The operation is simple and convenient. It has a beautiful and concise appearance, making the window frame look clean and neat, and making the whole room look spacious and simple. In order to enable the rolling curtain to be lifted and lowered vertically, an aluminum alloy rolling curtain lower rod is usually installed at the bottom of the rolling curtain to counterweight the rolling curtain so that it can always be in a tensioned state. At present, the common aluminum alloy rolling curtain lower rod structures on the market mostly directly use aluminum alloy profile structures for counterweight.

Although they have certain lightness and corrosion resistance, their cost is relatively high, and deformation may occur during long-term use, and a novel rolling curtain rod is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel rolling curtain rod, including a lower rod main body, a closing mechanism is arranged at one end of the lower rod main body, an installation hole is opened at one end of the lower rod main body, a metal counterweight rod is fixedly arranged in the installation hole, a reinforcing plate is fixedly arranged on the inner surface of the lower rod main body, and the lower rod main body is made of PVC material.
[0006] Preferably, two card slots are opened at one end of the lower rod main body, and the card slots are in a triangular structure.
[0007] Preferably, the closing mechanism includes two covers, and the two covers are arranged on the outer surfaces of both ends of the lower rod main body.
[0008] Preferably, two clamping blocks are fixedly connected to the inner surfaces of the two covers.
[0009] Preferably, the number of the reinforcing plates is two, and the two reinforcing plates are arranged obliquely.
[0010] Preferably, the two side surfaces of the cross-sectional shape of the lower rod main body are in a circular arc curve structure, and a rolling curtain clamping groove is opened at the top of the lower rod main body.
