slide rail assembly

Abstract

A slide rail assembly includes an inner rail member, an outer rail member, an upper roller, a lower roller, a first abutting roller, and a second abutting roller. The inner rail member includes a support wall, an inner rail wall extending upward from the support wall, and an upper rail wall disposed at the top of the inner rail wall. The outer rail member includes a lower rail wall located below the upper rail wall and an outer rail wall extending upward from the lower rail wall. The upper roller is disposed on the inner rail wall and above the lower rail wall and can roll along the top of the lower rail wall. The lower roller is rotatably disposed on the outer rail wall and can be supported at the bottom of the upper rail wall. The first abutting roller is rotatably disposed on the inner rail member and can be used to abut against the outer rail wall. The second abutting roller is rotatably disposed on the outer rail member and can be used to abut against the inner rail wall, so that the inner rail member and the outer rail member can maintain stable sliding.

Above the rail wall, and can roll along the top of the lower rail wall, the lower roller is rotatably disposed on the outer rail wall about a second axis parallel to the first axis and can be supported at the bottom of the upper rail wall. The first abutting roller is rotatably disposed on the inner rail member about a third axis extending along the second direction. The side of the first abutting roller adjacent to the outer rail wall can be used to abut against the outer rail wall. The second abutting roller is rotatably disposed on the outer rail member about a fourth axis parallel to the third axis. The side of the second abutting roller adjacent to the inner rail wall can be used to abut against the inner rail wall. The outer rail member also includes a third mounting block disposed on the side of the outer rail wall adjacent to the inner rail wall. The third mounting block is located on the side of the lower roller opposite to the lower rail wall along the first direction. The slide rail assembly also includes a second buffer member disposed on the third mounting block and extending along the first direction toward the side opposite to the lower rail wall.
