Abstract
The invention discloses a battery sealing ring structure which comprises a bottom plate (1), wherein a bulge (2) with a through hole is arranged in the middle of the bottom plate (1), a first folding edge (3) extending towards the middle is arranged at the upper end of the bulge (2), a cavity (4) is formed between the first folding edge (3) and the bulge (2), a second folding edge (5) is arranged on the outer peripheral wall of the bottom plate (1), and the second folding edge (5) and the bulge (2) are positioned on the same side of the bottom plate (1); the invention effectively increases the capacity of the air chamber in the battery, further avoids the phenomenon of air inflation or bursting of the battery and improves the safety.
Description
Technical field
The present invention relates to cell art, a kind of cell sealing coil structures are specifically referred to.
Background technology
Common batteries refer to just extremely manganese dioxide, and negative pole is the zinc cylinder of zinc punching, the electrolyte being made up of zinc chloride-ammonium chloride-water, the device for chemical energy to be converted into electric energy, and it is widely used in the life of people.Inside battery is often provided with air chamber, and air chamber is generally located between battery core and sealing ring, the Main Function of air chamber is to accommodate the gas produced when battery storing and electric discharge, and the gas produced during to battery storing and electric discharge plays a part of compensator or trimmer pressure, it is to avoid inflatable or Decrepitation Phenomena occurs in battery.But the air chamber inside current battery is limited because of structure(The bottom of sealing ring is tabular), its capacity is typically small, when the gas that such as battery is produced in storage and electric discharge is excessive, can equally cause the appearance of battery inflatable or Decrepitation Phenomena, there is very big danger.
The content of the invention
The technical problem to be solved in the present invention, is to provide a kind of cell sealing coil structures that can increase inside battery air chamber.
To solve above-mentioned technical problem, the invention provides a kind of cell sealing coil structures of following structure, including base plate, base plate middle part is provided with the projection with through hole, raised upper end sets the first flanging that oriented middle part extends, cavity is formed between first flanging and projection, base plate periphery wall is provided with the second flanging, the second flanging and the raised homonymy positioned at base plate;By the setting of cavity, the bottom of original sealing ring is changed for flat structure, increase effectively the capacity of inside battery air chamber, further avoid the appearance of battery inflatable or Decrepitation Phenomena, improve security.
Cell sealing coil structures of the invention, wherein, the 3rd flanging is provided with the first flanging, the 3rd flanging is set towards base plate;By the setting of the 3rd flanging, when carbon-point is plugged in sealing ring, the contact area of carbon-point and sealing ring can be increased, improve the support strength to carbon-point.
Cell sealing coil structures of the invention, wherein, the 3rd flanging inner wall lower is provided with the arcwall face of indent;Arcwall face is set by the 3rd flanging inner wall lower, when in carbon-point insertion sealing ring, guide effect can be played to carbon-point, brought conveniently to assembling.
Cell sealing coil structures of the invention, wherein, the outer wall of the second flanging from top to bottom gradually forms inclined-plane to contract;By the setting of the second flanging outer wall ramp, when sealing ring and zinc cylinder are assembled, guide effect can be played to zinc cylinder, be brought conveniently to assembling, while the cooperation intensity with zinc cylinder can be increased again.
After using said structure, compared with prior art, the present invention has advantages below:1st, by the setting of cavity, the bottom of original sealing ring is changed for flat structure, increase effectively the capacity of inside battery air chamber, further avoid the appearance of battery inflatable or Decrepitation Phenomena, improve security;2nd, by the setting of the 3rd flanging, when carbon-point is plugged in sealing ring, the contact area of carbon-point and sealing ring can be increased, improves the support strength to carbon-point;3rd, arcwall face is set by the 3rd flanging inner wall lower, when in carbon-point insertion sealing ring, guide effect can be played to carbon-point, brought conveniently to assembling;4th, by the setting of the second flanging outer wall ramp, when sealing ring and zinc cylinder are assembled, guide effect can be played to zinc cylinder, is brought conveniently to assembling, while again can be by increasing the cooperation intensity with zinc cylinder, to increase the sealing of battery.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, in this specific embodiment, cell sealing coil structures of the invention, including base plate 1, the middle part of base plate 1 is provided with through hole raised 2, raised 2 upper ends set the first flanging 3 that oriented middle part extends, cavity 4 is formed between first flanging 3 and raised 2, the periphery wall of base plate 1 is provided with the second flanging 5, second flanging 5 and projection 2 are located at the homonymy of base plate 1, the 3rd flanging 6 is provided with first flanging 3, 3rd flanging 6 is set towards base plate 1, the inner wall lower of 3rd flanging 6 is provided with the arcwall face 7 of indent, the outer wall of the second flanging 5 from top to bottom gradually forms inclined-plane 8 to contract.
Embodiment above is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; on the premise of design spirit of the present invention is not departed from; various modifications and improvement that those skilled in the art make to technical scheme, all should fall into the protection domain of claims of the present invention determination.
