Slide rail structure for fixing power supply to machine frame

A slide rail structure for fixing a power supply to a machine frame, the slide rail structure being disposed between the machine frame and the power supply to guide the power supply to be mounted into the machine frame, the machine frame including at least two longitudinal left racks and at least two longitudinal right racks at two sides thereof, the slide rail structure comprising:

• two inner slide rails, one inner slide rail being laterally fixed to the two left racks, the other inner slide rail being laterally fixed to the two right racks, each of the inner slide rails including a bottom plate and a pair of side plates extending laterally along a top edge and a bottom edge of the bottom plate, a U-shaped groove with an opening facing inward being defined between the bottom plate and the pair of side plates;
• two outer slide rails, laterally locked to two sides of the power supply respectively, each of the outer slide rails including a bottom plate and a pair of side plates extending laterally along a top edge and a bottom edge of the bottom plate, a U-shaped groove with an opening facing outward being defined between the bottom plate and the pair of side plates, the outer slide rails being slidably connected to the corresponding inner slide rails and sliding in a same direction to form a supporting function;
• the bottom plate of each of the inner slide rails is provided with a stop plate relative to a front end of the power supply, the stop plate is provided with a rectangular hole, the stop plate is perpendicular to the bottom plate of the corresponding inner slide rail, the bottom plate of each of the outer inner rails is provided with a limiting piece corresponding to the rectangular hole relative to a rear end of the power supply, and the limiting piece is inserted in the rectangular hole to form a blocking function.
