Description
Technical field
The utility model is related to a kind of simple type buoyancy meter.
Background technology
It is general to indicate volume markings using one when measuring the buoyancy of object in current physics teaching in secondary school and experiment
Measuring cup, its method is that then the volume V1 of reading water inserts determinand in measuring cup first toward appropriate water is poured into measuring cup,
The volume V2 for inserting water after determinand is read, the V2 differences for subtracting V1 are converted into the measurement unit ox of power by Archimedes' principle
, it is exactly the buoyancy of determinand.Still an alternative is that the weight T of determinand is first weighed up with spring scale, then again determinand
Insert in water and be re-weighed, obtain weight T1 of the determinand in water, the difference that T subtracts T1 is passed through conversion, can also obtained to be measured
The buoyancy of thing, but both apparatus being related to are more, it is more inconvenient to operate.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of simple type buoyancy meter, the structure of the buoyancy meter
It is easily operated while simple.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of simple type buoyancy meter,
Its structure includes measuring cylinder, spring and telescopic arm, and the measuring cylinder is hollow cylindrical structure, and the spring is built in measurement

The end of telescopic arm is connected with the pin of changeable type three fork, and its head is stretched into measuring cylinder, and is fed through spring, is further connected to
In graduated scale, graduation mark is additionally provided with the outer tube wall of the measuring cylinder.
Further, the afterbody of the telescopic arm offers a through hole, the pin of changeable type three fork plug with through hole, and
It is fixed by bolt phase both.
Further, the leg of the pin of changeable type three fork is in convex structure.
Further, it is transparent visual windows that the measuring cylinder, which is indicated at graduation mark,.
Further, a lead for being easy to be oriented to graduated scale is additionally provided with the measuring cylinder.
Further, a hanger for being used to hang it is additionally provided with the top of the measuring cylinder.By above-mentioned to this
The description of utility model structure understands that compared to the prior art, the utility model has the following advantages that：
A kind of simple type buoyancy meter that the utility model is provided, by using by measuring cylinder, spring, telescopic arm and can
The pin of modification three fork etc. is combined the buoyancy meter of composition so that the buoyancy meter it is simple in construction, be easy to operation, practicality
By force.
