[0002] An earthquake safety controller is a building vibration damping device primarily used to enhance the safety and resilience of buildings under strong earthquakes. Its core feature is its ability to dissipate seismic energy and reduce structural damage during an earthquake, thereby lowering maintenance costs and improving the building's ability to be quickly restored to usable condition.

[0003] However, existing seismic isolation bearings for buildings often lack the function of automatic reset and may retain permanent deformation, often requiring manual replacement or repair, which causes inconvenience during use. Therefore, there is an urgent need for a self-resetting seismic safety controller to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a self-resetting earthquake safety controller to solve the problem mentioned in the background art that existing earthquake building damping bearings often do not have the function of automatic reset, may have permanent deformation, and often need to be replaced or repaired manually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-resetting earthquake safety controller, comprising a base, an arc-shaped curved panel, a slider, a top plate, and a buffer structure. The top of the base is fixedly connected to the arc-shaped curved panel, the top of the arc-shaped curved panel is slidably connected to the slider, and the top of the slider is fixedly connected to the top plate. The buffer structure includes a first fixed seat, a second fixed seat, a viscous damper, and a first support rod. Sixteen first and second fixed seats are provided. The bottom of each first fixed seat is fixedly connected to the top of the base. The top of the first seat is fixedly connected to the first ball joint. The top of the second fixed seat is fixedly connected to the bottom of the top plate. The bottom of the second fixed seat is fixedly connected to the second ball joint. Eight viscous dampers are provided. The cylinder of the viscous damper is fixedly connected to the ball head pin of the first ball joint. The piston rod of the viscous damper is fixedly connected to the ball head pin of the second ball joint. Eight support rods are provided. The support rods are fixedly connected to the ball head pin of the first ball joint. The support rods are slidably connected to the second support rod. The second support rod is fixedly connected to the ball head pin of the second ball joint.

[0006] Preferably, the top of the base has a groove, the inner wall of the groove is fixedly connected to the bottom of the arc-shaped curved panel, and the side of the groove has a slot.

[0007] Preferably, the top of the curved panel is a stainless steel wear-resistant layer, and the middle of the curved panel is a cast steel substrate with reinforcing ribs.

[0008] Preferably, the bottom of the slider is in contact with the surface of the curved panel, and the slider is made of cast steel.

[0009] Preferably, the outer wall of the slider has eight grooves, the grooves are rotatably connected to a rotating shaft, a roller is fixedly connected to the middle of the outer wall of the rotating shaft, and the outer wall of the roller is engaged with a slot.

[0011] Preferably, a memory spring is fitted inside the first support rod, with one end of the memory spring abutting against the inner wall of the first support rod and the other end of the memory spring abutting against the second support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This self-resetting earthquake safety controller is equipped with a base, an arc-shaped curved panel, and a slider. When an earthquake occurs, the foundation causes the base to shake. When the base shakes, the vibration is absorbed by a viscous damper. At this time, the slider slides along the arc-shaped curved panel, consuming earthquake energy through friction, thus achieving a damping effect. The slider's ultimate displacement is constrained by a groove. When the bottom outer wall of the slider contacts the inner wall of the base, it can be engaged in a slot by a roller. The roller causes the outer wall of the slider to slide along the inner wall of the groove, preventing the outer wall of the slider from impacting the inner wall of the base. The base, arc-shaped curved panel, and slider not only ensure vertical load-bearing stability but also ensure that earthquake displacement unfolds in a preset direction. Furthermore, the roller and slot rigidly limit the displacement, preventing overtravel that could cause the slider to overturn.

[0014] 2. This self-resetting earthquake safety controller is equipped with a buffer structure, with eight viscous dampers evenly distributed. Support rod one and support rod two are located between two viscous dampers. The eight viscous dampers can absorb vibrations in any direction. When the vibration stops, the slider and top plate can be reset by the memory spring. The buffer structure can not only absorb the vibrations generated by the earthquake, but also automatically reset the slider and top plate, making it more convenient and faster to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a self-resetting earthquake safety controller, comprising a base 1, an arc-shaped curved panel 2, a slider 3, a top plate 4, and a buffer structure 5. The top of the base 1 is fixedly connected to the arc-shaped curved panel 2, the top of the arc-shaped curved panel 2 is slidably connected to the slider 3, and the top of the slider 3 is fixedly connected to the top plate 4. The buffer structure 5 includes a first fixed seat 51, a second fixed seat 52, a viscous damper 55, and a first support rod 56. Sixteen first fixed seats 51 and sixteen second fixed seats 52 are provided. The bottom of each first fixed seat 51 is fixedly connected to the top of the base 1, and the top of the first fixed seat 51 is fixedly connected to a first ball joint 53. The top of the second fixed seat 52 is fixedly connected to the bottom of the top plate 4, and the bottom of the second fixed seat 52 is fixedly connected to a second ball joint 54. The viscous damper 55 is provided with... The system has eight viscous dampers 55, whose cylinders are fixedly connected to the ball joint pins of ball joint 53. The piston rods of the viscous dampers 55 are fixedly connected to the ball joint pins of ball joint 54. There are eight support rods 56, which are fixedly connected to the ball joint pins of ball joint 53. The support rods 56 are slidably connected to support rods 57, which are fixedly connected to the ball joint pins of ball joint 54. The base 1, the curved panel 2, and the slider 3 not only ensure the stability of the vertical bearing capacity, but also ensure that the seismic displacement unfolds in the preset direction. The rollers 33 and the slots 12 rigidly limit the displacement to prevent overtravel and slider overturning. The buffer structure 5 not only absorbs the vibration generated by the earthquake, but also automatically resets the slider 3 and the top plate 4.

[0023] Furthermore, a groove 11 is provided on the top of the base 1. The inner wall of the groove 11 is fixedly connected to the bottom of the curved panel 2. A slot 12 is provided on the side of the groove 11. The base causes the base 1 to shake. When the base 1 shakes, the slider 3 will slide along the curved panel 2. The groove 11 constrains the limit displacement of the slider 3.

[0024] Furthermore, the top of the curved panel 2 is a stainless steel wear-resistant layer, the middle of the curved panel 2 is a cast steel base with reinforcing ribs, and the bottom of the slider 3 is attached to the surface of the curved panel 2. The slider 3 is a cast steel body. The curved panel 2 and the slider 3 can not only ensure the stability of the vertical bearing capacity, but also ensure that the seismic displacement unfolds in the preset direction. The sliding friction between the curved panel 2 and the slider 3 consumes the seismic energy and plays a damping role.

[0025] Furthermore, the outer wall of the slider 3 is provided with eight grooves 31. The grooves 31 are rotatably connected to the rotating shaft 32. The outer wall of the rotating shaft 32 is fixedly connected to the roller 33. The outer wall of the roller 33 is engaged with the slot 12. When the bottom outer wall of the slider 3 contacts the inner wall of the base 1, the roller 33 can be engaged in the slot 12. The outer wall of the slider 3 slides along the inner wall of the groove 11 through the roller 33.

[0026] Furthermore, sliding grooves are provided on both the front and rear sides of support rod 56, and sliding rods are fixedly connected to both the front and rear sides of support rod 57. The sliding rods slide up and down in the sliding grooves, and the sliding rods play a limiting role. The sliding rods prevent support rod 57 from detaching from support rod 56, and make support rod 56 slide more smoothly, thus improving stability during movement.

[0027] Furthermore, a memory spring 58 is fitted inside the support rod 56. One end of the memory spring 58 abuts against the inner wall of the support rod 56, and the other end of the memory spring 58 abuts against the support rod 57. When the vibration stops, the slider 3 and the top plate 4 can be reset through the memory spring 58.

[0028] Working Principle: During use, when an earthquake occurs, the foundation causes the base 1 to shake. As the base 1 shakes, the vibration is absorbed by the viscous damper 55. At this time, the slider 3 slides along the curved panel 2, consuming seismic energy through friction, thus achieving a damping effect. The groove 11 constrains the extreme displacement of the slider 3. When the bottom outer wall of the slider 3 contacts the inner wall of the base 1, the roller 33 can engage in the slot 12. The roller 33 causes the outer wall of the slider 3 to slide along the inner wall of the groove 11, preventing the outer wall of the slider 3 from impacting the inner wall of the base 1. The base 1, the curved panel 2, and the slider 3... It can not only ensure the stability of vertical bearing capacity, but also ensure that the seismic displacement unfolds in the preset direction. The displacement is rigidly limited by the roller 33 and the slot 12 to prevent overtravel and slide overturning. Eight viscous dampers 55 are evenly distributed, and support rod 1 56 and support rod 2 57 are located between two viscous dampers 55. The eight viscous dampers 55 can absorb vibrations in any direction. When the vibration stops, the slide 3 and the top plate 4 can be reset by the memory spring 58. The buffer structure 5 can not only absorb the vibration generated by the earthquake, but also automatically reset the slide 3 and the top plate 4, making it more convenient and quick to use.
