[0026] The present invention provides a lightweight full-body safety belt 100 .

[0027] See also Figure 1 In one embodiment of the present invention, the lightweight full-body safety belt 100 includes a main rope group, a surrounding pole rope 9 and a safety rope 8. The main rope group includes a waist belt 1, a waist belt 2, a shoulder strap 3 and a leg strap 4. The waist belt 1, the shoulder strap 3, the waist belt 2 and the leg strap 4 are made into an integral shape. The shoulder strap 3 is provided with a chest buckle 5, and the chest buckle 5 interweaves the shoulder straps 3 on both sides together. The waist belt 2 and the shoulder strap 3 are both provided with a connecting buckle 7, and the connecting buckle 7 is connected to the surrounding pole rope 9 and the safety rope 8 respectively.

[0028] In this embodiment, the safety rope 8 is made of nylon, vinylon or silk, the outer surface of the fence rope 9 is provided with a protective cover 12, the protective cover 12 is made of leather, vinylon or rubber, the waist belt 1 must be a whole piece, and the waist contact part uses soft material, which is required to be breathable, so the waist belt 1 is a 3D breathable mesh to increase the ventilation and heat dissipation effect and reduce the stuffy feeling.

[0029] It should be noted that the waist support belt 1, the shoulder strap 3, the waist belt 2 and the leg strap 4 are made of high-strength fiber woven fabric to reduce the gram weight.

[0030] In one embodiment of the invention, the waist belt 2 is provided with a waist D-ring 6 for adjusting the tightness of the waist; the safety rope 8 and the fence rope 9 are both provided with connecting hooks 10, and the fence rope 9 and the safety rope 8 are reliably hooked and locked with the connecting buckle 7 on the waist belt 2 or the shoulder strap 3 through the connecting hooks 10.

[0031] In the present embodiment, the waist D-ring 6, the connecting hook 10, the connecting buckle 7 and other hardware are all subjected to ionization anodizing treatment, and the electrical insulation layer formed on the surface can improve the anti-corrosion ability, is environmentally friendly and pollution-free, durable, has good ductility, moisture resistance, mildew resistance, wear resistance and aging resistance, is safe and reliable, easy to wear, and has a service life of more than 5 years; the waist D-ring 6, the connecting hook 10 and the hardware 7 are made of aluminum-magnesium alloy. The density of steel is three times that of aluminum. The use of aluminum-magnesium alloy reduces the weight of the hardware, making the safety belt lighter as a whole, and the surface of the metal accessories is smooth, without pitting and cracks, and is rust-proof, welding is not allowed, and the locking elasticity is good.

[0032] In one embodiment of the present invention, the safety rope 8 is connected to a buffer bag 11, and the buffer bag 11 is connected to the waist belt 2 through the safety rope 8. The buffer bag 11 can prevent the descent from being too fast and share part of the force during the descent.

[0033] In this embodiment, the safety rope 8 has a diameter of 12 mm. Compared with the existing safety rope with a diameter of 16 mm, the rope uses stronger fibers and can withstand the same pressure.

[0034] In one embodiment of the present invention, reflective strips 13 are provided on the shoulder strap 3, the waist belt 2 and the leg strap 4. The reflective strips 13 are directly woven into the webbing, so that the shoulder strap 3, the waist belt 2 and the leg strap 4 have permanent reflective function, which is easy to identify in dim light and is beneficial for monitoring.

[0035] The accessories used in the safety belts mentioned above meet the test standards for safety equipment for working at heights, among which the breaking load verification is as follows: 1. The breaking load of the tether is ≥15kN. 2. The breaking load of the safety hook is ≥12kN. 3. The breaking load of the buffer bag is ≥15kN, the impact force of falling is limited to within 6kN, and the buffer bag should not open when subjected to a tensile force of less than 2kN; 4. Waist belt: static tension 1470N load time 5min. 5. Pole rope: static tension 2206N load time 5min. 6. Safety rope: static tension 2206N load time 5min.

[0036] Compared with the existing safety belts, the present application is lighter, and the total weight of the new finished product is 2780g, which is 1166g lighter, a weight reduction of 29.55%.

[0037] More breathable, the waist belt 1 uses 3D breathable mesh to increase the ventilation and heat dissipation effect and reduce the stuffy feeling. With reflective effect, the leg belt 4, the waist belt 2 and the shoulder strap 3 have multiple reflective functions, using 3M reflective film, waterproof and sun-proof, long-lasting and not falling off, easy to identify in dim light, and conducive to monitoring.

[0038] More flexible and easy to wear, the retractable webbing safety rope is 1.5 meters in free hanging state and has a maximum stretching length of 2 meters, which meets the requirements (the national standard does not exceed 2 meters), shortens the sagging length, and avoids the rope from hooking, pulling and tripping when shifting.

[0039] More durable, all hardware parts are treated with ionized anodizing. The electrical insulation layer formed on the surface can improve the corrosion resistance. It is environmentally friendly and pollution-free and can be used for more than 5 years.

[0040] The present application is a new type of lightweight safety belt that has the same functions as existing safety belts, but is lighter, more durable, more comfortable, more breathable, less absorbent, easier to clean, more reflective, and has multiple adjustment points and hanging points. The safety belt is suitable for various scenarios to prevent falls and injuries.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
