Description
Technical field
The utility model relates to a kind of survey tool, and more particularly, it relates to a kind of durable combination 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.And after the scale-wearing of traditional ruler, just need to buy new ruler and could continue mapping, trouble very, inconvenience.The purpose of this utility model is to provide one to avoid scale-wearing, has the ruler in more permanent service life.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and compares more permanent ruler in traditional ruler service life.
For achieving the above object, the utility model provides following technical scheme: a kind of durable combination ruler, comprise blade, described blade comprises at least two chi bar unit, described chi bar unit comprises the first chi bar and the second chi bar, described first chi bar and the second chi bar are overlapping setting, described first chi bar and the second chi bar are rectangular-shaped, the front end face of described first chi bar is provided with the first raised line, the rear end face of described first chi bar is provided with the first groove, the cross-sectional sizes of described first raised line, shape, the cross-sectional sizes of level height and the first groove, shape, level height is identical, the upper surface of described first raised line is provided with scale, the front end face of described second chi bar is provided with the second raised line, and the rear end face of described second chi bar is provided with the second groove, and the cross-sectional sizes of the cross-sectional sizes of described second raised line, shape, level height and the second groove, shape, level height are identical, the top of described first raised line and the second raised line is provided with magnet, and the bottom of described first groove and the second groove is equipped with magnet.
The utility model is set to further: the surface of described first raised line, the second raised line is provided with the kick in order to increase friction, and the surface of described first groove and the second groove is provided with the kick in order to increase friction.
The utility model is set to further: described chi bar cell transparent is arranged.
By adopting technique scheme, adjacent chi bar unit just by cooperatively interacting between raised line and groove, thus can be combined.When the scale-wearing on first chi bar unit, or first raised line surface fracture produce pit time, just can be dismantled, and the afterbody of last chi bar unit can be engaged in, the first raised line on chi bar unit new so has just exposed, the scale be arranged on the first raised line is just intact again, is equivalent to change one new ruler.Being provided with several chi bar unit is just equivalent to be provided with several new ruler.And after being pulled down by first chi bar unit, insert the afterbody of last chi bar unit, overall, do not affect the width of ruler, user still can be allowed to use very easily and survey and draw.And in the utility model, when ruler uses, be with graduated first raised line directly not contact paper or bottom surface, so just can reduce the wearing and tearing to the first raised line high scale, thus further increase the service life of ruler.And further in the bottom of the top of the first raised line top, the second raised line, the first groove, the bottom of the second groove is provided with magnet, this makes it possible to make chi bar unit more stable when combining, being attracted each other by the magnetic force between magnet.Allow ruler in use, can not scatter easily between chi bar unit.And all chi bar unit being all set to transparent, this makes it possible to when drawing parallel lines, more convenient.

In figure: 1, chi bar unit; 11, the second chi bar; 12, the first chi bar; 2, scale; 3, the first raised line; 4, the first groove; 5, the second raised line; 6, the second groove; 7, magnet.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of durable combination ruler embodiment of the utility model is described further.
The durable combination ruler of one as shown in Figure 1 to Figure 3, comprise blade, blade comprises five chi bar unit 1 in the present embodiment, here each chi bar unit 1 comprises the first chi bar 12 and the second chi bar 11, here the first chi bar 12 and the second chi bar 11 are overlapping setting, and the first chi bar 12 and the second chi bar 11 are rectangular-shaped, further the front end face of the first chi bar 12 is provided with the first raised line 3, and the rear end face of the first chi bar 12 is provided with the first groove 4, the cross-sectional sizes of the first raised line 3 in the present embodiment, shape, the cross-sectional sizes of level height and the first groove 4, shape, level height is identical, be rectangle.The upper surface of the first raised line 3 is here provided with scale 2.The front end face of the second chi bar 11 is provided with the second raised line 5, the rear end face of the second chi bar 11 is here provided with the second groove 6, the cross-sectional sizes of the cross-sectional sizes of the second raised line 5 here, shape, level height and the second groove 6, shape, level height are identical, are also set to rectangle.In the present embodiment, the top of the first raised line 3 and the second raised line 5 is provided with magnet 7, and is equipped with magnet 7 in the bottom of the first groove 4 and the second groove 6.
Such setting, adjacent chi bar unit 1 just by cooperatively interacting between raised line and groove, thus can be combined.When the scale 2 on first chi bar unit 1 has worn and torn, or first raised line 3 surface fracture produce pit time, just can be dismantled, and the afterbody of last chi bar unit 1 can be engaged in, the first raised line 3 on chi bar unit 1 new so has just exposed, the scale 2 be arranged on the first raised line 3 is just intact again, is equivalent to change one new ruler.Being provided with several chi bar unit 1 is just equivalent to be provided with several new ruler.And after being pulled down by first chi bar unit 1, insert the afterbody of last chi bar unit 1, overall, do not affect the width of ruler, user still can be allowed to use very easily and survey and draw.
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.
