Description

Technical Field

[0001] The invention belongs to the technical field of clothes drying racks, and in particular relates to a telescopic clothes drying rack. Background Art

[0002] With the development of urbanization, more and more people live in buildings, and drying clothes has become an issue that must be considered. In order to save precious indoor space and avoid affecting lighting, users of staircase buildings and elevator buildings generally use outdoor clothes drying racks if installation is allowed in the building.

[0003] The current outdoor telescopic clothes drying racks are all connected to the ends of the shear support frames with clothes drying rods, and the spacing between the clothes drying rods is basically equal, ranging from 25 cm to 35 cm, which makes it inconvenient to use. Because the clothes of adults are generally about 50 cm wide, 25 cm of space is required on both sides of the clothes drying rods. Therefore, when clothes are hung on the clothes drying rods, the clothes on the two adjacent clothes drying rods cannot be hung. Moreover, because the clothes are wide, they need to be stuffed in sideways and then hung straight, which is inconvenient to use and many clothes cannot be hung at one time. In addition, since the clothes are hung outdoors to dry, they are easily blown away by the wind. The problems of objects being lost, dirty and needing to be washed again, falling on other people's windows and being difficult to take, and being blown away and unable to be found have always troubled users. For high-rise residents of residential buildings, there is even a safety hazard of hangers falling and hitting passers-by. At the same time, since the clothesline of the outdoor clothes drying rack needs to be made very long in order to dry more clothes, the current outdoor clothes drying racks require people to hang clothes on various positions of the clothesline, and they need to lean out of the window far away, which poses a safety hazard; after hanging clothes in one position, they need to move to another place to hang clothes, which is inconvenient to use; many windows are equipped with anti-theft nets, and there is also the currently popular broken bridge aluminum alloy windows, which can be opened in a very small space, and it is very difficult for people to hang clothes on various positions of the clothesline.
