The first body has a first pivot seat of the at least one first hole; the second body has a second pivot seat of the at least one second hole. The at least one pivot pivotally connects the first yoke seat and the second pivot seat by penetrating the at least one bushing, the first hole and the second hole. According to an embodiment of the present invention, the folding device has two frame shafts, two first holes, two bushings, and two second holes. The corresponding x-axis, first hole, bushing and second hole are respectively fixed together. Another object, advantage, and novelty of the present invention will be described in the following detailed description in conjunction with the accompanying drawings. In order to make the above description and other objects, features and advantages of the present invention more obvious and obvious, the specific embodiments of the present invention are described below, and the drawings are described in detail below. [Embodiment] Referring now to Figure 1, a folding apparatus 1 for a folding bicycle 9 having a bushing for joining two separate components (e.g., a frame, a handlebar) of a folding bicycle according to the present invention is provided. The folding device 1 can be applied to the proper position of the handle frame 2 or the bicycle frame 3. Please refer to FIG. 2 and FIG. 5 together with respect to the folding device 1 applied to the frame 3 according to the present invention. Please refer to FIG. 2 to FIG. 5 together with regard to the basic structure of the folding device 1. The folding device 1 includes a first body 10, a second body 20, and a locking device 30. The second base 20 is pivotally connected to the first base 10; the locking device 30 is pivotally connected to the first base 10 and the second base 20 for the first base 10 and the 5 M412916 second base 20 Can be selectively locked or separated. The locking device 30 of the embodiment includes an operating handle 31 and a rod 32. The two ends of the rod 32 are respectively pivotally connected to the second seat body 20 and the operating handle 31. The operating handle 31 has a handle pivot 311, which is The frame is connected to the two holes 15 in the first seat body 10. Therefore, the first body 10, the second seat body 20, the operating handle 31 and the rod 32 form a four-bar linkage as in the conventional case. Since the folding device 1 using the four-link set (the first seat body 10 of the frame 3, the second seat body 20 of the frame 3, the operating handle 31 and the rod 32) is a technique of the prior art, for example, the Chinese Patent Publication No. No. 200620059004, the principle of the pivotal structure has been described in detail, so it will not be repeated here. The main content of this creation relates to the connection between the first body 10 and the second body 20. The first body 10 has a first pivot seat 12, and the first pivot seat 12 has two first holes 121, each of which has an internal thread 122 therein. The second base 20 has a second frame seat 22 having two protrusions 222 and a notch 223 formed between the protrusions; The shank seat 22 further has two second holes 221 corresponding to the two first holes 121 respectively formed on the two protrusions 222. The folding device 1 has two pivots 80 respectively corresponding to the second holes 221, each of the pivots 80 having a yaw thread 81 corresponding to the internal thread 122 in the first hole 121, respectively. . The folding device 1 has two bushings 70, which respectively correspond to the second holes 221; each bushing 70 is annular and has a flange 71; the preferred bushing 70 is an automatically lubricated shaft The liner 70 is used to ensure smooth operation when the shaft 70 is in use. Each of the bushings 70 of the M412916 is mounted in a corresponding second hole 221 for ensuring accurate position while preventing the bushing 70 from being excessively inserted. The first pivot seat 12 is placed in the notch portion 223 and is aligned with the second pivot seat 22, so that the first frame pivot seat 12 and the second pivot seat 22 are mutually concavo-convex. Hehe. The pivot 80 is inserted through the corresponding first hole 121, the bushing 70 and the second hole 221; since each of the first holes 121 has an internal thread 122, and each pivot 80 has a pivot Thread 81, so each pivot 80 can be fastened to its corresponding first hole 121. In addition, in the present embodiment, each of the bushings 70 is disposed on the protruding portion 222, please refer to FIG. 5; therefore, the bushing 70 is separated by the length L1 of the notch portion 223; Preferably, the L1 is preferably between 10 millimeters (mm) and 150 millimeters; if the folding device 1 is applied to the frame 3, the preferred length L1 may be between 20 and 150 millimeters; however, once The folding device 1 is applied to the handle frame 2, and the folding device will become smaller in use, and the preferred length is between 10 and 60 mm. Theoretically, when the torsion force of the folding device 1 is applied, the center line of the pivot 80 will have a moment (FXL) action; however, in reality, the moment will act at the position closest to the pivot 80; According to this embodiment, the closest position is located in the vicinity of the two bushings 70. Therefore, the moment force of the folding device can be predicted, however, this involves standard manufacturing techniques, so that a little wear is applied to the folding device. 1 to affect its service life; therefore, the quality of the folding device 1 is closely related to the age used; further, since the pivot 80 is replaceable, when the bushing 70 is damaged by the wear The bushing 70 can also be removed, making the folding device more durable and without having to replace the whole; further, the bushing can be used with 7 M412916 to prevent the steel pivot 80 from directly touching the aluminum part of the folding device 1. In order to prevent the steel pivot 80 from getting stuck in the aluminum part. The above-described embodiments are merely illustrative of the principles and effects of the invention and are not intended to limit the scope of the invention. Any person skilled in the art can make modifications and variations to the embodiments without departing from the spirit and scope of the invention. The scope of the present invention should be as described in the following claims; for example, the concept of the present invention can be applied not only to a four-link set but also to a three-link set, such as U.S. Patent Nos. 7,762,570 and 6,336,649. It should be noted that although the folding device 1 utilizes a pair of frame shafts 80 and a pair of corresponding bushings 70, the two can be simply changed to a single one.

New description: [New technology field] The company is a folding bicycle, especially a folding bicycle. [Prior Art] A bicycle that has at least a foldable component and a transmission device to achieve a smaller assembly size. Medium folding: τ makes the rear wheel folded 'relatively also reduces the assembly = the folding system uses the way to fold the steering assembly downwards: the traditional folding bicycle usually folds in at least one folding position, the device 'folding device The system includes a first seat body, a second seat body, a pivot shaft and an operating handle. The first body and the second system are approximately horizontal and are welded to each of the two halves of the frame; the extension of the base and the handlebar or the rear handlebar and the frame may be made of aluminum or alloy. The pivot is made by being machined so that it can be tightly wound, and the first and second bases are kneaded, and the pivotal suspension is made of steel. When the operating handle is closed, the folding device remains closed in the riding state; when the operating handle is opened, the folding device is opened to form a folded state. When the folding device is used and operated, since the metal parts will wear directly to each other, the pivot may damage the first seat body and the second seat body. Once held, the following things will occur: the folding device will become loose and weak. In addition, the torsional force formed by the frame will cause stress points on the pivot, so M412916 revised the replacement page on May 23, 100. _ · A "〇〇CI diagnosis of folding device and frame life It will be limited by such wear; once the folding device becomes loose, the increase of the torsional force may cause the pivot to bend or even be broken, and the vibration will cause the folding device to make a noisy sound and accelerate the wear of the folding device; Ground, when the pivot and seat system are made of different metals, 'usually softer metal (for example: ls), which is usually used on the f-frame: the harder metal that will be applied to the pivot ( For example: steel) to the rub and again, when they touch each other directly 2 can be stuck" because the cabinet pumping and bicycle frame synthesis 4 genus = = replaced with a large amount of gold may be inconvenient At the same time frame Losing the work will add to the environmental problem. In addition, in theory, when the torsion (produced by the force of riding) is applied to the folding device of the bicycle, the bending force bear will act by the center line; however, these are Assume that in the perfect shape, the bending moment will be the first to pass through the position closest to the axis (pivot). Due to the manufacturing accuracy, the position of the end of the pivot is estimated to be L-predicted. Therefore, some The folding device of the folding bicycle is easily damaged by the belt. Therefore, there is a need for an improved folding bicycle folding device to reduce or eliminate the above problems. [New content] The main purpose of the shaft is to reduce Another purpose of the pivotal creation of the two-piece joint is to easily maintain the folding device. In order to achieve the above object, the folding bicycle of the present invention includes a first seat and a second seat. Body, a locking device, at least one shaft and at least one pivot.
