The structure of first connecting rod system and second connecting rod system is identical, is that example is described its detailed construction with the first connecting rod system only below.As Figure 1-3, the first connecting rod system comprises two vertical link 7 that are separately positioned on top board 4 two ends, the upper end portion of this connecting rod 7 is hinged with the extension 5 of top board 4 by first bearing pin 6, and its underpart is hinged with first connecting plate 8 of substantially horizontal by second bearing pin 61.Described first connecting rod system comprises that also the level that is arranged on the base plate 1 is to pivot 10 and second connecting plate 9, a wherein end of second connecting plate 9 and first connecting plate, 8 quadratures welding, the other end and base plate 1 are hinged to pivot 10 by level, like this, second connecting plate 9 only can rotate to pivot 10 along fore-and-aft direction around level.Above-mentioned level to pivot 10 axially and the first connecting rod system parallel with the projection line of second connecting rod system on base plate 1, the parallel to an axis of first bearing pin 6 and second bearing pin 61 and vertical with the projection line of second connecting rod system on base plate 1 with the first connecting rod system.
In interchangeable embodiment, the radical of above-mentioned vertical link 7 can be three, four, and is perhaps more, but they all are arranged between base plate 1 and the top board 4 in parallel to each other by first bearing pin 6 and second bearing pin 61.
In addition, first connecting plate 8 and second connecting plate 9 can be made integral body, and its section configuration is not limited to rectangle shown in Figure 2, the Any shape that it can adopt those skilled in the art such as circular arc for example to expect, as long as the elongation line of two end is vertical mutually, can guarantee level axial vertical to axial and first bearing pin 6 and second bearing pin 61 of pivot 10 like this.
As shown in Figure 4, be the enlarged diagram of the resilient member that can vertically stretch of the present invention, the roller that it comprises sleeve 3, cardan shaft 2 and is assemblied in cardan shaft 2, wherein the bottom of cardan shaft 2 contacts with base plate 1 by roller.Fig. 5 is the sectional view of this resilient member, it comprises inner sleeve 12, spring 14 and outer sleeve 15, wherein seal by rubber seal 13 between inner sleeve 12 and the outer sleeve 15, the upper end of inner sleeve 12 is connected with top board 4 by guide rod 11, the lower end of outer sleeve 15 and cardan shaft 2 are fixing, and spring 14 is located between inner sleeve 12 and the outer sleeve 15.

Replacedly, vertical link 7 is by the hinged two-part connecting rod of the 3rd bearing pin 62, and this two-part connecting rod and waling stripe 71 are all hinged by the 3rd bearing pin 62.Like this, when earthquake took place, the amplitude of fluctuation of described device can be littler, the scope that also is the roller motion is dwindled (as shown in Figure 7), can make showcase and the inner historical relic motion amplitude thereof of apparatus surface little, and quickly recover to initial position, therefore have better effect.
As shown in Figure 8, be second embodiment of apparatus of the present invention.In this embodiment, except the roller that replaces among the embodiment one with slide block 21, miscellaneous part and mode of connection thereof are all identical.Slide block 21 has and the universal rolling wheel identical functions, and when earthquake took place, its resilient member that can support its top slided at any direction of horizontal plane.
As shown in Figure 9, be apparatus of the present invention the 3rd embodiment's perspective view.In this embodiment, except the spring spool 3 that replaces among the embodiment one with pendulum spring 31, miscellaneous part and mode of connection thereof are all identical.One end of pendulum spring 31 is fixedly connected on the middle part of top board 4, and the other end is in suspended state.Preferably, the initial length of this pendulum spring equates with distance between top board 4 and the base plate 1, and also, pendulum spring 31 contacts (as shown in figure 10) but not load-bearing with base plate 1.Under geological process, along with the height of top board 4 reduces, pendulum spring 31 is compressed and provides vertical support and restoring force, and its vertical rigidity can be to a certain extent seismic wave peak value isolator, and top board 4 remains level, and finally makes device progressively return to original state.
As the example of pendulum spring, can adopt helical spring, rubber spring or air spring, but also can adopt other that it may occur to persons skilled in the art that to be equal to means.This embodiment's advantage is: simple in structure, realize easily.
Need to prove, although in the above-described embodiments, top board 4 and base plate 1 be shaped as rectangle, it will be appreciated by those skilled in the art that it also can be circular, oval or other satisfies arbitrary shape of placing the historical relic demand.Under the situation of non-rectangle, as long as first connecting rod system and the second connecting rod system projection join line on base plate forms the function that rectangle just can be realized this device.
This device is with respect to the major advantage of prior art: this device is under the situation that adopts the spring spool resilient member, and its main isolation component is spring.For satisfying the vertical earthquake isolating demand, spring rate is less, yet because the confined air air lift between inner sleeve 12 and the outer sleeve 15 supplies additional restoring force (vertical support force), the distortion of geological process lower spring can be very not big.
The damping force of this device mainly by the resistance of air between the frictional force between sealing rubber ring 13 and the sleeve 15, inner sleeve 12 and the outer sleeve 15, second connecting plate 9 and level to the frictional force between the pivot 10, and the frictional force between connecting rod 7 and the bearing pin 6 provides.
More than explanation is just illustrative for the purpose of the present invention; and it is nonrestrictive; those of ordinary skills understand; under the situation that does not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence; as active roll is not changed, driven roller is arranged to hollow ventilation rubber roll, also will fall within protection scope of the present invention.
