Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with a rod head cleaning structure. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve telescopic motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod head, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application occasion, and other devices are indispensable. The structural forms of hydraulic cylinders are diverse, and there are also many ways to classify them: according to the movement mode, they can be divided into linear reciprocating motion type and rotary swing type; according to the liquid pressure, they can be divided into single-acting type and double-acting type; according to the structural form, they can be divided into piston type, plunger type, multi-stage telescopic sleeve type, gear rack type, etc.

[0003] When the hydraulic cylinder is in use, the piston rod head is extended from the cylinder barrel by the driving force for support. During this process, dust and other impurities are easily adhered to the outer side of the piston rod head. When it is subsequently reset, the piston rod head brings the impurities into the cylinder barrel, which easily affects the normal use of the hydraulic cylinder. In the prior art, a leather ring is generally provided at the junction of the piston rod head and the cylinder barrel, which is fixed to the cylinder barrel and covers the outer side of the piston rod head. The leather ring is cleaned as the piston rod head moves. This leather ring always rubs the rod head regardless of whether the piston rod head is extended or retracted, which increases a certain amount of resistance and wears very quickly, affecting the cleaning effect. It is also inconvenient to replace. Therefore, the utility model proposes a hydraulic cylinder with a rod head cleaning structure to solve the problems existing in the prior art.
