Description

Technical Field

[0001] This utility model relates to the field of gaskets, and in particular to a high flatness gasket. Background Technology

[0002] A washer is a part placed between a connected component and a nut. It is generally a flat metal ring used to protect the surface of the connected component from scratches by the nut and to distribute the pressure of the nut on the connected component. Existing flat washers are generally produced by stamping, where the raw material is broken between the upper and lower dies. This results in a flange forming on one side at the edge of the product due to the ductility of the metal, leading to uneven flatness. In actual use, if the flanged surface of the washer accidentally comes into contact with the mounting surface, it may scratch the product; if the flanged surface faces upwards, it may also scratch the operator.

[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high flatness gasket. This utility model is achieved through the following technical solution:

[0005] A high flatness gasket includes a lower piece and an upper piece. The upper piece has a flange groove in the middle, and the lower piece is disposed in the flange groove. A receiving groove is provided on the bottom surface of the flange groove. The outer diameter of the receiving groove is not less than the diameter of the lower piece, and the thickness of the lower piece is greater than the height of the flange groove.

[0006] In the above technical solution: the lower piece is used to contact the bolt; the upper piece is used to contact the mounting surface; the flange groove is used to accommodate the lower piece; the receiving groove is used to accommodate the flange of the lower piece; the thickness of the lower piece is greater than the height of the flange groove, making it less likely for the flange of the upper piece to scratch the operator.

[0007] A further feature of this invention is that the inner diameter of the flange groove is the same as the outer diameter of the receiving groove.

[0008] In the above technical solution, the inner diameter of the flange groove is consistent with the outer diameter of the receiving groove, so that the flange of the upper piece can be more easily placed into the receiving groove.

[0009] A further feature of this invention is that the inner diameter of the flange groove is the same as the outer diameter of the lower piece.

[0010] In the above technical solution, the inner diameter of the flange groove is the same as the outer diameter of the lower piece, so that the lower piece will not move arbitrarily after it is installed.

[0011] A further feature of this invention is that the inner diameter of the lower piece is the same as the inner diameter of the upper piece.

[0012] In the above technical solution: the inner diameter of the lower piece is the same as the inner diameter of the upper piece, which makes it easy to align the holes of the lower and upper pieces, and the bolt will not be obstructed when it is inserted.

[0013] A further feature of this invention is that the lower piece and the upper piece can rotate relative to each other.

[0014] In the above technical solution: In this embodiment, the lower piece and the upper piece can rotate relative to each other, so that the upper piece will not rotate when the bolt is rotated, thereby reducing the friction between the upper piece and the mounting surface and thus avoiding scratches on the mounting surface.

[0015] A further feature of this invention is that a slot is provided in the flange groove, and a block is provided on the lower piece, wherein the slot engages with the block.

[0016] In the above technical solution: In this embodiment, a slot is provided in the flange groove, and a block is provided on the lower piece. The slot and the block engage, so that the lower piece and the upper piece can rotate synchronously, which facilitates the replacement of the lower piece or the upper piece.

[0017] A further feature of this invention is that the lower piece and the upper piece are fixedly connected.

[0018] In the above technical solution, the lower piece and the upper piece are fixedly connected, so that the two are solidified into one, resulting in better overall integrity.

[0019] This utility model discloses a high-flatness gasket, which, compared with the prior art:

[0020] 1. By setting up a lower piece, an upper piece, and a receiving groove, this utility model ensures that the flange of the upper piece of the gasket will not contact the mounting surface, while the flange of the lower piece is hidden in the receiving groove, thus preventing scratches to operators and improving the flatness of the top and bottom surfaces of the overall gasket formed by the upper and lower pieces.

[0021] 2. This utility model can form several embodiments through the connection between the upper and lower pieces to meet different needs in actual use. Attached Figure Description
