Problems solved by technology

However, when using a ball and socket joint to adjust a projector, force is applied directly on the projector. It is difficult to precisely control the force, and it is not easy to make small adjustments. It often takes a lot of time, and it is still difficult to adjust to the ideal position.

Abstract

The invention discloses a bearing device, which comprises a fixed unit, a movable unit and an adjusting unit. The movable unit is movably connected with the fixed unit, and comprises a rotating component and a base component. The adjusting unit comprises a first inclination adjusting component, a second inclination adjusting component and a rotation adjusting component, the first inclination adjusting component and the second inclination adjusting component penetrate through the rotating component at an interval, can move parallel to a central shaft passing through the fixed unit and the movable unit and can be movably connected with the base component to drive the base component to swinging to an appropriate position with the central shaft as an axial center, and the rotation adjusting component is movably arranged on a base and the rotating component to drive the rotating component and the base component to synchronously rotate to an appropriate angle with the central shaft as an axial center. Due to the adjusting unit, fine tuning of the base component in three axial directions can be realized.

Description

technical field [0001] The invention relates to a carrying device, in particular to a carrying device capable of finely adjusting the rotation angle and inclination. Background technique [0002] In general meeting rooms or audio-visual rooms and other places where projectors are always available, the projectors are usually suspended from the ceiling to facilitate indoor space planning. [0003] In order to enable the lens of the projector to face the projection screen, and to enable the projected picture to be clearly displayed on the projection screen in equal proportions, the carrying device usually used to hang the projector needs to be able to rotate and swing the projector to adjust Projected screen. [0004] A common projector carrying device utilizes a ball joint located on a central bearing to adjust the rotation angle and inclination of the projector, such as disclosed in European Patent Publication EP1867911A1. However, when using ball and socket joints to adjus...
