Description

Technical Field

[0001] This utility model relates to the field of zinc-manganese dry cell battery technology, and in particular to a zinc-manganese dry cell battery with a leak-proof structure. Background Technology

[0002] Dry cell batteries are primary batteries commonly used in daily life. The negative electrode is a zinc cylinder, and the positive electrode is a black powder column composed of a mixture of manganese dioxide powder, electrolyte, and acetylene black. A carbon rod is inserted in the middle of the positive electrode as a conductor to lead out the current. There is a layer of pulp paper between the positive and negative electrodes. A paper cup is placed at the bottom of the zinc cylinder to seal the upper part of the zinc cylinder, thus making a dry cell battery.

[0003] Currently, most zinc-manganese dry cell batteries on the market are protected only by a thin metal shell (mostly a zinc canister shell that also functions as the negative electrode) and an outer paper or plastic packaging. However, in actual use, zinc-manganese dry cell batteries are more prone to leakage due to external pressure. When the external pressure reaches a certain level, the battery shell, which is already structurally weak, is easily deformed: at best, local dents will appear, and at worst, the shell will crack, the top sealing ring will shift or fall off, easily leading to leakage. Therefore, this utility model provides a zinc-manganese dry cell battery with a leak-proof structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a zinc-manganese dry cell battery with a leak-proof structure to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A zinc-manganese dry cell battery with a leak-proof structure includes a zinc-manganese dry cell battery body, an outer shell attached to the bottom of the zinc-manganese dry cell battery body, a reinforcing tube fixedly installed on the inner wall of the outer shell, a limiting component disposed inside the reinforcing tube and connected to the zinc-manganese dry cell battery body, and a cover plate assembly disposed on the top of the outer shell.

[0006] Preferably, the limiting component includes a first limiting plate fixedly installed inside the reinforcing tube, the first limiting plate overlapping the zinc-manganese dry cell body, a second limiting plate overlapping the side of the first limiting plate, and the second limiting plate being fixedly connected to the zinc-manganese dry cell body.

[0007] Preferably, the cover plate assembly includes a cover plate overlapping the top of the outer shell, the cover plate having a slot inside, a locking block being engaged inside the slot, the locking block being fixedly connected to the outer shell, and a positive electrode through hole being provided through the top of the cover plate.

[0008] Preferably, the card slot has an L-shaped structure, and there are multiple card slots.

[0009] Preferably, a negative electrode plate is fixedly installed inside the outer casing, and the negative electrode plate is connected to the main body of the zinc-manganese dry cell battery.

[0010] Preferably, the reinforcing tube has a circular tube structure and is made of silicon nitride ceramic material.

[0011] Preferably, a sealing ring is fixedly installed at the bottom of the cover plate, and the sealing ring is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the zinc-manganese dry cell battery with a leak-proof structure, due to the high hardness of the reinforcing tube, will not easily deform when squeezed. This protects the outer side of the zinc-manganese dry cell battery body, preventing leakage caused by compression deformation. Furthermore, the setting of the limiting component facilitates the limiting of the zinc-manganese dry cell battery body, preventing it from rotating inside the casing during use, thus allowing for better use of the zinc-manganese dry cell battery.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to Figure 1-5A zinc-manganese dry cell battery with a leak-proof structure includes a zinc-manganese dry cell battery body 1, a shell 2 attached to the bottom of the body 1, a reinforcing tube 4 fixedly installed on the inner wall of the shell 2, the reinforcing tube 4 being a cylindrical tube made of silicon nitride ceramic material with a Mohs hardness of 8.5-9, resulting in high hardness and preventing easy deformation under pressure. A limiting component is installed inside the reinforcing tube 4 and connected to the zinc-manganese dry cell battery body 1. A cover plate assembly is installed on the top of the shell 2, and a negative electrode plate 3 is fixedly installed inside the shell 2. The negative electrode plate 3 is overlapped with the zinc-manganese dry cell body 1. This zinc-manganese dry cell with a leak-proof structure is protected on the outside of the zinc-manganese dry cell body 1 by the high hardness of the reinforcing tube 4 during use, which prevents it from easily deforming when squeezed. This prevents the zinc-manganese dry cell body 1 from being squeezed and deformed, thus preventing leakage. In addition, the setting of the limiting component makes it easy to limit the zinc-manganese dry cell body 1, preventing it from rotating inside the outer shell 2 during use, thus facilitating better use of the zinc-manganese dry cell.

[0017] Specifically, the limiting component includes a first limiting plate 5 fixedly installed inside the reinforcing tube 4. The first limiting plate 5 overlaps with the zinc-manganese dry cell battery body 1. A second limiting plate 6 overlaps with the side of the first limiting plate 5. The second limiting plate 6 is fixedly connected to the zinc-manganese dry cell battery body 1. During the insertion of the zinc-manganese dry cell battery body 1, the first limiting plate 5 is inserted along the gap between the second limiting plates 6. Subsequently, during the use of the zinc-manganese dry cell battery body 1, the first limiting plate 5 can limit the second limiting plate 6, thereby limiting the zinc-manganese dry cell battery body 1 and preventing the zinc-manganese dry cell battery body 1 from rotating inside the outer shell 2.

[0018] Specifically, the cover assembly includes a cover 7 overlapping the top of the outer casing 2. A sealing ring 8 is fixedly installed at the bottom of the cover 7. The sealing ring 8 is made of rubber. A slot 9 is opened inside the cover 7, and a locking block 10 is locked inside the slot 9. The slot 9 has an L-shaped structure and there are multiple slots 9. The locking block 10 is fixedly connected to the outer casing 2. A positive terminal through hole 11 is provided through the top of the cover 7. During the installation of the cover 7, the positive terminal through hole 11 on the cover 7 is aligned with the positive terminal of the zinc-manganese dry cell battery body 1, and the slot 9 is aligned with the locking block 10. As the cover 7 moves downward, it will squeeze the locking block 10, causing the locking block 10 to form a slight deformation. When the cover 7 is in close contact with the outer casing 2, the locking block 10 will return to its original shape, thereby locking in the slot 9 and limiting the cover 7. During the insertion of the cover 7, the sealing ring 8 will be locked into the outer casing 2, thereby sealing and limiting the upper and lower parts of the zinc-manganese dry cell battery body 1.

[0019] In use: Insert the zinc-manganese dry cell battery body 1 into the outer casing 2. During insertion, the first limiting plate 5 is inserted along the gap between the second limiting plates 6 until the zinc-manganese dry cell battery body 1 contacts the negative electrode plate 3. Then, install the cover plate 7, aligning the positive electrode through hole 11 on the cover plate 7 with the positive electrode post of the zinc-manganese dry cell battery body 1, and align the slot 9 with the locking block 10. As the cover plate 7 moves downward, it will squeeze the locking block 10, causing the locking block 10 to deform slightly. When the cover plate 7 is in close contact with the outer casing 2, the locking block 10 will return to its original shape and thus lock into the slot 9, limiting the cover plate 7. During the insertion of the cover plate 7, the sealing ring 8 will be locked into the outer casing 2. Subsequently, during use, because the reinforcing tube 4 has high hardness, it can protect the outside of the zinc-manganese dry cell battery body 1, preventing the zinc-manganese dry cell battery body 1 from being squeezed and deformed, thus preventing leakage.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
