Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, the present invention discloses a spring 50 damping device convenient for adjustment, which includes a base 10 and a top plate 20 located at the upper side of the base 10.

A first annular column 11 is fixedly arranged on the base 10, a second annular column 21 is fixedly arranged on the lower side of the top plate 20, and the inner wall of the first annular column 11 is in threaded connection with the outer wall of the second annular column 21. The raising and lowering of the top plate 20 is achieved by rotating the second annular post 21.

An upper plate 30 is provided under the top plate 20, and a pivot bearing is provided between the upper plate 30 and the top plate 20 so that the top plate 20 can pivot with respect to the upper plate 30. An elastic component is arranged between the upper plate 30 and the base 10, the elastic component comprises a protruding column 41, a spring 50 and a locking piece 51, the protruding column 41 is fixedly arranged on the upper side of the base 10, and the lower end of the spring 50 is sleeved on the protruding column 41. The protruding columns 41 limit the lower end of the spring 50, thereby enhancing the stability of the spring 50.
