[0045] Reference Figure 1 and Figure 3 The padlock mechanism 2 includes a hanging ring 201, the front end of the hanging ring 201 is rotatably connected to a lock ring 202, the rear end of the inner wall and the front end of the inner wall of the lock ring 202 are fixedly connected to a screw rod 203, the front end screw rod 203 is shorter than the rear end screw rod 203, and the outer wall of the rear end screw rod 203 is provided with a tension spring 204, the front end of the tension spring 204 is fixedly connected to a rotating ring 205, the front end of the rotating ring 205 is rotatably connected to a moving nut 206, and the outer walls of the front end screw rod 203 and the rear end screw rod 203 are both threadedly connected to the inner wall of the moving nut 206;
[0046] Specifically, under normal conditions, the hanging ring 201 is used to connect to an external fixed point or other related components. When a locking operation is required, the locking ring 202 forms a closed ring with the hanging ring 201 by rotating, and the tension spring 204 provided on the rear end screw rod 203 is in a certain compression state, providing forward thrust for the moving nut 206. Since the front end screw rod 203 is shorter than the rear end screw rod 203, the moving nut 206 can move on the front and rear screw rods 203. When the locking ring 202 is rotated and closed, the rotating ring 205 pushes the moving nut 206 to move forward on the screw rod 203. The threaded connection of the moving nut 206 on the front and rear screw rods 203 enables it to achieve a tightening effect during its movement, realizing reliable locking and unlocking functions, and providing stable and safe protection for the connection between the safety belt and the fixed components.

[0048] Specifically, the fastener 12 and the internal bevel teeth 13 can enhance the fastening effect of the left and right adjustment straps 6 and the leg straps 5, prevent the straps from loosening during use, ensure the effective restraint of the safety belt on the body, and improve safety. The reinforcement plate 14 is connected to the front strap 3 and the adjustment strap through a needle and thread sewing process, which enhances the strength and durability of the key connection parts of the safety belt and reduces the risk of rupture due to excessive force. The sponge pad 15 provides a comfortable cushion for the user's shoulders, reduces the pressure of the shoulder strap 1 on the shoulders, and reduces the user's fatigue when wearing it for a long time.
[0049] Reference Figure 1 and Figure 2 The inner top walls of the two shoulder straps 1 are fixedly connected with sponge pads 15, and the two sponge pads 15 are made of highly wear-resistant materials; the two shoulder straps 1 are symmetrically designed, and the outer walls of the two adjustment rings 16 are all rounded; the inner walls of the multiple folding locks 8 are frosted, and the front side of the waist pad 4 adopts a wrinkled anti-slip design;
[0050] Specifically, the smooth design of the outside of the adjustment ring 16 avoids scratching the user's body or equipment during use, and also facilitates the sliding of the adjustment ring 16, so that it can adapt to the user's body shape more flexibly. The frosted inner wall of the folding lock buckle 8 increases the friction between the belt and the belt, making the connection more secure and not easy to slip off. The wrinkled anti-slip design of the waist pad 4 effectively prevents the waist pad 4 from sliding during use, better fits the user's waist, and provides stable support.
[0051] Working principle: When the user wears the safety belt, the two shoulder straps 1 are put on the shoulders. The length of the shoulder straps 1 can be adjusted to a certain extent by crossing the position of the through-holes 10 of the limit fastening plate 9 to adapt to the body shape and comfort requirements of different users. The adjustment ring 16 on the front side can make the front belt 3 slide up and down according to the user's body shape, so that the front belt 3 and the waist pad 4 are in the appropriate position to provide support and protection for the user's waist. The leg straps 5 on the left and right sides of the waist pad 4 are connected to the front belt 3 to form a protective structure around the lower part of the body. In the fixing link, the right adjustment belt 6 connected to the right front belt 3 is connected to the left front belt 3 The left adjustment strap 7 is connected and fastened together with the leg strap 5 through a folding lock buckle 8. The folding lock buckle 8 ensures the firmness of the connection and is also convenient for the user to quickly adjust and lock. Multiple fixed hooks 11 are used to connect external safety ropes or other fixing devices to connect the user to the safe fixed point of the construction site. In actual use, when the user is likely to fall, the shoulder strap 1 bears the main pulling force. By cooperating with the limiting fastening plate 9, the pulling force is evenly distributed to the back, reducing the pressure on a single point. The waist pad 4 and the leg strap 5 prevent the user's body from twisting and swinging excessively during the fall, keeping the body relatively stable.
[0052] In addition, under normal conditions, the hanging ring 201 is used to connect external fixed points or other related components. When a locking operation is required, the locking ring 202 forms a closed ring with the hanging ring 201 by rotating, and the tension spring 204 provided on the rear end screw rod 203 is in a certain compression state, providing forward thrust for the moving nut 206. Since the front end screw rod 203 is shorter than the rear end screw rod 203, the moving nut 206 can move on the front and rear screw rods 203. When the locking ring 202 is rotated and closed, the rotating ring 205 pushes the moving nut 206 to move forward on the screw rod 203. The threaded connection of the moving nut 206 on the front and rear screw rods 203 enables it to achieve a tightening effect during its movement.
