Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model column type battery fluid injection tool is described in further detail.
As shown in Figure 1 to Figure 3, in a preferred embodiment, column type battery fluid injection tool of the present utility model uses in battery liquid-filling process.The liquid injection port of column type battery is formed in a wherein cylindrical end of column type battery usually, is especially formed in the central axis that battery core paper and lug reel.Battery liquid-filling tool of the present utility model comprises body 3, fluid injection part 1 and an a connection piece 2.
Body is for holding and fixedly treat the column type battery 4 of fluid injection.Body 3 is roughly formed as cylindric, and its inside is formed with one first cavity, and the shape of the first cavity and size match with the shape of column type battery 4 and size treating fluid injection.First cavity depth of body 3 is less than the height of the column type battery 4 treating fluid injection, and therefore treat that a part for the column type battery 4 of fluid injection is contained in the first cavity of body 3, side is on the body 3 exposed in one end that column type battery 4 is formed with liquid injection port 41.
Fluid injection part 1 comprises end cap 11 and a sealing ring 12.End cap 11 is formed as cylindric, is formed with an opening 14 in the position that end cap 11 is connected with sealing ring 12, injects for electrolysis liquid.Opening 14 on end cap 11 is preferably conical hopper shape, and one end diameter near sealing ring 12 is less, and one end diameter away from sealing ring 12 is comparatively large, and electrolyte therefore can be made to be not easy to overflow when injecting electrolyte.Fluid injection part 1 also comprises an extension 15 extended towards the direction near connector 2 from the opening 14 of end cap 11, extension 15 is formed as stepped hollow cylindrical, extension 15 is comparatively large near the drum diameter of end cap 11, and the drum diameter away from end cap 11 is less.Sealing ring 12 is arranged on fluid injection part 1 away from the form of one end of end cap 11 to surround extension 15.Sealing ring 12 matches with the inner periphery of liquid injection port 41 of the column type battery 4 treating fluid injection.In a preferred embodiment, the inner periphery equal diameters of the diameter of sealing ring 12 and the liquid injection port 41 of column type battery 4.In an additional preferred embodiment, the diameter of sealing ring 12 is slightly larger than the inner periphery diameter of the liquid injection port 41 of column type battery 4, and therefore sealing ring 12 forms interference fit, better tightness with the liquid injection port 41 of column type battery 4.
Fluid injection part 1 is connected by above-mentioned connector 2 with body 3.Connector 2 is formed as cylindric, and fluid injection part 1 and connector 2 removably connect.In a preferred embodiment, the end cap 11 of fluid injection part 1 is formed with screwed hole 13, connector 2 position corresponding with the screwed hole 13 of end cap 11 is also formed with screwed hole 22, countersunk head screw 6 continues across end cap 11 upper screwed hole 22 after the screwed hole 22 of connector 2 passes, thus connector 2 and fluid injection part 1 is removably fixed together by countersunk head screw 6.
Also formed between connector 2 and body 3 and removably connect.In a preferred embodiment, the centre of connector 2 is formed with one second cavity 23, second cavity 23 and is formed with internal thread 21.The outside of body 3 is formed with the external screw thread 31 matched with the internal thread 21 of the second cavity 23 of connector 2.By body 3 is screwed in connector 2, body 3 is formed with connector 2 and is removably fixedly connected with.
During column type battery fluid injection tool work of the present utility model, first will treat that column type battery 4 fixed placement of fluid injection is in the first cavity of body 3, make to treat that the column type battery 4 of fluid injection is formed with liquid injection port 41 one end towards the direction away from body 3; Connector 2 and fluid injection part 1 are fixed by countersunk head screw 6, makes sealing ring 12 stretch in the second cavity 23 of connector 2; Need the body 3 of fluid injection column type battery 4 rotate in the second cavity 23 of connector 2 by loading, one end that the one end making battery 4 be formed with liquid injection port 41 is stretched in the second cavity 23 of connector 2 or battery is formed with liquid injection port 41 in another embodiment stretches in end cap 11 opening 14 of fluid injection part 1, and make the sealing ring 12 of fluid injection part 1 be pressed into the inner periphery of the liquid injection port 41 of battery, preferably the diameter of sealing ring 12 is slightly larger than the inner periphery diameter of battery liquid-filling mouth 41, sealing ring 12 and battery liquid-filling mouth 41 is made to form interference fit, enhanced leaktightness; Finally by fluid injection instrument, electrolyte is injected from the opening 14 of the end cap 11 of fluid injection part 1 liquid injection port 41 treating fluid injection column type battery.Because the inner periphery of sealing ring and battery liquid-filling mouth is tightly connected, the opening of fluid injection part, namely liquid injection port is directly connected to the liquid injection hole of battery, there will not be the phenomenon of leakage, can not pollute other positions of battery core, improve finished battery rate when therefore electrolyte injects.
Although carry out in conjunction with above specific embodiment description of the present utility model, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
