Description

A kind of folded bicycle

The utility model relates to the folding vehicle of a kind of energy.

Folded bicycle in the past is owing to the restriction of folding mode, and the stability during its use, reliable, folding comfort feature and the variety of variation all are restricted.

The purpose of this utility model is: a kind of folding convenient is provided, changes various new type foldable car.

The utility model is achieved in that a kind of folded bicycle, and it comprises: wheel (1), supporting part (2), direction control part (3), vehicle frame (4) is characterized in that; On vehicle frame (4), has a folding spider (5) at least; In three bars of frame (5), sliding bar (6) and bar (7) one end bolts; Sliding bar (6) other end embeds and is positioned among the groove of the bar (8) with direction recess, and bar (6) can slide along groove; Bar (8) and bar (7) other end bolt; Place, running condition location at the bar (6) of bar (8) is provided with positioning clamping pin (18).Because three point of connection of spider (5) all adopt the sliding block joint mode that has adopted slide bar to locate between mobilizable connection mode, particularly bar (6) and the bar (8) in groove; Therefore, greatly facilitate the folding of car.For cliding friction is effectively reduced, can load onto 1-2 pulley on the guide head of bar (6); Its width is greater than the A/F of groove; Must pack into from the port of bar (8) during installation, therefore, after car load installed, bar (a 6) top sheave will not skid off in groove, but can successfully slide at direction recess.Under the running condition of car, set the position bayonet lock at bar (6) the guide head place of bar (8); Pulley on bar (6) head is positioned; Guarantee the stability when car uses.
