Abstract
The utility model relates to a simple pendulum. In the simple pendulum, the surface of a base is provided with two holes in which vertical bars can be inserted; short bars are inserted in the holes which the vertical bars are inserted in; the round rods of a support frame are inserted above the short bars. A spherical pendulum is composed of an upper and a lower parts. The upper pendulum is connected with a cotton nylon wire to be hung above a knife edge. Plasticine is placed in the pendulum of the lower part. The utility model can be used for test of the single pendulum, can cause e students to grasp the physical properties of the single pendulum, and can be suitable for use as a teaching aid and a toy.
Description
The utility model relates to a kind of single pendulum, is a kind of teaching aid, cultivates the understanding of student to the physical property of single pendulum, belongs to the technical field of teaching aid.
In child student's teaching naturally, needing the detailed explanation of teacher, at the blackboard corresponding figure that draws, also is time-consuming many, the thing of weak effect, if purchase existing single pendulum utensil, both huge, valency is expensive again, real to the pupil and be not suitable for, need a kind of easy apparatus badly, can make the student understand the performance of single pendulum better, significantly improved its teaching efficiency.
The utility model relates to a kind of single pendulum, and it can remedy above-mentioned deficiency, and single pendulum is simple in structure, is suitable for as teaching aid, and in light weight, pendulum adopts split-type structural, and interior dress plasticine can be aligned pendulum weight.
The purpose of this utility model is achieved in that
A kind of single pendulum, there are 2 holes (2) on the base of its single pendulum (1) surface, montant (3) lower end is inserted in the hole (2), quarter butt (4) is a tubular body, the lower end is connected with a projection (12), can be inserted in the hole (13) of montant (3), support (5) has a round bar, and a transverse arm (15) is extended in the side, and the cross wall upper right side has the pointed edge of a knife (6), the round bar lower end of support (5) is inserted in quarter butt (4) hole, pendulum is made up of two hollow hemisphere (8) (9), puts a plasticine (10) in the bottom pendulum (9), and cotton synthetic fibre line (7) upper end hangs on 2 edges of a knife (6), the hole of top pendulum (8) is passed in the lower end, ties a knot in hammer body.
Base (1) has chimb (18) around the bottom, and the middle part is groove (17), and 2 projections (19) are arranged, projection (19) porose (2).
Fig. 1 single pendulum synoptic diagram;
Fig. 2 base upward view.
Now in conjunction with the accompanying drawings the structure of single pendulum is described in detail:
By Fig. 1, single pendulum has (1) at the bottom of the rectangular base, there are 2 holes (2) on the surface, montant (3) lower end is inserted in the hole (2) of base (1), quarter butt (4) is a tubular body, the lower end is connected with a projection (12), can be inserted in the hole (13) of montant (3), support (5) is straight heart round bar, a transverse arm is extended in the side, the one point of a knife dihedral edge of a knife (6), the just fulcrum of Xuan Guaing arranged at the bottom of transverse arm curved (15), the upper right side of transverse arm, round bar (14) lower end of support (5) directly is inserted in the hole of quarter butt (4), pendulum is two hollow hemispheres (8) (9), and bottom pendulum (9) upper end has flange (11) just in time can get loose with the lower end of top pendulum is chimeric and unlikely, can place a plasticine (10) in the bottom pendulum (9), pass the aperture of top pendulum with cotton synthetic fibre line (7), play a brief summary in hammer body, the other end of line (7) hangs on above the edge of a knife (6) of transverse arm (15), forms a skeleton symbol single pendulum thus.
During online (7) curtailment, can directly support (5) be inserted into above the montant (3) without quarter butt, also can use quarter butt (4) to be inserted in another hole of base (1), the aperture difference in last two holes of base (1) just in time directly matches with bar.
By Fig. 2, around base (1) bottom chimb (18), middle part being arranged is a groove (17), and bottom (1) has 2 projections (19), projection (19) porose (2).
During use, can adjust the length of cotton synthetic fibre line (7), adjust the quantity of plasticine, putting position is observed the Changing Pattern of observing the single pendulum swing speed in the regular hour (60 seconds or 30 seconds), further understands the length of pendulum and the relation of swing speed.Make the student be easy to grasp the characteristic of single pendulum.
Compared with prior art, simple pendulum device has following advantages:
1, simple in structure, the suitable student use of imparting knowledge to students can significantly improve teaching efficiency;
2, montant is divided into two, can be used;
3, pendulum adopts split-type structural, position and the weight that can align plasticine;
4, be convenient to manipulate.
Claims (2)
1, a kind of single pendulum, there are 2 holes (2) on base (1) surface that it is characterized in that single pendulum, montant (3) lower end is inserted in the hole (2), quarter butt (4) is a tubular body, the lower end is connected with a projection (12), can be inserted in the hole (13) of montant (3), support (5) has a round bar, and a transverse arm (15) is extended in the side, and the cross wall upper right side has the pointed edge of a knife (6), the round bar () lower end of support (5) is inserted in quarter butt (4) hole, pendulum is made up of two hollow hemisphere (8) (9), puts a plasticine (10) in the bottom pendulum (9), and cotton synthetic fibre line (7) upper end hangs on the edge of a knife (6), the hole of top pendulum (8) is passed in the lower end, ties a knot in hammer body.
2, single pendulum according to claim 1 is characterized in that around base (1) bottom chimb (18) being arranged, and the middle part is groove (17), and 2 projections (19) are arranged, projection (19) porose (2).
