New description: [New technical field 】 This creation is about bicycles, especially the rear irons and systems built on the rear end of the rear forks of the frame, so that the wheel of the bicycle can be adjusted in a secret way. [Prior Art] Press 'General In the rear hook structure of the bicycle needle, most of the joints are made with the wheel axle Anga (four) ear, and then welded to the rear end of the frame, because the frame design of the frame does not change. For mountaineering, cross-country, road racing, leisure, performance and general use, and also for men, women, youth, etc. M413637. "Years, etc., so that the assembly and installation of the assembly The method is also different. β - [New content] (The problem to be solved) If you follow the previous hook The form made with the lifting lug can only be used in the original frame because it can only be assembled and used in the original frame. This obviously cannot meet the needs of the user, especially the use of -_ It’s not ideal to add a car model. • (Technical means to solve the problem) The creator has this in mind, that is, with the long-term conception of the rear fork of the bicycle and the concept of the Betong. The frame rear fork structure of the adjustable bicycle track is formed, and an elliptical large hole groove and a notch provided by the elliptical large hole groove are respectively arranged at the rear iron of the rear end of the rear fork, and the utility model comprises: In the two gaskets, each of the gaskets is provided with a clamping block, and the engaging block is provided with a fitting groove facing downward, and the two gaskets are installed on the rear iron, and the fitting grooves of the two gaskets Attached to the same axis; and further comprising: two additional pads, wherein each of the other gaskets is provided with a snapping block, and the engaging block is provided with a fitting groove facing downward, and the two other gaskets are mounted When the rear iron is disposed, the fitting grooves of the two other gaskets are on the same axis, but the axis and the upper The axis of the request item is located at different positions, thereby adjusting the length of the wheel of the bicycle; wherein one side of the gasket and the other gasket may be provided with a small bump, and the small bump is corresponding to the A small groove is formed in the elliptical large hole groove of the rear iron of the fork end; and a fixing screw is arranged on the other side of the gasket and the other piece. The main frame of the bicycle is provided after the frame of the wheel can be adjusted. The purpose is to provide a post-iron structure. The secondary purpose of this creation is to provide a safer post-iron peak. The wheelbase is adjustable after the frame. The purpose is to provide easy铋之-种_ Bicycle track after the frame and then the iron structure. (According to the previous technology to achieve the effect) Xiong from the above description, 'this creation has the following many effects · · 1, the creation of each other t The padding shape is corrected, and the effect of adjusting the bicycle track is generated. In particular, the long track of the bicycle can increase the stability of the car, and the basin 2 can increase the row of the beach, and the thinner can be used for the sideways to replace the pad. ;{And another gasket, increase the bicycle Use elasticity. The two cymbals created by the gamma and the other ones are respectively arranged, the engaging blocks, and the engaging blocks; the ridges are thicker, and the notches of the elliptical large holes that are engaged with the rear iron can be smashed. Wang Cheng X and the rear wheel of the cut bicycle, the car safety. ...3, the two pieces of the creation and the other gaskets - each side - small bumps, the other side " and the screw 4' hole' so only two screws can be used to two pieces or another The piece is fixed on the back X side of the self, and the wire can be added. [Embodiment] The creator's purpose and concept for the full implementation of the book will be described as follows: Please refer to Figures 1 and 2, which is about an adjustable bicycle. The preferred embodiment of the frame is comprised of m, two: 3 and two fixing screws 4; wherein the two slats 2 have the same shape. In addition, the shape of the two spacers 2 and the engaging blocks 20 thereof must be combined with the bicycle! The elliptical large hole groove 1 2 !_ of the rear iron 12 of the worker corresponds to the notch 1 2 4 provided, which means that the engaging block 20 of the one piece 2 can be respectively placed in the two elliptical large a notch 12 4 is disposed in the slot 121, and the engaging block 2 is further provided with a fitting groove 21 facing downwards, and the funnel groove 21 is asymmetrically disposed on the spacer 2, and the two spacers 2 when the rear iron 12 is installed, the fitting grooves 21 of the two spacers 2 are on the same axis 2 4; it should be particularly noted that one side of each spacer 2 is provided with a small bump 2 2 corresponding to The small groove 12 2 of the elliptical large hole groove 121 of the rear iron 12 of the rear 11 of the frame, and the other side of each spacer 2 are provided with screw holes 23, which are specially provided for fixing screws 4 The front end is disposed on the rear fork 11 and the iron 12 is provided with a fixing hole 12 3 and then screwed to the cymbal 2 ' so that the spacer 2 can be firmly combined with the rear 11 rear iron 12; The shape is basically the same as that of the spacer 2, which means that the engaging block 30 provided by the other two spacers 3 can be respectively inserted into the two elliptical large hole slots 121 of the rear iron 11 and the notch 12 of the rear iron 11 4, the engaging block 30 is provided with a fitting groove 31 facing downward and The fitting groove 31 is asymmetrically disposed on the other gasket 3, and when the two gaskets 3 are mounted on the rear iron 12, the fitting grooves 31 of the two gaskets 3 are on the same axis 34. (As shown in Fig. 3), and one side of each of the spacers 3 is provided with a small bump 3 2 corresponding to the small groove 12 2 ' of the elliptical large hole groove 12 1 of the rear iron 12 of the frame rear fork 11 In addition, the other side of each of the other gaskets 3 is provided with a screw hole 3 3 '. The screw hole 33 is specially provided for the front end of the fixing screw 4 to be worn by the rear fork of the rear ironwork 2 after the solid hole 1 2 3 In addition, the gasket 3 can be firmly combined with the rear iron 12; the biggest difference between the two gaskets 3 and the two gaskets 2 is that the fitting groove 3 1 of the gasket 3 is Not on the same axis, line, that is, the axis 34 of the above-mentioned pad 2 is located at the non-marriage position, so that the wheel of the bicycle can be adjusted when the second piece 2 and the second pad 3 are replaced. Distance; a plurality of fixing screws 4, when the two cymbals 2 or two cymbals 3 are provided with the engaging blocks 2 〇; 30 points of the person in the frame rear fork! When the inside of the notch i 2 4 of the two-sided large hole slot 21 of the iron i 2 is inserted, the front end of the fixing screw 4 is passed through the fixed W 2 3 of the iron 1 2 after the completion of the screw, and then screwed to the second piece. 2 or 2 additional spacers 3, and the second cymbal sheet 2 or the second cymbal sheet 3 is easily gorged on the shovel 2 after the qi; as shown in Fig. 4, by the composition of the above components, The cymbal 2 is fixed in the _ large hole slot i 2 后 of the rear fork 1 1 of the bicycle i 2 , and the small bump 2 2 of the second piece 2 is engaged with the _ large hole slot i 2 i of the rear iron i 2 The small concave 2 2 'after the fixed screw 4 will lock the second piece 2 to the rear iron i ^, at this time the bicycle is ii 彳 彳 i 2 贱 自行 自行 自行 转 转 转 转 转 转 后Axis and bicycle (four) speed components; if the second correction 2 system is a long track, then replace the other two pieces 3 lock compound α! money i short touch, meaning that the two other pieces 3 for the county set in the post iron At 12 o'clock, the fitting grooves 31 of the two other spacers 3 are on the same T3 4 'but the wires 34 are located at different positions and away from the front wheel axis ^; therefore, the lion and the m can be maneuverable Ground - the wheel track of the self-propelled car, especially the short track has improved flexibility for the bicycle The M413637 is suitable for mountaineering or tripping; the long track has a long-distance pair and is ideal for long-distance breaks on bicycles. ‘The above _, the structure of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _隹 专 专 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The spirit of the coverage should be combined with Chen Ming in this creation.
