[0002] Interferometer is an optical device that uses the superposition of waves to obtain the phase information of waves, thereby obtaining the physical quantity of interest in the experiment. Interferometers are not limited to optical interferometers. They are widely used in astronomy, optics, engineering measurement, oceanography, seismology, spectrum analysis, quantum physics experiments, remote sensing, radar and other precision measurement fields. However, when using existing interferometers, the three sets of support legs are adjusted to a suitable angle for arrangement. Because the three sets of support legs can move independently, when the support legs of the interferometer encounter a little external force, the support legs will be displaced, resulting in the movement of the support legs, which will affect the overall stability of the interferometer and further affect the measurement accuracy. Utility Model Content
[0003] The purpose of the utility model is to provide a stable support interferometer. The device is used to work, thereby solving the problem that the existing support legs can move independently. Therefore, when using the interferometer, it is easy for one group of support legs to be displaced when encountering external force, resulting in the movement of the support legs causing the overall stability of the interferometer to be affected, thereby affecting the measurement accuracy.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stable support type interferometer, comprising an interferometer body, a movable plate fixedly mounted on the lower surface of the interferometer body, an adjustment support rod arranged on one side of the movable plate, a shock absorbing frame sleeved on the outer surface of the adjustment support rod, a main rod sleeved on the outer surface of the shock absorbing frame, an adjustment component for adjusting the length of the adjustment support rod arranged on one side of the main rod, and a support component for strengthening support fixedly mounted on one side of the main rod;

[0012] The utility model provides a stable support interferometer. When the interferometer is used, it is only necessary to pull open the main rod, and the flip plate will flip over at this time. When the upper surface of the flip plate contacts the lower surface of the limit plate, the support assembly will be fully opened. Because the three groups of main rods are fixedly connected to the support assembly, the support assembly improves the stability of the interferometer. Because the adjustment support rod is elastically connected to the shock-absorbing frame, the adjustment support rod cooperates with the shock-absorbing frame to reduce the influence of vibration on the interferometer. Finally, when the height of the interferometer needs to be adjusted, the fixing rod is pulled out of the adjustment hole, and the fixing rod is flipped over to allow the card plate to be stuck into the card slot. After the three groups are fixed, the adjustment support rod can be pulled, and then the fixing rod is flipped over again, and the fixing rod will return to the inside of the adjustment hole again, thereby achieving the effect of greatly improving the stability of the interferometer when in use.

A shock-absorbing spring 33 is fixedly installed on one side of the adjusting support rod 3. The adjusting support rod 3 and the main rod 4 can be folded through the circular hole 31, and the shock-absorbing spring 33 can also improve the shock-absorbing property of the interferometer body 1, thereby reducing the influence of vibration on the interferometer.
[0027] An adjustment hole 51 is provided on one side of the shock absorbing frame 5, a T-block 52 is fixedly installed on one side of the shock absorbing frame 5, a roller 53 is movably installed inside the T-block 52, a rod groove 54 is provided on the other side of the shock absorbing frame 5, the bottom of the rod groove 54 is fixedly connected to one end of the shock absorbing spring 33, a plate groove 55 is provided on the inner wall of the rod groove 54, the plate groove 55 is slidably connected to the slide plate 32, and the rod groove 54 allows the adjustment support rod 3 to have enough space for shock absorption.
[0028] A non-slip pad 42 is fixedly installed at the bottom of the main rod 4, a fixing hole 41 is opened on one side of the main rod 4, a rectangular groove 43 is opened at one end of the main rod 4, a T-shaped groove 44 is opened on the inner wall of the rectangular groove 43, the T-shaped groove 44 is adapted to the T-shaped block 52, and the adjustment hole 51 is adapted to the fixing hole 41. The non-slip pad 42 can improve the stability of the interferometer body 1 when it is in use.
[0029] The adjustment assembly 6 includes a connecting plate 61 fixedly installed on one side of the main rod 4, a circular groove 62 opened on one side of the connecting plate 61, a slot 64 opened on the lower surface of the connecting plate 61, and a fixing rod 69 arranged inside the circular groove 62, and the fixing rod 69 is adapted to the fixing hole 41. Through the relationship among the fixing rod 69, the fixing hole 41 and the adjustment hole 51, the overall height of the interferometer body 1 can be adjusted.
[0030] The adjustment assembly 6 also includes a handle 63 fixedly mounted on one side of the fixing rod 69, a card plate 65 fixedly sleeved on the outer surface of the fixing rod 69, the card plate 65 is adapted to the card slot 64, a bearing 66 fixedly sleeved on the outer surface of the fixing rod 69, a base plate 67 fixedly sleeved on the outer surface of the bearing 66, and a compression spring 68 fixedly mounted on one side of the base plate 67, one end of the compression spring 68 is fixedly connected to the inner wall of the main rod 4, and can be fixed at the same time through the card slot 64 after the height adjustment of the three groups of adjustment support rods 3 is completed.
[0031] Working principle: When the interferometer needs to be used, only one set of main rods 4 needs to be pulled, and the remaining two sets of main rods 4 will be opened synchronously. As the flip plate 73 rotates, when the surface of the flip plate 73 contacts the lower surface of the limit plate 76, the three sets of main rods 4 will be fully opened. Then, because the support assembly 7 moves up and down, the stability of the interferometer can be greatly improved. When the interferometer encounters external vibrations, the shock-absorbing spring 33 on the lower surface of the adjusting rod 3 will dampen the interferometer, thereby further improving the stability of the interferometer and the measurement accuracy. Finally, when the height of the interferometer needs to be adjusted, it only needs to be adjusted one by one. The fixing rod 69 is flipped over so that the card plate 65 on the outer surface is inserted into the card slot 64. At this time, one side of the fixing rod 69 is detached from the adjustment hole 51. Then the adjustment support rod 3 is pulled, and the shock absorbing frame 5 can be adjusted up and down inside the main rod 4. When the height of the interferometer is determined, the fixing rod 69 can be flipped over in the opposite direction to disengage the card plate 65 from the card slot 64. At this time, the fixing rod 69 will be reset by the compression spring 68, allowing one side of the fixing rod 69 to enter the adjustment hole 51. At this time, the height adjustment of the interferometer is completed, which greatly improves the stability of the interferometer during use.
