[0028] In the present invention, the shell 1 is used as the main body of the device. First, the position of the mounting ear plate 2 is adjusted according to the installation position, the clamping mechanism 3 is pulled out from the inside of one positioning groove 5, and then rotated to the other end along the inside of the arc groove 4 and plugged into the inside of another positioning groove 5, and slid through the arc groove 4 to rotate the mounting ear plate 2 ninety degrees. When the mounting ear plate 2 is adjusted to be parallel to the back of the shell 1, the back is installed close to the object. When the mounting ear plate 2 is adjusted to be parallel to the top of the shell 1, the top is installed close to the object. According to the different installation angles of the mounting ear plate 2, the terminal block 7 can be rotated in advance to adjust the direction of the multi-signal wiring port group 8, so that the multi-signal wiring port group 8 is always facing upward, which is convenient for wiring operation. The structure is flexible and practical, and the heat generated by the NB-loT communication module 9 during the operation of the device is passed through The heat-conducting and heat-dissipating component 10 conducts heat and blows it out through two ventilation holes 11, and the heat dissipation channel is completely isolated from the internal electronic components. Based on the low heat generation, sealed heat dissipation is achieved, which not only ensures the internal heat dissipation requirements, but also achieves complete internal sealing, so that the device has a flexible installation structure, which is more convenient for installation in different usage environments, and achieves sealed heat dissipation, which can not only meet the heat dissipation requirements, but also ensure the advantages of sealing the internal electronic components. This solves the problem that there are more and more installation environments in the prior art, while the ear plate structure is fixed and single and cannot be flexibly adapted to various installation environments. At the same time, current heat dissipation generally relies on fans for air cooling, but the cold air is connected to the internal electronic components, and dust prevention is difficult to ensure, which reduces the service life of the internal electronic components.
