The utility model discloses an anti-loose thread assembly structure of a GPS (Global Positioning System) and a GPS device. The anti-loose thread assembly structure comprises an upper shell and a lower shell, the lower shell is in threaded assembly with the upper shell; the PCB assembly is arranged between the upper shell and the lower shell; the assembly face of the upper shell is provided with a slope block, the slope direction of the slope block rises in the thread rotating direction of the upper shell, and the assembly face of the lower shell is provided with an elastic piece matched with the slope block in a clamped mode. According to the utility model, the upper shell and the lower shell are assembled in a threaded connection mode, and a clamping structure in which the clamping block is matched with the elastic piece is additionally arranged at the threaded structure, so that the threaded structure between the upper shell and the lower shell is prevented from loosening. 本实用新型公开了一种GPS的防松螺纹装配结构及GPS装置，防松螺纹装
