[0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of blind holes and observe the surface of parts. With the continuous development and progress of electronic information technology, projectors are used more and more widely. They can be connected to computers, VCD, DVD, BD, game consoles, DV, etc. through different interfaces to play corresponding video signals.

[0003] Existing ceiling-mounted projectors, that is, projectors installed on the top of the wall, can not only save desktop space, but also are more convenient to use. However, after the existing ceiling-mounted projectors are installed, it is inconvenient to adjust the angle, which affects their use; in addition, most ceiling-mounted projectors are fixed on the top of the wall, which is inconvenient to install and disassemble, and they do not have good protection and are easily scratched by the outside; at the same time, when the ceiling-mounted projector is working continuously, its internal heat will accumulate and heat up, thereby affecting its service life. In summary, the existing ceiling-mounted projectors still have the following problems:

[0004] 1. After the ceiling-mounted projector is installed, it is inconvenient to adjust its angle; 2. Most ceiling-mounted projectors are fixed on the wall, which makes it inconvenient to install and disassemble; 3. When the ceiling-mounted projector works continuously, heat will accumulate inside and the temperature will rise, affecting its service life. Utility Model Content

[0025] The adjustment device 2 includes a fixed seat 20, a connecting column 22 is fixedly installed on the upper end of the fixed seat 20, a movable seat 23 is fixedly installed on the upper end of the connecting column 22, a driven gear 25 is fixedly installed on the outer surface of the connecting column 22, and a driving gear 24 is meshed and connected to the rear end of the driven gear 25, and a motor 21 is installed on the upper end of the driving gear 24. The motor 21 is fixedly installed at the rear of the upper end of the mounting frame 6, and the movable seat 23 is movably installed at the lower end of the mounting frame 6. The fixed seat 20 is fixedly installed at the middle of the upper end of the mounting box body 1. The driving gear 24 on it is driven by the motor 21, and the driving gear 24 will drive the driven gear 25 on the connecting column 22 to rotate. When the connecting column 22 rotates, it will drive the lower end of the mounting box body 1 and the projector 5 therein to rotate, so as to adjust the angle of the projector 5.

[0026] The clamping device 3 includes two clamping plates 30, and the clamping plates 30 are provided with a plurality of clamping springs 31 installed at the opposite ends of the two clamping plates 30. The two clamping plates 30 are respectively installed on the left inner wall and the right inner wall of the installation box body 1 through the clamping springs 31. A vent 34 is provided at the right rear end of the installation box body 1. A group of card slots 32 are provided at the front of the upper end and the front of the lower inner wall of the installation box body 1. A clamping frame 33 is installed at the upper ends of the two groups of card slots 32; the clamping frame 33 is U-shaped. When the projector 5 is pushed between the two clamping plates 30, the clamping springs 31 on the clamping plates 30 are contracted by force, thereby clamping the projector 5 in the installation box body 1. When the projector 5 is pushed in, the clamping frame 33 is inserted into the card slot 32, thereby limiting the position of the projector 5 to prevent it from sliding out after installation. When the projector 5 needs to be disassembled, the clamping frame 33 only needs to be pulled out.

[0028] It should be noted that the utility model is a ceiling-mounted projector with adjustable projector angle. First, the projector 5 is pushed between the two clamping plates 30 on the clamping device 3. At this time, the clamping spring 31 on the clamping plate 30 is contracted by force, thereby clamping the projector 5 in the installation box body 1. After the projector 5 is pushed in, the clamping frame 33 is inserted into the clamping groove 32, thereby limiting the projector 5 to prevent it from sliding out after installation. When the projector 5 needs to be disassembled, it is only necessary to pull out the clamping frame 33, thereby facilitating the installation and disassembly of the projector 5. After the projector 5 is installed, the mounting frame 6 is then installed on the top of the wall. At this time, the motor 21 on the adjusting device 2 is used to adjust the projector 5. The driving gear 24 thereon drives the driven gear 24 to rotate. The driving gear 24 thereby drives the driven gear 25 on the connecting column 22 to rotate. Since the movable seat 23 is movably installed in the mounting frame 6, and the fixed seat 20 is fixedly installed on the mounting box body 1, when the connecting column 22 rotates, it will drive the mounting box body 1 at the lower end and the projector 5 therein to rotate, thereby adjusting the angle of the projector 5. In addition, when the projector 5 works continuously, causing the heat accumulated therein to rise, the fan 40 on the heat dissipation device 4 rotates to blow air, and the wind is then blown into the mounting box body 1 through the vent 34, thereby accelerating the air circulation speed on the outer surface of the projector 5 to dissipate heat from the projector 5.
