Description

Technical Field

[0001] The utility model belongs to the technical field of sealing rings, and in particular relates to a novel anti-aging rubber sealing ring. Background Art

[0002] Sealing rings are materials or parts that prevent fluids or solid particles from leaking from adjacent mating surfaces and prevent external impurities such as dust or moisture from invading components inside machinery and equipment. Sealing rings generally work under certain pressure and temperature conditions. Sealing rings with different structures and materials have different sealing effects under different conditions. However, once the sealing of the sealing ring fails, it will directly affect the use of the equipment.

[0003] For example, an anti-aging rubber seal ring with publication number CN212838981U includes a seal ring body, which is provided with a flame retardant layer, a first strengthening layer, a pressure-resistant layer, and a second strengthening layer in sequence from the outside to the inside, and a self-lubricating layer is provided in the inner cavity of the second strengthening layer, and the flame retardant layer is provided in a strip shape and wound around the outer side of the first strengthening layer, and the pressure-resistant layer includes triangular blocks uniformly distributed along the circumference between the outer side of the second strengthening layer and the inner side of the first strengthening layer, and an elastic block is filled in the gap between the outer side of the second strengthening layer and the inner side of the first strengthening layer. Advantages of the utility model: increased anti-aging and improved service life.

[0004] The rubber sealing rings in the prior art are mostly single-layer rubber ring bodies. When in use, grease needs to be applied on the surface to improve the aging resistance of the sealing ring. However, due to the extrusion of mechanical parts such as fasteners, the grease is likely to overflow from the sealing gasket hole, which makes it impossible for the grease to be effectively stored in the rubber sealing ring, making it impossible for the grease to effectively protect the rubber sealing ring, causing the rubber sealing ring to be prone to aging. Utility Model Content

[0005] The utility model aims to provide a novel anti-aging rubber sealing ring, aiming to solve the problem that the rubber sealing ring in the prior art cannot be effectively lubricated with grease and is prone to aging.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new anti-aging rubber sealing ring, including a sealing ring body, the sealing ring body including: a bottom ring body, a surrounding edge, a pressure-resistant layer, a top ring body and a snap-in groove, the bottom ring body, the pressure-resistant layer and the top ring body are connected in sequence, the snap-in groove is opened on the bottom surface of the top ring body, and the surrounding edge is connected to the surface of the bottom ring body.

[0007] In order to substantially improve the aging resistance of the sealing ring, as a preferred novel aging-resistant rubber sealing ring of the utility model, the bottom ring body, the surrounding edge, the pressure-resistant layer and the top ring body are an integrally formed structure and are made of polyurethane rubber material.

[0008] In order to prevent the grease from overflowing, as a preferred anti-aging rubber sealing ring of the utility model, the position and size of the snap-in groove are matched with the position and size of the surrounding edge, and the top of the surrounding edge can be snapped into the snap-in groove.

[0009] In order to allow the grease to be stored in the gap between the pressure-resistant layer and the surrounding edge, as a preferred novel anti-aging rubber sealing ring of the utility model, the outer edge of the pressure-resistant layer is provided with three layers of continuous wavy semicircular ridges.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model can store the applied grease in the gap between the surrounding edge and the pressure-resistant layer through the mutual cooperation between the surrounding edge, the pressure-resistant layer and the snap-in groove. At the same time, the grease can be blocked and prevented from overflowing through the snap-in between the surrounding edge and the snap-in groove, so that the grease can penetrate the entire sealing ring well, effectively improving the anti-aging effect of the sealing ring.

[0012] 2. The utility model can not only realize multi-layer sealing of the sealing ring and improve the sealing performance by setting the bottom ring body, the pressure-resistant layer and the top ring body, but also improve the pressure resistance of the entire sealing ring, effectively reduce the compression deformation of the sealing ring, prevent the rubber ring from cracking, increase the service life, and further enhance the anti-aging effect.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a new anti-aging rubber sealing ring, including a sealing ring body 1, the sealing ring body 1 includes: a bottom ring body 101, a surrounding edge 102, a pressure-resistant layer 103, a top ring body 104 and a snap-in groove 105, the bottom ring body 101, the pressure-resistant layer 103 and the top ring body 104 are connected in sequence, the snap-in groove 105 is opened on the bottom surface of the top ring body 104, and the surrounding edge 102 is connected to the surface of the bottom ring body 101.

[0022] Preferably, the bottom ring body 101, the surrounding edge 102, the pressure-resistant layer 103 and the top ring body 104 are an integrally formed structure and are made of polyurethane rubber material.

[0023] When used specifically, polyurethane rubber is a series of elastomeric materials containing a large number of carbamate groups on the polymer main chain, and has the characteristics of good strength, high elasticity, high wear resistance, tear resistance, and aging resistance. The entire sealing ring body 1 is integrally formed by an injection mold, which essentially improves the anti-aging effect.

[0024] Preferably, the position and size of the snap-in groove 105 are matched with the position and size of the surrounding edge 102 , and the top of the surrounding edge 102 can be snapped into the snap-in groove 105 .

[0025] During specific use, after the grease 2 is applied to the anti-pressure layer 103 , the surrounding edge 102 is clipped into the clip groove 105 to effectively limit the overflow of the grease 2 , so that the grease 2 can be well stored to lubricate the sealing ring body 1 .

[0026] Preferably, the outer edge of the pressure-resistant layer 103 is provided with three layers of continuous wavy semicircular protrusions.

[0027] During specific use, the three-layer protrusion of the pressure-resistant layer 103 can improve the deformation capacity like a spring when under pressure, reduce the deformation degree of the sealing ring body 1, and form a good fat storage channel through the intervals of its wavy lines.

[0028] Working principle: When using the new anti-aging rubber sealing ring, push aside the surrounding edge 102, apply the grease 2 evenly to the gap between the pressure-resistant layer 103 and the surrounding edge 102, and then insert the top end of the surrounding edge 102 into the clamping groove 105 to form a closure. Figure 5As shown, the entire sealing ring body 1 is finally placed at the desired position for use. The grease 2 continuously infiltrates the sealing ring body 1, and the anti-deformation force of the pressure-resistant layer 103 can effectively improve the anti-aging effect of the entire sealing ring body 1, thereby increasing the service life of the sealing ring body 1.
