Description

Folding bicycle

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

Existing folded bicycle kind is many, but folding position is many, fragile.

The purpose of this utility model is: provide a kind of folding position few, folding operation is easy to folding bicycle.

The purpose of this utility model is achieved in that it comprises wheel (1), support (2), handlebar (3) and stem (31), saddle (4) and saddle pole (41), folding pedals (5), its medium-height trestle comprises front fork (21), rear wheel support (22), saddle pillar pipe (23), crossbeam (24), cant beam (25) and preceding standpipe (26), characteristics are: the preceding standpipe (26) of support and crossbeam (24), cant beam has hinge connection on (25), hinge connection at preceding standpipe (26) and cant beam (25) has locking folder and safety plug, stem (31) inserts in preceding standpipe (21) by a locking folder sign indicating number clamp fitting, and saddle pole (41) is inserted in the saddle pillar pipe (23) fixing by locking folder sign indicating number.

On the technique scheme basis, it is good to the utility model proposes a kind of locking property, easy to operate locking folder, it adopts axle to be connected by the screw mandrel termination that is connected on the fraction hinge Building A with the pole termination on being connected in the hinge Building B, but screw mandrel is in the fixed end turn of hinge Building A, thereby regulate the relative length between screw mandrel and the pole, reach the purpose of regulating hinge driving fit degree of tightness.When screw mandrel and pole close up and rely on hinged before when standpipe (26) or cant beam (24), hinge Building A, Building B driving fit, on the contrary unclamp.

For further guaranteeing safety in the driving, the utility model has also adopted safety plug, and described safety plug is made up of the hook and the bar that are fixed on the hinge base, lever pin can be gone into or dial in the hook, reaches the purpose of insurance.

In the utility model scheme, designed a kind of locking folder sign indicating number (6), form by holding screw (61), locating plate (62), camshaft (63) and handle (64), handle (64) is fixed on the camshaft (63), the camshaft (63) fixed on it is arranged on holding screw (61) successively, insert locating plate (62) thereon and revolve thereon nut (65).When handle is struck, because the effect of camshaft can be played the purpose that trace is regulated elasticity.

It is few to the utlity model has burst, and it is convenient to fold, lock, the non-damageable characteristics of burst.Describe in detail below by embodiment.

Accompanying drawing 1, folding bicycle.

Accompanying drawing 2, locking folder sign indicating number.

Embodiment: as Fig. 1, the utility model comprises wheel (1), support (2), handlebar (3) and stem (31), saddle (4) and saddle pole (4), folding pedals (5), its medium-height trestle comprises front fork (21), rear wheel support (22), saddle pillar pipe (23), crossbeam (24), cant beam (25) and preceding standpipe (26), preceding standpipe (26) and crossbeam (24) at support (2), cant beam has hinge connection on (25), by the locking folder of being made up of screw mandrel and pole with by being fixed on the safety plug that hook on the hinge base and bar are formed, bar can be sold or dial in the hook in the hinge connection of preceding standpipe (26) and cant beam (25).Stem (31) inserts in preceding standpipe (21), be lined with plastic washer in the preceding standpipe (21), fastening by locking folder sign indicating number between stem (31) and preceding standpipe (21), saddle pole (41) is inserted in the saddle pillar pipe (23) that is lined with plastic washer fixing by locking folder sign indicating number.Locking folder sign indicating number is as Fig. 2, form by holding screw (61), locating plate (62), camshaft (63) and handle (64), handle (64) is fixed on the camshaft (63), the camshaft (63) fixed on it is arranged on holding screw (61) successively, insert locating plate (62) thereon and revolve thereon nut (65).This locking folder sign indicating number is easy to use, can adjust the height of handlebar and saddle very easily.Bicycle front ﹠ rear mudguard (7) adopts the ABS plastic part, at crossbeam (24) and folding pedals (5) pedestal place one strutbeam (27) is arranged.
