Abstract: A locking assembly includes a first locking member, a rotating shaft for driving the first locking member to move, and a shell member. The first locking member is movably coupled to the shell member. An elastic element is coupled between the first locking member and the shell member. A first protruding portion is provided on an outer peripheral side of the rotating shaft. One end of the first locking member is provided with a first abutting portion. The first protruding portion abuts against the first abutting portion. The elastic element is used to maintain mutual contact between the first protruding portion and the first abutting portion. The first protruding portion rotates along with the rotating shaft to drive the first locking member to extend from or retract into the shell member.

Abstract: The disclosure discloses an apparatus for assembling a multi-component structure. The apparatus for assembling includes a pushing member fixed to a first component, a latch unit corresponding to the pushing member, the latch unit fixed to a second component. when the first component is not installed to a predetermined position of the second component, the latch unit stays in a locking position to prevent the second component from being installed to a third component; when the first component is installed to the predetermined position of the second component, the latch unit stays in an unlocking position and the second component is released to be installed to the third component. A multi-component structure is further disclosed.

Abstract: A server casing using a sliding apparatus for easy insertion and removal of blade servers includes a chassis and the sliding apparatus. The chassis includes a blocking member. The sliding apparatus includes a first fastening plate, a second parallel fastening plate being mounted to the first fastening plate. A sliding plate is slidably connected to the second fastening plate. The sliding plate is received between first and second fastening plates and there is a locking member with first and second ends. The first end is rotatably connected to the second fastening plate and includes a locking portion, the second end is connected to the sliding plate. The locking portion can move between a locking position, where the locking member is locked by the blocking member, and an unlocking position, where the locking member is unlocked by the blocking member.

Abstract: A hard disk drive (HDD) module includes a bracket with two opposite sidewalls, an HDD, and a positioning element rotatably mounted between the sidewalls of the bracket. Each sidewall defines a leading slot and a latching slot communicating with the leading slot. Two blocks extend from opposite sides of the HDD. When the blocks enter the corresponding leading slots, the latching element is rotated to push the HDD to move, with the blocks moving into engagement with the corresponding latching slots, to assemble the HDD in the bracket.

Abstract: A cage nut includes a substantially rectangular base portion, two sidewalls, two stopper portions, two arm portions, two clamping portions, and a nut. The sidewalls extend from two opposite edges of the base portion. Each stopper portion extends from an end of a corresponding sidewall away from the base portion. The two stopper portions extend toward each other. Each arm portion extends outwardly from an end of a corresponding stopper portion. Each clamping portion extends from an end of a corresponding arm portion and includes a first side edge and a second side edge. The first side edge and the second side edge are arranged in an angle. The angle is equal to or less than about degrees. The clamping portions extend away from each other. The base portion, the two sidewalls and the two stopper portions define a receiving space. The nut is received in the receiving space.

Abstract: A mounting apparatus for hard disk drives includes a plate. A number of spaced supporting portions is formed on at least one of two opposite side surfaces of the plate. A row of first latches extend upward from a top side of the plate. A row of second latches extend downward from a bottom side of the plate. Two fixing holes are respectively defined in the top and bottom sides of the plate. The mounting apparatus can be mounted between a bottom wall and a top wall of an electronic device, and has no bent plates, thus will save space for receiving more hard disk drives.

The angle is equal to or less than about 90 degrees. The clamping portions extend away from each other. The base portion, the two sidewalls and the two stopper portions define a receiving space. The nut is received in the receiving space.
