Description
Technical field
The utility model belongs to the bicycle accessories field, particularly a kind of variable speed bicycle folding crank band chain wheel carrier short handle body.
Background technology
Bicycle is that people like, use the particularly a lot of people of the most general walking-replacing tool, particularly variable speed bicycle to like most; Moreover, along with constantly improving of people's living standard, inhabitation building crowd rolls up, out on tours the crowd roll up, and these crowds wish that urgently bicycle can fold, can take less space so that carry, be convenient to deposit, therefore, folding variable speed bicycle is given birth at once.Crank is to comprise a vitals that must have on all bicycles of collapsible variable speed bicycle, and its effect is that pedal is installed, and cooperates the driving bicycle to advance with sprocket wheel.But the crank on the speed-changeable folding bicycle sprocket wheel was generally split type with the chain wheel support in the past, this split-type structural, and easily loosening and damage, assembling bothers, and is not easy to the installation of other accessories.Transform the folding while as at the crank with speed-changeable folding bicycle, my company also is made as one with sprocket holder and folding crank, the bicycle volume after folding is less making, it is less to take up room, carry, deposit simultaneously more easily, also make bicycle crank more durable in use, it is more time saving and energy saving to assemble, the installation of more convenient other accessories.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of durable in use, not fragile, assembling is time saving and energy saving, make things convenient for variable speed bicycle folding crank that other accessories install with band chain wheel carrier short handle body.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of variable speed bicycle folding crank band chain wheel carrier short handle body, it is characterized in that: formed by short handle body, chain wheel support, the chain wheel support is installed on the short handle body and is made as one, described short handle body is comprised of cylinder, hinge dress connecting portion, locking connecting portion, and hinge dress connecting portion, locking connecting portion are installed in respectively the cylinder upper and lower and are made as one.
And described chain wheel support is shaped with the sprocket wheel mounting jaw on it.
And described sprocket wheel mounting jaw is four to six.
And a described cylindrical end center is shaped with the axis mounting hole, and cylindrical other end center is shaped with axis locknut mounting hole.
And the center of described locking connecting portion is shaped with the pin jack.
Advantage of the present utility model and good effect are:
1. this variable speed bicycle folding crank is with band chain wheel carrier short handle body, and chain wheel support and short handle system are integrated, and assemble more convenient.
2. this variable speed bicycle folding crank is with band chain wheel carrier short handle body, and chain wheel support and short handle system are integrated, and are difficult for becoming flexible not fragile, more durable in use in riding.
3. this variable speed bicycle folding crank is with band chain wheel carrier short handle body, and chain wheel support and short handle system are integrated, and are convenient to the sprocket wheel installation.
4. this variable speed bicycle folding crank is with band chain wheel carrier short handle body, scientific structure design is reasonable, have easy to assembly, durable in use, be convenient to the advantage such as other accessory installations, be a kind of variable speed bicycle folding crank with higher innovation with band chain wheel carrier short handle body.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assembly drowing (folded state) after the utility model and the assembling of long handle body.
Description of reference numerals:
1-chain wheel support, 2-pin jack, 3-axis mounting hole, 4-locking connecting portion, 5-axis locknut mounting hole, 6-cylinder, 7-hinge dress connecting portion, 8-sprocket wheel mounting jaw, 9-short handle embedding slot, 10-button pin, 11-long handle body.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of variable speed bicycle folding crank band chain wheel carrier short handle body, be comprised of short handle body, chain wheel support 1, the chain wheel support is installed in one heart on the short handle body and is made as one, is shaped with sprocket wheel mounting jaw 8 on the chain wheel support, the sprocket wheel mounting jaw is four to six, and present embodiment is four.Described short handle body is comprised of cylinder 6, hinge dress connecting portion 7, locking connecting portion 4, and hinge dress connecting portion, locking connecting portion are installed in respectively the cylinder upper and lower and are made as one.
Cylinder, one end center is shaped with axis mounting hole 3, and its other end center is shaped with axis locknut mounting hole 5.
The locking connecting portion, its center is shaped with pin jack 2.
This principle of work is:
Assembling: with the utility model variable speed bicycle folding crank band chain wheel carrier short handle body, be loaded on long handle body 11 hinges by hinge dress connecting portion, and by the axis mounting hole the utility model is installed on the axis, with the axis locknut axis and the utility model are locked; By the sprocket wheel mounting jaw on the chain wheel support sprocket wheel is installed on the chain wheel support.When riding, short handle body embedding slot 9 on the long handle body is inlaid in the short handle body, and with the button pin 10 that is installed on the long handle body long handle body and short handle body is fixed, like this, under the cooperation of the accessories such as pedal, long handle body, short handle body, chain, can drive bicycle advances; When folding, downward button push pin makes in the pin jack of button pin from the short handle body locking connecting portion and withdraws from, and upwards pulls the long handle body, can with the long handle folded body to vehicle frame, dwindle taking up room and volume of bicycle.Because chain wheel support and short handle system are integrated, so easy to assembly simple; Because chain wheel support and short handle system are integrated, when riding, chain wheel support and short handle body support frame are difficult for loosening, and be not fragile, durable in use; Since the chain wheel support with the short handle system is integrated and the chain wheel support on be shaped with the sprocket wheel mounting jaw, sprocket wheel installation is time saving and energy saving.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
