Description

The bicycle folding grip structure

Technical field

The utility model is a kind of bicycle folding grip structure, major technique, purpose are: the bicycle montant is provided with holder, holder two ends group is established handlebar stem, and can make two handlebar stems launch to be a word shape for the driving use, but two handlebar stem foldings and reduced width volume when not using.

Background technology

Existing Folding Bicycle structure substantially all is set as: the vehicle body frame bendable is folding, and it is bent that the montant of handle also is set as, therefrom reduced volume.But, existing Folding Bicycle is not all being established foldable structure aspect " handlebar stem ", thin speech: prior art is that the fixedly handlebar stem of kenel (a word shape) is directly assembled in the montant upper end, and its handlebar stem is " not bent ", therefore still has bigger width volume.

The utility model content

The utility model promptly is for improving the problem that above-mentioned existing handlebar stem can not folding, make two handlebar stems launch to be a word shape for the driving use, but two handlebar stem foldings and reduced width volume when not using.

For achieving the above object, the utility model provides a kind of bicycle folding grip structure, it is provided with holder in the montant upper end, each pivot group leader bar of holder two ends, holder is provided with the quick detach bolt and locks, loosens handlebar stem, holder two ends side is provided with breach, and is ccontaining for the handlebar stem bending, thereby dwindles the width volume of two handlebar stems when not using.

In the above-mentioned bicycle folding grip structure, this holder front is provided with the telescopic chute that runs through, and quick detach bolt, with locking, loosen handlebar stem.

In the above-mentioned bicycle folding grip structure, this above and below, holder two ends is provided with the chute that correspondence runs through, thereby runs through the built-up shaft bolt and rotate the combination handlebar stem.

In the above-mentioned bicycle folding grip structure, the breach of this holder be located at holder below, form handlebar stem bent downwards.

Owing to take above technical scheme, the utlity model has following beneficial effect: bicycle montant of the present utility model is provided with holder, holder two ends group is established handlebar stem, makes two handlebar stems launch to be a word shape for the driving use, but two handlebar stem foldings and reduced width volume when not using.

The specific embodiment

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, the utility model is set as bicycle montant 10 upper ends and is provided with holder 20, each pivot group leader bar 11,12 of holder 20 two ends, holder 20 also is provided with quick detach bolt 22 and lockable, loosens handlebar stem 11,12, holder 20 two ends sides also are provided with breach 25, and can be ccontaining for handlebar stem 11,12 bendings, reach the width volume that when not using, can dwindle two handlebar stems 11,12.

See also Fig. 1, Fig. 2, Fig. 3, bicycle montant 10 upper ends are provided with the holder 20 of hollow, each group of holder 20 two ends is established handlebar stem 11,12, holder 20 is set as the front and is provided with the telescopic chute 21 that runs through and wears group quick detach bolt 22, and lockable, loosen handlebar stem 11,12, above and below, holder 20 two ends is provided with the chute 23 that correspondence runs through, and can wear group axle bolt 24 handlebar stem 11,12 pivots is combined in the holder 20, and back, holder 20 two ends is provided with breach 25 and can bends ccontaining for handlebar stem 11,12.

Pass through said structure, effect of the present utility model, effect: as Fig. 2, Fig. 3, Fig. 4, two handlebar stems 11,12 launch to be " word " shape and use for driving, 11,12 bolts 24 of two handlebar stems this moment are to holder 20 central authorities to be drawn close, quick detach bolt 22 also is lock packing holder 20 telescopic chutes 21 states, is a word shape for using and can fix two handlebar stems 11,12.Need folding handlebar stem 11,12 when not in use, as Fig. 5, shown in Figure 6, loosen quick detach bolt 22, and handlebar stem 11,12 the axle bolt 24, and can allow the axle bolt 24 of two handlebar stems 11,12 outwards slip off according to chute 23,11,12 bolt 24 terminations of two handlebar stems are during corresponding to holder 20 breach 25, breach 25 can allow 11,12 bendings of two handlebar stems ccontaining, forms to make two handlebar stems, 11,12 bending reduced width volumes; As shown in the above description, the utility model bending, the operation that launches, extremely simple and easy, quick, convenient.And, when two handlebar stems 11,12 that are Fig. 5, Fig. 6 are bending state, but reduced volume and be convenient for carrying, put, when carrying, the wheel of car body can support ground, and handlebar stem 11,12 can promote for gripping, use is extremely convenient.

In addition, according to above-mentioned technological means, this practicality newly also can implement to be the form of Fig. 5, Fig. 6, and the breach 25 of holder 20 is set as below holder 20, forms to be downward state when two handlebar stems 11,12 bend.

In sum, structure of the present utility model has splendid practicality really and promotes effect.
