For a single damper spring 3, the damper spring 3 is arranged in a plurality of parallel ways including: 1. one of the two ends of the damper spring 3 is connected to the second regulating member 22 to be connected to the first mounting member 11 through the regulating member 2, the other of the two ends of the damper spring 3 is connected to the second mounting member 12, and the other of the two ends of the damper spring 3 is not connected to the second mounting member 12 through the regulating member 2; 2. one of the two ends of the damper spring 3 is connected to the second adjusting member 22 to be connected to the second mounting member 12 through the adjusting assembly 2, the other of the two ends of the damper spring 3 is connected to the first mounting member 11, and the other of the two ends of the damper spring 3 is not connected to the first mounting member 11 through the adjusting assembly 2; 3. one of the two ends of the damper spring 3 is connected to the second regulating member 22 to be connected to the first mounting member 11 by the regulating member 2, and the other of the two ends of the damper spring 3 is connected to the other second regulating member 22 to be connected to the second mounting member 12 by the other regulating member 2. Briefly, for a single damper spring 3, at least one of the two ends of the damper spring 3 is connected to the adjustment assembly 2.

It can be seen that the number of adjustment assemblies 2 is greater than or equal to the number of damper springs 3. It will be appreciated that the plurality of damper springs 3 may be arranged in the same or different manner.

When the second regulating member 22 is moved upward relative to the first regulating member 21 by the regulating locking mechanism 23, the height position of the upper end of the damper spring 3 connected to the second regulating member 22 is raised, and the height position of the lower end of the damper spring 3 is raised accordingly, the portion of the second mounting member 12 connected to the damper spring 3 is raised upward relative to the other portion, thereby regulating the placement posture of the second mounting member 12; when the second regulating member 22 is moved downward with respect to the first regulating member 21 by the regulating locking mechanism 23, the height position of the upper end of the damper spring 3 connected to the second regulating member 22 is lowered, and the height position of the lower end of the damper spring 3 is lowered, the portion of the second mounting member 12 connected to the damper spring 3 is deflected downward with respect to the other portion, and the placement posture of the second mounting member 12 is regulated.

For example, the vibration damping device 100 is described as being applied to the detecting apparatus 200, and it will be understood by those skilled in the art that the vibration damping device 100 may be applied to other apparatuses, and is not limited to the detecting apparatus 200.

In some embodiments, as shown in fig. 2 to 3, the outer peripheral side of the conductive member 51 is formed with a plurality of mounting grooves 51a, and the radial outer sides and the upper and lower sides of the mounting grooves 51a are respectively opened, so that the mounting grooves 51a may be formed with a part of the outer peripheral wall of the conductive member 51 recessed inward; each mounting groove 51a is used for accommodating one magnetic piece 52, when the conductive piece 51 and the magnetic pieces 52 move relatively, the change of the magnetic flux of the conductive piece 51 is more obvious, and the conductive piece 51 acts with the plurality of magnetic pieces 52, so that the current generated by the conductive piece 51 is more stressed by ampere force in a magnetic field, and the whole conductive piece 51 is uniformly stressed, therefore, the vibration damper 100 can absorb larger vibration, the vibration damper 100 is ensured to be fast and stable, and meanwhile, the groove wall of the mounting groove 51a cannot interfere with the magnetic pieces 52, and the installation of the conductive piece 51 and the magnetic pieces 52 is facilitated.

For example, in the example of fig. 2 to 3, the conductive member 51 is formed in a ring shape, the cross-sectional shape of the mounting groove 51a is U-shaped, and the mounting groove 51a is provided with one magnetic member 52 correspondingly; when the vibration damping device 100 is subjected to external vibration, the conductive member 51 and the magnetic member 52 move up and down relatively, the magnetic flux of the conductive member 51 is changed to generate current, the conductive member 51 receives ampere force under the magnetic field of the magnetic member 52, and the stress direction of the conductive member 51 is opposite to the movement direction so as to damp the vibration, thereby achieving the effect of absorbing the vibration of the vibration damping device 100.
