The invention discloses a collision retarding device for stage suspending bars. The collision retarding device for the stage suspending bar comprises a suspending bar, a fixed base, mounting holes, retarding blocks, a steel wire rope, a plugged pin, a lower suspending ring, a suspending rope and a gravity ball, wherein the suspending bar is configured to have a structure that the bottom of the suspending bar is arc and the top of the suspending bar is square; the top of the suspending bar is connected with the fixed base; the width of the top of the suspending bar is less than the width of the fixed base; the retarding blocks are arranged on the two sides of the top of the suspending bar; the plugged pin is arranged on one side, close to the suspending bar, of the corresponding retarding block; the plugged pin is inserted into the suspending bar and is fixed; the length of the plugged pin is more than half of the thickness of the suspending bar; the retarding blocks consist of two right-angled triangles; the outward side of the corresponding retarding block is a bevel edge which is in a right-angled triangle shape; and the retarding blocks and the plugged pin are made of rubber. According to the collision retarding device for the stage suspending bars disclosed by the invention, by using the retarding blocks consisting of two right-angled triangles, huge shaking caused by meeting with obstacles in a moving process of the suspending bar can be avoided, and the rubber material can play a role in damping once the suspending bar meets with the obstacles.
Description
technical field [0001] The invention relates to the technical field of stage suspenders, in particular to a collision mitigation device for stage suspenders. Background technique [0002] The stage boom is a tool for hanging lamps and curtains in theaters, auditoriums, clubs, studios, multi-functional halls and gymnasiums. The stage boom is a horizontal bar used to hang various background cloths or curtains. It runs through the entire stage and can be lifted. It is usually hung above the stage where the audience cannot see it. It is only lowered for fixed hanging when the stage is arranged. things. [0003] However, the existing suspenders are prone to dangerous accidents when they bump into adjacent suspenders during their up and down movement. Therefore, there is a need for a device that can slow down when the suspenders encounter collisions. Contents of the invention [0004] The object of the present invention is to provide a stage suspension rod collision mitigation...
