Description of the Invention: [Technical Field to Which the Invention Is Along] The present invention relates to a bicycle for a bicycle and an adjustment mechanism. In particular, it refers to a kind of shock absorber [Prior Art] Force refers to Figure 2, a bicycle with a simple shock absorber... for example, it mainly includes a seat tube η, and a rear seat adjacent to the seat #ιι The group 12 is connected to a lower group 13 and a bolt 14 which is threaded through the upper group η u and an elastic body 15 surrounding the bolt member 12 and the seat tube η. The .L i side elastic body 15 is a rubber. Hunting this, when the frame is stressed, the 11. physique 15 will be forced by the seat tube 11 and the rear upper fork group 12, in the process of elastic extension and 丄 丄 丄 Λ 坪 钿 钿The amplitude is absorbed to make the frame 1 reach the shock absorber effect. Since the elastic body 15 is crushed due to elastic fatigue after using for a period of time, the length of the elastic body 15 is smaller than the distance between the seat tube U and the rear upper group 12, and at this time, the seat tube j] ^ ^ SU or the rear group 12 is easy to be in the process of the frame 1 force, along the number: on the Du 7 a, the Ί Ί bolt 14 is relatively displaced to force the seat tube U The preset change between the rear and the lower group 13 and deformation due to the angle change not only affects the comfort during riding, but also adjusts the other parts of the frame to cause difficulty and trouble. 97. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a bicycle having a suspension adjustment mechanism that does not affect riding and enhances ride comfort. 200904694 ...The bicycle with the suspension adjustment mechanism comprises a frame, a :: group and an adjustment group. The frame has a seat tube, and a pair of adjacent to the seat tube: the upper group and the lower group. The suspension group has a strong mechanical office j.. elastic body disposed between the seat tube and the β-stereoscopic group. The adjustment group has an extruding member disposed between the elastic body of the seat tube, and the pressing member is displaceably positioned on the seat f relative to the elastic body, so that the elastic body is applied to the pressing member. Elastic deformation 0 The effect of the invention is that the deformation of the elastic body can be directly pressed by the pressing member, and the pressing member can be restored to the pre-pressure value without affecting the angle of the frame and the comfort during riding can be improved. Sex. [Embodiment] The detailed description of the preferred embodiment of the second embodiment of the present invention with reference to the preferred embodiment of the present invention and the other embodiments of the present invention will be apparent. Referring to FIG. 3 and FIG. 4', the first preferred embodiment of the bicycle with the suspension adjusting mechanism of the present invention comprises: - the frame 2, a suspension group 3, and - the adjustment is also 4 ° 〇 'The frame 2 has a The tube 21, the front frame group 22 adjacent to the seat tube 21 and extending forward, and a rear upper fork group 23 and a rear lower fork group 24 adjacent to the seat tube 21 and extending rearward. The seat tube 21 has a first joint 211 formed on one side of the seat tube 21 and facing the rear upper fork set 23. The rear upper portion is further provided with a second joint 231 formed at one end and facing the seat tube 21, and a screw portion 232 formed at the second joint 231. The screw portion 232 is a threaded section in this embodiment. 200904694 The suspension group 3 has a bolt 31 that is displaceably passed through the second joint 32 and screwed to the first joint 31, and a first joint 211 ' is disposed around the bolt 31 and disposed on the seat tube 21 An elastic body 32 between the second joints 23 of the rear upper fork group 23. 5 Xuan 5 weeks The entire group 4 has an forcing member 41 and a socket 42. The pressing member 41 is disposed between the second joint 231 of the rear upper set 23 and the elastic body 51, and has a screwing section 411 screwed to the screw joint 232 of the second joint 231, and faces the elastic A forced pressing section 412 of the body 32. The socket 42 is nested around the bolt 31 between the elastic body 32 and the pressing portion 412 of the pressing member 41. When the frame 2 is stressed, and the seat tube 2 is narrowed by the bolt 31 relative to the rear upper fork set 23, or the rear upper fork set 23 is narrowed relative to the seat 2 along the inspection piece 3, the elasticity The body 32 is forced by the first and second joints 211, 231 to absorb amplitude during the elastic expansion and contraction, so that the frame [reaches the shock absorber effect. Referring to FIG. 3 and FIG. 4 and FIG. 5, since the elastic body 32 is shortened due to elastic fatigue after using a section of the temple, it is only necessary to rotate the pressing member 41' to make the pressing member. The screwing section 411 of the 41 is displaced along the screwing portion 232 of the second joint toward the seat tube 21, so that the pressing portion 412^4 can squeeze the socket 42 to force the elastic member 32 to elastically deform, so that the elastic body 32 is transferred to the socket 42 and the first joint of the seat tube 21 to restore the preload value. 1 and FIG. 7 is a second preferred embodiment of the present invention, which is substantially the same as the first preferred embodiment, except that the seat tube 21 of the frame 2 has a first joint formed on the first joint. 2 ι 19049044 and facing the screw portion 212 of the elastomer 32. The screw portion 212 is a screw hole in this embodiment. . The bolt 31 of the quasi-shock group 3 is threaded through the first joint 211 of the seat tube 21 and is screwed with the second joint 231 of the rear upper group 23. The screwing section 411 of the adjusting member 4 is screwed with the screw hole 212 of the first joint, and the socket 42 is disposed around the bolt 31 at the first joint 211 and the elastic body. 32 rooms. Referring to FIG. 6 and FIG. 7, the elastic body 32 is shortened due to elastic fatigue, and the pressing member 41 is also required to be rotated, so that the screw Q & 411 of the forced extrusion section is along the first The screwing portion 212 of the joint 211 is displaced toward the rear upper group 23, so that the pressing portion 412 can force the socket 42 to force the elastic body 32 to be elastically changed, and the station is produced/Pingwang 2 The elastic body 32 is forced to restore the preload value by the second joint 23 1 of the group 23 after the seat 42 has been lowered. It can be seen from the above that the bicycle with the suspension adjusting mechanism of the present invention has the following advantages and effects: The present invention directly forces the elastic body 32 by the dancing extruding member 41 without affecting the angle of the frame 2. The elastic deformation is used to restore the preload value, so that the frame 2 can maintain the preset angle 'to achieve the best suspension comfort. However, the above is only a preferred embodiment of the present invention, and if not, it is intended to limit the implementation of the present invention, that is, the simple equivalent change of the patent and the description of the invention according to the present invention. And modifications are still within the scope of the invention patent. 200904694 π 月 般 具有 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 简易 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图 图3 is a front view showing a first preferred embodiment of the present invention with a suspension adjustment; FIG. 4 is a cross-sectional view of the first preferred embodiment; Is a cross-sectional view of an elastic body; FIG. 6 is a front view showing a second preferred embodiment of the bicycle having the suspension adjusting mechanism of the present invention; FIG. 7 is a cross-sectional view of the second preferred embodiment; Fig. 8 is a cross-sectional view showing the forced extrusion of an elastic body in the second preferred embodiment. 200904694 [Description of main component symbols] 2 ..........Frame 21 .........
