Description
Technical field
The utility model is related to teaching aid field, and in particular to a kind of Physical Experiment dynamometer.
Background technology
Weight beam is a kind of instrument of dynamometry size, and its principle is：First, any measurement is all by some physics
Amount and standard（That is unit）The process compared, the measurement of power is compared the action effect of power with the action effect of known force
Process；If the action effect of a power is identical with 1 Niu Li action effect, the size of this power is exactly 1 N；Secondly, spring
Elongation be directly proportional to the size of institute stress, it is determined that after 1 Niu Li action effect, in this way it is easy to determine more energetically and less force
Action effect.
Weight beam is the experimental provision that must be used during Physics Learning, existing weight beam structure design
Single, the less stable of spring reuses number of times limited；Therefore the size of power can be measured with weight beam.It is actual
During measurement, due to weight beam it is descending during can by reasons such as certain resistance or nosing forces, spring can deviate operation rail
Mark, causes measurement error to become big.
The content of the invention
To solve problem of the prior art, the utility model provides a kind of accurate Physical Experiment dynamometer of measurement.
In order to achieve the above object, the utility model uses following technical scheme：A kind of Physical Experiment dynamometer, including
Corresponding graduation mark is set in housing, housing, and annulus is fixed on the top of housing, and enclosure interior upper end is connected with spring one end,
The spring other end is connected with indicating arm, and indicating arm lower end is fixedly connected below pull bar, pull bar and is fixedly connected hook, the indicating arm
It is arranged in stopper slot, stopper slot includes setting spacing slideway, enclosure interior in the limiting plate for being arranged at spring both sides, limiting plate
Suspension member is fixedly installed in upper end, and suspension member is detachably connected with spring, and fixation outside direction needle, the housing is fixedly installed on indicating arm and sets
Translucent cover is put, the back side of shell is wholely set in rectangular recess, rectangular recess detachable setting magnetic block, and housing upper is set
Level meter.
The utility model reasonable in design, simple to operate, dynamometry accuracy is high, and stopper slot coordinates indicating arm to cause dynamometry
Spring in meter is stable, does not deviate by running orbit, adds the stability and accuracy of dynamometry, and direction needle can be further
Pin-point reading, rectangular recess and rectangular magnetic Block- matching are set, be easy to housing to be fixed on metallic plate, it is to avoid student is for a long time
Lift dynamometer.

1 upper end is directly fixedly connected.
It is fixedly installed direction needle 6 on indicating arm 7, direction needle 6 can further pin-point reading.
Translucent cover 11 is fixedly installed outside housing 1, translucent cover 11 is by bolt or is fastened on housing 1, plays protection
Effect.
The back side of housing 1 is wholely set in rectangular recess 14, rectangular recess 14 detachable setting magnetic block 15, rectangular recess 14
Setting is matched with rectangular magnetic block 15, it is easy to housing 1 to be fixed on metallic plate, it is to avoid student lifts dynamometer for a long time.
The top of housing 1, which is set in level meter 12, level meter 12, bubble 13, for causing dynamometer horizontal positioned.
The common structure that the structure that the utility model is not pointed out should know for those skilled in the art, the utility model
The conventional connected mode that the connected mode do not pointed out should know for those skilled in the art.
The above, is only preferred embodiment of the present utility model, is not to make other forms to the utility model
Limitation, any those skilled in the art are changed or are modified as possibly also with the technology contents of the disclosure above equivalent
