Adjustable Hydraulic Jack Slider Locking Mechanism

The patent transforms the static fixing pin mechanism into a dynamic slider locking structure. The slider can move along the boom to different positions and lock automatically, allowing continuous adjustment of boom length and lifting parameters without complex manual operations. The locking structure engages automatically at predetermined positions, simplifying the adjustment process while maintaining safety.

The slider locking structure incorporates automatic locking and unlocking mechanisms that reduce the need for complex manual operations. The spring-loaded locking pins automatically engage with the boom at predetermined positions when the slider is moved, enabling the system to self-regulate and lock without requiring complex user intervention, thus reducing operational complexity.

The patent relocates the locking mechanism from a horizontal arrangement (at the same elevation as the bracket) to a vertical arrangement along the boom's length. This spatial reconfiguration places the locking pins and sliders in different vertical positions, preventing the boom from contacting the locking mechanism during operation while still enabling effective boom length adjustment.

The locking mechanism is segmented into multiple independent locking pins distributed at different positions along the boom. This segmentation allows the boom to be locked at various predetermined lengths while distributing the mechanical stresses, reducing the risk of damage to any single component and extending the overall service life of the mechanism.

The patent introduces dynamic adjustability to the boom and link rod lengths through slider locking structures. These structures allow the lengths to be changed between predetermined positions while maintaining a relatively simple overall structure. The locking mechanism uses basic mechanical components (sliders, springs, and pins) that preserve structural simplicity while enabling adaptability in lifting height and load capacity.

The patent enables changes in the physical parameters (lengths) of the boom and link rod through the slider locking mechanism. By allowing these parameters to be adjusted between fixed positions, the system achieves versatility in lifting operations without requiring a completely complex reconfigurable structure, maintaining a balance between simplicity and adaptability.
