Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe joints, in particular to an oil pipe joint with a protective function. Background Art

[0002] Oil pipe joints, also known as hydraulic joints or oil pipe connectors, are professional connecting components used to connect oil pipes in hydraulic systems to ensure smooth flow of oil and no leakage. Hydraulic systems are widely used in industrial equipment, construction machinery, automobiles, ships and other fields, and oil pipe joints are one of the key accessories.

[0003] However, the prior art has the following disadvantages when in use: the existing oil pipe joint is located for easy steering and is made of rubber, but the rubber is easily damaged when it encounters collision with other objects or sharp objects, and has no protective function. In addition, when the existing oil pipe joint is disassembled for maintenance, it is easy for other debris to stick to it due to the presence of oil at the interface. The debris adheres to the oil, which increases the difficulty of cleaning and is not conducive to keeping the inside of the oil pipe joint clean. Therefore, an oil pipe joint with a protective function is urgently needed to solve the above problems. Utility Model Content
