Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-5, a kind of project cost drawing scale ruler, including main scale 1, the top of the positive right side of face of main scale 1 and
Bottom is fixedly installed with mounting blocks 2, and the quantity of mounting blocks 2 is two, and the equal movable sleeve in the inside of two mounting blocks 2 is connected to circular shaft
3, the back side of circular shaft 3 is fixedly installed with rotary ruler 4, and when rotary ruler 4 is in the case where rotating 180 degree, rotary ruler 4 is positive
Scale text with the positive scale text of main scale 1 be corresponding, to will not influence the measurement work of engineer, 4 institute of rotary ruler
The angular range being able to rotate is zero to 180 degree, and the positive bottom of rotary ruler 4 is equipped with scale text, the quantity of rotary ruler 4
It is two, the top and bottom of two rotary rulers 4 are fixedly installed with the first fitting block 5 above and below main scale 1 respectively
With the second fitting block 6, the first fitting block 5 and the second fitting block 6 are that magnet is made, and the first fitting block 5 and second is bonded
The magnetic pole of block 6 between the first fitting block 5 and the second fitting block 6 on the contrary, so that will fit closely, to prevent two
It is rotated between rotary ruler 4, engineer has been convenient for measure, the top and bottom of two rotary rulers 4 top with main scale 1 respectively
It is flexibly connected with bottom, the left side of main scale 1 is fixedly installed with lateral mass 8, and lateral mass 8 is that magnet is made, and it is iron for attracting block 7
At, therefore two top and bottom for attracting block 7 that can be adsorbed on lateral mass 8 respectively, two the fixed of rotary ruler 4 are made to be formed
With, it is therefore prevented that rotary ruler 4 arbitrarily rotates, and the left side of two rotary rulers 4 offers side port 11, the positive cross-sectional area of side port 11
Equal to the positive cross-sectional area of shrinkage-rule 9, and the positive cross-sectional area of side port 11 is greater than the attraction positive cross-sectional area of block 7, from
And realizing shrinkage-rule 9 by side port 11 and can reach the outside of rotary ruler 4, therefore increase the measurement model of the scale bar
It encloses, is fixedly installed with strip 10 at the top of 4 inner cavity of rotary ruler, strip 10 is that magnet is made, and the magnetic pole of the first fitting block 5
With the magnetic pole of strip 10 on the contrary, so that first to be bonded be not in repulsive force between block 5 and strip 10, rotary ruler 4 it is interior
Portion's movable sleeve is connected to the shrinkage-rule 9 positioned at 10 lower section of strip, the scale text at 4 top of scale text and rotary ruler at 9 top of shrinkage-rule
It is corresponding, and shrinkage-rule 9 is fabricated from iron, since shrinkage-rule 9 is made of iron, the top and bottom of shrinkage-rule 9 respectively with
Strip 10 mutually attracts with the first fitting block 5, to play a fixed function to shrinkage-rule 9, it is therefore prevented that shrinkage-rule 9 is arbitrarily stretched
Contracting, and engineer can according to need the length to select pulling shrinkage-rule 9, and for measuring, one end of shrinkage-rule 9 is solid
Surely it is connected with the attraction block 7 positioned at 4 right hand external of rotary ruler, attracting the quantity of block 7 is two, the size phase of two attraction blocks 7
Deng two attraction blocks 7 are flexibly connected about 8 central symmetry of lateral mass, the top of shrinkage-rule 9 with the bottom of strip 10, shrinkage-rule 9
The bottom that bottom is bonded 5 inner cavity of block with first is flexibly connected.
When work, engineer can according to need the size of measurement drawing, so that rotary ruler 4 is rotated 180 degree,
The second fitting block 6 is bonded the attraction of 5 phase of block and is bonded with first at this time, and the positive scale text of rotary ruler 4 and main scale 1 are positive
Scale text is corresponding, then can use, if need to measure some large-sized drawings, work at this time
Cheng Shi, which can be pulled, attracts block 7, so that shrinkage-rule 9 is stretched out by side port 11 from the inside of rotary ruler 4 and the first fitting block 5, and
And the positive scale text of shrinkage-rule 9 is corresponding with the positive scale text of rotary ruler 4, so that the measurement range of the scale bar increases
Add, can measure use later.
