Bidirectional interaction projector with reversing function

Abstract

The invention relates to the technical field of projectors, and discloses a bidirectional interaction projector with a reversing function. The bidirectional interaction projector comprises a base, a vertical cylinder is fixedly mounted at the center of the top of the base, a fixed bearing is fixedly mounted on the inner wall of the vertical cylinder, and a rotating shaft is fixedly mounted on the inner wall of the fixed bearing. A connecting plate is fixedly installed at the top of the rotating shaft, a first projection device and a second projection device are arranged at the two ends of the connecting plate correspondingly, and each of the first projection device and the second projection device comprises a fixing plate, side lugs, a rotating column, an outer cylinder and a projector. The top of the rotating shaft is provided with the connecting plate, the two ends of the connecting plate are provided with the projectors, the two projectors can project pictures, in actual use, the two projectors can project different pictures correspondingly, and the using effect is better. The bidirectional interaction projector with the reversing function is novel in design and simple in structure, and has the advantages that the two projectors are arranged, the projection directions can be exchanged, the height of the projectors is convenient to adjust, and trapezoidal pictures cannot be generated.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a two-way 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 places such as homes, offices, and schools. For example, the Chinese patent announcement number is: the invention patent of CN106051388B, which discloses a remote-controlled intelligent projector, including a body, a lens, a cooling fan, a network interface, a storage interface, a power interface, a support mechanism, and a power button; The support mechanism includes a drive assembly arranged horizontally and a transmission assembly 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, realizing the height a...

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;
