[0014] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 7 The present invention will be further described below.

[0016] A modular vibration damping device includes: a steel column 1, a sliding sleeve 2 slidably connected to the outer wall of the steel column 1, two steel crossbeams 3 movably inserted into the interior of the sliding sleeve 2, a sliding hole 4 on the top surface of the sliding sleeve 2, a splicing component inside the sliding hole 4, an operating cavity 6 inside the steel crossbeams 3, the sliding hole 4 communicating with the operating cavity 6, two first guide holes 13 on the inner top wall of the operating cavity 6, a guide groove 11 inside the sliding hole 4, and two second guide holes 14 on the inner bottom wall of the guide groove 11. The operating cavity 6 is connected to the second guide hole 14 and has a spring-loaded component inside. The splicing component can squeeze the spring-loaded component along the second guide hole 14 and the first guide hole 13. The operating cavity 6 has a limiting component inside, which is connected to the spring-loaded component and restricts the movement direction of the spring-loaded component. The splicing component includes: an operating block 5, which is movably connected inside the sliding hole 4. Two splicing blocks 9 are fixedly connected to the outer wall of the operating block 5. Two splicing grooves 8 are opened in the inner top of the operating cavity 6, and the splicing blocks 9 are movably engaged with the splicing grooves 8.

[0017] Specifically, the rebound component includes: a movable block 7, which is slidably connected inside the operating cavity 6, and a first return spring 12 is fixedly connected to the inner top wall of the movable block 7, with one end of the first return spring 12 connected to the inner bottom wall of the operating cavity 6.

[0018] In this embodiment, the movable block 7 is configured to compress the first reset spring 12 when it moves downward. The first reset spring 12 will contract, and when the compressive force weakens, the potential energy of the first reset spring 12 is released, causing the movable block 7 to reset.

[0019] Specifically, the inner bottom wall of the guide groove 11 has two parking grooves 10, which are adapted to the size of the splicing block 9.

[0020] In this embodiment, before the sliding sleeve 2 and the steel beam 3 are spliced, the splicing block 9 will be located inside the parking groove 10. The parking groove 10 supports the splicing block 9, thereby ensuring that the operating block 5 is located inside the sliding hole 4 and will not fall off.

[0021] Specifically, the limiting component includes two limiting grooves 20, both of which are opened on the inner bottom wall of the operating cavity 6. A limiting rod 21 is movably inserted into the inside of the limiting groove 20, and one end of the limiting rod 21 is fixedly connected to the moving block 7.

[0022] In this embodiment, by setting the limiting rod 21, when the moving block 7 moves downward under the squeezing force of the operating block 5, the moving block 7 will drive the limiting rod 21 into the interior of the limiting groove 20. When the operating block 5 rotates on the moving block 7, the moving block 7 cannot rotate due to the restriction of the limiting rod 21, thereby ensuring that the moving block 7 will not rotate with the rotation of the operating block 5, thus avoiding affecting the normal use of the first reset spring 12.

[0023] Specifically, a fixing frame 15 is fixedly connected to the outer wall of the steel column 1, and several cylinders 16 are fixedly connected to the top surface of the fixing frame 15. A piston 18 is slidably connected inside the cylinder 16, and a moving rod 17 is fixedly connected to the top surface of the piston 18. One end of the moving rod 17 extends to the outside of the cylinder 16 and is fixedly connected to the sliding sleeve 2.

[0024] In this embodiment, when the piston 18 is subjected to vibration, the sliding sleeve 2 drives the steel beam 3 to move downward. When the sliding sleeve 2 moves, it will drive the moving rod 17 and the piston 18 to move, so that the piston 18 squeezes the air inside the cylinder 16, thereby generating a certain resistance and achieving a damping effect.

[0025] Specifically, a second return spring 19 is fixedly connected to the top surface of the cylinder 16, and one end of the second return spring 19 is fixedly connected to the sliding sleeve 2.

[0026] In this embodiment, the second return spring 19 is compressed when the sliding sleeve 2 moves downward, causing the second return spring 19 to contract. The contraction generates a reverse force, which buffers the connection between the steel column 1 and the steel beam 3, reducing damage to the connection.

[0027] The working principle and usage process of this utility model are as follows: During emergency setup, workers can insert one of the steel beams 3 into the sliding sleeve 2. At this time, workers can lift the operating block 5 on the side corresponding to the steel beam 3, thereby moving the splicing block 9 from the inside of the parking groove 10 to the inside of the guide groove 11. Then, after rotating it 90 degrees clockwise, the splicing block 9 is positioned above the second guide hole 14. Then, workers move the operating block 5 downwards, allowing the splicing block 9 to enter the operating cavity 6 through the second guide hole 14 and the first guide hole 13. At this time, the operating block 5 will press the moving block 7. After being pressed, the moving block 7 moves downwards and presses the first return spring 12. Simultaneously, the moving block 7 will drive the limiting rod 21 into the limiting groove 20, and then the operation... Personnel can rotate the operating block 5 counterclockwise by 90 degrees, causing the operating block 5 to drive the splicing block 9 to rotate on the top surface of the moving block 7 until the splicing block 9 corresponds to the splicing groove 8. At this time, the potential energy of the first reset spring 12 is released, causing the moving block 7 and the limit rod 21 to reset and lift the operating block 5, so that the splicing block 9 enters the interior of the splicing groove 8. Following the above operation, another steel beam 3 can be spliced ​​together with the sliding sleeve 2, thereby connecting the sliding sleeve 2 and the steel beam 3, achieving the effect of splicing the steel column 1 and the steel beam 3. In emergency construction, the splicing efficiency is high. Compared with the existing technology, this application achieves the splicing effect through a quick snap-fit ​​method, without the need to use a large number of bolts to connect the joints or to weld the joints multiple times. It is suitable for emergency construction scenarios.

[0028] When subjected to vibration, the sliding sleeve 2 causes the steel beam 3 to move downwards. As the sliding sleeve 2 moves, it also moves the moving rod 17 and the piston 18, causing the piston 18 to compress the air inside the cylinder 16, thus generating a certain resistance and achieving a damping effect. At the same time, as the sliding sleeve 2 moves downwards, it compresses the second return spring 19, causing the second return spring 19 to contract. This contraction generates a reverse force, which buffers the connection between the steel column 1 and the steel beam 3, reducing damage at the connection and further improving safety.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
