Description
Technical field
The utility model belongs to bicycle spare parts and accessories field, particularly relates to the double-colored plastic crank of a kind of novel aluminum alloy.
Background technology
Current crank has 3 large classifications, is Al alloy crank respectively, iron crank, plastic crank.Wherein maximum with the use consumption of plastic crank.His advantage is:
1: low price.
2: also can not get rusty because surface has plastic cement to wrap up long-time use.
But plastic crank is in the market all use traditional handicraft to produce (iron core being put in mould, injection plastic rubber shaping).It is single that restriction due to technique result in plastic product color, cannot coordinate with car load collocation of colour.Design and the colour match of whole bicycle are had a strong impact on.Also be difficult to meet the demand of customer to product simultaneously.Therefore plastic crank has just been stamped the label of low side accessory all the time, has no idea to enter mid-to high-end product sequence.
Because still the plastic crank of existing bicycle also exists function singleness, easy fracture, aesthetic is poor, the problem that maintenance cost is high and service life is short.
Therefore, invent the double-colored plastic crank of a kind of novel aluminum alloy and seem very necessary.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of novel aluminum alloy double-colored plastic crank, and there is function singleness, easy fracture to solve the plastic crank of existing bicycle, aesthetic is poor, the problem that maintenance cost is high and service life is short.The double-colored plastic crank of a kind of novel aluminum alloy, comprises aluminium alloy decorative sheet, plastic portions, iron core, crank body, crank fluted disc end and the foot-operated end of crank, and described plastic portions is arranged on the bottom of aluminium alloy decorative sheet; Described crank body is arranged on the midway location that crank fluted disc end and crank ride end; Described crank fluted disc end is arranged on the low order end of crank body; Described crank rides the high order end that end is arranged on crank body.
Described aluminium alloy decorative sheet integrated injection moulding attachment arranges the surface of plastic portions, be conducive to carrying out surface treatment to aluminium alloy decorative sheet, improve surface effect, energy and vehicle frame or other accessory is made to reach collaborative effect, be well positioned to meet the aesthetic needs of designing requirement and customer, reduce maintenance cost, increase the service life.
Described iron core is arranged on the inside of plastic portions, and intensity ratio reflectal crank will be got well, and is conducive to improving intensity, not easy fracture, reduces maintenance cost further, increases the service life.
Described plastic portions specifically adopts PP plastic material to make, the plastic portions that PP plastic material is made have by humidity and illumination effect little, the feature of good stability, is conducive to further reducing maintenance cost, strengthens aesthetic, and then to increase the service life.
The beneficial effects of the utility model are: the utility model is by the setting of aluminium alloy decorative sheet, iron core and plastic portions, improve surface effect, energy and vehicle frame or other accessory is made to reach collaborative effect, be well positioned to meet the aesthetic needs of designing requirement and customer, intensity is high simultaneously, and not easy fracture, is conducive to forever using, further reduction maintenance cost, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
In figure:
1-aluminium alloy decorative sheet, 2-plastic portions, 3-iron core, 4-crank body, 5-crank fluted disc end, the foot-operated end of 6-crank.
Embodiment:
As shown in Figures 1 and 2
The utility model provides a kind of novel aluminum alloy double-colored plastic crank, and comprise aluminium alloy decorative sheet 1, plastic portions 2, iron core 3, crank body 4, crank fluted disc end 5 and crank ride end 6, and described plastic portions 2 is arranged on the bottom of aluminium alloy decorative sheet 1; Described crank body 4 is arranged on the midway location that crank fluted disc end 5 and crank ride end 6; Described crank fluted disc end 5 is arranged on the low order end of crank body 4; Described crank rides the high order end that end 6 is arranged on crank body 4.
Described aluminium alloy decorative sheet 1 integrated injection moulding attachment arranges the surface of plastic portions 2, be conducive to carrying out surface treatment to aluminium alloy decorative sheet 1, improve surface effect, energy and vehicle frame or other accessory is made to reach collaborative effect, be well positioned to meet the aesthetic needs of designing requirement and customer, reduce maintenance cost, increase the service life.
Described iron core 3 is arranged on the inside of plastic portions 2, and intensity ratio reflectal crank will be got well, and is conducive to improving intensity, not easy fracture, reduces maintenance cost further, increases the service life.
Described plastic portions 2 specifically adopts PP plastic material to make, the plastic portions 2 that PP plastic material is made have by humidity and illumination effect little, the feature of good stability, is conducive to further reducing maintenance cost, strengthens aesthetic, and then increase the service life.
The beneficial effects of the utility model are: the utility model is by the setting of aluminium alloy decorative sheet, iron core and plastic portions, improve surface effect, energy and vehicle frame or other accessory is made to reach collaborative effect, be well positioned to meet the aesthetic needs of designing requirement and customer, intensity is high simultaneously, and not easy fracture, is conducive to forever using, further reduction maintenance cost, increases the service life.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
