[0030] Specifically, the mounting seat 1 is designed with a threaded hole inside, which matches the thread of the bolt 2. By rotating the bolt 2, it is tightly screwed into the threaded hole of the mounting seat 1 to form a stable connection. This connection method ensures the tight fixation between the mounting seat 1 and the seismic support, effectively prevents the connection from loosening or falling off, and improves the stability of the overall structure. The linkage mechanism composed of the connecting block 7, the connecting rod 8 and the slider 11, and the elastic support of the spring 10. When an external force such as an earthquake acts, the connecting rod 8 will rotate according to the direction of the force, driving the slider 11 to slide in the slide groove 9, thereby squeezing the spring 10. The elastic deformation of the spring 10 can effectively absorb and disperse the impact force, reduce the direct impact of natural disasters such as earthquakes on the pipeline, and protect the safety of the pipeline. The telescopic rod 4 between the mounting seat 1 and the fixed plate 3. When the mounting seat 1 is subjected to an external force, the telescopic rod 4 can be telescopically deformed to relieve the impact force. The buffering function of the telescopic rod 4 further enhances the seismic performance of the device and effectively protects the pipeline from damage.

[0031] Reference Figure 1 , Figure 3 The protection component includes a connecting shell 12, the top of the connecting shell 12 is fixedly connected to the bottom of the connecting plate 5, the inner side of the connecting shell 12 is fixedly connected to a spring 13, the bottom end of the spring 13 is fixedly connected to an extrusion block 14, the ends of the connecting shell 12 are fixedly connected to a mounting plate 17, the outer side of the mounting plate 17 is fixedly connected to a protective shell 16, and the bottom of the extrusion block 14 is fixedly connected to a rubber pad 15.

[0032] Specifically, when an external force such as an earthquake acts, the spring 2 13 pushes the extrusion block 14 downward, so that the rubber pad 15 is in close contact with the protective shell 16 to form a buffer layer. The buffer layer formed by the elasticity of the rubber pad 15 and the rigidity of the protective shell 16 can further absorb and disperse the impact force, greatly reducing the impact on the pipeline and improving the safety of the pipeline.

[0034] Specifically, the connecting shell 12 and the protective shell 16 are fixed to the pipeline by rotating the bolt 18. This fixing method is convenient and quick. The expansion bolt 6 is fixed to the fixed object, and a strong gripping force is formed through its special expansion mechanism.

When a hard object falls, press the mounting base 1 downward, so that the mounting base 1 drives the telescopic rod 4 to extend and retract, buffering part of the force, and at the same time the connecting rod 8 drives the slider 11 to squeeze the spring 10. It is achieved to ensure that the connecting bracket will not cause unsatisfactory anti-seismic effect when a hard object falls when an external force such as an earthquake acts.
