Abstract
The utility model relates to a resistance strain pressure axial type soil pressure cell, which consists of a cell body, a cell cover, a resistance strain film and a collecting plate; wherein, the waterproof sealing glue is filled in the cell body. The utility model is characterized in that: a ring groove (10) is provided in the cell body (1), which forms a ring elastic membrane (11); the resistance strain film (3) is coated on the elastic membrane (11); a loading plate (5) is connected and provided on the outer side of the cell body (1) and the inner side of the loading plate (5) clearance fits the outer side of the cell body (1). The utility model has simple structure and has the capability of impacting resistance pressure and overloading resistance pressure.
Description
Technical field
The utility model relates to pressure-detecting device, especially for the basis as the roadbed pressure detection.
Background technology
Existing diaphragm type resistance-strain type soil pressure cell includes box body, lid, and the middle part in box body has concave surface and forms flexible sheet, is covered with resistance strain gage on this flexible sheet, and terminal block also is housed in box body, and is filled with sealing glue formation in box.Its shortcoming is only to be fit to static row usefulness, and presses in using and do when excessive, makes flexible sheet generation permanent deformation easily and destroyed.Particularly when dynamically having surge pressure to use, as be used for roadbed and detect, as vehicle by the time roadbed produce surge pressure, pressure heightens rapidly, it is irrecoverable and scrap to make flexible sheet easily transship the generation permanent deformation.
Summary of the invention
The purpose of this utility model is to improve at the shortcoming deficiency of prior art, provides a kind of simple in structure, and adaptability is strong, anti-overload, shock resistance, the resistance-strain soil pressure cell of suitable quiet dynamic use.
The utility model includes box body, lid, setting and is installed in resistance strain gage, terminal block in the box body, is filled with anti-water seal glue in box body.It is characterized in that in box body 1, offering annular groove 10 and form cyclic spring diaphragm 11, on groove 10 internal dielectric membrane sheets 11, be covered with resistance strain gage 3, middle side part is provided with and connects boss 4 and be connected the loading plate 5 that boss 4 secure fit connect with this outside box body 1, loading plate 5 inboards are clearance fit with box body 1 outside, are provided with elastic sealing strip 6 at the outer shroud place of box body 1 and loading plate 5
The utility model is simple in structure, it is stressed that its cyclic spring diaphragm 11 and loading plate 5 structures that are provided with form pressing shaft type, work as the pressure overload during use, loading plate 5 inboards recline with box body 1 outside, make flexible sheet 11 and on resistance strain gage not at stress deformation, have Antiimpact pressure and anti-overload capacity completely, so can not cause overload and surge pressure to damage.Be not only applicable to static pressure and detect use, and be particularly suitable for highway, railway bed etc. and have surge pressure effect occasion to use.
Description of drawings
Accompanying drawing is the utility model example structure synoptic diagram.
