Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , an embodiment provided by the present utility model:

[0026] A crack detection device for construction engineering, comprising:

[0027] The main body includes a body 1, a display screen 11 and a button 12 are arranged on the surface of the body 1, a connecting line 13 is fixedly connected to the surface of the body 1, an ultrasonic probe 14 is fixedly connected to the surface of the connecting line 13, a special scale 15 is arranged on the outside of the body 1, the body 1 and the ultrasonic probe 14 are connected through the connecting line 13, lines can be drawn on the surface to be tested through the special scale 15, and lines can be drawn along the straight edges of the grooves on the special scale 15 at the same time, so that the distance between each straight edge line segment is the same, and a coupling agent is applied to the surface of the object to be tested, and two groups of ultrasonic probes 14 are placed on the surface coated with the coupling agent, and different positions are changed for detection, and the relevant data after detection can be displayed on the display screen 11 by controlling the button 12;

[0028] The shading mechanism includes a cover plate 2, which is movably connected to the surface of the body 1, and a mounting plate 21 and a first mounting block 23 are fixedly connected to the surface of the body 1. A slide groove 22 is provided on the surface of the mounting plate 21, and a rotating groove 24 is provided inside the first mounting block 23. A rotating rod 25 is fixedly connected to the surface of the cover plate 2, and a movable plate 26 is movably connected to the surface of the cover plate 2. A short screw 27 and a rotating block 28 are fixedly connected to the surface of the movable plate 26, and a nut 29 is installed on the surface of the short screw 27. Under the action of the cover plate 2, a shading effect is achieved for the detection device when it is used outdoors to prevent the light from being too strong to make it difficult to see the data on the display screen 11.

[0029] Furthermore, the size of the cover plate 2 is larger than that of the display screen 11, and two groups of mounting plates 21 and first mounting blocks 23 are provided. The two groups of mounting plates 21 and first mounting blocks 23 are installed on both sides of the display screen 11, and the rotating rod 25 is rotatably connected to the surface of the rotating groove 24. Under the connection between the rotating groove 24 and the rotating rod 25, the cover plate 2 can be rotated around the rotating rod 25.

[0030] Furthermore, one end of the movable plate 26 is fixedly connected to the surface of the rotating block 28, and the other end of the movable plate 26 is fixedly connected to the surface of the short screw 27. The short screw 27 is slidably connected to the surface of the slide groove 22. A through hole is opened on the surface of the cover plate 2. Under the action of the movable plate 26, the support effect of the cover plate 2 is achieved, so that the cover plate 2 forms a certain angle with the outer surface of the body 1.

[0031] Furthermore, one side of the rotating block 28 is fixedly connected to the surface of the movable plate 26 through a through hole, the other side of the rotating block 28 is attached to the inner surface of the cover plate 2, the nut 29 is threadedly connected to the surface of the short screw rod 27. Under the action of the rotating block 28, during the rotation of the cover plate 2, the movable plate 26 can rotate on the surface of the cover plate 2 with the rotating block 28 as the center, thereby driving the short screw rod 27 to slide on the sliding groove 22. At the same time, under the connection of the nut 29 and the short screw rod 27, the rotation angle of the cover plate 2 can be limited, so that the device can maintain the adjusted angle during use.

[0032] Furthermore, a clamping mechanism is arranged on the surface of the special scale 15. The clamping mechanism includes a limiting rod 3. The limiting rod 3 is fixedly connected to the surface of the machine body 1. A second mounting block 31 is fixedly connected to the surface of the machine body 1. A rotating shaft 32 is fixedly connected to the surface of the second mounting block 31. A clamping plate 33 is movably connected to the surface of the rotating shaft 32. A through groove 34 is opened inside the clamping plate 33. A torsion spring 35 is installed on the surface of the through groove 34. The special scale 15 can be clamped on its surface through the two groups of limiting rods 3, thereby realizing the placement of the special scale 15 on the machine body 1, which is convenient for taking and using.

[0033] Furthermore, the cross section of the limiting rod 3 is arranged in an "L" shape and there are two groups. The two groups of limiting rods 3 are arranged on both sides of the special scale 15. There are two groups of second mounting blocks 31. The two groups of second mounting blocks 31 are arranged on both sides of the limiting rod 3. The number of each group of second mounting blocks 31 is two. Both ends of the rotating shaft 32 are fixedly connected to the surface of the second mounting block 31. Under the connection action of the second mounting block 31 and the rotating shaft 32, the clamping plate 33 rotates with the rotating shaft 32 as the center.

[0034] Furthermore, the cross section of the clamping plate 33 is in a "C" shape. One end of the clamping plate 33 is rotatably connected to the surface of the rotating shaft 32 through the through groove 34. The other end of the clamping plate 33 is clamped to the surface of the special scale 15. The torsion spring 35 is sleeved on the surface of the rotating shaft 32. The torsion spring 35 can provide a force, so that the clamping plate 33 is clamped at the groove on the surface of the special scale 15, thereby limiting the installed special scale 15.

[0035] Working principle: When using this crack detection device, first rotate the cover plate 2 with the rotating rod 25 as the center. During the rotation, the movable plate 26 rotates with the rotating block 28 as the center. And before the rotation, the nut 29 is rotated under the action of the thread, so that the nut 29 no longer abuts against the mounting plate 21. After the movable plate 26 rotates, it drives the short screw rod 27 to slide on the sliding groove 22. When it rotates to the required light-shielding angle, then rotate the two nuts 29 on both sides to make them abut against the mounting plate 21, thereby limiting the position of the cover plate 2 to realize the light-shielding treatment of the display screen 11.

[0036] After using the special scale 15, closely attach the special scale 15 to the outer surface of the machine body 1 and snap it into the gap between the two groups of limit rods 3. At this time, rotate the clamping plates 33 on both sides so that the clamping plates 33 rotate around the rotating shaft 32. The torsion spring 35 twists to generate a force on the clamping plates 33. After the special scale 15 is snapped in, release the clamping plates 33. Under the action of the torsion spring 35, one side of the clamping plate 33 is snapped and connected to the groove on the surface of the special scale 15 to complete the installation of the special scale 15.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
