They are characterized by high strength, high safety, wear resistance, and corrosion resistance, and are widely used in industries such as industry, construction, aerospace, and rescue.

[0003] Existing special slings are mostly made of woven materials, which have good wear resistance and tensile strength, but their cut resistance needs to be improved. Especially in rescue scenarios, the stress points often come into contact with uneven building or equipment edges, so they are prone to wear and tear, making them inconvenient to use.

[0004] To address this, a high-strength special sling with reinforced, cut-resistant edges is proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application uses a shaped silicone tube as the main structural element, with steel wires on the inner side to enhance overall tensile strength, enabling it to withstand greater weight without easily breaking.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution:

[0023] A high-strength special sling with reinforced anti-cut edges includes a shaped silicone tube 1, a steel wire 2 on the inner side of the shaped silicone tube 1, a nylon braided rope 3 spirally wound on the outer side of the steel wire 2, a nylon layer 4 on the outer side of the shaped silicone tube 1, a polyester outer layer 5 on the outer side of the nylon layer 4, a protective section 6 on the outer side of the polyester outer layer 5, and reinforced edging 7 sewn on both the front and back sides of the polyester outer layer 5.

[0024] In this embodiment: a shaped silicone tube 1 is set as the main structure, with steel wire 2 on the inner side to enhance the overall tensile strength, making it able to withstand greater weight without easily breaking. It also effectively blocks rigid cutting when subjected to cutting force, effectively reducing the probability of breakage. Nylon braided rope 3 is spirally wrapped around the outside of the steel wire 2 to further improve the structural stability and tear resistance, while preventing the silicone tube from easily breaking under stress. A nylon layer 4 and a polyester outer layer 5 are sequentially set on the outside of the shaped silicone tube 1. The nylon layer 4 is wear-resistant, reducing external friction damage to the internal structure. The polyester outer layer 5 is chemically resistant and has high strength, forming double protection and extending the service life of the sling. The front and rear sides are sewn with reinforced edging 7 to prevent the outer material from delaminating or tearing.

[0025] Specifically, such as Figure 2 As shown, the inner side of the irregular silicone tube 1 is filled with deformation filler 8, which is made of sponge material.

[0026] Specifically, such as Figure 1 As shown, the top of the protective section 6 is sewn with a hook and loop fastener 9, and the bottom of the protective section 6 is sewn with a hook and loop fastener 10. The hook and loop fastener 9 and the hook and loop fastener 10 are used together.

[0027] Specifically, such as Figure 4 As shown, the protective section 6 is made of rubber material, and a hot melt adhesive sheet 11 is provided on the inner side of the protective section 6. Water is filled between the protective section 6 and the hot melt adhesive sheet 11.

[0028] Specifically, such as Figure 4 As shown, a rigid strip 12 is fixedly connected to the inner side of the protective section 6, and the inner side of the rigid strip 12 is fixedly connected to the outer side of the hot melt adhesive sheet 11.

[0029] In this embodiment: the inner side of the shaped silicone tube 1 is filled with a deformation filler 8 made of sponge material, which can absorb the impact force during load-bearing, buffer and reduce shock, reduce the direct friction between the steel wire 2 and the silicone tube, protect the internal structure, and also make the sling better fit the surface contour of the object being lifted due to the compressibility of the sponge, so that the force is more evenly distributed. By setting the hook and loop sides 9 and hook and loop sides 10 to cooperate, since the protective section 6 is used to be sleeved on the outside of the main sling body, that is, the polyester outer layer 5, if multiple protective sections 6 need to be installed, the front and back sides can be staggered in sequence and fixed to each other by the hook and loop sides 9 and hook and loop sides 10. The protective section 6 can be used when in contact with sharp objects or stress points. Its rubber material also has good friction performance. When working in high temperature environment or open flame environment, the hot melt adhesive sheet 11 melts. At this time, the water filled inside will leak out and wet the polyester outer layer 5 and the internal structure, so as to reduce the probability of the main structure burning or breaking.

[0030] Specifically, such as Figure 1 As shown, a puncture needle 13 is provided on the outer side of the protective section 6. The puncture needle 13 passes through the protective section 6, the reinforcing edging 7, the polyester outer layer 5, the nylon layer 4 and the shaped silicone tube 1 in sequence, and is fitted with an end cap 14.

[0031] Specifically, such as Figure 1 As shown, the portion of the puncture needle 13 extending beyond the cap 14 is bent.

[0032] In this embodiment: By setting a puncture needle 13, the protective segment 6 is fixed relative to the small ghost position of the polyester outer layer 5. When in use, the puncture needle 13 can penetrate the protective segment 6, and after penetrating the protective segment 6, the reinforcing edge 7, the polyester outer layer 5, the nylon layer 4 and the shaped silicone tube 1, it is limited by the end cap 14, and the end cap 14 is bent on the outside to prevent it from falling off.

[0033] Working principle: The main body is a special-shaped silicone tube 1. The inner side is equipped with steel wire 2 to provide high tensile strength and cut resistance. The outer side is spirally wound with nylon braided rope 3 to enhance structural stability and tear resistance. The inner side of the silicone tube is filled with sponge deformation filler 8 to buffer shock and distribute the force evenly. The outer side is successively equipped with nylon layer 4 and polyester outer layer 5 to resist friction and chemical corrosion, forming double protection. The front and back sides of the polyester outer layer 5 are reinforced with stitched edges 7 to prevent delamination and tearing. The protective section 6 is made of rubber, and its inner hot melt adhesive sheet 11 is bonded to the polyester outer layer 5. The interior is filled with water to disperse the impact force. Low temperature freezing enhances rigidity. The inner rigid strip 12 improves bending stiffness. The outer piercing needle 13 penetrates each layer and bends and fixes it to ensure the overall structure is stable, solving the problems of insufficient cut resistance and wear resistance and easy wear of traditional slings.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
