Utility model content
Technical purpose of the present utility model be in order to provide a kind of the chain of bicycle can be hidden more attractive in appearance succinct and be convenient to the chain Chain stay internal hidden type structure of enhancing productivity.
In order to realize above-mentioned object, cycle chain Chain stay internal hidden type structure of the present utility model, mainly comprise the vehicle frame with back vent, vehicle seat, the front fork be connected with handlebar, be provided with the front axle of front-wheel, be provided with trailing wheel and the rear axle from sprocket wheel, be provided with the pedal spindle of head sprocket and pedal assembly, be in transmission connection head sprocket and the chain from sprocket wheel, back vent at least includes the Chain stay that two ends place is fixedly connected with rear axle with the pedal tube arranging pedal spindle respectively, described Chain stay be inner hollow and top higher than the elongated rod shape structure of described head sprocket and the outside common tangent from sprocket wheel, the rear portion of the Chain stay of this elongated rod shape hollow structure is the line part with certain length, front end is connected slightly aduncate part with pedal tube be transition curve, the rear end of described hollow Chain stay line part is provided with Chain stay opening, the center of this Chain stay opening with from the sprocket wheel top gear teeth and chain to engage line of centers corresponding, on the outside Chain stay wall that this Chain stay front curvature portion is corresponding with head sprocket, be provided with the Chain stay open front for accommodating described chain, this Chain stay open front runs through the chain cylindrical void having dress chain upward, described chain is passed by chain cylindrical void and is connected with head sprocket with from sprocket engagement, and on chain line of centers and Chain stay open centre place close to each other, or overlap completely.
In cycle chain Chain stay internal hidden type structure of the present utility model, the hollow structure of described Chain stay to be cross section the be figure of eight, described chain cylindrical void and Chain stay opening are all located in the hollow hole passage on the top of this figure of eight cross section structure.
In cycle chain Chain stay internal hidden type structure of the present utility model, on the described Chain stay being provided with the hollow of chain cylindrical void and Chain stay opening, be hollow out state at the side plate of the Chain stay mutually identical with chain height near the side of bicycle quick.Namely the described position being provided with chain channel opening, near the scope that the side of bicycle quick is corresponding with chain height on Chain stay, corresponding medial surface carries out the process of side plate hollow out.
Beneficial effect: cycle chain Chain stay internal hidden type structure of the present utility model, owing to have employed above-mentioned technical scheme, therefore the chain of bicycle can be placed in the Chain stay inside of hollow completely, not only be more convenient for assembling and manufacturing in the process of producing, effectively can reduce production cost, and the outward appearance of product is more succinctly attractive in appearance, is convenient to safeguard and clean, also can avoids the damage in use easily causing chain wheel cover as standard bicycle.
For ease of the detailed content relevant with the utility model and technology are described, accompanying drawing is hereby just coordinated to be described below.
