For solving the problem; the technical solution adopted in the utility model is: alkaline dry battery sealing ring; comprise body; body is disposed with newel, connecting portion, peripheral part from inside to outside; peripheral part comprises towards the seal face of inside battery, the sealing inclined-plane being positioned at outer peripheral face, connection outer peripheral face and seal face outside seal face; newel is towards styletable face centered by the end face of inside battery side; connecting portion between newel and peripheral part is provided with protection muscle, the radial distribution of protection muscle centrally post.
Further, the seal face of peripheral part is lower than newel end face, and height difference H 1 between the two, meets formula 0.1mm < H1 < 3mm.
Preferably, described height difference H 1, meets formula 0.3mm < H1 < 3mm.
Further, described newel end face center is provided with plane injecting glue groove.
Further, described plane injecting glue depth of groove H2, meets formula 0.1mm < H2 < 1mm.
Preferably, described depth H 2, meets formula 0.3mm < H2 < 0.8mm.
Further, described connecting portion comprises connecting portion main body, explosion proof window, explosion-proof line, and explosion proof window shape to be central angle be 90 degree fan-shaped, explosion proof window is connected with connecting portion main body by explosion-proof line.
Further, the quantity of muscle is protected to be 3 to 6.
Preferably, the material of described body is nylon.
The beneficial effects of the utility model are: in connecting portion main body, arrange protection muscle, improve the mechanical performance of whole sealing ring, under pressure, while connecting portion load intensity improves, the explosion-proof line short time is broken and quick pressure releasing, add the fail safe of battery, compact ring structure effectively improves the leakproof energy of alkaline dry battery; By the optimization of structure, add the internal capacity of battery, and the material consumption of sealing ring obviously reduces, be conducive to the control of product cost.
Accompanying drawing explanation
Fig. 1 is the utility model profile;
Fig. 2 is the utility model vertical view;
Fig. 3 is conventional alkaline dry cell sealing ring vertical view.
Number in figure: post centered by 1, centered by 11 styletable face, and 12 is injecting glue groove, and 2 is connecting portion, and 21 is explosion-proof line, and 22 is connecting portion main body, and 23 is explosion proof window, and 3 is peripheral part, and 31 is seal face, and 32 is outer peripheral face, and 33 is sealing inclined-plane, and 4 is protection muscle.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1 and Fig. 2; alkaline dry battery sealing ring; comprise body; body is disposed with newel 1, connecting portion 2, peripheral part 3 from inside to outside; peripheral part 3 comprises towards the seal face 31 of inside battery, the sealing inclined-plane 33 being positioned at outer peripheral face 32, connection outer peripheral face 32 and seal face 31 outside seal face 31; newel 1 is towards styletable face 11 centered by the end face of inside battery side; connecting portion 2 between newel 1 and peripheral part 3 is provided with and protects muscle 4, the radial distribution of protection muscle 4 centrally post 1.
For improving explosion-proof, the leak resistance of battery seal ring, protection muscle 4 is the reinforcement that intensity is stronger; Alkaline dry battery sealing ring material is nylon 612, and the saturated water absorption of this material is extremely low.
Consider structure and effect, the quantity 3 to 6 of protection muscle is better, the present embodiment preferably 4.Comparison diagram 2 and Fig. 3, on the connecting portion 2 of the utility model between newel 1 and peripheral part 3, centrally the radial direction of post is arranged with 4 and protects muscle 4.
Further, reduce seal face 31 height and make it lower than newel end face 11, this portion of material can be saved, reduce costs, increasing inside battery volume simultaneously.Therefore the seal face 31 of peripheral part is lower than newel end face 11, between seal face 31 and newel end face 11, height difference H 1 recommended size is: 0.1mm < H1 < 3mm, is preferably 0.3mm < H1 < 1mm.
Further, newel end face 11 center is provided with plane injecting glue groove 12.Plane injecting glue groove 12 is set and can solves the impact on the mobility in sealing ring assembling process such as wire drawing that gum-injecting port produces, be conducive to the lifting of production efficiency.Plane injecting glue groove 12 is the circular recess concentric with newel 1, and plane injecting glue groove 12 depth H 2 recommended size is 0.1mm < H2 < 1mm.Be preferably 0.3mm < H2 < 0.8mm.
