Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a totally enclosed leak protection liquid lead acid battery, includes battery cover 1 and utmost point post 2, and leak protection packing ring 4 is connected to 1 screw thread of battery cover, and blind hole 9 has been seted up at leak protection packing ring 4 top, and the vertical cross-section of blind hole 9 is squarely, provides the point of application of force for the rotation of leak protection packing ring 4 through blind hole 9, and the battery cover 1 is connected to the 4 screw threads of leak protection packing ring of being convenient for. Sealed glue 5 has been pour between battery cover 1 and utmost point post 2, and utmost point post 2 is equipped with rather than integrated into one piece's spacing ring 3, is equipped with bulge loop 6 on the spacing ring 3, and bulge loop 6 inboard and the outside all is equipped with first sealing washer 7.

As shown in fig. 2, the first sealing ring 7 is an i-shaped sealing ring, the first insert ring 701 and the second insert ring 702 are integrally formed with the first sealing ring 7, and the vertical cross sections of the first insert ring 701 and the second insert ring 702 are square. During first sealing washer 7 was through sealed 5 of gluing of first caulking ring 701 embedding to and during second caulking ring 702 embedding spacing ring 3, increased first sealing washer 7 and sealed 5 and spacing ring 3 area of contact, improved sealed effect. The convex ring 6 and the limit ring 3 are integrally formed, and the vertical section of the convex ring 6 is square. In this embodiment, the two convex rings 6 are arranged, the two convex rings 6 and the first sealing ring 7 positioned on the inner side and the outer side of the convex rings 6 form a labyrinth seal structure, when the labyrinth seal structure has a gap, electrolyte in the lead-acid storage battery enters the gap to generate a labyrinth effect, namely, fluid generates resistance through the labyrinth and causes the flow rate of the fluid to be reduced, so that leakage resistance is achieved. Therefore, the convex ring 6 and the first sealing ring 7 enable the bottom of the sealing glue 5 to have good sealing effect.

As shown in fig. 3, the second sealing ring 8 is arranged on the top of the sealant 5, the second sealing ring 8 is integrally formed by a sealing ring 801 and a third caulking ring 802, the sealing ring 801 is abutted to the leakage-proof gasket 4, the third caulking ring 802 is embedded into the sealant 5, and the third caulking ring 802 increases the contact area between the second sealing ring 8 and the sealant 5, thereby improving the sealing effect. The threaded connection department with leak protection packing ring 4 on the battery cover 1 is the internal thread, and this internal thread coating has precoated formula thread sealing coating, in this embodiment, precoated formula thread sealing coating adopts Loctite 503 library-Seal precoated type waterborne thread sealing gum of producing of Germany HENKEL company, has low viscosity, non-toxicity, anti-chemical good, not corroded by electrolyte's advantage, when it is dry, fill the clearance of battery cover 1 and leak protection packing ring 4, avoid electrolyte to leak. Therefore, the first seal ring 7 and the leakage-proof gasket 4 provide a good sealing effect on the top of the sealant 5.

In conclusion, the top and the bottom of the sealant 5 have good sealing effect, namely, the full-sealing and leakage-proof functions are realized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
