Please refer to FIG. 4A and FIG. 4B. FIG. 4A is a cross-sectional view of the photographing device installed on a rack according to the first embodiment. FIG. 4B is a cross-sectional view of the photographing device in FIG. 4A when the photographing device 10 rotates an angle. In this embodiment, the photographing device 10 is installed on a rack 20 having an orifice 22. The following describes the steps of installing the photographing device 10 on the rack 20.
First, the second end 114 of the hollow case 110 passes through the orifice 22 of the rack 20. Second, the second annular fastener 500 is screwed to the hollow case 110 so that the rack 20 is interposed between the first stopping part 400 and the second stopping part 520 so as to fix the hollow case 110 to the rack 20. Third, the first annular fastener 300 is screwed to the hollow case 110 so as to locate the image capturing component 200 in the supporting space 115 of the hollow case 110. Fourth, the first annular fastener 300 is rotated to be locked to the hollow case 110.
Specifically, before the first annular fastener 300 is not completely locked to the hollow case 110, the image capturing component 200 is able to rotate relative to the hollow case 110 so as to adjust the image-capturing angle of the image capturing component 200 (as shown in FIG. 4B). When the image-capturing angle of the image capturing component 200 is adjusted, the limiting part 225 interferes with the protruding part 120 to prevent the lens 240 from being covered by the first annular fastener 300 and the hollow case 110. When the image capturing component 200 rotates, the alignment mark 215 is configured to make sure the image capturing component 200 in a correct orientation so as to ensure that the image captured by the lens 240 is correct rather than up-side-down. After the image capturing component 200 is located in the supporting space 115, opposite two sides of the image capturing component 200 is pressed against a supporting surface 121 of the protruding part 120 and a touching surface 321 of the annular abutting part 320, respectively. Since the shape of the image capturing component 200 is spherical, the supporting surface 121 and the touching surface 321 can be curved so that it is favorable for rotating the image capturing component 200 relative to the hollow case 110 to adjust the image-capturing angle of the image capturing component 200. Furthermore, the camera body 700 can be fixed to a position of the rack 20 having better invisibility and better anti-explosiveness by a screw or a nail.
In this embodiment, the image capturing component 200 is located in the supporting space 115 after the hollow case 110 passes through the orifice 22 of the rack 20, but the disclosure is not limited thereto. In some other embodiments, the image capturing component 200 can be located in the supporting space 115 before the hollow case 110 passes through the orifice 22.
According to the aforementioned configurations and installation steps of the photographing device 10, a user is able to assemble the image capturing component 200 to the hollow case 110 conveniently, and the photographing device 10 is able to be installed on the rack 20 no matter the thickness of the rack 20 is by fastening the first annular fastener 300 and the second annular fastener 500 to the hollow case 110. Therefore, it is favorable for efficiently assembling the photographing device 10.
Furthermore, the lens 240 and the image sensor 250 are both separated from the camera body 700 so as to miniaturize the image capturing component 200 to decrease the volume of the photographing device 10 exposed to outside, thereby improving the invisibility and the anti-explosiveness of the photographing device 10.
Moreover, the image capturing component 200 is miniaturized and the orifice 22 of the rack 20 veils the photographing device 10, thereby further improving the invisibility and the anti-explosiveness of the photographing device 10.
