Description
Technical field
It the utility model is related to a kind of field of batteries, and in particular to a kind of battery seal ring.
Background technology
In general battery is designed with anti-explosion mechanism, and anti-explosion mechanism includes being located at the explosionproof hole at battery upper shell, explosionproof hole
Interior to be provided with explosion-proof pin and rupture pressure disc, rupture pressure disc is located at the lower section of explosion-proof pin, when the air pressure in battery is too high, can make rupture pressure disc
Deforming contact, so as to cause rupture pressure disc to rupture, makes the gas overflowing of inside battery to the tip of explosion-proof pin.
The sealing ring of general battery, is arranged on the collector sealing end in battery, the resistance to leakage to battery electrolyte, has
Decisive role.Especially with the development of battery technology, become greatly for effective volume to increase inside battery active material
Amount, to improve the scheme of the performance of battery and capacity, be increasingly taken seriously.
Utility model content
The purpose of this utility model is to be directed to above mentioned problem existing for existing technology, there is provided it is fixed that one kind can play support
Position and the battery seal ring of sealing function.
To achieve these goals, technical scheme provided by the utility model is：
A kind of battery seal ring, battery is by core bag and is connected in core and wraps the upper lid in portion and forms, and lid is just provided with upper lid
Body, upper lid has the explosionproof hole with being communicated inside core bag, the sealing ring made of elastomeric material is provided with explosionproof hole, described
The explosion-proof pin for being coaxial therewith the heart is provided with sealing ring, sealing ring sidepiece has the sealing contacted with explosionproof hole inner wall sealing.
Specifically, it is provided with screwed hole on the sealing ring.
Specifically, the explosion-proof pin top is provided with the screw thread being threadedly coupled with the screwed hole on sealing ring.
Specifically, the lid is connected by screw with upper lid.
Compared with prior art, the beneficial effects of the utility model are：
The utility model, it is simple in construction, the distance between explosion-proof pin and rupture pressure disc can be adjusted by rotating explosion-proof pin
So as to change the atmospheric pressure value of inside battery, suitable for the battery without explosion-proof degree, while installation steps are simplified, improve effect
Rate.
Brief description of the drawings
Fig. 1 is the assembling structure schematic diagram in battery anti-explosion hole.
Fig. 2 is the structural representation of sealing ring.
Parts title in accompanying drawing is：
1st, upper lid, 2, lid, 3, sealing ring, 4, electrolyte, 5, rupture pressure disc, 6, explosion-proof pin, 7, explosionproof hole, 8, screwed hole.
Embodiment
As shown in Figure 1, 2, a kind of battery seal ring, battery is by core bag and is connected in core and wraps the upper lid 1 in portion and forms, upper lid
1 top is provided with lid 2, and the lid 2 is connected by screw with upper lid 1.Upper lid 1 has the explosionproof hole with being communicated inside core bag
7, sealing ring 3 made of elastomeric material are provided with explosionproof hole 7, and screwed hole 8 is provided with the sealing ring 3.Described is close
The explosion-proof pin 6 for being coaxial therewith the heart is provided with seal 3, the top of explosion-proof pin 6 is provided with and the spiral shell of screwed hole 8 on sealing ring 3
The screw thread of line connection.The sidepiece of sealing ring 3 has the sealing contacted with the inner wall sealing of explosionproof hole 7.
Sealing ring 3 is provided with explosionproof hole 7, explosion-proof pin 6 is provided with sealing ring 3, the lower section of explosion-proof pin 6 is provided with rupture pressure disc 5,
The lower section of rupture pressure disc 5 is the electrolyte 4 in core bag.When the rise of battery core air pressure inside, rupture pressure disc 5 will be made to be under pressure and produce
Deformation, with the rise of air pressure inside, after reaching certain value, cause the deformation of rupture pressure disc 5 to touch explosion-proof pin 6, make explosion-proof pin 6
Rupture pressure disc 5 is pierced through at tip, subsequent battery core internal gas, by the rupture pressure disc 5 being pierced, releases battery, is prevented with reaching
The purpose of battery explosion.Explosion-proof pin 6 is set in sealing ring 3, prevents the electrolyte 4 in battery from corroding the screw thread on explosion-proof pin 6.
In the assembling process of battery, explosion-proof pin 6 is put into explosionproof hole 7 simultaneously with sealing ring 3, improves installation effectiveness.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
