Abstract
The utility model discloses a kind of battery cap sealing ring, particularly relate to lithium battery combination cover cap sealing ring, belong to accessory battery field.Described lithium battery combination cover cap sealing ring is hollow ring body, comprises circle body, upper edge and lower edge, it is characterized in that, along the resistance material muscle of seal inwall one week wedge type.Sealing ring energy limiter assembly height after improvement, effectively prevents the many dresses of assembly or fills problem less, improves assembling quality; Material thickness just in time fills up the spacing of resistance material muscle apart from sealing ring inner bottom part, is stuck within sealing ring firmly by combination material, avoids the material caused because of reasons such as vibration, extruding and reverse placements well and comes off.
Description
Technical field
The utility model relates to a kind of battery cap sealing ring, particularly relates to lithium battery combination cover cap sealing ring, belongs to accessory battery field.
Background technology
The life appearing as we mankind of battery, amusement and work provide important power supply guarantee.Along with the development of society and the progress of human civilization, primary cell due to the pollution to environment, capacity is low, service time is short etc., and shortcoming will be eliminated gradually, the substitute is the secondary cell of the advantages such as pollution-free, capacity is large, long service life, wherein the distinctive self structure of lithium battery and performance are widely applied to every field, are exactly representative wherein as notebook computer, portable power source, electric tool etc.
Security combination block is one of important parts of lithium battery.Wherein the structure of sealing ring itself not only affects the sealing effectiveness of battery, but also affects the manufacturing cost of cell production companies.The subject matter of current existence is embodied in following 2 points:
1, many dresses, the less dress of security combination block combination material directly can affect the performance of battery, and it is to scrapping, bad quantification.
2, due to the reason such as vibrated, extrude and oppositely places after traditional sealing ring and combination material combine, material is easy to come off, rework rate greatly, operating efficiency reduction, virtually add manufacturing cost.
Summary of the invention
The utility model is easily expected to come off for cover cap combination thing and is filled more, fills this phenomenon less, develops a kind of sealing ring, stops coming off of material, effectively prevents the many dresses of material, few dress.
For realizing the utility model object, according to the reason of de-material be combined on the basis of sealing ring inner part gross thickness size, the interior wall construction of its sealing ring.Technical solution is as follows:
Described lithium battery combination cover cap sealing ring is hollow ring body, comprises circle body, upper edge and lower edge, it is characterized in that, within one week, be provided with the resistance material muscle of wedge type along sealing ring inwall.
Resistance material muscle position is preferred: along 1.1 millimeters of places under sealing ring.
One-body molded by grinding tool.
The utility model advantage: because sealing ring inwall is provided with the resistance material muscle of wedge type, energetic, limiter assembly height, when wherein any one combines material to many dresses, its resistance material muscle will be coated over below material, obviously can't see resistance material muscle, with the naked eye just can check out block many dresses problem intuitively.When otherwise material fills less, resistance material muscle can not be filled up apart from the distance between sealing ring inner bottom part, effectively prevent the problem of few dress, improve block assembling quality; And combination material has obvious pause and transition in rhythm or melody sense when pressing in sealing ring, and material thickness just in time fills up the spacing of resistance material muscle apart from sealing ring inner bottom part, firmly combination material is stuck within sealing ring, though be no matter be subject to vibrating, the stacking in extruding and level direction, its material all can not come off.Avoid well because vibration, extruding and material that oppositely reason such as placement causes come off.Easy to use, successful.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1
As shown in Figure 1, lithium battery combination cover cap sealing ring described in the utility model is hollow ring body, comprises circle body, upper edge and lower edge, it is characterized in that, within one week, is provided with the resistance material muscle 1 of wide 0.5 millimeter, high 0.2 millimeter of wedge type along sealing ring inwall.Resistance material muscle 1 under sealing ring along 1.1 millimeters of places.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection range of the present utility model.
Claims (2)
