Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a wear-resistant sealing ring. Background Art

[0002] As a common mechanical part, sealing rings are widely used in various industries. They are often used for dynamic sealing between shafts and holes, mainly to prevent liquid or gas leakage. The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.

[0003] For example, the utility model: "A wear-resistant sealing ring", with the announcement number: "CN213393494U", achieves the purpose of wear resistance through the mutual coordination of the sealing ring body, groove, reinforcement ring, inner ring, protrusion, connecting ring, outer ring and fixed ring, solves the problem that the general sealing ring has a relatively simple structure and poor wear resistance, and can reduce the wear and deformation of the sealing ring during long-term use. However, during the implementation of this patent, when the reinforcement ring is partially cracked due to wear, the inner ring cannot be directly filled into the worn gap of the reinforcement ring, so that the inner side of the sealing ring cannot fit tightly with the object, thereby affecting its sealing performance, and the inner side of the sealing ring is uneven, which is more easily damaged when rubbed with an object. Therefore, the utility model provides a wear-resistant sealing ring to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant sealing ring to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant sealing ring, comprising a rubber sealing ring body, a first mounting groove, a wear-resistant rubber inner ring, a wear-resistant rubber outer ring and a second mounting groove, the inner side of the rubber sealing ring body is provided with a first mounting groove, and the outer side of the rubber sealing ring body is provided with a second mounting groove, the inner side of the rubber sealing ring body is provided with a second wear-resistant filling rubber ring, and the inner side of the second wear-resistant filling rubber ring is provided with a wear-resistant rubber inner ring, the outer side of the rubber sealing ring body is provided with a first wear-resistant filling rubber ring, and the outer side of the first wear-resistant filling rubber ring is provided with a wear-resistant rubber outer ring, the inner side of the first mounting groove is evenly provided with semicircular elastic rubber sheets, and one end of the semicircular elastic rubber sheet away from the rubber sealing ring body is connected to the second wear-resistant filling rubber ring, and the outer side of the wear-resistant rubber inner ring is evenly provided with second wear-resistant filling grooves.

[0006] Preferably, an outer elastic rubber sheet is evenly installed on the inner side of the second installation groove, and one end of the outer elastic rubber sheet away from the rubber sealing ring body is connected to the first wear-resistant filling rubber ring.

[0007] Preferably, first wear-resistant filling grooves are evenly arranged on the inner side of the wear-resistant rubber outer ring.

[0008] Preferably, the cross-section of the outer elastic rubber sheet is in an "S" shape.

[0009] Preferably, twelve groups of semicircular elastic rubber sheets are provided, and the angle between two adjacent groups of semicircular elastic rubber sheets is thirty degrees.

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

[0011] 1. The wear-resistant sealing ring is equipped with a wear-resistant rubber inner ring and a wear-resistant rubber outer ring, which can improve the wear-resistant effect of the rubber sealing ring body, thereby effectively improving the wear resistance of the wear-resistant sealing ring, which is beneficial to prolonging the service life of the wear-resistant sealing ring;

[0012] 2. The wear-resistant sealing ring is equipped with a semicircular elastic rubber sheet and a second wear-resistant filling rubber ring. When in use, the elastic action of the semicircular elastic rubber sheet pushes the second wear-resistant filling rubber ring, so that the second wear-resistant filling rubber ring squeezes the wear-resistant rubber inner ring, so that the wear-resistant rubber inner ring can be closely fitted with the outer side of the object, which can effectively improve the sealing performance. When the wear-resistant rubber inner ring is partially cracked due to wear, the elastic action of the semicircular elastic rubber sheet pushes the second wear-resistant filling rubber ring, so that the second wear-resistant filling rubber ring can be filled into the wear-resistant rubber inner ring through the second wear-resistant filling groove, so that the inner side of the wear-resistant sealing ring can continue to fully fit with the object, avoiding affecting the sealing performance, and the second wear-resistant filling rubber ring and the wear-resistant rubber inner ring can form a firm whole, avoiding the wear-resistant sealing ring from breaking due to wear, which can effectively improve the wear resistance.

[0013] 3. The wear-resistant sealing ring is equipped with a first wear-resistant filling rubber ring and an outer elastic rubber sheet. When the outer side of the wear-resistant sealing ring is squeezed, the outer elastic rubber sheet can be stretched and contracted under force and can help the wear-resistant sealing ring to recover, which can effectively improve the tensile resistance of the wear-resistant sealing ring. When the wear-resistant rubber outer ring is partially cracked due to wear, the elastic action of the outer elastic rubber sheet pushes the first wear-resistant filling rubber ring, so that the first wear-resistant filling rubber ring can be filled into the wear-resistant rubber outer ring through the first wear-resistant filling groove, so that the first wear-resistant filling rubber ring and the wear-resistant rubber outer ring can form a solid whole, avoiding the wear-resistant sealing ring from breaking due to wear, and effectively improving the wear resistance.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-3 The utility model provides an embodiment: a wear-resistant sealing ring, comprising a rubber sealing ring body 1, a first mounting groove 2, a wear-resistant rubber inner ring 6, a wear-resistant rubber outer ring 7 and a second mounting groove 10, the first mounting groove 2 is provided on the inner side of the rubber sealing ring body 1, and the second mounting groove 10 is provided on the outer side of the rubber sealing ring body 1, a second wear-resistant filling rubber ring 5 is installed on the inner side of the rubber sealing ring body 1, and a wear-resistant rubber inner ring 6 is installed on the inner side of the second wear-resistant filling rubber ring 5, a first wear-resistant filling rubber ring 4 is installed on the outer side of the rubber sealing ring body 1, and a wear-resistant rubber outer ring 7 is installed on the outer side of the first wear-resistant filling rubber ring 4, a semicircular elastic rubber sheet 3 is evenly installed on the inner side of the first mounting groove 2, and one end of the semicircular elastic rubber sheet 3 away from the rubber sealing ring body 1 is all in contact with the second wear-resistant filling rubber ring 5, the elastic action of the semicircular elastic rubber sheet 3 pushes the second wear-resistant filling rubber ring 5, so that the second wear-resistant filling rubber ring 5 squeezes the wear-resistant rubber inner ring 6, so that the wear-resistant rubber inner ring 6 can be closely fitted with the outside of the object, which can effectively improve the sealing performance, and the outside of the wear-resistant rubber inner ring 6 is evenly provided with second wear-resistant filling grooves 9. When the wear-resistant rubber inner ring 6 is partially cracked due to wear, the elastic action of the semicircular elastic rubber sheet 3 pushes the second wear-resistant filling rubber ring 5, so that the second wear-resistant filling rubber ring 5 can be filled into the wear-resistant rubber inner ring 6 through the second wear-resistant filling grooves 9, so that the inner side of the wear-resistant sealing ring can continue to fully fit with the object, avoiding affecting the sealing performance, and can make the second wear-resistant filling rubber ring 5 and the wear-resistant rubber inner ring 6 form a firm whole, avoiding the wear-resistant sealing ring from breaking due to wear, which can effectively improve the wear resistance.

[0020] In this implementation:

[0021] Furthermore, an external elastic rubber sheet 11 is evenly installed on the inner side of the second mounting groove 10, and one end of the external elastic rubber sheet 11 away from the rubber sealing ring body 1 is connected to the first wear-resistant filling rubber ring 4. When the outer side of the wear-resistant sealing ring is squeezed, the external elastic rubber sheet 11 can be stretched and contracted under force, and can help the wear-resistant sealing ring to recover, which can effectively improve the tensile resistance of the wear-resistant sealing ring.

[0022] Furthermore, the inner side of the wear-resistant rubber outer ring 7 is evenly provided with a first wear-resistant filling groove 8. When the wear-resistant rubber outer ring 7 is partially cracked due to wear, the elastic action of the external elastic rubber sheet 11 pushes the first wear-resistant filling rubber ring 4, so that the first wear-resistant filling rubber ring 4 can be filled into the wear-resistant rubber outer ring 7 through the first wear-resistant filling groove 8, so that the first wear-resistant filling rubber ring 4 and the wear-resistant rubber outer ring 7 can form a solid whole, thereby avoiding the wear-resistant sealing ring from breaking due to wear, and effectively improving the wear resistance.

[0023] Furthermore, the cross-section of the outer elastic rubber sheet 11 is in an “S” shape.

[0024] Furthermore, twelve groups of semicircular elastic rubber sheets 3 are provided, and the angle between two adjacent groups of semicircular elastic rubber sheets 3 is thirty degrees.

[0025] Working principle:

[0026] When in use, the wear-resistant rubber inner ring 6 on the inner side of the rubber sealing ring body 1 contacts the object, and the elastic action of the semicircular elastic rubber sheet 3 pushes the second wear-resistant filling rubber ring 5, so that the second wear-resistant filling rubber ring 5 squeezes the wear-resistant rubber inner ring 6, so that the wear-resistant rubber inner ring 6 can fit closely with the outer side of the object, which can effectively improve the sealing performance;

[0027] During use, if the wear-resistant rubber inner ring 6 is partially cracked due to friction with an object, the elastic effect of the semicircular elastic rubber sheet 3 pushes the second wear-resistant filling rubber ring 5, so that the second wear-resistant filling rubber ring 5 can be filled into the wear-resistant rubber inner ring 6 through the second wear-resistant filling groove 9, so that the inner side of the wear-resistant sealing ring can continue to fully fit with the object to avoid affecting the sealing performance, and the second wear-resistant filling rubber ring 5 and the wear-resistant rubber inner ring 6 can form a firm whole to avoid the wear-resistant sealing ring from breaking due to wear, which can effectively improve the wear resistance;

[0028] At the same time, if the wear-resistant rubber outer ring 7 on the outside of the rubber sealing ring body 1 is cracked due to friction with an object, the elastic action of the outer elastic rubber sheet 11 pushes the first wear-resistant filling rubber ring 4, so that the first wear-resistant filling rubber ring 4 can be filled into the wear-resistant rubber outer ring 7 through the first wear-resistant filling groove 8, so that the first wear-resistant filling rubber ring 4 and the wear-resistant rubber outer ring 7 can form a firm whole, avoiding the wear-resistant sealing ring from breaking due to wear, and effectively improving the wear resistance;

[0029] Furthermore, during use, if the outer side of the wear-resistant sealing ring is squeezed, the outer elastic rubber sheet 11 can be stretched and contracted under the force, and can help the wear-resistant sealing ring to recover through its elasticity, which can effectively improve the tensile resistance of the wear-resistant sealing ring.
