Abstract
The invention relates to a test teaching aid which belongs to the compulsory module 2 of the technology facilitating common application and is about the teaching of 'a relationship between structural stability and structural barycentric position'. During the teaching process, the teaching aid can help students to explore relevant experiments related to the structural stability and the structural barycentric position in a textbook by combining a pen in the hands with the teaching aid in a relatively short period.
Description
Affiliated technical field:
The present invention relates to the special-purpose teaching aid of a kind of current techique course.
Background technology:
At present, because the current techique course is senior middle school's compulsory course that China newly opens, also there is not to be used for a teaching aid about stability test of imparting knowledge to students and using.
Summary of the invention:
This invention provides a kind of and makes things convenient in the required module 2 of current techique, about the test teaching aid of teaching of research " relation of the position of structural stability and center of gravity ".
The technical solution adopted for the present invention to solve the technical problems is: a weight is enclosed within on the penholder, thereby moving heavy object changes the centre of gravity place of pen, thereby be used for authentication center position different stability difference.
The invention has the beneficial effects as follows: this teaching aid can be in teaching process, and the student is enclosed within stability meter easily on the pen that oneself uses and tests, and is simple in structure, easy to operate.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present invention.
1 is the clip of pen clip bar among Fig. 1, the 2nd, and clip fixed bar, the 3rd, the connecting link of clip and weight, the 4th, annular weight
Embodiment:
In Fig. 2, stability meter is enclosed within on the penholder on 5, open clip and move up and down annular weight 4 and fix, of finger or the table angle enterprising line stabilization test of nib profit at oneself to different positions.
Claims (4)
1, a kind of stability meter is characterized in that: this test instrument is the clip 1 by the pen clip bar, clip fixed bar 2, and the connecting link 3 of clip and weight, annular weight 4 common rigidity connect to form.
2, stability meter according to claim 1 is characterized in that: the internal diameter of annular weight 4 is greater than 1 centimetre.
3, stability meter according to claim 1 is characterized in that: be equipped with one on the clip fixed bar 2 and be in the clip 1 of the pen clip bar of concentric shafts position with annular weight 4.
4, stability meter according to claim 1 is characterized in that: the clip 1 of pen clip bar is to be connected with connecting link 3 rigidity of weight by clip with annular weight 4.
