[0024] Working principle: When using the safety belt for construction, the worker first takes the harness body 1 and the box body 2 to the desired construction site, and then screws the bolt 25. When the bolt 25 leaves the fixing block 22, the worker pulls the fixing ring 23 to slide on the fixing block 22, and then puts the fixing ring 23 on the fixed object, and then pushes the fixing ring 23 in the reverse direction to reset it, and then screws the bolt 25. The bolt 25 fixes the fixing ring 23 to the fixing block 22 through a threaded connection, which is used to facilitate fixing the box body 2 to the fixed object during construction, so that subsequent workers can The safety protection of the workers when they accidentally fall, and then the workers wear the strap body 1 on their bodies, and then connect the ring 21 and the ring 1 13 together through the D buckle 14, and then the workers can carry out construction. During the construction process, the construction workers pull the safety rope 7 through the construction distance, and the safety rope 7 drives the reel 4 to rotate through the rotation of the pulley 10 and the pulley 2 12, and the reel 4 drives the rotating shaft 3 to rotate on the box 1 2. At the same time, the rotation of the reel 4 twists the first torsion spring 5 and the second torsion spring 6. According to the moving safety rope of the construction At the same time, the pulley 10 and the pulley 2 12 drive the bracket 1 9 and the bracket 2 11 to slide on the slide groove 1 8. When the construction distance is short, the twisting force of the first torsion spring 5 and the second torsion spring 6 causes the drum 4 to roll the safety rope 7, which is used to retract and release the safety rope 7 according to the construction distance of the construction personnel, thereby preventing the safety rope 7 from tripping due to the excessive length of the construction personnel and causing safety accidents. This not only prevents the risk of construction personnel being tripped, but also greatly improves the construction efficiency. When the staff accidentally falls, the safety rope 7 is fully extended. Then one end of the safety rope 7 is fixed on the drum 4, and the drum 4 is fixed on the fixed object through the fixing ring 23 on the box body 2 to prevent the construction workers from falling continuously. When the construction workers fall, they pull the ring 21, and the ring 21 drives the cylinder 20 to slide on the box body 15, and the cylinder 20 drives the slide plate 18 to slide on the slide groove 19, and then the slide plate 18 acts on the four groups of dampers 16 and the spring 17, which effectively alleviates the impact force when the construction workers fall, thereby effectively reducing the damage to the construction workers caused by the fall.
