Abstract: A securing device for slide rails of a servo cabinet includes a slide rail assembly and an end unit is connected to a distal end of the rail assembly. A hook unit is connected to the inside of the rail assembly and includes a hook which is pivotably connected to the rail assembly and extends through a slit of the end unit to hook to a rack post. An operation unit includes a block movably located in a groove formed on the inside of the rail assembly and biased by a spring. A tail end of the hook contacts either a top face or an inclined face defined in the top of the block so as to be positioned to hook to different shapes of holes of the rack post. The hook is released from the holes of the rack post when the block is pushed toward the end unit.

Abstract: A linear sliding structure of a laptop keyboard and cover case includes: a base member, a moving member, a sliding holder, a first resisting member, a second resisting member, and a ball. The ball is arranged in an accommodation portion of the sliding holder, such that two sides of the sliding holder where the ball is arranged come into contact with the base member and the moving member. The first resisting member and the second resisting member are respectively arranged at two ends of the base member to provide a resistance of an end position when the moving member undergoes a linear displacement. By way of the sliding holder where the ball is arranged, the linear displacement of the moving member extending toward one end is provided. A structure convenient for opening and closing is provided for the keyboard or the cover case.

Abstract: A connection device for connecting a rail to a rack post, includes a rail and a slidable unit. The slidable unit includes a first member and a second member, and three rivets connected the slidable unit to the rail. The first member includes multiple slots, and the second member includes multiple snapping holes. The first member includes a bent portion which has guide pillars to be inserted into through holes of the bracket of the rail. The slidable unit is slidable along the slots and the snapping holes relative to the rivets. A tongue extends from one inner end of each snapping hole so as to contact the rivet to lock the slidable unit relative to the rail.

Abstract: A slide track includes a slide track includes an inner track and a positioning member. The inner track includes a limiting groove and two positioning holes spaced from the limiting groove. The inner track further includes a hollow portion. The positioning holes are located between the limiting groove and the hollow portion. The positioning member further includes a stop portion and a pressing portion respectively extending away from two opposite sides of a base. The base includes two opposite faces between the stop portion and the pressing portion. A connection portion is formed on each opposite face of the base. A positioning portion is connected to each connection portion. Each positioning portion is positioned in one of the positioning holes of the inner track. The pressing portion is aligned with the hollow portion of the inner track. The stop portion is aligned with the limiting groove of the inner track.
