Abstract
The utility model relates to a kind of physics educational apparatus, in particular to a kind of compression volute spring stiffness factor experimental provision, comprise volute spring, weight hook, transparent sleeve, fixed plug, triangle link, the low side of described transparent sleeve has the bottom surface with its sidewall strong construction, and bottom center's perforate is convenient to weight and is linked up with that straight upper part is smooth and easy to be passed through; It is characterized in that volute spring vertically puts into transparent sleeve, weight hook upper end and helical spring upper end are linked together by fixed plug, and the upper end of transparent sleeve is provided with triangle link.During this application of installation, be still the mode pulled by two ends, but obtain the compression set of spring, greatly facilitate student and adopt hook code to execute the experimental implementation heavily exploring its deformation quantity rule, filled up in Physical Experiment the blank lacking the experimental provision probing into spring-compressed deformation stiffness factor.The utility model structure is simple, is easy to implement, remarkably productive.
Description
Technical field
The utility model relates to a kind of physics educational apparatus, particularly a kind of compression volute spring stiffness factor experimental provision.
Background technology
Always, in Middle School Physics class in order to verify that the experiment of Hooke's law is all the method with measuring spring elongation.No matter spring is stretched or is compressed, the elastic force produced all direct proportionality same with its deformation quantity.Because there is no the experimental provision using compression method measuring spring Deformation Law easily at present, so student experimenting can only use elongation method.General is emphasize that the spring by compressing meets Hooke's law equally by teacher is oral in passing when saying elongation method on classroom, namely has the deformation phenomenon of stiffness factor.And the pedagogical experience of instructors thinks that elongation method and compression method are all necessary, student only starts to carry out fully, comprehensively testing, the content marrow of ability profound understanding rudimentary knowledge.But compression method is but the blank of current student experimenting.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design, a kind of compression volute spring stiffness factor experimental provision easy to use.
The technical scheme that the utility model adopts for achieving the above object is: a kind of compression volute spring stiffness factor experimental provision, comprises volute spring, weight hook, transparent sleeve; It is characterized in that weight hook upper end and helical spring upper end link together; Impose gravity to hook, namely spring is compressed; In addition, when being compressed to prevent spring, produce transverse curvature deformation, so spring is placed in circular non-opaque sleeve, the deformation quantity that such structure can make student carry out when measuring spring is compressed easily.
The beneficial effects of the utility model are: its structure is simple, is easy to implement, remarkably productive.During this application of installation, be still and pull by two ends the compression set but obtaining spring, greatly facilitating student adopts hook code to execute the experimental implementation heavily exploring its deformation quantity rule, has filled up in Physical Experiment the blank lacking the experimental provision probing into spring-compressed deformation stiffness.The utility model easily forms product scale, standardized production.
Accompanying drawing explanation
The cut-open view of Fig. 1, the utility model structure;
The cut-open view of a kind of application structure of Fig. 2, the utility model;
Fig. 3, the utility model transparent sleeve three-view diagram.
In figure: 1 volute spring, 2 weight hooks, 3 transparent sleeves, 4 fixed plugs, 5 triangle links, 6 hook codes.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the embodiment, the structure that provide according to the utility model, details are as follows for feature:
As shown in FIG. 1 to 3, a kind of compression volute spring stiffness factor experimental provision, comprise volute spring 1, weight hook 2, transparent sleeve 3, fixed plug 4, triangle link 5, the low side of described transparent sleeve 3 has the bottom surface with its sidewall strong construction, and bottom center's perforate is convenient to weight and is linked up with that 3 straight upper part are smooth and easy to be passed through; It is characterized in that transparent sleeve 3 vertically put into by volute spring 1, the upper end that weight links up with 2 upper ends and volute spring 1 is linked together by fixed plug 4.
Whole device is hung by the triangle link 5 being hooked in transparent sleeve 3 upper end, and weight hook 2 imposes gravity with weight such as hook code 6 grade to hook and pulls volute spring 1 upper end, namely volute spring 1 is compressed, as Fig. 2.
Transverse curvature deformation is produced when transparent sleeve 3 can prevent spring from being compressed.Its outer wall direct-axis to the even scale mark of delineation, the deformation quantity when VTOL (vertical take off and landing) position in conjunction with fixed plug 4 upper surface can represent that volute spring 1 compresses.
Above-mentioned detailed description of a kind of compression spiral spring stiffness factor experimental provision being carried out with reference to embodiment; illustrative instead of determinate; various different specification can be made as required; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
