A hexagonal bolt is provided in the threaded groove, and the rotating block and the ring body are connected by the hexagonal bolt and the threaded groove.
[0012] By adopting the above technical solution, the rotating block can be easily fixed in the vertical slot by connecting the hexagonal bolt through the through slot and the threaded slot.
[0013] Specifically, a first limiting hole is provided through the end of the hexagonal bolt.
[0014] Specifically, the ring body has a rounded chamfer at its edge.
[0015] The beneficial effects of this utility model are:
[0016] (1) The high-altitude fall protection device described in this utility model suspends the U-shaped rod on the external suspended object, and uses pins and cotter pins to facilitate the limiting of the lower end of the flange nut, and uses T-shaped blocks to facilitate the limiting of the upper end of the flange nut, so that the protection device has a high-strength limiting structure.

A rotating shaft 16 is provided on the inner side of the bottom end of the vertical slot 17 through a rotating groove, and the rotating block 8 is connected to the outer side of the rotating shaft 16.
[0025] Both ends of the top of the rotating block 8 are provided with internally threaded sleeve blocks 3. A U-shaped rod 4 is fitted inside the internally threaded sleeve block 3. An external thread 14 is provided on the periphery of the U-shaped rod 4. A T-shaped block 5 is connected to the outer side of the bottom end of the internally threaded sleeve block 3. The top end of the T-shaped block 5 is welded to the inner top of the ring body 1. A flange nut 6 is fitted on the periphery of the U-shaped rod 4 near the external thread 14. The flange nut 6 is located at the lower end of the T-shaped block 5. A second limiting hole 15 is opened through one side of the bottom end of the U-shaped rod 4. A pin 7 is provided in the second limiting hole 15. The pin 7 is located at the lower end of the flange nut 6. A third limiting hole 20 is opened through one side of the bottom end of the U-shaped rod 4. A pin 7 is fitted inside the third limiting hole 20.
[0026] In use, the U-shaped rod 4 is fixed by engaging the flange nut 6 with the external thread 14. Then, the pin 7 is inserted into the third limiting hole 20. The pin 7 and the cotter pin are used to limit the lower end of the flange nut 6, and the T-block 5 is used to limit the upper end of the flange nut 6. This gives the protective device a high-strength limiting structure. When the device is suspended on an external object, it has a high-strength limiting structure and better reliability in use.
[0027] For example, such as Figure 1-3As shown, the present invention also includes a U-shaped plate 11 provided near the inner bottom end of the ring body 1, and a through-strip groove 12 is provided on the top of the U-shaped plate 11.
[0028] When in use, the external safety belt can be easily passed through the slot 12.
[0029] For example, such as Figure 1-3 As shown, the present invention also includes a guide block 13 provided on the inner wall of the threaded slot 12 near the top.
[0030] When in use, the guide block 13 facilitates the insertion of the seat belt into the belt slot 12 and provides a certain guiding effect on the seat belt.

A hexagonal bolt 9 is provided in the threaded groove 19, and the rotating block 8 and the ring body 1 are connected by the hexagonal bolt 9 and the threaded groove 19.
[0032] In use, the rotating block 8 is easily fixed in the vertical slot 17 by passing the hexagonal bolt 9 through the through slot 18 and connecting it to the threaded slot 19.
[0033] For example, such as Figure 1 As shown, the present invention also includes a first limiting hole 10 through which the end of the hexagonal bolt 9 is formed.
[0034] When in use, the external cotter pin is inserted into the first limiting hole 10 to facilitate the limiting of the position of the hexagonal bolt 9.
[0035] For example, such as Figure 1 As shown, the present invention also includes a circular chamfer at the edge of the ring body 1.
[0036] When in use, the rounded chamfers can prevent the edges of the ring from scratching your hands.
[0037] In use, the U-shaped rod 4 is suspended from an external suspended object, such as a railing. After suspension, the bottom end of the U-shaped rod 4 is inserted into the internal threaded sleeve 3, so that the bottom end of the U-shaped rod 4 extends out from the bottom of the internal threaded sleeve 3. The flange nut 6 is then inserted from the outside of the bottom end of the U-shaped rod 4. The flange nut 6 is fixed by engaging with the external thread 14. Then, a pin 7 is inserted into the third limiting hole 20. The pin 7 and the cotter pin are used to limit the lower end of the flange nut 6. The T-shaped block 5 is used to limit the upper end of the flange nut 6. This gives the protective device a high-strength limiting structure. The slot 12 allows the external safety belt to pass through, and the external safety belt is then connected to the safety buckle worn by the personnel. This device provides fall protection for communication construction personnel. The device has a high-strength limiting structure when suspended from an external suspended object, resulting in better reliability during use.
