Abstract
The invention relates to an anti-hitting probing rod of a level switch. The anti-hitting probing rod of the level switch comprises a measuring electrode, a shielding electrode, a ground electrode and insulating layers; the measuring electrode is coaxially sleeved with the shielding electrode, and the shielding electrode is coaxially sleeved with the ground electrode; the insulating layer is arranged between the measuring electrode and the shielding electrode by sleeving, and another insulating layer sleeves the shielding electrode; a pipe sleeve coaxially sleeves the probing end of the measuring electrode; one end of a steel wire rope is fixedly mounted at the probing end of the measuring electrode in the pipe sleeve, and while the other end of the steel wire rope is coaxially sleeved with a heavy pulling object. The probing rod, by being compared with the probing rod in the prior art, has the advantages that the existing integrated type of the measuring electrode is replaced by split and flexible connecting type measuring electrode; the steel wire rope can swing toward the impacting direction of the hard object in case of being collided by the hard object, so as to avoid breaking due to direct collision with the hard object, and the anti-hitting performance of the measuring electrode is improved, and the service life is prolonged.
Description
Technical field
The invention belongs to stuff level switch field, relate to the feeler lever of stuff level switch, especially a kind of anti-fight feeler lever of stuff level switch.
Background technology
Stuff level switch (also claiming charge level limit switch) refers to whether arrive to the height of solid material in container the sensor that a certain ad-hoc location (being generally the upper limit or lower limit) detects.The contact point signal of this kind of usual output relay of sensor or open collector signal, output signal generally and drive pilot lamp, alarm or input PLC and carry out Chaining sequences control.
The feeler lever of existing stuff level switch mostly is stainless steel, and when measuring the hard object such as sandy soil, stone, easily impacted by hard object, fracture damage, and serviceable life is short.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the anti-fight feeler lever of the stuff level switch of a kind of long service life, non-frangibility is provided.
The technical scheme that technical solution problem of the present invention adopts is:
A kind of anti-fight feeler lever of stuff level switch, comprise potential electrode, guarded electrode, region and insulation course, at outer coaxial package one guarded electrode of potential electrode, at the outer coaxial package region of guarded electrode, between potential electrode and guarded electrode and guarded electrode be all set with insulation course outward, at end of probe coaxial package one pipe box of potential electrode, in pipe box, the end of probe of potential electrode is fixedly mounted with one end of a wire rope, the other end coaxial package one tractive weight of this wire rope.
And, be also set with an insulation sleeve in the junction of guarded electrode and potential electrode.
Advantage of the present invention and good effect are:
This feeler lever is with the key distinction of prior art feeler lever, potential electrode is improved to by existing integral type and is split typely flexible coupling, a tractive weight is connected by wire rope in the end of probe of potential electrode, wire rope is when running into hard object collision, can swing to the impact direction of hard object, avoid and the direct collision of hard object and fractureing, make the more resistance to impact of potential electrode, serviceable life extends.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of anti-fight feeler lever of stuff level switch, comprise potential electrode 5, guarded electrode 3, region 1 and insulation course, at outer coaxial package one guarded electrode of potential electrode, at the outer coaxial package region of guarded electrode, between potential electrode and guarded electrode and guarded electrode be all set with insulation course 2 outward.
Innovative point of the present invention is:
At end of probe coaxial package one pipe box 6 of potential electrode, in pipe box, the end of probe of potential electrode is fixedly mounted with one end of a wire rope 7, the other end coaxial package one tractive weight 8 of this wire rope.
And, be also set with an insulation sleeve 4 in the junction of guarded electrode and potential electrode.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and under the prerequisite not departing from inventive concept, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
1. the anti-fight feeler lever of a stuff level switch, comprise potential electrode, guarded electrode, region and insulation course, at outer coaxial package one guarded electrode of potential electrode, at the outer coaxial package region of guarded electrode, between potential electrode and guarded electrode and guarded electrode be all set with insulation course outward, it is characterized in that: at end of probe coaxial package one pipe box of potential electrode, in pipe box, the end of probe of potential electrode is fixedly mounted with one end of a wire rope, the other end coaxial package one tractive weight of this wire rope.
