[0021] The sleeve 1, as the main structure of the seismic bracket, has a certain strength to ensure the stability of the overall structure; two symmetrical adjustment rods 2 are provided inside the sleeve 1, and the adjustment rods 2 can slide freely in the sleeve 1 along the length direction of the sleeve 1 to adapt to installation requirements of different heights.

[0022] The adjusting shaft is arranged in the middle of the sleeve 1 and can rotate freely. The adjusting shaft is provided with an adjusting gear 9, which is specifically located inside the sleeve 1, and the adjusting rod 2 is provided with a rack 20 meshing with the adjusting gear 9; by rotating the adjusting shaft, the adjusting gear 9 can be driven to rotate, and then the two adjusting rods 2 can be driven to move up and down, thereby realizing the lifting and lowering adjustment of the adjusting rods 2 in the sleeve 1.

[0023] Shock-absorbing components are mainly used to absorb and disperse the impact force caused by external forces such as earthquakes, thereby preventing vibration from causing damage to the pipeline.

[0024] The utility model effectively solves the problem that the height of the existing earthquake-resistant bracket cannot be adjusted during installation through the functions of the rotating shaft 3, the adjusting gear 9 and the adjusting rod 2, thereby improving the applicability and practicality of the earthquake-resistant bracket.
