The right end of the right connecting rod 320 and the mounting seat 200 are respectively connected to the inner circumference and the outer circumference of the weak ring 410.

[0027] For example, Figure 1As shown, the cylinder body 100 is in a transversely extending cylindrical shape, the left and right ends of the cylinder body 100 are both closed and are provided with a sliding hole for the connecting rod to pass through, damping oil is arranged in the cylinder body 100, and a piston 300 is arranged in the cylinder body 100, the outer diameter of the piston 300 is slightly smaller than the inner diameter of the cylinder body 100, or the piston 300 is provided with a transversely arranged through hole, so that the damping oil in the space on the left side of the piston 300 and the damping oil in the space on the right side of the piston 300 can flow mutually; the left connecting rod 310 and the right connecting rod 320 They all extend laterally, and the left connecting rod 310 and the right connecting rod 320 can be arranged as an integral component and penetrate the piston 300, or the left connecting rod 310 and the right connecting rod 320 can be arranged as independent components and the right end of the left connecting rod 310 is fixedly connected to the piston 300, and the left end of the right connecting rod 320 is fixedly connected to the piston 300, or the left connecting rod 310, the right connecting rod 320 and the piston 300 can be arranged as an integral component; the left end of the left connecting rod 310 can be provided with a left connecting piece for connecting to an external building, and the left connecting piece can be a connecting ring.

[0028] The mounting seat 200 is disposed on the right side of the cylinder body 100. The mounting seat 200 is in the shape of a cylinder extending transversely. The mounting seat 200, the cylinder body 100, the left connecting rod 310 and the right connecting rod 320 are all coaxial. The left end of the mounting seat 200 is open and the right end is closed. Figure 2 The left end of the mounting seat 200 is sleeved on the outside of the cylinder body 100 from right to left, so that the part of the right connecting rod 320 passing through the cylinder body 100 is also arranged in the mounting seat 200. The left end of the mounting seat 200 and the cylinder body 100 can be fixedly connected by threaded connection, welding or other suitable methods to achieve relative fixation of the mounting seat 200 and the cylinder body 100; the right end of the mounting seat 200 can be provided with a right connecting piece for connecting to an external building, and the right connecting piece can be a connecting ring.

[0029] The mounting seat 200 is provided with a sleeve 400, and a connecting piece 420 is provided in the sleeve 400. The connecting piece 420 is overlapped with the right end of the right connecting rod 320, and a weak ring 410 is connected between the outer periphery of the connecting piece 420 and the inner wall of the sleeve 400. Figure 3 The right end of the sleeve 400 is connected to the mounting seat 200, and the connecting piece 420 is connected to the right connecting rod 320; the connecting piece 420 and the weak ring 410 are located on the right side of the sleeve 400, so that there is a certain amount of reserved space on the right side of the connecting piece 420, leaving enough space for the right connecting rod 320 to move to the right when the weak ring 410 is destroyed.

[0030] When in use, the left connecting rod 310 and the mounting seat 200 are installed on the building; by setting the weak link 410, under small earthquakes or common wind loads, the force transmitted between the right connecting rod 320 and the mounting seat 200 is small, and the weak link 410 will not be damaged, so the left connecting rod 310 and the mounting seat 200 are relatively fixed, and the building can maintain good stability and structural integrity; under large earthquakes, the force transmitted between the right connecting rod 320 and the mounting seat 200 is large, causing the weak link 410 to be damaged, and the left connecting rod 310 and the mounting seat 200 can be relatively displaced to consume vibration energy and meet the designer's expectations. When designing a preset start-up type viscous damper, the size of the weak link 410 and the material selection can be designed according to the preset destructive force, so that the weak link 410 can be damaged when the transmitted force reaches the preset value, so that the damper starts to consume vibration energy.

In this way, the mounting seat 200 and the cylinder body 100 are partially overlapped, and the contact area between the mounting seat 200 and the cylinder body 100 is large, which facilitates the connection between the mounting seat 200 and the cylinder body 100 to be more stable. The cylinder body 100 blocks the left end of the mounting seat 200, so that the weak ring 410 is isolated from the external environment, and the protection effect of the weak ring 410 is better.

[0033] In some embodiments of the present invention, a sleeve 400 is disposed outside the weak ring 410, a connecting piece 420 is disposed inside the weak ring 410, and the right connecting rod 320 and the mounting seat 200 are respectively connected to the connecting piece 420 and the sleeve 400. In this way, the force on the weak ring 410 is relatively balanced, which is convenient for calculating its force condition, and further facilitates design and manufacturing.
