Abstract
A kind of aluminum alloy bicycle rim, including wheel rim（1）, wheel rim（1）Profile be U-shaped, wheel rim（1）U-shaped two sides（2）Outer wall be directly to side, in the wheel rim for U-shaped（1）U-shaped two sides（2）The projection of two dome shapes in left and right is formed on the inwall of top（3）, two sides of U-shaped（2）Inwall be followed successively by projection from top to bottom（3）, vertical section in first（4）, segmental arc（5）With second in vertical section（6）, vertical section in first（4）With second in vertical section（6）It is vertical plane.It is simple in construction, material saving, the U-shaped both sides of bicycle rim directly is designed as directly increasing to side to the load-carrying properties of bicycle rim, while bicycle spoke does not contact with bicycle tube, increases the service life of the inner tube of a tyre.
Description
Technical field：
Aluminium alloy casting technology field is the utility model is related to, more specifically to a kind of aluminium alloy car of bicycle
Circle.
Background technology：
Existing aluminum alloy bicycle rim is general in design, is U-shaped by rim design, simply its U-shaped both sides is oblique
Xiang Bian, its weak point are：1st, the U-shaped weight not enough saved material, can so increase rim with oblique side.2nd, due to voluntarily
The weight of car rim is usually fixed number, if U-shaped both sides are designed as oblique, can reduce the thickness of rim other parts,
So that the load-carrying properties of whole rim reduce.3rd, some rim bicycle inner rings are directly born against on spoke cap, are so easily triggered
Bicycle tube damages.
Utility model content：
The purpose of this utility model and provides a kind of aluminum alloy bicycle rim aiming at the deficiency of prior art, it
It is simple in construction, material saving, directly the U-shaped both sides of bicycle rim are designed as directly to increase holding for bicycle rim to side
Performance is carried, while bicycle spoke does not contact with bicycle tube, increases the service life of the inner tube of a tyre.
Technology solution of the present utility model is as follows：
A kind of aluminum alloy bicycle rim, including wheel rim, the profile of wheel rim are U-shaped, the outer wall on two sides of the U-shaped of wheel rim
Directly to side, to form the projection of two dome shapes in left and right on two sides top inwall of the U-shaped of the wheel rim for U-shaped, U-shaped
The inwall on two sides is followed successively by raised, vertical section in first from top to bottom, vertical section in segmental arc and second, vertical section in first
With second in vertical section be vertical plane.
Vertical section forms U-type groove in wheel rim in described two second, and bicycle spoke cap is placed in wheel rim in U-type groove, from
The driving inner tube of a tyre is pressed on segmental arc.
The entity part of wheel rim corresponding to two segmental arcs forms enhanced type entity, is formed on enhanced type entity
The through hole of the degree of lip-rounding.
The beneficial effects of the utility model are：
It is simple in construction, material saving, directly is designed as to side directly increasing voluntarily by the U-shaped both sides of bicycle rim
The load-carrying properties of car rim, while bicycle spoke does not contact with bicycle tube, increases the service life of the inner tube of a tyre.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
In figure：1st, wheel rim；2nd, two sides of U-shaped；3rd, it is raised；4th, vertical section in first；5th, segmental arc；6th, it is vertical in second
Section；61st, U-type groove in wheel rim；7th, enhanced type entity；8th, through hole.
Embodiment：
Embodiment：As shown in Figure 1, a kind of aluminum alloy bicycle rim, including wheel rim 1, the profile of wheel rim 1 are U-shaped, wheel rim
Two of 1 U-shaped while 2 outer wall for directly to while, form a left side on the top inwall of two sides 2 of the U-shaped of the wheel rim 1 for U-shaped
The projection 3 of right two dome shapes, the inwall on two sides 2 of U-shaped are followed successively by vertical section 4, arc in projection 3, first from top to bottom
Vertical section 6 in section 5 and second, vertical section 6 is vertical plane in vertical section 4 and second in first.
Vertical section 6 forms U-type groove 61 in wheel rim in described two second, and bicycle spoke cap is placed in U-type groove 61 in wheel rim
In, bicycle tube is pressed on segmental arc 5.
The entity part of wheel rim 1 corresponding to two segmental arcs 5 forms enhanced type entity 7, on enhanced type entity 7 into
Type has the through hole 8 of the degree of lip-rounding.
Operation principle：The utility model by two of the U-shaped of wheel rim 1 while 2 outer wall be designed as directly to while, such structure
Most material saving, while can allow and enhanced type entity 7 is formed on wheel rim, enhanced type entity 7 can increase the load-carrying properties of bicycle wheel rim.
Bicycle spoke cap is placed in wheel rim in U-type groove 61, and bicycle spoke cap will not contact with bicycle tube, so as to protect voluntarily
In-car tire, increase the service life of bicycle tube.The through hole 8 of the degree of lip-rounding can not influence the same of bicycle rim load-carrying properties
When, save material.
