[0027] A handheld ultrasonic flaw detector, as Figure 1 andFigure 2 As shown in the figure, it includes:

[0028] The flaw detector body 10, which has a housing structure with a cavity. An ultrasonic generator and an ultrasonic receiving module are installed in the cavity of the flaw detector body 10. A probe and a control panel are installed on the outside of the flaw detector body 10. A display screen is also installed on the outside of the flaw detector body 10. Specifically, the ultrasonic generator and the ultrasonic receiver are electrically connected to the control panel, and the probe and the display screen are electrically connected to the control panel. When the ultrasonic beam passes from the free probe into the metal interior and encounters defects and the bottom surface of the part, reflected waves are respectively generated, and pulse waveforms are formed on the display screen. The position and size of the defects are judged based on these pulse waveforms. This is the existing well-known technology and will not be elaborated here.

[0029] As Figure 2 、 Figure 3 and Figure 4 shown in the figure, a protection component is provided outside the flaw detector body 10 to wrap and protect the flaw detector body 10. The protection component includes a protective cover 20 and ribs 21. The protective cover 20 is sleeved outside the flaw detector body 10. Two groups of ribs 21 are provided on one side of the protective cover 20. Each group includes two ribs 21. The two ribs 21 in the same group are cross-distributed. The two groups of ribs 21 respectively form buffer zones on the sides of the display screen and the control panel. The wall surface of the protective cover 20 is provided with a limiting structure for clamping the ribs 21. The protective cover 20 forms an elastic square frame. A rectangular groove is opened on the inner wall surface of the protective cover 20. The rectangular groove is in interference fit with the flaw detector body 10. The flaw detector body 10 is snapped into the rectangular groove. The protective cover 20 forms a buffer area around the flaw detector body 10. The ribs 21 are integrally formed with the protective cover 20. One end on the same side of the two ribs 21 in the same group is fixedly connected to the protective cover 20. The other end of the rib 21 forms a free end. The free end of the rib 21 is clamped with the limiting structure. In this solution, both the protective cover 20 and the ribs 21 are made of rubber. The inside of the protective cover 20 is hollow and forms a buffer cavity. The buffer cavity is filled with gas. The square protective cover 20 wraps the flaw detector body 10 to form a protective barrier around it, preventing the flaw detector body 10 from being damaged by impact or falling vibration. By setting two groups of ribs 21, the two ribs 21 in the same group are cross-distributed, which can form an X-shaped buffer zone in the areas of the display screen and the control panel, playing a role in protecting the display screen and the control panel. The protection is more comprehensive, the overall quality is small, it is convenient to carry, and the load is reduced.

[0030] As Figure 3 shown in the figure, the protection component further includes an installation window 22. The installation window 22 is penetrated and opened at the top of the protective cover 20. The wire harness connected to the probe passes through the installation window 22 and extends to the outside of the protective cover 20. By setting the installation window 22, it is convenient for the probe to pass through, and thus it is convenient to install the flaw detector body 10 and the protective cover 20.

[0031] As Figure 3 shown, the protection component further includes a handle 23. The handle 23 is fixedly connected to the back surface of the protective cover 20. The handle 23 forms a U-shaped rod structure. A holding cavity is formed between the handle 23 and the back surface of the protective cover 20. The palm can pass through the holding cavity to hold the handle 23. By setting the handle 23, when holding and using the flaw detector body 10, the palm can pass through the groove of the handle 23, that is, the holding cavity. The handle 23 forms a limit on the side of the bent palm, reducing the probability of dropping when holding the flaw detector body 10 and facilitating holding and use.

[0032] As Figure 4 and Figure 5 shown, the limiting structure includes a first protrusion 30 fixedly connected to the protective cover 20; a second protrusion 31 fixedly connected to the first protrusion 30. An anti-detachment hole 32 is formed on the wall surface of the rib 21. The second protrusion 31 and the anti-detachment hole 32 can pass through the anti-detachment hole 32. The second protrusion 31 and the first protrusion 30 are integrally formed. The first protrusion 30 forms a cylindrical structure. The second protrusion 31 is hemispherical. The anti-detachment hole 32 is a circular hole. The diameter of the anti-detachment hole 32 is smaller than the diameter of the second protrusion 31. As a supplementary description of the above solution, by setting the second protrusion 31, during storage, the anti-detachment hole 32 of the rib 21 can be aligned with the second protrusion 31 and squeezed. The second protrusion 31 passes through the anti-detachment hole 32 to limit the rib 21 between the second protrusion 31 and the first protrusion 30, realizing the clamping limit of the rib 21, and then keeping the two ribs 21 distributed in a cross shape. When in use, the rib 21 can be wound around the back surface of the flaw detector body 10 and clamped with the second protrusion 31. The rib 21 is on the back surface of the protective cover 20, and thus will not block the display screen and the control panel, having the characteristic of flexibly adjusting the position of the rib 21, being able to flexibly switch between the protection and storage functions, and being more convenient to use.

[0033] Working principle of the utility model: The flaw detector body 10 is squeezed into the rectangular groove of the protective cover 20, and the protective cover 20 made of rubber material shrinks to wrap the flaw detector body 10 for installation. When storing, the anti-detachment hole 32 of the rib 21 can be aligned with the second protrusion 31 and squeezed. The second protrusion 31 passes through the anti-detachment hole 32 to limit the rib 21 between the second protrusion 31 and the first protrusion 30, realizing the clamping limit of the rib 21, and then keeping the two ribs 21 cross-distributed. When in use, the rib 21 can be wound around the back of the flaw detector body 10 and clamped with the second protrusion 31. The rib 21 is on the back of the protective cover 20, so it will not block the display screen and the control panel. When holding the flaw detector body 10 for use, the palm can pass through the groove of the handle 23, that is, the holding cavity. The handle 23 forms a limit on one side of the bent palm, reducing the probability of the flaw detector body 10 falling off when held. Both the protective cover 20 and the rib 21 are made of rubber material. The inside of the protective cover 20 is hollow and forms a buffer cavity. The buffer cavity is filled with gas. The protective cover 20 in a zigzag shape wraps the flaw detector body 10 to form a protective barrier around the protective cover 20, preventing the flaw detector body 10 from being damaged by impact or dropping vibration. Two groups of ribs 21 are provided, and the two ribs 21 in the same group are cross-distributed, which can form an X-shaped buffer zone in the display screen and control panel area.
