Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying racks, in particular to a telescopic rod of a clothes drying rack. Background Art

[0002] Clothes drying racks usually use telescopic rods to control the height of clothes drying racks. The height control of the existing telescopic rods usually uses the rotation of the screw sleeve, and the deformation of the screw sleeve is used to squeeze the rod, increase the pressure on the rod, increase the friction between the rod and the screw sleeve, and use the friction to control the length of the telescopic rod. However, this control method will cause the telescopic rod to shrink when the load is too large, affecting the effect of drying clothes. At the same time, in order to ensure the bearing capacity of the telescopic rod, the existing telescopic rod will increase the number of rotations when installed, so that the pressure of the screw sleeve on the rod becomes greater, further deforming the rod, affecting the appearance. Therefore, in order to improve the bearing capacity of the telescopic rod, the telescopic rod of the clothes drying rack is designed. Utility Model Content
