[0040] Specifically, the principle of the utility model is:

[0041] The M-shaped double-rail guide rail is the basis for stable operation of the entire device. Its cross-section is in the shape of M, consisting of an upper rail part, a lower rail part, and a connecting part connecting the two. The inverted U-shaped design of the upper rail part and the U-shaped design of the lower rail part, combined with the inclined connecting part, allow the M-shaped guide rail to fit the sliding platform tightly. This design greatly increases the contact area and friction between the guide rail and the sliding platform, improving the stability of the sliding platform during movement. At the same time, the special shape of the M-shaped double-rail guide rail can effectively disperse the load from the sliding platform and the camera equipment, making it evenly distributed on the guide rail, reducing local stress concentration, and prolonging the service life of the guide rail;

[0042] The M-shaped guide rail sliding platform is installed by sliding into the groove on the bottom of the M-shaped double-rail guide rail. The driving motor drives the gear to rotate and engage with the rack on one side of the M-shaped double-rail guide rail, thereby achieving the movement of the sliding platform. This driving method has precise transmission ratio, can realize smooth and accurate movement of the sliding platform, and meets the needs of different monitoring positions. In addition, the cooperation of the guide wheel and the guide groove further ensures the straightness and stability of the sliding platform during movement, preventing it from deviating and shaking;

[0043] The multi-angle adjustment support platform is installed on the M-shaped guide rail sliding platform through a rotating shaft structure. The bearing in the fixed seat allows the rotating shaft to rotate freely, thereby realizing the rotation of the multi-angle adjustment support platform around the horizontal axis. The design of the inclined support legs not only increases the stability of the support platform, but also optimizes the stress distribution of the support platform by changing the inclination angle and number. The three inclined support legs are evenly distributed in a circle around the rotating shaft, forming a stable triangular support structure that can maintain balance at different rotation angles, ensuring that the camera equipment can work stably under various working conditions.
