Description

Technical Field

[0001] This utility model relates to the field of electrical engineering construction technology, and more specifically, it relates to an electrical engineering exposed wire protection device. Background Technology

[0002] In electrical engineering construction, cables are a crucial transmission medium, widely used for power supply, signal transmission, and equipment connection. However, due to the complex construction environment, some cables are inevitably exposed, such as temporary wiring, overhead lines, or wires connecting equipment. These exposed cables are susceptible to external factors, such as mechanical compression, pulling, trampling, and even corrosion under severe weather conditions, which can lead to cable damage, signal attenuation, or unstable power transmission. Therefore, during construction, there is an urgent need for a device that can effectively protect exposed cables to reduce damage to cables from the external environment and ensure the safety and stability of power and signal transmission.

[0003] Currently, some cable protection devices on the market have certain limitations in installation and disassembly, especially when dealing with cables of different diameters and materials, they often lack flexibility and are difficult to meet various construction needs. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides an electrical engineering exposed wire protection device to solve the technical problem mentioned in the background art that some cable protection devices on the market have certain limitations in installation and disassembly.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrical engineering exposed wire protection device, comprising a mounting base, on which a wire harnessing mechanism is provided. The wire harnessing mechanism includes a connecting plate, a fixing sleeve, a threaded sleeve, a screw, a wire harness clamp, a transmission sleeve, a relief groove, a rack, an external gear, and a linkage mechanism. The connecting plate is installed at both ends of the mounting base, the fixing sleeve is fixed inside the connecting plate, multiple sets of threaded sleeves are installed inside the fixing sleeve, the screw is connected to the inner side of multiple sets of threaded sleeves, the wire harness clamp is located at the bottom end of multiple sets of screws, and two sets of transmission sleeves slide outside the fixing sleeve. The wall has multiple sets of clearance grooves distributed on the outer sides of the two sets of transmission sleeves. The rack is installed on one side of the multiple sets of clearance grooves. The external gear rotates on the top of the multiple sets of threaded sleeves and meshes with the multiple sets of racks. The linkage mechanism includes a limiting ring, a rotating sleeve, a gear ring, a transmission rod, an internal gear, and a transmission block. The limiting ring is fixed to the outer wall of the fixed sleeve. The rotating sleeve is rotatably installed on the outer wall of the fixed sleeve. The gear ring is installed on the inner wall of the rotating sleeve. The transmission rod has multiple sets that rotatably connect the limiting ring and the connecting plate. The transmission block has multiple sets that are fixed to the outer walls of the two sets of transmission sleeves and threadedly connected to the multiple sets of transmission blocks.

[0008] The present invention is further configured such that a limiting mechanism is provided at the top of the fixed sleeve, the limiting mechanism including a mounting ring, a limiting block, a limiting groove, a return spring, a push spring, and a sliding sleeve. The mounting ring is fixed to the top of the rotating sleeve, the limiting block is provided with multiple sets sliding inside the mounting ring, the limiting groove is provided with multiple sets distributed on the outer wall of the fixed sleeve, the return spring is installed on the top of the multiple sets of limiting blocks and connected to the outer wall of the mounting ring, the push spring is provided with multiple sets fixed on one side of the connecting plate, and the sliding sleeve slides on the outer wall of the fixed sleeve and is connected to the multiple sets of push springs.

[0009] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a guide groove, and the inner walls of both sets of transmission sleeves are provided with guide strips. Multiple sets of guide grooves and guide strips are provided and slidably connected. This configuration, through the slidable connection of the guide grooves and guide strips, ensures that the transmission sleeve moves more smoothly, reduces friction, and thus improves the stability and accuracy of the entire device.

[0010] This invention is further configured such that each of the multiple sets of screws is equipped with a limiting plate at its top, and the multiple sets of limiting plates are slidably connected to the multiple sets of external gears. The slidable connection between the limiting plates and the external gears effectively limits the rotation range of the screws, preventing excessive rotation or malfunction of the screws, thereby ensuring precise control and safety of the device.

[0011] The present invention is further configured such that all of the multiple sets of limiting plates are cross-shaped. The cross-shaped limiting plate design improves the contact stability with the external gear, enhances the limiting effect, ensures a tighter fit between components, and thus improves the reliability and durability of the system.

[0012] This invention is further configured such that the bottom ends of the multiple sets of screws are rotatably connected to the multiple sets of cable clamps. This rotatable connection between the screws and the cable clamps ensures that the cable clamps can be precisely adjusted according to the rotation of the screws, effectively fixing or loosening the cables, thus ensuring the efficiency and safety of the cable bundling process.

[0013] This invention is further configured such that rubber strips are installed on the inner sides of multiple sets of cable clamps, with several sets of rubber strips distributed on the inner sides of the multiple sets of cable clamps. The rubber strips provide a cushioning effect, reducing wear and pressure on the cables, preventing damage to the cables due to excessive tightening, and ensuring effective protection of the cables during the clamping process.

[0014] This invention is further configured such that both ends of the multiple sets of limiting blocks and the limiting grooves are all designed with arc-shaped surfaces. The arc-shaped surface design of the limiting blocks and the limiting grooves reduces friction and jamming, allowing the limiting blocks to slide more smoothly within the limiting grooves, thus enhancing the smoothness and reliability of the device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a protection device for exposed wires in electrical engineering, which has the following advantages:

[0017] 1. The cable harnessing mechanism, through the cooperation of the screw and the cable clamp, can effectively fasten the cable and ensure its secure fixation within the protective device. When the screw rotates, the cable clamp is pushed against the outer wall of the cable body through the cooperation of the screw sleeve and the screw, clamping the cable and preventing the cable from being pulled or squeezed and damaged in the external environment. Because the inner wall of the cable clamp is equipped with a rubber strip, it can provide a certain cushioning effect, reduce wear on the cable surface, and effectively avoid damage to the cable due to excessive tightening. In addition, the cable harnessing mechanism adopts a sliding transmission sleeve and guide bar design, making the entire cable harnessing process smoother, reducing jamming, and improving the flexibility and stability of use.

[0018] 2. The beneficial effects of the linkage mechanism are reflected in its precise transmission and efficient adjustment function. By rotating the sleeve to drive the meshing transmission of the gear ring and internal gear, it can smoothly drive the transmission rod and transmission block for fine adjustment. The transmission block is connected to the transmission rod by threads, which ensures the coordination between various components, so that the wire clamp can apply pressure evenly, ensuring that the wire is firmly fixed and does not loosen. The structural design of the linkage mechanism can realize the simultaneous control of multiple sets of wire clamps, improve the overall performance and reliability of the device, and make disassembly and reinstallation easier, adapting to the needs of different construction sites.

[0019] 3. The limiting mechanism ensures the correct fixation of the cable clamp while providing an adjustable safety locking function. Through the cooperation of the limiting block and the limiting groove, the rotating sleeve can be firmly locked in the fixed state, preventing accidental loosening or displacement during use. When it is necessary to remove the cable, the limiting mechanism can quickly release the restriction on the rotating sleeve. Through the elastic action of the return spring and the push of the push spring, the locking is successfully completed and the rotating sleeve is allowed to rotate, thereby driving the screw to loosen and easily disassembling the cable. This design greatly improves the convenience of operation, avoids unnecessary damage to the device, and ensures the protection of the cable and the efficiency and smoothness of the disassembly and assembly process during construction.

[0029] Please see Figures 1-5 An electrical engineering exposed wire protection device includes a mounting base 1, on which a wire harnessing mechanism is provided. The wire harnessing mechanism includes a connecting plate 2, a fixing sleeve 3, a screw sleeve 4, a screw 5, a wire harness clamp 6, a transmission sleeve 7, a relief groove 8, a rack 9, an external gear 10, and a linkage mechanism. The connecting plate 2 is installed at both ends of the mounting base 1, the fixing sleeve 3 is fixed inside the connecting plate 2, multiple sets of screw sleeves 4 are installed inside the fixing sleeve 3, the screw 5 is connected to the inner side of the multiple sets of screw sleeves 4, the wire harness clamp 6 is located at the bottom end of the multiple sets of screws 5, two sets of transmission sleeves 7 are provided sliding on the outer wall of the fixing sleeve 3, and multiple sets of relief grooves 8 are provided distributed on the two sets of transmission sleeves 3. On the outside of sleeve 7, rack 9 is installed on one side of multiple sets of clearance grooves 8. External gear 10 rotates on the top of multiple sets of threaded sleeves 4 and meshes with multiple sets of rack 9 respectively. The linkage mechanism includes a limiting ring 11, a rotating sleeve 12, a gear ring 13, a transmission rod 14, an internal gear 15, and a transmission block 16. The limiting ring 11 is fixed to the outer wall of the fixed sleeve 3. The rotating sleeve 12 is rotatably installed on the outer wall of the fixed sleeve 3. The gear ring 13 is installed on the inner wall of the rotating sleeve 12. The transmission rod 14 is provided with multiple sets of rotatably connected to the limiting ring 11 and the connecting plate 2. The transmission block 16 is provided with multiple sets of fixed to the outer walls of the two sets of transmission sleeves 7 and threadedly connected to multiple sets of transmission blocks 16 respectively.

[0030] The top of the fixed sleeve 3 is provided with a limiting mechanism, which includes a mounting ring 17, a limiting block 18, a limiting groove 19, a return spring 20, a push spring 21, and a sliding sleeve 22. The mounting ring 17 is fixed to the top of the rotating sleeve 12. The limiting block 18 is provided with multiple sets that slide within the mounting ring 17. The limiting groove 19 is provided with multiple sets that are distributed on the outer wall of the fixed sleeve 3. The return spring 20 is installed on the top of multiple sets of limiting blocks 18 and connected to the outer wall of the mounting ring 17. The push spring 21 is provided with multiple sets that are fixed to one side of the connecting plate 2. The sliding sleeve 22 slides on the outer wall of the fixed sleeve 3 and is connected to multiple sets of push springs 21.

[0031] The outer wall of the fixed sleeve 3 is provided with a guide groove 23, and the inner walls of both sets of transmission sleeves 7 are provided with guide bars 24. Multiple sets of guide grooves 23 and guide bars 24 are provided and are slidably connected. The sliding connection principle of guide grooves 23 and guide bars 24 is to reduce friction through smooth guiding cooperation, so as to ensure that the transmission sleeves 7 can move stably and smoothly during operation, thereby improving the working efficiency and accuracy of the system.

[0032] Each of the multiple sets of screws 5 is equipped with a limiting plate 25 at its top, and the multiple sets of limiting plates 25 are slidably connected to multiple sets of external gears 10. The principle of the sliding connection between the limiting plate 25 and the external gear 10 is to limit the rotation range of the screws 5, avoid excessive rotation or malfunction, thereby ensuring the stability and control accuracy of the device and ensuring the coordinated work of each component.

[0033] All sets of limiting plates 25 are set in a cross shape. The design principle of the cross-shaped limiting plate 25 is to increase the contact area with the external gear 10, so that the connection between the limiting plate and the external gear is more stable, reducing the deviation that may occur during sliding, thereby enhancing the reliability and durability of the entire system.

[0034] The bottom ends of multiple sets of screws 5 are rotatably connected to multiple sets of cable clamps 6. The principle of the rotatable connection between the screws 5 and the cable clamps 6 is that the rotation of the screws drives the rotation of the cable clamps 6, thereby achieving precise clamping or loosening of the cables, ensuring that the cables are effectively protected and accurately adjusted during the fixing process.

[0035] Rubber strips 26 are installed on the inner side of multiple sets of cable clamps 6. Several sets of rubber strips 26 are arranged on the inner side of the multiple sets of cable clamps 6. The principle of setting rubber strips 26 is to provide a buffering effect for the cable clamps 6, reduce friction and pressure on the cables, prevent damage to the cable surface, and ensure uniform pressure distribution through the distribution of multiple sets of rubber strips, further protecting the cables.

[0036] Both ends of the multiple sets of limiting blocks 18 and the limiting grooves 19 are set with arc-shaped surfaces. The arc-shaped surface design principle of the limiting blocks 18 and the limiting grooves 19 is to reduce friction and jamming, so that the limiting blocks can slide smoothly in the limiting grooves, improving the smoothness and stability of the device operation, and avoiding wear and system failure caused by excessive friction.

[0037] In this embodiment, when it is necessary to fix the wire body, the wire body is passed through the multiple sets of wire clamps 6 in the fixing sleeve 3, and then the sliding sleeve 22 is pushed upward to squeeze the multiple sets of push springs 21, thereby releasing the contact between the inner wall of the sliding sleeve 22 and the top of the multiple sets of limiting blocks 18. The elastic reset of the multiple sets of return springs 20 pulls the limiting blocks 18 outward and makes their bottom ends disengage from the limiting grooves 19, releasing the restriction on the rotating sleeve 12. Then, the rotating sleeve 12 is rotated to drive the gear ring 13 to rotate. The gear ring 13 meshes with the multiple sets of internal gears 15, thereby driving the multiple sets of transmission rods 14 to rotate through the multiple sets of internal gears 15. The multiple sets of transmission rods 14 are threadedly engaged with the multiple sets of transmission blocks 16, thereby driving the multiple sets of transmission blocks 16 to move along the transmission rods 14, and at the same time driving the two sets of transmission sleeves 7 to slide. The transmission sleeves 7 slide along the guide grooves 23 through the guide strips 24, while driving the multiple sets of racks 9 and external gears. 10 engages in a meshing transmission, thereby driving the screw 5 to rotate through multiple sets of external gears 10. The screw 5 rotates and engages with the threaded sleeve 4, pushing the cable clamp 6 to contact the outer wall of the cable body. The screw 5 slides along the external gear 10 through multiple sets of limiting plates 25. The rubber strips 26 on the inner wall of the multiple sets of cable clamps 6 contact and clamp the outer wall of the cable body. Then, the sliding sleeve 22 is released, and multiple sets of push springs 21 push the sliding sleeve 22 to abut against the top of multiple sets of limiting blocks 18, thereby pushing the multiple sets of limiting blocks 18 so that their bottom ends are engaged in the limiting groove 19 and squeezing the multiple sets of return springs 20, thus completing the fixation of the cable body. When disassembly is required, the limiting mechanism restricts the rotating sleeve 12, and the rotating sleeve 12 rotates in the opposite direction, driving multiple sets of transmission sleeves 7 to engage with the external gear 10 in the opposite direction through the linkage mechanism. The screw 5 and the threaded sleeve 4 engage with the cable clamp 6 to disengage from the cable body, thus allowing the cable body to be disassembled.

[0038] In summary, during use or operation of the overall equipment: when it is necessary to fix the cable, the cable is passed through the multiple sets of cable clamps 6 in the fixing sleeve 3, and then the sliding sleeve 22 is pushed upward to squeeze the multiple sets of push springs 21, thereby releasing the contact between the inner wall of the sliding sleeve 22 and the top of the multiple sets of limiting blocks 18. The elastic reset of the multiple sets of return springs 20 pulls the limiting blocks 18 outward and makes their bottom ends disengage from the limiting grooves 19, releasing the restriction on the rotating sleeve 12. Then, rotating the rotating sleeve 12 drives the gear ring 13 to rotate. The gear ring 13 meshes with the multiple sets of internal gears 15, thereby driving the multiple sets of transmission rods 14 to rotate. The multiple sets of transmission rods 14 are threadedly engaged with the multiple sets of transmission blocks 16, thereby driving the multiple sets of transmission blocks 16 to move along the transmission rods 14, and at the same time driving the two sets of transmission sleeves 7 to slide. The transmission sleeves 7 slide along the guide grooves 23 through the guide strips 24, while driving the multiple sets of racks 9. The screw 5 rotates through multiple sets of external gears 10, meshing with the external gear 10. The screw 5 rotates and engages with the threaded sleeve 4, pushing the cable clamp 6 to contact the outer wall of the cable body. The screw 5 slides along the external gear 10 through multiple sets of limiting plates 25. The rubber strips 26 on the inner wall of the multiple sets of cable clamp 6 contact and clamp the outer wall of the cable body. Then, the sliding sleeve 22 is released, and multiple sets of push springs 21 push the sliding sleeve 22 to abut against the top of multiple sets of limiting blocks 18, thereby pushing the bottom of the multiple sets of limiting blocks 18 to engage in the limiting groove 19 and squeezing the multiple sets of return springs 20 to complete the fixation of the cable body. When disassembly is required, the limiting mechanism restricts the rotating sleeve 12, and the rotating sleeve 12 rotates in the opposite direction. Through the linkage mechanism, multiple sets of transmission sleeves 7 engage with the external gear 10 in the opposite direction. The screw 5 and the threaded sleeve 4 cooperate to drive the cable clamp 6 to disengage from the cable body, and the cable body can be disassembled.
