Abstract
The utility model relates to a double-face ruler with continuous calibration. A first ruler face is provided with a first calibration with dimensional unit, and the calibration starts from zero. The second ruler face on the back of the first ruler face is provided with a second calibration, and the second calibration has the same dimensional unit with the first ruler face. The utility model is characterized in that the super starting number of the second calibration is the last number of the back end of the first calibration. The number of the second calibration of the second ruler face is the continuation of the first calibration number.
Description
The utility model relates to a kind of chi tool, particularly relates to a kind of two-sided chi tool with continuity scale.
The chi tool has finding more in people's daily life, and indispensable especially in some industries, as tailor, carpenter, cement worker ... Deng, the chi tool is the indispensable instrument in order to the measurement size, so, in people's life, have importance to a certain degree.
The development of chi tool, because of the prosperity of material science becomes more diverse, early stage chi tool is taken from nature material, as bamboo and wood ... Deng, the cloth matter chi tool that uses as for the tailor has then appearred; Equally, because the progress of process technology, day to today, carpenter, cement worker or decorate industry, then use tape measure, its advantage is can bounce back in time spent not, can measure when pulling out.
The use of chi tool, except that the trickleer measurement of the work of researchist or factory personnel, still having very most is the measurement of large-size or distance, as upholster or carpenter is example, and have scale with present tape measure single face, when the maximum that surpasses tape measure measures size, must remake measurement for the second time usually, then again with measure for twice the size addition after, obtain overall dimensions length.Cloth measure, it has two-sided sign, and it simultaneously is a metric system, and another side is made in Great Britain, shows the not scale of commensurate, but all is by zero beginning.So, if when surpassing length, also must do to measure for the second time, again summation is obtained total length mutually.
This mode row year arranged, though can reach basic measuring function, maximum defective is length (wherein the being full chi length for the first time) addition with twice measurement, to being bad at the people of mathematics, must take a little times, and can't write down or pass through the calculation of paper or computing machine when measuring usually.So, the operation mistake distortion except that may cause the time, also therefore expend time in because of addition, can be rated as the blemish in an otherwise perfect thing of chi tool.
The utility model purpose is to overcome many defectives that above-mentioned chi tool exists, and a kind of two-sided chi tool with continuity scale is provided.
Embodiment of the present utility model is as follows:
The two-sided chi tool with continuity scale that the utility model provides has one first chi face and one second chi face, first scale that on the first chi face, has dimensional units, and this scale is from zero beginning; On the second chi face at the first chi face back side, also has second scale with the first chi face same size unit;
The initial figure that it is characterized in that the second scale starting point is the last figure of the end of first scale, and the figure of second scale of the second chi face is the continuity of the first scale figure; The dimensional units of first scale and second scale is one or more; Scale wherein is meant the sign of executing on the chi face; The chi tool can be steel ruler, cloth measure and tape measure; The dimensional units of chi tool can be metric system, English system, platform system or master craftsman of the Spring and Autumn period unit.
The utility model advantage is: can directly obtain reading when measuring, this existing chi tool must be a quantum jump through computing.The long tape measure of 5m for example, can be bigger on the volume, if but in mode of the present utility model, the long tape measure of 5m, only need make the long tape measure of 2.5m can be effective, so just can be less on the volume, the user can be convenient for carrying, and because of alleviating of weight lighter and handier, on the other hand on making, material uses and reduces and the cost reduction, and price also lowers thereupon, and this is that existing chi tool is incomparable.
Further describe utility model below in conjunction with drawings and Examples.
Fig. 1 is the first chi face stereographic map of the present utility model.
Fig. 2 is the second chi face stereographic map of the present utility model.
The figure number explanation:
The first chi face, 1 second scale, 11 second chi faces 2
Second scale 21
As shown in the figure, basically, the two-sided chi tool with continuity scale that the utility model provides has one first chi face 1 and one second chi face 2.
Wherein, first scale 11 of size degree unit is arranged on the first chi face 1, this first scale 11 can have at least a kind of according to the difference of unit, as metric system, English system, platform system or be that other are as the carpenter's square scale.In addition, also can be two or more unit scale arranged side by side, as metric system, English system, and is different colours, in order to interpretation.The figure of first scale 11 of this first chi face 1 is by zero beginning, and begins expansion according to the maximum size that measures of the single of chi tool by zero, as to 3 meters or 5 meters ... or the like.This is a prior art all, so will not give unnecessary details.Its scale, except that for engraving, also available as printing ... make etc. mode.
The utility model is characterised in that the second chi face 2, as shown in Figure 2, has second scale 21 on the second chi face 2, this second delineation, initial number of 21, be not as the first chi face 1 by zero beginning, but be initial by the figure of the maximum length of the first chi face 21, when being 5 meters as first scale 11 of the first chi face, 1 end, then 21 of the start index of the second chi face 21 are 5 meters, and according to the expansion of physical size number, can be to 10 meters.The identical scale units of first delineation 11 of second scale 21 and the first chi face 1, as meter, foot, platform chi, it is arranged side by side also to can be two kinds or above unit, as meter with foot.
Please consult diagram again, when the utility model is implemented in reality, when the length of required measurement during greater than the single measurement size of chi tool, then measure with the first chi face 1 in advance, and at its terminal maximum number place, again with this chi tool turn-over, starting point with the second chi face 2 falls within this place, and the stretching second chi face 2, then should be measured thing be by gauge point the total length that this is measured thing corresponding to the figure of second scale 21 of the second chi face 2, so, promptly must directly not obtain the length that measured through the overwriting computing.
What the utility model disclosed, a kind of for preferred embodiment, Ju Bu change or modification and come from technological thought of the present utility model and be to know this technical field personnel to be easy to know by inference such as all do not break away from the utility model rights protection scope.
