[0002] In the field of video surveillance, the PTZ is used in vehicle-mounted systems, where the PTZ is installed on the top of the vehicle for monitoring. In order to increase the monitoring range of the PTZ, the PTZ needs to be installed higher. When in use, the PTZ is raised, and when not in use, the PTZ is lowered to reduce the height of the equipment to avoid scratches caused by the height limit of the vehicle. Therefore, a lifting bracket with adjustable PTZ installation height is required.

The limit rod 7 is provided in two groups and is symmetrically distributed.

[0027] The lifting mechanism includes a first mounting seat 8, a second motor 9 is fixedly connected in the inner cavity of the first mounting seat 8, a bidirectional screw rod 10 is fixedly connected to the back of the output shaft of the second motor 9, an outer ring of the bidirectional screw rod 10 is threadedly connected to a working block 11, a rotating plate 12 is hinged at the top of the working block 11, and a support plate 13 is fixedly connected to the top of the base plate 1.

[0028] In the embodiment of the utility model, the second motor 9 is started, and the second motor 9 drives the second bidirectional screw 10 to rotate, and drives the working blocks 11 to move closer to or away from each other. Since the rotating plate 12 is hinged at the top of the working block 11, the rotating plate 12 will fold towards each other as the working blocks 11 move closer to each other.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 The top of the rotating plate 12 is hinged with a sliding plate 14, and a lifting plate 15 is installed on the top of the sliding plate 14. The sliding plate 14 and the lifting plate 15 are slidably connected. A telescopic rod 16 is fixedly connected between the lifting plate 15 and the bottom plate 1, and the telescopic rod 16 is arranged in four groups of rectangular arrays.

[0034] When it is necessary to adjust the shooting direction of the gimbal body 25, the third motor 19 is started, and the third motor 19 drives the rotating rod 20 to rotate. Since the rotating plate 21 and the rotating rod 20 are fixed, starting the third motor 19 can drive the rotating plate 21 to rotate, and the direction of the gimbal body 25 can be adjusted under the rotation of the rotating plate 21; through the cooperation of the roller 23 and the connecting rod 24, the gimbal body 25 can be made more stable when rotating.

[0035] When the pan-tilt body 25 is working normally, in order to avoid the high temperature of the pan-tilt body 25, the heat dissipation device 6 is started at this time, and the heat dissipation device 6 can dissipate heat for the pan-tilt body 25, thereby improving the safety of the device; when the heat dissipation range of the heat dissipation device 6 needs to be adjusted, the first motor 3 is started, and the first motor 3 drives the one-way screw rod 4 to rotate, and drives the lifting block 5 to move up and down. Since the heat dissipation device 6 is fixed to the lifting block 5, starting the first motor 3 can drive the heat dissipation device 6 to be lifted and lowered. During the lifting process of the heat dissipation device 6, the heat dissipation range of the heat dissipation device 6 can be adjusted, thereby improving the practicality of the device.
