Description

Technical Field

[0001] This application relates to the field of detection and maintenance equipment technology, and in particular to flaw detectors and their light shields. Background Technology

[0002] An ultrasonic flaw detector is a non-destructive testing instrument that can quickly, safely, and accurately detect, locate, and diagnose internal defects in an object.

[0003] When flaw detector personnel use ultrasonic flaw detectors, the strong light reflection from the main unit screen or water droplets falling on the screen during rain often makes it difficult to see the wave output on the screen, thus affecting the judgment of the flaw detector personnel and causing misjudgments or missed judgments. Utility Model Content

[0004] Therefore, it is necessary to provide a flaw detector and its light shield to address the problem that strong light reflection on the main screen of an ultrasonic flaw detector or water droplets falling on the main screen during rain can obscure the wave output on the screen, affecting the judgment of flaw detection personnel and causing misjudgments or missed judgments.

[0005] A light shield, the light shield comprising:

[0006] The bracket includes a connector and two snap-fit ​​members, the two snap-fit ​​members being respectively connected to both ends of the connector along a first direction, and the main unit of the flaw detector being snapped between the two snap-fit ​​members; and

[0007] The cover includes a cover plate and two connecting plates. When the cover plate covers the host, both ends of the cover plate along a first direction are respectively connected to the two connecting plates, and the connecting plates are perpendicular to the cover plate. With the first direction as the axis of rotation, one end of the two connecting plates along a second direction is rotatably connected to the opposite side of the two snap-fit ​​pieces, so that the cover plate can cover or be removed from the screen of the host. The first direction, the second direction, and the third direction are perpendicular to each other, and the third direction is the thickness direction of the host.

[0008] In actual use, the aforementioned light shield connects the two snap-fit ​​pieces to the two ends of the connecting piece along the first direction. Therefore, the main unit of the flaw detector can be snapped between the two snap-fit ​​pieces. When the main unit is snapped between the two snap-fit ​​pieces, the display panel and operating plate of the main unit face the cover plate. When the cover plate covers the main unit, the two connecting plates are located on both sides of the main unit along the first direction, which can more fully protect the main unit. The connecting plates are used to rotate and connect with the snap-fit ​​pieces, thereby moving the cover plate closer to or away from the main unit, thus simultaneously protecting the main unit and providing light and rain protection. At a small angle, the cover plate and the two connecting plates can provide light or rain protection to three sides of the main unit, making it easier for the operator to view the main unit display panel.

[0009] In one embodiment, the light shield further includes two first rotating shafts, which are respectively located on both sides of the host along a first direction. The first rotating shafts pass through the corresponding connecting plate and the snap-fit ​​member, so that the connecting plate and the snap-fit ​​member are rotatably connected.

[0010] In one embodiment, the light shield further includes two frame assemblies, which are located on both sides of the host along a first direction, and the frame assemblies are rotatably connected to the bracket about an axis in the first direction.

[0011] In one embodiment, the skeleton assembly further includes a first skeleton and connecting lines;

[0012] One end of each of the two first frames is rotatably connected to the side of the two connecting plates that are close to each other, and the other end of the first frame is provided with a through hole;

[0013] The connecting wire passes through the through hole, with one end of the connecting wire connected to the corresponding connecting plate and the other end connected to the corresponding snap-fit ​​component.

[0014] In one embodiment, the skeleton component further includes a second skeleton;

[0015] One end of the second frame is rotatably connected to each of the two snap-fit ​​pieces, and the other end is connected to the end of the corresponding connecting line that is away from the connecting plate.

[0016] In one embodiment, the skeleton assembly further includes a second rotating shaft, the second skeleton having a strip-shaped hole, the strip-shaped hole being arc-shaped, the second rotating shaft passing through the strip-shaped hole and the snap-fit ​​member, the second rotating shaft being movable within the strip-shaped hole.

[0017] In one embodiment, the skeleton assembly further includes a third pivot shaft passing through the first skeleton and the connecting plate to allow the first skeleton to rotate about the connecting plate.

[0018] In one embodiment, the bracket further includes a first extension, a second extension, and a protrusion connected in sequence. One end of the first extension is connected to the connector and extends along a second direction. The first extension and the cover plate are located on the same side of the connector and extend in the same direction. The second extension extends along the third direction toward the cover plate. The protrusion extends along the second direction toward the connector. Along the second direction, the main unit is snapped between the connector, the first extension, the second extension, and the protrusion.

[0019] In one embodiment, the light shield further includes a rotating assembly, which includes a fixing member, a rotating member, and a rotating head. One end of the rotating member is rotatably connected to the fixing member, and the other end is connected to the rotating head. The end of the rotating head opposite to the rotating member is connected to the bracket.

[0020] Another embodiment of this application also provides a flaw detector, the flaw detector comprising: a detection device, a main unit, and the aforementioned light shield;

[0021] The detection device is connected to the host computer via a signal.

[0022] The host is attached to the bracket.

[0023] In actual use, the aforementioned flaw detector uses a detection device to perform flaw detection and transmit data to the host computer. The host computer controls the flaw detector and performs operations such as inputting flaw detection commands or changing parameters. Since the two locking pieces are connected to the two ends of the connecting piece along the first direction, the host computer of the flaw detector can be locked between the two locking pieces. When the host computer is locked between the two locking pieces, the display panel and operation panel of the host computer face the cover plate. When the cover plate covers the host computer, the two connecting plates are located on both sides of the host computer along the first direction, thus providing more comprehensive protection for the host computer. The connecting plates are rotatably connected to the locking pieces. The operator can grasp the end of the cover plate away from the connecting piece and rotate the cover plate relative to the bracket around the first direction axis, thereby moving the cover plate closer to or away from the host computer. This simultaneously protects the host computer and provides light and rain protection. At small angles, the cover plate and the two connecting plates can provide light or rain protection to three sides of the host computer, making it easier for the operator to view the host computer's display panel.

[0043] See Figure 3 , Figure 3 A schematic diagram of the structure of a light shield 10 in one embodiment of this application is shown. The light shield 10 provided in one embodiment of this application includes: a bracket 100 and a cover 200.

[0044] See Figure 1 and Figure 2In the aforementioned light shield 10, the bracket 100 includes a connector 110 and two snap-fit ​​pieces 120. The two snap-fit ​​pieces 120 are respectively connected to both ends of the connector 110 along the first direction OX. The main unit 20 of the flaw detector is snapped between the two snap-fit ​​pieces 120. The cover body 200 includes a cover plate 210 and two connecting plates 220. When the cover plate 210 covers the main unit 20, both ends of the cover plate 210 along the first direction OX are respectively connected to the two connecting plates 220, and the connecting plates 220 are perpendicular to the cover plate 210. With the first direction OX as the axis of rotation, one end of the two connecting plates 220 along the second direction OY is rotatably connected to the opposite side of the two snap-fit ​​pieces 120, so that the cover plate 210 can cover or be removed from the screen of the main unit 20. The first direction OX, the second direction OY, and the third direction OZ are perpendicular to each other, and the third direction OZ is the thickness direction of the main unit 20.

[0045] In actual use, the aforementioned sunshade 10, such as Figure 1 and Figure 2 As shown, since the two connectors 120 are respectively connected to the two ends of the connector 110 along the first direction OX, the main unit 20 of the flaw detector can be connected between the two connectors 120. When the main unit 20 is connected between the two connectors 120, the display panel 21 and operation panel 22 of the main unit 20 face the cover plate 210. When the cover plate 210 covers the main unit 20, the two connecting plates 220 are respectively located on both sides of the main unit 20 along the first direction OX, thereby providing more adequate protection for the main unit 20. The connecting plates 220 are used... The cover plate 210 is rotatably connected to the connector 120. The operator can grasp the end of the cover plate 210 away from the connector 110 and drive the cover plate 210 to rotate relative to the bracket 100 around the first direction OX. This causes the cover plate 210 to move closer to or away from the host 20, thus simultaneously protecting the host 20 and shielding it from light and rain. At a small angle, the cover plate 210 and the two connector plates 220 can shield three sides of the host 20 from light or rain, making it easier for the operator to see the display panel 21 of the host 20 more clearly.

[0046] In one embodiment, the light shield 10 further includes two first rotating shafts 300, which are located on both sides of the host 20 along the first direction OX. The first rotating shafts 300 pass through the corresponding connecting plate 220 and the snap-fit ​​member 120 so that the connecting plate 220 and the snap-fit ​​member 120 are rotatably connected, thereby enabling the connecting plate 220 to rotate relative to the snap-fit ​​member 120 around the axis of the first direction OX, so that the cover plate 210 can cover or open the host 20.

[0047] Specifically, the first rotating shaft 300 is a bolt, which causes the connecting plate 220 to rotate relative to the snap-fit ​​120. The bolt can be tightened and abut against the main unit 20 so that the angle between the connecting plate 220 and the snap-fit ​​120 is fixed, thus fixing the angle between the sunshade 10 and the main unit 20, so as to facilitate fixed-angle sunshade and rain protection.

[0048] See Figure 1 In one embodiment, the light shield 10 further includes two skeleton components 400, which are located on both sides of the host 20 along the first direction OX. The skeleton components 400 are rotatably connected to the bracket 100 around the axis of the first direction OX, so that the skeleton components 400, the light shield 10, and the host 20 can be opened in a fan shape, making the opening more stable.

[0049] See Figure 1 In one embodiment, the skeleton assembly 400 further includes a first skeleton 410 and a connecting line 420. One end of each of the two first skeletons 410 is rotatably connected to the side of the two connecting plates 220 that are close to each other, and the other end of the first skeleton 410 is provided with a through hole 411. The connecting line 420 passes through the through hole 411, with one end of the connecting line 420 connected to the corresponding connecting plate 220 and the other end connected to the corresponding snap-fit ​​member 120. Thus, the connecting plate 220, the first skeleton 410, and the snap-fit ​​member 120 are connected through the connecting line 420, which ensures the limit rotation angle between the first skeleton 410 and the connecting plate 220 and the snap-fit ​​member 120, as well as the limit rotation angle between the connecting plate 220 and the snap-fit ​​member 120, preventing excessive rotation and ensuring more convenient light blocking.

[0050] See Figure 1 In one embodiment, the skeleton assembly 400 further includes a second skeleton 430. One end of the second skeleton 430 is rotatably connected to two snap-fit ​​pieces 120, and the other end is connected to the end of the corresponding connecting line 420 facing away from the connecting plate 220, thereby extending the snap-fit ​​pieces 120 along the second direction OY through the second skeleton 430, so that when the cover 200 is opened, the cover 200, the first skeleton 410, the second skeleton 430, and the main unit 20 form a fan shape. The limit rotation angles among the cover 200, the first skeleton 410, and the second skeleton 430 are fixed to ensure rotational stability.

[0051] See Figure 1In one embodiment, the skeleton assembly 400 further includes a second rotating shaft 440. The second skeleton 430 has a strip hole 431, which is arc-shaped. The second rotating shaft 440 passes through the strip hole 431 and the snap-fit ​​member 120. The second rotating shaft 440 can move within the strip hole 431, thereby making the rotation of the second skeleton 430 relative to the snap-fit ​​member 120 more flexible, improving the limit rotation angle of the second skeleton 430, and limiting the rotation through the arc-shaped strip hole 431.

[0052] Specifically, the second rotating shaft 440 is a rotating pin.

[0053] See Figure 1 In one embodiment, the skeleton assembly 400 further includes a third pivot 450, which passes through the first skeleton 410 and the connecting plate 220 to allow the first skeleton 410 to rotate about the connecting plate 220.

[0054] Specifically, the third rotating shaft 450 is a bolt, which causes the connecting plate 220 to rotate relative to the first frame 410. The bolt can be tightened to fix the first frame 410 relative to the connecting plate 220, so that the angle between the first frame 410 and the connecting plate 220 remains stable.

[0055] See Figure 1 , Figure 2 as well as Figure 3 In one embodiment, the bracket 100 further includes a first extension 130, a second extension 140, and a protrusion 150 connected in sequence. One end of the first extension 130 is connected to the connector 110 and extends along the second direction OY. The first extension 130 and the cover plate 210 are located on the same side of the connector 110 and extend in the same direction. The second extension 140 extends along the third direction OZ towards the cover plate 210. The protrusion 150 extends along the second direction OY towards the connector 110. Along the second direction OY, the main unit 20 is snapped between the connector 110, the first extension 130, the second extension 140, and the protrusion 150. In this embodiment, the length of the second extension 140 is greater than or equal to the thickness of the main unit 20, and the first extension 130, the second extension 140 and the protrusion 150 are all elastic, so that the main unit 20 can be snapped between the two snap-fit ​​members 120, the first extension 130, the second extension 140 and the protrusion 150.

[0056] Preferably, the bracket 100 further includes a plurality of abutment protrusions, which pass through the first extension 130, the second extension 140 and the third extension, and abut against the main unit 20.

[0057] Specifically, the first extension 130, the second extension 140, and the protrusion 150 are all elastic plates that can deform when the main unit 20 is snapped between the first extension 130, the second extension 140, and the protrusion 150. Then, the shape is restored and the main unit 20 is fixed along the first direction OX and the second direction OY by elastic force.

[0058] Preferably, the snap-fit ​​member 120 has a support portion 121 and two protruding plates 122. The two protruding plates 122 are respectively connected to the two ends of the support portion 121 along the third direction OZ. The protruding plates 122 of the two snap-fit ​​members 120 extend towards each other along the first direction OX. A snap-fit ​​groove is formed between the support portion 121 and the two protruding plates 122. The main unit 20 is partially snapped into the snap-fit ​​groove, thereby making the main unit 20 snapped between the support portion 121, the protruding plates 122, the first extension portion 130, the second extension portion 140 and the protruding portion 150.

[0059] Specifically, the connector 110 is rotatably connected to the corresponding support 121, and the second frame 430 is rotatably connected to the support 121.

[0060] Preferably, the light shield 10 further includes a fastener 600, which passes through the connector 110 and abuts against the side of the main unit 20 away from the cover plate 210. By tightening the fastener 600, the main unit 20 is snapped between the fastener 600 and the protrusion 150, thereby making the main unit 20 stably fixed between the support 121, the protrusion 122, the first extension 130, the second extension 140, and the protrusion 150. If the main unit 20 needs to be removed, simply loosen the fastener 600 and remove the main unit 20 by overcoming the elastic force of the first extension 130, the second extension 140, and the protrusion 150.

[0061] See Figure 1 In one embodiment, the light shield 10 further includes a rotating assembly 500, which includes a fixing member 510, a rotating member 520, and a rotating head 530. One end of the rotating member 520 is rotatably connected to the fixing member 510, and the other end is connected to the rotating head 530. The end of the rotating head 530 facing away from the rotating member 520 is connected to the bracket 100, thereby fixing the light shield 10 and the main unit 20 to the position to be fixed by the fixing member 510. The rotating connection between the fixing member 510 and the rotating member 520, and the rotating connection between the rotating member 520 and the rotating head 530, enables the light shield 10 and the main unit 20 to rotate at multiple angles relative to the fixed position.

[0062] Preferably, the rotating head 530 and the rotating component 520, and the rotating component 520 and the fixed component 510 are all universal rotating assemblies 500. For details, refer to the prior art, such as universal heads and other devices, which will not be described in detail here.

[0063] Preferably, the rotating assembly 500 further includes a locking member 540. The rotating member 520 includes a first rotating part 521 and a second rotating part 522. The first rotating part 521 is rotatably connected to the rotating head 530, and the second rotating part 522 is rotatably connected to the fixing member 510. A connecting groove is provided at one end of the first rotating part 521 and the second rotating part 522 that are close to each other. The two connecting grooves form a locking hole. The locking member 540 passes through the locking hole and can abut against the outer wall of the rotating member 520, thereby fixing the angle of the first rotating part 521 and the second rotating part 522.

[0064] Preferably, the cover plate 210 has a protruding strip 211 protruding toward the host 20. When the cover plate 210 covers the host 20, the protruding strip 211 abuts against the host 20 and extends along the second direction OY, thereby further fixing the host 20.

[0065] Another embodiment of this application provides a flaw detector (not shown), which includes: a detection device (not shown), a main unit 20, and a light shield 10. The detection device is signal-connected to the main unit 20. The main unit 20 is snapped onto the bracket 100.

[0066] In actual use, the aforementioned flaw detector uses a detection device to perform flaw detection and transmit data to the host 20. The host 20 controls the flaw detector and performs operations such as inputting flaw detection commands or changing parameters. Since the two latches 120 are respectively connected to the two ends of the connector 110 along the first direction OX, the host 20 of the flaw detector can be latched between the two latches 120. When the host 20 is latched between the two latches 120, the display panel 21 and operation panel 22 of the host 20 face the cover plate 210. When the cover plate 210 covers the host 20, the two connecting plates 220 are located on both sides of the host 20 along the first direction OX, thus providing more comprehensive protection for the host 20. The connecting plates 220 are used to connect with… The snap-fit ​​connector 120 is rotatably connected. The operator can grasp the end of the cover plate 210 away from the connector 110 and drive the cover plate 210 to rotate relative to the bracket 100 around the first direction OX. This causes the cover plate 210 to move closer to or away from the host 20, thus simultaneously protecting the host 20 and providing light and rain protection. At a small angle, the cover plate 210 and the two connecting plates 220 can provide light or rain protection to three sides of the host 20, making it easier for the operator to view the display panel 21 of the host 20 more clearly.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
