Abstract
The utility model discloses a secondary cell utmost point post seal structure, including cylindrical rubber pads, the central mounting hole diameter of cylindrical rubber pads and secondary cell's utmost point column diameter phase -match, the lower half cover of cylindrical rubber pads have an inner wall and the subsides of rubber bag pad outer wall tightly, bottom surface and the tight steel bowl of rubber pad terminal surface subsides. Steel bowl's the inner wall and the lower half outer wall joint portion of cylindrical rubber pad are the shape of carving of mutual correspondence. The utility model discloses closely cooperate with steel bowl and cylindrical rubber pads, can seal up simultaneously from axial and terminal surface during the installation of utmost point post, put forward the high leakproofness ability, assurance product quality.
Description
Technical field:
This utility model relates to the post sealing structure of accumulator, has axially and effect that end face seals simultaneously, raising airtight quality.
Background technology:
The sealing structure of existing secondary battery anode and cathode post, is all to use O-ring seals.When accumulator assembling seals, sealing ring compresses not tight because compression reduces, poorly sealed, causes and then causes deformation to follow the string when climbing alkali, leakage, sealing ring compression tension, and result causes poorly sealed, affects product quality.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, can make axially simultaneously sealing with end face of pole, improve the secondary cell post column sealing arrangement of airtight quality.
The technical solution of the utility model completes as follows, a kind of secondary cell post column sealing arrangement, including a tubular rubber blanket, it is characterized in that: the center mounting hole diameter of tubular rubber blanket matches with the pole diameter of secondary cell, be cased with an inwall and the steel bowl that rubber bag pad outer wall is adjacent to, bottom surface is adjacent to rubber blanket end face in the lower half of tubular rubber blanket.The inwall of steel bowl and the outer wall joint portion, lower half of tubular rubber blanket are in the most corresponding wedge.
This utility model steel bowl closely cooperates with tubular rubber blanket, can improve sealing property, it is ensured that product quality from axially sealing with end face simultaneously when pole is installed.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing, this utility model includes a tubular rubber blanket 1, center mounting hole 3 diameter of tubular rubber blanket matches with the pole diameter of secondary cell, is cased with an inwall and the steel bowl 2 that rubber bag pad outer wall is adjacent to, bottom surface is adjacent to rubber blanket end face in the lower half of tubular rubber blanket.The inwall of steel bowl and the outer wall joint portion, lower half of tubular rubber blanket are in the most corresponding wedge.During installation, pole outer end tight fit is inserted in the installing hole of rubber blanket, then steel bowl is locked is fixed on the outer wall of rubber blanket.When the most firmly compressing rubber blanket, rubber blanket axially can pressed the tightest, make the most well to be sealed, and laterally owing to having steel bowl and pole rigid contact, rubber blanket cannot can only extend to end face to extending around, make end face well be sealed, the height of steel bowl can efficiently control compression ratio, overcomes the various defects of wobble seal.
Claims (2)
1. a secondary cell post column sealing arrangement, including a tubular rubber blanket, it is characterized in that: the center mounting hole diameter of tubular rubber blanket matches with the pole diameter of secondary cell, be cased with an inwall and the steel bowl that rubber bag pad outer wall is adjacent to, bottom surface is adjacent to rubber blanket end face in the lower half of tubular rubber blanket.
A kind of secondary cell post column sealing arrangement the most according to claim 1, it is characterised in that: the inwall of steel bowl and the outer wall joint portion, lower half of tubular rubber blanket are in the most corresponding wedge.
