Description
Technical field
This utility model relates to electronic crane scale technical field, is specially a kind of antioverloading electronic crane scale.
Background technology
Electronic scale is because weighing accurate, directly perceived, and it is easy to use, it is commonly utilized in various industry and field, electronic scale generally uses sensor, and when object hanging is on suspension hook, pressure is applied to sensor, sensor is made to deform upon, so that impedance changes, use driving voltage to change simultaneously, export the analogue signal of a change.The amplified circuit of this signal amplifies output and arrives analog-digital converter, and this result is exported display according to program by CPU.Pressure transducer all has a certain amount journey, it is adaptable to sensing weight weight of object in its range.If the weight of weighting objects exceedes the range of electronic scale, so can cause the malfunctioning of sensor in electronic balance or damage.
Utility model content
The purpose of this utility model is to provide a kind of antioverloading electronic crane scale, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model following technical scheme of offer: a kind of antioverloading electronic crane scale，Including casing，The left end of described casing connects display screen，The right-hand member inner chamber of described casing is provided with power supply，The intracavity bottom of described casing is provided with buzzer，The negative pole of described buzzer and the negative pole of power supply are electrical connected，The wall inner chamber of described casing is provided with wire guide，The inner chamber of described wire guide is provided with wire，The positive pole of described wire and power supply is electrical connected，The lower surface of described casing is provided with through hole，Described through hole be respectively arranged on the left side and the right side groove，Described groove inner chamber is provided with joint，Joint and wire on the right side of described through hole are electrical connected，And the joint on the left of the positive pole of described buzzer and through hole is electrical connected，The inner chamber of described through hole is provided with connecting rod，The bottom of described connecting rod connects suspension hook，The top of described connecting rod connects sensor，Described sensor is respectively and power supply、Display screen is electrically connected with，The upper end of described connecting rod is provided with conducting line segment，The left and right sides of described conducting line segment is respectively arranged with vacant joint，The top of described sensor connects upper connecting rod，The top of described upper connecting rod connects suspension ring.
Preferably, described upper connecting rod and the fixing connection of casing.
Preferably, described conducting line segment and connecting rod insulation connect.
Preferably, described vacant joint from initial condition to the maximum functional range that the distance contacted with joint is sensor.
Preferably, described buzzer and sensor are in parallel.
Compared with prior art, the beneficial effects of the utility model are: the principle of electronic crane scale is to be applied pressure to sensor by weighting objects, sensor is made to deform upon, then through a series of processing of circuit, finally shown corresponding result by display screen, but sensor has certain deformation limit, if the weight of weighting objects exceedes the range of electronic scale, so can cause the malfunctioning of sensor in electronic balance or damage.But current electronic crane scale scarcely has overload protective device, or antioverloading is inconspicuous, compared with prior art, this utility model is internally provided with buzzer at casing, and buzzer and sensor parallel, in the normal range ability of sensor, due to buzzer open circuit, buzzer will not work, when sensor reaches capacity position or during no to scale, conducting line segment in connecting rod and the joint in groove contact, now sensor, wire and power supply form the loop of Guan Bi, buzzer works, send alarm and remind operator, this utility model simple in construction, safe and reliable, electronic crane scale can be effectively protected.
