Abstract
A kind of device accurately adjusting waling stripe for bohr resonance instrument is related to physics facility field, more particularly to the Level tune of the connecting rod of bohr resonance instrument research Experiment of forced vibration.To overcome, connecting rod Level tune is inaccurate in the experiment that the instrument that resonated using bohr studies forced vibration, devises a device that can accurately adjust connecting rod level, the technical scheme is that：A T-shaped accessory is made, in the center position of connecting rod, is welded together the lower end of T-shaped accessory is vertical with connecting rod, the plane where square plate is parallel with the plane where connecting rod；The upper end of T-shaped accessory is a square disk, and a level meter is fixed at the center of square plate.It, can be accurately by lever regulated for horizontality by level meter when experiment.
Description
Technical field
The present invention relates to physics facility field, more particularly to bohr resonance instrument studies the connecting rod of Experiment of forced vibration
Level tune.
Background technology
In Experiment of College Physics room, it is frequently utilized that bohr resonance instrument research forced vibration.Experimental provision is as shown in Figure 1.It is distant
The lower end of bar is hollow, and screw and is fixed also cross the screw thread hole of distant bar lower end and connecting rod one end using nut.The one of connecting rod
End can be moved up and down using the hollow position of screw, nut in distant bar lower end, and the other end of connecting rod is ined succession eccentric wheel.Change connecting rod
Position at the distant hollow position in bar lower end, so that it may to change the 90 ° of grooves in rocking bar top and eccentric wheel in two photoelectric doors
Position.The 90 ° of grooves in rocking bar top and eccentric wheel are transferred to the center position of two photoelectric doors by experiment before starting, to ensure
The accuracy of measurement period.Because connecting rod is vertical with the extended line of 90 ° of grooves of eccentric wheel, while two photoelectric doors are also at level
State, as long as so by it is lever regulated be horizontality, 90 ° of grooves of eccentric wheel and rocking bar top will be in two photoelectric doors
Middle position.Therefore it is required that instrument, in static state, connecting rod necessarily is in horizontality, still, the level of connecting rod is adjusted at present,
Naked eyes are only leaned on, with feeling.The quantitative examination criteria of neither one can bring prodigious error to experiment in this way.
Invention content
The present invention be overcome using bohr resonance instrument study forced vibration experiment in connecting rod Level tune it is inaccurate, if
A device that can accurately adjust connecting rod level has been counted, can be very good to solve the problems, such as this.
The present invention solve its technical problem the technical solution adopted is that：A T-shaped accessory is made, at the center of connecting rod
At position, weld together the lower end of T-shaped accessory is vertical with connecting rod, where the plane and connecting rod where square plate
Plane is parallel；The upper end of T-shaped accessory is a square disk, and a level meter is fixed at the center of square plate.When experiment, rely on
Level meter can be accurately by lever regulated for horizontality.
The beneficial effects of the invention are as follows:Instrument change is fewer, and improvement cost is low, and can reduce experimental error, improves real
Test precision.
Description of the drawings
Fig. 1 is the bohr resonance instrument device of the prior art, and Fig. 2 is the schematic diagram that the present invention is improved former instrument.
Specific implementation mode
T-shaped accessory is made by ferrous metal, the T-shaped high 3cm of accessory, and the upper end of T-shaped accessory is a pros
The length of side of shape disk, square plate is 2cm, and a level meter is fixed at the center of square plate, will be T-shaped in the center position of connecting rod
The lower end of accessory is vertical with connecting rod to be welded together.
Claims (2)
1. a kind of device accurately adjusting waling stripe for bohr resonance instrument, is made of, feature T-shaped accessory and level meter
It is：The lower end of T-shaped accessory is vertical with the center position of connecting rod to link together, and the upper end of T-shaped accessory is one
Square disk fixes a level meter at the center of square disk.
2. a kind of device accurately adjusting waling stripe for bohr resonance instrument according to claim 1, wherein described
The length of side of the T-shaped high 3cm of accessory, square disk are 2cm.
