Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detector technology, and in particular to a light-shielding device for an ultrasonic flaw detector. Background Technology

[0002] An ultrasonic flaw detector is a non-destructive testing device that utilizes the physical properties of ultrasonic waves, such as reflection and refraction, as they propagate through a medium, to detect, locate, quantify, and qualitatively analyze internal defects (such as cracks, pores, and inclusions) in metallic and non-metallic materials. With its advantages of high detection accuracy, convenient operation, and non-destructive nature, it is widely used in many fields such as machinery manufacturing, petrochemicals, aerospace, rail transportation, and construction engineering, and is a key testing tool for ensuring the quality and safety of industrial products and the stable operation of equipment.

[0003] In the actual use of ultrasonic flaw detectors, their display area is used to present key information such as waveforms and data generated during the detection process. However, in industrial environments, there are often various light sources that interfere with the display area, such as indoor lighting and outdoor natural light (sunlight). When these lights shine on the display area of ​​the flaw detector, they are very easy to reflect, causing problems such as reflection and glare on the display screen. This makes it difficult for operators to clearly identify the waveforms and data on the screen, which not only increases the risk of misjudgment but may also prolong the detection time and reduce the efficiency of the detection work. The commonly used technical solution in the industry is to install a flip-up cover at the edge of the display area of ​​the ultrasonic flaw detector. This cover is usually made of opaque or low-transmittance material. When light blocking is needed, the operator can flip the cover to cover the display area to block external light. The size of the cover is fixed. However, in actual use, due to differences in models and usage scenarios, gaps may form between the flipped cover and the detector body and the edge of the display area that are difficult to eliminate. External light can still shine onto the display screen through these gaps, resulting in poor light blocking effect. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a light-shielding device for an ultrasonic flaw detector, so as to solve the technical problem that the current ultrasonic flaw detector's flip-up cover plate, due to its fixed size, is prone to forming gaps with the edge of the machine body and display area after flipping in different models of equipment and different usage scenarios, resulting in poor light-shielding effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An ultrasonic flaw detector light shielding device includes an ultrasonic flaw detector body, which is provided with a button area, a speaker area, and a display area for display. The ultrasonic flaw detector body is also provided with a deflectable light shielding mechanism. The light-shielding mechanism includes an active slide rail and a driven slide rail that are detachably mounted on the ultrasonic flaw detector body. A synchronous slide is movably connected between the active slide rail and the driven slide rail. A storage frame is movably connected to one end of the synchronous slide rail located on the driven slide rail. The storage frame is rotatably connected to the outside of the ultrasonic flaw detector body through the synchronous slide. A light-shielding cover body is movably connected in the storage frame. An arc-shaped end is fixedly installed at one end of the light-shielding cover body that extends outside the storage frame, and the arc-shaped end abuts against the ultrasonic flaw detector body.

[0007] As an improved technical solution, the synchronous slide is composed of a driven slider, a driving slider, and a synchronous plate. The synchronous plate is arranged to avoid each other with respect to the driving and driven slides. The driven slider and the driving slider are respectively fixedly installed at both ends of the synchronous plate, and the driven slider and the driving slider are respectively movably connected in the driven and driven slides. The end of the storage rack near the ultrasonic flaw detector body is hinged to the corresponding driven slider.

[0008] As an improved technical solution, the hinge between the storage rack and the driven slider is further provided with an inclined telescopic inner rod and a guide sleeve. The telescopic inner rod is slidably distributed along the axial direction of the guide sleeve. The end of the telescopic inner rod protruding from the guide sleeve is hinged to a transmission link, and the end of the transmission link away from the telescopic inner rod is hinged to the corresponding active slider.

[0009] As an improved technical solution, the ultrasonic flaw detector body has a first arc-shaped groove adapted to the arc-shaped end at one end near the storage rack, and a second arc-shaped groove adapted to the arc-shaped end is also provided on the side of the ultrasonic flaw detector body near the display area, and the angle between the first arc-shaped groove and the second arc-shaped groove is ninety degrees.

[0010] As an improved technical solution, the active slide rail and the driven slide rail are vertically distributed on both sides of the ultrasonic flaw detector body. An adjusting screw is also rotatably connected in the active slide rail, and the end of the adjusting screw that protrudes from the active slide rail is provided with a screw. The end of the adjusting screw that extends into the active slide rail is threadedly connected to the active slider.

[0011] As an improved technical solution, a vertically distributed guide slide rod is fixedly installed in the driven slide rail, and a hole corresponding to the guide slide rod is opened in the driven slider. The guide slide rod extends through one end of the driven slider to the outside of the driven slide rail, and the driven slider slides along the axial direction of the guide slide rod through the hole.

[0012] As an improved technical solution, the main body of the light shield extends to one end of the storage rack and has an opening for avoiding the driven slide rail. The opening corresponds to the driven slide rail and is symmetrically distributed at both ends of the arc-shaped end.

[0013] As an improved technical solution, the main body of the light shield is also provided with a limiting hole corresponding to the opening, and the limiting hole is adapted to one end of the guide slide rod protruding from the driven slide rail.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: 1. This utility model, through the flip-out design of the storage rack around the driven slider pin shaft, combined with the telescopic function of the main body of the light shield along the storage rack, effectively enhances the light shielding range and light shielding sealing, and solves the problems of narrow light shielding range and light leakage in the gaps of the fixed cover plate.

[0015] 2. This utility model utilizes the insertion and cooperation of the limiting hole of the light shield and the guide slide rod to fix the flip angle and extension position, ensuring the stability of the light shielding mechanism during the testing process and further guaranteeing the reliability of the light shielding state.

[0016] 3. This utility model uses a trapezoidal threaded adjusting screw with a self-locking function inside the active slide rail to drive the active slider to slide, which in turn drives the driven slider and the storage rack and the main body of the light shield to move up and down as a whole, so as to realize the light shielding height can be adjusted as needed. It can also cover the speaker area or display area by extending and retracting the light shield when the device is not flipped over and the flaw detector is not working. Attached Figure Description

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0025] like Figure 1-6As shown in the figure, this embodiment provides a light-shielding device for an ultrasonic flaw detector. This device includes an ultrasonic flaw detector body 1, which has a button area 2, a speaker area 4, and a display area 3. The ultrasonic flaw detector body 1 also has a deflectable light-shielding mechanism, which includes an active slide rail 5 and a driven slide rail 6 detachably mounted on the ultrasonic flaw detector body 1. A synchronous slide 7 is movably connected between the active slide rail 5 and the driven slide rail 6. The synchronous slide 7 is located at... One end of the driven slide rail 6 is movably connected to a storage rack 8, and the storage rack 8 is rotatably connected to the outside of the ultrasonic flaw detector body 1 via a synchronous slide 7. A light shield body 9 is movably connected in the storage rack 8, and an arc-shaped end 901 is fixedly installed at one end of the light shield body 9 extending outside the storage rack 8. The arc-shaped end 901 abuts against the ultrasonic flaw detector body 1. The ultrasonic flaw detector body 1 serves as the base of the whole machine and is provided with a composite slide groove, or a hard rubber sleeve is provided on the outside of the active slide rail 5 and the driven slide rail 6 to the ultrasonic flaw detector body 1. This design can meet the installation requirements of different models of flaw detectors. When in use, it is attached to the ultrasonic flaw detector body 1 in a phone case style. It can be disassembled and installed in conjunction with the active slide rail 5 and the driven slide rail 6, thus avoiding interference from the protruding structure on the normal carrying of the ultrasonic flaw detector body 1. It realizes the convenient disassembly and assembly of the light shielding mechanism as a whole. It is only used when light shielding is required. The synchronous slide 7 is in a fixed state when in use. The storage rack 8 can rotate around the pin shaft of the driven slider 701, thereby completing the flipping out or retraction of the light shield body 9. The telescopic design of the light shield body 9 is adapted to different display area 3 sizes, which can effectively eliminate the gap caused by the fixed size. The arc structure of the arc end 901 improves the fit with the body and prevents the light shield body 9 from being completely submerged in the storage rack 8. It can also achieve seamless light shielding when in contact, blocking the light leakage path of the gap.

[0026] The synchronous slide 7 is composed of a driven slider 701, an active slider 702, and a synchronous plate 703. The synchronous plate 703 is arranged to avoid interference with the active slide rail 5 and the driven slide rail 6. The driven slider 701 and the active slider 702 are respectively fixedly installed at both ends of the synchronous plate 703, and the driven slider 701 and the active slider 702 are respectively movably connected in the driven slide rail 6 and the active slide rail 5. The end of the storage frame 8 near the ultrasonic flaw detector body 1 is hinged to the corresponding driven slider 701. The synchronous plate 703 can realize the synchronous sliding of the driven slider 701 and the active slider 702 and avoid component interference during movement, ensuring smooth sliding. The hinged structure between the storage frame 8 and the driven slider 701 allows the storage frame 8 to follow the height change of the driven slider 701 and rotate around the driven slider 701, providing freedom for adjusting the light-shielding direction.

[0027] At the hinge between the storage rack 8 and the driven slider 701, there are also inclined telescopic inner rods 10 and guide sleeves 11. The telescopic inner rods 10 slide along the axial direction of the guide sleeves 11. The end of the telescopic inner rod 10 protruding from the guide sleeves 11 is hinged to a transmission link 12, and the end of the transmission link 12 away from the telescopic inner rod 10 is hinged to the corresponding active slider 702. The telescopic inner rod 10 and the guide sleeves 11 together constitute a telescopic support assembly, which has both support and guidance functions. The sliding mating surface is lubricated to reduce frictional resistance. The transmission link 12 pulls the telescopic inner rod 10 to extend and retract within the guide sleeves 11, thereby driving the storage rack 8 to rotate around the driven sliders 701 to achieve the adjustment of the light-blocking angle.

[0028] The ultrasonic flaw detector body 1 has a first arc-shaped groove 101 that matches the arc-shaped end 901 at one end near the storage rack 8, and a second arc-shaped groove 102 that matches the arc-shaped end 901 is also provided on the side of the ultrasonic flaw detector body 1 near the display area 3. The angle between the first arc-shaped groove 101 and the second arc-shaped groove 102 is 90 degrees. When the arc-shaped end 901 is located in the first arc-shaped groove 101, it is in an unshielded state. When it is located in the second arc-shaped groove 102, it is in a shielded state. The arc-shaped end 901 can achieve fitting and limiting within a horizontal or vertical range, covering the main shielding direction from the front to the top of the display area 3. At the same time, through the cooperation of the arc-shaped groove and the arc-shaped end 901, the gap at the fitting point is eliminated, and external light is completely blocked from penetrating from the edge.

[0029] The active slide rail 5 and the driven slide rail 6 are vertically distributed on both sides of the ultrasonic flaw detector body 1. An adjusting screw 501 is rotatably connected in the active slide rail 5, and the end of the adjusting screw 501 that protrudes from the active slide rail 5 is provided with a screw. The end of the adjusting screw 501 that extends into the active slide rail 5 is threadedly connected to the active slider 702. The length of the active slide rail 5 and the driven slide rail 6 depends on the height range that the synchronous slide 7 can cover when it slides up and down. The adjusting screw 501 has a self-locking function to prevent the active slider 702 from sliding on its own. The screw is easy to operate manually and has anti-slip texture on the surface to improve the convenience of holding and operating. The operator rotates the screw to drive the adjusting screw 501 to rotate, and uses the thread transmission to drive the active slider 702 to slide up and down along the active slide rail 5 to realize the height adjustment of the storage rack 8.

[0030] Vertically distributed guide rods 601 are fixedly installed in the driven slide rail 6, and holes corresponding to the guide rods 601 are opened in the driven slider 701. The guide rods 601 extend through one end of the driven slider 701 to the outside of the driven slide rail 6. The driven slider 701 slides along the axial direction of the guide rods 601 through the holes. The inner wall of the holes of the driven slider 701 is provided with wear-resistant bushings to reduce sliding friction loss. The guide rods 601 provide precise guidance for the movement of the driven slider 701, ensuring its synchronous movement accuracy with the active slider 702, preventing the synchronous slide 7 from tilting, and ensuring the overall stability of the light-shielding mechanism.

[0031] The sunshade body 9 extends to one end of the storage rack 8 and has an opening 902 for avoiding the driven slide rail 6. The opening 902 corresponds to the driven slide rail 6 and is symmetrically distributed at both ends of the arc end 901. The size and shape of the opening 902 are perfectly matched to the cross section of the driven slide rail 6 to avoid interference between the sunshade body 9 and the slide rail when it is extended or retracted. The symmetrical distribution ensures that the sunshade body 9 is subjected to balanced force and is not easy to deviate when it is extended or retracted.

[0032] The main body 9 of the light shield is also provided with a limiting hole 903 corresponding to the opening 902. The limiting hole 903 is adapted to the end of the guide slide rod 601 that protrudes from the driven slide rail 6. When the light shield is flipped, the main body 9 of the light shield extends and retracts along the storage rack 8 due to gravity. The limiting hole 903 can be inserted into the guide slide rod 601 to further ensure the stability of its angle after flipping.

[0033] During the use of this device for light shielding, the light shielding direction is switched by rotating the angle of the storage rack 8: the synchronous slide 7 remains fixed during use. By pulling the transmission link 12 backward, the storage rack 8 can rotate around the pin connected to the driven slider 701. During the rotation, the position of the active slider 702 is fixed, and the telescopic inner rod 10 slides axially along the guide sleeve 11. When the arc end 901 rotates from the first arc groove 101 of the ultrasonic flaw detector body 1, the light shield body 9 is completely retracted into the storage rack 8. When it rotates to the second arc groove 102, the storage rack 8 simultaneously completes a 90-degree rotation, driving the light shield body 9 from the "retracted and idle" state to the light shielding direction "facing the display area 3", covering the main light source direction from the front to the top of the display area 3. After being flipped to the light-shielding direction, the telescopic characteristics of the light-shielding body 9 are used to adapt to the size of the display area 3: the light-shielding body 9 can freely extend and retract along the storage rack 8. According to the actual size of the display area 3, the operator pushes the light-shielding body 9 out of the storage rack 8. During the extension and retraction process, the opening 902 at the end of the light-shielding body 9 is fully adapted to the driven slide rail 6 to avoid interference between the two. At the same time, the arc structure of the arc end 901 will fit with the inner wall of the second arc groove 102 of the ultrasonic flaw detector body 1. The flexible sealing gasket in the groove further fills the fitting gap and completely blocks the external light from seeping in from the edge. Meanwhile, after the main body 9 of the light shield extends or retracts to its final position, its limiting hole 903 will precisely engage with one end of the guide slide rod 601 that protrudes from the driven slide rail 6. When the main body 9 of the light shield tends to slide along the storage rack 8 due to gravity, the engagement of the limiting hole 903 and the guide slide rod 601 will restrict its sliding and further fix the flip angle of the storage rack 8, ensuring that the entire light shielding mechanism maintains a stable light shielding state during the testing process. When the light-shielding position needs to be adjusted according to the operator's viewing angle or the height of the display area 3, the height adjustment is achieved through the drive structure of the active slide rail 5. The operator rotates the anti-slip screw part of the protruding end of the adjusting screw 501, which drives the adjusting screw 501 to rotate in the bearing of the active slide rail 5. Since the adjusting screw 501 and the active slider 702 are threaded together, and the screw is designed with a trapezoidal thread and has a self-locking function, the thread transmission will be converted into the active slider 702 sliding vertically along the active slide rail 5. At the same time, the active slider 702 drives the driven slider 701 to slide synchronously along the guide slide rod 601 in the driven slide rail 6 through the synchronous plate 703, which in turn drives the storage rack 8 and the light shield body 9 to move up and down as a whole until the light-shielding height required for the display area 3 is covered. Thus, even when not flipped, the light shield body 9 can also shield the speaker area 4 or the display area 3 through its own extension and retraction. However, at this time, the ultrasonic flaw detector body 1 should be in a non-working state. The light-shielding mechanism adopts a detachable design. It can be flexibly adapted to the ultrasonic flaw detector body 1 by using a "phone case-like external attachment" design with hard rubber sleeves on the outside of the active slide rail 5 and the driven slide rail 6. No structural modification of the flaw detector body is required. Alternatively, the entire light-shielding mechanism can be externally attached to the ultrasonic flaw detector body 1 through the pre-set composite slide groove on the ultrasonic flaw detector body 1, which enables quick disassembly and installation of the light-shielding mechanism. When not in use for light shading, the entire light-shielding mechanism can be removed to avoid the protruding structure interfering with the normal carrying of the flaw detector. The mechanism is installed only when light shading is required (such as in strong light environment detection) to meet the needs of scenario-based use.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
