Description

Technical Field

[0001] This invention relates to the field of fiber optic sleeve technology, specifically to a high-sealing open-type modular fiber optic sleeve. Background Technology

[0002] Fiber sleeving, also known as glass fiber sleeving, is a sleeving made of reinforced braided glass fiber. Its insulation capabilities and low price make it the most economical choice for protecting hoses and cables. Fiber sleeving has high temperature resistance, thermal insulation, flame retardancy, and chemical stability. It can protect the hoses and cables it covers, ensuring that they maintain their strength, toughness, and abrasion resistance at high temperatures and preventing them from being corroded by most chemicals.

[0003] When installing fiber optic sleeves on conduits or cables, the sleeves only have openings at both ends, allowing the conduits or cables to be inserted from one end. Once the conduits and cables are installed, it is difficult to cover them completely, causing inconvenience. Furthermore, if the middle of the sleeve is damaged, the entire sleeve needs to be removed and reinstalled, which is cumbersome and increases the cost of replacing the sleeve.

[0004] In response to the existing problems, there is an urgent need to innovate based on the existing fiber sheath. Summary of the Invention

[0005] The purpose of this invention is to provide a highly airtight open-type modular fiber optic sleeve to solve the problems mentioned in the background art. When installing fiber optic sleeves on the surface of conduits or cables, the fiber optic sleeve only has openings at both ends, allowing the conduit or cable to be inserted from one end. After the conduit or cable is installed, it is difficult to cover the outside of the conduit or cable, causing inconvenience in the installation of the fiber optic sleeve. Furthermore, when the middle of the fiber optic sleeve is damaged, the entire fiber optic sleeve needs to be removed and reinstalled, which is cumbersome and increases the replacement cost of the fiber optic sleeve.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-sealing open-type modular fiber sleeve, comprising a sleeve body and a connector, wherein the sleeve body is provided with a connector on its side, and the connector is provided with a butt joint on its side.

[0012] As an alternative embodiment of the high-sealing open-type modular fiber sleeve of the present invention, the first cavity is interconnected with the connecting conduit, and the gas filled in the first cavity is an inert gas, and the volume of the first cavity is greater than the volume of the second cavity, while the interior of the second cavity is filled with dry powder.

[0013] As an optional solution of the high-sealing open-type modular fiber sleeve of the present invention, wherein: the first airbag is provided with a limiting strip on its side, and the limiting strip is set at an equal angle with respect to the sleeve body, and the side view of the limiting strip is set with an arc-shaped structure, while the inner side of the sleeve body is provided with a limiting groove.

[0014] As an optional solution of the high-sealing open-type modular fiber sleeve of the present invention, wherein: a second airbag is provided on the outer side of the docking sleeve, and a guide tube is provided on the outer wall of the second airbag, and the second airbag and the guide tube are interconnected, and the guide tube is set at an equal angle.

[0015] As an optional embodiment of the high-sealing open-type modular fiber sleeve of the present invention, wherein: a connecting spring is fixedly connected to the outer wall of the movable block, and the connecting spring is equidistant from the movable block, and a docking piece is fixedly connected to the end of the connecting spring, while a sealing airbag is provided on the inner side of the docking piece.

[0016] As an optional embodiment of the high-sealing open-type modular fiber sleeve of the present invention, wherein: the outer surface of the sealing airbag is in contact with the outer surface of the connector, and the connector is fixedly connected to the sleeve body, and the outer wall of the connector is provided with a locking mechanism.

[0017] As an optional solution for the high-sealing open-type modular fiber sleeve of the present invention, the locking mechanism includes a locking block, a third airbag and a sliding block, wherein the locking block is provided with a third airbag inside, and a sliding block is provided on the top of the third airbag.

[0018] As an alternative embodiment of the high-sealing open-type modular fiber sleeve of the present invention, wherein: the top of the third airbag is in contact with the bottom of the sliding block, the sliding block is nested inside the locking block, and the end of the sliding block is in contact with the end of the movable block.

[0019] As an alternative to the high-sealing open-type modular fiber sleeve of the present invention, the third airbag is provided with an air guide tube on its side, and the third airbag is interconnected with the second airbag through the air guide tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This high-sealing open-type modular fiber optic sleeve is equipped with connectors and mating parts. The connectors and mating parts are provided on the sleeve body. The connectors are equipped with locking mechanisms that lock into the mating parts to achieve quick fixation of the connectors and mating parts. The movable block inside the locking mechanism moves to embed into the mating parts, achieving stable fixation of the connectors and mating parts. Furthermore, the quick-release open-type structure makes it easy to install the fiber optic sleeve on the outer surface of the cable without changing the cable installation position, making the installation of the fiber optic sleeve simpler and more convenient.

[0022] 2. This high-sealing open-type modular fiber optic sleeve is equipped with a docking sleeve. Utilizing a second airbag on the docking sleeve, and with the thickness of the docking sleeve being less than the thickness of the sleeve body, it is easy for the tail of the subsequent sleeve body to nest onto the docking sleeve at the end of the previous sleeve body. When the cable is wrapped and fitted, the second airbag on the docking sleeve is simultaneously compressed. The second airbag is connected to the first cavity inside the first airbag through a conduit, causing the first cavity inside the first airbag to expand. Multiple first airbags are provided, and the first cavities inside the first airbags are interconnected through connecting conduits. By utilizing the expansion of the first cavities inside multiple first airbags, the shape of the first airbag changes and it is tightly connected to the protective cable, improving the tightness of the wrapping. This positions the protective cable and the sleeve body, preventing relative sliding between the two and avoiding inconvenience caused by subsequent installation and use.

[0023] 3. The high-sealing open-type modular fiber sleeve is provided with a first cavity and a second cavity. The first airbag is divided into a first cavity and a second cavity by a partition layer inside the first airbag. The first cavity is filled with inert gas. When the first airbag is exposed to an open flame, the first cavity will burst, and the inert gas will be ejected, squeezing out the oxygen in the space of the protective cable. By isolating the oxygen, it achieves a preliminary flame-retardant effect. When the second cavity is exposed to an open flame, it will also burst, and the dry powder filled in the second cavity will be sprayed into the space around the protective cable. The volatile decomposition products of inorganic salts in the dry powder will have a chemical inhibition and side catalytic effect with the free radicals or active groups produced by the fuel during combustion, interrupting the chain reaction of combustion. At the same time, the powder of the dry powder falls on the surface of the combustible material, undergoes a chemical reaction, and forms a glassy covering layer under high temperature, thereby isolating oxygen and achieving a flame-retardant effect.

[0024] 4. This high-sealing open-type modular fiber sleeve is equipped with a third airbag. When the first airbag is compressed, the gas inside the first airbag will simultaneously enter the third airbag through the air guide tube, causing the third airbag to inflate and drive the sliding block to slide within the locking block. This allows the sliding block to embed into the docking part, locking the connector and the docking part together to prevent accidental disengagement. When the sliding block moves, it will compress the movable block and the connecting spring. When the third airbag resets, the reset force of the connecting spring will drive the movable block to move, causing the movable block to compress the sliding block, causing the sliding block to retract and reset, locking the connector and the docking part together, facilitating the separation and disassembly of the connector and the docking part.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] This embodiment aims to facilitate a solution to the problem of how to quickly apply a limiting sleeve without changing the position of the cable. Please refer to [link / reference needed]. Figures 1 to 5 and Figure 9 This invention provides a technical solution: a high-sealing open-type modular fiber duct, comprising a duct body 1 and a connector 2, wherein the connector 2 is provided on the side of the duct body 1, and a mating part 3 is provided on the side of the connector 2; further comprising:

[0038] A connecting groove 4 is formed on the inner surface of the sleeve body 1, and a first airbag 5 is provided on the inner side of the connecting groove 4, and a connecting conduit 6 is provided on the side of the first airbag 5. The first airbag 5 and the connecting groove 4 are arranged in a one-to-one correspondence, and the first airbag 5 is arranged at equal angles. A protective cable 7 is provided on the outer side of the first airbag 5.

[0039] A connecting sleeve 8 is provided at the end of the sleeve body 1, and the connecting sleeve 8 and the sleeve body 1 are integrally formed. A connecting groove 9 is provided on the outer surface of the connecting sleeve 8. The connecting groove 9 is set at an equal angle with respect to the connecting sleeve 8. A positioning strip 11 is nested inside the connecting groove 9. The number of positioning strips 11 corresponds one-to-one with the number of connecting grooves 9. A locking ring 12 is fixedly connected to the outer wall of the positioning strip 11.

[0040] Movable block 16 is movably installed inside the docking part 3;

[0041] The first airbag 5 has a limiting strip 14 on its side, and the limiting strip 14 is set at an equal angle with respect to the sleeve body 1. The side view of the limiting strip 14 is set in an arc shape. At the same time, the inner side of the sleeve body 1 has a limiting groove 15. The outer side of the connecting sleeve 8 has a second airbag 10, and the outer wall of the second airbag 10 has a guide tube 13. The second airbag 10 and the guide tube 13 are interconnected, and the guide tube 13 is set at an equal angle.

[0042] First, place the sleeve body 1 on the outside of the protective cable 7, and pull the connector 2 on the sleeve body 1. The connector 2 is connected to the locking mechanism 19, so that the connector 2 drives the locking mechanism 19 to move around the protective cable 7, and finally the locking mechanism 19 is locked into the docking part 3 at the other end of the sleeve body 1, so as to achieve simple locking of the connector 2 and the docking part 3. The sleeve body 1, connector 2 and docking part 3 are used to cover the protective cable 7. The open docking structure makes it simpler and more convenient to put the fiber sleeve on the cable.

[0043] The end of the sleeve body 1 is provided with a docking sleeve 8. By allowing the end of the next sleeve body 1 to be fitted onto the docking sleeve 8 on the previous sleeve body 1, and allowing the limiting strip 14 to be embedded in the docking groove 9 on the docking sleeve 8, the positions of the two sleeve body 1 sections are limited. The protective cable 7 is covered by connecting the connector 2 and docking piece 3 on the next sleeve body 1. By using modular segmented installation, if a section is damaged, only the sleeve body 1 and docking sleeve 8 of that section need to be replaced, effectively reducing replacement costs. The docking sleeve 8 at the end of the last sleeve body 1 is provided with a locking ring 12. The positioning strip 11 on the locking ring 12 is embedded in the docking groove 9. The connection method between the locking ring 12 and the docking sleeve 8 is the same as the connection method between the next sleeve body 1 and the previous docking sleeve 8, and the opening of the locking ring 12 is locked by a screw.

[0044] When the locking ring 12 and the docking sleeve 8 are docked, the second airbag 10 on the docking sleeve 8 will be squeezed during the locking docking with the next sleeve body 1 and the previous docking sleeve 8. The second airbag 10 is connected to the first cavity 503 in the first airbag 5 through the guide tube 13. Multiple guide tubes 13 are provided to allow the gas in the second airbag 10 to enter the first cavity 503 in multiple first airbags 5 evenly, causing the first cavity 503 to expand and change the shape of the first airbag 5, so that the first airbag 5 fits tightly with the protective cable 7, improving the tightness of the wrapping, and positioning the protective cable 7 and the sleeve body 1 to avoid relative sliding between the two, which would cause inconvenience to subsequent installation and use. When the second airbag 10 is squeezed and deformed, the docking gap will be reduced at the same time, improving the docking seal.

[0045] Example 2

[0046] This embodiment aims to facilitate a solution to the problem of how to improve the fire-retardant performance of fiber optic sleeves. This embodiment is an improvement based on Embodiment 1. For details, please refer to [link / reference needed]. Figure 2 and Figures 6 to 7 The first airbag 5 includes an airbag shell 501, a partition layer 502, a first cavity 503, and a second cavity 504. The inner wall of the airbag shell 501 is provided with the partition layer 502, and the first cavity 503 is provided on one side of the partition layer 502. The second cavity 504 is provided on the other side of the partition layer 502. The first cavity 503 is connected to the connecting conduit 6. The gas filled in the first cavity 503 is an inert gas. The volume of the first cavity 503 is larger than the volume of the second cavity 504. The second cavity 504 is filled with dry powder.

[0047] The internal cavity of the first airbag 5 is divided into a first cavity 503 and a second cavity 504 by the partition layer 502 inside the first airbag 5. The gas flowing in the first cavity 503 and the second airbag 10 is an inert gas. When a fire occurs at the protective cable 7, the flame will scorch the airbag shell 501 inside the first airbag 5, causing the first cavity 503 to burst. Because the gas in the first cavity 503 is an inert gas, the inert gas in the first cavity 503 will be ejected outward, squeezing out the oxygen in the space around the protective cable 7 and isolating the oxygen around the protective cable 7. In the early stage of the fire, it plays a flame-retardant role and protects the protective cable 7.

[0048] Furthermore, when an open flame is applied to the second cavity 504, it will cause the second cavity 504 to burst. The second cavity 504 contains dry powder, which is sprayed around the protective cable 7. The volatile decomposition products of inorganic salts in the dry powder have a chemical inhibition and side catalytic effect with the free radicals or active groups produced by the fuel during combustion, which interrupts the chain reaction of combustion. At the same time, the powder falls on the surface of the combustible material, undergoes a chemical reaction, and forms a glassy covering layer under high temperature, thereby isolating oxygen and achieving a flame-retardant effect.

[0049] Example 3

[0050] This embodiment aims to facilitate a solution to the problem of improving both the tightness and sealing performance of the connection. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figures 6 to 8 The locking mechanism 19 includes a locking block 191, a third airbag 192, and a sliding block 193. The third airbag 192 is disposed inside the locking block 191, and the sliding block 193 is disposed on the top of the third airbag 192. The top of the third airbag 192 and the bottom of the sliding block 193 fit together. The sliding block 193 is nested inside the locking block 191, and the end of the sliding block 193 fits together with the end of the movable block 16. An air guide tube 20 is disposed on the side of the third airbag 192, and the third airbag 192 is connected to the second airbag 10 through the air guide tube 20.

[0051] When the second airbag 10 is compressed, the gas inside the second airbag 10 will simultaneously enter the third airbag 192 through the air guide tube 20, causing the third airbag 192 to inflate. The third airbag 192 will drive the sliding block 193 within the locking block 191, allowing the sliding block 193 to embed into the docking member 3, thereby locking the connection between the connector 2 and the docking member 3, improving the tightness of the connection between the connector 2 and the docking member 3, and effectively preventing accidental separation. When the connector 2 and the docking member 3 are docked, the sealing airbag 18 will be compressed at the same time. The deformation of the sealing airbag 18 will reduce the connection gap between the two and improve the docking sealing performance.

[0052] Example 4

[0053] This embodiment aims to facilitate a solution to the problem of how to achieve docking lock and automatic release. This embodiment is an improvement on Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 6 and Figure 7A connecting spring 17 is fixedly connected to the outer wall of the movable block 16, and the connecting spring 17 is arranged at equal distances from the movable block 16. A docking part 3 is fixedly connected to the end of the connecting spring 17. A sealing airbag 18 is provided on the inner side of the docking part 3. The outer surface of the sealing airbag 18 is in contact with the outer surface of the connecting part 2. The connecting part 2 and the sleeve body 1 are integrated. A locking mechanism 19 is provided on the outer wall of the connecting part 2.

[0054] When the sliding block 193 inside the locking block 191 moves, the sliding block 193 will squeeze the movable block 16, causing the movable block 16 to slide within the connector 2. Simultaneously, as the movable block 16 slides, it will also squeeze the connecting spring 17 at its end. Multiple connecting springs 17 are provided, causing them to contract. When the third airbag 192 inside the locking block 191 deflates and resets, the reset force of the compressed connecting spring 17 on the movable block 16 drives the movable block 16 to move. The end of the movable block 16 and the end of the sliding block 193 press against each other, causing the movable block 16 to move while simultaneously driving the sliding block 193 to move, allowing the sliding block 193 to slide within the locking block 191. This automatically retracts the sliding block 193, releasing it from locking the connector 3 and preventing the connector 2 and connector 3 from being difficult to separate due to the sliding block 193 when subsequently unlocking them.
