DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] The utility model provides the following preferred embodiments:

[0033] Embodiment 1, as Figure 1-Figure 7 As shown, a seismic design structure of a bimetallic thermometer includes a bimetallic thermometer body 11 and a measuring rod 12. The measuring rod 12 is installed at the bottom end of the bimetallic thermometer body 11. The measuring rod 12 is used to be inserted into the inside of a medium to detect the temperature of the medium. It also includes a first mounting seat 13, a plug hole 14 and a shock absorbing mechanism. The first mounting seat 13 is sleeved on the outside of the measuring rod 12. The plug hole 14 is opened in the middle of the first mounting seat 13. The measuring rod 12 is plugged into the inside of the plug hole 14. The inner diameter of the plug hole 14 matches the outer diameter of the measuring rod 12. When the bimetallic thermometer body 11 needs to be installed, the first mounting seat 13 is first installed at a suitable position, and then the end of the measuring rod 12 is plugged into the inside of the plug hole 14, so that the bimetallic thermometer body 11 can be installed and fixed;

[0034] The shock absorbing mechanism includes a plurality of abutment plates 17, a plurality of cavities 16, a plurality of elastic components and a plurality of smooth components. The plurality of abutment plates 17 are arranged in an annular shape and are equidistantly arranged inside the plug hole 14. A cavity 16 is provided on one side of each abutment plate 17 and inside the first mounting seat 13. Each elastic component is located between an abutment plate 17 and a cavity 16, and each smooth component is located between an elastic component and a cavity 16.

[0035] By providing a plurality of elastic components, when the measuring rod 12 vibrates under the impact of the medium, the deformation energy of the spring 31 is used to buffer and reduce the impact force, thereby reducing the amplitude of the lateral swing of the measuring rod 12 under the impact force, which is beneficial to improving the anti-seismic effect of the bimetallic thermometer body 11;

[0036] By setting up a smoothing component, when the spring 31 is deformed to buffer the impact force, the smoothing component can prevent the spring 31 from rebounding quickly, and reduce the speed at which the bimetallic thermometer body 11 shakes when the spring 31 rebounds, which is beneficial to improving the stabilization effect and preventing the bimetallic thermometer body 11 from shaking too quickly, thereby affecting the normal operation of the bimetallic thermometer.

[0037] like Figure 1-Figure 7 As shown, each elastic component includes a push rod 18, a sliding rod 19, two sliders 20, two hinged rods 21 and two springs 31. The sliding rod 19 is fixedly installed inside the cavity 16. The two sliders 20 are slidably arranged on both sides of the sliding rod 19. Specifically, a sliding bearing for reducing friction is arranged between the slider 20 and the sliding rod 19. The two springs 31 are respectively sleeved on both ends of the sliding rod 19. The two ends of each spring 31 are respectively fixedly connected to the cavity 16 and the slider 20.

[0038] The push rod 18 is fixed to one side of the abutment plate 17 close to the cavity 16, and the other end of the push rod 18 is inserted into the cavity 16. Specifically, a square hole is provided between the cavity 16 and the insertion hole 14 for the push rod 18 to pass through, and the push rod 18 is slidably arranged inside the square hole. One end of each slider 20 close to the push rod 18 is hinged to a hinge rod 21, and the other end of each hinge rod 21 is hinged to one end of the push rod 18 away from the abutment plate 17.

[0039] When the measuring rod 12 vibrates under the impact of the medium, the measuring rod 12 pushes the abutment plate 17 to move, and the abutment plate 17 pushes the push rod 18 to move. Under the action of the hinged rod 21, when the push rod 18 moves, it can push the two sliders 20 away from each other. At this time, the two springs 31 are deformed. The deformation energy of the spring 31 can buffer and reduce the impact force, thereby reducing the amplitude of the lateral swing of the measuring rod 12 under the action of the impact force, which is beneficial to improving the seismic effect of the bimetallic thermometer body 11.

[0040] like Figure 1-Figure 7 As shown, each balancing assembly includes four moving rods 25, four sleeves 22 and four pistons 23, and every two sleeves 22 are symmetrically arranged on one side of a slider 20, and each piston 23 is slidably arranged inside a sleeve 22;

[0041] A moving rod 25 is slidably provided at one end of each sleeve 22, and both ends of each moving rod 25 are fixedly connected to the piston 23 and the slider 20 respectively. A through hole 24 is provided on the surface of each piston 23. Specifically, the interior of the sleeve 22 is filled with hydraulic oil, and the diameter of the through hole 24 is relatively small.

[0042] During shock absorption, when the slider 20 moves, the slider 20 pushes the moving rod 25 to move, and the moving rod 25 can drive the through hole 24 to move inside the piston 23. When the through hole 24 moves, it can squeeze the hydraulic oil on the side of the through hole 24 away from the moving rod 25, so that the hydraulic oil on this side can enter the other side through the through hole 24. When the spring 31 completes a shock absorption and rebounds, the hydraulic oil close to the side of the moving rod 25 can flow back to the other side of the piston 23 through the through hole 24. Since the diameter of the through hole 24 is small, the piston 23 is prevented from returning too quickly, thereby avoiding the rapid rebound of the spring 31, reducing the shaking speed of the bimetallic thermometer body 11 when the spring 31 rebounds, which is beneficial to improving the stabilization effect.

[0043] like Figure 1-Figure 7 As shown, a fixing seat 26 for fixing the sleeve 22 is sleeved on the outer side of the sleeve 22. The fixing seat 26 is fixedly installed on the inner wall of the cavity 16. The fixing seat 26 is used to fix the sleeve 22 to prevent the sleeve 22 from moving synchronously when the piston 23 moves.

[0044] like Figure 1-Figure 7 As shown, two guide rods 30 are fixedly installed on one side of the abutment plate 17 close to the push rod 18. The two guide rods 30 are symmetrically fixedly installed on both sides of the push rod 18. Each guide rod 30 is slidably inserted into the inside of the first mounting seat 13. When the abutment plate 17 is displaced when the measuring rod 12 vibrates, the guide rod 30 can slide inside the first mounting seat 13 to play a guiding role, thereby ensuring the smooth operation of the abutment plate 17.

[0045] like Figure 1-Figure 7 As shown, a rubber pad 27 for improving the buffering effect is provided on the side of the abutment plate 17 away from the push rod 18 . The rubber pad 27 can improve the anti-vibration effect of the bimetallic thermometer body 11 .

[0046] like Figure 1-Figure 7 As shown, two rubber rings 15 are installed on the inner wall of the plug hole 14, and the two rubber rings 15 are respectively located at the two ends of the multiple abutment plates 17. By arranging the rubber pad 27 and the two rubber rings 15, not only the sealing effect between the bimetallic thermometer body 11 and the first mounting seat 13 can be improved, but also the rubber pad 27 and the rubber ring 15 have a certain elasticity, which is beneficial to improve the anti-seismic effect of the bimetallic thermometer body 11 and meet the use requirements.

[0047] like Figure 1-Figure 7As shown, a second mounting seat 28 is fixedly mounted on the bottom end of the first mounting seat 13, and a plurality of mounting holes 29 are equidistantly provided in a ring shape on the surface of the second mounting seat 28. By providing the second mounting seat 28 and the plurality of mounting holes 29, the first mounting seat 13 can be easily installed, and the bimetallic thermometer body 11 can be installed and fixed by plugging the measuring rod 12 into the plug hole 14, thereby achieving the effect of facilitating installation.
