[0012] As a further embodiment of this utility model, the outside of the rotating wheel is provided with an anti-accidental touch frame, and one side of the anti-accidental touch frame is fixedly connected to the lock body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This high-strength polypropylene fiber integrated lock safety belt with a reinforced structure consists of shoulder straps, waist belt, lock body, rotating wheel, anti-accidental activation frame, leg guards, mounting blocks, locking blocks, springs, nylon ropes, and a pivot. First, both legs are passed through the leg guards, then the shoulder straps are hung on the shoulders. The mounting block at the end of the waist belt is inserted into the mounting groove. The mounting block pushes the locking block through its inclined surface, and the locking block compresses the spring. When the locking block aligns with the locking groove of the mounting block, the spring pushes the locking block into the locking groove. The locking block engages with the groove based on the wearer's body size. To unlock the waist belt, the hand is inserted into the anti-accidental activation frame and the rotating wheel is turned. The rotating wheel drives the pivot, and the nylon rope, wrapped around the pivot, pulls the locking block to the outside of the locking groove. At this point, the two mounting blocks can be removed from the mounting groove, allowing the safety belt to be removed. The reinforced waist belt further enhances the safety performance of the safety belt, facilitating both donning and doffing while preventing accidental activation, and is also easily adjustable to suit the user's body size.
