[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 、 Figure 2 、 Figure 3As shown, the utility model provides a multifunctional measuring ruler, comprising a measuring main ruler 1, a scale line 2 fixedly painted on the left side of the measuring main ruler 1, a level slot 3 penetrating the rear side thereof is provided on the top of the measuring main ruler 1, a folding slot 4 penetrating the rear side thereof is provided on the bottom of the measuring main ruler 1, a turntable 31 is movably installed between the left and right sides of the inner wall of the level slot 3, a level 32 is fixedly installed on the bottom of the turntable 31, a rubber block 321 is fixedly installed on the left side of the level 32, a protractor 322 is fixedly installed on the front side of the rubber block 321, the level 32 is completely moved out of the inner side of the level slot 3 when in a horizontal state, two limit baffles 33 are fixedly installed on the front side of the inner wall of the level slot 3, the protractor 322 is located between the two limit baffles 33 when the level 32 is in a vertical state, and a connecting slot 34 penetrating to the inner cavity of the folding slot 4 is provided on the bottom of the inner wall of the level slot 3;

[0024] When it is necessary to monitor whether the building is vertical, just rotate and pull the spirit level 32 out of the spirit level slot 3, and press the rear end of the spirit level 32 against the wall, then observe the spirit level 32 and make fine adjustments until the spirit level 32 is horizontal. At this time, one end of the hanging movable measuring ruler 1 is away from the protractor 322 or a part of the protractor 322 is extended into the spirit level slot 3, and it can be concluded that there is a problem with the verticality of the measured building and marked. At the same time, when not in use, the spirit level 32 can be rotated and clamped back into the spirit level slot 3 until it stops against the rear end of the two limit baffles 33, and the rubber block 321 is used to improve the stability of the spirit level 32 in the spirit level slot 3. At the same time, the protractor 322 can also be placed exactly between the two limit baffles 33.

[0025] like Figure 4 、 Figure 5 As shown, a slide groove 11 is provided on the lower left and right sides of the measuring main ruler 1, which passes through the inner cavity of the folding card slot 4. A rotating shaft 41 is slidably installed on the inner side of the two slide grooves 11. A hanging block 43 is fixedly installed on the opposite surface of the two rotating shafts 41. A limit plate 42 is fixedly installed on the end of the two rotating shafts 41 away from the hanging block 43. The two limit plates 42 are respectively located on the left and right sides of the measuring main ruler 1. An extended folding ruler 44 is fixedly installed on the bottom of the hanging block 43. An extended folding ruler 44 is fixedly painted on the left side of the extended folding ruler 44. Scale line 441, after the extended folding ruler 44 is vertical, the extended scale line 441 and the scale line 2 can be docked for continuous measurement. The bottom of the extended folding ruler 44 is provided with a slot 442 that runs through the rear side thereof. The bottom front side of the main measuring scale 1 is provided with an embedded magnetic block 12, and the top front side of the extended folding ruler 44 is provided with an embedded magnetic block 2 443. When the embedded magnetic block 12 and the embedded magnetic block 2 443 are attracted to each other, the front side of the extended folding ruler 44 and the front side of the main measuring scale 1 are on the same vertical line;

[0026] When the length of the measuring main scale 1 is not enough for measurement, the card slot 442 can be pulled out of the folding card slot 4 and rotated. After keeping it vertical, it can be pulled backward. The rotating shaft 41 slides to the rear side in the slide groove 11, so that the extended folding scale 44 can be moved backward by using the hanging block 43. When the rotating shaft 41 moves to the rear side of the slide groove 11 and cannot move, the front side of the extended folding scale 44 is now in the same vertical line as the front side of the measuring main scale 1, and the adsorption of the embedded magnetic block 12 and the embedded magnetic block 2 443 is used to maintain the stability between the measuring main scale 1 and the extended folding scale 44 after unfolding, so that the extended measurement can be carried out.

[0027] like Figure 6 As shown, a hand-held rod slot 45 is provided on the front side of the inner wall of the folding slot 4, and a folding hand-held rod 451 is movably installed on the upper part between the left and right sides of the inner wall of the hand-held rod slot 45, and the folding hand-held rod 451 is clamped with the hand-held rod slot 45, and an arc-shaped rod 452 is fixedly installed on the upper rear side of the folding hand-held rod 451, and a conical rubber plug 453 is fixedly installed on the top of the arc-shaped rod 452, and the conical rubber plug 453 is located below the clamping slot 34, and the maximum diameter of the conical rubber plug 453 is wider than the diameter of the clamping slot 34, and an arc-shaped plastic strip 454 is fixedly installed on the lower rear side of the folding hand-held rod 451. After the extended folding ruler 44 is rotated counterclockwise and pushed forward, it is clamped with the folding slot 4, and after the clamping, the arc-shaped plastic strip 454 and the conical rubber plug 453 are both clamped with the slot 442;

[0028] When the surveyor cannot reach the position to be measured, he can use the curved plastic strip 454 to pull out the movable folding hand-held rod 451 in the hand-held rod slot 45 until the folding hand-held rod 451 maintains a horizontal state and extends out of the folding slot 4. At this time, the folding hand-held rod 451 can be fixed in the level instrument slot 3 by passing through the tapered rubber plug 453 at the top of the curved rod 452 through the snap-fitting slot 34 to keep it horizontal. The surveyor can use the folding hand-held rod 451 to lift the measuring ruler 1 and extend the folding ruler 44 to measure at a higher position. When not in use, the foldable handle 451 can be reversed, and the softness of the tapered rubber plug 453 can be used to pull it out of the engaging slot 34 with a little force and put it back into the folding engaging slot 4. At the same time, the extended folding ruler 44 can be slid forward and reversed to be re-engaged in the folding engaging slot 4. The engagement between the arc-shaped plastic strip 454, the tapered rubber plug 453 and the engaging slot 442 does not prevent the extended folding ruler 44 from being completely engaged in the folding engaging slot 4, but can also increase the stability of the extended folding ruler 44 after being engaged in the folding engaging slot 4, thereby making the entire measuring main ruler 1 convenient to carry.

[0029] The working principle of the multifunctional measuring ruler is described in detail below.

[0030] like Figure 1-6As shown, when it is necessary to monitor whether the building is vertical, it is only necessary to rotate and pull the spirit level 32 out of the spirit level slot 3, and press the rear end of the spirit level 32 against the wall, and then observe the spirit level 32 and make fine adjustments until the spirit level 32 is horizontal. At this time, one end of the hanging movable measuring ruler 1 is away from the protractor 322 or a part of the protractor 322 is extended into the spirit level slot 3, and it can be concluded that there is a problem with the verticality of the measured building and marked. At the same time, when not in use, the spirit level 32 can be rotated and clamped back into the spirit level slot 3 until it stops against the rear ends of the two limit baffles 33, and the rubber block 321 is used to raise the spirit level 3 2 is inserted into the level card slot 3 for stability, and the protractor 322 can also be placed exactly between the two limit baffles 33. When the length of the measuring main scale 1 is not enough, the card slot 442 can be pulled out from the folding card slot 4 and rotated. After keeping it vertical, it is pulled backward. The shaft 41 slides to the rearmost side in the slide slot 11, so that the extended folding scale 44 is moved backward by the hanging block 43. When the shaft 41 moves to the rearmost side of the slide slot 11 and cannot move, the front side of the extended folding scale 44 is now in the same vertical line with the front side of the measuring main scale 1, and the embedded magnetic block 12 and the embedded magnetic block 2 443 are attracted to each other. The stability between the measuring main ruler 1 and the extended folding ruler 44 after unfolding is maintained, and the extended measurement can be carried out. When the surveyor cannot reach the position to be measured, the curved plastic strip 454 can be used to pull out the movable folding hand-held rod 451 in the hand-held rod slot 45 until the folding hand-held rod 451 maintains a horizontal state and extends out of the folding slot 4. At this time, the folding hand-held rod 451 can be fixed by passing the conical rubber plug 453 at the top of the curved rod 452 through the snap-fitting slot 34 and snapped into the level meter slot 3 to keep it horizontal. The surveyor can use the folding hand-held rod 451 to lift the measuring main ruler 1 and the extended folding ruler 44. The ruler 44 can be used for measuring at higher heights. When not in use, the foldable handle 451 can be reversed. By utilizing the flexibility of the tapered rubber plug 453, it can be pulled out of the engaging slot 34 with a little force and turned back into the folding engaging slot 4. At the same time, the extended foldable ruler 44 can be slid forward and reversed to be re-engaged in the folding engaging slot 4. The engagement between the arc-shaped plastic strip 454, the tapered rubber plug 453 and the engaging slot 442 does not prevent the extended foldable ruler 44 from being fully engaged in the folding engaging slot 4, but can also increase the stability of the extended foldable ruler 44 after being engaged in the folding engaging slot 4, thereby making the measuring main ruler 1 convenient to carry as a whole.

[0031] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
