Multidirectional adjustable projection device

Abstract

The invention discloses a multidirectional adjustable projection device. The multidirectional adjustable projection device comprises a groove; a sliding rail and a fixed plate are fixedly mounted at the top of the groove; a first motor is mounted on the front side of the fixed plate; an output shaft of the first motor is fixedly provided with a first connecting rod; the sliding rail is slidably connected with a sliding block; the bottom of the sliding block is fixedly connected with a push rod motor; an output shaft of the push rod motor is fixedly connected with a telescopic rod; the top of the telescopic rod is fixedly connected with a top plate; the bottom of the top plate is fixedly connected with a back plate; a second motor is fixedly connected to the left side of the back plate; andan output shaft of the second motor is connected with a second rotating shaft. According to the multidirectional adjustable projection device, the first motor is rotated, the sliding block is drivento slide on the sliding rail under the action of the connecting rod, the projecting device is adjusted front and back, under the action of the push rod motor and the telescopic rod, the projection device is adjusted up and down, through frictional force transmission of a belt wheel and a belt, the projection device is adjusted left and right, and the projection device is adjusted in the three directions independently, so that the position of the projection device is adjustable freely within a reasonable range, and the requirements of use are met.

Description

technical field [0001] The invention relates to an electronic product, in particular to a multi-directional adjustable projection device. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are currently widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] At present, the projection devices on the market occupy the ground space, reducing the indoor utilization area, and most of them are fixed structures, which makes it difficult to adjust the projector to a suitable position and has low adaptability. [0004] In order to solve the problem that the projection device takes up space on the ground and is difficult to adjust, a Chinese pat...

Problems solved by technology

[0003] At present, the projection devices on the market occupy the ground space, reducing the indoor utilization area, and most of them are fixed structures, making it difficult to adjust the projector to a suitable position, and the adaptability is low

[0004] In order to solve the problem that the projection device takes up space on the ground and is difficult to adjust, a Chinese patent (CN207716042U) discloses a demonstration device for projection teaching. Adjust the position of the projector, but the up and down adjustment and front and rear adjustment of the device are controlled by the same telescopic rod, which cannot be carried out independently, so there are many dead angles in the position, which cannot meet the use requirements
