Through the setting of the anti-slip fixing mechanism 4, the cables connected to the device can be effectively protected and fixed. This mechanism ensures that the cables can be stably plugged into the wiring port 3, thereby effectively avoiding unnecessary bending and falling of the cables during the use of the device. Such a design not only helps to maintain the operating stability of the device, but also can orderly comb multiple cables to prevent them from getting entangled and interfering with each other. In this way, the measurement and control accuracy of the device can be significantly improved, while reducing the difficulty of subsequent maintenance. The design of this anti-slip fixing mechanism fully considers the actual use needs and ensures the reliability and efficiency of the device in various working environments.

[0024] according to Figure 1 , Figure 2 and Figure 7As shown, the multi-directional mounting mechanism 6 includes a first ear seat 601, which is fixedly mounted on one side of the low-voltage measurement and control device body 1, and the inner side of the first ear seat 601 is rotatably connected to the second ear seat 602, and the inner side of the second ear seat 602 is rotatably connected to the first connecting rod 603, one end of the first connecting rod 603 is rotatably connected to the second connecting rod 604, and one end of the second connecting rod 604 is rotatably connected to the third ear seat 605, and one end of the third ear seat 605 is fixedly mounted with a mounting seat 606, and one side of the mounting seat 606 is mounted with two first fastening bolts 607.

[0025] according to Figure 2 , Figure 5 and Figure 6 As shown, the drive transmission mechanism 5 includes a connecting shaft 501, one end of each connecting shaft 501 is movable through a fixing frame 401 and connected to a corresponding screw rod 402, a pulley 502 is installed on the outer side of each connecting shaft 501, and a transmission belt 503 is sleeved on the outer side of the two pulleys 502, a worm wheel 504 is installed on the outer side of a single connecting shaft 501, and a worm 505 is meshedly connected on the outer side of the worm wheel 504, and a sealing housing 506 is arranged on the outer side of the worm wheel 504 and the worm 505, and one end of the worm 505 is movable through the sealing housing 506.

In addition, the device also has a self-locking function, which can effectively prevent unnecessary spinning of the related drive shaft, further improving the stability of the device during use.

[0026] according to Figure 2 , Figure 7 and Figure 8As shown, the support shock absorbing mechanism 7 includes two dampers 701, and the damper 701 is fixedly installed on one side of the first connecting rod 603. The outer side of each damper 701 is sleeved with a second spring 702. One end of the two dampers 701 is fixedly connected with an anti-slip support plate 703, and the anti-slip support plate 703 is attached to one side of the protective shell 2. Through the setting of the support shock absorbing mechanism 7, the device can obtain stable support and efficient shock absorbing effect. The support shock absorbing mechanism 7 can absorb and significantly reduce the force generated by various vibrations, thereby reducing the impact that the device may suffer during operation. In addition, by strengthening the support connection with the protective shell 2, unnecessary shaking of the device due to the influence of external environmental factors can be effectively avoided. Such a design not only protects the device from potential damage, but also helps to extend the service life of the device and ensure its stability and reliability under various working conditions.

[0027] according to Figure 4 As shown, an integrated circuit board 8 is arranged on the inner side of the protective shell 2, and mounting bolts 9 are installed on the four corners of one side of the integrated circuit board 8. Through the arrangement of the integrated circuit board 8 and the matching mounting bolts 9, it can be ensured that the key components of the device are firmly fixed and installed in the internal space of the protective shell 2, thereby providing a safe and reliable environment for these important components to ensure that they are protected from interference and damage by external factors. In addition, the integrated circuit board 8 is not just a simple circuit carrier, it integrates a variety of functional unit modules, including but not limited to voltage measurement, current measurement, short circuit protection, overload protection, undervoltage and overvoltage protection, remote control, local control and wireless communication, etc. The integration of these functional modules enables the entire device to have comprehensive and powerful operating functions, and can flexibly respond to various complex requirements of low-voltage measurement and control, providing users with great convenience and efficient operation experience. The integrated circuit board 8 is a prior art known to those skilled in the art, and this scheme does not make relevant technical improvements to it, so its specific working principle is not elaborated in this article.

[0028] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vent 10 is provided through one side of the protective shell 2, and dustproof mesh covers 11 are symmetrically provided on both sides of the protective shell 2. The vent 10 can ensure smooth air circulation and ventilation inside the protective shell 2, thereby effectively preventing heat accumulation inside the protective shell and avoiding potential damage to electronic components due to excessive temperature. In addition, by installing the dustproof mesh cover 11, the intrusion of external dust can be effectively blocked, and the internal electronic components can be protected from dust. Such a design not only helps to extend the service life of the device, but also significantly reduces the difficulty and frequency of later maintenance, thereby saving operation and maintenance costs to a great extent.

[0029] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, two cooling fans 12 are installed on one side of the protective shell 2, and the two cooling fans 12 are both arranged on the inner side of a single dustproof mesh cover 11. Through the arrangement of the cooling fans 12, the heat dissipation efficiency inside the device can be significantly improved, thereby quickly dissipating the accumulated heat and effectively preventing damage to internal electronic components caused by heat accumulation. This efficient heat dissipation mechanism can not only enhance the heat dissipation performance of the device, but also further extend the overall service life of the device. In addition, installing the cooling fan 12 inside the dustproof mesh cover 11 can effectively block dust and other particles from entering the protective shell 2, preventing these pollutants from causing potential damage to the cooling fan 12. Such a design ensures that the cooling fan 12 and the entire device can operate stably and reliably, thereby greatly extending their respective service lives.

[0030] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a temperature sensor 13 is installed on one side of the protective shell 2, and the detection end of the temperature sensor 13 is inserted into the interior of the protective shell 2. A PLC controller 14 is installed on one side of the protective shell 2. The temperature sensor 13 is connected to the PLC controller 14 through a wire, and the wiring terminal of the PLC controller 14 is connected to two cooling fans 12 through a wire. Through the setting of the temperature sensor 13, the temperature change inside the device can be monitored and detected in real time. At the same time, through close cooperation with the PLC controller 14, these detected data can be fed back and processed in real time. Based on this information, the system can intelligently adjust the speed of the cooling fan 12, thereby effectively controlling and adjusting the performance of the cooling system. Such a mechanism ensures that the device can operate stably within the optimal temperature range, and significantly improves the stability and safety of the device during use.

[0031] according to Figure 2 and Figure 3 As shown, two stiffening rib frames 15 are installed on the top and bottom of the protective shell 2, and one side of the stiffening rib frame 15 is attached to one side of the low-voltage measurement and control device body 1. A plurality of second fastening bolts 16 are arranged on the outer side of each stiffening rib frame 15. Through the arrangement of the stiffening rib frame 15, it cooperates with the second fastening bolts 16, thereby significantly enhancing the connection strength between the low-voltage measurement and control device body 1 and the protective shell 2. This structural optimization ensures the tightness of the connection between the key structures of the device, thereby further improving the structural strength of the device itself and ensuring its operation stability under various working conditions.

[0032] according to Figure 1As shown, a control panel 17 is provided on the surface of the low-voltage measurement and control device body 1, a plurality of test indicator lights 18 are provided on the surface of the control panel 17, an electronic display screen 19 is provided on the surface of the control panel 17, and a plurality of control buttons 20 are provided on the surface of the control panel 17. Through the setting of the test indicator lights 18 and the electronic display screen 19, the operator can monitor the measurement and control process in real time and clearly view the relevant data information. Such a design greatly facilitates the manual operator to make judgments quickly and accurately, thereby effectively making necessary adjustments and optimizations to the low-voltage electrical equipment. In addition, through the setting of the control button 20, the user can flexibly and finely adjust the operating status of the device to ensure that the device can meet various scenarios and diversified usage requirements.

[0033] Working principle: First, connect the test circuit cable to the low-voltage measurement and control device body 1 to test whether it can operate normally. After the test is confirmed to be correct, transport the low-voltage measurement and control device body 1 to the designated location and prepare for installation.

[0034] During the installation and fixing stage, according to different installation environments, the first connecting rod 603 is moved to make the second ear seat 602 rotate inside the first ear seat 601, thereby prompting the two groups of multi-directional installation mechanisms 6 to expand to both sides respectively, prompting the installation seat 606 to fit against the wall or the designated installation area, or by moving the second connecting rod 604, the second connecting rod 604 is prompted to rotate inside the first connecting rod 603, and at the same time the third ear seat 605 drives the installation seat 606 to rotate, so that the entire multi-directional installation mechanism 6 is folded and adjusted at a certain angle, prompting the installation seat 606 to fit against the wall or the designated installation area. During the adjustment process, the anti-slip support plate 703 is always in contact with the outside of the protective shell 2, and then the first fastening bolt 607 is screwed to install and fix the low-voltage measurement and control device body 1. During the overall installation process, the damper 701 and the second spring 702 will cooperate with each other to absorb and reduce the vibration force generated during the installation process, thereby maintaining the stability of the low-voltage measurement and control device body 1 and preventing it from shaking.

[0035] During the cable plugging stage, the cables of the low-voltage electrical equipment that need to be measured and controlled are inserted into the wiring port 3 in sequence. Then, the operating hand wheel 507 is turned to cause the worm 505 to drive the worm wheel 504 and the connecting shaft 501 corresponding thereto to rotate. At the same time, the single connecting shaft 501 drives the single pulley 502 to rotate, and the rotational force is transmitted to the other pulley 502 and the connecting shaft 501 through the transmission belt 503. Under the action of the rotational force, the two screw rods 402 rotate synchronously, causing the two groups of first sliding frames 403 to drive the corresponding half-protective frames 404 to slide close to each other. In the process of approaching, the two half-protective frames 404 have opposite ends that jointly squeeze the slope angle of the trapezoidal pressing frame 409, so that the two second sliding frames 408 slide on the corresponding fixed rods 406, and squeeze the first spring 407 to shrink it. At the same time, the trapezoidal pressing frame 409 is subjected to the squeezing force to press the low-voltage electrical equipment cable connector inserted into the wiring port 3. Finally, the two wire management slots 405 are merged, and the cables are sequentially inserted into the corresponding wire management slots 405.

[0036] During the operation stage of the device, the low-voltage measurement and control device body 1 is started by pressing the control button 20, and the low-voltage measurement and control device body 1 is adjusted according to the actual measurement and control needs. The measurement and control process and parameters will be displayed through the test indicator light 18 and the electronic display screen 19, which is convenient for the operator to read the parameters and adjust the low-voltage electrical equipment under measurement and control. At the same time, the temperature sensor 13 monitors the temperature changes inside the protective shell 2 in real time, and transmits the monitoring data to the PLC controller 14. The PLC controller 14 analyzes and processes the data, controls the two cooling fans 12 to adjust the speed, adjusts the stable heat dissipation for the low-voltage measurement and control device body 1, and keeps the low-voltage measurement and control device body 1 in a relatively stable operating state at all times.
