[0026] A pH electrode protection casing structure with a junction box, including a casing body 1. An immersion tube 2 is integrally formed at the bottom end of the casing body 1. An electrode body 3 is sleeved between the inside of the casing body 1 and the immersion tube 2; a junction box body 4 is arranged at the top end of the casing body 1. A disassembly mechanism is arranged between the casing body 1 and the junction box body 4. The disassembly mechanism includes a threaded sleeve 8. The threaded sleeve 8 is integrally formed at the top end of the casing body 1. An external thread of the threaded sleeve 8 is threadedly connected with a movable sleeve 9. A guide ring 10 is arranged at one end of the junction box body 4 located inside the movable sleeve 9. The disassembly mechanism further includes a detachable joint 11. One end of the detachable joint 11 is connected to the junction box body 4 through a linear wire 16. The other end of the detachable joint 11 is connected with a spring wire 12.
