Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 3 In the embodiment of the utility model, a high-altitude safety rope buckle device for electric power construction includes a movable seat 1, a guide ring 2 is fixed to one side of the movable seat 1, a guide groove 3 is opened on the inner wall of the movable seat 1, and a transmission mechanism 4 is arranged on the movable seat 1;

[0032] The transmission mechanism 4 includes a limiting unit and a transmission unit;

[0033] The limiting unit is used to limit the rope;

[0034] The transmission unit is used to provide power for the movement of the limit unit;

[0035] The limiting unit includes a pressing rod 402, a positioning rod 403, a spring 404, a limiting block 408, and a stop block 409;

[0036] The pressing rod 402 is axially slidably mounted on the inner wall of the movable seat 1 and extends to the outside of the movable seat 1. The pressing rod 402 is used to limit the broken rope;

[0037] The positioning rod 403 is fixed to the inner wall of the movable seat 1 and is used to provide an axial guide for the pressing rod 402;

[0038] The two ends of the spring 404 are respectively clamped on the inner wall of the movable seat 1 and the outer wall of the pressing rod 402. The spring 404 is used to provide a directional thrust to the pressing rod 402 at all times.

[0039] The limit block 408 is laterally slidably mounted on the inner wall of the movable seat 1 , and the limit block 408 is used to limit the movement of the pressing rod 402 which is subjected to the elastic force of the spring 404 ;

[0040] The stop block 409 is fixed to the outer wall of the limit block 408, and the stop block 409 is used to receive the rotation thrust from the stop rod on the outer wall of the second rotating rod 407;

[0041] The transmission unit includes a rotating wheel 401, a first rotating rod 405, a transmission rod 406, and a second rotating rod 407;

[0042] The rotating wheel 401 is rotatably mounted on the inner wall of the movable base 1 and extends to the outside of the movable base 1. The rotating wheel 401 is used to drive the first rotating rod 405 to rotate synchronously;

[0043] The first rotating rod 405 is fixed to the outer wall of the shaft of the rotating wheel 401 and is rotatably connected to the inner wall of the movable seat 1. The first rotating rod 405 is used to drive one end of the transmission rod 406 to rotate circumferentially;

[0044] The transmission rod 406 is eccentrically connected to the outer wall of the first rotating rod 405, and the transmission rod 406 is used to drive the second rotating rod 407 to rotate synchronously;

[0045] The second rotating rod 407 is rotatably mounted on the inner wall of the movable seat 1 . The second rotating rod 407 is used to drive the supporting rod fixed on the outer wall to rotate synchronously when in a rotating state.

[0046] In this embodiment: when using this device, one end of the rope is passed through the guide ring 2, passed through the guide groove 3 through the guide ring 2, and then passed through a guide groove 3 and passed through a guide ring 2 again, so that the rope is in an "M" shape on the movable seat 1. The rope is between the pressing rod 402 and the movable seat 1, and the pressing rod 402 does not contact the rope, so that the movable seat 1 can move freely. When the rope breaks, the broken rope will produce greater friction with the rotating wheel 401 on the outer wall of the movable seat 1 under high movement, causing the rotating wheel 401 to rotate. The rotating rotating wheel 401 drives the first rotating rod 405 to rotate synchronously, and the rotating first rotating rod 405 drives one end of the transmission rod 406 to rotate synchronously circumferentially, so that The other end of the transmission rod 406 rotates synchronously in the circumferential direction, thereby driving the second rotating rod 407 to rotate. The rotating second rotating rod 407 drives the support rod fixed on the outer wall to rotate synchronously and contact the inclined surface of the support block 409, giving the support block 409 a thrust, so that the support block 409 drives the limit block 408 to move laterally along the inner side of the movable seat 1, so that the limit block 408 no longer rests on the end of the pressing rod 402. At this time, the pressing rod 402 will move axially along the outer wall of the positioning rod 403 under the action of the first rotating rod 405, so that the inclined protrusion on the inner side of the pressing rod 402 contacts the rope, controls the movable rope, and fixes a rope on the movable seat 1 fixed to the worker, further improving safety.

[0047] Please refer to Figure 1-Figure 3 A push rod is fixed to the outer wall of the second rotating rod 407, and the rotation trajectory of the push rod coincides with the position of the push block 409. The inner wall of the movable seat 1 is formed with a space for matching the rotation trajectory of the transmission rod 406 and the push rod on the outer wall of the second rotating rod 407. The outer wall of the push block 409 is in an inclined state, and the inner wall of the movable seat 1 is formed with a sliding groove for the lateral movement of the limit block 408 and the push block 409. The outer wall of the pressing rod 402 is a "U"-shaped structure as a whole, and a plurality of inclined protrusions are formed on the inner side of the pressing rod 402.

[0048] In this embodiment: through this structure, when the rope breaks, the worker can move downward synchronously with the movable seat 1, so that the rope and the movable seat 1 move relative to each other, and the outward setting of the rotating wheel 401 on the movable seat 1 allows the rotating wheel 401 to maintain contact with the rope, receiving a larger friction force, and the limit block 408 that contacts the end of the pressing rod 402 is also subjected to the elastic force from the spring 404, so that the limit block 408 always rests on the end of the pressing rod 402.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
