[0016] 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.

[0017] Please see Figs. 1-2This utility model provides a technical solution: an anti-ant, rodent, and water-blocking airport navigation light cable, comprising an outer shell 1, which is made of existing high-density polyethylene mixed with a small amount of environmentally friendly repellent, or simply made of high-density polyethylene. Inside the outer shell 1 is an inner core 2, which is composed of a stranded wire core coated with water-blocking grease, a semi-conductive conductor shielding layer, a cross-linked polyethylene insulation layer, a semi-conductive insulation shielding layer, and a metal shielding layer, arranged from the inside out. Spacer rings 3 are fixedly connected at equal intervals along the axis to the outer surface of the inner core 2. The spacer rings 3 are made of high-density polyethylene, and the body of the spacer rings 3 has a through hole 4. An air tube 5 is installed inside the through hole 4. The air tube 5 is made of PP material. A rubber ring 6 is movably connected to the outer surface of the air tube 5. The rubber ring 6 is formed by surrounding a rubber material with a semi-circular cross-section to improve the friction performance of the connection. The outer surface of the rubber ring 6 is fixedly connected to the inside of the through hole 4. A diaphragm 7 is fixedly connected to the inside of the air tube 5. The diaphragm 7 is made of the same material as the air tube 5 and can provide a certain amount of storage space to achieve a dot matrix protection function. A fixing layer 8 is filled between the outer surfaces of the spacer rings 3. The fixing layer 8 is made of resin casting. The outer surface of the fixing layer 8 is fixedly connected to the inside of the outer shell 1 and the outer surface of the inner core 2 respectively.

[0018] The through holes 4 are arranged radially and at equal angles along the spacer ring 3. The rubber rings 6 are arranged at equal intervals along the axis of the through holes 4. The air tube 5 is fixed inside the through holes 4 by an interference fit with the rubber rings 6. The interference fit connection facilitates the connection and fixation of the air tube 5 and the spacer ring 3. The diaphragm 7 is arranged at equal intervals inside the air tube 5. The air tube 5 is filled with insecticide. The fixing layer 8 is formed by the solidification of resin mixed with rodenticide powder. The rodenticide powder is mixed with the resin and solidified, and then placed inside the outer shell 1. This avoids the loss of efficacy and the problem of loss of protection due to volatilization. The outer diameter of the fixing layer 8 is larger than the outer diameter of the spacer ring 3, and the extension dimension is 2mm. The outer shell 1 is fixed to the spacer ring 3 by the fixing layer 8, ensuring that when rodents damage the cable, they will definitely come into contact with the rodenticide powder.

[0019] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0020] During operation, the equipment first produces spacer rings 3 of suitable size. Multiple rubber rings 6 are then axially and equidistantly positioned inside the through-holes 4 of the spacer rings 3 using either integral molding or adhesive bonding. Next, insecticide is injected into the air tube 5. Then, the air tube 5 is quantitatively divided by a diaphragm 7 through axial equidistant bonding. Next, the inner core 2 is produced using existing technology. During production, spacer rings 3 are axially and equidistantly positioned outside the inner core 2 using adhesive bonding or hot-melt connection. After the inner core 2 is fully produced, the air tube 5 is sequentially inserted through the through-holes 4 of the multiple spacer rings 3 and fixed to the spacer rings 3 by interference fit with the rubber rings 6. Simultaneously, resin mixed with rodenticide powder is solidified through a mold and coated onto the inner core 2 and the spacer rings 3 to form a fixing layer 8. Finally, an outer shell 1 is wrapped around the inner core 2 and the fixing layer 8 using existing technology.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
