As shown in fig. 1 to 3, an embodiment of the present application discloses a damper mechanism including: damping ring 10, damping core 20 and connecting parts.

The shock absorbing ring 10 is injection molded from a rubber material, and the shock absorbing ring 10 has an oblong ring shape, which makes the shock absorbing ring 10 have an upper flat section 11 and a lower flat section 12. Since the middle portion of the damper ring 10 is of a hollow structure, this allows the entire damper mechanism to have a condition of absorbing vibrations of a large amplitude.

The damper core 20 includes two U-shaped plates 21, the two U-shaped plates 21 are fastened, that is, the notches of the two U-shaped plates 21 are opposite, so that the two U-shaped plates 21 enclose a long circular structure matched with the damper ring 10, and a preset fastening gap 22 is provided between the two U-shaped plates 21, which makes the enclosed long circular structure a split structure. The two U-shaped plates 21 are embedded in the damper ring 10, specifically, in the process of manufacturing the damper ring 10 using a rubber material, the two U-shaped plates 21 are integrally injection-molded with the damper ring 10, and the combining ability of the inside of the damper ring 10 with the U-shaped plates 21 is increased by fully distributing pits in the inner side plate surface and the outer side plate surface of the U-shaped plates 21. Preferably, the U-shaped plate 21 is formed from a spring steel plate by a hot-press bending process.

By embedding the two U-shaped plates 21 which are buckled in the shock absorption ring 10, the rigidity of the shock absorption mechanism can be further increased, and the shock absorption mechanism can be adapted to absorb the shock of large impact force.

The connection part includes an upper connection bolt 31 and a lower connection bolt 32; the upper connecting bolt 31 penetrates through the upper leveling section 11, the nut 311 of the upper connecting bolt 31 is stopped at the inner side of the upper leveling section 11, the lower connecting bolt 32 penetrates through the lower leveling section 12, the nut 321 of the lower connecting bolt 32 is stopped at the inner side of the lower leveling section 12, the side edges of the two ends of the U-shaped plate 21 are provided with arc-shaped notches 211, the arc-shaped notches 211 of the two U-shaped plates 21 enclose holes, the upper connecting bolt and the lower connecting bolt penetrate through corresponding holes, interference with the U-shaped plates 21 in the shock-absorbing ring 10 when the connecting bolt penetrates through the shock-absorbing ring 10 is avoided, and in addition, the diameter of the enclosed holes is larger than that of the connecting bolt.

As shown in fig. 4, the lower connecting bolt 32 is assembled with the support platform 102 by penetrating the support platform 102 and fitting the nut 60, and the upper connecting bolt 31 is assembled with the functional device 101 by penetrating the bottom of the functional device 101 and fitting the nut 60, so that the shock absorbing mechanism is assembled in place for absorbing shock generated by the device.

2. By making the two U-shaped plates 21 butt-buckled and providing the preset butt-buckling gap 22 between the two U-shaped plates 21, the long circular shock-absorbing core 20 is further formed into a split structure, which improves the ability of the shock-absorbing mechanism to absorb shock in the horizontal direction (it is known through experiments that if the shock-absorbing core 20 is provided as a closed long circular structure, the shock-absorbing mechanism has great rigidity in the horizontal direction and poor ability to absorb shock in the horizontal direction).

In some preferred embodiments, a cylindrical spring 40 is further added to the hollow structure of the upper and lower flat sections 11, 12 of the shock ring 10. Specifically, the screw cap 311 of the upper connecting bolt 31 is provided with a screw bolt 51, the screw bolt 51 is sleeved with a screw sleeve 52, the screw sleeve 52 is in threaded fit with the screw bolt 51, the screw bolt 51 is also sleeved with a locking nut 54, and the screw sleeve 52 is limited to rotate by screwing the locking nut 54; the screw sleeve 52 is formed with an upper positioning column 53; a lower positioning post 322 is formed on the nut 321 of the lower connecting bolt 32; the cylindrical spring 40 is disposed between the threaded sleeve 52 and the nut 321 of the lower connecting stud 51, and the upper positioning post 53 extends into the cylindrical spring 40 from the upper end of the cylindrical spring 40, and the lower positioning post 322 extends into the cylindrical spring 40 from the lower end of the cylindrical spring 40 to limit the lateral misalignment of the cylindrical spring 40 to be disengaged from the hollow structure. In this way, the compression amount of the cylindrical spring 40 can be adjusted by screwing the screw sleeve 52.

The above-mentioned shock absorbing mechanism additionally provided with the capability of adjusting the compression amount of the cylindrical spring 40 has the advantages that:

the stiffness of the damping mechanism in the vertical direction can be increased by adding the cylindrical spring 40, and more importantly: the whole damping mechanism can be adjusted in rigidity in the vertical direction by adding a structure for adjusting the compression amount of the columnar spring, and the resonance phenomenon of the functional equipment 101 and the damping mechanism can be effectively avoided by adjusting the rigidity of the damping mechanism.
