Description
Technical field
The present invention relates to fields of measurement, more particularly, it relates to a kind of electronic balance.
Background technology
At present, in the electronic balance that production firm produces, usual employing conventional cantilever beam sensor adds lower support structure, its stability, repeatability etc. performance of weighing is all poor, causes weighing precision general lower, and also needs again to correct the accuracy that guarantee weighs along with environmental change, use very inconvenience, in addition, if be not equipped with accurate counterweight, cannot correct balance, cause using.And high-end electronic balance generally all adopts magnetic levitation sensor construction, performance of weighing is relatively better, but its use cost is relatively high.
On market, the utility model patent that application number is " 200680007291.0 " discloses a kind of shell of electronic balance, it has upper cover, on cover and be provided with detection pallet, the surrounding of described detection pallet is provided with cage, cage offers door, but in actual use procedure, general door can cause air to enter in cage from the gap of door and cage by hinged set-up mode, door and cage are generally made up of glass or acrylic board simultaneously, former and later two faces of the door-plate that glass or acrylic board are made form visible surface, operator can observe the situation in electronic balance in visible surface, general set-up mode is easy to glass or acrylic board are damaged, simultaneously, if balance is used for detecting the density of object under test or the impact of quality when temperature variation, temperature variation is easy to make door-plate produces water smoke, affect the reading that people observe the thermometer be arranged in cage, need to clear up the water smoke on door-plate before upper once experiment, increase unnecessary working time, affect experimental implementation.
The application number applied for before our company is that the Chinese patent of CN2015202166410 discloses a kind of electronic balance with interior school weight structure, in actual use, Electric Machine Control camshaft carries out spin locking thus the position of fixing counterweight, but there is the problem of cam axle keyed end, finally cause the position of counterweight to lock, affect testing result.
Simultaneously, when balance uses, counterweight is not in the lock state, if now balance power-off, counterweight is in measuring position, the counterweight of measuring position can move up and down, and can come off from counterweight frame, now need dismounting balance to keep in repair, if counterweight hits on sensor stand, will cause the precision generation error of electronic balance, and very difficult adjustment is returned.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide the electronic balance that a kind of interior school counterweight locking effect is good.
For achieving the above object, the invention provides following technical scheme: a kind of electronic balance, comprise balance body, described balance body comprises base, sensor and Nei Jiao counterweight mechanism is provided with in described base, described sensor is fixedly connected with interior school ink recorder structure, described interior school ink recorder structure comprises fixed support, movable bracket, counterweight, rotation axis and camshaft, described movable bracket is engaged in vertically movement on fixed support by rotation axis and camshaft, described counterweight is arranged between movable bracket and fixed support, described fixed support is provided with the limiting section preventing camshaft from turning over keyed end.
