Anti-falling rubber sealing ring

Abstract

This utility model relates to the field of rubber sealing ring technology and discloses an anti-detachment rubber sealing ring, including a ring cover, a retaining ring fixedly connected to the bottom side of the ring cover, a sealing ring fixedly connected to the outer wall of the bottom center of the ring cover, and a semi-circular protrusion fixedly connected to the outer wall of the sealing ring. When the sealing ring needs to be used, the operator first inserts the sealing ring into the through groove inside the pipe and presses down the ring cover, causing the retaining ring and the sealing ring to move downwards. This causes the outer wall of the semi-circular protrusion to press against the inner wall of the pipe. After the sealing ring enters the pipe, the outer wall of the semi-circular protrusion presses against the inside of the pipe, and the inner wall of the retaining ring presses against the outer wall of the pipe, thus fixing the sealing ring to the pipe and preventing it from falling off, improving the sealing performance of the sealing ring. By setting multiple semi-circular protrusions, the sealing ring can be fixed after the multiple semi-circular protrusions press against the outer wall of the pipe.

Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically an anti-detachment rubber sealing ring. Background Technology

[0002] Construction machinery cannot function without hydraulic cylinders, and hydraulic cylinders cannot function without seals. The most common seal is the sealing ring, also called an oil seal, which isolates the oil and prevents oil from overflowing or passing through. Common types of sealing rings used in hydraulic cylinders include: dust rings, piston rod seals, buffer seals, guide support rings, end cap seals, and piston seals. Buffer seals, as auxiliary piston rod seals, are used to protect the piston rod when the system pressure suddenly increases. There are three common types of buffer seals, which are used to prevent seal compression and allow the seal to withstand higher pressure.

[0003] In existing technologies, when a sealing ring is needed to seal a pipeline, the operator inserts the sealing ring into the inner wall of the pipeline end face, so that the inner wall of the sealing ring fits against the inner wall of the pipeline, thereby achieving a seal on the pipeline.

[0004] Existing sealing rings still have some shortcomings. Their structure is too simple, and they are easily damaged by compression when the pipeline pressure suddenly increases during use, thus reducing their sealing performance. To address this, we propose an anti-detachment rubber sealing ring. Utility Model Content

[0005] The purpose of this invention is to provide an anti-detachment rubber sealing ring, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment rubber sealing ring, comprising a ring cover, a retaining ring fixedly connected to the bottom side of the ring cover, a sealing ring fixedly connected to the outer wall of the bottom center of the ring cover, and a semi-circular protrusion fixedly connected to the outer wall of the sealing ring. When the sealing ring needs to be used, the operator first inserts the sealing ring into the through groove inside the pipe and presses down the ring cover, causing the retaining ring and the sealing ring to move downwards. This causes the outer wall of the semi-circular protrusion to press against the inner wall of the pipe. After the sealing ring enters the pipe, the pressure exerted by the outer wall of the semi-circular protrusion against the inside of the pipe, combined with the pressure exerted by the inner wall of the retaining ring against the outer wall of the pipe, effectively fixes the sealing ring to the pipe, preventing the sealing ring from detaching and improving the sealing performance of the sealing ring on the pipe.

[0007] Preferably, there are several semicircular protrusions, which are evenly distributed on the outer wall of the sealing ring. By setting multiple semicircular protrusions, the sealing ring can be fixed after the multiple semicircular protrusions compress the outer wall of the pipe.

[0008] Preferably, the outer wall of the locking ring is further provided with a protective coating. The protective coating includes a heat insulation layer fixedly connected to the inner wall of the left side of the protective coating, a pressure-resistant layer fixedly connected to the side wall of the heat insulation layer, and a wear-resistant layer fixedly connected to the right side of the pressure-resistant layer. The right side of the wear-resistant layer is fixedly connected to the right side of the inner wall of the protective coating. By providing a protective coating on the outer wall of the locking ring, the protective coating includes a heat insulation layer, a pressure-resistant layer, and a wear-resistant layer. The heat insulation layer can improve the heat insulation performance of the locking ring and the sealing ring. The pressure-resistant layer can improve the pressure resistance performance of the locking ring. The wear-resistant layer can improve the wear resistance performance of the wear-resistant layer of the locking ring.

[0009] Preferably, the bottom outer wall of the sealing ring is chamfered.

[0010] Preferably, the bottom inner wall of the locking ring is chamfered.

[0011] Preferably, the inner diameter of the sealing ring is the same as the inner diameter of the ring cover.

[0012] This invention provides an anti-detachment rubber sealing ring. This anti-detachment rubber sealing ring has the following beneficial effects: (1) When the anti-detachment rubber sealing ring needs to be used, the operator first inserts the sealing ring into the through groove inside the pipe and presses down the ring cover to make the locking ring and the sealing ring move downward, thereby causing the semi-circular convex outer wall to squeeze the inner wall of the pipe. After the sealing ring enters the inside of the pipe, it squeezes the inside of the pipe through the semi-circular convex outer wall and then squeezes the outer wall of the pipe together with the inner wall of the locking ring, thus fixing the sealing ring to the pipe, preventing the sealing ring from falling off, and improving the sealing performance of the sealing ring to the pipe. (2) The anti-detachment rubber sealing ring has a protective coating on the outer wall of the locking ring. The protective coating includes a heat insulation layer, a pressure-resistant layer and a wear-resistant layer. The heat insulation layer can improve the heat insulation performance of the locking ring and the sealing ring. The pressure-resistant layer can improve the pressure resistance performance of the locking ring. The wear-resistant layer can improve the wear resistance performance of the wear-resistant layer of the locking ring. Attached Figure Description

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0017] Example 1 An anti-detachment rubber sealing ring includes a ring cover 1, a retaining ring 2 fixedly connected to the bottom side of the ring cover 1, a sealing ring 3 fixedly connected to the outer wall of the bottom center of the ring cover 1, and a semi-circular protrusion 4 fixedly connected to the outer wall of the sealing ring 3. When the sealing ring 3 needs to be used, the operator first inserts the sealing ring 3 into the through groove inside the pipe and presses down the ring cover 1, causing the retaining ring 2 and the sealing ring 3 to move downwards, thereby causing the outer wall of the semi-circular protrusion 4 to squeeze the inner wall of the pipe. After the sealing ring 3 enters the inside of the pipe, the outer wall of the semi-circular protrusion 4 squeezes the inside of the pipe, and the inner wall of the retaining ring 2 squeezes the outer wall of the pipe, thus fixing the sealing ring 3 to the pipe, preventing the sealing ring 3 from falling off, and improving the sealing performance of the sealing ring 3 to the pipe. There are several semi-circular protrusions 4, which are evenly distributed on the outer wall of the sealing ring 3. By setting multiple semi-circular protrusions 4, the sealing ring 3 can be fixed after the multiple semi-circular protrusions 4 press against the outer wall of the pipe. The bottom outer wall of sealing ring 3 is chamfered; The bottom inner wall of the locking ring 2 is chamfered; The inner diameter of the sealing ring 3 is the same as the inner diameter of the ring cover 1.

[0018] Example 2 The difference from Example 1 is that this example discloses a protective coating, such as... Figure 4 As shown: The outer wall of the locking ring 2 is also provided with a protective coating 51. The protective coating 51 includes a heat insulation layer 511 fixedly connected to the inner wall of the left side of the protective coating 51. A pressure-resistant layer 512 is fixedly connected to the side wall of the heat insulation layer 511. A wear-resistant layer 513 is fixedly connected to the right side of the pressure-resistant layer 512. The right side of the wear-resistant layer 513 is fixedly connected to the right side of the inner wall of the protective coating 51. By providing the protective coating 51 on the outer wall of the locking ring 2, which includes a heat insulation layer 511, a pressure-resistant layer 512, and a wear-resistant layer 513, the heat insulation layer 511 can improve the heat insulation performance of the locking ring 2 and the sealing ring 3. The pressure-resistant layer 512 can improve the pressure resistance performance of the locking ring 2. The wear-resistant layer 513 can improve the wear resistance performance of the wear-resistant layer 513 of the locking ring 2.

[0019] Working principle: When the sealing ring 3 needs to be used, the operator first inserts the sealing ring 3 into the through groove inside the pipe and presses down the ring cover 1, causing the locking ring 2 and the sealing ring 3 to move downwards. This causes the outer wall of the semi-circular protrusion 4 to squeeze the inner wall of the pipe. After the sealing ring 3 enters the inside of the pipe, the outer wall of the semi-circular protrusion 4 squeezes the inside of the pipe, and the inner wall of the locking ring 2 squeezes the outer wall of the pipe, thus fixing the sealing ring 3 to the pipe, preventing the sealing ring 3 from falling off, and improving the sealing performance of the sealing ring 3 to the pipe. The protective coating 51 provided on the outer wall of the locking ring 2 includes a heat insulation layer 511, a pressure-resistant layer 512, and a wear-resistant layer 513. The heat insulation layer 511 can improve the heat insulation performance of the locking ring 2 and the sealing ring 3. The pressure-resistant layer 512 can improve the pressure resistance of the locking ring 2. The wear-resistant layer 513 can improve the wear resistance of the wear-resistant layer 513 of the locking ring 2.
