Abstract

The utility model relates to a bidirectional graduation dynamometer, and in particular relates to a tensometer, belonging to measurement tools. The tensometer is provided with two rows of graduated scales with same graduations, fonts for numbers of the graduated scales have reverse directions, and in addition, a fluorescent paint is coated on a graduation panel of the tensometer. With the adoption of the bidirectional graduation dynamometer, positive numbers can be seen whether the bidirectional graduation dynamometer is pulled upwards or downwards, and the numbers can be read in dim lights, so that a measurement value is convenient to observe under different measurement conditions, and an error due to unaccustomedness in observation directions is reduced.

Description

The centre zero scale dynamometer

Technical field

The utility model belongs to field of measurement, relates to a kind of tautness meter.

Background technology

Tautness meter and spring balance can be measured pulling force or weight, on utensil, all indicate digital calibration, and when measuring weight, power is in vertical direction, and digital calibration all is in normal direction of observation; The environment when but dynamometer uses is very complicated, and when measuring pulling force, pulling force can be an any direction; Like the Physical Experiment in school, when measuring power big or small with the spring tension meter through pulley, power possibly be any direction; Digital calibration on the spring tension meter often is in improper direction of observation, and at this moment not only reading is difficult, also misunderstands numeral arbitrarily; Cause very mistake, make experimental result mistake occur.Have, daylighting is well very important for reading again, the complicacy of environment during still owing to use, and the index dial of dynamometer is backlight often, can cause the reading difficulty of insufficient light like this.

Summary of the invention

The utility model provides a kind of two-way tape graduated dynamometer, makes dynamometer no matter be in which direction, and the dynamometer of seeing the peek word near normal direction can be arranged, and adopts fluorescent scale, to overcome the problems referred to above.

To achieve these goals, the utility model has designed the centre zero scale dynamometer, is made up of tautness meter; On the scaleplate of said tautness meter, scribble fluorescent paint; And two row's scales about being provided with, this two rows scale is the mirror image symmetry each other, and the designation number in two row's scales also is symmetrically arranged.

The words direction of the designation number of said two row's scales is that symmetry is inboard towards tautness meter.

The words direction of the designation number of said two row's scales is that symmetry is towards the tautness meter outside.

The words direction of designation number of said two row's scales is along the longitudinal direction of tautness meter.

Said scale is the scale that is imprinted on the blank sheet of paper of gum, can the scale on the blank sheet of paper that be imprinted on gum directly be attached to the opposite of the scale of original single face tautness meter like this, forms the dynamometer in the utility model.

The advantage of the utility model is: owing to be provided with the designation number of positive and negative both direction, making dynamometer no matter be in which kind of direction can have near being in dromic numeral and can observe; And the scale panel scribbles fluorescent paint, even make dynamometer under dim environment, also can see scale clearly.

Fig. 2 is the utility model centre zero scale dynamometer preferred embodiment 2 synoptic diagram;

Fig. 3 is the utility model centre zero scale dynamometer preferred embodiment 3 synoptic diagram.

Embodiment

The utility model such as Fig. 1-3 is said, is made up of spring and index dial, and the pointer on the spring adopts four-headed arrow; Index dial is provided with the double scale in the left and right sides, and scribbles fluorescent paint on the index dial.

The utility model also can obtain with existing spring tension meter processing, for example:

1. take existing spring tension meter scale (side of strong scale) photo with digital camera, and deposit computer in.

2. use ACDSee9.0 software adjustment photo size, then in paint program, the numeral on the scale is selected with " selecting " instrument, and behind " upset/rotation " option in clicking " image " menu, eject " upset and rotation " dialog box.In dialog box, click " by the certain angle rotation " radio button and click " 180 degree " radio button, last click OK button.At this moment, the scale numeral overturn downwards 180 the degree.Then, change all the digital directions on the scale according to this way.

3. open a Word document, insert amended just now photo, and adjust its size, making it and the ratio of existing spring tension meter scale is 1: 1, then it is printed, and preferably uses the paper that has gum to print.

4. be cropped to suitable dimensions to the photo of the spring tension meter scale that prints.

5. hold the spring tension meter, observe the pointer location, and with marking its position,, be attached to the opposite side of scale of the dynamometry of former spring tension meter, promptly get again with the zero graduation alignment mark of the spring tension meter scale photo that cuts.

According to the direction of original spring tension count word, the reverse numeral of processing can have with several kinds:

1. like Fig. 1, numeral is along the direction of spring tension meter.

2. like Fig. 2, numeral is symmetrically towards the spring tension meter outside.

3. like Fig. 3, numeral is inboard towards the spring tension meter symmetrically.

Claims

1. the centre zero scale dynamometer is made up of tautness meter, it is characterized in that: on the pointer of said tautness meter and scale, scribble fluorescent paint, and two row's scales about being provided with, this two rows scale is the mirror image symmetry each other.

2. centre zero scale dynamometer as claimed in claim 1 is characterized in that: said scale is the scale that is imprinted on the blank sheet of paper of gum.
