Abstract
The utility model relates to measuring rulers and particularly relates to an arc-shaped ruler for tailoring. The arc-shaped ruler consists of an arc-shaped measuring ruler, a measuring arm a and a measuring arm b, wherein the measuring arm a is hinged to one end part of the measuring arm b, a handle a is arranged at the tail of a hinging end of the measuring arm a, a handle b is arranged at the tail of a hinging end of the measuring arm b, one end of the arc-shaped measuring ruler is fixed to the inner side of the measuring arm b, a telescoping device a is arranged at the front end of the measuring arm a, a telescoping device b is arranged at the front end of the measuring arm b, and more than two sets of graduations are formed on the arc-shaped measuring ruler. The arc-shaped ruler for tailoring, disclosed by the utility model, has the advantages that the structural design is reasonable, and the measured length can be obtained directly by using the principle of similar triangles, so that the use is convenient; when the arc-shaped ruler is not used, the arc-shaped ruler can be shortened, so that the storage is facilitated, and no space is occupied; and during measurement, the arc-shaped ruler can be telescoped according to length needs so as to facilitate measurement.
Description
Technical field
The utility model relates to a kind of dip stick, relates in particular to a kind of cutting out and uses the arc chi.
Background technology
Ruler is kind of a requisite instrument in cloth-cutting; what mostly use all is ruler; but the ruler of cutting out usefulness is usually long; use inconvenience; also relatively clumsy during use, a people is difficult to finish the work of cutting out of measuring sometimes, with ruler be designed to shorter and smaller after; avoid above-mentioned drawback, but when measuring, often had error.
The utility model content
The utility model is intended to for the deficiency that exists in the background technology, and a kind of the cutting out that proposes used the arc chi.
A kind of cutting out of the present utility model used the arc chi, by the arc gage, gage beam a and gage beam b consist of, the end of its gage beam a and gage beam b is hinged, gage beam a hinged end afterbody is provided with handle a, gage beam b hinged end afterbody is provided with handle b, be fixed wtih an end of arc gage in the inboard of gage beam b, the front end of gage beam a is provided with retractor device a, the front end of gage beam b is provided with retractor device b, the arc gage is provided with the above scale of two covers, and retractor device a place is provided with locking device a on gage beam a, retractor device b place is provided with locking device b on gage beam b.
A kind of cutting out of the present utility model used the arc chi, reasonable in design, utilize the principle of similar triangles, can directly obtain the length measured, use conveniently, it can be shortened when not using, conveniently deposit, do not take up space, can be according to the needs of length that it is flexible when measuring, be convenient to measure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Use the arc chi below in conjunction with 1 pair of a kind of cutting out of the present utility model of accompanying drawing, be described further.
A kind of cutting out of the present utility model used the arc chi, by arc gage 1, gage beam a2 and gage beam b3 consist of, the end of its gage beam a2 and gage beam b3 is hinged by jointed shaft, gage beam a2 hinged end afterbody is provided with handle a4, gage beam b3 hinged end afterbody is provided with handle b5, be fixed wtih an end of arc gage 1 in the inboard of gage beam a2 or gage beam b3, the front end of gage beam a2 is provided with retractor device a6, the front end of gage beam b3 is provided with retractor device b7, arc gage 1 is provided with the above scale 8 of two covers, and retractor device a6 place is provided with locking device 9 on gage beam a2, retractor device b7 place is provided with locking device b10 on gage beam b3.The retractor device of this device can as required, be set with a plurality of retracting cylinders.
During use, open gage beam a2 and gage beam b3, according to the length that will measure, the length that the different retracting cylinder of arm front end is cut in selection, the retracting cylinder correspondence of different length scales different on the arc gage 1; The scale 8 of arc gage 1 directly shows is two to cut the distance between the arm front end, convenient directly perceived.
