[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example 1, by Figure 1-2 This utility model relates to a fall-prevention positioning buckle device for high-altitude workers, comprising a housing 1, two hooks 4 on the outer side of the housing 1, an adjustment mechanism 2 on the housing 1, a limiting mechanism 3 between the hooks 4 and the adjustment mechanism 2, and a GPS positioning module inside the housing 1. The positioning module obtains the location information of the buckle in real time by receiving satellite signals or interacting with base stations in the work area, and then sends the location data to the ground monitoring terminal through the built-in wireless transmission unit. Ground personnel can then view the location of the high-altitude workers on the screen in real time. In case of an emergency such as a fall, the positioning module will automatically trigger an alarm and send the precise location for rapid rescue.

A movable ring 303 is movably sleeved on the outer side of the mounting post 304. A spring 302 is fixedly connected between the movable ring 303 and the mounting block 301. The spring 302 is sleeved on the outer side of the mounting post 304. A side groove 308 is provided on the outer side of the movable ring 303. An inner shaft is rotatably connected to the inner side of the side groove 308. 307, a hook 306 is fixedly sleeved on the outer side of the inner shaft 307, a buckle 305 is fixedly connected to the outer side of the hook 4, the hook 306 and the buckle 305 are engaged, a guide post 3010 is fixedly connected to the outer side of the movable ring 303, a guide block 309 is fixedly connected to the outer side of the mounting block 301, the guide post 3010 passes through the guide block 309 and is movably connected to the guide block 309, the movable ring 303 is limited by the guide block 309 and the guide post 3010 to prevent the movable ring 303 from rotating relative to the mounting post 304;
[0028] In use, first slide the movable ring 303 along the mounting post 304 and close to the mounting block 301. At this time, the spring 302 is compressed and drives the hook 306 to move. Then, hang the hook 4 on the object and release the movable ring 303. The hook 306 will engage with the buckle 305 under the elastic force of the spring 302, thus limiting the object and preventing it from coming off.
