Embodiment 1

[0082] The embodiment of the start-up control shock-isolation device of the preset start-up load of the present invention is as follows Figure 1 to Figure 17 As shown, the device includes an upper panel 3, a lower panel 2, a middle frame 4 and a shock-isolation elastic reset device with a preset starting load. The lower panel 2 is used to be placed on the floor or showcase panel or the ground. The upper panel 3 and the lower panel 2 are equipped with a wiring area 101 for power lines or data lines to pass through. The shock-isolation elastic reset device includes two sets of horizontal shock-isolation elastic reset mechanisms 1 and five sets of vertical shock-isolation elastic reset mechanisms 6. The elastic return mechanism 6 is located above the device. The device has both a horizontal shock-isolation elastic return mechanism 1 and a vertical shock-isolation elastic return mechanism 6, which can be combined to realize vertical and horizontal three-dimensional shock isolation...

Embodiment 2

[0114] The second embodiment of the start-up control shock-isolation device with preset start-up load in the present invention is as follows Figure 18 to Figure 20 As shown, the difference from Embodiment 1 is that the shock-isolation elastic return device of this embodiment only includes a horizontal shock-isolation elastic return mechanism, and does not provide a vertical shock-isolation elastic return mechanism, while omitting the connecting plate and the upper cavity.

[0115] In this embodiment, two sets of horizontal shock-isolation elastic return mechanisms are provided in the horizontal and vertical directions respectively, and four sets of horizontal shock-isolation elastic return mechanisms are erected on the side of the middle frame 4 in the shape of a well-shaped cross along the horizontal and vertical lines. Both ends of the shock-isolation elastic reset mechanism are fixedly connected with the middle frame 4 through guide rods 13, the first slider 16 in the horiz...

Embodiment 3

[0117] The third embodiment of the start-up control shock-isolation equipment with preset start-up load in the present invention is as follows Figure 21 to Figure 23 As shown, the difference from Embodiment 1 is that the shock-isolation elastic return device of this embodiment only includes a horizontal shock-isolation elastic return mechanism, and does not provide a vertical shock-isolation elastic return mechanism, while omitting the connecting plate and the upper cavity.

[0118] In this embodiment, the shock-isolation elastic reset mechanism is a horizontal shock-isolation elastic reset mechanism, and there are one set of horizontal shock-isolation elastic reset mechanisms along the horizontal and vertical directions. The horizontal shock-isolation elastic reset mechanism includes guide rod 13, stopper 15, spiral steel Spring 12, steel strand 22 and second slide block 23, guide rod 13 are horizontally arranged, and second slide block 23 is sleeved in the middle part of gui...

Abstract

The invention discloses a shock-insulating elastic returning mechanism with the preset starting load. The shock-insulating elastic returning mechanism comprises a guide rod, at least two stopping blocks and a preset starting load elastic unit; the stopping blocks are arranged on the guide rod in a sleeving manner; and the preset starting load elastic unit comprises a spiral steel spring, the spiral steel spring is arranged on the guide rod in the sleeving manner and between the stopping blocks, and the spiral steel spring is a pre-pressed spiral steel spring and has a pre-pressed length and the preset starting load. When an external load generated by shock is larger than the preset starting load, the spiral steel spring is started; thus, the shock-insulating elastic returning mechanism has the preset starting load function. The invention also discloses start-control shock insulating equipment with the preset starting load.

Description

technical field [0001] The invention relates to equipment in the anti-seismic field, in particular to a shock-isolation elastic reset mechanism with a preset start-up load and a start-up control shock-isolation device. Background technique [0002] As the most representative innovative structural anti-seismic technology in the last century, anti-seismic control technology provides new means and research directions for engineering anti-seismic disaster reduction. [0003] The horizontal seismic isolation structure system divides the structure into three parts: the upper structure, the seismic isolation layer and the lower structure by setting the seismic isolation layer. The seismic energy is transmitted to the seismic isolation layer through the lower structure, and is absorbed and consumed mainly After the seismic energy, only a small part of the energy is transmitted to the superstructure. The setting of the seismic isolation layer changes the natural vibration period of ...
