[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a seismic resistant structure of an infrared detector. Figure 1-3 , an anti-seismic structure of an infrared detector, comprising a flange base 1, a detector body 8 mounted on the top of the flange base 1 through a supporting mechanism, the supporting mechanism comprising a limit frame 2, a movable ring 3 and a mounting platform 6, the limit frame 2 is fixedly connected to the top outer wall of the flange base 1, the movable ring 3 is slidably connected to the inner wall of the limit frame 2, the mounting platform 6 is fixedly connected to the top outer wall of the movable ring 3, the bottom outer wall of the movable ring 3 is fixedly connected with a plurality of first springs 4, the bottom ends of the plurality of first springs 4 are fixedly connected to the top outer wall of the flange base 1, the detector body 8 is fixedly connected to the top outer wall of the flange base 1, and the detector body 8 is fixedly connected to the top outer wall of the flange base 1 through a supporting mechanism. It is fixedly mounted on the top outer wall of the mounting platform 6 by multiple screws, multiple shock absorbers 5 are installed between the bottom outer wall of the mounting platform 6 and the top outer wall of the limit frame 2, a shock absorbing assembly is installed between the flange base 1 and the mounting platform 6, and the shock absorbing assembly includes a damping frame 11 fixedly connected to the bottom outer wall of the mounting platform 6, and the inner wall of the damping frame 11 is slidably connected to two movable blocks 12, and the outer walls opposite to the two movable blocks 12 are jointly installed with a damper 14, and the outer walls of the two movable blocks 12 facing the outside of the damping frame 11 are hinged with a connecting frame 10 through a fixed shaft 13.

[0022] The shock absorbing assembly further comprises two hinge blocks 9 fixedly connected to the outer wall of the top of the flange base 1 , and two connecting frames 10 are hinged to the outer walls of the two hinge blocks 9 at one end away from the connecting frame 10 .

[0023] The outer wall of the two movable blocks 12 at one side away from the damper 14 is fixedly connected with a second spring 15 , and one end of the two second springs 15 away from the movable blocks 12 is fixedly connected to the inner wall of the damping frame 11 .

[0024] A plurality of first springs 4 are evenly distributed between the flange base 1 and the movable ring 3 in a circular array at equal intervals.

[0025] A plurality of shock absorbers 5 are evenly distributed between the mounting platform 6 and the limiting frame 2 in a circular array with equal spacing.

[0026] A shock-absorbing pad 7 is arranged between the bottom outer wall of the detector body 8 and the top outer wall of the mounting platform 6 .

[0027] The implementation principle of the earthquake-resistant structure of an infrared detector in the embodiment of the present application is as follows: the flange base 1 is fixed to the ground or other fixed structures. When an earthquake or other forms of vibration occur, the ground or other fixed structures will transmit the vibration to the shock-absorbing assembly through the supporting mechanism. First, the limit frame 2 and the movable ring 3 in the supporting mechanism slide and retract, so that the movable ring 3 squeezes or stretches the multiple first springs 4, and the deformation of the multiple movable rings 3 can absorb most of the vibration energy. At the same time, the movable ring 3 drives the installation platform 6 to move, so that the installation platform 6 and the limit frame 2 squeeze or stretch the multiple shock absorbers 5. The shock absorbers 5 can suppress the elastic jump caused by the deformation of the multiple movable rings 3, so that the expansion and contraction amplitude of the limit frame 2 and the movable ring 3 is reduced, thereby avoiding direct impact on the shock absorber 5;

[0028] Then, when the vibration energy absorbed in the supporting mechanism is transmitted to the shock absorbing assembly, the limit frame 2 and the movable ring 3 are telescopically matched with the mounting platform 6 to drive the damping frame 11 to move up and down. At this time, the two movable blocks 12 will be pushed or pulled to slide relative to each other through the connecting frame 10. In this process, the two connecting frames 10 will rotate at an angle, and the two ends of the connecting frame 10 are respectively hinged to the fixed shaft 13 through the hinge block 9, so that the connecting frame 10 can cooperate with the rotation. When the two movable blocks 12 move relative to or away from each other, they squeeze or stretch the damper 14 and the second spring 15. The damper 14 and the second spring 15 will generate a damping force to attenuate the sliding amplitude of the two movable blocks 12, thereby further attenuating the telescopic amplitude of the limit frame 2 and the movable ring 3. Finally, in conjunction with the shock absorbing pad 7, the shock absorbing pad 7 can be made of damping materials such as rubber or plastic, so as to further absorb and disperse the remaining vibration energy, effectively protect the detector body 8 from damage, and ensure its normal operation.
