Detailed Description

The utility model provides a construction safety support rod for building scaffold, including the aluminum alloy telescopic link, rotatory fastener 6 and becket bridle 4, the aluminum alloy telescopic link is including the inner tube 1 and the outer tube 2 that cup joint each other, inner tube 1 begins interval fixed distance apart from the bottom certain distance and sets up marble 3, radial stretching out of inner tube 1 is followed at the both ends of marble 3, the pinhole is seted up to the first marble 3 position in 1 lower part of inner tube, marble card hole 9 has been seted up to outer tube 2 from the top certain distance beginning interval and inner tube 1 the same fixed distance, staple bolt mode fixed becket bridle 4 is passed through at the top of inner tube 1, becket bridle 4 is formed by two staple bolt subassembly bolt butt joint locking, shackle 5 has been seted up at the both ends of staple bolt subassembly, hook 8 on shackle 5 hooks safety belt, the interval sets up rotatory fastener 6 on the aluminum alloy telescopic link, the 1 external.

Marble 3 including marble cap 3.1, interior stay tube 3.2 and spring 3.3, marble cap 3.1 is the open-ended barrel type cap in head calotte root, the fixed joint of interior stay tube 3.2 is on the diameter line of inner tube 1, on 3.2 of stay tube including spring 3.3 cover is established, the both ends of spring 3.3 are connected with marble cap 3.1's root respectively, 1 outer wall of inner tube is stretched out to marble cap 3.1's head.
