Abstract

The utility model provides a bicycle front fork structure and is characterized in that a front fork frame made of iron materials is combined with a surface layer which is made of plastic materials and covers an outer surface of the front fork by an injection molding mode as a whole, the plastic surface layer can completely cover the surface of the iron fame and be provided with prearranged colors and shapes, thereby the bicycle front fork has the advantages of beautiful appearance, reliability and easy shaping at the expense of relatively low manufacturing cost.

Description

The bicycle front fork structure

The utility model is an a kind of bicycle front fork structure, more detailed it, be meant more easy in a kind of manufacturings, can effectively reduce the course of processing and reduce production costs and the bicycle front fork that is full of variety aesthetic in appearance is constructed.Belong to bicycle assembly parts.

Front fork in the market all is the metal material moulding, wherein again based on iron and aluminum alloy, when utilizing the moulding of iron material matter, system is with pipe fitting made of iron, sheet material is through punching press, forge and procedure of processing such as welding and finish a front fork skeleton, because iron material matter has the misgivings of getting rusty, therefore the surface of this front fork skeleton must be earlier through grinding, thin portion such as finishing handles, afterwards, this front fork skeleton is electroplated or the processing of spraying paint, it is also comparatively durable to make it have comparatively bright-coloured outward appearance, yet, iron material matter front fork is because the restriction in structure and the processing, its external form dullness lacks variation, and, the vestige of each part phase weld of this front fork is cooresponding showy, feasible this iron front fork not only moulding is dull and not attractive in appearance, and the sharpened edge of each part severing position also must be ground, polishing, so, make it after the front fork skeleton is finished, need to process through the finishing of a plurality of steps, cooresponding labor intensive, man-hour, this iron front fork is because cost of material cheaply makes on its cost relative more cheap, and aluminum alloy is because have lightweight advantage, therefore, it generally is to utilize the as cast mode to make its front fork skeleton, form through spraying paint or electroplating again, therefore in moulding, more variation can be arranged, the comparatively smooth smooth-going iron front fork weld mark influence puzzlement attractive in appearance that also do not have of external form, yet, though the aluminum alloy front fork is comparatively attractive in appearance, but relatively its manufacturing cost is higher, certainly, the aluminum alloy front fork of higher unit price also has its fixing market space, but in the time of it will being applied to the bicycle market of low to medium price level, consideration on the cost makes this aluminum alloy front fork seem ineffective in market competition, and with the market demand, can with the price of iron front fork go to buy have aluminum alloy front fork texture article are best choice, and be to be difficult to make the best of both worlds in fact with present situation.

A kind of bicycle front fork structure of the utility model, its objective is: a kind of bicycle front fork structure is provided, its can be cheaper manufacturing cost and obtain the bicycle front fork of variable shaping aesthetic in appearance and easy, reduce the procedure of processing of front fork skeleton and the waste in manpower man-hour, to obtain bigger social benefit and economic benefit.

A kind of bicycle front fork structure of the utility model, it consists predominantly of a front fork skeleton and a plastic surface layer, should be coated on the outside face of this front fork skeleton and constitute the utility model with this plastic surface layer by the front fork skeleton system of metallic material manufacturing.

A kind of bicycle front fork of the utility model structure, its advantage is: manufacture easily, saved manpower man-hour, cost is low, and is handsome in appearance, has the wide market outlook and the market competitiveness.

A kind of bicycle front fork structure of the utility model, it has following accompanying drawing:

Fig. 1 is the utility model schematic appearance.

Fig. 2 is the A-A generalized section on the utility model Fig. 1 and Fig. 3 front fork skeleton coating plastic top layer.

Fig. 3 is the exploded perspective scheme drawing of another embodiment front fork skeleton of the utility model.

Number in the figure is as follows:

10 front fork skeletons, 30 shock-proof front-fork assembly skeletons, 31 sleeve pipes

32 connecting panels, 33 loop bars, 34 shoulders

35 axostylus axostyles, 40 plastic surface layers

Now lift preferred embodiment and conjunction with figs. is described as follows:

A kind of bicycle front fork of the utility model structure, it is made of as shown in Figure 1 integral type front fork skeleton 10 and shock-proof front-fork assembly skeleton 30 and plastic cement top layer as shown in Figure 3.

As shown in Figure 2, with the plastic raw materials of predetermined material and color and luster penetrate be coated on this front fork skeleton outside face to form a plastic surface layer 40, this plastic surface layer 40 is is coated on this front fork skeleton 10 integratedly;

The surface of this iron front fork skeleton is directly penetrated and is coated a plastic surface layer, the vestige that this plastic surface layer can weld each part of front fork skeleton mutually and the sharpened edge of each part severing position cover fully, therefore a plurality of procedure of processings such as commonly using the necessary grinding of iron front fork, polishing, finishing can be reduced, manpower man-hour can be effectively saved.And the lustre pattern of this plastic surface layer can change arbitrarily, at different customer demands and fashion trend, can under the structure of same iron front fork skeleton, change different moulding color and lusters by fast speed, perhaps select the plastic material of different elasticity, density for use, can catch up with popular step fast and a cheap for manufacturing cost and aesthetic in appearance and changeful bicycle front fork is provided.

Claims

1. a bicycle front fork structure is characterized in that it consists predominantly of a front fork skeleton and a plastic surface layer, and this plastic surface layer is coated on the outside face of this front fork skeleton.
