Abstract

A slide rail includes a first slide, a second slide, and a third slide, each of the first slide, the second slide, and the third slide comprising a pair of sidewalls. The first slide further includes a bottom wall, the pair of the sidewalls are extended from two edges of the bottom wall respectively. The second slide is received in a space bounded by the bottom wall and the sidewalls of the first slide; the sidewalls of the second slide extend out from the space to contact the sidewalls of the third slide.

Claims

1. A slide rail comprising a first slide, a second slide, and a third slide, each of the first slide, the second slide, and the third slide comprising a pair of sidewalls, wherein

the first slide further comprises a bottom wall, the pair of the sidewalls of the first slide are extended from two edges of the bottom wall respectively;

the second slide is received in a space bounded by the bottom wall and the sidewalls of the first slide;

the sidewalls of the second slide extend out from the space to contact the sidewalls of the third slide;

each of the sidewalls of the second slide comprises a first curve contacting the corresponding sidewall of the first slide, a first connection portion extending from the first curve, and a second curve extending from the first connection portion;

the two first connection portions extend toward each other, extension ends of the two second curves extend away from each other, thereby forming recesses in respective inner surfaces of the second curves; and

each of the sidewalls of the third slide comprises a clamp plate;

the two clamp plates extend toward each other and extension ends thereof are received in the corresponding recesses of the second curves, and

the extension end of each of the clamp plates is turned back to form a free end, and each of the free ends is parallel with the corresponding clamp plate.

2. The slide rail as described in claim 1, wherein the third slide comprises an installation plate, the two sidewalls of the third slide are extended from two edges of the installation plate respectively, the second curves of the sidewalls of the second slide extend out of the space bounded by the bottom wall and the sidewalls of the first slide to be received in a space bounded by the installation plate and the sidewalls of the third slide.

3. The slide rail as described in claim 1, wherein the second slide further comprises a plate, the sidewalls of the second slide are symmetrically extended from two edges of the plate respectively.

4. The slide rail as described in claim 3, wherein the plate comprises a flat panel and two end portions, the first curves of the two sidewalls of the second slide are connected to the two end portions, respectively.

5. The slide rail as described in claim 4, wherein the plate further comprises two second connection portions connecting the flat panel and the two end portions, respectively, the two second connection portions are inclined to the flat panel and the two end portions, the end portions are parallel with the flat panel.

6. The slide rail as described in claim 1, wherein the third slide comprises an installation plate, the sidewalls of the third slide are symmetrically extended from two edges of the installation plate respectively.

7. The slide rail as described in claim 6, wherein each of the sidewalls of the third slide further comprises a bent portion, the bent portions connecting the installation plate and the clamp plates.

16. The slide rail as described in claim 4, wherein the first connection portions of the sidewalls of the second slide are parallel with the end portions.

8. A slide rail comprising:

a first slide comprising a first plate and two first side plates extending from a same side of the first plate; and

a second slide received in the first slide, the second slide comprising a second plate comprising a flat panel and two second connection portions that are symmetrically inclined to the flat panel, and two second side plates extending from the second plate;

the two second side plates configured for contacting the two first side plates;

wherein the second plate further comprises two end portions being connected to the two second connection portions respectively and parallel with the flat panel;

each of the second side plates comprises a first curve being connected to the corresponding end portion and contacting the corresponding first side plate, a first connection portion extending from the first curve in a direction approaching the corresponding second connection portion, and a second curve extending from the first connection portion;

extension ends of the two second curves extend in a direction away from the corresponding second connection portions, thereby forming recesses in respective inner surfaces of the second curves;

the slide rail further comprises a third slide comprising two clamp plates extending toward each other; and

extension ends of the clamp plates are received in the corresponding recesses of the second curves, and

the two first side plates are extended from two opposite edges of the first plate and bent inward to be parallel to and over the first plate.

9. The slide rail as described in claim 8, wherein at least the two first side plates or the two second side plates are extended in a direction away from the first plate or the second plate, for generating a distance between the first plate and the second plate.

10. The slide rail as described in claim 8, wherein the third slide further comprises a third plate and two third side plates, so that the third slide is slidable relative to the second slide.

11. The slide rail as described in claim 10, wherein the two third side plates are extended from two edges of the third plate respectively.

12. The slide rail as described in claim 10, wherein each of the third side plates comprises a bent portion, the bent portions connecting the third plate and the clamp plates.

13. The slide rail as described in claim 12, wherein the clamp plates extend in a direction away from a side of the third plate.

14. The slide rail as described in claim 12, wherein the second side plates and the third side plates are contacted at the extension ends of the clamp plates, generating a distance between the second plate and the third plate.

15. The slide rail as described in claim 8, wherein the extension end of each of the clamp plates is turned back to form a free end, and each of the free ends is parallel with the corresponding clamp plate.
