Embodiment 1
[0022] Embodiment one, with reference to Figure 1-3 , a projector support for enterprise management teaching, including a fixed plate 5 and an outer shell 11, electromagnetic plates 6 are symmetrically arranged on both sides of the bottom of the fixed plate 5, a fixed arm 3 is welded on the top of the fixed plate 5, and the center of the top of the fixed arm 3 passes through The connecting block is welded with the mounting plate 1, and a biaxial motor 7 is fixedly installed inside the fixed arm 3 and in the middle of the upper surface of the fixed plate 5. The biaxial motor 7 can synchronously control the two reels 4 to run, so that the steel The rope 8 is wound, and the two ends of the biaxial motor 7 are connected to the transmission shaft 2 through the output shaft transmission, the transmission shaft 2 is parallel to the upper surface of the fixed plate 5, and the two transmission shafts 2 are welded with the winding wheel 4, and Steel ropes 8 are wound around the two ree...
Embodiment 2
[0023] Embodiment two, refer to figure 1 with Figure 4 One of the two rotating shafts 10 is welded with a gear 19, and the bottom of the gear 19 is meshed with a rack 20, one end of the rack 20 is connected to the XTL100 electric telescopic rod 21, and the XTL100 electric telescopic rod 21 is bolted to the On the inner surface wall of one side of the outer casing 11, the rack 20 is parallel to the horizontal end surface of the outer casing 11, and the bottom of the rack 20 is slidingly connected with the inner surface wall at the bottom of the outer casing 11, and the rack 20 is pushed to slide by the XTL100 electric telescopic rod 21 , so that the gear 19 rotates, and the rotation of the gear 19 drives the rotating shaft 10 to rotate, so that the inner casing 12 and its internal projector rotate together to achieve the purpose of adjusting the projection angle, and through this structure, the projector can be fixed at any adjustment In terms of angle, there will be no defle...
Embodiment 3
[0024] Embodiment three, refer to Figure 1-2 An air pump 13 is embedded in the center of the bottom of the inner housing 12, and the air pump 13 communicates with the inner cavity of the air bag layer 14 through the air intake pipe 17, and a gas release valve 16 is also provided on the outer wall of the bottom of the inner housing 12, and the gas release valve 16 The exhaust pipe 15 communicates with the air bag layer 14, and the connection between the air intake pipe 17 and the air bag layer 14 is also provided with a one-way air valve 18. The one-way air valve 18 is used to ensure the one-way flow of air, and works through the air pump 13. External air enters into the airbag layer 14. As the gas increases, the air pressure gradually increases, and the airbag layer 14 expands and becomes larger. The edge of the projector can be clamped and fixed without manual clamping. The structure is simple, easy to operate, and fixed The effect is stable and reliable, and the installatio...
