[0022] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0023] See Figures 1-4 , the utility model provides a technical solution:

[0024] A vibration-resistant insulating joint includes a first connecting end 1, a connecting tube 2, a second connecting end 3, an anti-vibration fastening insulating pressure ring 4, and a sealing gasket 5. One end of the connecting tube 2 is sealed and fixedly connected to the second connecting end 3. A stepped ring is fixedly provided on the other end of the connecting tube 2. A first stepped hole is provided in the first connecting end 1. An anti-vibration fastening insulating pressure ring 4 is provided between the stepped ring and the first stepped hole. A through mounting port is provided on the side wall of the anti-vibration fastening insulating pressure ring 4. The sealing gasket 5 is provided in the first stepped hole and cooperates with the end of the connecting tube 2. Among them, the connecting tube 2 serves as the main part of the connection structure and is responsible for connecting the first connecting end 1 with the second connecting end 3. The stepped ring provided on one end of the connecting tube 2 cooperates with the first stepped hole in the first connecting end 1 to enhance the stability of the connection and the sealing effect. The anti-vibration fastening insulating pressure ring 4 is installed between the stepped ring and the first stepped hole to play the role of fastening, vibration resistance, and insulation. The sealing gasket 5 is arranged in the first stepped hole and cooperates with the end of the connecting pipe 2 to play a sealing role, ensuring the sealing between the connecting pipe 2 and the first connecting end 1 and preventing fluid or gas from leaking at the connection.

[0025] In some embodiments, the width of the mounting opening is 4-5 mm. The width design of the mounting opening helps reduce errors during installation and ensures that the anti-vibration fastening insulating pressure ring 4 can be correctly and securely installed between the step ring and the first step hole, thereby enhancing the fastening, vibration resistance, and insulation effects of the connection.

[0026] In some embodiments, the second connection terminal 3 is provided with a second stepped hole, and the connection tube 2 is disposed in and mated with the second stepped hole. The second stepped hole provides a precise docking position for the connection tube 2, ensuring that the connection tube 2 can be accurately installed in the second connection terminal 3, avoiding the problem of loose connection due to position deviation.

[0027] In some embodiments, a clearance fit is provided between the end of the connecting tube 2 and the bottom of the second stepped hole. This clearance fit prevents direct contact between the connecting tube 2 and the bottom of the second stepped hole, reducing friction and wear caused by movement. It also provides greater flexibility when adjusting the position or angle of the connecting tube 2. During actual manufacturing, the dimensions of the connecting tube 2 and the second stepped hole may vary. The clearance fit compensates for these manufacturing variations, ensuring the proper function and performance of the connection structure.

[0028] In some embodiments, the distance between the end of the connecting tube 2 and the bottom of the second stepped hole is a = 1-1.5 mm. This clearance control helps ensure that the fit between the connecting tube 2 and the second stepped hole is neither too tight nor too loose, thereby ensuring a stable and reliable connection. It also reduces direct contact between the connecting tube 2 and the bottom of the second stepped hole during relative movement, thereby reducing friction and wear. When maintenance or replacement of the connecting tube 2 is required, this clearance also provides more operating space, facilitating removal and installation.

[0029] In some embodiments, the connecting tube 2 and the second connecting terminal 3 are securely connected via a welded seal. This welded connection strengthens the connection between the connecting tube 2 and the second connecting terminal 3, making the entire structure more secure and stable. Improving system safety: The sealing performance and robustness of welded connections contribute to improved overall system safety. In industries such as chemical, petroleum, and natural gas, system safety is directly related to production safety and environmental protection. Using welded connections can reduce the risk of leaks and accidents, improving overall system safety.

[0030] In some embodiments, when the first connection terminal 1 contacts the second connection terminal 3, the end of the connection tube 2 extends 2-4 mm outside the end of the first connection terminal 1. During installation and commissioning, the extended portion of the connection tube 2 can serve as a reference point, helping workers more accurately position and secure the connection terminals. It also facilitates adjustment and replacement of the anti-tightening insulating pressure ring 4, simplifying the installation process, improving installation efficiency, and reducing problems caused by improper installation.

[0031] In some embodiments, the anti-vibration fastening insulating pressure ring 4 is an insulating rubber ring, which is a prior art.

[0032] Principle: Reduce installation requirements, ensure that the joint is not damaged during transportation and assembly, and will not fall off due to loosening. The anti-vibration fastening will produce resonance to play an anti-vibration role. At the same time, the second connection terminal 3 outside the connector and the first connection terminal 1 will be connected more tightly, which can effectively prevent falling off. The anti-vibration fastening should be longer than the first connection terminal 1, so that the opening can also be observed with the naked eye. You can intuitively see whether the first connection terminal 1 at the flexible joint connection and the second connection terminal 3 outside the connector are tightened, and can be disassembled and replaced through the 4mm opening expansion, which makes the operation simpler, more convenient and safer.
