<p>The utility model provides a shell structure. The shell structure can absorb impact from outside. The shell structure is provided with a main body shell with a through hole, an upper portion external-installation component which is arranged at an upper portion of the main body shell, a rear cover which is arranged at a lower portion of the main body shell, a screw thread tube which is provided with an inner screw thread portion therein and is arranged in the through hole of the main body shell, a buffering component which is arranged between the screw thread tube and the through hole of the main body shell, a first screw thread component which is in screwed connected with the inner screw thread portion of the screw thread tube so as to fix the upper portion external-installation component on the main body shell, and a second screw thread portion which is in screwed connected with the inner screw thread portion of the screw thread tube so as to fix the rear cover on the main body shell. Thus, when the upper portion external-installation component and the rear cover are subjected to shock from outside, even if the shock is transferred to the screw thread tube through the first screw thread component and the second screw thread portion, the buffering component can absorb the shock transferred to the screw thread tube.</p> |
