Abstract: A positioning structure pivotally disposed on a computer housing is provided. The positioning structure includes an assembly frame having first and second side walls, the first wall including a pivotal portion and a retaining portion. The first side wall further has a plurality of through holes being formed therethrough. The pivotal portion includes a pair of pivotal holes and a retaining portion projects from the first side wall and has a retaining hole formed therethrough. A positioning unit pivotally and releasably engages the pivotal holes of the pivotal portion. The positioning unit further includes a plurality of penetrating members which engage the through holes of the assembly frame and has a rotatable button being formed thereon. Rotation of the rotatable button allows for releasable locking of the positioning unit to the assembly frame.

Abstract: A frame structure of computer housing capable of unlocking and positioning is provided. The frame structure comprises a mobile seat and a housing frame. One side of the mobile seat forms an embedding part, and the other side thereof has at least one tenon. One side edge of the housing frame has an embedded portion corresponding to the embedding part. The embedded portion can be embedded into the embedding part. The housing frame has at least one through hole corresponding to and penetrated through by the tenon so that the mobile seas can be joggled on the housing frame. Quick assembling/disassembling, positioning and convenience can thus be achieved.

Abstract: The present invention provides a positioning structure pivotally disposed at a computer housing. The positioning structure comprises an assembly frame and a positioning unit. A pivotal portion, a retaining portion, and a plurality of through holes are disposed at an outside of each of two sidewalls of the assembly frame. One end of the positioning unit forms a pivotal end pivotally joined with the pivotal portion. The other end of the positioning unit forms a positioning end. A plurality of penetrating parts are disposed at an inside of the positioning end. The penetrating parts respectively correspond to the through holes, and can fix hardware parts. The positioning unit has a turn button thereon, which can make proper rotation on the positioning unit. The turn button can be retained with the retaining portion. Assembly and disassembly of hardware parts can thus be easily and quickly accomplished.

Abstract: A screwless disk drive frame positioning structure is disclosed. A floppy disk drive frame is hanged below the hard disk drive frame, and then a positioning structure on the front plate of a computer base is used to buckle the disk drive frames, or after the hard disk drive frame is combined with the floppy disk drive frame, the hard disk drive frame is hanged from an upper plate of a computer base. Then, the positioning structure on the front plate of the computer base serves to buckle the floppy disk drive frame. The positioning structure comprises a pressure suffering plate and two elastic elements. A bending plate having a concave portion extends from the middle portion of the pressure suffering plate. While the floppy disk drive frame is a “␣” shape plate. The lower side of the floppy disk drive frame is formed with a hooking plate folded outwards.

Abstract: A screwless wind conduit positioning device serves to position a wind conduit to a rear plate of a computer mainframe. The wind conduit is a curved tube having a heat dissipating fan at its lateral side. A front surface the wind conduit are formed with a plurality of tenons and hooks which are arranged at opposite sides. The rear plate of the computer mainframe has a thin plate on the surface thereof. The thin plate has a section with a plurality of wind vents arranged like the net. The periphery of the wind vents are installed with a plurality of engaging holes for being engaged with the tenons of the wind conduit. The hooks on the front surface of the wind conduit slide in a bank of wind vents on the section of the thin plate for being retained therein. Therefore, the wind conduit can be fixed to the rear plate of a computer mainframe without using any tool. Then a lateral plate with a folding plate is hooked to the rear plate, and then screws serve to fix the lateral plate to the rear plate.
