Abstract
The utility model relates to a lifting sound velocity measurement experiment frame which belongs to the teaching experiment apparatus. The experiment frame comprises a test frame, a test energy converter and a liquid groove. The utility model is technologically characterized in that a lifting mechanism is arranged between the inner walls arranged at both sides of the test frame and the liquid groove; the lifting mechanism has the structure that the inner walls at both sides of the test frame are provided with guide rods, and both sides of the liquid groove are provided with concave-convex guide grooves which are corresponding; each guide rod is provided with a location mechanism. The utility model has the advantages that the liquid groove can move up and down under the condition of keeping the test energy converter still, and the test accuracy is enhanced because of the fixation of the test energy converter; the utility model does not occupy the desktop space; two media can conveniently carry out the switching operation, and moreover, the injury condition does not easily happen.
Description
Technical field:
The utility model relates to teaching and experiment equipment; Be meant the sound velocity determination experimental apparatus especially.
Background technology:
Existing sound velocity determination experiment frame, have 1. air type, 2. liquid tank type and 3. make things convenient for air and two kinds of measuring media of liquid in three kinds on the dismountable type determination experiment frame of handover measurement.The first two plants experiment frame can only carry out the acoustic velocity measutement experiment at single medium; The third promptly can also can carry out experiment in the liquid in air, when promptly needing to measure in the liquid velocity of sound, liquid bath is put in the testing jig, when MEASURING THE VELOCITY OF SOUND IN AIR, must take out liquid bath in testing jig again, is placed on other place.Its shortcoming is 1, testing transducer and liquid bath need to take desk-top space respectively; 2, when testing jig and liquid bath shirked, the moisture content on the testing jig dripped, and stays the water mark on the table; 3, testing transducer is in motion, and liquid bath is motionless, owing to rocking of testing transducer influences the test effect; 4, each testing jig lumps together with liquid bath or when separating, and all must take a lot of work and arduously the two be alignd when parallel, and easily angle, corner, limit be damaged when shirking.
Summary of the invention:
The purpose of this utility model be to overcome above deficiency and provide a kind of need not require great effort to take into take out, can make testing transducer to maintain static, only need the liquid bath lift sound velocity determination experiment frame of small amplitude slip up and down.
The utility model is achieved by the following technical solution: this experiment frame, comprise testing jig, testing transducer, liquid bath, and its major technique feature is to be provided with elevating mechanism between testing jig both sides inwall and the liquid bath;
Described elevating mechanism is that testing jig both sides inwall is established guide rod, and the liquid bath both sides are provided with corresponding cancavo-convex guide groove, and guide rod is provided with detent mechanism;
Described detent mechanism is to connect spring by register pin.
The utlity model has following advantage: 1, testing transducer is motionless, and liquid bath oscilaltion campaign is because the testing precision that fixedly makes of testing transducer improves.2, liquid bath is fixed on the testing jig, just moves up and down in shelf, does not take desk-top space.3, when MEASURING THE VELOCITY OF SOUND IN AIR, liquid bath puts down, and when transducer surfaced, the moisture content on the testing jig splashed in the liquid bath, can not stay the water mark on the table.4, two kinds of medium blocked operations are convenient, and are not easy to produce damage.
Description of drawings:
Structural representation of the present utility model when Fig. 1 goes up for liquid tank;
Fig. 2 is liquid tank decline back structural representation of the present utility model;
Fig. 3, Fig. 4 are the structural representation of liquid tank;
Fig. 5 is the johning knot composition of testing jig inwall guide rod, register pin.
Embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, lift sound velocity determination experiment frame, comprise testing jig 1, testing transducer 2, liquid bath 3, guide rod 4 is set up in test, the liquid bath both sides are provided with between 6, two straight-bars of two parallel straight-bars and form groove, for guide rod along this guide groove that moves up and down 5, guide rod is provided with register pin 7, and register pin connects spring 8.
When measuring the airborne velocity of sound, liquid bath is placed on the testing jig bottom, and when needs were measured in the liquid velocity of sound, when liquid bath moved upward to certain position along guide rod, register pin ejected under spring action automatically, holds liquid bath, and liquid bath is stopped in the air.
Claims (3)
1, a kind of lift sound velocity determination experiment frame comprises test being arranged with transducer, liquid bath on testing jig, the testing jig, it is characterized in that being provided with elevating mechanism between testing jig both sides inwall and the liquid bath.
2, a kind of lift sound velocity determination experiment frame as claimed in claim 1 is characterized in that described elevating mechanism is that testing jig both sides inwall is established guide rod, and the liquid bath both sides are provided with corresponding cancavo-convex guide groove, and guide rod is provided with detent mechanism.
