slide rail device

Abstract

A slide rail device includes a first slide rail unit and a second slide rail unit. The first slide rail unit includes a first slide rail, a ball seat movably disposed on the first slide rail, and a retaining member disposed on the first slide rail. The first slide rail has a first end and a second end. A hook portion is formed at the end of the ball seat facing the second end. The retaining member has a mounting portion fixedly disposed on the first slide rail, a spring arm portion connecting to the mounting portion, and a pressing portion bending upward from the end of the spring arm portion and spaced apart from the first slide rail. The second slide rail unit includes a second slide rail movably disposed on the first slide rail and abutting against the ball seat. When the second slide rail extends relative to the first slide rail towards the second end, it can drive the ball seat to move towards the second end, causing the hook portion to engage with the spring arm portion, with a portion of the ball seat located between the first slide rail and the pressing portion.

Claims

1. A slide rail device, comprising: a first slide rail unit including a first slide rail, a bead seat movably disposed on the first slide rail, and a retaining member disposed on the first slide rail, the first slide rail having a first end and a second end opposite to the first end, a hook portion being formed at one end of the bead seat facing the second end, the retaining member having a mounting portion fixedly disposed on the first slide rail, a spring arm portion connecting the mounting portion, and a pressing portion bending upward from the end of the spring arm portion and spaced apart from the first slide rail; and a second slide rail unit including a second slide rail movably disposed on the first slide rail and abutting against the bead seat, wherein when the second slide rail extends relative to the first slide rail toward the second end, it can drive the bead seat to move toward the second end, so that the hook portion is engaged with the spring arm portion, and a portion of the bead seat is located between the first slide rail and the pressing portion.

2. The slide rail device as claimed in claim 1, wherein, The first slide rail forms a movable groove for the retainer to be movably positioned.

3. The slide rail device as described in claim 2, wherein, The spring arm has an elastic section extending along the length of the first slide rail and a stop section extending from the end of the elastic section away from the first slide rail, and the hook can be engaged with the stop section.

4. The slide rail device as claimed in claim 3, wherein, The hook has a guide slope. When the bead seat moves toward the second end, the hook abuts against the elastic section by the guide slope and pushes the elastic arm to deform downwards, finally causing the hook to lock in the stop section.

5. The slide rail device as claimed in claim 3, wherein, The second slide rail unit also includes an unlocking member disposed on the second slide rail. When the second slide rail moves back towards the first end relative to the first slide rail, the unlocking member abuts against the holding part and pushes the holding part and the spring arm part to deform downward elastically to release the locking relationship between the hook part and the stop section.

6. The slide rail device as claimed in claim 5, wherein, The unlocking component has a flat portion disposed on the second slide rail and an unlocking portion extending from the lower edge of the flat portion toward the first slide rail, the unlocking portion being able to abut against the holding portion.

7. The slide rail device as claimed in claim 6, wherein, The holding part has an abutting slope that can abut against the unlocking part.
