A three-point support adjusting mechanism for digital cinema projector

Abstract

The invention discloses a three-point type supporting regulating mechanism for a digital movie projector. The three-point type supporting regulating mechanism at least comprises a panel bracket, a set of center supporting assembly and a group of regulating mechanism, wherein the panel bracket is used for installing the digital movie projector; at least three projector fixing assemblies are arranged at the edge and corner positions of the panel bracket; the center supporting assembly is arranged on the panel bracket and is positioned at the center region of the panel bracket; the regulating mechanism is arranged at the side end of the panel bracket; the regulating mechanism comprises a set of center horizontal position regulating assembly and a set of vertical regulating assemblies; the center horizontal position regulating assembly is used for regulating a horizontal deflection angle of the projector; the vertical regulating assemblies are assembled in pairs and are used for regulating a front-and-rear elevation angle and a left-and-right torsion angle of the projector. The three-point type supporting regulating mechanism can be stably installed, can regulate the horizontal, vertical and torsion positions of the projector so as to ensure the field requirements and does not need to use an additional power assisting device.

Description

technical field [0001] The invention relates to a digital movie projector mounting bracket system, in particular to a three-point support adjustment mechanism for a digital movie projector with multi-directional adjustment functions. Background technique [0002] Usually, traditional cinema digital cinema projectors place the projector feet on the base or simple support plane, and limit the position of the projector through corresponding grooves. [0003] Disadvantages of existing base support systems: [0004] 1. For the support system of digital cinema projectors, the feet of the projector and the base are not fixedly connected, and the stability is poor. It is easy to cause position drift due to machine vibration or accidental collision, resulting in poor coincidence of the two-machine images projected on the screen, which affects projection quality; [0005] 2. System adjustment requires the use of large wrenches or sockets to adjust the projector feet or base feet. Th...

Problems solved by technology

[0004] 1. For the support system of digital cinema projectors, the feet of the projector and the base are not fixedly connected, and the stability is poor. It is easy to cause position drift due to machine vibration or accidental collision, resulting in poor coincidence of the two-machine images projected on the screen, which affects projection quality;

[0005] 2. System adjustment requires the use of large wrenches or sockets to adjust the projector feet or base feet. The operating position is not ideal, requiring a large torque, and the screen cannot be observed at the same time;

[0006] 3. The system adjustment cannot take into account multiple directions at the same time, and it is easy to cause mutual interference, which requires repeated adjustments to achieve
