The outer side wall of the mounting brackets is provided with a sliding groove that connects to the installation opening. A sliding plate is slidably provided on the inner side of the sliding groove.

[0004] The above-disclosed patent still has the following technical defects: the above solution uses the left and right ends to clamp the cable between the two clamps. However, since the cable cannot be guaranteed to be arranged vertically when it is inserted into the switch cabinet, the cable may also be distributed along an L-shaped path. The above-mentioned limiting structure can only fix the vertical part of the cable and cannot fix the horizontal part of the cable. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a wiring structure for a high-voltage switchgear.

[0006] The technical solution of this utility model is a wiring structure for a high-voltage switchgear, including multiple wiring frame mechanisms. These multiple wiring frame mechanisms are all installed inside the high-voltage switchgear. Each wiring frame mechanism includes an elastic telescopic rod assembly and multiple sets of clamping assemblies. The elastic telescopic rod assembly includes a wire frame and two movable insert rods, which are slidably installed at both ends of the wire frame. A first elastic connecting assembly connects the wire frame to each of the two movable insert rods. Multiple slots are provided at both ends of the inner wall of the high-voltage switchgear for the ends of the movable insert rods to be inserted. Multiple sets of clamping assemblies are arranged side-by-side. Each clamping assembly includes a movable clamping plate, a fixed clamping plate, and a second elastic connecting assembly. The fixed clamping plate is fixedly connected to the wire frame, and the movable clamping plate is slidably installed on the wire frame. The movable clamping plate is connected to the wire frame via the second elastic connecting assembly.

[0007] Preferably, the movable clamping plate and the fixed clamping plate form a ring structure, and the first lever is connected to the outer wall of the movable clamping plate.

[0008] Preferably, both the movable clamping plate and the fixed clamping plate have sponge on their inner walls.

[0009] Preferably, the cross-section of the movable insertion rod is square.

[0010] Preferably, the first elastic connection component includes a first spring, and first grooves are provided at both ends of the wire frame. One end of the movable plug rod is movably disposed in the first groove and connected to the limiting slider. The limiting slider is slidably installed in the first groove, and the first spring is disposed in the first groove. A second lever is connected to the movable plug rod.

[0011] Preferably, the second elastic connection assembly includes a guide rod and a second spring. A connecting slider is connected to the movable clamping plate. Multiple second slide grooves are provided on the wire frame for the connecting slider to slide. The guide rod is installed in the corresponding second slide groove. The connecting slider is slidably mounted on the guide rod. The second spring is sleeved and installed on the guide rod.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] 1. By setting up multiple cabling rack mechanisms, multiple cables can be fixed simultaneously. The cabling rack mechanism can be adjusted to adapt to the cable routing, so that multiple cables are arranged in an orderly manner, and it is not easy for them to get tangled. It also facilitates subsequent cable maintenance.

[0014] 2. By setting up the elastic telescopic rod assembly, the wiring rack mechanism can be quickly disassembled and assembled. No screws or other fasteners are needed during the disassembly and assembly process, which has the advantages of simplified structure and high disassembly and assembly efficiency.

[0020] Example 1

[0021] like Figures 1-4 As shown, this embodiment proposes a high-voltage switchgear wiring structure, including multiple wiring frame mechanisms; all multiple wiring frame mechanisms are installed inside the high-voltage switchgear 1; the wiring frame mechanism includes an elastic telescopic rod assembly and multiple sets of clamping assemblies; the elastic telescopic rod assembly includes a wire frame 2 and two movable plug rods 3, the two movable plug rods 3 are slidably installed at both ends of the wire frame 2, and a first elastic connection assembly is connected between the wire frame 2 and the two movable plug rods 3, the first elastic connection assembly including a first spring 8, a first sliding groove 201 is opened at both ends of the wire frame 2, one end of the movable plug rod 3 is movably disposed in the first sliding groove 201 and connected to a limiting slider 9, the limiting slider 9 is slidably installed in the first sliding groove 201, the first spring 8 is disposed in the first sliding groove 201; a second lever is connected to the movable plug rod 3. Block 7, both ends of the inner wall of the high-voltage switchgear 1 are provided with multiple slots for the ends of the movable plug rod 3 to be inserted; multiple clamping assemblies are arranged side by side, the clamping assemblies include a movable clamping plate 41, a fixed clamping plate 42 and a second elastic connecting assembly, the fixed clamping plate 42 is fixedly connected to the wire frame 2, the movable clamping plate 41 is slidably mounted on the wire frame 2, the movable clamping plate 41 and the wire frame 2 are connected by the second elastic connecting assembly, the second elastic connecting assembly includes a guide rod 10 and a second spring 11, a connecting slider is connected to the movable clamping plate 41, the wire frame 2 is provided with multiple second sliding grooves 202 for the connecting slider to slide, the guide rod 10 is installed in the corresponding side second sliding groove 202, the connecting slider is slidably mounted on the guide rod 10, and the second spring 11 is sleeved and mounted on the guide rod 10.

[0022] In this embodiment, the appropriate number of wiring rack mechanisms is selected according to the wiring length of the cable inside the high-voltage switchgear 1, so that multiple wiring rack mechanisms are arranged along the direction of the cable.

[0023] When installing the wiring rack mechanism, the second levers 7 at both ends of the elastic telescopic rod assembly are simultaneously pressed towards the middle, causing the elastic telescopic rod assembly to retract to its shortest length. Then, the wiring rack mechanism is moved into the interior of the high-voltage switchgear 1. When the wiring rack mechanism is moved to the designated installation position and its two ends are aligned with the corresponding slots, the two second levers 7 are released. Under the elastic force of the first springs 8 on both sides, the movable plug 3 is driven to reset, causing the end of the movable plug 3 to engage with the corresponding slot. This achieves the fixed installation of the wiring rack mechanism. In summary, by setting the above-mentioned elastic telescopic rod assembly, the wiring rack mechanism can be quickly disassembled and assembled without the need for screws or other fasteners during disassembly and assembly, which has the advantages of simplified structure and high disassembly and assembly efficiency.

[0024] When clamping the cable, manually move the first lever 5 to separate the movable clamping plate 41 from the fixed clamping plate 42, then place the cable between the movable clamping plate 41 and the fixed clamping plate 42. Finally, release the first lever 5, and the movable clamping plate 41 will automatically reset under the elastic force of the second spring 11, thus limiting the cable between the movable clamping plate 41 and the fixed clamping plate 42. This arrangement makes multiple cables neatly arranged, less prone to knotting and tangling, and also facilitates subsequent cable maintenance.

[0025] Example 2

[0026] like Figure 4 As shown in the figure, the high-voltage switchgear wiring structure proposed in this embodiment, compared with the first embodiment, in this embodiment, the movable clamping plate 41 and the fixed clamping plate 42 form a ring structure, and the first lever block 5 is connected to the outer wall of the movable clamping plate 41; the inner walls of the movable clamping plate 41 and the fixed clamping plate 42 are both provided with sponge 6; in this embodiment, the sponge 6 is used to clamp the surface of the cable to prevent the cable from loosening, and since the sponge 6 is a flexible material, it can achieve flexible clamping of the cable surface.

[0027] Example 3

[0028] like Figure 3 As shown, this embodiment proposes a high-voltage switchgear wiring structure. Compared with Embodiment 1, in this embodiment, the cross-section of the movable plug rod 3 is a square structure. Through the above structure, the installation of the elastic telescopic rod assembly can be realized in four directions. However, the installation positions used in this technical solution are only two: placing the clamping assembly in front of the elastic telescopic rod assembly and placing the clamping assembly above the elastic telescopic rod assembly. It should be added that when fixing the vertical part of the cable, the clamping assembly on the wiring frame mechanism should be placed in front of the elastic telescopic rod assembly, while for the horizontal part of the cable, the clamping assembly can be placed below the telescopic rod assembly.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
