Abstract

The bicycle handle rotary brake device solves the problems of modeling and use, and because of general grip braking, fingers are short and the juveniles are inconvenient to use, so the novel handlebar and the brake handle are combined into a whole, one end of the handle is provided with a conical body around the handlebar, the rotary handle rotates from small to large, a thread fixing block is extruded, a thread is pulled to brake, and the purpose of braking is achieved. The brake handle is held in the rider's hand at any time, so that the bicycle brake is convenient for handling emergency and provides safety guarantee for the rider. The brake is suitable for any vehicle type, and the brake handle is removed, so that the brake is simple to manufacture, and the appearance is more concise and attractive.

Description

The bicycle handle spin brake

The utility model relates to bicycle brake device, mainly is meant a kind of handle spin brake device.

Existing bicycle, though kind is a lot, its brake part all is the grip formula that adopts, this brake has several shortcomings in use at least, and the one, it is old that style becomes, and bicycle brake all has only this difference in decades, can not satisfy user's needs; The 2nd, this brake is very inconvenient when handling emergency case, because brake lever is far away from handlebar, if do not having that urgent thing takes place under the situation of psychological preparation, need emergency brake, because it is alarmed at heart, tend to occur grabbing incessantly brake lever, the particularly short people of finger, so just be easy to have an accident; The 3rd, the people that minor and hand are little uses more inconvenient, and promptly handlebar is just grabbed incessantly brake lever often, or grabs less than brake lever at all, so just easier generation safety misadventure; The 4th, because handle brake limitation of design, intermediate support is far away, thus the brake lever pinching very big distance, and the brake point has really only moved seldom, is inconvenient to so again brake a little and the position adjustments of brake lever.

The purpose of this utility model is the above-mentioned shortcoming that has bicycle brake device now to overcome, thereby provides a kind of easy to use, and the bicycle brake device of good looking appearance.

The utility model is to realize like this, the handle spin brake, mainly be that brake gear and handle are linked together, and with the controlling point of handle as brake, because one of handle has around the handle bullet, rotating handles, bullet rotates from small to large, thereby squeezes the solidus piece of the moving line end of stopping, and reach the purpose of brake, owing to be directly to squeeze moving brake cable, squeeze moving distance and be and stop a little equidistantly, can reach quick brake so again, and brake is all being held at any time in rider's hand, no matter finger length need only be rotated handle during brake, all is safe and convenient concerning the rider.

The utility model is described in further detail with embodiment with reference to the accompanying drawings below.

Figure one is the utility model handle spin brake moulding embodiment shape, organigram.

Figure two looks scheme drawing for figure one vertical profile.

Figure three is a double-purpose handle scheme drawing.

1. handle shells among the figure, 2. brake gear shell, 3. bullet, 4. through wires hole, 5. solidus piece, 6. brake cable, 7. tap, 8. fixing tired silk.

As shown in the figure, the utility model handle spin brake is applicable to any type of handle-bar, and handle shell 1 will play dual-use function like this, and it can rotate, so work as tap handle again, rotating handles can brake again.

2 is the brake gear shell.

3 is around handle bullet (convex), it and handle shell are an integral body, one through wires hole 4 is arranged in the middle of the bullet, brake cable 6 is fixed on the 5 solidus pieces by through wires hole 4 and with tired silk, swing handle 1, bullet 3 are also along with rotating from small to large like this, and squeeze the solidus piece 5 that moves the brake cable end, and move backward thereby drive brake cable 6, reach the brake purpose with this.

7 is handle-bar.

8 are the fixing tired silk of brake gear.

The utility model mainly is to have solved moulding and functions of use, brake lever all is held in rider's hand at any time, and is all very convenient no matter finger length is used, and occurs grabbing when urgent phenomenon less than brake lever never again, and owing to reduced former brake handle, the bicycle profile is just succinct attractive in appearance more.

Claims

The bicycle handle spin brake, it comprises rotating handles and the brake gear that is connected with brake cable, it is characterized in that: the rotating handles that leading handle of this handle and brake crank unite two into one, handle one end have one protrude around handle bullet 3, and have can be by brake cable through wires hole 4, the brake cable end has solidus piece 5, and solidus piece and bullet are close to, and bullet rotates with regard to squeezing moving solidus piece and strains brake cable.
2, device according to claim 1 is characterized in that: rotating handles one end has one around the handle bullet, and is provided with through wires hole thereon.
3, device according to claim 1, true feature is: the solidus piece that a may command brake cable is arranged at the brake cable end.
