[0030] Reference Figure 1-3 The metal roof anti-fall connection device is used to connect the metal roof anti-fall wire rope, in order to facilitate the fixation of the anti-fall wire rope on the metal roof and fix it firmly.

[0031] The metal roof anti-fall connection device comprises a fastener 3, a fixing member 5 and a bolt 4;

[0032] The roof panel 1 is fixed to the top of the T-shaped support 101 by a locking machine. The fixing method of the roof panel 1 and the support 101 is the existing technology and will not be repeated. The fastener 3 is hook-shaped. The fastener 3 is also arranged at the top of the support 101 and is located outside the roof panel 1. The hook-shaped fastener 3 can be buckled on the top of the support 101.

[0033] An arc groove 301 is provided on the inner wall of one side of the fastener 3, and a rotating part 501 is provided on the upper end of the fixing member 5. The rotating part 501 is cylindrical and matched with the arc groove 301. The cylindrical rotating part 501 can be inserted into the interior of the arc groove 301 along the axial direction, so that the fixing member 5 is connected to the fastener 3, and the cylindrical rotating part 501 can rotate inside the arc groove 301. A fixing part 502 is provided at the lower end of the fixing member 5. The fixing part 502 is hook-shaped and has a hook opening on one side. The wire rope 2 can be placed inside the hook of the fixing part 502 through the hook opening.

[0034] A through hole is provided on one side of the fastener 3, and the through hole is located below the arc groove 301. The hexagon socket bolt 4 can pass through the through hole. A slot is provided on the inner wall of one side of the fastener 3. The first nut 401 is clamped in the slot. The bolt 4 is threadedly connected with the first nut 401. By rotating the bolt 4, the bolt 4 can be inserted into the through hole of the fastener 3, so that one end of the bolt 4 can be pressed against the middle side wall of the fixing member 5. Since the hook opening of the fixing part 502 faces the roof panel 1, the bolt 4 makes the hook opening fit the roof panel 1 to fix the hook The opening is closed so that the steel wire rope 2 inside the fixing part 502 cannot fall off, and a second nut 402 is provided on the bolt 4, and the first nut 401 and the second nut 402 are respectively located on the inner and outer sides of the fastener 3. After the bolt 4 fixes the fixing part 5 on the roof panel 1, the bolt 4 and the fastener 3 can be fixed by screwing the second nut 402, thereby ensuring that the fastener 3 and the fixing part 5 are fixed to the roof panel 1 through the first nut 401 and the second nut 402 on the bolt 4.

[0035] The working principle of the metal roof anti-fall connection device is as follows: the roof panel 1 is fixed to the top of the support 101 by a locking machine, and then the hook-shaped fastener 3 is buckled on the top of the support 101, that is, the locking outside of the roof panel 1, and then the cylindrical rotating part 501 is axially inserted into the inside of the arc groove 301, so as to connect the fixing part 5 with the fastener 3, and then the wire rope 2 is placed inside the hook of the fixing part 502 through the hook opening, and then the bolt 4 is screwed into the fastener 3, and the bolt 4 passes through the through hole and is threadedly connected with the first nut 401, and the bolt 4 is continuously rotated so that one end of the bolt 4 is against the middle side wall of the fixing part 5. Since the cylindrical rotating part 501 can be in the arc groove 3 01 rotates inside, the fixing part 502 at the bottom will be close to the roof panel 1 and against the side of the roof panel 1. Since the hook opening of the fixing part 502 faces the roof panel 1, the bolt 4 will make the hook opening fit the roof panel 1, thereby closing the hook opening, so that the steel wire rope 2 inside the fixing part 502 cannot fall off, and finally, by twisting the second nut 402, the bolt 4 can be fixed to the fastener 3. Since the first nut 401 and the second nut 402 are respectively located on the inner and outer sides of the fastener 3, the tightening force of the first nut 401 and the second nut 402 can ensure that the fastener 3 and the fixing part 5 are firmly fixed on the locking edge of the roof panel 1, so that the steel wire rope 2 is firmly fixed.
