U-shaped sliding rail

The utility model belongs to the technical field of die forming. The U-shaped sliding rail comprises a sliding rail body, the device comprises a first shell and a second shell, wherein the first shell and the second shell are U-shaped shells; the section along the vertical direction of the side wall of the U-shaped shell is U-shaped; the first shell is arranged in the second shell, the first shell and the second shell are pre-fixed through a transparent polyurethane film, a fixed gap is kept between the first shell and the second shell, and the gap is filled with organic pouring glue used for fixing the first shell and the second shell. According to the U-shaped sliding rail, the pressing die splicing technology is adopted in the forming process, compared with a U-shaped sliding rail manufactured through a traditional injection molding method, the internal stress of the U-shaped sliding rail is smaller, the phenomena of crazing, cracking and the like are not prone to occurring, the sliding rail is damaged, an
