Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and more specifically, it relates to a power distribution cabinet for electrical engineering. Background Technology

[0002] In the installation and maintenance of power distribution systems in electrical engineering, distribution cabinets, as the core equipment for power distribution and control, need to accommodate a large number of power cables and control cables of different specifications and uses. Existing distribution cabinets have obvious deficiencies in cable arrangement. The cabinet interior is usually only equipped with simple cable trays or cable tie fixing points. This crude fixing method is difficult to meet the needs of complex cable layouts. When electrical engineers install the lines, due to the lack of effective cable fixing structures, multiple cables are easily tangled together, forming messy knots. This not only affects the rational use of the cabinet space, but also brings great difficulties to subsequent line inspection and troubleshooting. Especially when it is necessary to add or replace lines, due to the unsecured cables, pulling one cable often causes other cables to move as well, resulting in the disruption of the original wiring order. At the same time, cables that are not properly secured will vibrate due to electromagnetic forces during the operation of the distribution cabinet. Long-term vibration will not only cause wear on the cable insulation layer, increasing the risk of short circuits, but may also cause the terminals to loosen, affecting the reliability of power supply. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the problems existing in the prior art, this utility model provides a power distribution cabinet for electrical engineering to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet for electrical engineering, comprising a cabinet body, a fixed plate fixedly disposed inside the cabinet body, the fixed plate being provided with multiple sets of cable bundling mechanisms, each cable bundling mechanism comprising a mounting sleeve and clamping blocks, the mounting sleeve being fixed to the outer wall of the fixed plate, the outer wall of the mounting sleeve being provided with a movable groove, the movable groove being provided with multiple sets of damping rotating shafts mounted on the inner side of each set, the clamping blocks being provided with multiple sets of clamping blocks and rotatably connected to the multiple sets of damping rotating shafts respectively, and a limiting sleeve being slidably disposed on the outer wall of the mounting sleeve, the limiting sleeve abutting against the outer side of the multiple sets of clamping blocks.

[0007] The present invention is further configured such that an arc-shaped rod is fixedly provided on the outer side of the limiting sleeve, a rotating sleeve is rotatably provided on the outer wall of the mounting sleeve, and a limiting rod is fixedly provided on the outer wall of the rotating sleeve. The limiting rod is provided in multiple sets, and each of the limiting rods has a limiting hole on its outer wall. The limiting sleeve is reliably locked by the insertion and cooperation of the arc-shaped rod and the limiting rod, which prevents the cable from loosening due to vibration or external force in the fixed state. At the same time, the rotation operation mode of the rotating sleeve makes it easy for the operator to quickly complete the locking and unlocking actions, which improves the safety and convenience of cable fixing.

[0008] The present invention is further configured such that a tension spring is connected to the top surface of the limiting sleeve, and a thrust bearing is connected between the top end of the tension spring and the rotating sleeve. The tension spring provides a continuous elastic restoring force so that the limiting sleeve can automatically reset and release the pressure on the clamping block after unlocking. The setting of the thrust bearing reduces the frictional resistance when the rotating sleeve rotates, making the operation more effortless and smooth, and avoiding operational difficulties and component wear caused by excessive friction.

[0009] The present invention is further configured such that through holes are provided on the outer walls of multiple sets of fixing plates, which facilitates the passage of cables through different positions of the fixing plates, realizes flexible arrangement and zoned management of cable routing in the cabinet, and meets the needs of reasonable layout of multiple cables in complex power distribution systems.

[0010] The present invention is further configured such that rubber pads are connected to the inner sides of the multiple sets of clamping blocks. The rubber pads form flexible contact with the cable sheath, which increases the friction and improves the clamping effect, while avoiding direct pressure from hard materials that could damage the cable insulation layer and extend the service life of the cable.

[0011] The present invention is further configured such that a guide groove is provided on the outer wall of the mounting sleeve, and a guide block is fixedly provided on the inner side of the limiting sleeve. Multiple sets of guide grooves and guide blocks are provided and slidably connected. The cooperation between the guide grooves and guide blocks ensures that the limiting sleeve moves smoothly along a predetermined trajectory during the pushing and pulling process, avoiding skewing or jamming, and improving the accuracy and smoothness of operation.

[0012] The present invention is further configured such that the inner side of the rotating sleeve has a sliding hole, and the sliding hole is provided in multiple sets, each with a positioning block slidably mounted on its inner side; the outer wall of the mounting sleeve has a positioning groove, and the positioning groove is provided in multiple sets, each abutting against multiple sets of positioning blocks; the abutting cooperation between the positioning blocks and the positioning grooves provides precise positioning and stable support for the rotating sleeve in the locked position, preventing the rotating sleeve from rotating due to accidental contact and causing the locking to fail.

[0013] The present invention is further configured such that each of the multiple sets of positioning blocks and sliding holes is connected with a push spring. The push spring pushes the positioning block to continuously abut against the positioning groove, which enhances the stability of the rotating sleeve in the locked state. At the same time, when the rotating sleeve is rotated, the positioning groove can overcome the spring force of the push spring to push the positioning block into the sliding hole to achieve position switching, thus ensuring the reliable realization of the positioning and unlocking functions.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a power distribution cabinet for electrical engineering, which has the following advantages:

[0016] 1. This device provides stable and reliable support for cables inside the distribution cabinet by installing a fixing plate inside the cabinet and configuring a cable management structure on its outside. The cable management structure adopts a design that combines a mounting sleeve and a clamping block. The clamping block achieves smooth rotation through a damping shaft, and the inner rubber pads provide flexible clamping for the cables. This ensures sufficient fixing force to prevent the cables from loosening or shifting due to vibration during operation of the distribution cabinet, while also avoiding direct contact between hard materials and the cable insulation layer. At the same time, the contact between the limiting sleeve and the clamping block achieves automatic adjustment of the clamping force through the elastic action of the tension spring, so that cables of different diameters can achieve appropriate fixing effects. The distributed layout of multiple clamping blocks can form multiple fixing points inside the cabinet, effectively preventing cables from tangling and piling up in a disorderly manner. This makes the wiring inside the cabinet neat, standardized, easy to identify and inspect, and significantly improves the utilization rate of the internal space of the distribution cabinet and the standardization of cable management.

[0017] 2. The rotating sleeve and limiting rod combination structure of this device provides a convenient way to quickly install and remove cables. When it is necessary to inspect or replace the cable, the operator only needs to rotate the rotating sleeve to disengage the limiting rod from the limiting hole and release the constraint on the limiting sleeve. The tension spring then automatically pulls the limiting sleeve to release the clamping block from holding the cable. The entire release process is simple to operate and requires no tools, which greatly improves the efficiency of line maintenance. After the cable installation is completed, the cable can be quickly and firmly locked by pushing the limiting sleeve and rotating the rotating sleeve. The abutment of the positioning block and the positioning groove, combined with the elastic force of the push spring, ensures the stability of the rotating sleeve in the locked position and prevents accidental loosening due to accidental contact or vibration. The insertion structure of multiple sets of limiting rods and arc rods forms a multi-point locking effect, further enhancing the reliability of the fixation.

[0018] 3. This device features multiple sets of through holes on the fixing plate, along with multiple sets of cable bundle structures. This allows for flexible configuration based on the cable routing and quantity in different areas of the distribution cabinet, meeting the needs of multi-channel cable management in complex power distribution systems. The sliding fit between the guide groove and the guide block ensures the smooth movement and directional accuracy of the limit sleeve during the pushing and pulling process, preventing jamming. The application of the damping shaft provides appropriate damping during the opening and closing of the clamping block, facilitating precise control of the clamping state by the operator. The thrust bearing reduces the frictional resistance between the tension spring and the rotating sleeve, making the rotation of the rotating sleeve easier and smoother. The overall structure is reasonably compact, not occupying excessive cabinet space. Furthermore, all components are made of durable materials, adapting to the environmental requirements of long-term operation of the distribution cabinet. This effectively extends the service life of the cable fixing device, reduces the maintenance cost of the distribution cabinet, and significantly improves the safety, reliability, and maintainability of the electrical engineering power distribution system.

[0028] Please see Figures 1-5 An electrical engineering distribution cabinet includes a cabinet body 1. A fixing plate 2 is fixedly installed inside the cabinet body 1. The fixing plate 2 is provided with multiple sets, and each set has a wire harness mechanism on its outer side. The wire harness mechanism includes a mounting sleeve 3 and a clamping block 4. The mounting sleeve 3 is fixed to the outer wall of the fixing plate 2. The outer wall of the mounting sleeve 3 has a movable groove 5. Multiple sets of movable grooves 5 are provided, and each set has a damping rotating shaft 6 installed on its inner side. Multiple sets of clamping blocks 4 are provided and are rotatably connected to multiple sets of damping rotating shafts 6. A limiting sleeve 7 is slidably provided on the outer wall of the mounting sleeve 3 and abuts against the outer side of the multiple sets of clamping blocks 4.

[0029] An arc-shaped rod 8 is fixedly provided on the outer side of the limiting sleeve 7. A rotating sleeve 9 is rotatably provided on the outer wall of the mounting sleeve 3. A limiting rod 10 is fixedly provided on the outer wall of the rotating sleeve 9. Multiple sets of limiting rods 10 are provided, and each has a limiting hole 11 on its outer wall.

[0030] A tension spring 12 is connected to the top surface of the limiting sleeve 7, and a thrust bearing 13 is connected between the top of the tension spring 12 and the rotating sleeve 9.

[0031] Multiple sets of fixing plates 2 have through holes 14 on their outer walls.

[0032] Rubber pads 15 are connected to the inner side of multiple clamping blocks 4.

[0033] The outer wall of the mounting sleeve 3 is provided with a guide groove 16, and the inner side of the limiting sleeve 7 is fixed with a guide block 17. The guide groove 16 and the guide block 17 are provided in multiple sets and are slidably connected.

[0034] The inner side of the rotating sleeve 9 is provided with a sliding hole 180. Multiple sets of sliding holes 180 are provided, and each of them is provided with a positioning block 18. The outer wall of the mounting sleeve 3 is provided with a positioning groove 19. Multiple sets of positioning grooves 19 are provided and abut against multiple sets of positioning blocks 18 respectively.

[0035] Push springs 20 are provided between each set of positioning blocks 18 and sliding holes 180.

[0036] In this embodiment, during use, the cable inside the cabinet 1 is passed through the mounting sleeve 3, the limiting sleeve 7 is pushed to stretch the tension spring 12 and cause it to push multiple sets of clamping blocks 4 to rotate along the damping shaft 6, so that the rubber pad 15 clamps the outside of the cable. Then, the rotating sleeve 9 is rotated to drive multiple sets of limiting rods 10 to rotate and insert into the arc-shaped rod 8, thereby limiting the limiting sleeve 7. Multiple sets of push springs 20 push the positioning block 18 to abut against the positioning groove 19 to position the rotating sleeve 9, thus completing the fixing of the cable.

[0037] More specifically, when disassembling the cable, while rotating the rotating sleeve 9, multiple positioning grooves 19 push the positioning blocks 18 to slide into the sliding holes 180 and compress the push spring 20, so that the multiple positioning blocks 18 move along the multiple positioning grooves 19. The rotation of the rotating sleeve 9 drives multiple limiting rods 10 to disengage the multiple arc-shaped rods 8 from the limiting holes 11 and release the limitation sleeve 7. The tension spring 12 pulls the limiting sleeve 7 to release the contact with the outer wall of the multiple clamping blocks 4, thereby releasing the clamping of the cable by the multiple clamping blocks 4, and then the cable can be disassembled.

[0038] In summary, when using or operating the overall equipment: When in use, the cable inside the cabinet 1 is passed through the mounting sleeve 3, the limiting sleeve 7 is pushed to stretch the tension spring 12, which in turn pushes multiple sets of clamping blocks 4 to rotate along the damping shaft 6, causing the rubber pad 15 to clamp the outside of the cable. Then, the rotating sleeve 9 is rotated to drive multiple sets of limiting rods 10 to rotate and insert into the arc-shaped rod 8, thereby limiting the limiting sleeve 7. Multiple sets of push springs 20 push the positioning block 18 to abut against the positioning groove 19 to position the rotating sleeve 9, thus completing the fixing of the cable.

[0039] When disassembling the cable, rotating the rotating sleeve 9 simultaneously pushes the positioning block 18 into the sliding hole and compresses the push spring 20, causing the positioning block 18 to move along the positioning groove 19. The rotating sleeve 9 rotates and drives the limiting rods 10 to disengage the arc rods 8 from the limiting hole 11, releasing the limitation of the limiting sleeve 7. The tension spring 12 pulls the limiting sleeve 7 to release the contact with the outer wall of the clamping blocks 4, thereby releasing the clamping of the cable by the clamping blocks 4, and then the cable can be disassembled.
