Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detectors, and more specifically, to a light-shielding device for an ultrasonic flaw detector. Background Art

[0002] An ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument that can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose various defects inside workpieces. It can be used both in laboratories and on engineering sites, and is widely used in industries such as boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical industry, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing, steel structures, railway transportation, nuclear power, and universities.

[0003] When the display screen of an ultrasonic flaw detector faces strong light, the surface of the screen will reflect the strong light, and the liquid crystal display carried by the backlight of the screen itself will be mixed and interfered by the reflected strong light, thus affecting the flaw detection personnel's observation of the information on the display screen and bringing defects.

[0004] After retrieval, a Chinese patent with the publication number CN219456058U discloses a light-shielding device for an ultrasonic flaw detector. This structure uses the cooperation of an ultrasonic flaw detector body, a light-shielding plate, hinge parts, and a positioning component. When the ultrasonic flaw detector body is in use, the light-shielding plate can rotate relative to the hinge parts, so that the light-shielding plate rotates and opens, and the light-shielding plate is in a stable state to block the strong light, so as to facilitate the observation of the information on the ultrasonic flaw detector body.

[0005] However, in actual use, this structure can only perform light-shielding operations on the upper part of the ultrasonic flaw detector. When the strong light is on the side of the ultrasonic flaw detector, the light-shielding effect is poor and the light-shielding range is limited. In view of this, the present utility model provides a light-shielding device for an ultrasonic flaw detector. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a light-shielding device for an ultrasonic flaw detector to solve the problems raised in the above background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: A light-shielding device for an ultrasonic flaw detector, including an upper light-shielding plate installed on the ultrasonic flaw detector body. Two groups of support seats are provided at the top of the ultrasonic flaw detector body. The number of each group of support seats is set to two, and an adjusting block is provided between the two support seats. Both adjusting blocks are fixedly connected to the bottom of the upper light-shielding plate. Shaft rods are provided at both ends of the adjusting block, and the adjusting block is rotatably connected between the two support seats through the shaft rods. Locking nuts are threadedly installed on the outer part of the shaft rods.

[0008] It can be seen that in the above structure, the shading angle of the upper light shielding plate can be adjusted by rotating the adjustment block inside the support seat through the shaft rod, so that the upper light shielding plate can perform shading operation on the upper position of the display screen, and the upper light shielding plate can also be adjusted to the surface of the display screen to block and protect the display screen. The locking nut rotates on the external thread of the shaft rod, which can have a certain locking effect on the upper light shielding plate, avoiding the upper light shielding plate from rotating without reason, and making the upper light shielding plate have a certain tightness when rotating and adjusting.

[0009] In order to achieve the side shading effect on both sides of the ultrasonic flaw detector and improve the shading effect, preferably, the side shading structure includes side shading plates, an active cavity is opened inside the upper shading plate, and the side shading plates are slidably installed in the active cavity, and two inner walls of the active cavity are opened with sliding grooves, and a slider is arranged inside the sliding groove, an extension plate is arranged at one end of the slider, and the slider is fixedly installed on the outer wall of one end of the extension plate, and the slider matches the sliding groove structure, the slider is inside the sliding groove and slidably connected with the sliding groove, a damping sleeve is arranged on the surface of the extension plate, and a damping shaft is arranged on the two outer walls of the side shading plates, one end of the side shading plate is located between the two extension plates, and one end of the damping shaft is damped and rotated inside the damping sleeve, and a pull plate is arranged at one end of the side shading plate, and the pull plate is detachably mounted on one end of the upper shading plate by screws, and a pull groove is opened on the surface of the pull plate.

[0010] Technical effects and advantages of the utility model:

[0011] 1. By setting a side shading structure, the side shading plate is pulled out from the movable cavity opened by the upper shading plate, so that the slider slides and guides inside the slide groove, and the extension plate is also extended from the inside of the movable cavity. The side shading plate rotates between the two extension plates using the damping shaft inside the damping sleeve to adjust the shading angle of the side shading plate, thereby being able to perform shading treatment on the side of the display screen of the ultrasonic flaw detector, and the side shading plate can be stored conveniently to reduce the occupied area;

[0012] 2. The upper shading plate can be used to perform shading treatment on the upper part of the display screen of the ultrasonic flaw detector body. The upper shading plate can be rotated between the corresponding two support seats through the adjustment block fixed at the bottom through the shaft rod, and the shading angle of the upper shading plate can be adjusted. At the same time, it is convenient to adjust the upper shading plate to protect the surface of the display screen. After the angle of the upper shading plate is adjusted, the locking nut rotates on the external thread of the shaft rod, which can have a certain locking effect on the upper shading plate, preventing the upper shading plate from rotating without reason, so that the upper shading plate has a certain tightness during the rotation adjustment;

[0013] In summary, by using the above structure in combination, it can achieve a comprehensive light-shielding effect on the display screen of the ultrasonic flaw detector body, with good light-shielding effect, and it can be flexibly adjusted with a wide operating range.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As shown in the attached Figures 1-5 The ultrasonic flaw detector light-shielding device shown includes an upper light-shielding plate 2 installed on the ultrasonic flaw detector body 1. Two groups of support seats 3 are provided at the top of the ultrasonic flaw detector body 1. The number of each group of support seats 3 is set to two, and an adjusting block 4 is provided between the two support seats 3. Both adjusting blocks 4 are fixedly connected to the bottom of the upper light-shielding plate 2. Shaft rods 13 are provided at both ends of the adjusting block 4. The adjusting block 4 is rotatably connected between the two support seats 3 through the shaft rods 13, and locking nuts 14 are threadedly installed on the outer part of the shaft rods 13.

[0022] Specifically, in this structure, the upper light shielding plate 2 can be used to perform upper shading treatment on the display screen of the ultrasonic flaw detector body 1. The upper light shielding plate 2 can be rotated between the corresponding two support seats 3 through the shaft rod 13 through the adjustment block 4 fixed at the bottom, and the shading angle of the upper light shielding plate 2 can be adjusted. At the same time, it is convenient to adjust the upper light shielding plate 2 to protect the surface of the display screen. After the angle of the upper light shielding plate 2 is adjusted, the locking nut 14 is rotated on the external thread of the shaft rod 13 to fix the adjusted upper light shielding plate 2 to ensure that the upper light shielding plate 2 can perform shading operations on the upper part of the display screen.

[0023] In a specific embodiment, as shown in the attached Figure 4 , 5 As shown, the side shading structure includes a side shading plate 5, an active cavity 6 is opened inside the upper shading plate 2, the side shading plate 5 is slidably installed inside the active cavity 6, and the two inner walls of the active cavity 6 are opened with a slide groove 7, a slider 8 is arranged inside the slide groove 7, an extension plate 9 is arranged at one end of the slider 8, the slider 8 is fixedly installed on the outer wall of one end of the extension plate 9, the slider 8 matches the structure of the slide groove 7, the slider 8 is inside the slide groove 7 and is slidably connected with the slide groove 7, a damping sleeve 10 is arranged on the surface of the extension plate 9, and a damping shaft 11 is arranged on the two outer walls of the side shading plate 5, one end of the side shading plate 5 is located between the two extension plates 9, and one end of the damping shaft 11 is damped and rotated inside the damping sleeve 10, and a pull plate 12 is arranged at one end of the side shading plate 5, and the pull plate 12 is detachably installed on one end of the upper shading plate 2 by screws, and a pull groove 15 is opened on the surface of the pull plate 12.

[0024] Specifically, in this structure, after the upper shading plate 2 shades the upper part of the display screen of the ultrasonic flaw detector body 1, the operator can release the screws at the pull plate 12 according to the shading situation, and pull the pull plate 12 outward through the pull groove 15, and the pull plate 12 drives the side shading plate 5 to slide from the inside of the movable cavity 6 opened by the upper shading plate 2, and drives the slider 8 to slide inside the slide groove 7 through the extension plate 9;

[0025] When the slider 8 slides to the end inside the slide groove 7, at this time, the extension plate 9 can extend from the inside of the active cavity 6, and the operator adjusts the angle of the side shading plate 5 according to the shading angle, so that the damping shaft 11 rotates in the damping sleeve 10. There is a certain damping tightness between the damping shaft 11 and the damping sleeve 10, and the operator needs to rotate the side shading plate 5 to achieve adjustment. Under normal circumstances, the side shading plate 5 will not rotate without reason, and the adjusted side shading plate 5 can play the role of side shading, thereby improving the shading effect.

[0026] Working principle of this utility model:

[0027] During the specific use of the above structure, when the ultrasonic flaw detector body 1 is performing metal flaw detection, the operator needs to read data through the display screen on the ultrasonic flaw detector. When the display screen is affected by strong light and affects data reading;

[0028] First, the operator adjusts the upper light-shielding plate 2 so that the adjusting block 4 fixed at the bottom of the upper light-shielding plate 2 rotates between the corresponding two support seats 3 through the shaft rod 13, and the light-shielding angle of the upper light-shielding plate 2 can be adjusted. At the same time, it is convenient to adjust the upper light-shielding plate 2 to achieve the effect of protecting the surface of the display screen. After the upper light-shielding plate 2 is adjusted in angle, the locking nut 14 rotates on the external thread of the shaft rod 13 to fix the adjusted upper light-shielding plate 2 to ensure that the upper light-shielding plate 2 can perform light-shielding operation on the upper part of the display screen;

[0029] If the upper light-shielding plate 2 is difficult to achieve a comprehensive light-shielding effect on the display screen, or when the strong light is not in the position of the upper light-shielding plate 2, the operator, according to the situation, first removes the screw at the pull plate 12 and pulls the pull plate 12 outward through the pull groove 15. The pull plate 12 drives the side light-shielding plate 5 to slide outward from the inside of the movable cavity 6 opened in the upper light-shielding plate 2, and the extension plate 9 drives the slider 8 to slide inside the chute 7;

[0030] When the slider 8 slides to the end inside the chute 7, at this time, the extension plate 9 can extend out from the inside of the movable cavity 6. The operator adjusts the angle of the side light-shielding plate 5 according to the light-shielding angle, so that the damping shaft 11 rotates dampingly inside the damping sleeve 10, and the light-shielding angle of the side light-shielding plate 5 can be adjusted. Furthermore, the adjusted side light-shielding plate 5 can achieve the effect of side light-shielding and improve the light-shielding effect;

[0031] The side light-shielding plate 5 can be stored in the movable cavity 6 opened in the upper light-shielding plate 2 in the same way, reducing the occupied area and not affecting the normal data reading of the ultrasonic flaw detector body 1.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
