slide rail device

Abstract

A slide rail device includes a first slide rail unit and a second slide rail. The first slide rail unit includes a first slide rail and a ball seat movably disposed on the first slide rail. The first slide rail has a first base plate and two first sidewalls respectively connected to the upper and lower edges of the first base plate. The first slide rail unit also includes a plurality of auxiliary positioning members disposed on the upper and lower edges of the ball seat. The second slide rail is movably disposed on the first slide rail and abuts against the auxiliary positioning members.

Claims

1. A slide rail device, comprising: a first slide rail unit, including a first slide rail, a ball seat movably disposed on the first slide rail, and a plurality of auxiliary positioning members disposed on the upper and lower edges of the ball seat, the first slide rail having a first base plate and two first side walls respectively connected to the upper and lower edges of the first base plate, the auxiliary positioning members being respectively abutting against the first side walls; and a second slide rail movably disposed on the first slide rail and abutting against the auxiliary positioning members.

2. The slide rail device as claimed in claim 1, wherein, Each of the auxiliary positioning components has a positioning part that abuts against the first side wall, a neck that connects to the positioning part and passes through the bead seat, and a guide part that connects to the neck and abuts against the second slide rail.

3. The slide rail device as described in claim 2, wherein, Each of the first sidewalls forms a first groove, which is into which the positioning part of the corresponding auxiliary positioning member extends and abuts.

4. The slide rail device as claimed in claim 2, wherein, The second slide rail includes a second base plate and two second side walls that are respectively connected to the upper and lower edges of the second base plate. Each of the second side walls forms a second groove into which the guide portion of the corresponding auxiliary positioning member extends and abuts.

5. The slide rail device as claimed in claim 2, wherein, The bead holder has a base plate and two side plates bent from the upper and lower edges of the base plate, each side plate forming a plurality of through slots for the necks of the auxiliary positioning members to pass through.

6. The slide rail device as claimed in claim 2, wherein, The surface of the positioning part that abuts against the first side wall is a spherical arc surface.

7. The slide rail device as claimed in claim 2, wherein, The guide part has a guide surface that abuts against the second slide rail and a flush surface that abuts against the ball seat. The guide surface is a cylindrical arc surface and the flush surface is flush.

8. A slide rail device, comprising: a first slide rail unit, including a first slide rail, a ball seat movably disposed on the first slide rail, and a plurality of auxiliary positioning members disposed on the upper and lower edges of the ball seat, the first slide rail having a first base plate and two first side walls respectively connected to the upper and lower edges of the first base plate, the auxiliary positioning members respectively abutting against the first side walls; and a second slide rail movably disposed on the first slide rail.

9. The slide rail device as claimed in claim 8, wherein, Each of these auxiliary positioning components is integrally formed into the arc-shaped protrusion of the bead seat.

10. The slide rail device as claimed in claim 8, wherein, Each of the first sidewalls forms a first groove, which allows the corresponding auxiliary positioning elements to extend into and abut against.
