[0002] In industrial production, mechanical equipment connection and various fluid transmission systems, metal hose is widely used because of its good flexibility and corrosion resistance. In particular, the threaded shockproof metal hose not only has the general advantages of metal hose, but also enhances the shockproof and wear-resistant performance through its unique structural design, so that it performs well in complex and changeable working environment. The existing threaded shockproof metal hose usually includes a metal hose body, a connecting structure at both ends of the body for connecting other components, and an outer protective pipe and an inner protective pipe arranged to enhance the protection effect. The inner protective pipe is connected to the outer protective pipe through a first spring, effectively absorbing external vibration and protecting the metal hose body. At the same time, the metal hose body is provided with a protective layer on the inner side, further improving its shock absorption and buffering capacity and durability, and reducing the risk of rupture caused by vibration.

[0003] However, although this type of threaded shockproof metal hose performs well in ductility, wear resistance and shock protection, there are still some problems to be solved in actual use. In particular, the connecting head part in the connecting structure often lacks effective filtering mechanism. After long-term use, impurities, particulate matter and other impurities in the fluid can easily flow into the interior of the metal hose and gradually adhere to the inner wall of the hose. The accumulation of these impurities not only affects the transmission efficiency of the fluid, but also may cause wear and tear to the inner wall of the metal hose, thus shortening its service life. Therefore, we propose a threaded shockproof metal hose to solve the above problems. SUMMARY
