[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 computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. There are different types of projectors, such as CRT, LCD, and DLP, depending on the working mode. Projectors need to be used with mounting brackets when in use.

[0003] In the prior art, projectors are mostly placed on a desktop or fixed on the roof through a mounting bracket. When installing the bracket, it is necessary to match the threaded holes on the surface of the bracket with the threaded holes on the surface of the projector, and then fix the four corners of the bracket in turn with screws. The installation takes a lot of time. Therefore, we propose a projector mounting bracket to solve the above problem. Utility Model Content

[0022] Further, see Figure 3 It can be known that the top of the load-bearing support cross bar 1 is fixedly connected with a rectangular sleeve 2, and a second threaded rod 12 is inserted inside the rectangular sleeve 2, and a telescopic extension rod 3 is sleeved on the surface of the second threaded rod 12. The inner wall of the telescopic extension rod 3 is provided with an internal thread. During use, the internal and external threads are used in combination to facilitate the up and down movement and height adjustment.

[0023] Further, see Figure 2 It can be known that the bottom end surface of the second threaded rod 12 is sleeved with a transmission gear 13, and the surface of the transmission gear 13 is meshed with the first threaded rod 4. During use, the first threaded rod 4 can play a self-locking function after the adjustment is completed through the meshing action between the threads during the process of adjusting the transmission gear 13.

[0024] Further, see Figure 3 and Figure 4 It can be known that the front side of the rectangular sleeve 2 is fixedly connected with a limit bearing 5, and the first threaded rod 4 is connected to the rectangular sleeve 2 through the limit bearing 5. During use, the limit bearing 5 can support the first threaded rod 4.

[0025] Further, see Figure 2It can be known that the surface of the movable rod 11 is provided with opposite external threads from the center to both ends, and the threaded sleeve 16 is connected to the movable rod 11 by threaded sliding. During use, the movable rod 11 is used to facilitate the movement of the two sets of threaded sleeves 16, and then the two sets of clamping and fixing rods 9 are driven together through the hinged push rod 10 to install the projector.

[0026] Further, see Figure 2 It can be seen that two groups of clamping and fixing rods 9 are provided, and anti-slip strips are fixedly installed on the symmetrical surfaces of the two groups of clamping and fixing rods 9.

[0028] After the installation is completed, the staff manually rotates the movable rod 11 to rotate, and the rotation of the movable rod 11 drives the threaded sleeve 16 to move. The movement of the threaded sleeve 16 drives the movable block 7 to move inside the rectangular frame 6 through the hinged push rod 10, which makes it easier to drive the clamping and fixing rod 9 to move closer. The projector is fixedly installed by clamping the fixing rod 9, and the operation is completed. The above is the entire working principle of the utility model.
