When the external environment generates vibration, the impact energy of the up-and-down vibration is firstly absorbed by the first and second

flexible plates

6 and 8 at the top and the fourth

flexible plates

14, 16 and 18 at the bottom, so as to reduce the vertical amplitude, while the left-and-right vibration is absorbed by the third and first

flexible plates

10 and 12 at the left and right sides, and the first flexible plates 12 at the left and right sides shrink and release along with the vibration, so as to reduce the left-and-right amplitude. Meanwhile, as the vertical vibration is generated by the earthquake, the window frame 3 gives the downward impact force to the top plate 1807, the impact force is downwards conducted, the piston rod 1804 is pressed to downwards move to finally contact hydraulic oil and continuously downwards press the hydraulic oil, the hydraulic oil at the lower part of the oil cylinder body 1801 enters the oil guide pipe 1803 along the oil guide hole 1802 below and then upwards flows along the oil guide pipe 1803 and returns to the oil cylinder body 1801 along the oil guide hole 1802 above; because the throttle valve 24 is in the throttle position, the oil mass of the oil body flowing from the oil guide pipe 1803 in unit time is limited, the descending speed of the piston is slowed down, the residual hydraulic oil at the bottom cannot be emptied instantaneously, so that an upward supporting force is provided for the whole structure, part of kinetic energy contained in the impact force is absorbed and converted into internal energy, the temperature of the hydraulic oil is increased, the impact energy is decomposed, the vibration amplitude is reduced, when upward vibration starts, the spring 1805 rebounds upwards, the piston rod 1804 moves upwards, the hydraulic oil which is originally introduced from the upper oil guide hole 1802 to the upper part of the piston enters the oil guide pipe 1803 again from the upper oil guide hole 1802 and enters the space at the bottom of the oil cylinder body 1801, preparation is made for the next impact, and meanwhile, the first flexible plate 6 and the second flexible plate 8 which are positioned above the window frame 3 shrink in thickness to absorb the impact energy, and the vibration amplitude is further reduced.

Example 2

To further enhance the protection of the window frame 3, to prevent the side concrete wall 1 from excessively pressing the window frame 3 and causing excessive damage thereto, left and right

hydraulic damper mechanisms

26 and 27 identical to the upper hydraulic damper mechanism 18 are provided between the left and right window frames 3 and the third steel fixing plate 9, respectively; because left hydraulic damper 26 and right hydraulic damper 27 are placed in the level, all are located the top of hydro-cylinder body 1801 with leading oil pipe 1803 in the oil hole 1802 on left hydraulic damper 26 and the right hydraulic damper 27, prevent that the oil body of left hydraulic damper 26 and right hydraulic damper 27's the interior piston rod 1804 of hydro-cylinder body 1801 on piston body both sides circulate each other when not receiving the extrusion, influence normal use. When the side concrete wall 1 vibrates left and right due to an earthquake or other strong vibration, the left hydraulic damping mechanism 26 and the right hydraulic damping mechanism 27 are extruded, the oil bodies in the oil cylinder body 1801 are extruded to move from one side of the oil cylinder body 1801 to the other side, and the left hydraulic damping mechanism 26 and the right hydraulic damping mechanism 27 buffer and protect the two sides of the window frame 3 according to the principle that the upper hydraulic damping mechanism 18 plays a buffering role when being extruded in the embodiment 1, so that the overall protection effect on the window frame 3 is improved.

Example 3

Under the earthquake and strong vibration, although the upper hydraulic damping mechanism 18 and the lower hydraulic damping mechanism 19 can better buffer and protect the window frame 3, the window frame 3 still cannot be extruded and deformed under the serious earthquake and vibration, and when the window frame 3 is seriously damaged and deformed, the escape passage is blocked, and a larger potential safety hazard is caused to the escape route from the window, so the device is further improved.
