Abstract

The utility model relates to a foldable bicycle handlebar which comprises a middle seat, two handlebars, a bolt and a fastener, wherein, two sides of the middle seat are connected with one handlebar through a pin shaft. In the riding process, the handlebars are locked by the fastener through the pressure of the bolt to be fixed; when the bolt is loosen, the locking force on the head end, of the fastener is eliminated; and the handlebars can rotate around the pin shaft and are combined together to achieving the goal of reducing the width of bicycles.

Description

A kind of Folding Bicycle handgrip

Technical field

The utility model relates to the handgrip of a kind of bicycle or battery-driven car, three-wheel vehicle.

Background technology

Folding bicycle is easy to carry with it and saves the characteristics of parking space and be subjected to extensively liking of people.

Common folding bicycle is a folder to be installed the car beam is divided into two sections of front and back on the car beam, to reduce the length of bicycle; And a folder is installed on handle riser to reduce the height of bicycle.The folding of these two kinds of positions used commonplacely, also comparative maturity.

But at some in particular cases, handlebar need be folded up, to reduce the width of bicycle; Still do not have ripe in the folding present industry to handlebar and desirable mode, common method such as Fig. 1 that adopts, there is a sleeve pipe 02 centre, and the driver inserts 01 and 04 from the two ends of sleeve pipe 02 respectively.Respectively establish a bullet pin 03 on handgrip, when

handgrip

01 and 04 was inserted into its fixed position, the bullet pin was in the knock hole of setting on the sleeve pipe, and handgrip comes off in the time of can preventing to ride.Must earlier bullet pin 03 be depressed when folding, then driver's handle be extracted out from sleeve pipe, as Fig. 2 (a); Between two

handgrips

01 and 02, link as the consequently folding defensive position of Fig. 2 (b) not coming off voluntarily with a tightrope 05.

This mode is simple in structure, but the action trouble is easily loosening.Use generally on Kickboard Scooter, some bicycles also have employing, but bicycle is to reduce to rock and at the two ends of sleeve pipe fluting and respectively add one group of fast disassembly type tube bank when adopting.Though reduced like this to rock, when folding action loaded down with trivial details, the aesthetic feeling of outward appearance is relatively poor, is difficult to promote.

Summary of the invention

In order to address the above problem, it is a kind of easy to operate that the utility model provides, and coupling mechanism force is big, and safe and reliable handgrip foldable structure.Its good rigidly, folding convenient is made simple, elegant in appearance.

The both sides of seat 09 during structure of the present utility model such as Fig. 3,

handgrip

06 and 10 are connected in bearing pin 12 respectively, and can rotate around bearing pin 12.There is a pin 11 at the middle part of middle seat, and this pin and bolt 08 link.Be with a spring 13 and a fastener 07 on the bolt 08, the concaveconvex shape on both sides, fastener 07 below is corresponding with the nose shape of handgrip 06 and handgrip 10.When being rotated in the forward bolt 08, it compresses fastener 07 downwards, and concavo-convex the cooperatively interacting of the concaveconvex shape on both sides, fastener 07 below and handgrip 06 and handgrip 10 heads is locked handgrip; Be riding condition.

If in the time of must folding, only need the handle contrarotation of bolt 08, fastener 07 moves up under the effect of spring 13, leaves the head of handgrip, just handgrip can rotate (as Fig. 4), folding is got up.

If bolt 08 uses handle type quick detach bolt instead,, move handle 14 and fastener 07 is pressed down or loosen then as Fig. 5 (a); Also can add a hand rotary nut 15 with screw rod, as Fig. 5 (b), swivel nut 15 can press down fastener 07.

Description of drawings

Fig. 1 is the structural representation of existing folding handgrip.

Fig. 2 is existing folding handgrip folding process scheme drawing.Wherein Fig. 2 (b) is folding back state.

Fig. 3 is a structural representation of the present utility model.Handgrip is in the position when riding during this state.

Fig. 4 is the scheme drawing of the utility model folding process.Wherein Fig. 4 (b) draws close the position view of state for folding back two handgrips.

Fig. 5 is other two kinds of scheme scheme drawings of bolt.

Fig. 6 is that the utility model connects the scheme scheme drawing with the car standpipe.

The serial number name that indicates among the figure is:

01, handgrip 02, sleeve pipe 03, bullet pin 04, handgrip 05, tightrope 06, handgrip

07, fastener 08, bolt 09, middle seat 10, handgrip 11, pin 12, bearing pin

13, spring 14, quick detach handle 15, hand rotary nut 16, handle riser 17, extension pipe

The specific embodiment

What anticipate shown in Fig. 6 is a kind of connecting mode of folding handgrip of the utility model and cycle arm, and middle seat 09 is linked as Fig. 6 (a) with handle riser 16 by an extension pipe 17; Perhaps directly middle seat is connected on the handle riser 16 as Fig. 6 (b).Connecting mode can weld, and also can be holding tube folder and screw-threaded coupling.

Extension pipe 17 can manufacture siamesed with middle seat and also can weld, then with thread locking or be welded on the handle riser.

Claims
