Abstract

The utility model discloses a double-tape flexible rule which comprises a rule box, a long tape and a short tape. The long tape and the short tape are both arranged in the rule box, and the long tape is located below the short tape. Scale marks are respectively arranged on the long tape and the short tape, a through hole is respectively arranged at the center of each scale mark of the long tape, a positioning buckle is fixedly arranged at the zero scale mark position of the short tape and can be inserted into the through holes of the long tape, and the axis of the positioning buckle and the scale marks at the positions of the through hole of the long tape are overlapped. According to the double-tape flexible rule, the machining method is adopted for the long tape, and the manufacture accuracy of the long tape is easy to control due to the fact that the machining accuracy is far higher than the printing accuracy. The planographic printing or the electro erosion process after plate making is adopted for the scale marks of the short tape, so that the short tape is easy to manufacture and can be controlled easily in accuracy. The double-tape flexible rule can be manufactured by aid of general small machinery instead of the traditional special printer used for producing steel flexible rules.

Description

A kind of pair of chi band tape measure

Technical field

The utility model relates to a kind of tape measure, relates in particular to a kind of tape measure with two chi bands.

Background technology

Steel tape is the measurer that our daily life, building industry, manufacturing industry etc. are generally used, the conventional steel tape measure that now manufacturing enterprise's manufacturing, on the market sale, consumer use, be the steel tape of the whole continuous printing scales of whole piece chi band, the printing equipment of this quasi-tradition steel tape is huge, complicated, cost is high, and the difficult control of printing precision.Because the height of measuring accuracy directly determines the quality good or not of product, and often steel tape is as generally using one of important survey instrument, and its precision is just particularly important.

We generally use this quasi-tradition steel tape at present, its scale mark forms for printing, to making a plate in the printing process, paste version, the driving error of printing machinery, paste the morpheme error of version wheel, the accuracy requirement of the process procedures such as the morpheme error scale error of delivery wheel is all very strict, so a defective of the conventional steel tape measure maximum that we generally use is exactly that manufacture difficulty is large, the steel tape that especially will produce national standard I class precision is extremely difficult especially, and equipment investment is very huge, technical merit to the equipment operator requires quite high, on the other hand, form scale mark with typography, the degree of accuracy of scale mark generally all is difficult to reach requirement, and the very easily wearing and tearing in the use procedure of tape measure of the scale mark of printing, affected serviceable life of tape measure.

The utility model content

In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of pair of chi band tape measure, comprises chi box, long chi band, short chi band.

Described chi box comprises long chi chi box and short chi chi box, and long chi band is installed in the long chi chi box, and short chi band is installed in the short chi chi box.Described long chi band is positioned at the below of short chi band.

Have the scale mark take rice as unit on the long chi band, this scale mark is scribed by the method for machining, is groove or projection.Central authorities at every scale mark of long chi band all offer a through hole, through hole be shaped as water-drop-shaped.

Scale mark on the short chi band comprise centimetre and millimeter, electrocorrosion technique was scribed after described scale mark adopted offset printing or plate-making, was groove or projection.

0 scale mark place at short chi band is fixedly installed locating button, and locating button can insert in the through hole of long chi band, and after insertion, the axis of described locating button overlaps with the scale mark of the through hole of long chi band.

The long chi band of of the present utility model pair of chi band tape measure adopts machining process, makes the accurate location between the rice section, is aided with the short chi band of accurately measuring between the rice section again.Because the precision of machining is far above printing precision, so long chi band manufacturing accuracy is controlled easily, and the scale mark of short chi band adopts electrocorrosion technique after offset printing or the plate-making, manufactures relatively simple and easyly, and precision also is easy to control.Make the special-purpose printing machine that tape measure of the present utility model need not production conventional steel tape measure, only need general small-sized machine to finish.

According to the steel tape that the utility model manufactures and designs, can produce easily meet " People's Republic of China's light industry standard steel tape measure " (QB/T2443-99) in steel tape of I class precision.Simultaneously, press the steel tape of the utility model design, can produce the steel tape that any length, width satisfy the requirement of I class precision.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, but not as to restriction of the present utility model.

To shown in Figure 5, of the present utility model pair of chi band tape measure comprises chi box 1, long chi band 2, short chi band 3 such as Fig. 1.

Chi box 1 comprises long chi chi box 11 and short chi chi box 12, and long chi band 2 is installed in the long chi chi box 11, and short chi band 3 is installed in the short chi chi box 12.Certainly, it will be recognized by those skilled in the art that long chi chi box 11 and short chi chi box 12 can separate, also can be integrally formed, also can unite two into one, form a chi box 1, long chi band 2 and short chi band 3 all are arranged in the chi box 1, and long chi band 2 is positioned at the below of short chi band 3.

Such as Fig. 4, shown in Figure 5, have the scale mark 21 take rice as unit on the long chi band 2, namely long chi band 2 is take rice as minimum measuring unit.Scale mark 21 is scribed by the method for machining, and described scale mark 21 is groove or projection.The precision of the scale mark that the method by machining obtains will be far above the precision of the scale mark that obtains by mode of printing.Central authorities at every scale mark of long chi band 2 all offer a through hole 22, through hole 22 be shaped as water-drop-shaped.

Scale mark on the short chi band 3 comprise centimetre and millimeter, namely short chi band 3 is take millimeter as minimum measuring unit.Electrocorrosion technique was scribed after described scale mark adopted offset printing or plate-making, was groove or projection.

Such as Fig. 2, Fig. 3, shown in Figure 5, be fixedly installed locating button 4 at 0 scale mark place of short chi band 3, locating button 4 is " worker " font, and its middle part is right cylinder.Locating button 4 can insert in the through hole 22 of long chi band 2, and the cylindrical axis of locating button 4 overlaps with the scale mark at through hole 22 places of long chi band 2.

As shown in Figure 2, of the present utility model pair of chi band tape measure in use, for example the length of object to be measured is 2.5 meters, use first long chi band 2 to measure, because 3 meters of object less thaies, therefore need to re-use short chi band 3, through hole 22 places that the locating button 4 of short chi band 3 is inserted 2 meters scale marks of long chi band 2 are with remaining 0.5 meter of short chi band 3 measurements.

It should be noted that; the above only is preferred embodiment of the present utility model; be not so limit scope of patent protection of the present utility model, the utility model can also carry out to the structure of above-mentioned various parts the improvement of material and structure, or adopts the technical equivalents thing to replace.So the equivalent structure that all utilizations instructions of the present utility model and diagramatic content are done changes, or directly or indirectly apply to other correlative technology fields and all in like manner all be contained in the scope that the utility model contains.
