Description

Fixed limit structure of fluid medium pressure gauge Technical Field The utility model relates to the technical field of pressure gauges, in particular to a fixed limiting structure of a fluid medium pressure gauge. Background The fluid pressure gauge is a meter which takes an elastic element as a sensitive element and measures and indicates pressure higher than ambient pressure, is very popular in application, and is increasingly widely applied in the industrial process control and technical measurement process due to the characteristics of high mechanical strength, convenient production and the like of the elastic sensitive element of the mechanical pressure gauge. In the installation process of the fluid medium pressure gauge, an installation limiting structure is required to be adopted for installation, the traditional installation is mainly carried out by adopting a flange for fixed installation, but the phenomenon of unstable installation and fixation exists in the installation process of the flange, and a good limiting effect cannot be formed. Disclosure of utility model The utility model aims to provide a fixed limiting structure of a fluid medium pressure gauge, which aims to solve the problems in the background technology. The fixed limiting structure comprises a flange mounting seat, a flange neck and a pressure gauge connecting section, wherein the middle part of one end face of the flange mounting seat is integrally formed with the flange neck, one end of the pressure gauge connecting section is integrally formed at an opening part of the flange neck, the fixed limiting structure further comprises a limiting connecting assembly, the limiting connecting assembly comprises two L-shaped connecting frames, two lug limiting parts, 匚 -shaped limiting frames and two step connecting parts, one end of each L-shaped connecting frame is provided with a fastening stud, the L-shaped connecting frames are connected with mounting holes of the flange mounting seat through the fastening studs, the two step connecting parts are arranged at the other end of the corresponding L-shaped connecting frames, one end of each step connecting part is integrally formed with one end of each lug limiting part, and flange clamping step parts are formed at step positions of the two step connecting parts. In the fluid medium pressure gauge with the rapid disassembly and assembly structure, the two ends of the 匚 type limiting frame are provided with the bolt posts, and the two bolt posts are spliced with the corresponding lug plate limiting parts. In the fluid medium pressure gauge with the rapid disassembly and assembly structure, a clamping block mounting groove is formed in the middle of the top end of the 匚 -type limiting frame, and a corner-type clamping block is movably connected in the clamping block mounting groove. In the fluid medium pressure gauge with the rapid disassembly and assembly structure, the two round holes of the flange mounting seat are provided with the set screws, and the spiral length of the two set screws is not lower than the thickness of the flange mounting seat. In the fluid medium pressure gauge with the rapid disassembly and assembly structure, the sealing connecting ring is arranged at the center of the other end face of the flange mounting seat. In the fluid medium pressure gauge with the rapid disassembly and assembly structure, the fluorine rubber sealing ring of the connecting flange mounting seat is arranged at the outer ring of the sealing connecting ring. The utility model has the technical effects and advantages that: The fixed limiting structure of the fluid medium pressure gauge comprises two L-shaped connecting frames, two lug plate limiting parts, 匚 -shaped limiting frames, two step connecting parts and the like, and a flange clamping step part is formed at the step position of the step connecting parts, so that a flange and a flange mounting seat are conveniently and well limited, the connection firmness and stability between the flange and the flange mounting seat are ensured, and meanwhile, the fixed limiting structure has a good dismounting effect and is convenient for rapid assembly.
