Description

Technical Field

[0001] This utility model relates to the field of electrode clamp technology, specifically an electrode impedance testing clamp. Background Technology

[0002] Electrode impedance testing is an important means of evaluating the electrical performance of electrodes. It is mainly used to measure the resistance characteristics of electrodes when current passes through them. The test results are of key significance for electrode quality assessment and performance optimization. In the process of electrode impedance testing, electrode fixtures are an indispensable tool, and their performance directly affects the accuracy and efficiency of the test.

[0003] Existing electrode clamps are difficult to hold electrodes of different thicknesses stably. This requires frequent clamp changes or complex adjustments when testing electrodes of different specifications. This not only increases the workload of staff, but may also lead to inaccurate test results due to unstable clamping. Therefore, improvements are needed. Utility Model Content

[0009] Preferably, the limiting block is disposed at the bottom of the nut, and the inner side of the limiting block is in contact with the outer side of the nut. The limiting block can limit the nut, making it difficult for the nut to rotate when the bolt rotates.

[0014] Beneficial effects:

[0015] 1.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-5 This utility model provides a technical solution: an electrode impedance test fixture, including an upper handle 1, a lower handle 3 rotatably connected to the outside of the upper handle 1, a bolt 4 rotatably connected to the inside of the lower handle 3, the bolt 4 penetrating the inside of the upper handle 1, a nut 6 threadedly connected to the outside of the bolt 4, a limit block 7 provided at the bottom of the nut 6, the limit block 7 being fixedly connected to the back end of the lower handle 3, a torsion spring 2 rotatably connected to the outside of the bolt 4, the bottom of the torsion spring 2 contacting the inside of the lower handle 3, the top of the torsion spring 2 contacting the inside of the upper handle 1, an adjustment mechanism 8 provided inside the upper handle 1, an installation mechanism 5 provided on the left side inside the upper handle 1, and a conductive block 9 provided inside the installation mechanism 5.

[0029] The adjustment mechanism 8 includes a connecting plate 85, which is fixedly connected to the inside of the upper handle 1. A first threaded rod 84 is rotatably connected to the right side of the connecting plate 85. A fixing plate 82 is rotatably connected to the periphery of the first threaded rod 84. The fixing plate 82 is fixedly connected to the right side of the upper handle 1. A nut 83 is fixedly connected to the right side of the first threaded rod 84. A pressing roller 81 is threadedly connected to the periphery of the first threaded rod 84. Slider blocks 86 are fixedly connected to the front and rear sides of the pressing roller 81. A reinforcing block 87 is fixedly connected to the inside of the upper handle 1.

[0030] Furthermore, a groove corresponding to the movement trajectory of the slider 86 is provided on the inner side of the upper handle 1, and the slider 86 is slidably connected inside the groove. Through the groove, the slider 86 can slide on the inner side of the upper handle 1. The slider 86 can limit the movement of the extrusion roller 81, making the extrusion roller 81 more stable during movement.

[0031] Furthermore, an arc-shaped hole corresponding to the position of the nut 83 is provided on the inner side of the reinforcing block 87. Through the arc-shaped hole, the operator can easily use tools to rotate the nut 83, so that the nut 83 can drive the first threaded rod 84 to rotate.

[0032] Furthermore, the limiting block 7 is set at the bottom of the nut 6, and the inner side of the limiting block 7 is in contact with the outer side of the nut 6. The limiting block 7 can limit the nut 6, so that when the bolt 4 rotates, it is not easy to drive the nut 6 to rotate.

[0033] Example 2

[0034] Please see Figure 1-5Furthermore, based on Embodiment 1, the installation mechanism 5 further includes a plug rod 51, which is inserted into the inner side of the upper handle 1. A threaded plate 53 is fixedly connected to the outer side of the plug rod 51. A limit rod 52 is slidably connected inside the threaded plate 53. A pressure head 56 is fixedly connected to the outer side of the limit rod 52. A second threaded rod 54 is rotatably connected to the outer side of the threaded plate 53. A rotating disk 55 is fixedly connected to the outer side of the second threaded rod 54. The pressure head 56 is fixedly connected to the outer side of the conductive block 9.

[0035] Furthermore, there are two pressure heads 56, which are respectively located on the outside of the upper handle 1 and the lower handle 3. When the upper handle 1 and the lower handle 3 are rotated, the pressure heads 56 can be rotated, so that the pressure heads 56 can be opened to facilitate clamping and fixing of the electrode sheet.

[0036] Furthermore, the inner side of the pressure head 56 is provided with a fixing groove corresponding to the movement trajectory of the threaded plate 53, and the threaded plate 53 is slidably connected inside the fixing groove. The fixing groove can limit the movement of the threaded plate 53, making the threaded plate 53 more stable during movement.

[0037] In actual operation, when this device is used, when it is necessary to install the pressure head 56 on the outside of the upper handle 1 and the lower handle 3, place the pressure head 56 on the outside of the upper handle 1 and the lower handle 3, manually rotate the rotating disk 55, so that the rotating disk 55 drives the second threaded rod 54 to rotate, so that the second threaded rod 54 drives the threaded plate 53 to move, so that the threaded plate 53 can drive the insertion rod 51 to insert into the pressure block, so that the pressure head 56 can be quickly installed on the outside of the upper handle 1 and the lower handle 3.

[0038] When it is necessary to clamp the electrode, press the upper handle 1 and the lower handle 3 up and down to compress the torsion spring 2, so that the two pressure blocks move away from each other. Place the electrode between the two pressure blocks, release the force on the upper handle 1 and the lower handle 3, and the upper handle 1 and the lower handle 3 will move the pressure blocks through the elastic force of the torsion spring 2. The pressure blocks will then move the conductive block 9, which will clamp and fix the electrode, making it convenient for the staff to perform a blocking test on the clamped electrode.

[0039] When it is necessary to adjust the clamping force of the upper handle 1 and the lower handle 3, the nut 83 is rotated by the slotted bolt 4, so that the nut 83 can drive the first threaded rod 84 to rotate, so that the first threaded rod 84 can drive the extrusion roller 81 to move, so that the extrusion roller 81 can extrude the torsion spring 2, and adjust the elastic force of the torsion spring 2, so that the pressure between the two pressure blocks can be adjusted, so that the device can clamp the electrode sheets after different times, making the electrode sheets less likely to be damaged.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
