Abstract

The utility model relates to an accelerator for a movable handlebar of a bicycle, which comprises a flywheel arranged on a front wheel shaft of a bicycle, a chain movably connected with the flywheel, a bracket arranged on a front fork, an outer disc fixedly connected to a bicycle frame, a shaft ring connected with a shaft of the outer disc, a draw rod connected with the shaft ring, and a movable handle which is connected with the upper end of the draw rod and is fixedly installed on a bicycle handlebar, wherein, the chain is connected with the flywheel and the outer disc in a winding way. When a bicycle is ridden, the movable handlebar is drawn up and down, namely the running speed of the bicycle can be accelerated so that people ride the bicycle through labor saving, and the utility model also enables double hands to move, and can be used for cold prevention and heat insulation when people ride the bicycle in winter.

Description

Movable bike handlebar accelerator

The utility model relates to derailleur, particularly a kind of movable bike handlebar accelerator.

Existing derailleur is installed on the bicycle rear shaft mostly, adopts flywheel and chain drive, and the conversion flywheel is to realize speed change under steam.Because these transmission system structures are complicated, productive costs is higher, causes bicycle car load price also than higher.

The purpose of this utility model provides a kind of movable bike handlebar accelerator, affects the moveable cart handle in the time of by bike up and down, can accelerate bicycle running speed, and it is laborsaving to ride.

A kind of movable bike handlebar accelerator described in the utility model comprises that one is loaded on the flywheel on the axletree, one chain that flexibly connects with flywheel, it comprises that also one is loaded on the support on the front fork, one is fixedly connected on the outer dish on the support, one with an outer dish axle bonded assembly axle collar, one with axle collar bonded assembly pull bar, and with pull bar upper end bonded assembly and be fixedly mounted on flexible handle in the bicycle handle bar; Described flywheel is installed on the bicycle front wheel spindle, and described chain connects with flywheel and outer coiling.

In the time of by bike, the cyclist constantly affects the moveable cart handle up and down in bicycle running, can accelerate bicycle running speed, and it is laborsaving to ride, and also can make both hands obtain activity, can keep out the cold warming by bike in winter.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a kind of movable bike handlebar accelerator structure scheme drawing that is installed on the bicycle front-wheel.

Fig. 2 is the collar structure scheme drawing in the above-mentioned accelerator.

Referring to Fig. 1, a kind of movable bike handlebar accelerator comprises that one is loaded on the chain 2 that flywheel 1, one and flywheel 1 on the axletree flexibly connect.It comprises that also one is loaded on the triangular supports 4 on the front fork 10, one is fixedly connected on the outer dish 3 on the support 4, one with an outer dish axle bonded assembly axle collar 5, one and the axle collar 5 bonded assembly pull bars 6, and with pull bar 6 upper end bonded assemblys and be fixedly mounted on flexible handle 7 in the bicycle handle bar.

Flywheel 1 is installed on the bicycle front wheel spindle, coils 3 outward and is installed on the triangular supports 4, and chain 2 is with flywheel 1 and 3 solderless wrapped connections of outer dish.

See Fig. 2 again, dish axle is gone up an axle collar 5 is installed outside, and the axle collar 5 shape that takes the shape of the letter U is equipped with and pull bar 6 lower end bonded assembly bearings 9 at the middle girdle ring place of the axle collar 5.Two support ends on the axle collar 5 tops respectively are equipped with 8, two bearings of a bearing 8 and respectively are connected with support 4.

Pull bar 6 is connected 7 with moveable cart, affects moveable cart 7 with regard to the stretchy axle collar 5 up and down, and drives outer dish 3 and flywheel 1, and then quicken front-wheel and rotate.
