New type description: [New technology field] This creation department has a variety of bicycle wheel structure, especially a single speed application, and to make the wheel advanceable, and the ship's miscellaneous wheel drive It can improve the transmission efficiency and provide convenient combination and stable combination. [Prior Art] The wheel of a self is mainly located at the center of the wheel, which provides the spokes and the outer lining, so that the axle is inserted therein, and the relative rotation is generated. In the case of other wheels, it is usually A front fork tube is arranged on both sides of the hub, and the fork is connected to both ends of the axle; the rear wheel is provided with a rear fork g on both sides of the hub, and the rear tube and the axle are The two ends are connected; in this case, after each b month j: the wheel is in a fixed state 'the wheel and its outer diameter ring light wheel' and the other end of the spoke bar is rotated. The wheel hub structure of the bicycle rear wheel is provided with a chain plate assembly in addition to the aforementioned rear fork pipe, thereby accepting a crank and a pedal driver of the five-way portion in cooperation with a chain; the chain contact can be further divided into "Single-speed chain" and "multi-player" are the two categories of "single-speed chain", which means that a single chain is placed on the opposite side of the wheel to achieve a single speed sprocket ratio and cannot be shifted; "Flywheel" is also composed of a plurality of chain-shaped sprocket and is arranged on one side of the wheel, that is, a plurality of speed sprocket ratios can be achieved. Since the chain assembly is mostly combined with one side of the hub, so that the wheel can be driven to produce synchronous rotation, the transmission mode can be divided into two types: "direct type" and "ratchet type", among which "direct type" The finger chain assembly and the hub are directly combined to form a direct force material. The aim is to have a transmission effect regardless of the forward or reverse rotation; the "ratchet" is further provided in the miscellaneous and the wheel paste - The ratchet and the group are provided to provide a one-way rotating gear transmission effect, and the reverse rotation is not used for the transmission effect. The direct-type bicycle hub structure of the direct type, such as the "transformable bicycle flower and transmission gear combination structure" disclosed in the new patent No. 095208735, is mainly for the transmission gear of the bicycle rear wheel hub shaft. Therefore, it is possible to limit the number of teeth of the dog's broken transmission gear, and then to give it a turn after the chain is set up, and the axle of Wei by Guicai consists of a flower hub, in which both ends of the shaft tube are separately formed. Roulette, the set of wheels for the wheels is set to be 'with the bearing between the shaft tube and the inner-mounted axle, respectively, which can be used to give the shaft tube to move the wheel _ smooth rotation, while the shaft tube-end is locked It has a separate transmission gear, which can be used to touch the gear and the bicycle ugly pull button, to achieve the pedaling: pedal reading and wheel lie performance; its ship system is: the wheel $ axis s $ lock α transmission gear The system is combined with the inner diameter lock of the shaft tube, and is provided with a (four) pattern at the end of the miscellaneous section, and the base of the _ wheel is provided with an outer r. The hole, according to the = 彳 = 喃 嶋, 嶋 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上The conventional "snap-wheeled" single-speed bicycle should be the new model patent No. 212677. The bicycle hub drive sprocket structure of the tear-off road is made up of a flower hub, a ratchet, a sprocket and a lock. The knot is composed of a knot, wherein the center of the hub has a mandrel for fixing and fixing with the frame, so that the hub can freely rotate on the spindle, and can be combined with the wheel by using the arrangement of the hub A sprocket seat is arranged on the side of the 彳t·hu. The sprocket seat is provided with a plurality of positioning ribs on the side of the sprocket seat, and a stalk is formed on the outer side of the sprocket, and the sprocket is formed on the rim of the sprocket. The teeth are arranged such that the transmission sprocket provided on the pedal lever can be connected by a chain. The locking member has a female threaded hole at the center of the locking member. The characteristic is that the ratcheting towel body has a through hole with a mortise groove. On the outer periphery, there are ratchets on the outer circumference, so that the spurs are placed on the ratchets of the ratchets. The sprocket is unidirectionally driven by the sprocket: the sprocket has a accommodating hole in the center and the outer side has a rim. It is an open opening, and the card/capture card can be used to insert a card into the card to close the opening. [New content] 2 unveiled shots, all of which are "single-speed" wheel hub structure design, the front of the small tooth is the main 揺 观 练 练 练 small small outer diameter and has a r to the other - inserted with its end screw The part recorded within the circle, by the wheel in the Qing = catch than the Lang; the technical characteristics of the request structure of the latter is attached to the spine through the hole, the outer edge of the Qing Weng ratchet, so that the roll hole, the outer side has a retaining edge, the inner 'and The card groove can be used to block the knot, so that the ratchet can be engaged, and the sprocket can be driven early, and the sprocket is formed in the center of the sprocket and is opened. The internal opening is screwed into the sprocket seat to seal the open opening, and the upper threaded portion of the lock is placed. The difference between the above-mentioned shouting and stagnation is that the former is the chain, (ie, the smooth wheel) is directly employed on the hub; the latter is used to locate the female After the ratchet and the sprocket on it are sleeved on the secret hub, the sprocket is forced to _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In other cases, the transmission gear is "spinned directly" on the structure of the flower hub. Because the chain plate rotates synchronously with the rotation of the wheel, the volume f is gradually loosened, and the latter will have to extend the sprocket surface to a considerable extent. The size (4) can be easily set on the ratchet wheel and the sprocket on it, and the threaded section of the front end of the sprocket seat makes the overall flower hub exhibit a relatively long axial dimension 'not lightweight; therefore, the creator of the case Another type of single-speed bicycle hub structure is provided, which is a "direct" hub structure with two-way rotation and transmission effect. (Technical means for solving the problem) In view of the present invention, the volley structure of a single-speed bicycle includes a hub group having a hub shell formed with a convex ring on one side thereof. a plurality of first fitting portions are disposed on a side edge surface of the coupling seat; a single speed chain plate group is connected to the outer edge surface of the coupling seat, and a plurality of fastener elements are arranged around the circumference portion thereof.
