Abstract

A stepless rotational and positioning device is provided, which facilitates the rotation of a display and simultaneously provides stable support. The stepless rotational and positioning device comprises a pedestal, a rotary shaft and a positive force supplier. The pedestal comprises a shell and a base frame and the rotary shaft comprises a stress terminal and a frictional force seat, wherein the shell comprises at least one first friction surface which is arranged in correspondence to a second friction surface formed by the upper surface of the frictional force seat of the rotary shaft; the frictional force seat is rotatably equipped and contained inside the shell and adapted to the axial movement. The positive force supplier is equipped between the frictional force seat and the base frame and adapted to provide a positive force to axially compress the frictional force seat, so as to allow the contact between the first and the second friction surfaces.

Description

technical field [0001] The invention relates to a stepless rotation positioning device and a display device using the rotation positioning device; specifically, the present invention relates to a stepless rotation positioning device for use with a display device. Background technique [0002] The advancement of display device technology has met various needs in people's information life, and its applications are very extensive, ranging from small personal electronic products to computer screens, home appliances, and advertising billboards. The close connection between display devices and human life can be seen everywhere. . [0003] At present, commonly used positioning devices for display devices of home appliances can be roughly divided into two types: fixed type and rotary type. The former is either integrally formed with the home appliance display device, or installed around the bottom of the home appliance display device. Although it can provide stable support, it cann...
