Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detectors, in particular to a light-proof protective ultrasonic flaw detector. Background Art

[0002] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece quickly, conveniently, non-destructively and accurately. It can be used in laboratories as well as on-site projects.

[0003] During outdoor on-site testing, the display screen of the ultrasonic flaw detector is difficult to see clearly due to the influence of outdoor lighting.

[0004] In this regard, the patent with the announcement number CN211785338U discloses "An ultrasonic flaw detector anti-strong light exposure device", such as Figure 1 As shown, the device includes an ultrasonic flaw detector body 1, a display screen 2 is provided on the front side of the ultrasonic flaw detector body 1, a U-shaped sleeve plate 3 is provided around the upper edge of the ultrasonic flaw detector body 1, a first U-shaped telescopic light baffle 4 is slidably sleeved in the U-shaped sleeve plate 3, a second U-shaped telescopic light baffle 5 is slidably sleeved in the first U-shaped telescopic light baffle 4, and a pull plate 6 is provided on the front side of the second U-shaped telescopic light baffle 5.

[0005] By pulling the pull plate 6, the second U-shaped telescopic light blocking plate 5 is pulled out through the first U-shaped telescopic light blocking plate 4, and the first U-shaped telescopic light blocking plate 4 is pulled out through the U-shaped sleeve plate 3, so that the display screen 2 can be shielded in the left and right directions and the top direction to achieve the effect of preventing light.

[0006] Although the above device can block light, in the above device, the display screen is located on the front side of the ultrasonic flaw detector body. When there is no need to block light, the surface of the display screen is exposed to the outside without any shielding, and there is a risk of the display screen being damaged (smashed or scratched) by foreign objects.

[0007] Therefore, how to protect the display screen of the ultrasonic flaw detector from light and also protect the display screen when light protection is not needed is a technical problem that needs to be solved at present. Utility Model Content

[0008] In view of the above-mentioned deficiencies in the prior art, the utility model provides a light-proof protective ultrasonic flaw detector. The utility model can not only prevent light, but also protect the display screen of the ultrasonic flaw detector when light protection is not required.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A light-proof protective ultrasonic flaw detector comprises an ultrasonic flaw detector body, a display screen is arranged on the front side of the ultrasonic flaw detector body, and a shading structure is arranged on the ultrasonic flaw detector body, wherein a column is arranged on the front side of the ultrasonic flaw detector body, the column is arranged at the upper corner of the display screen, the outer side of the column is rotatably connected with a ring body, the outer side of the ring body is provided with a cross bar, the end of the cross bar away from the ring body is provided with a vertical bar, the upper end of the vertical bar is provided with a sliding pin, and the shading structure comprises a baffle, the surface of the baffle is provided with a guide rail, and the guide rail is provided with a first sliding hole and a second sliding hole connected vertically, when the sliding pin slides to the end of the first sliding hole away from the second sliding hole, the baffle covers the surface of the display screen, and when the sliding pin slides to the end of the second sliding hole away from the first sliding hole, the baffle is perpendicular to the surface of the display screen.

[0011] Furthermore, a first damping structure is provided between the column and the ring body.

[0012] Furthermore, a second damping structure is provided on the hole wall of the first sliding hole and the second sliding hole.

[0013] Furthermore, a support body is provided on the front side of the ultrasonic flaw detector body, and when the baffle covers the surface of the display screen, the upper surface of the support body abuts against the lower surface of the baffle.

[0014] Furthermore, an adsorption structure is provided on the upper surface of the support body, and the adsorption structure is used to adsorb the baffle.

[0015] Furthermore, the adsorption structure adopts magnet.

[0016] Furthermore, a groove is provided on the upper surface of the support body, and the magnet is provided in the groove.

[0017] The utility model has the beneficial effects:

[0018] 1. When the sliding pin is located at the end of the first sliding hole away from the second sliding hole, the baffle covers the surface of the display screen. At this time, the surface of the display screen is fully shielded by the baffle, and the baffle protects the display screen, preventing the display screen from being damaged or scratched by foreign objects, thereby improving the protection effect of the display screen.

[0019] When the sliding pin is located at an end of the second sliding hole away from the first sliding hole, the baffle plate is perpendicular to the surface of the display screen. At this time, the baffle plate can be used to block light, so that users can observe the data displayed on the display screen.

[0020] In summary, the utility model can not only prevent light, but also protect the display screen of the ultrasonic flaw detector when light protection is not needed.

[0021] 2. When the baffle is perpendicular to the surface of the display screen, the light-blocking position of the baffle can be flexibly adjusted by rotating the ring body, thereby improving the flexibility of use. For example, when the baffle is rotated to the left side of the display screen, the light can be blocked from the left side of the display screen; when the baffle is rotated to the upper side of the display screen, the light can be blocked from the upper side of the display screen.

[0022] 3. The setting of the first damping structure can increase the rotational resistance between the column and the ring body, stabilize the position of the ring body after rotation, and improve the stability of the current position of the ring body.

[0023] 4. The second damping structure can improve the friction resistance between the first sliding hole and the second sliding hole and the sliding pin, so as to improve the stability of the baffle when it is perpendicular to the display screen surface or covers the display screen surface.

[0024] 5. By setting a support body, when the baffle covers the surface of the display screen, the support body can abut against the lower surface of the baffle together with the column, so that the baffle is supported by the column and the support body, allowing the baffle to maintain better balance and allowing the baffle to block the surface of the display screen more stably.

[0025] 6. The setting of the adsorption structure can further stabilize the state of the baffle covering the surface of the display screen, prevent the baffle from being easily opened, and further improve the effect of protecting the display screen.

[0026] 7. Using magnets as adsorption mechanisms can facilitate material collection. In addition, by embedding the magnets in the slot, it is possible to prevent the magnets from protruding above the upper surface of the support, which is beneficial for reducing the thickness of the entire structure and facilitating storage.

[0046] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] Example:

[0048] like Figure 2-Figure 13 As shown, a light-proof protective ultrasonic flaw detector comprises an ultrasonic flaw detector body 1, a display screen 2 is provided on the front side of the ultrasonic flaw detector body 1, and a light-shielding structure is provided on the ultrasonic flaw detector body 1.

[0049] like Figure 3 As shown, a column 7 is provided on the front side of the ultrasonic flaw detector body 1, and the column 7 is located at the upper left corner of the display screen 2. The column 7 can be welded and fixed on the ultrasonic flaw detector body 1.

[0050] like Figure 3 As shown, a ring body 8 is sleeved on the outer side of the column 7, and the ring body 8 is rotatably matched with the column 7.

[0051] In order to stabilize the relative rotation state between the ring body 8 and the column 7 , a first damping structure is provided between the column 7 and the ring body 8 .

[0052] like Figure 3 As shown, the first damping structure includes a resistance increasing convex portion 71 and a resistance increasing concave portion 81. The outer side surface of the column 7 is provided with a resistance increasing convex portion 71, and the resistance increasing convex portion 71 and the column 7 are an integral structure, and the inner side surface of the ring body 8 is provided with a plurality of resistance increasing concave portions 81, and the resistance increasing convex portion 71 cooperates with the resistance increasing concave portions 81.

[0053] Turn the ring body 8 forcefully to squeeze the resistance increasing protrusion 71 out of the old resistance increasing recess 81. As the ring body 8 rotates, the resistance increasing protrusion 71 can enter the new resistance increasing recess 81. After the rotation of the ring body 8 is completed, the current state of the ring body 8 can be stabilized because of the cooperation between the resistance increasing protrusion 71 and the resistance increasing recess 81.

[0054] like Figure 3 As shown, in order to prevent the ring body 8 from separating from the column 7, a limiting protrusion 72 is provided on the outer side of the upper end of the column 7, and the limiting protrusion 72 can be welded and fixed on the outer side of the upper end of the column 7.

[0055] like Figure 3 As shown, a horizontal bar 82 is provided on the outer side of the ring body 8, and the horizontal bar 82 is parallel to the surface of the display screen 2. A vertical bar 83 is provided at one end of the horizontal bar 82 away from the ring body 8, and the vertical bar 83 is perpendicular to the surface of the display screen 2. A sliding pin 831 is provided at the upper end of the vertical bar 83. The ring body 8, the horizontal bar 82, the vertical bar 83, and the sliding pin 831 can be an integrated structure, or can be welded and fixed in sequence.

[0056] like Figure 5 , Figure 7 , Fig. 9 As shown, the shading structure includes a baffle 9. Figure 6 , Figure 8 , Fig.10As shown, a guide rail 91 is welded and fixed on the surface of the baffle 9 , and a first sliding hole 911 and a second sliding hole 912 which are vertically connected are provided on the guide rail 91 .

[0057] like Fig.10 As shown, when the sliding pin 831 is located at the end of the first sliding hole 911 away from the second sliding hole 912, the baffle 9 covers the surface of the display screen 2. At this time, the surface of the display screen 2 is fully shielded by the baffle 9, and the baffle 9 protects the display screen 2, preventing the display screen 2 from being damaged or scratched by foreign objects, thereby improving the protection effect of the display screen 2.

[0058] like Fig.13 As shown, when the sliding pin 831 is located at one end of the second sliding hole 912 away from the first sliding hole 911, the baffle 9 is perpendicular to the surface of the display screen 2. At this time, the baffle 9 can be used to block light so that users can observe the data displayed on the display screen 2.

[0059] In summary, this embodiment can not only prevent light exposure, but also protect the display screen 2 of the ultrasonic flaw detector when light exposure is not required.

[0060] In addition, when the baffle 9 is perpendicular to the surface of the display screen 2, the light-blocking position of the baffle 9 can be flexibly adjusted by rotating the ring body 8, thereby improving the flexibility of use. For example, when the baffle 9 is rotated to the left side of the display screen 2, the light can be blocked from the left side of the display screen 2; when the baffle 9 is rotated to the upper side of the display screen 2, the light can be blocked from the upper side of the display screen 2.

[0061] When the baffle 9 is adjusted from the state of covering the surface of the display screen 2 to the state of being perpendicular to the surface of the display screen 2: first, see Figure 10 to Figure 11 The state changes, with the sliding pin 831 as the rotation center, the baffle 9 is rotated counterclockwise; then, see Figure 10 to Figure 11 Then Fig.12 The state changes, pushing the baffle 9, allowing the sliding pin 831 to slide from the first sliding hole 911 to the second sliding hole 912. When the sliding pin 831 slides to the end of the second sliding hole 912 away from the first sliding hole 911, the baffle 9 abuts against the surface of the cross bar 82, and the guide rail 91 abuts against the surface of the ultrasonic flaw detector body 1, so that the baffle 9 is stable in a state perpendicular to the surface of the display screen 2.

[0062] When the baffle 9 is adjusted from a state perpendicular to the surface of the display screen 2 to a state covering the surface of the display screen 2: first, see Figure 13 to Figure 12 Then Fig.11 The state changes, pull the baffle 9 in the direction away from the ultrasonic flaw detector body 1, and let the sliding pin 831 slide from the second sliding hole 912 to the first sliding hole 911; then, see Figure 11 to Figure 10When the sliding pin 831 slides to the end of the first sliding hole 911 away from the second sliding hole 912, the baffle plate 9 is rotated clockwise so that the baffle plate 9 covers the surface of the display screen 2.

[0063] In order to further stabilize the sliding state of the sliding pin 831 in the first sliding hole 911 and the second sliding hole 912 , a second damping structure is provided on the hole walls of the first sliding hole 911 and the second sliding hole 912 .

[0064] In this embodiment, the second damping structure can adopt a resistance-increasing convex strip (not shown in the figure), and a plurality of resistance-increasing convex strips are provided on the hole walls of the first sliding hole 911 and the second sliding hole 912, and the guide rail 91 and the resistance-increasing convex strip are an integral structure. The resistance-increasing convex strip can increase the friction resistance between the first sliding hole 911 and the second sliding hole 912 and the sliding pin 831, so as to improve the stability of the baffle 9 when it is perpendicular to the surface of the display screen 2 or covers the surface of the display screen 2.

[0065] Further, such as Figure 4 As shown, a support body 10 is provided on the front side of the ultrasonic flaw detector body 1, and the support body 10 can be welded and fixed to the ultrasonic flaw detector body 1. When the baffle 9 covers the surface of the display screen 2, the support body 10 can abut against the lower surface of the baffle 9 together with the column 7, so that the baffle 9 is supported by the column 7 and the support body 10, so that the baffle 9 can maintain a better balance, so that the baffle 9 can block the surface of the display screen 2 more stably.

[0066] Furthermore, Figure 4 As shown, the upper surface of the support body 10 is provided with an adsorption structure, which is used to adsorb the baffle 9. The setting of the adsorption structure can further stabilize the state of the baffle 9 covering the surface of the display screen 2, prevent the baffle 9 from being easily opened, and further improve the effect of protecting the display screen 2.

[0067] Specifically, the adsorption structure can be a magnet 101. When the magnet 101 is used as the adsorption structure, Figure 4 As shown, a slot 102 is provided on the upper surface of the support body 10, and the magnet 101 is embedded in the slot 102, and the baffle 9 is made of a metal material that can be adsorbed by the magnet 101, such as an iron plate. The magnet 101 is used as an adsorption mechanism, which can facilitate material collection. In addition, by embedding the magnet 101 in the slot 102, the magnet 101 can be prevented from protruding above the upper surface of the support body 10, which is conducive to reducing the thickness of the entire structure and facilitating storage.

[0068] In addition, a suction cup (not shown in the figure) can also be used as an adsorption structure. In this case, the baffle 9 can be pressed toward the position of the suction cup to squeeze out the air between the suction cup and the baffle 9, so that the suction cup can adsorb the baffle 9. Using a suction cup as an adsorption mechanism is also convenient for material collection.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
