Abstract

The invention discloses a soil pressure sensor which comprises elements such as a push plate. The push plate is connected with a probe through a first O-shaped ring, a diffusion silicon core and a pressure cap are arranged in the probe, a second O-shaped ring is arranged on the outer periphery of the probe, and a circuit compensating plate is fixed with the pressure cap through a first screw and a first retainer ring. One end of a silicon rubber connection wire is connected with the circuit compensating plate while the other end of the silicon rubber connection wire is connected with an amplifying circuit. A shell is welded with the probe, the amplifying circuit is fixed to a pressure wire upper cover through a second retainer ring and a second screw, a sealing gasket is arranged between the pressure wire upper cover and the wire, a washer is arranged between the sealing gasket and a pressure wire nut, a third screw is fixed onto the pressure wire upper cover, and a steel ball is arranged in the probe and close to one side of the push plate. Elements such as the screws, the pressure wire nut and the pressure wire upper cover can be taken down for data adjustment.

Description

Soil pressure case

Technical field

The present invention relates to a kind of sensor, particularly a kind of soil pressure case.

Background technology

It all is in the interior accent that existing sensor one is removed, just no longer adjust after namely setting data, just can not be completed if meet when needing to adjust data.

Summary of the invention

Technical matters to be solved by this invention provides a kind of soil pressure case, and it can take off as required the elements such as screw, line ball nut, line ball loam cake and adjust data.

For solveing the technical problem, the invention provides a kind of soil pressure case, it is characterized in that, it comprises push pedal, the one O type circle, probe, the diffuse si core body, clamping cap, the 2nd O type circle, the first screw, the first back-up ring, the circuit compensation plate, silicon rubber connects wire, shell, magnification circuit plate, the second back-up ring, the second screw, the line ball loam cake, sealing gasket, pad, the line ball nut, wire, the 3rd screw, steel ball, push pedal is connected with probe by an O type circle, the diffuse si core body, clamping cap is located in the probe, the 2nd O type circle is located at the periphery of probe, the circuit compensation plate is by the first screw, the first back-up ring and clamping cap are fixed, the end that silicon rubber connects wire is connected with the circuit compensation plate, the other end that silicon rubber connects wire is connected with magnification circuit plate, shell and probe welding, magnification circuit plate is by the second back-up ring, the second screw and line ball loam cake are fixed, sealing gasket is located between line ball loam cake and the wire, pad is located between sealing gasket and the line ball nut, the 3rd screw is fixed on the line ball and covers, and steel ball is located in the probe and a side of close push pedal.

Positive progressive effect of the present invention is: the present invention can take off as required the elements such as screw, line ball nut, line ball loam cake and adjust data, handled easily.

Description of drawings

Fig. 1 is the structural representation of soil pressure case of the present invention.

Embodiment

The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.

As shown in Figure 1, soil pressure case of the present invention comprises push pedal 1, the one O type circle 2, probe 3, diffuse si core body 4, clamping cap 5, the 2nd O type circle 6, the first screw 7, the first back-up ring 8, circuit compensation plate 9, silicon rubber connects wire 10, shell 11, magnification circuit plate 12, the second back-up ring 13, the second screw 15, line ball loam cake 16, sealing gasket 17, pad 18, line ball nut 19, wire 20, the 3rd screw 21, steel ball 22, push pedal 1 is connected with probe 3 by an O type circle 2, diffuse si core body 4, clamping cap 5 is located in the probe 3, the 2nd O type circle 6 is located at the periphery of probe 3, circuit compensation plate 9 is by the first screw 7, the first back-up ring 8 is fixing with clamping cap 5, the end that silicon rubber connects wire 10 is connected with circuit compensation plate 9, the other end that silicon rubber connects wire 10 is connected with magnification circuit plate 12, shell 11 and probe 3 welding, magnification circuit plate 12 is by the second back-up ring 13, the second screw 15 is fixing with line ball loam cake 16, sealing gasket 17 is located between line ball loam cake 16 and the wire 20, pad 18 is located between sealing gasket 17 and the line ball nut 19, the 3rd screw 21 is fixed on the line ball loam cake 16, and steel ball 22 is located in the probe 3 and a side of close push pedal 1.The first screw 7, the second screw 15, the 3rd screw 21 all are Cross Recess Head Screw.

When soil pressure case of the present invention need to be adjusted data, can take off the elements such as screw, line ball nut, line ball loam cake and adjust handled easily.Soil pressure case of the present invention also has the sealing of O type circle, can effectively prevent bleeding of sealing.

Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
