Abstract
The utility model relates to an improved dynamometer for teaching which comprises a shell which is internally provided with a spring. One end of the shell is provided with a zero-adjusting device which comprises a spring fixer. One end of the spring which extends out of the shell is connected with a zero-adjusting handle through the spring fixer, and the other end of the spring is connected with a graduated scale which can extend out of the shell. A numerical value of the graduated scale extending out of the shell is a measured value. One end of the shell with the spring is externally provided with a hook. The shell is a transparent shell. Through the arrangement of the transparent shell, students can clearly see an internal structure of the dynamometer, thus the students have strong perceptual knowledge of interaction of forces easily, and a purpose of classroom teaching is achieved.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to specifically a kind of dynamometer.
Background technology
In physics teaching, the size of test force is used dynamometer usually at present, but the dynamometer of use is also opaque now, is not easy to the inner structure of observation of students dynamometer.
The utility model content
Problem to be solved in the utility model is for above problem, provides a kind of intuitive strong, interactional improved teaching dynamometer that can expressive force.
for addressing the above problem, the technical scheme that the utility model adopts is: improved teaching dynamometer, comprise housing, be provided with spring in described housing, one end of described housing is provided with balancing controls, described balancing controls comprise the spring fixator, the end that described spring stretches out described housing is connected with the zeroing handle by described spring fixator, the other end of described spring is connected with rule, described rule can stretch out described housing, described rule stretches out the numerical value of described housing for measuring numerical value, described housing has the outside of spring one end to be provided with hook, described housing is transparent shell.
the utility model is taked above technical scheme, have the following advantages: improved teaching dynamometer, comprise housing, be provided with spring in described housing, one end of described housing is provided with balancing controls, described balancing controls comprise the spring fixator, the end that described spring stretches out described housing is connected with the zeroing handle by described spring fixator, the other end of described spring is connected with rule, described rule can stretch out described housing, described rule stretches out the numerical value of described housing for measuring numerical value, described housing has the outside of spring one end to be provided with hook, described housing is transparent shell, the arranging of transparent shell can allow the clearer inner structure of seeing dynamometer of student, thereby easily the interaction of power produced stronger perceptual knowledge, reaches the purpose of classroom instruction.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
In figure: the 1-housing; The 2-spring; The 3-balancing controls; 31-spring fixator; The 32-handle that returns to zero; The 4-rule; The 5-hook.
Embodiment
Embodiment: improved teaching dynamometer, comprise housing 1, be provided with spring 2 in described housing 1, one end of described housing 1 is provided with balancing controls 3, described balancing controls 3 comprise spring fixator 31, the end that described spring 2 stretches out described housing 1 is connected with zeroing handle 32 by described spring fixator 31, the other end of described spring 2 is connected with rule 4, described rule 4 can stretch out described housing 1, described rule 4 stretches out the numerical value of described housing 1 for measuring numerical value, described housing 1 has the outside of spring one end to be provided with hook 5, and described housing 1 is transparent shell; Described spring fixator 31 is threaded with described spring 2, when zeroing is used, rotating described spring fixator 31 exposes outside described housing 1 zero graduation of rule 4, zeroing handle 32 stretches, make the coincident of zero graduation and the transparent shell of rule 4, rotate described spring fixator 31 and get final product to housing 1, the arranging of transparent shell can allow the clearer inner structure of seeing dynamometer of student, thereby easily the interaction of power produced stronger perceptual knowledge, reach the purpose of classroom instruction.
