[0032] Reference Figure 1-3 The utility model provides an embodiment: a camera device for a smart classroom that is easy to maintain, including a mounting seat 1, a fixing seat 2 is slidably connected inside the mounting seat 1, a mounting bracket 3 is fixedly connected to the front of the fixing seat 2, and a camera device body 4 is fixedly connected to the bottom of the mounting bracket 3. Card grooves 5 are provided on both sides of the inner wall of the mounting seat 1, and shafts 6 are fixedly connected to both sides of the inside of the fixing seat 2. An arc-shaped card plate 7 is movably connected to the surface of the shaft 6. Limiting rings 24 are provided on the front and rear sides of the arc-shaped card plate 7. The limiting rings 24 are fixedly connected to the surface of the shaft 6. By setting the limiting rings 24, the arc-shaped card plate 7 can be limited to prevent the arc-shaped card plate 7 from rotating during rotation. The surface of the arc-shaped card plate 7 contacts the inner wall of the card slot 5, and a push plate 8 is arranged inside the fixed seat 2. Both sides of the push plate 8 are fixedly connected to the limit plates 22. The side of the limit plate 22 away from the push plate 8 contacts the inner wall of the fixed seat 2. By setting the limit plate 22, the push plate 8 can be limited to avoid the push plate 8 from shaking during the movement. The top of the push plate 8 is fixedly connected with a pad 23. By setting the pad 23, it is convenient for the user to quickly press the push plate 8 to prevent the user from being unable to quickly press the push plate 8. The top of the push plate 8 passes through the top of the fixed seat 2. The front and rear sides of the arc-shaped card plate 7 are hinged with push-pull plates 9 through pin rods.

[0033] Reference Figure 2-4The side of the push-pull plate 9 away from the arc-shaped card plate 7 is hinged on the surface of the push plate 8 through a pin rod. Both sides of the bottom of the inner cavity of the fixed seat 2 are fixedly connected with support plates 10. Both sides of the support plate 10 are fixedly connected with reinforcement plates 21. The bottom of the reinforcement plate 21 is fixedly connected to the bottom of the inner cavity of the fixed seat 2. By setting the reinforcement plate 21, the connection strength between the support plate 10 and the fixed seat 2 can be increased, and the stability of the support plate 10 is improved. The side of the support plate 10 close to the arc-shaped card plate 7 is fixedly connected with a spring piece 11. The side of the piece 11 away from the support plate 10 is fixedly connected to the surface of the arc-shaped clamping plate 7, the bottom of the fixing seat 2 is fixedly connected with the spring piece 2 12, the bottom of the spring piece 2 12 is fixedly connected with the square plate 13, the bottom of the square plate 13 is fixedly connected with the rubber pad 20, and the bottom of the rubber pad 20 is in contact with the bottom of the inner cavity of the mounting seat 1. By setting the rubber pad 20, the square plate 13 can be protected to prevent the square plate 13 from directly colliding with the fixing seat 2 and causing damage. The surface of the square plate 13 is in contact with the inner wall of the mounting seat 1.

[0034] Reference Figure 3 A cleaning assembly is provided on the top of the mounting frame 3, and the cleaning assembly includes a motor 14, which is fixedly mounted on the top of the mounting frame 3, and the output end of the motor 14 passes through the bottom of the mounting frame 3 and is fixedly connected with a gear 15, and the top of the surface of the camera device body 4 is movably connected with a gear sleeve 16, the gear 15 is meshed with the gear sleeve 16, and the front of the gear sleeve 16 is fixedly connected with a concave plate 17, and the surface of the camera device body 4 is provided with an arc scraper 18, and the front of the arc scraper 18 is fixedly connected to the surface of the concave plate 17. By arranging the motor 14, the gear 15, the gear sleeve 16, the concave plate 17 and the arc scraper 18 structure to cooperate with each other, the lens of the camera device body 4 can be cleaned, and the user is prevented from wiping the lens of the camera device body 4 when it is blurred by dust, thereby reducing labor intensity.

[0035] Reference Figure 1-2 A sealing assembly is provided at the top of the fixed seat 2, and the sealing assembly includes a sealing ring 19. The sealing ring 19 is fixedly connected to the top of the fixed seat 2, and the inner wall of the sealing ring 19 contacts the surface of the push plate 8. By providing the sealing ring 19, the sealing ring 19 can seal the gap between the push plate 8 and the fixed seat 2 to prevent external dust from entering the interior of the fixed seat 2 and affecting the parts inside the fixed seat 2.

[0036] Working principle: During use, when the camera device body 4 fails and needs maintenance, the user first presses the fixing seat 2 downward to move the fixing seat 2 downward, and at the same time presses the push plate 8 downward to move, and the push plate 8 drives the push-pull plate 9 to move through the pin rod, and the push-pull plate 9 drives the arc-shaped card plate 7 to rotate through the shaft rod 6, and at the same time the arc-shaped card plate 7 compresses the spring piece 11 to make the arc-shaped card plate 7 disengage from the inside of the card slot 5, and the camera device body 4 is taken out for maintenance. When the maintenance is completed, it is only necessary to slide the fixing seat 2 into the inside of the mounting seat 1. After reaching the appropriate position, the spring piece 11 drives the arc-shaped card plate 7 to reset through its own elastic force, so that the arc-shaped card plate 7 is inserted into the inside of the card slot 5 to fix the camera device body 4, thereby achieving the advantage of easy maintenance.

[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
