Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the present invention includes crossbeam 9, affixedly in the front end of crossbeam 9 be provided with that front fork tube 15, middle part are affixedly provided with inner sleeve 7, rear end is affixed is provided with a pipe 6, the line of centers of inner sleeve 7 and the vertical and intersectant centerline of crossbeam 9.In the present embodiment, seat pipe 6 is crossing with the line of centers of both crossbeams 9 and angle is 120 ° to 150 °.
Front fork tube 15 is provided with front fork 16, on the top of front fork 16, handlebar 14 is installed, bottom is provided with front-wheel 13.
The upper end plug-in mounting of present pipe 6 is connected with top and is connected with extension rod with the saddle pipe 5 of vehicle seat 4, lower end plug-in mounting, mandrel is installed the lower end of extension rod is affixed, the line of centers of mandrel and the centerline parallel of inner sleeve 7, mandrel is provided with the pinch roller 2 of solid rubber material, is provided with annular groove on the surface of pinch roller 2.In the present embodiment, the sidewall at present pipe 6 top offer axially extended notch and is provided with fastener 3, realizing saddle pipe 5 and seat pipe 6 unclamping with fastening between the two by unclamping or screwing fastener 3.
Also comprise lower end and be provided with dropout, the affixed vertical fork 11 being provided with outer sleeve 10 in upper end, dropout is provided with trailing wheel 1, is also provided with chain drum 12 at the middle part of vertical fork 11, chain drum 12 adopts the fluted disc transmission of chain and trailing wheel 1.
Outer sleeve 10 is set on inner sleeve 7, the sidewall of both inner sleeve 7 and outer sleeve 10 offers the tapped bore that many groups are radial through, threaded guide sleeve is installed the outside of one of them tapped bore of outer sleeve 10 is affixed, in this threaded guide sleeve, is provided with the pin 8 of thread rod material.In the present embodiment, the inner of pin 8 is conical by its shape, outer end is provided with the collar, the inner of conical by its shape makes pin 8 be easier to move in each group of tapped bore of both inner sleeve 7 and outer sleeve 10, and the collar rises of outer end carries out the convenience of rotary manipulation to pin 8.
Be the structural representation of bicycle deployed condition in Fig. 1, can find out: vertical fork 11 fully launches between the two with crossbeam 9 until the upper limb in the middle part of vertical fork 11 falls in the annular groove of pinch roller 2; Now operate pin 8 to screw in inner sleeve 7 radial screw bore relative with a group of both outer sleeves 10, namely achieve the relative fixing of vertical fork 11 and crossbeam 9 position between the two, the entirety namely achieving expansion Rear frame is fixed.
Fig. 2 is the structural representation of folded state, can find out: when bicycle needs folding, first needs turn pin 8 to make its inner radial screw bore departed from inner sleeve 7 sidewall; Upwards mention a pipe 6 afterwards, now front fork tube 15 and front fork 16 forwards vert, trailing wheel 1 draws close to front-wheel 13; Again turn pin 8 afterwards, makes its inner another radial screw bore screwed on inner sleeve 7 sidewall, completes the locking between inside and outside sleeve, namely complete the locking of vehicle frame at folded state.
