[Claims for Utility Model Registration] 1. Relates to a new structure for a folding bicycle, including the following: One handlebar structure, which includes one fitting tube 5, one fork, and one foldable handlebar 7. A fork is connected to the lower end of the fitting tube, and a front wheel is installed on the fork through a fixing hole provided at the end.An upper fitting tube 6b and a lower fitting tube 6a are provided at both ends of the fitting tube, respectively. The foldable handlebar 7 is connected to the upper end of the fitting tube.The two handlebar pipes of the handlebar are respectively inserted into the two left and right C-shaped pipes 8, and The ferrule fixed by a ferrule 9 is divided into an outer ferrule 9a and an inner ferrule 9b, and a concave tank 10 is formed between the outer ferrule and the inner ferrule. When the C-shaped pipe 8 is connected, the front end of the C-shaped pipe and the concave tank 10 are just connected to each other. When the handlebar is folded, first pull up the ring to separate it from the concave tank 10, and then the handlebar is folded. The handlebar is folded down along the notch of the C-shaped pipe, and the handlebar is folded around the fulcrum 11 that connects the handlebar and the C-shaped pipe as the center of rotation; The lower side of the ferrule 5 in the bar structure is connected to the ferrule 6a by a pin, and one safety hook is provided at the bottom of the rear end of the front frame; It is connected to the front frame above the point of intersection between the two from the rotation axis, and a safety cutter pin is provided below the front end.This safety cutter pin and the safety hook of the front frame are hooked together, and the front frame and the rear frame are The rear wheels are connected to each other at the rear end of the rear frame;
It includes one seat support shaft 21, a seat support shaft 16, and a front support wheel 15, among which the seat is supported at one end of the seat support shaft, and the other end is connected to an active fulcrum of the rear frame; One end of the shaft supports the seat by supporting the seat support shaft, and the other end is jointed to one active fulcrum of the front frame; one end of the front support handlebar is jointed to one active fulcrum of the seat support shaft. The other end is connected to the upper ring 6b of the ring 5 in the handlebar structure by means of a pin; one brake fork, the upper part of which forms a flat brake fork plane; When the flat brake fork becomes vertical, the safety cutter pin on the rear frame is pushed up, the safety cutter pin is used to lock the front frame, and the front frame is separated, allowing the folding operation to be performed; The folding petal structure is composed of two left and right foldable petals 24a, 24b, one chain foil shaft 22a, and one petal foil shaft 22. Among them, the petal foil shaft 22
is located on the shaft above the rear frame, and its characteristic is that the chain wheel axis passes through the petal wheel axis and fixes the two left and right foldable petals on the same axis. Something to do. 2 Claims for Utility Model Registration A new structure for the folding bicycle mentioned in paragraph 1, in which the safety cutter pin provided on the rear frame is placed in one cutter shell, and the cutter shell is further inserted into the rear frame. The inside of the cutter shell, which is locked upward, uses one spring to push up the cutter pin, and the front end of the safety cutter pin has two convex blocks.
A concave tank is formed between the two convex blocks, and the front side of this concave tank forms a slope to the rear. The shape of the front end of the convex block is exactly compatible with the locking mechanism of the safety cutter pin, that is, the front end of the safety lock is also provided with one inclined convex block, and the safety lock is connected to one at the front end. Its characteristic feature is that it forms an inverted hook-like structure. 3. In the new structure of the folding bicycle mentioned in paragraph 1 of the claims for utility model registration, the two foldable petals on the left and right of the foldable bicycle structure have one long nail bar and one long nail bar, respectively. It includes a rotating plate, one petal, and one petal lock arm, the rotating plate is placed inside the petal, and one long nail bar crosses the rotating plate and connects them into one. The rotating plate is further connected to the petal lock arm by one bearing and a support shaft, and the petal has one notch above the one side near the petal lock arm, and the petal is connected to the petal lock arm by a long nail bar as an axis. Its distinctive feature is that it is folded upward at a 90 degree angle. 4. The novel structure of the folding bicycle described in Claim 1 of the Utility Model Registration Claim, in which the petal foil shaft 22 therein adopts a connection structure that can be expanded and contracted by one in connection with the rear frame. , supported by a support frame 62, and connected to one "U" type iron 61 by fitting on one side of the support frame 62, and one "U" type iron 6
1 is again fixed in the inner space surrounded by the four support shafts on the rear frame 14b, and the other end of the petal foil shaft is also connected with an iron piece 63, which has a similar structure at an appropriate position on the seat support shaft 21. The iron pieces 64 are folded up and down, connected and fixed, and the bottom of the seat support shaft 21 is also made of one “U” type iron 60.
Based on the above-mentioned overall structure, the "U" shaped iron 60 is again fixed in the internal space surrounded by the four supporting shafts located on the other side of the rear frame.When the vehicle body is unfolded, the petal foil shaft 22
It is gently hung on the upper support shaft of the rear frame 14b, and when the vehicle body is stowed, the petal foil shaft 22 rises to reach the minimum storage volume. 5 Utility Model Registration Scope of Claims A new structure for the folding bicycle mentioned in paragraph 1, in which the petal wheel shaft 22 is directly fixed to the support shaft on the rear frame. 6. The petal structure mentioned in paragraph 3 of the claim for utility model registration, in which the rotating plate is made in a “convex” shape, the long nail bar crosses the rotating plate, the center of gravity is offset upward, and the petal Its characteristic feature is that the front side of the head is permanently oriented upwards.
