Abstract
The utility model discloses a battery cover sealed by adopting a ball shaped safety valve, which comprises a middle cover, a groove containing all injecting holes positioned on the middle cover and a sheet cover plate matching at the upper end, each injecting hole is matched and positioned with a ball shaped safety valve at the upper port. The utility model has the advantages of simple structure, small combination clearance between the cover plate and the middle cover, no easy deformation, compact combination between the ball shaped safety valve and the injecting hole, good sealing performance, good acid resistance, stable pressure of valve opening and closing, convenient installation and disassembly and convenient maintenance.
Description
Technical field
The utility model relates to a kind of battery cap, refers in particular to a kind of battery cap that adopts the ball safety valve sealing.
Background technology
Lead acid accumulator needs sealing after injecting electrolyte, the general some liquid injection holes of design that in storage battery, cover, by on liquid injection hole, putting the rubber fur cap to realize sealing to internal storage battery, on fur cap, add upper cover plate again and normal open and close valve pressure is arranged with the control fur cap, its cover plate adopts seal or ultrasonic wave sealing or heat-sealing that its position is fixed mostly, the shortcoming of this frame mode is that cover plate unloads difficulty, the working service of inconvenient storage battery, and As time goes on the rubber fur cap easily wears out, and then lose open and close valve pressure, cause the storage battery premature failure.
The part storage battery is provided with caulking groove in the middle cover both sides, at the cover plate side chimb is set, resembling the drawer sample between cover plate and middle cover pushes, so that cover plate can be dismantled during battery service, this structure has made things convenient for the dismounting of cover plate, but cover plate is yielding, very easily have influence on the safety valve operate as normal of its below, also have by in cover and set up the operate as normal that the liquid feeding cap guarantees safety valve in addition, but its frame mode production and processing technology complexity increased cost of goods manufactured.
Summary of the invention
The utility model provides that a kind of simple in structure, good airproof performance, acid resistance are good, open and close valve pressure stability, cover plate easy installation and removal, battery cap easy to maintenance.
A kind of battery cap that adopts ball safety valve sealing comprises middle cover, containing of covering in being located at received the groove of all liquid injection holes and the sheet cover plate that the upper end cooperates thereof, and described each liquid injection hole upper port all is equipped with ball safety valve.
Described each liquid injection hole upper port forms the holding tank that cooperates ball safety valve to the expansion of periphery radian.
Between two row's liquid injection holes, is provided with the twice caulking groove in the described groove, cover plate be provided with some to the chimb of caulking groove corresponding matching.
Described groove is provided with several location holes, and correspondence is provided with alignment pin on the cover plate.
Described groove edge is provided with the plurality of rows gas port.
The utility model is simple in structure, good sealing effect, detachable cover plate convenient, adopts ball safety valve to replace traditional fur cap to seal, and acid resistance is good, and the open and close valve pressure stability is difficult for being flown by the gas bullet; By in cover and the caulking groove track be set and correspondence on the cover board is provided with chimb, the location hole and the alignment pin of corresponding matching are set on groove and cover plate respectively simultaneously, realize can not becoming flexible after cover plate inserts by the embedding mutually of caulking groove and chimb and the win cooperation of crossing of location hole and alignment pin; Ball safety valve and liquid injection hole conformability are good, and sealing effectiveness is good.

Embodiment
As shown in Figure 1, a kind of battery cap that adopts the ball safety valve sealing, comprise middle cover 1, be located at and receive the groove 12 of all liquid injection holes 11 containing on the middle cover 1, and sheet cover plate 3, liquid injection hole 11 upper port all are equipped with ball safety valve 2, be better fit, liquid injection hole 11 upper port form to the expansion of periphery radian and cooperate the holding tank 4 that holds ball safety valve 2, as shown in Figure 2.
Shown in Fig. 3,4, be provided with twice caulking groove 13 in the groove 12 between two row's liquid injection holes 11, cover plate 3 is provided with the chimb 21 of three pairs of corresponding matching caulking grooves 13, is provided with several location holes 14 in the groove 12, correspondence is provided with alignment pin 22 on the cover plate 2, and groove 12 edges offer plurality of rows gas port 15.
When ball safety valve 2 is installed, acidproof oil or vaseline need only be coated with the holding tank 4 of liquid injection hole 11 in ball safety valve 2 surfaces, ball safety valve 2 is put into holding tank 4 to get final product, ball safety valve 2 combines with holding tank 4 closely like this, good sealing effect, and the ball safety valve acid resistance is good, and the open and close valve pressure stability is difficult for being flown by the gas bullet.
When cover plate 3 is installed, in the caulking groove 13 in the middle of chimb 21 corresponding insertion middle cover 1 grooves 12 of cover plate 3, push as drawer, and 22 correspondences of the alignment pin on the cover plate 3 are pressed in the location hole 14 of middle cover 1 groove 12, cover plate 3 closely pastes mutually with middle cover 1 like this, and cover plate 3 is difficult for loosening distortion.
And dismounting only needs to aim at exhaust outlet 15 with instrument and lever up alignment pin 22 during cover plate 3, unloads lower cover 3, just can take out ball safety valve 2, and is easy to operate.
