Description

A kind of multi-purpose telescopic ruler
Technical field
The utility model relates to a kind of multi-purpose telescopic ruler.
Background technology
Ruler is for measuring length, is widely used in the subjects such as mathematics, measurement, engineering, and its function of protractor is used for measuring angle, and horizon rule is used for mensuration level.Three has different functions, but in the field use procedures such as finishing, architectural engineering, teaching, three is often inseparable, use, carry, to preserve multiple types of tools very inconvenient, purchase multiple types of tools and need to spend more cost, manufacture multiple a large amount of instrument and also cause the waste of physical resources.The utility model is to integrate angulation lining Expansion ruler multi-functional, multipurpose, can well solve the problem of above-mentioned existence, and a chi is multiplex, multiple functional, has broad application prospects.
Utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement, and technical problem to be solved in the utility model is to provide a kind of multi-purpose telescopic ruler, not only can extend measurement length range, but also can take measurement of an angle and carry out horizontal survey.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of multi-purpose telescopic ruler, comprise shrinkage-rule, described shrinkage-rule comprises that some joints can nested flexible cover chi, the two sides dual-side of described cover chi is provided with dimension line and Digital ID, on described cover chi end, be provided with two groups of springs, the two ends of described spring are all connected with hoodle, described cover chi porch is provided with the through hole that aperture is less than hoodle external diameter on two side, described outermost layer cover chi end does not arrange spring, described innermost layer cover chi porch does not arrange through hole, described outermost layer cover chi end is hinged with angle square, the appearance and size of described angle square is identical with outermost layer cover chi, on the surface at described cover chi and the angle square place of being hinged, be provided with 360 ° of angle index lines.
Further, described angle square is provided with angle peep hole with cover chi hinged place, and a frame of described peep hole is mutually concordant with 360 ° of angle index lines in the time that angle square rotates.
Further, the two sides dual-side of described angle square is provided with dimension line and Digital ID.
Further, a sidewall middle part of described outermost layer cover chi is provided with levelling tube, and described levelling tube comprises the transparent sealing pipe that includes liquid, in described sealed tube, leaves air.
Compared with prior art, the utlity model has following beneficial effect:
1, multiplex, the diverse in function of a chi;
2, measure easy, data are accurate;
3, economical and practical, saving investment;
4, simple and direct light and handy, easy to carry.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Brief description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-shrinkage-rule, 11-through hole, 12-angle peep hole, 13-angle index line, 14-dimension line, 2-angle square, 3-levelling tube.
Detailed description of the invention
Embodiment mono-: as shown in Figure 1, a kind of multi-purpose telescopic ruler, comprise shrinkage-rule 1, described shrinkage-rule 1 comprises that six joints can nested flexible cover chi, the two sides dual-side of described cover chi is provided with dimension line 14 and Digital ID, on described cover chi end, be provided with two groups of springs, the two ends of described spring are all connected with hoodle, described cover chi porch is provided with the through hole 11 that aperture is less than hoodle external diameter on two side, described outermost layer cover chi end is hinged with angle square 2, the appearance and size of described angle square 2 is identical with outermost layer cover chi, the two sides dual-side of described angle square 2 is provided with dimension line and Digital ID, on the surface at described cover chi and angle square 2 places of being hinged, be provided with 360 ° of angle index lines 13.
In the present embodiment, described angle square 2 is provided with angle peep hole 12 with the cover hinged center of chi, one frame of described peep hole 12 is mutually concordant with 360 ° of angle index lines in the time that angle square rotates, and adopts which kind of material to make no matter this peep hole has ensured angle square, can observe angle.
In the present embodiment, the sidewall middle part of described outermost layer cover chi is provided with levelling tube 3, and described levelling tube 3 comprises the transparent sealing pipe that includes liquid, in described sealed tube, leaves air, and described liquid is glycerine or alcohol.
In the utility model is implemented, while measuring length, range estimation need to be measured the substantial distance of object, stretching shrinkage-rule 1, measures its length, while taking measurement of an angle, balanced each other in a limit at shrinkage-rule and measured angle, and balanced each other in another limit at angle square switch and measured angle, can directly observe the value for the treatment of measuring angle by angle peep hole 12, the frame reading mutually concordant with 360 ° of angle index lines in angle square peep hole Chi center is exactly surveyed angle.When mensuration level, by placed in the middle the bubble in levelling tube, determine the level of measuring or proofreading and correct object or straight line taking shrinkage-rule as horizontal line.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
