Description

Technical Field

[0001] This utility model relates to the technical field of gaskets, specifically a stainless steel alternative to copper gasket structure. Background Technology

[0002] In simple terms, a gasket is a sealing element that is widely used in mechanical, equipment, and piping systems to prevent leakage at joints. Commonly used gaskets are mostly made of rubber, metal, etc. As disclosed in publication number CN208686954U, a sealing gasket includes an annular body and a through hole. The through hole is located in the middle of the annular body. The annular body includes an upper gasket portion, a main body, and a lower gasket portion. The upper gasket portion is located above the main body, and the lower gasket portion is located below the main body. The upper gasket portion has a first arc-shaped groove, and two first arc-shaped grooves are located on both sides of the upper gasket portion. The lower gasket portion has a second arc-shaped groove, and two second arc-shaped grooves are located on both sides of the lower gasket portion. The annular body includes an upper annular surface and a lower annular surface. The two ends of the first arc-shaped groove are connected to the upper annular surface and the main body, respectively, and the two ends of the second arc-shaped groove are connected to the lower annular surface and the main body, respectively. This sealing gasket can achieve better sealing and effectively improve the sealing performance of the gasket; in addition, it is easy to process, has low cost, and is convenient to install. However, in the existing technology, most commonly used metal gaskets are made of stainless steel. Stainless steel gaskets have good performance but are expensive to manufacture and purchase. They are also inconvenient to combine, or they are prone to slippage during combination, which affects the sealing effect. In addition, there is no anti-slip mechanism between the outer side of the gasket and the external object, which makes the gasket prone to loosening. For example, the comparative patents listed above have this problem. To address these issues, we propose a stainless steel alternative to copper gasket structure. Utility Model Content

[0003] The purpose of this utility model is to provide a stainless steel alternative to copper sealing gasket structure, in order to solve the problem that most of the commonly used metal sealing gaskets mentioned in the background art are made of stainless steel. Stainless steel sealing gaskets have good performance, but their manufacturing and procurement costs are high. Moreover, it is inconvenient to combine sealing gaskets, or slippage may occur during combination, affecting the sealing effect. Furthermore, there is a lack of anti-slip mechanism between the outer side of the sealing gasket and external objects, which makes the sealing gasket prone to loosening.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel alternative copper sealing gasket structure, comprising a sealing gasket body and an intermediate groove formed in the middle of the sealing gasket body; Also includes: The sealing gasket body and the intermediate gasket are designed separately, and the intermediate gasket is engaged in the intermediate groove. At the same time, the intermediate gasket and the intermediate groove are interference fit. A fixing protrusion for positioning is fixedly connected to the lower edge of the sealing gasket body, and fixing teeth for anti-slip are provided at equal angles on the edge of the sealing gasket body.

[0005] As a preferred embodiment of this utility model, both the sealing gasket body and the intermediate gasket are made of copper.

[0006] By adopting the above technical solution, both the sealing gasket body and the intermediate gasket are made of copper, which replaces the traditional stainless steel material, greatly reducing production and procurement costs.

[0007] As a preferred technical solution of this utility model, fixing holes are provided at equal angles on the upper edge of the sealing gasket body.

[0008] The above technical solution uses fixing holes at equal angles on the upper edge of the sealing gasket body to facilitate the positioning of the sealing gaskets at both the upper and lower ends.

[0009] As a preferred embodiment of this utility model, the fixing holes and fixing protrusions are arranged in a one-to-one correspondence, and the fixing protrusions are engaged and connected in the fixing holes of another sealing gasket body below.

[0010] By adopting the above technical solution, the fixing holes and fixing protrusions are arranged in a one-to-one correspondence, and the fixing protrusions are engaged and connected in the fixing holes of the other sealing gasket body below, which can limit the movement between the sealing gasket bodies at the upper and lower ends during combined use.

[0011] As a preferred technical solution of this utility model, a limiting groove is provided at the edge of the intermediate groove, and a positioning piece is engaged in the limiting groove and is set at an equal angle on the outside of the intermediate pad.

[0012] By adopting the above technical solution, a limiting groove is set at the edge of the intermediate groove, and a positioning piece set at an equal angle on the outside of the intermediate gasket is engaged in the limiting groove. This facilitates the engagement and limiting between the intermediate gasket and the sealing gasket body. The intermediate gasket can be used or not, depending on the actual use scenario, and the sealing gasket body can be used as a sealing ring or sealing gasket, thus enriching the use scenarios.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This stainless steel alternative copper sealing gasket structure, with both the sealing gasket body and the intermediate gasket made of copper, has lower production and procurement costs compared to traditional stainless steel materials. When the sealing gasket body is used in combination, the sealing gasket body can drive the fixing protrusion to be inserted into the fixing hole of the lower sealing gasket body, which can position the individual sealing gasket bodies at both ends and prevent loosening during combination. Combined with the split design between the intermediate gasket and the sealing gasket body, it can be used as a sealing gasket when the sealing gasket body and the intermediate gasket are used together, and it can also be used as a sealing gasket when the sealing gasket body is used alone, which enriches the actual application scenarios. Moreover, combined with the fixing teeth adhering to the external object, it can play a good anti-slip role and improve the stability between the sealing gasket body and the external object. 1. It is equipped with a sealing gasket body and an intermediate gasket. When the sealing gasket body is used alone, it can be used as a sealing ring. When the sealing gasket body and the intermediate gasket are used together, it can be used as a sealing gasket, which makes it easy to change according to the actual use scenario and has a wide range of use scenarios. 2. It is equipped with fixing holes, fixing protrusions and fixing teeth. The fixing protrusions are engaged with the fixing protrusions of the lower sealing gasket body, so that during the combined use, it is easy to limit the positioning between the upper and lower sealing gasket body units and prevent loosening. Combined with the fixing teeth, it can be attached to the external object to improve the stability of the sealing gasket body during use. Attached Figure Description

[0017] Please see Figures 1-5 .

[0018] To address the issue that most commonly used metal gaskets in existing technologies are made of stainless steel, which offers good performance but is expensive to manufacture and purchase, inconvenient to combine, and prone to slippage during combination, affecting the sealing effect, and lacks anti-slip mechanisms between the outer side of the gasket and external objects, leading to loosening, this solution proposes a stainless steel alternative copper gasket structure. This structure comprises a gasket body 1 and a central groove 2 located in the middle of the gasket body 1. A separate gasket 6 is designed to be fitted into the gasket body 1 and engages with the central groove 2. A fixing protrusion 5 for positioning is fixedly connected to the lower edge of the gasket body 1, and fixing teeth 8 for anti-slip are provided at equal angles along the edge of the gasket body 1. like Figure 1 and Figure 5 As shown, when used alone, the sealing gasket body 1 can function as a sealing ring. When combined with the intermediate gasket 6, it functions as a sealing gasket. The configuration can be adjusted according to the specific application. When the sealing gasket body 1 and the intermediate gasket 6 are combined, the intermediate gasket 6 is directly engaged at the upper and lower ends of the intermediate groove 2, with an interference fit between the intermediate gasket 6 and the intermediate groove 2. Furthermore, a positioning piece 7 is provided on the side of the intermediate gasket 6. The intermediate gasket 6 drives the positioning piece 7 to engage in the limiting groove 3, further limiting the movement between the intermediate gasket 6 and the sealing gasket body 1. When multiple sealing gasket bodies 1 need to be combined, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing protrusion 5 is fixedly connected to the lower end of the sealing gasket body 1, and a fixing hole 4 is opened at the upper end of the sealing gasket body 1. The fixing protrusion 5 and the fixing hole 4 are arranged in a one-to-one correspondence. The sealing gasket body 1 drives the fixing protrusion 5 to engage in the fixing hole 4 of the lower sealing gasket body 1, thereby facilitating the positioning between the individual units of the upper and lower sealing gasket bodies 1 and preventing loosening during the combined use. In addition, fixing teeth 8 are provided at equal angles on the outer side of the sealing gasket body 1. The fixing teeth 8 adhere to the external object during use. The fixing teeth 8 can play a good anti-slip role for the sealing gasket body 1 and improve the stability of the sealing gasket body 1 during use. Moreover, both the sealing gasket body 1 and the intermediate gasket 6 are made of copper, which has lower production and procurement costs compared to sealing gaskets made of traditional stainless steel.
