Projection support

Abstract

The invention discloses a projection support. The support comprises a suspender assembly provided with a first mounting structure, the suspender assembly is provided with a fixing frame, the fixing frame is movably pivoted with a first swing frame, and a first lead screw and a first nut are arranged between the first swing frame and the fixing frame. The first swing frame is movably pivoted with a second swing frame, and a second lead screw and a second nut are arranged between the first swing frame and the second swing frame. The second swing frame is connected with a mounting plate for mounting projection equipment. According to the projection support of the structure, the first lead screw is rotated, the first nut moves relative to the first lead screw to drive the first swing frame to swing up and down relative to the fixing frame, the second lead screw is rotated, the second nut moves relative to the second lead screw to drive the second swing frame to swing left and right relative to the first swing frame, the first lead screw and the second lead screw can only rotate without axial movement so that the swing angle of the projection equipment on the mounting plate in the left-right direction and the front-back direction can be accurately adjusted, and the adjustment is simple and quick.

Description

technical field [0001] The invention relates to a support for projection. Background technique [0002] In the prior art, most of the projection equipment is hung on the indoor ceiling by brackets. In order to adjust the projection direction of the projection equipment, it is necessary to drive the projection equipment to produce a certain displacement and swing relative to the projection bracket during the installation and debugging process. , and then fix the position of the projection device, especially the adjustment of the angle of the projection device is more important, but the adjustment mechanism of the current bracket is difficult to adjust the angle of the projection device's up and down swing and left and right swing, the adjustment accuracy is low, and the adjustment method is very inconvenient.

[0002] In the prior art, most of the projection equipment is hung on the indoor ceiling by brackets. In order to adjust the projection direction of the projection equipment, it is necessary to drive the projection equipment to produce a certain displacement and swing relative to the projection bracket during the installation and debugging process. , and then fix the position of the projection device, especially the adjustment of the angle of the projection device is more important, but the adjustment mechanism of the current bracket is difficult to adjust the angle of the projection device's up and down swing and left and right swing, the adjustment accuracy is low, and the adjustment method is very inconvenient

[0003] In addition, the installation between the bracket and the projection equipment is generally connected by bolt components. For different types of projection equipment, the positions of the installation holes are different. The current projection bracket cannot be adapted to install projection equipment of different sizes.
