Abstract
The utility model discloses a compound sealing device of a battery electrode column, belonging to the field of sealing a battery electrode column with a steel shell. The compound sealing device comprises a sealing ring which is arranged between an upper cover and an electrode column, and is characterized in that the sealing ring comprises an inner ring, a middle ring and an outer ring, wherein the inner ring, the middle ring and the outer ring are sheathed on the electrode column concentrically; and the middle ring is internally provided with the inner ring and is externally provided with the outer ring made of steel. The compound sealing device is formed by the outer ring, the middle ring and the inner ring; and the inner ring is made of soft rubber materials, the middle ring is made of rigid polysulfone materials, and the outer ring is made of stainless steel materials, therefore, the sealing effect of the device is improved, and compared with the existing sealing device, the sealing device is higher in intensity and better in sealing effect.
Description
Technical field
The utility model provides a kind of battery electrode column composite seal device, belongs to box hat battery electrode column sealing field.
Background technology
In the existing technology, the sealing of box hat electrokinetic cell pole is made up of cell cover, insulation cushion, sealing ring and pole.Ring set is on pole, and loam cake is arranged between sealing ring and the insulation cushion, and fixes by nut.This device only has a sealing ring 1 (material is a polysulfones), and material is harder, and sealing effectiveness is bad, the phenomenon of leakage often occurs, and sealing ring is easily by pressure break.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is a more reliable battery pole composite seal device of a kind of sealing effectiveness of design.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of battery electrode column composite seal device, comprise the sealing ring that is arranged between loam cake and the pole, it is characterized in that: described sealing ring comprises inner ring, centre circle and outer ring, inner ring, centre circle and outer ring concentric locking collar are contained on the pole, centre circle inside is provided with inner ring, centre circle outer setting steel outer ring.
During use, cell cover is clamped by sealing ring and insulation cushion, fixes by pole and nut then.The composite seal circle improves sealing effectiveness.
Wherein preferred version is:
Described inner ring is soft viton seal ring, and is inboard near being sleeved on the pole.Inner ring is squeezed and can tricklely be out of shape, and crams space between inner ring and the pole and the space between inner ring and the centre circle.
Described centre circle is rigid polysulfone material, and centre circle is provided with faulting of slab ends.Can better adapt to pole.
The beneficial effect that the utility model battery electrode column composite seal device is had is: by adopt by outer, in, the composite seal device formed of inner ring, inner ring adopts the soft rubber material, centre circle adopts rigid polysulfone material, stainless steel material is adopted in the outer ring, improved sealing effectiveness, higher than original sealing device intensity, sealing effectiveness is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, inner ring 2, centre circle 3, outer ring 4, pole 5, insulation cushion 6, loam cake.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, apparatus for sealing pole post comprises inner ring 1, centre circle 2, outer ring 3, pole 4, insulation cushion 5, loam cake 6 compositions such as grade.Inner ring 1, centre circle 2 and outer ring 3 concentric locking collars are contained on the pole 4, and centre circle 2 inside are provided with inner ring 1, centre circle 2 outer setting steel outer rings 3.Inner ring 1 is soft viton seal ring, and is inboard near being sleeved on the pole 4.Inner ring 1 is received extruding and can tricklely be out of shape, and crams space between inner ring 1 and the pole 4 and the space between inner ring 1 and the centre circle 2.Centre circle 2 is rigid polysulfone material, and centre circle 2 is provided with faulting of slab ends, can better adapt to pole 4.
Operation principle and use:
During use, cell cover 6 is clamped by sealing ring and insulation cushion 5, fixes by pole 4 and nut then.Fastening nut compresses by the boss and the sealing ring inner ring 1 of insulation cushion 5 with loam cake 6, makes its overflow centre circle 2 inner chambers increase its sealing effectiveness, and centre circle 2 plays lock ring and insulation, and centre circle 2 outsides are with steel outer ring 3, to increase its intensity.
