Spiral supporting device, projector and adjusting method of spiral supporting device

Abstract

The invention provides a spiral supporting device, a projector and an adjusting method of the spiral supporting device. The spiral supporting device comprises a fixed support, a spiral support and a first damping pad and is characterized in that the fixed support is equipped with a first support arm which is provided with a shaft hole; the spiral support is provided with a second support arm which is equipped with a rotating shaft; the rotating shaft is stuck in the shaft hole; the first support aim is also provided with a fixed hole; the second support arm is equipped with an arc hole which is corresponding to the fixed hole; a fastener passes through the arc hole and the fixed hole to connect the first support arm and the second support arm; and the first damping pad is positioned between the first support arm and the second support arm. The hinge effect can be reached through the rotating shaft of the spiral support and the shaft hole on the fixed support with the combination of the first damping pad, thus effectively simplifying the structure of the spiral support device and reducing the manufacturing cost of the spiral support device.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a rotary support device, a projector and a method for adjusting the rotary support device. Background technique [0002] At present, with the continuous advancement of science and technology, projectors are widely used in people's daily life. Depending on the installation, the projector can be placed directly on a table, or mounted on a wall or ceiling. In order to adjust the projection angle of the projector conveniently, the existing technology usually uses a rotating support base to support and fix the projector, and the rotating support base usually uses hinge technology to realize the rotation and adjustment of the angle of the projector. The hinge of the rotating support base in the prior art is usually a The individual parts are supplied by the hinge manufacturer as a complete set. The structure of the hinge is complicated, the debugging method is complicated, and the operation is ...
