[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0037] Tube banks are crucial components of boilers, pressure vessels, and ships. Due to harsh operating environments, they are prone to corrosion during use. If corrosion is not detected promptly, leaks can occur, posing a significant danger. Therefore, regular thickness checks of the tube banks are necessary to identify corrosion promptly. However, current handheld inspection devices, designed for easy storage and remote inspection of tube banks, often employ a sleeve structure for the support rod, inevitably leading to uneven rod thickness. This compromises the structural strength and stability of the support rod, consequently affecting the accuracy of the inspection results.

[0038] To solve the above problems, a connector and a locking component are set up. Adjacent rods are hinged by the connector, and the locking component can be moved to a first preset position and a second preset position to fix and flip adjacent rods. When in use, the locking component is moved to the first preset position, and when it needs to be stored, the locking component is moved to the second preset position. This ensures that the multiple rods of the support rod are of uniform thickness, improves the support stability of the support rod, and thus ensures the accuracy of the test results.

[0039] The following description, in conjunction with the accompanying drawings, details a handheld detection device with a foldable function provided in accordance with this application.

[0040] An exemplary embodiment of this application provides a handheld detection device with a foldable function, such as... Figures 1 to 5 As shown, the handheld detection device with foldable functionality includes a detection unit 100 and a support rod 200. The detection unit 100 is mounted on one end of the support rod 200 and is used for detection. The support rod 200 includes multiple rods 210 hinged together by connectors 220, i.e., both ends of the connectors 220 are respectively hinged to two adjacent rods 210. At least some of the rods 210 have locking members 230 at their ends, and the locking members 230 can move between a first preset position and a second preset position.

[0041] like Figure 2As shown, when the locking member 230 is in the first preset position, the locking member 230 is connected to both adjacent rods 210, and at this time the two adjacent rods 210 cannot rotate relative to each other; as Figure 3 As shown, when the locking member 230 is in the second preset position, the locking member 230 is connected to only one of the two adjacent rods 210. The two adjacent rods 210 can be flipped through the connecting member 220. The structure after flipping is as follows. Figure 5 As shown.

[0042] It should be noted that the locking element 230 can be provided at each end of each rod 210, or one can be provided at each end of a rod 210. In this case, there is no need to provide the locking element 230 on two adjacent rods 210. In addition, the number of locking elements 230 can be set according to the length required during actual use and storage, which will not be elaborated here.

[0043] The process of using the foldable handheld detection device in this embodiment is as follows: When it is to be used, the locking piece 230 on the rod 210 is moved to the first preset position. At this time, the adjacent rods 210 are locked and cannot rotate relative to each other. When it is to be stored after use, the locking piece 230 on the rod 210 is moved to the second preset position. At this time, the adjacent rods 210 can be flipped through the connector 220, realizing folding and storage.

[0044] By setting the connector 220 and the locking member 230, adjacent rods 210 are hinged through the connector 220. The locking member 230 is moved to the first preset position and the second preset position to fix and flip the adjacent rods 210. This ensures that the multiple rods 210 of the support rod 200 are of uniform thickness, improves the support stability of the support rod 200, and thus ensures the accuracy of the test results.

[0045] In some embodiments, reference Figures 1 to 3 The plurality of rods 210 include a first rod 2110 and a second rod 2120. A locking member 230 is disposed at one end of the first rod 2110. The second rod 2120 is connected to the end of the first rod 2110 where the locking member 230 is disposed via a connector 220, so that the locking member 230 is in a first preset position (e.g., Figure 2 As shown), the locking member 230 is connected to both the first rod 2110 and the second rod 2120, and is detachably connected to the second rod 2120; when the locking member 230 is in the second preset position (e.g. Figure 3 As shown, the locking member 230 can slide on the first rod 2110, and the sliding direction is parallel to the extension direction of the first rod 2110 (i.e., the x-axis direction in the figure).

[0046] In some embodiments, such as Figure 2 As shown, the detachable connection between the locking member 230 and the second rod 2120 in the first preset position can be any one or more of magnetic connection, snap-fit ​​connection and threaded connection. For example, a magnetic connection and snap-fit ​​connection that are easier to operate can be provided at the end closer to the detection part 100, and a more stable threaded connection can be used at the other end away from the detection part 100 because the rod 210 has a greater load-bearing capacity. The above-mentioned detachable connection methods can be selected by those skilled in the art according to actual needs, and all are within the protection scope of this application.

[0047] In some embodiments, such as Figure 2 As shown, both the second rod 2120 and the locking member 230 have matching threads at their detachable ends. The locking member 230 and the second rod 2120 are threaded together and rotatably connected to the first rod 2110. This design ensures the reliability of the connection and improves the overall structural strength of the support rod 200.

[0048] In some embodiments, continue to refer to Figure 2 and Figure 3 The locking element 230 is a sleeve. When the locking element 230 is in the first preset position, the connecting element 220 is located inside the sleeve. The sleeve-shaped locking element 230 can effectively prevent dust or other impurities from entering the connecting element 220 during the testing process and affecting the rotation performance of the connecting element 220, and also ensure the overall aesthetics of the support rod 200.

[0049] In other embodiments, the locking member 230 can also be configured as a strip-shaped slider. Both the first rod 2110 and the second rod 2120 are provided with grooves adapted to the strip-shaped slider. When the strip-shaped slider slides to a first preset position, the first rod 2110 and the second rod 2120 cannot rotate relative to each other due to the restriction of the strip-shaped slider. When the strip-shaped slider slides to a second preset position, the first rod 2110 and the second rod 2120 can be flipped via the connecting member 220. The position limitation of the strip-shaped slider can be achieved by a snap-fit. The form of the locking member 230 is not limited and is within the protection scope of this application.

[0050] In some embodiments, such as Figure 1 and Figure 4 As shown, the foldable handheld detection device also includes a grip 300, which is located at the end of the support rod 200 away from the detection unit 100. A display structure 310 is provided on the grip 300 and is electrically connected to the detection unit 100. The grip 300 facilitates better operation of the foldable handheld detection device by the operator, while the display structure 310, electrically connected to the detection unit 100, can display the data detected by the detection unit 100 in real time, allowing the operator to easily read the data.

[0051] In some embodiments, such as Figure 1 and Figure 4 As shown, the support rod 200 has a hollow structure. The connecting line between the display structure 310 and the detection unit 100 is located inside the support rod 200. With this design, the support rod 200 provides protection for the connecting line, preventing it from being exposed to the outside and subjected to corrosion or external impact.

[0052] In some embodiments, such as Figure 1 As shown, the display structure 310 is an electronic device. A groove is provided on the grip portion 300, and a rotating bracket 320 is disposed within the groove. The tilt angle of the rotating bracket 320 is adjustable, and the electronic device is detachably fixed to the rotating bracket 320. The electronic device may be, for example, a rugged mobile phone, and can be snapped onto the rotating bracket 320; this is not a limitation.

[0053] By setting up a rotating bracket 320 and an electronic device that is snapped onto the rotating bracket 320, the required electronic device and angle can be adjusted according to the actual situation. Other functions of the electronic device can also assist the operator in the inspection. For example, the electronic device can be used to store inspection data.

[0054] like Figure 4 As shown, the display structure 310 can also be a display screen, which is fixedly installed on the upper surface of the grip 300. The display screen saves costs compared to a display device.

[0055] In some embodiments, continue to refer to Figure 1 and Figure 4 The grip unit 300 also includes a controller, a memory, a button 330, and a battery. The controller and memory are located inside the grip unit 300. The button 330 is electrically connected to the controller and memory. The battery powers the entire foldable handheld detection device. The button 330 controls the power on / off of the foldable handheld detection device, turning it off when not in use to save power. Additionally, the button 330 controls the memory to store detected data. The functions of the button 330 can be differentiated by long and short presses, and multiple buttons 330 can be configured to achieve different functions.

[0056] In some embodiments, such as Figure 1 or Figure 5 As shown, the grip 300 is equipped with a fall protection mechanism, which includes a through hole and a suspension rope. The through hole is formed on the housing of the grip 300, and the suspension rope is fitted into the through hole. During use, the operator wears the suspension rope around their wrist to prevent the foldable handheld detection device from falling if released. After use, the foldable handheld detection device can be hung on a surface using the suspension rope for easy storage.

[0057] In some embodiments, continue to refer to Figure 1 The detection unit 100 includes a detection sensor 110, a camera 120, and a rotating rod 130. One end of the rotating rod 130 is rotatably connected to the support rod 200, and the detection sensor 110 is fixedly installed on the other end of the rotating rod 130. The camera 120 is fixed in the middle section of the rotating rod 130. Both the detection sensor 110 and the camera 120 are electrically connected to the display structure 310 of the grip unit 300. The camera 120 can rotate synchronously with the detection sensor 110 to achieve multi-angle measurement and shooting, and send the real-time image to the display structure 310 for display, so that the operator can know the situation in time.

[0058] In this embodiment, the specific type of the detection sensor 110 can be set according to actual needs. When thickness measurement is required, a thickness sensor is selected, and when surface flatness measurement is required, an ultrasonic sensor can be selected. In addition, the structure for realizing the multi-angle rotation of the detection sensor 110 can also be a universal ball and a universal ball seat or other structures, which are not limited here.

[0059] The above-mentioned foldable handheld detection device is used as follows:

[0060] Multiple first rods 2110 and second rods 2120 are unfolded, and the locking member 230 is moved to a first preset range and fixedly connected to the second connecting member 220. The operator puts the suspension rope on their wrist and holds the grip part 300, presses and holds the button 330, and the foldable handheld detection device is turned on. The detection sensor 110 of the control detection part 100 detects the target and sends the detection data to the display structure 310 for display. At the same time, the camera 120 sends the real-time image of the detected target object to the display structure 310 for display. When it is necessary to store the detection data, the button 330 is pressed briefly and the data is saved. The detection of other positions is performed in the same way. After the detection is completed, the button 330 is pressed and held to turn off the foldable handheld detection device. The locking member 230 is moved to a second preset position, and the first rods 2110 and second rods 2120 are flipped so that the foldable handheld detection device is bent to a length that is easy to store.

[0061] The handheld detection device with foldable function provided in this application realizes the extension and retraction of the support rod 200 through the simple structure of the connector 220 and the locking member 230. The detection unit 100 can realize multi-angle detection, and the display structure 310 on the grip unit 300 facilitates the operator's detection and recording. The above design not only ensures the safety of the operator, but also improves the support stability of the support rod 200 and improves the accuracy of the measurement results.
