Description
Technical field
The utility model is related to technical field of bicycles, specially a kind of carbon fiber bicycle crank.
Background technology
Bicycle can be used for riding instead of walk, go on a journey as the vehicles of environmental protection；Increasing people is using bicycle as strong
Body equipment is gone on a tour for exercise of riding, bicycle；Bicycle is also a sports campaign in itself, have road race,
Mountain bike, Track cycling, stunt bicycle race etc..Highway bicycle refers to for making on smooth highway road surface
Car type, because slippery traffic surface resistance is smaller, the design of road cycling is considered more greatly at a high speed, often using can decelerating wind resistance
Lower curved handle, narrower hyperbar lower resistance cover tire, gear is higher, and the mountain-climbing offroad vehicle of impeller diameter ratio typically is all big, due to
Vehicle frame is not required to need to strengthen as mountain bike with accessory, so often lighter in weight, efficiency is very high when being ridden on highway.By
In vehicle frame without strengthening again often using simple efficient rhombus design, highway car is bicycle the most graceful.Bicycle is
Overcome one of optimal instrument of cardiac function defect.Have in the world people more than half be die from it is cardiopathic.Bike riding is not only
Can by leg motion compresses blood flow, and blood from blood vessel distal drawn back heart, in fact but enhanced simultaneously micro-
Vascular tissue, bicycle is to need the motion of a large amount of oxygen.The different people's leg length of height is also different, and they should not use when cycling
The crank equally grown.Because the equally long circle for being equivalent to allow the leg of different length to draw same radius of crank, if this circle is big
, the little chap of short legs is not suitable for；If this handle is short, tall person does not send out power.Crank be on bicycle one it is important
Structure, many times the quality of crank determine the ability to act of bicycle, many cranks use metal material at present,
It is easily damaged after long-time use, and quality is larger, therefore devise a kind of carbon fiber bicycle crank.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of carbon fiber bicycle crank, including song
Handle main body, the crank body is made of carbon fibre material, and carbon fiber braiding layer is provided with the outside of the crank body, described
Crank body upper end is provided with the first connector, and the crank body lower end is connected with the second connector, first connector
Fluted lines is set with being provided with inside the second connector on metal ring, the metal ring inwall, the crank master
Internal portion is provided with filling block, and the filling block includes being provided with some air-vents on titanium alloy substrate, the titanium alloy substrate.
As a kind of preferred technical scheme of the utility model, the titanium alloy substrate left and right ends are provided with anti-slip veins
Road.
As a kind of preferred technical scheme of the utility model, first connector and the second connector outer application
OSP anti oxidation layers.
As a kind of preferred technical scheme of the utility model, the metal ring is made of 317 type stainless steel materials.
Compared with prior art, the beneficial effects of the utility model are：By the material based on carbon fiber sheet, build
Crank body, in one layer of carbon fiber braiding layer of crank body outer side covers, increase equipment bears dirty performance, protects internal carbon fibers plate
Material, by the use of carbon fibre material, considerably increases the service life of equipment so that crank is more durable, it is not necessary to pass through
Crank is often changed, is worthy to be popularized.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model filling block structural representation.
In figure：1- crank bodies, 2- carbon fiber braiding layers, the connectors of 3- first, the connectors of 4- second, 5- metal rings,
6- groove lines, 7- filling blocks, 8- titanium alloy substrates, 9- air-vents, 10- non-slip textures, 11-OSP anti oxidation layers.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of carbon fiber bicycle crank, including song
Handle main body 1, the crank body 1 is made of carbon fibre material, and the outside of crank body 1 is provided with carbon fiber braiding layer 2,
The upper end of crank body 1 is provided with the first connector 3, and the lower end of crank body 1 is connected with the second connector 4, described
It is provided with inside one connector 3 and the second connector 4 on metal ring 5, the inwall of metal ring 5 and fluted lines is set
6, filling block 7 is installed, the filling block 7 is included on titanium alloy substrate 8, the titanium alloy substrate 8 inside the crank body 1
Some air-vents 9 are provided with, the left and right ends of titanium alloy substrate 8 are provided with non-slip texture 10, first connector 3 and
The outer application OSP anti oxidation layers 11 of two connector 4, the metal ring 5 is made of 317 type stainless steel materials.
The utility model when in use, by the sheet material of carbon fibre, is molded into crank shape, inside edge wherein
