New description: [New technical field] [This creation department has a kind of anti-drop chain, especially it can be set on a folding bicycle, so that when the bicycle is folded, the drive key can be avoided. A folding bicycle key switch that produces a drop-type bicycle that is clear and easy to assemble and reduces manufacturing costs. [Prior Art] According to the trend of tourism and leisure, the number of families who buy bicycles to carry out activities is increasing, and the global energy crisis is getting more and more attention to the business opportunities of environmental protection concepts. We have launched a variety of bicycle products, and with the increasing awareness of consumers' energy-saving and carbon-reducing environmental protection, coupled with the weekly break, the bicycle is no longer just a visitor and a travel tool. The bicycle has the advantages of no fuel consumption, no noise, no pollution and time-saving. It is used by many people as a fitness and sports tool. Some people even use bicycles as a break and travel companion around the island. The bicycle structure will occupy a certain space when it is parked and stored. Therefore, the industry has introduced a bicycle with the main purpose of _ stacking, and the general user will carry the bicycle body to the material riding 'and convenient to enter (4) (four), elevator Etc., and easy to place in the storage room. The folding bicycle is divided into a horizontal folding bicycle and a vertical folding bicycle. Please refer to the folding bicycle shown in the fourth and sixth figures. The anti-drop chain of the folding bicycle (4) is one of the longitudinal folding bicycles. The pivot u for turning is usually set on the 1st spindle 12 (also known as the five-way pipe) and the rear wheel of the bicycle. 13 wheel _, so that the rear wheel 13 and the rear frame 14 can be rotated downward according to the pivot 丨丨 as a fulcrum and folded toward the front frame π (please cooperate with _7, eighth_show) to narrow The bicycle is bulky and easy to carry and collect. The folding bicycle 1() and the general bicycle are provided with a pedal 16 and a driven wheel 17'. The pedal 16 and the driven wheel 17 are provided with a _ bar 8 so that the thin wheel is pedaled by the user. After the shaft rotates, the driven wheel 17 is driven by the chain 18, and the rear wheel η is driven to drive the bicycle. However, if the bicycle 1() is not equipped with the folding bicycle of the present type, it is prevented from falling off. The chain device has at least the following defects: 1. After the Tianjia frame 15 and the rear frame 14 are relatively turned, the rotation between the pedal 16 and the driven wheel 17 for mounting the strip is small. The chain 18 is loosened from the original tight end state, and the problem of _ noodles _ falling (falling off the chain). 2. When the folding bicycle 1G is unfolded after being folded, the user must reattach the key bar 18 to the pedal wheel 16 and the driven rim so that the folding bicycle can be ridden. Therefore, if the folding bicycle is not equipped with an anti-drop chain, it is quite inconvenient for the user to use. For the technology of custom-made car anti-drop chain, please refer to the Taiwan Patent Notice No. 四(4). The bicycle folding type will turn the front frame down, and the rear wheel and rear frame tree car of this creative bicycle will be purely financial. Correction, in addition, the Taiwan Patent Publication No. 547413 uses a support wheel with elastic elements to support the chain. The structure of the chain is supported by the creation of 6254 = two cut bodies. The structure is also complicated and complicated. = Patent Announcement Cost. It is not easy to assemble and increase manufacturing. (4) Seeing the early transition chain is 'The creator is constantly researching and improving innovation based on products.

[New content] The purpose of this creation is to provide a folding type bicycle anti-dropper that can be placed on a folding bicycle and can be dropped (chain-off) when the bicycle is folded. Another object of the present invention is to provide an anti-dropper for a folding bicycle that is easy to assemble and which can reduce manufacturing costs. In order to achieve the above purpose, the creation structure comprises a bracket and a plurality of supports, wherein the bracket is provided with a mounting, and the mounting is formed on the main shaft of the weaving bicycle; and the dragon is disposed on the bracket; When the folding bicycle is folded, the driving chain of the folding bicycle is thrown by the branch body, so that the (four) chain is kept in a tight end state without falling (dropping). The following is only a detailed description of the specific embodiments and the drawings, so that your review committee can have a better understanding and understanding of the functions and features of this creation. [Embodiment] 5 M396254 Please refer to the first and sixth figures. The anti-dropper 20 of the present folding bicycle is installed on the folding bicycle 1 (this embodiment is in the existing longitudinal direction). The folding bicycle is used as a solid complement. The preferred structural relationship includes a bracket 21 and a plurality of supports 22 of the bracket 21. The bracket 21 is mounted on the folding bicycle 10' and is supported by the bracket. 22 supports the chain 18 of the folding bicycle so that the chain 18 is tilted to the end without falling (dropping). Please refer to the first, second, and third figures. The bracket 21 of the present invention has a predetermined angle 51 between the two side frames to form an inverted v shape, and the bracket 21 is folded with a number of angles 211 The bracket 21 is provided with a mounting hole 212, and the elongated slot 213 for mounting the supporting body 22 is disposed at the proximal end of the body. The support 22 (side) is provided with a fixing hole 22 through a fixing member 222 such as a screw member, and is screwed into the fixing hole 221, and when the fixing member is tightened, the support (4) can be (4) The money 21 branch meeting _, if the shed is fixed, the branch body 22 can be moved along the chute 213, whereby the set position of the support body 22 can be adjusted to make the support body 22 When the bicycle iq is folded, the chain 18 can be appropriately swayed to maintain the tightness of the chain 18; the trap 22 is column-shaped, and the surface ring is provided with a groove 223, so that an elastic body is disposed as rubber. The groove 223 has a predetermined elastic supporting force when the surface of the supporting member 22 is supported on the chain 18 and can improve the frictional viscous force between the branch 22 and the chain 18; the surface of the supporting body 22 is provided with - The flange 225, in this embodiment, the flange is extended by the groove 223, wherein the side wall is extended to prevent the chain 18 from slipping off the surface of the support body 22, thereby preventing the chain 18 from slipping off the surface of the support body 22. . See the fourth, fifth, and sixth figures for the installation of the anti-drop chain If 2G for the creation of the folding bicycle. The folding bicycle 1 () is provided with a spindle 12 (also known as a five-way tube). a set of shafts 19 (also known as five-way bearings), the set of shafts 19 are provided with a thread 191 to be assembled with the master cylinder 2, the set of shafts 19 is provided with a shaft 192 slightly The end portion of the set of axles 19 has a flange 193 in the proximal jaw portion 191, and the anti-dropper 2Q of the original folding type bicycle is stored in the =, , and ' texts. P191, when the set of axles 19 are screwed and fixed to the main shaft 12, the dog rim 193 is fixed to the main shaft 12 by the bracket 21, and the folding bicycle anti-chainer 2G is closely disposed therein. , the pedal π is sleeved on the hinge 192 ′ and the pedal 162 is threaded by a screw 163 and the screw (10) is locked to the shaft 192, so that the whole creation The folding bicycle anti-dropper 2 is easy to install on the folding bicycle. The month's seventh, eighth, and ninth diagrams show the folding movement of the folding bicycle and the indication that the creation can prevent the money from falling (dropping). The first is the miscellaneous wheel 13, The rear frame 14 can be rotated downward with the pivot 11 as a fulcrum to receive the σ ' toward the front frame 15 and then the yoke 151 is turned to be folded toward the front frame 15, and the handle 152 is bent toward the front. The frame 15 is folded and the seat cushion 153 is retracted into the front frame π, so that the slot can be reduced in size by the brakes, so that the user can carry and place in the storage room.
