Abstract
A reusable paper tape with a scale comprises the reusable paper tape with the scale (3) and a circular graphite manifolding tablet (4). The reusable paper tape with the scale is characterized in that: there are scales on the reusable paper tape with the scale (3); one side of the reusable paper tape with the scale (3) is provided with a film; a printing film is the circular graphite manifolding tablet (4); a ticker-tape timer hits a graphite point on the reusable paper tape with the scale (3); the position of the point can be directly read on the reusable paper tape with the scale (3); after data is read, the reusable paper tape with the scale (3) can be used again through removing the point by using an eraser. The reusable paper tape with the scale has the following advantages that: an experiment principle can be improved; an experiment effect is good; reading is accurate; paper can be saved; needed equipment is less.
Description
Technical field
The present invention relates to a kind of senior middle school physics teaching experiment apparatus, be specifically related to the reusable paper tape of a kind of band scale.
Background technology
In the experiment of high school physics dotted timer, dotted timer is with blueness or black carbon paper, and the point of stamping is not easy to remove, so paper tape is maximum with twice, and dotted timer experiment paper using amount is surprising.The school of 40 teaching classes, per tour 56 people divide 28 experimental group; Each experimental group will be obtained 8 effective experimental datas, often will play 6 paper tapes, and a paper tape is grown 1 meter; Wide 1.8 centimetres, one takes turns experiment needs 121 square metres on paper tape, is equivalent to 16 and opens 2530 on paper; High school physics dotted timer experiment at least 4 is taken turns, and consume 16 and open 10120 on paper, this shows the order of severity that paper consumes.For making the student form good saving and hygienic habit, accomplish that the dotted timer experiment consumes with paper zero, so this invention is arranged.
Summary of the invention
The objective of the invention is provides a kind of band scale reusable paper tape to above-mentioned deficiency.
Solution of the present invention realizes through following technological means: the reusable paper tape of a kind of band scale comprises the reusable paper tape of band scale, circular graphite manifolding sheet.It is characterized in that: on the reusable paper tape one side of band scale scale is arranged, the another side of the reusable paper tape of band scale has film, has equadag coating, circular graphite manifolding sheet central authorities that circular port is arranged on the circular graphite manifolding sheet.
Embodiment: the one side at common paper tape is sticked film, stamps a millimeter scale in proportion at another side and makes band scale reusable paper tape, graphite is coated in form equadag coating on the circular paper and do circular graphite manifolding sheet.With being with the reusable paper tape of scale to pass the spacing hole of dotted timer, graduated one faces up, and is enclosed within circular graphite manifolding sheet on the locating shaft of dotted timer again; There is one of equadag coating to face down, is pressed on the reusable paper tape of band scale, start dotted timer; The reusable paper tape of pulling band scale; Just get some grey spots on the band scale reusable paper tape, the position of point can directly be read, and runs through the reusable paper tape of band scale after the data; Point mark is wiped with rubber on it, can reuse.If it is unintelligible that the point of getting becomes, the locating shaft of circular graphite manifolding sheet from dotted timer taken off, scribble on circular graphite manifolding sheet with pencil, can repair the equadag coating of circular graphite manifolding sheet.
Advantage: 1. the film of the reusable paper tape one side of band scale has the effect of protection paper tape; The point mark of beating on the reusable paper tape of band scale can be cleaned out; Thereby the reusable paper tape of band scale can be reused; Circular graphite manifolding sheet also can conveniently be repaired, so realize consuming with paper zero; 2. millimeter rule and the reusable paper tape of band scale are combined, both reduced personal error, make accuracy of reading, reduced instrument quantity again; 3. substitute black-and-blue soft manifolding sheet with circular graphite manifolding sheet, reduced the friction between band reusable paper tape of scale and the circular graphite manifolding sheet, improved experimental precision; 4. be with the scale on the reusable paper tape of scale; Be the length that do not receive pulling force by band scale reusable paper tape and receive length behind the tensile than stamping; Dotted timer is at the reusable paper tape of band scale to be got ready under the extended state on the scale that is stretching; After taking off the reusable paper tape of band scale, band reusable paper tape of scale and scale all recover former length, are in the scale position when stretching but the position of point still remains on the reusable paper tape of band scale; So experimental principle is perfect, measure more science.
Description of drawings
Fig. 1 is the reusable paper tape result of use of band scale figure.
Fig. 2 is a circular graphite manifolding sheet sectional view of the present invention.
Wherein: 1-dotted timer base, 2-spacing hole, the reusable paper tape of 3-band scale, the circular graphite manifolding of 4-sheet, 5-circular port, 6-equadag coating.
Embodiment
Below in conjunction with description of drawings and embodiment the present invention is made further detailed description:
The reusable paper tape of a kind of band scale comprises the reusable paper tape of band scale 3, circular graphite manifolding sheet 4.It is characterized in that: on reusable paper tape 3 one sides of band scale scale is arranged, reusable paper tape 3 another sides of band scale have film, have equadag coating 6, circular graphite manifolding sheet 4 central authorities that circular port 5 is arranged on the circular graphite manifolding sheet 4.
One side at common paper tape is sticked film; Stamp a millimeter scale in proportion at another side and make the reusable paper tape 3 of band scale; The ratio of the scale on the scale on the band scale reusable paper tape 3 and the master scale chi is by the decision of paper tape elasticity, graphite is coated in form equadag coating 6 on the circular paper and do circular graphite manifolding sheet 4.
As shown in Figure 1, with being with the reusable paper tape 3 of scale to pass the spacing hole 2 of dotted timer, graduated one faces up; Be enclosed within circular graphite manifolding sheet 4 on the locating shaft of dotted timer again, have one of equadag coating 6 to face down, be pressed on the reusable paper tape 3 of band scale; Start dotted timer, the reusable paper tape 3 of pulling band scale is just got some grey spots on the reusable paper tape 3 of band scale; The position of point can directly be read; Run through the reusable paper tape 3 of band scale after the data, some mark is wiped with rubber on it, can reuse.If it is unintelligible that the point of getting becomes, the locating shaft of circular graphite manifolding sheet 4 from dotted timer taken off, scribble on circular graphite manifolding sheet 4 with pencil, can repair the equadag coating 6 of circular graphite manifolding sheet 4.
The above; Be merely a part of embodiment of the present invention, protection scope of the present invention is not limited thereto, and any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
