Abstract
The invention provides a sealing structure of an end post and a battery cover of a lead-acid storage battery. The sealing structure provided by the invention mainly comprises the end post of the battery, a soft rubber sleeve and the battery cover, wherein the end post is composed of a lead post and an interior copper core; the periphery of the lead post is provided with the soft rubber sleeve, the inner surface of the soft rubber sleeve and the periphery of the lead post are correspondingly provided with mazy concave-convex structures, and the outer surface of the soft rubber sleeve is of a conical structure; and annular zigzag bulges are arranged along a conical surface, and the outer surface of the soft rubber sleeve is in close fit with the inner wall of a conical end post hole, which has the same conical degree with the outer surface of the soft rubber sleeve, on the battery cover. The sealing structure provided by the invention has the beneficial effects that the mazy concave-convex structure at the inner surface of the soft rubber sleeve can be used for enhancing the bonding force of the soft rubber sleeve and the lead post and simultaneously prolonging the distance of an electrolyte penetrating into the upper part of the end post of the battery along the lead post; the annular zigzag bulges uniformly distributed at the outer surface can achieve a multi-linear seal effect and ensure the reliability; and the soft rubber sleeve grows upward along with a pole plate and moves upward slightly, thus the soft rubber sleeve is in close fit with the conical end post hole and the seal effect is better.
Description
Technical field
The present invention 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, tight contact by 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 is subjected to external force to make the easy excessive sour hidden danger of contact-making surface appearance of destroying of time spent; Along with use the later stage pole plate upward to grow up, rubber sleeve moves on easily, destroys integral sealing effect.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 of lead block and inner copper core, 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 mazy concaveconvex structure, the outer surface of soft gum cover is a pyramidal structure, and along the conical surface zigzag projection of annular is arranged, soft gum cover outer surface with closely cooperate with the battery cover taper newel post hole inwall of tapering.
Described soft balsam cover material is the acid-resistant, thermoplastic soft rubber, is socketed in the periphery of lead block.
Described 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 projection 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 invention has the beneficial effects as follows: the labyrinth type 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 projection of the annular that soft gum cover outer surface is uniform 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
Figure one is for having the battery newel post cutaway view Amplified image of rubber sleeve in the embodiment of the invention;
Figure two is a battery cover partial sectional view of the present invention;
Figure three is a part assembling diagrammatic cross-sectional view of the present invention.
Among the figure, 1. rubber sleeve, 2. lead block, 3. copper core, 4. concaveconvex structure, 5. zigzag projection, 6. taper newel post hole, 7. battery cover, 8. battery case, 9. pole plate.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
As shown in Figure 1, 2, 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 of lead block 2 and inner copper core 3, rubber sleeve 1 is directly injection-moulded in lead block 2 peripheries, 2 rubber sleeves, 1 inner surface and lead block 2 periphery correspondences are provided with mazy concaveconvex structure 4, the outer surface of rubber sleeve 1 is a pyramidal structure, and along the conical surface zigzag projection 5 of annular is arranged, rubber sleeve 1 outer surface with closely cooperate with battery cover 7 taper newel post hole 6 inwalls of 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 inwall in the band saw dentation projection 5 that rubber sleeve 1 outer surface is uniform and the taper newel post hole 6 of battery cover 7 closely cooperates, thereby reaches the purpose of sealing.When battery uses the later stage, along with growing up that pole plate 9 makes 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.
