Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a highly flexible rubber sealing ring for sealing electronic devices. Background Technology

[0002] A sealing ring is a sealing element used to prevent liquids, gases, or particles from leaking from equipment, pipes, or mechanical parts. It forms a tight seal by elastically deforming and fitting closely to the contact surface, creating a sealing barrier. Sealing rings are widely used in industrial equipment, hydraulic systems, and electronic equipment. In electronic equipment, sealing rings primarily prevent external environmental factors (such as moisture, dust, and chemicals) from entering the electronic equipment, protecting the stability and safety of electronic components.

[0003] Based on the above, the following problems were found: Current sealing rings used for sealing electronic devices generally suffer from insufficient flexibility, poor deformation recovery ability, and lack of internal support structure. Under long-term compression or dynamic load, they are prone to permanent deformation or torsion, resulting in a decrease in sealing effect. They cannot meet the requirements of electronic devices for sealing reliability and durability, and are inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a highly flexible rubber sealing ring for sealing electronic devices, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a highly flexible rubber sealing ring for sealing electronic devices, in order to solve the problems mentioned in the background art.

[0006] A highly flexible rubber sealing ring for sealing electronic devices includes a sealing ring assembly. The sealing ring assembly includes a ring body with a hollow annular structure. A cavity is formed inside the ring body, and a reinforcing rib is provided in the middle of the inner side of the cavity. A reinforcing ring is fixedly installed inside the reinforcing rib.

[0007] By adopting the above technical solution, the cavity inside the ring body allows the sealing ring to deform under compression or tension, enhancing its flexibility. The cavity structure can absorb external impacts or vibrations, reducing stress concentration. The reinforcing ribs help prevent the ring body from twisting or collapsing under high pressure or dynamic loads. The distribution of the reinforcing ribs evenly transmits local pressure to the entire ring body. The reinforcing ring helps resist shear forces during installation or deformation under long-term compression.

[0008] Furthermore, the sealing ring assembly is made of liquid silicone material, specifically liquid silicone of a platinum catalytic system.

[0009] By adopting the above technical solution, the sealing ring assembly is made of liquid silicone material. Liquid silicone has a low elastic modulus and a wide temperature range adaptability, which makes it easy to meet the high and low temperature working environment of electronic equipment.

[0010] Furthermore, the reinforcing filler of the sealing ring assembly is nano-sized fumed silica.

[0011] By adopting the above technical solution and using nano-grade fumed silica as the reinforcing filler, the mechanical properties of the sealing ring assembly can be enhanced, the tensile strength and tear resistance can be improved, and the risk of seal failure caused by insufficient rebound after long-term compression can be reduced.

[0012] Furthermore, the reinforcing ring has a ring structure, and the thickness of the top and bottom ends of the reinforcing ring is greater than the thickness of the middle part.

[0013] By adopting the above technical solution, and by making the reinforcing ring a ring structure, it is easy to deform synchronously with the ring body, thus avoiding uneven stress caused by independent support points.

[0014] Furthermore, the reinforcing ring is made of a high molecular network polymer.

[0015] By adopting the above technical solution, the reinforcing ring is made of a high molecular network polymer, which facilitates the combination of flexibility and rigidity and avoids the risk of brittle fracture.

[0016] Furthermore, planar protrusions are provided at both the top and bottom of the ring body.

[0017] By adopting the above technical solution, the planar protrusions facilitate engagement with the equipment grooves, prevent the device from shifting during vibration, and compensate for the small gaps in the main sealing surface.

[0018] Furthermore, the inner and outer sides of the ring are provided with two lip pieces, which face the top and bottom ends respectively.

[0019] By adopting the above technical solution and setting the lip, redundant seals can be formed, actively contacting the sealing surface and improving sealing performance.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: the cavity inside the ring body allows the sealing ring to deform under compression or tension, enhancing its flexibility. The cavity structure can absorb external impacts or vibrations, reducing stress concentration. The reinforcing ribs prevent the ring body from twisting or collapsing under high pressure or dynamic loads. The distribution of the reinforcing ribs evenly transmits local pressure to the entire ring body. The reinforcing ring helps resist shear forces during installation or deformation under long-term compression. This utility model has high flexibility and elasticity, is suitable for the small spaces of electronic devices, provides excellent sealing performance, and has a long service life, making it highly practical.

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.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a high-flexibility rubber sealing ring for sealing electronic devices, including a sealing ring assembly 1. The sealing ring assembly 1 includes a ring body 11, which has a hollow annular structure. A cavity 12 is provided inside the ring body 11. The cavity 12 inside the ring body 11 allows the sealing ring to deform under compression or tension, enhancing its flexibility. The cavity structure can absorb external impacts or vibrations, reducing stress concentration. A reinforcing rib 13 is provided in the middle of the inner side of the cavity 12. The reinforcing rib 13 helps prevent the ring body 11 from twisting or collapsing under high pressure or dynamic load. The reinforcing rib 13 distributes local pressure evenly to the entire ring body 11. A reinforcing ring 2 is fixedly installed inside the reinforcing rib 13. The reinforcing ring 2 helps resist shear force during installation or deformation under long-term compression.

[0029] The sealing ring assembly 1 is made of liquid silicone material, which is a liquid silicone material of platinum catalyst system. Since the sealing ring assembly 1 is made of liquid silicone material, the catalyst is preferably chloroplatinic acid, and the dosage ratio is 0.01%~0.1%. Liquid silicone has a low elastic modulus and a wide temperature range adaptability, which is convenient to meet the high and low temperature working environment of electronic equipment.

[0030] Among them, the reinforcing filler of the sealing ring assembly 1 is nano-grade fumed silica. The reinforcing filler is nano-grade fumed silica, with an addition ratio of 10%~30%. The dispersion process is ultrasonic-assisted dispersion, which facilitates the enhancement of the mechanical properties of the sealing ring assembly 1, improves tensile strength and tear resistance, and reduces the risk of sealing failure caused by insufficient rebound after long-term compression.

[0031] Among them, the reinforcing ring 2 is a ring structure, and the thickness of the top and bottom ends of the reinforcing ring 2 is greater than the thickness of the middle part. By making the reinforcing ring 2 a ring structure, it is easy to deform synchronously with the ring body 11, and to avoid uneven stress caused by independent support points.

[0032] Among them, the reinforcing ring 2 is made of a high molecular network polymer. The specific material of the high molecular network polymer is preferably polyurethane, with an elastic modulus ≥50 MPa, which facilitates the combination of flexibility and rigidity and avoids the risk of brittle fracture.

[0033] The ring body 11 has planar protrusions 14 at both the top and bottom. The planar protrusions 14 facilitate engagement with the equipment groove, prevent the device from shifting during vibration, and compensate for the small gaps in the main sealing surface.

[0034] The ring body 11 has two lips 15 on both the inner and outer sides, with the two lips 15 facing the top and bottom respectively. The arrangement of the lips 15 facilitates the formation of redundant seals, actively contacts the sealing surface, and improves the sealing performance.

[0035] Specifically, the working principle of this high-flexibility rubber sealing ring for electronic equipment is as follows: During use, the ring body 11 has a cavity 12 inside, which allows the sealing ring to deform under compression or tension, enhancing its flexibility. The cavity structure can absorb external impacts or vibrations, reducing stress concentration. The reinforcing ribs 13 help prevent the ring body 11 from twisting or collapsing under high pressure or dynamic load. The distribution of the reinforcing ribs 13 evenly transmits local pressure to the entire ring body 11. The reinforcing ring 2 helps resist shear force during installation or deformation under long-term compression. The planar protrusions 14 facilitate engagement with the equipment groove, preventing the device from shifting during vibration and compensating for small gaps in the main sealing surface. The lip 15 facilitates the formation of redundant seals, actively contacting the sealing surface and improving sealing performance.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
