Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, specifically to a portable flaw detector. Background Technology

[0002] Flaw detectors are widely used in non-destructive testing of metallic materials. They are mainly used to detect defects inside or on the surface of metal structures, such as cracks, porosity, inclusions, and debonding. Traditional flaw detectors are usually large and heavy, and have certain limitations in terms of portability and ease of use, making it difficult to meet the testing needs in complex environments. Therefore, in order to improve the applicability of flaw detectors, portable flaw detectors have gradually appeared on the market, so that engineers can operate them flexibly in various environments and improve testing efficiency.

[0003] Current portable flaw detectors mostly employ ultrasonic, eddy current, or magnetic particle testing technologies. Among them, ultrasonic flaw detectors utilize the characteristic that high-frequency sound waves reflect off defects when they encounter them within metallic materials to detect defects, making them suitable for the inspection of most metallic materials. Eddy current flaw detectors are mainly used to detect surface or near-surface defects in conductive materials and are suitable for the inspection of thin-walled metallic components. Magnetic particle flaw detectors utilize the effect of magnetic fields to detect surface or near-surface defects in ferromagnetic materials. Different types of flaw detection technologies have their own advantages and disadvantages, and the appropriate detection method usually needs to be selected based on the actual application scenario.

[0004] Currently, there is still room for improvement in the structural design of portable flaw detectors on the market. For example, the carrying method of the equipment is relatively simple, and battery replacement is relatively complicated, which affects the continuity of inspection work. In addition, in order to improve the processing capability of flaw detection data, modern flaw detectors usually integrate data management software to facilitate data storage, analysis and visualization, thereby improving inspection efficiency and accuracy.

[0005] To address the aforementioned issues, this application proposes a portable flaw detector. By optimizing the casing design, adding multiple carrying methods, and improving the battery disassembly and assembly structure, the device's portability, stability, and ease of operation are enhanced, meeting the flaw detection needs of engineers in different environments.

Therefore, they should not be construed as limitations on this utility model.

[0040] This application proposes a portable flaw detector, as detailed below;

[0041] For reference Figure 1 This application mainly consists of an outer shell 1, a rear shell 2 which can be disposed on the back of the outer shell 1, a battery 3 fixedly connected to the rear shell 2, a connector 4 for fastening the rear shell 2 to the outer shell 1, a threaded shaft 401 for engaging the connector 4, a receiving part 5 for engaging with the connector 4, and a detachable plastic strap 6. Through the coordinated arrangement of the above structures, the device can be made more convenient in terms of battery installation and removal, overall carrying and reducing the loss of parts, and is more conducive to user operation.

[0042] For reference Figure 1 The outer shell 1 is the external protective shell of the device, which is made of automotive-grade impact-resistant material.

[0043] The outer casing 1 is divided into left and right sides, with an electronic screen 11 on one side and a button on the other side; PRO data management software is installed in the inner cavity of the outer casing 1 corresponding to the electronic screen 11, which is used for processing detection data; the above settings are common in the existing field and will not be described in detail in this application.

[0044] Furthermore, its electronic screen 11 adopts a color VGA display to ensure that the instrument can be clearly displayed under any lighting conditions.

[0045] Furthermore, to make the device convenient for desktop support, hand carrying, and shoulder strap use without interfering with each other, optimizations have been made. A folding bracket 13 is provided in the middle of the back of the outer shell 1. The folding bracket 13 is rotatable and can be opened by rotating to form a triangular connection with the back of the outer shell 1 for support on a desktop. When not in use, it can be rotated back to its original position. Two shoulder strap buckles 14 are provided on one edge of the back of the outer shell 1. The two shoulder strap buckles 14 are symmetrically arranged and can be used to connect to a backpack strap, which can help engineers carry the device in the required environment. In addition, a plastic strap 6 is provided on the edge of the back of the outer shell 1 where the shoulder strap buckles 14 are symmetrically located, so that the device can be carried by hand.

[0046] For reference Figure 1-3 To avoid conflict between the backpack strap connected to the shoulder strap buckle 14 and the plastic strap 6 during use, the plastic strap 6 is designed as a detachable structure. One end of the plastic strap 6 is connected to the bottom of the outer shell 1 with a screw, and the other end is snapped into the middle of the connection between the back shell 2 and the outer shell 1. Thus, during disassembly and assembly, the plastic strap 6 can be completely removed after disassembling the back shell 2 and removing the other end fixed by the screw. The disassembly and assembly method is simple and convenient, which is conducive to engineers to switch and use it according to the scenario.

[0047] For reference Figure 2-4 To simplify the installation and removal of the battery used in the device, the battery 3 and the back cover 2 are integrated; thus, the battery 3 can be installed and removed simultaneously when the back cover 2 is installed and removed, eliminating the need to install and remove the battery 3 again.

[0048] Specifically, to facilitate the connection between the outer shell 1 and the back shell 2 and the battery 3, a groove 12 is provided on the back of the outer shell 1. The groove 12 is adapted to the connection surface of the back shell 2 and the battery 3. In order to better prevent the battery 3 from shifting after installation, a protruding shaft 21 is provided on one side of the back shell 2. The groove 12 is designed to include area A 121 and area B 122. Area A 121 is square-shaped and adapted to the size of the battery 3. Area B 122 is cloud-shaped and has more contact surface after being adapted to the protruding shaft 21, thereby increasing resistance. The locking and positioning of area B 122 and protruding shaft 21 reduces the possibility of the battery 3 shaking after installation.

[0049] Meanwhile, it should be noted that when the back cover 2 is placed on the back of the outer shell 1 corresponding to the groove 12, the battery 3 and its convex shaft 21 are adapted to the groove 12 for connection; secondly, a locking block is provided at the bottom of the outer shell 1 for basic locking and fixing; to further improve the stability of the connection and fixing of the back cover 2, a receiving part 5 and a connecting part 4 are provided; through the cooperation of the connecting part 4 and the receiving part 5, the battery 3 can be made to be located in the groove 12, which can better make the electrode terminals of the battery 3 correspond to the positions set in the groove 12, reducing the occurrence of gaps and disconnections.

[0050] For reference Figure 5 The receiving component 5 includes an outer frame 51 and an inner groove 52. The bottom of the outer frame 51 is embedded in the rear shell 2. The inner groove 52 is opened in the middle of the outer frame 51. The threaded shaft 401 protrudes in the middle of the inner surface of the inner cavity of the inner groove 52. The diameter of the threaded rod 43 is adapted to the diameter of the inner groove 52.

[0051] When the connector 4 penetrates the rear shell 2 and enters the receiving part 5, the receiving part 5 located on the back of the outer shell 1 is connected to it; the connector 4 first penetrates the rear shell 2 and then enters the receiving part 5. The outer frame 51 is convex, and the convex part is adapted to and snapped into the connecting end of the rear shell 2, which can increase the stability of the connection; when the threaded rod 43 enters the outer frame 51, it will enter the inner groove 52, thereby completing the connection relationship between the receiving part 5 and the connector 4.

[0052] For reference Figure 5 To avoid the problem of connector 4 being difficult to store and easily lost during disassembly and assembly, further modifications are made to connector 4 and its pre-fabricated rear shell 2. Connector 4 is configured to include a torsion cap 41, a connecting rod 42, and a threaded rod 43. One end of the connecting rod 42 is connected to the torsion cap 41, and the other end is connected to the threaded rod 43. The diameter of the connecting rod 42 is smaller than that of the torsion cap 41 and the threaded rod 43. During use, a plastic pad is added to the connecting rod 42 to provide shock absorption and prevent loosening at the connection point.

[0053] A threaded shaft 401 is installed in the circular groove through which the connector 4 passes through the rear shell 2. At this time, during connection, the threaded rod 43 is first inserted into the circular groove, and then the threaded rod 43 is threadedly connected to the threaded shaft 401 until all parts of the threaded rod 43 are connected to the threaded shaft 401, and then it passes out of the circular groove and is connected to the receiving part 5. Since the threaded shaft 401 is protruding, the maximum diameter of the inner cavity of the threaded shaft 401 will be smaller than the maximum diameter of the threaded rod 43. At this time, resistance will be generated when the threaded rod 43 is not twisted. The diameter of the torsion cap 41 is also larger than that of the connecting rod 42. The diameter of the connecting rod 42 is matched with the size of the threaded shaft 401. Therefore, the diameter of the torsion cap 41 is larger than that of the threaded shaft 401. When the connector 4 passes through the circular groove, the resistance formed by the threaded rod 43 and the torsion cap 41 at both ends reduces the risk of the connector 4 falling off the rear shell 2.

[0054] In this invention, the working steps of the device are as follows:

[0055] 1. First, select the folding bracket 13, shoulder strap buckle 14 and plastic strap 6 according to the usage situation, or they can be used together;

[0056] 2. Next, engage the rear shell 2 with battery 3 with the groove 12 on the outer shell 1. After engaging, insert the connector 4 into the round groove inside the rear shell 2. First, thread the threaded rod 43 to the threaded shaft 401 until the threaded shaft 401 is connected to the connecting rod 42.

[0057] 3. Then, move the connector 4 downwards until the threaded shaft 401 contacts the receiving part 5 to complete the threaded connection;

[0058] 4. Finally, after the connection is completed, the internal power is turned on. At this time, the button on the outer shell 1 is used to operate, and the data is processed by the PRO data management software and displayed on the electronic screen 11.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
