Description

Technical Field

[0001] This utility model relates to the field of compressor gasket technology, and in particular to a modified compressor gasket. Background Technology

[0002] The compressor sealing gasket is a metal gasket with a raised rib in the middle and a rubber layer on the surface. During assembly, the gasket is installed between two housings. When the two housings are tightened with bolts, the two housings squeeze the raised rib of the gasket to achieve a sealing effect.

[0003] The existing product material is SUS301+FKM, and the compressor gasket adopts a full-ribbed + semi-ribbed sealing structure. This type of metal gasket has a rubber coating, but the metal gasket is applicable to the CO2 model, which requires the gasket to be conductive. However, the gasket material has a rubber coating, and the coating also plays a micro-sealing role, so the coating cannot be replaced. Therefore, the above structure cannot meet the conductivity requirements. Utility Model Content

[0004] This invention aims to solve the technical problem of existing technologies failing to meet conductivity requirements by adding protrusions and removing the coating at the protrusion locations using a laser to achieve conductivity. This results in a modified compressor gasket that meets conductivity requirements while maintaining a good seal.

[0005] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0006] A modified compressor sealing gasket includes a gasket body, the front side of the gasket body being recessed inward near the edge and having a raised rib formed on the back side of the gasket body, the gasket body being provided with a rubber coating, a first through hole being provided in the center of the front side of the gasket body, and multiple protrusions being formed on the gasket body near the first through hole, each of the protrusions extending outward from the rubber coating.

[0007] Specifically, the multiple protrusions are evenly divided into four groups, and the four groups of protrusions are distributed in a circular pattern along the center of the gasket body.

[0008] Specifically, each group of protrusions has two protrusions to meet the basic requirements of the current loop.

[0009] Specifically, the rib is an annular rib and there are two of them. The two ribs have the same center and one rib is located outside the other rib.

[0010] Specifically, the gasket body has a plurality of second through holes near its upper edge, and the plurality of second through holes are located between two protruding ribs.

[0011] Specifically, the diameter of the second through hole is greater than the distance between the two ribs, and the two ribs have an arc-shaped transition section on the outside near the second through hole, the diameter of the arc-shaped transition section being greater than the diameter of the second through hole.

[0012] Specifically, three arc-shaped grooves are provided between the multiple second through holes and the first through hole.

[0013] Specifically, a third through hole is provided between the two of the arc-shaped grooves.

[0014] Specifically, the inner wall of the first through hole has multiple arc-shaped protrusions, and a fourth through hole is provided at the connection between each arc-shaped protrusion and the gasket body. The fourth through hole is staggered from the third through hole.

[0015] This utility model has the following beneficial effects:

[0016] This application solves the technical problem of conductivity by adding protrusions. During production, protrusions are added to the gasket body 10, and the coating at the protrusion positions is removed by laser to achieve conductivity, thus meeting the conductivity requirement without affecting the seal.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0025] In one specific embodiment, please refer to the appendix. Figure 1 As shown, this utility model aims to solve the technical problem that existing technologies cannot meet conductivity requirements by providing a modified compressor sealing gasket, as shown in the attached figure. Figure 1 As shown:

[0026] A modified compressor sealing gasket includes a gasket body 10. The front side of the gasket body 10 is recessed inward near the edge, and a raised rib 11 is formed on the back side of the gasket body 10. The gasket body 10 is coated with a rubber coating. A first through hole 12 is opened in the center of the front side of the gasket body 10. A plurality of protrusions 13 are formed on the gasket body 10 near the first through hole 12, and each of the protrusions 13 extends outward from the rubber coating.

[0027] During production, the entire gasket body 10 is coated with a rubber coating, and the rubber layer at the position of the protrusion 13 is removed with a laser, so that the protrusion 13 is exposed to the outside of the rubber layer, so that the conductivity can be achieved through the protrusion 13, thus meeting the conductivity requirements, while the seal is not affected.

[0028] The multiple protrusions 13 are evenly divided into four groups, and the four groups of protrusions 13 are distributed in a circle along the center of the gasket body 10. The four groups of protrusions 13 ensure the overall conductivity of the gasket body 10.

[0029] The number of protrusions 13 in each group is two, in order to meet the basic requirements of the current circuit.

[0030] In one specific embodiment, please refer to the appendix. Figure 1 As shown, the raised rib 11 is an annular raised rib, and there are two of them. The two raised ribs 11 have the same center, and one raised rib 11 is located outside the other raised rib 11. The two raised ribs 11 are arranged concentrically to further improve the sealing effect.

[0031] The gasket body 10 has a plurality of second through holes 14 near its upper edge, and the plurality of second through holes 14 are located between two protruding ribs 11.

[0032] The diameter of the second through hole 14 is greater than the distance between the two protruding ribs 11, and the two protruding ribs 11 have an arc-shaped transition section 111 on their outer side near the second through hole 14, the diameter of the arc-shaped transition section 111 being greater than the diameter of the second through hole 14.

[0033] This application can be positioned via the second through hole 14 or used to achieve mechanical fixation by passing through fasteners, while reducing the weight of the gasket body.

[0034] In one specific embodiment, please refer to the appendix. Figure 1 As shown, three arc-shaped grooves 15 are provided between the multiple second through holes 14 and the first through holes 12 to provide deformation allowance for the gasket body 10 and reduce the risk of wear or breakage caused by rigid contact.

[0035] A third through hole 151 is provided between the two arc-shaped grooves 15 to position the gasket body 10 through the third through hole 151.

[0036] The inner wall of the first through hole 12 has multiple arc-shaped protrusions 121, and a fourth through hole 122 is provided at the connection between each arc-shaped protrusion 121 and the gasket body 10. The fourth through hole 122 is staggered from the third through hole 151.

[0037] This application can be positioned via the fourth through hole 122 or used to achieve mechanical fixation by passing through fasteners, while reducing the weight of the gasket.

[0038] In summary, this application solves the technical problem of conductivity requirements by adding bumps. During production, bumps are added to the gasket body 10, and the coating at the bump locations is removed using a laser to achieve conductivity, thus meeting the conductivity requirements while ensuring that the seal is not affected.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
