The outer surface of the threaded rod 9 is threadedly connected to the inner center of the sealing block 11, and a threaded hole matching the threaded rod 9 is provided at the inner center of the sealing block 11. The inner movably plug-in limit rod 12 of the sealing block 11 is provided, and the end of the sealing groove 10 away from the dual-axis motor 6 is fixedly connected with a vent pipe 13, and the end of the limit rod 12 away from the vent pipe 13 is fixedly connected to the inner wall of the sealing groove 10. Through the baffle 3, when the camera body 1 is not in use, the lens 101 can be covered by rotating the baffle 3, so as to prevent dust from falling on the surface of the lens 101 and affecting the normal monitoring of the picture. By setting the baffle 3, when the camera body 1 is in use, the baffle 3 can be unfolded to block the top of the lens 101, and can block or reduce the reflection of the lens surface when the light is strong or at a specific angle, so as to prevent the light from directly entering the lens to cause light spots or reflections, thereby improving the clarity and quality of the captured picture.

[0021] A fixed box 14 is fixedly connected at the center of the surface of the baffle 3, and the end of the sealing groove 10 away from the dual-axis motor 6 is connected to the interior of the fixed box 14 through the ventilation pipe 13. The interior of the fixed box 14 is sealed and slidably connected with a sealing plate 15, and a sealing ring is fixedly installed on the outer surface of the sealing plate 15.

By arranging the fixed box 14, the sealing plate 15 and the bonding plate 16, when the baffle 3 rotates, the sealing plate 15 will slide inside the fixed box 14 to ensure that after the baffle 3 covers the lens 101, the surface of the bonding plate 16 can be against the surface of the lens 101, thereby avoiding the formation of a gap between the lens 101 and the baffle 3, which is easy to get dust, thereby enhancing practicality.

[0022] When the camera body 1 is not in use, the dual-axis motor 6 is started, and the dual-axis motor 6 drives the driving bevel gear 7 to rotate, and the driving bevel gear 7 is meshed with the driven bevel gear 8 to make the baffle 3 rotate around the fixed rod 5. When the baffle 3 rotates ninety degrees, the surface of the baffle 3 fits with the surface of the camera body 1. When the dual-axis motor 6 is started, the threaded rod 9 is driven to rotate, and the sealing block 11 slides inside the sealing groove 10. At this time, the inside of the sealing groove 10 is in a strong pressure state. At the same time, the sealing plate 15 drives the bonding plate 16 to slide toward the surface of the lens 101, ensuring that after the baffle 3 covers the lens 101, the surface of the bonding plate 16 can be against the surface of the lens 101, avoiding the gap between the lens 101 and the baffle 3, which is easy to get dust, thereby enhancing practicality. When the camera body 1 is in use, after the baffle 3 is unfolded, the top of the lens 101 can be blocked, and when the light is strong or at a specific angle, the reflection of the lens surface can be blocked or reduced, avoiding the direct light entering the lens to cause light spots or reflections, thereby improving the clarity and quality of the captured image.
