Description

Technical Field

[0001] The utility model relates to the technical field of projector brackets, and particularly relates to a ceiling projection flipping mechanism. Background Art

[0002] A projector, also known as a projection machine, is a device that can project images or videos onto a screen and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Projectors are 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] Generally, projectors are fixed on the ceiling. After installation, the position of the screen is adjusted. Once everything is ready, they can be used without adjustment. This installation situation is suitable for fixed places such as classrooms. Once there are situations where the screen is not fixed or the projector needs to be replaced, a new bracket mechanism needs to be prepared, resulting in high costs. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a ceiling projection flipping mechanism, which has a simple structure, can adjust the position between two clamps according to the size of the projector while being fixed on the ceiling, and can be flipped at an angle after fixation, with good use effects.

[0005] To solve the above technical problem, the utility model provides a ceiling projection flipping mechanism, which includes a mounting plate. A moving track is arranged on the mounting plate. A fixed plate and a moving plate are arranged on the moving track. A left clamping arm is arranged on the fixed plate. A left clamp is connected to the left clamping arm through a left rotating shaft. A right clamping arm is arranged on the moving plate. A rotating motor is arranged on one side of the right clamping arm. A right rotating shaft is arranged at the output end of the rotating motor. A right clamp is arranged on the right rotating shaft. A positioning plate is arranged on the side of the moving track. A moving cylinder is arranged on the positioning plate. The output end of the moving cylinder is connected to the moving plate through a connecting plate.

[0006] Further, the left clamping arm and the right clamping arm are symmetrically arranged, and positioning pins are arranged at the corresponding ports.

[0007] Further, a synchronous shaft seat is arranged on the left clamping arm, a synchronous sleeve is arranged at the corresponding position of the right clamping arm, and a synchronous rod is arranged between the synchronous shaft seat and the synchronous sleeve.

[0008] Further, a motor seat is arranged on the side of the right clamping arm, a reinforcing plate is arranged on the motor seat, and the rotating motor is fixed on the motor seat.

[0009] Further, a commutator is arranged on one side of the rotating motor, and the commutator is connected to the right rotating shaft.

[0010] Further, a limit seat is arranged between the moving plate and the fixed plate, and the limit seat is fixed on the mounting plate.

[0011] Further, a buffer seat is arranged on the mounting plate outside the moving plate and the fixed plate.

[0012] The beneficial effects of the present utility model: When in use, first adjust the distance between the left clamping arm and the right clamping arm according to the size of the projector. The position of the fixed plate remains unchanged. Start the moving cylinder, and the moving cylinder drives the connecting plate to move, thereby driving the moving plate to move on the moving track, changing the position of the right clamping arm, and thus adjusting the distance between the left clamping arm and the right clamping arm. After the adjustment is completed, fix the projector between the left clamping arm and the right clamping arm, and then fix the whole device on the ceiling through the mounting plate. When the angle needs to be adjusted, start the rotating motor, and the rotating motor drives the right clamping arm to rotate through the right rotating shaft. Since both sides of the projector are fixed by the right clamping arm and the left clamping arm, the left clamping arm will also rotate along the left rotating shaft, thereby driving the projector to rotate and adjust the angle. The structure is simple. After being fixed on the ceiling, the position between the two clamps can be adjusted according to the size of the projector, and at the same time, the angle can be flipped after the fixing is completed, and the use effect is good.

[0022] During use, first, the distance between the left clamping arm 5 and the right clamping arm 8 is adjusted according to the size of the projector. The position of the fixing plate 3 remains unchanged. The moving cylinder 13 is started, and the moving cylinder 13 drives the connecting plate 14 to move, thereby driving the moving plate 4 to move on the moving track 2, changing the position of the right clamping arm 8, and thus adjusting the distance between the left clamping arm 5 and the right clamping arm 8.
