Description
Technical field
The present invention relates to a kind of tensimeter, be specifically related to a kind of hydraulic pressure table.
Background technology
It is sensitive element that tensimeter refers to flexible member, measures and indicates the instrument higher than environmental pressure, and application is very general, and it is almost throughout all industrial flows and scientific research field.Be seen everywhere in fields such as heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shops, especially in industrial stokehold and commercial measurement process, elastic sensing element due to mechanical compression table has very high physical strength and the characteristic such as convenient for production, makes mechanical compression table obtain applying more and more widely.
The Chinese patent patent No. is CN201410344095.9, disclose a kind of tensimeter, comprise watchcase, index dial, pointer and transformational structure, transformational structure comprises drive link, axial constraint also can rotate around own axes in watchcase, and drive link is provided with transmission external thread, and the upper end of pointer and drive link is fixed; Retainer, to be arranged in watchcase and can to move up and down, retainer can under air pressure drives on move, retainer has bullport, and drive link is located in bullport, and the hole wall of bullport is provided with the transmission internal thread coordinated with transmission external thread; Support spring, acts on retainer and makes retainer keep moving down trend.The tensimeter of this structure, although structure is simple, but when processing drive link, make it can constrain in watchcase and can rotate around own axes, must special processing be needed, or manufacture more multi-part to ensure its function, and in the process of processing bullport and screw thread, processed complex, produces difficulty, adds production cost.
Summary of the invention
The object of the present invention is to provide the hydraulic pressure table that a kind of structure is simple, reduce production cost.
Technical scheme of the present invention is: hydraulic pressure table, comprise hollow tube, hydraulic oil is provided with in described hollow tube, slidably connect piston in first cavity of hollow tube one end, described piston is connected with manometric import, slidably connects tooth bar in the second cavity of the hollow tube other end, described tooth bar is provided with fixed bar away from the side of the second cavity, be connected with spring between tooth bar and fixed bar, tooth bar is engaged with gear, and gear is fixedly connected with pointer.
Beneficial effect of the present invention is: medium enters in tensimeter by manometric import, the pressure of medium is applied on piston, piston setting in motion, presses hydraulic oil and moves out in the first cavity, and at hollow Bottomhole pressure, flow to and be provided with in the second cavity of tooth bar, and press tooth bar motion, now fixed bar is motionless, spring is in compression or extended state, driven gear moves by tooth bar, gear driven hand motion, thus measures the pressure size of measured medium.
When measured medium pressure reduces, piston will do the motion in direction contrary to the above in the first cavity, now spring stress reduces, spring will resilience, promote or pull tooth bar to move, tooth bar promotes hydraulic oil and flows in hollow tube in the second cavity, and flows in the first cavity, meanwhile rack drives gear movement, thus measure the pressure after pressure reduces.
Compared with prior art, the gear train of whole device is formed primarily of rack and pinion, by hydraulic oil transmission of pressure, the elastic force of spring, convert pumping of tooth bar the rotation of gear to, structure is simple, matching relationship is few, and very common with upper-part, easy processing and fabricating, and use general, without the need to carrying out special facture or making more parts, also without the need to carrying out the processing of perforate and making screw thread, thus decreasing the Production Time of manometric gear train, decreasing manometric cost of manufacture.
Further: hydraulic oil is the machine butter of vaseline or food apparatus class.When operating personnel change cryoprotective substance, the skin of operating personnel likely directly contacts cryoprotective substance, selects vaseline or butter all can not damage the skin of people, ensure that safety.
Further: between piston and hollow tube wall and between tooth bar and hollow tube wall, to be equipped with O-ring seal.The setting of O-ring seal, can avoid hydraulic oil to flow out from hollow tube, ensure that the normal use of hydraulic oil, thus ensure that the accuracy of gauge measurement.
Further: the size of the first cavity is greater than the size of the second cavity.The setting of size, can make the distance that piston movement is less, and presses less hydraulic oil, makes the distance that the motion of the tooth bar in the second cavity is longer, thus the angle making pinion rotation larger, thus manometric precision can be made better.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hydraulic pressure table embodiment one of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: piston 1, butter 2, hollow tube 3, tooth bar 4, gear 5, O-ring seal 6, spring 7, fixed bar 8, first cavity 9, second cavity 10.
Embodiment is substantially as shown in Figure 1: hydraulic pressure table, comprise hollow tube 3, hollow tube 3 is arc hollow pipe 3, butter 2 is provided with in described hollow tube 3, vertical piston 1 is slidably connected in first cavity 9 of hollow tube 3 one end, described piston 1 is connected with manometric import, vertical tooth bar 4 is slidably connected in second cavity 10 of hollow tube 3 other end, first cavity 9 is located at the below of the second cavity 10, the size of the first cavity 9 is greater than the size of the second cavity 10, fixed bar 8 is provided with on the downside of described tooth bar 4, spring 7 is connected with between tooth bar 4 and fixed bar 8, gear 5 is engaged with on the left of tooth bar 4, gear 5 is fixedly connected with pointer, O-ring seal 6 is equipped with between piston 1 and hollow tube 3 wall and between tooth bar 4 and hollow tube 3 wall.
Medium enters in tensimeter by manometric import, and the pressure of medium is applied on piston 1, and piston 1 starts upward sliding, press butter 2, move out in the first cavity 9, and flow in hollow tube 3, flow in the second cavity 10, and press tooth bar 4 and move downward, now fixed bar 8 is motionless, and spring 7 is in compressive state, and tooth bar 4 is by driven gear 5 clockwise movement, gear 5 drives hand motion, thus measures the pressure size of measured medium.
When measured medium pressure reduces, piston 1 will in the first cavity 9 slide downward, the now stressed reduction of spring 7, spring 7 will resilience, promote tooth bar 4 to move upward, tooth bar 4 promotes hydraulic oil and flows in hollow tube 3 in the second cavity 10, and flows in the first cavity 9, meanwhile tooth bar 4 driven gear 5 moves, thus measures the pressure after pressure reduces.
When the motion of piston 1 and tooth bar 4, the setting of O-ring seal 6, can avoid hydraulic oil to flow out from hollow tube 3, ensure that the normal use of hydraulic oil, thus ensure that the accuracy of gauge measurement; The setting of the size of the first cavity 9 and the second cavity 10, piston 1 can be made to move less distance, and press less hydraulic oil, the tooth bar 4 in the second cavity 10 is moved longer distance, thus make gear 5 rotate larger angle, thus manometric precision can be made better.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in instructions etc. record the content that may be used for explaining claim.
