Description

Technical Field

[0001] This utility model relates to the field of battery sealing rings, specifically to an explosion-proof reinforced sealing ring. Background Technology

[0002] The casing of a dry cell battery consists of, from the inside out, the battery cell, the sealing ring, and the cap. As our country develops, people's living standards continue to improve, and people's awareness of environmental protection is constantly increasing. More and more people are using green and pollution-free alkaline batteries.

[0003] Although existing dry cell batteries are equipped with explosion-proof sealing rings, they may still experience a sharp increase in internal pressure and high internal temperature when the battery is used abnormally, such as short circuit or reverse installation. This can cause the nylon material to deform excessively under internal pressure after being heated, preventing the explosion-proof groove from opening properly to release pressure and thus posing a risk of battery explosion.

[0004] Accordingly, this utility model proposes an explosion-proof reinforced sealing ring to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides an explosion-proof reinforced sealing ring. By adding three annular reinforcing ribs, it can effectively support the explosion-proof groove plane when the internal pressure of the battery rises sharply due to abnormal use and the internal temperature is generated, thereby improving the explosion-proof performance of the sealing ring and preventing the nylon material from being over-deformed under internal pressure after being heated, which could prevent the explosion-proof groove from opening normally to release pressure and cause the risk of battery explosion.

[0006] Technical solution

[0007] An explosion-proof reinforced sealing ring includes a central post and a ring sleeve disposed around the central post. The ring sleeve is further provided with a plurality of explosion-proof rings arranged in a ring around the central post and an explosion-proof groove. Each explosion-proof ring is provided with annular reinforcing ribs surrounding the central post.

[0008] Furthermore, the ring sleeve is also provided with a V-shaped annular groove surrounding the central column.

[0009] Furthermore, a central hole is provided through the central column.

[0010] Furthermore, a limiting groove is provided at one end of the central hole near the explosion-proof groove.

[0011] Furthermore, the inner wall of the ring is provided with a positioning groove.

[0012] Furthermore, one end of the annular groove is flush with one end of the central column.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] By adding three ring-shaped reinforcing ribs, the internal pressure of the battery can rise sharply due to abnormal use (short circuit, reverse installation) and high internal temperature can be effectively supported (held) to maintain the plane of the explosion-proof groove, thereby improving the explosion-proof performance of the sealing ring and preventing the nylon material from deforming excessively under internal pressure after being heated, which could prevent the explosion-proof groove from opening properly to release pressure and cause the risk of battery explosion.

[0020] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0021] have Figures 1-2 As shown, this utility model discloses an explosion-proof reinforced sealing ring, including a central column 1 and a ring sleeve 5 disposed around the central column 1. The ring sleeve 5 is also provided with a plurality of explosion-proof rings 3 arranged in a ring array around the central column 1 and an explosion-proof groove 9. Each explosion-proof ring 3 is provided with annular reinforcing ribs 7 surrounding the central column 1.

[0022] Furthermore, the ring 5 is also provided with a V-shaped annular groove 4 surrounding the central column 1.

[0023] Furthermore, a central hole 2 is provided through the central column 1.

[0024] Furthermore, a limiting groove 8 is provided at the end of the central hole 2 near the explosion-proof groove 9.

[0025] Furthermore, the inner wall of the ring 5 is provided with a positioning groove 6.

[0026] Furthermore, one end of the annular groove 4 is flush with one end of the central column 1.

[0027] Specifically, by adding three ring-shaped reinforcing ribs 7, the internal pressure of the battery can rise sharply due to abnormal use (short circuit, reverse installation) and high internal temperature can be effectively supported (held) to hold the plane of the explosion-proof groove 9, improve the explosion-proof performance of the sealing ring, and avoid excessive deformation of the nylon material under internal pressure after being heated, which could prevent the explosion-proof groove from opening normally to release pressure and cause the battery to explode.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
