Abstract
The utility model relates to a new machinery for measuring pressure. The utility model is characterized in that flexible material is adopted as sealing material, which forms a sealed pressure chamber with an integrated base 2; an elastic element for measuring is fixed above the flexible material and pushes one end of a lever mechanism to slide on a plane and drives the other end to rotate on a slide rheostat 4; when the outside pressure pushes the flexible material to move upwards, the lever mechanism 5 reads the corresponding resistance value on the slide rheostat so as to get the function of the sensor alarm. The utility model has the advantages of reliable performance, high measuring accuracy and low production cost and is particularly suitable for the application on the automobile or the marine engine.
Description
The utility model is a kind of mechanical hook-up with pressure sensing and warning function, and this device especially is useful on automobile and the marine engine and uses.
Engine oil pressure is a crucial index in the engine operating state, and engine has higher requirement to the measuring sensor sensor alarm of engine oil pressure.At present a large amount of pressure sensing alarms (as metal film chip pressure transducer) that adopt measuring accuracy, reliability, come with some shortcomings on serviceable life and manufacturing cost higher relatively.
The purpose of this utility model is to provide at above-mentioned deficiency the device of a kind of novel pressure measurement and monitoring, and very big improvement has been arranged on measuring accuracy and reliability.
The realization the technical solution of the utility model is as follows: adopt flexible material (as rubber diaphragm etc.) to become airtight pressure chamber with incorporate pedestal riveting.Measurement flexible member of flexible material upper fixed, the decrement (stroke) of flexible member (as spring, corrugated tube etc.) is directly proportional with pressure in the pressure chamber.Leverage is for turning to multiplying arrangement, and the end that bar is shouldered in the flexible material promotion slides in the plane, drives to read resistance readings when the other end rotates on slide rheostat, and the ambient pressure size is directly proportional with resistance readings, reaches the purpose of gaging pressure.
Fig. 1, Fig. 2, Fig. 3 are the structural drawing of an embodiment of the utility model.
The utility model embodiment as shown in Figure 1, rubber diaphragm 1 connects the pressure chamber that forms sealing with integrated base 2 usefulness riveting modes, pressure chamber and measured machine oil UNICOM, the upper fixed of rubber diaphragm has a measuring spring 3, when in the pressure chamber pressure source being arranged, rubber diaphragm is experienced the pressure in the pressure chamber and is promoted measuring spring and moves upward, and the stroke of measuring spring is directly proportional with the size of pressure, as shown in Figure 2, leverage 5 plays the effect that motion turns to and amplifies.This leverage becomes vertical direction to moving upward of rubber diaphragm and measuring spring and rotates, and the stroke that rotates is amplified, and a torsionspring 6 is set in the leverage, when the pressure in the pressure chamber from large to small the time, plays the effect of return.An end that promotes lever as Fig. 3 rubber diaphragm slides in the plane, drive the other end and on slide rheostat 4, rotate, pressure big or small with slide rheostat on reading corresponding one by one, reach the effect of sensing and warning.
The utility model adopts integrated pedestal to solve the problem of traditional structure leakage of oil.Good with spring and the lever gaging pressure consistance than the measuring accuracy of conventional metals diaphragm type pressure sensor and measurement on performance, this structure manufacturing cost also is significantly less than the virgin metal diaphragm type pressure sensor.Be that the utility model has a very big raising at aspect of performances such as measuring accuracy, reliability, serviceable lifes, and cheap for manufacturing cost.
Claims (5)
