ABSTRACT:
The present invention provides a locking mechanism for an external optical disk drive. The locking member is positioned on the upper housing to release or lock the cover. The cover has a projection extending downwardly from its front end and three journals are integrally formed with the cover. Three grooves are defined on the upper housing and sized to receive three corresponding journals of the cover. Besides, both ends of a resilient member are respectively adapted to be received in hubs. The resilient member is restrained by the upper housing and the hubs. Viscous material can be applied between the hubs and the shallow shaft. When the locking member disengages from the opening of the cover, the cover will be opened smoothly due to the viscosity of the viscous material.
