Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal gasket technology, and in particular to a metal gasket. Background Technology
[0002] Metal washers are typically made of high-precision, high-hardness high-carbon steel, stainless steel, or brass, and are widely used in electronic instruments, mold manufacturing, precision machinery, hardware parts, mechanical parts, and stampings. However, metal washers are often not used with shafts, and they usually require a spring to achieve their elastic function, making them inconvenient to use. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal gasket.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A metal gasket is designed, comprising a first sheet and a second sheet. The lower ends of the first sheet and the second sheet are connected by two elastic arc-shaped connecting pieces. A first through hole is formed on the surface of the first sheet, and a second through hole is formed on the surface of the second sheet. An extension is provided at the rear end of the second through hole. Two straightening through holes are formed on the surface of the second sheet, and the two straightening through holes are respectively arranged on both sides of the second through hole. Reinforcing components are provided on both sides of the first sheet.
[0006] Preferably, the reinforcement component includes two connecting parts, which are integrally formed on both sides of the first piece. Each of the two connecting parts has an additional block on its opposite side surface. Each additional block has a first raised part at both its upper and lower ends, and the first raised part is arranged inclined forward from bottom to top.
[0007] Preferably, the upper end of the second piece is provided with a second raised portion, which is arranged from bottom to top and rearward.
[0008] Preferably, a first reinforcing block is provided in a ring at the connection between the extension and the second piece.
[0009] Preferably, the elastic arc-shaped connecting piece has a second reinforcing block on both sides of its surface.
[0010] Preferably, the cross-section of the second reinforcing block is trapezoidal, and the front and rear surfaces of the second reinforcing block are arc-shaped.
[0011] The metal gasket proposed in this utility model has the following advantages: the extension is fitted onto the rotating shaft, the second piece is then attached to the component to be installed, and finally, the nut is screwed onto the component to secure it. Because the elastic arc-shaped connecting piece connects the two first and second pieces, the metal gasket is elastic. Through the provided straightening through hole, the first and second pieces can be made to tend to be parallel when the nut is screwed on. In summary, the metal gasket is tightly connected to the rotating shaft through the extension, and the metal gasket can achieve its elastic function without the need for a spring, making it very convenient to use.

[0013] Figure 2 This is a schematic diagram of the rear structure of this utility model.
[0014] In the figure: First piece 1, Second piece 2, Elastic arc-shaped connecting piece 3, First through hole 4, Second through hole 5, Extension 6, Correction through hole 7, Connecting part 8, Additional block 9, First raised part 10, Second raised part 11, First reinforcing block 12, Second reinforcing block 13. Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figure 1-2 A metal gasket includes a first sheet 1 and a second sheet 2. The lower ends of the first sheet 1 and the second sheet 2 are connected by two elastic arc-shaped connecting pieces 3. A first through hole 4 is opened on the surface of the first sheet 1, and a second through hole 5 is opened on the surface of the second sheet 2. An extension 6 is provided at the rear end of the second through hole 5. Two straightening through holes 7 are opened on the surface of the second sheet 2. The two straightening through holes 7 are respectively arranged on both sides of the second through hole 5. Reinforcing components are provided on both sides of the first sheet 1.
[0017] The reinforcing component includes two connecting parts 8, which are integrally formed on both sides of the first piece 1. Each of the opposing surfaces of the two connecting parts 8 has an additional block 9. Each additional block 9 has a first raised portion 10 at both its upper and lower ends, with the first raised portion 10 arranged inclined upwards and forwards. By setting up the reinforcing component, the contact area between the first piece 1 and the nut can be increased. The first raised portion 10 provides elasticity to the first piece 1 and also increases its strength.
[0018] The upper end of the second piece 2 is provided with a second raised portion 11, which is arranged at an upward and backward angle. The second raised portion 11 serves to increase the strength of the second piece 2.
[0019] A first reinforcing block 12 is provided in a ring at the connection between the extension 6 and the second piece 2. This strengthens the connection between the extension 6 and the second piece 2.
[0020] The elastic arc-shaped connecting piece 3 has a second reinforcing block 13 on both sides to strengthen the elastic arc-shaped connecting piece 3.
[0021] The cross-section of the second reinforcing block 13 is trapezoidal, and the front and rear surfaces of the second reinforcing block 13 are arc-shaped to prevent breakage at the point where the second reinforcing block 13 connects with the elastic arc-shaped connecting piece 3.
[0022] Working principle: The extension part 6 is fitted onto the rotating shaft, and then the second piece 2 is attached to the component to be installed. The nut is then screwed onto the component to tighten it. Because the elastic arc-shaped connecting piece 3 connects the two first pieces 1 and the second piece 2, the metal washer is elastic. Through the corrective through hole 7, the first pieces 1 and the second pieces 2 can be made to be parallel when the nut is screwed on. In summary, the metal washer is tightly connected to the rotating shaft through the extension part 6, and the metal washer can achieve its elastic function without the need for a spring, making it very convenient to use.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
