Description

Technical Field

[0001] The utility model relates to the technical field of rubber gaskets, in particular to a novel rubber sealing gasket. Background Art

[0002] Gaskets play a vital role in battery assembly and other applications that require sealing. Traditional rubber gaskets are often used in conjunction with gaskets of other materials to achieve better sealing effects. However, due to differences in material properties, the connections between these gaskets are often not tight enough, resulting in a decrease in the overall sealing performance. In addition, when the gasket is squeezed, the sealing line on it may deform, which further reduces the sealing ability of the gasket, especially after high pressure or long-term use. These problems not only affect the normal operation of the equipment, but may also cause leakage of internal liquids, thereby affecting the safety and stability of the equipment. Therefore, the development of a new type of rubber sealing gasket that can overcome the shortcomings of the existing technology and provide a more stable and reliable connection and better sealing performance is a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a novel rubber sealing gasket, which solves the problem that the existing rubber gasket has poor safety and stability when in use.

[0004] To achieve the above object, the utility model is implemented by the following technical scheme: a new type of rubber sealing gasket, the center of the gasket has a central opening, the gasket comprises a surface sealing gasket, a rubber gasket body and an auxiliary rubber gasket arranged in sequence from top to bottom;

[0005] The auxiliary rubber gasket has a first sealing line formed on its bottom surface, and the rubber gasket body has a second sealing line formed on its bottom surface; wherein, when the gasket is squeezed, the force of the second sealing line acts on the first sealing line;

[0006] Sealing rings are arranged at the inner edge and the outer edge of the gasket.

[0007] Preferably, a cavity is formed on the inner side of the auxiliary rubber gasket, the surface sealing gasket and the rubber gasket body are both arranged in the cavity, and the top surfaces of the surface sealing gasket, the auxiliary rubber gasket and the sealing ring are all flush.

[0008] Preferably, a plurality of through holes are opened in the circumferential direction of the surface sealing gasket, and a plurality of raised columns are formed on the circumferential top of the auxiliary rubber gasket, and the raised columns are inserted into the through holes.

[0009] Preferably, the sealing ring comprises:

[0010] An outer sealing ring, wrapped around the circumferential outer edges of the surface sealing gasket and the auxiliary rubber gasket;

[0011] The inner sealing ring is arranged in the central opening and is fitted to the circumferential inner edges of the surface sealing gasket, the rubber gasket body and the auxiliary rubber gasket.

[0012] Preferably, the second sealing line includes a raised portion and a recessed portion formed on the bottom surface of the rubber gasket body; the first sealing line includes a plurality of groups of annular protrusions formed on the bottom of the auxiliary rubber gasket, and each group of the annular protrusions is arranged corresponding to the raised portion.

[0013] Preferably, the raised portion includes a sealing raised portion, and the recessed portion includes a sealing groove; wherein the sealing groove is formed between two adjacent sealing raised portions.

[0014] Preferably, each group of the annular protrusions includes at least two sealing ring lines.

[0015] Preferably, the first sealing line further includes a closed loop line, and the closed loop line is located between two adjacent groups of annular protrusions.

[0016] Preferably, the closed loop is inclined toward the central opening; an angle α is formed between the closed loop and the auxiliary rubber gasket, and 45°<α<90°.

[0017] Beneficial Effects

[0018] By using a new type of rubber sealing gasket provided by the utility model, the outer sealing ring and the inner sealing ring wrap the edge circle, and the protruding column on the auxiliary rubber gasket at the bottom is inserted into the through hole on the surface sealing gasket at the top, forming an optimized structural design connected as one, and realizing a stable connection between the rubber gasket body and the surface sealing gasket and the auxiliary rubber gasket. The structural design of this new gasket minimizes its shape change when it is squeezed, thereby maintaining good sealing performance.

[0019] At the same time, the first sealing line and the second sealing line on the gasket cooperate with each other to provide additional support when subjected to external force. When the gasket is squeezed, the sealing protrusion on the second sealing line can effectively support the annular sealing line of the first sealing line. This structural improvement significantly improves the gasket's pressure resistance and sealing stability. Even in long-term use or in extreme environments, the gasket can maintain its physical properties and sealing effect, greatly extending its service life. The use of an inclined closed loop line can deform inward according to the inclination direction when the gasket is squeezed, so that the force of the gasket is inward when it is squeezed, effectively avoiding the problem of reduced sealing effect caused by the outward deformation of the sealing line when the gasket is squeezed.

[0020] Through these improvements, the gasket not only improves the overall quality and reliability of the assembled equipment, but also helps to improve the operating efficiency and safety of the equipment, bringing significant economic and social benefits to users.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0031] Reference Figure 1-6 The novel rubber sealing gasket of this embodiment is described. The gasket in the prior art has a structure with a central opening at its center.

[0032] In this embodiment, the gasket includes a surface sealing gasket 1, a rubber gasket body 2 and an auxiliary rubber gasket 3 which are arranged in sequence from top to bottom. The surface sealing gasket 1, the rubber gasket body 2 and the auxiliary rubber gasket 3 constitute a composite gasket.

[0033] Specifically, the surface sealing gasket 1 is an annular sheet gasket with a first opening in the center; the rubber gasket body 2 is annular with a second opening in the center; the auxiliary rubber gasket 3 is annular with a third opening in the center, and its circumferential edge extends upward to form an extended edge, and a cavity 7 is formed inside the extended edge of the auxiliary rubber gasket 3. The first opening, the second opening and the third opening are on the same axis and constitute a central opening.

[0034] In this embodiment, the surface sealing gasket 1 and the rubber gasket body 2 are both disposed in the cavity 7, and the top surfaces of the surface sealing gasket 1, the auxiliary rubber gasket 3 and the sealing ring are all flush. It can be understood that the auxiliary rubber gasket 3 wraps the surface sealing gasket 1 and the rubber gasket body 2, and the rubber gasket body 2 and the auxiliary rubber gasket 3 clamp the sealing gasket 1 at the inner position.

[0035] A plurality of through holes 8 are formed in the circumference of the surface sealing gasket 1, and a plurality of protruding columns 6 are formed on the circumferential top of the auxiliary rubber gasket 3, and the protruding columns 6 are inserted into the through holes 8. The protruding columns 6 on the top of the auxiliary rubber gasket 3 are inserted into the through holes 8 of the surface sealing gasket 1 to form a connection between the auxiliary rubber gasket 3 and the surface sealing gasket 1, thereby enhancing the stability of the gasket in use and preventing the surface sealing gasket 1, the rubber gasket body 2 and the auxiliary rubber gasket 3 from being offset in position during the extrusion process, resulting in loss of gasket function.

[0036] Sealing rings are provided at the inner and outer edges of the gasket. The sealing rings include an outer sealing ring 4 and an inner sealing ring 5. The outer sealing ring 4 is wrapped around the circumferential outer edges of the surface sealing gasket 1 and the auxiliary rubber gasket 3; the inner sealing ring 5 is arranged in the central opening and fits the circumferential inner edges of the surface sealing gasket 1, the rubber gasket body 2 and the auxiliary rubber gasket 3. The outer sealing ring 4 is wrapped around the outer circle of the composite gasket, while the inner sealing ring 5 is fit to the inner circle of the composite gasket, so that the connection gap after the surface sealing gasket 1, the rubber gasket body 2 and the auxiliary rubber gasket 3 are fitted is covered, thereby increasing the connection stability.

[0037] like Figure 1 , Figure 4 and Figure 6 As shown, a first sealing line is formed on the bottom surface of the auxiliary rubber gasket 3, and a second sealing line is formed on the bottom surface of the rubber gasket body 2; wherein, when the gasket is squeezed, the force of the second sealing line acts on the first sealing line. The first sealing line is the sealing surface of the gasket, and the first sealing line is supported by the second sealing line to enhance the structural stability of the first sealing line and prevent it from deflecting or deforming when squeezed.

[0038] The second sealing line includes a raised portion and a recessed portion formed on the bottom surface of the rubber gasket body 2; the first sealing line includes a plurality of groups of annular protrusions formed on the bottom surface of the auxiliary rubber gasket 3, and each group of annular protrusions is arranged corresponding to the raised portion. The raised portion on the bottom surface of the rubber gasket body 2 supports the annular protrusion on the bottom surface of the auxiliary rubber gasket 3, so as to achieve the purpose of strengthening the structural stability of the first sealing line in the above content.

[0039] The raised portion includes a sealing protrusion 10, and the recessed portion includes a sealing groove 9, wherein a sealing groove 9 is formed between two adjacent sealing protrusions 10. Each group of annular protrusions includes at least two sealing ring lines 12.

[0040] The first sealing line also includes a closed loop line 11, which is located between two adjacent groups of annular protrusions. The closed loop line 11 is inclined in the direction of the central opening; an angle α is formed between the closed loop line 11 and the auxiliary rubber gasket, 45°<α<90°. The inclined closed loop line 11 can deform inward according to the inclined direction when the gasket is squeezed, so that the force of the gasket is inward when it is squeezed, effectively avoiding the problem of reduced sealing effect caused by the outward deformation of the sealing line when the gasket is squeezed.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
