[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] Please see Figures 1-5 This utility model provides a five-point safety belt with adjustable hanging rope length, including a safety belt body and a hanging rope 9 detachably connected to the safety belt body. A hook 7 is fixedly connected to the back junction of the safety belt body. A plurality of hook loops 8 are fixedly connected to the hanging rope 9 along the length direction of the hanging rope 9. The hook 7 and the hook loops 8 are detachably connected to realize the adjustment of the hanging rope length.

[0027] The main body of the seat belt consists of shoulder webbing 1, chest webbing 2, waist webbing 5, leg webbing 6, connecting clips 3, and connecting buckles 4. The chest webbing 2 and waist webbing 5 are both secured together by connecting clips 3 and connecting buckles 4. Specifically, one side of the chest webbing 2 passes through the inner loop of the connecting clip 3 and is folded back for fixation, and has an adjustable length to ensure a closer fit. The other side of the webbing passes through the connecting buckle 4 and is sewn in place via a pre-drilled loop; this side is not adjustable.

[0028] The length of the hanging rope 9 is adjustable. Specifically, a hook loop 8 is set at certain intervals on the rope body of the hanging rope 9, and one end of the hanging rope 9 is connected to the hook 11 through the hook loop 10 to form an adjustable hanging rope 9.

[0029] At the junction of the shoulder webbing 1 and the back, a webbing strip is sewn to secure the hook 7 to the back of the shoulder webbing 1. The hook 7 is connected to the hook loops 8 at different positions on the hanging rope 9 to achieve different lengths of connection with the safety belt body. Finally, the hanging rope 9 is fixed at the hanging point by the hook 11.

[0030] When the five-point safety harness is used for safety protection equipment in high-altitude operations, the hooks 7 and the hook loops 8 at different positions on the rope 9 are connected to form ropes 9 of different lengths. This allows for free adjustment of the length of the rope 9 according to different working conditions and different suspension point heights, preventing the rope from being too long or too short, which would cause inconvenience and safety hazards. At the same time, it can also reduce the overall weight of the equipment, avoid the equipment being too heavy and affecting the operation, and greatly improve the safety of the operation.

[0031] In this embodiment, two hooks 7 can be set at the back junction of the shoulder webbing 1, and two hanging ropes 9 can be used to realize the use of the two hanging ropes 9 with different lengths.

[0032] As a further description of the above embodiment, the hook loop 8 is a long strip of webbing, with both ends of the webbing sewn to the hanging rope 9, and a loop formed in the middle of the webbing that connects to the hook 7.

[0033] Alternatively, the hook loop 8 may be a circular webbing, with one side of the circular webbing sewn to the hanging rope 9.

[0034] In this embodiment, a rectangular sewing edge is formed at the sewing point between the hook loop 8 and the hanging rope 9, and cross-stitching is performed inside the rectangular sewing edge to increase the stability of the connection between the hook loop 8 and the hanging rope 9, thereby improving the safety of the hanging rope 9 during use.

[0035] As a further description of the above embodiment, the hook 7 includes a hook body 701, and the hook body 701 has a first connecting port 702 and a second connecting port 703 arranged in parallel. The first connecting port 702 is used to connect with the webbing at the junction of the shoulder webbing 1 and the webbing to fix the hook 7. The second connecting port 703 is used to connect with the hook loop 8 on the hanging rope 9.

[0036] To facilitate workers in connecting the hook 7 to the hook loops 8 at different positions on the rope 9 according to different work needs, the second connection port 703 is designed as a switchable connection port. Specifically, one end of the second connection port 703 is open, and a fastening element 705 is installed at the opening. The fastening element 705 is connected to the hook body 1 via a spring element 704. When the rope 9 needs to be connected, the fastening element 705 is pulled upwards, allowing the hook loop 8 on the rope 9 to pass through the second connection port 703. At the same time, the spring element 704 springs back and locks, ensuring the stability of the connection between the hook 7 and the rope 9, thereby improving the safety of the safety belt during use. Similarly, when the rope 9 needs to be removed, the fastening element 705 is pulled and the hook loop 8 is removed.

[0037] To further increase the stability of the connection between the hook 7 and the hook loop 8 on the hanging rope 9, and to prevent the fastener 705 from rebounding too much under the elastic force of the spring 704, and to prevent the hook loop 8 from squeezing the fastener 705 under the force during operation, causing the spring 704 to continue to deform in the opposite direction, thereby causing the hook loop 8 to move out of the gap between the fastener 705 and the bottom of the second connection port 703 and causing danger, in this embodiment, a retaining slot 706 is provided at the bottom of the second connection port 703. The retaining slot 706 is provided at the open end of the second connection port 703.

[0038] In summary, in this invention, the safety belt body connects to hook loops at different lengths on the hanging rope via hooks, enabling control over the rope length. This allows workers to choose the appropriate length when the suspension point is at different heights while working at heights, resulting in high operational flexibility and enhanced safety. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses significant industrial application value.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
