[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This cold chain storage environment monitoring device, through a fixed structure, uses a first motor to drive a second gear to mesh with the first gear, which in turn drives a double-ended threaded rod to rotate precisely. The threaded transmission enables a pair of clamping frames to move synchronously and symmetrically. The rigid contact between the clamping plate and the side wall of the monitoring body ensures absolute stability during fixation. The symmetrical design of the double-ended threaded rod ensures uniform distribution of clamping force, avoiding the risk of equipment displacement caused by unilateral force. This mechanism combines the convenience of electric control with the reliability of mechanical transmission. The clamping process is smooth and controllable, and disassembly is simple and quick, perfectly solving the problems of positioning accuracy and operational efficiency during the installation and maintenance of monitoring equipment. The entire system adopts a modular design, with transmission components fitting precisely without gaps. This not only meets the need for rapid installation of monitoring bodies of different specifications but also ensures robustness during long-term use through mechanical self-locking characteristics.

[0016] 2. This cold chain storage environment monitoring device, through its adjustable structure, employs a dual-module collaborative control architecture to achieve omnidirectional precise positioning. Horizontal rotation adjustment is achieved via a worm gear transmission mechanism, whose self-locking characteristic ensures stable holding at any angle. Simultaneously, a precision pulley and screw system enables vertical lifting control, with the synergistic effect of the transmission belt and guide frame guaranteeing the smoothness and accuracy of height adjustment. The entire system efficiently converts motor power into multi-dimensional motion through a modular mechanical transmission chain. The cooperation between the rotating shaft and the circular guide rail achieves stepless horizontal rotation positioning, while the screw transmission mechanism provides millimeter-level precision lifting in the vertical direction. These two adjustment modes can operate independently or in tandem, perfectly meeting the complex positioning needs of monitoring equipment at multiple angles and heights. All transmission components of the system adopt industrial-grade precision fitting standards, ensuring smooth operation without backlash. The motor drive response is rapid, and noise control is excellent. This not only significantly improves the adjustment efficiency and positioning accuracy of the monitoring equipment but also ensures absolute stability of the working state through the mechanical self-locking mechanism.
