Description

Technical Field

[0001] The utility model relates to a compact lifting clothes drying rack drive. Background Art

[0002] The lifting clothes rack is mainly used for hanging and drying clothes. It is usually installed on the top of the house and is lifted and lowered by hand or motor drive. Electric lifting clothes racks generally need to be installed with a driver to control the lifting during use. There are many types of existing drivers, which can basically meet the needs of most areas. However, there are still certain limitations in use, which are mainly reflected in the following aspects: the existing lifting clothes racks and drivers are greatly affected by the installation environment during installation or use. Some spaces or locations will directly lead to the inability to install the lifting clothes racks and drivers. For the existing lifting clothes rack drivers, manufacturers have not made small and compact designs. To develop, just adjust the position of the clothes rack drive during the installation process to complete the installation of the clothes rack drive. The arbitrary adjustment of the clothes rack drive position or direction increases the resistance during the clothes rack lifting process, and also affects the use and service life of the clothes rack. Severely, it causes the clothes rack to be unable to be used normally, and also increases the difficulty of using the clothes rack. At the same time, the existing clothes rack drives are basically single-axis drives. To meet the requirements of clothes rack lifting, generally, it is necessary to match multiple transmission mechanisms, which makes the transmission more complicated, and invisibly increases the size and cost of the clothes rack drive. Therefore, it is necessary to develop a compact clothes rack drive to solve the problem that the clothes rack drive is difficult to install in some environments. Utility Model Content
