[0004] To address this, the present invention provides a portable electrophoretic coating adhesion tester, which enables rapid and stable replacement of test probe sleeves of different specifications through an efficient positioning and replacement mechanism, without the need for special tools, thereby improving adaptability and efficiency; at the same time, the overall structure is optimized and relevant components are added to enhance portability and operational comfort, ensuring stable and accurate testing and meeting diverse testing needs. Utility Model Content

[0005] The purpose of this invention is to provide a portable electrophoretic coating adhesion tester, which aims to solve the problems of existing testers with replaceable probes, which have complex replacement structures, are cumbersome to operate, often require special tools to complete the replacement, and have poor connection stability between the probe and the main body after replacement, which is prone to loosening during the testing process and affects the accuracy of the test data.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable electrophoretic coating adhesion tester, comprising:

[0008] The detection body has a fixed sleeve fixedly connected to one end, a detection probe sleeve is provided inside the fixed sleeve, and three limiting ports are opened at one end of the fixed sleeve. A first limiting groove is opened on the rear inner wall of the three limiting ports, and a convex hole is opened on the rear inner wall of the first limiting groove.

[0009] A positioning and replacement mechanism is provided inside a fixed sleeve, and the positioning and replacement mechanism is used to replace the sleeves of detection probes of different specifications.

[0010] As a preferred embodiment of this utility model, the positioning and changing mechanism includes:

[0011] Three insert blocks, all three of which are fixedly connected to the circumferential surface of the detection probe sleeve;

[0012] Three slots, each of which is located at one end of one of the three inserts;

[0013] Three second limiting grooves are provided, each of which is located on the front inner wall of the first limiting groove. Each of the three second limiting grooves has a limiting hole on its rear inner wall. Each of the three limiting holes has a limiting rod slidably connected to it. One end of each of the three limiting rods is fixedly connected to a locking block. Each of the three locking blocks is movably engaged in the three insert blocks.

[0014] Three second springs, one end of each of the three second springs is fixedly connected to the rear inner wall of the three second limiting grooves, the three second springs are respectively sleeved on the outer surface of the three limiting rods, and the other end of each of the three second springs is fixedly connected to one end of the locking block.

[0015] As a preferred embodiment of this utility model, a first spring is fixedly connected to the rear inner wall of the convex hole, and a support slide is fixedly connected to one end of the first spring. The support slide is close to the electrical interface of the detection probe sleeve.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-5 The present invention provides the following technical solution:

[0033] A portable electrophoretic coating adhesion tester, comprising:

[0034] The detection body 1 has a fixed sleeve 4 fixedly connected to one end. The fixed sleeve 4 is equipped with a detection probe sleeve 5. One end of the fixed sleeve 4 has three limiting ports 10. The inner rear wall of the three limiting ports 10 has a first limiting groove 9. The inner rear wall of the first limiting groove 9 has a convex hole 8.

[0035] The positioning and replacement mechanism is located inside the fixed sleeve 4 and is used to replace the sleeves 5 of different specifications of the detection probes.

[0036] In a specific embodiment of this utility model, the detection body 1 is the core load-bearing component of the entire testing instrument, providing an installation foundation and structural support for other parts. Its interior can accommodate key functional components such as the data processing module and power supply module, ensuring that each component maintains a relatively stable positional relationship during operation and guaranteeing the overall coordination of the testing instrument's operation. Simultaneously, the structural design of the detection body 1 directly affects the portability of the testing instrument. The detection body 1, made of lightweight, high-strength materials, reduces the overall weight while maintaining structural strength, making it easier for operators to carry and use.

[0037] The fixing sleeve 4 is fixedly connected to one end of the detection body 1, mainly serving the functions of connection and positioning. It provides installation space for the detection probe sleeve 5, enabling the detection probe sleeve 5 to stably form a connection with the detection body 1, ensuring that the detection probe sleeve 5 will not shake or shift during the detection process, thereby guaranteeing the accuracy of the detection. Furthermore, the limiting port 10, the first limiting groove 9, and the convex hole 8 on the fixing sleeve 4 provide the necessary structural foundation for the operation of the positioning and replacement mechanism, and are one of the key components for achieving rapid replacement and accurate positioning of the detection probe sleeve 5.

[0038] The probe sleeve 5 is the component for mounting the probe. Different specifications of probe sleeves 5 can be adapted to different types and sizes of probes to meet the testing needs of electrophoretic coating films of different thicknesses and materials. It is installed inside the fixing sleeve 4 and, in conjunction with the positioning and changing mechanism, enables quick installation and replacement, ensuring that the appropriate probe can be switched promptly when testing different workpieces, thus improving the flexibility and adaptability of the testing process.

[0039] Three limiting ports 10 are located at one end of the fixed sleeve 4, evenly distributed around its circumference. Their main function is to provide guidance and initial positioning for the limiting components in the positioning and replacement mechanism. When installing or replacing the detection probe sleeve 5, the relevant components of the positioning and replacement mechanism can enter the fixed sleeve 4 through the limiting ports 10, achieving initial positioning of the detection probe sleeve 5, preventing circumferential rotation during installation, and ensuring the accuracy of subsequent positioning.

[0040] The first limiting groove 9 is formed on the rear inner wall of the limiting port 10 and communicates with the limiting port 10. Its function is to further limit and fix the limiting component in the positioning and changing mechanism. When the component of the positioning and changing mechanism passes through the limiting port 10, it will enter the first limiting groove 9. The shape of the first limiting groove 9 matches the limiting component and can limit the axial movement of the limiting component, thereby stably fixing the detection probe sleeve 5 in the fixing sleeve 4, preventing axial displacement of the detection probe sleeve 5 during the detection process, and ensuring the normal operation of the detection work.

[0041] A convex hole 8 is formed on the inner rear end of the first limiting groove 9. Its special convex structure is mainly used to cooperate with the elastic component in the positioning and replacement mechanism. When the positioning and replacement mechanism is working, the elastic component can extend and retract within the convex hole 8. When the detection probe sleeve 5 needs to be replaced, the extension and retraction of the elastic component within the convex hole 8 can drive the limiting component of the positioning and replacement mechanism to exit from the first limiting groove 9, releasing the fixation of the detection probe sleeve 5. After the detection probe sleeve 5 is installed, the elastic component resets within the convex hole 8, pushing the limiting component into the first limiting groove 9, thus re-fixing the detection probe sleeve 5. The design of the convex hole 8 provides suitable movement space for the elastic component, ensuring that the positioning and replacement mechanism can operate flexibly and reliably.

[0042] It should be noted that the specific type of detection probe sleeve 5 and detection body 1 used shall be selected by those skilled in the art, and the above-mentioned detection probe sleeve 5 and detection body 1 are all existing technologies, which will not be elaborated in this solution.

[0043] Please refer to the details. Figures 1-5 The positioning and replacement mechanism includes:

[0044] Three insert blocks 13 are fixedly connected to the circumferential surface of the detection probe sleeve 5;

[0045] Three slots 14, each of which is located at one end of one of the three insert blocks 13;

[0046] Three second limiting grooves 12 are provided on the front inner wall of the first limiting groove 9. Each of the three second limiting grooves 12 has a limiting hole on its rear inner wall. Each of the three limiting holes is slidably connected to a limiting rod 15. One end of each of the three limiting rods 15 is fixedly connected to a locking block 3. Each of the three locking blocks 3 is movably locked into the three insert blocks 13.

[0047] Three second springs 16, one end of each of the three second springs 16 is fixedly connected to the rear inner wall of the three second limiting grooves 12, the three second springs 16 are respectively sleeved on the outer surface of the three limiting rods 15, and the other end of each of the three second springs 16 is fixedly connected to one end of the locking block 3.

[0048] In this embodiment: the operator aligns the three inserts 13 of the detection probe sleeve 5 with the three limiting ports 10 of the fixed sleeve 4 and pushes them into the fixed sleeve 4 axially. At this time, the ends of the inserts 13 contact the wedge-shaped surfaces of the locking blocks 3 and generate pressure. Under the action of the thrust, the locking blocks 3 move into the second limiting groove 12, while simultaneously driving the limiting rod 15 to slide backward along the limiting hole. The second spring 16 is further compressed and stores elastic potential energy.

[0049] When the insert 13 is fully inserted into the first limiting groove 9, the slot 14 on the insert 13 is precisely aligned with the position of the locking block 3. At this time, the elastic force of the second spring 16 is released, pushing the locking block 3 forward. The head of the locking block 3 is precisely locked into the slot 14, and the limiting rod 15 returns to its original position as the locking block 3 moves forward. Thus, the insert 13 is axially locked, and the detection probe sleeve 5 and the fixing sleeve 4 form a rigid connection, completing the installation.

[0050] Please refer to the details. Figures 1-3 A first spring 7 is fixedly connected to the inner rear wall of the convex hole 8. A support slide plate 6 is fixedly connected to one end of the first spring 7. The support slide plate 6 is close to the electrical interface of the detection probe sleeve 5.

[0051] In this embodiment: the convex hole 8 provides installation space for the first spring 7 and the support slide plate 6. One end of the first spring 7 is fixed to the inner wall of the rear of the convex hole 8, and the other end is connected to the support slide plate 6. When the detection probe sleeve 5 is installed in place, the support slide plate 6 is pressed against the electrical interface of the detection probe sleeve 5 under the elastic force of the first spring 7. This ensures a stable electrical connection between the detection probe sleeve 5 and the internal circuit of the detection body 1, and also reduces the impact of vibration on the interface connection during the detection process through the buffering effect of the spring. At the same time, when replacing the detection probe sleeve 5, the first spring 7 pushes the support slide plate 6 to help it pop out, making it easy to remove.

[0052] Please refer to the details. Figure 2 A hand handle 102 is fixedly connected to the bottom of the detection body 1, and a smart display screen 101 is fixedly connected to one end of the detection body 1.

[0053] In this embodiment: the handle 102 is fixed to the bottom of the detection body 1, conforming to an ergonomic design, allowing the operator to stably control the detection body 1 while holding it, ensuring that the detection probe is aligned with the detection area. The intelligent display screen 101 is fixed to one end of the detection body 1 and electrically connected to the internal data processing module. During the detection process, the data processing module transmits the analyzed adhesion data to the intelligent display screen 101. When the operator holds the handle 102, they can intuitively read the detection results, operation prompts, and other information on the display screen, achieving synchronous and convenient operation and reading.

[0054] Please refer to the details. Figures 1-5The top of the detection body 1 has a hook hole 103, and the circumferential surfaces of the three limit rods 15 are fixedly connected with pull rings 11.

[0055] In this embodiment, the hook hole 103 is located at the top of the detection body 1, and can be used with hooks, ropes, and other components to achieve portable suspension of the tester, making it easy to carry and store. Three pull rings 11 are fixed to the circumferential surface of the limiting rods 15 and correspond one-to-one with the three limiting rods 15. When it is necessary to replace the detection probe sleeve 5, the operator can pull the limiting rods 15 simultaneously or separately through the pull rings 11 to drive the locking block 3 out of the slot 14.

[0056] Please refer to the details. Figures 1-3 The bottom end of the hand handle 102 is fixedly connected to a support base 2, and the outer surface of the support base 2 is fixedly connected to an edge sleeve 201.

[0057] In this embodiment: the support base 2 is fixed to the bottom of the handle 102. When the tester is not in use, the support base 2 allows the tester to be placed stably on a flat surface such as a table, avoiding damage to the detection probe from collision with the contact surface, while maintaining the stable posture of the handle 102 and the detection body 1. The edge sleeve 201 is fixed to the outer surface of the support base 2 and is made of anti-slip and wear-resistant material. This not only enhances the friction between the support base 2 and the placement surface to prevent slippage, but also protects the edge of the support base 2, reducing wear during collisions and extending its service life.

[0058] The working principle and usage process of this utility model are as follows: To solve the problem of cumbersome replacement of detection probes and the need for special tools, the operator holds the handle 102 and pulls the limiting rod 15 backward through the pull ring 11 with the other hand. The limiting rod 15 slides along the limiting hole and drives the locking block 3 to exit from the slot 14 of the insert block 13. At the same time, the second spring 16 is compressed. At this time, the first spring 7 in the convex hole 8 pushes the support slide plate 6 to push the detection probe sleeve 5 forward, so that the old detection probe sleeve 5 can be directly removed. When installing the new detection probe sleeve 5, its insert block 13 is aligned with the limiting port 10 of the fixing sleeve 4 and pushed in. The insert block 13 squeezes the locking block 3 to retract and compress the second spring 16. When the insert block 13 is fully inserted into the first limiting groove 9, the slot 14 is aligned with the locking block 3, and the second spring 16 resets and pushes the locking block 3 into the slot 14 to complete the locking. To address the issue of unstable connection between the probe and the main body, after installation, the support slide plate 6, under the action of the first spring 7, adheres to the electrical interface to ensure circuit connection. The locking block 3 and the slot 14 are rigidly engaged, cooperating with the first limiting groove 9 to constrain the insertion block 13. The operator can reduce equipment shaking by holding the anti-slip handle 102. To address the issues of insufficient portability and inconvenient storage, the device is carried during testing via the handle 102, and the intelligent display screen 101 displays data in real time. After testing, the support base 2 can be placed on a flat surface with anti-slip edge sleeves 201, or it can be suspended or carried via the hook hole 103 with a hanging rope.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
