Abstract
The utility model provides an S-shaped ruler. The S-shaped ruler comprises a metal core strip which is provided with graduations and used to measure length of articles, and a transparent sleeve glue layer which is wrapped on the outer wall of the metal core strip. The S-shaped ruler has the advantages of being stable in structure, easy to manufacture, convenient to use and the like.
Description
Technical field
The utility model relates to the drawing instrument field, is specifically related to a kind of Stability Analysis of Structures, makes snakelike chi easy, convenient reading.
Background technology
Snakelike chi claims again snake chi, curve template, is one of drawing instrument, adds the software chi that flexible metal core bar is made for a kind of in the middle of the very strong material of plasticity, is similar to tape measure, the tape of thickening, can freely be put into various arc shapes, and can fix.But its curvature is quite high, and is general for drawing non-round free curve.When trace, make first the point of sufficient amount on it, with the distortion of snakelike chi, make the point of its series connection diverse location, tightly by after just available pen draw sleekly curve along snakelike chi.Except snakelike chi, can also adopt curve ruler when drawing this type of curve.Snakelike chi indicates scale at curved edge in addition, also can be used for measuring arc length, but because its precision is not high, and skewness, have certain error.Snakelike chi is widely used in the industries such as the fine arts, engineering, design, clothes, irregular curves such as the building in designing and mapping, road, pond all should adopt snakelike chi to draw, existing snakelike chi adopts three cover plastic structure, make the chi core be fixed in three around cover glue in, structural instability easily comes off, simultaneously, existing snakelike chi adopts the single face graduated structure more, is not easy to measure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Stability Analysis of Structures, makes snakelike chi easy, convenient reading.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: snakelike chi comprises that mark is graduated for measuring metal-cored of object length, being wrapped in the transparent contact adhesive layer of metal-cored outer wall.
As preferably, described contact adhesive layer adopts the structure of closed metal core bar four sides outer wall, thereby makes metal-cored to be fixed in the contact adhesive layer, has avoided the appearance of metal-cored the problem such as come off, thereby has prolonged the service life of snakelike chi.
As preferably, described metal-cored the two-sided scale that is equipped with, thus make user's reading when measuring convenient.
Beneficial effect:
The snakelike chi that the utility model adopts technique scheme to provide, is made easyly at Stability Analysis of Structures, can make operator's reading when measurement data convenient.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is rearview of the present utility model;
Fig. 3 is left view of the present utility model.
Among the figure, contact adhesive layer 1, metal-cored 2, scale 3.
The specific embodiment
As Figure 1-3, snakelike chi, comprise indicate scale 3 be used for to measure metal-cored 2 of object length, be wrapped in the transparent contact adhesive layer 1 of metal-cored 2 outer walls, described contact adhesive layer 1 adopts the structure of closed metal core bar 2 four sides outer walls, described metal-cored the 2 two-sided scales 3 that are equipped with.
When trace, make first the point of sufficient amount on the curve, again with the distortion of snakelike chi, make the point of its series connection diverse location, tightly by after just available pen draw sleekly curve along snakelike chi, length of curve all can be read in snakelike chi both sides.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as contact adhesive layer 1, metal-cored 2, scale 3, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
