Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a shock-absorbing tie rod structure. Background Technology

[0002] Seismic damping rods are devices used to improve the seismic performance of buildings. They are designed to absorb and dissipate dynamic stress and energy experienced by the building structure during an earthquake. Installed on critical load-bearing components, seismic damping rods reduce the amplitude of structural vibrations through the elastic deformation of the material, thereby ensuring the safety and stability of the building. Seismic damping rods are made of high-strength metals or composite materials to ensure they can withstand seismic stresses and transfer energy.

[0003] In existing technologies, the damping performance of seismic damping rods is insufficient in practical applications. These rods exhibit limited adaptability to different earthquake frequencies and intensities, and the structural integrity of the material may deteriorate during use, leading to unstable damping effects. In complex seismic environments, these issues can prevent the rods from effectively coping with multi-directional impacts, affecting the overall seismic performance of the building.

[0004] Therefore, improving the damping performance of shock absorber tie rods has become a key technical problem that urgently needs to be solved in order to improve the energy dissipation efficiency of the tie rods and enhance their adaptability to various seismic environments. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a shock-absorbing tie rod structure, comprising:

[0006] A sleeve has a first opening at one end and a first connector at the other end away from the first opening. A first sealing ring is fitted inside the first opening of the sleeve, and a second sealing ring is fitted inside the sleeve. An oil cavity is formed between the first sealing ring and the second sealing ring.

[0007] A pull rod passes through the center of the first sealing ring and the second sealing ring, and can be relatively close to or far away from the first connector inside the sleeve. The other end of the pull rod away from the first connector has a second connector.

[0008] A piston is disposed between the first sealing ring and the second sealing ring and is fixedly sleeved on the pull rod. The piston divides the oil chamber into a first chamber and a second chamber.

[0009] The pull rod has a through hole that connects the first chamber and the second chamber. Both ends of the through hole have cover plates that can be positioned close to or away from the through hole. A compression assembly is located between the cover plates and the pull rod. When vibration increases, the liquid flowing through the through hole increases in speed, compressing the compression assembly. The cover plates then fit against the through hole, sealing the oil chamber. The first sealing ring, the second sealing ring, and the piston all have sealing rings between them and the sleeve.

[0010] In some embodiments of this utility model, the sleeve includes a first cylindrical body with a first opening and a second cylindrical body with a first connecting rod. The first cylindrical body and the second cylindrical body are screwed together, and the screwed connection also has a locking member passing through the first cylindrical body and the second cylindrical body.

[0011] In some embodiments of this utility model, the second sealing ring is disposed inside the first cylinder, and the other end of the first cylinder away from the first opening is the second opening. When the second cylinder is connected to the first cylinder, the second cylinder abuts against the second sealing ring.

[0012] In some embodiments of this utility model, both the first sealing ring and the second sealing ring have a stepped structure between themselves and the first cylinder, and both the first sealing ring and the second sealing ring are engaged with the first cylinder through the stepped structure.

[0013] In some embodiments of this utility model, the pull rod includes a first connecting rod and a second connecting rod, the first connecting rod passes through the first sealing ring and the piston, the second connecting rod passes through the second sealing ring, and the first connecting rod and the second connecting rod are fixedly connected inside the second chamber.

[0014] In some embodiments of this utility model, the through hole includes an oil port opened on the pull rods at both ends of the piston, an oil groove connected to the oil port, and a cover plate disposed inside the oil port, the cover plate being relatively close to or away from the oil groove.

[0015] In some embodiments of this utility model, the compression assembly includes a compression groove formed inside the pull rod, a compression member disposed in the compression groove, a guide rod with one end connected to the cover plate and the other end abutting against the compression member, the guide rod being relatively close to or away from the compression groove.

[0016] In some embodiments of this utility model, the cover plate is circular with an opening in the middle, and the oil port of the pull rod further includes a first connecting section and a central connecting section. The opening is fitted onto the central connecting section, and there are gaps between the cover plate and the first connecting section and the central connecting section.

[0017] In some embodiments of this utility model, the pull rod has a sealing ring between itself and the first sealing ring and the second sealing ring.

[0018] In some embodiments of this utility model, the end of the pull rod near the second connector also has a housing, the housing is sleeved on the outside of the sleeve, and there is a scale between the outside of the sleeve and the housing.

[0019] The beneficial effects of this invention are as follows: This invention utilizes a sleeve and a tie rod passing through it. Liquid flow is achieved through an oil cavity formed between a first and second sealing ring. A piston divides the oil cavity into two chambers. A through hole on the tie rod connects the two chambers. When vibration increases, the liquid flow rate accelerates, compressing the compression assembly under the cover plate, causing the cover plate to adhere to the through hole and achieve a seal. During an earthquake, this invention can automatically adjust the damping effect according to the liquid flow velocity, ensuring the oil cavity remains sealed under high-intensity vibrations, preventing unnecessary liquid loss, and allowing the shock-absorbing tie rod to be in a stiffened state, improving dissipation efficiency. This dynamic feedback mechanism significantly enhances the stability and seismic resistance of the structure, reduces the vibration amplitude of the building, and provides more efficient vibration damping protection.

[0031] like Figures 1 to 6 The shock-absorbing tie rod structure shown includes:

[0032] The sleeve 1 has a first opening 11a at one end and a first connecting member 2 at the end away from the first opening 11a. A first sealing ring 3 is fitted inside the sleeve 1 at the first opening 11a, and a second sealing ring 4 is fitted inside the sleeve 1. An oil cavity 6 is formed between the first sealing ring 3 and the second sealing ring 4. It should be noted that the connection between the first connecting rod and the sleeve 1 can be a threaded connection, a snap-fit ​​connection, welding, or other connectable structural forms. It should also be noted that the specific length of the sleeve 1 can be set according to actual needs.

[0033] The pull rod 7 passes through the center of the first sealing ring 3 and the second sealing ring 4, and can be relatively close to or away from the first connecting member 2 inside the sleeve 1. The other end of the pull rod 7 away from the first connecting member 2 has a second connecting member 71. It should be noted that the connection method between the second connecting member 71 and the pull rod 7 is the same as the connection method between the first connecting member 2 and the sleeve 1, and there can be many forms.

[0034] Piston 8 is positioned between the first sealing ring 3 and the second sealing ring 4 and is fixedly sleeved on the pull rod 7. Piston 8 divides the oil chamber 6 into a first chamber 61 and a second chamber 62. It should be noted that the sum of the volumes of the first chamber 61 and the second chamber 62 remains unchanged.

[0035] The pull rod 7 has a through hole 14, which connects the first chamber 61 and the second chamber 62. Both ends of the through hole 14 have cover plates 15, which can be positioned closer to or further away from the through hole 14. A compression assembly 16 is located between the cover plate 15 and the pull rod 7. When vibration increases, the liquid flowing through the through hole 14 increases in velocity, compressing the compression assembly 16. The cover plate 15 then fits against the through hole 14, sealing the oil chamber 6. The first sealing ring 3, the second sealing ring 4, and the piston 8 all have sealing rings 5 ​​between them and the sleeve 1. Figure 1 As shown, the first chamber 61 and the second chamber 62 are connected by a through hole 14, allowing the liquid in the oil chamber 6 to reciprocate. When vibration occurs, the liquid in the oil chamber 6 accelerates through the through hole 14, applying pressure to the cover plates 15 at both ends of the through hole 14. The compression assembly 16 compresses the liquid, causing the cover plates 15 to move towards the through hole 14, covering the through hole 14. This prevents the liquid in the first chamber 61 and the second chamber 62 from flowing, and also creates rigidity between the sleeve 1 and the tie rod 7, enabling the shock-absorbing tie rod to function and provide a pulling effect on the building, reducing damage caused by vibration. It should be noted that the number of sealing rings 5 ​​can be one or more depending on the actual use. It should also be noted that the shape of the sealing rings 5 ​​can be varied, including circular, lip-shaped, or different shapes depending on the groove.

[0036] This invention utilizes a sleeve 1 and a tie rod 7 passing through it. Liquid flow is achieved through an oil cavity 6 formed between a first sealing ring 3 and a second sealing ring 4. A piston 8 divides the oil cavity 6 into two chambers. A through hole 14 on the tie rod 7 connects the two chambers. When vibration increases, the liquid flow rate accelerates, compressing the compression assembly 16 under the cover plate 15, causing the cover plate 15 to adhere to the through hole 14 and achieve a seal. During an earthquake, this invention automatically adjusts the damping effect according to the liquid flow velocity, ensuring the oil cavity 6 remains sealed under high-intensity vibrations, preventing unnecessary liquid loss, and allowing the shock-absorbing tie rod to maintain a stiff state, thus improving dissipation efficiency. This dynamic feedback mechanism significantly enhances the structural stability and earthquake resistance, reducing the vibration amplitude of buildings and providing more efficient vibration protection.

[0037] A second sealing ring 4 is installed inside the sleeve 1. To ensure a tighter connection between the second sealing ring 4 and the sleeve 1, and to reduce the possibility of the shock-absorbing rod loosening during vibration or use, such as... Figure 2 , Figure 3 As shown, the sleeve 1 includes a first cylindrical body 11 with a first opening 11a and a second cylindrical body 12 with a first connecting rod. The first cylindrical body 11 and the second cylindrical body 12 are screwed together, and a locking member 17 passing through the first cylindrical body 11 and the second cylindrical body 12 is also provided at the screw connection. By setting the screw connection between the first cylindrical body 11 and the second cylindrical body 12 and the locking member 17, a stable combination of the sleeve 1 is achieved through a tight connection. The screw connection provides an adjustable connection method, making equipment installation and maintenance easier and more flexible. The locking member 17 further ensures the firmness of the connection, is not affected by external vibration, improves the overall strength and durability of the structure, and also provides higher seismic resistance, which can maintain the integrity of the cylindrical body connection in the event of an earthquake.

[0038] To improve the practicality of installing shock-absorbing tie rods, such as Figure 3 As shown, the second sealing ring 4 is disposed inside the first cylinder 11. The other end of the first cylinder 11 away from the first opening 11a is the second opening 12a. When the second cylinder 12 is connected to the first cylinder 11, the second cylinder 12 abuts against the second sealing ring 4. This invention places the second sealing ring 4 inside the first cylinder 11 and designs it to abut against the second cylinder 12 when connected, ensuring that the sealing ring remains in a fixed position during device operation. This effectively prevents liquid leakage and resists structural loosening caused by vibration. The fit between the second cylinder 12 and the second sealing ring 4 enhances the overall structural sealing and improves the system's damping efficiency in the face of seismic impacts.

[0039] Continue to refer to Figure 2 , Figure 3As shown, traditional shock-absorbing tie rods may experience sealing ring detachment or displacement under high stress and vibration environments, leading to sealing performance failure and poor shock absorption. Both the first sealing ring 3 and the second sealing ring 4 have stepped structures 13 between themselves and the first cylinder 11, and both the first sealing ring 3 and the second sealing ring 4 are engaged with the first cylinder 11 through these stepped structures. These stepped structures enhance the fixation and stability of the sealing rings. This structural design ensures that the sealing rings always remain in the predetermined position, reducing the risk of displacement due to vibration or other external forces, thereby effectively improving the sealing performance of the sleeve 1. Through the engaging design of the stepped structure 13, the sealing rings are less prone to loosening or detachment, further ensuring the system's damping effect and overall service life.

[0040] like Figures 1 to 3 As shown, the pull rod 7 includes a first connecting rod 72 and a second connecting rod 73. The first connecting rod 72 passes through the first sealing ring 3 and the piston 8, and the second connecting rod 73 passes through the second sealing ring 4. The first connecting rod 72 and the second connecting rod 73 are fixedly connected inside the second chamber 62. This utility model adopts a two-section structure, which solves the technical problem of installing the pull rod 7 on the one hand, and fixes the position of the piston 8 through the first connecting rod 72 and the second connecting rod 73 on the other hand. In the specific installation process, firstly, the first connecting rod 72 is passed through the first sealing ring 3 and the piston 8, then the second connecting rod 73 is connected and locked to the first connecting rod 72, then the second sealing ring 4 is fitted onto the second connecting rod 73, and finally the second cylinder 12 is installed on the first cylinder 11 to achieve sealing and installation of internal components.

[0041] like Figure 4 , Figure 5 As shown, traditional damping rods have limited ability to adjust fluid flow under different vibration conditions, which often results in damping performance that cannot meet the demands of dynamic vibration control. Especially during severe vibrations, the fluid cannot quickly adjust its flow velocity to respond to the sudden intensification of the earthquake. The through-hole 14 includes an oil port 14a opened on the tie rods 7 at both ends of the piston 8, an oil groove 14b connected to the oil port 14a, and a cover plate 15 disposed inside the oil port 14a. The cover plate 15 can be relatively close to or away from the oil groove 14b. By designing oil ports 14a on the tie rods 7 at both ends of the piston 8 and connecting them to the oil groove 14b, a flexible flow path solution is provided. The cover plate 15 allows for adjustment of the fluid flow relative to the oil groove 14b within the oil port 14a, allowing the fluid flow to be adjusted according to changes in flow velocity and pressure when vibration occurs, quickly adapting to different vibration intensities, enabling the fluid to effectively coordinate the damping effect under different conditions and achieve efficient energy dissipation.

[0042] like Figure 6As shown, to enable the cover plate 15 to respond more quickly during actual use and move closer to the through hole 14, the compression assembly 16 includes a compression groove 16a formed inside the tie rod 7, a compression element 16b disposed in the compression groove 16a, and a guide rod 16c with one end connected to the cover plate 15 and the other end abutting against the compression element 16b. The guide rod 16c can move relatively closer to or away from the compression groove 16a. By setting the compression element 16b in the compression groove 16a inside the tie rod 7 and connecting it to the cover plate 15, a dynamic adjustment system is formed. The design of the guide rod 16c allows it to move flexibly towards the compression groove 16a, adjusting closer to or away from it as the vibration increases or decreases. This ensures that under varying vibration conditions, the compression assembly 16 can adjust the pressure and damping effect in real time, ensuring that the shock-absorbing tie rod is always in the best working state. The flexibility of the guide rod 16c allows the compression system to quickly respond to earthquake changes and provide customized shock absorption effects.

[0043] Continue to refer to Figure 6 As shown, the cover plate 15 is circular with an opening 15a in the center. The oil port 14a of the pull rod 7 also includes a first connecting section 72a and a central connecting section 72b. The opening 15a is fitted onto the central connecting section 72b. There are gaps 72c between the cover plate 15 and both the first connecting section 72a and the central connecting section 72b. The circular cover plate 15 design provides a more reliable positioning effect by having a central opening 15a and fitting onto the central connecting section 72b. The gap 72c between the cover plate 15 and its connecting section provides space for fluid flow adjustment, which can quickly adapt to changes in vibration intensity and adjust the fluid pressure. This allows the fluid to flow at a controllable rate during an earthquake. Dynamic adjustment through the gap 72c ensures effective activation of the damping effect. The introduction of the opening 15a design not only ensures a stable liquid flow path but also avoids structural damage caused by excessive pressure.

[0044] like Figure 2 , Figure 3 As shown, the failure of the sealing structure is often caused by changes in the gaps between components during vibration, which in turn affects the vibration damping effect and long-term reliability of the device. Both the tie rod 7 and the first sealing ring 3 and the second sealing ring 4 have sealing rings 5. By introducing sealing rings 5 ​​between the tie rod 7 and the first sealing ring 3 and the second sealing ring 4, an additional leakage barrier is provided, which can effectively absorb stress changes caused by vibration, ensuring that the sealing connection remains tight and seamless. The sealing rings 5 ​​can not only withstand liquid pressure and prevent leakage, but also adapt to the requirements of structural changes and high-stress environments on connection stability, thus preventing the impact of fluid leakage on the vibration damping effect and extending the service life of the device.

[0045] Traditional vibration damping devices often lack intuitive interfaces for monitoring and adjustment, which can hinder precise adjustments to adapt to different vibration conditions. This can lead to reduced damping effectiveness during maintenance and operation due to a lack of accurate references. Figure 1 As shown, the end of the pull rod 7 near the second connector 71 also has a housing 9, which is fitted over the sleeve 1. A scale is provided between the sleeve 1 and the housing 9. By adding the housing 9 to the end of the pull rod 7, which fits over the sleeve 1 and has a scale between them, the shock-absorbing pull rod has an intuitive reference interface. The scale allows the user to monitor and adjust the position of the pull rod 7 in real time to meet specific shock absorption needs, providing clear positioning instructions for the operator and enabling quick and efficient adjustments to optimize shock absorption performance.
