[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1 to 3 In this embodiment, a surveillance camera with the function of increasing the monitoring range includes a support column 1, and a rotation adjustment mechanism is provided on the top of the support column 1.

[0021] In this embodiment, the rotation adjustment mechanism includes a mounting box 2 fixedly installed on the top of the support column 1. A rotary motor 3 is fixedly installed inside the mounting box 2. A rotating shaft 4 extending to the outside of the mounting box 2 is fixedly installed on the output shaft of the rotary motor 3. A rotation groove is provided on the top of the mounting box 2. The rotating shaft 4 is rotatably connected to the mounting box 2 through the rotation groove, so as to facilitate the rotation of the rotating shaft 4.

[0022] The top of the rotating shaft 4 is fixedly mounted with a mounting base 5, the inside of the mounting base 5 is fixedly mounted with a drive motor 6, the output shaft of the drive motor 6 is fixedly mounted with a rotating rod 7, the inside of the drive gear 8 is provided with a fixing groove, and the drive gear 8 is fixedly connected to the rotating rod 7 through the fixing groove, which helps the rotating rod 7 to drive the drive gear 8 to rotate.

[0023] In this embodiment, a drive gear 8 is fixedly installed on the outer side of the rotating rod 7, and a driven gear 9 is meshed on the top of the drive gear 8. The driven gear 9 is a semi-circular gear, and the speed ratio between the drive gear 8 and the driven gear 9 is three to one, which facilitates rotational drive. A mounting frame 10 is fixedly installed on the top of the driven gear 9, and limiting blocks 11 that are slidably connected to the mounting base 5 are fixedly installed on both the left and right sides of the mounting frame 10.

[0024] The mounting base 5 has semi-circular grooves on its inner walls on both sides. The limiting block 11 is slidably connected to the mounting base 5 through the grooves, which helps to more effectively limit the limiting block 11 and the mounting frame 10. The rotation adjustment mechanism also includes a camera body 12 fixedly installed inside the mounting frame 10, and a canopy 13 fixedly installed on the top of the mounting frame 10.

[0025] It should be noted that this surveillance camera with the function of increasing the monitoring range, through the set rotation adjustment mechanism, uses the rotary motor 3 to drive the rotating shaft 4 and the mounting base 5 to rotate, realizing the free rotation of the camera on the horizontal plane, which can cover a larger monitoring area. The drive motor 6 uses the drive gear 8 and the driven gear 9 to drive the mounting frame 10 to rotate, realizing the adjustment of the vertical angle of the camera, which greatly increases the three-dimensional space range of the monitoring. The combination of free adjustment in the horizontal and vertical directions can reduce the blind spots of the monitoring and ensure that every corner of the monitoring area can be effectively covered, thereby improving security. The canopy 13 on the top of the mounting frame 10 can effectively block rain, sunlight, dust and other damage to the camera body 12, extend the service life of the camera and reduce equipment failure caused by environmental factors.

[0026] The working principle of the above embodiments is as follows:

[0027] This surveillance camera, which has the function of increasing the monitoring range, starts the rotary motor 3 to drive the rotating shaft 4 to rotate when in use. Since the rotating shaft 4 is rotatably connected to the mounting box 2 through the rotating groove, the rotating shaft 4 can rotate stably in the rotating groove at the top of the mounting box 2. The top of the rotating shaft 4 is fixed with the mounting base 5, so the mounting base 5 will rotate horizontally together with the rotating shaft 4, realizing the angle adjustment of the camera in the horizontal direction, thereby expanding the horizontal monitoring range. The drive motor 6 can also be started to drive the rotating rod 7 to rotate.

[0028] The drive gear 8 fixed on the rotating rod 7 rotates accordingly, and the drive gear 8 meshes with the driven gear 9. Since the speed ratio of the drive gear 8 to the driven gear 9 is three to one, when the drive gear 8 rotates, it will drive the driven gear 9 to rotate. The driven gear 9 rotates at a relatively slower speed. The top of the driven gear 9 is fixed with a mounting frame 10. The limiting blocks 11 on the left and right sides of the mounting frame 10 slide in the semi-circular grooves on the inner walls of the left and right sides of the mounting base 5, ensuring that the mounting frame 10 rotates stably in the vertical direction. The camera body 12 is fixed inside the mounting frame 10. Therefore, as the mounting frame 10 rotates, the camera body 12 can achieve vertical angle adjustment, further expanding the vertical monitoring range. The shield 13 on the top of the mounting frame 10 can shield and protect the camera body 12, preventing damage from rain, direct sunlight, etc., and ensuring that the camera can work normally and monitor stably under various weather conditions, greatly increasing the flexibility and practicality of the device.
