At the beginning of this warning device of design concept, through the extensive retrieval of the applicant of this patent, recognize OMEGA on domestic market, plum Teller-Tuo benefit, HBM, these main brand pressure and weighting transducers of prestige generation TEDEA all do not have itself: when appearance weighs inaccurate, exceed franchise value and can to report to the police this function; Substantially all without self-inspection and false alarm output function, relevant design research unit also needleless to the protection capacity of safety protection software program of this respect.
Utility model content
The purpose of this utility model is to ensure that the safe and continuous that photovoltaic glass raw material is produced is carried out, prevent feed proportioning from producing proportioning mistake, stop electronic scales to weigh to break down and but there is no Timeliness coverage and continue to weigh the generation of this hidden danger, reduce production cost, improve the market competitiveness, and the accident warning device of weighing of a kind of electronic scales proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of accident warning device of weighing of electronic scales, comprise scale frame, described scale frame is connected scale body, also by web member Bonding pressure sensor on scale frame, described pressure transducer coordinates with the pressure sensitive of scale frame, it is characterized in that: on described scale frame, also connect a fixed head, described fixed head connects a high-sensitive microswitch, described microswitch is provided with a feeler lever, the end of feeler lever is arranged on the below of described pressure transducer, and be in contact with it cooperation, described microswitch connects failure indication box by wire, failure indication box is provided with the malfunction indicator lamp corresponding with corresponding microswitch.
On the basis of technique scheme, following further technical scheme can be had:
Failure indication box is also provided with the hummer for reporting to the police.
Described fixed head is L-type plate, fixed head is respectively equipped with the adjustment hole of a pilot hole and a waist type, described microswitch is provided with fixed pin with the side of feeler lever, opposite side is provided with adjustment pin, and described fixed pin is fastened on pilot hole place, and described adjustment pin is arranged in adjustment hole.
Described microswitch also wraps up a dirt-proof boot.
Described dirt-proof boot is rubber finger sleeve.
Small-sized, Swing-Rod focused on by microswitch in type selecting, and PT value (pretravel) is less, and MD value (answer gap from) is less, and misoperation vibration resistance is good.
Described dirt-proof boot is little on the impact of microswitch acting characteristic, it can eliminate the charged position of exposing, and improves antidrip property, because switch is not waterproof sealing structure, pouring may watered by liquid such as water, use in the environment that impurity, dust are more and can play safeguard function.
The utility model has the advantage of: this device can weigh the fault of measuring and occurring in Timeliness coverage electronic scale weighing process, can effectively prevent feed proportioning from producing proportioning mistake, it is simple that it has structure, easy to maintenance, cost is low, and the feature such as be quick on the draw, result of use is good.
