Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a test apparatus for cathode stripping electrolysis reaction. Background Technology

[0002] In modern chemical research and teaching, the electrolytic reaction of cathode stripping removes the coating from the surface of a material through electrolysis, allowing for the analysis of the coating's properties. To ensure the accuracy of the experimental data, the electrolytic reaction of cathode stripping must be conducted under closed conditions; therefore, the experimental apparatus must be sealed to guarantee the accuracy of the data.

[0003] However, in the existing technology, the sealing process of the electrolytic reaction test device for cathode stripping is not only cumbersome to operate, but also requires a high level of experience and proficiency from the operators. The sealing process is time-consuming, and a lot of time needs to be spent on preparation work before each test, resulting in low test efficiency and affecting the test progress. Utility Model Content

[0004] The purpose of this application is to provide a test apparatus for cathode stripping electrolysis reaction, which aims to solve the problem of cumbersome operation during the sealing process of existing test apparatuses for cathode stripping electrolysis reaction.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a test apparatus for a cathode stripping electrolytic reaction. The test apparatus includes a base, an electrolyte supply component, and a locking component. The base has a bearing surface suitable for bearing a test specimen. The electrolyte supply component is suitable for being disposed on the side of the test specimen facing away from the base. The end of the electrolyte supply component facing the test specimen has an opening for supplying electrolyte to the test specimen through the opening. The locking component is connected between the base and the electrolyte supply component for locking the electrolyte supply component to the base and is capable of adjusting the locking distance between the electrolyte supply component and the base.

[0007] Based on the aforementioned technical means, the bearing surface of the base provides a stable foundation for the test specimen, ensuring its fixed position during the cathode stripping electrolytic reaction test, reducing the risk of seal failure due to specimen displacement, and lowering operational difficulty. The opening of the electrolyte supply component facing the test specimen allows for direct supply of electrolyte to the specimen, and the electrolyte supply component is located on the side of the test specimen facing away from the base, forming a relatively enclosed reaction space in conjunction with the base.

[0008] Meanwhile, the locking assembly connects the base and the electrolyte supply assembly, which can not only lock the two together to achieve a seal, but also adjust the locking distance between them. It can be adapted to test pieces of different thicknesses or the tightness of the seal can be adjusted according to actual needs. By setting the locking assembly between the base and the electrolyte supply assembly, the operation is simple and time-saving without relying on the operator's experience, thereby improving the efficiency of the electrolytic reaction test of cathode stripping and increasing the turnover rate of the electrolytic reaction device for cathode stripping test.

[0009] In some embodiments, the locking assembly includes an adjusting member, a first mating member, and a second mating member. The first mating member is connected to the electrolyte supply assembly, and the second mating member is connected to the base. The first and second mating members cooperate to lock the electrolyte supply assembly to the base. The adjusting member is connected to the base and mates with the second mating member. The adjusting member is used to adjust the position of the second mating member along the arrangement direction of the base and the electrolyte supply assembly to adjust the locking distance between the electrolyte supply assembly and the base; and / or, the adjusting member is connected to the electrolyte supply assembly and mates with the first mating member. The adjusting member is used to adjust the position of the first mating member along the arrangement direction of the base and the electrolyte supply assembly to adjust the locking distance between the electrolyte supply assembly and the base.

[0010] In some embodiments, the adjusting member is connected to the base, and along the arrangement direction of the base and the electrolyte supply assembly, a portion of the second mating member is located between the adjusting member and the first mating member, and the adjusting member and the second mating member are mated together to adjust the length of the portion of the second mating member.

[0011] In some embodiments, the adjusting member is threadedly engaged with the second mating member. When the second mating member rotates in the first engagement direction, the second mating member is adapted to move toward the first mating member. When the second mating member rotates in the second engagement direction, the second mating member is adapted to move away from the first mating member.

[0012] In some embodiments, the adjusting member is rotatably connected to the base. The end position of the adjusting member's rotation in the direction of rotation toward the electrolyte supply assembly is the termination position. When the adjusting member rotates to the termination position, the adjusting member is used to adjust the position of the first mating member and / or the second mating member along the arrangement direction of the base and the electrolyte supply assembly, so as to adjust the locking distance between the electrolyte supply assembly and the base.

[0013] In some embodiments, the first mating member and the second mating member are detachably connected.

[0014] In some embodiments, the first mating member is disposed on the periphery of the electrolyte supply assembly, the first mating member is provided with a fastening portion, and the second mating member is provided with a snap-fit ​​portion at one end facing the first mating member, the snap-fit ​​portion and the fastening portion being engaged and connected.

[0015] In some embodiments, the test apparatus further includes a seal adapted to connect between the electrolyte supply assembly and the test specimen. The seal has a clearance opening corresponding to the opening. The electrolyte supply assembly is used to supply electrolyte to the test specimen sequentially through the opening and the clearance opening.

[0016] In some embodiments, the electrolyte supply assembly includes a container and a cover plate. The container is adapted to be disposed on the side of the test piece away from the base. The container has an opening. The cover plate is connected to the side of the container away from the test piece. A locking assembly is connected between the cover plate and the electrolyte supply assembly.

[0017] In some embodiments, the cover plate is provided with at least one electrode hole, which communicates with the inner cavity of the accommodating cylinder. Attached Figure Description

[0033] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0034] The cathodic stripping electrolytic reaction test is a test method used to evaluate the resistance of coatings or anti-corrosion layers to stripping under cathodic protection. During the test, the electrochemical reaction that occurs at the coating defects under the combined action of cathodic protection and corrosive environment (including electrolyte) is simulated, which leads to the process of the coating peeling off from the metal substrate.

[0035] In some embodiments, see Figure 1 This application provides a test apparatus for cathode stripping electrolysis reaction, used for cathode stripping tests.

[0036] Of course, the experimental apparatus for cathode stripping electrolysis in this application can also be used for other electrolysis reactions (such as electrolytic refining of metals). This application does not limit this application, but only uses the experimental apparatus for cathode stripping electrolysis as an example.

[0037] In some embodiments, see Figure 1 and combined Figure 4 The test apparatus in this application includes a base 200, which has a bearing surface 201 adapted to bear the test piece 500 so that the test piece 500 can stably carry out the electrolytic reaction of cathode stripping.

[0038] It should be noted that when the test apparatus for the cathode stripping electrolysis reaction in this application can be used for cathode stripping tests, the test piece 500 in this application can be a metallic part. Of course, when the test apparatus is used for other purposes, the test piece 500 can also be a non-metallic part, and this application does not specifically limit this.

[0039] In some embodiments, see Figure 1 The test apparatus of this application includes an electrolyte supply assembly 100. The electrolyte supply assembly 100 is adapted to be disposed on the side of the test piece 500 facing away from the base 200. An opening is provided at the end of the electrolyte supply assembly 100 facing the test piece 500. Figure 1 The opening is not shown due to obstruction. Specifically, the opening can be located on the lower end face of the accommodating cylinder 102 described below. The electrolyte supply assembly 100 is used to supply electrolyte to the test piece 500 through the opening. It can be understood that the surface of the test piece 500 that is in contact with the electrolyte is the surface to be tested.

[0040] For example, the test piece 500 is directly attached to the wall surface around the opening. At this time, the wall surface around the opening and the test piece 500 form a closed receiving space. After the electrolyte enters the space through the opening, it can be concentrated on the surface of the test piece 500 opposite to the opening, thus preventing the electrolyte from flowing randomly.

[0041] In another example, the opening is connected to a pipe that connects the test surface to the opening. After the electrolyte enters the pipe through the opening, it is directionally delivered to the surface of the test piece 500 facing the opening through the pipe.

[0042] Of course, the operator may also adjust the connection between the test piece 500 and the electrolyte supply assembly 100 to other relationships. This application does not limit this, and this application uses the example of the test piece 500 being directly attached to the wall surface around the opening as an example for illustration.

[0043] In some embodiments, see Figure 1 The test apparatus in this application also includes a locking component 300, which is connected between the base 200 and the electrolyte supply component 100. The locking component 300 is used to lock the electrolyte supply component 100 to the base 200 and can adjust the locking distance between the electrolyte supply component 100 and the base 200.

[0044] By way of example, the locking assembly 300 is adapted to provide a rigid locking force to the electrolyte supply assembly 100 and the base 200. By yet another example, the locking assembly 300 is adapted to provide a resilient locking force to the electrolyte supply assembly 100 and the base 200. This application does not limit the scope of the application in this regard.

[0045] Based on this, the locking component 300 in this application is connected between the base 200 and the electrolyte supply component 100. The locking component 300 can lock the electrolyte supply component 100 to the base 200 so that the wall surface around the opening can be stably attached to the test piece 500, avoiding electrolyte leakage or reaction interruption due to loose connection between the two, thus enhancing the sealing and stability of the device.

[0046] Meanwhile, the locking component 300 can adjust the locking distance between the electrolyte supply component 100 and the base 200, and can be adapted to test pieces 500 of different thicknesses. It does not require the replacement of components of a specific size, which improves the versatility and flexibility of the device and makes operation more convenient.

[0047] In some embodiments, see Figure 1 and combined Figure 4 In this application, the surface of the test piece 500 facing the opening of the electrolyte supply assembly 100 and the surface facing the bearing surface 201 can both be flat, so that the test piece 500 can form a tightly fitting sealing surface with the bearing surface 201, the opening of the electrolyte supply assembly 100, etc.

[0048] In some embodiments, see Figure 1 and combined Figure 2 The test apparatus in this application also includes a seal 400, which is adapted to be connected between the electrolyte supply assembly 100 and the test piece 500. The seal 400 is provided with a clearance opening 401, which corresponds to the opening. The electrolyte supply assembly 100 is used to supply electrolyte to the test piece 500 in sequence through the opening and the clearance opening 401.

[0049] The seal 400 is connected between the electrolyte supply assembly 100 and the test piece 500, and its clearance port 401 corresponds to the opening to ensure that the electrolyte can flow to the test piece 500 in sequence through the opening and clearance port 401.

[0050] Under the locking force provided by the locking assembly 300, the seal 400 is tightly pressed between the two, which can fill any tiny gaps that may exist on the contact surface, enhance the overall sealing performance of the device, and reduce the risk of electrolyte leakage and gas leakage. At the same time, the stable and controllable locking force ensures that the seal 400 is subjected to uniform force, avoiding the sealing effect due to insufficient local pressure, and also preventing damage to the seal 400 due to excessive pressure, thus extending its service life and further improving the reliability of the test device.

[0051] In some embodiments, see Figure 1 and combined Figure 2 The seal 400 is an elastic seal 400.

[0052] With the rigid locking force provided by the locking component 300, the elastic seal 400 can fit more tightly against the surfaces of the electrolyte supply component 100 and the test piece 500 when under pressure, adaptively filling the small unevenness or gaps on the contact surface, further improving the sealing effect and reducing the possibility of electrolyte leakage and gas leakage.

[0053] Meanwhile, the elastic seal 400 can buffer the rigid force applied by the locking assembly 300, avoiding damage to the test piece 500 or the electrolyte supply assembly 100 due to excessive locking force, and can maintain a stable sealing state even when there are slight fluctuations in the locking force, thus enhancing the practicality and safety of the device.

[0054] For example, the seal 400 is a sealing gasket with a square outer frame and a circular hole in the middle. The circular hole forms a clearance opening 401, and the diameter of the circular hole is smaller than the diameter of the receiving cylinder 102. During the test, it is placed directly above the test surface of the test piece 500.

[0055] As another example, the seal 400 is made of a corrosion-resistant, highly elastic rubber material.

[0056] In some embodiments, for ease of understanding, this application provides an exemplary description of one possible structure of the electrolyte supply assembly 100, but this does not constitute a limitation of this application.

[0057] Please see Figure 1 The electrolyte supply assembly 100 includes a container 102 and a cover plate 101. The container 102 is adapted to be disposed on the side of the test piece 500 opposite to the base 200. The container 102 has the opening described above for connecting with the test piece 500. The cover plate 101 is connected to the side of the container 102 opposite to the test piece 500. The locking assembly 300 is connected between the cover plate 101 and the base 200.

[0058] The opening of the container 102 faces the test piece 500, and the periphery of the opening can contact the elastic seal 400. The cover plate 101 closes the side of the container 102 away from the test piece 500, so that the interior of the container 102 forms a space for containing electrolyte. The cover plate 101 is locked to the base 200 by the locking assembly 300. Under the action of the locking force, the container 102 moves closer to the test piece 500, causing the elastic seal 400 to fit tightly against the periphery of the opening of the container 102 and the surface of the test piece 500.

[0059] The elastic seal 400 is tightly pressed together by the locking force of the locking assembly 300, which can fully fill the gap between the periphery of the opening of the accommodating cylinder 102 and the surface of the test piece 500, preventing electrolyte leakage and allowing the electrolyte to concentrate on the test area of ​​the test piece 500.

[0060] For example, the accommodating cylinder 102 and the cover plate 101 are integrally formed.

[0061] In another example, the accommodating cylinder 102 and the cover plate 101 are respectively formed and assembled together.

[0062] Correspondingly, the seal 400 is connected between the accommodating cylinder 102 and the test piece 500 to seal the gap between the accommodating cylinder 102 and the test piece 500.

[0063] In this application, the accommodating cylinder 102 is connected to the cover plate 101 as an example.

[0064] It should be noted that this application does not limit the material of the container 102. For example, the container 102 can be made of plastic to reduce costs. As another example, the container 102 can also be a transparent cylinder to facilitate observation of the electrolytic reaction during cathode stripping by the operator. It should be noted that transparent materials include, but are not limited to, acrylic and glass.

[0065] In some embodiments, see Figure 1 The accommodating cylinder 102 is a hollow cylinder surrounded by a surrounding plate. One end of the hollow cylinder is attached to the test piece 500, and the other end of the hollow cylinder is connected to the cover plate 101. The surface of the cover plate 101 facing the accommodating cylinder 102 has a protrusion with a diameter slightly smaller than that of the accommodating cylinder 102, so as to ensure that the center of the cover plate 101 is directly opposite the opening at the other end of the hollow cylinder for connection with the cover plate 101.

[0066] In some embodiments, see Figure 1 The cover plate 101 is provided with at least one electrode hole, which is connected to the inner cavity of the accommodating cylinder 102.

[0067] The electrode can be inserted through the electrode hole into the inner cavity of the container 102 and come into contact with the electrolyte in the container 102 so that the electrolyte can undergo a cathode stripping electrolytic reaction with the test surface of the test piece 500.

[0068] The electrode holes facilitate electrode insertion without requiring complex modifications to the container 102 or cover 101, resulting in a simple and easily implemented structure. The electrode extends into the electrolyte through the electrode holes, maintaining a stable position and ensuring reliable contact with the electrolyte, thus guaranteeing stable current during the cathode stripping electrolysis reaction. Simultaneously, the electrode holes do not affect the sealing effect of the cover 101 on the container 102; in conjunction with the locking assembly 300 and the sealing element 400, good sealing of the device is still maintained.

[0069] For example, please see Figure 1 and combined Figure 5The cover plate 101 has an auxiliary electrode hole 1011 and a reference electrode hole 1012 for placing the auxiliary electrode and the reference electrode. The reference electrode hole 1012 is also used to inject electrolyte into the container cylinder 102.

[0070] In some embodiments, see Figure 1 and combined Figure 5 The auxiliary electrode hole 1011 and the reference electrode hole 1012 are stepped holes (small at the bottom and large at the top) to ensure the stability of the auxiliary electrode and the reference electrode during the test.

[0071] In some embodiments, see Figure 1 The circumferential wall of the accommodating cylinder 102 is provided with a hanging ear 1021, which is used to facilitate hand holding during the movement of the entire test device.

[0072] This application provides further illustrative examples of embodiments of the locking assembly 300, which is adapted to provide a rigid locking force to the electrolyte supply assembly 100 and the base 200. This does not constitute a limitation of the application; other structures capable of providing a locking force to the electrolyte supply assembly 100 and the base 200 are also within the scope of protection of this application.

[0073] In some embodiments, see Figure 1 and combined Figure 3 The locking assembly 300 includes an adjusting member 303, a first mating member 301, and a second mating member 302. The first mating member 301 is connected to the electrolyte supply assembly 100, and the second mating member 302 is connected to the base 200. The first mating member 301 and the second mating member 302 cooperate to lock the electrolyte supply assembly 100 to the base 200.

[0074] In one possible implementation of this embodiment, the adjusting member 303 is connected to the base 200 and is connected to the second mating member 302. The adjusting member 303 is used to adjust the position of the second mating member 302 along the arrangement direction of the base 200 and the electrolyte supply assembly 100, so as to adjust the locking distance between the electrolyte supply assembly 100 and the base 200.

[0075] Thus, the first mating component 301 is connected to the electrolyte supply assembly 100, and the second mating component 302 is connected to the base 200, and the two cooperate to lock the electrolyte supply assembly 100 to the base 200. The adjusting component 303 is connected to the base 200 and cooperates with the second mating component 302. When it is necessary to adjust the locking distance between the electrolyte supply assembly 100 and the base 200, by operating the adjusting component 303, the second mating component 302 can be moved along the arrangement direction of the base 200 and the electrolyte supply assembly 100, thereby changing the mating position of the first mating component 301 and the second mating component 302, and realizing the adjustment of the locking distance.

[0076] The adjusting component 303 acts directly on the second mating component 302 connected to the base 200, making the adjustment process more stable, accurately controlling the change of the locking gap, and ensuring reliable operation when adapting to test pieces 500 of different thicknesses, and also helping to ensure the stability of the locking state.

[0077] In another possible implementation of this embodiment, the adjusting member 303 is connected to the electrolyte supply assembly 100, and the adjusting member 303 is connected to the first mating member 301. The adjusting member 303 is used to adjust the position of the first mating member 301 along the arrangement direction of the base 200 and the electrolyte supply assembly 100, so as to adjust the locking distance between the electrolyte supply assembly 100 and the base 200.

[0078] Therefore, the first mating part 301 is connected to the electrolyte supply assembly 100, and the second mating part 302 is connected to the base 200, and the two cooperate to achieve locking. The adjusting part 303 is connected to the electrolyte supply assembly 100 and is mated with the first mating part 301. During adjustment, operating the adjusting part 303 can drive the first mating part 301 to move along the arrangement direction of the base 200 and the electrolyte supply assembly 100, thereby changing the mating position of the first mating part 301 and the second mating part 302, and achieving the purpose of adjusting the locking gap.

[0079] The adjusting component 303 acts on the first mating component 301 connected to the electrolyte supply component 100, which can more directly adjust the position of the electrolyte supply component 100. When the spacing needs to be frequently adjusted to adapt to different test requirements, the operation is more convenient and efficient.

[0080] Both implementation methods in this embodiment achieve the adjustment of the locking distance through the cooperation of the adjusting component 303, the first mating component 301, and the second mating component 302. The structure is simple, easy to operate, and can effectively adapt to test pieces 500 of different thicknesses, thus improving the versatility and practicality of the test device.

[0081] In some embodiments, see Figure 1 and combined Figure 3The adjusting member 303 is connected to the base 200. Along the arrangement direction of the base 200 and the electrolyte supply assembly 100, a portion of the second mating member 302 is located between the adjusting member 303 and the first mating member 301. The adjusting member 303 and the second mating member 302 are connected to adjust the length of a portion of the second mating member 302.

[0082] Adjustment member 303 is connected to base 200. Along the arrangement direction of base 200 and electrolyte supply assembly 100, part of second mating member 302 is located between adjustment member 303 and first mating member 301. First mating member 301 is connected to electrolyte supply assembly 100. Second mating member 302 and first mating member 301 cooperate to achieve locking.

[0083] When the locking gap needs to be adjusted, the adjusting member 303 is operated to engage with the second mating member 302, thereby changing the length of the portion of the second mating member 302 located between the adjusting member 303 and the first mating member 301. As the length of this portion changes, the mating position of the first mating member 301 and the second mating member 302 changes accordingly, ultimately achieving the adjustment of the locking gap between the electrolyte supply assembly 100 and the base 200.

[0084] The adjustment of the length of the second mating part 302 is directly related to the locking gap. The adjustment method is intuitive and precise, and can be adapted to test pieces 500 of different thicknesses. At the same time, the layout of the adjusting part 303 connecting to the base 200 and the second mating part 302 located between the two makes the force transmission more stable, reduces shaking during the adjustment process, ensures the reliability of the locking state, and the overall structure is simple and easy to operate.

[0085] In some embodiments, see Figure 1 and combined Figure 3 The adjusting member 303 is threadedly engaged with the second mating member 302. When the second mating member 302 rotates in the first engagement direction, the second mating member 302 is adapted to move toward the first mating member 301. When the second mating member 302 rotates in the second engagement direction, the second mating member 302 is adapted to move away from the first mating member 301.

[0086] For example, please see Figure 1 and combined Figure 3 and Figure 6 The adjusting member 303 is provided with a threaded hole 3031 for threaded connection with the second mating member 302.

[0087] Adjustment component 303 is connected to base 200. Along the arrangement direction of base 200 and electrolyte supply assembly 100, part of second mating component 302 is located between adjustment component 303 and first mating component 301. First mating component 301 is connected to electrolyte supply assembly 100. Adjustment component 303 and second mating component 302 are connected by threaded engagement.

[0088] When the locking gap increases, if the second mating part 302 is rotated along the first engagement direction (such as clockwise), the second mating part 302 will move toward the first mating part 301 under the transmission action of the thread. At this time, the length of the part of the second mating part 302 located between the adjusting part 303 and the first mating part 301 increases, thereby enabling the second mating part 302 to connect with the first mating part 301.

[0089] When the locking gap decreases, the second mating part 302 is rotated along the second engagement direction (such as counterclockwise), and the length of this part is shortened, thereby enabling the second mating part 302 to connect with the first mating part 301.

[0090] The threaded connection between the adjusting member 303 and the second mating member 302 has self-locking properties. After adjustment, the position of the second mating member 302 can be stably maintained, avoiding changes in the locking distance due to vibration and other factors, thus ensuring the stability of the device. By rotating the second mating member 302, the length of the part located between the adjusting member 303 and the first mating member 301 can be precisely adjusted, thereby achieving fine adjustment of the locking distance. The operation is simple and the adjustment accuracy is high.

[0091] In some embodiments, see Figure 1 and combined Figure 3 The locking assembly 300 in this application also includes a locking nut 305, which is threadedly connected to the second mating member 302. When adjusted to the position, the locking nut 305 rotates to contact the adjusting member 303, so that the second mating member 302 is further fixed relative to the adjusting member 303.

[0092] The adjusting member 303 is threadedly connected to the second mating member 302, and the locking nut 305 is also threadedly connected to the second mating member 302. When adjusting the locking gap, first rotate the second mating member 302, moving it along the first or second mating direction until the desired position is reached. Then, rotate the locking nut 305, moving it along the thread of the second mating member 302 toward the adjusting member 303, until the locking nut 305 and the adjusting member 303 are in tight contact. The friction between the locking nut 305 and the adjusting member 303 restricts the rotation of the second mating member 302 relative to the adjusting member 303, thereby further fixing the second mating member 302 in the adjusted position.

[0093] In some embodiments, see Figure 1 and combined Figure 3The adjusting member 303 is rotatably connected to the base 200. The adjusting member 303 rotates in the direction of rotation toward the electrolyte supply assembly 100. The end position of the adjusting member 303 is the termination position. When the adjusting member 303 rotates to the termination position, the adjusting member 303 is used to adjust the position of the first mating member 301 and / or the second mating member 302 along the arrangement direction of the base 200 and the electrolyte supply assembly 100, so as to adjust the locking distance between the electrolyte supply assembly 100 and the base 200.

[0094] The adjusting member 303 is rotatably connected to the base 200. The final position of the adjusting member 303 as it rotates towards the electrolyte supply assembly 100 is the termination position. The first mating member 301 is connected to the electrolyte supply assembly 100, and the second mating member 302 is connected to the base 200; the two cooperate to achieve locking. When it is necessary to adjust the locking gap, the adjusting member 303 is rotated towards the electrolyte supply assembly 100 until it reaches the termination position. During this process, the adjusting member 303 exerts a force on the first mating member 301 and / or the second mating member 302, causing them to change position along the arrangement direction of the base 200 and the electrolyte supply assembly 100, thereby changing the locking gap between the electrolyte supply assembly 100 and the base 200.

[0095] When it is necessary to lock the base 200 and the electrolyte supply assembly 100, the adjusting member 303 rotates away from the electrolyte supply assembly 100 to release the locking of the first mating member 301 and the second mating member 302.

[0096] In some embodiments, see Figure 1 and combined Figure 3 and Figure 4 The base 200 is provided with a support frame 304, which is rotatably connected to the adjusting component 303.

[0097] For example, the support frame 304 is bolted to the body of the base 200. The support frame 304 is located on the periphery of the body.

[0098] In some embodiments, see Figure 1 and combined Figure 3 and Figure 4 The base 200 includes a main body and multiple support frames 304, including a first support frame and a second support frame. The first support frame is connected to the main body, and the second support frame is rotatably connected to the adjusting member 303. The first support frame and the second support frame are detachably connected to achieve the detachability of the locking component relative to the base 200.

[0099] Another example is that the body is made of PVC plastic sheet with a thickness of 10mm.

[0100] The support frame 304 on the base 200 provides a stable rotation support point for the adjustment component 303, making the rotation of the adjustment component 303 smoother, reducing the shaking during the rotation process, and ensuring the reliability of the adjustment operation.

[0101] In some embodiments, see Figure 1 The first mating part 301 and the second mating part 302 are detachably connected.

[0102] For example, the first mating member 301 and the second mating member 302 are connected by a snap-fit.

[0103] Another example is that the first mating part 301 and the second mating part 302 are connected by bolts.

[0104] When it is necessary to install the test piece 500, the first mating part 301 and the second mating part 302 can be separated, the test piece 500 can be placed on the base 200 and its position adjusted, and then the two can be connected and fixed. If it is necessary to replace the test piece 500 of different specifications or to maintain the device, the connection between the first mating part 301 and the second mating part 302 can be directly disassembled. The operation does not require disassembly of other parts such as the support frame 304 and the adjusting part 303, which simplifies the installation and replacement process of the test piece 500 and the maintenance of the device.

[0105] In some embodiments, see Figure 1 The first mating part 301 is disposed on the periphery of the electrolyte supply assembly 100. The first mating part 301 is provided with a fastening part 3011. The second mating part 302 is provided with a snap-fit ​​part 3021 at one end facing the first mating part 301. The snap-fit ​​part 3021 is engaged and connected with the fastening part 3011.

[0106] When installing the test piece 500, align the electrolyte supply assembly 100 with the test piece 500 on the base 200, and rotate the adjustment component 303 to the end position in conjunction with the rotatable connection between the adjustment component 303 and the support frame 304. Further adjust the distance between the first mating component 301 and the second mating component 302, and then engage the fastening part 3011 and the snap-fit ​​part 3021 to fix the first mating component 301 and the second mating component 302.

[0107] For example, the second mating part 302 is a screw, and the circumference of the screw is provided with a thread that mates with the adjusting part 303. The end of the screw facing the first mating part 301 is provided with a snap-fit ​​part 3021.

[0108] In another example, the first mating member 301 is provided with a hook forming a fastening portion 3011, and the snap-fit ​​portion 3021 is an annular member with a through hole, the through hole being engaged with the hook.

[0109] The shape of the ring-shaped component can be either an inverted triangle or a circle; this application does not limit the shape of the ring.

[0110] In some embodiments, see Figure 1 The number of locking components 300 is multiple, and the multiple locking components 300 are spaced apart around the electrolyte supply component 100.

[0111] Based on the above, this application also provides a test method for a sealing device used in the aforementioned cathode stripping electrolysis reaction. Please refer to [link to relevant documentation]. Figures 1-6 The method includes:

[0112] S101. Place the test piece 500 on the base 200.

[0113] S102. Place the seal 400 directly above the test piece 500, and place the container 102 directly above the seal 400.

[0114] S103. Place the receiving cylinder 102 and the cover plate 101 above the sealing element 400.

[0115] S104. Rotate the second mating part 302 so that it moves relative to the adjusting part 303. By adjusting the height of the second mating part 302, the accommodating cylinder 102, the sealing part 400 and the test piece 500 are properly sealed when the upper end of the second mating part 302 is engaged with the first mating part 301.

[0116] Of course, the adjusting part 303 and the second mating part 302 can be adjusted first, so that the second mating part 302 is lower than the height of the accommodating cylinder 102, and the second mating part 302 can be further adjusted after the cover plate 101 is installed.

[0117] S105. Pour the electrolyte into the container 102 through the reference electrode hole 1012.

[0118] S106. Place the auxiliary electrode and reference electrode into the container 102 through the auxiliary electrode hole 1011 and the reference electrode hole 1012, place the test device in the constant temperature heating equipment, and turn on the power.

[0119] S107. After the test, remove the auxiliary electrode and the reference electrode, and pour out the electrolyte from the reference electrode hole 1012.

[0120] S108. Release the lock between the first mating part 301 and the second mating part 302, and take out the cover plate 101, the accommodating cylinder 102, the sealing part 400 and the test piece 500 in sequence.

[0121] In this step, the adjusting component 303 can first rotate away from the electrolyte supply component 100, and then the cover plate 101, the container 102, the seal 400 and the test piece 500 can be taken out in sequence to avoid the adjusting component 303 affecting the disassembly of the test device.

[0122] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
