It should be noted that, according to actual needs, the bearing 16 and the bearing seat 15 may be deleted, and when the bearing 16 and the bearing seat 15 are deleted, the purpose of the rotary driver 13 driving the bracket 12 to rotate relative to the ball body 11 is not affected. More specifically, the following is:

as shown in fig. 2, 4, 6 and 8, a mounting hole 123 is formed in the middle position of the bracket 12 and is located right above the space 122 surrounded by the tubular structure 121, and the mounting hole 123 penetrates the upper end wall 1211 of the tubular structure 121 downwards to communicate with the space 122 surrounded by the tubular structure 121; a locking screw 14 passes through the mounting hole 123 downwards and is in threaded connection with the output end 131 of the rotary driver 13, so that the output end 131 of the rotary driver 13 is abutted and fixed with the upper end wall 1211 of the cylindrical structure 121 in the up-down direction of the ball body 11, and the state is shown in fig. 4; this design makes the assembly and disassembly operations between the bracket 12 and the output end 131 of the rotary drive 13 more convenient and efficient. Specifically, in fig. 2, 4, 6 and 8, as an example, the mounting hole 123 is a counter bore, and the locking screw 14 is sunk into the mounting hole 123 to prevent the locking screw 14 from protruding upwards out of the mounting hole 123 to obstruct the ball 20 assembled at the bracket 12, so that the gap between the ball 20 and the bracket 12 can be made smaller, and the assembly between the ball 20 and the bracket 12 is more compact. For example, in fig. 2 and 6, the mounting hole 123 is a circular hole, so that the mounting hole 123 can be manufactured on the bracket 12, and of course, the mounting hole 123 can be a hole with other shapes according to practical needs, and is not limited to the one shown in fig. 2 and 6.

As shown in fig. 2 and 5, the ball 11 has a housing cavity 111 with an opening 1111 facing upwards, and the rotary driver 13, the bearing seat 15 and the bearing 16 are respectively located in the housing cavity 111 to hide the rotary driver 13, the bearing seat 15 and the bearing 16 in the ball 11, and the bracket 12 covers the opening 1111 of the housing cavity 111, so that the dome camera 100 of the present utility model is more compact. Specifically, in fig. 2 and 9, as an example, the bearing seat 15 includes a circular cylinder 151 and three mounting lugs 152 located outside the circular cylinder 151 and arranged at intervals along the circumferential direction of the circular cylinder 151, an inner sidewall 1511 of the circular cylinder 151 protrudes inward along the radial direction of the circular cylinder 151 to form a bearing boss 1512, the mounting lugs 152 are fixedly connected with the circular cylinder 151 and provided with mounting holes 1521, fixing screws 17 for fixedly connecting the mounting lugs 152 with the ball body 11 are inserted into the mounting holes 1521, and the bearing 16 is located in the circular cylinder 151 and supported by the bearing boss 1512; this design makes the fixing of the bearing housing 15 to the ball 11 more reliable and the assembly of the bearing 16 at the bearing housing 15 more reliable. More specifically, as shown in fig. 2, 4 and 5, the body 11 further has upper and lower supporting bodies 112 located in the accommodation chamber 111 and located right below the mounting lugs 152, the number of the upper and lower supporting bodies 112 is the same as that of the mounting lugs 152, and the fixing screws 17 are screw-coupled with the upper and lower supporting bodies 112 to support the bearing housing 15 at a position of the accommodation chamber 111 away from the bottom of the body 11 by means of the upper and lower supporting bodies 112, thereby reasonably utilizing other positions of the accommodation chamber 111; in addition, the ball body 11 further has a bearing limit structure 113 located in the accommodating cavity 111, the bearing limit structure 113 includes a bearing structure 1131 for bearing the rotary driver 13 and an annular limit structure 1132 for limiting the rotary driver 13 from the lateral direction, the bearing structure 1131 is located in the annular limit structure 1132, and all the upper and lower supporting bodies 112 surround the bearing limit structure 113 from the periphery; the rotary actuator 13 is more reliably mounted to the body 11 by the support and limit structure 113. For example, in fig. 5, as an example, the annular limiting structure 1132 is disposed in a non-closed loop, i.e. the end-to-end of the annular limiting structure 1132 is not closed but is opened, so that the rotary driver 13 performs the routing operation through the opening of the annular limiting structure 1132; the supporting structure 1131 is composed of a plurality of blocks which are arranged along the circumferential direction of the annular limiting structure 1132 in a spaced mode, so that the rotating driver 13 is supported from a plurality of positions, and the reliability of the supporting of the rotating driver 13 by the supporting structure 1131 is improved; in addition, the rotary driver 13 is a motor; in addition, the fitting hole 1521 is a circular hole, and of course, the fitting hole 1521 may be a hole of other shapes according to actual needs. It should be noted that, although fig. 9 shows three mounting lugs 152, the number of the mounting lugs 152 may be two, four or five according to actual needs, and thus, the present utility model is not limited to the one shown in fig. 9.

Compared with the prior art, the rotary driver 13 directly drives the bracket 12 to rotate by means of the direct sleeving and fixed connection of the cylindrical structure 121 at the middle position of the bracket 12 and the output end 131 of the rotary driver 13, so that the bracket 12 can be driven to rotate by the rotary driver 13 without two gears; because the rotary driver 13 does not need two gears to drive the bracket 12 to rotate, no virtual position is generated, the installation of the bracket 12 and the rotary driver 13 can be quickened, and the installation efficiency is improved; in addition, as gears are not needed, the cost is correspondingly reduced and the cost of the whole machine is saved.

It should be noted that the direction indicated by the arrow a in the drawing is the direction from top to bottom of the ball 11, and correspondingly, the opposite direction indicated by the arrow a in the drawing is the direction from bottom to top of the ball 11. In addition, since the rotary driver 13 is inserted into the tubular structure 121 of the bracket 12 through the output end 131 thereof and fixed with the tubular structure 121 to drive the bracket 12 to rotate, the tubular structure 121 also blocks the output end 131 inserted into the tubular structure 121 from rotating relative to the tubular structure 121. In addition, the tubular structure 121 of the bracket 12 may be fixed to the output end 131 of the rotary driver 13 by a locking screw 14, or may be fixed to the tubular structure 121 by a pin inserted transversely through both the output end 131 and the tubular structure 121.
