Abstract
The utility model provides a simple-pendulum scientific experimental device and relates to an experimental device. A pedestal is arranged in the bottom. A fixed rod is arranged on the pedestal. A plastic rod is arranged on a side of the top of the fixed rod vertically. A plastic ball is suspended on the plastic rod through a thread. A slide sleeve is installed on the fixed rod. A plastic sheet is connected to a side of the slide sleeve. The utility model proves that the longer a simple pendulum is, the lower the hunting frequency is. The simple-pendulum scientific experimental device is simple in structure and easy to manufacture and operate. Experimental phenomenon can be shown obviously and directly. Manufacturing raw material is easy to get and low in cost. Physical principles can be demonstrated clearly and understandable. The simple-pendulum scientific experimental device can also be used as a teaching instrument or a small extracurricular experimental instrument for students. The simple-pendulum scientific experimental device provided by the utility model is well-formed, and is elegant in color and nice in appearance, so that the simple-pendulum scientific experimental device has an artistic aesthetic effect and becomes a decoration on a table or in a cabinet. The simple-pendulum scientific experimental device has an enlarged application range and becomes a practical novel product.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to a kind of single pendulum scientific experiment device.
Background technology
At present, be used for most experimental provision complex structure of physics teaching, the scope of application is wideless.And almost the basic principle of physics study is not tested and the experimental provision of making on the market, 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 forfeiture learning interest.Simultaneously, most physical experiment apparatus all can not as ornaments or handicraft puts on display.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of making simple in structure, easy, outward appearance are more art up, the obvious device of single pendulum scientific experiment intuitively of experimental phenomena.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of single pendulum scientific experiment device, it is characterized in that: the bottom is provided with base, base is provided with fixed bar, fixed bar top one side vertically arranges a plastic bar, on the plastic bar by hanging a baton round under the alignment, at fixed bar slip cap is installed, slip cap can move up and down along fixed bar.Slip cap one side connects plastic sheet.
Described plastic sheet is provided with aperture, and line passes aperture and connects baton round, and plastic sheet and slip cap are in conjunction with the length that can control the baton round pendulum length.
Described plastic bar and plastic sheet are horizontally disposed with and are located at fixed bar one side.
Allow baton round swing, mobile slip cap gradually up or down, slip cap moves up, and what the frequency of baton round swing will be gradually is slack-off, and slip cap moves down, and the frequency of baton round swing will accelerate gradually.
The beneficial effects of the utility model are: the utility model has proved that the pendulum length of single pendulum is more long, and the frequency of swing is more low.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.Clear understandable with physical principle demonstration can be used as instruments used for education and uses, and also can be used as the extracurricular little experimental apparatus of student.Lines of the present utility model are beautiful clean, and color grace, outward appearance are dazzled extremely, and experimental apparatus is art up, become the ornament on the table, in the cupboard, and the purposes of experimental apparatus obtains expanding, and becomes practical novel products.
Description of drawings
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.
A kind of single pendulum scientific experiment device as shown in Figure 1, the bottom is provided with base 1, base 1 is provided with fixed bar 2, fixed bar 2 tops one side vertically arranges a plastic bar 3, hang a baton round 5 downwards by line 4 on the plastic bar 3, at fixed bar 2 slip cap 6 is installed, slip cap 6 can move up and down along fixed bar 2.Slip cap 6 one sides connect plastic sheet 7.Plastic sheet 7 is provided with aperture, and line 4 passes aperture and connects baton round 5, and plastic sheet 7 and slip cap 6 are in conjunction with the length that can control baton round 5 pendulum lengths.Plastic bar 3 and plastic sheet 7 are horizontally disposed with and are located at fixed bar 2 one sides.
Allow baton round 5 swing, mobile slip cap 6 gradually up or down, slip cap 6 moves up, and what the frequency of baton round 5 swings will be gradually is slack-off, and slip cap 6 moves down, and the frequency of baton round 5 swings will accelerate gradually.The pendulum length that has proved single pendulum is more long, and the frequency of swing is more low.
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.
