Description

Three-dimensional shock insulation support with self-resetting function Technical Field The invention relates to the technical field of vibration isolation, in particular to a three-dimensional vibration isolation support with a self-resetting function. Background At present, protection of some valuables is gradually transferred to a shock insulation technology by a traditional shock insulation technology, wherein the shock insulation technology refers to that the to-be-protected items are installed on shock insulation equipment, and when an earthquake action occurs, the shock insulation equipment plays a role in reducing and insulating shock, so that the to-be-protected items are lightened or avoided from being damaged by the earthquake. Taking the patent document with the publication number of CN106381933B as an example, an anti-overturning composite spring three-dimensional shock insulation support is disclosed. The support mainly comprises an upper connecting plate and a lower connecting plate, wherein four inclined and four vertical 'pull rod back pressure type compound spring dampers' are arranged between the upper connecting plate and the lower connecting plate, and two ends of each damper are connected with the connecting plate through universal ball heads to jointly form a symmetrical quadrangular frustum pyramid structure. The basic working principle is that under the action of the horizontal force of an earthquake, the lower connecting plate generates displacement, so that part of the inclined damper is pressed and part of the inclined damper is pulled, and the energy is absorbed and dissipated through the expansion and contraction deformation of the spring. However, the energy dissipation mode depending on the reciprocating extension and contraction of the spring damper has the defect of low energy dissipation efficiency in practical application, and particularly, the spring damper mainly depends on material hysteresis deformation energy dissipation, has limited single-period dissipation energy, can reach a travel limit rapidly in the face of large displacement horizontal input during strong shock, and can cause energy dissipation saturation, residual energy is still transmitted to an upper structure, and the shock insulation effect is poor. Disclosure of Invention The invention aims to solve the problems in the prior art and provides a three-dimensional shock insulation support with a self-resetting function, and the energy consumption mode is changed to enable the energy consumption effect to be far higher than that of a conventional spring damper, so that a better shock insulation effect is realized.

According to the invention, a reset piece is arranged between the first seat body and the second seat body, so that after the first seat body descends, the reset piece is used for enabling the first seat body to have an upward reset movement trend. As a further scheme of the invention, the swing rod is divided into an upper part comprising a mounting end and a lower part comprising a damping end by taking the middle position of the swing rod as a limit, and the density of the lower part is greater than that of the upper part. As a further scheme of the invention, the top of the second seat body is provided with the energy-absorbing ring, the energy-absorbing ring and the swinging rod are coaxially arranged, and the inner ring of the energy-absorbing ring is positioned in the range of the swinging path of the swinging rod, so that when the second seat body moves horizontally due to an earthquake, the swinging rod which performs swinging action can abut against the inner ring of the energy-absorbing ring, and the energy-absorbing ring deforms to consume energy. As a further scheme of the invention, the limiting structure has a movable allowance which is suitable for the first seat body to do downward movement. As a further scheme of the invention, the limiting structure comprises two groups of upper connecting rods, two gro
