A kind of bicycle wheel disc is the utility model is related to, more particularly to a kind of bicycle D-shaped wheeling disk structure.Its structure includes the wheel disc being fixed on bicycle middle shaft, wheel disc is in anti-D fonts, slided in described wheel disc outer rim and be provided with sliding chain, the tooth coordinated with bicycle chain is provided with described sliding chain, telescopic pedal bar is provided with described axis, axis described in the inner connection of described telescopic pedal bar, the middle part of described telescopic pedal bar pass through connecting rod and connect described sliding chain, the outer end connection pedal of described telescopic pedal bar.A kind of bicycle D-shaped wheeling disk structure of the present utility model, it can increase efficiency when riding firmly, so that ride medium velocity is faster, more save muscle power.
Description
Technical field
A kind of bicycle wheel disc is the utility model is related to, more particularly to a kind of bicycle D-shaped wheeling disk structure.
Background technology
In daily life we have seen that bicycle majority be circular chain wheel structure, such structure rides at us
During have some problems, this problem be we in firmly pushes pedals when pedal is in higher or lower position, I
Firmly car also less accelerate, and trample that firmly torque is maximum, and at this moment firmly effect is just fine when only pedal is in horizontal.
And it is useless that current circular wheel disc, which has led to the acting of riding of a very big part, ridden so as to add
The consumption of person, cycle and be easier fatigue.
Utility model content
In order to solve problem of the prior art, the utility model provides a kind of bicycle D-shaped wheeling disk structure, and it can increase
Add efficiency firmly when riding, so that ride medium velocity is faster, more save muscle power.
Technical scheme is as follows used by the utility model：
A kind of bicycle D-shaped wheeling disk structure, including the wheel disc being fixed on bicycle middle shaft, wheel disc is in anti-D fonts, described
Wheel disc outer rim on slide be provided with sliding chain, be provided with described sliding chain with bicycle chain coordinate tooth, it is described
Telescopic pedal bar, the axis described in the inner connection of described telescopic pedal bar, described telescopic pedal bar are provided with axis
Middle part pass through the described sliding chain of connecting rod connection, the outer end connection pedal of described telescopic pedal bar.
Wheel disc is two, and it is symmetrically set in the both sides of axis.
Wheel disc outer rim is provided with sliding groove, and both sides are provided with bearing in described sliding groove, and described sliding chain is slided and is embedded in
Between two side bearings in described sliding groove.
Telescopic pedal bar includes the interior bar of connection axis, and the outer Slideslip of described interior bar has outer loop bar, and described connecting rod is set
It is placed on outer loop bar.
A kind of bicycle D-shaped wheeling disk structure of the present utility model, due to when firmly trampling, the track of wheel disc be vertically to
Under, thus can when we firmly trample downwards, when can there is very long one section of effect and the circular chain wheel to be in horizontal as.
Efficiency firmly is added, so that ride medium velocity is faster, more saves muscle power.
In order to ensure that the track of two pin in left and right is all anti-D fonts, using the side for all pacifying wheeling disk structure on bicycle both sides
Formula solves.
A kind of bicycle D-shaped wheeling disk structure of the present utility model, wheel disc is made anti-D fonts, transition position makes it at turning
It is round and smooth, in order to it is unlikely to break occur during pedal after a while, why right vertical is circle on the left of downwards,
It is in order to which only pedal rod mutually slides when firmly, when not trampling firmly, connecting rod does not slide mutually, is rubbed so as to reduce
Power acting is wiped, reduces connecting rod heating.A circle sliding chain is twined on wheel disc, wheel disc is groove structure when sliding chain is combined with wheel disc, is prevented
Sliding stop chain releasing.Bearing is set to reduce the friction between sliding chain and wheel disc in the groove that sliding chain is combined with wheel disc
Power.
Connecting rod between pedal and axis makes two-part, and mutually nested structure can be slided mutually, pedal and outside
Outer loop bar is connected, and the side connecting rod being had an effect during traveling is trampled stretches, constant in another side length.Also have on outer loop bar
A piece connecting rod is connected with sliding chain, drives sliding chain to rotate by trampling, so as to drive bicycle chain to travel car.
Connecting rod is made up of a bar with the pipe outside it, between have a bearing, reduce and rubbed when relatively rotating.
The beneficial effect that technical scheme provided by the utility model is brought is：
It can increase efficiency when riding firmly, so that ride medium velocity is faster, more save muscle power.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is a kind of structural representation of bicycle D-shaped wheeling disk structure of the present utility model.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
Embodiment one
As shown in Figure 1, a kind of bicycle D-shaped wheeling disk structure, including the wheel disc 2 being fixed on bicycle middle shaft 1, wheel disc
2 be in anti-D fonts, is slided in the described outer rim of wheel disc 2 and is provided with sliding chain 3, is provided with described sliding chain 3 and bicycle chain
The tooth 5 that bar 4 coordinates, is provided with telescopic pedal bar on described axis 1, during the inner connection of described telescopic pedal bar is described
Axle 1, the middle part of described telescopic pedal bar connect described sliding chain 3 by connecting rod 6, and the outer end of described telescopic pedal bar connects
Connect pedal 7.
The outer rim of wheel disc 2 is provided with sliding groove, and both sides are provided with bearing in described sliding groove, and described sliding chain 3 is slided embedding
Between two side bearings in described sliding groove.
Telescopic pedal bar includes the interior bar 8 of connection axis 1, and described 8 outer Slideslip of interior bar has outer loop bar 9, described company
Bar 6 is arranged on outer loop bar 9.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
