Abstract
A cushion damping resistance strain-gauge weighing transducer takes the shape of a cuboid; a strain district is arranged at the middle part of the weighing transducer; a plurality of cushion holes are formed at least on one of the left and right sides of the strain district; and damping material can be or not be poured into the cushion holes. The weighing transducer provided by the utility model can quickly absorb and relieve the impact and the vibration which are generated when objects are placed on the weighting platform, and can make the transducer be stable very soon, thereby increasing the weighing speed.
Description
Technical field
The utility model relates to sensor, and particularly the sensor of measurement instrument use specifically, is the resistance strain weighing transducer that a kind of electronic scales uses.
Background technology
At present, the LOAD CELLS of electronic scales adopts the parallel girder structure usually, and the elastic body of sensor is generally rectangular shape, is made by aluminium alloy, alloy steel or high-strength stainless steel.One end of sensor is installed to by screw on the weighing platform of electronic scales, and the other end of sensor is fixed on the leg by screw.
The sensor middle part of parallel girder structure is provided with strain regions, and the structural shape of strain regions has square hole, single hole, diplopore, five holes etc., and strain ga(u)ge is attached on the maximum stress point of strain regions.
Existing sensors has only strain regions, does not have the vibration reduction and cushioning district, and when the weighing article, if article are not to be put into lightly on the weighing platform, the impact of generation may cause the sensor overload to damage.The vibration that this impact produces, if can not be absorbed alleviation very soon, scale reaches the stable long process that needs, the weight of a weighing object just needs the long time.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of buffering damping resistance strain gauge load cell, can fast Absorption alleviate the shock and vibration that produce when article are placed on the weighing platform, prevent the damage of sensor overload, and sensor can be settled out soon, thereby improve measuring speed.
For achieving the above object, the utility model is by the following technical solutions:
A kind of buffering damping resistance strain gauge load cell is rectangular shape, and its middle part is provided with strain regions, it is characterized in that: have several cushion holes Yi Bian the left and right both sides of described strain regions have at least.
The direction of described cushion hole is consistent with the Width of sensor.
Described cushion hole is the through hole through sensor.
Described cushion hole is not through the blind hole of sensor.
Be filled with damping material in the described cushion hole.
Owing to adopt technique scheme, sensor of the present utility model had both had strain regions, has the damping district again, can fast Absorption alleviate the shock and vibration that produce when article are placed on the weighing platform, improve the shock resistance of sensor, improved the speed of weighing, it is more reliable and more stable to work, thereby has guaranteed the serviceable life and the measuring speed of electronic scales.

Embodiment
Number in the figure
1 sensor, 2 strain regions, 3 maximum stress points, 4 maximum stress points
6 the right, 5 left sides, 7 legs, 8 cushion holes
9 screws, 10 screws, 11 cushion holes
12 damping materials, 13 weighing platforms
Embodiment one
Please refer to Fig. 1, Fig. 2, the utility model is a kind of buffering damping resistance strain gauge load cell, is rectangular shape, and the middle part of this sensor 1 is provided with strain regions 2, the middle part on sensor 1 upper and lower surface, the position corresponding with strain regions 2 is the maximum stress point 3,4 of sensor.
Strain ga(u)ge sticks on the maximum stress point 3,4, and the right 6 of strain regions 2 has cushion hole 8.The direction of cushion hole 8 is consistent with the Width of sensor 1, and cushion hole 8 can be the long trough through hole through sensor 1, also can be not through the long trough blind hole of sensor 1.
In the present embodiment, the quantity of cushion hole 8 is three, when implementing, the quantity of cushion hole 8 can change accordingly according to sensor 1 thickness difference, when sensor 1 is thin, the quantity of cushion hole 8 can be one or two, and when sensor 1 was thicker, the quantity of cushion hole 8 can be three or more.Cushion hole 8 makes the right 6 of strain regions 2 become the hollow out shape, can fast Absorption alleviates the shock and vibration that produce when article are placed on the weighing platform, prevents that the sensor overload from damaging, and makes the sensor can very fast settling out, thereby improves measuring speed.
Also be provided with screw 9 longitudinally on the right 6 of strain regions 2, screw 9 is used for being connected with leg 7.
Bottom on the left side 5 of strain regions 2 is provided with screw 10 longitudinally, and screw 10 is used for being connected with the weighing platform underframe.
Embodiment two
Please refer to Fig. 3, Fig. 4, present embodiment and the foregoing description one are basic identical, and difference is: the left side 5 at strain regions 2 also has cushion hole 11, thereby more effectively discharges the local stress that shock and vibration produce, and improves measuring speed.
Embodiment three
Please refer to Fig. 5, Fig. 6, present embodiment and the foregoing description one are basic identical, and difference is: be filled with damping material 12 in cushion hole 8, damping material 12 has the effect of energy-absorbing, can absorb shock and vibration, damping material 12 can be polyurethane, natural rubber, silicon rubber etc.
Please refer to Fig. 7, during use, bolt corresponding on the screw 10 of 5 bottoms, the left side of sensor 1 and weighing platform 13 underframes is connected, the screw 9 on the right 6 of sensor 1 is connected with double-screw bolt on the leg 7.Owing to have cushion hole 8 on the sensor 1, be filled with damping material 12 in the cushion hole 8, so can fast Absorption alleviate the shock and vibration that produce when article are placed on the weighing platform 13, improve the load characteristic curve of sensor, improve sensitivity, it is more reliable and more stable to work, thereby has improved the serviceable life and the weighing speed of electronic scales.
