Description

Technical Field

[0001] The utility model belongs to the technical field of gaskets, in particular to a metal cylinder gasket. Background Art

[0002] Cylinder gasket is a sealing gasket used in engines, located between the cylinder head and cylinder block of the engine. Its main function is to achieve the seal between the cylinder head and the cylinder block, prevent water and oil leakage, and maintain the sealing performance of the compression chamber. Cylinder gaskets are usually made of high temperature resistant, pressure resistant and corrosion resistant materials, such as metal interlayer, composite material or rubber. Cylinder gasket plays a very important role in the engine. It not only affects the working efficiency and performance of the engine, but also is directly related to the safety and reliability of the engine.

[0003] Screen printing is a common printing process, which involves applying ink or paint on a screen and then printing the pattern on materials such as cylinder gaskets. Screen-printed metal cylinder gaskets refer to printing specific patterns or text on metal cylinder gaskets through the screen printing process, which can be used for identification, decoration or other functions. The metal cylinder gaskets used in the prior art are mainly divided into two types: all-metal cylinder gaskets and multi-layer cylinder gaskets. The surface layer of all-metal gaskets is easy to fall off after being used for a period of time, resulting in a lack of sealing. General multi-layer cylinder gaskets have an upper and lower layer structure, and the metal gaskets of each layer are connected by welding, which results in uneven force and poor sealing.

[0004] A composite cylinder head gasket is disclosed in the patent with publication number CN113550838A. The cylinder gasket of this structure is arranged in a three-layer structure and is provided with a welding groove separately. However, the welding process directly affects the welding effect. Once the welding is inaccurate, convex points will be formed and the gasket will be subjected to uneven force when in use, which will eventually affect its sealing performance. Utility Model Content

The setting of these holes achieves the effect of effective sealing, heat dissipation and protection of the engine through the structural design and function of the metal cylinder gasket.

[0036] like Figure 2 As shown, the gasket body 1 includes a panel 13, a core plate 12 and a bottom plate 11; a connecting groove 15 is provided on the top of the core plate 12, and a connecting block 17 is fixedly connected to the bottom of the panel 13; a connecting head 20 is fixedly connected to the bottom of the core plate 12, and a connecting hole 10 is provided on the bottom plate 11.

[0037] like Figures 3 to 6As shown, a pressure head 14 is fixedly connected to the middle of the connection groove 15, a pressure groove 16 is provided at the middle of the bottom of the connection block 17, the connection block 17 is connected to the connection groove 15, and the pressure groove 16 cooperates with the pressure head 14; a first annular deforming member 22 is provided on the outer side of the bottom of the connection head 20, and a first receiving groove 23 is provided on the outer side of the bottom of the connection hole 10; the connection head 20 is connected to the connection hole 10, and the first deforming member 22 is cooperated and connected to the first receiving groove 23. The first deforming member 22 can be deformed after being pressurized. The pressure head 14 is used to be inserted into the pressure groove 16 and make the bottom of the connection block 17 open outward. The panel 13 is connected to the core plate 12 through the connection of the connection block 17 and the connection groove 15, and the core plate 12 is connected to the bottom plate 11 through the connection of the connection head 20 and the connection hole 10. Specifically, during production, the panel 13, the core plate 12 and the bottom plate 11 can be produced separately, and then assembled and used when in use. During assembly, first align the core plate 12 with the bottom plate 11, and insert the connector 20 at the bottom of the core plate 12 into the connecting hole 10; align the panel 13 with the core plate 12, and insert the connecting block 17 of the panel 13 into the connecting groove 15. Place the assembled gasket body 1 between the cylinder block and the cylinder head; the gasket body 1 will be pressurized when the cylinder block and the cylinder head are connected. The pressure head 14 in the connecting groove 15 will be pressed against the pressure groove 16, and the pressure head 14 will cause the bottom of the connecting block 17 to slightly expand outward, and the expanded connecting block 17 will be stuck in the connecting groove 15, and will become tighter and tighter. Figure 8 As shown, the first deformable member 22 will deform after being compressed, and the deformed first deformable member 22 will fill the first receiving groove 23 and connect the core plate 12 and the bottom plate 11 together to form a riveted connection structure. Therefore, through this design of the utility model, the panel 13, the core plate 12 and the bottom plate 11 do not need to be connected by welding, no convex points will be generated, and the whole is evenly stressed during use, thereby effectively ensuring the sealing performance.

[0038] In a preferred embodiment, Figure 6 As shown, a protective member 2 is provided in the cylinder hole 3; an extension portion 18 is provided on the top of the protective member 2, the extension portion 18 is located on the top of the panel 13 and connected to the panel 13, and the bottom of the protective member 2 is connected to the bottom plate 11. When in use, the position of the cylinder hole 3 is subjected to greater force and has higher requirements for sealing, so a separate protective member 2 is designed to improve the strength and sealing of the position of the cylinder hole 3. An extension portion 18 is provided on the top of the protective member 2, and the extension portion 18 is connected to the top of the panel 13 to form a stable and high-strength structure.

After the protective member 2 is compressed, the second deformation member 25 is deformed and filled in the second receiving groove 24, and the protective member 2 is connected to the bottom plate 11 through the second deformation member 25, thereby ensuring the stability of the protective member 2 and thus ensuring the sealing effect. At the same time, this design also has the advantage of being tighter with pressure, so that the protective member 2 can be stably connected with the gasket body 1. Through the design that a circle of second deformation members 25 is provided on the outer side of the bottom of the protective member 2 and a circle of second receiving grooves 24 are provided on the outer side of the bottom of the cylinder hole 3 in the preferred embodiment, the stable connection and sealing function of the protective member 2 are realized. When the protective member 2 is compressed, the second deformation member 25 is deformed and filled in the second receiving groove 24, thereby firmly connecting the protective member 2 to the bottom plate 11, thereby ensuring the stability and sealing effect of the protective member 2. Another advantage of this design is that the second deformable member 25 has the characteristic of being tighter as it is pressed, making the connection between the protective member 2 and the gasket body 1 more secure and reliable. Further optimized, a circle of second deformable grooves 26 are provided at the bottom of the protective member 2 near the second deformable member 25. The second deformable grooves 26 are conducive to the deformation of the second deformable member 25 after being pressed, and can guide the second deformable member 25 to deform in the direction of the second accommodating groove 24.

[0041] In a preferred embodiment, if Figure 7 as well as Figure 8 As shown, a circle of first deformation grooves 21 are arranged at the bottom of the connector 20 near the first deformation member 22. The first deformation grooves 21 are also used to facilitate the deformation of the first deformation member 22, and can also guide the first deformation member 22 to deform toward the first accommodation groove 23.

[0042] In a preferred embodiment, if Figure 2As shown, a wrapping edge 9 is arranged on the outer side of the core plate 12, and the wrapping edge 9 encloses a wrapping space, and the panel 13 is arranged in the wrapping space. This design can facilitate the installation of the panel 13, and the wrapping space is adapted to the size of the panel 13, so that the panel 13 can be limited, and the connection stability between the panel 13 and the core plate 12 is ensured, thereby ensuring the sealing effect of the gasket body 1.

[0043] In a preferred embodiment, a material film is provided on the upper surface of the panel 13, and the material film is made of nano-scale silicon oxide, aluminum oxide or titanium dioxide. In this preferred embodiment, a material film is provided on the upper surface of the panel 13, and the material film is made of nano-scale silicon oxide, aluminum oxide or titanium dioxide to provide excellent protection performance and durability.

[0044] In a preferred embodiment, Figure 2 As shown, the edges and corners of the panel 13 are set to be rounded chamfers, the edges and corners of the core plate 12 are set to be rounded chamfers, and the edges and corners of the bottom plate 11 are set to be rounded chamfers. Through this design, the sharpness of the edges and corners of the panel 13, the core plate 12 and the bottom plate 11 can be reduced, thereby improving the safety of the overall structure and effectively preventing the metal cylinder gasket from scratching the hands of the staff when installing the metal cylinder gasket.

[0045] In a preferred embodiment, Figure 4 As shown, the cross-section of the pressure head 14 is triangular, and the cross-section of the pressure groove 16 is triangular; the width of the bottom of the pressure groove 16 is smaller than the width of the bottom of the pressure head 14. This design is to ensure that the pressure head 14 can stably separate the connection block 17. After the panel 13 is connected to the core board 12, the inner wall of the pressure groove 16 contacts the outer wall of the pressure head 14, and at the same time, there will be a certain gap between the pressure head 14 and the bottom of the connection groove 15. After being pressurized, the triangular pressure head 14 gives a certain lateral component of force to the connection block 17, so that the bottom of the connection block 17 can be separated, so that the connection block 17 can be stably stuck in the connection groove 15, ensuring the connection stability between the panel 13 and the core board 12.

[0046] When the utility model is in use, first align the core plate 12 with the bottom plate 11, and insert the connecting head 20 at the bottom of the core plate 12 into the connecting hole 10; align the panel 13 with the core plate 12, and insert the connecting block 17 of the panel 13 into the connecting groove 15. Insert the protective part 2 into the cylinder hole 3, and place the assembled gasket body 1 between the cylinder body and the cylinder head; the gasket body 1 will be pressurized when the cylinder body and the cylinder head are connected. After being pressurized, the pressure head 14 in the connecting groove 15 will press against the pressure groove 16, and the pressure head 14 will cause the bottom of the connecting block 17 to slightly open outward, and the outward-opened connecting block 17 will be stuck in the connecting groove 15, and the pressure will become tighter and tighter. Figure 8As shown, the first deformable member 22 will deform after being compressed, and the deformed first deformable member 22 will fill the first receiving groove 23 and connect the core plate 12 and the bottom plate 11 together to form a riveted connection structure.
