Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder components, in particular to a novel hydraulic cylinder component. Background Art

[0002] The 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 using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] At present, the hydraulic cylinder assemblies on the market are mainly composed of a hydraulic cylinder body, an engineering connection frame and a position adjustment assembly, wherein the hydraulic cylinder body can be connected to the engineering part through the engineering connection frame, and the position adjustment assembly allows the user to fine-tune the height of the engineering connection frame. For example, Chinese patent announcement CN220910133U discloses an engineering hydraulic cylinder assembly. However, since the user can only fine-tune the height of the engineering connection frame but cannot fine-tune the inclination angle of the engineering connection frame, the adaptability of the hydraulic cylinder assembly is often low due to the single fine-tuning direction. At the same time, since the internal space of the engineering connection frame is fixed, the application scope of the hydraulic cylinder assembly is reduced. Utility Model Content
