Abstract
The utility model discloses a sealing structure for a lead-acid battery end post and a battery cover. The sealing structure for the lead-acid battery end post and the battery cover mainly comprises a battery end post, a soft glue sleeve and a battery cover, wherein the end post consists of a lead post and an internal copper core; the soft glue sleeve is arranged at the periphery of the lead post; the inner surface of the soft glue sleeve and the periphery of the lead post are correspondingly provided with concave-convex structures; the outer surface of the soft glue sleeve is a cone-shaped structure and is provided with annular saw-toothed bumps along the taper surface; and the outer surface of the soft glue sleeve is in close fit with the inner wall of a cone-shaped end post hole of the battery cover with the same taper. The sealing structure for the lead-acid battery end post and the battery cover has the beneficial effects that the concave-convex structures on the inner surface of the soft glue sleeve increase the binding force between the soft glue sleeve and the lead post as well as lengthen the distance of electrolyte permeating to the upper part of the battery end post along the lead post at the same time; the annular saw-toothed bumps uniformly distributed on the outer surface can play a multi-linear sealing effect so as to ensure the firmness; the soft glue sleeve slightly moves upwards along with the upward growth of a pole plate so that the soft glue sleeve is matched with the cone-shaped end post hole more closely and the sealing effect is better.
Description
Technical field
The utility model relates to the lead acid accumulator field, more specifically is the hermetically-sealed construction of a kind of lead acid accumulator newel post and battery cover.
Background technology
Domestic traction battery production now; The hermetically-sealed construction major part of battery newel post and battery cover is: battery newel post stretches out from the newel post hole on the battery cover; In the battery newel post of stretching out, put rubber sleeve from top to down; Embed under external force in the space of battery newel post and battery cover newel post hole inwall, the tight contact through contact-making surface between rubber sleeve, battery newel post, battery cover three reaches sealing effectiveness, prevents overflowing of acid.Thereby being complicated operation, rubber sleeve, the problem that this sealing means brings receive external force to make the easy excessive sour hidden danger of contact-making surface appearance of destroying of time spent; Along with upwards the growing up of direction of using the later stage pole plate, move on rubber sleeve is easy, destroy integral sealing effect.
Summary of the invention
The utility model technical problem to be solved is to provide the hermetically-sealed construction of a kind of lead acid accumulator newel post and battery cover; It can effectively solve present universal architecture complicated operation, easy take place the to overflow problem of acid, particularly uses the excessive sour problem that the later stage grows up and bring because of pole plate.
For addressing the above problem; The utility model adopts following technical scheme: the hermetically-sealed construction of a kind of lead acid accumulator newel post and battery cover; Mainly comprise the newel post of battery, soft gum cover and battery cover, newel post is made up of lead block and inner copper core, and it is characterized in that: the lead block periphery has soft gum cover; Soft gum cover inner surface and lead block periphery correspondence are provided with concaveconvex structure; The outer surface of soft gum cover is a pyramidal structure, and has the zigzag of annular protruding along the conical surface, and soft gum cover outer surface closely cooperates with battery cover taper newel post hole inwall with tapering.
Described soft balsam cover material is the acid-resistant, thermoplastic soft rubber, is socketed in the periphery of lead block.
Said soft balsam cover material is the acid-resistant, thermoplastic soft rubber, can be one with the lead block embedding and injection molding in advance like this.
During use; The battery newel post that has a soft gum cover stretches out from battery cover taper newel post hole in battery case, lid heat-sealing, thereby the zigzag convexity of the annular that the soft balsam of pyramidal structure puts can reach the purpose of sealing with closely cooperating with the taper newel post hole on the battery cover of tapering.
The beneficial effect of the utility model is: the concaveconvex structure of soft gum cover inner surface has also prolonged the distance that the suitable lead block of electrolyte is penetrated into battery newel post top when increasing soft gum cover and lead block adhesion; The zigzag convexity of the annular that soft gum cover outer surface is uniformly distributed with can play the effect of multilinear sealing, guarantees fixing; The soft gum cover of pyramidal structure has been considered the latency that pole plate is upwards grown up simultaneously, along with upwards growing up of pole plate, moves on soft gum cover is slight, thereby makes tightr that soft gum cover cooperates with taper newel post hole, and sealing effectiveness is better.Thereby make that easy to operate, sealing effectiveness is better, fixing is higher.
Description of drawings
Fig. 1 is the battery newel post cutaway view Amplified image that has rubber sleeve among the utility model embodiment;
Fig. 2 is the battery cover partial sectional view of the utility model;
Fig. 3 is the part assembling diagrammatic cross-sectional view of the utility model hermetically-sealed construction.
Among the figure, 1. rubber sleeve, 2. lead block, 3. copper core, 4. concaveconvex structure, 5. zigzag is protruding, 6. taper newel post hole, 7. battery cover, 8. battery case, 9. pole plate.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
Like Fig. 1,2, shown in 3, the hermetically-sealed construction of a kind of lead acid accumulator newel post and battery cover mainly comprises battery newel post, rubber sleeve 1 and battery cover 8; Battery newel post is made up of lead block 2 and inner copper core 3; Rubber sleeve 1 is directly injection-moulded in lead block 2 peripheries; Rubber sleeve 1 inner surface and lead block 2 periphery correspondences are provided with concaveconvex structure 4; The outer surface of rubber sleeve 1 is a pyramidal structure, and has the zigzag of annular protruding 5 along the conical surface, and rubber sleeve 1 outer surface closely cooperates with battery cover 7 taper newel post hole 6 inwalls with tapering.
When battery cover 7 seals with battery case 8; The battery newel post that has rubber sleeve 1 stretches out from the taper newel post hole 6 of battery cover 7; The band saw dentation that rubber sleeve 1 outer surface is uniformly distributed with protruding 5 closely cooperates with the inwall in the taper newel post hole 6 of battery cover 7, thereby reaches the purpose of sealing.When battery uses the later stage, to grow up along with what pole plate 9 made progress, rubber sleeve 1 moves on slight along taper newel post hole 6, thereby cooperates closelyr with battery cover 7 upper conical newel post holes 6, makes sealing effectiveness better.
