Abstract
The utility model discloses a sealing structure of an acid injection funnel for a lead-acid battery. The funnel bottom is a plane, a rubber gasket whose boundary dimension is consistent with the funnel bottom is arranged between the plane and the upper surface of an upper battery cover, and a rubber seal ring is arranged in a step combination position of a funnel joint and a valve port of the upper battery cover. With the adoption of the structure, the support function can be enhanced after the funnel is mounted, the funnel cannot incline, the gasket is balanced in stress, and double seal is performed, so that the leakproofness is guaranteed, acid leakage and seepage are avoided, and the battery quality is further improved.
Description
Technical field
The utility model relates to a kind of acid filling funnel for lead acid accumulator production process, is specifically lead acid accumulator acid filling funnel hermetically-sealed construction.
Background technology
Lead acid accumulator acid filling funnel is conventional frock in battery acid filling process.Acid filling funnel generally adopts ABS+PVC pipe to be made, and its effect injects the electrolyte into inside battery, plays storage, guide functions.Lead acid accumulator industry at present, battery acid filling funnel generally adopts bayonet coupling, has the features such as easy to connect, easy to operate.
The upper part of common acid filling funnel is generally cylindrical, and lower part is taper with bayonet coupling, and there is rubber seal top, bayonet socket place, when bayonet socket coordinate with the inner bayonet of cell cover valve port tighten after formation seal.At present manufacturer, in order to improve acid filling efficiency, directly increases funnel height, increases the volume of funnel, and electrolyte is all put into funnel, then allows under its nature and infilters into battery.Because bell mouth is less, can make like this funnel occur top heavy situation, funnel crank, easily crooked, the rubber ring pressurized of bottom interface is unbalanced, and pressure is excessive on one side, another side pressure is too small, thereby causes electrolyte in carrying and formation process go out or permeate from the too small effluent of pressure.The outflow of electrolyte or infiltration easily form short circuit in battery formation process, cause battery surface burn and corrosion output pole, and short circuit simultaneously produces spark, produces hydrogen and oxygen in battery formation process, easily sets off an explosion.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and provides a kind of funnel to install steadily, and sealing is reliable, can improve the lead acid accumulator acid filling funnel hermetically-sealed construction of acid filling effect and battery quality.
The technical solution of the utility model is: a kind of lead acid accumulator acid filling funnel hermetically-sealed construction, comprise acid filling funnel, cell cover and sealing ring, its improvements are that the bottom of described acid filling funnel is the plane perpendicular to hopper centre's line, between this plane and cell cover surface, be provided with the consistent rubber gasket of overall dimension and funnel bottom, there is rubber seal the interior step junction at the outer step of funnel interface and cell cover valve port place.
Acid filling funnel of the present utility model changes bottom into plane by the conical surface, and increase the flat ring-shaped rubber sealing gasket that a profile and funnel bottom are consistent in this plane and cell cover contact site, make funnel install after strengthen supporting role, can not occur crooked, the equilibrium of sealing gasket pressurized.Place sealing ring simultaneously on funnel bayonet socket top, form double sealing structure, guarantee the sealing of funnel installation place, be not easy to occur leaking sour situation.The utility model has solved existing acid filling funnel crank and leakage acid, has oozed sour situation, thereby improves acid filling effect, guarantees battery quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, the bottom of acid filling funnel 1 is the plane perpendicular to its center line, between the upper surface of this plane and cell cover 3, be provided with the rubber gasket 2 that overall dimension and funnel bottom are consistent, funnel interface and cell cover valve port place are tightened by bayonet socket, there is rubber seal 4 both step junctions, form dual-seal.
Claims (1)
1. a lead acid accumulator acid filling funnel hermetically-sealed construction, comprise acid filling funnel, cell cover and sealing ring, the bottom that it is characterized in that described acid filling funnel is the plane perpendicular to hopper centre's line, between this plane and cell cover surface, be provided with the consistent rubber gasket of overall dimension and funnel bottom, there is rubber seal the interior step junction at the outer step of funnel interface and cell cover valve port place.
