Currently, the mainstream seat belts on the market are mostly five-point seat belts. Although the safety of the five-point seat belt is greatly improved compared to the early three-point seat belts, some high-altitude safety accidents in recent years have continued to sound the alarm for us. The social responsibility of safety first and life first has prompted the development of a seat belt with an early warning function.

[0003] The safety belts in the prior art all distribute high-fall stress in a multi-point manner on the belt-shaped safety surface. There is a certain uncertainty in the protection state and effectiveness of the belt-shaped protection for users who are unstable and weightless. As for the protection effectiveness of current safety belts, the safety of safety belts mainly depends on whether the users can use the safety belts correctly and whether they are willing to use them.

[0004] In the field of infrastructure, traditional safety belts have the following problems during use: the safety belts have too many protective belt loops and safety buckles, the structure is complex and inconvenient to wear, and some people do not know how to wear them; the front and rear protective belts of the safety belts are easy to hang on things when the human body is walking, causing instability; the leg protective belt loops of the safety belts are easy to slide down when bending over or squatting, which can easily cause the legs to be squeezed when standing up; when the safety belt falls with a heavy load, the stress is concentrated on the strip-shaped protective belt, which can easily cause concentrated injuries to the human body's linear or point surfaces; traditional safety belts have no active or passive early warning devices.

[0005] Therefore, it is necessary to propose a safety belt with early warning function to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a safety belt with an early warning function to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0025] Embodiment 1, the present invention provides as Figure 1 to Figure 3A safety belt with an early warning function is shown, comprising a high-hanging safety rope 1, an upper protective body 2 and a lower protective body 5. The upper protective body 2 is open-fronted and provided with a zipper. It can also be a long-sleeved or short-sleeved garment with a barrel-shaped structure, which can be adjusted according to specific usage.

[0026] The upper protective body 2 includes a top and an upper vertical safety belt strip 8, which is sewn on the outside of the top. Two upper vertical safety belt strips 8 are provided. The upper protective body 2 also includes an upper horizontal annular safety belt strip 9, which can be provided in multiple numbers. The upper horizontal annular safety belt strip 9 is sewn on the outside of the top and is sewn in an integrated manner with the upper vertical safety belt strip 8.

[0027] The upper horizontal annular safety belt strip 9 is provided with a chest elastic safety belt buckle 3 for controlling the opening or closing of the upper horizontal annular safety belt strip 9 and adjusting the tightness at the same time.

[0028] The upper vertical safety belt strip 8 is in an inverted U shape, and upper safety hooks 4 are provided at both ends of the upper vertical safety belt strip 8 .

[0029] In the specific configuration, the lower protection body 5 includes a lower garment, a lower horizontal annular safety belt strip 11 and a leg annular safety belt strip 14. Two leg annular safety belt strips 14 are provided. The lower horizontal annular safety belt strip 11 is sewn at the top of the lower garment, and the two leg annular safety belt strips 14 are sewn at both sides of the lower garment. The lower vertical safety belt strips 10 are sewn integrally on both the front and rear sides of the leg annular safety belt strip 14, and the lower vertical safety belt strips 10 are sewn on the lower horizontal annular safety belt strip 11.

[0030] The top of the lower vertical safety belt strip 10 is provided with a lower safety ring 7, which cooperates with the corresponding upper safety hook 4. The upper protection body 2 and the lower protection body 5 form a three-dimensional protection structure through the cooperation of the lower safety ring 7 and the corresponding upper safety hook 4.

[0031] In the present invention, the integrated clothing-style design of the safety belt is greatly improved compared with the traditional safety belt, and has strong applicability, is easy to wear, and is highly comfortable, and can also be used as work clothes.

[0032] The lower horizontal annular safety belt strip 11 is provided with a waist-adjusting elastic safety belt buckle 6 for controlling the opening or closing of the lower horizontal annular safety belt strip 11 and adjusting the elasticity at the same time.

[0033] A structural stress-bearing safety ring 13 is sewn on the back of the top, and concentric circle equally divided stitching firm grade circles are arranged between the structural stress-bearing safety ring 13 and the top. A connecting belt is sewn at the outer circle of the structural stress-bearing safety ring 13. Four connecting belts are arranged, and the four connecting belts are distributed in an X shape. The end of the connecting belt away from the structural stress-bearing safety ring 13 is sewn on the corresponding upper vertical safety belt strip 8, and the high-hanging safety rope belt 1 is docked with the structural stress-bearing safety ring 13, and docked at the inner circle of the structural stress-bearing safety ring 13.

[0034] During the sewing process of the structural stress-bearing safety ring 13 and the jacket, concentric equally divided stitching firmness grade circles are set. When a fall from a height occurs, as the human body freely falls and is instantly stressed by the safety rope 1, the structural stress-bearing safety ring 13 can gradually reduce the damage to the human body by stitching failure from the inner circle, playing a buffering and protective role.

[0035] A multi-level buffer zone 15 is formed between the structural stress-bearing safety ring 13 and the two upper vertical safety belt strips 8. The multi-level buffer zone 15 is in a circular ring shape and includes a first stress-bearing buffer zone 1501, a second stress-bearing buffer zone 1502 and a protection and guarantee zone 1503 from the inside to the outside.

[0036] One end of the high-hanging safety rope 1 away from the structural force-bearing safety ring 13 is connected with a high-hanging movable lock buckle 12, and the high-hanging safety rope 1 is suspended on a fixed hanging point through the high-hanging movable lock buckle 12.

[0037] During specific use, encrypted stitches are used at the sewing points, and decorative layers such as reflective tapes can be provided, which can be adjusted according to specific usage conditions.

[0038] When working at height, the operator puts on the upper protective body 2 like a coat and zips up, securely connects and compacts the upper horizontal annular safety belt strip 9 by adjusting the elastic safety belt buckle 3 around the chest, then puts on the lower protective body 5 like wearing pants, and connects and compacts the lower horizontal annular safety belt strip 11 by adjusting the elastic safety belt buckle 6 around the waist, then connects the upper safety hooks 4 to the lower safety rings 7 one by one and locks them in a closed loop, and finally hangs the high-hanging movable lock buckle 12 on a safety rope or a fixed hanging point at a high place.

[0039] When a fall from a height occurs, as the human body freely falls and is instantly stressed by the high-hanging safety rope 1, the structural stress-bearing safety ring 13 can gradually reduce the damage to the human body from the inner circle in a way of suture failure, playing a buffering and protective role; the tension at the high hanging point is transmitted to the structural stress-bearing safety ring 13 through the high-hanging safety rope 1 in the form of a stress point line, and the structural stress-bearing safety ring 13 converts the line tension into a strip surface tension and preferentially transmits it to the upper vertical safety belt strip 8 and the upper horizontal annular safety belt strip 9. The upper vertical safety belt strip 8 is linked to the lower protective body 5 through the upper safety hook 4 and the lower safety ring 7 to achieve strip surface stress. The strip surface stress links the upper protective body 2 and the clothing surface of the lower protective body 5 to be fully stressed, which can disperse and balance the stress points while achieving buffer unloading, thereby ensuring the life safety of the operators.

[0040] Embodiment 2, the present invention provides as Figure 4 A safety belt with an early warning function is shown, and a sound-generating device 16 and a smoke-generating device 17 are provided on the upper protective body 2. The sound-generating device 16 includes a power supply battery 1601, an integrated circuit board 1602, a manual emergency switch 1603, a speaker 1604, and an external passive trigger switch 1605. The power supply battery 1601 cooperates with the integrated circuit board 1602 to supply power to the speaker 1604 and other structures.

[0041] The smoke generating device 17 includes an electronic igniter 1701 , a smoke generating nozzle 1702 , a smoke generating base material 1703 and an electrical connection line 1704 . The electrical connection line 1704 is used to connect the sound generating device 16 and the smoke generating device 17 .

[0042] When the human body loses stability and falls from a high place, the external passive trigger switch 1605 sewn on the multi-level buffer zone 15 on the back side will be stressed when the stitches of the first buffer stress zone 1501 and the second buffer stress zone 1502 break, and the electrical signal will be transmitted to the sound device 16 in the first time. After the electrical signal is processed by the logic of the integrated circuit board 1602, the speaker 1604 and the electronic igniter 1701 are triggered. The electronic igniter 1701 ignites the smoking mother material 1703 in the smoking device 17, and the smoking mother material 1703 generates a large amount of smoke gas, which is ejected from the smoking nozzle 1702, and the smoke is continuously ejected. The electronic igniter 1701 can also be triggered by the manual emergency switch 1603.

[0043] The distress sound emitted by the loudspeaker 1604 is used to warn and guide rescue personnel to provide timely rescue, effectively saving rescue time so that the fallen person can be rescued as soon as possible.
