Benefits of technology

Ensures smooth movement of the ball bushing with the sliding rail relative to the carrier rail, preventing server fall and impact damage, thereby prolonging the lifespan of the sliding rail assembly by maintaining alignment and stability during installation.

Problems solved by technology

However, because the server is heavy and its weight can reach 20 kgs, the sliding rail may impact the ball bushing 8 if it is not kept in perfect alignment with the carrier rail 7 during its insertion into the ball bushing 8, and the server may fall with the sliding rail out of the carrier rail 7 during installation.

Embodiment Construction

[0022]Referring to FIGS. 3-14, a ball bushing positioning structure of a sliding rail assembly for server in accordance with the present invention is shown, comprising a sliding rail 1, a carrier rail 2, a ball bushing 3, a release hook 4, and a release control member 5.

[0023]The sliding rail 1 is affixed to a server (not shown) and movable back and forth relative to the carrier rail 2.

[0024]The ball bushing 3 (see FIG. FIGS. 4-5 and FIGS. 10-12) is movably mounted between the sliding rail 1 and the carrier rail 2 to guide sliding movement of the sliding rail 1 smoothly. As seen in FIG. 6, ball bushing 3 carries a plurality of rolling balls 30 at predetermined intervals, and includes an opening 31, a narrow mouth 310 defined in a front side of the opening 31, opposing left and right stop edges 313;314 bilaterally and transversely disposed between the opening 31 and the narrow mouth 310, and opposing left and right guide edges 311;312 respectively and obliquely outwardly extended fro...

Abstract

A ball bushing positioning structure formed of a sliding rail, a carrier rail, a ball bushing, a release hook and a release control member is disclosed. When inserting the sliding rail with an affixed server into the ball bushing to a certain distance to release stop edges of upright guide walls of a retaining flange of the release hook from the stop walls of the ball bushing subject to the effect of the release control member, the ball bushing is moved with the sliding rail backwardly relative to the carrier rail, preventing falling of the server with the sliding rail out of the carrier rail and avoiding impact between the sliding rail and the ball bushing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to sliding rail assemblies and more particularly, to a ball bushing positioning structure of a sliding rail assembly for server, which uses a release hook to stop a ball bushing in a carrier rail positively in position and allows the ball bushing to be moved with a sliding rail upon insertion of the sliding rail into the carrier rail.[0003]2. Description of the Related Art[0004]Conventional two-stage or three-stage sliding rail assemblies for drawer commonly uses a ball bushing to smoothen sliding movement between two rails. When inserting one first rail, for example, a sliding rail, into a second rail, for example, carrier rail, after a maintenance or repair work, the sliding rail must be kept in alignment with the carrier rail accurately so that the sliding rail can be coupled to the ball bushing. To avoid impact damage of the ball bushing during insertion of the sliding rail, a ball bush...
