Abstract
The utility model discloses an earth pressure sensor comprising elements such as a push plate and the like. The push plate is connected with a body through a first O-shaped ring; a steel ball is inserted in a hole of the body; a nozzle is arranged in the body; a second O-shaped ring is fixed at one side of a diffused silicon core; the diffused silicon core, a compression cap, a circuit compensation plate and an amplification circuit board are sequentially arranged in the nozzle; the circuit compensation plate is fixed with the compression cap through a cross recess head screw and a retainer ring; the cross recess head screw penetrates through the retainer ring; a protection cover is welded with the external part of the body; one end of a silicon rubber connection lead is connected with the amplification circuit, and the other end of the silicon rubber connection lead is connected with a four-core pin; a third O-shaped ring is arranged between the upper cover of the pin and the nozzle; and an upper cover is also clamped between the upper cover of the pin and the nozzle. In the earth pressure sensor, elements such as the upper cover, the four-core pin and the like can be screwed off for data adjustment as requirement, so that the operation is convenient.
Description
Technical field
The utility model relates to a kind of sensor, particularly a kind of soil pressure case.
Background technology
It all is in the interior accent that existing sensors one is removed, just no longer adjust after just configuring data, just can not be completed if meet when needing the adjustment data.
The utility model content
The utility model technical matters to be solved provides a kind of soil pressure case, and it can back out element adjustment data such as loam cake and four-core plug-in unit as required.
For solveing the technical problem; The utility model provides a kind of soil pressure case, it is characterized in that, it comprises that push pedal, an O type circle, steel ball, pressure inlet, body, the 2nd O type circle, diffuse si core body, clamping cap, back-up ring, Cross Recess Head Screw, circuit compensation plate, protective cover, magnification circuit plate, silicon rubber connect lead, plug-in unit loam cake, four-core plug-in unit, the 3rd O type circle and loam cake; Push pedal is connected with body through an O type circle; Steel ball is inserted in the hole of body, and pressure inlet is located at the inside of body, and the 2nd O type circle is fixed on a side of diffuse si core body; Diffuse si core body, clamping cap, circuit compensation plate, magnification circuit plate are located in the pressure inlet successively; The circuit compensation plate is fixed through Cross Recess Head Screw, back-up ring and clamping cap, and Cross Recess Head Screw passes back-up ring, the outside weldings of protective cover and body; The end that silicon rubber connects lead is connected with magnification circuit plate; The other end that silicon rubber connects lead is connected with the four-core plug-in unit, and the 3rd O type circle is located between plug-in unit loam cake and the pressure inlet, and loam cake is stuck on plug-in unit loam cake and the pressure inlet simultaneously.
The positive progressive effect of the utility model is: the utility model can be backed out element adjustment data such as loam cake and four-core plug-in unit, handled easily as required.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of the utility model soil pressure case.
Fig. 2 is the structural representation after the utility model soil pressure case assembling.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As depicted in figs. 1 and 2; The utility model soil pressure case comprises that push pedal 1, an O type circle 2, steel ball 3, pressure inlet 4, body 5, the 2nd O type circle 6, diffuse si core body 7, clamping cap 8, back-up ring 9, Cross Recess Head Screw 10, circuit compensation plate 11, protective cover 12, magnification circuit plate 13, silicon rubber connect lead 14, plug-in unit loam cake 15, four-core plug-in unit 16, the 3rd O type circle 17 and loam cake 18; Push pedal 1 is connected with body 5 through an O type circle 2; Steel ball 3 is inserted in the hole of body 5, and pressure inlet 4 is located at the inside of body 5, and the 2nd O type circle 6 is fixed on a side of diffuse si core body 7; Diffuse si core body 7, clamping cap 8, circuit compensation plate 11, magnification circuit plate 13 are located in the pressure inlet 4 successively; Circuit compensation plate 11 is fixing with clamping cap 8 through Cross Recess Head Screw 10, back-up ring 9, and Cross Recess Head Screw 10 passes back-up ring 9, the outside weldings of protective cover 12 and body 5; The end that silicon rubber connects lead 14 is connected with magnification circuit plate 13; The other end that silicon rubber connects lead 14 is connected with four-core plug-in unit 16, and the 3rd O type circle 17 is located between plug-in unit loam cake 15 and the pressure inlet 4, and loam cake 18 is stuck on plug-in unit loam cake 15 and the pressure inlet 4 simultaneously.
When the utility model soil pressure case need be adjusted data, can back out elements such as loam cake and four-core plug-in unit and adjust handled easily.The utility model soil pressure case also has three O type circle sealings, and the loam cake after tightening can effectively be prevented bleeding of sealing.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
