Abstract
The utility model discloses a core shaft of a bicycle rapidly-detached device, which comprises a core shaft, wherein the core shaft is about in a long-rod shape; a location block is screwed at one end of the core shaft; the core shaft is provided with a plurality of grooves; a forcing block is arranged on the other end of the core shaft; and the forcing block can selectively extruded to the location block. By the core shaft of a bicycle rapidly-detached device, the total weight of a bicycle can be reduced, the cost can be effectively controlled, and electric wires are convenient to penetrate at both sides of bicycle wheels.
Description
Technical field
The utility model refers to a kind of axle of bicycle quick-detaching device especially about a kind of wheel axle.
Background technology
Recently, the use of bicycle changes the outdoor activity instrument into from the vehicle gradually, and whether for convenience detach bicycle and the industry that merrily and lightheartedly is easy to carry about with one become the important indicator that the customer chooses bicycle.
Fast removable mandrel structural improvement referring to TaiWan, China TWM285522 patent, the axle of this utility model is to provide a through hole in the axle central interior, alleviate the weight of this axle by this, and can in through hole, wear electric wire, but this axle is elongated straight-bar, it is higher to provide the through hole difficulty, and cost of manufacture is risen.
The bar reinforcing structure that is spirally connected referring to TaiWan, China TWM325968 patent, the axle of this utility model is to coat with two kinds of materials to form, alleviate the weight of this axle by this, but this axle not only needs to provide through hole in central interior, more need sheathed another thin bar in through hole, cost of manufacture is further improved.
In addition, the partially self car is mounted with electric installations such as electric light, and the connection of wheel both sides electric wire need be walked around lateral wheel and carries out, and wiredrawn electric wire not only increases bicycle weight, also increases to collude mutually and pulls the risk that meets accident.
The utility model content
Main purpose of the present utility model is to provide a kind of axle of bicycle quick-detaching device, makes bicycle weight slim and graceful, and effectively controls manufacturing cost.
Secondary objective of the present utility model is to provide a kind of axle of device for quickly disassembling of bicycle, makes the electric wire of the required use of bicycle can be arranged in the wheel axle, the unlikely in disorder wheel periphery that exposes to.
For achieving the above object, the utility model is by the following technical solutions:
A kind of axle of bicycle quick-detaching device, this axle generally is an elongated rod shape, and this axle one end spiral shell is established a positioning block, and this axle is provided with long recess.
Described groove is generally to be the cambered surface indent.
Described groove extends to this axle two ends.
Described groove bearing of trend generally is parallel with this axle length bearing of trend.
Described groove is several.
Described two relative grooves can be the connection penetration state.
The axle of described bicycle quick-detaching device, it also comprises:
A positioning block, this locating piece spiral shell are located at this axle one end;
One urgent, this urgent other end that is fixed in this axle.
Described urgent comprises a cam and leader, and this handle is fixed in this cam, and this handle and this cam are with respect to this axle pivot pendulum.
The axle of described bicycle quick-detaching device, it also comprises two elastic components, and two these elastic components are located at this axle, and two these elastic components are between between this locating piece and this urgent.
Advantage of the present utility model: the axle of the device for quickly disassembling of the resulting bicycle of the utility model, on this axle, be provided with several long recess, reduce the bicycle overall weight after the installing, those grooves provide axis wheel to place the required space of electric wire, this axle profile is processed easily, has effectively controlled tooling cost.
