Embodiment
Core of the present utility model is to provide a kind of alkaline battery sealing ring, can improve the sealing of sealing ring, prevents battery leakage.
In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of alkaline battery partial structurtes in prior art, Fig. 2 is the structural representation of a kind of embodiment neutral and alkali battery seal ring provided by the utility model, and Fig. 3 is the assembling schematic diagram of alkaline battery sealing ring shown in Figure 2.
In this embodiment,, for the ease of the sealing ring body is described, adopted a kind of assembling mode of sealing ring with this, sealing ring body to be described.
At the bottom of the negative pole that alkaline battery comprises shell 11, connect with sealing ring body 12 13 and the sealing ring body 12 that is provided with nearly negative pole bottom 15 and negative pole bottom 16 far away, the outside of the transition face that nearly negative pole bottom 15 and negative pole bottom far away are 16 is the angled transition face, shell 11 is provided with groove 14, angled transition face and groove 14 bottom end faces connect, and the bottom end face of groove 14 refers to the end face of the ledge that groove 14 caves inward.
So arrange, nearly negative pole bottom 15 is the angled transition face with the transition face of negative pole bottom 16 far away, and the bottom end face of groove 14 and angled transition face connect.with transition face shown in Fig. 1 be horizontal transition face 06, arc groove 03 plays spacing and effect support level transition face 06, undesirable the comparing of sealing effectiveness that causes 01, sealing ring 02 and shell, in the present embodiment as shown in Figure 2, because transition face is the angled transition face, at the bottom of sealing ring body 12 is subject to from negative pole during 13 pressure, the bottom end face of angled transition face and groove 14 power that can be squeezed at the contacting points position place, the angled transition face has the trend of along the pressure direction, moving, and then the tightness of increase angled transition face and groove 14, therefore can improve the sealing of sealing ring body 12 and shell 11, prevent the alkaline battery leakage.
Need to prove, sealing ring body 12 is sealed nylon circle body in this embodiment, certainly, when guaranteeing the alkaline battery sealing effectiveness, does not also get rid of the sealing ring that uses other materials, as PP material seal circle (polypropylene material sealing ring).
In addition, sealing ring body 12 also comprises the center pillar 19 that is provided with installing hole, and the collector electrode 110 of alkaline battery is placed in installing hole, and the end face of the top of collector electrode 110 and center pillar 19 connects.
In order to enlarge sealing ring body 12 and 13 contact area at the bottom of negative pole and to improve the rigidity of sealing ring body 12, sealing ring body 12 also is provided with and the 13 a spares that connect 17 and b spare 18 at the bottom of negative pole, and a spare 17 is arranged at the position of sealing ring body 12 near center pillars 19; B spare 18 is arranged at the inboard of angled transition face.
in the middle of prior art, a spare 17 and b spare 18 positions are groove, the profile of a spare 17 and b spare 18 respectively with the profile of position groove and measure-alike, by a spare 17 and b spare 18, groove is filled, can increase the rigidity of sealing ring body 12, simultaneously, due to a spare 17, b spare 18 connects with 13 end face at the bottom of negative pole respectively, sealing ring body 12 and 13 contact area at the bottom of negative pole have been enlarged, guarantee that the inner surface of nearly negative pole end 15 and the distance L of b spare 18 inner surfaces maintain 0.8-1.0mm, thereby improved at the bottom of negative pole 13 and the sealing of 12 of sealing ring bodies.
Need to prove, refer to the side that the groove 14 with shell 11 connects in the outside of this embodiment medium dip transition face, opposite side is the inboard of angled transition face.
Also need to prove, in this embodiment, a spare 17 and b spare 18 are the integral type setting, a spare 17, b spare 18 and sealing ring body 12 can certainly be set to integral type.
What also need to further illustrate is, sealing ring body 12 is provided with explosion-proof ditch 111 near the end of center pillar 11, in order to guarantee that explosion-proof ditch 111 can proper function, those skilled in the art should clearly know, a spare 17 should be groove part with the space that center pillar 19 surrounds, and this groove part is placed in the top of explosion-proof ditch 111 positions.In this embodiment, a spare 17 is the cylinder shape groove part with the space that center pillar 19 surrounds, and this cylinder shape groove partly is placed in the top of explosion-proof ditch 111 positions.
In further scheme, in order to enlarge the volume of battery electrolyte, the end face that the top of center pillar 19 and collector electrode 110 connects is a little more than the end face of nearly negative pole bottom 15.
As shown in Figure 1, in the prior art, the top end face of center pillar 07 is lower than the end face of nearly negative pole bottom 05, cause the bottom of center pillar 07 to be inserted in the cavity of alkaline battery, this cavity is used for holding the electrolyte of alkaline battery, center pillar 07 part that is placed in cavity has just taken certain volume like this, causes the volume that can hold electrolyte to reduce.
As shown in Figure 2, in the situation that keep constant with middle column length, in this embodiment with center pillar 19 near 13 direction at the bottom of negative pole, moving, make end face that the top of center pillar 19 and collector electrode 110 the connects end face higher than nearly negative pole bottom 15, so,, in the situation that the cavity volume of alkaline battery is constant, is placed in the volume of alkaline battery cavity by reducing center pillar 19, and then has enlarged cavity and can hold the volume of electrolyte.
Need that bright is, although the end face that center pillar 19 and collector electrode 110 connect is higher than the end face of nearly negative pole bottom 15, center pillar 19 is relevant with 13 depth of inner cavity at the bottom of negative pole along the distance that moves near 13 direction at the bottom of negative pole, but can guarantee collector electrode 110 with at the bottom of negative pole 13 can normally coordinate, guarantee the sealing of alkaline battery, can prevent the phenomenon of leakage.
Certainly, center pillar 19 is when moving near 13 direction at the bottom of negative pole, also can make end face that center pillar 19 and collector electrode 110 connect mutually concordant with the end face of near negative pole bottom 15.
In scheme further, for the ease of sealing ring body 12 is installed, negative pole bottom 16 far away is tapered distal negative pole bottom, it is along top to the direction convergent of bottom, the bottom of tapered distal negative pole bottom refers to the end relative with the cavity that holds electrolyte of alkaline battery, and top refers to the end that is connected with the angled transition face.
Above a kind of alkaline battery sealing ring provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
