Abstract:
1. An ultrathin slide rail, comprising: a reinforcing plate having: an upper edge and a lower edge each formed with a bent portion bent toward one side of the reinforcing plate; and a middle section formed with plural sets of through holes; a rear support having: an upper edge and a lower edge each formed with a bent portion bent toward one side of the rear support; one end formed with a bent section provided with a plurality of threaded holes; an inner corner formed with a set of threaded posts; and a middle section formed with two slots corresponding in position to two sets of the plural sets of through holes of the reinforcing plate, wherein the rear support is assembled by being fitted between inner surfaces of the bent portions of the reinforcing plate, and then passing screws or rivets through the two sets of through holes of the reinforcing plate and the corresponding slots, thereby securing the rear support to one end of the reinforcing plate; a front support having: an upper edge and a lower edge each formed with a bent portion bent toward one side of the front support; one end formed with a bent section provided with a plurality of threaded holes; an inner corner formed with a set of threaded posts; and a middle section formed with through holes corresponding in position to another two sets of the plural sets of through holes of the reinforcing plate, wherein the front support is assembled by being fitted between the inner surfaces of the bent portions of the reinforcing plate, and then passing the screws or the rivets through the another two sets of through holes of the reinforcing plate and the corresponding through holes of the front support, thereby securing the front support to an opposite end of the reinforcing plate; a main body having: an upper edge and a lower edge each formed with a U-shaped bent portion bent toward one side of the main body; through holes corresponding in position to the four sets of through holes of the reinforcing plate; and a ball bearing plate which is secured between inner surfaces of the U-shaped bent portions of the main body and has spaced ball holes each receiving a ball therein, wherein the main body is assembled by being fitted between inner surfaces of the bent portions of the rear support and of the front support, respectively, and then passing the screws or the rivets through the four sets of through holes of the reinforcing plate, the two slots of the rear support, the through holes of the front support and the through holes of the main body, thereby securing the main body to the reinforcing plate and sandwiching the rear support and the front support therebetween, in which the rear support can extend or contract by sliding along the reinforcing plate, allowing a distance between the rear support and the front support to be adjusted according to a span between two slide rail posts of a chassis, so that the slide rail can extend across slide rail posts; a first extension plate having an upper edge and a lower edge each formed with a U-shaped bent portion bent toward one side of the first extension plate, wherein the first extension plate can slide into the main body through one end thereof and thus fit between the U-shaped bent portions of the main body so as to slide within the main body; and a second extension plate configured for securing a host thereon, wherein the second extension plate has: an upper edge and a lower edge each formed with a reinforced flange; and a middle section formed with threaded holes or fastening holes and configured so that, when the host is secured to the second extension plate, the host is secured to the second extension plate through the threaded holes or the fastening holes, in which the second extension plate can slide into the first extension plate through one end thereof and thus fit between the U-shaped bent portions of the first extension plate so as to slide within the first extension plate.
