Description of the Invention: [Technical Field of the Invention] The present invention is a kind of "seat structure", especially "the structure of the toothed seat of the bicycle after the flower valley", and the ribs of the grain-for-money The positioning ribs are so high that the area is too high, and the ridges (10) are smashed by the pure transmission, and the escaping sleeve is formed by _ body molding, which simplifies the assembly process and saves manufacturing costs. • [Prior Art] Press 'To make the bicycle's sprocket seat have both lightweight and structural strength, generally ” a large eve made of 335 gold, but the age of the toothed disc seat, mostly hardness It is made of relatively high height and material rhyme. It is also used in the process of moving the toothed disc holder. The capacity of the stalk is purely recorded, and the service life of the lower seat is studied. As shown in Fig. 7, Fig. 8, and Fig. 9, the sprocket holder is disposed on one side of the flower valley, and includes: a sprocket holder (5 〇)' and is disposed on the spur a protective piece (60) on the seat (5), wherein the sprocket seat (50) is a tubular body and made of an alloy material, and a plurality of ribs are provided on the outer circumference equidistant ring (51). And a plurality of ribs (10), and a groove (53) is formed at the break of the rib (52) for sharply opposing the rib (52). a ridge (6 〇), and a reinforcing rib is formed (7 〇 y, then a u/disk holder (50) embedded with a protective sheet ((9)) is assembled in the sprocket set, the sprocket set (10)) Inner circumference. Further, there are a plurality of embedded grooves (not shown) opposite to the positioning ribs (5) of the spur base (5) and the reinforcing ribs (7). 201215537 Looking at the above-mentioned conventional structure is not difficult to find that there are still some shortcomings. The main reasons are as follows: (-) The conventional toothed seat structure, because the protective piece (6G) is only partially embedded in the ridge ( 52) The gully (53), therefore, its structural strength is insufficient, and there is a loose tax, warped shackles; (2) the conventional sprocket seat structure, because its protective sheet (6 〇) must be embedded in the piece by piece The groove (53) of the strip (52), therefore, the assembly procedure is cumbersome and time consuming, thereby increasing the production cost thereof, and it is also easy to cause errors in the successive installation process, so that the guard piece (60) and the toothed cliff (50) It is difficult to close and conform to the wear; (3) The conventional sprocket seat knot # structure, because the sprocket seat (5 〇) is attached with a protective sheet (6 〇), so that the quality of the sprocket seat (10) is relatively large, It is impossible to combine the weight of the structure. In view of this, the creators have been engaged in the manufacturing development and design experience of related products for many years, and after the detailed design and careful evaluation of the above objectives, they have finally achieved a practical and practical creation. SUMMARY OF THE INVENTION The technical problem to be solved is: Lu (1) The conventional toothed disc seat structure, because the protective piece is only partially embedded in the groove of the ridge, the structural strength is insufficient, and the structure is loose and light. The song of the song. (2) The conventional toothed disc seat structure, because its protective sheet has to be embedded in the groove of the ridge, one by one, and the assembly procedure is cumbersome and time consuming, thereby increasing the production cost and easily causing errors in the successive installation process. Therefore, it is difficult for the guard piece and the sprocket seat to be in close contact with each other. [2] (2) The conventional sprocket seat structure has a relatively large mass of the sprocket seat due to the addition of a guard piece to the sprocket seat, so that the structure cannot be lightweight. 4 201215537 Technical characteristics of the problem-solving: μ = the invention is to provide the structure of the toothed disc seat of the bicycle rear hub, which is mainly composed of; the side of the chemical element is composed of a sewing seat and a protective bushing, wherein , π Ή ° ° New Zealand made 'and the inside - cylindrical body, and equidistantly looped into the positioning rib on the outer circumference and then the outer edge of the (4) connecting wire ends (4) into a load, 'also in the inner circumference : It has a threaded section, and the protective bushing is made of a thin body of high rigidity material and is made by -H molding. Its shape is commensurate with the bell seat, and the inner circumference is concavely matched with multiple wires. With the pure red New Zealand _ pair and tightly-incorporated into the Yaka to stop at the seat of the seat, and then practice the groove outside the lining to form a relatively prominent reinforcement rib, thereby taking advantage of the 剌 种 - kind of bicycle rear flower valley seat structure . Compared with the effects of the prior art: (1) The structure of the toothed disc seat of the bicycle rear flower fc of the present invention, since the sprocket seat is fixed for 1 month, the rib of the protective cover is provided, so that the rigidity of the positioning rib is complicated. The call to mention the 'Tennan' to make the positioning ribs wear by the gear plate transmission. (1) The structure of the toothed disc seat of the bicycle behind the bicycle of the present invention, because the protective sheath is formed by the f forming method, and the reinforcing rib and the positioning rib of the sprocket seat are in close proximity to the formula 2 (4) (4) lion secret俾 提高 提高 提高 提高 提高 提高 提高 提高 提高 提高 提高 提高 提高 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 (3) The wire reading structure of the bicycle after the hairpin is positioned by the _ pedestal, and the cover is covered with the reinforcing rib of the protective bushing, so that the rigidity of the contact rib contact area is improved, and the rib can be improved Torque force, Kawasaki does not fall [s] 201215537 Low-toothed disk seat can carry the upper limit of the torque force, reduce the number of positioning ribs, and achieve the structural weight reduction requirements of the toothed seat. [Embodiment] In order to enable the reviewing committee to have a more in-depth understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [detailed description of the drawings] as follows: First, please refer to Figure 1 and Figure 2 is a view of the figure shown in Figure 3. The structure of the bicycle rear hub is composed of the main county of the silky m (10) ♦ and the protective bushing (20). The disc base (10) is made of a sinter alloy shell and is a - cylindrical body and is provided with a plurality of positioning ribs (11) on the outer circumference of the equidistant ring, and then protrudes from the periphery of the adjacent connecting hub end. There is a retaining edge (12), and a threaded section (13) is formed on the inner circumference. The protective bushing (2〇) is a thin tube body of a high-rigidity material (such as a ferroalloy material), and is integrally formed. The shape is commensurate with the spur base (10) and the inner peripheral edge is recessed with a plurality of opposite grooves (21)' to oppose the positioning rib (1) of the sprocket seat (1 〇) and is embedded in a tight fit manner. _Into the cover f is there, and is locked in the #盘盘(1)) 麟 (o and then on the periphery of the drum groove (21) to form a relatively protruding reinforcing rib (22) In actual use, please see the figure 4 and 5, the sprocket holder U0) is used with the above-mentioned sprocket (9) and the locking member (the sringe (30) The shape of the shaft hole (31) is opposite to the reinforcing rib (22) of the protective bushing (2〇) and is transmitted by the setting of the locking member (4〇). The threaded slave (13), which is locked to the sprocket seat (3) by the threaded section (6), will cause the sprocket seat (10) to have its positioning rib (] ι) when the sprocket wheel (3 〇) is rotated. (5) 6 201215537 The side of the belt is subjected to a torque force.
