DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 A pan / tilt camera shown in the figure comprises a base 1, a shaft-rotating bracket 2 is arranged on the base 1, a connecting seat 3 is arranged on the shaft-rotating bracket 2, a camera platform 4 is movably mounted on the connecting seat 3, a driving assembly is arranged between the camera platform 4 and the connecting seat 3, the camera platform 4 is fixedly mounted on the driving assembly, and the camera platform 4 is movably connected to the connecting seat 3. Connecting columns 16 are arranged on the outer walls on opposite sides of the camera platform 4, and the connecting columns 16 are movably connected to the connecting seat 3. The connecting seat 3 is a hollow hemisphere, and the connecting columns 16 are rotatably mounted at the axis of the connecting seat 3. A camera body 17 is fixedly connected to the camera platform 4.

[0021] First, fix the base 1 on a stable object, and the inclination angle of the base 1 is adjustable. The original angle can be tilted in the rotation direction of the rotating plate 14 with the fixed plate 12 as the base point, and the angle of the base 1 is fixed by the threaded holes set on the fixed plate 12 and the fixed plate 2, so that the angle of the shaft rotating bracket 2 can be tilted, so that when in use, the power gear 10 and the internal gear 11 set on the shaft rotating bracket 2 can cooperate to rotate the camera body 17 horizontally, and the driving gear 5 and the arc gear can cooperate to drive the camera body 17 to adjust the vertical direction. Through the cooperation of horizontal rotation and vertical rotation, the driving of the camera body 17 is simply and conveniently realized to achieve shooting of a larger angle area, which is easy to use.

[0022] Specifically, the base 1 includes a fixed plate 12, a fixed plate 13 and a rotating plate 14. One end of the fixed plate 12 is fixedly connected to the shaft rotating bracket 2, the rotating plate 14 is rotatably connected to the fixed plate 12, the fixed plate 13 is rotatably connected to the rotating plate 14, and the fixed plate 12 and the fixed plate 13 are both provided with threaded holes 15. Figure 1As shown in or 3, the angle of the base 1 can be adjusted during installation to suit the actual use angle, so as to avoid the need for long-term and large-angle rotation for monitoring at low places when the angle is high, which causes inconvenience in use. Specifically: if necessary, a gasket for adapting the rotation angle of the rotating plate 14 can be added to the fixed plate 12, and the gasket is connected between the fixed plate 12 and the screw, so that when the angle of the rotating plate 14 is large, the gasket is added to make the screw perpendicular to the surface of the fixed object, so as to increase the stability of the bolt 15. In subsequent use, the angle between the fixed plate 12 and the rotating plate 14 remains fixed, so that the axial rotation bracket 2 is in a stable state, avoiding the problem of inconvenience caused by instability.

[0023] Specifically, the driving assembly includes a driving gear 5 and an arc-shaped toothed plate 6. The connecting seat 3 is provided with a mounting opening 7. The driving gear 5 is movably mounted in the mounting opening 7 and is fixedly connected to the output end of the driving motor. The driving gear 5 is meshed with the arc-shaped toothed plate 6. The camera platform 4 is fixedly mounted on the arc-shaped toothed plate 6. Figure 3 As shown, the driving motor drives the driving gear 5 to rotate, so that the arc-shaped toothed plate 6 moves. Since the camera platform 4 connected to the arc-shaped toothed plate 6 is rotatably connected to the connecting seat 3 through the connecting column 16, when the arc-shaped toothed plate 6 is driven, the camera platform 4 will rotate up or down by a certain angle with the connection point between the connecting column 16 and the connecting seat 3 as the base point. The camera body 17 located on the camera platform 4 will also rotate with the position of the arc-shaped toothed plate 6 to achieve an upward or downward angle offset, thereby achieving the purpose of shooting high or low scenes.

[0024] Specifically, the shaft rotating bracket 2 is in an arc shape, and mounting blocks 8 are respectively provided at both ends of the arc shape of the shaft rotating bracket 2. A power gear 10 is rotatably mounted on the mounting block 8. A connecting groove 9 is provided on the connecting seat 3. An internal gear 11 is fixedly connected to the inner wall of the connecting groove 9. The power gear 10 meshes with the internal gear 11. The mounting block 8 is fixedly connected to the outer wall of the connecting seat 3. Please refer to the attached Figure 1 As shown, the connecting seat 3 is connected to the mounting block 8 via a connecting shaft arranged in the connecting groove 9, and then is rotatably mounted on the shaft-rotating bracket 2. The power gear 10 drives the internal gear 11 to rotate, thereby driving the connecting seat 3 to rotate with the connecting shaft as the axis point, and driving the camera platform 4 installed on the connecting seat 3 to rotate synchronously, so as to adjust the horizontal angle of the camera body 17 to meet the actual shooting needs at the use angle.
