[Prior Art] A conventional rim group such as a bicycle wheel set generally uses a wheel light steel wire to combine a flower hub provided inside and outside with a rim, and in recent years, the rim » again. Ten has gradually focused on strengthening the structure, reducing the weight, and beautifying the appearance of ... 10 ... and other subjects, and the inventors are committed to research to achieve the above objectives. As shown in FIG. 1 and FIG. 2, a conventional rim 1 includes two left and right spaced ring I side walls 11 (only one annular side wall U is shown in FIG. 1), and the annular side walls u are connected and spaced inside and outside. An annular inner portion I 12 and an annular outer wall 13 are provided. The annular inner wall 12 is provided with a plurality of spaced apart mountings & 121 along the circumference of the center, and a plurality of thin sections 122 formed between the two adjacent mounting sections ΐ2i, respectively. Each mounting section 121 has a set of apertures ΐ2ι for direct locking of a wire. Each of the thin sections 122 is milled and recessed radially outward. It can be seen from the above that the conventional rim rim is provided with a thin section 122 spaced apart on the annular inner wall 12, although the design of the thin section 122 can make the rim lighter, to reduce the rim Weight and inertia. However, from the material mechanics point of view, it can be seen that in the central circumferential part of the ring (four) 12, the flexibility is large and the tensile force is small, while the wheel i is concentrated here to set the hole 121 and thin. In the segment 122, when the assembled wheel is assembled, the peripheral portion of the sleeve 4 hole 121 is often easily deformed by the strong pulling force of the steel wire 14, so that the wire 14 is difficult to maintain the tensioned structure and is in a slack state. Will result in a reduction in the quality of the rim. In addition, the design of the thinning section 122 will result in a weaker central circumferential portion which is inherently low in strength, resulting in a small strength of the rim at a relatively short distance, and the overall rim The strength of the rim is greatly reduced. Therefore, it is necessary to calculate the tension and strength required for the rim more precisely, that is, the number of wires 14 installed, the distance between two adjacent ferrule holes, and the thin section 122 The degree of thinness, so it takes a lot of effort 10 to get a proper design, so the rim 1 structure is less than ideal. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a split-side pull-type lightweight rim that has both high strength and light weight efficiency and that has fewer design considerations. 15 ^ month - seed side pull-type lightweight rim, can be erected by a number of steel wire and a number of matching wire locks on the outside of the flower, and contains two left and right spaced annular side walls, - ring inside f , and two ring corners. Each of the % shaped side walls has a radially inner end edge adjacent the hub. The annular inner wall 20 surrounds the periphery of the U and is located at a radially inner end edge of the material ring (4). The annular corners respectively connect the radially inner end edges of the annular side walls and the left and right sides of the %-shaped inner wall, each annular corner has a plurality of phase-to-phase segments, and the plurality of components are connected between the two adjacent mounting segments. Extending through the mounting sections along the ring and extending to the surface of the thinned sections: ― ^ a* τ 々 f 又 又 又 又 又 表面 ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ 1322094 Installed ferrule hole, each-cut thin section is inclined by the inner side of the Huadun to the outside and to the opposite side of the annular inverted wall, and! The ferrules are spaced apart from one another and have a long/angled ridge. And the splicing segments are also spaced apart from each other by a distance of 5 10 15 . The effect of the invention is that the ring-shaped corners of each ring-shaped corner are respectively penetrated along the ring, and the thinning is formed between the two adjacent mounting segments. In the case where the installation section is thick and has high strength, (4) multiple parts, the overall weight of the rim is reduced to reduce the inertia, so that the light weight effect can be achieved and the design conditions are relatively simple. The above and other technical contents, features and effects of the present invention will become apparent from the following detailed description of the preferred embodiments. As shown in FIG. 3, FIG. 4 and FIG. 5, the preferred embodiment of the split-side pull-type lightweight rim of the present invention is provided by a plurality of steel wires 2 and a number of matched steel wire locks 3 On the periphery of the flower hub 4 on the center line 41, each of the wires 2 has a hook end 21 for hooking on the flower hub 4, and a screw end 22 opposite to the hook end 21. The wire lock head 3 has a catching section 31' for locking the threaded end 22 and a latching section 32 which is opposite to the engaging section 31 and which projects radially. The rim is integrally formed of metal and comprises: two annular side walls 5, an annular inner wall 6, two annular corners 7, and an annular outer wall 8. The annular side walls 5 are spaced around the center line 41 at right and left intervals, and each of the sash-shaped side walls 5 has a radially inner end edge 51 1 adjacent to the center line 4 、 and a radially inner end edge 51 opposite thereto. The radially outer end edge 52, and a plurality of side perforations 53 spaced apart and left 20 right. A perforation 53 on each side allows the wire lock 3 to be inserted through. The side perforations 53 located on the two annular side walls 5 are angularly offset. The annular inner wall 6 surrounds the periphery of the hub 4 and is located between the radially inner end edges 51 of the annular side walls 5. 10, as shown in FIG. 6, the annular corners 7 respectively connect the radially inner end edge 51 of the annular side wall 5 with the left and right sides of the annular inner wall 6, and each of the annular corners 7 has a plurality of phase (five) partitions. 71. A plurality of thin sections 72 respectively connected between two adjacent women's clothing sections 71, and ring holes extending through the mounting sections and extending to the surface of the thinning sections 72. The overall section thickness of the corners 7 is greater than the overall section thickness ' of the annular inner wall 62 and the per-cut section 72 is inclined from a radially inner side toward a radially outer side and to the opposite side of the annular side wall 5 so that the thin section The overall section thickness of 72 is smaller than the overall section thickness of the mounting section 71. 15 20 The mounting sections 71 are disposed on the two annular corners 7 in a mutually offset manner, and each of the mounting sections 71 has a sleeve hole 7U extending through the inner and outer passages and communicating with the ring holes 73 for mounting the wire lock head 3. Each of the ferrule holes 7 ι corresponds to the side through holes 53 via the annular inner wall 62. And by the centering of the annular hole 73, each of the mounting sections 71 is a hollow portion having a double wall. Each of the thin sections 72 has a flat section a located at the center and recessed toward the outer side of the (four) outer side, and two are respectively adjacent to the sleeve hole 7 by the erroneous flat section 721 The μ ^ ^ Α side is 722 whose ice is gradually decreasing. The cross-sectional thickness of the flat portion 721 is smaller than the thickness of the wear of the arc portion 722. Of course, the surface of the thin section 2 can also be more deeply recessed than the annular hole 73 or the silver hole 73 (see Fig. 7). 7 In manufacturing, the rim is formed with a ring hole 73 directly in the extrusion molding, and after the segment is joined into a ring shape and subjected to anodization, and then spaced radially on the inner side of the annular corner 隅7 by a milling machine. The sharp cut is formed to form a cut 72 分别, and the annular outer wall 8 is disposed outside the one end of the annular inner wall 6 away from the center line, and is connected at the outer side of the side annular hole 53 to be shared with the annular side wall 5 A tire mounting space 81 having a U-shaped cross section and an opening facing outward is defined for mounting a tire 9. The tire skirting space Η is not in communication with the side perforations 53. When assembling, the wire lock head 3 is inserted into the side through hole 53 so that the wire lock head is directly inserted into the corresponding sleeve hole 711, so that the engaging portion ^ is pierced out of the sleeve hole 711, and the click portion 32 is locked. Mounting section 71, and hooking the hook end 21 of the steel wire 2 to the flower raft 4, and then screwing the screw end end of the steel wire 2 with the engaging section 3丨, so that the steel wire 2 is subjected to tension and tensioning the flower valley 4 with rims. Finally, the tire 9 is placed in the tire installation space 8 , and after the space W is inflated, the two ends of the tire 9 are positioned on the diameter (four) edge 1 . From the above, the present invention has the following advantages which are better than the conventional ones: The strength of the rim can be maintained as a whole: the present invention is provided on the two sides of the annular corner 隅7 which are thicker and more flexible, and the ferrules 711 are interposed in a staggered manner to increase the spacing of the arranging holes 711 to disperse the pulling force. Therefore, the circumference of the sleeve hole 711 is less affected by the tensile deformation, so that the tension of the steel wire 2 can be maintained: the thinner slaves 72 are also arranged at intervals on the annular corner 隅7 and the ring angle 每 per side. The thin section 72 on the seventh side will be reinforced with the mounting sections 71 on the corners 1322094 of the other side, so that other considerations on the strength design conditions can be simplified or reduced, so that the overall rim of the rim is not subjected to tensile deformation. The structural design is better. Second, lighter weight: the invention is lifted before affecting the strength, and is provided with a % hole 73 and a thin section 72, so that the overall weight of the rim is reduced, the rim inertia can be reduced, and the weight reduction effect can be achieved. . Ίο Second, more beautiful: As shown in Figure 4, the rim is manufactured by silver-white aluminum alloy extrusion, and after cutting and bending into a circular ring, it will process the hole and then do it. Anti-oxidation anodizing treatment to coat the surface of the aluminum alloy with an ink black anode film, and the present invention further cuts the thin section 72 in a staggered manner on the two % angles 内侧7 on the inner side of the rim. Relatively cutting off the black black anode film and exposing the silver-white smelting alloy, and then showing a two-color collocation with a distinct interval, it can improve the variability of the overall color of the rim's appearance and aesthetic appearance. The light-weight rim of the split-side pull-up type does maintain the overall strength of the rim, and it is quantified, and the effect of aesthetics, etc., is more innovative for the industry. From the above description, it can be seen that the rim has a rim. It is not subject to tensile deformation, and it can be lightened before being able to maintain high strength. Therefore, the present invention is not only an unprecedented scorpion/T returner, but only the present invention. However, it is not intended to limit the scope of the invention to the extent that the equivalent changes and modifications of the vapor th ^ π according to the scope of the invention and the contents of the invention are still within the scope of the invention.
