The pollution of electrolyte, if while temperature is excessively high when causing battery internal combustion, be easy to happen explosion or fire, life security caused
It threatens.
Utility model content
The purpose of this utility model is to provide a kind of battery cap component, which is equipped with liquid injection hole, note
Fluid apertures is the stepped hole that top opening diameter is greater than base opening diameter, and in fluid injection, the bottom nozzle and liquid injecting mouth of liquid injection hole are in close contact, benefit
In fluid injection, while liquid injection hole top ports do not contact liquid injecting mouth, prevent the pollution of electrolyte, have to liquid injection hole sealing nail welding excellent rate
Very big improvement, while explosion-proof valve is equipped on top cover, when internal combustion occurs for battery, pressure increases, and passes through explosion-proof valve explosion in time
Exhaust, plays the role of safeguard protection, and gas leak phenomenon is not had before explosion.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of battery cap component, including coping plate, the surface of coping plate be respectively arranged on the left side and the right side minus thread pole and
Plus thread pole；
The surface of coping plate is located at minus thread pole side equipped with explosion-proof valve；
The surface of coping plate is equipped with liquid injection hole between explosion-proof valve and plus thread pole, and liquid injection hole is bench port, fluid injection
The top ports diameter in hole is 3-5 times of bottom nozzle diameter, and interference fit is equipped with sealant nail in liquid injection hole；
It is fixed at left and right sides of the bottom surface of coping plate that there are two the ceiling holds being oppositely arranged.
Further, minus thread pole and plus thread pole are fixed on coping plate using rubber encapsulated form, and
Built-in sealing ring.
Further, sealant nail include sealing column and block machine, sealing column be circular cone structure and with liquid injection hole interference
Cooperation.
Further, ceiling hold is plastic parts, and two plastic parts are mechanically anchored in the bottom surface of coping plate.
The utility model has the beneficial effects that
1, the battery cap component of the utility model is equipped with liquid injection hole, and liquid injection hole is the platform that top opening diameter is greater than base opening diameter
Rank hole, in fluid injection, the bottom nozzle and liquid injecting mouth of liquid injection hole are in close contact, and are conducive to fluid injection, while liquid injection hole top ports do not contact
Liquid injecting mouth prevents the pollution of electrolyte, is greatly improved to liquid injection hole sealing nail welding excellent rate.
2, the utility model is equipped with explosion-proof valve on top cover, and when internal combustion occurs for battery, pressure increases, in time by explosion-proof
Valve explosion exhaust, plays the role of safeguard protection, and gas leak phenomenon is not had before explosion.
3, the plastic parts ceiling hold that the utility model is arranged in the bottom surface of coping plate, is distinguished admittedly using two plastic parts machinery
In the injection molding directly on coping plate, deformation is big, and directly fixed plastic parts deformation of timbering is small, can to avoid naked cell polar ear and
Aluminum hull contact, occurs internal short-circuit.
