New description: [New technical field] This creation is mainly about a chain, especially a chain used for bicycles. [Prior Art] According to the conventional sprocket (50), it is mounted on a bicycle as shown in the sixth figure. 'It is surrounded by a chain and engages with each other to be driven by a chain or to drive a chain'. The chain plate (50) is mainly provided with a metal sheet body (51)' and in order to make the chain plate (50) sufficiently rigid for use, an injection molding is formed on each side of the metal sheet body (51). The plastic disk body is used to form the required chain plate (50); however, although the existing chain plate (50) can provide a function of transmission, the two plastic disk bodies (52) are coated on the metal plate body (51). The outer surface of the plastic is poorly adhered to the metal because of the adhesion of the plastic to the metal. Therefore, when the chain plate (50) is used for a long time, the plastic disk body (52) is likely to occur from the metal body (51). In the case of falling off, there are improvements. [New content] Therefore, in view of the existing chain structure and manufacturing deficiencies and lacks, the creation has finally evolved to improve the original creation. - The main purpose of this creation is to provide a bicycle chain plate, which can be misplaced by the fine structure of the structure, so that the two plates can be firmly attached to both sides of the metal piece, so that the bicycle chain plate is formed - The purpose of streamlining and solid combination. 3 In order to achieve the above objectives, the present invention provides a bicycle chain plate, which comprises a body and two disc bodies, wherein: the system is made of a ring-shaped piece made of metal, and the body is attached to the outer circumference of the body. Forming a plurality of sprocket teeth 'through the center of the body is provided with a crank hole, the body is provided with a plurality of perforations between the crankshaft hole and the sprocket; and two disc systems are respectively formed on both sides of the body, wherein each The outer periphery of the disc body has a wavy structure and the two disc bodies are respectively provided at the center with through holes communicating with the crankshaft holes of the main body, and the two disc systems are adhered to each other through the perforations of the main body. Each of the perforations of the body is wrapped in the two bodies. Further, each of the perforations is provided on the body in a manner of being arranged in a wrong manner. Further, the body is provided with a hole having a small hole diameter near the sprocket, and the system is provided with a hole having a large hole diameter at the periphery of the crank hole. Preferably, the crankshaft bore is a multi-claw crankshaft bore. Preferably, the outer periphery of each of the disc bodies has a continuous undulating structure 〇 _ Preferably, the outer peripheral edges of the respective disc bodies are in the form of a continuous wave-like structure. Preferably, the two disc systems are plastic discs formed on both sides of the body by injection molding. Preferably, the two disc systems are a composite disc formed on either side of the body. By the above technical means, the bicycle chain plate of the present invention is formed by a plurality of perforations formed between the key teeth of the main body and the holes, so that the two disc bodies can be adhered together through the respective perforations, not only the two disc bodies can be It is fixedly attached to the sides of the body 7738, and can be placed on the body with a plurality of perforations. The weight of the body is reduced, and the structure is simplified. The bicycle chain is ^, ° σ [Embodiment] This creation mainly provides a bicycle chain plate. Please refer to the first to fifth figures. When you see it, you can see that the chain system and the matching-key bar of this creation use the main system. - a body (1Q' 1Q') and two disk bodies (10), wherein the body (1G '1G,) is an annular piece made of - metal, the body (10 ' 1G ) is formed on the outer circumference A plurality of sprocket teeth (1), at the center of the body (10), 1 〇, are provided with a crank hole (12' 12,) combined with a bicycle pedal (3 〇), wherein the crankshaft hole. 2, the system can be a round hole or a slightly cross-shaped hole, which in turn drives the chain state to drive the transmission 'the body (10,10,) between the crankshaft hole (12,12,) and the sprocket (1)) There are a plurality of perforations (13, 13'), wherein the perforations (13, 13,) are arranged on the body (1〇, 1〇) in a wrong arrangement, preferably, the body (10) , 10') near the key (1), 1V) is provided with a small aperture (13 ' 13 ) ' and the body (1 〇, 1 〇,) is attached to the periphery of the crankshaft hole (12, 12) Preferably, the crankshaft hole (12'12') is a multi-claw crankshaft hole (12,); and the two disk bodies (20) are respectively - a plastic disk formed on both sides of the body (1〇, 1 〇) by injection molding or a disk composed of a composite material, wherein the outer circumference of each disk body (20) is continuous or continuous The wavy structure, the two disc bodies (2 〇) are respectively provided with a through hole (21) communicating with the crankshaft holes (12, 12,) of the body (1 〇, 1 〇 ') at the center, and the two disc bodies 2)) through the perforations (13, 13') of the 5 M377386 k body (10, 1 〇) and adhered to each other, so that the perforations of the body (1〇, 10') 〇 3, 13,) Covered in two discs (20). The bicycle chain of the present invention is mainly formed by forming a plurality of perforations (13, 13) between the sprocket (11, 11) of the body (10, 10,) and the crank hole (12, 12,). The two disc bodies (2〇) can be adhered together through the perforations (a, 彳3,), and the two disc bodies (20) can be stably attached to the two bodies (1〇, 10). Side, and by means of a plurality of perforations (13 '13') on the body (彳〇, 彳〇,), the weight of the body (1〇, 1〇,) is greatly reduced, and then the structure is reduced. And can be firmly combined with the bicycle chain. [Simple description of the drawing] The first picture is a side view of the appearance of the creation.
