Description

Technical Field

[0001] The utility model relates to the field of stage equipment, in particular to a suspension rod suitable for stages of different specifications. Background Art

[0002] Stage booms are used to hang lighting fixtures and curtains in theaters, auditoriums, clubs, studios, multi-purpose halls, and gymnasiums. They are used to hang curtains, soft scenery, lighting fixtures, and other equipment. However, traditional booms cannot guarantee the precise hanging of curtains, soft scenery, lighting fixtures, and other equipment.

[0003] The utility model patent with patent number "202122336733.0" and patent name "A Multifunctional Stage Hoist" discloses a hoist body and a lifting mechanism for driving the hoist body to rise and fall; the hoist body includes a main rod with a hollow interior, and both ends of the main rod are sleeved with movable telescopic rods; the main rod is provided with first vertical holes arranged at equal distances along its axial direction, and the telescopic rod is provided with second vertical holes arranged at equal distances along its axial direction. By adjusting the position of the telescopic rod on the main rod, the overall length of the hoist body can be adjusted, thereby adapting to stages of different sizes to a certain extent.

[0004] The inventor believes that with this design, although the boom can be extended and retracted, the lifting mechanism on the top cannot be extended and retracted, which will cause the wire rope to shift. The long-term uneven stress points will create safety hazards. Moreover, the support effect of the single-structure boom itself is average and not safe and reliable enough. Utility Model Content
