Description

Technical Field

[0001] This utility model relates to the field of flaw detection equipment, and in particular to a portable ultrasonic flaw detection device. Background Technology

[0002] Ultrasonic testing technology is widely used in many fields such as industrial inspection and building quality assessment because it can detect internal defects in materials non-destructively.

[0003] Traditional equipment typically requires inspectors to hold the ultrasonic probe directly to the object being inspected. While this method is sufficient for some routine and easily accessible inspection points, it becomes problematic when dealing with complex structures, such as narrow spaces, high places, or irregularly shaped areas. In such cases, inspectors struggle to hold the probe stably and maintain the appropriate inspection angle and distance, leading to extremely inconvenient operation. This not only increases the difficulty and time cost of inspection but may also affect the accuracy and reliability of the results due to operational instability. Therefore, those skilled in the art are dedicated to developing a portable ultrasonic flaw detection device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable ultrasonic flaw detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable ultrasonic flaw detection device includes a support base and an ultrasonic detector. A mounting frame is fixedly connected to the upper surface of the support base. A sleeve rod is fixedly connected to the front of the mounting frame. One end of the sleeve rod is rotatably connected to a threaded screw via a bearing. The other end of the threaded screw is threadedly fitted with a movable rod. A mounting block is fixedly connected to the other end of the movable rod. An ultrasonic probe is fixedly connected to the lower end of the mounting block. The ultrasonic detector is fixedly connected to the front of the mounting frame.

[0007] As a further improvement of this utility model, a knob is rotatably connected inside the mounting bracket via a bearing, and the knob is connected to a threaded screw.

[0008] As a further improvement of this utility model, a sliding groove is provided at the upper end of the sleeve rod, and a slider that matches the sliding groove is fixedly connected to the upper surface of one end of the movable rod.

[0009] As a further improvement of this utility model, the slider is slidably connected within the groove.

[0010] As a further improvement of this utility model, the lower end of the sleeve is fixedly connected with several hooks, and the hooks are provided with the same connecting line inside.

[0011] As a further improvement of this utility model, one end of the connecting wire is fixedly connected to the ultrasonic detector, and the other end of the connecting wire is fixedly connected to the ultrasonic probe.

[0012] As a further improvement of this utility model, a handle is fixedly connected to the front of the support base, and an anti-slip pad is provided on the surface of the handle.

[0013] As a further improvement of this utility model, the anti-slip mat is made of rubber.

[0014] As a further improvement of this utility model, the movable rod has a threaded hole inside that is compatible with the threaded screw.

[0015] As a further improvement of this utility model, the movable rod is movably connected inside the sleeve rod.

[0016] The device provided by this utility model has the following technical effects:

[0017] By setting up a movable rod, during use, the screw rod is rotated by turning a knob. Since the movable rod is threadedly connected to the screw rod, and the movable rod can only move linearly along the rod under the limiting action of the slider and the groove, it drives the mounting block and ultrasonic probe to move. This allows the testing personnel to accurately adjust the ultrasonic probe to various complex positions, improving the convenience and flexibility of the testing, effectively shortening the testing time, and improving the overall work efficiency.

[0018] By installing hooks, the connecting wires can be hung on them during use, which not only improves the aesthetics of the device but also effectively prevents damage to the connecting wires caused by careless placement, reduces the risk of accidents, protects the personal safety of testing personnel, and increases the safety of the device.

[0019] In summary, this utility model adopts a highly integrated design with a compact and ingenious overall structure, making it easy to move to different sites and flexibly handle different testing tasks, thus increasing the practicality of the device.

[0020] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

Detailed Implementation

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0028] like Figures 1-3 As shown, a portable ultrasonic flaw detection device includes a support base 1 and an ultrasonic detector 8. A mounting frame 2 is fixedly connected to the upper surface of the support base 1. A sleeve rod 3 is fixedly connected to the front of the mounting frame 2. One end of the sleeve rod 3 is rotatably connected to a threaded screw 4 through a bearing. The other end of the threaded screw 4 is threadedly sleeved with a movable rod 5. The other end of the movable rod 5 is fixedly connected to a mounting block 6. An ultrasonic probe 7 is fixedly connected to the lower end of the mounting block 6. The ultrasonic detector 8 is fixedly connected to the front of the mounting frame 2.

[0029] In this invention, a knob 9 is rotatably connected to the inside of the mounting bracket 2 via a bearing. The knob 9 is connected to the threaded screw 4, so that the rotation of the knob 9 can be directly transmitted to the threaded screw 4, causing the threaded screw 4 to rotate synchronously. This provides the power basis for the subsequent movement of the component through threaded transmission. A groove 10 is provided at the upper end of the sleeve rod 3. A slider 11 that matches the groove 10 is fixedly connected to the upper surface of one end of the movable rod 5. The slider 11 is slidably connected in the groove 10. This sliding connection structure restricts the movement direction of the movable rod 5, so that it can only move in a straight line along the direction of the groove 10, avoiding the movable rod 5 from deviating or rotating during the movement, thus improving the accuracy and reliability of the device.

[0030] Several hooks 12 are fixedly connected to the lower end of the sleeve rod 3. The hooks 12 are fixed to the sleeve rod 3 by welding and have a strong load-bearing capacity. They can stably hold the subsequent connecting line 13 and prevent the connecting line 13 from falling. The same connecting line 13 is set inside the several hooks 12. One end of the connecting line 13 is fixedly connected to the ultrasonic detector 8 and the other end of the connecting line 13 is fixedly connected to the ultrasonic probe 7. The connecting line 13 and the ultrasonic detector 8 are connected through a professional connection interface to ensure stable and accurate signal transmission. The signal detected by the ultrasonic probe 7 can be transmitted to the ultrasonic detector 8 for analysis and processing in a timely manner.

[0031] A handle 14 is fixedly connected to the front of the support base 1. The handle 14 is firmly installed on the front of the support base 1 by means of bolts or welding, providing an easy gripping part for the operator, making it easy to carry and move the entire device. The surface of the handle 14 is provided with an anti-slip pad 15. The anti-slip pad 15 is made of rubber. Rubber has good elasticity and anti-slip properties, which can provide stable friction in different environments, while also playing a certain role in cushioning, reducing the pressure between the hand and the handle 14, and improving the comfort of use.

[0032] The movable rod 5 has a threaded hole 16 inside that is compatible with the threaded screw 4. The thread specification of the threaded hole 16 matches the thread of the threaded screw 4. When the threaded screw 4 rotates, it can drive the movable rod 5 to make linear motion in the sleeve 3 through thread transmission, so as to realize the functional requirements of the device. The movable rod 5 is movably connected in the sleeve 3. There is a certain gap between the movable rod 5 and the sleeve 3. This ensures that the movable rod 5 can slide smoothly in the sleeve 3, and also avoids the movable rod 5 from shaking due to excessive gap, which would affect the accuracy and stability of the device.

[0033] When using this utility model, the operator first holds the handle 14 on the front of the support base 1 and moves the device to the vicinity of the part to be tested. Then, by rotating the knob 9 inside the mounting bracket 2, since the knob 9 is connected to the threaded screw 4 inside the sleeve rod 3 through a bearing, rotating the knob 9 will drive the threaded screw 4 to rotate. The other end of the threaded screw 4 is threadedly connected to a movable rod 5. The movable rod 5 has a threaded hole 16 that matches the threaded screw 4 and is movably connected to the sleeve rod 3. At the same time, a slider 11 is fixed to the upper surface of one end of the movable rod 5 in a sliding groove 10 at the upper end of the sleeve rod 3. The slider 11 is slidably connected in the sliding groove 10 and limits the movable rod 5, so that when the threaded screw 4 rotates, the movable rod 5 can only move linearly along the sleeve rod 3. As the movable rod 5 moves, the mounting block 6 fixedly connected to its other end and the ultrasonic probe 7 fixed at the lower end of the mounting block 6 will also move accordingly, adjusting the ultrasonic probe 7 to a suitable detection position. At this time, the ultrasonic detector 8 starts to work. The ultrasonic detector 8 sends a signal to the ultrasonic probe 7 through the connecting line 13. The ultrasonic probe 7 emits ultrasonic waves to perform flaw detection on the detection part and feeds back the detected signal to the ultrasonic detector 8 through the connecting line 13. The ultrasonic detector 8 analyzes and processes the signal to obtain the detection result.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
