Abstract
A kind of bicycle use single layer car rim.It is the cast structural that the cross section being made up of top plate and biside plate is U-shaped, is used to set tire in U-shaped space, the outer end edges of each side plate extend internally and form a snap ring.Bicycle use single layer car rim provided by the utility model is one snap ring to extend internally of formation on the side plate of the single layer car rim of prior art, constrains rubber tyre using the snap ring, therefore can effectively prevent rim from being separated each other with rubber tyre.Further, since there is no excessive change to the single layer car rim structure of prior art, therefore it will not excessively increase production cost, and installation process does not change.
Description
Technical field
The utility model belongs to attachments of a bicycle technical field, particularly a kind of bicycle use single layer car rim.
Background technology
Bicycle is also known as bicycle or bicycle, and it is a kind of green vehicles using foot pedal as power,
Mainly include 25 parts such as terraced, the rear clothes hanger of vehicle frame, wheel, foot-operated, brake, chain, middle branch.Wherein wheel mainly by rim,
Spoke, tire, axletree are formed.Rim is broadly divided into two kinds of individual layer and bilayer.Fig. 1 is a kind of currently used single layer car rim main view
Figure.Fig. 2 is the rim transverse cross shown in Fig. 1.As shown in Figure 1 and Figure 2, this rim is made up of top plate 1 and biside plate 2
Cross section be U-shaped cast structural, be used in U-shaped space set tire.But the single layer car rim of this prior art is present
Following point：When bicycle uses solid tire, this wheel dispatch from the factory before be by solid tire by super glue
It is attached in the U-shaped space on rim, when bicyclist's high speed steering, because side plate 2 is straight panel, does not constrain thereon, therefore
Solid tire on front-wheel is easy to knocking over phenomenon occur, and this phenomenon is more during summer high temperature, because rubber for tire
With certain contraction extension rate, rim will cover incessantly this tire when more than certain limit.And filled when bicycle uses
During gas rubber tyre, in the case of tyre inflating amount deficiency, therefore rim can also separate with tire.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of bicycle use single layer car rim.
In order to achieve the above object, bicycle use single layer car rim provided by the utility model is made up of top plate and biside plate
Cross section be U-shaped cast structural, be used to setting tire in U-shaped space, the outer end edges of each side plate extend internally and
Form a snap ring.
Described snap ring is integrally formed with top plate and biside plate.
The outer end edges of described snap ring are in circular arc along corner.
Bicycle use single layer car rim provided by the utility model is to form one on the side plate of the single layer car rim of prior art
The individual snap ring to extend internally, rubber tyre is constrained using the snap ring, thus can effectively prevent rim and rubber tyre that
This separation.Further, since there is no excessive change to the single layer car rim structure of prior art, therefore it will not excessively increase and be produced into
This, and installation process does not change.
Brief description of the drawings
Fig. 1 is a kind of currently used single layer car rim front view.
Fig. 2 is the single layer car rim transverse cross shown in Fig. 1.
Fig. 3 is structural representation when bicycle use single layer car rim provided by the utility model is splitted at diameter.
Embodiment
Bicycle use single layer car rim provided by the utility model is carried out specifically with specific embodiment below in conjunction with the accompanying drawings
It is bright.Identical drawing reference numeral is used with prior art identical part.
As shown in figure 3, bicycle use single layer car rim provided by the utility model is the horizontal stroke being made up of top plate 1 and biside plate 2
Section is the cast structural of U-shaped, is used to set tire in U-shaped space, the outer end edges of each side plate 2 extend internally and formed
One snap ring 3.
Described snap ring 3 is integrally formed with top plate 1 and biside plate 2.
The outer end edges of described snap ring 3 are in circular arc along corner, to prevent from damaging rubber tyre.
The assembling of bicycle use single layer car rim provided by the utility model and solid tire or aerated rubber tyre
The same prior art of journey, therefore no longer repeat here.
In use, because the outer end edges of side plate 2 are formed with a snap ring 3, thus to solid tire or
Aerated rubber tyre forms constraint and tightly blocks the latter, therefore rim also will not be with tire point when summer high temperature
From.
