The utility model relates to the technical field of
noise reduction nails, in particular to a hollow shock absorption and
noise reduction
nail structure. The hollow shock absorption and
noise reduction
nail structure comprises a nail body, an inner cavity is formed in the nail body, and a nail cap is installed at the
tail of the nail body in a sliding connection mode. An inner cavity formed in the nail body is filled with
metal sand and is provided with a
steel ball, and the
metal sand is distributed in the inner cavity on the two sides of the
steel ball; a protruding part is arranged at the
tail of the nail body, and a plurality of outwards-inclined inserting cavities distributed in an annular mode are formed in the protruding part. A plurality of annularly-distributed inserting pieces are fixedly embedded in the inner wall of the nail cap. According to the hollow shock-absorbing and noise-reducing
nail structure, the nail cap is knocked by a hammer, so that the inserting column slides along the inner cavity and tightly compresses the
metal sand, and the metal sand can be plastically deformed to absorb vibration energy, so that the metal sand on the two sides of the
steel ball can be deformed and the
impact amplitude on the steel ball is reduced; therefore,
internal stress generated when the nail body is impacted is effectively reduced, and the effect of reducing noise generated when the nail body is knocked by a hammer is achieved.
