Description

A kind of curve measuring tool

Technical field

This utility model relates to survey tool technical field, especially relates to a kind of curve measuring tool.

Background technology

More existing dimension measurement tool, the use for the measurement of Workpiece length is fairly simple, but for life Or the measurement of the length of curve often encountered in work, but rarely have preferable survey tool.When experiment curv length, tradition Way often take the thinking curved cut-off that curve carries out approximate measure, but so scheme error is relatively big, wants for some The measurement that refinement degree is high cannot meet requirement.Therefore Later development is gone out to serve and is rotated by gear mechanism, length of curve is turned Being changed to the curved measurement scheme of line measurement, it is the most also to carry out indicating graduation by gear driven pointer, and then display is measured Result.But due to its be use gear mechanism transmission principle, whole during do not only exist accidental coefficient, the most this measurement The systematic error of scheme itself is also obvious.It addition, when workpiece is carried out curved measurement, inevitably with work Part comes in contact, or produces collision, and the impact to survey tool is relatively big sometimes, not only have impact on the accuracy of measurement result, Result even in the damage of survey tool.Need badly design a kind of high to curved measurement degree of accuracy, service life length instrument.

Summary of the invention

This utility model is intended to overcome defect present in above-mentioned prior art, proposes a kind of curve measuring tool.

The technical solution of the utility model is achieved in that

A kind of curve measuring tool, including the roll shaft on support body and support body；Roll body is installed on roll shaft；Set on described support body There is handle；The internally installed enumerator having recordable roll body to rotate the number of turns of described roll body；Described handle is provided with for showing Stating roll body and rotate the display screen of the number of turns, this display screen is connected with described enumerator.

Further, described roll body surface is along the circumferential direction provided with locating slot.

Further, described handle is length-adjustable Telescopic shaft type structure.

Further, described handle outer surface is provided with anti-skidding lines.

Further, the both sides described support body being in described roll body are provided with crashproof wheel.

Further, described roll body is nylon roll body.

Further, described support body is provided with illuminator, and this illuminator includes LED illumination lamp and is LED illumination lamp The rechargeable type accumulator of power supply, the control switch of described LED illumination lamp is arranged on described handle.

Have employed technique scheme, the beneficial effects of the utility model are:

1) the invention reasonable in design, it is possible to part profile is made and measures accurately, and, setting crashproof Wheel collides the impact producing support body during can alleviating measurement, it is ensured that measurement result accurate, and effectively extends this work The service life of tool.

2) handle is length-adjustable Telescopic shaft type structure, can adjust the length of handle according to actual use needs Degree, will not occur the long or too short unworkable situation of handle, strong adaptability, it can be ensured that under any operating mode, can facilitate This instrument that utilizes measure.

3) being provided with locating slot on roll body surface on along the circumferential direction, when utilizing handle to promote roll body to roll, locating slot can To block the edge of workpiece to be measured, it is ensured that the data measured are more accurate.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only It is embodiments more of the present utility model, for those of ordinary skill in the art, before not paying creative work Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Wherein:

1-support body；2-roll shaft；3-roll body；4-handle；5-enumerator；6-display screen；7-locating slot；The anti-skidding lines of 8-；9- Crashproof take turns；10-illuminator；11-LED illuminating lamp；12-controls switch.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

A kind of curve measuring tool, as it is shown in figure 1, the roll shaft 2 included on support body 1 and support body 1；Install on described roll shaft 2 There is roll body 3；Described support body 1 connects handle 4；The internally installed enumerator 5 having recordable roll body to rotate the number of turns of described roll body 3； Described handle 4 is provided with for showing that described roll body 3 rotates the display screen 6 of the number of turns, and this display screen 6 is connected with described enumerator 5.

Above-mentioned roll body 3 surface is along the circumferential direction provided with locating slot 7, when utilizing handle 4 to promote roll body 3 to roll, and location Groove 7 can block the edge of workpiece to be measured, it is ensured that the data measured are more accurate.If there is no edge on workpiece, i.e. do not have It is available for the edge that locating slot 7 blocks, now, directly utilizing handle and promoting roll body 3 to measure, do not interfere with making of this instrument With.
