Abstract

The utility model discloses a novel tape measure, which comprises a measure body and a chamber for containing the measure body; wherein, the measure body can be freely drawn out or withdrawn via an opening positioned on one side of the chamber; one side of the measure body is a unit length measurement system the start position of which is a zero position; the other side of the measure body is a unit length measurement system the start position of which is a non-zero position; and the marked number of the start position of the latter is strictly equal to the length between the opening and a reference measurement surface arranged on the other side of the chamber. The design effectively resolves the defect that during the measurement, the measure body of the prior tape measure possibly needs to be bent in order to avoid the interference caused by space obstruction and fulfill a measurement task; the essence of the design is that the length occupied by the whole chamber and fittings thereof in the direction of space measurement is shifted to the start position; and by setting a number equal to the datum of the start position of the total length of the chamber and the fittings thereof, the direct-read numerical value of the measure body drawn out of the chamber, which corresponds to the side of the opening, is the final needed numerical value. The tape measure not only can be used to carry out all the measurements conducted by an ordinary tape measure but also can conveniently measure an inner wall and allow direct reading.

Description

A kind of novel tape measure

Technical field

The utility model relates to a kind of dimensional measuring instrument, specifically is a kind of novel tape measure.

Background technology

Tape measure is as a kind of dimensional measuring instrument commonly used, take in conveniently owing to it carries, measurement range used greatly widely, but in the actual measurement process, no matter be the steel or the ruler of plastic material, because the restriction of measuring condition often need or fold tape measure in the bending of data collection point place, with correct relatively reading and definite required measurement data; Such as when measuring the inside dimension of a wardrobe because the stopping of cabinet baffle plate, when measuring, may bend the chi body or mark is read in setting in measuring terminals, obtain required measurement result then; Obviously of this sort way has become a kind of custom that most of people use tape measure, such operation not only makes the accuracy of measuring numerical value reduce and diminishes the tape measure life-span, if what select for use is the tape measure of steel, so folding be not to be easy to accomplish.

The utility model content

It is a kind of easy to use that technical problem to be solved in the utility model is to provide, and measures accurately the novel tape measure with two starting points.

Technical problem to be solved in the utility model is achieved through the following technical solutions.

A kind of novel tape measure, comprise chi body and the cavity that is used to take in described chi body, described chi body is freely stretched out by the gateway of described cavity one side or returns, the one side of described chi body is the unit length measurement system of non-zero for the measuring basis start bit, the sign numerical value of described start bit equals the distance of described gateway end to the set reference measurement face of described cavity opposite side, and described reference measurement face exceeds the another side of cavity gateway for the mounting article that is provided with on cavity.Such design has solved existing tape measure effectively might need to bend the deficiency that the chi body is finished measuring task in order to dodge the interference that space obstacle brings when measuring, this design is moved start bit with whole cavity and last mounting article thereof in the occupied length of measured direction in space, by the start bit data that a numerical value is equal to cavity and annex length value thereof are set, make that the represented numerical value of chi body is that the reading of ruler is exactly the actual numerical value in the space of surveying.

As the further improvement of the technical program, it is the length graduation apparatus of zero-bit that described chi body also has a measurement start bit, and described graduation apparatus is located at described tape measure one side surface.Such design can be so that this tape measure still can keep the repertoire of existing tape measure when possessing above-mentioned functions.

As the preferred embodiment of the technical program, the unit length measurement system that described measuring basis start bit is a non-zero is located at a side surface of tape measure, graduation apparatus is located at the tape measure surface helps the user and make things convenient for reading of data.

And described reference measurement face can be selected various ways, can be at tape measure upper fixed one object of cavity gateway one side, and this object exceeds the tape measure cavity length, and the outside end face of this object is as the reference measurement face.Simultaneously, the object of being fixed above the tape measure of cavity gateway one side can be folding shape object, and described folding shape object surpasses the tape measure cavity length when launching, and the outside end face when this object launches is the reference measurement face.

Adopt the tape measure of the technical program easy to use, measure accurately, can not accurately read the deficiency of measurement data when having solved existing tape measure effectively and in measuring process, running into space constraint, in the serviceable life of better having improved tape measure, expanded the function of its use.

Embodiment

How further specify the utility model below in conjunction with accompanying drawing 1-Fig. 6 realizes:

Embodiment 1

Tape measure as shown in Figure 1 to Figure 3 comprises chi body 1 and cavity 2, and chi body 1 stretches out outside the cavity 2 from the chi body gateway 21 of cavity one side, and time spent chi body can not received in cavity 2, and these and common tape measure all are similar; The characteristics of this tape measure are, except be provided with the start bit scale at a scale face is 0 the surveyors' staff, being provided with the start bit scale at another scale face 1b face is not 0 surveyors' staff, here the start index of 1b face is 8,8 unit lengths, be to determine according to inbound port 21 to the distance between the reference measurement face 22 on cavity right side that goes out in cavity left side, promptly 21 to 22 distance is a foundation of determining the initial value of the initial chi face of non-zero 1b; Reference measurement face 22 leans on corresponding measuring terminals position during measurement, and like this shown numerical value in 1b scale face and 21 joints, gateway just in time is measured correct value, thereby removes from because the restriction of measurement space need bend the shortcoming of chi body 1; And owing to also possess the graduation apparatus of 0 value start bit at another measurement face, the traditional function that makes things convenient for tape measure like this and had.

Embodiment 2

Tape measure structure as shown in Figure 4 and Figure 5, on the cavity 2 of tape measure, be provided with a folding object 23 among the figure, this folded piece 23 articulates by pivotal axis 231 and cavity 2, and when it launches (Fig. 5 is unfolding state figure), its end face 232 can serve as the reference measurement face when measuring.Corresponding initial numerical value on a side of its chi body is from the cavity gateway to end face 232 length numerical value (being the length of 9 units) herein, and shown numerical value just in time is measured actual numerical value on the chi.And also possess the graduation apparatus of 0 value start bit in chi body another side, the function of the measurement outer length that makes things convenient for tape measure like this and had.
