The adjusting mechanism 300 further comprises a push plate 370, the push plate 370 is slidably mounted on the second slide channel 354, a part of the width of the push plate 370 mounted in the second slide channel 354 is greater than that of the first slide channel 353, and the push plate 370 is slidably mounted on the rotating plate 310 along the tilting direction of the rotating plate 310 and is hinged to the rotating plate 310 in the first axial direction; when the rotating plate 310 drives the sliding plate 340 to move upwards until the sliding block 342 is separated from the first slide way 353, the push plate 370 moves upwards along with the rotating plate 310 to abut against a step surface between the first slide way 353 and the second slide way 354, and specifically, the sliding block 342 can be separated from the first slide way 353 and the push plate 370 can be synchronously abutted against the step surface by making the distance between the sliding block 342 and the upper end of the sliding plate structure 350 and the distance between the push plate 370 and the step surfaces between the first slide way 353 and the second slide way 354 equal in an initial state; when the rear rotating plate 310 continues to move upwards, the push plate 370 drives the sliding plate structure 350 to move upwards;

In other embodiments of the present invention, the limiting member 330 is slidably mounted on the bracket 200 and the limiting member 330 can be controlled by an electric control element, specifically, when a difference between an acting force of wind on the roof plate 100 and an acting force of rain and snow on the roof plate 100 is greater than a first preset value, or when a difference between an acting force of rain and snow on the roof plate 100 and an acting force of wind on the roof plate 100 is greater than a second preset value, the roof plate 100 will generate a certain displacement in a vertical direction under the action of wind or rain and snow gravity, and the sensor senses a displacement of the roof plate 100 under the action of wind or rain and snow gravity, and triggers the limiting member 330 to slide to abut against the hinge base 400, so as to limit the hinge base 400 from moving up and down.
In this embodiment, the side of the sliding plate structure 350 facing the hinge base 400 is provided with a friction portion 356 and a rolling portion 357, wherein the friction portion 356 is a rough surface for increasing the resistance of the outer end of the limiting member 330 to the relative movement with the sliding plate structure 350; the rolling portion 357 is provided with a plurality of rollers rotating around the first axial direction for reducing the resistance of the outer end of the limiting member 330 to the relative movement with the sliding plate structure 350. The friction portion 356 is located below the stopper groove 355, and the friction force when the outer end of the stopper 330 abuts against the friction portion 356 is larger than the friction force when the outer end abuts against the rolling portion 357. After the sliding plate structure 350 moves upwards to separate the limiting member 330 from the limiting groove 355, the outer end of the limiting member 330 abuts against the friction portion 356, so as to increase the friction force of the sliding plate structure 350 moving upwards, further slow down the speed of the outer end of the rotating plate 310 rotating upwards, and prevent the roof plate 100 from being lifted up quickly; after the sliding plate structure 350 moves downward to separate the limiting member 330 from the limiting groove 355, the outer end of the limiting member 330 abuts against the rolling part 357, so as to reduce the downward movement friction of the sliding plate structure 350, further increase the downward movement speed of the outer end of the rotating plate 310, and accelerate the snow on the roof plate 100 to slide down.
In this embodiment, the bracket 200 is provided with a first mounting hole 210, and the sliding column 360 is slidably mounted in the first mounting hole 210 up and down; a stop block 220 is arranged on the side wall of the first mounting hole 210, the stop block 220 extends into the first mounting hole 210 under the action of a fourth spring (not shown in the figure), and an avoiding groove 362 matched with the stop block 220 is arranged on the side surface of the sliding column 360; the stop 220, when engaged with the escape slot 362, blocks the sliding post 360 from moving further upward and allows the sliding post 360 to move downward; in the initial state, the stopper 220 is retracted into the sidewall of the first mounting hole 210 by the pressing of the sliding column 360, and the elastic stopper 220 is extended to engage with the escape groove 362 when the sliding column 360 moves upward to the predetermined position.
In this embodiment, the upper end surface of the stopper 220 is an inclined surface, and the lower end surface of the stopper 220 is a horizontal surface; the lower end face of the avoiding groove 362 is a horizontal plane, when the stopper 220 is matched with the avoiding groove 362, the lower end face of the stopper 220 is abutted against the lower end face of the avoiding groove 362 to prevent the sliding column 360 from moving upwards, and when the sliding column 360 moves downwards, the stopper 220 is extruded along the upper end face of the stopper 220 to retract.
In the present embodiment, each sliding plate structure 350 is composed of two sliding plates 351, the two sliding plates 351 are spaced from each other, and a first slideway 353 and a second slideway 354 are defined between the two sliding plates 351.
In an initial state of the earthquake-resistant and shock-absorbing structure for building roofs of the present invention, the hinge side of the two roof plates 100 is higher than the other side of the roof plates 100 such that the inner ends of the pivoting plates 310 are higher than the outer ends of the pivoting plates 310, and the sliding columns 360 support the second springs 361 to allow the sliders 342 at both ends of the second rotating shaft 341 to be positioned in the first slide 353.
When the difference between the force of wind on the roof plate 100 and the force of rain and snow on the roof plate 100 is smaller than the first preset value, and the difference between the force of rain and snow on the roof plate 100 and the force of wind on the roof plate 100 is smaller than the second preset value, the first slide 353 limits the rotation of the sliding plate 340, and further limits the rotation of the rotating plate 310 around the hinge shaft 311 and the rotation of the roof plate 100 around the first rotating shaft 110, and the roof plate 100 vibrates up and down under the action of the wind force and the second spring 361 and the fifth spring 410, or vibrates up and down under the action of the gravity of rain and snow and the second spring 361 and the fifth spring 410, and the influence of the force of the roof plate 100 on the bracket 200 is reduced through the second spring 361 and the fifth spring 410.
In windy weather, when the difference between the acting force of wind force on the roof plate 100 and the acting force of rain and snow on the roof plate 100 is greater than the first preset value, the roof plate 100 drives the rotating plate 310 and the sliding plate 340 to move upwards under the action of wind force until the sliding block 342 is separated from the first slideway 353, the push plate 370 moves upwards along with the rotating plate 310 to abut against the step surface between the first slideway 353 and the second slideway 354, and the push plate 370 drives the sliding plate structure 350 to move upwards when the rear rotating plate 310 continues to move upwards. When the sliding plate structure 350 moves upward, the outer end of the limiting member 330 is disengaged from the limiting groove 355 and then abuts against the friction portion 356, and meanwhile, the limiting member 330 is pushed by the side surface of the sliding plate structure 350 to move downward in the direction close to the hinge base 400, so that the clamping plate 332 is clamped with the clamping teeth, and the hinge base 400 is further limited from moving up and down. The rear roof panel 100 rotates upward around the first rotating shaft 110 under the action of wind power, and drives the rotating plate 310 to rotate upward around the hinge shaft 311 and the sliding plate 340 to rotate upward around the second rotating shaft 341, meanwhile, the rotating plate 310 drives the sliding plate structure 350 to move upward through the push plate 370, and the sliding plate 340 drives the sliding column 360 to move upward through the second rotating shaft 341; in the process of upward movement of the sliding plate structure 350, the outer end of the limiting member 330 abuts against the friction portion 356, so that the resistance of the upward movement of the sliding plate structure 350 is increased, the upward rotation speed of the outer end of the rotating plate 310 is slowed down, and the roof 100 is prevented from being lifted up quickly. When the sliding column 360 moves upwards to a preset position, the stopper 220 is matched with the avoiding groove 362 under the action of the fourth spring to prevent the sliding column 360 from further moving upwards, and further prevent the roof deck 100 from further rotating upwards through the sliding plate 340 and the rotating plate 310, so that the maximum upward rotating angle of the roof deck 100 is limited, and the roof deck 100 is prevented from being reversely lifted over a horizontal position.
When the difference between the acting force of rain and snow on the roof deck 100 and the acting force of wind on the roof deck 100 is greater than the second preset value, the roof deck 100 drives the rotating plate 310 and the sliding plate 340 to move downwards under the action of the gravity of rain and snow or hail to be separated from the first slideway 353, the rotating plate 310 moves downwards to be abutted against the sliding plate structure 350, and then the rotating plate 310 pushes the sliding plate structure 350 to move downwards when continuing to move downwards along with the roof deck 100. When the sliding plate structure 350 moves downward, the outer end of the limiting member 330 is disengaged from the limiting groove 355 and then abuts against the rolling portion 357, and meanwhile, the limiting member 330 is pushed by the side surface of the sliding plate structure 350 to move downward toward the hinge base 400, so that the clamping plate 332 is clamped with the clamping teeth, and the hinge base 400 is further limited from moving up and down. The back roof plate 100 rotates downwards around the first rotating shaft 110 under the action of gravity of rain, snow or hail, and drives the rotating plate 310 to rotate downwards around the hinge shaft 311 and the sliding plate 340 to rotate downwards around the second rotating shaft 341, meanwhile, the rotating plate 310 pushes the sliding plate structure 350 to move downwards, in the process of moving downwards of the sliding plate structure 350, because the outer end of the limiting part 330 is in rolling contact with the roller of the rolling part 357, the resistance of the sliding plate structure 350 to move downwards is reduced, and further the speed of the outer end of the rotating plate 310 to rotate downwards is accelerated, so that the roof plate 100 rotates downwards quickly, and the rain, snow or hail on the roof plate 100 slides down.
After the windstorm stops or the rain, snow or hail on the roof panel 100 slips, the sliding column 360 returns to the initial position under the action of the second spring 361, the sliding plate structure 350 returns to the initial position under the action of the first spring 352, the limiting member 330 moves away from the hinge base 400 under the action of the third spring 331 so that the clamping plate 332 is disengaged from the clamping teeth, and the hinge base 400 returns to the initial position under the action of the fifth spring 410.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
