Abstract
The invention discloses a kind of ruler, including blade, rotating bars are provided with the blade, the blade is arranged to U-shaped, the both ends of the rotating bars are connected to the recess of U-shaped blade by rotating shaft, and the edge of the rotating bars is arranged to linear edge, and the edge on the rotating bars surface is provided with scale.It is an object of the invention to provide one kind can avoid scale-wearing, have the ruler of more permanent service life.
Description
Technical field
The present invention relates to a kind of detection instrument, more specifically, it relates to a kind of ruler.
Background technology
Ruler, it is a kind of common survey tool in life.The measurement or mapping adjusted the distance are commonly used to, is widely used in the fields such as mathematics, measurement, engineering.
And ruler on the market, structure are relatively simple.In general ruler is an elongated rectangular shape shape, and the edge on its surface is provided with scale, to specifically used middle enhanced convenience reading.After having used long, the scale positioned at its surface will be worn this traditional ruler, and such user just clearly can not be measured or be drawn using the ruler, cause the trouble during use.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide one kind can avoid scale-wearing, there is the ruler of more permanent service life.
To achieve the above object, the invention provides following technical scheme：A kind of ruler, including blade, rotating bars are provided with the blade, the blade is arranged to U-shaped, the both ends of the rotating bars are connected to the indentation, there of U-shaped blade by rotating shaft, and the edge of the rotating bars is arranged to linear edge, and the edge on the rotating bars surface is provided with scale.
The present invention is further arranged to：The thickness of the blade is identical with the thickness of rotating bars, and the rotating bars are rectangular-shape.
The present invention is further arranged to：Scale is provided with three surfaces of the rotating bars.
By using above-mentioned technical proposal, rotating bars can be arranged on U-shaped blade by rotating shaft, and such rotating bars can just carry out a rotation around the shaft relative to U-shaped blade.A mark when the scale on rotating bars can play ruler as measurement simultaneously.When using it is complete when rotating bars need to only be rotated, it becomes possible to the abrasion of scale strip will be reduced, with graduated one side away from desktop or paper so as to increase the service life of whole ruler well.
Brief description of the drawings
Fig. 1 is the structure chart of ruler embodiment of the present invention.
In figure：1st, blade；2nd, rotating bars；3rd, rotating shaft；4th, scale.
Embodiment
Reference picture 1 is described further to a kind of boiler embodiments of the present invention.
A kind of ruler as shown in Figure 1, including blade 1, in the present embodiment blade 1 be arranged to U-shaped, its length is arranged to 22cm, and its thickness is arranged to 0.5cm.And the U-shaped concave interior of U-shaped blade 1 is provided with a rotating bars 2, rotating bars 2 are arranged to cuboid, long 20cm, are highly disposed as 0.5cm with width.And at the both ends of rotating bars 2, it is connected to by rotating shaft 3 on blade 1.Here the wide and high setting of rotating bars 2 be 0.5cm be to be able to allow rotating bars 2 what state whether rotated to, can with whole blade 1 keep a plane, this makes it possible to using ruler when enhanced convenience, more accurately.
And in the present embodiment, in rotating bars 2 four planes for not installing rotating shaft 3, it arbitrarily have chosen on three faces, scale 4 be provided with its edge.And rotating bars 2 here are arranged to transparent, so preferably convenient use person can be good at seeing scale 4 during use.
After using ruler mapping, rotating bars 2 only need to be rotated, will not have the one side of scale 4 on rotating bars 2, put close to desktop, it becomes possible to protect the scale 4 on other three faces not to be worn.And it is to be provided with scale 4 on three faces of rotating bars 2 in the present embodiment, equivalent to there is three rulers.When the scale 4 of wherein one side is worn, or when the edge of wherein one side is damaged injustice, rotating bars 2 are rotated, it becomes possible to unaffected.Equivalent to by three ruler combinations, together, its service life is on the three times of traditional ruler.
Described above is the preferred embodiment of the present invention, to those skilled in the art without departing from the principles of the invention, can also make some variations and modifications, and these also should be regarded as the protection domain of invention.
Claims (3)
1. a kind of ruler, including blade, it is characterized in that：Rotating bars are provided with the blade, the blade is arranged to U-shaped, and the both ends of the rotating bars are connected to the indentation, there of U-shaped blade by rotating shaft, and the edge of the rotating bars is arranged to linear edge, and the edge on the rotating bars surface is provided with scale.
2. ruler according to claim 1, it is characterized in that：The thickness of the blade is identical with the thickness of rotating bars, and the rotating bars are rectangular-shape.
3. ruler according to claim 2, it is characterized in that：Scale is provided with three surfaces of the rotating bars.
