Description

Technical Field

[0001] This utility model relates to the field of protective sleeve technology, and in particular to a glass fiber protective sleeve. Background Technology

[0002] Fiberglass sheathing typically consists of an inner tube and a coating. The inner tube is woven from fiberglass yarn, and the coating is applied to both the outer surface and inner wall of the inner tube. The outer surface coating has flame-retardant properties, while the inner wall coating has heat resistance, insulation, and chemical stability. Fiberglass sheathing is commonly used in electrical insulation and industrial protection applications. However, existing fiberglass protective sheathings suffer from relatively low structural hardness in both the inner tube and coating, making them prone to puncture and deformation when impacted by sharp objects. This often results in punctures and insufficient protection for cables. While existing fiberglass sheathings improve protection by adding armor, this also increases the thickness of the fiberglass tube, reducing heat dissipation. Utility Model Content

[0003] The problem this invention aims to solve is that while existing fiberglass sleeves improve the protection of the outer surface, they also increase the thickness of the fiberglass tube, which reduces the heat dissipation of the fiberglass protective sleeve.

[0004] To solve the above-mentioned technical problems, this utility model provides a fiberglass protective sleeve, including an inner tube, a waterproof and moisture-proof layer, and an outer tube. The outer surface of the inner tube is provided with a waterproof and moisture-proof layer, and the outer tube is provided on the outer surface of the waterproof and moisture-proof layer. The inner tube is made of fiberglass material, and the outer tube is made of PVC material with a polygonal surface. Multiple heat dissipation holes are equidistantly spaced inside the outer tube.

[0005] Preferably, the inner tube is woven from alkali-free glass fiber yarn.

[0006] Preferably, the waterproof and moisture-proof layer is made of silicone and is pressed onto the outer surface of the inner tube.

[0007] Preferably, the outer tube has a decagonal structure.

[0008] Preferably, the outer surface of the outer tube has a circular arc structure.

[0009] Preferably, the outer surface of the outer tube is provided with multiple anti-slip strips at equal intervals.

[0010] Preferably, the inner wall of the outer tube is provided with multiple fixing strips.

[0011] Preferably, the fixing strip is pressed together with the insulating coating.

[0012] Preferably, the heat dissipation holes are axially oriented towards the inner tube body.

[0013] Preferably, the inner wall of the inner tube is coated with an insulating coating, which is an organosilicon resin coating.

[0014] Compared with the prior art, this utility model provides a fiberglass protective sleeve with the following features:

[0015] Beneficial effects:

[0016] 1. This utility model features an outer tube made of PVC material with a polygonal surface and heat dissipation holes. PVC material has high hardness and mechanical strength, and can withstand the impact and compression of external sharp objects. The polygonal structure of the outer tube provides greater stability when placed compared to a cylindrical structure. Compared to a cylinder, its structure can more effectively resist damage from external forces and has better resistance to deformation. The waterproof and moisture-proof layer is connected to the outer tube through heat dissipation holes, facilitating the transfer of heat from the inner tube to the outside and improving the heat dissipation of the fiberglass sleeve. This solves the problem that while improving the outer surface protection of existing fiberglass sleeves increases the thickness of the fiberglass tube, it reduces the heat dissipation of the fiberglass protective sleeve.

[0021] This utility model relates to a fiberglass protective sleeve, such as Figure 1-3As shown, the cable includes an inner tube 1, a waterproof and moisture-proof layer 2, and an outer tube 3. The outer surface of the inner tube 1 is provided with the waterproof and moisture-proof layer 2, and the outer tube 3 is provided on the outer surface of the waterproof and moisture-proof layer 2. The inner tube 1 is made of fiberglass, and the outer tube 3 is made of PVC with a polygonal surface. Multiple heat dissipation holes 4 are evenly spaced inside the outer tube 3. By setting the inner tube 1, waterproof and moisture-proof layer 2, and outer tube 3 sequentially from the inside out, a fiberglass protective sleeve is formed. The inner tube 1 is the main load-bearing structure, woven from fiberglass weft and warp yarns, providing good mechanical strength and rigidity. The waterproof and moisture-proof layer 2 is used to prevent external moisture from reaching the cable surface. The outer tube 3 is made of PVC... Made of a polygonal material with a polygonal surface, PVC material has high hardness and mechanical strength, and can withstand the impact and compression of external sharp objects. By setting the outer tube body to a polygonal structure, it has stronger stability when placed compared to a cylindrical structure. Compared to a cylinder, its structure can more effectively resist the damage of external forces and has better resistance to deformation. By setting heat dissipation holes 4, the waterproof and moisture-proof layer 2 and the outer tube body 3 are connected through the heat dissipation holes 4, which facilitates the transfer of heat from the inner tube body 1 to the outside, improving the heat dissipation of the fiberglass sleeve. This solves the problem that the existing fiberglass sleeves, while improving the protection of the outer surface, increase the thickness of the fiberglass tube, which reduces the heat dissipation of the fiberglass protective sleeve.

[0022] In this embodiment of the utility model, the inner tube 1 is woven from alkali-free glass fiber yarn. By setting the inner tube 1 to be woven from alkali-free glass fiber yarn, it has good insulation, mechanical strength and high temperature resistance, and can provide basic structural support for the sleeve.

[0023] In this embodiment of the utility model, the waterproof and moisture-proof layer 2 is made of silicone and is pressed onto the outer surface of the inner tube 1. By setting the waterproof and moisture-proof layer 2 to be made of silicone, the good waterproof and moisture-proof properties of silicone are utilized to improve the waterproof and moisture-proof effect.

[0024] In this embodiment of the invention, the outer tube 3 is a decagonal structure. By setting the outer tube 3 to a decagonal structure, compared with a cylinder, its structure can resist the damage of external forces more effectively to a certain extent and has better resistance to deformation.

[0025] In this embodiment of the invention, the outer surface of the outer tube 3 is an arc structure. By setting the outer surface of the outer tube 3 to be an arc structure, it is easier to improve stress dispersion, reduce the risk of structural damage, improve overall stability, and enhance compressive strength.

[0026] In an embodiment of this utility model, multiple anti-slip strips 5 are equidistantly spaced on the outer surface of the outer tube 3. By setting the anti-slip strips 5, the friction force on the outer surface of the outer tube 3 is enhanced, and the stability during placement is improved.

[0027] In an embodiment of this utility model, the inner wall of the outer tube 3 is provided with a plurality of fixing strips 6. By providing fixing strips 6, it is easy for the outer tube 3 to be firmly connected to the insulating coating 7.

[0028] In this embodiment of the invention, the fixing strip 6 and the insulating coating 7 are pressed together. By setting the fixing strip 6 and the insulating coating 7 to be pressed together, the stability of the connection between the fixing strip 6 and the insulating coating 7 is improved.

[0029] In this embodiment of the utility model, the heat dissipation hole 4 is axially arranged towards the inner tube 1. By setting the heat dissipation hole 4 axially towards the inner tube 1, the heat transfer space is reduced, which facilitates the transfer of heat from the inside of the inner tube 1 to the outside.

[0030] In an embodiment of this utility model, the inner wall of the inner tube 1 is coated with an insulating coating 7, which is an organosilicon resin coating. By setting the insulating coating 7, the wires and cables are protected, the conductors of the wires and cables and corrosive liquids are prevented from contacting the fiberglass tube, and the coefficient of friction is reduced, so that the cables can be run through the fiberglass tube.

[0031] In use, first, the cable is inserted into the inner tube 1 and exited from the other end of the inner tube 1. The cable is in contact with the insulation coating 7 inside the inner tube 1. The waterproof and moisture-proof layer 2 is used to block external moisture from reaching the cable surface. The outer tube is made of PVC material with a polygonal surface. PVC material has high hardness and mechanical strength, which improves protection. Through the heat dissipation holes 4, the heat inside the inner tube 1 is transferred from the inside of the inner tube 1 to the outside of the outer tube 3.
