Description
Technical field
The present invention is relevant with pressure gauge, more detailed is meant a kind of pressure gauge that utilizes mechanical physical deformation to convert the numeral demonstration into.
Background technology
The pressure gauge 1 of general traditional mechanical formula, as shown in Figure 1, mainly be that Baden pipe 12, connecting rod 13, sector gear 14, pinion wheel 15, volute spring 16 and pointer 17 are set in a housing 11; When making in Baden's pipe 12 that gas or liquid when high pressure is directed in this pressure gauge 1, this Baden's pipe 12 can produce distortion according to the size of pressure, and its deflection also transmits and spurs this sector gear 14 via connecting rod 13; Make the amplitude of oscillation drive the rotation that pinion wheel 15 is made relative quantity by sector gear 14; Pinion wheel 15 is coaxial with pointer 17, makes pointer 17 be able to do the rotation indication of same amount, and can be by the indication of visual observation pointer 17; Scale outside the cooperation housing 11 is with the decompression force size; And when pressure disappears, 16 elastic recovery original states of this volute spring, and pointer 17, pinion wheel 15 driven by axle simultaneously and make zero.
Though suitable cheap of above-mentioned mechanical pressure gauge 1 cost; But its pointer displayed 17 must cooperate scale; Therefore not only between scale, have fuzzy region, cause observation to be difficult for, even can only be with the mode rough estimate force value of conjecture; Therefore at accuracy of using and the convenience of observing, all still have sizable progressive space.
In addition; A kind of pressure gauge 2 of digital electronic formula is arranged, and as shown in Figure 2, this pressure gauge 2 mainly is provided with a pressure inductor 22 in a housing 21; One battery 23, an electronic circuit board 24 and a LCD Panel 25; With pressure, and be sent to electronic circuit board 24, and convert numeric data into via this electronic circuit board 24 with signal by these pressure inductor 22 sensing gases at high pressure or liquid; And on this LCD Panel 25, manifest, 23 on this battery is in order to supply this pressure inductor 22, electronic circuit board 24 electric power with LCD Panel 25.
The pressure gauge 2 of the above-mentioned digital electronic formula that discloses; Check quite easily and identification though change by the numerical value demonstration; But because the manufacturing technology of the key part and component of this pressure inductor 22 is grasped in specific manufacturer; Cause suitable high of the acquisition cost of pressure inductor 22, its cost changes valency when the consumer goes up, and will certainly let the consumer step back.
Secondly, have a kind of principle of induction of utilizing to convert mechanical drive principle into pressure gauge 3 that numeral shows at present on the market, as shown in Figure 3, and this pressure gauge 3 also this case applicant is previous had just applied for, and the patent right of getting permission through substantive examination.Wherein, This pressure gauge 3 consists predominantly of Baden pipe 31, connecting rod 32, sector gear 33, pinion wheel 34, volute spring 35, electronic circuit board 36, LCD Panel 37, battery 38, CD 391 and light sensor 392; When the air pressure of high pressure or liquid are directed in this Baden's pipe 31; This Baden's pipe 31 is to produce big small deformation according to pressure; Make by its deflection and spur sector gear 33 via these connecting rod 32 transmission, make the amplitude of oscillation be able to drive the rotation that pinion wheel 34 is made relative quantity by sector gear 33; And pinion wheel 34 is coaxial with CD 391, makes CD 391 also do the rotation of same amount, via the induction of this light sensor 392; And transmission signal to electronic circuit board 36, and by these electronic circuit board 36 transforming numerical data display digit on LCD Panel 37.
Since above-mentioned gases at high pressure or liquid are directed in Baden's pipe 31 to CD 391 produce action before, belong to mechanical drive, CD 391 and light sensor 392 then symbolic animal of the birth year when known and skillful technology.Therefore, this kind utilizes principle of induction to convert mechanical drive principle into pressure gauge 3 that numeral shows, shows that compared to complete numeral with the electronics start pressure gauge will come cheap manyly, and possesses the competitive power on the market.But,, therefore on cost, still have the space of improvement because its member is numerous.
