Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, and in particular to a viscous damper with high stability. Background Technology

[0002] Viscous dampers, also known as viscous dampers, are dampers that are related to the speed of piston movement and function through fluid motion. Their structure includes a cylinder, piston, damping orifice, viscous fluid, and guide rod. The design and application of viscous dampers are of great significance for ensuring structural safety and improving seismic performance. Their working mechanism, application areas, and practical effects have been widely used and recognized in the fields of architecture and engineering.

[0003] Traditional viscous dampers have some drawbacks. During the installation process, due to the limited installation location, they often cannot effectively adapt to the actual working conditions and are difficult to make adaptive adjustments, which in turn affects the installation stability. After long-term use, especially when performing displacement detection on circular plates, the lack of obvious displacement indicators makes it difficult to accurately judge the positional changes, ultimately affecting the accuracy of the maintenance results. Utility Model Content

[0004] The main objective of this invention is to provide a highly stable viscous damper that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A highly stable viscous damper includes a viscous damper cylinder, a control rod, and a docking ring. An installation auxiliary mechanism is provided on the outer side of the docking ring. The installation auxiliary mechanism includes a fixed frame placed on the outer side of the docking ring. A guide rod is movably connected to the inner side of the docking ring. A limiting ring is fixedly connected to the outer side of the guide rod near the docking ring. The outer side of the guide rod near the limiting ring is slidably connected to the inner side of the fixed frame. An internally threaded ring is threadedly connected to the outer side of the guide rod near the fixed frame. A linkage frame is fixedly connected to one end of the guide rod. An indicator frame is fixedly connected to the upper end of the fixed frame. An observation slot is formed at the upper end of the indicator frame, and an indicator block is slidably connected to the inner side of the observation slot.

[0007] Preferably, a mounting plate is fixedly connected to the front end of the fixing frame, a limiting frame is fixedly connected to one end of the mounting plate, and a bolt is threadedly connected to the inner side of the limiting frame.

[0008] Preferably, one end of the limiting ring is in contact with one end of the fixing frame, one end of the internal threaded ring is in contact with the other end of the fixing frame, and the linkage frame is located inside the indicator frame.

[0009] Preferably, the linkage frame and the indicator frame are slidably connected, and the lower end of the indicator block is fixedly connected to the upper end of the linkage frame.

[0010] Preferably, there are two sets of limiting frames, each set distributed at one end and the other end of the mounting plate, and there are two sets of bolts.

[0011] Preferably, the outer side of the control rod is installed inside the viscous damper cylinder, the lower end of the docking ring is installed at the upper end of the control rod, there are two sets of docking rings, and the other set of docking rings is installed at the lower end of the viscous damper cylinder. There are two sets of installation auxiliary mechanisms, and both sets of installation auxiliary mechanisms are installed on the outer side of the two sets of docking rings.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By loosening the internal threaded ring and then pulling the fixing bracket, the fixing bracket drives the indicator bracket to slide along the linkage bracket, so that the indicator block points to the new position of the indicator bracket. Also, the mounting plate can be rotated, so that the mounting plate drives the fixing bracket to rotate around the guide rod as the axis. This can make it easier for the mounting plate to fully fit the installation position, thereby improving the stability of the viscous damper cylinder and enabling the viscous damper cylinder to achieve a high stability.

[0014] 2. If the viscous damper cylinder body is displaced, the viscous damper cylinder body will drive the docking ring to move via the control rod, and the docking ring will pull the guide rod to move, and the linkage frame will slide inside the indicator frame, causing the indicator block to move in the observation slot. At this time, when the worker is inspecting, he can observe the position of the indicator block in the observation slot to accurately determine whether the viscous damper cylinder body has been displaced.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, a highly stable viscous damper includes a viscous damper cylinder 1, a control rod 2, and a docking ring 3. An installation auxiliary mechanism 4 is provided on the outer side of the docking ring 3. The installation auxiliary mechanism 4 includes a fixed frame 41 placed on the outer side of the docking ring 3. A guide rod 42 is movably connected to the inner side of the docking ring 3. A limiting ring 43 is fixedly connected to the outer side of the guide rod 42 near the docking ring 3. The outer side of the guide rod 42 near the limiting ring 43 is slidably connected to the inner side of the fixed frame 41. An internal threaded ring 44 is threadedly connected to the outer side of the guide rod 42 near the fixed frame 41. A linkage frame 45 is fixedly connected to one end of the guide rod 42. An indicator frame 46 is fixedly connected to the upper end of the fixed frame 41. An observation groove 47 is opened at the upper end of the indicator frame 46. An indicator block 48 is slidably connected to the inner side of the observation groove 47.

[0022] In this embodiment, a mounting plate 49 is fixedly connected to the front end of the fixing frame 41, a limiting frame 410 is fixedly connected to one end of the mounting plate 49, a bolt 411 is threadedly connected to the inner side of the limiting frame 410, one end of the limiting ring 43 is in contact with one end of the fixing frame 41, one end of the internal threaded ring 44 is in contact with the other end of the fixing frame 41, the linkage frame 45 is located inside the indicator frame 46, the linkage frame 45 and the indicator frame 46 are slidably connected, the lower end of the indicator block 48 is fixedly connected to the upper end of the linkage frame 45, there are two sets of limiting frames 410, the two sets of limiting frames 410 are distributed at one end and the other end of the mounting plate 49, and there are two sets of bolts 411.

[0023] Specifically, first, place the viscous damper cylinder 1 in the designated position, then loosen the internal threaded ring 44, allowing the guide rod 42 to slide within the fixed frame 41. Next, pull the mounting plate 49, causing it to move the fixed frame 41 along the guide rod 42, and causing the fixed frame 41 to slide the indicator frame 46 along the linkage frame 45, thus pointing the indicator block 48 to the new position of the indicator frame 46. Then, rotate the mounting plate 49, causing it to rotate the fixed frame 41 around the guide rod 42, allowing the mounting plate 49 to align with the installation position. Finally, screw the bolt 411 through the inside of the limiting frame 410 into the installation position. Tightening the internal threaded ring 44 generates greater friction between the internal threaded ring 44 and the fixed frame 41, allowing the viscous damper cylinder 1 to be installed at the designated position. By loosening the internal threaded ring 44 and pulling the fixed frame 41, the fixed frame 41 drives the indicator frame 46 to slide along the linkage frame 45, causing the indicator block 48 to point to the new position of the indicator frame 46. The mounting plate 49 can also be rotated, causing the mounting plate 49 to drive the fixed frame 41 to rotate around the guide rod 42, thus facilitating the mounting plate 49 to fully fit the installation position and improving the stability of the viscous damper cylinder 1, enabling the viscous damper cylinder 1 to achieve high stability.

[0024] In this embodiment, the outer side of the control rod 2 is installed in the inner side of the viscous damper cylinder 1, the lower end of the docking ring 3 is installed at the upper end of the control rod 2, there are two sets of docking rings 3, and another set of docking rings 3 is installed at the lower end of the viscous damper cylinder 1. There are two sets of installation auxiliary mechanisms 4, and both sets of installation auxiliary mechanisms 4 are installed on the outer side of the two sets of docking rings 3.

[0025] Specifically, through the action of the two sets of installation auxiliary mechanisms 4 and the docking ring 3, it is possible to facilitate the installation of the viscous damper cylinder 1 at the designated position, and through the action of the two sets of installation auxiliary mechanisms 4, both the upper and lower ends of the viscous damper cylinder 1 can be fixed.

[0026] Working principle:

[0027] In use, first place the viscous damper cylinder 1 in the designated position, then loosen the internal threaded ring 44, allowing the guide rod 42 to slide within the fixed frame 41. Next, pull the mounting plate 49, causing it to move the fixed frame 41 along the guide rod 42 and the fixed frame 41 to slide the indicator frame 46 along the linkage frame 45, thus pointing the indicator block 48 to the new position of the indicator frame 46. The mounting plate 49 can then be rotated, causing it to rotate the fixed frame 41 around the guide rod 42, allowing it to align with the installation position. Then, screw the bolt 411 through the inside of the limiting frame 410 into the installation position, and then tighten the internal threaded ring 44, generating greater friction between the internal threaded ring 44 and the fixed frame 41. This allows the viscous damper cylinder 1 to be installed in the designated position. If the viscous damper cylinder 1 shifts, it will cause the viscous damper to... The damper cylinder 1 is driven by the control rod 2 to move the docking ring 3, which in turn pulls the guide rod 42 to move, and causes the linkage frame 45 to slide inside the indicator frame 46. This causes the indicator block 48 to move within the observation slot 47. During maintenance, the worker can observe the position of the indicator block 48 within the observation slot 47 to accurately determine whether the viscous damper cylinder 1 has shifted. By loosening the internal threaded ring 44 and pulling the fixing frame 41, the fixing frame 41 causes the indicator frame 46 to slide along the linkage frame 45, thus pointing the indicator block 48 to the new position of the indicator frame 46. The mounting plate 49 can also be rotated, causing the mounting plate 49 to rotate the fixing frame 41 around the guide rod 42. This ensures that the mounting plate 49 is fully aligned with the installation position, thereby improving the stability of the viscous damper cylinder 1 and achieving high stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
