Abstract

The utility model discloses a locating seven-fly shell for a bicycle. The locating seven-fly shell comprises a shell body, wherein the shell body is internally provided with one gear slice, the shell body comprises an inner layer and an outer layer, the outer surface of the inner layer and the outer surface of the outer layer are respectively provided with gear slices, the outer layer is provided with a check ring, and the inner layer, the outer layer and the check ring are an integrated whole. The utility model has the beneficial effects that the locating seven-fly shell is practical, the production cost is low, the intensity of a product is increased, stronger external force can be borne, and the service life of the product is prolonged.

Description

Bicycle use location seven flies shell

Technical field

The utility model relates to a kind of Component of bicycle use, and particularly a kind of bicycle use location seven flies shell.

Background technique

When seven plate gears being installed on bicycle flying, all can use location seven and fly shell, existing location seven fly shell all be divided into interior, in, outer three layers; Because layering is too much, the very thin thickness of internal layer makes in the using process of reality; A little less than the external force resistance ability of shell; Damage easily, in the working life of having reduced product, improved bicycle user of service's user cost.

The model utility content

The utility model technical problem to be solved is the deficiency to existing technology, provides a kind of novel bicycle use location seven to fly shell.

To achieve these goals, the measure taked of the utility model:

Bicycle use location seven flies shell, comprises outer cover body, is provided with gear piece in the outer cover body, and described outer cover body is divided into internal layer and skin, and internal layer and outer field outer surface are provided with gear piece, and skin is provided with back-up ring;

Described internal layer, skin and back-up ring are an integrated integral body.

The beneficial effect of the utility model: practicality, cost of production is low, has improved the intensity of product, can bear stronger external force, has prolonged the working life of product.

Embodiment

Bicycle use location seven flies shell, comprises outer cover body 1, is provided with gear piece 4 in the outer cover body 1, and described outer cover body 1 is divided into internal layer 2 and skin 3, and internal layer 2 is provided with gear piece 4 with the outer surface of skin 3, and outer 3 are provided with back-up ring 5; Described internal layer 2, outer 3 and back-up ring 5 are an integrated integral body.

When using the utility model, the utility model is installed on the bicycle, because the utility model only is divided into internal layer 2 and outer 3; Make the thickness thicker of internal layer 2; The external force resistance ability is stronger, has prolonged the working life of product, has practiced thrift Consumer's user cost; Internal layer 2, skin 3 and back-up ring 5 are an integrated integral body, are convenient to produce, and are formed in one between the parts, have further improved the ability of external force resistance, thereby realize the purpose of the utility model.

Those skilled in the art's simple change and replacement in related domain all are within the protection domain of the utility model.
