New Description: [The new type of technical field is mainly related to a type of chain, especially one used for bicycle chain prior art. Generally, the existing chain system is installed on a bicycle. The chain encloses the half and engages with each other to be driven or driven by the chain. In order to make the chain rigid enough for use, the existing keyboard mainly forms the required keyboard by processing the metal material. However, by means of metal processing, although the keyboard can provide sufficient rigidity, the metal processing method is not only time-consuming, high in manufacturing cost and heavy in weight, and the method has (4) lowering the chain plate under the full rigidity condition. The system has been improved by cost and weight. [New content] Because: This creation has been developed in view of the existing chain structure and manufacturing deficiencies, as well as the lack of trial and research, and finally developed a kind of creation that can improve both existing and missing. The main purpose of this creation is to make a bicycle keyboard that can be molded by body-molding, which has rigidity and minus f, and is constructed of a chain plate - which can be easily manufactured and achieves the above purpose, and the purpose of manufacturing cost is By. , which includes Mu A to provide a bicycle chain: the package 3 has a body and a reinforcement, wherein: the system is an integrated mountain, the door n- m out of the formed disc 'on the body The outer circumference of the temple spacing ring is provided with a number of chain teeth twist] outer peripheral system / into.卩, a plurality of 5 M356692 sprocket pairs and groups respectively corresponding to the sprocket forming portion 4 (4) are formed on the outer periphery of the body, and at least one side of the ring is convexly provided with a rim of the group. There are a number of arcs... " The circumference of each thickening section; and the support part of the chain (4) should be attached to the inside of the body to enhance the rigidity of the body. Preferably, the circumference of the body formed with the thickened portions on both sides is formed in a wavy shape on both sides of each of the ribs. The parent's reinforcing member is disposed inside the body and between the two to form a shape conforming to the body. Preferably, the reinforcing member is received in the thickened portion of the body. Preferably, the reinforcing member is composed of a plurality of contents. Each of the sprocket sets includes a sprocket, and each sprocket is formed by a pair of sprocket forming portions formed on the opposite chain (four). Preferably, each of the sprocket sets is further provided with an auxiliary tooth which is spaced apart from the sprocket and has a short length of the sprocket. Preferably, the money tooth set is provided with two sprocket teeth, and two adjacent sprocket teeth are spaced apart from each other with a sprocket forming portion not provided with a sprocket set. Preferably, the system is provided with a plurality of perforations, and the body is respectively provided with a J-reinforced portion at the junction of the plurality of perforations, and each reinforcing reinforcement is disposed in the body and between the two reinforcing portions. By the above technical means, the creation can be combined with the body and the reinforcing member to obtain the chain plate through the integral injection molding processing method, thereby not only effectively shortening the time required for manufacturing the chain plate, and; 6 M356692 Providing sufficient rigidity to 'substantially reduce the weight of the chain plate, thereby providing a bicycle chain drive that saves manufacturing costs. [Embodiment] 'This creation mainly provides a bicycle chain plate (ίο), please refer to the P-four figure-the preferred embodiment. As can be seen from the figure, the chain (10) of this creation is matched with - The chain (10) is used mainly for the body ((1). and a reinforcing member (12), the _: • the body (11) is an integrally injection molded disc, on the outer circumference of the body (Π) The equally spaced ring is provided with a plurality of sprocket forming portions (111) corresponding to the chain members (3 ′′), and a plurality of outer peripheral edges of the body (1) are respectively formed corresponding to the key tooth forming portions (111). a mutually spaced pair of sprocket sets (112), wherein each of the sprocket sets (112) includes a sprocket (113) and an auxiliary tooth (114) spaced apart from the sprocket (113) and having a shorter length than the sprocket (113). ), wherein each of the sprocket (113) and the auxiliary tooth (114) are formed by extending a pair of sprocket forming portions (111), and please refer to the second preferred embodiment of the present invention as shown in FIG. In the embodiment, each of the sprocket sets (U2A) is provided with two sprocket teeth (H3), and two adjacent sprocket sets (112A) are separated by an unset a sprocket forming portion (1 i υ of the sprocket set (112A), wherein the body (li) is provided with a plurality of perforations (118), and the other body (11) is respectively provided with a plurality of perforations (118) The body (1) is combined with the reinforcing portion (115); the body (11) is convexly provided with a thickening portion (116) on each of the two side portions, wherein the periphery of the two thickening portions (116) is formed with a plurality of protrusions a support portion (η7) having an arc shape and corresponding to each of the element forming portions (ill), so that the peripheral edge of each thickened portion (116) presents a circular wave shape on both sides of the element forming portion (U1), and Please refer to the sixth embodiment of the third preferred embodiment of the present invention, wherein the body (1 形成 is formed with a thickening portion (丨丨6) only on one side; and the reinforcing member (12) is attached to the body The inside of (1丨) provides the body (1 υ - the required rigidity, wherein the reinforcing member (12) can be accommodated inside the body (11) and between the two thickened portions as shown in the third figure ( 116) is in a shape conforming to the body (11), and the reinforcing member (12) can be accommodated in the thickening portion (116) as shown in FIG. The reinforcing member (12) shown in FIG. 7 is disposed between the two reinforcing portions (116) in the body (11), and the reinforcing member (12) is made of a plurality of metal accommodated inside the body (11).
