DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1

[0021] Reference Figure 1-4 A verticality measuring device comprises a plumb block 1 and a plumb line 2, the plumb line 2 is fixed on the plumb block 1, a fixed cover 4 is fixed on the plumb line 2, a transparent protective cover 5 and a vertical plate 6 are fixed on the fixed cover 4, and the vertical plate 6 and the fixed cover 4 are vertically arranged, the fixed cover 4 and the transparent protective cover 5 are connected, and the fixed cover 4 and the transparent protective cover 5 protect the plumb block 1 and the plumb line 2, and block the wind for the plumb block 1 and the plumb line 2, and the transparent protective cover 5 will not block the sight of the staff to see the plumb block 1 and the plumb line 2;

[0022] A fixing frame 8 is fixed inside the fixed cover 4, and a first cylinder 7 is fixed on the fixing frame 8. The plumb line 2 is arranged to pass through the first cylinder 7. A wire wheel 11 is fixed inside the fixed cover 4, and the wire wheel 11 is in contact with the plumb line 2. The arrangement of the wire wheel 11 and the first cylinder 7 allows the transparent protective cover 5 and the vertical plate 6 to be parallel to each other when the vertical plate 6 is in a vertical state, so that the plumb line 2 with the plumb block 1 is in the middle position of the transparent protective cover 5. A protractor 10 and two rulers 9 are fixed on one of the inner side walls of the transparent protective cover 5 from top to bottom, and the top end of the protractor 10 is flush with the bottom end of the first cylinder 7. Through the transparent protective cover 5, the protractor 10 and the two rulers 9 can be directly seen, and then the position of the plumb line 2 in the transparent protective cover 5 can be checked.

[0023] When in use, the staff holds the vertical board 6 and presses the vertical board 6 against the structural column. At this time, the staff observes the plumb line 2 stretched vertically by the plumb block 1, and uses the protractor 10 and two rulers 9 to reflect whether the plumb line 2 and the vertical board 6 are parallel. When the plumb line 2 is at the same value on the two rulers 9, it means that the structural column pressed against by the vertical board 6 is vertical to the horizontal line, otherwise it is the opposite. The protractor 10 can measure the offset angle, and the fixed cover 4 and the transparent protective cover 5 are used to protect the plumb block 1 and the plumb line 2 in all directions, and sufficient space is left for the use of the plumb block 1 and the plumb line 2, which will not affect the use of the plumb block 1 and the plumb line 2. At the same time, the plumb block 1 and the plumb line 2 can be blocked from the wind, so that when used in windy weather, the wind will not blow the plumb block 1 to shake, ensuring that the plumb block 1 and the plumb line 2 will not be restricted by windy weather when used, and the accuracy of the plumb block 1 and the plumb line 2 when used can be ensured.

[0024] Example 2

[0025] In Example 1, since the plumb block 1 is suspended in the transparent protective cover 5 and the plumb block 1 is naturally drooping, when not in use, when the verticality measuring device is carried, the plumb block 1 will frequently hit the transparent protective cover 5, and the transparent protective cover 5 is easily blurred or damaged by the collision, which will affect the line of sight or affect the windproof effect of the plumb block 1 and the plumb line 2. Figure 1 , 2 , 3 and 5, as another preferred embodiment of the utility model, the difference from embodiment 1 is that a wire-retracting mechanism is fixed between the plumb line 2 and the fixed cover 4, the wire-retracting mechanism includes a rotating shaft 3, the rotating shaft 3 penetrates and is rotatably arranged on the fixed cover 4, the plumb line 2 is fixed on the rotating shaft 3, a disc 12 is fixed on one end of the rotating shaft 3 outside the fixed cover 4, the rotating shaft 3 is rotated to allow the plumb line 2 to wrap around the rotating shaft 3 until the plumb block 1 is against the first cylinder 7, so that when the verticality measuring device is carried, the plumb block 1 will not hit the transparent protective cover 5, thereby ensuring the safety of the transparent protective cover 5.

[0026] The disc 12 and the fixed cover 4 are provided with a locking mechanism, which is used to fix the rotating shaft 3 so that the plumb line 2 wound on the rotating shaft 3 will not loosen when it is not needed. The locking mechanism includes a plurality of insertion holes 13 and a threaded rod 14. The plurality of insertion holes 13 are equidistantly arranged on the circumferential side of the disc 12. The threaded rod 14 is inserted into one of the insertion holes 13. A limit assembly is provided on the threaded rod 14. The limit assembly is fixed to the fixed cover 4. The limit assembly includes a fixed rod 16. The fixed rod 16 is fixed to the fixed cover 4. A second cylinder 15 is fixed to the fixed rod 16. The second cylinder 15 is threadedly sleeved on On the threaded rod 14, by twisting the threaded rod 14, the length of the threaded rod 14 on both sides of the second cylinder 15 can be adjusted. When in use, the plumb line 2 is wound around the rotating shaft 3 until the plumb block 1 is against the first cylinder 7, keeping the disc 12 stationary, twisting the threaded rod 14, and inserting the threaded rod 14 into one of the insertion holes 13 on the disc 12. Since the second cylinder 15 that limits the threaded rod 14 is fixed to the fixed cover 4 through the fixing rod 16, the cooperation between the threaded rod 14 and the insertion hole 13 can lock the disc 12, so that the disc 12 will not rotate, thereby keeping the position of the plumb block 1 unchanged.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
