Description

Technical Field

[0001] This application relates to the field of cable conduit sealing technology, and in particular to a wound and extrusion adhesive injection sealing structure for cable conduits passing through external walls. Background Technology

[0002] As building heights increase and electrical equipment becomes more densely packed, the requirements for fire resistance, moisture resistance, and corrosion resistance in building electrical engineering are constantly rising. Poor sealing of cable conduits through walls can lead to problems such as fire spread, moisture intrusion, and electromagnetic interference, affecting the safe and stable operation of electrical systems. A good seal not only effectively isolates fire sources and prevents the spread of fire between different areas, but also prevents moisture and corrosion, extending the service life of cables. Simultaneously, it shields against electromagnetic interference, ensuring the quality of electrical signal transmission. Therefore, the sealing of cable conduits through walls has become crucial to ensuring the safety and functionality of buildings.

[0003] The traditional sealing materials commonly used in the industry, such as rubber sealing rings, fireproof putty, or foam, each have limitations in their sealing structure and principle. Rubber sealing rings consist of an annular ring body, a flange, and bolts, and rely on elastic compression for sealing.

[0004] However, traditional sealing materials such as rubber sealing rings, fireproof putty, or foam are prone to aging, cracking, or falling off during long-term use, resulting in a decline in sealing performance. In addition, existing technologies are difficult to adapt to the matching requirements of cables and conduits of different diameters, resulting in low construction efficiency and failing to meet high standards of waterproofing and fireproofing. Therefore, a cable conduit wrapping and extrusion-type glue injection sealing structure for external walls is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an external wall cable conduit winding and extrusion-type glue injection sealing structure, which aims to improve the problem of the lack of matching sealing structures that can adapt to cables and conduits of different diameters.

[0006] The technical solution provided in this application for a cable conduit wrapping and extrusion-type glue injection sealing structure for exterior walls adopts the following:

[0007] An external wall cable conduit winding and extrusion-type glue injection sealing structure includes an external wall conduit, a sealing mechanism inside the external wall conduit, a cable inside the external wall conduit, a guiding mechanism outside the sealing mechanism, the sealing mechanism including a fixing ring, the fixing ring being slidably connected to the inner wall of the external wall conduit, a winding tape inside the external wall conduit, a sealing ring fixedly connected to the rear end of the fixing ring, a connecting block fixedly connected to the end of the fixing ring away from the sealing ring, an inner column fixedly connected to the outside of the connecting block, and a control component outside the external wall conduit.

[0008] By adopting the above technical solution, the sealing mechanism achieves efficient sealing of the cable and the outer wall bushing through the coordinated operation of various components. The fixing ring can slide along the inner wall of the outer wall bushing, driving the winding tape and sealing ring to move. The winding tape slides along the threaded groove and gradually tightens with the help of friction with the cable. It works in conjunction with the sealing ring to squeeze and fill the gap, effectively isolating external moisture and dust, preventing their intrusion, providing a stable operating environment for the cable, and ensuring safe and reliable power transmission.

[0009] Preferably, the control component includes a threaded ring, the inner side of which is threadedly connected to the outside of the outer wall sleeve, and a plurality of outer columns are slidably connected to the outside of the threaded ring.

[0010] By adopting the above technical solution, the threaded ring in the control component is threaded with the outer wall sleeve. When the threaded ring is rotated, the outer column can be precisely controlled to slide along its radial direction. This structural design can convert rotational motion into precise linear displacement, thereby providing a stable and controllable driving force for the sealing mechanism, ensuring precise movement of the sealing components, and achieving flexible adjustment and reliable guarantee of the sealing effect.

[0011] Preferably, the outer part of the inner column is slidably connected to the inside of the outer column, and the outer part of the winding tape is in contact with the outer part of the cable.

[0012] By adopting the above technical solution, the sliding fit between the inner column and the outer column can stably transmit the power of the control component to the sealing mechanism. When the outer column moves, the inner column slides accordingly, driving the fixed ring and the winding tape to move. The friction generated by the winding tape contacting the cable causes it to slide along the thread groove and gradually squeeze, achieving a preliminary seal on the gap between the cable and the sleeve, effectively preventing foreign objects from entering and improving the reliability of the seal.

[0013] Preferably, the outer side of the sealing ring is in contact with the outer side of the cable, and the outer sides of the plurality of outer posts are arranged in an array on the outer side of the threaded ring.

[0014] By adopting the above technical solution, multiple outer columns are evenly distributed outside the threaded ring to ensure uniform force application, drive the inner column to move smoothly, and then drive the sealing ring to slide tightly along the cable. The sealing ring, with its elastic deformation, tightly fits the cable and the sleeve, providing secondary reinforcement and sealing to the gap after glue injection. This double protection effectively avoids sealing failure, significantly enhances the overall sealing performance, and extends the service life of the cable.

[0015] Preferably, the guiding mechanism includes a fixed box, the fixed box is fixedly connected to the front end of the outer column, a sliding block is slidably connected inside the fixed box, a guide wheel is rotatably connected to the bottom end of the sliding block, a telescopic column is fixedly connected to the top end of the sliding block, and a spring is sleeved on the outside of the telescopic column.

[0016] By adopting the above technical solution, the guiding mechanism uses a fixed box as a carrier. When the cable is inserted, the guide wheel contacts the cable and is compressed, which pushes the sliding block to compress the spring. The elastic reaction force of the spring makes the guide wheel adaptively fit the cable. No matter how the cable diameter changes, it can guide the cable to be accurately centered and inserted into the outer wall sleeve, avoiding deviation, creating good conditions for subsequent sealing operations, and improving sealing accuracy and effect.

[0017] Preferably, the top end of the telescopic column is fixedly connected to the inside of the fixed box, and the outside of the guide wheel is in contact with the outside of the cable.

[0018] By adopting the above technical solution, the telescopic column and the spring work together to give the guide wheel elastic adjustment capability. During the cable insertion process, the pressure generated by the contact between the guide wheel and the cable is transmitted to the telescopic column and the spring through the sliding block. The spring is compressed or rebounded, which drives the guide wheel to move up and down, always maintaining close contact with the cable and ensuring that the cable is inserted along the central axis of the sleeve, effectively improving installation efficiency and sealing reliability.

[0019] Preferably, one end of the spring is fixedly connected to the inside of the fixed box, and the other end of the spring is fixedly connected to the top of the sliding block.

[0020] By adopting the above technical solution, the spring, as the core elastic element of the guiding mechanism, drives the sliding block to adaptively adjust the position of the guide wheel through the elastic force generated by compression and rebound when the cable is inserted. This elastic adaptive mechanism can accurately adapt to cables of different diameters, ensuring that the guide wheel always fits the cable surface, guaranteeing accurate cable insertion, avoiding poor sealing caused by insertion deviation, and providing an important guarantee for the overall sealing effect.

[0021] Preferably, the inner wall of the outer wall sleeve is provided with a threaded groove, and the outer side of the winding tape is slidably connected to the inside of the threaded groove.

[0022] By adopting the above technical solution, the threaded groove on the inner wall of the outer wall sleeve and the wrapping tape are the key to achieving the initial seal. The threaded groove adopts a gradient design. When the wrapping tape slides along the groove under the action of cable friction, as the diameter of the threaded groove gradually decreases, the wrapping tape will be squeezed tightly against the cable and the inner wall of the sleeve, forming a reliable sealing barrier, effectively preventing the entry of external substances, and laying a solid foundation for subsequent glue injection and secondary sealing.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, after the cable is inserted, rotating the cable or sleeve causes the winding tape to slide along the gradually changing thread groove on the inner wall of the sleeve under the action of friction. As the diameter of the thread groove decreases, the winding tape gradually squeezes the cable and the inner wall of the sleeve to complete the initial seal. After the glue is injected to fill the external gap, rotating the threaded ring drives the inner and outer columns to move together, pushing the sealing ring to slide and tighten along the gradual structure of the sleeve to achieve a secondary seal. This extrusion-type glue injection structure provides double sealing protection, effectively copes with cables of different diameters, ensures no dead corners in the seal, prevents moisture and dust from entering, and provides reliable protection for the long-term stable operation of the cable.

[0025] 2. In this utility model, when the cable is inserted, the guide wheel contacts the cable surface and is pressed, which pushes the sliding block to compress the spring. The reverse elastic force generated by the spring makes the guide wheel fit tightly against the cable. This elastic adaptive mechanism can automatically adjust the position of the guide wheel. No matter how the cable diameter changes, it can guide the cable to remain in a centered position when inserted into the sleeve, avoiding sealing failure caused by offset. This creates ideal conditions for subsequent sealing and glue injection, and significantly improves the installation accuracy and sealing performance. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0033] Example: A sealing structure for cable conduit wrapping and extrusion with adhesive in an exterior wall, referring to... Figures 1 to 3The system includes an external wall sleeve 1, which is made of high-strength flame-retardant material. Its inner wall is finely processed and the threaded grooves are highly accurate, providing a reliable foundation for the installation and operation of subsequent sealing components. The external wall sleeve 1 is equipped with a sealing mechanism 2, which is the core component for achieving a tight seal between the cable and the sleeve. The external wall sleeve 1 is equipped with a cable 3, which is the carrier for power transmission. The sealing mechanism 2 is equipped with a guide mechanism 4 on the outside, which can assist the cable 3 in accurately inserting into the external wall sleeve 1 to ensure the sealing effect.

[0034] Specifically, in actual use, the guiding mechanism 4 can automatically and elastically adjust the cable 3 to precisely guide it to enter the outer wall sleeve 1 in the center, avoiding deviation. The sealing mechanism 2 achieves initial sealing through the cooperation of the winding tape 21 and the threaded groove, then fills the gap with glue, and finally completes secondary sealing with the sealing ring 22. The cooperation of each mechanism forms a reliable sealing system, effectively blocking water vapor and dust, and ensuring the long-term stable operation of the cable and the safety of power transmission.

[0035] The sealing mechanism 2 includes a fixing ring 23. The outer surface of the fixing ring 23 is machined with high precision, which can fit tightly against the inner wall of the outer wall sleeve 1 and achieve smooth sliding, ensuring its stability when moving inside the outer wall sleeve 1. The inner surface of the outer wall sleeve 1 is provided with a winding tape 21. The winding tape 21 is made of a material with excellent elasticity and wear resistance, which can maintain good performance under repeated friction and compression. The rear end of the fixing ring 23 is fixedly connected to a sealing ring 22. The sealing ring 22 is made of high temperature resistant and aging resistant rubber material, which has excellent sealing performance. The end of the fixing ring 23 away from the sealing ring 22 is fixedly connected to a connecting block 24. The connecting block 24 is used to connect the fixing ring 23 and the inner column 25 to ensure effective force transmission. The outer surface of the connecting block 24 is fixedly connected to the inner column 25. The outer surface of the outer wall sleeve 1 is provided with a control component 26.

[0036] Specifically, the sealing mechanism 2 and the control component 26 work together to achieve efficient sealing. After the cable 3 is inserted, the cable 3 or the outer wall sleeve 1 is rotated. Due to the friction between the cable 3 and the winding tape 21, it slides along the gradually changing thread groove on the inner wall of the outer wall sleeve 1. As the diameter of the thread groove gradually decreases, the winding tape 21 tightly squeezes the cable 3 and the inner wall of the sleeve, initially forming a seal. After the glue is injected, the threaded ring 261 is rotated. The outer column 262 drives the inner column 25 to move, pushing the fixing ring 23 and the sealing ring 22 to slide along the gradually changing structure inside the sleeve. The sealing ring 22 is further tightened to achieve a secondary seal, providing double protection for the glue injection effect and sealing quality.

[0037] The control component 26 can precisely adjust the position of the sealing component to achieve a tight seal. The control component 26 includes a threaded ring 261. The threaded connection design between the threaded ring 261 and the outer wall sleeve 1 ensures the accuracy and stability during rotation. Multiple outer posts 262 are slidably connected to the outside of the threaded ring 261. The outer posts 262 can convert the rotation of the threaded ring 261 into linear movement. The outer side of the inner post 25 is slidably connected to the inside of the outer post 262. Through the cooperation of the inner and outer posts 262, force transmission and displacement control are achieved. The outside of the winding tape 21 is in contact with the outside of the cable 3. The friction between the two is used to realize the movement of the winding tape 21. The outside of the sealing ring 22 is in contact with the outside of the cable 3. It plays a sealing role in subsequent movement. The outside of the multiple outer posts 262 are distributed in an array outside the threaded ring 261 to ensure uniform force transmission. The inner wall of the outer wall sleeve 1 is provided with a threaded groove. The gradual spiral design of the threaded groove is the key to achieving a tight fit of the winding tape 21. The outside of the winding tape 21 is slidably connected to the inside of the threaded groove. It can move along the threaded groove to achieve a seal.

[0038] Specifically, the control component 26 achieves precise control through a sophisticated mechanical structure. The threaded engagement between the threaded ring 261 and the outer wall sleeve 1 converts rotational motion into stable linear displacement. Multiple outer posts 262 are evenly distributed on the outside of the threaded ring 261 to ensure balanced force application. The sliding connection between the inner post 25 and the outer post 262 accurately transmits the displacement of the threaded ring 261 to the fixed ring 23, driving the sealing ring 22 to move. This achieves precise control of the position of the sealing components, ensuring the reliability and consistency of the sealing operation.

[0039] Reference Figure 1 , Figure 2 and Figure 4 The guiding mechanism 4 includes a fixed box 41, which is externally fixed to the front end of the outer column 262 by welding or bolts, providing stable support for the internal components. A sliding block 42 is slidably connected inside the fixed box 41, and the sliding block 42 can slide flexibly inside the fixed box 41. A guide wheel 43 is rotatably connected to the bottom end of the sliding block 42. The guide wheel 43 has a smooth surface, which can reduce friction with the cable 3. A telescopic column 44 is fixedly connected to the top end of the sliding block 42. The telescopic column 44 can extend and retract under pressure. A spring 45 is sleeved on the outside of the telescopic column 44, which provides elastic support for the guide wheel 43. The top end of the telescopic column 44 is fixedly connected to the inside of the fixed box 41 to ensure the stability of the movement of the telescopic column 44. The outside of the guide wheel 43 is in contact with the outside of the cable 3, which guides the cable 3 to be inserted. One end of the spring 45 is fixedly connected to the inside of the fixed box 41, and the other end is fixedly connected to the top end of the sliding block 42, so as to achieve adaptive adjustment through elastic force.

[0040] Specifically, the fixed box 41 provides a stable carrier for the internal components, the sliding block 42 slides freely inside the box, and the rotatable guide wheel 43 reduces the resistance to cable insertion. The telescopic column 44 and the spring 45 form an elastic unit. When the diameter of the cable 3 changes, the spring 45 is compressed or rebounded, which drives the guide wheel 43 to move up and down, always maintaining close contact with the cable 3, realizing precise guidance for cables 3 of different diameters, and ensuring that the cable 3 is accurately inserted into the center position of the outer wall sleeve 1.

[0041] Working principle: When the cable 3 needs to be connected and sealed with the outer wall sleeve 1, the outside of the cable 3 is inserted into the inside of the outer wall sleeve 1. At this time, the guide wheel 43 will contact the outside of the cable 3. After the guide wheel 43 is under pressure, it will push the sliding block 42 to slide inside the fixing box 41. At this time, the spring 45 will be compressed, thereby continuously pushing the sliding block 42 to slide in the opposite direction, so as to achieve the guiding effect of cables 3 of different diameters, so that the cable 3 is inserted into the inner wall sleeve 1 in a centered position, ensuring the effect of subsequent sealing and glue injection.

[0042] When the outer part of cable 3 is inserted into the outer wall sleeve 1, by rotating cable 3 or outer wall sleeve 1, the outer part of the spiral wrap 21 will slide within the threaded groove inside the outer wall sleeve 1 due to the friction between the cable 3 and the outer part of the spiral wrap 21. The threaded groove inside the outer wall sleeve 1 has a gradually decreasing spiral design, with its diameter gradually decreasing from the outside to the inside. This allows the spiral wrap 21 to gradually and tightly adhere to the outer part of cable 3 and the inner side of outer wall sleeve 1, achieving a sealing effect. At this point, the outer part of cable 3 and outer wall sleeve 1... There will be a gap on one side, which can be sealed and filled by injection. After the injection is completed, by rotating the threaded ring 261, the threaded ring 261 will drive the inner post 25 to move through the outer post 262, so that the fixing ring 23 and the sealing ring 22 can slide inside the outer wall sleeve 1. The gradient design inside the outer wall sleeve 1 allows the sealing ring 22 to seal the cable 3 and the outer wall sleeve 1 again, ensuring the effect of the injection. The extrusion-type injection sealing structure for cables 3 of different diameters can effectively ensure the sealing effect of the cable and the sleeve, ensuring the normal use of the cable.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
