Remove the curtain cloth and you will see that the curtain cloth is driven by rollers when the curtain is closed. Just brush some lubricating oil in the roller groove. If the drum is broken, it needs to be repaired by a professional master.

I recommend several maintenance methods to you: natural category: solid wood curtain rod, which is also the most traditional curtain rod, and is more suitable for traditional and classical decoration. Its advantage is that it has many colors and can be perfectly matched with furniture. Its disadvantage is that the solid wood is easy to deform and the warranty is complicated, which is suitable for the warm climate in the south. Rooms with warm T-air in the north will accelerate the deformation of solid wood tracks, so the treatment of solid wood strips is the key to the quality of solid wood strips. Metal: aluminum alloy and wrought iron decorative rod. Aluminum alloy poles can eliminate the defects of solid wood poles. However, due to the few colors, it is suitable to match the decoration style of modern home, and so is wrought iron. For metal poles, the thickness of poles is the key to quality, and surface treatment is the guarantee of service life. Therefore, when selecting metal poles, attention should be paid to the following surface treatment methods and the thickness of poles, which should generally not be less than 0.8. The best surface treatments are electrophoresis and electrostatic spraying. Non-metal: plastic-coated steel pipe pole, the latest plastic-coated wood grain pole, solves the problem that neither solid wood pole nor metal pole can solve. It has many colors, is environmentally friendly and will not be deformed. It is the best material to replace solid wood poles. At present, there are steel pipes coated with wood grain paper on the market, and this pole has a short service life. At present, the best plastic-coated wood grain pole is imported from Japan, which uses environmentally friendly materials, with light pulling sound and long service life.
