Description

Technical Field

[0001] This invention belongs to the technical field of cable branch boxes, and specifically relates to a low-voltage cable branch box with a layered layout. Background Technology

[0002] Low-voltage cable distribution boxes are cable branching and distribution devices with a rated voltage of 0.4kV used in low-voltage power distribution systems. They have functions of cable branching, splicing, conversion and power distribution. Circuit breakers and fuses can be selected to achieve protection and isolation. They are widely used in indoor and outdoor scenarios such as residential areas, municipal roads, factories, and rural power grids. They simplify wiring and improve power supply reliability, and are key supporting equipment for low-voltage cable distribution networks.

[0003] Currently, cables inside the boxes are mostly piled up haphazardly or bundled into a single fixed bundle. When disassembling and assembling cables, the bundled components need to be disassembled separately, which is a cumbersome operation. In addition, the brackets inside the boxes are mostly fixed structures, and their positions cannot be adjusted according to maintenance needs. Operators also find it difficult to get close to the wiring points. Therefore, a low-voltage cable branch box with a layered layout is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a low-voltage cable branch box with a layered layout that is easy to move and maintain, in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A low-voltage cable branch box with a layered layout includes a box body and doors hinged to both sides of the box body. A shelf is rotatably mounted on the box body on one side of the door. A stand is slidably mounted on the box body. Multiple shelves are mounted on the stand. A limit mechanism is provided on the stand. It also includes: A wire harnessing mechanism is disposed on the lower surface of the housing. The wire harnessing mechanism includes a mounting base that is fixedly disposed through the lower surface of the housing. A rotating plate is rotatably disposed on the mounting base. A telescopic rod is fixedly disposed on the rotating plate. A clamping plate assembly is disposed between the rotating plate and the mounting base. The linkage mechanism is mounted on the box body and includes a first link and a second link that are slidably mounted on the box body. The first link is rotatably connected to the telescopic rod. An inclined arc plate is fixedly mounted on both the first link and the second link, and the inclined arc plate movably abuts against the shelf. A limiting seat is fixedly installed on both sides of the housing, and the limiting mechanism is movably connected to the limiting seat.

[0006] As a further optimization of the present invention, a synchronizing rod is fixedly provided between the first connecting rod and the second connecting rod, and a spring is connected between the second connecting rod and the first connecting rod and the housing. The inclined arc plate is slidably disposed on the housing.

[0007] As a further optimization of the present invention, the mounting base has a through hole in the middle, the mounting base has an array of sliding grooves, and the rotating plate has a sliding groove.

[0008] As a further optimization of the present invention, the clamping plate assembly includes multiple plates, a slider one is fixedly disposed on the plate, the slider one is slidably disposed in a slide groove one, a slider two is fixedly disposed on the lower surface of the plate, the slider two is slidably disposed in a slide groove two, and a rubber plate is fixedly disposed at the end of the plate.

[0009] As a further optimization of the present invention, a horizontal axis is fixedly installed on the shelf, and semicircular blocks are fixedly installed at both ends of the horizontal axis. An installation block is sleeved on the semicircular block, and a fan-shaped groove is opened on the installation block. The semicircular block is embedded in the fan-shaped groove.

[0010] As a further optimization of the present invention, the limiting mechanism includes a fixed handle fixedly disposed on both sides of the upright, a guide rod fixedly disposed on the fixed handle, a sliding handle slidably disposed on the guide rod, a movable part slidably disposed on the upright, an embedded block fixedly disposed on the movable part, and the embedded block slidably disposed through the upright.

[0011] As a further optimization of the present invention, the movable component includes a movable seat, the embedded block is fixedly mounted on the movable seat, the movable seat has a V-shaped groove, a vertical rod fixedly mounted on a sliding handle is slidably mounted in the V-shaped groove, a sliding rod is fixedly mounted on the vertical frame, the movable seat is slidably mounted on the sliding rod, and a second spring is sleeved on the sliding rod, with the two ends of the second spring respectively fixedly mounted on the movable seat and the sliding rod.

[0012] As a further optimization of the present invention, the limiting seat array has multiple limiting slots, and the embedding block is movably embedded in the limiting slots.

[0013] As a further optimization of the present invention, the box body is provided with a receiving compartment, the first connecting rod and the second connecting rod are slidably disposed in the receiving compartment, the box body is provided with a clearance groove, and the inclined arc plate is slidably disposed through the clearance groove.

[0014] As a further optimization of the present invention, guide rails are fixedly provided on both sides of the box body, and the upright is slidably arranged on the guide rails.

[0015] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, in actual use, the uprights and multi-layer racks that slide inside the box, along with the locking mechanism and the limiting seat, enable the uprights to be adjusted along the guide rail. Operators can adjust the position of the multi-layer racks as needed and inspect cables at close range.

[0016] 2. Unlike existing technologies, in actual use, the linkage mechanism enables the rack and cable management mechanism to open and close in tandem. Pulling down the rack will cause the rotating plate to rotate via the inclined arc plate, connecting rod 1, and telescopic rod, which will automatically open the clamping plate to release the cable, eliminating the need to disassemble the cable separately. At the same time, the rack can be used to temporarily place tools, improving the convenience of operation. Attached Figure Description

Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1, as Figure 1 - Figure 11 As shown, a low-voltage cable branch box with a layered layout includes a box body 1 and box doors 11 symmetrically hinged on the left and right sides of the box body 1. The box body 1 integrates a sliding stand 2, a flip-up shelf 3, a cable bundling mechanism 4, a linkage mechanism 5, a limiting mechanism 6, and a limiting seat 7. The entire structure realizes the integrated functions of layered wiring, convenient maintenance, and automatic cable bundling. The layout is compact and orderly, and it is fully adaptable to low-voltage cable multi-branch wiring and daily operation and maintenance scenarios. Guide rails 22 are fixedly installed on the inner walls of both sides of the enclosure 1. The upright frame 2 is slidably engaged with the guide rails 22 and can slide and adjust along the depth direction of the enclosure 1. The upright frame 2 is provided with multiple shelves 21 at equal intervals along the vertical direction to form a multi-layer partitioned wiring structure, which can realize the orderly arrangement of low-voltage cables in layers and completely avoid the cross-tangling of cables. The inner walls of both sides of the enclosure 1 are fixedly welded with limiting seats 7 at the positions of the upright frame 2. Multiple limiting slots 71 are arrayed along the length direction of the limiting seats 7 to cooperate with the limiting mechanism 6 to complete the positioning and locking of the upright frame 2 after sliding, ensuring the stability of the wiring state.

[0021] like Figure 2 and Figure 7 - Figure 11As shown, the shelf 3 is mainly used for temporary placement of tools and wiring accessories during maintenance, further improving the convenience of operation. A horizontal shaft 31 is fixedly welded to the side of the shelf 3 near the box 1. Semicircular blocks 311 are integrally formed at both ends of the horizontal shaft 31. An installation block 32 is fixedly installed on the inner wall of the box 1 at the corresponding position. A fan-shaped groove 321 is opened on the installation block 32. The semicircular block 311 is embedded in the fan-shaped groove 321 and forms a rotational fit, which can limit the flipping angle of the shelf 3 and prevent excessive flipping and falling off. The limiting mechanism 6 is fixedly installed on both sides of the upright frame 2, forming a movable locking relationship with the limiting seat 7. The limiting mechanism 6 includes a fixing handle 61 welded to the outer wall of both sides of the upright frame 2. A guide rod 611 is vertically fixed on the fixing handle 61, and a sliding handle 62 is slidably sleeved on the guide rod 611. A sliding rod 634 is fixed on the inner wall of the upright frame 2. A movable part 63 is slidably assembled on the sliding rod 634. The movable part 63 includes a movable seat 631, which is slidably sleeved on the sliding rod 634. A second spring 635 is sleeved on the outside of the sliding rod 634. The two ends of the second spring 635 are respectively connected to the movable seat 631 and the sliding rod 634. 4. Fixed connection to achieve automatic reset of movable seat 631; V-shaped groove 633 is provided on movable seat 631, and upright rod 632 is fixed at the bottom of sliding handle 62. Upright rod 632 is slidably embedded in V-shaped groove 633. Through the set V-shaped groove 633, the movable seat 631 can be moved by moving sliding handle 62 to either side. An embedded block 64 is fixed on one side of movable seat 631. Embedded block 64 penetrates the side wall of upright 2 and is movably engaged with limiting groove 71 of limiting seat 7. By engaging and disengaging embedded block 64 with limiting groove 71, the limiting and unlocking of upright 2 can be quickly achieved.

[0022] like Figure 2 - Figure 6As shown, the cable management mechanism 4 is fixedly installed on the lower surface of the enclosure 1, specifically for securing low-voltage cables entering and exiting the enclosure 1, preventing cable swaying and pulling. This mechanism includes a mounting base 41 fixedly embedded in the lower surface of the enclosure 1. The mounting base 41 has a through hole 411 in the center for multiple low-voltage cables to pass through. The upper surface of the mounting base 41 has a ring-shaped array of multiple sliding grooves 412. A rotating plate 43 is rotatably mounted at the bottom, with corresponding multiple sliding grooves 431 on the rotating plate 43. The mounting base 41 and the rotating plate 43... A clamping plate assembly 42 is provided between the plates. The clamping plate assembly 42 includes multiple arc-shaped plates 421. A slider 422 is fixed to the top of the plate 421 and slides and engages in the groove 412. A slider 423 is fixed to the bottom of the plate 421 and slides and engages in the groove 431. A rubber plate 424 is attached to the inner side of the plate 421 to increase the friction with the cable and avoid scratching the cable insulation layer. The rotating plate 43 is fixed to one end of the telescopic rod 44, and the other end of the telescopic rod 44 is linked with the linkage mechanism 5. The linkage mechanism 5 is installed inside the receiving compartment 12 inside the housing 1. Its core function is to realize the linkage between the flipping of the shelf 3 and the opening and closing of the cable management mechanism 4. Specifically, it includes connecting rod 1 51 and connecting rod 2 52, which are slidably installed in the receiving compartment 12. A synchronizing rod 53 is fixedly connected between connecting rod 1 51 and connecting rod 2 52 to ensure that the two slide synchronously. A spring 1 55 is connected between the end of connecting rod 1 51 and connecting rod 2 52 and the inner wall of the receiving compartment 12 to realize the automatic reset of the connecting rod assembly. An inclined arc plate 54 is fixed at the top of connecting rod 1 51 and connecting rod 2 52. A corresponding clearance groove 13 is opened at the bottom of the housing 1. The inclined arc plate 54 passes through the clearance groove 13 and extends upward to form a movable abutment with the bottom of the shelf 3. The end of connecting rod 1 51 is rotatably connected to the telescopic rod 44. The lateral movement of connecting rod 1 51 drives the telescopic rod 44 to swing, thereby driving the rotating plate 43 to rotate, thus completing the linkage control of the cable tension.

[0023] It should be noted that during actual operation and maintenance, the operator opens the door 11 on either side of the cabinet 1 and manually flips the shelf 3 downwards. The semi-circular block 311 at the end of the horizontal axis 31 rotates along the fan-shaped groove 321 of the mounting block 32, limiting the flipping angle. During the downward movement of the shelf 3, the bottom will press against the inclined arc plate 54 of the linkage mechanism 5, pushing the inclined arc plate 54 to slide along the clearance groove 13 towards the inside of the cabinet 1 until the shelf 3 is horizontal. The side wall of the shelf 3 abuts against the inclined arc plate 54 and is fixed. During this process, the inclined arc plate 54 drives the connecting rod 1 51 and the connecting rod 2 52 to move horizontally synchronously within the receiving compartment 12. The synchronous rod 53 ensures that the connecting rod 1 51 and the connecting rod 2 52 on both sides move horizontally. 2. With synchronized action, spring 55 is stretched and undergoes elastic deformation; as connecting rod 51 moves laterally, it drives telescopic rod 44 to swing, thereby driving the rotating plate 43 of the cable harness mechanism 4 to rotate relative to the mounting base 41. During the rotation of the rotating plate 43, the sliding groove 431 moves synchronously, driving the slider 423 of the clamping plate group 42 to slide along the sliding groove 431. At the same time, slider 422 slides outward along the sliding groove 412 of the mounting base 41. Multiple plates 421 open synchronously, and rubber plate 424 detaches from the outer wall of the cable, completely releasing the cable harness binding the low-voltage cable passing through the through hole 411, allowing the cable to move freely and providing convenience for subsequent wiring and maintenance. Afterwards, the operator manually pulls the sliding handle 62 of the limiting mechanism 6, causing it to slide outward along the guide rod 611 on the fixed handle 61. The upright rod 632 at the bottom of the sliding handle 62 moves outward and slides in the V-groove 633 of the movable seat 631. The pressure on the inner wall of the V-groove 633 drives the movable seat 631 to slide outward along the sliding rod 634, compressing the second spring 635. This causes the embedded block 64 to move outward synchronously and exit the limiting groove 71 on the limiting seat 7, completely releasing the limiting constraint on the upright 2. At this time, the operator can pull the upright 2 horizontally, causing it to slide along the guide rails 22 on both sides of the box 1 towards the box door 11, adjusting the multi-layer shelf 21 to a position close to the operator. With the cables that have been loosened, the difficulty of maintenance and wiring is greatly reduced, and the operator is prevented from going deep into the box 1 to operate, thus comprehensively improving the safety and convenience of operation.

[0024] After the low-voltage cable maintenance and wiring work is completed, the operator first pushes the upright frame 2 back to the preset position inside the box 1 along the guide rail 22, releases the sliding handle 62, the spring 635 rebounds and pushes the movable seat 631 back to reset, the embedded block 64 re-locks into the corresponding limiting groove 71 of the limiting seat 7, and the upright frame 2 is locked; then the shelf 3 is flipped upward to the vertical storage state, the shelf 3 is released from the pressure on the inclined arc plate 54, the spring 55 retracts and drives the connecting rod 51 and the connecting rod 52 to reset, the inclined arc plate 54 is reset synchronously along the clearance groove 13, the connecting rod 51 moves in the opposite direction and drives the telescopic rod 44 to swing, driving the rotating plate 43 to rotate in the opposite direction, the slider 422 and the slider 423 of the clamping plate group 42 slide in the opposite direction, the multiple plates 421 synchronously retract inward, the rubber plate 424 tightly adheres to the outer wall of the cable, and the cable bundle is fixed again to prevent the cable from loosening or tangling, and to restore the stable wiring state of the branch box. With the linkage design of the shelf 3 and the linkage mechanism 5, the convenient operation of automatically releasing the cable bundle by flipping the shelf 3 is realized. Combined with the sliding and positioning upright 2, the maintenance efficiency is greatly improved. The snap-fit ​​structure of the limit mechanism 6 and the limit seat 7 ensures the operational stability of the upright 2. Overall, it fully meets the safe and efficient operation and maintenance needs of low-voltage power distribution scenarios.

[0025] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
