A gap compensation mechanism capable of self adaptive posture adjustment is disclosed, which comprises a base seat, having at least a fixation portion disposed thereon, the fixation portion having a flow path area disposed peripheral thereto; at least an adjustment unit, sleeved onto an outer rim of the fixation portion; and a filler, being filled within the flow path area. As such, a workpiece to be fixed may be disposed on a face of an adjustment unit. Further, the adjustment unit provides at least three freedoms for the altitude and two axial inclinations for self adaptively compensating a gap with any geometrical shapes and thus further adjusting the posture of the combined workpiece. After all the adjustments, a filler is filled to reinforce the structure and finally a fixation unit is employed for locking and fixing.

Gap compensation mechanism for self adaptive posture adjustment

A disc clamping device with self lock elements particularly for DVD-ROM or CD-ROM fixedly maintained on a turntable when disc is rotating in high speed. The device comprises a turntable having a boss on the center for putting disc thereon, and a disc clamping member tightly sleeved on boss having protuberances on periphery wherein protuberances are deformed inwards when biased by disc such that disc can insert through disc clamping member, and then protuberances return to original forms by elastically energized force for clamping disc on turntable. By utilizing this, the purposes of decreasing the umber of parts, easy assembly, and high precision positioning of disc are achieved.

Disc clamping device with self lock elements

A disc clamp mechanism for preventing a disc (e.g., DVD-ROM or CD-ROM) from slipping and/or loosening in a high speed rotation comprises a positioning member sized to the center hole of the disc having a hole for being mounted on a turntable, and an inclined surface; a helical spring within the positioning member; a disc-clamping member sized to the center hole of the compact disc having circumferential raised portions, recessed portions each extending from the raised portion, and flexible V-shaped members surrounded by two recessed portions and a raised portion; and an elastic plane-like member mounted on the positioning member. As such, the disc is secured by the raised portions, the inclined surface, and the turntable when loaded onto the disc-clamping member. This mechanism finds applications in the DVD-ROM or CD-ROM products. Further, a thinner construction, an easy assembly, and a high positioning precision are realized by this mechanism.
