Description

Tape measure with auxiliary calibration intermediate point

The utility model relates to a kind of measurer, specifically is the tape measure with auxiliary calibration intermediate point.

Measurers such as common on the market ruler, tape measure are widely used in the measurement of distance.Ruler is a sheet of elongate body, and material mostly is timber, steel etc., at two parallel edges of ruler, in modes such as engraving, etching, printings master scale is made thereon, as of of distance measure.During use, ruler is positioned over distance to be measured, poor by the visual scale that reads point-to-point transmission, and learn distance value to be measured, very convenient, the measurement distance that ruler was suitable for then is limited, be applicable to that the following short distance of 1m measures, and for measuring of longer distance, probably can't bring into play its function more.On long distance measuring, people often are used as the measurer of long distance metric by means of tape measure.Tape measure is by the made chi band of the material of tool flexibility, becomes web-like to be positioned on the interior wheel, and interior wheel is coated by Flexible rule case.When the user need make distance metric, the grab at zero point of chi band front end is pulled out, place an end hook of testing distance to live as benchmark, and with the chi band near determinand or testing distance place, poor with the visual scale that reads point-to-point transmission then, and learn distance value to be measured.With the measurer of tape measure as the measurement distance, can solve aforementioned ruler in the puzzlement that measures long distance, the master scale on the chi band is many with printing in addition, and modes such as etching are made, at two straight horizontal survey edges of chi band, be manufactured with public affairs respectively, two kinds of scales made in Great Britain use for the user.As shown in Figure 1.

In practice, to do the measuring of distance except utilizing measurer, the distance that also utilize to measure gained provides that engineering is measured, constructs, decorate, purposes such as ornaments at home.In above-mentioned every purposes, often because of actual needs, demand is got the intermediate value of the length distance of surveying, and meaning promptly seek to measure the intermediate point of distance, with as the reference of further measuring, constructing.The way that tradition is asked for intermediate value is that to read the scale that measures between distance poor by means of visual, and learn wait to measure distance value after, other uses a computer or the hand computation mode, calculates the numerical value of intermediate point position, and then calibrates intermediate point.No matter above-mentioned way is hand computation or by COMPUTER CALCULATION, all lacks its convenience, and hand computation is easier to produce error to the mathematics chump, influences its correctness; Use a computer and be engaged in calculating, need carry computing machine again, very inconvenient, in addition, use these two kinds of methods to ask for intermediate point, must suspend measurement work, through doing to reappose the action that the measurer rower is decided intermediate point again after the calculating slightly, this program is real to be loaded down with trivial details, extremely undesirable.

This shows that above-mentioned measurer still has problems and needs to improve.

The purpose of this utility model is exactly to provide a kind of tape measure with auxiliary calibration intermediate point at above-mentioned situation, the user is when being engaged in surveying work, as long as record apart from length overall, can directly on chi, obtain this numerical value apart from intermediate point, thereby saved the calculation procedure that traditional intermediate point is demarcated, simplified job step, saved time, increased work efficiency.

The technical solution of the utility model is: comprise tape measure housing, interior wheel and chi band, wheel is positioned at tape measure housing wherein, the chi tape wrapping is on interior wheel, one metric system and graduated in English respectively are set and for being the scale of the shape of rising in value gradually on chi band two parallel edges, and corresponding metric system and the intermediate point scale made in Great Britain of being provided with, the numerical value of the intermediate point scale that this correspondence is provided with just is half of master scale numerical value, and is value-added gradually form, more than the benchmark of four groups of scales all be arranged at same point zero point.

According to technique scheme, the utility model can be used different unit scales and use, when stretching chi band is engaged in measurement, the i.e. numerical value that is read by the distance length overall, the direct identical numerical value on the intermediate point scale that reads this distance on the chi band, thereby finish the measurement task of demarcating intermediate point, very simple, convenient.

Therefore, the tape measure with auxiliary calibration intermediate point that application the utility model provides compared with prior art, have the following advantages: can save the calculation procedure that traditional intermediate point is demarcated, reach the work efficiency of simplifying job procedure: can save the working time, and then increase work efficiency; And have plurality of advantages such as simple to operate.

Describe in detail below in conjunction with the embodiment accompanying drawing.

Wheel 30-chi band 32-metric system scale in the 10-tape measure housing 20-

34-graduated in English 36-intermediate point scale

Referring to Fig. 2, Fig. 3, the tape measure with auxiliary calibration intermediate point that the utility model provides mainly includes tape measure housing 10, interior wheel 20 and chi band 30.Respectively comprise a metric system scale 32 and graduated in English 34 on two parallel edges of chi band 30, and for being the scale of the form of rising in value gradually, correspondence is provided with the intermediate point scale 36 of metric system scale 32 and graduated in English 34 in addition, its scale numerical value just is half of master scale numerical value, and being value-added gradually form, the benchmark of four groups of scales all is arranged at same point zero point.

According to design of the present utility model, can use different unit scales and use.When stretching chi band 30 measures, i.e. the numerical value that is read by distance length overall D, the identical numerical value on the corresponding intermediate point scale 36 is promptly finished the measurement task of demarcating intermediate point D '.

Referring to Fig. 4, hang mural painting if desire between two fan windows, to get its intermediate point.Traditional practice be need to measure earlier between two fan windows apart from length overall D, divided by two, the numerical value that will obtain is as calculated sought scale on band tape 30 again, can finish the work of demarcating intermediate point with the numerical value that read.And the tape measure with auxiliary calibration intermediate point that application the utility model provides, can save above-mentioned loaded down with trivial details implementation step, during enforcement, directly pull out chi band 30 and be engaged in measurement, to be confirmed apart from after the length overall, read the numerical value that D is ordered, the identical numerical value on the direct corresponding intermediate point scale 36 is promptly finished the measurement of demarcating intermediate point D ', because can be without calculating, save time, and plurality of advantages such as simple to operate are arranged, practicality increases widely.
