[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a new type of one-way lock for a safety rope, including a lower bearing plate 1 and an upper cover plate 2 rotatably installed on the lower bearing plate 1. The outer shapes and sizes of the lower bearing plate 1 and the upper cover plate 2 are the same. A first through hole 21 is opened on the upper cover plate 2. The first through hole 21 is a round hole. A fixed shaft 6 is connected to the lower bearing plate 1. The position of the fixed shaft 6 is coaxially arranged with the position of the fixed shaft 6. A connecting arm 4 is rotatably installed on the outer wall of the fixed shaft 6. A sliding lock 5 is installed on the upper cover plate 2. The sliding lock 5 is used to lock the fixed shaft 6 to prevent the safety rope from loosening.

[0023] The sliding lock 5 includes a mounting plate 51. A second through hole 52 aligned with the first through hole 21 is opened on the mounting plate 51. The second through hole 52 is a strip hole. One end of the second through hole 52 is square, and the other end of the second through hole 52 is arc-shaped. The arc part of the second through hole 52 is coaxially arranged with the first through hole 21. When the upper cover plate 2 is flipped, the top of the fixed shaft 6 will not interfere with the inner walls of the first through hole 21 and the second through hole 52. A clamping plate 53 is slidably installed inside the second through hole 52. The top of the fixed shaft 6 passes through the first through hole 21 and the second through hole 52 to lock with the clamping plate 53.

[0024] A plurality of first cylinders 7 are installed on the lower bearing plate 1, and a plurality of second cylinders 8 are installed on the upper cover plate 2. The first cylinder 7 and the second cylinder 8 are coaxially arranged. A rotating shaft 3 is rotatably installed inside the first cylinder 7 and the second cylinder 8. The rotation of the upper cover plate 2 is realized through the cooperation of the rotating shaft 3, the first cylinder 7 and the second cylinder 8.

[0025] A limiting groove is opened on the inner side wall of the second through hole 52. A spring is connected between the inner wall of the limiting groove and the end of the clamping plate 53 far from the fixed shaft 6. A pushing block 54 is connected to the clamping plate 53.

[0026] Manually move the push block 54 to make the clamping plate 53 move away from the fixed shaft 6 along the limiting groove inside the second through hole 52, canceling the clamping of the fixed shaft 6.

[0027] After the third cylinder 63 in the fixed shaft 6 is installed into the second through hole 52, release the push block 54. Under the elastic force of the spring, the clamping plate 53 is pushed to move towards the third cylinder 63 and is clamped at the bottom of the third cylinder 63.

[0028] Both ends of the connecting arm 4 are respectively provided with a first through hole 41 for fixing the safety rope and a second through hole 42 sleeved on the outer wall of the fixed shaft 6.

[0029] The fixed shaft 6 includes a first cylinder 61 fixed on the lower bearing plate 1, and the first cylinder 61 is inserted and rotatably installed inside the second through hole 42.

[0030] A second cylinder 62 is connected to the first cylinder 61, a third cylinder 63 is connected to the second cylinder 62, and the third cylinder 63 is clamped on the clamping plate 53. The diameter of the second cylinder 62 is smaller than the diameters of the first cylinder 61 and the third cylinder 63.

[0031] During use, manually move the push block 54 to make the clamping plate 53 move away from the fixed shaft 6 along the limiting groove inside the second through hole 52, canceling the clamping of the fixed shaft 6. Then, turn up the upper cover plate 2, pass one end of the safety rope through the first through hole 41 and place it between the rotating shaft 3 and the connecting arm 4. Then, move the push block 54 again, cover the upper cover plate 2, make the third cylinder 63 in the fixed shaft 6 pass through the first through hole 21 and be located inside the second through hole 52. Finally, release the push block 54. Under the elastic force of the spring, the clamping plate 53 is pushed to move towards the third cylinder 63 and is clamped at the bottom of the third cylinder 63, preventing the third cylinder 63 from loosening and ensuring that the safety rope will not fall off.
