Description

Technical Field

[0001] This utility model belongs to the field of seismic bracing technology, specifically relating to a seismic bracing with adjustable function. Background Technology

[0002] Seismic bracing is a device used to support and fix structures such as pipes and equipment. It is widely used in buildings, bridges and industrial facilities to improve their safety in earthquake or other vibration environments.

[0003] A search of Chinese utility model patents reveals a seismic bracing device (publication number: CN221278346U), comprising a base with a buffer structure on top. The buffer structure includes a sliding plate, a fixed block, a first spring, a moving block, a slider, a groove, connecting rods, a hinge seat, a top plate, gears, a rack, a second spring, and a limiting block. This seismic bracing device, through the buffer structure, allows the bracing to withstand downward force. When the bracing is subjected to downward force, the hinge seat moves downward, causing the two connecting rods to deform. The two connecting rods then cause the two moving blocks to gradually move away. The first spring contracts until the vibration disappears. The rebound force of the first spring causes the two moving blocks to gradually move closer, driving the two connecting rods to return the top plate to its original position. When the bracing is subjected to horizontal force, the sliding plate moves left or right via the gear until the vibration disappears. The second spring, through its deformation force, returns the sliding plate to its original position. This device can mitigate vertical and horizontal vibrations, preventing displacement and damage to electrical engineering facilities.

[0004] While the aforementioned patents can mitigate vertical and horizontal vibrations of the support structure through the combination of springs and sliding plates, in practical applications, the placement of equipment on the support cannot be flexibly adjusted, making it difficult to adapt to the installation needs of equipment of different sizes or shapes. This fixed structural design limits the applicability of seismic bracing, increases the difficulty of installation and adjustment, and also reduces the flexibility and efficiency of equipment layout. Therefore, developing a seismic bracing with adjustable functions that can flexibly adjust the placement of equipment according to actual needs, while also possessing excellent seismic performance, has become a pressing technical challenge in the field of seismic bracing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable seismic brace, comprising a base, an anti-seismic mechanism on the top of the base, an adjusting mechanism on the top of the anti-seismic mechanism, an adjusting plate, and two rectangular grooves on the outer wall of the top of the adjusting plate. A lead screw is mounted inside one of the rectangular grooves via bearings, and a moving block is threaded onto the outer wall of the lead screw. A guide rod is fixedly mounted inside the other rectangular groove, and a guide block is slidably connected to the outer wall of the guide rod. A limiting plate is fixedly connected between the moving block and the guide block. A rubber buffer plate is fixedly connected to one side of the limiting plate.

[0010] In a preferred embodiment, the anti-seismic mechanism includes a damping shock absorber and a disc spring fixedly connected to the bottom of the adjustment plate. The damping shock absorber is located at the four corners of the bottom of the adjustment plate, and the disc spring is located at the center of the bottom of the adjustment plate.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-5 This utility model provides a seismic bracing system with adjustable function, the structural design and operating principle of which are explained in the attached diagram. Figure 1 To be continued Figure 5 The following is a detailed description of the specific embodiments of this utility model, in conjunction with the accompanying drawings and specific component reference numerals.

[0024] like Figure 1 As shown, the overall structure of this utility model includes a base 1, an anti-seismic mechanism 2, and an adjustment mechanism 3. The base 1 serves as the basic support for the entire bracket, and its surface is reinforced to improve its load-bearing capacity. The base 1 is made of high-strength steel and has anti-slip pads at its bottom to ensure that it can firmly adhere to the ground or other load-bearing surfaces during installation. The anti-seismic mechanism 2 is located on top of the base 1. The core components of the anti-seismic mechanism 2 include a rubber base plate 21, a damping shock absorber 22, and a disc spring 23. The adjustment mechanism 3 is located on top of the anti-seismic mechanism 2. The adjustment mechanism 3 includes an adjustment plate 31, a lead screw 32, a moving block 33, a guide rod 34, a guide block 35, a limiting plate 36, a rubber buffer plate 37, a flip plate 38, and a telescopic airbag 312. These components work together to achieve range adjustment of the bracket and improve its anti-seismic performance.

[0025] The specific structure of seismic-resistant mechanism 2 is as follows: Figure 5 As shown, the rubber base plate 21 has a rectangular structure and is fixedly connected to the bottom of the damping shock absorber 22, and is tightly fitted to the base 1. The rubber base plate 21 is made of high-elasticity composite rubber with a hardness range of Shore A60 to A80 to ensure uniform deformation and absorption of vibration energy under stress. There are four damping shock absorbers 22, which are located at the four corners of the bottom of the adjusting plate 31 to absorb vertical vibration energy. The damping shock absorber 22 adopts a hydraulic damping structure inside, which dissipates vibration energy through the resistance generated by the fluid flow, thereby reducing the impact of earthquakes or external impacts on the support. The disc spring 23 adopts a multi-layered structure and is located at the center of the bottom of the adjusting plate 31 to further enhance the seismic resistance.

[0026] The specific structure of the regulating mechanism 3 is as follows: Figure 2As shown, the top outer wall of the adjusting plate 31 has two rectangular slots. A lead screw 32 is installed in one of the rectangular slots via a bearing. A knob for driving the lead screw 32 is fixedly connected to one end of the lead screw 32. A guide rod 34 is fixedly installed in the other rectangular slot. A moving block 33 is threadedly connected to the outer wall of the lead screw 32. The moving block 33 moves along the axial direction of the lead screw 32. A guide block 35 is slidably connected to the outer wall of the guide rod 34. The guide block 35 is fixedly connected to the moving block 33 to ensure that the linear movement of the moving block 33 is smooth and does not deviate. A limit plate 36 is fixedly connected between the moving block 33 and the guide block 35. A rubber buffer plate 37 is fixedly connected to one side of the limit plate 36. The rubber buffer plate 37 is made of natural rubber and is used to limit the range of movement and provide additional cushioning protection. There are two limit plates 36 and two rubber buffer plates 37, both rectangular in shape, located on both sides of the adjusting plate 31 to ensure the stability of the equipment when placed and further improve the seismic resistance of the anti-seismic bracket.

[0027] The front and rear sides of the adjusting plate 31 are hinged with flip plates 38. The outer side of the flip plates 38 is fixedly connected with a telescopic airbag 312. The top of the telescopic airbag 312 is fixedly installed with an air inlet pipe 313 and an air outlet pipe 315. The air inlet pipe 313 and the air outlet pipe 315 are respectively inserted with a first sealing plug 314 and a second sealing plug 316 to control the inflation and deflation of the telescopic airbag 312, thereby achieving the limiting effect and seismic effect of the front and rear of the anti-seismic bracket. The telescopic airbag 312 is used to further fix and dampen the equipment.

[0028] A fixing assembly is provided between the adjusting plate 31 and the flip plate 38. The fixing assembly includes fixing blocks 39 fixedly connected to the front and rear sides of the adjusting plate 31. A connecting screw 310 is provided through the inside of the fixing block 39. Both sides of the flip plate 38 are provided with connecting screw holes 311 that match the connecting screw 310. By screwing the connecting screw 310 into the connecting screw hole 311, the angle of the flip plate 38 is fixed, thereby meeting the usage requirements in different scenarios. There are two flip plates 38. The connection method between the connecting screw 310 and the connecting screw hole 311 is a threaded connection, ensuring that the flip plate 38 can be firmly fixed after adjustment. After the angle of the flip plate 38 is adjusted, it is convenient for the operator to move the equipment and objects on the anti-vibration support.

[0029] The synergistic mechanism between seismic resisting mechanism 2 and regulating mechanism 3 is as follows: Figure 1 and Figure 2 As shown, when external vibration is transmitted to the anti-vibration mechanism 2, the damping shock absorber 22 first absorbs and dissipates most of the vertical vibration energy. At the same time, the disc spring 23 disperses the remaining energy through elastic deformation, thereby reducing the impact on the adjustment mechanism 3. On this basis, the rubber buffer plate 37 and the telescopic airbag 312 in the adjustment mechanism 3 further provide buffer protection to avoid equipment damage caused by vibration.

[0030] The specific operation process of this utility model is as follows: First, the base 1 is fixedly installed on the ground or other bearing surface, ensuring that the base 1 is in close contact with the bearing surface. By removing the first sealing plug 314 and injecting gas into the air inlet pipe 313, the telescopic airbag 312 expands to fix the equipment in front and behind, while buffering the equipment, thereby increasing the height of the bracket. After adjusting the front and rear range, the angle of the flip plate 38 is fixed by screwing the connecting screw 310 into the connecting screw hole 311 on the flip plate 38. The knob is turned to drive the lead screw 32 to rotate, thereby moving the moving block 33 along the axial direction of the lead screw 32. The position of the limiting plate 36 is adjusted to adapt to equipment of different sizes. After the equipment is placed, the rubber buffer plate 37 provides additional buffer protection to ensure that the equipment remains stable in the vibration environment. When external vibration is transmitted to the bracket, the damping shock absorber 22 and the disc spring 23 in the anti-vibration mechanism 2 work together to absorb and dissipate vibration energy, reducing the impact on the equipment.

[0031] In summary, this utility model solves the problem of the inflexible adjustment of existing seismic bracing through innovative structural design, while significantly improving seismic performance and reliability. The specific implementation of this utility model fully discloses each step of the technical solution, ensuring that the technical solution can be clearly understood and implemented.
