Problems solved by technology

[0004] In the prior art, when the drawer needs to be pulled out, the third slide rail and the second slide rail are pulled to extend out of the support frame along the axial direction of the first slide rail, but the third slide rail cannot wait for the second slide rail to open. Slide out the first slide rail first and then slide out along the second slide rail. This will make the second slide rail and the third slide rail bear a huge moment when pulled out and be more easily damaged, which will affect the stability of the slide rail. service life

Embodiment Construction

[0014] Please refer to Fig. 1 and Fig. 2, the preferred embodiment of the slide rail device of the present invention includes a first slide rail 10, a second slide rail 20 slidingly engaged with the first slide rail 10, a slide engage The third sliding rail 30 of the second sliding rail 20 , a positioning member 40 and an elastic element 50 .

[0015] The first slide rail 10 is an elongated body with a cross-section roughly in the shape of a "C", which includes a bottom wall and two opposite side walls, and an unlocking portion 12 protrudes inwardly from one end of the bottom wall at a predetermined distance. The unlocking portion 12 includes an unlocking slope 122 .

[0016] The second slide rail 20 is an elongate body with a cross-section approximately in the shape of a "C", which includes a bottom wall and two opposite side walls, and a substantially arc-shaped chute 22 is opened on the bottom wall at a predetermined distance from one end thereof. . The sliding slot 22 ha...

Abstract

A slide rail device includes a first slide rail provided with a unlocking part, a second slide rail and a third slide rail provided with a jamming part. The second slide rail is provided with a slide groove in which a sliding locating piece is mounted. The locating piece includes a first barrier part and a second barrier part. When the third slide rail is pulled outwards, the jamming part of the third slide rail butts against the first barrier part of the locating piece, which makes the second slide rail and the third slide rail pulled out synchronously. The unlocking part of the first slide rail butts against the second barrier part of the locating piece, which makes the locating piece move along the slide groove of the second slide rail and makes the first barrier part of the locating piece and the jamming part of the third slide rail separate from the jamming to unlock the third and the second slide rails. The second slide rail is provided with an elastic component which reposits the locating piece by butting against the locating piece. In order to pull out the second and the third slide rails synchronously, the slide rail device uses the first barrier part of the locating piece arranged on the second slide rail to butt against the blocking side of the third slide rail, which can reduce the stress of the second slide rail effectively.

Description

technical field [0001] The invention relates to a slide rail device. Background technique [0002] The slide rail device is a widely used device, usually used to connect two items that can move relative to each other, such as drawers, rack-mounted servers, etc. [0003] The common slide rail device has a three-section slide rail. The general three-section slide rail usually includes a first slide rail, a second slide rail and a third slide rail. Taking a drawer as an example, the first slide rail is fixed on the support The third slide rail is fixed on both sides of the drawer, and the second slide rail is connected between the first slide rail and the third slide rail as a bearing rail to extend the movable range of the drawer, and make the third slide rail The slide rail and the second slide rail can slide back and forth relative to the first slide rail along the axial direction of the first slide rail, so the drawer can be pulled out or pushed back freely through the sli...
