Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically to an installation structure for a cable duct sealing component. Background Technology

[0002] Cable duct sealing is a duct sealing technology. Its main functions are to prevent sewage and rainwater from flowing into the duct, causing the cable to operate under danger due to long-term immersion in water; to prevent sewage and rainwater from seeping through the duct and endangering the operational safety of adjacent inspection wells or substations / switching stations; to prevent sewage from bringing in silt and garbage, clogging the cable duct and affecting subsequent line inspection and maintenance; and to prevent small animals from entering the cable duct, gnawing and damaging the cable, and breeding and roaming inside the duct.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221747943U) discloses an installation structure for a cable duct sealing component, comprising a chassis. A sealing mechanism is installed on the chassis wall. The sealing mechanism is composed of a rubber ring cavity, a disc, a sealing disc, threaded rods, threaded sleeves, and through holes. The chassis wall and the disc wall are bonded together via the rubber ring cavity. Several sets of symmetrical threaded rods are welded to the disc wall. Several sets of symmetrical through holes are opened on the sealing disc wall. Several sets of threaded rods pass through several sets of through holes. Threaded sleeves are threadedly connected to the rod walls of several sets of threaded rods, and the threaded sleeves are located on one side of the sealing disc.

[0004] In the aforementioned patent, the rubber ring cavity is inflated to expand and seal the cable conduit. Several symmetrical threaded rods are welded to the disc wall, and these rods pass through the through-hole, allowing the sealing disc to seal the circular groove. The threaded rods are connected to a threaded sleeve to fix the sealing disc, thus sealing the cable conduit. However, it is inconvenient to fit the base and disc onto the rubber ring cavity and cable, which may prevent the rubber ring cavity from fully expanding to the required position, affecting the sealing effect between it and the cable conduit. Inadequate sealing may allow moisture, dust, or other impurities to enter the cable conduit, damaging the cable.

[0005] Therefore, this utility model provides an installation structure for a cable duct sealing component to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides an installation structure for a cable duct sealing component, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cable duct sealing installation structure includes a lower seal 1, an upper seal 2 hinged to the lower seal 1, an installation cavity 3 opened inside the lower seal 1 and the upper seal 2, a rubber ring cavity 9 set inside the installation cavity 3, and a fixing mechanism set on one side of the lower seal 1 for quickly fitting the cable into the rubber ring cavity 9.

[0028] The fixing mechanism includes a limiting block 4 fixedly installed on the upper seal 2, a limiting chamber 5 opened inside the lower seal 1, a spring 6 disposed inside the limiting chamber 5, an insert 7 slidably installed inside the limiting chamber 5, and a slide rod 8 fixedly installed on the insert 7.

[0029] The lower seal 1 has a limiting groove for the sliding of the limiting block 4. Two inserts 7 are respectively set on both sides of the limiting block 4. One end of the spring 6 is fixedly connected to the inner wall of one side of the limiting chamber 5.

[0030] The other end of the spring 6 is fixedly connected to one side of the insert block 7. The insert block 7 passes through the limiting chamber 5. The limiting block 4 has slots on both sides for the insert block 7 to be inserted. The slide rod 8 passes through the limiting chamber 5. The lower seal 1 has a sliding groove for the slide rod 8 to slide.

[0031] When using this cable duct sealing installation structure, the cable is passed through the rubber ring cavity 9. First, the upper seal 2 and lower seal 1 are opened. Then, the cable and rubber ring cavity 9 are placed inside the installation cavity 3. After that, the upper seal 2 and lower seal 1 are closed, allowing the limiting block 4 to slide along the limiting groove. When the limiting block 4 contacts the two insert blocks 7 during its sliding process, it first contacts the inclined surface of the insert blocks 7, thereby squeezing the insert blocks 7 to both sides. The movement of the insert blocks 7 compresses the spring 6. When the insert blocks 7 are at the same horizontal line as the slot inside the limiting block 4, the spring 6 pushes the insert blocks 7 along the inner wall of the limiting chamber 5 due to its own elastic force. The movement allows the insert 7 to be inserted into the slot, thereby limiting and fixing the limiting block 4, and fixing the upper seal 2 and the lower seal 1. The operation is simple and does not require the use of bolts or other fasteners for fixation, saving time and effort. At the same time, the setting of the rubber ring cavity 9 improves the sealing performance of the cable pipe sealing installation structure and prevents water from entering the cable pipe. In addition, when it is necessary to remove the cable and the rubber ring cavity 9, the slide bar 8 is manually slid along the slide groove to both sides, so that the insert 7 is pulled out from the inside of the slot, stopping the limiting block 4. At this time, the upper seal 2 and the lower seal 1 can be opened, and then the cable and the rubber ring cavity 9 can be removed.

[0032] Furthermore, in order to seal and plug the cable conduit, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a sealing disc 10 is provided on one side of the lower sealing member 1 and the upper sealing member 2. Multiple first bolts 11 are rotatably connected inside the sealing disc 10. A threaded groove adapted to the first bolts 11 is opened on one side of the lower sealing member 1 and the upper sealing member 2.

[0033] The sealing disc 10 has a threaded post 12 screwed inside, and the sealing disc 10 has a threaded hole 14 that matches the threaded post 12. A handle 13 is fixedly connected to one side of the threaded post 12.

[0034] The lower seal 1 is internally connected to an intake valve pipe 15, which passes through the lower seal 1. One side of the rubber ring cavity 9 is fixedly connected to one side of the intake valve pipe 15.

[0035] When using this cable duct sealing installation structure, to seal the cable duct, the first bolt 11 is rotated, causing it to be screwed into the threaded groove on one side of the lower seal 1 and the upper seal 2, further fixing the lower seal 1 and the upper seal 2 and improving the sealing performance. By rotating the handle 13, the threaded post 12 is driven to rotate in the threaded hole 14 inside the sealing disc 10. The air inlet valve pipe 15 facilitates the inflation of the rubber ring cavity 9, causing the rubber ring cavity 9 to expand, further improving the sealing performance of the cable duct sealing installation structure, preventing water from entering the cable duct, and ensuring the normal operation of the cable duct.

[0036] To facilitate the installation of the lower seal 1 and the upper seal 2 inside the cable conduit, such as... Figure 1 , Figure 2 and Figure 3 As shown, a connecting plate 16 is provided on the side of the lower seal 1 and the upper seal 2 away from the sealing plate 10. Multiple second bolts 17 are rotatably connected inside the connecting plate 16. A threaded groove adapted to the second bolts 17 is opened on one side of the lower seal 1 and the upper seal 2.

[0037] During use, this cable duct sealing installation structure allows for easy installation of the lower seal 1 and upper seal 2 inside the cable duct via the screw connection between the second bolt 17 and the threaded groove, improving installation convenience. Simultaneously, the connecting disc 16 enhances the connection stability between the lower and upper seals and the cable duct, further improving the overall sealing effect. During installation, simply align the connecting disc 16 with the opening of the cable duct and then rotate the second bolt 17 for quick installation, significantly saving installation time and labor costs.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
