Description of the invention: [Technical field of the invention] The present invention is an improvement of a folding structure of a bicycle, in particular, a folding device is arranged on the front and rear frames. The bicycle folding structure is improved. 4 200808608 [Prior Art] For the GM, the self-defense car is undoubtedly the county's light transportation and meets the requirements of environmental protection, so it is widely used by the public; the bicycle industry is currently developing various bicycles. The bicycle that can be folded and folded has the advantages of not occupying the storage space and carrying the convenience of carrying, and is favored by consumers; at present, the folding bicycle has a complicated folding structure design, mainly for reducing the folding of the bicycle. The designer who takes up space; the more common design, as shown in Figure 1 of the Qingmai reading, is the national patent No. 263293, which is to cut the main frame of the bicycle 10 between the front and rear wheels. The first and second fastening pieces 121 122 of the first and second fastening pieces 121 are respectively installed at the two end portions of the cut main frame tube π, and one end of the first and second fastening pieces 12丨122 The side is connected by a pivot 123 and is detachably slid on the first fastening piece 121 by a quick release member 124; thereby, the first and a fastening piece 121 122 of the fastener π can be transmitted through the side. Pivoting with the pivot 123 as the axis When the first fastening piece 121 122 is abutted, the first and second fastening pieces 121 122 can be tightened by the quick release piece 124 to perform the combined work of the bicycle 1 ;; and when the quick release piece 124 is loosened and When the first and second fastening pieces 121 122 are pivotally separated, the folding operation of the bicycle can be performed; it is noted that the above-mentioned transmission is provided with a buckle on the main frame tube, although the folding of the bicycle frame can be performed. Or relying on the joint operation, but in the actual use and operation of the 200808608, there are still problems and defects of the feeding; for example, the function of the fastener is quite single, when the _, a pivotal separation, the bicycle Fold (four) business hours, ^ through the purchase of ^ π, tied f, tied to the f-folded frame, in order to allow the folded car to arbitrarily pivot 'extra band, strap is not only inconvenient to use, and ^ The normal appearance problem of the bicycle; If the bicycle parking frame tube is carrying the gamma amount, the force value of the second:: bearing is quite high, and the quick release member is used as the fastening and clamping structure. The quick release must be kept constant: the brother and the second buckle will loosen. When the bicycle is in a bumpy road condition, the first -_ = piece will have a slight sway from the pivot first, and after a long time, it will affect the degree of force of the piece: Life is immediately dangerous, but the user will be disturbed by the psychologically static It: to ensure the quick-release state of the quick-release parts, the extremely difficult/square of the wire caused by the (4) can be designed - the folding structure replaces the aforementioned fastening The folding frame can be used to fix the frame through the _ structure, and on the other hand, the user can be satisfied without worrying about the actual needs of the (four). Psychological problem of the reduction [invention] 6 200808608 yuw, in the provision of a bicycle folding structure to change the people, the invention is particularly fixed through the insertion of the tip as a folding device, the insertion is directly through the two loose pages The perforation of the piece does not occur when the phase is shaken; in addition, the tip can be folded as the front and rear frames of the bicycle in addition to the fixed tip when the folding device is combined. It is necessary to pass through the two-position frame to limit the front and rear frames _, which solves the problem that the conventional structure must pass through the bundle (four) to fix the front and rear frames. [Embodiment] In order to achieve the above object, the present invention aims to achieve the above-mentioned objects, and the techniques, means and effects thereof are safe and feasible _ and with the detailed description of the figure as follows; first, 'Ming with tea readings 2, 3, 4, 5 The bicycle folding structure improvement provided by the embodiment of the present invention is mainly composed of a folding device at the two ends of the bicycle frame and a plug; wherein: the main frame 20' is used as a front and rear wheel of the bicycle. 21 is a main frame that is coupled to the front axle 21 of the front wheel 21 and a rear frame 24 to which the rear wheel 22 is coupled, and the front and rear frames 23 24 each have a The connecting ends 231 241 are contiguous with each other; the yoke 30' is correspondingly disposed by the two flaps 31 32, and is constituted by a pivotal connection of the one end side of the second flap 31 32 with the pivot 33, the two sheets A perforation 3n 321 is defined in each of the pieces 31 32; a leaflet 31 is fixedly coupled to the connecting end 231 of the frame 23, and another 200808608 f page 32 is connected to the connecting end 241 of the rear frame 24. The phase is fixedly connected, so that the rear frame 23 24 can be passed through the folding device. The pivoting link; the 4th insert 40 is inserted in the folder 3, and the second flap 31 is affixed to the two corresponding perforations 311 321; thereby, the front and rear of the bicycle: 23 24 Complete the combined work, or self-folding _ take out the plug 4 〇, so that the 'rear car * 23 24 peak 33 for the axis of the bicycle frame frame turning cooperation. In the above, the positional force of the components and structures of the present invention is designed through the folder structure of the present invention, and the user can perform the combination or folding operation of the front and rear vehicles, and is not only easy to operate, but also The user turns around and is worried about the problem of stable insertion.
