[0002] A digital display instrument is an instrument used to convert analog signals in a process control system into digital displays. Compared with the pointer display instruments used earlier, digital displays have the advantages of small size, high display accuracy, and intuitive data display. Therefore, an integrated control digital display instrument is needed. Among them, the "digital display instrument" disclosed by the authorization announcement number "CN214306253U" has solved the problems that the existing digital display instruments still have certain disadvantages when in use, and do not have a protective structure. In addition, the factory environment is relatively complex, and collisions are prone to damage to the digital display instruments, which will affect the normal use of the digital display instruments. After further searching, it was found that the authorization announcement number is "CN210071224 U" disclosed "a digital display instrument that is easy to carry", through a specific technical structure setting, effectively solves the technical disadvantages of low efficiency and inconvenience in carrying after the digital display instrument is disassembled and taken to the instrument calibration room for calibration. However, in actual use, the integrated control digital display instrument with a similar structure still has many defects, such as: it does not have the function of quickly disassembling and assembling the digital display instrument inside the protective cover, which makes it inconvenient to install and disassemble the digital display instrument inside the protective cover, affecting the efficiency of the operator to disassemble and assemble the digital display instrument out of the protective cover; it does not have the function of protecting the display screen, which causes the display screen to be damaged due to external force collision, reducing the protective effect of the protective cover, so it is necessary to design an integrated control digital display instrument.
