The structure of the Hooke law demonstrator comprises an outer sleeve body, an inner sleeve body and springs; the outer sleeve body and the inner sleeve body respectively consist of two arc strips; the bottom parts of the two arc strips of the outer sleeve body are fixed on a round outer sleeve bottom plate; the outer sleeve bottom plate is provided with two arc holes; the bottom parts of the two arc strips of the inner sleeve body are fixed on a round inner sleeve bottom plate; the two arc strips of the inner sleeve body respectively correspondingly pass through the two arc holes on the outer sleeve bottom plate; the upper parts of the two arc strips of the inner sleeve body are provided with pin holes for pins to be inserted in; springs are sleeved outside the two arc strips of the inner sleeve body; the top ends of the springs are provided with pointers; and the bottom ends of the springs are contacted with the outer sleeve bottom plate. Compared with the prior art, the Hooke law demonstrator of the utility model has the characteristics of reasonable design, simple structure, easy processing, convenient use and the like, effectively improves teaching efficiency and teaching quality of teachers and makes students comprehensively understand the Hooke law.
Description
Technical field
The utility model relates to the physics teaching apparatus field, specifically the Hooke's law demonstration device.
Background technology
Existing Hooke's law demonstration device mainly is that the demonstration spring is when being elongated, the length of its elongation is directly proportional with external force, its compressed length when being compressed also is directly proportional with external force but present demonstration device can't be demonstrated spring, this makes that the teacher is difficult to express with experiment in teaching process, the student can not get information about and either way meet Hooke's law, brings certain degree of difficulty to teaching.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of Hooke's law demonstration device simple in structure, easy to use is provided.
The technical scheme that its technical matters that solves the utility model adopts is: this demonstration device comprises outer sleeve body, interior body and spring, outer sleeve body and interior body constitute by two arcs are rectangular respectively, two rectangular bottoms of arc of outer sleeve body are fixed on the circular overcoat base plate, and the overcoat base plate is provided with two arcuate sockets; Two rectangular bottoms of arc of interior body are fixed on the circular interior cover base plate, rectangular corresponding respectively two arcuate sockets that pass on the overcoat base plate of two arcs of interior body, two rectangular tops of arc of interior body have the pin hole that inserts bayonet lock, the rectangular outer spring that is with of two arcs of interior body, the top of spring is provided with pointer, and the bottom of spring contacts with the overcoat base plate.
Two rectangular tops of arc of described outer sleeve body are provided with lanyard.
The bottom of cover base plate is provided with the link that hangs counterweight in described.
The rectangular outside surface of the arc of described outer sleeve body is provided with scale mark.
Hooke's law demonstration device of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as easy to use, effectively raise teacher's efficiency of teaching and quality of instruction, make the student comprehensively understand Hooke's law.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of Hooke's law demonstration device.
Among the figure: 1, lanyard, 2, outer sleeve body, 3, interior body, 4, bayonet lock, 5, pointer, 6, scale mark, 7, pin hole, 8, spring, 9, the overcoat base plate, 10, arcuate socket, 11, link, 12, interior cover base plate, 13, counterweight.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Hooke's law demonstration device of the present utility model, its structure comprises outer sleeve body 2, interior body 3 and spring 8, outer sleeve body 2 and interior body 3 constitute by two arcs are rectangular respectively, two rectangular tops of arc of outer sleeve body 2 are provided with lanyard 1, the rectangular outside surface of the arc of outer sleeve body 2 is provided with scale mark 6, two rectangular bottoms of arc of outer sleeve body 2 are fixed on the circular overcoat base plate 9, and overcoat base plate 9 is provided with two arcuate sockets 10; Two rectangular bottoms of arc of interior body 3 are fixed on the circular interior cover base plate 12, the bottom of interior cover base plate 12 is provided with the link 11 that hangs counterweight 13, rectangular corresponding respectively two arcuate sockets 10 that pass on the overcoat base plate 9 of two arcs of interior body 3, two rectangular tops of arc of interior body 3 have the pin hole 7 that inserts bayonet lock 4, the rectangular outer spring 8 that is with of two arcs of interior body 3, the top of spring 8 is provided with pointer 5, and the bottom of spring 8 contacts with overcoat base plate 9.
During teaching, bayonet lock 4 is inserted in the pin hole 7, thereby the top of fixing spring 8 hangs up counterweight 13 then on link 11, spring 8 is compressed, the length of pointer 5 indication compressions.Thereby show that spring 8 compressed length also are directly proportional with external force.
Its processing and fabricating of Hooke's law demonstration device of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
