Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-13 In this embodiment of the present invention, a safety housing for an explosion-proof camera includes a housing 2 for placing a camera 3, and a housing 1 is provided on one side of the housing 2.

[0040] The arc-shaped cover 13 has the same length as the through groove 16, and the width of the arc-shaped cover 13 is greater than the width of the through groove 16. S-pole arc-shaped magnets 18 are provided on both sides of the through groove 16. The length of the two S-pole arc-shaped magnets 18 is less than the length of the through groove 16, and the two S-pole arc-shaped magnets 18 are embedded on the outside of the cylinder 11. N-pole arc-shaped magnets 17 are embedded on both sides of the inner wall of the arc-shaped cover 13. The two N-pole arc-shaped magnets 17 correspond to the positions of the two S-pole arc-shaped magnets 18, and the lengths of the N-pole arc-shaped magnets 17 and S-pole arc-shaped magnets 18 are the same.

[0041] The top of the housing 21 is symmetrically provided with two rotating covers 24, which correspond to the positions of the operation buttons at both ends of the top of the camera 3.

[0042] By adopting the above technical solution, firstly, the rotating door 25 is opened, and then the camera 3 is placed inside the housing 21. The lens of the camera 3 is moved to the outside of the housing 21 through the inner side of the convex ring 22. After the camera 3 is placed, the rotating door 25 is rotated and closed. Then, the cylinder 11 is threadedly connected to the convex ring 22, so that the transparent plate 15 inside the cylinder 11 is located in front of the lens of the camera 3. The transparent plate 15 plays a role in protecting the camera lens, preventing damage to the lens and preventing dust and other impurities from falling onto the lens. After long-term use, the transparent plate 15 will... A certain amount of dust adheres to the tube. At this time, the user can remove the arc-shaped cover 13 and the transparent plate 15 from the cylinder 11 by pulling the handle 14. When removing the transparent plate 15, the cylinder 11 and the shell 21 can still protect the camera 3 normally. When replacing the transparent plate 15, the transparent plate 15 is inserted into the cylinder 11 through the through slot 16. The N-pole arc magnet 17 and the S-pole arc magnet 18 attract each other, so that the arc-shaped cover 13 is tightly attached to the outer wall of the cylinder 11, ensuring the stability of the transparent plate 15 and preventing the transparent plate 15 from shaking or shifting.

[0043] In this embodiment, the housing 21 includes a frame 211, the inner side of which is a space for placing the camera 3; both ends of the top of the frame 211 are provided with rectangular grooves, and the ends of the two rectangular grooves near the cylinder 11 are provided with horizontal connecting shafts 212, and both ends of the two horizontal connecting shafts 212 are fixedly connected to the frame 211; a vertical connecting shaft 213 is integrally provided in the middle of the end of the frame 211 near the revolving door 25; a plurality of magnetic strips 214 are embedded in the end of the frame 211 away from the vertical connecting shaft 213;

[0044] The rotating cover 24 includes a rotating plate 241. The rotating plate 241 has a through hole 243 at one end near the cylinder 11. The transverse connecting shaft 212 is located in the through hole 243, and the rotating plate 241 is rotatably connected to the transverse connecting shaft 212. A push block 242 is fixedly connected to the middle of the end of the rotating plate 241 away from the through hole 243. The upper end of the push block 242 is provided with an anti-slip groove.

[0045] By adopting the above technical solution, when taking a picture, by moving the two push blocks 242, the two rotating plates 241 can rotate around the connection point of the horizontal connecting shaft 212 connected to them, thereby exposing the operation buttons at both ends of the top of the camera 3 for easy operation by the user. When the camera is not in use, the two rotating plates 241 are rotated into a closed state. Both sides of the two rotating plates 241 are downward inclined surfaces, and the top of the frame 211 is inclined upward on the side of the rotating plate 241, so that the inclined surface of the top of the frame 211 is in contact with the inclined surface of the side of the rotating plate 241, allowing the frame 211 to support the rotating plate 241.

[0046] In this embodiment, the revolving door 25 includes a door body 251. A connecting sleeve 253 is integrally provided in the middle of one end of the door body 251 near the vertical connecting shaft 213, and the connecting sleeve 253 is rotatably connected to the vertical connecting shaft 213. A circular through hole is provided at the upper end of the door body 251, and a rubber sleeve 252 is fixedly connected to the side away from the frame 211 at the position corresponding to the circular through hole.

[0047] The door body 251 is provided with a protrusion 254 in the middle of one end away from the connecting sleeve 253. The protrusion 254 is provided with an anti-slip groove on the side away from the door body 251. Multiple magnetic strips 255 are embedded on the side of the door body 251 near the frame 211, and the multiple magnetic strips 255 correspond to the positions of multiple magnetic strips 214 respectively.

[0048] By adopting the above technical solution, after the door 251 is closed, the multiple magnetic strips 255 at the end of the door 251 are attracted to the multiple magnetic strips 214 of the frame 211, thereby allowing the door 251 to be tightly connected to the frame 211 and preventing the door 251 from rotating randomly during the movement of the camera 3.

[0049] The working principle of this utility model is as follows: First, open the rotating door 25, then place the camera 3 inside the housing 21. The lens of the camera 3 moves to the outside of the housing 21 through the inner side of the convex ring 22. After placing the camera 3, rotate and close the rotating door 25. Then, thread the cylinder 11 to the convex ring 22 so that the transparent plate 15 inside the cylinder 11 is located in front of the lens of the camera 3. The transparent plate 15 protects the camera lens, preventing damage and preventing dust and other impurities from falling onto the lens. After prolonged use, the transparent plate 15 will... A certain amount of dust adheres to the tube. At this time, the user can remove the arc-shaped cover 13 and the transparent plate 15 from the cylinder 11 by pulling the handle 14. When removing the transparent plate 15, the cylinder 11 and the shell 21 can still protect the camera 3 normally. When replacing the transparent plate 15, the transparent plate 15 is inserted into the cylinder 11 through the through slot 16. The N-pole arc magnet 17 and the S-pole arc magnet 18 attract each other, so that the arc-shaped cover 13 is tightly attached to the outer wall of the cylinder 11, ensuring the stability of the transparent plate 15 and preventing the transparent plate 15 from shaking or shifting.

[0050] When taking a picture, by moving the two push blocks 242, the two rotating plates 241 can rotate around the connection point of the horizontal connecting shaft 212 connected to them, thereby exposing the operation buttons at both ends of the top of the camera 3 for easy operation. When the camera is not in use, the two rotating plates 241 are rotated into a closed state. Both sides of the two rotating plates 241 are downward inclined surfaces, and the top of the frame 211 is inclined upward with the side of the rotating plate 241. This allows the inclined surface of the top of the frame 211 to fit with the inclined surface of the side of the rotating plate 241, so that the frame 211 can support the rotating plate 241.

[0051] After the door 251 is closed, the multiple magnetic strips 255 at the end of the door 251 are attracted to the multiple magnetic strips 214 of the frame 211, so that the door 251 can be tightly connected to the frame 211 and prevent the door 251 from rotating randomly during the movement of the camera 3.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
