Description

Technical Field

[0001] This utility model relates to the field of sheathing tubes, specifically a high-strength tensile sheathing tube. Background Technology

[0002] Sheathing tubing is a type of protective tubing widely used in machinery, electronic equipment, and industrial pipelines. It is mainly used to protect cables, wires, and pipes from physical damage and chemical corrosion caused by the external environment, while also providing a certain degree of mechanical support and protection.

[0003] However, existing sheathing systems have the following drawbacks in practical use: Most existing sheathing systems are single-layered, lacking effective mechanical support design. Under tensile force, especially long-term or repeated tensile stress, the sheathing system is prone to deformation, cracking, or even breakage. For example, in some cable applications requiring frequent movement, the sheathing system quickly loses its protective function under tensile force, leading to damage to the internal cables and affecting the normal operation of the equipment. Existing sheathing systems are also prone to deformation or flattening under external pressure due to insufficient structural strength. This not only affects the normal operation of the cables or pipes inside the sheathing system but may also reduce the gap between the sheathing system and the protected object, increasing the risk of friction and wear. Especially in applications requiring high mechanical pressure, such as underground pipeline laying or confined spaces inside industrial equipment, the insufficient compressive strength of the sheathing system will significantly shorten its service life. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a high-strength tensile sheath tube, which can effectively solve the technical problem of poor tensile and compressive strength of existing sheath tubes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-strength tensile sheath tube, including a tube body, a reinforcing tube sleeved on the surface of the tube body, the reinforcing tube extending along the length direction of the tube body, a plurality of support plates provided on the surface of the reinforcing tube, the support plates extending along the length direction of the reinforcing plates, a braided tube provided outside the reinforcing tube, one end of the support plate being connected to the braided tube, a receiving cavity being formed between the braided tube, the reinforcing tube and the support plate, a plurality of tensile strips provided in the receiving cavity, the tensile strips extending along the length direction of the reinforcing plates, and the tensile strips being distributed in a circular pattern around the receiving cavity.

[0006] Furthermore, the surface of the braided tube is covered with an outer protective layer, and the interior of the outer protective layer forms several elastic cavities. The interior of the elastic cavities is filled with a tough filler, which is composed of rubber filler particles or glass fiber particles.

[0007] Furthermore, the braided tube comprises, from the outside to the inside, a stainless steel wire layer, an outer flexible tube, and a soft fiber layer, wherein the thickness of the stainless steel wire layer is greater than the sum of the thicknesses of the outer flexible tube and the soft fiber layer.

[0008] Furthermore, the outer flexible tube is made of PVC material, the soft fiber layer is made of polyester fiber filaments, and the soft fiber filaments are cross-woven to form a mesh structure.

[0009] Furthermore, the stainless steel wire layer has a two-up-two-down cross braid structure, a one-up-one-down cross braid structure, or a three-up-three-down cross braid structure.

[0010] Furthermore, the tube body is made of silicone material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a high-strength tensile sheath tube. By setting a reinforcing tube on the surface of the tube body and a support plate on the surface of the reinforcing tube, combined with the tensile strip set in the receiving cavity, this multi-layer structure design significantly enhances the tensile and compressive strength of the sheath tube. The reinforcing tube and the support plate greatly improve the mechanical strength of the sheath tube, the braided tube further improves the tensile performance of the sheath tube, and the circumferential distribution of the tensile strip further improves the tensile strength of the tube body in all directions, ensuring that the sheath tube can adapt to various complex environments.

[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] The following is a detailed description of a high-strength tensile sheath according to this utility model:

[0023] Example 1: As Figures 1-5 As shown: A high-strength tensile sheath tube includes a tube body 1, a reinforcing tube 2 sleeved on the surface of the tube body 1, the reinforcing tube 2 extending along the length direction of the tube body 1, a plurality of support plates 3 disposed on the surface of the reinforcing tube 2, the support plates 3 extending along the length direction of the reinforcing plates, a braided tube 5 disposed outside the reinforcing tube 2, one end of the support plate 3 being connected to the braided tube 5, the braided tube 5, the reinforcing tube 2 and the support plate 3 forming a receiving cavity 11, the receiving cavity 11 being provided with a plurality of tensile strips 4, the tensile strips 4 extending along the length direction of the reinforcing plates, the tensile strips 4 being distributed in a circular pattern around the receiving cavity 11.

[0024] The surface of the braided tube 5 is wrapped with an outer protective layer 6. The outer protective layer 6 has a plurality of elastic cavities 7 inside. The elastic cavities 7 are filled with tough filler, which is made of rubber-filled particles. By filling the elastic cavities 7 with tough filler, the buffering performance and wear resistance of the sheath tube are effectively improved. The combination of the elastic cavities 7 and the tough filler can absorb and disperse energy when subjected to external impact, reduce the damage to the inner tube body 1, and extend the service life of the sheath tube.

[0025] The braided tube 5 comprises, from the outside to the inside, a stainless steel wire layer 10, an outer flexible tube 9, and a soft fiber layer 8. The thickness of the stainless steel wire layer 10 is greater than the sum of the thicknesses of the outer flexible tube 9 and the soft fiber layer 8. The outer flexible tube 9 is made of PVC material, and the soft fiber layer 8 is made of polyester fibers. The soft fiber layers are cross-woven to form a mesh structure. The mesh structure of the polyester fibers provides additional mechanical strength and tear resistance, ensuring stable operation of the sheath under various environmental conditions. The stainless steel wire layer 10 has a two-up, two-down cross-woven structure. This two-up, two-down cross-woven structure makes the stainless steel wire layer 10... The density of the 0 is moderate, and its bending ability and strength are both moderate. The braided tube 5 adopts a multi-layer structure of stainless steel wire layer 10, outer hose 9 and soft fiber layer 8. The thickness of stainless steel wire layer 10 is greater than the sum of the thicknesses of outer hose 9 and soft fiber layer 8, so that the sheath tube has high strength while maintaining a certain degree of flexibility and bendability. Stainless steel wire layer 10 provides excellent tensile and compressive strength, while outer hose 9 and soft fiber layer 8 enhance the flexibility of the sheath tube. The tube body 1 is made of silicone material, which has good flexibility and temperature resistance and can maintain stable performance over a wide temperature range.

[0026] This embodiment of a high-strength tensile sheath tube, by setting a reinforcing tube 2 on the surface of the tube body 1, and a support plate 3 on the surface of the reinforcing tube 2, combined with tensile strips 4 set in the receiving cavity 11, this multi-layer structure design significantly enhances the tensile and compressive strength of the sheath tube. The reinforcing tube 2 and the support plate 3 greatly improve the mechanical strength of the sheath tube, the braided tube 5 further improves the tensile performance of the sheath tube, and the circumferential distribution of the tensile strips 4 further improves the tensile strength of the tube body 1 in all directions, ensuring that the sheath tube can adapt to various complex environments.

[0027] Example 2: Figure 6 As shown: The difference between Example 2 and Example 1 is that the stainless steel wire layer 10 has an up-down cross braiding structure, which makes the stainless steel wire layer 10 stronger.

[0028] Example 3: As Figure 7 As shown: The difference between Example 3 and Example 1 is that the stainless steel wire layer 10 has a three-up-three-down cross-weave structure, which makes the stainless steel wire layer 10 more flexible.
