Description

Technical Field

[0001] This invention relates to the field of pipe joint technology, specifically a highly elastic rubber vibration damping joint. Background Technology

[0002] In pipeline systems, valves and bends are often used to connect the two ends of the pipeline to facilitate pipeline construction. Among the components used for pipeline connection, rubber vibration damping joints are required for flexible connection of the two ends of the pipeline with relative misalignment. This ensures normal pipeline use while preventing damage to the joint caused by pipeline misalignment. Therefore, to facilitate the construction of pipeline systems, we propose a highly elastic rubber vibration damping joint.

[0003] The existing technology still has the following drawbacks in its use:

[0004] In the use of existing high-elasticity rubber vibration damping joints, when the pipeline is deviated or twisted, the joints made of rubber material are prone to blockage due to excessive deviation, which cannot guarantee the normal transmission of fluid inside the pipeline and affects the stability of the pipeline system.

[0005] The existing high-elasticity rubber vibration damping joints are not ideal for buffering vibrations, which can affect the joint connection when the pipeline vibrates, increasing the probability of leakage at the joint location.

[0006] Therefore, we propose a highly elastic rubber vibration damping joint to solve the existing problems. Summary of the Invention

[0007] The purpose of this invention is to provide a highly elastic rubber shock-absorbing joint to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-elasticity rubber shock-absorbing joint, comprising a flange and a rubber tube, wherein a groove is provided inside the rubber tube, six support rods are fixedly installed inside the groove, several auxiliary rods are fixedly installed between two adjacent support rods, and several elastic sleeves are fixedly installed on the outside of the auxiliary rods, wherein the elastic sleeves are semi-circular hollow tubes, and both the top and bottom of the elastic sleeves are provided with inclined surfaces;

[0009] Flanges are fixedly installed at both ends of the rubber tube.

[0010] Preferably, a snap-fit ​​ring is fixedly installed inside the flange, and the snap-fit ​​ring is fixedly connected to both ends of the rubber tube.

[0011] Preferably, a corrugated pipe is fixedly installed at the end of the flange away from the rubber tube, and the outer diameter of the corrugated pipe is the same as the inner diameter of the rubber tube.

[0012] Preferably, the flange has six threaded holes inside, and fixing bolts are installed inside the threaded holes.

[0013] Preferably, both ends of the support rod and the auxiliary rod are fixedly connected to the inner wall of the rubber tube, and the sides of the support rod and the auxiliary rod are fixedly connected to the rubber tube at their contact points.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention reinforces the rubber tube with elastic sleeves, so that several sets of elastic sleeves support the internal space of the rubber tube. When the rubber tube shifts or twists, the sets of elastic sleeves abut against each other, so that there is always a cavity inside the rubber tube, thereby ensuring that the fluid inside the rubber tube can pass through, so as to ensure the stability of fluid transmission in complex working conditions.

[0016] This invention improves the toughness of the rubber tube by installing several support rods and auxiliary rods inside the rubber tube and installing elastic sleeves between the auxiliary rods. This enhances the rubber tube's cushioning effect against vibration. When the rubber tube is under pressure, the elastic sleeves interact with each other, causing the elastic force and pressure to interact, thereby reducing the pressure on the rubber tube body. This ensures the durability of the device and prevents damage that could affect fluid transmission. Attached Figure Description

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 - Figure 7 As shown, the present invention proposes a high-elasticity rubber vibration damping joint, comprising a flange 1 and a rubber tube 2. The rubber tube 2 has a groove inside, and six support rods 201 are fixedly installed inside the groove. Several auxiliary rods 202 are fixedly installed between adjacent support rods 201. Several elastic sleeves 203 are fixedly installed on the outside of the auxiliary rods 202. The elastic sleeves 203 are semi-circular hollow tubes, and both the top and bottom of the elastic sleeves 203 are provided with bevels. The rubber tube 2 can provide installation positions for surrounding components, and after being connected to a piping system, it can transmit fluid in the pipeline. The diameter of the support rods 201 is larger than that of the auxiliary rods 202. 201 can support the rubber tube 2 to improve the overall pressure resistance of the rubber tube 2, so as to buffer the vibration. The auxiliary rod 202 can assist the support rod 201 in supporting the rubber tube 2 and provide an installation position for the elastic sleeve 203. The elastic sleeve 203 can support the rubber tube 2. On the one hand, when the rubber tube 2 is squeezed, it can keep the internal gap of the rubber tube 2 so that the fluid can be transmitted normally. On the other hand, it can buffer the pressure when the rubber tube 2 is squeezed to ensure the integrity of the rubber tube 2 and prevent the device from being damaged. It can also prevent the fluid inside the device from leaking from the inside of the device or the joint.

[0027] Flanges 1 are fixedly installed at both ends of the rubber hose 2. Flanges 1 facilitate the connection of the device with other pipes, thereby improving the stability and sealing of the connection between pipes.

[0028] Furthermore, a snap ring 103 is fixedly installed inside the flange 1, and the snap ring 103 is fixedly connected to both ends of the rubber tube 2. The snap ring 103 can fix the two ends of the rubber tube 2 to the flange 1, which on the one hand ensures the connection stability between the rubber tube 2 and the flange 1, and on the other hand prevents the fluid inside the rubber tube 2 from leaking from the snap ring 103.

[0029] Furthermore, a bellows 102 is fixedly installed at the end of the flange 1 away from the rubber tube 2. The outer diameter of the bellows 102 is the same as the inner diameter of the rubber tube 2. The bellows 102 can be inserted into the interior of the external pipe. During the installation process, by bringing the pipe openings close together, the bellows 102 is squeezed, which seals the joint of the bellows 102, improves the sealing performance at the pipe connection, and prevents internal fluid leakage caused by excessive pressure at the pipe opening.

[0030] Furthermore, the flange 1 has six threaded holes inside, and fixing bolts 101 are installed inside the threaded holes. The fixing bolts 101 can easily connect the flanges 1 to each other, thereby ensuring the connection stability between the device and the external pipeline.

[0031] Furthermore, both ends of the support rod 201 and the auxiliary rod 202 are fixedly connected to the inner wall of the rubber tube 2, and the sides of the support rod 201 and the auxiliary rod 202 are fixedly connected to the rubber tube 2 at the contact points.

[0032] Working principle: After the device is assembled, align the flanges 1 at both ends of the rubber tube 2 with the flanges 1 of the external pipe, and connect the flanges 1 to each other using fixing bolts 101, so that the device is connected to the pipeline system to connect the two sets of pipes. When the device is squeezed or twisted, the elastic sleeve 203 supports the inside of the rubber tube 2, allowing the fluid to be transmitted through the gap between the rubber tube 2 and the elastic sleeve 203. The elasticity of the elastic sleeve 203 interacts with the pressure on the rubber tube 2, reducing the damage to the rubber tube 2 and ensuring the overall integrity of the device and the stability during operation.

[0033] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
