The moving distance is affected by the position of the first threaded ring, so that the device can arbitrarily adjust the detection position during use, so that the device can easily adjust the detection position and area.
[0032] Example
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the crack lengths are different under different depths, and the existing equipment is difficult to adjust the equipment according to the depth of the crack to be detected during use, resulting in large limitations in its use. The overall idea is as follows: a crack detection device with adjustable detection area, including a detection box 11, both side walls of the detection box 11 are provided with inner grooves 12, and adjustment legs 13 are slidably installed inside the two inner grooves 12, and the upper end of the detection box 11 is provided with a strip groove 14, and the inner wall of the strip groove 14 is symmetrically provided with a first slide groove 15;
[0034] A fixing strip 16 is fixedly installed in the inner wall of the strip groove 14, a screw 17 is fixedly installed on the upper end of the fixing strip 16, a first threaded ring 18 is threadedly sleeved on the screw 17, and receiving grooves 19 are opened on both side walls of the detection box 11;
[0035] An adjustment mechanism is provided inside the strip groove 14;
[0036] The adjustment mechanism includes an adjustment block 21, which is slidably arranged in the strip groove 14. First sliders 22 are fixedly installed on the side walls of both sides of the adjustment block 21. The two first sliders 22 are respectively slidably arranged in the two first slide grooves 15. A U-shaped bar 23 is fixedly installed on the upper end of the adjustment block 21. An inner column 24 is fixedly installed through the adjustment block 21. Second slide grooves 25 are symmetrically opened on the side walls of the inner column 24. Slide columns 26 are symmetrically slidably installed inside the inner column 24. A contact plate 27 is fixedly installed on the opposite ends of the two slide columns 26. When in use, the device can be prevented at the detection point first. At this time, the two adjustment legs 13 can be adjusted according to the width of the crack. It is drawn out from the two inner grooves 12 and used to place the device. After placement, the two second threaded rings 31 can be rotated on the inner column 24. The rotation of the two second threaded rings 31 will drive the two groups of second sliders 28 to slide toward both ends inside the two groups of second slide grooves 25. At this time, the two groups of second sliders 28 will drive the two slide posts 26 to slide toward both ends inside the inner column 24. At this time, the two slide posts 26 will drive the two contact plates 27 to move toward both ends. When the two contact plates 27 are aligned with the crack, the length of the crack can be obtained by adding the length of the detection box 11 and the length of the two contact plates 27 extending out, so that the device is more convenient for crack detection when in use;
[0037] Second slide blocks 28 are symmetrically fixedly installed on the side walls of the two slide posts 26. The two groups of second slide blocks 28 are respectively slidably arranged in the two groups of second slide grooves 25. Limiting grooves 29 are provided on the two groups of second slide blocks 28. Second threaded rings 31 are symmetrically threadedly sleeved on the inner column 24. The two second threaded rings 31 are respectively rotated and arranged in the two groups of limiting grooves 29. When it is necessary to detect deeper, the first threaded ring 18 can be rotated on the screw rod 17, and it will move downward under the rotation of the first threaded ring 18. At this time, the U-shaped bar 23 and the adjusting block 21 will slide downward accordingly under the action of gravity. At this time, the adjusting block 21 will drive the first slide block 22 to slide downward in the first slide groove 15. At this time, the inner column 24, the slide post 26 and the contact plate 27 will also move accordingly. The moving distance is affected by the position of the first threaded ring 18, so that the device can also adjust the detection position arbitrarily when in use, so that the device is convenient for adjusting the detection position and area.
[0038] In view of the problems existing in the prior art, the utility model provides a crack detection device with an adjustable detection area. Through the design of the first slide groove 15, the first threaded ring 18, the adjustment block 21, the first slider 22, the U-shaped bar 23, the inner column 24, the slide column 26 and the contact plate 27, the first slide groove 15 will move downward under the rotation of the first threaded ring 18. At this time, the U-shaped bar 23 and the adjustment block 21 will slide downward accordingly under the action of gravity. At this time, the adjustment block 21 will drive the first slider 22 to slide downward inside the first slide groove 15. At this time, the inner column 24, the slide column 26 and the contact plate 27 will also move accordingly. The moving distance is affected by the position of the first threaded ring 18, so that the device can arbitrarily adjust the detection position when in use, so that the device can be conveniently adjusted to the detection position and area.
[0039] Working principle:
[0040] The first step is to place the device at the detection point when in use. At this time, the two adjustment legs 13 can be pulled out from the two inner grooves 12 according to the width of the crack to place the device. After placement, the two second threaded rings 31 can be rotated on the inner column 24. The rotation of the two second threaded rings 31 will drive the two groups of second sliders 28 to slide toward both ends inside the two groups of second slide grooves 25. At this time, the two groups of second sliders 28 will drive the two slide posts 26 to slide toward both ends inside the inner column 24. At this time, the two slide posts 26 will drive the two contact plates 27 to move toward both ends. When the two contact plates 27 are aligned with the crack, the length of the crack can be obtained by adding the length of the detection box 11 and the length of the two contact plates 27 extending out, so that the device is more convenient for crack detection when in use.
[0041] In the second step, when it is necessary to detect deeper, the first threaded ring 18 can be rotated on the screw 17, and the device will move downward under the rotation of the first threaded ring 18. At this time, the U-shaped bar 23 and the adjustment block 21 will slide downward under the action of gravity. At this time, the adjustment block 21 will drive the first slider 22 to slide downward in the first slide groove 15. At this time, the inner column 24, the slide column 26 and the contact plate 27 will also move accordingly. The moving distance is affected by the position of the first threaded ring 18, so that the device can arbitrarily adjust the detection position when in use, making it easy to adjust the detection position and area of the device.
[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
