Abstract
The utility model relates to a three-section-type hidden rail which comprises a fixed rail, a middle rail, a moving rail, two sets of first balls, two sets of second balls, an upper roller and a lower roller. The moving rail comprises an installation arm, an inner rail and a cross arm. The three-section-type hidden rail is characterized in that an upper rib is arranged on a cross wall of the moving rail, a middle rib is arranged on a cross wall of the middle rail, and each rib has a function of reinforcing. The upper roller is installed between the upper rib and the middle rib and can roll, and the lower roller is installed between the middle rib and a cross wall of the inner rail and can roll. First bending portions are arranged on the moving rail, and first arc-shaped sinking portions of the first bending portions are formed in two side walls of the moving rail. Second bending portions are arranged on the middle rail, and second arc-shaped sinking portions of the first bending portions are formed in two side walls of the middle rail. Third arc-shaped sinking portions are formed in two side walls of the inner rail. The first balls are arranged between the first arc-shaped sinking portions and the second arc-shaped sinking portions and can roll. The second balls are arranged between the second bending portions and the third arc-shaped sinking portions and can roll. The three-section-type hidden ball has the advantages of being simple in structure, convenient to install, low in manufacturing cost and the like.
