Abstract
The utility model discloses a dynamometer, belonging to the technical field of measuring and testing device, and in particular relates to the improvement of a dynamometer structure. The utility modelprovides a dynamometer with the advantages of high precision and convenient use. The dynamometer can be applied to measure the strength and demonstrate experiment in classroom teaching of physical class in middle school. The dynamometer comprises a pedestal, wherein the pedestal is provided with an upright plate with a graduated disc and a strut; a shaft is arranged between the upright plate andthe strut, and is fixed with a rotating disc with a coiling groove and an indicating needle corresponding to the graduated disc; the coiling groove is connected with one end of a cotton rope; and a shaft is connected with the upright plate by a clockwork spring.
Description
Technical field:
The utility model belongs to measurement, testing apparatus technical field, more particularly, relates to a kind of improvement of dynamometer structure.
Background technology:
At present, people in daily life and the teacher in middle school physics classroom teaching, during test force big or small, the instrument that adopts is a weight beam usually.This weight beam is to utilize spring stress that deformation can take place, within the specific limits the principle that is directly proportional with deformation quantity of the size in; So, can measure the size of power by the deformation quantity of spring.But the shortcoming of this weight beam is a low precision, promptly can not be by the faint variation of spring stress, and the pointer on spring shows; Therefore, brought inconvenience not only for the work of people's test force size, be unfavorable for that also the teacher carries out the teaching demonstration work in classroom.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of precision height, dynamometer easy to use are provided; This dynamometer can be widely used in the classroom instruction lecture experiment of the size of ergometry and middle school physics.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises base, its structural feature is that base is provided with riser and the pillar that top has index dial, between riser and pillar, be provided with axle, on axle, be fixed with rotating disk and, link to each other with an end of cotton rope in the described coiling groove, spool link to each other with riser by clockwork spring corresponding to the pointer of index dial with coiling groove.
The beneficial effects of the utility model:
Because dynamometer base of the present utility model is provided with riser and the pillar that top has index dial, between riser and pillar, be provided with axle, on axle, be fixed with rotating disk and corresponding to the pointer of index dial with coiling groove, link to each other with an end of cotton rope in the described coiling groove, axle links to each other with riser by clockwork spring; By cotton rope being applied the effect of power, thereby make clockwork spring faint elastic deformation take place, be presented on the index dial through pointer; So, measuring accuracy height not only, and easy to use.Be applied in the life, provide convenience for people's dynamometry; Be applied in the middle school physics classroom teaching, can make the student, understand elastic deformation better by observing the working method of the utility model dynamometer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of axle of the present utility model and rotating disk.
Embodiment:
The utility model comprises base 1, base 1 is provided with riser 2 and the pillar 3 that top has index dial 7, between riser 2 and pillar 3, be provided with axle 5, on axle 5, be fixed with rotating disk 4 and corresponding to the pointer 6 of index dial 7 with coiling groove 9, link to each other with an end of cotton rope 10 in the described coiling groove 9, axle 5 links to each other with riser 2 by clockwork spring 8.
Principle of work below in conjunction with description of drawings the utility model dynamometer:
During use, on cotton rope 10, apply a power, drive rotating disk 4, axle 5 rotations, make pointer 6 deflect into a certain position; At this moment, be applied to the driving force that pulling force produced on the cotton rope 10 apart from the counter-force that is produced with clockwork spring apart from balance mutually; The data of pointer 6 shown on index dial 7 have promptly represented to be applied to the size of the pulling force on the cotton rope 10.
