Description of the new type: [Technical field to which the new type belongs] This creation is about an improved bicycle chain that has a precise controllable length. The tooth tightness is good: strong =-species that can make the chain move forward-move smoothly, Extending the service life two: the overall effect of the bicycle chain is improved in addition to the same effect. A shell effect, to improve the [previous technology] = bar 'is an indispensable component in the technical field of bicycles, so in recent years bicycles The industry's R & D and innovation continue to develop, and the power of _ +% 1 of the 5 is also a breakthrough, and has been shown in the ,,,, and structural aspects of the four-element chain from the most traditional five-seeking, has made the chain Simplification of components :: Don't make it extensively] to reduce the manufacturing process of the chain, and then refine the improvement of the chain plate structure of the chain, and further make the chain of the transmission mechanism, and achieve easy * 5 The effect of controlling movement is smooth. The four-element chain seen so far is in the form shown in the fifth figure. The basin consists of the outer link plate (80) and the two inner link plate (82). ) After pivoting the unit assembly, then enter, The roller ijL * ^ α is connected in series in order to combine the four-element chain of the king, and the role of the 8Ί is to rivet with the chain pin (8 2), so that each part can be pivoted and combined, and the inner link plate (8 1) The larger pin hole ㈣ chain pin (8 2) can be matched to make the inner link plate (8 1) rotate smoothly, while the light chain (8 3) is kept in a freely rotating state, which is conducive to the latching of the chainring. However, if we further understand this kind of four-element chain, we can find that there is still room for improvement, such as: 1. The length cannot be accurately controlled. Because the current chain structure must be based on the two pivot joints as unit units and then connected in series, " Therefore, the total length of the chain must be connected in series with this unit component. In the case of a large unit length, it is impossible to make 5 M275160. • The chain is looped between the front and rear teeth with a proper length, and The situation that the chain is too loose is easy to occur, so it not only affects the transmission effect, but also has the problem of the chain falling off. 2 · The outer chain plate is easy to fall off. · Because the buckle chain is connected by the riveting between the outer chain plate and the chain pin. Connection, so the outer chain plate can only be fixed by the riveting position of the chain pin, and the inner chain plate can be fixed by the outer In terms of the design of the positioning of the outer chain plate clamps on the side, the external chain plate itself has a poor fixing effect, which affects the strength of the chain. 3 · The components are still too many: because the above chain is still the outer chain plate, the inner chain plate, and the chain roller It is composed of four parts such as chain and pin, which not only has many components and causes more raw material costs, but also has a more complicated production_process and assembly process. Therefore, an industry operator has further designed the announcement No. 5956766 chain, please cooperate Referring to the sixth and seventh figures, the two-element chain is formed by cascading a plurality of serially connected units (90), and each serially connected unit (90) contains two link plates (9 1 of the same type) ) And the chain shaft (9 2), in which the two ends of the plate (9)) are connected with the large flange forming part (9 1 2) and the small flange forming part (9 i 3) by inclined joints (9 丄 丄). ), Forming a large flange (9 丄 4) on the large flange forming (9 1 2), and forming a small flange forming portion (g 1). Form a small ⑽ (9 丄 5) can be connected to the small flange forming part (9] 3) of another link plate (9 1) by the key plate (9 丄} 1]), and then the chain shaft (9 2 ) Can be combined to form a tandem unit (90).-The special feature of the above chain is that the structure of the two link plates can be integrated into one type that can be connected to the outer link plate at one end and the other can be connected to the inner link plate. The whole chain has only two components, and each-series unit is only a -pivot point, so each unit length is shortened by many pairs, which can be combined into a suitable length and set between the front and rear chainrings. Key # Composition 'Therefore, in the case that the chain plates are mutually compatible, the strength of the E ^ is increased, and the manufacturing cost is reduced by the design of only two components. ❹ 6 M275160 A more special chain. What is not perfect is that The design of the chain ignores the special effects of all parts of the chain. The role of the chain roller is that the chain meshes with the toothed disc. When the teeth of the disc are inserted into the locking space of the chain, the teeth can be connected to the chain. The freely rotating chain is not only able to make contact, not only can make the movement of the latch more smoothly, but also can avoid the zero caused by excessive friction. The problem of easy damage, so in the field of design of the chain, the chain is important. However, the above-mentioned chain takes into account the cost problem, and the parts are separated, but the smoothness of the chain's operation is seriously affected. Directly contact the outer perimeter of the large flange of the T key plate, so it is easy to cause wear on the surface of the large flange and affect the service life of the chain. Furthermore, it can be seen from the seventh figure that the small flange of the chain plate (9 1 5) is located inside the large flange (9 i 4) of the other link plate, so in addition to contact between the two chain plates with adjacent planes, the periphery of the small flange (9 1 5) = also with the large convex The inner periphery of the edge (9 1 4) may appear in a contact state. Because it is not only easy to cause interference, but also frictional resistance will affect the rotation of the chain, which is still not a practical design. [New Content] Therefore, in order to provide-a more practical chain, the creator designed the original bicycle chain ", the chain is composed of chain plates, chain rollers, and chain pins on both sides, and then the key chain is connected by unit components , Where the chain plate-end ^, and the inner end with an inner flange, the outer end is connected inward The two are connected by a beveled surface, two ^ ^ q side chain plates are attached with corresponding inner flanges and the assembly chain is better than 'the other end of the other chain plate is divided into soil, ..., offending the outer side of the inner connection end, The compound M is made of chain pins and riveted, that is, it is composed of a chain made of 斡 i. This chain has a length that can be made by Cui Cai, good tightness between teeth and teeth, and ancient ρΒ. In addition to its strength, it is also special. Further, by freely rotating the key 矣 b 'between the link plates, the movement of the chain and the chainring is smoother. M275160, and the flat end design of the outer end of the link plate is connected to the inner end of another link plate. The connection minimizes the mutual interference between the chain plates, thereby increasing the service life of the chain. Therefore, the overall structure presented in this creation has the following overall effects: 1 · Through the design of the chain rollers in this creation chain It can maintain excellent contact between the teeth and the teeth, and can avoid improper grinding of the components, thereby extending its service life. 2 By overlapping the flat plate-like outer end with the inner end with the inner flange between the plates of this creation, the interference problem can be minimized to maintain the smooth operation of the chain. Design / -fr «Control the length of the chain. The design of the chain is based on the design that the chain is connected from the outer end of one chain plate to the other chain plate, which can increase the strength of the chain. I 5 With the three-element design of this creative chain, it is still more effective than the four-element chain: it has a significant effect of reducing the cost of preparation, and it can still be used under the situation that the cost of the action St is slightly higher than that shown in the sixth and seventh figures. With the freely rotating chain rollers to achieve the necessary functions of force and smoothness, on the whole, it still has excellent practicability. [Implementation],. This creation "Improved bicycle chain is formed into a 璟 -shaped opening >" 7L components as early as possible; • Shows how bad it is, and then worse, the endless chain is composed of joint members. ^ The early element assembly is of the type shown in the first figure, and the first pass is the head I 丨 e, and the chain is composed of the link plates (] _ 〇) and the chain pins (3.0) on both sides. The first Hai chain plate (1 0) is a one-piece design, with a small end (connected with a horse-shaped plate), an external end (1 1) and a pin hole (1 1 Ί) ^ 口 χ χ ^ And the other 8 M275160 'but inscribed' and (1 2) 'inner end (1 2) is formed with an inner flange (1 2 1) inside, and a pin hole (122) is formed in the inner flange (121), However, the diameter of the face (χ 2 2) of the inner end (1 2) is slightly larger than the diameter of the pin hole (work 1 1) of the outer end (丄 丄), which is different from the outer end (1 1) and the inner end (1 2) Connected by a beveled surface (1 3), and the other chain report (2 0) is a hollow cylindrical shape, the internal hole diameter is larger than the diameter at the upper and lower ends, and the inner diameter of the upper and lower ends is slightly Larger than the outer diameter of the inner flange (1 2 1). 4. Please cooperate with the third figure to show that the n edge (1 2 1) of the two-key board (1 0) can be stuck to both sides of the money (2 ◦), so that the two-chain mountain is convex and the edge ( 1 2 1) Correspondingly, at this time, the distance between the two link plates (work 0), Bu: (11) is greater than the distance between the inner link ends (1 2) of the two link plates (1 0). —Silk & Silly "Bamboo force chain plate (1 0) The outer end (work) is not corresponding to the" hole "(12) of the inner end (12), and the key pin (3〇) Forcibly enter the pin hole ⑴ 仏 (122). After the two ends of the chain pin (30) are divided into _ = (1 Q), the two ends can be riveted and fixed, and the unit component is formed, and according to the above two =: The chain is connected in series, and the lower end of the chain pin (30) ... can be divided into ::% section (3 1). After the assembly, the concave ring section (3 1) is located at the pin 1), thereby making the action of the chain more Flexible. = As can be seen from the third ® towel, the chain of this creation is in the shape of a flat plate 2) and the other—the inner end of the key plate with the inner flange (…) end ⑴) so it is on the chain pin (3〇) After assembling 'external terminal :: the internal terminal (12) of the board contacts, in the case of small contact area In the case of non-interference, the frictional resistance can also be reduced to make the chain move more smoothly. In addition, according to the third and fourth figures, it can be seen that the chain plates (本 〇) 9 of this creation are placed between M275160 and Freely rotating chain pro (20), so when the teeth of the chainring (40) are engaged in the latching space between the chain plates, they are in contact with the chain roller (20), and the chain roller (20) In the case of free rotation, not only can the cooperation between the chain and the tooth plate be smoother, but also the chance of the chain plate being worn by the teeth can be reduced, thereby increasing the service life of the chain.
