Description

Technical Field

[0001] The utility model relates to the technical field of security monitoring, in particular to a security monitoring device with good stability. Background Art

[0002] Monitoring is one of the most widely used systems in security systems. In order to improve the monitoring effect, most cameras are equipped with brackets, which are used to install the cameras at high places. In order to facilitate monitoring, the brackets can be adjusted to a certain angle. However, most of the existing adjustable brackets use the friction between two adjacent rotating rods for support. After long-term use, the brackets will rotate, making the installed cameras unstable and affecting the monitoring effect of the cameras.

[0003] After searching, the publication number is: CN214744761U, a security monitoring device with good stability, including a camera body, a mounting box is provided under the camera body, the bottom of the mounting box is rotatably connected with an adjustment shaft, the top of the adjustment shaft passes through the mounting box and is rotatably connected to the lower surface of the camera body, the inner side wall of the camera body is connected to an adjustment mechanism for adjusting the rotation of the adjustment shaft; the bottom of the mounting box is fixedly connected to a mounting rod.

[0004] The above technical solution has the following shortcomings:

[0005] First, the above technical solution uses the friction between the arc-shaped clamping plate and the protective pattern to limit the rotation rod, which does not rule out the possibility that the camera body will still shake when the wind is strong during outdoor use;

[0006] Second, the angle adjustment of the camera body needs to be carried out by driving the threaded sleeve. However, during the adjustment process, the threaded sleeve is affected by the traction force of the camera body, which increases the friction between it and the two threaded rods, thereby affecting the normal progress of the adjustment process.

[0028] A U-shaped rod 10 is fixedly provided on the rod wall of the fixed rod 4, and a slider 11 is movably sleeved on the rod wall of the U-shaped rod 10. A connecting mechanism is provided between the slider 11 and the hollow block 3. A limiting mechanism is provided on the top of the slider 11. A plurality of limiting grooves are provided on the upper surface of the U-shaped rod 10, and each limiting groove matches the limiting mechanism.

[0029] like Figure 3 As shown, the limiting mechanism includes an L-shaped plate 12 and a limiting rod 13. The L-shaped plate 12 is fixedly arranged on the top of the slider 11. Through holes are provided at the top of the slider 11 and the top of the L-shaped plate 12. The limiting rod 13 is movably arranged inside the two through holes and movably plugged into the corresponding limiting grooves.
