Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a rail transit shock absorber with multi-stage shock absorption. Background Art

[0002] Rail transit is a transportation system whose operating vehicles need to run on specific tracks. This transportation system not only includes long-distance land transportation, but is also widely used in medium- and short-distance urban public transportation. In rail transit, shock absorbers play an especially important role because they can significantly reduce the vibration of ground buildings when the train is running, improving the smoothness of the train's travel. Therefore, rail transit shock absorbers are needed. However, current rail transit shock absorbers still have the following shortcomings:

[0003] For example, the patent document with application number 202121579573.6 discloses a rail transit vehicle body shock absorber and noise reducer with an anti-collision structure. In the process of the rail transit vehicle running, if the fixed connection between the base and the rolling component partition becomes loose, the base can still be fixed by the outer limit block to the limit plate, which can reduce the probability of the device shifting or falling off and colliding with the track or vehicle body during use. However, the shock-absorbing and buffering effect of its shock-absorbing mechanism during use is limited, and it is not easy to maintain continuous stability in actual use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a rail transit shock absorber with multi-stage shock absorption is proposed. Utility Model Content

[0023] The specific operation is as follows. During use, when the supporting base plate 4 is pressed downward by force, the movable support rod 305 is pressed downward by the movable part 306, and the lower end of the movable support rod 305 rotates downward around the fixed part 304. At the same time, the upper end of the movable support rod 305 also rotates around the movable part 306. When the movable support rod 305 is pressed downward, it drives the movable cylinder 302 to slide along the surface of the limiting cross bar 301, and then the shock-absorbing spring 303 is squeezed to a certain extent through the movable cylinder 302. The rebound force of the shock-absorbing spring 303 causes the movable cylinder 302 to reset, producing a certain shock-absorbing and buffering effect.

[0024] Please refer to Figures 1 to 2 The inner surface of the fixing part 304 is rotatably connected to a movable support rod 305, and the upper end of the movable support rod 305 is rotatably connected to a movable part 306, a supporting bottom plate 4 is installed on the upper surface of the movable part 306, and a limited bottom frame 5 is installed on the upper surface of the supporting bottom plate 4, and a movable supporting frame 6 is slidably connected to the inner surface of the limited bottom frame 5, a connecting top plate 7 is installed on the upper surface of the movable supporting frame 6, and a damping spring 8 is provided on the lower surface of the connecting top plate 7, the lower side of the damping spring 8 is connected to the upper surface of the supporting bottom plate 4, a mounting screw 9 is provided on the upper surface of the connecting top plate 7, and the upper end of the mounting screw 9 is threadedly connected to a mounting nut 10, an auxiliary opening 12 is opened on the upper surface of the mounting base 1, and mounting plates 13 are installed on the lower ends of the two side surfaces of the mounting base 1, and the surface of the mounting plate 13 is threadedly connected to the mounting bolts 14;

[0025] The specific operation is as follows: when in use, when the connecting top plate 7 is compressed, it will drive the movable support frame 6 to move downward along the inner surface of the limiting bottom frame 5, and at the same time press the damping spring 8 downward, and the damping spring 8 rebounds to produce a shock-absorbing and buffering effect. Insert the mounting screw 9 into the inner side of the mounting hole, rotate the mounting nut 10 to fix it, and fix the mounting plate 13 to the surface of the installation position through the mounting bolt 14.

The threaded support rod 1102 is fixed by connecting the fixing nut 1103 with the threaded connection at the lower end of the threaded support rod 1102.

[0028] In summary, if Figures 1 to 3 As shown, when using the multi-stage shock-absorbing rail transit shock absorber, first, the mounting support plate 1105 is sleeved on the mounting screw 9, and the mounting support plate 1105 is slid up and down along the surface of the mounting screw 9 to a suitable height according to the height of the installation position, and the threaded support rod 1102 is rotated to pass through the surface of the mounting support plate 1105 and move along the upper surface of the fixing frame 1101 to fix the height of the mounting support plate 1105, and the threaded support rod 1102 is fixed by connecting the fixing nut 1103 with the threaded connection at the lower end of the threaded support rod 1102, and then, the mounting screw 9 is inserted into the inner side of the mounting hole, and the mounting nut 10 is rotated to fix it, and the mounting plate 13 is fixed to the surface of the installation position by the mounting bolt 14.
