New description: [New technical field] This creative department is a technical field of bicycle components, especially a type of clearing that can be broken off and can be hooked even when the key is dropped. A chain fall arrester that prevents the key bar from falling and is stuck between the sprocket and the frame. L has no prior technology. When a bicycle is in a chain-breaking situation, the chain can easily be locked between the key wheel and the frame of the bicycle as the key wheel continues to rotate. And - but the chain is stuck in the sprocket and the frame of the bicycle, so that the bicycle of the machine can be bribed, so it is easy to send. When the chain of the city chain is stuck, the damage to the chain and the car (4) is also very good. When the card chain is removed, it is very time-consuming, laborious and troublesome to remove the crank and the sprocket. Seeing the bicycle to prevent the chain from being used, ^ often will be on the rut (4), the loss of the death of the Loka, the danger of the chain, the device that prevents the chain from falling, as shown in the patents of Taiwan Announcement No. 5U621, No. 255846, the box 3 ° The anti-drop chain device of the 5 种 白 知 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要 主要On the outside of the lower side of the key strip, the _ strip cannot be detached from the far sprocket.妙x' is only used by (4) to prevent the drop of the key strip from being used on the shifting machine, that is, it is only used for the bicycle, the pair, and the side of the car, because it will block the chain on the sprocket. I can't change the speed without leaving it. Moreover, the device for preventing the chain from falling is more problematic in that it is bulky, heavy in weight, complicated in structure, and high in cost. In particular, it is a sprocket wheel and a crank member when assembled, so it is also very troublesome and inconvenient to assemble. In view of this, the mine personnel developed and designed this creation in response to the above-mentioned conventional bicycle anti-drop device in the structure and the lack of improvement caused by the lack of improvement. . [New content] The main purpose of this creation is to provide a kind of reduction _ situation, and even when the chain is dropped, the key bar can be hooked to prevent the chain from falling and being stuck in the sprocket and the frame. The chain between the fall arresters. Specifically, the chain protector of the present invention includes a bundle member and a stopper. The bundle can be quickly placed on the solution of the Wei bicycle. The = rod includes a - rod body and a - hook chain body. The upper end of the rod body-fixing section, the extension section and the -blocking section has a coupling hole for detachably coupling on the a-beam member. The extension section is inclined outwardly from the lower end of the fixing section. The resisting section extends downward from the lower end of the extension to the side of the chain. The hook chain system is combined with the outer side of the lower end of the messenger section to hook the dropped key strip. The top surface of the hook chain is inclined to the downward direction of the blocking section, and the angle between the inclined surface of the hooking body and the outer side of the resisting section is a degree. In this way, by blocking the blocking section of the bar on the inner side of the chain, the chain speed bicycle of the bicycle can be prevented from falling on the key wheel, so that it can be applied to the variable resistance 栲俨瞎Striving for the future, even if the force of the key bar is too large, the two can be stretched out. The hook chain hooks the _ strip to prevent the chain from falling between the rims and the frame to avoid Dangerous. Moreover, the volume is small, lightweight, and the structure is relatively simple, so the manufacturing cost is also relatively small. Therefore, it is known that the volume, weight, structure I, and cost (W) are different from those of Wei. In addition, the profit beam assembly can be quickly and easily incorporated into the wire of the bicycle, and the problem of assembly trouble and money caused by disassembling the components such as the sprocket and the crank during assembly of the conventional anti-sliding device can be improved. In the present creation, the angle between the inclined surface of the hook chain and the outer side of the blocking insert is preferably 60 to 90 degrees. K Jiadi's creation of the sowing bar can be used to fix the thread through the joint hole of the fixed section of the rod on the beam, the combination can be used to adjust the cross (four) bar up and down according to actual needs. 'Left and right move. In the present creation, the hook chain body and the rod system may be integrated, or the hook chain body may be combined with the rod body by means of a combination of the silk thread and the village. σ~干 [Embodiment] Please refer to the figure -~6, which shows that the chain anti-dropper described in this creation includes - bundle 1, derailleur 2, - strut 3 and - fixed thread inspection 4 . among them. The side bundle member 1 includes a fixing sleeve 1〇, a movable sleeve and a screwing member a. The fixing sleeve 10 has a connecting portion and a locking portion 101 at both ends thereof, and a half ring groove 102' has a through hole 1〇3 between the two. The connecting end portion of the movable sleeve 11 is swingably coupled to the connecting portion (10) j' of the fixing sleeve 1 (), and the other has a locking portion 11Q, and a central portion has a semi-ring groove. The half ring groove 102 of the ferrule 10 and the half ring groove (1) of the movable ut can be attached to the seat tube 5 of the shifting bicycle 5. The screwing member 12 can be screwed onto the locking portion 1〇1 of the fixing sleeve 10 and the locking portion ι of the movable sleeve u, so that the sleeve 1G and the movable sleeve u fast tighten the seat. Tube 5〇. The splicer 2 is coupled to the fixing portion-connecting portion (10) of the bundle member i, and has at least one fixed screw hole 2q for the slanting portion. The dial button is used to move the hybrid bicycle 5 _ bar 51 for shifting operation. The support rod 3 includes a rod body 30 and a hook chain body 31. The shank 30 is in the form of a 32 extension section 33 and a _ section 34. The upper end of the shaft, such as 2, has a ten-shaped coupling hole 35. The extension & is made by a fine segment: the lower end is inclined downwardly at an angle to the direction of the smallest front chain of the variable speed bicycle 5. The blocking section 34 is formed by the extension 33 ... =::=2, and the chain 51 has a gap between the chain 51, the gap is smaller than the ', and the upper end of the resistance button 34 is slightly higher than the The most sprocket's visibility, the lower side of the outer side of the blocking section 34 has an inner slant: "the periphery. The system extends from the lower end of the damming section 34 to the outside, the hook chain 31. 31 The resisting section 34 is inclined downwardly - the slope 3: the surface of the (four) plane is inclined toward the outer surface of the resisting section 34 and the angle of the outer side of the resisting section 34 may be between 60 and 90 degrees. Preferably, a 3 (the fixing bolt 4 passes through the coupling hole 35 and the through hole (10) and is screwed in the Guding screw hole 20. In this creation, the inspection 4 can also be fitted to the J. - A variety of types of material 4G ribs increase the stability of the yoke bar 3. Since the present reading lever 3 _ 34 is the shifting of the inner side of the chain 51 on the smallest front sprocket 52 of the wealth 5 It is possible to prevent the ship 51 that has been shifted from (4) 5 from being dropped by the minimum front sprocket 52. In particular, when the force of the falling of the miscellaneous 51 is too large to open the blocking section & Chain 31 The chain 51 (10) stops the strip 51 and is stuck between the minimum front sprocket 52 and the frame to avoid danger. Moreover, the support rod 3 is small in size, light in weight and simple in structure. It is also more convenient than Z. 'Spicy people can combine it on the seat tube 50 of the Qingqi bicycle 5, making it easier to assemble, convenient and fast. 凊 See the seventh figure, it is pointed out that The cross-shaped coupling hole 35 of the blocking rod 3 is further provided for the movement of the fixing screw 4 in the upper, lower, left and right sides thereof for facilitating adjustment of the gap between the segment 34 and the chain 51.凊 Refer to the first embodiment of the eighth hybrid forest creation. It is pointed out that the hook chain 31 can be screwed to the lower end of the blocking section 34 by the screwing member 38. Please refer to the ninth® for the creation of the hybrid 3 _ two implementations, which indicate that the hook body is locked on the blocking segment 34. The second can be a screw, and its direct screw Referring to the drawing shown in the tenth figure, it is pointed out that the third embodiment of the mast 3 of the hook chain 1 is the blocking section 34. The lower end can be directly set by the socket method.
