[0002] The Roman rod refers to the horizontal rod for hanging curtains. The rod body is cylindrical with a diameter of about four centimeters. The length depends on the size of the window. There are gourd-shaped capitals at both ends of the rod, which serve as decoration. It is named after its style similar to ancient Roman architecture. The Roman rod body is fixed horizontally above the window. There is a groove on the rod as a slide rail, and a ring is put on the rod. There is a pulley on the ring that moves on the slide rail to drive the curtains to open and close.

[0003] The gourd-shaped end cap at the end of the Roman rod is mostly used to limit the ring to prevent the ring from separating from the Roman rod. Most of the existing end caps are fixed to the Roman rod by welding or threading. The welding fixing method makes it impossible to disassemble it separately for replacement, and the maintenance cost is relatively high. The threaded fixing method causes it to have low firmness when fixed. Based on this, the utility model designs a curtain Roman rod end cap to solve the above problems. Utility Model Content
