Abstract

The utility model relates to a bicycle's handle bar capable of rotating horizontally, which comprises a handle horizontal tube, a handle stand tube, a handle joint and handle core screws, etc. The handle stand tube is provided with an outer tube and a bar clasp which is tightly fixed on the handle stand pipe, the upper end of the outer tube and the handle horizontal tube are connected as integration by the handle joint and the lower end is movably fitted with the bar clasp, and the outer tube is provided with a handle bar lock. The locking plug and the lock hole on the handle stand tube are locked when riding, the lock is opened when depositing, the handle horizontal tube can drive the outer tube turning 90 DEG corresponding to the handle stand tube in order to close the lock, and the locking plug is locked with the other lock hole of the handle stand tube. The handle bar and the bicycle body are formed a parallel direction at the time in order to reduce depositing space and strengthen theft protection.

Description

Bicycle's handlebar capable of rotating horizontally

The utility model relates to a kind of bicycle handle bar, and specifically it belongs to a kind of bicycle handle bar that horizontally rotates.

Existing bicycle handle bar, by transverse tube, handle riser, joint, core screw, sneek etc. are formed, transverse tube by joint and handle riser are linked to be an integrated member, the core screw is fastened on the joint, insert in the front fork tube through the preceding hole of vehicle frame the lower end of handle riser, fasteningly just can make handlebar and front fork become integral body, turn handlebar and just can control the purpose of wheel direction thereby reach a silk screw.Yet because wheel radial is 90 ° of directions before handlebar and the car, need take bigger space, bad putting in crowded space, this has also hindered people's brains.For addressing this problem, people have thought thousand and one way, the way that had the people to propose full-foldable bicycle in 1988, being about to the handle riser reduction folds back, front and back wheel is closed up, receive folded pedal etc., its shortcoming is to install handlebar folder, pedal folder, vehicle body folder, handlebar and barre coupling etc. additional, and receiving when folding relatively wastes time and energy; After again the someone propose to be provided with on transverse tube turnover mechanism, when bicycle storing, handlebar grip is turned down 90 ° simultaneously together with sneek, its shortcoming is the mechanism's complexity of turning back, operation inconvenience, and this structure will influence in the service life of transverse tube and sneek.

The purpose of this utility model is to propose a kind of bicycle handle bar that horizontally rotates that reduces parking space, simple in structure, easy to operate, highly versatile and be added with anti-joyride device.

The utility model is to constitute like this, and it mainly by transverse tube, handle riser, joint, core screw, sneek etc. are formed, is with outer tube and clip that the band handlebar is locked on handle riser, directly be fastened on the core screw on the handle riser; Outer sleeve upper by joint with transverse tube is connected as a body; The clip bolt up makes it to be integral on handle riser, and has the lockhole that two sustained heights, spacings differ 90 ° on the handle riser; Outer tube can rotate around handle riser under transverse tube is driven; Clip works to support outer tube; Owing to have the handlebar lock on the outer tube, lockhole is arranged on the handle riser, therefore can handlebar be locked into respectively with car before wheel radial be parallel direction and be 90 ° of directions.

The block of one projection is arranged in the outer tube lower end, in the upper surface of clip one arc groove is arranged, block places in the arc groove.Block rotates in arc groove, just in time makes the handlebar lock aim at lockhole when going to two ends, therefore can play the role of positioning.

The utility model is compared with existing bicycle handle bar structure, has little, simple in structure, easy to operate, the advantage such as commonality is good, anti-theft is strong that takes up room.

Since handlebar horizontally rotate 90 ° after with car front-wheel radial parallel, so can reduce the bicycle storing space; Owing to install the handlebar lock additional, can't ride after the preceding wheel radial of handlebar and car is the parallel direction locking when parking, no key then can't make handlebar reset, so strengthened anti-theft; Owing to adopted the scheme of handlebar rotation, thus simple in structure, easy to operate, again owing to transverse tube, can adopt general part to core screw etc., so commonality is good, the standardization level height,

Below in conjunction with embodiment and accompanying drawing, further describe the utility model:

Fig. 1 is the section-drawing that can horizontally rotate handlebar;

Fig. 2 is the A-A ' section-drawing of handlebar lock;

Fig. 3 is the birds-eye view of handlebar;

Fig. 4 is B-B ' section-drawing of Fig. 1.

Wherein 1 is transverse tube, and 2 is handle riser, and 3 is joint, and 4 is the core screw, and 5 is the core nut, and 6 is packing ring, and 7 is outer tube, and 8 is clip, and 9 are the handlebar lock, and 10 is locking plug, and 11 is pressure spring, and 12 is arc groove, and 13 is block, and 14 is lockhole, and 15 is lockhole.

Embodiment:

A kind of bicycle handle bar that horizontally rotates (as Fig. 1, shown in Figure 3) by transverse tube 1, handle riser 2, joint 3, core screw 4, core nut 5, packing ring 6 etc. is formed, is with outer tube 7 and clip 8 on the handle riser 2.Core screw 4, nut 5 directly are fastened on the handle riser 2, have 2 lockholes (14,15) on the handle riser 2, be positioned at sustained height and differ 90 °.Clip 8 is fixed by bolts on the handle riser 2, its upper surface has one to be slightly larger than 90 ° arc groove, outer tube 7 upper ends by joint 3 with transverse tube 1 is linked into an integrated entity, there is the block 13 of a projection lower end, block 13 places arc groove 12 interior (as shown in Figure 4).A handlebar lock 9 is arranged on the outer tube 7, and handlebar lock inside has (as shown in Figure 2) such as locking plug 10 and pressure springs 11, and locking plug 10 is the awl cylinder.When preparing to deposit bicycle, wheel radial is 90 ° of directions before handlebar and the car, at this moment will lock unlatching, locking plug 10 returns in the lock housing from lockhole 14, outer tube 7 is a running-fit with handle riser 2, under external force transverse tube 1 being driven outer tube 7 horizontally rotates, after outer tube turns over 90 °, the block 13 of outer tube 7 is just in time blocked by the sidewall of the arc groove 12 of clip 8 upper surfaces, at this moment locking plug 10 is just in time aimed at another lockhole 15 of handle riser 2, lock handlebar lock 9 again, locking plug 10 locks with lockhole 15 under the effect of pressure spring 11, outer tube 7 and handle riser 2 are become one, so just handlebar rotate to car before wheel radial be on the parallel direction, car can't be ridden at this moment.

Adopt same step, handlebar can be rotated back to car front-wheel radial shelf and be 90 ° direction, bicycle can have been ridden again.

The utility model can be used for cantilever brake and rim brake bicycle, is that reequip a little on the basis with existing bicycle, applicable to 20 ", 24 ", 26 ", 28 " each model men and women bicycle.

The utility model is practical, and cost is low, and technology is simple, raw MAT'L is easily purchased, and market outlook are wide, remarkable in economical benefits.
