Detailed Description

The present invention will be described in further detail with reference to specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

A deflection structure capable of being rapidly and stably arranged comprises a deflection frame, a stabilizing assembly and a shell;

the deflection frame comprises a round top support 1, a round bottom support 2 which is coaxial with the top support 1 and has the same size with the top support 1, and a hanging basket frame 3 arranged between the top support 1 and the bottom support 2, wherein an annular bulge 4 is arranged in the middle of the top support 1, the annular bulge 4 is positioned in a top opening of the shell and has a gap with the top opening, and the top of the deflection frame deflects in the top opening of the shell;

the stabilizing assembly comprises a bottom stabilizing assembly and a top stabilizing assembly;

the bottom stabilizing assembly comprises a base 5 fixed at the bottom of the deflection frame, a fixed plate 6 fixed at the bottom of the shell, a radial spring group for pulling and fixing the base 5 at the periphery of the fixed plate 6 in a balanced manner, a support shaft 7 fixed at the lower surface of the fixed plate 6 and a support shaft socket 8 formed in the center of the base 5, wherein the end part of the support shaft 7 is in contact with the support shaft socket 8;

the top stabilizing assembly comprises a groove formed by enclosing the annular protrusion 4 and used for filling damping oil 9 and a vertical rod 11 fixed at the bottom of the positioning sleeve 10 and extending into the groove without contacting the bottom of the groove, and the positioning sleeve 10 is fixed in the top opening of the shell.

When the deflection structure is in a natural state, namely deflection does not occur, the vertical direction is kept under the action of the centripetal spring group. The centripetal spring group provides upward pulling force to the whole deflection structure, and the pulling force keeps balance with the whole gravity of the deflection structure. When the deflection structure is under the action of external force, the supporting shaft 7 provides a point-contact lower support for the deflection structure, so that the deflection structure can be ensured to be in a radial deflection along the direction of the external force under the action of the external force like an inverted simple pendulum by taking the contact point of the deflection structure and the lower support as a fulcrum.

The deflection structure instantaneously swings at the moment of external force action, and after the deflection occurs, the unstable deflection structure can shake due to the inertia action. In order to ensure the rapid stability of the deflection structure in measurement and relieve the fluctuation of the deflection structure in the measurement process, the deflection structure also comprises a top stabilizing component. The top stabilizing component comprises a groove formed by enclosing the annular protrusion 41 and used for filling damping oil 9 and a vertical rod 11 fixed at the bottom of the positioning sleeve 10 and extending into the groove without contacting with the groove bottom, wherein the vertical rod 11 and the damping oil 9 form damping, the vertical rod 11 does not contact with the groove bottom and reserves a space for the upward movement of the deflection structure. The damping oil is composed of special components with flexible retardation, and can reduce the shaking of the deflection structure and promote the deflection structure to be stable as soon as possible, thereby improving the measurement efficiency.

And the influence of external force impacting the lower deflection structure is avoided by means of the restraint action of the centripetal spring group on the deflection structure. In addition, by means of the constraint action of the centripetal spring group on the deflection structure, when the tested deflection structure is withdrawn after measurement is completed, the gravity of the whole deflection structure can be kept balanced, and the bearing of the deflection structure is realized, so that the reliability and the high efficiency of the measurement are ensured.
