(3) novel content:
Main purpose of the present utility model is at the composite rim structure that a kind of bicycle and similar car are provided, and makes its scientific structure, and it is good to reach manufacturability, low cost of manufacture, and light weight and structural strength are good, effects such as long service life.
The composite rim structure of a kind of bicycle of the utility model and similar car, it is characterized in that: by the made hollow wheel rim of composite, its outer diametric plane is the arc concave surface, be used for installing tire, link with steel bar between aperture surface and flower-drum, the hollow wheel rim internal face of aperture surface and steel bar joint is provided with comparatively outstanding reinforcing block, make it bigger bearing stress and can support steel bar, on each reinforcing block, be provided with a radial perforation, penetrate in the wheel rim for the perforation of steel bar tool screw tooth end on reinforcing block, the slotted eye that is provided with by the corresponding place of the external diameter face screw tooth end that stretches into a nut and steel bar is spirally connected again.
Wherein, the hollow inner side of wheel rim can be packed to composite porous.
Wherein, what wheel rim hollow inner side is provided with a ring reinforced ribs near outer diametric plane side, makes wheel rim more hard.
Wherein, what wheel rim hollow inner side is provided with a bit of reinforced ribs near aperture surface side and corresponding reinforcing block place, makes wheel rim more hard.
Wherein, this composite porous foam that can be.
Wherein, perforation can be one-body molded with middle empty talk circle on making.
From the above, the composite rim structure of a kind of bicycle of the utility model and similar car, its principal character is:
The middle empty talk circle of making by composite, its outer diametric plane is the arc concave surface, be used for installing tire, aperture surface is used for combining with steel bar, the wheel rim internal face that engages with steel bar at aperture surface is provided with comparatively outstanding reinforcing block, make this position have bigger bearing stress and can support steel bar, each reinforcing block is provided with a radial perforation, connect flower-drum for steel bar one end, another tool screw tooth end can penetrate in the wheel rim in the perforation on reinforcing block, and the slotted eye that is provided with by the corresponding place of the external diameter face screw tooth end that stretches into a nut and steel bar is spirally connected again.The mat wheel rim only has reinforcing block at the aperture surface inwall that links the steel bar place, and to promote the bearing stress of this position, general thickness is then kept at other positions, the material cost when saving manufacturing with this and the effect of tool light weight.
The composite rim structure of a kind of bicycle of the utility model and similar car, its advantage is: scientific structure, manufacturability is good, low cost of manufacture, light weight and structural strength are good, long service life.

(5) specific embodiment:
See also shown in Fig. 4～6, by the made middle empty talk circle 10 of composite, its outer diametric plane 11 is a cancave cambered surface, is used for installing tire, and aperture surface 12 is used for linking with steel bar 13.Aperture surface 12 is provided with comparatively outstanding reinforcing block 121 with wheel rim 10 internal faces of steel bar 13 joints, reinforcing block 121 is provided with radial perforation 120 (shown in Fig. 4,5, perforation 120 can be one-body molded with hollow wheel rim 10 on making, improve known disappearance of boring sky in addition with instrument), connect flower-drum (not showing what figure) for steel bar 13 1 ends, another tool screw tooth end 120 penetrates in wheel rim 10 aperture surfaces 12 through boring a hole, and the screw tooth end that stretches into a nut 111 and steel bar 13 by the set slotted eye 110 in outer diametric plane 11 corresponding positions is spirally connected again; Diametric plane 11 places are provided with a ring reinforced ribs 14 outside wheel rim 10 hollow inner side are near in addition, then are being provided with a bit of reinforced ribs 15 at every corresponding reinforcing block 121 places near aperture surface 12 sides.Reinforced ribs the 14, the 15th is set, make wheel rim 10 meet with stresses need be bigger the position can be more hard, because of bear for a long time external force do not cause the distortion.
The utility model is for strengthening the stress of composite wheel rim 10, that wheel rim 10 also can be put in wheel rim 10 when moulding is composite porous 20 (for example: foam), as shown in Figure 7.
In sum, the utility model only increases thickness at the internal face that aperture surface 12 engages with steel bar 13, so the total quality of more known wheel rim alleviates, the manufactured materials cost also significantly reduces, and novel structure is significantly improved than known wheel rim.
