Utility model content
The purpose of this utility model be to provide a kind of without wearing and tearing, not temperature influence, precision is high, unit area weighs greatly, reliability is high, without component ageing, structure is simple, volume is little, price is low ground weighing instrument.
Technical solution of the present utility model is:
A kind of adhering film many bellows ground scale, comprise film capsule, a tensimeter that two stiffener plate one of upper and lower parallel placement and stiffener plate two, two or more are made with the impermeable flexible material not easily extended, film and two stiffener plate two faces in opposite directions together constitute an enclosure space, liquid is filled with in enclosure space, tensimeter is communicated with this enclosure space, and enclosure space is pie; Film capsule is bonding with stiffener plate one, stiffener plate two respectively, or film capsule only contacts with stiffener plate one, stiffener plate two respectively.
Further, the Euler characteristic of this enclosure space and the identical of sphere.
Further, on the forward surface of stiffener plate one or stiffener plate two, total at least three boss structures limit the relative displacement of two stiffener plate.
Further, boss structure specifically comprises: a macropore in stiffener plate one or stiffener plate two, one piece of diameter is greater than macropore and has the plate of an aperture, stiffener plate one or stiffener plate two are provided with a screw, a diameter is less than the bolt of aperture through aperture, bolt is movably connected in stiffener plate one, stiffener plate two respectively, and the end of bolt is greater than aperture and is less than macropore.
The beneficial effects of the utility model are: without wearing and tearing, without component ageing, not temperature influence, unit area weighs greatly, precision is high, reliability is high, volume is little, highly low, structure is simple, price is low advantage.

Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
This kind of adhering film many bellows ground scale, comprise two parallel up and down stiffener plate 1 and stiffener plate 22, the film capsule 3 that two or more is made with the impermeable flexible material not easily extended, a tensimeter 4, as Fig. 4, film capsule 3 is between two stiffener plate two face A1 and B1 in opposite directions, and three together constitutes an enclosure space, be filled with liquid at this enclosure space, tensimeter 4 is communicated with it.
Can be more specifically that two stiffener plate 1 and the common steel plate of stiffener plate 22 make, and the fluid-tight chemical fabric of film capsule 3 makes, and film capsule 3 is placed between two stiffener plate, connects with bonding or flange 5, screw 6.Film capsule 3 is bonding with stiffener plate 1, stiffener plate 22 respectively, or film capsule 3 only contacts with stiffener plate 1, stiffener plate 22 and do not fix respectively.
Fig. 1 realizes connecting of film capsule 3 and stiffener plate by bonding method, and in Fig. 1, the middle part of film capsule 3 and two stiffener plate 1, stiffener plate 22 are bonding, and the remainder of film capsule 3 is not bonding with stiffener plate 1, stiffener plate 22.Fig. 2 realizes connecting of film capsule 3 and stiffener plate with flange 5 and screw 6.
When stiffener plate is stressed, will produce certain pressure in enclosure space, tensimeter 4 illustrates stressed size by measuring pressure gauge.Enclosure space is pie.The cross section of film capsule 3 outward flange and stiffener plate not contact position is the semicircle of radius=R.If pressure=P, then drawing stress=P × the R of this place's film.The stress at other place of film is less.Find out thus, as long as R is enough little, the stress of film is just enough little.For this reason, need the distance of A1 and stiffener plate 2 21 enough little, also require that the area of A1 and stiffener plate 2 21 is enough large, film is only contacted with A1 and B1 face.
Its principle is: be directly proportional to the radius-of-curvature of this part to the stress of the stiffener plate not membraneous material of contact position, the stress of other parts is less.When stiffener plate 1 and the distance of stiffener plate 22 are less, radius-of-curvature is also less.Thus as long as stiffener plate 1 is enough little with the distance of stiffener plate 22, film just can produce enough large pressure.
The intensity of existing chemical fabric can fully meet R=0.01 rice, the requirement of P=2MP.This is equivalent to the unit area bearing capacity of 200t/m, and this is more than sufficient for general weighing.
For improving measuring accuracy, the reading of tensimeter 4 is demarcated by actual measured value.Because the bending resistance of film is very little, therefore the measuring error caused due to the deadlock of film is very little.
For preventing overload and conveniently moving, at A1 or/and B1 face is provided with at least three boss structures.
Boss structure is, as Fig. 3: bore a macropore C in stiffener plate 1 or stiffener plate 22, one piece of diameter is greater than C and has the platelet of an aperture D to be connected on A1 or B1, in stiffener plate 22 or stiffener plate 1, a screw is made corresponding to D, the bolt 7 that diameter is less than D is fixed in stiffener plate 22 or stiffener plate 1 through D, the end of bolt 7 is greater than D and is less than C, and bolt 7 only limits the excessive relative displacement of two stiffener plate.
Multiple film capsule 3 ground scale is simultaneously for weighing, and as Fig. 4, the stiffener plate being wherein placed on ground connects as one.The stiffener plate on top also connects as one.Can also by the stiffener plate of firm replacement bottom, ground.
