AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model discloses a kind of damping type lifting support pole and frequency spectrum therapeutic instrument, comprising: outer tube, its inside is equipped with hollow cavity;Inner tube, it is slidably sleeved in the outer tube;Damping block, it is fixed on the inner cavity upper portion of the outer tube, the damping block is equipped with the cavity for the inner tube passes, the inner peripheral wall of the cavity is equipped with multiple inwardly convex and with the continuous pressure joint of the inner tube outer wall Elastic blade;Wherein, the static friction between the elastic blade and the inner tube outer wall, be configured to be able to resist the sliding tendency of the inner tube along its axial in non-active adjustment state. Damping type lifting support pole includes elastic blade installed in outer tube and with inner tube continuous pressure joint. Elastic blade and inner tube sidewall form friction fit, so as to take into account the adjustment convenience and safety of support pole. The support pole can ensure that far-infrared radiation lamp holder keeps stable irradiation position and distance during treatment, and has certain positive effect in medical instrument application field.
