Abstract: A detachable inner sliding rail and server case mounting arrangement includes a server case having a plurality of hangers arranged in a line at one side thereof, each hanger defining a shank and a head, an inner sliding rail having a plurality of hanger holes spaced along the length thereof for hanging to the hangers of the server case, each hanger hole defining a large hole for the passing of the head of one respective hanger and a narrow slot for engagement with the shank of one respective hanger after insertion of the heads of the hangers through the large holes of the respective hanger holes and a horizontal displacement of the inner sliding rail relative to the server case, a spring plate affixed to the inner sliding rail adjacent to one hanger hole, and a stop member pivotally coupled to the spring plate.

Abstract: A sliding rail coupling structure includes an outer rail, an intermediate sliding rail slidable in and out of the outer rail and having two longitudinal sliding grooves at two sides, sliding bearing bushes coupled to and movable along the intermediate sliding rail, each sliding bearing bush holding a plurality of roller cylinders that are kept in contact between the top wall of the intermediate sliding rail and the top wall of the outer sliding rail and a plurality of rolling balls that are respectively kept in contact between the longitudinal sliding grooves of the intermediate sliding rail and the sidewalls of the outer sliding rail, a roller holder affixed to the intermediate sliding rail to support two support rollers that are respectively in contact with two bottom flanges of the outer sliding rail.

Abstract: A biaxial flow damper used in an auto-close mechanism of a sliding rail assembly is disclosed to include a cylinder body defining flow parallel flow chambers, two first end caps respectively mounted in the front and rear sides of the cylinder body to close one end of each of the flow chambers, two second end caps respectively mounted in the front and rear sides of the cylinder body to close the opposite end of each of the flow chambers, two pistons respectively slidably mounted in the flow chambers of the cylinder body, and two piston rods respectively connected to the pistons and respectively extending out of the first end caps at the front and rear sides of the cylinder body.

Abstract: A sliding rail assembly support frame and server frame mounting arrangement includes two server frames provided at front and rear sides inside a server, two support frames each having a flat frame base respectively affixed to front and rear ends of the outer rail of a sliding rail assembly and a mounting flange perpendicularly extended from one end of the flat frame base and a plurality of cylindrical mounting members provided at the mounting flange and selectively inserted through mounting holes on the server frames, and two clamping plates respectively clamped on the mounting members to secure the support frames to the server frames.

Abstract: A inner sliding rail mounting structure is disclosed to include a control plate pivoted with a front side thereof to an inner sliding rail of a sliding track assembly for engagement with a stop block of an intermediate sliding rail of the sliding track assembly to secure the inner sliding rail to the intermediate sliding rail, a slide pivoted to the rear side of the control plate and coupled to the inner sliding rail by a slip joint for biasing the control plate to disengage the control plate from the stop block of the intermediate sliding rail for allowing removal of the inner sliding rail from the intermediately sliding rail, and a carriage affixed to the rear side of the slide and holding a spring member against a locating block at the inner sliding rail for pulling by the user to force the slide to bias the control plate.

Abstract: A hidden type sliding rail assembly auto locking structure for drawer is disclosed comprised of a holder base, a slide, a coil spring member, a hook, a steel spring strip, a locking block, and an actuating block. When the outer sliding rail is moved outwards with the drawer, the actuating block pushes the steel spring strip to force the hook against the slide and to further force the locking block into a side notch and stopped at a stop edge at the holder base to prevent disconnection of the locking block, for enabling the coil spring member to return the drawer to the close position. Except the coil spring member, the holder base holds the other parts on the inside and keeps them from sight without the use of a cover, thereby saving much installation labor and time.

Abstract: A sliding rail assembly auto opening mechanism for drawer is disclosed to include a holder block affixed to the outer rail of a sliding rail assembly and defining two longitudinal sliding slots, a sliding hook slidably mounted in the longitudinal sliding slots, a spring member connected between the holder block and the sliding hook, and a rocker, which is pivoted to a pivot in the holder block and has a front locating rod insertable through guide-in groove, sliding groove, retaining groove and guide-out groove at the holder block to automatically lock the sliding rail assembly when the sliding rail assembly is received with the drawer in the desk and to automatically unlock the sliding rail assembly when the drawer is pushed backwards from the locking position over a predetermined distance.

Abstract: A sliding rail assembly auto locking structure for drawer is disclosed comprised of a holder base, a swivel hook, a slide, two return springs, an actuating block. When an arched block of the swivel hook is approaching a recess in the holder base for positioning, the arched block does not fall to the recess directly, and at this time, oblique guide grooves of the swivel hook are moved over associating guide blocks of the holder base to guide the arched block into the recess slowly and smoothly, and therefore the inner sliding rail of the sliding rail assembly is moved with the drawer smoothly without vibration.
