Description
Technical Field
[0001] This utility model relates to the field of ultrasonic testing technology, and in particular to an ultrasonic testing device. Background Technology
[0002] Non-destructive testing (NDT) is a technique that uses principles and technologies such as radiography, ultrasound, infrared radiation, and electromagnetics, combined with instruments, to detect defects, chemical parameters, and physical properties of materials, parts, and equipment without damaging or affecting their performance. Ultrasonic testing is an important NDT method. Ultrasonic waves have good directivity, allowing them to propagate in a straight line in a specific direction. However, they experience attenuation and scattering during propagation in a medium. At interfaces between dissimilar media, they undergo reflection, refraction, and wave mode conversion. Ultrasonic testing typically requires an ultrasonic testing instrument and a testing probe.
[0003] The inventors believe that the following drawbacks often exist: Ultrasonic testing is an important non-destructive testing method. Ultrasonic testing often requires the use of an ultrasonic testing instrument and a testing probe. When workers need to probe in a small space, the probe body is too short to be inserted into the small probe position, which makes it difficult for the probe body to probe the specified target in a narrow space, thus affecting the work efficiency of workers; therefore, an ultrasonic testing device is proposed to address the above problems. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the short length of the probe body, which makes it difficult to insert into a small detection position, thus making it difficult for the probe body to detect a target in a narrow space, thereby affecting the work efficiency of the staff. Therefore, an ultrasonic detection device is proposed.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an ultrasonic testing device, comprising a probe body and a testing instrument, wherein a connecting wire is installed at one end of the probe body, and the end of the connecting wire away from the probe body is electrically connected to the testing instrument; a plurality of control buttons are installed on the surface of the testing instrument; an extension device is provided on the arc surface of the probe body; the extension device includes a fixing ring, the fixing ring being fixedly connected to the arc surface of the probe body; an L-shaped plate is fixedly connected to the arc surface of the fixing ring; an extension chamber is slidably connected to the surface of the L-shaped plate; and a fixing rod is fixedly connected to one side of the extension chamber.
[0006] An operating plate is slidably connected to the arc surface of the fixed rod, and an insertion rod is fixedly connected to one side of the operating plate. Several insertion holes are opened on the surface of the L-shaped plate.
[0007] The effect achieved by the above-mentioned components is as follows: by setting up the extension device, the length of the probe body is extended, which avoids the situation where the probe body is too short to be inserted into the small detection position when the staff needs to detect in a small space. This would make it difficult for the probe body to detect the specified target in a narrow space, thus affecting the work efficiency of the staff and improving the practicality of the device.
[0008] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the extension chamber, and the size of the insertion rod is adapted to the size of the L-shaped plate insertion hole.
[0009] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force caused by the operator's difficulty in controlling the pulling force.
[0010] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the extension compartment, respectively.
[0011] The effect achieved by the above components is that the first spring improves the stability of the insertion rod when the extension chamber is extended, and reduces the impact of external vibrations on the device.
[0012] Preferably, anti-slip pads are fixedly connected to both sides of the extension compartment, and the surface of the anti-slip pads is provided with a number of anti-slip protrusions.
[0013] The aforementioned components achieve the following effect: preventing the extension chamber from slipping out of the operator's hands, thus avoiding the situation where the extension chamber slips out of the operator's hands, causing the probe body to fall to the ground and be damaged.
[0014] Preferably, the surface of the detector is provided with a protective device, which includes two support blocks. Both support blocks are fixedly connected to the surface of the detector. A rotating rod is fixedly connected to one side of the two support blocks that are close to each other. A protective plate is rotatably connected to the arc surface of the rotating rod. Two U-shaped frames are fixedly connected to the surface of the protective plate. A threaded rod is fixedly connected to the upper surface of the detector. An insert plate is slidably connected to the arc surface of the threaded rod.
[0015] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the control buttons are protected, which prevents dust from accumulating on the surface of the detector when it is idle for a long time. This prevents a large amount of dust from entering the detector through the control buttons, which could lead to malfunction of the control buttons or reduced internal heat dissipation, thus improving the protection of the device.
[0016] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the support block and the protective plate, respectively.
[0017] The effect achieved by the above components is that the torsion spring automatically opens the protective plate, thereby reducing the number of steps required for operators to operate the device and improving their work efficiency.
[0018] Preferably, the arc surface of the threaded rod is threadedly connected to a threaded block, and the upper surface of the threaded block is slidably connected to the insert plate.
[0019] The effect achieved by the above components is that the threaded block limits the insertion plate, preventing the insertion plate from being too low due to gravity, which would affect the operator's ability to view the testing instrument.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] 1. In this utility model, by setting an extension device, the length of the probe body is extended, which avoids the situation where the probe body is too short to be inserted into a small detection position when the staff needs to detect a small space. This would make it difficult for the probe body to detect the target in a narrow space, thus affecting the work efficiency of the staff and improving the practicality of the device.
[0022] 2. In this utility model, by setting a protective device, the control buttons are protected, which prevents dust from accumulating on the surface of the detector when it is idle for a long time. This prevents a large amount of dust from entering the detector through the control buttons, which could lead to malfunction of the control buttons or reduced internal heat dissipation, thus improving the protective performance of the device.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: an ultrasonic testing device, including a probe body 1 and a detector 2. A connecting wire 3 is installed at one end of the probe body 1, and the end of the connecting wire 3 away from the probe body 1 is electrically connected to the detector 2. Several control buttons 4 are installed on the surface of the detector 2. An extension device 5 is provided on the arc surface of the probe body 1. By setting the extension device 5, the length of the probe body 1 is extended, avoiding the situation where the probe body 1 is too short to insert into a small detection position when the operator needs to detect in a small space, thus making it difficult for the probe body 1 to detect a target in a narrow space, thereby affecting the operator's work efficiency and improving the practicality of the device. A protective device 6 is provided on the surface of the detector 2. By setting the protective device 6, the control buttons 4 are protected, preventing dust from accumulating on the surface of the detector 2 when it is idle for a long time. A large amount of dust enters the detector 2 through the dust on the control buttons 4, causing the control buttons 4 to malfunction or the internal heat dissipation effect to be reduced, thus improving the protection of the device.
[0032] The specific configuration and function of its extension device 5 and protective device 6 will be explained in detail below.
[0033] Reference Figure 2 and Figure 3 As shown in this embodiment: the extension device 5 includes a fixing ring 51, which is fixedly connected to the arc surface of the probe body 1. An L-shaped plate 52 is fixedly connected to the arc surface of the fixing ring 51. An extension chamber 53 is slidably connected to the surface of the L-shaped plate 52. A fixing rod 54 is fixedly connected to one side of the extension chamber 53. An operating plate 55 is slidably connected to the arc surface of the fixing rod 54. An insertion rod 56 is fixedly connected to one side of the operating plate 55. Several insertion holes are opened on the surface of the L-shaped plate 52. A limit plate 57 is fixedly connected to the end of the fixing rod 54 away from the extension chamber 53.
[0034] The size of the insertion rod 56 is matched with the size of the insertion hole of the L-shaped plate 52. When the operator pulls the operating plate 55, the operating plate 55 slides on the arc surface of the fixed rod 54. At this time, the limiting plate 57 achieves the effect of limiting the maximum sliding distance of the operating plate 55 on the arc surface of the fixed rod 54, avoiding the situation where the operator pulls the operating plate 55 with excessive force due to difficulty in controlling the pulling force, thus causing the operating plate 55 to detach from the arc surface of the fixed rod 54. The arc surface of the fixed rod 54 is fitted with a first spring 58, and the two ends of the first spring 58 are fixedly connected to the operating plate 55 and the extension compartment 53 respectively. When the operator releases the spring 58, the operating plate 55 will slide on the arc surface of the fixed rod 54. When the operating plate 55 is activated, the rebound force of the first spring 58 causes the operating plate 55 to slide on the arc surface of the fixed rod 54. At the same time, the operating plate 55 drives the insertion rod 56 to move until the insertion rod 56 is inserted into the insertion hole of the L-shaped plate 52. At this time, the first spring 58 improves the stability of the insertion rod 56 in fixing the extension chamber 53 during extension, reducing the impact of external vibration on the device. Anti-slip pads 59 are fixedly connected to both sides of the extension chamber 53. The surface of the anti-slip pads 59 is provided with several anti-slip protrusions, which achieves the effect of preventing the extension chamber 53 from falling out of the operator's hand, thus avoiding the situation where the extension chamber 53 falls out of the operator's hand and the probe body 1 falls to the ground and is damaged.
[0035] Reference Figure 4 , Figure 5 and Figure 6 As shown, specifically, the protective device 6 includes two support blocks 61, both of which are fixedly connected to the surface of the detector 2. A rotating rod 62 is fixedly connected to one side of the two support blocks 61 that is close to each other. A protective plate 63 is rotatably connected to the arc surface of the rotating rod 62. Two U-shaped brackets 64 are fixedly connected to the surface of the protective plate 63. A threaded rod 65 is fixedly connected to the upper surface of the detector 2. An insert plate 66 is slidably connected to the arc surface of the threaded rod 65. Two torsion springs 67 are sleeved on the arc surface of the rotating rod 62. The two ends of the torsion springs 67 are fixedly connected to the support blocks 61 and the protective plate 63, respectively. When the operator releases the limit of the insert plate 66 on the protective plate 63, the torque of the torsion springs 67 drives the protective plate 63 to rotate on the arc surface of the rotating rod 62 until the protective plate 63 is fully opened.
[0036] At this time, the torsion spring 67 automatically opens the protective plate 63, which reduces the number of steps required for the operator to operate the device and improves the operator's work efficiency. The threaded rod 65 has a threaded block 68 connected to its arc surface. The upper surface of the threaded block 68 is slidably connected to the insert plate 66. At this time, the threaded block 68 achieves the effect of limiting the position of the insert plate 66, preventing the insert plate 66 from being too low due to gravity, which would affect the operator's ability to view the detector 2.
[0037] Working principle: When the operator needs to use the probe body 1 to probe a relatively narrow detection position, pull the operating plate 55, causing it to slide on the arc surface of the fixed rod 54. The first spring 58 is stretched, and at the same time, the operating plate 55 drives the insertion rod 56 to move until the insertion rod 56 disengages from the insertion hole of the L-shaped plate 52. At this time, pull the anti-slip pad 59, which drives the extension chamber 53 to slide on the surface of the L-shaped plate 52 until the extension chamber 53 extends to a sufficient length. Then, release the operating plate 55. The rebound force of the first spring 58 drives the operating plate 55 to slide on the arc surface of the fixed rod 54, and at the same time, the operating plate 55 drives the insertion rod 56 to move until the insertion rod 56 is inserted into the insertion hole of the L-shaped plate 52. This achieves the effect of extending the length of the probe body 1, avoiding the situation where the probe body 1 is too short to insert into a narrow detection position when the operator needs to probe a small space. This prevents the probe body 1 from being unable to probe a narrow target, thus affecting the operator's work efficiency and improving the practicality of the device.
[0038] When staff need to protect the control button 4 on the idle detector 2 from dust, they press the protective plate 63. The protective plate 63 rotates on the arc surface of the rotating rod 62 until it completely covers the control button 4. At this time, the threaded block 68 is rotated, causing it to move downwards on the arc surface of the threaded rod 65. Simultaneously, the threaded block 68 no longer supports the insert plate 66, and the insert plate 66 moves downwards with the threaded block 68 under the influence of gravity until it is inserted into the U-shaped frame 64. This achieves the effect of protecting the control button 4, preventing dust from accumulating on the surface of the detector 2 during long periods of idleness. This also prevents a large amount of dust from entering the detector 2 through the dust on the control button 4, which could lead to the control button 4 malfunctioning or reduced internal heat dissipation, thus improving the device's protective performance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
