Abstract: A protecting device of a computer data-accessing device is disclosed. The machine frame is installed with a front surface corresponding to the data-accessing device. The front surface has a movable door. Pivotal portions are installed at the front surface. The frame has a lock for locking the door. Therefore, by the pivotal connection of the pivotal portions and the machine frame, the lock is used as an openable free end. By the locking relation of the lock and the machine frame, the door can be opened or closed. When the door is opened, the hard disk can be drawn out, and when the door is closed, the hard disk drive will not fall down, or is not intruded by other objects. Moreover, another side of the machine frame is installed with an openable fan device so that the hard disk drive has a preferred heat dissipating effect.

Abstract: The present invention relates to an interface card fastener, which is set in a computer system host or any other electronic device comprising expansion slots, comprising a bracket and a plurality of pivot assemblies. The bracket is set upon the frame above the expansion slots inside the chassis, and comprises a back frame engaged with the chassis and a plurality of the inner frames extended from the back frame. Each two inner frames define a fasten chamber, and the back frame comprises a horizontal extended L-shape hook in the appropriate position. The pivot assembly is set in the fastener chamber, which rotates between the fastening and the release positions of the interface card, and comprises a hook and a handle linked with the hook. To operate the fastener, pushing the handle directly to hook with the L-shape hook or unhook in interface card positioning, which is easy operating and stable positioning.

Abstract: A positioning and heat dissipating device of an interface card comprises an operation platform and at least one heat-dissipating module. The heat-dissipating module is fixed to a platform. The heat dissipating effect of the heat-dissipating module is correspondent to the interface card in a casing. The heat-dissipating module has an independent fan and a frame for installing the fan. A plurality of sliding grooves are formed on the frame; each sliding groove being installed with a positioning element movable on the sliding groove. A positioning portion on each positioning element presses a respective interface card so as to achieve the effect of positioning the interface card.

Abstract: A computer casing with reusable shielding pieces is disclosed. The computer casing has a plurality of expansion slots. Each expansion slot has an opening for mounting an information-accessing device. Each expansion slot has a shielding piece for covering the opening of the expansion slot. The size of each shielding piece is corresponding to the tracks so that the shielding piece is slidable along the tracks. Each shielding piece is formed with an engaging structure for being engaged with one side of the information-accessing device. Thereby, two opposite sides of the information-accessing device are engaged with the shielding pieces so that the information-accessing device is slidable along the tracks on the computer casing. As a consequent, the shielding pieces can be reused as an engaging structure for engaging an information-accessing device to a computer casing and no frame is required in the computer casing.

Abstract: A retainer for retaining interface card isolating pieces is disclosed. Especially, a retainer may retain a plurality of interface card isolating piece at one time. A press strip is installed on a positioning platform of a wire outlet of a computer casing. The press strip exactly presses interface isolating piece on the positioning platform. Two cam buttons are installed on the surface of the casing above the press strip. The cam buttons can be rotated and embedded into the cambered grooves at the top of the press strip so as to provide a pressure to the press strip. Therefore, by the press strip, all the interface cards can be fixed at one time. It is unnecessary to detach screws one by one. All the interface cards can be mounted or detached by fixing the press strip easily.

Abstract: An attachment device for attaching an expansion card having metal bracket to computer's back panel is disclosed. The device comprises a body having one side secured to the computer's back panel and a plurality of sliding members slidable in the body wherein after the expansion card has engaged with the computer's back panel by the body, each of the sliding members may slide from a first position in the body to a second position for quickly securing the expansion card to the computer' back panel.
