Abstract: A fixing structure applicable to multiple sizes of storage device includes an enclosure, which has an interior forming an accommodation space that receives a storage device of one of the multiple sizes to be inserted into the enclosure. The enclosure includes, in an upper portion of the interior thereof, at least one spring-biasing section, which applies a spring force to an upper surface of the storage device opposite thereto for positioning in a longitudinal direction. The enclosure includes therein positioning sections and retention sections respectively set on opposite lateral sides thereof for cooperating with lateral sides of the storage device for positioning in a lateral direction. A lid has an inside surface on which a supporting section is formed so that when the lid is mounted to and closing a front side of the enclosure, the supporting section is in engagement with the storage device to secure the storage device.

Abstract: The present invention relates to a structure of a screw-free adaptation rack, which includes a main casing including a carrying section to define an upper portion of the main casing as a primary accommodation space and a lower portion as a secondary accommodation space. A partition plate is arranged in the primary accommodation space for division into a first receiving space and a second receiving space. A retention mechanism retains at least one 2.5-inch hard drive in the primary accommodation space. The secondary accommodation space has two sidewalls with a pair of bumps and a pair of through apertures formed therein so that with position adjustment of a retained object, the bumps are fit into and thus retain the retained object, allowing the present invention to readily receive and retain a hard drive and a 3.5-inch floppy disk drive in a screw-free manner for extensive applications to various specifications.

Abstract: A tool-free fixation structure for a data storage device includes: a tray, a front end, center and rear end thereof being respectively formed with a position limiting portion, pressing portion, and elastic propping portion, an accepting space being formed between the position limiting portion and elastic propping portion, two propping sheets being respectively disposed on two sides of the elastic propping portion, and positioning columns being disposed on the tray at a lower side of the accepting space, an outer threaded portion being disposed on a circumference of each positioning column; a data storage device, threaded holes adapted to accept the corresponding positioning columns therein, being on a lower side thereof, an inner threaded portion being disposed in each threaded hole, thereby allowing the propping sheets to press against the data storage device, and achieving a tight engagement of the inner threaded portions with the corresponding outer threaded portions.

Abstract: The present invention relates to a structure of a screw-free adaptation rack, which includes a main casing including a carrying section to define an upper portion of the main casing as a primary accommodation space and a lower potion as a secondary accommodation space. A partition plate is arranged in the primary accommodation space for division into a first receiving space and a second receiving space. A retention mechanism retains at least one 2.5-inch hard drive in the primary accommodation space. The secondary accommodation space has two sidewalls with a pair of bumps and a pair of through apertures formed therein so that with position adjustment of a retained object, the bumps are fit into and thus retain the retained object, allowing the present invention to readily receive and retain a hard drive and a 3.5-inch floppy disk drive in a screw-free manner for extensive applications to various specifications.

Abstract: An adaptation device includes a lower casing member including a connection interface and forming a bottom slot in a front bottom, at least one retention flange on side walls, and pivot receiving holes in rear portions of the side walls. A retention board forms a connection interface receiving opening in a front end, rotation shafts on a rear end, and pawls on a bottom. The shafts are movably received in shaft slots defined in a rotary board. Pivots are formed below the shaft slots for being received in pivot receiving holes defined in the lower casing member. The rotary board has a hold-down plate. With a hard disk drive placed on the retention board and connected to a connection interface, the cover and the rotary board are closed forward to have the hold-down plate holding down the hard disk drive. The cover is then moved backward for fixation.
