Description

Technical Field

[0001] The utility model belongs to the technical field of multimedia teaching, and in particular relates to a mounting bracket for multimedia teaching projection equipment. Background Art

[0002] Multimedia teaching refers to a teaching method in which teachers use multimedia technology, such as computers, projectors, audio equipment, etc., combined with multiple media forms such as text, pictures, audio and video, to present and deliver teaching content during the teaching process. This teaching method can enrich teaching methods, increase students' interest and participation in learning, and thus improve teaching effectiveness.

[0003] In the process of multimedia teaching, a projector will be used. The projector can project images and videos on a computer, notebook or other device onto a screen or wall, so as to display the teaching content over a large area. The positions of the projector and the screen are fixed, which reduces the risk of students touching the equipment and the possibility of damage or safety accidents caused by improper operation. The projector will be installed at the bottom of the ceiling using a mounting bracket to prevent the projector from being hit. During long-term use of the projector, dust may be adsorbed on the lens surface, causing blurred projection images. The projector needs to be cleaned and maintained. When cleaning and maintaining the projector, the projector needs to be disassembled. After cleaning and maintaining the projector, the projector still needs to be installed and fixed. During the disassembly and installation process, workers need to use ladder tools to disassemble and install at a high place. Workers working at a high place may fall from the ladder, posing a safety hazard. The problem with the above technology is that when disassembling and installing the projector, workers need to use ladders to disassemble and install at a high place.

[0025] The working principle of this utility model:

[0026] When the projector 3 needs to be maintained, the dual-axis motor 201 is started to reverse, and the output ends on the left and right sides of the dual-axis motor 201 drive the two winding shafts 202 to rotate. During the rotation of the two winding shafts 202, the two connecting ropes 203 are unwound, and the mounting plate 204 moves downward. During the movement of the mounting plate 204, the supporting plate 603 is driven to move downward through the connecting bolts 601. During the movement of the supporting plate 603, the projector 3 is driven to move downward. After the projector 3 moves to a lower position, the connecting bolts 601 are reversed, and the connecting bolts 603 are connected. During the reversal of 01, the support plate 603 is driven to move downward, and the projector 3 is driven to move downward, so that the top of the projector 3 is out of contact with the mounting plate 204, and the front clamping plate 703 is pulled forward, and the front clamping plate 703 drives the front clamping tension spring 701 to deform, and the front clamping plate 703 is out of contact with the projector 3, so that the projector 3 is taken out and maintained. After the maintenance of the projector 3 is completed, the projector 3 is placed between the two clamping plates 703, and the clamping tension spring 701 rebounds and drives the two clamping plates 703 to clamp and fix the projector 3. The connecting bolt 601 is fixed, and the connecting bolt 601 is rotated. During the rotation of the connecting bolt 601, the supporting plate 603 is driven to move upward. During the movement of the supporting plate 603, the projector 3 is driven to move upward. The top of the projector 3 contacts the bottom of the mounting plate 204. The projector 3 is clamped and fixed by the supporting plate 603 and the mounting plate 204, so that the projector 3 remains stable. The dual-axis motor 201 is started, and the two output ends of the dual-axis motor 201 drive the two winding shafts 202 to rotate, and the two winding shafts 202 wind up the two connecting ropes 203. The two connecting ropes 203 drive the mounting plate 204 to move upward. During the movement of the mounting plate 204, the projector 3 and the two sockets 9 are driven to move upward. The two sockets 9 move upward and are sleeved on the surfaces of the two plug rods 8. The moving direction of the mounting plate 204 is limited by the two plug rods 8, thereby preventing the mounting plate 204 from shifting. The top of the mounting plate 204 contacts the bottom of the two limit blocks 5. The position of the top of the mounting plate 204 is limited by the two limit blocks 5, so that the mounting plate 204 remains stable, thereby keeping the projector 3 stable.
