The utility model is low for gauge measurement precision traditional in prior art, cost is high, the shortcomings such as display and use inconvenience, provide a kind of by arranging hinge spring on gear drive, improve manometric measurement precision, filling methyl-silicone oil in watchcase can resist working environment to vibrate pulsations affect that is more acute and less pressure medium, improves and measures precision.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Bellows shock-proof pressure gauge, comprise watchcase to enclose with cover, cover circle kayser is on watchcase, watchcase lower end is fixedly connected with joint, and arrange bellows and hinge spring in watchcase, bellows is connected with gear drive, hinge spring is set on gear drive, gear drive is connected with the pointer that dial plate is arranged, and watchcase top arranges button, and joint comprises adapter body and connection end.Hinge spring one end is connected with joint, and one end is connected with pull bar.Under the pressure effect of measured medium, the end of hinge spring is forced to produce corresponding elastic deformation---displacement, give amplification by means of pull bar through the transmission of gear drive, indicated on scale by by measured value by the pointer being fixed on gear shaft.
As preferably, adapter body arranges main aperture, connection end arranges secondary aperture, main aperture communicates with secondary aperture.
As preferably, hinge spring comprise annular row around stretch section, the two ends of stretch section connect the first linkage section and the second linkage section respectively.
As preferably, between cover circle and watchcase, O-ring seal is set and is tightly connected.
As preferably, gear drive comprises driving lever and gear shaft, and bellows is connected with driving lever, and gear shaft is connected with pointer.
As preferably, dial plate arranges zeroing, zeroing is connected with pointer.
As preferably, bellows comprises the monolithic of two thickness 0.052mm by accurate Plasma Welding, and the diameter of bellows is 100mm.
As preferably, in watchcase, fill methyl-silicone oil or glycerine.
The utility model is owing to have employed above technical scheme, there is significant technique effect: the utility model by arranging hinge spring on gear drive, improve manometric measurement precision, filling methyl-silicone oil in watchcase can resist working environment to vibrate pulsations affect that is more acute and less pressure medium, improves and measures precision.
