Description

CCTV Camera Angle Adjuster The present embodiment relates to an angle adjustment device for a CCTV camera for adjusting the angle of a CCTV camera, and more specifically, to an angle adjustment device for a CCTV camera that facilitates easy adjustment of the rotational, vertical, and horizontal angles of the CCTV camera and can firmly maintain the position of the CCTV camera after adjusting its direction. Generally, CCTV cameras are used for crime prevention in ordinary households, or installed in places such as department stores, banks, and exhibition halls to prevent and stop intrusion, theft, or fire in advance, and to handle accidents quickly if they occur. Additionally, on general city roads and highways, closed-circuit surveillance cameras (CCTV: Closed Circuit Television) systems are used to monitor traffic conditions and crack down on violating vehicles. In particular, such CCTV camera systems are installed in specific locations for a special purpose and are used to monitor video from a remote location in order to supervise all situations. Generally, these CCTV cameras are installed on the upper part of the building walls or ceilings and set up to face a specific direction so that they can monitor as wide an area as possible. A conventional CCTV camera comprises a camera body, a mounting bracket, and an angle adjustment member consisting of a ball joint that connects the body and the bracket to adjust the shooting angle. The bracket is attached to the wall, ceiling, or pillar of a building, and data transmitted from a recording device embedded in the body is sent via a cable to an unillustrated display device, after which the current status can be determined through a monitor serving as the display unit. Additionally, the angle adjustment member is configured such that a ball joint is rotatably coupled to the front end of the bracket, with the other end attached to the bottom surface of the body; in some cases, it may be coupled to the rear surface of the body. However, the angle adjustment member described above is limited to adjusting an angle within a predetermined range by means of a single ball joint on one side, and in particular, since the cable connected to the imaging device inside the main body is exposed to the outside, there was a problem in that the cable could be severed by external factors, rendering the function paralyzed, and there was a loss of cost for repairing it. A conventional technology that solves the aforementioned problems includes the "angle adjustment device for a CCTV camera" disclosed in Korean Registered Patent No. 10-0438100, which, as illustrated in the attached Fig. 9, comprises a support member (140) in which a male screw (142) and a ball (143) are respectively formed at both ends of a shaft (141) of a predetermined length, an assembly ball (170) in which a female screw (171) is formed to be fastened to the male screw (142) of the shaft (141), and first and second fixing members (150, 150') and first and second tightening members (160, 160') that are divided to surround and fix the ball (143) of the support member (140) and the assembly ball (170). Male screws (151, 151') and female screws (161, 161') are respectively formed on the first and second fixing members (150, 150') and the first and second tightening members (160, 10') so that the fixing members (150, 150') and the tightening members (160, 160') are mutually fastened, and the first and second tightening members (160, 160') are fitted onto the shaft (141) of the support member (140) and arranged thereon, and flanges (153, 153') are formed on the first and second fixing members (150, 150') so that they can be attached to the camera body (100) and the bracket (120), and the shaft (141) and ball (143) of the support member (140) and assembly A through hole (190, 190') is formed in the central longitudinal direction of the ball (170) so that a cable is inserted into the through hole (190, 190') and not exposed to the outside, thereby allowing the direction and height of the camera body to be adjusted according to the tightening state of the tightening member (160, 160'). However, in the conventional angle adjustment device for a CCTV camera, the ball (143) formed in the support member (140) and the assembly ball (170) coupled to the support member (140) are inserted into the fixing member (150, 150') and then fixed by the tightening member (160, 160'), and since the spherical surface of the ball (143, 170) and the inner surface of the fixing member (150, 150') are simply in surface contact, there was a problem that when the camera body (100) shakes due to external impact or surrounding vibration, the ball (143, 170) coupled to the fixing member (150, 150') moves due to the weight of the camera body (100), causing the direction and height of the camera to be distorted.
