AI Technical Summary

Technical Problem

Existing cable supports cannot adaptively adjust to the thermal expansion and contraction of cables due to changes in ambient temperature, which can easily lead to damage to the cable insulation or loosening of the limit, posing safety hazards and making maintenance difficult.

Method used

An anti-vibration and anti-fall mechanism is adopted, which utilizes the movable connection between the inner and outer pressure plates, combined with the meshing transmission of gears and racks, to achieve micro-adaptive adjustment. The damper and spring work together to provide buffering and shock absorption, ensuring the stability of the cable limit and visual adjustment.

Benefits of technology

It achieves stable limiting of the cable during thermal expansion and contraction, avoids limit failure and cable damage, improves the safety and versatility of the device, and reduces maintenance difficulty.

Abstract

This invention discloses an anti-vibration and anti-fall mechanism and a support bracket containing the mechanism, including a base, and further including: an upper clamping seat disposed above the base; an outer pressure plate movably sleeved on the top of the upper clamping seat; and an inner pressure plate movably sleeved on the inner wall of the inner pressure plate. This anti-vibration and anti-fall mechanism and the support bracket containing the mechanism utilize the inner pressure plate's movable connection to the outer pressure plate via a slot, enabling micro-adaptive adjustment. Combined with the meshing transmission of gears and racks, it can precisely control the initial position of the inner pressure plate and achieve free adjustment after the rack disengages, ensuring the fit of the cable limit. When the cable expands or contracts due to changes in ambient temperature, the inner pressure plate can adaptively rise and fall along the slot, simultaneously driving the inner clamping strip and mounting block to move synchronously. This ensures the cable remains in a stable limit state and provides a visual indication of the adjustment status through the floating of the mounting block, preventing limit failure or cable damage due to thermal expansion and contraction.
