[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing conference room projector is hung on the ceiling, and since the position of the projector is fixed, the height and angle of the projector cannot be adjusted, thereby reducing the practicality of the device. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a multimedia device for a conference room.
[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a multimedia device for a conference room, comprising a top plate, support blocks are symmetrically installed on the bottom surface of the top plate, screws are arranged on the side walls of two support blocks that are close to each other and rotate together, a slider is threadedly connected on the outer wall of the screw, the slider slides relative to the top plate, a motor is fixedly arranged on the side wall of one of the support blocks, the output shaft end of the motor is fixed to the screw, a mounting rod is fixedly arranged on the bottom surface of the slider, and a projector is installed on the bottom surface of the mounting rod.
[0006] By adopting the above technical solution, when the staff needs to use the projector, the staff needs to turn on the projector, and then the projector is projected onto the wall. Then, when the staff needs to adjust the projector, the staff needs to start the motor, and then the output shaft of the motor rotates, so that the screw rod rotates synchronously with the motor output shaft under the action of the motor output shaft, and then the slider slides under the action of the screw rod, so that the installation rod and the projector move under the action of the slider, and then the position of the projector is adjusted, thereby improving the practicality of the device.
[0007] Furthermore, a slide groove is provided on the bottom surface of the mounting rod, a slide rod is slidably arranged in the slide groove, and the bottom surface of the slide rod is connected to the upper surface of the projector.
[0008] By adopting the above technical solution, when the staff needs to adjust the height of the projector, the staff needs to slide the sliding bar upward or downward, and then the projector moves upward or downward under the action of the sliding bar, thereby adjusting the height of the projector, thereby improving the practicality of the device.
[0009] Furthermore, fixing grooves are symmetrically provided on the outer wall of the sliding rod, and a plurality of blocking grooves are symmetrically provided through the outer wall of the mounting rod, and the plurality of blocking grooves are distributed in an array, and fixing rods are slidably provided in both fixing grooves, and a first spring is fixedly provided on the side wall of the fixing rod, and the other end of the first spring is fixedly provided on the inner wall of the fixing groove, and the fixing rod is slidably connected to the blocking groove.

[0031] When the staff needs to use the projector 16, the staff needs to turn on the projector 16, and then project the projector 16 onto the wall. Then, when the staff needs to adjust the projector 16, the staff needs to start the motor 14, and then the output shaft of the motor 14 rotates, so that the screw 12 rotates synchronously with the output shaft of the motor 14 under the action of the output shaft of the motor 14, and then the slider 13 slides under the action of the screw 12, so that the installation rod 15 and the projector 16 move under the action of the slider 13, and then the position of the projector 16 is adjusted, thereby improving the practicality of the device.
[0032] The bottom surface of the mounting rod 15 is provided with a slide groove 2. The slide rod 3 is a round rod structure, whose axis coincides with the axis of the mounting rod 15. The slide rod 3 is slidably arranged in the slide groove 2, and the bottom surface of the slide rod 3 is connected to the upper surface of the projector 16.
[0033] When the staff needs to adjust the height of the projector 16, the staff needs to slide the slide bar 3 upward or downward, so that the projector 16 moves upward or downward under the action of the slide bar 3, thereby adjusting the height of the projector 16, thereby improving the practicality of the device.
[0034] The outer wall of the slide bar 3 is symmetrically provided with fixing grooves 21, and the outer wall of the mounting rod 15 is symmetrically provided with a plurality of blocking grooves 22, which are arranged in an array.

Then, when the staff needs to adjust the projector 16, the staff needs to start the motor 14, so that the output shaft of the motor 14 rotates, so that the screw 12 rotates synchronously with the output shaft of the motor 14 under the action of the output shaft of the motor 14, and then the slider 13 slides under the action of the screw 12, so that the mounting rod 15 and the projector 16 move under the action of the slider 13, so that the position of the projector 16 is adjusted. When the staff needs to adjust the height of the projector 16, the staff needs to slide the slider 3 upward or downward, so that the projector 16 moves upward or downward under the action of the slider 3, so as to adjust the height of the projector 16. When the staff needs to adjust the angle of the projector 16, the staff needs to slide the movable block 51 into the movable groove 23. Then, the staff rotates the rotating block 5, so that the projector 16 rotates under the action of the rotating block 5, so as to adjust the angle of the projector 16.
