Abstract
The invention discloses a kind of anti-wear ruler, including blade, the U-shaped setting of blade, the blade is additionally provided with groove in U-shaped indentation, there, the groove of the U-shaped indentation, there bottom is the first groove, the ruler also includes the scale strip that can be embedded in groove setting, and the marginal surface of the scale strip is provided with scale, and the depth of first groove is identical with the depth of 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 survey tool, more specifically, it relates to a kind of anti-wear 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 anti-wear ruler, including blade, the U-shaped setting of blade, the blade is additionally provided with groove in U-shaped indentation, there, the groove of the U-shaped indentation, there bottom is the first groove, the ruler also includes the scale strip that can be embedded in groove setting, and the marginal surface of the scale strip is provided with scale, and the depth of first groove is identical with the depth of scale.
The present invention is further arranged to：Groove of the blade in the side wall of U-shaped breach is the second groove.
The present invention is further arranged to：The bottom of first groove is provided with the first magnet, and the bottom of second groove is provided with the second magnet, and the bottom of the scale strip side wall and scale strip is provided with magnet.
The present invention is further arranged to：The width of the scale strip is identical with the length at the top of the bottom to U-shaped blade of the first groove.
By using above-mentioned technical proposal, what ruler played main function in drawing, measurement is exactly scale strip part, in the present invention, when ruler works, scale strip can coordinate the groove on U-shaped blade, scale strip can be embedded on blade, will be faced out with graduated one, and this makes it possible to the work for completing mapping.And after the completion of, scale strip is extracted out of groove, and will be inwardly inserted into graduated one side in groove, such scale would not be directly exposed to the outside of ruler.So as to serve the effect of protection to the scale of ruler so that the service life of whole ruler is more permanent.
Brief description of the drawings
Fig. 1 is the front view of the anti-wear ruler of the present invention；
Fig. 2 is the section three-dimensional map of the anti-wear ruler blade of the present invention.
In figure：1st, blade；2nd, scale strip；3rd, the first groove；4th, the second groove；5th, the first magnet；6th, the second magnet.
Embodiment
A kind of anti-wear ruler embodiment of the present invention is described further referring to figs. 1 to Fig. 2.
A kind of anti-wear ruler as depicted in figs. 1 and 2, is substantially made up of blade 1 and the two large divisions of scale strip 2.The length of scale strip 2 is arranged to 20cm, and is provided with scale at a line edge on its surface.Two lateral edges of scale strip 2 are further provided with the second magnet 6, edge of the scale strip 2 away from scale is provided with the first magnet 5.And the part of blade 1 setting of the anti-wear ruler of the present invention is as follows, whole blade 1 is arranged to U-shaped, in the indentation, there of U-shaped blade 1, opens up fluted.And the groove of the U-shaped indentation, there bottom of blade 1 is called the first groove 3, the groove of the U-shaped indentation, there side wall of blade 1 is called the second groove 4.First groove 3, the second groove 4 bottom with scale strip 2, the lateral edges of scale strip 2 respectively.And it is internally provided with the first magnet 5 and the second magnet 6 in the first groove 3 and the second groove 4., can be by the attraction between magnet and magnet, so as to reach better fixed effect thus when scale strip 2 is inserted in groove.In the present embodiment, the depth of the first groove 3 is identical with the depth of scale, and after being finished in mapping, scale strip 2 is extracted, and when changing one side insertion groove, scale can completely be hidden into inside grooves.So as to play the protective effect to the figure of scale strip 2, the use for making ruler more permanent is reached with this.
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.
