Projection equipment carrying out angle adjustment for film and television media

Abstract

The invention discloses projection equipment carrying out angle adjustment for film and television media. The projection equipment comprises a bearing bottom plate, an angle adjusting assembly, a clamping and fixing assembly, a projector and a mounting assembly, the angle adjusting assembly is arranged at the top end of the bearing bottom plate and comprises a control structure and a traction structure, the control structure comprises two supporting plates, two moving plates are arranged between the two supporting plates, the traction structure comprises two moving rods, rod arms of the two moving rods are provided with connecting blocks in a sleeved mode, traction rods are arranged at the top ends of the two connecting blocks, the clamping and fixing assembly is arranged at the top end of a protective cover, the projector is arranged at the top end of the clamping and fixing assembly; and the mounting assembly is arranged at the top end of the protective cover. The projection equipment has the beneficial effects that the angle adjusting assembly is arranged and is arranged on the bearing bottom plate, and projection angle calibration of the projector is carried out through the angle adjusting assembly, so that projection errors are avoided, and the trouble of repeated disassembly, assembly and calibration is omitted.

Description

technical field [0001] The invention relates to a projection device, in particular to a projection device for film and television media that performs angle adjustment, and belongs to the technical field of film and television media equipment. Background technique [0002] With the continuous development and promotion of film and television media technology, and in order to facilitate the promotion of film and television media, some projection equipment will be used in many places, so that the use of projection equipment and light curtain can achieve better visual effects. [0003] Existing projection equipment uses some simple fixing frames to fix the projector. During the fixation, a series of data measurements must be carried out, including the projection angle between the projector and the light curtain, the projection position and the fixed height of the projector. etc. It is easier to grasp the fixed height of the projector, but a series of measurements are required for...

AI Technical Summary

Problems solved by technology

[0003] Existing projection equipment uses some simple fixing frames to fix the projector. During the fixation, a series of data measurements must be carried out, including the projection angle between the projector and the light curtain, the projection position and the fixed height of the projector. etc. It is easier to grasp the fixed height of the projector, but a series of measurements are required for the projection angle and projection position, and then the projector is fixed and installed according to the calculated data. Once these positions are fixed, they cannot be fixed. It is easy to change, otherwise it will affect the projection effect, but in the actual installation and use process, it will inevitably cause a certain data deviation, which makes the installation of the entire projection equipment extremely cumbersome, and once it is fixed, it is found that the projection angle deviation occurs , and re-disassemble the correction position, so that the whole process will take a long time. At the same time, the continuous disassembly and assembly will also damage the projection equipment to a certain extent. Therefore, a projection equipment that can adjust the angle is needed. The projection angle can be adjusted after installation
