Abstract

A novel buoyancy generation experiment instrument relates to an experimental device. The novel buoyancy generation experiment instrument comprises a cylindrical container with an opening at the upper end, the container is internally provided with a floating ball, the floating ball is fixedly connected with one end of an elastic body, the other end of the elastic body is fixed at the bottom of the container, and the outer wall of the container is provided with graduation lines. The novel buoyancy generation experiment instrument has the beneficial effects of simple structure, easy manufacture, easy operation, obvious and intuitive experimental phenomenon, easily available raw material and low cost. Physical principles are demonstrated in a clear and easy-to-understand way. The novel buoyancy generation experiment instrument can be used as a teaching instrument and can be used by students as an instrument for extracurricular small experiments.

Description

A kind of novel handle bar sleeve for motor vehicles

Technical field

The utility model relates to a kind of experimental provision, is specifically related to a kind of novel handle bar sleeve for motor vehicles.

Background technology

At present, for most experimental provision complex structure of physics teaching, the scope of application is wideless.And on market almost not to the basic Experiment of Principle of Physics Learning and the experimental provision of making, causing rigidly connecting tactile physical students in middle and primary schools can't be clear understandable to basic physics knowledge, add some theoretical property concepts physically, if do not explained orally analysis, be difficult to allow those students of begining to learn understand, thereby make most students lose learning interest.

The utility model content

Technical problem to be solved in the utility model be to provide a kind of making simple in structure, easy, easy to operate, experimental phenomena obviously intuitively Novel buoyant produce experiment instrument.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of novel handle bar sleeve for motor vehicles, it is characterized in that: comprise the cylindrical container of a upper end open, be provided with a ball float in container, ball float is fixedly connected with an elastomeric end, the described elastomeric other end is fixed on the bottom of container, on the outer wall of described container, is provided with scale mark.

During experiment, in container, add water, ball float can float on the surface, and the water surface continues to raise, and before elastic body is not straightened, ball float is submerged in the following part of the water surface and remains unchanged, and this can verify that ball float swims on the water surface, the relation of buoyancy and gravity; Continue to add water, it is more and more longer that elastic body is stretched, and the part that ball float is submerged in below the water surface simultaneously is also more and more, until the water surface floods ball float fully, then continues to add water, and elastomeric length can not change.

The scale arranged on container outer wall, be convenient to observe elastomeric deformation quantity, also can calculate the variation of elastic body elastic force according to elastomeric elasticity coefficient, also can draw ball float buoyancy and be submerged in the relation of the water surface with the lower sphere size.

Described ball float and elastic body junction are provided with pointer, are convenient to reading.

Described elastic body is spring or rubber bar.

The below of described container side wall is provided with draining valve.

The beneficial effects of the utility model are: the utility model making simple in structure, easy, easy to operate, experimental phenomena is obviously directly perceived, makes that raw material is easy to get, cost is low.What physical principle was demonstrated is clear understandable, can be used as instruments used for education and uses, and also can be used as the outer little experimental apparatus of students in class.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, a kind of novel handle bar sleeve for motor vehicles, the cylindrical container 1 that comprises a upper end open, be provided with a ball float 2 in container 1, ball float 2 is fixedly connected with an end of elastic body 3, and the other end of elastic body 3 is fixed on the bottom of container 1, is provided with scale mark 4 on the outer wall of container 1, ball float 2 is provided with pointer 5 with elastic body 3 junctions, is convenient to reading.

Above demonstration 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 in above-described embodiment and instructions, describes 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.
