AI Technical Summary
In the existing seismometer, the fulcrum of the universal lever is in the middle, resulting in inconsistent movement directions at both ends of the lever. Two universal leveres need to be connected in series to avoid changing the direction, and the structure is complex.
Use a universal leverage as a magnifying device, and use the sphere and heavy blocks in the inductive device. The sphere is scattered on the ground motion instrument base. The overweight is empty and rotates.
The combination of the pillar of the ground motion instrument with a simpler structure, the design of the magnifying device effectively enlarges the displacement of the earthquake and improves the induction accuracy of the mobilization instrument.

Abstract
Description
Technical Field
[0001] The utility model relates to a column combination of a seismograph, in particular to a universal lever (also called space lever) amplifying device in the same direction. Background Art
[0002] In the previous patent application (application number 2024100944971), the connection method of the sensing device and the amplifying device of the double-column combination is up and down connection, and the amplifying device is two universal levers. Because the fulcrums of the two universal levers are in the middle, the movement directions of the two ends of the levers are inconsistent, and the two universal levers need to be connected in series to prevent the direction from changing. Summary of the invention
[0003] The purpose of the utility model is to provide a column combination with a simpler structure.
[0004] Technical solution: The column combination of the seismometer provided by the utility model includes a sensing device and an amplifying device, and the amplifying device is a universal lever in the same direction.
[0005] Furthermore, the sensing device includes a sphere and a weight. The spheres are scattered on the base of the seismometer, and the weight sits on the spheres. The displacement generated by the rolling of the spheres can sense ground vibration. There is a hole in the center of the weight that runs vertically and horizontally, which allows the universal lever to pass through and rotate.
[0006] Furthermore, the universal lever includes a counterweight, a fixed groove, a rotating ring, and a straight column with a horizontal bar; both ends of the rotating ring are connected to the weight block and can rotate around the connection point; both ends of the horizontal bar of the straight column with a horizontal bar are connected to the rotating ring and can rotate around the connection point; the two rotating axes are perpendicular to each other; the fixed groove is fixed at the center of the seismometer base, and the lower end of the straight column with the horizontal bar is a rocket head-shaped protrusion, which is connected to the fixed groove, and the connection point is the fulcrum of the universal lever.

[0011] The present invention is further described below through specific implementation methods and drawings. The embodiments are used to illustrate the present invention and are not intended to limit the present invention in any way.
[0012] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.
[0013] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0014] like Figure 1 As shown, the column assembly of the seismometer of the utility model comprises a sensing device and an amplifying device, and the amplifying device is a universal lever in the same direction.
[0015] like Figure 1 , 2 As shown, the sensing device includes a sphere 2 and a weight 3. The sphere 2 is scattered on the base of the seismometer, and the weight 3 sits on the sphere 2. The displacement generated by the rolling of the sphere 2 can sense ground vibration. There is a hole in the center of the weight 3 that runs through from top to bottom, which allows the universal lever to pass through and rotate.
[0016] like Figure 1 , 2 As shown, the universal lever includes a counterweight 5, a fixed groove 6, a rotating ring 7, and a straight column with a horizontal bar 8; both ends of the rotating ring 7 are connected to the weight block 3 and can rotate around the connection point; both ends of the cross bar of the straight column with a horizontal bar 8 are connected to the rotating ring 7 and can rotate around the connection point; the two rotating axes are perpendicular to each other; the fixed groove 6 is fixed at the center of the seismometer base, the lower end of the straight column with a horizontal bar 8 is a rocket head-shaped protrusion, which is connected to the fixed groove 6, and the connection point is the fulcrum of the universal lever; the length of the straight column at the upper end of the cross bar of the straight column with a horizontal bar 8 is times that of the lower end (in this embodiment, the ratio of the upper and lower lengths is selected as 10:1, respectively, and other ratio combinations can also be selected); the counterweight 5 is fixed under the cross bar of the straight column with a horizontal bar 8, so that the center of mass moment of the lower end of the straight column with a horizontal bar 8 is greater than that of the upper end.
[0017] like Figure 1 , 2 As shown, when an earthquake occurs on the right and propagates to the left, the base of the seismometer is driven by the ground, and the weight 3 remains stationary due to inertia. However, because the sphere 2 moves to the right relative to the base of the seismometer, the straight column 8 with the horizontal bar is driven to rotate clockwise, and the displacement caused by the earthquake induced by the weight 3 is amplified in the same direction (in this embodiment, it is amplified by 10 times).
[0018] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
