Description

Technical Field

[0001] This utility model relates to the field of cable auxiliary device technology, specifically a fireproof sealing auxiliary device for cables. Background Technology

[0002] Fire-stopping auxiliary devices for cables are components used to prevent the spread of flames and smoke when cables pass through holes in walls, floors, etc. They are usually used in conjunction with fire-stopping materials (such as fireproof putty, fireproof bags, fireproof boards, etc.) and their functions include fixing cables, supporting the sealing materials, and enhancing sealing performance and fire resistance.

[0003] However, traditional fireproof sealant sealing requires manual filling, compaction, and shaping, especially in areas with multiple cables or complex gaps. Construction workers need to repeatedly adjust the sealing position, which is time-consuming and labor-intensive. To address these issues, the inventors have proposed an auxiliary fireproof sealing device for cables. Utility Model Content

[0004] To address the cumbersome and inconvenient process of sealing cables with fireproof putty, this utility model aims to provide an auxiliary device for fireproof sealing of cables.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a fireproof sealing auxiliary device for cables, including a wall, a pre-embedded pipe fixedly connected inside the wall, an annular seat covering the outer side of one end of the pre-embedded pipe, an installation groove opened on the inner side of the annular seat, a rubber ring snapped into the installation groove, an annular groove opened inside the annular seat, and a sealing component arranged inside the annular groove.

[0006] Preferably, the sealing assembly includes a turntable rotatably connected inside an annular seat. The turntable has centrally symmetrically distributed guide grooves. A centrally symmetrically distributed fixing frame is fixedly connected inside each annular groove. A telescopic rod is movably inserted inside each fixing frame. An arc-shaped plate is fixedly connected to one end of each telescopic rod, which extends movably into a mounting groove and abuts against a rubber ring. A guide post is fixedly connected to one side of each telescopic rod, and the guide post is movably engaged in the guide groove. A straight groove is formed on one side of the fixing frame, and the guide post is movably engaged in the straight groove. A rotating block is rotatably connected to one side of the annular seat. A threaded rod is rotatably connected to one side of the rotating block. A movable block is threadedly connected to the outer side of the threaded rod. An arc-shaped groove is formed on one side of the annular seat, and the movable block is movably engaged in the arc-shaped groove. The movable block is rotatably connected to the turntable.

[0007] Preferably, the side of the annular seat is fixedly connected to two symmetrically distributed positioning plates, each of which has a positioning hole.

[0008] Preferably, a sealing groove is provided on the side of the annular seat near the pre-embedded pipe, and a sealing ring is provided inside the sealing groove. One end of the pre-embedded pipe is movably inserted into the sealing groove and abuts against the sealing ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. Through the cooperation between the turntable, guide groove, fixed frame, telescopic rod, guide column, arc plate, straight groove, rotating block, threaded rod, moving block and arc groove, the rotating threaded rod drives the moving block to move along the outside of the threaded rod, and drives the turntable connected to the rotating moving block to rotate. Under the cooperation of the guide groove and guide column, multiple arc plates are pushed to move away from or towards the rubber ring. When the arc plates move to one side of the rubber ring, the rubber ring deforms and comes into close contact with the outside of the cable, thereby sealing the gap between the cable and the ring seat, making the sealing operation convenient and quick.

[0011] 2. By placing the annular seat on the outside of one end of the embedded pipe, and simultaneously inserting one end of the embedded pipe into the sealing groove and making it tightly contact the sealing ring, the annular seat is fixed to the wall through the cooperation between the positioning plate and the positioning hole. The installation and disassembly are convenient and quick. Attached Figure Description

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides a fireproof sealing auxiliary device for cables, including a wall 1, a pre-embedded pipe 2 fixedly connected inside the wall 1, an annular seat 3 covering the outer side of one end of the pre-embedded pipe 2, an installation groove 4 opened on the inner side of the annular seat 3, a rubber ring 5 snapped into the inside of the installation groove 4, an annular groove 6 opened inside the annular seat 3, and a sealing component 7 arranged inside the annular groove 6.

[0021] The sealing assembly 7 includes a turntable 71, which is rotatably connected to the inside of the annular seat 3. The turntable 71 has centrally symmetrically distributed guide grooves 72. The annular groove 6 has a centrally symmetrically distributed fixing frame 73 fixedly connected inside. The fixing frame 73 has a telescopic rod 74 movably inserted inside. The ends of the telescopic rods 74 that are close to each other are fixedly connected to an arc plate 76. The arc plate 76 extends movably to the mounting groove 4 and abuts against the rubber ring 5. The telescopic rod 74 has a guide post 75 fixedly connected to one side. The guide post 75 is movably engaged in the guide groove 72.

[0022] By adopting the above technical solution, when the turntable 71 is rotated, the guide groove 72 guides the guide column 75, and at the same time drives multiple guide columns 75 to move away from or closer to the center of the annular seat 3, and drives the telescopic rod 74 to move synchronously along the inside of the fixed frame 73, thereby pushing multiple arc plates 76 to move away from or closer to the rubber ring 5. When the cable pipe is inserted into the inside of the annular seat 3, by moving the arc plates 76 to one side of the rubber ring 5, the rubber ring 5 is deformed and tightly abuts against the outside of the cable, thereby sealing the gap between the cable and the annular seat 3.

[0023] A straight groove 77 is provided on one side of the fixed frame 73, and the guide post 75 is movably engaged in the straight groove 77.

[0024] By adopting the above technical solution and setting the straight groove 77, the movement of the guide post 75 can be easily guided.

[0025] A rotating block 78 is rotatably connected to one side of the annular seat 3, and a threaded rod 79 is rotatably connected to one side of the rotating block 78. A movable block 710 is threadedly connected to the outer side of the threaded rod 79. An arc-shaped groove 711 is opened on one side of the annular seat 3, and the movable block 710 is movably engaged in the arc-shaped groove 711. The movable block 710 is rotatably connected to the turntable 71.

[0026] By adopting the above technical solution, the threaded rod 79 is rotated, which simultaneously drives the moving block 710 to move along the outside of the threaded rod 79, and drives the turntable 71 connected to the moving block 710 to rotate, thereby realizing the driving of the sealing component 7.

[0027] The side of the ring seat 3 is fixedly connected to two symmetrically distributed positioning plates 8, each of which has a positioning hole 9.

[0028] By adopting the above technical solution, the positioning plate 8 and the positioning hole 9 cooperate to facilitate the connection between the annular seat 3 and the wall 1.

[0029] A sealing groove 10 is provided on the side of the annular seat 3 near the pre-embedded pipe 2. A sealing ring 11 is provided inside the sealing groove 10. One end of the pre-embedded pipe 2 is movably inserted into the sealing groove 10 and abuts against the sealing ring 11.

[0030] By adopting the above technical solution and setting the sealing ring 11, the sealing performance between the embedded pipe 2 and the annular seat 3 can be enhanced.

[0031] Working principle: When fireproofing the cable, the ring seat 3 is placed on the outside of one end of the pre-embedded pipe 2, and at the same time, one end of the pre-embedded pipe 2 is inserted into the interior of the sealing groove 10 and tightly abuts against the sealing ring 11. Then, the ring seat 3 is fixed to the wall 1 through the cooperation between the positioning plate 8 and the positioning hole 9. Then, one end of the cable is inserted into the interior of the ring seat 3.

[0032] Since there is a gap between the outer side of the cable and the annular seat 3, the threaded rod 79 is rotated, which simultaneously drives the moving block 710 to move along the outer side of the threaded rod 79 and drives the turntable 71 connected to the moving block 710 to rotate. The guide groove 72 guides the guide post 75, and at the same time drives multiple guide posts 75 to move away from or closer to the center of the annular seat 3. The telescopic rod 74 moves synchronously along the inside of the fixed frame 73, thereby pushing multiple arc plates 76 to move away from or closer to the rubber ring 5. When the cable pipe is inserted into the annular seat 3, the arc plates 76 are moved to one side of the rubber ring 5, causing the rubber ring 5 to deform and come into close contact with the outer side of the cable, thereby sealing the gap between the cable and the annular seat 3.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
