Abstract
Basis is practical relates to a kind of lithium ion cylinder battery anti-leak fluid injection cup, and fluid injection cup comprises fluid injection cup housing 1, O shape circle 2, sealing ring 3, step 8, draw-in groove 9.Fluid injection cup need be nested into when using in the box hat 6 of band core 7, wherein box hat 6 comprises box hat faucal 4 and slot rolling position 5, O shape circle 2 coordinates with the draw-in groove 9 of fluid injection cup housing 1 and box hat faucal 4 tensioner of box hat 6 respectively, and sealing ring 3 coordinates with the step 8 of fluid injection cup housing 1 and slot rolling position 5 tensioner of box hat 6 respectively.When the utility model can avoid lithium ion cylinder battery fluid injection, the leakage of electrolyte, is simple in structure and convenient in use.
Description
Technical field
The utility model relates to a kind of lithium ion cylinder battery priming device, particularly relates to a kind of device preventing the process electrolyte leakage of lithium battery fluid injection.
Background technology
Lithium ion cylinder battery is when carrying out vacuum liquid filling, generally need to use fluid injection cup device, and the pattern of fluid injection cup is generally PVC material, with the cast cylinder of rubber o-ring, this structure effectively can not realize sealing, electrolyte can be caused to reveal, or at faucal inwall entrained electrolyte, thus add the operation of after-teeming electrolyte and clean entrained electrolyte.Battery core sealing process can destroy box hat nickel coating, and entrained electrolyte, as totally unclean, can corrode box hat, and the bad order problem causing battery core to be got rusty, does not singly reduce the competitiveness of product in market, also add the cost of labor that follow-up rust cleaning is done over again.And adopt the utility model can reduce the generation of box hat problem of rustiness.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the device that the utility model provides a kind of fluid injection leakage-preventing.
Concrete scheme of the present utility model is: it comprises fluid injection cup housing 1, O type circle 2, sealing ring 3.Wherein fluid injection cup housing 1 inside adopts inverted cone-shaped structure; The outside draw-in groove 9 of fluid injection cup housing 1 and O type circle 2 fitted seal, outer steps 8 and sealing ring 3 fitted seal.During fluid injection, O type circle 2 and box hat faucal 4 interference fit, sealing ring 3 and box hat slot rolling position 5 interference fit, reach double sealing effect, thus prevent electrolyte from revealing.
Accompanying drawing explanation
Fig. 1 is fit structure schematic diagram of the present utility model:
Wherein: 1-fluid injection cup housing, 2-O type circle, 3-sealing ring, 4-box hat faucal, 5-slot rolling position, 6-box hat, 7-core, 8-step, 9-draw-in groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structure chart of the present utility model, comprises fluid injection cup housing 1, O type circle 2, sealing ring 3.Wherein fluid injection cup housing 1 adopts the macromolecular material of corrosion-resistant and low-friction coefficient or metal to make, difficult with electrolyte generation chemical reaction, increases the service life, reduces fluid injection cup electrolyte and remain.Fluid injection cup housing 1 bottom adopts step 8 to design, and coordinates with sealing ring 3, changes the linear sealing that original and box hat are formed into face and seals, and strengthens sealing effectiveness, but should be noted that land length is unsuitable long, avoids extruding core 7; Sealing ring 3 adopts corrosion-resistant and rubber that is intermediate resilience coefficient to make, and coordinates with fluid injection cup housing 1 step 8 tensioner, simultaneously with slot rolling position 5 inwall interference fit, realizes first and seals; O type circle 2 adopts corrosion-resistant and rubber that is intermediate resilience coefficient to make, and with the outside draw-in groove 9 of fluid injection cup housing 1 and box hat faucal 4 interference fit, realizes second sealing and avoids fluid injection cup rock or topple over simultaneously.
In injection process, by the interference fit of sealing ring 3 with slot rolling position 5, and O type circle 2 realizes sealing with the interference fit of box hat faucal 4, thus reaches the object that when preventing fluid injection, electrolyte is revealed.
The leakage-preventing fluid injection cup of this lithium ion cylinder battery, has the advantage that structure is simple, easy to use and cheap.With lower cost, the effect preventing electrolyte from revealing can be played, thus reduce subsequent handling, reduce product fraction defective, reduce product cost.
