In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.
[0030] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a control mechanism and an alkaline electrolytic cell hydrogen production equipment.
[0031] In the first embodiment, a pipeline 2 is fixed to the output end of the electrolytic cell main body 1. An electric valve main body 3 is provided on the surface of the pipeline 2. A bolt 4 is inserted through the end surface of the electric valve main body 3. A gas storage tank main body 21 is fixed to the port of the pipeline 2.
[0032] A notch 13 is formed on one end surface of a nut 6. A positioning block 5 is provided on the inner wall surface of the notch 13. A receiving groove 17 is formed inside the nut 6. A spring 16 is provided on the inner wall of the receiving groove 17. Due to the elasticity of the spring 16, the reset of the spring 16 will push a baffle 19 to move in the receiving groove 17, so that a limiting block 20 is clamped into a limiting groove 12 through a connecting groove 15. Since the positioning block 5 can only move horizontally on the surface of the bolt 4, and the nut 6 can only rotate on the surface of the bolt 4, the nut 6 and the positioning block 5 are fixed to the surface of the bolt 4 under the limitation of the limiting block 20.
[0033] On the basis of the first embodiment, in order to prevent the bolt 4 from loosening when the electric valve main body 3 is connected and fixed to the pipeline 2, a sliding groove 8 is formed on the surface of the bolt 4, so that the positioning block 5 can only move horizontally on the surface of the bolt 4. An annular groove 14 is formed on the inner wall surface of the notch 13. A connecting groove 15 is formed on the bottom surface of the inner wall of the annular groove 14. An annular block 11 is provided on the inner wall of the annular groove 14. A connecting ring 10 is fixed to the surface of the annular block 11. A positioning block 5 is fixed to the surface of the connecting ring 10.
[0034] A limiting groove 12 is formed on the surface of the annular block 11. A sliding block 9 is fixed to the inner wall surface of the positioning block 5. A through groove 18 is formed on the inner wall surface of the storage groove 17. A baffle 19 is provided on the inner wall of the storage groove 17. A limiting block 20 is fixed to the end surface of the baffle 19. Under the limitation of the limiting block 20, the nut 6 and the positioning block 5 are fixed on the surface of the bolt 4, and at the same time, the anti-loosening of the bolt 4 is realized when the electric valve body 3 is connected and fixed to the pipeline 2. A pushing block 7 is fixed to the arc surface of the baffle 19.
[0035] There are multiple groups of sliding blocks 9, and the multiple groups of sliding blocks 9 are circumferentially distributed on the inner wall surface of the positioning block 5. There are multiple groups of sliding grooves 8, and the multiple groups of sliding grooves 8 are circumferentially distributed on the outer surface of the bolt 4, and the sliding blocks 9 correspond to the sliding grooves 8. The sliding blocks 9 are clamped in the sliding grooves 8, and the two are movably connected, so that the positioning block 5 can only move horizontally on the surface of the bolt 4.
[0036] The diameter of the annular block 11 is the same as that of the annular groove 14, and the diameter of the connecting ring 10 is the same as that of the notch 13. The diameter of the annular block 11 is larger than that of the connecting ring 10, and the annular block 11 corresponds to the annular groove 14. The annular block 11 is clamped in the annular groove 14, and the two are movably connected, so that the nut 6 can only rotate on the surface of the bolt 4.
[0037] There are multiple groups of limiting blocks 20, and the multiple groups of limiting blocks 20 are circumferentially distributed on the surface of the baffle 19. The limiting blocks 20, the connecting groove 15 and the limiting groove 12 correspond to each other. The limiting blocks 20 are clamped in the connecting groove 15 and the limiting groove 12. Under the limitation of the limiting blocks 20, the nut 6 and the positioning block 5 are fixed on the surface of the bolt 4, and at the same time, the anti-loosening of the bolt 4 is realized when the electric valve body 3 is connected and fixed to the pipeline 2, and they are movably connected.
[0038] There are multiple groups of through grooves 18, and the multiple groups of through grooves 18 are circumferentially distributed on the inner wall of the storage groove 17. The through grooves 18 penetrate to the outer surface of the nut 6. There are multiple groups of pushing blocks 7, and the multiple groups of pushing blocks 7 are circumferentially distributed on the outer surface of the baffle 19. The pushing blocks 7 correspond to the through grooves 18. The pushing blocks 7 are clamped in the through grooves 18, and the two are movably connected.
[0039] In actual use, when connecting the pipeline 2 and the electric valve body 3, first insert the bolt 4 through the connecting flanges of the pipeline 2 and the electric valve body 3. At the same time, push the push block 7 to move in the through groove 18 to accommodate the spring 16. Then, align the slider 9 with the sliding groove 8, and fit the nut 6 onto the bolt 4 to fix the connecting flanges of the pipeline 2 and the electric valve body 3. At this time, stop pushing the push block 7. Due to the elasticity of the spring 16, the spring 16 will reset and push the baffle 19 to move in the receiving groove 17, so that the limiting block 20 is clamped into the limiting groove 12 through the connecting groove 15. Since the positioning block 5 can only move horizontally on the surface of the bolt 4, and the nut 6 can only rotate on the surface of the bolt 4, under the limitation of the limiting block 20, the nut 6 and the positioning block 5 are fixed on the surface of the bolt 4. At the same time, the anti-loosening of the bolt 4 is realized when the electric valve body 3 is connected and fixed to the pipeline 2. This structure is simple and easy to operate, which is beneficial to improving its use effect.
