Description
Technical field
The utility model relates to physics teaching experiment apparatus field, specifically Hooke's law experiment demonstrator.
Background technology
Existing Hooke law demonstrator mainly demonstrates spring when being elongated, its length of extending is directly proportional to external force, but current demonstration device cannot demonstrate spring, and when being compressed, it is also directly proportional to external force by the length compressed, this makes teacher be difficult to express with experiment in teaching process, student can not get information about and either way meet Hooke's law, brings certain difficulty to teaching.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provides a kind of rational in infrastructure, easy to operate Hooke's law experiment demonstrator.
The utility model solves the technical scheme that its technical matters adopts: this Hooke's law experiment demonstrator comprises spring strut and spring, and the top of spring strut is uncovered, and bottom end closure has bottom, and the center of bottom is provided with through hole; The top of spring is connected with hook two, the bottom of spring is fixedly connected on the bottom in spring strut by fixed screw, the bottom of spring is provided with hook one, and hook one is connected by the top of the connecting rod with spring that are arranged on spring center, and hook one passes the below of the through hole on bottom to bottom; The side of the uncovered top of spring strut is provided with positioning baffle, and opposite side is provided with sliding panel, and the inside surface of sliding panel is provided with chute, and sliding panel is slidably matched by the slide rail of chute and spring strut side.
The outside surface of described sliding panel is provided with scale mark.
The side of described spring is provided with the pointer pointing to sliding panel high scale line.
It is view window between described positioning baffle and sliding panel.
Hooke's law experiment demonstrator of the present utility model compared to the prior art, have reasonable in design, structure simple, be easy to processing, the feature such as easy to use, cheap, spring can be demonstrated in the relation of extending and between compressive state and external force, effectively raise efficiency of teaching and the quality of instruction of teacher, make student comprehensively understand Hooke's law.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
Hooke's law experiment demonstrator of the present utility model, its structure comprises spring strut 1 and spring 10, and the top of spring strut 1 is uncovered, and bottom end closure has bottom 2, and the center of bottom 2 is provided with through hole 4; The top of spring 10 is connected with hook 2 11, the bottom of spring 10 is fixedly connected on the bottom in spring strut 1 by fixed screw 14, the bottom of spring 10 is provided with hook 1, link up with 1 to be connected with the top of spring 10 by the connecting rod 15 being arranged on spring 10 center, hook 1 is through the below of through hole 4 to the bottom 2 on bottom 2; The side of the uncovered top of spring strut 1 is provided with positioning baffle 12, opposite side is provided with sliding panel 8, it is view window 13 between positioning baffle 12 and sliding panel 8, the inside surface of sliding panel 8 is provided with chute 6, sliding panel 8 is slidably matched by the slide rail 5 of chute 6 with spring strut 1 side, the outside surface of sliding panel 8 is provided with scale mark 7, and the side of spring 10 is provided with the pointer 9 pointing to sliding panel 8 high scale line 7.
Using method:
When needs do experimental demonstration Hooke's law, vertically pick up spring strut 1 with hand, make hook 2 11 downwardly ground, adjust the position of sliding panel 8 up and down, make pointer 9 point to 0 scale mark 7, then on hook 2 11, hang up hook code, now spring 10 is stretched; Then turnover spring cylinder 1, makes hook 1 downwardly ground, and adjust the position of sliding panel 8 up and down, make pointer 9 point to 0 scale mark 7, then on hook 1, hang up hook code, now spring 10 is compressed.By above-mentioned experiment, can clearly show no matter spring 10 is stretched or is compressed in elastic limit to student, the length of stretching and the length of compression are all directly proportional to external force.
By embodiment above, described those skilled in the art can be easy to realize the utility model.But should be appreciated that the utility model is not limited to above-mentioned several embodiments.On the basis of disclosed embodiment, described those skilled in the art can the different technical characteristic of combination in any, thus realizes different technical schemes.
