Detailed Description

The utility model is further described below with reference to the drawings and examples.

Referring to fig. 1-10, a synchronous structure for sliding rail pulling-out comprises a bottom rail 10, a middle rail 20, an upper rail 30, a lower sliding component 40 and an upper sliding component 50, wherein the lower sliding component 40 is arranged between the bottom rail 10 and the middle rail 20, the upper sliding component 50 is arranged between the middle rail 20 and the upper rail 30, a transmission component 80 is arranged on the middle rail 20, the synchronous structure further comprises a first rack 70 and a second rack 60 which are respectively meshed with the transmission component 80, the second rack 60 is fixedly arranged on the upper rail 30, and the first rack 70 is fixedly arranged on the lower sliding component 40 or the bottom rail 10.

According to the utility model, the second rack is arranged on the upper rail, so that the upper rail and the middle rail are required to synchronously move, and when the middle rail is blocked and cannot move, the upper rail cannot move. The synchronous movement has the advantages of ensuring the frequency of synchronous movement and avoiding the problem that only the upper rail moves.

Referring to fig. 3, the first rack 70 is fixedly disposed on the bottom rail 10.

Specifically, the lower sliding assembly 40 and the upper sliding assembly 50 are both provided with pulleys, the middle rail 20 slides relative to the pulleys of the lower sliding assembly 40, and the upper rail 30 slides relative to the pulleys of the upper sliding assembly 50.

Referring to fig. 4, the transmission assembly 80 includes at least a transmission gear 820 rotatably disposed on the center rail 20. The transfer gear 820 is intermeshed with the first and second racks 70 and 60, respectively.

The engagement transmission is such that when the upper rail is pulled out, it moves along with the upper rail 30 via the second rack 60, and because the first rack 70 is fixedly disposed on the bottom rail 10, the second rack 60 drives the transmission gear 820 to rotate, and during the rotation, the transmission gear 820 moves along the first rack 70, thereby driving the middle rail 20 to move relative to the bottom rail 10.

Referring to fig. 4 to 6, the transmission assembly 80 further includes a mounting bracket 810, the transmission gear 820 is rotatably disposed on the mounting bracket 810, and the mounting bracket 810 is glued or welded to the middle rail 20.
