A ring type mosquito net lifter

Abstract

The invention relates to the technical field of suspension attachment lifting devices, in particular to a ring type mosquito net lifting device. The ring type mosquito net lifting device comprises a rack. The rack is provided with a top plate and a bottom plate. A center shaft is vertically arranged between the top plate and the bottom plate in a penetrating mode. A clutch lifting device used for driving the center shaft to move up and down is arranged on the rack. A main wheel assembly, a driving gear and a linking disc are arranged on the center shaft. A ring support is arranged on one side of the rack. The lower end of the ring support is fixedly connected with the bottom plate. An auxiliary wheel assembly which can rotate horizontally is arranged in the ring support, and a transmission belt is connected between the auxiliary wheel assembly and the linking disc. According to the ring type mosquito net lifting device, a main rope wheel and an auxiliary rope wheel are located on similar height planes and close to the ceiling plane, so that the probability of friction disturbance between a pulling rope and the main wheel assembly as well as between the pulling rope and the auxiliary wheel assembly can be effectively lowered, overall operation is smoother, flat design of the overall structure of the lifting device is facilitated, and dismounting and cleaning convenience and using safety are improved; and the 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 for hanging attachments, in particular to a ring-type mosquito net 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 us...
