Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic ferrules, and more specifically, to a durable hydraulic ferrule. Background Art

[0002] Hydraulic ferrule is a key component in hydraulic system, mainly used to connect pipes and fittings. Its structure is usually composed of ferrule and joint. Ferrule is a sleeve-shaped part made of metal material with locking groove on the inner wall, which can be locked on pipes or fittings by twisting or compression.

[0003] The hydraulic ferrule plays multiple roles in the hydraulic system. It protects the internal parts of the hydraulic cylinder, prevents leakage or damage caused by wear, and ensures the normal operation of the hydraulic system. The hydraulic ferrule can prevent foreign matter such as impurities from mixing in, avoids parts damage and hydraulic system failure. The existing hydraulic ferrule is fixed by a nut, and is installed by pressing the nut against the rear end of the joint. When the hydraulic ferrule is used for too long, the nut will loosen, which will cause the joint to loosen, resulting in the failure of the hydraulic ferrule, so it needs to be improved.
