Description
Technical field
The utility model is related to the technical fields of bicycle, and in particular to a kind of monoblock type bicycle wheel disc.
Background technology
It is a kind of important bicycle accessories from bicycle wheel disc, is used to convert manpower to the rotation of wheel, for certainly
Driving provides power.Bicycle wheel disc in the prior art is varied, most of to be made of metal, simple in structure, cost compared with
It is low.But the shortcomings such as in the actual use process, there is weight greatly, does not have elasticity and easily gets rusty.Therefore, one is researched and developed
Kind is light-weight, intensity is high and has the bicycle wheel disc for placing chain, for the weight of reduction bicycle, improves efficiency of riding,
Have great importance.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of bicycle wheel disc, using modular design,
Improve the clothes that wheel disc during can effectivelying prevent use while repair simplicity is spent makes user dirty.
The utility model is realized by technical solution below：
A kind of monoblock type bicycle wheel disc, the monoblock type bicycle wheel disc uses integral structure, whole by plastics material
Material is made, and the monoblock type bicycle wheel disc includes disk body, gear part and external reinforcing circle；The disk body circle centre position is provided with peace
Fill hole；The gear part is set on the outer wall of disk body, and gear part upper surface is provided with the gear teeth with chain interoperation；The outside
Stiffening ring is two loop configuration, is set on disk body outer wall, and gear part is wrapped among it by two external reinforcing circles, high
Degree has the top of introversion more than the outer diameter and external reinforcing circle of gear part；Buffer layer is provided with outside the disk body, it is described slow
It rushes layer and includes the equally distributed exit orifice of multiple circumferential directions, the exit orifice is arcuate structure, and the arcuate structure is towards outside；Disk body is being pacified
It is arranged alternately radially distributed strip-shaped hole and bar shaped reinforcing rib between dress hole and exit orifice.
Preferably, the wheel disc is made of makrolon material.
Preferably, the wheel disc is provided with ring stiffener around mounting hole.
The bicycle wheel disc provided in the utility model, using plastics integral structure, production cost is low and efficient；It is logical
External reinforcing circle is arranged in third wheel teeth portion both sides, and effectively chain can be fixed in wheel teeth portion, prevent it from moving left and right, improve
Chain fixed stability；By using the inner panel and outside plate of makrolon material, construction weight is reduced, improves and rides
Effect.It reduces weight, while wheel disc being made to have by the design of buffer layer while ensureing wheel disc rigidity and intensity
Preferable elasticity, is not easy to be damaged because of collision；By the alternating radial distribution of strip-shaped hole and bar shaped reinforcing rib, improve
The uniformity of stress dispersion, can effectively improve service life；By the shape for advanced optimizing strip-shaped hole and bar shaped reinforcing rib
Shape can effectively prevent the generation of stress concentration.
Description of the drawings
Fig. 1 is the structure chart of bicycle wheel disc in the utility model；
Fig. 2 is the assembling schematic diagram of bicycle wheel disc in the utility model.
Specific implementation mode
The technical solution of the utility model is described in detail below by specific embodiment, but this practicality is new
The range of type is not restricted by the embodiments.
As shown in Figs. 1-2, a kind of monoblock type bicycle wheel disc is present embodiments provided, the monoblock type bicycle wheel disc is adopted
Whole to be made of plastic material with integral structure, the monoblock type bicycle wheel disc includes that disk body 1, gear part 2 and outside add
Strong circle 3；1 circle centre position of the disk body is provided with mounting hole 11；The gear part 2 is set on the outer wall of disk body 1, in gear part 2
Surface is provided with the gear teeth with chain interoperation；The external reinforcing circle 3 is two loop configuration, is set on 1 outer wall of disk body, two
Gear part 2 is wrapped among it by a external reinforcing circle 3, and height is more than the outer diameter of gear part 2 and external reinforcing circle 3 is with interior
The top inclined；Buffer layer is provided with outside the disk body 1, the buffer layer includes the equally distributed exit orifice 4 of multiple circumferential directions, described outer
Hole 4 is arcuate structure, and the arcuate structure is towards outside；Disk body 1 has been arranged alternately radially between mounting hole 11 and exit orifice
The strip-shaped hole 5 and bar shaped reinforcing rib 6 of distribution；The wheel disc is made of makrolon material.
Above embodiment is only the preferred embodiment of the utility model, it should be pointed out that, for ordinary skill
For people, what is carried out under the premise of not departing from the utility model is partly improved, still in the scope of protection of the utility model it
In.
