[0002] According to the national standard GB / T 3608-2008, "Classification of Work at Heights," "Any work performed at a height where there is a risk of falling from a height of 2 meters or more (inclusive) is considered work at height." This regulation applies to a wide range of work at heights in the construction industry. When working inside a building, any operation on a shelf over 2 meters high is considered work at height. Workers performing work at heights require the use of a safety line. Both ends of the safety line are connected to safety connectors, and workers are connected to the safety line via connecting rings to ensure their safety while working at height. A single-line temporary horizontal safety line is one type of safety line.

[0003] At present, the existing single-line temporary horizontal safety line is usually a steel wire rope, and the toughness, strength and safety factor of a steel wire rope are relatively low during use, which will bring hidden safety hazards to the workers using it.

[0004] Therefore, those skilled in the art provide a single-line temporary horizontal safety line to solve the problems raised in the above background technology. Utility Model Content

The lower end face of the buffer is fixedly connected to a third connecting ring, and the third connecting ring is provided on the second connecting ring. The upper end face of the buffer is fixedly connected to the second hook.

[0008] Furthermore, a first limiting groove is formed at one end of the first hook away from the connecting plate, and a first locking rod is rotatably connected in the first limiting groove.

[0009] Furthermore, a second limiting groove is formed at one end of the second hook away from the buffer, and a second locking rod is rotatably connected in the second limiting groove.

[0019] See also Figures 1 to 3 In the embodiment of the present invention, a single-line temporary horizontal safety line includes a wire rope body 1. The wire rope body 1 has a multi-layer structure. The wire rope body 1 includes a rope core 101, an intermediate rope 102, and an outer rope 103. The rope core 101 is located at the innermost side. There are multiple intermediate ropes 102. The multiple intermediate ropes 102 are arranged in a circular shape on the outer wall of the rope core 101. The outer rope 103 is spirally wound around the outer wall of the multiple intermediate ropes 102. One end of the wire rope body 1 is fixedly connected to the first connector 2. The other end of the wire rope body 1 A second connector 3 is provided at one end, and the upper ends of the outer walls of the first connector 2 and the second connector 3 are fixedly connected with a first connecting ring 4, and the first connecting ring 4 is sleeved with a second connecting ring 5, and a connecting plate 6 is sleeved on one second connecting ring 5, and the upper end face of the connecting plate 6 is fixedly connected with a first hook 7, and a buffer 8 is provided above the other second connecting ring 5, and the lower end face of the buffer 8 is fixedly connected with a third connecting ring 9, and the third connecting ring 9 is sleeved on the second connecting ring 5, and the upper end face of the buffer 8 is fixedly connected with a second hook 10. When using the device, first hang the first hook 7 and the second hook 10 on the hanging part, and then hang the staff on the wire rope body 1. When the staff hanging on the wire rope body 1 suddenly falls, the buffer 8 will use its own elastic characteristics to cushion the downward force of the staff pulling the wire rope body 1 downward. The multi-layer structure of the wire rope body 1 not only improves the toughness and strength of the wire rope body 1, but also makes the safety factor of the wire rope body 1 higher, thereby effectively improving the safety of workers working at heights. The setting of the buffer 8 serves to cushion the sudden fall of workers hanging on the wire rope body 1, thereby making the workers more stable when using the wire rope body 1.

[0020] The first hook 7 has a first retaining groove at its end away from the connecting plate 6, into which a first locking rod 80 is rotatably connected. The second hook 10 has a second retaining groove at its end away from the buffer 8, into which a second locking rod 120 is rotatably connected. The provision of the first locking rod 80 and the second locking rod 120 further stabilizes the connection between the first and second hooks 7 and 10 and the hooking member.

[0021] The upper end surface of the second connector 3 is provided with two through holes in sequence, and one end of the wire rope body 1 passes through the two through holes in sequence. A fixing frame 12 is fixedly connected to one side wall of the second connector 3, and the cross section of the fixing frame 12 is in the shape of a U. A tightener 13 is provided in the fixing frame 12, and one end of the wire rope body 1 that passes through the two through holes in sequence is wound around the outer wall surface of the tightener 13. If it is necessary to adjust the length of the wire rope body 1, the tightener 13 is activated, and the activation of the tightener 13 tightens the wire rope body 1. A hanging ring 14 is hung on the outer wall surface of the wire rope body 1. The hanging ring 14 is an open ring, and a closed-loop rod 15 is rotatably connected to the opening of the hanging ring 14. The setting of the hanging ring 14 is convenient for connection with the installation ring on the staff, thereby improving the safety of the staff.

[0022] The working principle of this utility model is:

[0023] When using the device, first hang the first hook 7 and the second hook 10 on the hanging piece, and then the worker hangs on the wire rope body 1. When the worker hanging on the wire rope body 1 suddenly falls, the buffer 8 will use its own elastic characteristics to buffer the downward force of the worker pulling the wire rope body 1 downward.

[0024] 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.
