Abstract
The utility model discloses an abrasionproof decreases ruler, which comprises a ruler body, the blade is the setting of U type, the recess is located still to be provided with at U type breach by the blade, the recess of U type breach department bottom is first recess, but the ruler still includes the scale strip that embedded Groove set up, the surperficial edge of scale strip is provided with the scale, the degree of depth of first recess is the same with the degree of depth of scale. The utility model provides an enough avoid the scale wearing and tearing, have more permanent life's ruler.
Description
Technical field
The utility model relates to a kind of survey tool, and more particularly, it relates to a kind of anti-wear ruler.
Background technology
Ruler is a kind of survey tool common in life.Be commonly used to the measurement carrying out adjusting the distance or mapping, be widely used in the fields such as mathematics, measurement, engineering.
And ruler on the market, structure is all comparatively simple.General ruler is all elongated rectangular shape shapes, and the edge on its surface is provided with scale, in specifically using, more facilitate reading.This traditional ruler is after having used of a specified duration, and the scale being positioned at its surface will be worn, and such user just cannot use this ruler clearly to carry out and measure or draw, and causes the trouble in use procedure.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide one to avoid scale-wearing, has the ruler in more permanent service life.
For achieving the above object, the utility model provides following technical scheme: a kind of anti-wear ruler, comprise blade, the U-shaped setting of described blade, described blade is also provided with groove in U-shaped indentation, there, and the groove bottom described U-shaped indentation, there is the first groove, and described ruler also comprises the scale strip that can embed groove and arrange, the marginal surface of described scale strip is provided with scale, and the degree of depth of described first groove is identical with the degree of depth of scale.
The utility model is set to further: the groove of described blade on the sidewall of U-shaped breach is the second groove.
The utility model is set to further: the bottom of described first groove is provided with the first magnet, and the bottom of described second groove is provided with the second magnet, and the bottom of described scale strip sidewall and scale strip is provided with magnet.
The utility model is set to further: the width of described scale strip is identical to the length at U-shaped blade top with the bottom of the first groove.
By adopting technique scheme, what ruler played Main Function in drawing, measurement has been exactly scale strip part, in the utility model, when ruler work, scale strip can coordinate the groove on U-shaped blade, scale strip can be embedded on blade, graduated one side will be with outside, this makes it possible to the work of mapping.And after completing, scale strip is extracted in groove, and graduated one side will be with inwardly to insert in groove, such scale would not be directly exposed to the outside of ruler.Thus the scale of ruler is served to the effect of protection, make the service life of whole ruler more permanent.
Accompanying drawing explanation
Fig. 1 is the front view of the anti-wear ruler of the utility model;
Fig. 2 is the section three-dimensional map of the anti-wear ruler blade of the utility model.
In figure: 1, blade; 2, scale strip; 3, the first groove; 4, the second groove; 5, the first magnet; 6, the second magnet.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, a kind of anti-wear ruler embodiment of the utility model is described further.
The anti-wear ruler of one as depicted in figs. 1 and 2, is made up of blade 1 and scale strip 2 two large divisions substantially.The length of scale strip 2 is set to 20cm, and an edge on its surface is provided with scale.Further two lateral edges of scale strip 2 are provided with the second magnet 6, at scale strip 2, the edge of scale are provided with the first magnet 5.And blade 1 part of the anti-wear ruler of the utility model arranges as follows, whole blade 1 is set to U-shaped, in the indentation, there of U-shaped blade 1, offers groove.And the groove bottom the U-shaped indentation, there of blade 1 is called the first groove 3, the groove of the U-shaped indentation, there sidewall of blade 1 is called the second groove 4.First groove 3, second groove 4 respectively with the bottom of scale strip 2, the lateral edges of scale strip 2.And the first groove 3 and the second groove 4 inside are provided with the first magnet 5 and the second magnet 6.So just when scale strip 2 inserts in groove, by the attraction between magnet and magnet, thus better fixed effect can be reached.In the present embodiment, the degree of depth of the first groove 3 is identical with the degree of depth of scale, this makes it possible to, after mapping is complete, be extracted by scale strip 2, and when changing one side insertion groove, scale can be hidden into inside grooves completely.Thus the protective effect played scale strip 2 figure, reach with this use making ruler more permanent.
The above is preferred embodiment of the present utility model, under not departing from the prerequisite of the utility model principle to those skilled in the art, can also make some modification and improvement, and these also should be considered as the protection domain of utility model.
