Background technology

Bicycle is a kind of people's commonly vehicles, has many advantages, such as simple and efficient, low-carbon environment-friendly.Bicycle depends on people Itself provides power, and pedal is connect with crank, and the rotation of crank handle turns chain drum drives rear axle, rear axle to be connect with wheel by blockchain, So that bicycle is run.Blockchain is the important component of transmission mechanism of bicycle.Blockchain is because under the gravity nature of itself It hangs down, uses for a long time, blockchain is easy to loosen, the sagging exacerbation of blockchain being below, and is easy to fall off from chain drum, easily hooks ground On sundries, influence the normal operation of bicycle.

After testing, Chinese patent grant number CN204279864U discloses a kind of bicycle blockchain guider, including solid The fixing piece that is scheduled on Chain stay, the guide part being fixedly connected with fixing piece, fixing bolt and it is connect bolt, fixing bolt will be consolidated Determine after part is fixed in lower fork, connection bolt is fixedly connected with fixing piece and guide part, and the guide part is equipped with opening upwards Receiving blockchain holding tank, be equipped in the holding tank and the matched directive wheel of blockchain.

Disadvantage of the existing technology：Bicycle blockchain guider is that bicycle blockchain is led by using the rotation of gear To, but the friction that bicycle blockchain is increased when gear rotation, which makes cycling staff expend more muscle power, rides, and voluntarily Vehicle blockchain guider is not easy to install, and guide gear can not be transferred up and down can only rely on shell progress transfer up and down.

Utility model content

The purpose of this utility model is to provide a kind of bicycle blockchain guiders, have saving and ride physical and be oriented to Height-adjustable advantage is taken turns, solves the problems, such as that muscle power expends greatly and guider can not up and down adjustment.

According to a kind of bicycle blockchain guider of the utility model embodiment, include the anchor ear of two semicirculars, two A anchor ear both sides are equipped with fixing threaded hole, and the lower end of two anchor ears is connected by hinge with U-typed shell, described It is equipped with regulating tank on the two side of U-typed shell, No.1 directive wheel and No. two directive wheels are respectively equipped with inside the regulating tank, The No.1 directive wheel is located above No. two directive wheels, and the No.1 directive wheel and No. two directive wheel sides are equipped with wheel bore, institute State and be equipped with rolling bearing in wheel bore, be nested with rotation axis on the rolling bearing, the both ends of the rotation axis through regulating tank and End point is equipped with matched adjusting nut.

Further, two anchor ear madial walls are coated with nonskid coating.

Further, the hinge is welding with the connection type of anchor ear lower end, U-typed shell respectively.

Further, be all provided on the lateral wall of the No.1 directive wheel and No. two directive wheels it is fluted, the two of the groove Side is equipped with stops.

Further, the lateral wall of the wheel bore and rolling bearing is interference fitted.

Further, screw hole is equipped in the adjusting nut, the screw hole madial wall is equipped with internal thread, the rotation axis It is equipped on the end side wall at both ends and the matched external screw thread of internal thread.

The utility model has an advantageous effect in that compared with prior art：

1, by being oriented to bicycle chain with reeded directive wheel using two so that bicycle chain operates When can along scheduled orbit rotation, without there is a phenomenon where jump chain either float up and down it is violent, by application-oriented Wheel rather than use gear, can friction of the relative reduction to bicycle chain when being oriented to so that when bicycle operates The power smaller needed, saves the muscle power of bicyclist；

2, the upper and lower position of No.1 directive wheel and No. two directive wheels is adjusted by application regulating tank so that guide frame Position can adjust guide frame position at any time with up and down adjustment when it being allow to be mounted on different bicycles, reply is different Chain so that this bicycle blockchain guider universality higher increases practicability.
