Abstract
The utility model discloses a hub structure used in a fixed gear bicycle. The hub structure comprises a hub shell and a fly wheel, and is characterized in that the hub structure further comprises a hub fixing base arranged at one end of the hub shell, the hub fixing base and the hub shell are coaxially arranged, and first bolt holes evenly distributed are formed in the hub fixing base; second bolt holes corresponding to the first bolt holes in position are formed in the fly wheel, and the hub fixing base is arranged between the hub shell and the fly wheel and fixedly connected with the fly wheel through a screw; the hub fixing base is in a gear shape, and the first bolt holes are formed in fixing base gears; the ratio of the number of first bolt holes to the number of the fixing base gears is 1:1. The hub structure has the advantages that the structural design is reasonable, and the hub structure is easy to produce and machine; the hub fixing base and the fly wheel are tightly locked through the screw, the hub shell and the fly wheel are not prone to damage no matter whether a user pedals the bicycle to move forwards or backwards, the abrasion to the hub structure is reduced, and the service life of the hub structure is prolonged.
Description
Technical field
The utility model relates to a kind of hub structure, is specifically related to a kind of use at the hub structure extremely flying on bicycle, belongs to bicycle accessories field.
Background technology
Extremely fly (Fixedgear) bicycle, Chinese name: field vehicle, single speed car, can be just ride, also can fall and ride, by controlling flywheel, rotate to realize brake.
At present, use on the market is extremely flying hub structure on (Fixedgear) bicycle as shown in Figure 1,, by the coordinating of binding ring 1, flywheel 2 and tooth line 4 above flower-drum housing 3, flywheel is fixed.But there is following shortcoming in existing hub structure:
1, people steps on forward foot-operated time, and flywheel can follow the tooth line cw (seeing from right to left) of flower-drum housing to rotate forward, and can turn tighter and tighter, finally causes the flywheel flower-drum housing of grinding away;
2, people steps on foot-operated time backward, and flywheel rotates counterclockwise in the opposite direction, and binding ring adopts anti-tooth locked, and then locked flywheel, thereby control flower-drum, rotates to brake.Like this, the braking strength that the locking strength out of reach flywheel of binding ring and flower-drum housing tooth line is stepped on backward, easily makes the sliding tooth of flower-drum tooth line, thereby flower-drum is damaged, and shortens its service life.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of durable, nonabradable use at the hub structure extremely flying on bicycle.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of use is at the hub structure extremely flying on bicycle, comprise: flower-drum housing and flywheel, it is characterized in that, also comprise: be arranged on aforementioned flower-drum housing one end and with the flower-drum permanent seat of the coaxial setting of flower-drum housing, on aforementioned flower-drum permanent seat, be formed with well-distributed the first bolt hole; On aforementioned flywheel, be formed with second bolt hole corresponding with the first bolt hole position, flower-drum permanent seat is arranged between flower-drum housing and flywheel and is fixedly connected with by screw with flywheel.
Aforesaid use, at the hub structure extremely flying on bicycle, is characterized in that, aforementioned the second bolt hole with the quantity of the first bolt hole than being 2:1.
Aforesaid use, at the hub structure extremely flying on bicycle, is characterized in that, aforementioned flower-drum housing and flower-drum permanent seat are adopted made of plastic.
Aforesaid use, at the hub structure extremely flying on bicycle, is characterized in that, aforementioned flywheel adopts corrosion-resistant steel to make.
Aforesaid use, at the hub structure extremely flying on bicycle, is characterized in that, aforementioned flower-drum permanent seat is gear-like, and the first bolt hole is formed on the permanent seat gear teeth.
Aforesaid use, at the hub structure extremely flying on bicycle, is characterized in that, aforementioned the first bolt hole with the quantity of the permanent seat gear teeth than being 1:1.
Usefulness of the present utility model is: reasonable in design, easily production and processing; By screw, make flower-drum permanent seat and flywheel firm locking, no matter car is to step on forward or step on backward, and flower-drum housing and flywheel are all not easy to damage, thereby has reduced the wearing and tearing of hub structure, has extended its service life.
Accompanying drawing explanation
Fig. 1 is that existing use is at the structural representation that extremely flies the flower-drum on bicycle;
Fig. 2 is the structural representation of flower-drum of the present utility model.
The implication of Reference numeral in figure: 1-binding ring, 2-flywheel, 3-flower-drum housing, 4-tooth line, 5-flower-drum permanent seat, 6-the first bolt hole, 7-the second bolt hole, 8-screw.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
With reference to Fig. 2, use of the present utility model, at the hub structure extremely flying on bicycle, comprising: flower-drum housing 3, flower-drum permanent seat 5 and flywheel 2.Wherein, be formed with well-distributed the first bolt hole 6 on flower-drum permanent seat 5, flower-drum permanent seat 5 is arranged on one end of flower-drum housing 3, and coaxial with flower-drum housing 3; Accordingly, on flywheel 2, be formed with second bolt hole 7 corresponding with the first bolt hole 6 positions.Flower-drum permanent seat 5 is arranged between flower-drum housing 3 and flywheel 2, and flower-drum permanent seat 5 is fixedly connected with by screw 8 with flywheel 2.
Hub structure of the present utility model, owing to making flower-drum permanent seat 5 and flywheel 2 firm lockings by screw 8, no matter car is to step on forward or step on backward, and flower-drum housing 3 and flywheel 2 are all not easy to damage, thereby reduced the wearing and tearing of hub structure, extended its service life.
As a kind of preferred scheme, the quantity of the second bolt hole 7 and the first bolt hole 6 is than being 2:1.If a certain the second bolt hole 7 damages, rotary flyweights 2 makes its distance that turns over second bolt hole 7, and the second bolt hole 7 that makes to damage is avoided and being connected of screw 8, and without the flywheel 2 more renewing, has saved cost; Meanwhile, increase the weight that the number of openings can suitably alleviate flywheel 2.
More preferably, flower-drum housing 3 and flower-drum permanent seat 5 are adopted made of plastic, can alleviate the weight of flower-drum integral body.
As a kind of preferred scheme, flywheel 2 adopts corrosion-resistant steel to make, and can reduce wear, improve service life.
In the utility model, flower-drum permanent seat 5 is gear-like, and the first bolt hole 6 is formed on the permanent seat gear teeth, and the first bolt hole 6 is preferably 1:1 with the quantity ratio of the permanent seat gear teeth, so, can effectively alleviate the weight of flower-drum permanent seat 5, makes the running of flower-drum more flexible.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
