Description

Technical Field

[0001] This utility model relates to the field of sealing plug technology, specifically a sealing plug. Background Technology

[0002] Sealing plugs are used to seal the connection between the sealed part and the fixed part to prevent leakage.

[0003] The existing sealing plugs still have the following problems: Generally, sealing plugs are often connected by threads. Although the structure is simple, the operation is a bit cumbersome when screwing them together. It takes a lot of time and effort to align and tighten them, resulting in low installation efficiency. Moreover, during the connection process, it is easy for human error or insufficient fit between parts to cause poor sealing, which increases the risk of leakage.

[0004] Therefore, a sealing plug is urgently needed to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a sealing plug to solve the problem that the spiral fit of the sealing plug is cumbersome and prone to poor sealing due to human error or insufficient fit between components.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A sealing plug, comprising:

[0008] The plug is used to fit tightly against the sealed part to prevent leakage of internal substances;

[0009] An inner sealing top head is disposed inside the plug body;

[0010] The connecting body is designed as a hollow structure and is located at the lower end of the plug body and communicates with the inner sealing head, for use in fitting, sealing and positioning with the fixing component;

[0011] The diameter of the connector extends outward from the plug body;

[0012] A sealing skirt is provided around the bottom end of the connector to fit and seal the fastener; an inner stop strip is protruding from the inner wall of the connector to limit and seal the connection position with the fastener.

[0013] As a preferred embodiment of the sealing plug, it further includes a mating component disposed on the surface of the connector near the sealing skirt, wherein the mating seal and the conformal shape of the sealed element are adapted.

[0014] As a preferred embodiment of a sealing plug, the mating assembly includes a groove and a sealing ring, the groove being recessed into the surface of the connector near the sealing skirt, and the sealing ring being placed within the groove.

[0015] As a preferred embodiment of a sealing plug, the top diameter of the plug body is smaller than the bottom diameter of the plug body, to prevent the plug body from being pulled out of the sealed component and to fit the sealed component.

[0016] As a preferred embodiment of the sealing plug, the thickness of the sealing skirt is greater than the thickness of the connector, which facilitates the connector being rolled up from the sealing skirt to detach from the fixing member, and also facilitates close contact with the fixing member.

[0017] As a preferred embodiment of the sealing plug, the sealing skirt is provided with a raised strip, which is used to match the outline of the sealed part and to roll up the connector.

[0018] As a preferred embodiment of the sealing plug, the diameter of the inner sealing top is larger than the diameter of the upper end of the connector, so that the inner sealing top can be tightly engaged with the fixing component after installation.

[0019] As a preferred option for a sealing plug, the thickness of the connector is 2-3 mm, which facilitates the connector being fitted into the fixing component for positioning.

[0020] As a preferred option for a sealing plug, both the plug body and the connector are made of elastic material, which has resilience and facilitates sealing positioning and edge rolling disassembly.

[0021] As a preferred embodiment of the sealing plug, the surface of the connector is provided with a protective layer to prevent damage to the connector.

[0022] The beneficial effects of this utility model are as follows: The hollow structure of the connector allows for a sealed and positioned fit with the fixing component, facilitating the connector's insertion into the sealed component and ensuring a tight seal with its inner wall, thus preventing leakage during use. The diameter of the connector extends outwards from the plug, making it easier to fit the connector into the fixing component and providing a wider contact area during sealing, enhancing the sealing effect. The sealing skirt surrounding the bottom of the connector tightly conforms to the surface of the fixing component, filling any gaps between the fixing component and the connector and preventing leakage. The inner stop strip protruding from the inner wall of the connector precisely seals the connection between the plug and the fixing component, ensuring consistent sealing performance and preventing the fixing component from being over-inserted into the sealing plug, thus avoiding damage to the sealing structure or the fixing component itself.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0035] In one embodiment of this utility model, such as Figure 1-3 As shown, a sealing plug is provided, comprising: a plug body 1, an inner sealing top 2, a connecting body 3, a sealing skirt 4, and an inner stop strip 5. The plug body 1 is used to tightly fit with the sealed component 8 to prevent leakage of internal substances; the inner sealing top 2 is disposed inside the plug body 1; the connecting body 3 is a hollow structure and is disposed at the lower end of the plug body 1 and communicates with the inner sealing top 2, used for fitting and sealing with the fixing component 9; the diameter of the connecting body 3 extends outward from the plug body 1; the sealing skirt 4 is disposed around the bottom end of the connecting body 3 to cooperate with and seal the fixing component 9; the inner stop strip 5 protrudes inward from the inner wall of the connecting body 3 to restrict and seal the connection position with the fixing component 9.

[0036] This utility model provides a sealing plug whose hollow structure allows for a seamless and sealed fit with the fixing member 9. This also facilitates the insertion of the connecting body 3 into the sealed member 8, ensuring a tight seal and preventing leakage during use. The diameter of the connecting body 3 extends outward from the plug body 1, making it easier to fit the connecting body 3 into the fixing member 9 and providing a wider contact area during sealing, thus enhancing the sealing effect. A sealing skirt 4 surrounding the bottom of the connecting body 3 tightly conforms to the surface of the fixing member 9, filling any gaps between the fixing member 9 and the connecting body 3 and preventing leakage. An inner stop strip 5 protruding from the inner wall of the connecting body 3 precisely seals the connection between the plug and the fixing member 9, ensuring consistent sealing performance and preventing the fixing member 9 from being over-inserted into the sealing plug, thus avoiding damage to the sealing structure or the fixing member 9 itself.

[0037] The usage process in this embodiment is as follows: insert the plug body 1 into the sealed part 8, and then insert the fixing part 9 into the connecting body 3 to complete the sealing fit.

[0038] Preferably, the top diameter of the plug body 1 is smaller than the bottom diameter of the plug body 1 to prevent the plug body 1 from being pulled out of the sealed component 8 and to fit the sealed component 8. When the top diameter of the plug body 1 is smaller than the bottom diameter, the smaller top portion is easier to insert into the opening when the plug body 1 is installed at the corresponding pipe or container opening, reducing resistance during installation, especially when manual installation is required, thus improving installation efficiency.

[0039] Preferably, the diameter of the inner sealing head 2 is larger than the diameter of the upper end of the connecting body 3, so that the inner sealing head 2 can be tightly engaged with the fixing member 9 after installation. By having the inner sealing head 2 larger than the diameter of the upper end of the connecting body 3, the inner sealing head 2 can be adapted to engage and make tight contact with the sealing part after installation, forming an effective seal.

[0040] Preferably, both the plug body 1 and the connector body 3 are made of elastic materials, such as plastic, which have resilience and facilitate sealing, positioning, and disassembly.

[0041] When inspecting and maintaining the sealed component 8, the sealing plug needs to be pulled out of the sealed component 8, then the connecting body needs to be rolled up, followed by the removal of the fixing component 9, finally yielding the complete sealing plug, sealed component 8, and fixing component 9. The pulling and rolling actions require the plug body 1 and connecting body 3 to be elastic so that they can be reinstalled. This extends the service life of the sealing plug and also facilitates practical operation.

[0042] Preferably, the thickness of the connector 3 is 2-3 mm, which facilitates the insertion of the connector 3 into the fixing member 9 for positioning. The thickness range in this embodiment ensures the sealing of the connection and also ensures that the connector 3 can be easily rolled up, improving the convenience of subsequent disassembly.

[0043] The surface of connector 3 is provided with a protective layer, which can be a rubber coating, applied by coating method to the surface of connector 3. The protective layer is used to prevent damage to connector 3 and extend its service life. When the rubber coating fills the micropores, it forms a continuous and relatively dense protective barrier on the surface of connector 3, further enhancing the overall sealing and protective performance of connector 3.

[0044] Preferably, the thickness of the sealing skirt 4 is greater than the thickness of the connector 3. During installation, the thicker sealing skirt 4 can better compensate for any unevenness or gaps that may exist between the sealed components 8, and the thicker sealing skirt 4 can protect the connector 3 and other internal structures. If the installation surface has rough or sharp parts, the thicker sealing skirt 4 can protect the connector 3 and internal structures, ensuring that the integrity and function of the sealing plug are not affected.

[0045] Furthermore, when the sealing plug needs to be removed, the thicker sealing skirt 4 is easier to grasp or roll up with tools or by hand. This makes the removal process easier and reduces damage to other parts of the sealing plug and the object being sealed.

[0046] Preferably, the sealing skirt 4 is provided with a raised strip 6. The raised strip 6 can fit tightly against the outline of the sealed part 8, minimizing any possible gaps between them, thereby enhancing the sealing effect and effectively preventing internal substances from leaking from the seal. When it is necessary to disassemble the sealing plug, the raised strip 6 can serve as a convenient point of force application. The operator can use tools or manually grasp the raised strip 6 to roll up the connecting body 3, thus more easily separating the sealing plug from the sealed part 8. Compared to directly operating on the smooth sealing skirt 4 or connecting body 3, the raised strip 6 makes the disassembly process easier, reduces the difficulty of disassembly, saves disassembly time, and also reduces damage to the sealing skirt 4, connecting body 3, and the sealed part 8 itself during disassembly.

[0047] like Figure 4-6As shown, this type of sealing plug also includes a mating component 7, disposed on the surface of the connector 3 near the sealing skirt 4, for mating sealing and adaptively conforming to the outer contour of the sealed component 8. Specifically, the mating component 7 includes a groove a and a sealing ring b. The groove a is recessed into the surface of the connector 3 near the sealing skirt 4, and the sealing ring b is placed in the groove a. When the sealing ring b and the groove a are separate, the separate sealing ring b can be more easily adapted to pipes with different inner diameters. This is because it can match various pipe inner diameters by adjusting its position within the groove a or by using sealing rings of different specifications, thus improving the adaptability of this type of sealing plug.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
