The sealing plate, the limiting blocks, the second compression springs and the second installation blocks are all located on both sides of the cable.

[0012] The present invention also provides a method of using the above-described structure for a cable to pass through a vibration isolation layer. The method includes the following steps:

[0013] Step 1: Pass one end of each of the two cables through the mounting opening and through the vibration isolation layer. Then, place galvanized iron sheets outside the adjacent ends of the two cables, and install and fix them with bolts. Install a fireproof canvas outside the galvanized iron sheets for fire isolation to prevent the cable connection from being affected by fire. Then, install a protective bonding conductor at one end of the two cables with bolts so that the two cables are connected for use. Install a sealing block at the bottom of the vibration isolation layer to seal the cable and the mounting opening. At the same time, install a first telescopic rod and the sealing block, and install a protective block outside the galvanized iron sheet, the fireproof canvas, and the protective bonding conductor to protect the connection ends of the two cables. Then, install a moving rod and a fixed rod between the vibration isolation layers to support and fix the cables between the vibration isolation layers;

[0014] Step 2: When the vibration isolation layer vibrates, the moving rod drives the moving block to move towards the first mounting block inside the fixed rod, causing the first compression spring to compress. At the same time, the connecting block moves, deflecting the rotating plate and pushing the moving plate towards the moving opening direction, so that the fixed rod passes through the moving opening and pushes the abutting plate towards one side of the protective block. The fixed spring compresses, causing the abutting plate to be on both sides of the protective block, buffering the force generated by the vibration isolation layer to prevent the cable from vibrating, and at the same time tightly fixing the protective block;

[0015] Step 3: When the moving rod moves towards the inside of the fixed rod, the second tooth on one side of the moving rod moves downward, causing the gear to drive the rotating rod to rotate along the support block. Due to the meshing of the gear and the second tooth, the second telescopic rod drives the limiting block to move along the inner wall of the fixed rod and move towards the outside of the fixed rod, thereby causing the second telescopic rod to contract and drive the pushing block to move. When the pushing block moves to fit with the bottom of the seal, the top of the second telescopic rod passes through the movable opening and moves to the bottom of the movable block, and pushes the movable plate towards the vibration isolation layer direction, compressing the connecting spring, thereby tightly fixing the fixed block so that the fixed block can fix the cable at the mounting opening inside the sealing block;

[0016] Step 4: When the movable block moves and drives the connecting spring to compress, the support rod on one side of the movable block drives the round convex through the through hole and moves into the inside of the fixed block, and moves along the inclined surface on one side of the sealing plate. When the round convex moves, it squeezes the sealing plate, causing the sealing plate to drive the limiting block to move towards both sides of the cable, compressing the second compression spring, so that one end of the sealing plate fits with both sides of the cable, and the sealing plate keeps the cable at the mounting opening sealed, facilitating the installation and use of the cable.

[0017] The beneficial effects of the present invention are:

[0018] (1) The present invention supports and fixes the vibration isolation layer through the moving rod and the fixed rod, which can buffer the vibration generated by the vibration isolation layer. At the same time, it can drive the pressing plate to move to fix the protection, prevent the cable from vibrating, prevent the cable connection end from being damaged, prevent the staircase from generating a vibration path during the installation and use of the cable, improve the stability of the cable installation, and facilitate the use of the cable.

[0019] (2) When the present invention buffers the vibration generated by the vibration isolation layer by moving the moving rod, through the action of the gear, the first tooth, and the second rack, the second telescopic rod moves and drives the pushing block to move, so that the sealing block is tightly fixed. When buffering the vibration received by the vibration isolation layer and supporting and fixing the cable, the sealing plate can be moved to the installation opening to maintain the seal, further improving the sealing performance when the cable is installed with the vibration isolation layer and extending the service life of the cable.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a structure for a cable to pass through a vibration isolation layer, as Figures 1 to 4 shown, including two vibration isolation layers 1. Installation openings are provided on both of the two vibration isolation layers 1. Cables 2 are arranged inside the installation openings. Galvanized iron sheets 3 are arranged on the outer sides of the adjacent ends of the cables 2. The galvanized iron sheets 3 are fixedly installed at one end of the cables 2 through bolts. Fireproof canvases 4 are arranged on the outer sides of the galvanized iron sheets 3. Protective bonding conductors 5 are arranged on both the upper and lower sides of the galvanized iron sheets 3. Both ends of the protective bonding conductors 5 are installed on the cables 2 through bolts. Protection blocks 6 are arranged on the outer sides of the protective bonding conductors 5 and the galvanized iron sheets 3. First telescopic rods 7 are arranged on both the upper and lower sides of the protection blocks 6. Sealing blocks 8 are fixedly installed at one end of the first telescopic rods 7. The sides of the sealing blocks 8 away from the first telescopic rods 7 are fixedly installed with one side of the vibration isolation layer 1. Fixed rods 9 are arranged on both sides of the protection blocks 6. Moving rods 10 are arranged on both the upper and lower sides of the fixed rods 9. Moving blocks 11 are fixedly installed at one end of the moving rods 10. One side of the moving blocks 11 is slidably connected to the inner wall of the fixed rods 9, and the other side thereof is fixedly installed with connecting blocks 12. First compression springs 13 are fixedly connected to the sides of the moving blocks 11 away from the moving rods 10. First mounting blocks 14 are fixedly installed at one end of the first compression springs 13. One side of the first mounting blocks 14 is fixedly installed with the inner wall of the fixed rods 9. Rotating plates 15 are hinged to one side of the connecting blocks 12. Moving plates 16 are hinged to one end of the rotating plates 15. Connecting rods 17 are fixedly installed on one side of the moving plates 16. Tightening plates 18 are fixedly installed at one end of the connecting rods 17. Fixed springs 19 are fixedly installed on one side of the tightening plates 18. One end of the fixed springs 19 is fixedly installed with one side of the protection blocks 6. Fixing structures 20 are arranged on the sides of the moving rods 10 close to the protection blocks 6.

[0030] The cable 2 can be easily laid through the installation port across the vibration isolation layer 1. By installing the galvanized iron sheet 3 at one end of the two cables 2 with bolts, it can prevent the corrosion of the cable 2 and electromagnetic interference, and is convenient for protecting the cable 2. Then, by installing the fireproof canvas 4 on the outside of the galvanized iron sheet 3, the fireproof canvas 4 has strong puncture resistance and can prevent the galvanized iron sheet 3 from being easily punctured by sharp objects, thus protecting the cable 2 from external physical damage. Then, the protective connecting conductor 5 is connected to the two cables 2 with bolts, so as to facilitate the connection and use of the two cables 2. Then, the sealing block 8 is installed at the bottom of the vibration isolation layer 1 to seal the cable 2 and the installation port. The movable rod 10 and the fixed rod 9 are installed between the vibration isolation layers 1 to support and fix the cable 2 between the vibration isolation layers 1. When the vibration isolation layer 1 vibrates, the first telescopic rod 7 contracts to buffer the force received by the vibration isolation layer 1 and prevent the protective block 6 from being damaged. At the same time, the movable rod 10 drives the movable block 11 to move towards the first installation block 14 inside the fixed rod 9, causing the first compression spring 13 to compress. At the same time, the connecting block 12 moves, deflecting the rotating plate 15 to push the movable plate 16 towards the moving port, causing the fixed rod 9 to pass through the moving port and push the abutting plate 18 towards one side of the protective block 6. And by compressing the fixed spring 19, the abutting plate 18 is on both sides of the protective block 6 to buffer the force generated by the vibration isolation layer 1, prevent the cable 2 from vibrating, and at the same time tightly fix the protective block 6. When the movable rod 10 moves, the fixed structure 20 moves towards the sealing block 8, causing the sealing block 8 to be tightly fixed, buffering the vibration received by the vibration isolation layer 1, supporting and fixing the cable 2, improving the sealing performance when the cable 2 is installed on the vibration isolation layer 1, and prolonging the service life of the cable 2.

[0031] As Figures 1 to 3 shown, the first telescopic rods 7 are located on both sides of the cable 2 and are symmetrically arranged with the center of the protective block 6. A fixed block 21 is arranged at the top end inside the sealing block 8. Both sides of the fixed block 21 are slidably connected to the inner wall of the sealing block 8. Both sides of the bottom of the fixed block 21 are fixedly installed with connecting springs 22. One end of each connecting spring 22 is fixedly installed with a movable block 23. A sealing structure is arranged inside the fixed block 21. One end of the cable 2 penetrates through the sealing block 8 and the middle of the fixed block 21.

[0032] The first telescopic rods 7 facilitate the installation of the protective block 6 on the outside of the sealing block 8, the galvanized iron sheet 3, the fireproof canvas 4 and the protective connecting conductor 5 to protect the connection ends of the two cables 2. And the first telescopic rods 7 can buffer the vibration generated by the vibration isolation layer 1 to prevent the protective block 6 from being damaged. When the movable rod 10 moves towards the inside of the fixed rod 9, the fixed structure 20 can cause the movable block 23 to move towards the vibration isolation layer 1 and compress the connecting spring 22, pushing the fixed block 21 to tightly abut the installation port, and making the sealing structure tightly abut the cable 2 at the installation port, so that the cable 2 and the vibration isolation layer 1 are kept sealed, improving the connection stability between the cable 2 and the vibration isolation layer 1.

[0033] As Figure 3 、 Figure 5 shown, the connecting spring 22 and the movable block 23 are located on both sides of the cable 2. Both ends of the bottom of the sealing block 8 are provided with movable openings. The fixing structure 20 is located at the bottom of the movable openings. The movable block 23 is arranged corresponding to the movable openings, and the side of it away from the connecting spring 22 is attached to the inner wall of the sealing block 8.

[0034] Through the movable opening, it is convenient for one end of the fixing structure 20 to move into the sealing block 8, push the movable block 23 to move and separate from the inner wall of the bottom of the sealing block 8, and the connecting spring 22 is compressed. As a result, the fixing block 21 moves upward and presses tightly against the sealing block 8 inside the sealing block 8, improving the stability of the connection between the sealing block 8 and the cable 2 and the vibration isolation layer 1.

[0035] As Figures 3 to 4 shown, the rotating plate 15 and the moving plate 16 are located on one side of the moving block 11 and the connecting spring 22. One end of the connecting rod 17 and on one side of the fixed rod 9 is provided with a moving opening. One end of the connecting rod 17 away from the rotating plate 15 is located at the moving opening. The pressing plate 18 is arranged corresponding to the moving opening, and it is located between the fixed rod 9 and the protection block 6. There are two fixing springs 19, and they are located on the upper and lower sides of the pressing plate 18.

[0036] When the moving rod 10 drives the moving block 11 and the connecting block 12 to move, the rotating plate 15 deflects, thereby pushing the moving plate 16 and the fixed rod 9 to move in the direction of the moving opening. When the moving plate 16 moves to the moving opening, the fixed rod 9 passes through the moving opening and moves to one side of the fixed rod 9, and the pressing plate 18 separates from one side of the fixed rod 9 and moves to one side of the protection block 6, and squeezes the connecting spring 22. Thus, it can buffer the force received by the moving rod 10 from the vibration isolation layer 1, and can make the pressing plate 18 and the connecting spring 22 press tightly against the protection block 6, improving the service life of the protection block 6, further improving the stability of the connection end of the cable 2, and facilitating the protection of the connection end of the cable 2.

[0037] As Figures 4 to 6 shown, the fixing structure 20 includes a second telescopic rod 201. A limiting block 202 is fixedly installed at the bottom of the second telescopic rod 201. One side of the limiting block 202 is slidably connected to the inner wall of the fixed rod 9. A pushing block 203 is fixedly installed at the top of the fixed end of the second telescopic rod 201. A first tooth 204 is provided on one side of the bottom end of the second telescopic rod 201. A second tooth 205 is provided on the side of the moving rod 10 corresponding to the first tooth 204. A gear 206 is meshed with one side of the first tooth 204. A rotating rod 207 is fixedly installed in the middle of the gear 206. One side of the gear 206 is meshed with the second tooth 205.

[0038] When the moving rod 10 drives the second tooth 205 to move inside the fixed rod 9, the gear 206 drives the rotating rod 207 to rotate. Through the engagement of the first tooth 204 and the gear 206, the second telescopic rod 201 drives the limiting block 202 to move upward along the inner wall of the fixed rod 9, causing the second telescopic rod 201 to contract and the pushing block 203 to move towards the sealing block 8. When the pushing block 203 moves to the bottom of the sealing block 8 and fits with the bottom of the sealing block 8, the limiting block 202 moves to the inner wall at the top of the fixed rod 9. At the same time, the end of the second telescopic rod 201 away from the limiting block 202 moves into the sealing block 8 through the movable opening and pushes the movable block 23 to move away from the movable opening, compressing the connecting spring 22. The movable block 23 moves away from the inner wall of the sealing block 8, and under the action of the connecting spring 22, the fixed block 21 is pushed to tightly press against the sealing block 8 inside the sealing block 8, improving the stability and sealing performance of the installation of the sealing block 8 for the cable 2 and the vibration isolation layer 1.

[0039] As Figures 5 to 6 shown, the bottom end of the second telescopic rod 201 is located inside the fixed rod 9, and the other end passes through the top of the moving rod 10 and extends to the bottom of the sealing block 8 corresponding to the movable opening. The limiting block 202 is located on one side of the rotating plate 15, the gear 206 is located on the side of the connecting block 12 away from the rotating plate 15, and both ends of the rotating rod 207 are rotatably connected to the support blocks, and one side of the support blocks is fixedly installed on the inner wall of the fixed rod 9.

[0040] Since the bottom end of the second telescopic rod 201 is located inside the fixed rod 9, the moving rod 10 can drive the second tooth 205 to move, causing the gear 206 to drive the rotating rod 207 to rotate along the support blocks. Through the fixed installation of the support blocks on the inner wall of the fixed rod 9, the stability of the rotation of the gear 206 and the rotating rod 207 is improved, and under the action of the second tooth 205, the second telescopic rod 201 drives the limiting block 202 to move upward along the inner wall of the fixed rod 9, enabling one end of the second telescopic rod 201 to move inside the sealing block 8, causing the fixed block 21 to tightly press against the sealing block 8, further improving the sealing performance of the sealing block 8.

[0041] As Figures 6 to 7 shown, the sealing structure includes a sealing plate 24. Limiting blocks 25 are fixedly installed on both sides of the sealing plate 24. A second compression spring 26 is fixedly installed on one side of the limiting block 25. One end of the second compression spring 26 is fixedly installed with a second installation block 27, and one side of the second installation block 27 is fixedly installed on the inner wall of the fixed block 21. The side of the sealing plate 24 close to the limiting block 25 is an inclined surface. A through hole is opened at the bottom of the inclined surface and at the bottom of the fixed block 21. A circular convex 28 is provided at the bottom of the through hole. A support rod 29 is fixedly installed at the bottom of the circular convex 28, and the bottom of the support rod 29 is fixedly installed with the top of the movable block 23.

[0042] When one end of the second telescopic rod 201 pushes the movable block 23 to move and drives the connecting spring 22 to compress, the support rod 29 on one side of the movable block 23 drives the circular protrusion 28 to move through the through hole into the inside of the fixed block 21 and move along the inclined surface on one side of the sealing plate 24. When the circular protrusion 28 moves, it squeezes the sealing plate 24, causing the sealing plate 24 to drive the limiting block 25 to move towards both sides of the cable 2, and the second compression spring 26 compresses, so that one end of the sealing plate 24 fits against both sides of the cable 2, enabling the sealing plate 24 to seal the cable 2 at the installation opening, further improving the sealing performance between the cable 2 and the installation opening, and facilitating the installation of the cable 2.

[0043] As Figures 6 to 7 shown, the through hole is arranged corresponding to the movable opening. The connecting spring 22 is located outside the circular protrusion 28 and the support rod 29. The bottom of the sealing plate 24 is slidably connected to the inner wall of the fixed block 21. The sealing plate 24, the limiting block 25, the second compression spring 26 and the second mounting block 27 are all located on both sides of the cable 2.

[0044] By arranging the through hole corresponding to the movable opening, the second telescopic rod 201 can move through the movable opening into the inside of the fixed block 21, squeeze the movable block 23, so that the support rod 29 and the circular protrusion 28 on one side of the movable block 23 move through the through hole into the inside of the fixed block 21. The movement of the circular protrusion 28 facilitates the movement of the sealing plate 24, enabling the sealing plate 24 to move along the inner wall of the fixed block 21, driving the limiting blocks 25 on both sides of the sealing plate 24 to move, and the connecting spring 22 to stretch, so that the sealing plate 24 can move to the installation opening and fit against the outer side of the cable 2, improving the sealing performance of the cable 2 inside the fixed block 21, and thus facilitating the use of the cable 2.

[0045] The present invention also provides a method of using the above structure for the cable 2 to pass through the vibration isolation layer 1. The method includes the following steps:

[0046] Step 1: Pass one end of each of the two cables 2 through the installation opening and through the vibration isolation layer 1. Then place the galvanized iron sheet 3 outside the closer ends of the two cables 2 and install and fix it with bolts. Install the fireproof canvas 4 outside the galvanized iron sheet 3 for fire isolation to prevent the connection part of the cable 2 from being affected by fire. Then install the protective bonding conductor 5 at one end of the two cables 2 with bolts to connect and use the two cables 2. Install the sealing block 8 at the bottom of the vibration isolation layer 1 to seal the cable 2 and the installation opening. At the same time, install the first telescopic rod 7 and the sealing block 8, and install the protective block 6 outside the galvanized iron sheet 3, the fireproof canvas 4 and the protective bonding conductor 5 to protect the connection ends of the two cables 2. Then install the moving rod 10 and the fixed rod 9 between the vibration isolation layers 1 to support and fix the cable 2 between the vibration isolation layers 1.

[0047] Step 2: When the vibration isolation layer 1 vibrates, the moving rod 10 drives the moving block 11 to move towards the first mounting block 14 inside the fixed rod 9, causing the first compression spring 13 to compress. At the same time, the connecting block 12 moves, deflecting the rotating plate 15 and pushing the moving plate 16 towards the moving port. The fixed rod 9 passes through the moving port and pushes the pressing plate 18 towards one side of the protection block 6, and through the compression of the fixed spring 19, the pressing plate 18 is on both sides of the protection block 6 to buffer the force generated by the vibration isolation layer 1, prevent the cable 2 from vibrating, and at the same time tightly fix the protection block 6;

[0048] Step 3: When the moving rod 10 moves towards the inside of the fixed rod 9, the second tooth 205 on one side of the moving rod 10 moves downward, causing the gear 206 to drive the rotating rod 207 to rotate along the support block. Through the meshing of the gear 206 and the first tooth 204, the second telescopic rod 201 drives the limiting block 202 to move along the inner wall of the fixed rod 9 and move towards the outside of the fixed rod 9. Thus, the second telescopic rod 201 contracts, driving the pushing block 203 to move. When the pushing block 203 moves to fit with the bottom of the sealing block 8, the top of the second telescopic rod 201 passes through the moving port and moves to the bottom of the moving block 23, and pushes the moving plate towards the vibration isolation layer 1, compressing the connecting spring 22, thereby tightly fixing the fixing block 21, enabling the fixing block 21 to fix the cable 2 at the installation port inside the sealing block 8;

[0049] Step 4: When the moving block 23 moves and drives the connecting spring 22 to compress, the support rod 29 on one side of the moving block 23 drives the round convex 28 to move through the through hole into the inside of the fixing block 21 and move along the inclined surface on one side of the sealing plate 24. When the round convex 28 moves, it squeezes the sealing plate 24, causing the sealing plate 24 to drive the limiting block 25 to move towards both sides of the cable 2, compressing the second compression spring 26, so that one end of the sealing plate 24 fits with both sides of the cable 2, enabling the sealing plate 24 to keep the cable 2 at the installation port sealed, facilitating the installation and use of the cable 2.

[0050] Working principle: When in use, one end of each of the two cables 2 passes through the installation opening and penetrates the vibration isolation layer 1 respectively. Then, the galvanized iron sheet 3 is placed outside the closer ends of the two cables 2 and is installed and fixed with bolts. A fireproof canvas 4 is installed outside the galvanized iron sheet 3 for fire isolation to prevent the connection of the cables 2 from being affected by fire. Then, the protective bonding conductor 5 is installed at one end of the two cables 2 with bolts so that the two cables 2 are connected for use. The sealing block 8 is installed at the bottom of the vibration isolation layer 1 to seal the cables 2 and the installation opening. At the same time, through the installation of the telescopic rod and the sealing block 8, the protective block 6 is installed outside the galvanized iron sheet 3, the fireproof canvas 4 and the protective bonding conductor 5 to protect the connection ends of the two cables 2. Then, the moving rod 10 and the fixed rod 9 are installed between the vibration isolation layers 1 to support and fix the cables 2 between the vibration isolation layers 1. When the vibration isolation layer 1 vibrates, the first telescopic rod 7 contracts to buffer the force received by the vibration isolation layer 1 and prevent the protective block 6 from being damaged. At the same time, the moving rod 10 drives the moving block 11 to move towards the first installation block 14 inside the fixed rod 9, causing the first compression spring 13 to compress. At the same time, the connecting block 12 moves, deflecting the rotating plate 15 to push the moving plate 16 towards the moving port, causing the fixed rod 9 to pass through the moving port and push the pressing plate 18 towards one side of the protective block 6. The compression of the fixed spring 19 causes the pressing plate 18 to be on both sides of the protective block 6 to buffer the force generated by the vibration isolation layer 1, prevent the cables 2 from vibrating, and at the same time tightly fix the protective block 6. Buffer the vibration received by the vibration isolation layer 1, support and fix the cables 2, and improve the sealing performance when the cables 2 and the vibration isolation layer 1 are installed. When the moving rod 10 moves inside the fixed rod 9, the second tooth 205 on one side of the moving rod 10 moves downward, causing the gear 206 to drive the rotating rod 207 to rotate along the support block. Through the meshing of the gear 206 and the first tooth 204, the second telescopic rod 201 drives the limiting block 202 to move along the inner wall of the fixed rod 9 and move towards the outside of the fixed rod 9, so that the second telescopic rod 201 contracts, driving the pushing block 203 to move. When the pushing block 203 moves to the bottom of the sealing block 8 and fits with it, the top of the second telescopic rod 201 passes through the movable port and moves to the bottom of the movable block 23, and pushes the movable block 23 towards the vibration isolation layer 1, compressing the connecting spring 22, thereby tightly fixing the fixing block 21 so that the fixing block 21 can fix the cables 2 at the installation opening inside the sealing block 8.

[0051] When the moving of the movable block 23 drives the connecting spring 22 to be compressed, the support rod 29 on one side of the movable block 23 drives the round convex 28 to move through the through hole into the interior of the fixed block 21 and move along the inclined surface on one side of the sealing plate 24. When the round convex 28 moves, it presses the sealing plate 24, causing the sealing plate 24 to drive the limiting block 25 to move to both sides of the cable 2, and the second compression spring 26 is compressed, so that one end of the sealing plate 24 fits with both sides of the cable 2, making the sealing plate 24 keep the cable 2 at the installation opening sealed, which is convenient for the installation and use of the cable 2. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.

Then, place the galvanized iron sheet (3) outside the adjacent ends of the two cables (2), and install and fix it with bolts. Install the fireproof canvas (4) outside the galvanized iron sheet (3) for fire isolation to prevent the connection of the cables (2) from being affected by fire. Then, install the protective bonding conductor (5) at one end of the two cables (2) with bolts to connect the two cables (2) for use. Install the sealing block (8) at the bottom of the vibration isolation layer (1) to seal the cables (2) and the mounting opening. At the same time, install the first telescopic rod (7) and the sealing block (8), and install the protective block (6) outside the galvanized iron sheet (3), the fireproof canvas (4), and the protective bonding conductor (5) to protect the connection ends of the two cables (2). Then, install the moving rod (10) and the fixed rod (9) between the vibration isolation layers (1) to support and fix the cables (2) between the vibration isolation layers (1). Step 2: When the vibration isolation layer (1) vibrates, the moving rod (10) drives the moving block (11) to move towards the first mounting block (14) inside the fixed rod (9), compressing the first compression spring (13). At the same time, the connecting block (12) moves, deflecting the rotating plate (15) to push the moving plate (16) towards the moving opening, causing the fixed rod (9) to pass through the moving opening and push the abutting plate (18) towards one side of the protective block (6).

Step 3: When the moving rod (10) moves inside the fixed rod (9), the second tooth (205) on one side of the moving rod (10) moves downward, causing the gear (206) to drive the rotating rod (207) to rotate along the support block. Due to the meshing of the gear (206) and the second tooth (205), the second telescopic rod (201) drives the limiting block (202) to move along the inner wall of the fixed rod (9) and move towards the outside of the fixed rod (9), causing the second telescopic rod (201) to contract and drive the pushing block (203) to move. When the pushing block (203) moves to fit the bottom of the seal, the top of the second telescopic rod (201) passes through the movable opening and moves to the bottom of the movable block (23), and pushes the movable plate towards the vibration isolation layer (1), compressing the connecting spring (22), thereby tightly fixing the fixed block (21), enabling the fixed block (21) to fix the cable (2) at the mounting opening inside the sealing block (8). Step 4: When the movable block (23) moves to drive the connecting spring (22) to compress, the support rod (29) on one side of the movable block (23) drives the circular protrusion (28) to move through the through hole into the interior of the fixed block (21), and move along the inclined surface on one side of the sealing plate (24). When the circular protrusion (28) moves, it squeezes the sealing plate (24), causing the sealing plate (24) to drive the limiting block (25) to move towards both sides of the cable (2), and the second compression spring (26) compresses, so that one end of the sealing plate (24) fits against both sides of the cable (2), enabling the sealing plate (24) to maintain the seal of the cable (2) at the installation opening, facilitating the installation and use of the cable (2).
