Description

Technical Field

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

[0002] A vibration damping tenon is a structural component primarily used in mechanical systems, building construction, and bridges to reduce the transmission of vibration and noise. Its main function is to reduce the impact of external vibrations on the structure through elastic deformation, energy absorption, and damping effects, effectively isolating vibration sources and protecting connected structural components.

[0003] In practical applications, with technological advancements, the increasing demands for damping performance in bridges have led to a need for further optimization of vibration reduction performance. In many applications, such as seismic-resistant bridge structures and vehicle damping systems, the damping effect directly impacts the stability and safety of the structure. Existing damping materials and structural designs in vibration damping devices are sometimes insufficient to fully absorb high-frequency and high-amplitude vibrations, resulting in unsatisfactory damping effects and potentially causing structural fatigue and damage.

[0004] To address the aforementioned technical issues, this application proposes an innovative damping tenon structure designed to enhance its damping effect, achieve more efficient energy absorption and damping, thereby significantly improving damping performance. Utility Model Content

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

[0006] The pre-embedded mechanism has two identical structures, each including a mounting plate connected to the outside, a sleeve assembly fixedly connected to the mounting plate, and a pressure plate fixed at the opening of the sleeve assembly, the pressure plate having a through hole;

[0007] A shock-absorbing mechanism, wherein both ends of the shock-absorbing mechanism pass through the through hole and extend into the sleeve assembly, and the ends of the shock-absorbing mechanism are connected to the center bolt of the mounting plate;

[0008] The shock-absorbing tenon has a variable diameter structure, with the largest diameter located inside the sleeve near the pressure plate.

[0009] In some embodiments of this utility model, the sleeve assembly further includes a limiting member fixedly connected to the mounting plate, the limiting member having a limiting hole, the end of the shock-absorbing mechanism extending into the limiting hole, and a limiting space between the end of the shock-absorbing mechanism and the inner diameter of the limiting hole.

[0010] In some embodiments of this utility model, the sleeve assembly also has a guide ring near the pressure plate. The guide ring is sleeved outside the shock-absorbing mechanism. At the position where the shock-absorbing mechanism is opposite to the guide ring, the diameter of the shock-absorbing mechanism is the largest.

[0011] In some embodiments of this utility model, the guide ring facing the shock absorption mechanism has a convex arc structure, and the convex arc structure is made of a wear-resistant material.

[0012] In some embodiments of this utility model, the shock absorption mechanism is a two-section structure with the same shape, both being shock absorption tenons, and a flange is fixedly connected between the two shock absorption tenons.

[0013] In some embodiments of this utility model, there are two flanges, both of which are fixedly connected to the shock-absorbing tenon, and a wear-resistant pad is provided between the two flanges.

[0014] In some embodiments of this utility model, the flange also has a receiving groove inside, and the diameter of the end of the shock-absorbing tenon extending into the receiving groove is larger than the opening of the receiving groove.

[0015] In some embodiments of this utility model, the receiving groove also has an elastic element, which covers the outer periphery of the shock-absorbing tenon.

[0016] In some embodiments of this utility model, the elastic element is EPDM, and its surface has a concave-convex structure.

[0017] In some embodiments of this utility model, the outer periphery of the sleeve assembly is further provided with reinforcing ribs at the connection between the sleeve assembly and the mounting plate.

[0018] The beneficial effects of this utility model are as follows: By combining the pre-embedded mechanism and the damping mechanism, this utility model achieves a superior damping effect. The double mounting plates of the pre-embedded mechanism, together with the fixedly connected sleeve assembly and the pressure plate with through holes, allow the end of the damping mechanism to effectively pass through the through holes and stably extend into the sleeve assembly, ensuring a firm connection between the damping mechanism and the mounting plate, thereby improving the stability of the overall structure. By maximizing the diameter of the tenon within the sleeve, especially near the pressure plate, the efficiency of damping is significantly increased, effectively concentrating and processing vibration energy. The special geometry of the internal structure optimizes energy dissipation, achieving more efficient vibration absorption and attenuation, improving the durability and reliability of the damping system, and making it more suitable for the high-standard application requirements of modern complex engineering environments.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 5 The shock-absorbing tenon structure shown includes:

[0030] The pre-embedded mechanism 1 has two identical structures, each including an externally connected mounting plate 11, a sleeve assembly 12 fixedly connected to the mounting plate 11, and a pressure plate 13 fixed at the opening of the sleeve assembly 12. The pressure plate 13 has a through hole 13a.

[0031] The shock absorption mechanism 2 has two ends that pass through the through hole 13a and extend into the sleeve assembly 12. The ends of the shock absorption mechanism 2 are connected to the center bolt 16 of the mounting plate 11.

[0032] Among them, the shock-absorbing tenon has a variable diameter structure, with the largest diameter located inside the sleeve near the pressure plate 13.

[0033] During the installation process, the pre-embedded mechanism 1 and the shock-absorbing mechanism 2 are first installed together, then the shock-absorbing tenon structure is placed in the installation position, the mounting plate 11 is fixedly connected, and then concrete is poured around the pre-embedded mechanism 1 to complete the installation.

[0034] To ensure that the damping mechanism 2 can return to its initial position after displacement due to vibration, such as Figure 3 As shown, the sleeve assembly 12 also includes a limiting member 14 fixedly connected to the mounting plate 11. The limiting member 14 has a limiting hole 14a, into which the end of the damping mechanism 2 extends. A limiting space 14b exists between the end of the damping mechanism 2 and the inner diameter of the limiting hole 14a. Traditional damping structures often face the problem of twisting or displacement of the vibration mechanism during long-term use, which affects the damping effect and may lead to structural damage. The limiting member 14, through its limiting hole 14a design, works in conjunction with the sleeve assembly 12 to precisely coordinate the end positioning of the damping mechanism 2. Under strong vibration conditions, the damping mechanism 2 can maintain its correct position in the sleeve assembly 12, reducing performance degradation that may be caused by displacement. The limiting space 14b within the limiting hole 14a supports a certain range of freedom of movement for the end of the damping mechanism 2 and avoids stress concentration problems that may result from complete fixation. This structure enhances the flexibility and stability of the damping system, improving the continuity and durability of damping performance.

[0035] like Figure 2 , Figure 3As shown, the sleeve assembly 12 also has a guide ring 15 near the pressure plate 13. The guide ring 15 is sleeved on the outside of the damping mechanism 2, and the diameter of the damping mechanism 2 is at its maximum at the position opposite to the guide ring 15. The guide ring 15 ensures the precise guidance and positioning of the damping mechanism 2. By sleeved on the outside of the damping mechanism 2, the structure of the guide ring 15 can constrain the movement of the damping mechanism 2, preventing it from deviating or moving irregularly during vibration. The diameter of the damping mechanism 2 at the position opposite to the guide ring 15 reaches its maximum, ensuring that the guide ring 15 can stably support the damping mechanism 2 and provide additional support and positioning when subjected to vibration impact.

[0036] Continue to refer to Figure 3 As shown, the guide ring 15 has a convex arc structure facing the damping mechanism 2, and this convex arc structure is made of wear-resistant material. The convex arc structure optimizes the contact surface, resulting in a more uniform distribution of contact stress between the guide ring 15 and the damping mechanism 2. This geometry not only provides a smoother guiding effect but also effectively reduces severe friction under dynamic loads, thereby lowering the frequency of wear. The use of a wear-resistant material for the arc structure further enhances its durability under repeated vibration and impact, ensuring the system maintains efficient operation even in high-load working environments. The convex arc structure of the guide ring 15 also improves the wear condition of the contact components.

[0037] like Figure 2 As shown, traditional single-stage damping structures may not provide sufficient flexibility and support in certain applications. To improve damping performance and increase design flexibility, this design introduces a two-stage structure. The damping mechanism 2 consists of two identical sections, each composed of damping tenons 21, with a flange 22 fixedly connected between them. By using two independent damping tenons 21, the system can provide a more adaptive response under different vibration conditions. The two sections can absorb vibrations of different frequencies and intensities, thus achieving a broader spectrum of damping effect. The fixed connection of the flange 22 not only enhances the overall stability of the structure but also allows for fine-tuning of the damping system's characteristics by adjusting the position and shape of the flange 22, enabling it to better cope with specific load conditions.

[0038] Traditional flange connection structures may face wear and loosening issues during prolonged use, affecting the overall stability and efficiency of the structure. For example... Figure 2 , Figure 3As shown, there are two flanges 22, both of which are fixedly connected to the damping tenon 21. A wear-resistant gasket 23 is also provided between the two flanges 22. By using two flanges 22, each flange 22 is independently connected to the damping tenon 21, which not only increases the strength of the connection but also effectively disperses stress concentration when bearing vibration loads. The wear-resistant gasket 23 between the two flanges 22 plays a buffering and separating role, further reducing friction and wear between the flanges. Because the material of the wear-resistant gasket 23 has good elasticity and wear resistance, it can withstand the wear load caused by repeated vibrations. Compared with the traditional single flange connection design, the double flange 22 connection not only improves the structural rigidity but also enhances the stability of the damping system in long-term use. The wear-resistant gasket 23 effectively reduces wear between components, prevents damage propagation, and improves the overall service life.

[0039] In the design of vibration control and damping systems, ensuring the robustness of damping components and their effective energy absorption capacity is crucial. For example... Figure 5 As shown, the flange 22 also has a receiving groove 24 inside, and the diameter of the end of the damping tenon 21 extending into the receiving groove 24 is larger than the opening of the receiving groove 24. The design of the receiving groove 24 gives the damping tenon 21 a more secure embedding effect during connection, effectively preventing the tenon from slipping off. By controlling the end diameter to be larger than the opening of the receiving groove 24, a self-locking effect is formed, ensuring the stability of the connection under vibration load and reducing the possibility of loosening and displacement. Compared with traditional planar connections, this significantly increases the reliability and durability of the connection. The self-locking function of the receiving groove 24 effectively resists dynamic loads caused by vibration and impact, providing higher load-bearing capacity, reducing the risk of loosening caused by improper assembly, and optimizing the dynamic response of the damping assembly.

[0040] Traditional vibration damping structures, under prolonged or high-load use, may experience component wear or failure due to excessive vibration, affecting the overall system performance and reliability. For example... Figure 5 As shown, the receiving groove 24 also includes an elastic element 25, which covers the outer periphery of the shock-absorbing tenon 21. By covering the outer periphery of the shock-absorbing tenon 21, the elastic element 25 provides better vibration energy absorption at all contact surfaces of the tenon. This covering structure effectively reduces direct friction between the tenon and the wall of the receiving groove 24, reduces wear caused by friction, and thus extends the service life of the component.

[0041] In some embodiments of this invention, the elastic element 25 is EPDM with a textured surface. EPDM possesses excellent UV resistance, ozone resistance, and heat resistance, making it an ideal choice for applications in various environments. By forming a textured surface on the EPDM, the contact area and friction at the interface can be increased, achieving more effective vibration absorption and energy dissipation.

[0042] like Figure 2 As shown, the sleeve assembly 12 also has reinforcing ribs at the connection between its outer periphery and the mounting plate 11. By using reinforcing ribs, the connection receives additional mechanical support, which can effectively disperse and offset concentrated stress under working load, thereby reducing the risk of fatigue failure that may occur due to long-term use. The reinforcing ribs not only enhance the rigidity of the sleeve assembly 12 and improve the reliability of the connection, but also provide a self-reinforcing mechanism for the entire damping system.
