A two-way interactive projector with reversing function

Abstract

The invention relates to the technical field of projectors, and discloses a two-way interactive projector with a reversing function, comprising a base, a vertical cylinder is fixedly installed at the center of the top of the base, and a fixed bearing is fixedly installed on the inner wall of the vertical cylinder , a rotating shaft is fixedly installed on the inner wall of the fixed bearing, a connecting plate is fixedly installed on the top of the rotating shaft, and the two ends of the connecting plate are respectively provided with a first projection device and a second projection device, the first projection device and the Each of the second projection devices includes a fixed plate, side ears, a rotating column, an outer cylinder and a projector. The top of the rotating shaft is provided with a connecting plate, and both ends of the connecting plate are provided with projectors. Both projectors can project pictures. In actual use, the two projectors can project different pictures respectively, and the use effect is better. The present invention has novel design and simple structure, and has the advantages of having two projectors, capable of adjusting the projection direction, convenient adjustment of the height of the projector, and no trapezoidal picture.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a bidirectional interactive projector with a reversing function. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen, and is widely used in homes, offices, and schools. For example, the Chinese patent publication number is: CN106051388B, which discloses a remotely controlled intelligent projector, including a body, a lens, a cooling fan, a network interface, a storage interface and a power interface, a support mechanism and a power button; The supporting mechanism includes a horizontally arranged drive assembly and a drive assembly that is drive-connected to the drive assembly. The drive assembly includes a drive motor, an eccentric wheel and an eccentric shaft. Displacement, so that the connecting rod pulls the guide slider to slide inside the guide rail, and realizes the height adjustment of the s...

Problems solved by technology

[0004] 1. Although the above-mentioned projector can adjust the height and angle of the projector, its structure is not only complicated, but also it is easy to make an elevation angle between the projection direction of the lens and the projection screen when the angle is adjusted, resulting in the projection on the screen. The screen is trapezoidal, which seriously affects the visual effect;

[0005] 2. The interactive effects of the above projectors are poor, and there is only a single projector: in many cases, we need to use two projectors to project different images at the same time, such as when teaching, one projector is used to project PPT, and the other Projectors are used to project video images. If only one projector is installed, it is troublesome to switch images back and forth, and it is impossible to project at the same time; Projection direction, poor teaching effect;
