New description: [New technical field] This creation is about a kind of bicycle, _ refers to a bicycle structure that can be quickly unfolded and folded. [Prior Art] There are many kinds of folding bikes on the market (10). In order to facilitate carrying or placing a bicycle, it can be folded to reduce the volume when not in use. In terms of folding structure, there are front and rear collars 4 (as shown in Figure ,), but Recorded in the f-fold body touch, 'often accidentally pinching your fingers, and some are contracted back and forth, but for girls with a small amount of I, it is not green, so it can't be quickly deployed. In general, the design of the folding bicycle reduces the length and height of the vehicle. However, in terms of the width of the body, the size of the body is increased, and the looseness and appearance of the mess are both confusing and difficult to carry or tow. In view of this, the creator explored the problems of the prior art in depth, and actively sought solutions to the problems of R&D and manufacturing of related industries for many years, and finally succeeded in developing a folding structure suitable for bicycles. Cover the problem of custom creation. [New Content] The purpose of this creation is to provide a fast-expanding and folding bicycle. In addition to providing a quick and easy deployment and folding, the bicycle is compact and has a beautiful appearance, and is easy to carry and easy to tow. Turn. Referring to Figures 2 and 3, the bicycle 100 can be moved between an unfolded state and a folded state. When in the unfolded state, the first link 20 slides to the main frame 10 The end is fixed. The first connecting rod has a sliding structure for facilitating the sliding and fixing of the first connecting rod 20 on the main frame 1 (not riding), the sliding shot or the roller structure, the rod 201 and the front wheel rod 3〇 Before the steering, the seatpost n extends upward from the main frame bar 1〇, and the height of the seatpost 11 is fixed by the fixing member 111, and the fixing member 111 is provided with a fixing plate hand 112. The rider can be at a personal height. Self-adjusting, the system is in an expanded state as shown in Figure 3. Referring to Figures 4 and 5, when in the folded state, the first link 20 slides toward the second link 21, and the contact bar 1() extends outwardly to form a handle for the rider to move while folding. Seat u to the main frame ω (10), the handle ^ < inside folded and the cup 201 and then the wheel % can be folded inward through the shaft 2 〇 2 (see Figure 4) so the wheel 7 () and the rear The wheel 6Q is overlapped with the shaft, which is convenient for towing on the two wheels' while the current wheel 70 and the rear wheel 60 are coaxially overlapped, and the width is much reduced, as shown in Fig. 5. The second link of the creation of the second link on the shirt bar 丨Q can avoid the finger being connected by the connecting rod or the member, and can reach the _ speeding off and folding. Although this _ has been revealed _ real _ above, but its ribs limit the creation, any person who has the usual knowledge in the technical field, can not make any changes and refinements without departing from the spirit of this creation The scope of protection of 6 M410698 is subject to the definition of the patent application scope attached.
