Described box hat battery core block, also comprise pressing plate, upper sealing ring, lower seal and rivet, described pressing plate, upper sealing ring, cover plate, lower seal and lug stack gradually, and described rivet wears and pressing plate, upper sealing ring, cover plate, lower seal and lug described in rivet clasp successively.
A kind of box hat battery core, comprise box hat, core, electrolyte and block, described box hat and block are fixed as one formation can, described electrolyte and core are sealed in described can, also comprise sealing spheroid, described block comprises cover plate and lug, and described cover plate and lug insulate and be fixed as one, described cover plate has the liquid injection hole run through up and down, and described sealing spheroid and described cover plate magnetic absorption also block described liquid injection hole.
Described liquid injection hole comprises the through hole and transitional pore that are connected, the lower surface of described cover plate extends tubular body downwards, described through hole is crossed by described tubular body, the aperture of described transitional pore is up big and down small, the top of described transitional pore and the upper surface of described cover plate are connected, the bottom of described transitional pore and described through hole are connected, and the bottom of described sealing spheroid embeds in described through hole.
The beneficial effects of the utility model are: because sealing spheroid and cover plate can magnetic absorptions and block liquid injection hole temporarily, and can by controlling the magnetic intensity magnetized, the magnetic attraction of sealing spheroid is made to be unlikely to excessive, make waste gas when changing into, the electrolyte of many notes easily can back down sealing spheroid and discharge, and then artificial when effectively can reduce manufacture and reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model box hat battery core block;
Fig. 2 is the cutaway view of Fig. 1 along A-A direction.
Embodiment
As shown in Figures 1 and 2, box hat battery core block comprises rivet 1, pressing plate 2, upper sealing ring 3, cover plate 4, lower seal 5 and lug 6, wherein, rivet 1 passes pressing plate 2, upper sealing ring 3, cover plate 4, lower seal 5 and lug 6 successively, then integral for these part rivet clasps.The note hole at night 7 that cover plate has one to run through, this liquid injection hole 7 comprises the transitional pore 14 and through hole 13 that are connected, and the lower surface 15 of cover plate extends tubular body 8 downwards, and through hole 13 is crossed by this tubular body 8.Transitional pore 14 can be conical or circular arc, and its aperture is up big and down small, and the top of transitional pore 14 is connected cover plate upper surface 9, and the bottom of transitional pore 14 is connected through hole 13.When needs forever seal to box hat battery core, a steel ball 11 squeezed into liquid injection hole 7 and rests in tubular body 8, playing the effect of forever sealing to battery core.In cover plate 4 and sealing spheroid 11 two parts, a material is the magnetic material that can be magnetized (magnetization), as No. 45 steel, S2 steel, TS2 steel, chrome-vanadium steel, carbon steel, wolfram steel, chromium steel or cobalt steels etc., another material is magnetic material, as martensitic stain less steel, ferritic stainless steel, austenite or ferrite (two-phase) stainless steel.Magnetize to one of cover plate liquid injection hole position, sealing spheroid, one of cover plate liquid injection hole position, sealing spheroid 11 is made forever to have magnetic, as cover plate liquid injection hole position has permanent magnetism, the sealing spheroid 11 of magnetic material can be attracted on liquid injection hole 7 and seal liquid injection hole 7, or there is permanent magnetism as sealing spheroid, the liquid injection hole that sealing spheroid also can attracted to magnetic material seals liquid injection hole.Both can certainly have permanent magnetism.
When magnetizing, control well sealing spheroid, cover plate liquid injection hole position magnetic field intensity, make sealing spheroid reliably be adsorbed onto on cover plate liquid injection hole and to cover liquid injection hole, air-isolation, be unlikely to again to adsorb sacrifices consisting of an ox, a sheep and a pigly to lean on, note electrolyte more, change into waste gas and easily can back down sealing spheroid and eject.
Preference, cover plate material is martensitic stain less steel, ferritic stainless steel, austenite or ferrite (two-phase) stainless steel etc., and steel ball material is No. 45 steel, S2 steel, TS2 steel, chrome-vanadium steel, carbon steel, wolfram steel, chromium steel or cobalt steels etc.
If desired, can at the hole wall 10 of transitional pore 14 recessed several (such as three) air discharge ducts 12 of formation downwards, (now seal spheroid 11 and be not driven into tubular body 8 position) when making sealing spheroid 11 cover liquid injection hole 7, there is small gas circuit to exist, do not need to back down sealing spheroid for a small amount of waste gas when changing into and also can overflow.
A kind of box hat battery core, comprise block, sealing spheroid, core, box hat and electrolyte, block, box hat and sealing spheroid form a can, core, electrolyte are positioned in the seal cavity that can crowds around, wherein, block comprises rivet, pressing plate, upper sealing ring, cover plate, lower seal and lug.The cover plate of battery core, the material one of sealing spheroid two parts are the magnetic material that can be magnetized (magnetization), as No. 45 steel, S2 steel, TS2 steel, chrome-vanadium steel, carbon steel, wolfram steel, chromium steel or cobalt steels etc., another is magnetic material, as martensitic stain less steel, ferritic stainless steel, austenite or ferrite (two-phase) stainless steel etc.Magnetize to one of cover plate liquid injection hole position, sealing spheroid, one of cover plate liquid injection hole position, sealing spheroid is made forever to have magnetic, as cover plate liquid injection hole position has permanent magnetism, the sealing spheroid of magnetic material can be attracted on liquid injection hole and seal liquid injection hole, or there is permanent magnetism as sealing spheroid, the liquid injection hole that sealing spheroid also can attracted to magnetic material seals liquid injection hole.Both can certainly have permanent magnetism.
Cover plate, sealing spheroid material all adopt magnetic material, and magnetize to one, make sealing spheroid can be magnetically drawn gravitational attraction and cover liquid injection hole, moisture in energy air-isolation, control the magnetic intensity magnetized well, make the magnetic attraction of sealing spheroid be unlikely to excessive, the electrolyte of waste gas when changing into, many notes easily can back down sealing spheroid and discharge.Not only instead of the gummed paper of existing interim sealing tech employing, cotton, toilet paper, and before beating sealing spheroid, sealing spheroid is in place on liquid injection hole in advance, when beating sealing spheroid to needs, saves and seals the spheroid step at liquid injection hole in place.
Above content is in conjunction with concrete execution mode further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made.
