Description

Technical Field

[0001] The utility model relates to the technical field of cable entry sealing, and more specifically, to a cable entry sealing structure. Background Art

[0002] Currently, when performing cable entry operations, first, a hole is opened in the wall, then a cable pipe is inserted into the hole and fixed, and then the cable is inserted into the cable pipe for entry. For the convenience of inserting the cable into the cable pipe, a cable pipe with a relatively large threading hole is selected. Then, there is a gap between the cable and the cable pipe after the cable enters the room. To prevent external moisture, dust and other substances from flowing into the room through the gap, a flexible seal is usually used to seal the cable pipe.

[0003] The working principle of the flexible seal is to put the flexible seal into the cable pipe, and then tighten the bolts of the connecting piece, forcing the flexible seal to deform. The inner circumferential surface of the flexible seal is closely attached to the cable surface, and the outer circumferential surface of the flexible seal is closely attached to the inner wall of the cable pipe. Then, a seal is formed inside and outside the cable pipe. This close contact forms an effective sealing layer between the inside and outside of the cable pipe, preventing the intrusion of external moisture, dust and other substances.

[0004] However, during actual use, the exposed parts of the bolts are exposed to the external environment. Especially in a humid or highly corrosive environment, these bolts are prone to rust. Rust will cause rust spots on the outer surface of the bolts, which will further affect their fastening function, making it difficult to disassemble the flexible seal when needed. The rusty bolts not only increase the labor intensity during the disassembly process, but also may damage the flexible seal or the cable pipe, further affecting the maintenance and use efficiency of the flexible seal. Summary of the Utility Model

[0005] The utility model provides a cable entry sealing structure, which solves the technical problem in the related art that when sealing a cable entry, the bolts on the flexible seal are easily rusted due to being exposed to the outside for a long time, which not only increases the labor intensity during the disassembly process, but also may damage the flexible seal or the cable pipe, further affecting the maintenance and use efficiency of the flexible seal.

[0006] The utility model provides a cable entry sealing structure, including a rubber part. A plurality of first extrusion blocks and a plurality of second extrusion blocks are respectively arranged at both ends of the rubber part. The first extrusion blocks and the second extrusion blocks are both arranged on the rubber part through a plurality of bolts. A groove is formed on the outer side of the second extrusion block. The cable entry sealing structure further includes:

[0007] A protective cover, which is arranged on the side of the second extrusion block away from the rubber part for safely protecting the bolts, and the bolts are located inside the protective cover;

[0008] A positioning mechanism is arranged in the groove and is used to position the protective cover on the second extrusion block. The positioning mechanism includes a slider arranged in the groove. A connecting block is arranged on one side of the slider away from the groove, and one end of the connecting block away from the slider is connected to the protective cover.

[0009] Furthermore, a cavity is formed inside the rubber part. The cavity divides the rubber part into a rubber outer ring and a rubber inner ring from outside to inside in sequence. The diameter of the rubber outer ring gradually increases from both ends to the middle, and the diameter of the rubber inner ring gradually decreases from both ends to the middle.

[0010] Furthermore, the bolt includes a screw rod and a nut. A plurality of round holes for the screw rod to pass through are formed on the first extrusion block, the second extrusion block and the rubber part, and the corresponding round holes are communicated with the cavity. The screw rod is arranged on the second extrusion block, and the screw rod sequentially passes through the round holes on the first extrusion block, the rubber part and the second extrusion block. A nut is screwed on the screw rod, and the nut is located inside the protective cover.

[0011] Furthermore, the positioning mechanism further includes a guide rod arranged in the groove, and the slider is slidably connected to the guide rod. Two symmetrically distributed mounting blocks are arranged on one side of the slider. The connecting block is rotatably arranged between the two mounting blocks. A spring is sleeved outside the guide rod, and two ends of the spring are respectively connected to one side of the slider and the inner wall of the groove.

[0012] Furthermore, an arc-shaped positioning port is formed on one side of the second extrusion block away from the rubber part, and one side of the protective cover is inserted into the arc-shaped positioning port.

[0013] Furthermore, a round hole for a cable to pass through is formed on the rubber part, and a cutting line is formed on the outside of the rubber part.

[0014] Furthermore, a notch is formed on one side of the protective cover away from the second extrusion block. A telescopic protection component is arranged on one side of the protective cover where the notch is located. The telescopic protection component includes a corrugated sleeve arranged on one side of the protective cover away from the second extrusion block, and a protection cover plate is arranged on one side of the corrugated sleeve away from the protective cover.

[0015] The beneficial effects of the present utility model are as follows:

[0016] By arranging the protective cover, the positioning mechanism and the telescopic protection component, after the cable is blocked when entering the house, the positioning mechanism can be used to make the protective cover tightly buckle on the second extrusion block, and then the cooperation of the telescopic protection component can be used to protect the bolt safely, so that the bolt will not be exposed during use, and thus it is not easy to rust during long-term use, and further the subsequent maintenance work of the rubber part is facilitated.

Detailed implementation manners

[0027] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0028] Embodiment 1

[0029] The present utility model discloses a cable inlet sealing structure. As Figures 1 - 7 shown, it includes a rubber part 1, a protective cover 6 and a positioning mechanism 7. A plurality of first extrusion blocks 2 and a plurality of second extrusion blocks 3 are respectively arranged at both ends of the rubber part 1. Both the first extrusion blocks 2 and the second extrusion blocks 3 are arranged on the rubber part 1 through a plurality of bolts 4. A groove 5 is formed on the outer side of the second extrusion block 3;

[0030] The protective cover 6 is arranged on the side of the second extrusion block 3 away from the rubber part 1 for safety protection of the bolts 4, and the bolts 4 are located inside the protective cover 6;

[0031] The positioning mechanism 7 is arranged in the groove 5 for positioning the protective cover 6 on the second extrusion block 3. The positioning mechanism 7 includes a slider 701 arranged in the groove 5. A connecting block 8 is arranged on the side of the slider 701 away from the groove 5, and one end of the connecting block 8 away from the slider 701 is connected to the protective cover 6.

[0032] Among them, a cavity 9 is formed inside the rubber part 1. The cavity 9 divides the rubber part 1 into a rubber outer ring 101 and a rubber inner ring 102 from outside to inside in sequence. The diameter of the rubber outer ring 101 gradually increases from both ends to the middle, and the diameter of the rubber inner ring 102 gradually decreases from both ends to the middle.

[0033] It should be noted that through the design of the diameter change of the rubber outer ring 101 and the rubber inner ring 102, the rubber part 1 can fit more closely on the cable pipe and the cable when subjected to external or internal pressure, reducing the possibility of leakage and greatly improving the sealing performance.

[0034] Among them, the bolt 4 includes a screw rod 401 and a nut 402. A plurality of round holes 10 for the screw rod 401 to pass through are formed on both the first extrusion block 2, the second extrusion block 3 and the rubber part 1, and the corresponding round holes 10 are communicated with the cavity 9. The screw rod 401 is arranged on the second extrusion block 3, and the screw rod 401 sequentially passes through the round holes 10 on the first extrusion block 2, the rubber part 1 and the second extrusion block 3. A nut 402 is screwed on the screw rod 401, and the nut 402 is located inside the protective cover 6.

[0035] It should be noted that when sealing the cable inlet, the staff uses tools to rotate a plurality of nuts 402. At this time, the first extrusion block 2 and the second extrusion block 3 approach each other, thereby squeezing the rubber part 1. Then the rubber outer ring 101 will expand and be in close contact with the inner wall of the cable pipe, and then the rubber inner ring 102 will deform and be in close contact with the outer side of the cable, and thus the cable inlet sealing can be completed.

[0036] Among them, the positioning mechanism 7 further includes a guide rod 702 disposed in the groove 5, and the slider 701 is slidably connected to the guide rod 702. Two symmetrically distributed mounting blocks 703 are provided on one side of the slider 701. The connecting block 8 is rotatably disposed between the two mounting blocks 703. A spring 704 is sleeved outside the guide rod 702, and the two ends of the spring 704 are respectively connected to one side of the slider 701 and the inner wall of the groove 5.

[0037] It should be noted that when blocking the cable from entering the house, the staff can first pull the protective cover 6 away from the second pressing block 3, and then directly rotate the protective cover 6 to expose the screw 401 and the nut 402, which facilitates the staff to rotate the nut 402 for the blocking work. After the cable entry blocking is completed, at this time, the staff can first pull the protective cover 6. The protective cover 6 drives the connecting block 8 to move, and the connecting block 8 drives the slider 701 to slide on the guide rod 702. The sliding of the slider 701 will squeeze the spring 704. Then the staff rotates the protective cover 6 to cover it on the second pressing block 3, and then releases the protective cover 6. At this time, the elastic force of the spring 704 is used to make the protective cover 6 tightly fastened on the second pressing block 3. Then the screw 401 and the nut 402 can be safely protected by the protective cover 6, so that the screw 401 and the nut 402 are not easily corroded during long-term use.

[0038] Among them, an arc-shaped positioning port 11 is opened on the side of the second pressing block 3 away from the rubber part 1, and one side of the protective cover 6 is inserted into the arc-shaped positioning port 11.

[0039] It should be noted that as described above, during the process of covering the protective cover 6 on the second pressing block 3, one side of the protective cover 6 is exactly inserted into the arc-shaped positioning port 11, which further ensures the stability of the protective cover 6 covering on the second pressing block 3.

[0040] Among them, a circular opening 12 for the cable to pass through is opened on the rubber part 1, and a cutting line 13 is opened on the outside of the rubber part 1.

[0041] It should be noted that when the staff places the rubber part 1 into the cable pipe, the staff can first use a cutting tool to cut the rubber part 1 along the cutting line 13, and then can put the cut rubber part 1 on the cable so that the cable passes through the circular opening 12, and then place the rubber part 1 along the cable into the cable pipe, and finally perform the blocking work for the cable to enter the house.

[0042] Embodiment 2

[0043] A cable entry blocking structure is disclosed in the present utility model, as Figures 8 - 9As shown in the figure, a notch 14 is formed on one side of the protective cover 6 away from the second extrusion block 3. A telescopic protection component 15 is arranged on one side of the protective cover 6 where the notch 14 is located. The telescopic protection component 15 includes a corrugated sleeve 1501 arranged on the side of the protective cover 6 away from the second extrusion block 3, and a protection cover plate 1502 is arranged on the side of the corrugated sleeve 1501 away from the protective cover 6.

[0044] It should be noted that when sealing the cable for entering the household, when there is a large difference in size between the rubber part 1 and the cable pipe, in order to ensure the sealing effect, the position of the nut 402 on the screw rod 401 needs to be adjusted. Due to the large size difference, the nut 402 needs to be turned a large number of turns to make the rubber part 1 reach a proper sealing state. During this process, the screw rod 401 will be exposed for a relatively long length. Then, the use position of the protection cover plate 1502 can be adjusted by using the corrugated sleeve 1501, so that the screw rod 401 and the nut 402 can be safely protected.

[0045] In summary, when the utility model is in use, first use a cutting knife to cut the rubber part 1 along the cutting line 13, and then the cut rubber part 1 can be sleeved on the cable. At this time, the cable passes through the round opening 12, and then the rubber part 1 is placed along the cable into the cable pipe. At this time, the staff can first pull the protective cover 6 to make it away from the second extrusion block 3, and then directly rotate the protective cover 6 to expose the screw rod 401 and the nut 402. Then, the staff can use tools to rotate the multiple nuts 402, so that the first extrusion block 2 and the second extrusion block 3 approach each other to squeeze the rubber part 1. Then, the outer rubber ring 101 will expand and be in close contact with the inner wall of the cable pipe, and then the inner rubber ring 102 will deform and be in close contact with the outer side of the cable, and then the household cable sealing can be completed.

[0046] When the household cable sealing is completed, the staff can first pull the protective cover 6. The protective cover 6 drives the connecting block 8 to move. The movement of the connecting block 8 drives the slider 701 to slide on the guide rod 702. The sliding of the slider 701 will squeeze the spring 704. Then, the staff rotates the protective cover 6 to cover it on the second extrusion block 3, and one side of the protective cover 6 is just inserted into the arc-shaped positioning opening 11. Then, release the protective cover 6. At this time, using the elastic force of the spring 704, the protective cover 6 can be tightly buckled on the second extrusion block 3. Then, the screw rod 401 and the nut 402 can be safely protected through the protective cover 6. At the same time, using the cooperation of the corrugated sleeve 1501 and the protection cover plate 1502, the screw rod 401 with a relatively long exposed length can be safely protected, so that the screw rod 401 and the nut 402 are not exposed outside, and the screw rod 401 and the nut 402 are not easy to rust during long-term use, and then the subsequent maintenance work of the rubber part 1 is facilitated.

[0047] The embodiments of the present utility model have been described above. However, these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of these embodiments, those of ordinary skill in the art can also make more equivalent embodiments in various forms, all of which fall within the protection scope of these embodiments.
