Abstract
The utility model discloses a spring elasticity demonstration device, comprising a pedestal, a vertical column fixed on the pedestal and an elastic base, wherein the elastic base is provided with a circular hole, the vertical column is inserted in the circular hole, a spring is sleeved on the vertical column at the lower part of the elastic base, the top part of the spring is fixedly connected with the elastic base, the bottom part of the spring is fixed on the pedestal, the left side and the right side of the elastic base are respectively provided with a ball hole, elastic balls are arranged in the ball holes, an uprightly arranged ruler is fixed on the pedestal, and the rule is provided with length scales. The utility model has the beneficial effects that: (1) the structure is simple; (2) the relationship between the elasticity and deformation of the spring can be demonstrated directly; (3) by reading the length scales on the uprightly arranged rule which is fixed on the pedestal, the amount of deformation and the bounce height of the elastic balls can be observed quantitatively, and the relationship between the amount of deformation and the elasticity and of the spring can be further expounded.
Description
Technical field
The utility model relates to a kind of physics teaching and uses experimental apparatus, particularly a kind of spring force demonstration device.
Background technology
At present, in physics teaching practice, during the concerning of the elastic force of explaining spring as the teacher and its distortion, because less than demonstration equipment intuitively, thereby can only do theoretic abstract explanation, and cause the student to be difficult for understanding this knowledge point thus, the effect of giving lessons is relatively poor.
Summary of the invention
The problem that the utility model will solve is: a kind of spring force demonstration device is provided, and this demonstration device is not only simple in structure, and can show the elastic force of spring and the relation of its distortion intuitively.
In order to solve the problems of the technologies described above, the spring force demonstration device of the utility model comprises base, is fixed on column and elastic force seat on the base; Said elastic force seat is provided with circular hole, and said column is inserted in the circular hole, is socketed with spring on the column of said elastic force seat below; The top of said spring is fixedly connected with the elastic force seat; The bottom is fixed on the base, and the left and right sides of said elastic force seat is equipped with a ball hole, and said ball is placed with the elastic force ball in the hole.
For the ease of the height that observation elastic force ball is upspring, the spring force demonstration device of the utility model also is fixed with a ruler of vertically placing on the said base, and said ruler is provided with the length scale.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) press the down spring seat,, rapidly hand is taken away then length of spring compressed; This moment, the elastic force ball was upspring under the effect of spring force, and it is big more that spring is compressed distortion; Then the elastic force ball height of upspringing is high more, thereby demonstrates out the elastic force of spring and the relation of its distortion intuitively; (3) also be fixed with a ruler of vertically placing on the base; Ruler is provided with the length scale; Through the length scale on the ruler, the height that deflection that observes length of spring compressed that can be quantitative and elastic force ball are upspring is further illustrated the deflection of spring and the relation of elastic force size.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, elastic force seat, 2, the elastic force ball, 3, the ball hole, 4, column, 5, circular hole, 6, the length scale, 7, ruler, 8, base, 9, spring.
Embodiment
As shown in Figure 1, the spring force demonstration device of the utility model comprises base 8, is fixed on column 4 and elastic force seat 1 on the base 8; Said elastic force seat 1 is provided with circular hole 5, and said column 4 is inserted in the circular hole 5, is socketed with spring 9 on the column 4 of said elastic force seat 1 below; The top of said spring 9 is fixedly connected with elastic force seat 1; The bottom is fixed on the base 8, and the left and right sides of said elastic force seat 1 is equipped with a ball hole 3, is placed with elastic force ball 2 in the said ball hole 3; Also be fixed with a ruler 7 of vertically placing on the said base 8, said ruler 7 is provided with length scale 6.
In the time of demonstration, firmly press down elastic force seat 1, with spring 9 compression deformations; Rapidly hand is taken away then, this moment, elastic force ball 2 was upspring under the effect of spring 9 elastic force; The compress variation of height that elastic force ball 2 is upspring and spring 9 can read through the length scale 6 on the ruler 7; Can find that in the process of demonstration it is big more that spring 9 is compressed distortion, then elastic force ball 2 height of upspringing is high more; Thereby demonstrate out the elastic force of spring 9 and the relation of its distortion intuitively, help the understanding of student this knowledge point.
The spring force demonstration device of the utility model; Also be fixed with a ruler 7 of vertically placing on the base 8; Ruler 7 is provided with length scale 6; Through the length scale 6 on the ruler 7, the height that deflection that observes spring 9 compressions that can be quantitative and elastic force ball 2 are upspring, thus further illustrate the deflection of spring 9 and the relation of elastic force size.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
