Abstract
The utility model discloses a pole column sealing structure with unscrewing sealing caps. The pole column sealing structure comprises pole columns inserted in middle cover pile column holes and sealing glue of the sealing pole columns. The periphery of the sealing glue is coated with the sealing caps, and a plurality of isometric force arm rib strips are arranged on the outer side walls of the sealing caps. The pole column sealing structure is simple in structure, the pole columns are arranged in the pole column hole sealing caps from the reserve sides, when a middle cover is sealed, the middle cover sealing glue is filled into the pole column hole sealing caps, after the sealing glue is solidified, the top end portions of the sealing caps are unscrewed from the front side, the top ends of the pole columns are exposed out, the operation is convenient and rapid, the pole columns are good in sealing effect, an existing cutter is prevented from being used for milling, gaps, namely the capillarity phenomenon, formed between the pole columns and the sealing glue, are caused by the vibration in the washing and cutting processes, the production efficiency and the product quality are improved, extra devices are not required, and the production cost is saved.
Description
Technical field
the utility model relates to battery technology field, is specifically related to a kind of sealing cap and can twists formula post sealing structure.
Background technology
Storage battery is in manufacture process, especially in assembling, compress in electrode column sealing circle operation, manual operation is unstable, fluctuation is large, often occur that the sealing ring pressure in pole column hole is not in place, or weigh sealing ring wounded, in later stage use, be prone to because of the not good pole that causes of pole column hole sealing and climb sour phenomenon, affect storage battery quality.In order to address this problem, a lot of improvement have been done by manufacturer, as an electrode column sealing cap is set in terminal groove, pole is placed in pole column hole sealing cap from the negative, during involution middle cover, in pole column hole sealing cap, stamp capping glue, after glue is dry, from front by CNC milling machine, sealing cap head portion is washed off, expose pole and then weld.But such operation also has a lot of defects, the vibrations of cutter in washing the process of cutting can cause between pole and fluid sealant and produce gap, be capillarity, experimental results show that terminal leaks sour risk still larger, and this structure need supporting numerical control device in production process.For this reason, a kind of better structure of demand is extremely urgent.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of sealing cap can twist formula post sealing structure, sealing is simple in structure, without dropping into other equipment, directly with instrument, twist off the sealing cap on pole, expose the plumbous boss of pole, convenient to operation, electrode column sealing is effective, has improved the quality of production efficiency and product.
The utility model is achieved through the following technical solutions:
Can twist a formula post sealing structure, comprise the pole being inserted in middle cover pole column hole and the fluid sealant that seals pole, described fluid sealant periphery is coated with sealing cap, and sealing cap lateral wall arranges some contour arm of force ribs.
The further improvement project of the utility model is that described sealing cap from bottom to top diameter diminishes gradually, is circular cone stage body.
The utility model further improvement project is, described sealing cap lateral wall is 3～5 ° to downward-extension outer dip angle, and sealing cap madial wall is 13～28 ° to downward-extension outer dip angle.
The utility model further improvement project is that described arm of force rib is 2-8 bar, along sealing cap lateral wall isogonism, arranges.
The utility model further improvement project is, the wide 0.5-3mm of described arm of force rib, thick 0.5-2mm.
The utility model further improvement project is, described sealing cap madial wall top arranges some convex ribs, and convex rib wraps in fluid sealant.Convex rib pole is between two parties set, can also squeeze a part of fluid sealant, reduce the intensity of sealing cap top seal glue, be convenient to twist off sealing cap.
The utility model further improvement project is that described convex rib is arranged along sealing cap madial wall isogonism.
The long 2-4mm of described convex rib, wide 0.3-0.9mm, thick 0.4-1mm.
The utility model further improvement project is, described pole top is less than 0.5mm to the distance of sealing cap top inner wall, and the convex rib extremely distance between post is 0.5～0.8mm, is filled with fluid sealant therebetween.
The utility model further improvement project is, described pole from bottom to top diameter diminishes gradually, is circular cone stage body, and its lateral wall is 3～8 ° to downward-extension outer dip angle.
The utility model compared with prior art, has following obvious advantage:
The utility model type is simple in structure, pole is placed in pole column hole sealing cap from the negative, during involution middle cover, in pole column hole sealing cap, stamp capping fluid sealant, after gelling to be sealed is solid, from front, twist off sealing cap head portion, expose pole top, convenient to operation, electrode column sealing is effective, has avoided the milling of original use cutter, washes vibrations in the process of cutting and causes between pole and fluid sealant and produce gap, be capillarity, improved the quality of production efficiency and product, and without extra used device, saved production cost.
