Embodiment Construction

[0020] The invention provides a stepless rotation positioning device for use with a display device to facilitate the rotation of the display device and provide stable support at the same time. The stepless rotation device of the present invention can be well applied to home appliance display devices such as televisions, etc. However, in different embodiments, the stepless rotation positioning device of the present invention can also be applied to personal computer screens or other heavy displays device. In addition, the stepless rotation positioning device of the present invention can also be used in cooperation with other devices that need to provide rotation support.

[0021] Figure 2a Shown is a preferred embodiment of the stepless rotary positioning device of the present invention. Such as Figure 2a As shown in the sectional view, the stepless rotation positioning device includes a base 200 , a rotating shaft 300 and a positive force providing device 400 . The base 200...

Abstract

A stepless rotation positioning device can facilitate the rotation of a display device while providing a stable support. The stepless rotary positioning device includes a base, a rotating shaft and a positive force providing device. The base includes a shell and a base, and the rotating shaft includes a force end and a friction seat. The housing has a first friction surface corresponding to the second friction surface formed on the upper surface of the friction seat of the rotating shaft. The friction seat is rotatably accommodated in the housing and can move axially. The positive force providing device is arranged between the friction seat and the base, and provides a positive force to compress the friction seat along the axial direction, so that the second friction surface abuts against the first friction surface.

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...
