Problems solved by technology

[0002] As a commonly used mechanical component, hydraulic cylinders have been widely used in the mechanical field. Existing hydraulic cylinders are equipped with dust-proof rings to block external dust, but during the long-term reciprocating motion of the piston rod, not only the piston rod Exposure to the outside, easy to damage, rust in contact with water, affect performance and shorten service life

Embodiment Construction

[0011] like figure 1 It is a structural schematic diagram of the present invention, a rust-proof hydraulic oil cylinder, including a cylinder body 1, a piston 2, a piston rod 3, a cylinder cover 4 and an oil filling port 5, the piston 2 is placed in the cylinder body 1 and is fixedly connected with the piston rod 3, The oil filling port 5 is located on the cylinder body 1 and communicates with the inner cavity of the cylinder body 1 , and the piston rod 3 is covered with an antirust cylinder 6 . The front end of the anti-rust cylinder 6 is a transition ring 7, and the rear end is an oil chamber 8. Anti-rust oil is housed in the oil chamber 8.

[0012] An antirust cylinder 6 is arranged on the piston rod 3, and antirust oil is housed in the antirust cylinder 6, which can soak the piston rod 3 and play an effective protective role. The transition ring 7 at the front end of the antirust cylinder 6 can play a role The role of sealing and isolation can also be used to smear and w...

Abstract

The invention relates to the technical field of hydraulic devices, in particular to a rust-proof hydraulic cylinder comprising a cylinder body, a piston, a piston rod, a cylinder cover and an oil inlet. The piston is placed in the cylinder body and is fixedly connected with the piston rod, the oil inlet is formed in the cylinder body and is communicated with the cylinder cavity, and the piston rod is sleeved with a rust proofing sleeve. The rust proofing sleeve is arranged on the piston rod, rust-proofing oil is placed in the rust proofing sleeve and can soak the piston rod, and effective protecting effect is achieved, so that the piston rod is prevented from rusting and corroding completely, normal operation of the cylinder can be guaranteed effectively, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic devices, in particular to an anti-rust hydraulic oil cylinder. Background technique [0002] As a commonly used mechanical component, hydraulic cylinders have been widely used in the mechanical field. Existing hydraulic cylinders are equipped with dust-proof rings to block external dust, but during the long-term reciprocating motion of the piston rod, not only the piston rod Exposed to the outside, it is easy to be damaged, and it will rust when exposed to water, which will affect the performance and shorten the service life. Contents of the invention [0003] In order to overcome the disadvantages of the existing hydraulic oil cylinders that are easily damaged and rusted when exposed to water, the invention provides a rust-proof hydraulic oil cylinder. [0004] The technical solution adopted by the present invention to solve the technical problems is: a rust-proof hydraulic oil cylinder, inc...
