值得注意的是,磁鐵環20具有一厚度t,每一密封環40具有一直徑D,每一環形槽17、53具有一寬度w及一深度d。於本實施例中,寬度w係大於直徑D,且直徑D係大於深度d,藉此各密封環40會凸出在各環形槽17、53外,使得側蓋環50在鎖固時磁鐵環20能夠接觸各密封環40以縱向迫緊,從而讓各密封環40產生彈性變形。又,防蝕膜30具有遮蔽側平面22的一遮蔽長度l。遮蔽長度l和1/2寬度w的總和係大於厚度t,藉此能夠確保各密封環40係抵接在防蝕膜30上而起到密封的效果,從而避免腐蝕性化學物質自防蝕膜30和密封環40之間滲入而腐蝕磁鐵環20。於本實施例中,遮蔽長度l係和磁鐵環20的厚度t等長,但本發明不以此為限。It should be noted that the magnet ring 20 has a thickness t, each sealing ring 40 has a diameter D, and each annular groove 17, 53 has a width w and a depth d. In this embodiment, the width w is greater than the diameter D, and the diameter D is greater than the depth d, so that each sealing ring 40 will protrude outside each annular groove 17, 53, so that the magnet ring when the side cover ring 50 is locked 20 is capable of contacting each sealing ring 40 for longitudinal compression, so that each sealing ring 40 is elastically deformed. Moreover, the anti-corrosion film 30 has a shielding length l for shielding the side plane 22 . The sum of the shielding length l and the 1/2 width w is greater than the thickness t, thereby ensuring that each sealing ring 40 abuts against the anti-corrosion film 30 to play a sealing effect, thereby preventing corrosive chemicals from coming out of the anti-corrosion film 30 and The magnet ring 20 is corroded by penetration between the seal rings 40 . In this embodiment, the shielding length l is equal to the thickness t of the magnet ring 20 , but the invention is not limited thereto.
