Abstract

The utility model relates to a rotatable handlebar used on a bicycle, which comprises handlebars, a crossbeam and an angle controlling mechanism. The utility model is characterized in that the handlebars and the crossbeam form a T shape; the handlebars and the horizontal surface form an angle which can be regulated along with the riding attitude; the length of the handlebars can flex. The utility model has the advantages of comfortable riding and difficult fatigue and is suitable for mountain bikes, racing bicycles, etc.

Description

Rotatable handle-bar

The utility model relates to a kind of bicycle assembly parts, and it is the improvement to bicycle handle bar.

China is the bikedom of generally acknowledging, numerous people uses bicycle as walking-replacing tool.Common bicycle handle bar has three kinds: a kind of is common flat, rational in infrastructure, uses comfortablely, but does not use power when acceleration; Another kind is a goat's horn formula handlebar, and it belongs to racing car type special vehicle handle, uses uncomfortable usually; The third is " in-line " mountain bike handlebar, and the shortcoming of this handlebar is: the people is when riding, and arm is in uncomfortable position, and the long-distance muscle of riding is very easily tired.More than three kinds of handlebar position angles all fix.

The purpose of this utility model provide a kind of rotatable angle with adapt to the handlebar of handle attitude change, reach ride comfortable, laborsaving, tireless purpose.

The purpose of this utility model is achieved in that it comprises handlebar crossbeam, handgrip, and its main points are handlebar crossbeams, and portion is provided with the handgrip angle control mechanism, and the handgrip of handlebar beam-end becomes T-shaped with crossbeam.

Said have an angle control mechanism, is contained in the housing of standpipe upper end before the bicycle, on the axle pair of bearings and a position limited gear is housed therein, and outside has a positive stop key that matches with gear, and positive stop key is contained on the small rack, and afterbody has the spring support.

Said axis and handlebar crossbeam are connected and are integral, or make one; Used bearing can be and rolls or slide.

There is telescopic pipe said handle pipe inside.

The utility model is owing to be provided with angle control mechanism, and the angle of handgrip and horizontal surface can be regulated according to riding posture, guarantees that arm is comfortable; Because there is telescopic pipe handle pipe inside, and handgrip becomes T-shaped with crossbeam, can extend handgrip when making long-distance riding and forearm is placed on it, and prevented premature fatigue.

Details of the present utility model is provided by the following drawings and embodiment:

Fig. 1 is a general illustration of the present utility model.

Fig. 2 is a kind of structural representation of the utility model.

Fig. 3 is a position limited gear fragmentary cross-sectional view among Fig. 2.

Fig. 4-6 is to use constitution diagram.

Shown in Fig. 1-3, the utility model is made up of crossbeam 3, handgrip 2, angle control mechanism 4.

3 one-tenth T-shaped of handgrip 2 and crossbeam are with extension pipe 8, pipe cap 1 in the handgrip 2.

Said angle control mechanism 4 comprises the housing 13 that is contained in the preceding riser upper of bicycle, and axis 15 is contained in the gear 14 on the axis 15 and is contained in housing 13 exterior positive stop keys 5 and forms.Axis 15 is installed in the housing 13 by pair of bearings 11, and the two ends of axis 15 are respectively charged in the crossbeam 3, and fastening with screw 9.12 and 10 is the linings that are fastened on the axis.

According to Fig. 1 and 3, positive stop key 5 is installed in the top of housing 13, and support 17 and little axle 18 are arranged, and positive stop key 5 front end wedgewises can reach spacing purpose by the gap of the 16 insertion gears of the hole on the housing.The tail end of positive stop key 5 has spring 19 to support.

Another embodiment of the present utility model can be to adopt plain bearing, and crossbeam and axis are made one, and gear is contained on the crossbeam and gets final product.

When riding, get normal condition (Fig. 4) usually, or handgrip is erected into afterburning state (Fig. 5); Long-distance riding can keep flat handgrip, and extracts extension pipe, and forearm is placed on it, and becomes relaxed state (Fig. 6), to lessen fatigue.As long as press the positive stop key afterbody during angle changing, crossbeam is freely turned to needs the position, unclamps positive stop key again, and making it snap in the between cog positioning instant can.
