Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a detection device for internal defects in concrete. Background Technology

[0002] During the production and construction of concrete, defects such as voids and cracks may appear inside the concrete due to various reasons. These defects seriously affect the quality and performance of concrete and may even cause safety accidents. Therefore, it is necessary to detect internal defects in concrete.

[0003] When existing detection devices are used to detect areas with obstructions on the side, such as corners, it is necessary to manually release the fixed state of the detection device handle, rotate the handle to the side, and then re-fix it for detection. After the detection is completed, it must be restored to its original state. Currently, the fixing method is mostly to use threads, which makes the adjustment process cumbersome and inconvenient. In addition, when storing the detection device, it does not have the effect of protecting the detection head. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome and inconvenient adjustment methods and the lack of protection for the detection head when storing the device. This invention proposes a detection device for internal defects in concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detection device for internal defects in concrete includes a detection device, the detection device comprising a device body, a display screen disposed on the front of the device body, and a probe disposed on the back of the device body;

[0007] Two handles are provided for gripping the main body of the device. The two handles are located on both sides of the main body of the device, and the outer wall of the handles is fixedly covered with a rubber sleeve.

[0008] Two connecting plates are used to connect the handles to the main body of the device. One end of each connecting plate is fixedly set at the bottom of the two handles. Two cylinders are provided on both sides of the bottom of the main body of the device. A circular hole is opened at the end of the connecting plate away from the handle, and the circular hole is rotatably fitted onto the outer wall of the cylinder.

[0009] An adjustment assembly is used to adjust the connection state between the device body and the handle. The adjustment assembly is located on the top of the device body. The adjustment assembly includes two No. 1 cylinders and two adjustment plates. The two No. 1 cylinders are respectively located on both sides of the top of the device body. One end of each of the two adjustment plates is located at the top of the two handles. The other end of each of the two adjustment plates is provided with a polygonal hole, and the two polygonal holes are respectively fitted onto the outer wall of the two No. 1 cylinders. A polygonal ring is fixedly provided on the top of each No. 1 cylinder, and the two polygonal rings are respectively engaged with the two polygonal holes.

[0010] A fixing component is used to fix the adjustment plate, and the fixing component is set on the top of the device body.

[0011] In one possible design, the adjustment assembly further includes a connecting rod fixedly disposed at the bottom of the adjustment plate near the handle. The top of the handle has a slot and the connecting rod extends into the slot. A ring is fixedly sleeved on the outer wall of the connecting rod and on the side inside the slot. A compression spring is sleeved on the outer wall of the connecting rod, and the two ends of the compression spring are fixedly disposed on the inner wall of one side of the slot and one side of the ring, respectively.

[0012] In one possible design, a first limiting ring is fixedly installed at the top of the polygonal ring, and a second limiting ring is fixedly installed at the bottom of the second cylinder.

[0013] In one possible design, threaded grooves are provided on both sides of the top and both sides of the bottom of the main body of the device. Bolts are provided inside the threaded grooves, and two bolts are respectively threaded to the inner walls of cylinder No. 1 and cylinder No. 2.

[0014] In one possible design, the fixing assembly includes a horizontal plate and two insert rods. The horizontal plate is fixedly mounted on the top of the main body of the device. The same sliding cavity is opened on both sides of the horizontal plate. Two sliding plates are slidably arranged inside the sliding cavity. The two insert rods are respectively fixedly mounted at the ends of the two sliding plates that are far apart. The outer wall of the adjusting plate is provided with a slot. The two slots are respectively engaged with the two insert rods. The same second compression spring is fixedly arranged between the sides of the two sliding plates that are close to each other.

[0015] In one possible design, the fixing component further includes two triangular grooves respectively formed on the top of the two slide plates on adjacent sides, with triangular plates slidably disposed inside the triangular grooves, and the top of the two triangular plates being fixedly disposed on the same pressure plate, with the top of the pressure plate sliding through to the top of the horizontal plate.

[0016] In one possible design, the end of the insert near the slot is curved.

[0017] In this application, during actual use, the polygonal hole at one end of the adjusting plate is fitted onto the outer wall of the polygonal ring. At this time, the adjusting plate cannot rotate. When it is necessary to inspect the corner of the wall, press the adjusting plate, and the polygonal hole at one end of the adjusting plate will move to the outer wall of the first cylinder. At this time, the handle can be gripped and rotated to quickly adjust the handle. Afterward, the adjusting plate is reset by the first compression spring, so that the polygonal hole is fitted onto the outer wall of the polygonal ring again for fixation. This facilitates adjustment and is simple and practical.

[0018] When storing the detection device, press the adjustment plate to allow the handle to rotate, then move the handle to one side of the probe. When the slot on one side of the adjustment plate rotates to the side of the insertion rod, the second compression spring will reset and push the slide plate to move. The slide plate will then engage the insertion rod with the slot, allowing the detection device to be easily folded and stored. The two handles also provide some protection for the probe.

[0019] In this utility model, the device for detecting internal defects in concrete can be adjusted by pressing the adjustment plate when it is necessary to detect areas with obstructions such as corners. At this time, the polygonal hole at one end of the adjustment plate will move to the outer wall of the first cylinder, allowing the handle to be rotated for adjustment without the need to loosen the bolts. This is simple, convenient, and increases practicality.

[0020] In this utility model, the detection device for internal defects in concrete, through the fixing component, can achieve the following: when the main body of the device is folded and stored, it can be automatically locked by adjusting the component to rotate the handle to one side of the probe head, and the two handles can protect the probe head from movement.

[0021] In this utility model, when in use, the two handles are held for gripping and use. The angle of the handles can be adjusted by simply pressing the adjustment plate during use, thereby enabling detection at the corner of the wall, which is simple and convenient.

[0022] Furthermore, the fixing component allows the handle to be automatically fixed when rotated to one side of the probe, making it easy to fold and store while also providing some protection for the probe. Attached Figure Description
