Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a rubber ring used in combination. Background Technology

[0002] A rubber ring is a ring-shaped sealing part made of rubber that can seal pipes and equipment that requires sealing. It generally has properties such as elasticity, wear resistance, high temperature resistance, and cold resistance, and is widely used in various mechanical and industrial fields.

[0003] Rubber sealing rings are prone to material aging after a certain period of use in harsh environments. Once the aged rubber ring loses its elasticity, leakage is likely to occur. Existing technology discloses a combined rubber sealing ring, in which the rebound force generated by the compression and bending of an annular spring acts on the rubber ring to hold it in place, allowing the rubber ring to maintain its expansion within a certain range of aging and continue to seal. However, the elasticity of the annular spring deteriorates after long-term use, thus reducing the elastic force exerted on the rubber ring; moreover, the reduced elasticity of the annular spring cannot be restored, resulting in a poor sealing effect of the rubber ring and ultimately rendering the entire rubber ring unusable. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a rubber ring for combined use, which can provide elastic force to the rubber ring through an elastic element, so that the rubber ring can still maintain good sealing performance after aging to a certain extent, and the elastic force of the elastic element is adjustable, thereby improving the overall service life of the rubber ring.

[0005] This utility model provides a rubber ring for combined use, comprising:

[0006] Inner rubber ring;

[0007] An outer rubber ring is fitted onto the outer ring side of the inner rubber ring;

[0008] Multiple elastic components are arranged in a circular array on the outer side of the inner rubber ring, wherein,

[0009] The elastic component includes an elastic element and an arc-shaped auxiliary plate. The elastic element includes a threaded rod, an adjusting nut, a connecting plate, and a spring. One end of the threaded rod is fixedly connected to the outer ring side of the inner rubber ring, and the other end extends towards the side close to the outer rubber ring. The adjusting nut is threadedly fitted onto the outside of the threaded rod. The connecting plate is movably fitted onto the outside of the threaded rod and abuts against the adjusting nut. One end of the spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the arc-shaped auxiliary plate. The arc-shaped auxiliary plate abuts against the inner ring side of the outer rubber ring. Rotating the adjusting nut causes the spring to deform.

[0010] Furthermore, each set of the arc-shaped auxiliary plates is connected to multiple sets of elastic elements, and the multiple sets of elastic elements are equally spaced along the arc direction of the arc-shaped auxiliary plate on the concave arc side of the arc-shaped auxiliary plate.

[0011] Furthermore, a limiting plate is fixedly provided at the end of the threaded rod away from the inner rubber ring.

[0012] Furthermore, the inner ring side of the outer rubber ring is provided with a first annular groove for inserting multiple limiting plates.

[0013] Furthermore, the outer ring of the inner rubber ring has two second annular grooves arranged side by side, and the inner ring of the outer rubber ring has two annular retaining strips that engage with the second annular grooves; the elastic component is located between the two second annular grooves.

[0014] Furthermore, the cross-section of the annular strip is teardrop-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention includes an inner rubber ring, an outer rubber ring, and multiple elastic components. The deformation force generated by the compression of the elastic components acts on the outer rubber ring, allowing it to maintain expansion even after a certain degree of aging, thus preserving good sealing performance. This solves the problem of decreased sealing performance due to reduced elasticity of the rubber ring after aging. Furthermore, by rotating the adjusting nut inside the elastic component, the position of the connecting plate can be adjusted, thereby compressing the spring and increasing its elastic force. This restores the elastic force exerted on the outer rubber ring, solving the problem of reduced elasticity of the elastic component due to long-term use. By adjusting the nut to compress the spring, the elastic force of the elastic component is adjusted, thereby extending the service life of the rubber ring.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1-4 The present invention provides a rubber ring for combined use, including an inner rubber ring 1, an outer rubber ring 2 and multiple elastic components 3; wherein, the outer rubber ring 2 is sleeved on the outer ring side of the inner rubber ring 1; the multiple elastic components 3 are arranged in a circular array on the outer ring side of the inner rubber ring 1. Specifically, the present application provides four sets of elastic components 3, which are arranged in a circular array, and the multiple elastic components 3 uniformly provide elastic force to the outer rubber ring 2.

[0030] Preferably, the elastic component 3 includes an elastic element 31 and an arc-shaped auxiliary plate 32. The elastic element 31 includes a threaded rod 311, an adjusting nut 312, a connecting plate 313, and a spring 314. One end of the threaded rod 311 is fixedly connected to the outer ring side of the inner rubber ring 1, and the other end extends towards the side close to the outer rubber ring 2. The adjusting nut 312 is threadedly sleeved on the outside of the threaded rod 311. The connecting plate 313 is movably sleeved on the outside of the threaded rod 311 and abuts against the adjusting nut 312. One end of the spring 314 is fixedly connected to the connecting plate 313, and the other end is fixedly connected to the arc-shaped auxiliary plate 32. The arc-shaped auxiliary plate 32 abuts against the inner ring side of the outer rubber ring 2. Rotating the adjusting nut 312 can cause the spring 314 to deform. Specifically, the connecting plate 313 has a through hole in the center for the threaded rod 311 to pass through, and the arc-shaped auxiliary plate 32 also has a through hole for the threaded rod 311 to pass through. The end of the threaded rod 311 away from the inner rubber ring 1 passes through the adjusting nut 312, the connecting plate 313 and the arc-shaped auxiliary plate 32 in sequence, and the curvature of the outer edge of the arc-shaped auxiliary plate 32 is the same as the curvature of the inner ring side of the outer rubber ring 2.

[0031] In this embodiment, the outer rubber ring 1 is fitted onto the outer ring side of the inner rubber ring 1. The inner ring side of the outer rubber ring 1 abuts against the arc-shaped auxiliary plate 32, thereby compressing the spring 314. The spring 314 deforms due to compression, generating a reaction force on the outer rubber ring 1. This allows the outer rubber ring 1 to maintain expansion even after a certain degree of aging, enabling it to continue to be used for sealing. After long-term use, when the elastic performance of the spring 314 deteriorates, the position of the connecting plate 313 can be adjusted by rotating the adjusting nut 312, thereby compressing the spring 314, increasing its elastic force, and restoring its elastic force on the outer rubber ring 2. This solves the problem of reduced elastic force provided to the outer rubber ring 2 due to the decreased elastic performance of the elastic element 31 after long-term use. By adjusting the nut 312 to compress the spring 314, the elastic force of the elastic element 31 is adjusted, thereby extending the overall service life of the rubber ring.

[0032] In a preferred embodiment, such as Figure 3 As shown, each set of arc-shaped auxiliary plates 32 is connected to multiple sets of elastic elements 31, and the multiple sets of elastic elements 31 are evenly spaced along the arc direction of the arc-shaped auxiliary plate 32 on the concave arc side of the arc-shaped auxiliary plate 32. Specifically, by evenly arranging multiple sets of elastic elements 31, the elastic force provided by the arc-shaped auxiliary plate 32 can be evenly distributed, and the elastic compensation for the aging area of ​​the rubber ring can be flexibly adjusted.

[0033] In a preferred embodiment, such as Figure 3 As shown, a limiting plate 315 is fixedly installed at the end of the threaded rod 311 away from the inner rubber ring 1. Specifically, the limiting plate 315 limits the arc-shaped auxiliary plate to prevent the spring force of the spring 314 from pushing the arc-shaped auxiliary plate away from the threaded rod 311.

[0034] In a preferred embodiment, such as Figure 3 As shown, the inner ring side of the outer rubber ring 2 is provided with a first annular groove 21 for inserting multiple limiting plates 315.

[0035] In this embodiment, when the outer rubber ring 2 is sleeved with the inner rubber ring 1, the limiting plate 315 at the end of the threaded rod 311 is inserted into the first annular groove 21. The threaded rod 311 also serves as a guide, so that the spring 314 can only be compressed and deformed along the length direction of the threaded rod 311, and the elastic force generated by the deformation of the spring 314 is evenly applied to the circumference of the outer rubber ring 2.

[0036] In a preferred embodiment, such as Figure 3 As shown, the outer ring side of the inner rubber ring 1 has two second annular grooves arranged side by side, and the inner ring side of the outer rubber ring 2 has two annular retaining strips 22 that engage with the second annular grooves; the elastic component 3 is located between the two second annular grooves.

[0037] In this embodiment, the inner rubber ring 1 and the outer rubber ring 2 are combined into a whole by engaging with the second annular groove and the annular retaining strip 22. The engagement position is tight, so that the rubber ring as a whole maintains good sealing performance.

[0038] In a preferred embodiment, such as Figure 3 As shown, the cross-section of the annular clip 22 is teardrop-shaped. The structure is relatively stable after snapping.

[0039] Working principle:

[0040] By inserting the annular retaining strip 22 into the second annular groove, the outer rubber ring 1 is stably fitted onto the outer ring side of the inner rubber ring 1. The inner ring side of the outer rubber ring 1 abuts against the arc-shaped auxiliary plate 32, thereby compressing the spring 314. The spring 314 deforms due to compression, generating a reaction force on the outer rubber ring 1, thus allowing the outer rubber ring 1 to maintain expansion even after a certain degree of aging, and continue to be used for sealing. After long-term use, when the elastic performance of the spring 314 deteriorates, the outer rubber ring 2 can be removed, and the position of the connecting plate 313 can be adjusted by rotating the adjusting nut 312, thereby compressing the spring 314, increasing the elastic force of the spring 314, and restoring its elastic force on the outer rubber ring 2. This solves the problem of reduced elastic force provided to the outer rubber ring 2 due to the decreased elastic performance of the elastic element 31 after long-term use. By adjusting the nut 312 to compress the spring 314, the elastic force of the elastic element 31 is adjusted, thereby extending the overall service life of the rubber ring and preventing premature scrapping of the rubber ring.
