The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0020] The first embodiment of the present application is:
[0021] See also Figure 1-Figure 4 ,in Figure 1 is a side view of the first embodiment of the utility model, Figure 2 This is a front view of the first embodiment of the utility model. Figure 3 The utility model Figure 2 AA line section view, Figure 4 The utility model Figure 3 Enlarged view of the local structure at point B.
[0022] The utility model provides a rat-proof overhead optical fiber introduction, comprising an outer protective layer 101, an inner protective layer 102, a rat-proof layer 103 and a reinforcing core 104, wherein the rat-proof layer 103 comprises a rat-proof ring 105 and a plurality of anti-slip rings 106, the outer protective layer 101 comprises a rubber tube 107 and an anti-corrosion tube 108, the inner protective layer 102 comprises a plurality of optical fiber sleeves 109 and a cable paste 110, and each of the optical fiber sleeves 109 comprises a sleeve body 111 and a plurality of line bodies 112.
[0023] According to this specific embodiment, the reinforcing core 104 is fixedly connected to the inner protective layer 102, the outer protective layer 101 is fixedly connected to the inner protective layer 102, each of the anti-slip rings 106 is fixedly connected to the anti-rat ring 105, the anti-rat ring 105 is fixedly connected to the inner protective layer 102, the rubber hose 107 is fixedly connected to the anti-corrosion pipe 108, each of the optical fiber sleeves 109 is fixedly connected to the anti-rat ring 105, and the cable paste 110 is filled in the anti-rat ring 105 and each of the anti-slip rings 106. Between the optical fiber sleeves 109, each of the wire bodies 112 is fixedly connected to the sleeve body 111, and the multiple anti-slip rings 106 currently provided increase the friction of the anti-rat ring 105 to prevent the anti-rat ring 105 from separating from the inner protective layer 102. The metal anti-rat ring 105 can better protect the inner protective layer 102. The design structure is simple, and solves the problem that when the optical fiber is installed in an outdoor environment, it is easy to be bitten by rodents, resulting in the breakage of the optical fiber, the cost investment is increased, and the user's use is affected.
[0024] Among them, the reinforcing core 104 is located on the inner wall of the inner protective layer 102, the outer protective layer 101 is located on the peripheral side of the inner protective layer 102, each of the anti-slip rings 106 is located on the peripheral side of the anti-rat ring 105, and the anti-rat ring 105 is located on the peripheral side of the inner protective layer 102. The anti-rat ring 105 and multiple anti-slip rings 106 currently set increase the protection thickness for the optical fiber. Since the anti-rat ring 105 is made of metal, mice will not easily bite it, which better protects the use of the optical fiber.
[0025] Secondly, the rubber hose 107 is located on the circumference of the anti-corrosion tube 108, each of the optical fiber sleeves 109 is located on the inner side of the anti-rat ring 105, and each of the wire bodies 112 is located on the inner wall of the sleeve 111. The rubber hose 107, as the outermost protective layer, can isolate most water vapor and impurities. In conjunction with the anti-corrosion tube 108, the corrosion resistance and overall strength of the rubber hose 107 can be increased. The anti-rat ring 105 is a metal hose that can be bent along with the rubber hose 107, which is more adaptable to actual Installation situation: The provision of multiple anti-slip rings 106 increases the friction between the rat-proof ring 105 and the anti-corrosion tube 108, ensuring that the rat-proof ring 105 will not fall off easily, and better protecting each sleeve 111. The cable paste 110 can protect the sleeve 111 and also allow the sleeve 111 to have a sliding property. When a mouse bites through the rat-proof ring 105, it will not continue to bite the sleeve 111 due to the presence of the cable paste 110, thereby not affecting the normal use of the line 112.
[0026] In this embodiment, the multiple anti-slip rings 106 are now provided to increase the friction of the anti-rat ring 105, so as to prevent the anti-rat ring 105 from being separated from the inner protective layer 102. The metal anti-rat ring 105 can better protect the inner protective layer 102. The design structure is simple, and solves the problem that when the optical fiber is installed in an outdoor environment, it is easy to be bitten by rats, resulting in the breakage of the optical fiber, the cost investment is increased, and the use of the user is affected. The anti-rat ring 105 and the multiple anti-slip rings 106 are now provided to increase the protection thickness of the optical fiber. Since the anti-rat ring 105 is made of metal, mice will not easily bite it, so as to better protect the use of the optical fiber. The rubber tube 107, as the outermost protective layer, can isolate most water vapor and impurities. Cooperating with the anti-corrosion tube 108 can increase the corrosion resistance and overall strength of the rubber hose 107. The rat-proof ring 105 is a metal hose that can be bent along with the rubber hose 107 and is more adaptable to actual installation conditions. The provision of multiple anti-slip rings 106 increases the friction between the rat-proof ring 105 and the anti-corrosion tube 108, ensuring that the rat-proof ring 105 will not fall off easily, thereby better protecting each of the sleeves 111. The cable paste 110 can protect the sleeve 111 and also allow the sleeve 111 to have a sliding characteristic. When a mouse bites through the rat-proof ring 105, it will not continue to bite the sleeve 111 due to the presence of the cable paste 110, thereby not affecting the normal use of the line 112.
