Description

Technical Field

[0001] This utility model relates to the field of projector technology, specifically to a ceiling-mounted projector with angle adjustment function. Background Technology

[0002] A ceiling-mounted projector is a projection device installed on the ceiling. It is usually fixed to the ceiling in a suspended manner, saving floor space and making space utilization more efficient. It generally has high brightness and can overcome the interference of ambient light to a certain extent. The size and clarity of its projected image depend on its own resolution and projection distance. Most ceiling-mounted projectors have keystone correction function, which is very useful when the installation angle may not be completely perpendicular to the screen. The image shape can be adjusted to maintain a rectangle through software or hardware. However, when the projection angle needs to be adjusted, it is often not flexible to project the image to the appropriate position. Adjusting the horizontal rotation and vertical tilt angle is somewhat difficult and not flexible enough. In addition, after the projector has been working at a certain angle for a period of time, dust is easy to accumulate on the lens surface, affecting the projection effect.

[0003] To address the aforementioned issues, a ceiling-mounted projector with angle adjustment function is proposed. Utility Model Content

A connecting frame 38 is fixedly connected to the upper surface of the projector body 4. A connecting rod B381 is fixedly connected to the inner wall of the connecting frame 38. The connecting rod B381 passes through the connecting block 37. When adjusting the angle of the projector body 4, the motor 31 drives the rotating shaft 32 to rotate, thereby driving the turntable 33 and the U-shaped frame 34 below it to rotate. Under the connection of the mounting plate 41 and the connecting rod A341, the horizontal angle of the projector body 4 can be adjusted. In addition, when adjusting the tilt angle, the electric telescopic rod 36 drives the connecting block 37 to move upward. The connecting rod B381 is rotatably connected to the connecting block 37. When the connecting block 37 moves upward, one end of the projector body 4 is lifted. At the same time, the connecting rod A341 rotates inside the mounting plate 41, acting as a lever fulcrum, and finally realizing the tilt angle adjustment of the lens of the projector body 4.

[0024] The air-blowing component 5 includes a side plate 51 fixedly connected to one side of the connecting block 37. A compression plate 52 is fixedly connected to the upper surface of the side plate 51. An air storage plate 53 is fixedly connected to the bottom surface of the support plate 35.

The outer side of the sealing plate 521 is in contact with the inner wall of the air storage plate 53. When the electric telescopic rod 36 retracts and drives the connecting block 37 to move upward, the compression plate 52 drives the sealing plate 521 to compress the air inside the air storage plate 53, providing power for subsequent exhaust.

[0025] An extension plate 54 is fixedly connected to one side of the U-shaped frame 34. The extension plate 54 is internally connected to the air guide groove 531. A dust removal plate 56 is fixedly connected to the upper surface of the projector body 4. An air guide hose 55 is fixedly connected between the extension plate 54 and the dust removal plate 56.

The breather valve 532 is used to balance the air pressure.

[0028] The ceiling plate 1 has threaded holes on its upper surface, and bolts 11 are installed inside the threaded holes. There are four sets of bolts 11, which are equidistantly and symmetrically arranged. The installation of the ceiling plate 1 is facilitated by the arrangement of the bolts 11.

[0029] Specifically, when adjusting the angle of the projector body 4, the motor 31 drives the rotating shaft 32 to rotate, causing the turntable 33 and U-shaped frame 34 to rotate horizontally. Under the connection of the mounting plate 41 and the connecting rod A341, the horizontal angle of the projector body 4 can be adjusted. At the same time, the electric telescopic rod 36 drives the connecting block 37 to extend and retract vertically. The connecting rod B381 is rotatably connected to the connecting block 37. When the connecting block 37 moves upward, it lifts one end of the projector body 4. The connecting rod A341 rotates inside the mounting plate 41, acting as a lever fulcrum to adjust the tilt angle of the projector body 4 lens. During the adjustment process, when the electric telescopic rod 36 retracts and drives the connecting block 37 to move upward, the squeezing plate 52 drives the sealing plate 521 to squeeze the air inside the air storage plate 53. The bulging air is discharged from the dust removal plate 56 through the dust removal plate 56, the air guide hose 55, and the extension plate 54, cleaning the dust attached to the lens surface. Finally, it achieves the purpose of facilitating the adjustment of the projector tilt angle and cleaning the dust on the lens surface.
