Summary of the invention
Top priority of the present utility model is will provide a kind of can prevent the pallet landing, the counter balance of the architecture advances that helps increasing work efficiency.
Another task of the present utility model be to provide a kind of can be implemented under the aseptic condition weigh, the counter balance of architecture advances applied widely.
For finishing top priority, the technical scheme that provides of the present utility model is: a kind of counter balance of architecture advances, comprise base 5, crossbeam 13, suspension bracket 1, a pair of tray rack 9, a pair of pallet 8, a pair of balance nut 7, pointer 11, scaleplate 12, a pair of baffle plate 4, scale 2, rider 3, the two ends of crossbeam 13 and suspension bracket 1 are hinged, suspension bracket 1 lower end is provided with perpendicular support arm 6, perpendicular support arm 6 can stretch in the hole of base 5 downwards, a pair of tray rack 9 is fixed on the suspension bracket 1 at crossbeam 13 two ends by screw 10 respectively, a pair of balance nut 7 is installed in the two ends of crossbeam 13, pointer 11 is installed in the centre of crossbeam 13, scaleplate 12, a pair of baffle plate 4 is installed on the base 5, scale 2 is installed in the place ahead, middle part of crossbeam 13, rider 3 is slidably mounted on the scale 2, be characterized in: described screw 10 is magnetic screw, described a pair of pallet 8 is separately installed with iron plate 14 in bottom centre, a pair of pallet 8 is fixed on a pair of tray rack 9 with the adhesive of screw 10 by iron plate 14.
For finishing another task, technical scheme provided by the utility model is: the material of described pallet 8 is a metal.
The utility model is because after adopting said structure, one of advantage that has, the iron plate of setting up by the tray bottom and the adhesive of magnetic screw, pallet is inhaled firmly on tray rack, no matter thereby be to move or during weighing, all can effectively prevent the free landing of pallet, help increasing work efficiency; Advantage two, change the material of pallet into metal by original plastics, can carry out autoclave sterilization to metal tray and whole counter balance like this, weigh thereby can be implemented under the aseptic condition, make the scope of application of counter balance wider.
