Under earthquake, stronger vibrations, although last hydraulic damping mechanism 18 and lower hydraulic damping mechanism 19 can carry out better buffering and protection to window frame 3, under more serious earthquake, vibrations, window frame 3 has still avoided still not being extruded and deformed, is destroyed, warp by serious when window frame 3, can cause the passageway of fleing to block up, causes great potential safety hazard for the route of fleing from the window, consequently has carried out further improvement to this device.
As shown in fig. 7, an upper through hole 20 is formed in the lower half portion of the upper hydraulic damping mechanism 18, a lower through hole 21 is formed in the upper half portion of the lower hydraulic damping mechanism 19, a connecting pipe 22 is arranged between the upper through hole and the lower through hole, a first check valve 23 is arranged on the connecting pipe 22, and a pressurizing mechanism 25 is communicated with the bottom center of the lower hydraulic damping mechanism 19 through a pipeline; the pressurizing mechanism 25 is a manual hydraulic pump which is connected with the center of the bottom of the lower hydraulic damping mechanism 19 through a quick connector through a pipeline; after the earthquake and the larger vibration are finished, the window frame 3 is extruded and deformed, and at the moment, the piston rods 1804 on the upper hydraulic damping mechanism 18 and the lower hydraulic damping mechanism 19 drive the piston bodies to move downwards to the lower part of the oil cylinder body 1801, so that the spring 1805 is in a compressed state.
When needing to flee from window frame 3 that is extruded and deformed, twist the knob on hydraulic damper 18 and the lower hydraulic damper 19, anticlockwise rotation knob makes it rotate 90, choke valve 24 is in the closed position, make upper portion in the hydraulic damper 18, the lower part is not linked together, upper portion in the hydraulic damper 19, the lower part is not linked together, the hand lever through manual hydraulic pump pushes repeatedly the manual hydraulic pump this moment, pour into the oil body into in the hydro-cylinder body 1801 of hydraulic damper 19 bottom down through the pipeline, through pouring into the oil body that has pressure step by step, make the inside piston rod 1804 upward movement of lower hydraulic damper 19, can play a role at least this moment: on one hand, the lower hydraulic damping mechanism 19 can be enabled to extrude the lower deformed window frame 3 and the bottom concrete wall 3 through the top plate 1807 and the oil cylinder body 1801, the gap between the lower deformed window frame 3 and the bottom concrete wall 3 is increased, and at the moment, the spring 1805 is in a stretched state; on the other hand, the piston rod 1804 in the lower hydraulic damping mechanism 19 moves upwards to press the oil body above the piston body at the end of the piston rod 1804, at this time, because the throttle valve 24 is in the closed position, the oil body above the piston body at the end of the piston rod 1804 is pressed and opens the first check valve 23, enters the oil cylinder body 1801 below the upper hydraulic damping mechanism 18, because the throttle valve 24 on the upper hydraulic damping mechanism 18 is in the closed position, the oil body entering the oil cylinder body 1801 below the upper hydraulic damping mechanism 18 presses the piston rod 1804 of the upper hydraulic damping mechanism 18, further, the upper hydraulic damping mechanism 18 presses the window frame 3 and the top concrete wall body deformed above through the top plate 1807 and the oil cylinder body 1801, the gap between the window frame 3 and the top concrete wall body 3 deformed above is increased, and the spring 1805 is in the stretched state at this time; thirdly, because the upper part of the upper damping hydraulic mechanism 18 is respectively communicated with the left hydraulic damping mechanism 26 and the right hydraulic damping mechanism 27 through the pipeline and the second check valve 28, when the oil body in the cylinder body 1801 below the upper hydraulic damping mechanism 18 presses the piston rod 1804 of the upper hydraulic damping mechanism 18 to move upwards, the oil body above the piston body at the end part of the piston rod 1804 is pressed and opens the second check valve 28, the pressed oil body enters the right cylinder body 1801 of the left hydraulic damping mechanism 26 and the left cylinder body 1801 of the right hydraulic damping mechanism 27 through the pipeline, the oil body entering the right cylinder body 1801 of the left hydraulic damping mechanism 26 makes the left hydraulic damping mechanism 26 press the left deformed window frame 3 and the left side concrete wall 1 through the top plate 1807 and the cylinder body 1801, so as to increase the gap between the left deformed window frame 3 and the left side concrete wall 1, the spring 1805 is now in tension; the oil body entering the right oil cylinder body 1801 of the right hydraulic damping mechanism 27 enables the right hydraulic damping mechanism 27 to extrude the right deformed window frame 3 and the right side concrete wall 1 through the top plate 1807 and the oil cylinder body 1801, so as to increase the gap between the right deformed window frame 3 and the left side concrete wall 1, and at this time, the spring 1805 is in a stretched state; to increase the amount of oil entering the upper hydraulic damping mechanism 18 from the lower hydraulic damping mechanism 19, the knob may be rotated as needed to rotate it 90 degrees, with the throttle valve 24 in the throttle position.
After the gap between the lower deformed window frame 3 and the bottom concrete wall 3, the gap between the upper deformed window frame 3 and the top concrete wall 3, the gap between the left deformed window frame 3 and the left side concrete wall 1, and the gap between the right deformed window frame 3 and the left side concrete wall 1 are increased by the above operations, since the upper hydraulic damper mechanism 18, the lower hydraulic damper mechanism 19, the left hydraulic damper mechanism 26, and the right hydraulic damper mechanism 27 are all provided with the relief valves, all the relief valves are opened, the oil bodies in the upper hydraulic damper mechanism 18, the lower hydraulic damper mechanism 19, the left hydraulic damper mechanism 26, and the right hydraulic damper mechanism 27 are released, the pressure disappears, and the corresponding springs 1805 in the upper hydraulic damper mechanism 18, the lower hydraulic damper mechanism 19, the left hydraulic damper mechanism 26, and the right hydraulic damper mechanism 27 recover elastic deformation, the corresponding top plate 1807 on the upper hydraulic damping mechanism 18, the lower hydraulic damping mechanism 19, the left hydraulic damping mechanism 26 and the right hydraulic damping mechanism 27 forms a gap with the window frame 3, so that the deformed window frame 3 can be conveniently taken down, an escape channel is cleared, and the escape probability is increased.
