Description

Technical Field

[0001] This utility model relates to the field of braided tubing, specifically to a waterproof silicone braided tubing. Background Technology

[0002] Braided tubing is a hollow tubular structure made by cross- or spirally winding fibers, wires, or other flexible materials. It is lightweight, flexible, compressible, and stretchable. Braided tubing is widely used in medical catheters, industrial hoses, aerospace, and sports equipment. Through structural design, it can achieve properties such as pressure resistance, torsion resistance, or dynamic bending resistance, meeting the strength, elasticity, and durability requirements of different applications.

[0003] In existing pipe applications, ordinary pipes have poor sealing at joints, which easily leads to liquid leakage; the outer layer of the pipe lacks effective waterproofing design, allowing water to remain on the surface for extended periods, affecting the waterproofing effect; the overall strength and compressive strength of the pipe are insufficient, making it prone to deformation and damage under external forces; and the resistance to liquid flow inside the pipe is high, resulting in low transport efficiency and affecting the stability of the pipe's performance. Therefore, a new type of pipe that can solve the above problems is needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned defects by providing a waterproof silicone braided tube that prevents liquid leakage, allows water to slide off quickly, is not easily deformed or damaged, and improves liquid transport efficiency. This solves the technical problems of existing technologies, such as easy liquid leakage, reduced waterproofing effect, deformation and damage, and low transport efficiency.

[0005] The objective of this utility model is achieved through the following means:

[0006] A waterproof silicone braided tube includes a braided tube shell, with sealing rings installed at the connecting ends of the braided tube shell. The surface of the braided tube shell is an outer waterproof layer, and an intermediate reinforcing layer is installed on the inner side of the outer waterproof layer. An inner silicone tube is installed on the inner wall of the intermediate reinforcing layer. The surface of the outer waterproof layer is uniformly provided with hydrophobic grooves, and the inner wall of the inner silicone tube is provided with spiral guide grooves.

[0007] Furthermore, the interface of the sealing ring adopts a biomimetic sharkskin structure, and the surface of the sealing ring is uniformly distributed with limiting protrusions. The biomimetic sharkskin structure of the sealing ring interface can effectively reduce fluid resistance and improve sealing stability. At the same time, the limiting protrusions evenly distributed on its surface can enhance the mechanical interlocking with the mating parts, preventing the sealing ring from shifting or falling off under high pressure or vibration conditions, thereby significantly improving the reliability and durability of the braided tube.

[0008] Furthermore, the sealing ring has an internal mounting groove, and shape memory metal springs are evenly installed in the inner cavity of the mounting groove. The mounting groove inside the sealing ring provides a positioning and installation space for the shape memory metal springs. The shape memory metal springs, which are evenly arranged in the inner cavity of the mounting groove, can utilize their shape memory characteristics to automatically restore their initial shape after being deformed by pressure, thereby continuously providing a stable and adjustable elastic compensation force for the sealing ring. This effectively compensates for the gaps caused by wear or temperature changes on the sealing surface, ensuring the long-term reliability of the sealing performance.

[0009] Furthermore, the outer layer of the intermediate reinforcing layer is a strengthening layer, and the inner layer of the intermediate reinforcing layer is a supporting layer. The surface of the strengthening layer is connected to the surface of the supporting layer, which can improve the supporting effect of the intermediate reinforcing layer and also improve the firmness of the intermediate reinforcing layer.

[0010] Furthermore, the inner wall of the reinforcing layer is uniformly covered with stainless steel wires, and the outer surface of the supporting layer is uniformly covered with polyester fibers. The stainless steel wires can significantly improve the tensile strength and compressive strength of the overall structure, effectively resist the internal medium pressure and external mechanical stress, and prevent structural deformation or cracking. The polyester fibers enhance the interlayer bonding force through their high modulus characteristics, while providing flexible support, buffering vibration impact and dispersing stress concentration.

[0011] Furthermore, a buffer pad is installed between the outer waterproof layer and the middle reinforcing layer. The surfaces of the drainage channels are all polished smooth, and there are connecting grooves between the channels. The buffer pad can effectively absorb external impact, and the connecting grooves allow water between the drainage channels to flow and drain out.

[0012] The beneficial effects of this invention are as follows: the added sealing ring effectively enhances the sealing of the connection and prevents liquid leakage; the outer waterproof layer, combined with the evenly distributed hydrophobic grooves on its surface, allows water to slide off quickly, reducing the time water stays on the surface of the outer waterproof layer and improving the waterproof effect; the middle reinforcing layer enhances the overall strength and compression resistance of the braided tube, making it less prone to deformation and damage; the spiral guide grooves on the inner wall of the inner silicone tube guide the liquid to flow in a spiral manner, reducing flow resistance and improving liquid transport efficiency, thereby ensuring the performance stability of the braided tube.

The outer waterproof layer 3, combined with the evenly distributed hydrophobic grooves 6 on its surface, allows water to slide off quickly, reducing the time water stays on the surface of the outer waterproof layer 3 and improving the waterproof effect. The middle reinforcing layer 4 enhances the overall strength and compression resistance of the braided tubing, making it less prone to deformation and damage. The spiral guide grooves 7 opened on the inner wall of the inner silicone tube 5 can guide the liquid to flow in a spiral manner, reducing flow resistance and improving liquid delivery efficiency.
