Abstract

The invention relates to the lifting device technical field, in particular to a self-positioning lifting device. The self-positioning lifting device comprises a rack; a top plate and a bottom plate of the rack are fixedly connected through a plurality of vertical rods; a center shaft is vertically arranged between the top plate and the bottom plate in a penetrating manner; the bottom plate is provided with an engagement and disengagement lifting device driving the center shaft to move up and down; the upper portion of the center shaft is provided with a child wheel assembly, the middle portion of the center shaft is provided with a driving gear, and the lower portion of the center shaft is provided with a mother wheel assembly; the mother wheel assembly comprises a busbar wheel and a cylinder mother shaft which can be movably arranged between the busbar wheel and the center shaft in a penetrating manner; the two ends of the busbar wheel are provided with an upper pressing disk and a lower tray correspondingly; the upper pressing disk is connected with the ambient vertical rods through supporting bearings; and the lower tray is fixedly connected with the cylinder mother shaft. The self-positioning lifting device is reasonable in structure and can achieve lifting adjustment and any height stop of a mosquito net and a veiling support, a user can conveniently use the mosquito net, the detaching and cleaning convenience and the using safety are improved, the overall structure is simple and stable, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a self-positioning lifting device. Background technique [0002] Mosquito nets are common supplies we spend in the hot summer, which can effectively prevent mosquito bites. Compared with insecticides and mosquito coils, the use of mosquito nets has the advantages of environmental protection, health and safety, low carbon and low cost. There are various types of mosquito nets on the market, such as traditional mosquito nets, which are suspended at four corners, and mobile mosquito nets, which are supported by a foldable frame. These two types of mosquito nets have their own advantages in use. The disadvantage is that the structure is simple but the operation is inconvenient. In order to effectively improve the convenience of using mosquito nets, various lifting mechanisms for mosquito nets are produced, which greatly facilitates the daily use of mosquito nets. For exampl...
