A damping slide rail with gear structure

Abstract

The invention discloses a damping slide rail with a gear structure, which includes two sets of guide rails, each set of guide rails includes an upper rail, a middle rail, a lower rail and a damping mechanism, and the upper rail and the lower rail are single-side open cavity structures , the middle rail is a side-standing U-shaped structure, the middle rail runs through the opening position between the upper rail and the lower rail, the upper rail surrounds the middle rail, an upper roller frame is arranged inside the upper rail, and the lower rail The lower roller frame is symmetrically arranged in the rail, the upper rack is arranged in the cavity of the upper rail at a position staggered from the upper roller frame, the lower rack is arranged in the cavity of the lower rail corresponding to the upper rack, and the side center of the middle rail A gear is provided at the bottom of the lower rail, and a mounting frame is connected to the bottom of the lower rail, and the damping mechanism is assembled on the mounting frame. The damping slide rail with a gear structure of the present invention effectively increases the internal volume ratio of the drawer, improves the overall balance and stability, can effectively prevent external dust or fluid from entering the interior and affect the transmission effect, and effectively improves the service life of the slide rail .

Description

technical field [0001] The invention relates to the technical field of slide rails, in particular to a damping slide rail with a gear structure. Background technique [0002] At present, the overall height of the existing gear damping slides on the market is relatively large, which reduces the internal volume ratio of the drawer, and the width of the damping slides is generally 19 to 20 mm. Shaking, the internal gear end face is almost flush with the side of the slide rail, and dust particles are easy to enter, causing the slide rail to run poorly and reducing the service life. The rollers installed inside the slide rail are mostly solid structures. Unable to continue to rotate, it is laborious to pull the drawer, the overall waterproof performance of the slide rail is not good, the surface wear resistance is not good, and it is easy to oxidize and rust, which accelerates the wear of the slide rail. Contents of the invention [0003] In view of the above, it is necessary ...

[0002] At present, the overall height of the existing gear damping slides on the market is relatively large, which reduces the internal volume ratio of the drawer, and the width of the damping slides is generally 19 to 20 mm. Shaking, the internal gear end face is almost flush with the side of the slide rail, and dust particles are easy to enter, causing the slide rail to run poorly and reducing the service life. The rollers installed inside the slide rail are mostly solid structures. Unable to continue to rotate, which makes the drawing of the drawer more laborious, the overall waterproof performance of the slide rail is not good, the surface wear resistance is not good, and it is easy to oxidize and rust, which accelerates the wear of the slide rail
