Abstract
The utility model discloses a physics teaching tool, which comprises a base (1). A telescopic strut (2) is arranged on the base (1). The telescopic strut (2) is connected with a telescopic cross bar (5) through adjusting bolts. The two sides of the telescopic cross bar (5) are provided with a clump weight (4) respectively. The telescopic cross bar (5) can be folded up and rotated. According to the technical scheme of the utility model, the physics teaching tool is foldable, rotatable, scalable, small in volume and convenient to carry about. Therefore, the physics teaching tool can be applied to not only lever balance experiments but also gravity testing experiments.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of physics teaching instrument.
Background technology
Many laws of physics have only by experiment introduce, just can make the student deep more, derive and checking, so just need suitable experimental tool
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of Physical Experiment instrument, and collapsible, rotatable, scalable, volume is little, and is easy to carry.
For achieving the above object, the utility model proposes a kind of physics teaching instrument, comprise base, described base is provided with telescopic support struts, described telescopic support struts is connected by regulating bolt with scalable cross bar, described scalable cross bar both sides are equipped with balancing weight, and described scalable cross bar is collapsible, rotatable.
The utility model is simple in structure, and is collapsible, rotatable, scalable, and volume is little, easy to carry, both can apply to the lever balance experiment, can apply to the gravity test experiments again.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the rotation of the utility model cross bar, the structural representation after folding;
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: one one kinds of physics teaching instruments, comprise base 1, described base 1 is provided with telescopic support struts 2, described telescopic support struts 2 is connected by regulating bolt with scalable cross bar 5, described scalable cross bar 5 both sides are equipped with balancing weight 4, and described scalable cross bar 5 is collapsible, rotatable.
The utility model is simple in structure, and is collapsible, rotatable, scalable, and volume is little, easy to carry, both can apply to the lever balance experiment, can apply to the gravity test experiments again.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
