Specific Embodiments

[0027] The following will describe the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Referring to the attached Figure 1 - attached Figure 4 , the building engineering crack detection device provided by the present invention includes a positioning frame 1, and the positioning frame 1 is set as a cross structure;

[0029] A measuring mechanism, which is arranged at the rear side of the positioning frame 1;

[0030] The measuring mechanism includes a measuring plate 2, which is arranged at the rear side of the positioning frame 1. A connecting frame 3 is fixedly connected to the front side of the measuring plate 2. A transmission shaft 4 is fixedly connected to the front side of the connecting frame 3.

[0031] The measuring mechanism further includes two scale plates 5, which are respectively fixedly connected to the bottom and the bottom of the positioning frame 1.

[0032] In this embodiment, the user inserts two measuring rods 8 into the crack. The device is positioned on the wall surface by two positioning plates 18. The two moving rods 13 are rotated, so that the measuring mechanism measures the width of the crack.

[0033] Among them, in order to achieve the purpose of width measurement, the present device adopts the following technical solution: The measuring mechanism further includes a movable groove, which is arranged inside the measuring plate 2. A positioning rod 6 is fixedly embedded inside the movable groove. Two sliding blocks 7 are sleeved outside the positioning rod 6. Both of the two sliding blocks 7 slide relative to the positioning rod 6 and the movable groove. The measuring mechanism further includes two measuring rods 8. Both of the two measuring rods 8 are cylindrical structures. The two measuring rods 8 are respectively connected to the rear sides of the two sliding blocks 7. A spring 9 is embedded inside the movable groove. The spring 9 is sleeved outside the positioning rod 6. The spring 9 is fixedly connected between the two sliding blocks 7. A square rod 10 is arranged on the front side of the positioning frame 1. The square rod 10 is fixedly connected to the front end of the transmission shaft 4. A circular plate 11 is fixedly connected to the front end of the square rod 10. A moving block 12 is arranged outside the square rod 10. The moving block 12 is arranged at the rear side of the circular plate 11. The moving block 12 slides relative to the square rod 10.

[0034] The user rotates the two moving rods 13. The rotation of the moving rods 13 drives the square rod 10 to rotate. The rotation of the square rod 10 drives the transmission shaft 4 to rotate. The rotation of the transmission shaft 4 drives the connecting frame 3 to rotate. The rotation of the connecting frame 3 drives the measuring plate 2 to rotate. The rotation of the measuring plate 2 drives the two sliding blocks 7 and the measuring rods 8 to rotate. Since the two measuring rods 8 abut against both sides of the inner wall of the crack, the measuring rods 8 will move towards the middle under the extrusion of the inner wall of the crack. When the moving block 12 and the moving rod 13 rotate to the vertical position, the two measuring rods 8 are in a horizontal state. At this time, the distance between the two measuring rods 8 is the width data of the crack. The user can record the data by observing the scale indication position on the scale plate 5.

[0037] The use process of the present utility model is as follows: The user inserts the two measuring rods 8 into the crack, positions the device on the wall through the two positioning plates 18, turns the two moving rods 13, so that the measuring mechanism measures the width of the crack. The user turns the two moving rods 13, the rotation of the moving rods 13 drives the rotation of the square rod 10, the rotation of the square rod 10 drives the rotation of the transmission shaft 4, the rotation of the transmission shaft 4 drives the rotation of the connecting frame 3, the rotation of the connecting frame 3 drives the rotation of the measuring plate 2, the rotation of the measuring plate 2 drives the rotation of the two sliding blocks 7 and the measuring rods 8. Since the two measuring rods 8 are in contact with both sides of the inner wall of the crack, the measuring rods 8 will move towards the middle under the extrusion of the inner wall of the crack. When the moving block 12 and the moving rods 13 rotate to the vertical position, the two measuring rods 8 are in a horizontal state. At this time, the distance between the two measuring rods 8 is the width data of the crack. The user can record the data by observing the scale indication position on the scale plate 5. When the moving block 12 and the moving rods 13 rotate to the vertical position, the user presses the two moving rods 13, so that the two buckles 14 are inserted into the interior of the card sleeves 15 to fix the position of the measuring rod 8 and prevent the data from changing.
