Description

Mute buffer slide rail and slide rail assembly thereof

Technical Field

The utility model relates to a slide rail.

Background

The slide rail has a wide application range, and under some special use requirements, the opening or closing of the slide rail needs to be ensured to have a silencing effect. The conventional slide rail does not have a mute effect, and the part of the slide rail is usually realized by adopting more buffer parts and dampers for realizing the mute effect, so that the manufacturing cost is far higher than that of the common non-mute slide rail due to the more complicated structure.

SUMMERY OF THE UTILITY MODEL

In order to make up for the defects in the prior art, the utility model provides the sliding rail which is simple in structure and can well realize the silencing effect.

In order to solve the technical problems and achieve the technical effects, the utility model is realized by the following technical scheme:

a silent buffering slide rail comprises an outer frame, an inner frame and a ball retainer, wherein the inner frame is movably arranged in the outer frame, the ball retainer is arranged between the inner frame and the outer frame, a first buffering piece is fixed at one end of the outer frame, a rivet is fixed at one end of the inner frame, and the rivet can be connected with one end of the first buffering piece in an interference fit manner; a second buffer piece is fixed at the other end of the inner frame, and the ball retainer is positioned between the first buffer piece and the second buffer piece; and a blocking piece is arranged between the rivet and the second buffer piece, the blocking piece is fixed on the inner frame, and one side surface of the blocking piece can be blocked against the other end of the first buffer piece.

Furthermore, the first buffer piece comprises a body, two side wings of the body are respectively of a U-shaped structure, and a groove of the U-shaped structure is clamped on a frame of the inner frame; the end part of the body is a C-shaped notch, and the C-shaped notch and the rivet can form an interference fit connection relation.

Furthermore, a first interference piece is arranged on the inner side wall of the frame of the inner frame, a second interference piece is arranged on the inner side wall of the U-shaped structure, and the first interference piece and the second interference piece are mutually interfered to form larger friction force.

Further, the first and second interference members may be a protrusion-to-protrusion fit, a protrusion-to-recess fit, or a recess-to-protrusion fit.

A slide rail assembly comprises a pair of the mute buffer slide rails, the two mute buffer slide rails are mutually fixed through the respective inner frames, and the pulling directions of the two smooth outer frames of the mute buffer slide rails are opposite.

When the slide rail of the utility model is closed and opened: the ball retainer may be in a contact state with the second buffer member, may be in a contact state with the first buffer member, or is located between the first buffer member and the second buffer member, but wherever the ball retainer is located, under the action of the buffer members, the ball retainer keeps a silent state during impact, and when the slide rail is completely opened, the blocking piece is in buffer contact with the first buffer member, so that a silent effect is also achieved; when furling: in a similar way, the impact of the ball retainer is the effect of buffering the impact to keep the silence, and the outer frame is also the effect of buffering the impact through the matching of the first buffer piece and the rivet to keep the silence.

The utility model has the beneficial effects that:

1. the first buffer piece and the second buffer piece of the utility model make the movement impact of the ball retainer a silencing effect.

2. The first buffer piece is matched with the rivet, and the baffle piece is matched with the first buffer piece, so that the impact of completely opening and completely closing the outer frame is a silencing effect.

3. The first buffer piece is in interference fit with the rivet, so that mute limiting stop can be realized during closing, and resistance is provided for opening during pulling out; meanwhile, the braking force can avoid the situation that the drawer is automatically opened due to installation or site reasons.

4. In the slide rail assembly formed by the slide rails, after the first interference piece and the second interference piece in each slide rail are calculated and designed, the friction force between the first buffer piece and the inner frame of the two slide rails can be different, and the different braking effects of the outer frame and the inner frame of the two slide rails can be realized, so that the two slide rails in the slide rail assembly can be opened and closed sequentially.
