Description

Technical Field

[0001] This utility model relates to the field of linkage technology, and in particular to an adjustable linkage. Background Technology

[0002] Adjustable linkages are mechanical connectors that can flexibly adjust their length or angle. They are widely used in the automotive, machinery manufacturing, and robotics industries. Their core structure typically includes components such as screws, sleeves, and locking devices. The effective working length can be changed by rotating the adjustment component, or the connection angle can be adjusted by the hinge structure. After adjustment, the parameters can be fixed by the locking mechanism to ensure working stability.

[0003] While existing adjustable linkages are widely used in the field of mechanical transmission, traditional products mostly adopt an integrated rigid structure design. Their length adjustment relies on the overall disassembly and replacement, or requires additional tools for segmented disassembly and reassembly. The operation process is cumbersome and time-consuming. Some simple adjustable models adjust the length by loosening bolts, but the fixation is not secure. When the machine vibrates, the adjusted length will change. These problems make traditional adjustable linkages unsuitable for scenarios that require frequent adjustments and cannot meet the current factory requirements for machine flexibility, precision and safety.

[0004] Therefore, it is necessary to invent an adjustable linkage to solve the above problems. Utility Model Content
