It is further used as preferred embodiment, the horizontal seismic isolation mechanism includes lead-rubber seat 5, the lead-rubber
Seat 5 is fixed on the upper surface of housing 4.Horizontal seismic isolation mechanism uses lead-rubber seat 5, and lead-rubber seat 5 is in horizontal seismic isolation
In the process other than with better reset capability and endurance quality, moreover it is possible to have horizontal seismic isolation mechanism under plastic deformation circulation
There is good anti-fatigue performance.It of courses, horizontal seismic isolation mechanism, can also be using other water in addition to using lead-rubber seat 5
Flat seismic isolation technology scheme.
It is further used as preferred embodiment, the lead-rubber seat 5 is including lower sealing plate, upper sealing plate and is located at the two
Between laminated rubber, sandwich clad steel is equipped between the laminated rubber, is equipped with hollow mesoporous, institute in the lead-rubber seat 5
It states and is equipped with lead for retractable pencil in hollow mesoporous.Lower sealing plate, sandwich clad steel, laminated rubber and upper sealing plate by high temperature, that high pressure is sulfided into one is whole
The hollow mesoporous design of body, lead-rubber seat 5 is that expansion space is provided for sulfidation, can guarantee vulcanize in sulfidation in this way
Quality, and can guarantee the stabilization of lead for retractable pencil performance.Rubber in lead-rubber seat 5 uses soft natural rubber, rubber surrender
Rigidity afterwards is only the 67% of middle durometer rubber, makes the cycle stretch-out of isolation structure, and superstructure maximal acceleration effect reduces,
So that lead-rubber seat 5 has good anti-fatigue performance under plastic deformation circulation, increases the damping of support, and improve branch
Consumption of the seat to energy caused by external shock；In addition, the performance of lead for retractable pencil is stablized, lead for retractable pencil performance change after plastic deformation circulation
It is small.
It is further used as preferred embodiment, the lead-rubber seat 5 is fixed on the middle part of housing 4；The spring 3
There are more, the through-hole has multiple, and the guide rod 2 there are more, and the one-to-one correspondence of spring 3 is sheathed on outside guide rod 2, the guide rod
2 top is corresponded across through-hole；The through-hole is evenly spaced on around lead-rubber seat 5.Superstructure ballast
On lead-rubber seat 5, lead-rubber seat 5 is fixed on the middle part of housing 4, and the one-to-one correspondence of spring 3 is sheathed on outside guide rod 2, leads
The top of bar 2 is corresponded across through-hole, and more springs 3 are evenly spaced on around lead-rubber seat 5, is played preferably
Vertical damping effect.
It is further used as preferred embodiment, further includes loss prevention mechanism, the loss prevention mechanism includes more screw rods 61, more
Root screw rod 61 both passes through cavity 11, and more screw rods 61 extend through the front and back end of shell 1, left and right end, the both ends of the screw rod 61
It is equipped with the nut 62 abutted with 1 outer wall of shell；The upper housing 4 is equipped with downward opening, sets on the side wall of the upper housing 4
There is a plurality of sliding slot, the sliding slot extends along the vertical direction, and the width of the sliding slot is slightly larger than the outer diameter of screw rod 61.Horizontal seismic isolation machine
Structure will drive horizontal seismic isolation mechanism, upper housing 4 moves horizontally in horizontal vibration damping, and shell 1 damages in order to prevent, therefore be arranged anti-
Damage mechanism.Locking loss prevention mechanism includes screw rod 61, and multiple screw rods 61 both pass through cavity 11, and multiple screw rods 61 extend through shell 1
Front and back end, left and right end, the both ends of screw rod 61 are equipped with the nut 62 abutted with 1 outer wall of shell, 62 tie down screw 61 of nut, shell
1 front and back end, left and right end are locked by screw rod 61 and nut 62, prevent shell 1 from being supportted quick-fried.
It is further used as preferred embodiment, the top of shell 1 is arranged in the screw rod 61.Since cavity 11 is half envelope
Enclosed, the top of shell 1 be easier to support it is quick-fried, so screw rod 61 is arranged in the top of shell 1.
It is further used as preferred embodiment, further includes bottom plate 7, the edge of the bottom plate 7 is located at the outside of shell 1,
