Description
Technical field
The utility model relates to a kind of measuring equipment, particularly relates to a kind of device for pressure measurement.
Background technology
More and more outstanding in the demand of each industrial circle to pressure test such as metallurgy, mine, papermaking, printing, transports.Such as, measure roll-force, the tension force of steel band, the tension force of paper of steel rolling, the automatic measurement of crane extract, the weighing of batching, the cutting force of metal cutting process and elevator safety protection etc.
Current existing device for pressure measurement, because complex structure, overload performance are poor, less stable in rugged surroundings, cannot meet modern industry measurement requirement.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of output power is large, antijamming capability is strong, overload performance is good, structure and circuit simple, can work in the presence of a harsh environment, device for pressure measurement that the life-span is long.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of device for pressure measurement, comprise base, described base is provided with measurement mechanism main body, mounting bracket is provided with in described measurement mechanism main body, described mounting bracket bottom is provided with the first mounting structure, described mounting bracket top is provided with the second mounting structure, between described first mounting structure and the second mounting structure, piezomagnetic element is installed, symmetrical elastic support is provided with above described mounting bracket, steel ball mounting groove is provided with above described symmetrical elastic support, in described steel ball mounting groove, power transmission steel ball is installed.
When measurand applies pressure to power transmission steel ball, described symmetrical elastic support becomes the first pressure buffer body, and pressure will be weakened pass to mounting bracket, described mounting bracket becomes the second pressure buffer body, and less pressure sensitive is passed to piezomagnetic element, described piezomagnetic element produces deformation, and electromagnetism rate changes, thus change piezomagnetic element magnetic resistance, realize the conversion of pressure and electric signal.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described base is solid cylindrical discus, for increasing the gravity of device for pressure measurement, reduces rocking of device itself.
Further, described measurement mechanism main body is rustless steel material, because rustless steel material ability of anti-deformation is strong, is conducive to the overload performance increasing device for pressure measurement.
Further, described first mounting structure and the second mounting structure symmetry are installed, to ensure that power transmission steel ball center of gravity and piezomagnetic element center of gravity are on same straight line.
Further, described piezomagnetic element is provided with lead-in wire, for the output of electric signal.
The beneficial effects of the utility model are: output power is large, antijamming capability is strong, overload performance is good, structure and circuit simple, can work in the presence of a harsh environment, the life-span is long.
Accompanying drawing explanation

In accompanying drawing, the list of parts representated by each label is as follows: 1, base, and 2, measurement mechanism main body, the 3, first mounting structure, 4, piezomagnetic element, 5, mounting bracket, the 6, second mounting structure, 7, symmetrical elastic support, 8, power transmission steel ball, 9, steel ball mounting groove, 10, lead-in wire.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of device for pressure measurement, comprise base 1, described base 1 is provided with measurement mechanism main body 2, mounting bracket 5 is provided with in described measurement mechanism main body 2, described mounting bracket 5 bottom is provided with the first mounting structure 3, described mounting bracket 5 top is provided with the second mounting structure 6, between described first mounting structure 3 and the second mounting structure 6, piezomagnetic element 4 is installed, symmetrical elastic support 7 is provided with above described mounting bracket 5, steel ball mounting groove 9 is provided with above described symmetrical elastic support 7, in described steel ball mounting groove 9, power transmission steel ball 8 is installed.
When measurand applies pressure to power transmission steel ball 8, described symmetrical elastic support 7 becomes the first pressure buffer body, and pressure will be weakened pass to mounting bracket 5, described mounting bracket 5 becomes the second pressure buffer body, and less pressure sensitive is passed to piezomagnetic element 4, described piezomagnetic element 4 produces deformation, and electromagnetism rate changes, thus change piezomagnetic element 4 magnetic resistance, realize the conversion of pressure and electric signal.
Described base 1 is solid cylindrical discus, for increasing the gravity of device for pressure measurement, reduces rocking of device itself; Described measurement mechanism main body 2 is rustless steel material, because rustless steel material ability of anti-deformation is strong, is conducive to the overload performance increasing device for pressure measurement; Described first mounting structure 3 and the second mounting structure 6 symmetry are installed, to ensure that power transmission steel ball 8 center of gravity and piezomagnetic element 4 center of gravity are on same straight line; Described piezomagnetic element 4 is provided with lead-in wire 10, for the output of electric signal.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
