Description

Technical Field

[0001] The utility model relates to the technical field of busbar box installation, and more specifically to a busbar duct fixing frame. Background Art

[0002] When installing a busbar box through a floor slab, a through-hole must be reserved in the slab, through which the busbar box passes. A mounting bracket is required on the top of the slab to secure the busbar box. Traditional mounting brackets lack shock absorption capabilities, causing the busbar box to shift and deform when subjected to external shock and vibration, potentially damaging or malfunctioning equipment and wiring. Existing shock-absorbing brackets typically use vertical springs to provide some damping for vertical vibrations, but are unable to dampen horizontal vibrations. Consequently, existing shock-absorbing brackets have limited damping effectiveness and provide inadequate protection for the busbar box.

[0003] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content
