The quick-mount slide rail includes a bracket and a connector slide module. The bracket includes a side plate and a front plate extending perpendicularly from a front edge of the side plate, and having two through holes. The connector slide module is disposed on the bracket and is movable relative to the side plate among a plurality of locking positions. The connector slide module includes a connector sliding block that has a block body and two stepped cylindrical connectors extending respectively through the through holes. Each stepped cylindrical connector has cylindrical segments. Outer diameters of the cylindrical segments decrease sequentially and forwardly. When the connector slide module is moved to a selected locking position, one of the cylindrical segments of each stepped cylindrical connector protrudes forwardly from the front plate for at least a predetermined distance. ## Claims ### Claim 1 A quick-mount slide rail adapted to be disposed on a rack, the rack having a plate body and a plurality of disposition holes that are formed in the plate body, said quick-mount slide rail comprising: a bracket including a side plate that extends in a front-rear direction and an up-down direction perpendicular to the front-rear direction, and a front plate that extends perpendicularly from a front edge of said side plate in a left-right direction perpendicular to the front-rear direction and the up-down direction, and that is adapted to abut against the plate body of the rack, said front plate having two through holes that are arranged in the up-down direction; and a connector slide module disposed on said bracket, and movable relative to said side plate along the front-rear direction among a plurality of locking positions, said connector slide module including a connector sliding block that has a block body, and two stepped cylindrical connectors extending forwardly from said block body and extending respectively through said through holes of said front plate, each of said stepped cylindrical connectors having a plurality of cylindrical segments, outer diameters of said cylindrical segments decreasing sequentially and forwardly in the front-rear direction; wherein, when said connector slide module is moved to a selected one of the locking positions, one of said cylindrical segments of each of said stepped cylindrical connectors protrudes forwardly from said front plate for at least a predetermined distance and is adapted to be inserted into a respective one of the disposition holes of the plate body; wherein said bracket further includes two positioning plates extending from said side plate in the left-right direction, and located respectively over and under said block body of said connector sliding block, each of said positioning plates has a positioning slot wavy in shape, said positioning slot of each of said positioning plates has a plurality of positioning slot portions, said block body of said connector sliding block has at least one sliding slot formed through said block body in the up-down direction and extending in the left-right direction, said connector slide module further includes a positioning rod extending in the up-down direction through said at least one sliding slot and slidable along said at least one sliding slot, said positioning rod having opposite end portions that engage respectively and slidably said positioning slots of said positioning plates, and when said connector slide module is disposed at the selected one of the locking positions, said positioning rod is disposed at one of said positioning slot portions of said positioning slot of each of said positioning plates, and abuts against said positioning plates to prevent rearward movement of said positioning rod; and wherein said connector slide module further includes at least one positioning resilient member disposed in said at least one sliding slot for biasing said positioning rod, so as to position said positioning rod at a selected one of said positioning slot portions of said positioning slot of each of said positioning plates. ### Claim 2 (depends on 1) The quick-mount slide rail as claimed in claim 1, wherein said side plate of said bracket has at least one guiding groove extending in the front-rear direction, and said connector sliding block further has at least one guiding post protruding from said block body, engaging said at least one guiding groove, and slidable along the front-rear direction. ### Claim 3 (depends on 1) The quick-mount slide rail as claimed in claim 1, wherein: said connector slide module further includes two sliding sleeve cylindrical connectors respectively and slidably sleeved on said two stepped cylindrical connectors and each having a substantially cylindrical profile, and two first elastic members, each being clamped between a respective one of said two sliding sleeve cylindrical connectors and said block body of said connector sliding block; each of said sliding sleeve cylindrical connectors includes a cylindrical post connector portion, and a first abutment portion located rearwardly of said cylindrical post connector portion; and said two first elastic members are disposed for respectively biasing said two sliding sleeve cylindrical connectors forwardly so as to abut said first abutment portions of said two sliding sleeve cylindrical connectors against a rear side of said front plate, and for protruding said cylindrical post connector portions of said sliding sleeve cylindrical connectors forwardly and outwardly of said two through holes, respectively, for said at least predetermined distance. ### Claim 4 (depends on 3) The quick-mount slide rail as claimed in claim 3, wherein: said connector slide module further includes two sliding sleeve square connectors respectively and slidably sleeved on said two stepped cylindrical connectors and each having a substantially rectangular profile, and two second elastic members, each being clamped between a respective one of said two sliding sleeve square connectors and said block body of said connector sliding block; each of said sliding sleeve square connectors includes a square post connector portion for accommodating said cylindrical post connector portion of a respective one of said sliding sleeve cylindrical connectors, and a second abutment portion located rearwardly of said square post connector portion; and said two second elastic members are disposed for respectively biasing said two sliding sleeve square connectors forwardly so as to abut said second abutment portions of said two sliding sleeve square connectors against a rear side of said front plate, and for protruding said square post connector portions of said sliding sleeve square connectors forwardly and outwardly of said through holes, respectively, for said at least predetermined distance. ### Claim 5 (depends on 1) The quick-mount slide rail as claimed in claim 1, wherein: said connector slide module further includes two sliding sleeve square connectors respectively and slidably sleeved on said two stepped cylindrical connectors and each having a substantially rectangular profile, and two second elastic members, each being clamped between a respective one of said two sliding sleeve square connectors and said block body of said connector sliding block; each of said sliding sleeve square connectors includes a square post connector portion, and a second abutment portion located rearwardly of said square post connector portion; and said two second elastic members are disposed for respectively biasing said two sliding sleeve square connectors forwardly to abut said second abutment portions of said two sliding sleeve square connectors against a rear side of said front plate, and for protruding said square post connector portions of said sliding sleeve square connectors forwardly and outwardly of said through holes, respectively, for said at least predetermined distance.
