New description: [New technical field] This creation is about an improved shifting chain, especially a shifting chain that is easier to access. [Prior Art] In the technical field of self-driving cars, the combination of a chain and a sprocket is the most indispensable transmission member, and the transmission of the chain can transmit the power of riding to the rear wheel to drive the bicycle forward. θ, the speed of the traditional bicycle is only obtained by the sprocket set of the single speed ratio. In order to make the bicycle have the function of shifting, in order to ride in different road conditions, the speed bicycle has become the mainstream of bicycle in recent years. Moreover, by reducing the width of the sprocket, changing the width of the chain, the improvement of the chain plate, and the like, the function of the shifting function is further enhanced. ▲ Among them, the improvement of the chain plate is mostly focused on the cooperation with the sprocket, so that the key bar can make the sprocket easy to enter during the shifting process, so that the interference of the human gear can be avoided, and the noise is minimized. For example, Announcement No. 390337 "Improvement of the outer chain plate of bicycle chain" is the structure designed by the creator. It is: the outer side of the outer side of the outer chain plate is connected by the waist, and the high part is formed at the center of the waist. The high rise is extended from the lower end of the _ side arc surface to the upper end of the arc at the upper end of the cut end and forms a protruding portion which protrudes outward, thereby making the chain easy when the chain is in the upper gear The self-cutting portion is snapped into the sprocket to provide an easy-to-up shifting chain. However, although the above structure has the effect of the county's Shangyu Dan 1 with #笊上棕, it is only for the improvement of the M360845 outer chain plate, but in the design of the chain, in addition to providing the entry space by the two outer chain plates. In addition, the inward space is also formed between the two inner chain plates. Therefore, if the in-situ zone is located in the inbound space of the inner chain plate, even if the design of the outer chain plate is easy to be superimposed, the design cannot be used, and it is still difficult to enter. Trouble with the file. • As can be seen from the above, the design of the shift chain is still in need of improvement' in order to provide a chain that can be more easily loaded. [New content] Φ edge is the main purpose of this design, providing a "modified shift chain" 'the chain consists of two outer chain plates, two inner chain plates 'chain rollers and chain pins to form a chain unit' The chain pin is pinned to form a loop-shaped chain, and a concave cut-in portion is formed between the outer ring plate and the circular arc surface on both sides of the inner link plate, and the cut-in portion extends from one side of one of the circular arc faces to the other The other side of a circular arc surface, which is viewed from a plan view, has a slanted cut-in portion, whereby the design of the two outer chain plates and the entry space formed by the two inner chain plates are inclined. The cut-in portion 'and the outer side of the inner chain plate is still flat and has no protruding state, so that it is not only easy to be up-shifted, but also can reduce the obstacle of shifting. [Embodiment] The "improved shifting chain" of this creation mainly consists of two outer chain plates, two inner chain plates, a number of chain rollers and a number of chain pins, and the chain pins are used to form a chain ring. Chain, and the structure of the creation is as shown in the first figure and the first figure. [Each chain unit (丨〇) contains two links (11) and two corresponding inner chain plates (11). And the chain roller (13) and the chain pin (14) group-to-chain unit 'where the outer chain plate (11) forms an arc surface M360845 (111) (112) on both sides, and the arc surface (111) (112) Each of the pin holes (113) (114) is formed to form a waist portion (115) connecting the arcuate surface j 12) at the center, and a recessed cutting portion 〇 16) is formed at the waist portion (115), and the cut portion (11 6) From one of the arcuate faces (one side of the weir to the other side of the arcuate face - (11 2 ), it is in a state of being inclined from a plan view, and outside the outer link plate (11) The flat shape shown in the figure can also be in the protruding shape as shown in the fifth figure; the inner chain plate (12) is designed to form a circular arc surface on both sides (121) (122 ), arc surface (121 (122) each forming a pin hole (123) (124)' and forming a waist portion (125)' connecting the arc surface (121-8122) at the center and forming a recessed portion at the waist portion (125) (丨26) The cut-in portion (126) also extends from one side of one of the circular arc faces (121) to the other side of the other circular arc surface (122), so that it is obliquely viewed from a plan view, and is also in the inner chain. The outer side of the plate (12) is in the form of a flat plate; the outer link plate (11) and the inner link plate (12) are combined with the cut-in portions (116) (126) facing inward, and when assembled, two The inner chain plate 〇 2) is placed between the chain > roller (13) 'and the outer chain plate (11) is placed outside the inner chain plate (丨2), and then forced into the outer chain plate by the chain pin (14) (11 ), the inner chain plate (12) and the chain roller (13) are formed into a chain unit (10)' and then connected by a chain pin to form a loop-shaped chain. The combined chain is viewed from the side of the third figure, and an inward space (2 〇) (30) is formed between the two outer chain plates (丨i) and the two inner chain plates (1 2 ). It can be seen that this entry space (20) (30) is designed by the cut-in portion (116) (1 26), - the entrance space (20) (30) is increased, and is shown in the fourth figure. It can be seen that when the chain M360845 and the outer chain plate do not form a space which is easy to make the sprocket, it is stuck between the inner and outer chain plates, and the obstacle of shifting is reduced, and the chain with better wheat speed effect is better. When the bar is to be introduced into the key (4 Ο ) of the sprocket, the end edge of the sprocket contacts the cut-in part, that is, enters the entry space (2〇) (3〇) along the cut-in part, forming an easy-to-access design. Furthermore, the outer side of the inner chain plate (12) of the present invention has a flat shape, so that the sprocket can be avoided, and a simple description can be provided.
