[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] Reference Figure 1-Figure 3As shown, an adjustable spring shock absorber for a centrifugal fan comprises a buffer box 1, on which a sealing door that can be opened and closed is provided, a mounting plate 2 for mounting the centrifugal fan is slidably installed on the buffer box 1, a limiting slide groove for slidingly fitting the mounting plate 2 is provided on the buffer box 1, and the mounting plate 2 can be guided and limited by the limiting slide groove, so that the mounting plate 2 can only perform linear motion in the vertical direction; a first guide rod 3 is slidably fitted on the mounting plate 2, and a first guide through hole is provided on the mounting plate 2 for slidingly fitting the first guide rod 3, and the first guide through hole can be used to A movable space is provided for the first guide rod 3 and it is guided and limited. A first limiting plate with a diameter larger than the first guide through hole is fixedly connected to the first guide rod 3. The first limiting plate can prevent the first guide rod 3 from detaching from the first guide through hole. A first spring seat 4 for use with the first guide rod 3 is placed under the mounting plate 2. The first spring seat 4 is movably mounted on the first guide rod 3. The first guide rod 3 provides positioning for the first spring seat 4 when it is placed, and limits the first spring seat 4, so as to ensure the stability of the first spring seat 4 during structural expansion and contraction.
