[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 3 and Figure 4 The anti-seismic assembly 3 includes a connecting block 31 slidably connected to the inner wall of the shock absorbing box 2, a placing plate 32 arranged on one side of the connecting block 31, and a shock absorbing spring 33 arranged at the bottom of the placing plate 32. The upper surface of the placing plate 32 contacts the bottom of the laser interferometer body 1, and one end of the shock absorbing spring 33 is fixedly connected to the inner wall of the shock absorbing box 2. The placing plate 32 is internally movably connected with an I-shaped block 34. The bottom of the I-shaped block 34 is fixedly connected to the inner wall of the shock absorbing box 2. The I-shaped block 34 is filled with sponge. The connecting block 31, the placing plate 32 and the shock absorbing spring 33 are assembled to The interior of the shock-absorbing box 2 can effectively reduce the vibration transmitted to the laser interferometer body 1, improve the shock-resistant performance, and ensure the stability of the laser interferometer. Because the internal movably connected I-shaped block 34 of the placement plate 32 allows the shock-resistant component 3 to adapt to the vibration conditions of the external environment more flexibly, thereby better playing a shock-absorbing role. The interior of the I-shaped block 34 is filled with sponge, which can further absorb vibration energy, reduce the impact of vibration on the laser interferometer, improve the shock-resistant effect, and better protect the normal operation of the laser interferometer in external vibration environments such as earthquakes.

[0025] The inner wall of the shock absorbing box 2 is provided with a slide groove 21, and the inner wall of the slide groove 21 is provided with a spring 22. One end of the spring 22 is fixedly connected to the bottom of the connecting block 31, which can help stabilize the position of the connecting block 31 and play a further shock absorbing role.

[0026] A buffer pad 4 is provided on the upper surface of the placement plate 32 , which can increase the friction force and absorb a certain amount of vibration, thereby reducing the impact of the vibration on the internal mechanical parts of the laser interferometer body 1 .

[0027] A clamping assembly 5 is provided inside the shock absorbing box 2, and the clamping assembly 5 includes a fixing block 51 arranged on the upper surface of the connecting block 31, a threaded rod 52 threadedly connected to the center of the fixing block 51, and a clamping block 53 arranged at one end of the threaded rod 52, which fixes the laser interferometer body 1 to increase stability.

[0028] One side of the clamping block 53 is provided with anti-slip grooves to increase friction.

[0029] The bottom of the shock absorbing box 2 is provided with an anti-skid foot pad 6 to increase the friction between the shock absorbing box 2 and the ground and prevent the shock absorbing box 2 from sliding when vibrating.

[0030] Specifically, the connecting block 31, the placement plate 32 and the shock-absorbing spring 33 are assembled into the interior of the shock-absorbing box 2, and then the laser interferometer body 1 is placed on the upper surface of the placement plate 32, and the upper surface of the placement plate 32 is provided with a buffer pad 4, so that it can not only increase the friction between the laser interferometer body 1 and the placement plate 32, but also absorb certain vibrations and reduce the impact of vibrations on the internal mechanical parts of the laser interferometer body 1. In addition, because the inner wall of the shock-absorbing box 2 is provided with a slide groove 21, the inner wall of the slide groove 21 is provided with a spring 22, and one end of the spring 22 is fixedly connected to the bottom of the connecting block 31, it can help stabilize the position of the connecting block 31 and play a further shock-absorbing role. At the same time, a clamping assembly 5 is provided inside the shock-absorbing box 2, and the clamping assembly 5 includes a fixed block 51 arranged on the upper surface of the connecting block 31, a threaded rod 52 threadedly connected to the center of the fixed block 51, and a threaded rod 52 arranged at one end of the threaded rod 52. The clamp block 53 is provided with anti-skid grooves on one side of the clamp block 53, so that the laser interferometer body 1 is fixed together with the clamp block 53, thereby increasing stability. Therefore, the anti-vibration component 3 inside the shock-absorbing box 2 can effectively reduce the vibration transmitted to the laser interferometer body 1, improve the anti-vibration performance, and ensure the stability of the laser interferometer. Because the internal movable connection of the placement plate 32 is connected with the I-shaped block 34, the anti-vibration component 3 can adapt to the vibration conditions of the external environment more flexibly, so as to better play the shock-absorbing role. The I-shaped block 34 is filled with sponge, which can further absorb vibration energy and reduce the impact of vibration on the laser interferometer, thereby improving the anti-vibration effect and better protecting the normal operation of the laser interferometer under external vibration environments such as earthquakes. In addition, the bottom of the shock-absorbing box 2 is provided with an anti-skid foot pad 6, which increases the friction between the shock-absorbing box 2 and the ground and prevents the shock-absorbing box 2 from sliding during vibration.
