AI Technical Summary
Existing friction-damped lifting rods have shortcomings in terms of ease of adjustment and safety. In particular, additional force is required to support the inner cylinder during adjustment, and there is a risk of the inner cylinder accidentally slipping. They cannot achieve arbitrary height suspension and flexible use.
It adopts a sliding sleeve structure between the outer cylinder and the inner cylinder, and the outer wall of the inner cylinder forms a continuous pressing with the elastic blade. Static friction is used to resist the sliding of the inner cylinder. Combined with the design of limit block, buffer and limit lock tongue, it can achieve suspension and safe locking at any height.
It improves operational convenience and safety, allowing the inner cylinder to be suspended at any height, reducing operating noise and the risk of equipment damage, and enhancing reliability.
