Technical Field
[0001] This utility model relates to the field of line protection device technology, and in particular to an assembled cable outlet cover. Background Technology
[0002] In today's context of increasingly complex electrical equipment and denser wiring layouts, prefabricated cable trays, as key components ensuring the safety and neatness of wiring, have attracted much attention for their technological innovation. Whether it's high-voltage distribution cabinets in large industrial plants, distribution boxes in city streets and alleys, or intelligent electrical systems in modern buildings, cable trays bear the heavy responsibility of protecting cables, preventing leakage, and providing dust and water protection. Their performance directly affects the stable operation of the entire electrical system.
[0003] Traditional modular cable trays typically employ simple and direct fixing methods in their mechanical structure design. Common methods include bolt and nut fastening, which provides a relatively secure connection. However, installation and disassembly are time-consuming and labor-intensive. In terms of technical principles, they focus on static protection, relying on the outer shell material to block external dust and moisture intrusion.
[0004] Traditional prefabricated cable trays have increasingly numerous and complex internal cables, which can easily lead to redundant and disorderly cable accumulation inside the tray. This not only affects heat dissipation but also increases the risk of friction and short circuits between the cables. Therefore, a prefabricated cable tray is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an assembled cable outlet cover, which aims to improve the situation in the prior art where the cables inside the cable outlet cover are becoming increasingly numerous and complex, and the cables are prone to redundant lengths and disorderly accumulation inside the cable outlet cover. This not only affects heat dissipation, but also increases the risk of mutual friction and short circuits between the lines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A prefabricated cable outlet cover includes a mounting plate, a protective shell fixedly connected to the upper surface of the mounting plate, a cable outlet opening inside the protective shell, a sealing ring fixedly connected inside the protective shell, a fixing component inside the protective shell, and a sliding component inside the protective shell.
[0008] The fixing assembly includes a fixing block one, one side wall of which is fixedly connected to the inside of the protective shell, a tension band fixedly connected to one side wall of which, a fixing shell fixedly connected to the inside of the protective shell, a connecting plate fixedly connected to the inside of the fixing shell, a winding drum rotatably connected to the inside of the fixing shell, a rotating block fixedly connected to one end of the winding drum, a rotating block rotatably connected to the inside of the connecting plate, a clock spring fixedly connected to the side wall of the rotating block, a fixing block two fixedly connected to the side wall of the connecting plate, one end of the clock spring fixedly connected to the side wall of the fixing block two, and a retaining ring fixedly connected to the inside of the protective shell.
[0009] As a further description of the above technical solution:
[0010] The sliding assembly includes a sliding cover, the side wall of which is slidably connected to the inside of the protective shell, and a connecting strip is fixedly connected to the side wall of the sliding cover;
[0011] As a further description of the above technical solution:
[0012] One end of the stretching belt is fixedly connected to the side wall of the take-up drum, and the side wall of the take-up drum is rotatably connected to the inside of the connecting plate.
[0013] As a further description of the above technical solution:
[0014] The protective shell has a sliding groove inside, and the side wall of the connecting strip is slidably connected to the inside of the sliding groove;
[0015] As a further description of the above technical solution:
[0016] The upper surface of the sliding cover is fixedly connected with an anti-slip block to increase the friction of the sliding cover and facilitate its sliding motion.
[0017] As a further description of the above technical solution:
[0018] The protective shell has a first slot and a second slot inside.
[0019] As a further description of the above technical solution:
[0020] A spring seat is fixedly connected inside the connecting strip, and a spring coil is fixedly connected to the side wall of the spring seat;
[0021] As a further description of the above technical solution:
[0022] One end of the spring coil is fixedly connected to a locking block, and the side wall of the locking block is slidably connected inside the locking groove.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, pulling the pull cord causes the winding drum to rotate, which in turn causes the rotating block to drive the spring to contract. Then, by placing the excessively long cable on the side wall of the tension belt, the tension belt is released to allow the spring to rebound, thereby causing the winding drum to rotate again and winding the tension belt to tighten and secure the cable. Then, the side wall of the cable is clamped onto the retaining ring to further enhance the fixing effect. This solves the problem that in some assembled cable outlet covers, the cables inside are becoming increasingly numerous and complex, and the cables are prone to redundant lengths and disorderly accumulation inside the cable outlet cover. This not only affects heat dissipation but also increases the risk of mutual friction and short circuits between the lines. The above structure improves the practicality of the equipment.
[0025] 2. In this utility model, by pushing the anti-slip block, the sliding cover is moved to slide, causing the locking block to be squeezed and press against the spring ring, thereby disengaging from the first slot and sliding into the connecting strip. When the sliding cover slides the locking block to the second slot, the spring ring loses its compression, pushing the locking block to slide again and enter the second slot, achieving a fixing effect, thus facilitating the quick opening of the cable inside the protective shell for inspection.

[0033] 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.
[0034] Reference Figures 1-3 This utility model provides an embodiment of a prefabricated cable outlet cover, including a mounting plate 1. A protective shell 2 is fixedly connected to the upper surface of the mounting plate 1. A cable outlet 4 is provided inside the protective shell 2. A sealing ring 5, typically made of rubber or silicone, is fixedly connected inside the protective shell 2. The sealing ring 5 fits tightly against the cable outlet 4 and any gaps that may exist inside the protective shell 2, forming a tight barrier to effectively prevent dust, moisture, oil, and other impurities from entering the protective shell 2. The fixing and sliding components inside the protective shell 2 work together to optimize cable management. Among the fixing components, the fixing block 7 provides a stable connection base for subsequent components. A tension band 8 is fixedly connected to the side wall of fixing block 7. Inside the protective shell 2 is a fixing shell 9, inside which a connecting plate 10 is fixedly connected. A winding drum 11 is rotatably connected inside the fixing shell 9. One end of the winding drum 11 is fixedly connected to a rotating block 12. The side wall of the rotating block 12 is connected to the inside of the connecting plate 10 via a high-precision bearing. A spring 13 is fixedly connected to the side wall of the rotating block 12, utilizing its unique elastic energy storage characteristics to become the power source for cable winding. One end of the spring 13 is fixedly connected to the side wall of fixing block 14, which is typically a metal protrusion integrally formed with the connecting plate 10, providing a stable support point for the spring 13. The protective shell 2 is fixedly connected with a retaining ring 6. The retaining ring 6 can accurately lock the side wall of the cable, further enhancing the fixing effect of the cable and preventing the cable from falling out of the predetermined position due to accidental pulling or vibration. One end of the tension band 8 is fixedly connected to the side wall of the winding drum 11, ensuring the linkage effect between the tension band 8 and the winding drum 11. The side wall of the winding drum 11 is rotatably connected to the inside of the connecting plate 10, providing reliable mechanical support for the winding and management of the cable, and ensuring that the cable management function of the entire cable outlet cover can be realized efficiently.
[0035] When using this equipment, the mounting plate 1 is first installed at the terminal. Once the mounting plate 1 is in place, the outlet 4 serves as the channel for the cable to enter the protective housing 2. Its diameter is designed according to the outer diameter specifications of common cables to ensure smooth cable passage. The sealing ring 5, fixedly connected around the outlet 4, plays a crucial sealing barrier role. The sealing ring 5 is generally made of highly elastic, aging-resistant, and highly insulating rubber material, such as silicone rubber. When the cable is inserted through the outlet 4, the sealing ring 5 tightly adheres to the cable sheath, using its elastic deformation to fill the tiny gap between the cable and the outlet 4, forming a tight seal. This not only effectively prevents dust, moisture, oil, and other small particulate impurities from entering the protective housing 2, preventing their accumulation at the cable joint and causing short circuits, corrosion, and other electrical faults, but also reduces the impact of external electromagnetic interference on internal signal transmission to a certain extent, creating a clean and safe internal environment for stable operation after cable connection. After the cable is successfully inserted into the terminal inside the protective housing 2 and the basic connection is completed, the problem of redundant cable length often arises. At this time, it is necessary to effectively manage the excessively long cable. In this process, the tension band 8 becomes the key point of force for operation. One end is tightly fixed to the side wall of the winding drum 11, and the other end is connected to the fixing block 7, providing a reliable transmission path for the cable winding operation. When it is necessary to wind up the cable, the operator manually pulls the tension band 8, causing the winding drum 11 to be under force and start to rotate. The axis of the winding drum 11 is rigidly connected to the rotating block 12. The side wall of the rotating block 12 is rotatably connected to the inside of the connecting plate 10 through a high-precision bearing, so that the winding drum 11 can run smoothly with minimal friction when rotating. As the winding drum 11 rotates, the rotating block 12 rotates synchronously, thereby pulling the spring 13 to rotate and tighten. During the rotation and tightening process, the spring 13 continuously stores elastic potential energy. Next, the excess cable is neatly placed on the side wall of the tension band 8, and then the tension band 8 is released. At this time, the spring 13 quickly rebounds due to the previously stored elastic potential energy, causing the winding drum 11 to rotate in the opposite direction again. The winding drum 11 then winds up the tension band 8. During the winding process, the tension band 8 gradually tightens, applying appropriate radial pressure to the cable, tightly binding the cable together, thereby achieving initial fastening of the cable and effectively preventing the cable from rubbing or colliding with other components due to its own looseness or shaking, ensuring the stability of the cable connection. After completing the above cable winding and initial fastening steps, in order to further enhance the cable fixing effect, the retaining ring 6 is also needed. The retaining ring 6 provides additional clamping force from the side of the cable, complementing the fastening effect of the tension band 8. With this double protection, the cable is firmly fixed in the designated position inside the protective shell 2. Even if subjected to external forces such as vibration and pulling during equipment operation, the cable can always maintain a stable connection state, greatly reducing the risk of electrical faults caused by cable loosening, and laying a solid foundation for the safe and reliable operation of the entire electrical system.
[0036] Reference Figures 4-5 The sliding assembly includes a sliding cover 3, the side wall of which is slidably connected to the inside of the protective shell 2. This design ensures the stability of the sliding cover 3 during movement. A connecting strip 17 is fixedly connected to the side wall of the sliding cover 3. A sliding groove 16 is provided inside the protective shell 2, providing a dedicated sliding track for the connecting strip 17. The side wall of the connecting strip 17 slides stably inside the sliding groove 16. An anti-slip block 15 is fixedly connected to the upper surface of the sliding cover 3. The anti-slip block 15 can significantly increase the friction of the surface of the sliding cover 3, allowing the user to apply force more firmly when their hand contacts it. A first slot 21 and a second slot 22 are provided inside the protective shell 2. A spring seat 18 is fixedly connected inside the connecting strip 17. A spring ring 19 is fixedly connected to the side wall of the spring seat 18. A locking block 20 is fixedly connected to one end of the spring ring 19.
[0037] When it is necessary to inspect the cables inside the protective housing 2, the anti-slip block 15 located on the upper surface of the sliding cover 3 becomes the key point of force to initiate the inspection process. The anti-slip block 15 is usually made of rubber or silicone with a high coefficient of friction, and its surface is covered with fine and regular textures, which can significantly increase the friction between the hand and the sliding cover 3. When the operator needs to push the sliding cover 3, the fingers press on the anti-slip block 15, accurately transferring the force to the sliding cover 3. Its side wall is slidably connected to the slide rail structure inside the protective housing 2. As the sliding cover 3 slides up, the connecting strip 17 moves synchronously. Its side wall fits tightly with the slide groove 16, ensuring that the connecting strip 17 always moves stably along the track of the slide groove 16 during the sliding process of the sliding cover 3, providing solid support for the smooth movement of the sliding cover 3. At this time, the locking block 20 located inside the connecting strip 17 begins to play a key role. As the sliding cover 3 slides upward, the locking block 20 is pressed against the inner wall of the protective shell 2. Since the side wall of the locking block 20 and the inside of the connecting strip 17 are designed for sliding connection, the locking block 20 slides into the connecting strip 17, pressing against the spring coil 19. As the sliding cover 3 continues to slide, when the protective shell 2 gradually opens to the position of the second slot 22, the spring coil 19 loses the pressure from the inner wall of the protective shell 2, and its stored elastic potential energy is released instantly. Pushing the locking block 20 into the second slot 22, the locking block 20 forms a stable locking effect within the second slot 22, fixing the sliding cover 3 in its current position. This prevents the sliding cover 3 from accidentally sliding off and closing during maintenance due to accidental shaking or collision, providing maintenance personnel with a spacious and stable operating space. This greatly improves the convenience of operation, enabling them to conduct comprehensive and detailed maintenance of the cables inside the protective shell 2, promptly identify and resolve potential cable problems, and ensure the subsequent stable operation of the entire electrical system.
[0038] Working principle: When using this equipment, the mounting plate 1 is installed at the terminal, and then the cable is inserted into the terminal inside the protective shell 2 through the cable outlet 4. During this process, the sealing ring 5 enhances the sealing effect between the cable outlet 4 and the cable. When the cable connection is completed and it is necessary to wind up the excessively long cable, the tension belt 8 is pulled, causing the winding drum 11 to start rotating, which in turn drives the rotating block 12 to rotate, causing it to pull the spring 13 to rotate and tighten. At this time, the excess cable is placed on the side wall of the tension belt 8, and then the tension belt 8 is released, allowing the spring 13 to rebound and drive the winding drum 11 to rotate again and wind up the tension belt 8. This tightens and secures the cable. Then, the cable is inserted into the retaining ring 6 to further enhance the cable's fixation. When it is necessary to inspect the cable inside the protective shell 2, the anti-slip block 15 is pushed, causing the sliding cover 3 to slide upwards. This causes the retaining block 20 to be squeezed out of the slot 1 21 and slide into the connecting strip 17, squeezing the spring ring 19. As the sliding cover 3 slides, the protective shell 2 gradually opens. When it slides to the slot 22, the spring ring 19 loses its compression, pushing the retaining block 20 into the slot 22 to achieve a fixation effect. At this point, the internal cable can be inspected, greatly improving the ease of operation.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
