[0033] When the extrusion shaft 4 slides along the inside of the sliding groove 3, the moving block 5 will be moved, and due to the limiting of the limiting block 7 to the sliding block 6, at this time the moving block 5 will simultaneously drive the two sliding blocks 6 to move upward along the inside of the limiting block 7, and at the same time the rack 8 will be driven upward by the moving block 5, and due to the meshing connection between the rack 8 and the gear 9, at this time the rack 8 will drive the circular shaft 10 to rotate around the shaft joint of the sleeve of the outer shell 1 through the gear 9, and at this time the circular shaft 10 will drive the arc-shaped toothed plate 15 to rotate through the eccentric wheel 11, and then the arc-shaped toothed plate 15 will extrude the safety rope 2 in rotation, so as to achieve the effect of automatically locking the outer shell 1 when falling occurs. Due to the design of the arc-shaped toothed plate 15, the friction between the eccentric wheel 11 and the safety rope 2 can be enhanced.

[0034] The right side of the outer shell 1 is fixedly provided with a second hinge block 13, the inside of the second hinge block 13 is hingedly provided with a first hinge block 12, and the outer surface of the first hinge block 12 is fixedly provided with a rotating block 28.

[0041] When the vertical rod 17 moves upward, the first spring 19 will be compressed, and due to the elastic force of the first spring 19, the extrusion shaft 4 as a whole will have good reset effect, so that the operator can be rescued after the falling protector can automatically release the locking of the safety rope 2.

[0042] The outer surface of the shell 1 is movably sleeved with a vertical shaft 20, and the outer surface of the vertical shaft 20 is fixedly provided with a baffle 21.

[0043] Due to the movably sleeving of the vertical shaft 20 and the shell 1, the vertical shaft 20 can drive the baffle 21 to rotate around the sleeving position of the shell 1, and when the baffle 21 rotates, the inside of the shell 1 is in an open state, so that the operator can place the safety rope 2 in the inside of the shell 1.

[0044] The outer surface of the baffle 21 is movably connected with a stop block 22, the outer surface of the stop block 22 is fixedly connected with the inside of the shell 1, and the inside of the stop block 22 is attached to the outer surface of the vertical shaft 20.

[0045] Due to the design of the stop block 22, the rotation stroke of the baffle 21 can be limited, and the baffle 21 can be well positioned, and when the baffle 21 contacts the stop block 22, the inside of the shell 1 is in a closed state.

[0046] The top end of the shell 1 is fixedly provided with an arc block 23, the inside of the arc block 23 is movably sleeved with a circular plate 24, the right side of the circular plate 24 is fixedly provided with a movement shaft 25, and the outer surface of the movement shaft 25 is movably sleeved with the inside of the vertical shaft 20.

[0047] Due to the movably sleeving of the circular plate 24 and the inside of the arc block 23, the circular plate 24 can drive the movement shaft 25 to move left and right along the inside of the arc block 23, and when the movement shaft 25 is sleeved in the inside of the vertical shaft 20, the vertical shaft 20 can be locked as a whole, and when the movement shaft 25 moves to the left, the locking of the vertical shaft 20 is released, so that the vertical shaft 20 can drive the baffle 21 to rotate.

[0048] The left side of the circular plate 24 is fixedly provided with a second spring 26, and the left end of the second spring 26 is fixedly connected with the inside of the arc block 23.

[0049] When the circular plate 24 moves to the left, the second spring 26 is compressed, and due to the elastic force of the second spring 26, the movement of the circular plate 24 as a whole is well reset.

[0050] The top end of the circular plate 24 is fixedly provided with a pull block 27, and the outer surface of the pull block 27 is slidably connected with the inside of the top end of the arc block 23.

[0051] Due to the design of the pull block 27, the operator can drive the circular plate 24 to move by pulling the pull block 27.

[0052] The working principle and use process of the utility model:

[0053] When the operator needs to put the safety rope 2 into the shell 1, first the operator pulls the pull block 27, which will drive the circular plate 24 to move left along the inside of the arc block 23, at this time the circular plate 24 will compress the second spring 26, at the same time the movement shaft 25 will move left under the drive of the circular plate 24, then the movement shaft 25 will be released from the sleeve connection with the inside of the vertical shaft 20 in the left movement, at this time the operator pulls the baffle 21, which will drive the vertical shaft 20 to rotate around the sleeve connection with the shell 1 as the axis, at this time the inside of the shell 1 will be opened in the rotation of the baffle 21, then the operator will put the safety rope 2 into the inside of the shell 1, then the operator will rotate the baffle 21 in the opposite direction to reset, when the baffle 21 contacts the block 22, it will be blocked by the block 22, at this time the baffle 21 will stop rotating, due to the design of the block 22, it will be able to position the rotation of the baffle 21, then the operator releases the pull block 27, due to the elastic force of the second spring 26, at this time the second spring 26 will drive the movement shaft 25 to move right through the circular plate 24 to reset, then the movement shaft 25 will move to the inside of the vertical shaft 20 to lock the rotation of the whole vertical shaft 20, so as to achieve the function that the fall protector can be conveniently assembled with the shell 1.

[0054] When the operator falls when climbing the electric tower, at this time the shell 1 as a whole will be offset under the action of inertia, at this time the safety rope 2 will extrude and push the rotating block 28, so that the rotating block 28 rotates around the hinge between the first hinge block 12 and the second hinge block 13 as the axis, at this time the rotating rod 14 will be rotated under the driving of the rotating block 28, and at the same time the extrusion shaft 4 will slide along the inside of the sliding groove 3 under the driving of the rotating rod 14, at this time the outer surface of the extrusion shaft 4 will extrude and push the inside of the moving block 5 in the sliding process, so that the moving block 5 drives the two sliding blocks 6 to move along the inside of the two limiting blocks 7, due to the design of the two limiting blocks 7, the movement of the two sliding blocks 6 will be limited, so that the two sliding blocks 6 can only move up and down, at this time the moving block 5 will drive the two sliding blocks 6 to move upwards along the inside of the two limiting blocks 7, at the same time the rack 8 will be driven upwards by the moving block 5, since the outer surface of the rack 8 is in meshing connection with the outer surface of the gear 9, when the rack 8 moves upwards, it will drive the gear 9 to rotate, at this time the gear 9 will drive the circular shaft 10 to rotate around the sleeve joint with the shell 1 as the axis, and at this time the circular shaft 10 will drive the arc-shaped toothed plate 15 to rotate through the eccentric wheel 11, due to the design of the eccentric wheel 11, when the eccentric wheel 11 drives the arc-shaped toothed plate 15 to rotate, it will extrude and push the safety rope 2, so that the shell 1 as a whole is locked on the safety rope 2, thereby achieving the function of automatically locking the shell 1 when falling, due to the design of the arc-shaped toothed plate 15, it can enhance the friction force when the eccentric wheel 11 contacts with the safety rope 2, and when the extrusion shaft 4 moves upwards, it will simultaneously extrude and push the inside of the movable block 16, at this time the movable block 16 will compress the first spring 19 through the vertical rod 17, due to the design of the first spring 19, it can have a good reset effect on the movement of the extrusion shaft 4 as a whole, so when the operator finds the fulcrum after falling, the anti-falling device will automatically unlock.
