For example, the existing viscous damper wall installation is one device per wall, which greatly increases the installation cost. Therefore, the existing needs are not met, and we propose a series viscous damper. Summary of the Invention

This series viscous damper achieves flexible construction of a series energy dissipation path through various mounting combinations of two dampers and series plates. It adapts to different wall spacings and space constraints, using series plates to bidirectionally transmit damping force to a single wall. Through mirrored, cross-linked, or arrayed layouts, it balances the force distribution on both sides of the wall and avoids localized stress concentration. The purely mechanical articulated structure ensures efficient transmission of seismic energy to the dual dampers, improving system reliability. 2. This series viscous damper features a stroke extension mechanism between the end of the second pin head, which is remote from the damper body, and the second ear plate. A transverse groove guide rail system provides a basic displacement transmission path and, combined with a disc spring, achieves primary impact cushioning. An adjustment rod-vertical groove structure converts linear displacement into rotational displacement, significantly extending the damper's equivalent stroke. The hydraulic closed-loop system utilizes oil circuit linkage to create adaptive reverse thrust enhancement, simultaneously improving energy efficiency. The torsion spring rotary damper provides precise reset while dissipating rotational energy, eliminating residual displacement. Through the synergistic effects of mechanical lever amplification, hydraulic feedback, and rotational energy dissipation, the damper overcomes the application bottleneck of small dampers and is suitable for high-intensity earthquake resistance scenarios with limited space.

The pin head 102 is rotatably connected to an ear plate 2, and the pin head 2 103 is rotatably connected to an ear plate 2 3 or a series plate 4. The damper 1 is provided with two dampers, namely a first damper and a second damper. The two dampers 1 can be installed in various combinations. The details are as follows: The ear plate 1 2 connected to the output end of the damper 1 is fixedly connected to the wall 1, and the ear plate 2 3 connected to the other end is fixedly connected to the wall 2. The two dampers 1 are arranged in a horizontal array, such as Figure 1 As shown; A series plate 4 is fixedly installed on the wall 2, and the two ends of the series plate 4 are rotatably connected to the pin head 2 103 of the non-output end of the two dampers 1. The ear plate 1 2 rotatably connected to the pin head 1 102 of the output end of the two dampers 1 is fixed on both sides of the wall 1. Figure 2 As shown; The ear plate 1 2 that is rotatably connected to the output end of the damper 1 is fixedly connected to the wall 1, and the ear plate 2 3 that is rotatably connected to the other end is fixedly connected to the wall 2. The two dampers 1 are mirror-imaged. Figure 3 As shown; A series plate 4 is fixedly installed on the wall 1, and the two ends of the series plate 4 are rotatably connected to the pin heads 2 103 of the non-output ends of the two dampers 1. The ear plates 2 rotatably connected to the pin heads 102 of the output ends of the two dampers 1 are respectively fixed on both sides of the wall 2. Figure 4 As shown; The ear plate 1 2 connected to the output end of the damper 1 is fixedly connected to the wall 2, and the ear plate 2 3 connected to the other end is fixedly connected to the wall 1. The two dampers 1 are arranged in a horizontal array, such as Figure 5 As shown; In the two dampers 1: the output end of the first damper is connected to the ear plate 1 2 which is rotatably connected and fixedly connected to the wall 1, and the other end is connected to the ear plate 2 3 which is rotatably connected and fixedly connected to the wall 2; the output end of the second damper is connected to the ear plate 1 2 which is rotatably connected and rotatably connected to the wall 2, and the other end is connected to the ear plate 2 3 which is rotatably connected and fixedly connected to the wall 1. Figure 6 As shown; Example 2: The technical problem in the above solution is that the small-sized damper 1 is easy to reach the maximum stroke under strong earthquake and lose the energy dissipation capacity. Figure 7-12 A series viscous damper, wherein a stroke extension mechanism 5 is provided between the end of the second pin head 103 away from the damper body 101 and the second ear plate 3; The stroke extension mechanism 5 includes: a transverse groove 502 provided on both sides of the ear plate 2 3; a connecting block 9 fixedly connected to the pin head 2 103, a cylindrical shaft 501 fixedly connected to both sides of the connecting block 9, the outer wall of the cylindrical shaft 501 is slidably connected to the inner wall of the transverse groove 502, the outer wall of the cylindrical shaft 501 is rotatably connected to the slider 503, the top and bottom ends of the slider 503 are provided with a guide groove 504, the top and bottom ends of the transverse groove 502 are provided with a guide groove 504, the top and bottom ends of the inner wall of the transverse groove 502 are fixedly connected with a guide rail 505, the outer wall of the guide rail 505 is slidably connected to the inner wall of the guide groove 504; the sliding cooperation between the cylindrical shaft 501 and the transverse groove 502 forms a basic displacement transmission path, and the sliding connection between the top and bottom guide grooves 504 of the slider 503 and the guide rail 505 is used to guide its movement; The outer side of the slider 503 is fixedly connected to a connecting rod 507. A sliding hole 508 is opened on the side wall of the transverse groove 502. The inner wall of the sliding hole 508 is slidably connected to the outer wall of the connecting rod 507. The outer wall of the connecting rod 507 is stacked with a disc spring 506; the disc spring 506 is compressed and deformed to absorb the initial impact kinetic energy, providing the first level of buffering and suppressing the peak load. During use: the relative movement of the wall pushes the damper body 101 to expand and contract, which in turn drives the second pin head 103 to move, and the cylindrical shaft 501 of the connecting block 9 slides laterally along the transverse groove 502 of the second ear plate 3; when the cylindrical shaft 501 slides, the disc spring 506 is compressed through the slider 503; A vertically extending groove 601 is provided on the connecting block 9. A fixed shaft 602 is fixedly installed on the inner wall of the groove 601. The fixed shaft 602 is coaxial with the cylindrical shaft 501. An adjusting rod 603 is provided on the inner side of the second ear plate 3. The bottom end of the adjusting rod 603 is fixedly connected to a circular sleeve 605. The inner wall of the circular sleeve 605 is rotatably connected to a rotating shaft 606. Both ends of the rotating shaft 606 are fixedly connected to the inner side of the second ear plate 3. A vertical slot 604 is formed on the adjusting rod 603. The inner wall of the vertical slot 604 is slidably connected to the outer wall of the fixed shaft 602. A damping pad 701 is installed on the inner wall of the vertical slot 604. A support frame 801 is fixedly installed on the right side of the second ear plate 3. The middle part of the support frame 801 is rotatably connected to a support frame 804. A fixed plate 703 is installed on the inner side of the support frame 804. A thrust spring 702 is fixedly installed on the inner side of the fixed plate 703. The end of the thrust spring 702 away from the fixed plate 703 is fixedly connected to the outer side of the adjustment rod 603. During use: the fixed shaft 602 is forced to slide along the vertical slot 604, converting the linear displacement into the rotational displacement of the adjustment rod 603. Through the lever ratio design (the inclination angle of the vertical slot 604 is controlled), the displacement is amplified, breaking the travel limit of the small damper. The circular sleeve 605 provides a wrap-around support for the rotating shaft 606, eliminating stress concentration at the root. A hydraulic rod 2 803 is fixedly installed on the inner side of the support frame 804, and the output end of the hydraulic rod 2 803 is fixedly connected to the fixed plate 703. A hydraulic rod 1 802 is fixedly installed on the support frame 801, and the output end of the hydraulic rod 1 802 is fixedly connected to the connecting rod 507; The oil chamber of hydraulic rod 1 802 is connected to the oil chamber of hydraulic rod 2 803; When in use: hydraulic rod 1 802 and hydraulic rod 2 803 are directly connected in the oil circuit to build a closed-loop force system: displacement of cylindrical shaft 501 → hydraulic pressure → compression of thrust spring 702 → rotation resistance of adjustment rod 603; rotation angle of adjustment rod 603 → reaction force → sliding resistance of cylindrical shaft 501; achieving two-way adaptive resistance enhancement The inner wall of the circular sleeve 605 is provided with a cylindrical groove 607, and a torsion spring rotary damper 608 is mounted on the inner wall of the cylindrical groove 607. The inner wall of the torsion spring rotary damper 608 is fixedly connected to the rotating shaft 606, and the outer wall of the torsion spring rotary damper 608 is fixedly connected to the inner wall of the cylindrical groove 607. When in use, a viscous damping torque is synchronously generated when the adjustment rod 603 rotates. The integrated torsion spring energy storage element allows the drive mechanism to accurately reset when the earthquake input weakens. A through slot 807 is provided on the hydraulic rod 803. The inner wall of the through slot 807 is slidably connected to a guide shaft 805. The left end of the guide shaft 805 is rotatably connected to the outer wall of the adjustment rod 603. When in use, the sliding fit between the guide shaft 805 and the through slot 807 eliminates interference with rotational motion and ensures smooth operation throughout the entire stroke. Working Principle: During earthquake input, the relative movement of the wall pushes the damper body 101 to expand and contract, which in turn drives the pin head 103 to move. The cylindrical shaft 501 of the connecting block 9 slides laterally along the transverse groove 502 of the lug plate 3. As the cylindrical shaft 501 slides, the slider 503 compresses the disc spring 506 (first-stage buffering), while simultaneously pushing the connecting rod 507 to drive the piston of the hydraulic rod 802. Hydraulic linkage stage: The oil pressure of hydraulic rod 1 802 is transmitted to hydraulic rod 2 803 through the pipeline, which pushes the fixed plate 703 to move, which compresses the thrust spring 702 (second-stage elastic energy storage). The thrust spring 702 pushes the adjustment rod 603 to rotate around the rotating shaft 606 (lever amplification effect). Stroke extension stage: When the adjusting rod 603 rotates, its vertical slot 604 and the fixed shaft 602 of the connecting block 9 produce relative sliding → converting linear displacement into rotational displacement (critical stroke amplification point); at the same time, the torsion spring rotary damper 608 provides resistance torque (energy consumption) and stores reset torque when the adjusting rod rotates.
