Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a composite viscous damper. Background Art

[0002] At present, the composite viscous damper is an existing damper, which combines the advantages of multiple materials and technologies. It consumes the structural vibration energy through the shear deformation of the viscous material, thereby improving the seismic performance of the structure. This damper has been applied in actual engineering and has a wide range of applications and good shock absorption effects. Its basic principle is that when the structure is subjected to external excitation, the viscous material in the damper will undergo shear deformation, thereby generating a damping force, converting the structural vibration energy into heat energy, thereby reducing the vibration amplitude of the structure and improving the seismic performance of the structure. Since the composite viscous damper has a wide range of uses, structural optimization of the composite viscous damper is necessary.

[0003] For example, a viscous damper is disclosed in a Chinese utility model patent with announcement number CN212775303U. In the above-mentioned prior art, although a closed oil circuit circulation is formed between the first cavity and the second cavity to ensure that the viscous damper can effectively buffer and reduce shock, the size of the scene to which the composite viscous damper is applicable is basically fixed after production. When the installation space changes, it will become impossible to install. When encountering a smaller installation space, the composite viscous damper can be compressed and installed. When encountering a larger installation space, it is only possible to weld a mounting plate on the mounting seat to supplement the distance. Such welding is not only time-consuming and labor-intensive, but also causes the use of materials that are not originally necessary, resulting in increased installation costs. Therefore, it is necessary to design a composite viscous damper that can perform distance compensation during installation. Utility Model Content

[0004] In order to solve the technical problem that when a composite viscous damper encounters a larger installation space, it is necessary to increase the cost and time to weld an installation plate, the utility model provides a composite viscous damper.

[0005] The utility model is implemented by the following technical scheme: a composite viscous damper, comprising a damper body, both ends of the damper body are provided with mounting components for fixing the damper body, the interiors of the two mounting components are provided with compensation components for performing distance compensation when the installation distance is insufficient, one side of each of the compensation components is provided with a fixing component for fixing the compensation component after compensation, and one side of the two mounting components is provided with a display component for displaying the compensation distance.

[0006] Through the above technical solution, when the installation space is large, the compensation component is rotated to expand the installation component, so that installation can be carried out in a larger space.

[0007] As a further improvement of the above solution, the mounting assembly includes a mounting block rotatably mounted on one end of the damper body, a compensation block slidably sleeved on the mounting block, and a mounting plate fixedly mounted on one side of the compensation block.

[0008] Through the above technical solution, the installation block and the compensation block can be slid and unfolded, so that they can be installed in a larger installation space.

[0009] As a further improvement of the above scheme, sliding grooves are provided on both sides of the inner wall of the compensation block, and the compensation assembly includes a threaded column rotatably arranged inside each sliding groove and a compensation plate arranged between every two adjacent threaded columns, each of the compensation plates is threadedly matched with the adjacent threaded column, one end of each threaded column passes through the adjacent compensation block and extends to the outside where a rotating block is fixedly installed, and the other end of each threaded column is rotatably installed with the inner wall of the adjacent sliding groove.

[0010] Through the above technical solution, the rotation of the threaded column will cause the compensation plate to move with the mounting block, thereby performing distance compensation.

[0011] As a further improvement of the above solution, a fixing groove is provided on one side of each mounting block, and each compensation plate is fixedly mounted to an adjacent mounting block through an adjacent fixing groove.

[0012] Through the above technical solution, the compensation plate is fixedly connected to the mounting block, thereby preventing the compensation plate from being separated from the mounting block due to angle problems.

[0013] As a further improvement of the above-mentioned scheme, the fixed component includes a limit plate fixedly installed on both sides of the compensation block and having a limit groove, a movable plate slidably installed inside each limit groove, and a fixed plate fixedly installed on one side of each movable plate, one side of each of the fixed plates is provided with a fixing opening adapted to the adjacent rotating block, and one side of each of the movable plates is fixedly installed with a limit spring having one end fixedly installed with the mounting plate.

[0014] Through the above technical solution, the fixed plate can fix the rotating block after it rotates, and the movement of the movable plate can release the fixing effect of the fixed plate on the rotating block.

[0015] As a further improvement of the above solution, the display assembly includes a connecting block rotatably mounted on one side of the compensation block and a scale fixedly mounted on one side of the connecting block.

[0016] Through the above technical solution, the specific amount of installation space that has been supplemented can be checked by rotating the scale.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model installs the damper body by setting an installation component, a compensation component and a fixing component. When the installation space is too large to install the damper body, the fixing component is used to release the fixing restriction effect of the compensation component so that the compensation component can be rotated. When the compensation component rotates, the installation component will be unfolded. The unfolding of the installation component will fill the larger installation space so that the damper body can be installed. This arrangement can not only install the damper body in installation spaces of different sizes, but also avoid the increase in cost due to the need for additional supplementary plate welding when installing the damper body.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 The composite viscous damper of this embodiment includes a damper body 1. Both ends of the damper body 1 are provided with mounting components for fixing the damper body 1. Compensation components for performing distance compensation when the installation distance is insufficient are provided inside the two mounting components. One side of each compensation component is provided with a fixing component for fixing the compensation component after compensation. One side of the two mounting components is provided with a display component for displaying the compensation distance.

[0026] Combination Figure 1-Figure 3 The mounting assembly includes a mounting block 201 rotatably mounted at one end of the damper body 1, a compensation block 202 slidably mounted on the mounting block 201, and a mounting plate 203 fixedly mounted on one side of the compensation block 202. The mounting block 201 and the compensation block 202 can be slidably unfolded and installed in a larger installation space.

[0027] Combination Figure 2 and Figure 3 Sliding grooves are provided on both sides of the inner wall of the compensation block 202. The compensation component includes a threaded column 301 rotatably arranged inside each sliding groove and a compensation plate 302 arranged between every two adjacent threaded columns 301. Each compensation plate 302 is threadedly matched with the adjacent threaded column 301. One end of each threaded column 301 penetrates the adjacent compensation block 202 and extends to the outside thereof to be fixedly installed with a rotating block 6. The other end of each threaded column 301 is rotatably installed with the inner wall of the adjacent sliding groove. A fixed groove is provided on one side of each mounting block 201. Each compensation plate 302 is fixedly installed with the adjacent mounting block 201 through the adjacent fixed groove. When the threaded column 301 rotates, the compensation plate 302 will move with the mounting block 201, thereby performing distance compensation.

[0028] Combination Figure 1 and Figure 2 The fixed component includes a limit plate 401 fixedly installed on both sides of the compensation block 202 and having a limit groove, a movable plate 402 slidably installed inside each limit groove, and a fixed plate 403 fixedly installed on one side of each movable plate 402, one side of each fixed plate 403 is provided with a fixing port adapted to the adjacent rotating block 6, one side of each movable plate 402 is fixedly installed with a limit spring 7 having one end fixedly installed with the mounting plate 203, the fixed plate 403 can fix the rotating block 6 after it rotates, and the movement of the movable plate 402 can release the fixing effect of the fixed plate 403 on the rotating block 6.

[0029] Combination Figure 2 The display assembly includes a connecting block 501 rotatably mounted on one side of the compensation block 202 and a scale 502 fixedly mounted on one side of the connecting block 501 .

[0030] The implementation principle of the composite viscous damper in the embodiment of the present application is as follows: when installing the damper body 1, if the installation space is large and the damper body 1 cannot be directly installed inside, pull the movable plate 402 to move the fixed plate 403, so that the fixed plate 403 will be separated from the rotating block 6, and then the rotating block 6 will rotate with the threaded column 301, and the rotation of the two threaded columns 301 will move the compensation plate 302, and the compensation plate 302 and the mounting block 201 are fixedly installed, so the rotation of the threaded column 301 will allow the mounting block 201 and The compensation block 202 slides and expands, so that the installation distance of the damper body 1 will be increased. According to the required expansion distance, by observing the scale 502, it can be known to what extent it needs to be expanded for installation. After the expansion is completed, the movable plate 402 is released, and the limit spring 7 will pull the movable plate 402 downward, allowing the fixed plate 403 to lock the rotating block 6 again to prevent the threaded column 301 from rotating by itself. This arrangement can not only install the damper body 1 in installation spaces of different sizes, but also avoid the need for additional supplementary plate welding to install the damper body 1, which increases the cost.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
