Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gasket, specifically to a high sealing gasket of preventing fracture. BACKGROUND

[0002] In many fields such as mechanical manufacturing, electronic equipment, automobile industry, aerospace, the connection mode of screw and nut has become one of the most commonly used fastening means due to its advantages of simple operation and reliable connection. As a key part between screw or nut and connecting component, gasket plays an indispensable role in the whole connection system.

[0003] In practical application, gasket fracture is a frequent problem to be solved. In some high-vibration and high-impact working environments, such as strong vibration generated during operation of automobile engine and complex mechanical impact borne by aero-engine during flight, gasket will be subjected to continuous alternating stress. Due to insufficient material toughness and unreasonable structure design, ordinary gasket is prone to crack and gradually expand under long-term stress cycle, and finally leads to fracture. Once the gasket is fractured, the connection between screw and nut will lose the necessary fastening force, and the connecting component may be loose or even separated, which seriously affects the normal operation of the equipment and even causes safety accidents. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a high sealing gasket of preventing fracture, which solves the problem that ordinary gasket is prone to crack and gradually expand under long-term stress cycle due to insufficient material toughness and unreasonable structure design.

[0005] To achieve the above purpose, the utility model discloses the following technical scheme: a high sealing gasket of preventing fracture, comprising upper gasket and lower gasket, the upper gasket and the lower gasket are annular, the outer surface inner end of the upper gasket and the lower gasket is equipped with annular rubber pad, the outer surface of the upper gasket and the lower gasket is provided with reinforcing rib one, the reinforcing rib one is at the outer side of rubber pad, the reinforcing rib one is annular equidistantly arranged around the axis of the upper gasket and the lower gasket, the reinforcing rib one is connected through reinforcing ring one, the reinforcing ring one is fixed on the outer surface of the upper gasket and the lower gasket.

[0006] Preferably, the upper gasket and the lower gasket are annularly fixed with reinforcing ring two on the upper and lower ends of the circumferential side, the reinforcing ring two is connected through reinforcing rib two, and the reinforcing rib two is equidistantly fixed on the circumferential side of the upper gasket and the lower gasket.

[0007] Preferably, the inner end of the inner surface of the upper gasket is provided with a mounting groove, a sealing ring is bonded to the inner end of the mounting groove, and a mounting ring is provided on the outer side of the mounting groove.

[0008] Preferably, the inner end of the inner surface of the lower washer is provided with a second mounting ring, the outer side of the second mounting ring is provided with a second mounting groove, and the inner end of the second mounting groove is bonded with a second sealing ring.

[0010] Preferably, the upper washer and the lower washer are provided with wedge-shaped toothed surfaces on their corresponding surfaces.

[0011] This invention provides a high-sealing gasket that is resistant to breakage. It has the following beneficial effects:

[0012] (1) In this utility model, the reinforcing rib is fixed on the washer and the reinforcing ribs are connected by a reinforcing ring, forming a more stable structural system. When subjected to complex mechanical impacts, the reinforcing ring and the reinforcing rib work together to resist external forces and prevent the washer from breaking due to excessive local deformation.

[0013] (2) The present invention achieves a sealed connection between the upper gasket and the lower gasket by matching the mounting groove one and the mounting ring two, and the mounting ring one and the mounting groove two are matched accordingly. At the same time, the annular rubber gasket can achieve a seal between the gasket and the connecting parts, thereby preventing moisture from entering the connection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1: Please refer to Figures 1-4 A high-sealing gasket with anti-breakage properties includes an upper gasket 1 and a lower gasket 2, both of which are annular. An annular rubber pad 5 is installed on the inner end of the outer surface of both the upper gasket 1 and the lower gasket 2. A reinforcing rib 3 is provided on the outer surface of both the upper gasket 1 and the lower gasket 2. The reinforcing rib 3 is located outside the rubber pad 5 and is arranged equidistantly in an annular shape around the axis of the upper gasket 1 and the lower gasket 2. The reinforcing ribs 3 are connected by a reinforcing ring 4, which is fixed to the outer surface of the upper gasket 1 and the lower gasket 2.

[0022] Both the upper washer 1 and the lower washer 2 are fixedly provided with reinforcing rings 8 in a ring shape at the upper and lower ends of their periphery. The reinforcing rings 8 are connected by reinforcing ribs 7, which are fixedly provided at equal intervals on the periphery of the upper washer 1 and the lower washer 2.

[0023] Specifically, reinforcing ribs 3 are arranged equidistantly in a ring around the axes of the upper washer 1 and the lower washer 2. The reinforcing ribs 3 are connected by reinforcing rings 4, which are fixed to the outer surfaces of the upper washer 1 and the lower washer 2. The reinforcing rings 4 connect the reinforcing ribs 3 into a unified whole, enhancing their synergistic effect. When the washer is subjected to external stress, the unified structure formed by the reinforcing ribs 3 and the reinforcing rings 4 improves the overall structural strength and stability of the washer. Under complex stress, the reinforcing rings 4 and the reinforcing ribs 3 work together to better resist external forces, preventing crack propagation caused by local deformation of the washer.

[0024] Both the upper washer 1 and the lower washer 2 have reinforcing rings 8 fixedly arranged in a ring shape at their upper and lower ends. The reinforcing rings 8 are connected by reinforcing ribs 7, which are equidistantly fixed on the periphery of the upper washer 1 and the lower washer 2. This enhances the strength and rigidity of the washer periphery, allowing the washer to better resist deformation and fracture when subjected to circumferential stress (such as torsional force). The reinforcing rings 8 provide stable support points for the reinforcing ribs 7, which in turn further disperse the circumferential stress, improving the crack resistance of the washer periphery.

[0025] The use of reinforcing ribs and rings significantly improves the fracture resistance of washers, enabling them to maintain good structural integrity under long-term stress cycles. This reduces failures caused by fractures, greatly extends the service life of washers, reduces the frequency of washer replacement, and improves the reliability and stability of equipment operation. At the same time, it ensures the tightening force of screw and nut connections, allowing the connected parts to maintain a tight fit.

[0026] Rubber material itself has good sealing properties. When used as a gasket, the rubber gasket 5 can fill the tiny gaps between the upper gasket 1, the lower gasket 2 and the connecting parts, preventing the infiltration of media such as gas and liquid.

[0027] Example 2: To achieve high sealing performance during gasket use, please refer to... Figures 1-4 Based on embodiment 1, an installation groove 11 is provided at the inner end of the inner surface of the upper gasket 1, a sealing ring 12 is bonded to the inner end of the installation groove 11, and an installation ring 13 is provided on the outer side of the installation groove 11.

[0028] The inner end of the inner surface of the lower washer 2 is provided with a mounting ring 23, the outer side of the mounting ring 23 is provided with a mounting groove 21, and a sealing ring 22 is bonded to the inner end of the mounting groove 21.

[0029] Mounting slot 11 corresponds to and is adapted to mounting ring 23, and mounting ring 13 corresponds to and is adapted to mounting slot 21;

[0030] Both the upper washer 1 and the lower washer 2 have wedge-shaped toothed surfaces 6 on their corresponding surfaces.

[0031] Specifically, a sealing ring 12 is bonded to the inner end of the mounting groove 11 of the upper washer 1, and a sealing ring 22 is bonded to the inner end of the mounting groove 21 of the lower washer 2. When the washers are installed and used, because the mounting groove 11 corresponds to and fits the mounting ring 23, and the mounting ring 13 corresponds to and fits the mounting groove 21, the upper washer 1 and the lower washer 2 can be tightly nested together during installation, and the two sealing rings can directly and tightly contact the corresponding mounting rings. Because the sealing rings made of rubber and other materials have good elasticity, they will deform under pressure, filling the tiny gap between the mounting ring and the mounting groove, preventing the entry of gas, liquid, and other media, and thus achieving a sealing function.

[0032] Two sealing rings are respectively set on the inner ends of the inner surfaces of the upper gasket 1 and the lower gasket 2, forming a double sealing structure. Even if one sealing ring is slightly damaged or has a poor seal, the other sealing ring can still ensure the sealing effect to a certain extent, greatly improving the overall sealing reliability.

[0033] Working principle: Place the upper washer 1 and the lower washer 2 on the screw respectively, so that the mounting groove 11 corresponds to the mounting ring 23 and the mounting ring 13 corresponds to the mounting groove 21. Press the upper washer 1 and the lower washer 2 to make them initially nested together. At this time, the wedge-shaped tooth surface 6 contacts each other, and at the same time, the annular rubber pad 5 contacts the surface of the connecting part.

[0034] Tighten the screws and nuts using appropriate tools (such as wrenches). During the tightening process, the upper washer 1 and the lower washer 2 will be subjected to axial pressure, which will cause the wedge-shaped tooth surface 6 to mesh more tightly, increasing the friction and fit between the upper washer 1 and the lower washer 2;

[0035] As the screws and nuts are tightened, the compression between the mounting groove and the mounting ring increases. The sealing ring 12 and sealing ring 22 undergo elastic deformation under pressure, filling the tiny gap between the mounting ring and the mounting groove. At the same time, the annular rubber pad 5 is further compressed, filling the gap between the upper washer 1, the lower washer 2 and the connecting parts.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
