[0019] 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.

[0020] Example: Figures 1-4 As shown, this utility model provides a cathode assembly for hydrogen production by water electrolysis, including a cathode mechanism 1 and an electrolytic cell 2. The cathode mechanism 1 is fixedly inserted into the electrolytic cell 2. The cathode mechanism 1 is provided with a limiting mechanism 3 for cooperation. An anode body 4 for cooperation with the cathode mechanism 1 is fixedly inserted into one side of the electrolytic cell 2.

[0021] The cathode mechanism 1 includes an outer tube 11. Symmetrically distributed through holes 21 are formed on the other side of the electrolytic cell 2, and the outer tube 11 is fixedly inserted into the through holes 21. A through groove 12 is formed through the outer tube 11, and an inner tube 13 is rotatably inserted into the inner side of the outer tube 11. A through groove 14, which cooperates with the through groove 12, is formed through the inner tube 13. A detachable insert plate 15 is inserted into the upper inner side of the inner tube 13. A cathode body 16 is fixedly inserted into the middle of the insert plate 15, and a fixing rod 17 is slidably inserted into the upper end of the outer tube 11. A through hole 112 is formed through the middle of the insert plate 15, and the cathode body 16 is fixedly inserted into the through hole 112. The through hole 112 ensures the stable insertion of the cathode body 16. A guide plate 113 is integrally formed on the upper inner side of the inner tube 13, and the insert plate 15 can be slidably sleeved on the guide plate 113. The insertion plate 15 has a guide groove 114, and the guide plate 113 can be slidably locked in the guide groove 114. The cooperation between the guide plate 113 and the guide groove 114 ensures the accurate insertion of the insertion plate 15. The top of the insertion plate 15 is fixedly connected to a gripping rod 115, and the gripping rods 115 are symmetrically distributed. The top of the insertion plate 15 has symmetrically arranged insertion holes 116, and the gripping rods 115 are fixedly inserted in the insertion holes 116. The cooperation between the insertion holes 116 and the gripping rods 115 facilitates the rotation and movement of the insertion plate 15. The fixing rod 17 is fixedly sleeved with a push plate 18, and a spring 19 is fixedly installed on one side of the push plate 18. The end of the spring 19 is fixedly connected to the inner wall of the outer tube 11. The upper end of the inner tube 13 has symmetrically arranged fixing holes 110, and one end of the fixing rod 17 can be slidably inserted in the fixing holes 110.

[0022] By adopting the above technical solution, during use, the corresponding push plate 18 needs to be pushed to move, thereby driving the corresponding fixing rod 17 to move and squeeze the corresponding spring 19. When the fixing rod 17 is completely separated from the corresponding fixing hole 110, stop pushing the corresponding push plate 18 and rotate the corresponding grip rod 115, thereby driving the corresponding inner tube 13 to rotate. Stop rotating the corresponding grip rod 115 and release the corresponding push plate 18 when the corresponding inner tube 13 is rotated 180 degrees. At this time, the spring 19 will drive the corresponding push plate 18 to reset, thereby driving the corresponding fixing rod 17 to reset and insert it into another corresponding fixing hole 110. At this time, the second through slot 14 will be connected to the corresponding through slot 12. Then, the corresponding cathode body 16 is wired and connected to the power according to the usage requirements during use. In addition, when it is necessary to replace the corresponding cathode body 16, the corresponding inner tube 13 is reversed and reset, and the corresponding through slot 14 and the corresponding through slot 12 are misaligned. Then, the corresponding cathode body 16 can be disassembled and replaced.

[0023] The limiting mechanism 3 includes a limiting rod 31, which is slidably inserted into the inner tube 13. A push ring 32 is fixedly sleeved at the end of the limiting rod 31. A push hole 34 is provided on the push ring 32 for cooperation. The push hole 34 facilitates the operation of the push ring 32. A spring 33 is fixedly installed on one side of the push ring 32, and the end of the spring 33 is fixedly connected to the outer wall of the inner tube 13. A limiting hole 111 is provided on the insertion plate 15, and one end of the limiting rod 31 can be slidably inserted into the limiting hole 111.

[0024] By adopting the above technical solution, during use, the two push rings 32 are pushed in sequence, which can drive the corresponding limiting rod 31 to move and stretch the corresponding spring 33. When the distance between the push ring 32 and the corresponding inner tube 13 is moved to the maximum, the push ring 32 is stopped and any unused cathode body 16 and the corresponding insert plate 15 are inserted into the corresponding inner tube 13. When the corresponding guide groove 114 moves to the bottom along the corresponding guide plate 113, the push ring 32 is released. Then the spring 33 will drive the push ring 32 to reset, which can drive the corresponding limiting rod 31 to reset and insert it into the corresponding limiting hole 111. This allows the insert plate 15 and the cathode body 16 to be easily fixed. In subsequent use, the insert plate 15 and the cathode body 16 can be removed by reversing the above steps.

[0025] Working principle: In use, push the two push rings 32 in sequence, which will drive the corresponding limit rod 31 to move and stretch the corresponding spring 33. When the distance between the push ring 32 and the corresponding inner tube 13 is moved to the maximum, stop pushing the corresponding push ring 32 and insert any unused cathode body 16 and the corresponding insert plate 15 into the corresponding inner tube 13. When the corresponding guide groove 114 moves to the bottom along the corresponding guide plate 113, release the corresponding push ring 32. Then the spring 33 will drive the corresponding push ring 32 to reset, which will drive the corresponding limit rod 31 to reset and insert it into the corresponding limit hole 111. This will allow the corresponding insert plate 15 and cathode body 16 to be easily fixed. In subsequent use, the corresponding insert plate 15 and cathode body 16 can be removed by reversing the above steps.

[0026] Next, the corresponding push plate 18 needs to be pushed to move, thereby driving the corresponding fixing rod 17 to move and squeeze the corresponding spring 19. When the fixing rod 17 is completely separated from the corresponding fixing hole 110, stop pushing the corresponding push plate 18 and rotate the corresponding grip rod 115, thereby driving the corresponding inner tube 13 to rotate until the corresponding inner tube 13 is rotated 180 degrees. Stop rotating the corresponding grip rod 115 and release the corresponding push plate 18. At this time, the spring 19 will drive the corresponding push plate 18 to reset, thereby driving the corresponding fixing rod 17 to reset and insert it into another corresponding fixing hole 110. At this time, the second through slot 14 will be connected to the corresponding through slot 12. Then, the corresponding cathode body 16 is wired and connected to the power according to the usage requirements during use. In addition, when the corresponding cathode body 16 needs to be replaced, the corresponding inner tube 13 is reversed and reset, and the corresponding through slot 14 and the corresponding through slot 12 are misaligned. Then the corresponding cathode body 16 can be disassembled and replaced.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
