invention regulates the motion of latch segment in folder main body to lock and separate upper and lower cover inwall by eccentric handle and spring, if adopt direct pull adjust bar and the mode of several pin-and-holes by lock clasp adjust bar be set in the outer end of adjust bar and also can realize above-mentioned functions, obvious thus, other adopt the technical scheme of latch segment, spring, projection and adjust bar in the present invention all in technology enlightenment of the present invention.

The present invention by eccentric handle, regulating handle and adjust bar, control groove and upper and lower cover inwall projection be connected the folding with separated folder, simple and reliable for structure, easy to use.
