In the second arc region (S2), a portion of the second concave portion (222) may be formed concavely radially inward from the first screw insertion portion (240). In other words, the second concave portion (222) may be spaced apart from the first concave portion (221) and the third concave portion (223). The second arc region (S2) may be positioned between the first concave portion (221) and the third concave portion (223) with respect to the circumferential direction.

[0040] The third concave portion (223) may be formed concavely on the outer surface of the stepped body portion (220) in an arc region having a predetermined central angle radially inward. The third concave portion (223) may be formed concavely in an arc region having a central angle greater than the sum of the central angle of the first concave portion (221) and the central angle of the second concave portion (222). The arc region in which such a third concave portion (223) is formed may be named the third arc region (S3). The central angle of the third arc region (S3) may be named the third central angle (Θ3). The third central angle (Θ3) may be larger than the first central angle (Θ1) and the second central angle (Θ2). The third arc region (S3) may be positioned between the first arc region (S1) and the second arc region (S2) based on the circumferential direction. The third concave portion (223) may be spaced apart from the first concave portion (221) and the second concave portion (222).

[0042] Referring further to FIGS. 6 and 7, the screw insertion portion (240) may allow or restrict the penetration of the fastening screw (300) depending on the orientation of the camera body (200) relative to the bracket (100). The screw insertion portion (240) may be formed in the body groove (230). The screw insertion portion (240) may be provided in multiple numbers. The screw insertion portion (240) may be positioned at a location corresponding to the fastening screw (300) when the camera body (200) is in the fixed orientation described later. The screw insertion portion (240) may include a first screw insertion portion (241) and a second screw insertion portion (242).

[0043] Referring further to FIG. 8, the first screw insertion part (241) may allow the fastening screw (300) to pass through depending on the orientation of the camera body (200). The first screw insertion part (241) may be positioned at a location corresponding to the first fastening screw (310) when the camera body (200) is in the separation-allowing orientation described later. Additionally, the first screw insertion part (241) may allow the first fastening screw (310) to pass through when the camera body (200) is in the separation-allowing orientation. The first screw insertion part (241) may be formed in the body groove (230). A first screw insertion hole (241-1) and a first screw guide part (241-2) may be formed in the first screw insertion part (241).

[0044] The first screw insertion hole (241-1) can be penetrated by the first fastening screw (310) when the camera body (200) is in a separation-allowed orientation. The first screw insertion hole (241-1) can be formed by penetrating the camera body (200) in a direction parallel to the axis of rotation. The first screw insertion hole (241-1) can be formed integrally with the body groove (230). The first screw insertion hole (241-1) can be formed on one side of the body groove (230). The width of the first screw insertion hole (241-1) can be greater than the width of the first fastening screw (310).

[0045] The first screw guide portion (241-2) can restrict the separation of the first fastening screw (310). In other words, when the camera body (200) is in a guide orientation, the first screw guide portion (241-2) can interfere with the first fastening screw (310) to restrict the camera body (200) from being separated from the bracket (100). The first screw guide portion (241-2) may have a shape that extends along the circumferential direction. When the camera body (200) is rotated relative to the bracket (100) by an operator, the first fastening screw (310) may move relatively between one side and the other side of the first screw guide portion (241-2). The first screw guide portion (241-2) may be formed on the other side of the body groove (230). The first screw guide portion (241-2) may be formed on the inner side of the body groove (230).

A second screw insertion hole (242-1) and a second screw guide (242-2) may be formed in the second screw insertion part (242).

[0047] The second screw insertion hole (242-1) allows the second fastening screw (320) to pass through when the camera body (200) is in a separation-allowed orientation. The second screw insertion hole (242-1) can be formed by penetrating the camera body (200) in a direction parallel to the rotation axis. The second screw insertion hole (242-1) can be formed integrally with the body groove (230). The second screw insertion hole (242-1) can be formed on one side of the body groove (230). The width of the second screw insertion hole (242-1) can be larger than the width of the second fastening screw (320). The second screw insertion hole (242-1) can be formed symmetrically with respect to the first screw insertion hole (241-1) around a virtual rotation axis.

[0048] The second screw guide portion (242-2) can restrict the separation of the second fastening screw (320). In other words, when the camera body (200) is in a guide orientation, the second screw guide portion (242-2) interferes with the second fastening screw (320) to restrict the camera body (200) from being separated from the bracket (100). The second screw guide portion (242-2) may have a shape that extends along the circumferential direction. When the camera body (200) is rotated relative to the bracket (100) by an operator, the second fastening screw (320) may move relatively between one side and the other side of the second screw guide portion (242-2). The second screw guide portion (242-2) may be formed on the other side of the body groove (230). The second screw guide portion (242-2) may be formed on the inner side of the body groove (230). The circumference of the second screw guide portion (242-2) may be greater than the minimum radius length (d1) of the lens cover portion (270) and smaller than the maximum diameter length (D1) of the lens cover portion (270).

[0049] The indicator guide groove (250) may be extended along the circumferential direction of the camera body (200). When the camera body (200) is rotated relative to the bracket (100), the angle indicator (120) may be moved within the indicator guide groove (250). The indicator guide groove (250) may be formed in a cylindrical shape having the same central angle as the first screw guide (241-2) and the second screw guide (242-2).

[0051] The lens cover portion (270) surrounds the lens (260) and can cover the lens (260). The lens cover portion (270) may protrude further than the stepped body portion (220). The lens cover portion (270) may have a shape in which the diameter decreases toward one side. The radius of one side of the lens cover portion (270) may be the minimum radius length (d1), and the diameter of the other side may be the minimum diameter length (D1).

[0052] The fastening screw (300) can fix the bracket (100) and the camera body (200). Although the fastening screw (300) is illustrated as a screw in FIG. 3, the concept of the present invention is not necessarily limited thereto, and the fastening screw (300) may be omitted. There may be multiple fastening screws (300). When the camera body (200) is rotated relative to the bracket (100), the fastening screw (300) may be restricted or allowed to be separated from the camera body (200). Additionally, when the camera body (200) is separated from the bracket (100), the fastening screw (300) may be allowed to penetrate the screw insertion part (240) when approaching the bracket (100) in a correct fastening orientation, and may be restricted from penetrating the screw insertion part (240) when approaching the bracket (100) in a wrong fastening orientation. The fastening screw (300) may include a first fastening screw (310) and a second fastening screw (320).

[0053] When the camera body (200) approaches the bracket (100) while the camera body (200) is separated from the bracket (100), the orientation in which the camera body (200) allows the insertion of the fastening screw (300) can be named the correct fastening orientation. When the camera body (200) approaches the bracket (100) while the camera body (200) is separated from the bracket (100), the orientation in which the camera body (200) restricts the insertion of one or more of the fastening screws (300) can be named the incorrect fastening orientation.

[0054] When the camera body (200) is in a fixed orientation, the first screw fastening part (111) and the first screw insertion part (241) may be arranged to face each other, and the second screw fastening part (112) and the second screw insertion part (242) may be arranged to face each other. When the camera body (200) is in a fixed orientation with respect to the bracket (100), it may be configured to be placed in a separation-allowing orientation or a guide orientation.

[0055] The fastening screw (300) may be allowed to penetrate the screw insertion portion (240) when the camera body (200) is separated from the bracket (100) and approaches the bracket (100) in a separation-allowing orientation. In other words, when the camera body (200) is in a separation-allowing orientation, it may be allowed to be separated from the bracket (100). For example, the first fastening screw (310) may penetrate the first screw insertion hole (241-1), and the second fastening screw (320) may penetrate the second screw insertion hole (242-1). When the camera body (200) is in a separation-allowing orientation, the first fastening screw (310) may be positioned to face the first screw insertion hole (241-1), and the second fastening screw (320) may be positioned to face the second screw insertion hole (242-1).

[0056] The camera body (200) can be rotated relative to the bracket (100) from the separation-allowing orientation to approach the guide orientation. When the camera body (200) is placed in the guide orientation, the camera body (200) can be rotated relative to the bracket (100) within a predetermined rotation angle. When the camera body (200) is in the guide orientation, the fastening screw (300) may be restricted from penetrating the screw insertion portion (240). In other words, when the camera body (200) is in the guide orientation, separation from the bracket (100) may be restricted. For example, when the camera body (200) is in the guide orientation, some part of the first fastening screw (300) may be allowed to penetrate the first screw guide portion (241-2), and other part of the first fastening screw (300) may be restricted from penetrating the first screw guide portion (241-2). When the camera body (200) is in a guide orientation, some part of the second fastening screw (300) may be allowed to penetrate the second screw guide part (242-2), while other part of the second screw guide part (242-2) may be restricted from penetrating. When the camera body (200) is in a guide orientation, the first fastening screw (310) may be positioned to face the first screw guide part (241-2), and the second fastening screw (320) may be positioned to face the second screw guide part (242-2). When the camera body (200) is in a guide orientation, the degree of insertion of the fastening screw (300) can be adjusted. In other words, when the camera body (200) is in a guide orientation, the operator may tighten the fastening screw (300) further or loosen it further.

[0057] When the camera body (200) is separated from the bracket (100) and approaches the bracket (100) in a misfastening direction, one of the fastening screws (300) may be restricted from penetrating the screw insertion part (240). When the camera body (200) is in the misfastening direction, the camera body (200) may not rotate with respect to the bracket (100).

When the camera body (200) is in a separation-allowing orientation, the second screw head portion (322) may be positioned inside the second screw insertion hole (242-1). When the camera body (200) is in a guide orientation, the width of the second screw head portion (322) is greater than the width of the second screw guide portion (242-2), so the penetration of the second screw head portion (322) into the second screw guide portion (242-2) may be restricted. In other words, when the camera body (200) is in a guide orientation, the second screw head portion (322) can support a part of the camera body (200). When the camera body (200) is in a mis-fastening orientation, a part of the second screw head portion (322) may be restricted from penetrating the first screw guide portion (241-2).

[0064] The operation and effects of a camera assembly (1) having the configuration described above will be explained below.

[0065] When the camera body (200) is rotated relative to the bracket (100), the angle indicator (120) moves relatively within the indicator guide groove (250), and the degree to which the camera body (200) is rotated relative to the bracket (100) may be equal to the degree to which the angle indicator (120) is rotated within the indicator guide groove (250). This has the effect of allowing the operator to check the rotation angle of the camera body (200) based on the rotation angle of the angle indicator (120). The operator can rotate the camera body (200) by a desired angle based on the angle indicator (120).

[0066] After the worker fixes the bracket (100) with the fastening screw (300) attached to the outer wall (2), the camera body (200) can be brought closer to the bracket (100) while the camera body (200) is separated from the bracket (100). The worker can position the camera body (200) in a separation-allowing orientation aligned with a virtual rotation axis direction so that the first screw insertion hole (241-1) faces the first fastening screw (310) and the second screw insertion hole (242-1) faces the second fastening screw (320). The worker can rotate the camera body (200) around the virtual rotation axis from the separation-allowing orientation to position it in a guide orientation. When the camera body (200) is in a guide orientation, the penetration of the first screw head part (312) and the second screw head part (322) into the first screw guide part (241-2) and the second screw guide part (242-2) may be restricted. When the camera body (200) is in a guide orientation, the operator can connect the camera body (200) to the bracket (100) without the camera body (200) falling off, even without fully tightening the fastening screw (300). In other words, the operator can attach the camera body (200) to the bracket (100) with only a simple operation of rotating the camera body (200) from the detachable state to the guide orientation.

[0067] When the connection orientation is incorrect, interference occurs, such as the first screw body part (311) being restricted from penetrating the second screw guide part (242-2) and a part of the first screw head part (312) being restricted from penetrating the second screw insertion hole (242-1), and the connection between the bracket (100) and the camera body (200) may be restricted. This has the effect of guiding the connection between the bracket (100) and the camera body (200) in the correct connection orientation, allowing the operator to easily fix it in the correct direction.
