Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to a unidirectional metal damper. Background Technology

[0002] In traditional unidirectional metal dampers, the top and bottom of the energy dissipation block are fixedly mounted on the corresponding plates. This causes the material to deform or even yield when the energy dissipation block is displaced in a direction other than the design displacement, which can easily reduce the service life of the energy dissipation block and cause the damper to malfunction.

[0003] Therefore, it is necessary to provide a new unidirectional metal damper to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a unidirectional metal damper that is easy to use, can provide good protection for the energy dissipation block, and can ensure the normal service life of the energy dissipation block.

[0005] To solve the above-mentioned technical problems, the unidirectional metal damper provided by this utility model includes: an upper connecting plate, an energy dissipation block installed at the bottom of the upper connecting plate, a lower connecting plate below the energy dissipation block, side baffles fixedly installed on the top of the lower connecting plate on both sides of the energy dissipation block, guide balls fixedly installed on the side of the two corresponding side baffles that are close to each other, and the side of the two guide balls that are close to each other contacting the energy dissipation block, and a limiting plate fixedly installed at the bottom of the energy dissipation block, the limiting plate being adapted to the guide balls.

[0006] Preferably, stainless steel plates are fixedly installed on both sides of the energy-consuming block, and the stainless steel plates are fixedly installed on the top of the limiting plate. The two stainless steel plates are respectively in contact with the corresponding guide balls on the opposite sides.

[0007] Preferably, the guide ball is cylindrical, and half of the guide ball is located outside the side baffle.

[0008] Preferably, the guide ball is semi-circular.

[0009] Preferably, the number of energy-consuming blocks is two or more, and the two or more energy-consuming blocks are linearly distributed.

[0010] Preferably, the bottom of the limiting plate is in contact with the lower connecting plate.

[0011] Compared with related technologies, the unidirectional metal damper provided by this utility model has the following advantages:

[0012] Beneficial effects:

[0013] This utility model provides a unidirectional metal damper. The bottom of the energy dissipation block is not directly fixed to the lower connecting plate. This design can effectively reduce material fatigue (such as metal fatigue) when the energy dissipation block undergoes non-design displacement, thereby effectively ensuring the service life of the energy dissipation block. The setting of the limiting plate and guide ball can prevent the energy dissipation block from detaching from the lower connecting plate without affecting the displacement of the energy dissipation block. The setting of the stainless steel plate can provide good protection for the energy dissipation block and ensure the normal offset of the energy dissipation block. Attached Figure Description

Figure 4 for Figure 3 The diagram shown illustrates the structure of the upper connection when it is displaced parallel to the side baffle. In the first embodiment of this utility model, the unidirectional metal damper includes an upper connecting plate 1. An energy dissipation block 3 is installed at the bottom of the upper connecting plate 1. A lower connecting plate 2 is provided below the energy dissipation block 3. Side baffles 4 are fixedly installed on the top of the lower connecting plate 2 on both sides of the energy dissipation block 3. Guide balls 5 are fixedly installed on the side of the two corresponding side baffles 4 that are close to each other. The side of the two guide balls 5 that are close to each other is in contact with the energy dissipation block 3. A limiting plate 6 is fixedly installed at the bottom of the energy dissipation block 3. The limiting plate 6 is adapted to the guide balls 5.

[0027] Stainless steel plates 7 are fixedly installed on both sides of the energy-consuming block 3. The stainless steel plates 7 are fixedly installed on the top of the limiting plate 6, and the two stainless steel plates 7 are respectively in contact with the corresponding guide balls 5 on the opposite sides.

[0028] In this embodiment, the stainless steel plate 7 is a mirror stainless steel plate, which can effectively reduce the friction between the stainless steel plate 7 and the guide ball 5.

[0029] In this embodiment, the guide ball 5 is cylindrical, and half of the guide ball 5 is located outside the side baffle 4.

[0030] The bottom of the limiting plate 6 is in contact with the lower connecting plate 2.

[0032] Beneficial effects:

[0033] This utility model provides a unidirectional metal damper. The bottom of the energy dissipation block 3 is not directly fixed to the lower connecting plate 2. This setting can effectively reduce material fatigue (such as metal fatigue) of the energy dissipation block 3 when it is in a non-design displacement direction, thereby effectively ensuring the service life of the energy dissipation block 3. The setting of the limiting plate 6 and the guide ball 5 can prevent the energy dissipation block 3 from detaching from the lower connecting plate 2 without affecting the displacement of the energy dissipation block 3. The setting of the stainless steel plate 7 can play a good protective role for the energy dissipation block 3, while ensuring the normal offset of the energy dissipation block 3.
