The invention relates to a lifting device, in particular to a lifting device for a displayer. The lifting device comprises a support of a hollow tubular structure, a lifting piece slidably inserted into the support, a concentration piece, a spring adjustment mechanism and a rolling piece, wherein one end of the concentration piece is connected with the lifting piece, the other end of the concentration piece is connected with the support, the spring adjustment mechanism is arranged between the support and the lifting piece and used for adjusting the friction force between the support and the lifting piece, and the rolling piece is arranged in the support and enables the lifting piece to roll along the surface of the rolling piece when doing lifting motion. According to the lifting device for the displayer, the rolling piece is adopted as a contact body between the support and the lifting piece, partial sliding friction is changed into rolling friction, the whole lifting process of the lifting device can be kept smooth, lifting is stable, the service life of the lifting device is prolonged to a certain degree, and the reliability of the lifting device is improved to a certain degree as well; and by arranging the spring adjustment mechanism between the support and the lifting piece, the force value difference of the upper segment and the lower segment can be balanced, and hand feeling is improved.
Description
technical field [0001] The invention relates to a lifting device, in particular to a display lifting device. Background technique [0002] In order to enable the position of the display to be adjusted quickly according to different users, the position and height of the display are suitable for viewing needs, and a supporting lifting device is required for support. The quality of the lifting device directly affects the quality of the whole machine. A reasonable lifting device can not only provide users with better and more comfortable conditions of use, but also minimize the size and save space. [0003] At present, there are many display lifting devices on the market, which adopt a pull-out structure, and support the weight of the display through an internal constant force spring. [0004] However, most of the current pull-type display lifting devices adopt the way of sliding and pulling up and down, which has a large friction force, and the operation is not smooth enough i...
