Abstract
The invention provides a lead-acid storage battery housing structure consisting of an upper cover and a barrel body, wherein the back of the upper cover is provided with U-shaped grooves and concave troughs; as an improvement, each U-shaped groove is internally provided with a boss in the part connected with the corresponding concave trough, and the height of each boss is less than the depth of each U-shaped groove. The corresponding parts of the barrel wall of the barrel body are provided with notches, and the inner walls of the concave troughs are marked with scales. According to the invention, a glue solution poured into the U-shaped grooves and the concave troughs of the upper cover can be controlled quantitatively at the time of glue sealing of the barrel cover so as to avoid glue overflow when a conductive lead piece is inserted into the barrel wall of the barrel body, reduce waste, lower frequency of manual frictioning, and cut production cost.
Description
Technical field
The present invention relates to a kind of lead acid accumulator shell structure, belong to Lead-acid Battery Technology field.
Background technology
Lead acid accumulator housing is one of assembly of indispensability concerning battery, and its structure is generally injection molded by PP, ABS material, is divided into upper cover and staving two parts.Upper cover and staving generally adopt epoxide-resin glue to seal, and first pour in the U-type groove of upper cover by glue, then staving are overturn 180 °, form sealing by the U-type groove of staving upper-end part of driving insertion upper cover.Current battery industry many cells manufacturer, between monomer and monomer, the plumbous part of water conservancy diversion is generally higher than transverse plane on battery staving, and corresponding has a groove at cell cover position, and because the plumbous part volume of water conservancy diversion is comparatively large, therefore corresponding depression volume is also larger.When pouring glue in upper cover groove, because upper cover U-type groove is communicated with groove, the liquid level of the glue therefore in groove is consistent with the liquid level in U-type groove.For ensureing there are enough glue amounts in U-type groove, avoid bung rubber seal to leak gas, the glue amount in U-type groove is excessive, causes glue amount in groove also excessive.During bung rubber seal, staving and upper cover binding site overflow glue, need manually wipe; And in groove, glue amount is greatly excessive, due to the insertion of the plumbous part of water conservancy diversion, a large amount of glue can be overflowed, waste material and manpower, increase production cost.
Summary of the invention
The object of the invention is to the weak point overcoming existing battery container, provide a kind of and can reduce glue consumption in rubber seal process and workload, thus reduce the lead acid accumulator shell structure of production cost.
Technical scheme of the present invention is: a kind of lead acid accumulator shell structure, be made up of upper cover and staving, the upper cover back side is provided with U type groove and groove, and its improvements are provided with boss in the U-type groove of described U-type groove and groove connection position, and the height of this boss is less than the U-type groove degree of depth.
The bucket wall portion position that described staving corresponds to described boss is jagged, and this gap width is greater than boss thickness, and notch depth is consistent with boss height.
Described groove inner wall is provided with indicating graduation.
In the U-type groove of groove and U-type groove connecting portion, increase a boss, there is a boss each groove both sides, the amount of falling glue in boss restriction U-type groove.Open a gap in the corresponding bucket wall portion position of staving, really
Guarantor does not affect staving and coordinates with upper cover.
Accompanying drawing explanation
Fig. 1 is upper cover structure schematic diagram.
Fig. 2 is A-A place cutaway view in Fig. 1.
Fig. 3 is bucket body structure schematic diagram.
Embodiment
Further illustrate the embodiment of the present invention and good effect below.
As shown in the figure, the groove 2 at the upper cover I back side increases a boss 3, the boss 3 in each groove 2 both sides with the U-type groove of U-type groove 1 connecting portion is interior, and boss height is about the half of the U-type groove degree of depth; Open a gap 5 in the corresponding barrel wall portion position of staving II, width is slightly larger than boss 3 thickness, and the degree of depth is consistent with boss height, guarantees that not affecting staving coordinates with upper cover.
During rubber seal, first in upper cover U-type groove 1, pour glue into, boss height is the height of falling glue liquid surface, and unnecessary glue can flow in groove 2, guarantees that glue amount is inexcessive.And then in groove 2, pour glue into, groove inner wall is carved an indicating graduation 4, glue liquid surface and scale 4 maintain an equal level (scale less than 4 institute charging capacity when electrically conductive lead part inserts in groove 2, in groove glue amount full and without overflowing).Will load monomer and the soldered battery bucket of the plumbous part of water conservancy diversion overturns 180 °, staving bucket wall portion position is inserted in the U-type groove 1 of upper cover, and electrically conductive lead part inserts in groove 2, forms hermetically-sealed construction.
Realize determining height to glue liquid surface in U-type groove by U-type groove inner convex platform, thus arrive quantitative object, it is excessive to avoid with glue.By two, groove both sides boss, glue liquid surface in the glue in U-type groove and groove can be made to be in differing heights, groove inner wall is carved a scale, realize glue amount quantitative, thus when avoiding electrically conductive lead part to insert, glue overflows.Adopt inventive shell structure, the consumption of glue in bung seal process and artificial rubber can be greatly reduced, thus reduce production cost.
Claims (3)
1. a lead acid accumulator shell structure, is made up of upper cover and staving, and the upper cover back side is provided with U type groove and groove, it is characterized in that being provided with boss in the U-type groove of described U-type groove and groove connection position, and the height of this boss is less than the U-type groove degree of depth.
2., by lead acid accumulator shell structure described in claim 1, it is characterized in that described staving is jagged corresponding to the bucket wall portion position of described boss, this gap width is greater than boss thickness, and notch depth is consistent with boss height.
