Abstract
A kind of bicycle use bilayer rim.It is the cast structural being made up of ring-shaped outer layer top plate, internal layer top plate and biside plate, wherein outer layer top plate and internal layer top plate be arranged in parallel, biside plate is connected to the both ends of outer layer top plate and internal layer top plate simultaneously, is used to set tire in the U-shaped space surrounded between internal layer top plate and biside plate；The outer end edges of each side plate extend internally and form a snap ring.Bicycle use bilayer rim provided by the utility model is one snap ring to extend internally of formation on the side plate of the double-deck 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 double-decker coil structures 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 bilayer 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 double-deck rim main view
Figure.Fig. 2 is the double-deck rim transverse cross shown in Fig. 1.As shown in Figure 1 and Figure 2, this rim be by ring-shaped outer layer top plate 1,
The cast structural that internal layer top plate 2 and biside plate 3 are formed, wherein outer layer top plate 1 and internal layer top plate 2 be arranged in parallel, and biside plate 3 is simultaneously
The both ends of outer layer top plate 1 and internal layer top plate 2 are connected to, are used to set in the U-shaped space surrounded between internal layer top plate 2 and biside plate 3
Tire.But row problem in the presence of the double-deck rim of this prior art：When bicycle uses solid tire, this wheel
It is that solid tire is attached in the U-shaped space on rim by super glue before dispatching from the factory, when bicyclist's high speed steering, by
It is straight panel in side plate 3, does not constrain thereon, therefore the solid tire on front-wheel is easy to knocking over phenomenon occur, summer is high
This phenomenon is more when warm, because rubber for tire has certain contraction extension rate, rim will when more than certain limit
Cover does not live this tire.And when bicycle uses aerated rubber tyre, in the case of tyre inflating amount deficiency, rim also can
Therefore separated 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 bilayer rim.
In order to achieve the above object, bicycle use bilayer rim provided by the utility model is by ring-shaped outer layer top plate, interior
The cast structural that layer top plate and biside plate are formed, wherein outer layer top plate and internal layer top plate are be arranged in parallel, and biside plate is connected to simultaneously
The both ends of outer layer top plate and internal layer top plate, the U-shaped space surrounded between internal layer top plate and biside plate is interior to be used to set tire；Each side
The outer end edges of plate extend internally and form a snap ring.
Described snap ring is integrally formed with outer layer top plate, internal layer top plate and biside plate.
The outer end edges of described snap ring are in circular arc along corner.
Bicycle use bilayer rim provided by the utility model is to form one on the side plate of the double-deck 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 double-decker coil structures 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 double-deck rim front view.
Fig. 2 is the double-deck rim transverse cross shown in Fig. 1.
Fig. 3 is structural representation when bicycle use bilayer rim provided by the utility model is splitted at diameter.
Embodiment
Bicycle use bilayer 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 bilayer rim provided by the utility model is by ring-shaped outer layer top plate 1, internal layer top plate 2
The cast structural formed with biside plate 3, wherein outer layer top plate 1 and internal layer top plate 2 be arranged in parallel, and biside plate 3 is connected to outer simultaneously
The both ends of layer top plate 1 and internal layer top plate 2, the U-shaped space surrounded between internal layer top plate 2 and biside plate 3 is interior to be used to set tire；Each
The outer end edges of side plate 3 extend internally and form a snap ring 4.
Described snap ring 4 is integrally formed with outer layer top plate 1, internal layer top plate 2 and biside plate 3.
The outer end edges of described snap ring 4 are in circular arc along corner, to prevent from damaging rubber tyre.
The assembling of bicycle use bilayer 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 3 are formed with a snap ring 4, 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.
