[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] Embodiment 1:

[0022] A sealing ring structure for an alkaline manganese battery refers to a sealing ring used in an alkaline manganese battery, the main components of which include a sealing ring body, the sealing ring body including a bottom ring 1 and a center column 2 formed by injection molding, the edge of the bottom ring 1 is provided with a sealing structure 13, the sealing structure 13 can be chamfered, squared, or rounded, and is used for the sealing glue 4 area. A through hole is vertically provided at the center of the center column 2. In this structure, the sealing glue 4 area is made tighter by the sealing structure 13 at the edge of the bottom ring 1. Such a design not only ensures the integrity and stability of the sealing ring, but also provides important support for the normal operation of the alkaline manganese battery.

[0023] Through the sealing ring structure described in the present application, the sealing structure 13 set up at the bottom ring 1 plays a vital role. It makes the sealing glue 4 area tighter, effectively prevents the leakage of potassium hydroxide solution, and improves the sealing performance and service life of the alkaline manganese battery. It is worth noting that the optimized design of the sealing ring structure is not only reflected in the injection molding of the bottom ring 1 and the center column 2, but also in the details, such as the reasonable setting of the sealing structure 13, the vertical arrangement of the through holes, etc. These subtle improvements have contributed to the performance improvement of the entire alkaline manganese battery.

[0024] In addition, alkaline manganese batteries, as a common type of battery, are widely used in various electronic devices, such as handheld devices, medical devices and other fields. Therefore, the stability and sealing of the sealing ring structure are particularly important. Through the technical solution disclosed in this application, the problems existing in the sealing ring structure of traditional alkaline manganese batteries can be effectively improved, and their overall performance can be improved, thereby promoting the application and development of alkaline manganese batteries in various fields.

[0025] In summary, the alkaline manganese battery sealing ring structure design provided in the present application effectively improves the sealing performance and stability of the sealing ring by optimizing the structure of the bottom ring 1 and the center column 2 and reasonably arranging details such as the sealing structure 13 and the through hole, thereby providing a reliable guarantee for the application of alkaline manganese batteries and having important engineering application and promotion significance.

[0026] The edge of the bottom ring 1 is a vertical ring 11. This structure not only makes the overall appearance more regular, but also has better processing performance and stability in actual production. The top of the vertical ring 11 is inverted near the center column 2. This design not only facilitates the assembly of the battery, but more importantly, provides key support for the sealing and stability of the battery.

[0027] On the other hand, the bottom of the vertical ring 11 is in an arc shape away from the side of the center column. The original intention of this design is to facilitate the installation of the metal cap that fixes the battery. This design takes into account the actual situation of the entire alkaline manganese battery sealing ring structure during use, thereby effectively improving the assembly efficiency and stability of the battery assembly, and laying a solid foundation for the normal operation of the battery. This design not only provides convenience for the assembly of the battery, but more importantly, it provides key support for the sealing and stability of the battery. In addition, the middle section of the bottom ring 1 is recessed downward to form a groove 12. The addition of this design detail facilitates the installation of the sealing structure 13. The setting of the groove 12 not only allows the sealing structure 13 to be more firmly fixed on the bottom ring 1, but also provides an important guarantee for the smooth progress of the subsequent process flow. This carefully designed detail highlights the pursuit of product quality and the concern for user experience, and fully demonstrates the intention and technical strength of optimizing the sealing ring structure of alkaline manganese batteries.

[0028] In summary, the vertical ring 11 edge, the inverted design, the arc bottom shape and the setting of the middle section groove 12 of the bottom ring 1 all reflect the innovation and practicality of the present application in the structural design of the sealing ring of the alkaline manganese battery. These carefully designed details not only improve the overall performance and reliability of the product, but also lay a solid foundation for the market application and promotion of alkaline manganese batteries, and have important engineering significance and application prospects.

[0029] A limiting structure 14 is provided between the groove 12 of the bottom ring 1 and the vertical ring 11. The addition of this design detail plays a role in fixing the installation position when the battery is installed. Through the setting of the limiting structure 14, the sealing ring of the alkaline manganese battery can be accurately aligned and fixed in the correct position, ensuring the close fit between the sealing ring and the battery body, and improving the sealing performance and service life of the alkaline manganese battery.

[0030] It is worth mentioning that the corner where the limiting structure 14 and the vertical ring 11 are connected is designed to be arc-shaped, which makes it easier to install the sealing ring into the battery body. The setting of the arc-shaped corner allows the sealing ring to enter the battery body more smoothly during the assembly process, reduces the resistance caused by the mismatch of the corner shape, and improves the assembly efficiency and accuracy. This small design detail demonstrates the attention to user experience and the pursuit of product quality.

[0031] Through the design of the above-mentioned limiting structure 14 and the arc angle, the sealing ring structure of the alkaline manganese battery shows good operability and stability during assembly and use. The limiting structure 14 is not only used to ensure the correct position of the sealing ring, but also to avoid problems such as offset or displacement during assembly, thereby ensuring the normal operation and safe use of the battery.

[0032] In summary, the limiting structure 14 provided between the groove 12 of the bottom ring and the vertical ring 11 and the arc angle design at the connection between the limiting structure 14 and the vertical ring 11 further enhance the practicality and reliability of the sealing ring structure of the alkaline manganese battery. These carefully designed details not only ensure the close fit between the sealing ring and the battery body, but also improve the assembly efficiency and accuracy. The optimized design of the sealing ring structure of the alkaline manganese battery will bring more opportunities and potential for its market application and promotion, and has important engineering significance and application prospects.

[0033] A connecting ring 3 is provided on the side of the central column 2, and the central column 2 and the bottom ring 1 are connected through the connecting ring 3, which plays a role of stable support and connection. The design of the connecting ring 3 is exquisite and practical, providing a key guarantee for the stability and reliability of the entire alkaline manganese battery structure. Through the setting of the connecting ring 3, a tight connection is formed between the central column 2 and the bottom ring 1, ensuring the coordinated work and coordinated operation between the various components of the battery.

[0034] The edge of the connecting ring 3 away from the center column 2 is in a slide shape, which not only makes the connecting ring 3 easier to install and remove, but also has better stability and reliability when connecting the center column 2 and the bottom ring 1. The slide-shaped design allows the connecting ring 3 to slide in smoothly and be fixed in the correct position, reducing the friction and resistance generated during the installation process and improving assembly efficiency and accuracy.

[0035] Through the perfect combination of the connecting ring 3 and the arc-shaped design of the bottom edge of the center column 2, the overall structure of the alkaline manganese battery is more stable and reliable. The slide-like design of the connecting ring 3 and the arc-shaped design of the bottom edge of the center column 2 not only improve the assembly efficiency and accuracy, but also provide important guarantees for the normal operation and stability of the battery. These design details reflect the pursuit of product quality and the attention to user experience, and demonstrate the innovation and practicality of this application in the structural design of alkaline manganese batteries.

[0036] Embodiment 2:

[0037] After testing LR6 alkaline manganese batteries, 10 batteries each with chamfered corners, square corners and rounded corners passed 20 rounds of high and low temperature cycle tests, which can greatly improve the battery's leak-proof performance, and the chamfered corner type is more conducive to process production.

[0038] In modern society, batteries have become an indispensable source of energy in life. However, due to certain factors, such as long-term use, high temperature environment or improper use, batteries may leak, which will cause potential harm to the environment and human health. Therefore, it is very important to improve the leakage resistance of batteries.

[0039] The test results show that after 20 rounds of high and low temperature cycle tests, these batteries showed excellent anti-leakage performance. No matter whether they are chamfered, square or rounded corner batteries, they did not leak. This shows that the measures taken by the staff during the design and production process are indeed effective and can reduce or avoid the risk of battery leakage.

[0040] Regarding the view that chamfered batteries are more convenient in the production process, we have to mention the widespread application of chamfer design in industrial production. Chamfering is a process of cutting or trimming the edges of an object. By removing sharp edges, the risk of damage and injury to the object during use can be reduced. In battery production, chamfer design helps improve production efficiency and product quality.

[0041] First, the chamfer design can reduce the difficulty of operation during the production process. Because sharp edges increase the risk of injury to operators, the chamfered battery edges are smoother, making it easier for operators to operate during handling and assembly, reducing the possibility of errors.

[0042] Secondly, the chamfer design can also improve the overall aesthetics of the product. The chamfered battery edge is smoother, the appearance is more refined, and it gives people a sense of high quality. This is very important for improving the product image and market competitiveness.

[0043] In addition, the chamfer design can also improve the structural strength and durability of the battery. Sharp edges are easily damaged when subjected to external impact, while the chamfered battery edges are stronger and can better resist the impact of external forces, extending the battery life.

[0044] In summary, after testing LR6 alkaline manganese batteries, it was found that 10 batteries each of chamfered, square and rounded corners passed the 20 rounds of high and low temperature cycle tests, which confirmed their significant improvement in leak-proof performance. In particular, chamfered batteries, in addition to their excellent performance in leak-proof performance, also have the advantage of being more convenient in the production process. These results have positive significance for further improving battery design and improving production efficiency, and also provide users with more reliable and safer battery products.
