[0002] Communication equipment rooms typically require pre-drilled holes to facilitate the entry and exit of cables and fiber optic cables. However, gaps exist between the cables and the holes, necessitating the use of sealing structures to enclose these gaps and achieve fire and water resistance, thus preventing external interference with the equipment within the equipment room.

[0003] In related technologies, retractable blocks are used to seal between cables and holes. However, the diameter of cables with different functions varies greatly, and the retractable block has a limited retraction range.

[0039] In related technologies, patent document CN219041899U discloses a communication base station feeder window installation device, including a mounting frame body. Multiple feeder holes are evenly distributed on one side of the mounting frame body. A rotating frame is provided on one side of each feeder hole, and an elastic flexible tube is provided on one side of the rotating frame. An inlet pipe is located at the center of the rotating frame, and a moving ring is fixedly connected to one end of the inlet pipe. An outlet pipe is located at the center of the moving ring, and three retraction blocks are fixedly connected to the outer wall of one end of the outlet pipe. A limiting groove adapted to the retraction blocks is fixedly connected to the side wall of the feeder hole. The aforementioned patent document discloses a technical solution that achieves sealing and protection of the feeder by setting up an inlet pipe, a moving ring, an outlet pipe, retraction blocks, and an elastic rubber membrane. It also discloses a technical solution that achieves filling between the inlet hole and the mounting frame body by setting up an elastic flexible tube, a rotating frame, and a moving groove.

[0040] However, the fiber optic cables in existing conventional business computer rooms have between 24 and 288 cores. The diameter of these different cables also varies considerably. The fire and water resistance performance still needs improvement when using shrink-block sealing technology.

[0041] In the technical solutions of the related technologies, the shrinkage deformation range of the shrinkage block is limited, and the deformation of the elastic hose and elastic film after being squeezed is uncontrollable. The technical solutions of the related technologies cannot completely cover the outside of the small diameter optical cable, and there are gaps between the elastic rubber mold and the optical cable, resulting in poor fireproof and waterproof performance.

[0042] In order to meet the technical needs and considerations for solving the above-mentioned technical problems, this application provides a cable hole sealing device.

[0043] Figure 1 This invention illustrates the installation structure of a cable hole sealing device 100 provided in the first aspect embodiment of this application. Figure 2 It shows Figure 1 The enlarged structure of the cable hole sealing device 100 in the middle, Figure 7 It shows Figure 1 An enlarged structural diagram of the sealing base 10a in the diagram.

[0044] Please see Figure 1 , Figure 2 and Figure 7 In one aspect, embodiments of this application provide a cable hole sealing device 100, including a sealing base 10a and at least one stranded tube 20.

[0045] The sealing base 10a includes at least one through-hole 10, the cable hole 10 including a first opening 11 and a second opening 12 located on opposite sides of the sealing base 10a.

[0046] At least one twisted tube 20 corresponds to one cable hole 10 and passes through the cable hole 10. The twisted tube 20 includes a rotating structure 21, a fireproof flexible tube 22 and a limiting structure 23 connected in sequence.

[0047] In this configuration, at least a portion of the limiting structure 23 is embedded in the second opening 12, and the limiting structure 23 is fixed to the cable hole 10 in the circumferential direction. At least a portion of the rotating structure 21 is embedded in the first opening 11, and the rotating structure 21 is capable of rotating in the circumferential direction.

[0048] The cable hole sealing device 100 provided in the first aspect of this application has a limiting structure 23 that is at least partially embedded in the second opening 12 to fix and restrict rotation in the circumferential direction, while the rotating structure 21 that is at least partially embedded in the first opening 11 can rotate in the circumferential direction. The relative rotational movement of the limiting structure 23 and the rotating structure 21 will twist and tighten the fireproof hose 22 in the middle and restore it to its original state, thereby blocking and restoring the internal channel of the twisted tube 20. After the fireproof hose 22 is twisted and tightened, it can tightly wrap cables of various diameters, thereby further improving the fireproof and waterproof performance.

[0049] Optionally, the twisted tube 20 can be quickly installed on the cable hole 10 of the sealing base 10a during the initial construction of the computer room. When there is no need for cables, optical cables, or other cables to extend outside the computer room through the hole during the initial construction phase, the arrangement of the twisted tube 20 can also achieve the twisting and tightening of the fireproof flexible tube 22 in the middle through the relative movement of the limiting structure 23 and the rotating structure 21, thereby isolating both ends of the fireproof flexible tube 22 and sealing the cable hole 10 of the sealing base 10a. The cable hole sealing device 100 can prevent the spread of flames and smoke through the twisted tube 20 during a fire during the initial construction phase, and prevent rainwater from flowing into the computer room along the cables. It eliminates the need for additional plugs to seal the first opening 11 and the second opening 12, further improving product integration and thus further reducing manufacturing costs.

[0050] Optionally, when the rotating structure 21 stops rotating relative to the fireproof hose 22 of the twisted pipe 20 and is not subjected to external force, the fireproof hose 22 can automatically untangle and restore its original state without applying additional external force, relying on the elastic potential energy stored by the deformation generated during the previous twisting.

[0051] Optionally, when the rotating structure 21 stops rotating relative to the fireproof hose 22 of the twisted pipe 20, the operator applies an additional thrust to the opposite direction of the previous relative rotation of the rotating structure 21 to help the fireproof hose 22 untangle and return to its original state, so that the interior of the fireproof hose 22 is reconnected.

[0052] Optionally, the rotating structure 21 of the twisted pipe 20 rotates clockwise, the fireproof hose 22 in the middle is twisted and tightened, the internal channel of the fireproof hose 22 is blocked, the rotating structure 21 of the twisted pipe 20 rotates counterclockwise, the fireproof hose 22 is untwisted and restored to its original state, and the internal channel of the fireproof hose 22 is reconnected.

[0053] Optionally, the rotating structure 21 of the twisted pipe 20 rotates counterclockwise, the fireproof hose 22 in the middle is twisted and tightened, the internal channel of the fireproof hose 22 is blocked, the rotating structure 21 of the twisted pipe 20 rotates clockwise, the fireproof hose 22 is untwisted and restored to its original state, and the internal channel of the fireproof hose 22 is reconnected.

[0054] Please continue reading. Figure 2 In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the rotating structure 21 includes a rotating part 211 disposed on the side of itself away from the fireproof hose 22. The rotating part 211 is located on the side of the rotating structure 21 away from the fireproof hose 22. At least a portion of the rotating part 211 is embedded in the first opening 11 and another portion of the rotating part 211 extends out of the first opening 11. The rotating part 211 includes a plurality of anti-slip protrusions 211a disposed along its periphery.

[0055] The cable hole sealing device 100 provided in the first aspect of this application allows the operator to control the rotation of the entire rotating structure relative to the limiting structure 23 by rotating the rotating part 211. The anti-slip protrusions 211a on the rotating part 211 can achieve the anti-slip function, making it convenient for the operator to operate the rotating part 211.

[0056] Optionally, the portion of the rotating part 211 that is embedded in the first opening 11 can be slidably connected to the first opening 11 to facilitate the operator to repair or replace the rotating structure 21.

[0057] Figure 4 It shows Figure 2 The cross-sectional structure along the AA direction.

[0058] Please see Figure 4 In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the rotating structure 21 further includes a positioning part 212, which is located on the side of the rotating structure 21 near the fireproof hose 22. The rotating structure 21 is engaged and fixed with the fireproof hose 22 on the side of the positioning part 212 away from the rotating part 211. The sealing base 10a also includes a positioning component 13 disposed around the first opening 11.

[0059] In the working state, the positioning part 212 is embedded in the first opening 11 and fixed in cooperation with the positioning component 13, and the rotating structure 21 is fixed in the circumferential direction with the cable hole 10.

[0060] In the cable hole sealing device 100 provided in the first aspect of this application, in these embodiments, the positioning part 212 of the rotating structure 21 can cooperate with the positioning component 13. After the rotating structure 21 rotates relative to the limiting structure 23, the fireproof hose 22 in the middle is fully twisted and tightened. After the internal channel of the fireproof hose 22 is blocked and the cable is tightly wrapped, the rotating structure 21 is fixed at this position where the fireproof hose 22 is fully twisted and tightened, and the twisted tube 20 is kept in working state for a long time.

[0061] Please continue reading. Figure 4 and Figure 7 In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the cable hole 10 further includes a first countersunk hole 101 and a cable inlet hole 102 that are sequentially connected along the direction from the first opening 11 to the second opening 12, wherein the diameter of the cable inlet hole 102 is smaller than the diameter of the first countersunk hole 101.

[0062] In the working state, at least part of the positioning part 212 is embedded in the inlet hole 102. The sealing base 10a also includes a mounting groove 10b located around the first opening 11. The positioning component 13 is disposed in the mounting groove 10b. The mounting groove 10b is connected to the first countersunk hole 101. The positioning component 13 also includes a first elastic element 131 and a positioning element 132. The positioning element 132 is embedded in the first countersunk hole 101. The positioning element 132 includes a support lug 1321 protruding from the side wall of the first countersunk hole 101. The support lug 1321 abuts against the positioning part 212. The side of the positioning element 312 away from the support lug 1321 is elastically connected to the side wall of the mounting groove 10b through the first elastic element 131.

[0063] The cable hole sealing device 100 provided in the first aspect of this application, in these embodiments, the positioning part 212 can be partially embedded in the cable inlet hole 102, which facilitates the operator to install and position the rotating structure 21 in the cable hole 10, and the elastic potential energy generated by the extrusion deformation of the first elastic member 131 can help the positioning member 132 to always maintain the contact state with the positioning part 212, so as to keep the twisted tube 20 in the working state for a long time.

[0064] The first countersunk hole 101 is an opening shape whose diameter gradually narrows from one side of the first opening 11. The shape of the first countersunk hole 101 can help the rotating structure 21 to be pre-aligned before it is installed on one side of the first opening 11, which makes it convenient for the operator to install and position the rotating structure 21 in the cable hole 10.

[0065] The diameter of the inlet hole 102 is smaller than the diameter of the first countersunk hole 101, which further helps the positioning part 212 of the rotating structure 21 to be accurately positioned to partially embed into the inlet hole 102, making it convenient for operators to install and position the rotating structure 21 in the cable hole 10.

[0066] When the fireproof flexible hose 22 in the middle is fully twisted and tightened, and the internal channel of the fireproof flexible hose 22 is blocked and the cable is tightly wrapped, it is fixed by abutting the support ear 1321 of the positioning member 132 with the positioning part 212. The compression of the support ear 1321 of the positioning member 132 causes compression deformation of the first elastic member 131. The elastic potential energy generated by the compression deformation of the first elastic member 131 can help the support ear 1321 of the positioning member 132 to always maintain abutting state with the positioning part 212, keeping the twisted tube 20 in working state for a long time.

[0067] Optionally, the positioning part 212 is embedded in the wire inlet hole 102 and slidably connected to the inner wall of the wire inlet hole 102, so as to facilitate the operator to repair or replace the rotating structure 21.

[0068] Figure 5 It shows Figure 1 An enlarged structure of one of the stranded tubes 20.

[0069] Please see Figure 4 and Figure 5 In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the positioning part 212 further includes a plurality of limiting protrusions 212a arranged along its own periphery and a positioning groove 212b arranged between two adjacent limiting protrusions 212a.

[0070] In the working state, the positioning element 132 is embedded in the positioning groove 212b.

[0071] The cable hole sealing device 100 provided in the first aspect of this application has a better fixing effect in these embodiments, wherein the positioning member 132 can be embedded in the positioning groove 212b between the limiting protrusions 212a.

[0072] Figure 6 It shows Figure 5 Local cross-sectional structure along the BB direction.

[0073] Please continue reading. Figures 4 to 6 Optionally, the lug 1321 also includes a meshing surface 1321a and a blocking surface 1321b disposed opposite to each other. The lug 1321 is embedded in the positioning groove 212b, the meshing surface 1321a meshes with the limiting protrusion 212a, and the blocking surface 1321b abuts against the limiting protrusion 212a.

[0074] In these alternative embodiments, the lug 1321 is embedded in the positioning groove 212b, which only limits the rotation of the rotating structure 21 toward the blocking surface 1321b, without affecting the rotation of the rotating structure 21 toward the meshing surface 1321a.

[0075] When the first elastic member 131 does not deform, the lug 1321 of the positioning member 132 is embedded in the positioning groove 212b. When the rotating structure 21 rotates toward the meshing surface 1321a, the limiting protrusion 212a can mesh with the meshing surface 1321a, so that the positioning member 132 is subjected to force and compresses the first elastic member 131, the first elastic member 131 deforms, and the lug 1321 retracts toward the inside of the mounting groove 10b.

[0076] When the limiting protrusion 212a rotates away from the opening of the mounting groove 10b, the positioning member 132 is ejected again by the elastic potential energy of the first elastic member 131, and the support ear 1321 is re-embedded in the next positioning groove 212b between the limiting protrusion 212a and the next adjacent limiting protrusion 212a. The above steps are repeated without affecting the rotation of the rotating structure 21 toward the meshing surface 1321a.

[0077] However, when the rotating structure 21 rotates toward the blocking surface 1321b, or when the elastic potential energy stored by the deformation generated by the twisting of the intermediate fireproof hose 22 causes the rotating structure 21 to rotate toward the blocking surface 1321b, the limiting protrusion 212a can abut against the blocking surface 1321b, the positioning member 132 cannot be subjected to force and compress the first elastic member 131, and the support ear 1321 cannot retract toward the inside of the mounting groove 10b, thereby preventing the rotating structure 21 from rotating toward the blocking surface 1321b and playing a positioning role.

[0078] Please continue reading. Figure 2 , Figure 4 and Figure 7 In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the positioning member 132 further includes a toggle end 1322 protruding from the mounting groove 10b on one side of the first opening 11.

[0079] The cable hole sealing device 100 provided in the first aspect of this application, in these embodiments, when it is necessary to release the working state of the twisted tube 20, the operator only needs to move the moving end 1322 of the positioning member 132, which can also retract the support ear 1321 of the positioning member 132 toward the mounting groove 10b. Under the action of the elastic potential energy stored in the deformation generated by its own twisting, or by the operator manually rotating the rotating structure 21 in the opposite direction, the fireproof hose 22 can be released from twisting and restored to its original state, thereby reconnecting the internal channel of the fireproof hose 22 and releasing the working state of the twisted tube 20.

[0080] Optionally, when it is necessary to twist and tighten the fireproof hose 22 in the middle so that the twisted tube 20 is back in working condition, the operator can also turn the turning end 1322 to make the support ear 1321 of the positioning member 132 retract into the mounting groove 10b. By rotating the rotating structure 21, the fireproof hose 22 can also be twisted and tightened again. After twisting and tightening, the turning end 1322 is released, and the support ear 1321 falls down and re-embeds into the positioning groove 212b, so that the twisted tube 20 can remain in working condition for a long time.

[0081] Figure 3 It shows Figure 1 An enlarged view of the cable sealing device from another angle. Figure 8 It shows Figure 1 An enlarged structural diagram of the sealing base 10a from another angle.

[0082] Please continue reading. Figure 3 , Figure 4 and Figure 8In some embodiments of the cable hole sealing device 100 provided in the first aspect of this application, the limiting structure 23 further includes a plurality of through holes 231 arranged along its periphery, and the cable hole 10 further includes a second countersunk hole 103 and a wire inlet hole 102 arranged sequentially along the direction from the second opening 12 to the first opening 12, wherein the diameter of the wire inlet hole 102 is smaller than the diameter of the second countersunk hole 103.

[0083] The second countersunk hole 103 also includes a first sidewall 103a, a second sidewall 103b and a third opening 103c connected in sequence. The third opening 103c is connected to the inlet hole 102. The second countersunk hole 103 also includes multiple sliding pillars 103d fixedly connected to the second sidewall 103b. The through hole 231 corresponds to the sliding pillar 103d one by one, and the sliding pillar 103d is disposed through the through hole 231 so that the limiting structure 23 is slidably connected to the second countersunk hole 103 along the axial direction of the second countersunk hole 103.

[0084] The cable hole sealing device 100 provided in the first aspect of this application has a limiting structure 23 that is slidably connected to a sliding column 103d in the second countersunk hole 103 through a through hole 231. This not only achieves circumferential fixation and restricts the rotation of the limiting structure 23, but also allows the limiting structure 23 to be slidably connected to the second countersunk hole 103 in the axial direction.

[0085] When the middle fireproof hose 22 is twisted and tightened, the fireproof hose 22 will be partially compressed in the axial direction. By setting a limiting structure 23 that is slidably connected to the second countersunk hole 103 in the axial direction, a large pulling force is avoided when the middle fireproof hose 22 is twisted and tightened, thus avoiding the risk of the fireproof hose 22 being damaged by a large pulling force.

[0086] The second countersunk hole 103 is an opening shape whose diameter gradually narrows from one side of the first opening 11. The shape of the second countersunk hole 103 can help the limiting structure 23 to be pre-aligned before it is installed on one side of the second opening 12, which makes it convenient for the operator to install and position the limiting structure 23 in the cable hole 10.
