Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a sealing ring with a vacuum breaking structure. Background Art

[0002] Cylindrical batteries have excellent performance in the lithium battery family and are an indispensable member. However, steel-shell cylindrical batteries are one of the main forms of cylindrical batteries. Their battery systems have higher capacity, stable output voltage, stable electrochemical performance, and are safe and reliable.

[0003] During the manufacturing process, the baking process includes vacuuming and adding positive pressure inert gas (such as nitrogen). This requires our oven to be able to complete two-way sealing. The normal mechanism requires two sealing rings. The oven is larger during the processing process. If the previous sealing ring is used, it will cause the oven door to be sealed with the oven through the sealing ring after closing, forming a sealed cavity. After the sealed cavity is vacuumed, it will make it difficult to open the oven door quickly, which will affect the production process. Utility Model Content

[0026] Refer to Figures 1-4 As shown, it is a preferred embodiment provided by the present utility model.

[0027] A sealing ring with a vacuum-breaking structure, including a sealing main body 10 with an annular structure. The sealing main body 10 has an installation end face 20, and the installation end face 20 extends along the length direction of the sealing main body 10. A lip groove 30 with an outer opening is provided on the sealing main body 10. The lip groove 30 is arranged opposite to the installation end face 20, and a communication groove 21 communicating with the lip groove 30 is opened on the installation end face 20;

[0028] When the sealing main body 10 is squeezed by the external box door, the lip groove 30 contacts the box door to form a sealed cavity. When a vacuum structure is formed in the sealed cavity, the box door is adsorbed;

[0029] When it is necessary to open the box door, the communication groove 2 and the atmosphere are connected through the valve of the device, so that the atmosphere is connected with the sealed cavity to break the vacuum structure.

[0030] For the above-mentioned sealing ring with a vacuum-breaking structure, the sealing main body 10 can be connected with the atmosphere through the valve in the oven by using the communication groove 21, so as to break the vacuum structure and accelerate the rapid opening between the box door and the oven. This structure is simple and reasonably designed, and is suitable for wide promotion and use, solving the problem that it is difficult to quickly open the vacuum formed by the sealing connection of the sealing ring.

[0031] In this embodiment, the connecting groove 21 is connected to the lip groove 30 through the vent hole 11, and the vent hole 11 passes through the sealing body 10. In this way, the connecting groove 21 can be used to connect the outside atmosphere to the lip groove 30 through the vent hole 11, breaking the vacuum structure.

[0032] The vent holes 11 are distributed around the sealing body 10 , passing through the mounting end face 20 and the contact end face. The number of the vent holes 11 is not limited and can be adjusted according to the length of the sealing body 10 .

[0033] In this embodiment, the sealing body 10 has a first lip 40 and a second lip 50 extending outward away from the mounting end surface 20. The first lip 40 and the second lip 50 are arranged at intervals, and the first lip 40 and the sealing body 10 and the second lip 50 are connected in sequence to form a lip groove 30 with an outer opening.

[0034] During the closing process of the door, the lip groove 30 in the sealing body 10 will be compressed. There are a first lip 40 and a second lip 50 in the lip groove 30. Then, during the closing process of the door, the first lip 40 and the second lip 50 will be compressed, so that the sealing cavity can withstand both internal pressure and external pressure.

[0035] In this embodiment, the sealing body 10 has a contact end surface arranged away from the mounting end surface 20 , and the first lip 40 is provided on the upper portion of the contact end surface and is inclined outward and upward.

[0036] The second lip 50 is provided at the lower portion of the contact end surface and is inclined outward and downward.

[0037] When the door or the oven is not parallel or not flat enough, the first lip 40 and the second lip 50 have a certain inclination height and softness so that they can naturally fit onto the contact surface of the door and the oven.

[0038] In this embodiment, the connecting groove 21 is arranged along the length of the mounting end surface 20, and the sealing body 10 is provided with a plurality of vent holes 11, which are arranged at intervals along the length of the sealing body 10. In this way, the plurality of vent holes 11 can increase the speed of breaking the vacuum structure.

[0039] In this embodiment, the sealing body 10 has an inner cavity 60 formed around it, and a boss 61 is provided on the inner side wall of the inner cavity 60. In this way, the sealing body 10 can be embedded in the oven through the boss 61, thereby strengthening the connection between the sealing body 10 and the oven.

[0040] In this embodiment, the boss 61 is circumferentially arranged along the inner wall of the inner cavity 60 . The cross section of the boss 61 is arc-shaped. The boss 61 is adjacent to the first lip 40 .

[0041] In this way, the sealing performance during the sealed connection of the sealing body 10 can be improved.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
