Description
Technical field
The utility model relates to a kind of novel anti-sway damped balance.
Background technology
Often need in Middle School Physics, chemical experiment to use balance, in use procedure, balance both sides pallet one puts counterweight, and one puts article.Counterweight, article quality close to time, balance will swing the long period, could stop.After stopping, user could according to both sides pallet height situation, and find out the article on pallet, counterweight, which is more important.Existing balance duration of oscillation is long, uses inconvenience.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect how overcoming prior art, provides a kind of novel anti-sway damped balance.
For solving the problems of the technologies described above, this novel anti-sway damped balance comprises pedestal, column, crossbeam and two pallets, its central post is fixed on base central, riser is connected with respectively before and after described column top, described riser has through hole, described crossbeam stage casing is clipped between riser, crossbeam mid point is fixed with a jointed shaft, these jointed shaft two ends are stretched in described through hole respectively, crossbeam is hinged between described riser, two pallet symmetries are suspended on crossbeam two ends, it is characterized in that: described crossbeam stage casing has vertical hollow slots, top sheave is provided with in this vertical hollow slots, described jointed shaft passes from top sheave center, top sheave, jointed shaft and crossbeam link into an integrated entity, described column hollow, column bottom has vertical gathering sill and window from top to bottom successively, and be provided with a substrate therebetween, this substrate has vertical through hole, a slide block is provided with in described vertical gathering sill, described slider top is provided with two projections, a lower sheave is provided with between two projections, this lower sheave is by an axle sleeve, an axle is hinged in projection, slider bottom is provided with a screw rod, described substrate is respectively equipped with a volute spring and a nut up and down, described screw rod is passed down through a volute spring and described vertical through hole, by nut, on, the span of lower sheave has annular bracing wire, form pulley-type damping mechanism.
When user needs to eliminate balance swing, turn nut, annular bracing wire tightened, lower sheave is stressed, and the friction force between axle sleeve, axle, lower sheave becomes large, and by the effect of pulley-type damping mechanism, crossbeam stops swinging.Then, nut is turned.Annular bracing wire is fluffed, if crossbeam is motionless, illustrate now, the counterweight on the pallet of balance both sides, article quality are consistent.If the one rise and one drop of crossbeam two ends, then illustrate that the pallet of rising is light, the pallet weighed of decline.
As optimization, column both sides are respectively equipped with a pressure pin, and this pressure pin outer end extends 2 ~ 3 centimeters below described crossbeam.Design like this, can prevent crossbeam two ends from swinging excessive.
It is controlled that this novel anti-sway damped balance has duration of oscillation, advantage easy to use, and applicable primary school, Middle School Students use in an experiment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this novel anti-sway damped balance is described further:
Fig. 1 is the structural representation of this novel anti-sway damped balance;
Fig. 2 is the cross-sectional view (along vertical bisector plane cutting, cutting do not done by screw rod, volute spring, nut, pallet, and slide block only makes biopsy cavity marker devices) of this novel anti-sway damped balance.
