Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to an insulation device for a distribution box. Background Technology

[0002] A distribution cabinet is an electrical device used for centralized control and distribution of electrical energy. It mainly consists of a cabinet, electrical components (such as circuit breakers, contactors, relays, fuses, etc.), busbars, and conductors. There are a large number of electrical components and busbars in the distribution cabinet, which carry charges at different potentials. The insulating board can isolate these live parts from other metal parts or the cabinet, prevent short circuits between conductors at different potentials, avoid serious accidents such as electrical faults, fires, or even explosions caused by short circuits, and ensure the safe and reliable operation of the electrical system.

[0003] In a distribution cabinet, the insulation board is a key component for isolating electrical components from the cabinet. When installing electrical components, multiple mounting brackets are usually fixed on the insulation board, and then the electrical components are installed on the mounting brackets. This process requires drilling multiple mounting screw holes in the insulation board and mounting brackets. The processing of a large number of screw holes can damage the structural integrity of the insulation board and mounting brackets, weakening their mechanical strength. In addition, since the specifications and quantity of electrical components to be installed in the distribution cabinet are uncertain, more electrical components may need to be added later. Once electrical components are added, the number of brackets needs to be increased and the already installed electrical components need to be adjusted. The operation is cumbersome, requiring not only adjustment of the bracket positions, but also disassembly and relocation of the electrical components initially installed on the brackets, and may even require re-drilling holes. To address the above technical pain points, this application proposes an insulation device for a distribution box. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insulation device for a distribution box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an insulation device for a distribution box, including a cabinet, an insulation plate is provided on the back of the cabinet, countersunk holes are provided at the four corners of the front of the insulation plate, and first bolts that are threaded to the inner wall of the cabinet are inserted into the four countersunk holes. Vertical guide rods are installed on both sides of the front of the insulation plate, and an installation mechanism is provided between the two guide rods.

[0006] The mounting mechanism includes a mounting frame, multiple mounting components, and two positioning components. The two positioning components are respectively mounted on both sides of the mounting frame and are respectively sleeved on two guide rods. The side of the mounting frame has a through-slot for movement, and each mounting component is slidably mounted in the slot.

[0007] Optionally, the mounting assembly includes a slider, a connecting plate, and a fourth bolt. The vertical part of the slider is inserted into the moving slot. The connecting plate is located on the rear side of the mounting bracket, and a screw hole is provided at the center of the side of the connecting plate. The front of the slider has a through-hole aligned with the screw hole, and a fourth bolt that can be threaded into the screw hole is inserted through the through-hole. Both ends of the slider near the connecting plate have rod slots. Two positioning rods are fixedly installed on the side of the connecting plate near the slider, which are respectively inserted into the two rod slots. The side walls of the two positioning rods have slots, and a limiting rod passing through the slot is fixedly installed in each of the two rod slots.

[0008] Optionally, the top of the right end of the mounting bracket is provided with a notch that communicates with the moving slot. The top of both sides of the notch is notched, and a matching T-shaped closing plate is fitted into the notch. The top of both ends of the closing plate is inserted with a third bolt that connects to the notch. The width of the notch is greater than the width of the mounting component.

[0009] Optionally, the positioning assembly includes a first clamping plate, a fixed shaft, a second clamping plate, and a nut. The first clamping plate and the fixed shaft are both fixedly installed at the end of the mounting frame. The second clamping plate is rotatably sleeved on the fixed shaft, and the second clamping plate can be flipped around the fixed shaft to fit against the first clamping plate. The sides of the first clamping plate and the second clamping plate that fit against each other are provided with clamping grooves for fitting onto the guide rods. Semi-cylindrical screws are fixedly installed at the ends of the first clamping plate and the second clamping plate away from the mounting frame. The nut can be threaded onto the two screws that are mated together.

[0010] Optionally, a number of slots are equidistantly provided on the front side of the guide rod. A locking block that matches the slot is fixedly installed in the slot on the side of the second clamping plate. The diameter of the slot is the same as the diameter of the guide rod. When the first clamping plate and the second clamping plate are fitted onto the guide rod, the locking block in the slot on the side of the second clamping plate engages in one of the slots on the guide rod.

[0011] Optionally, both ends of the two guide rods are threaded with second bolts, and each second bolt is threaded into the front side of the insulating plate.

[0012] The beneficial effects of this utility model are:

[0013] During installation, the position of the mounting component can be freely adjusted within the moving slot according to the distance between the mounting ears on both sides of the electrical component. Tightening the fourth bolt not only secures the component mounting ears to the slider but also locks the mounting component in position on the mounting bracket. Removing the closing plate allows for the addition or removal of the number of mounting components within the moving slot, facilitating later optimization of the electrical component installation layout. This makes it easier to add electrical components to the mounting bracket. Unlike common mounting modules, which require fixing the mounting mold before installing the electrical component, this mounting component simultaneously secures the electrical component to the slider and fixes the position between the mounting component and the mounting bracket by tightening the fourth bolt. Without tightening the fourth bolt, the position of the electrical component on the mounting bracket can be freely moved, facilitating optimization of the installation layout.

[0014] By utilizing the cooperation of locking blocks and slots, the mounting bracket can be flexibly adjusted and easily disassembled. When the first and second clamping plates are closed, the two screws are tightened with nuts. At this time, the locking blocks on the second clamping plate will engage with the slots on the guide rod, constraining the movement of the second clamping plate on the guide rod, thereby fixing the position of the mounting bracket. If it is necessary to adjust the height of the mounting bracket on the guide rod, simply unscrew the nuts to separate the first and second clamping plates, allowing the locking blocks to disengage from the slots and easily achieve disassembly. Conversely, installation can also be completed through the same operation. The positioning component not only ensures that the position of the mounting bracket on the guide rod can be freely adjusted, but also greatly simplifies the disassembly and assembly process of the mounting bracket, significantly improving the convenience of operation and installation efficiency.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-7 This utility model provides a technical solution: an insulation device for a distribution box, including a cabinet 1, an insulation plate 2 is provided on the back of the cabinet 1, countersunk holes 3 are provided at the four corners of the front of the insulation plate 2, and first bolts 4 that are threaded to the inner wall of the cabinet 1 are inserted into the four countersunk holes 3. Vertical guide rods 5 are installed on both sides of the front of the insulation plate 2, and an installation mechanism 7 is provided between two guide rods 5. The two guide rods 5 can provide an installation position for the installation mechanism 7.

[0026] The mounting mechanism 7 includes a mounting frame 71, multiple mounting components 8, and two positioning components 9. The two positioning components 9 are respectively mounted on both sides of the mounting frame 71 and are respectively sleeved on two guide rods 5. The side of the mounting frame 71 has a through-slot 72. Each mounting component 8 is slidably mounted in the through-slot 72. The insulating plate 2, the mounting frame 71, the mounting components 8, the positioning components 9, and the guide rods 5 are all made of epoxy resin reinforced with glass fiber and carbon fiber, formed by pultrusion process. It has high hardness, can withstand large mechanical stress, and has excellent insulation performance.

[0027] like Figure 4 and Figure 5As shown, the mounting assembly 8 includes a slider 81, a connecting plate 82, and a fourth bolt 83. The vertical part of the slider 81 is inserted into the moving groove 72. The connecting plate 82 is located on the rear side of the mounting bracket 71, and a screw hole 88 is provided at the center of the side of the connecting plate 82. A through-hole aligned with the screw hole 88 is provided on the front of the slider 81, and a fourth bolt 83 that can be threaded into the screw hole 88 is inserted through the through-hole. Rod grooves 84 are provided at both ends of the slider 81 near the connecting plate 82. Two positioning rods 85 are fixedly installed on the side of the connecting plate 82 near the slider 81, respectively inserted into the two rod grooves 84. A slot 87 is provided on the side wall of each of the two positioning rods 85, and a limiting rod 86 passing through the slot 87 is fixedly installed in each of the two rod grooves 84. Inserted into the slot 85, it prevents the positioning rod 85 from detaching from the rod slot 84. When installing electrical components, the two mounting components 8 in the moving slot 72 are positioned by the lugs on both sides of the electrical components. Then, the fourth bolt 83 is used to pass through the lugs on the side of the electrical components and the through holes on the slider 81, and is threadedly connected to the screw hole 88 on the connecting plate 82. Since the two positioning rods 85 are constrained by the rod slot 84, the connecting plate 82 cannot rotate. Therefore, as the fourth bolt 83 rotates with the screw hole 88, it can gradually move the connecting plate 82 closer to the back of the mounting bracket 71. Finally, the connecting plate 82 will press tightly against the back of the mounting bracket 71. Through the cooperation and pressing of the connecting plate 82 and the slider 81, the position of the mounting component 8 is fixed.

[0028] like Figure 4 and Figure 6 As shown, the top of the right end of the mounting bracket 71 has a notch that communicates with the moving slot 72. There are notches 74 on the top of both sides of the notch, and a matching T-shaped closing plate 73 is fitted into the notch. The top of both ends of the closing plate 73 is inserted with a third bolt 75 that connects to the notch 74. The width of the notch is greater than the width of the mounting component 8. When there are too many or too few mounting components 8 in the moving slot 72 on the mounting bracket 71, the third bolt 75 is unscrewed and the closing plate 73 is removed. Then the mounting component 8 can be taken out or put in through the notch at the right end of the mounting bracket 71. Thus, the mounting components 8 on the mounting bracket 71 can be appropriately increased or decreased according to the number of electrical components installed.

[0029] like Figure 4 and Figure 7As shown, the positioning assembly 9 includes a first clamping plate 91, a fixed shaft 92, a second clamping plate 93, and a nut 95. The first clamping plate 91 and the fixed shaft 92 are both fixedly installed at the ends of the mounting bracket 71. The second clamping plate 93 is rotatably sleeved on the fixed shaft 92, and the second clamping plate 93 can be flipped around the fixed shaft 92 to fit against the first clamping plate 91. The sides of the first clamping plate 91 and the second clamping plate 93 that fit against each other are provided with clamping grooves for fitting onto the guide rods 5. Semi-cylindrical screws 94 are fixedly installed at the ends of the first clamping plate 91 and the second clamping plate 93 that are away from the mounting bracket 71. The nut 95 can be threaded onto the two screws 94 that are mated together. The positioning assembly 9 not only allows the position of the mounting bracket 71 on the two guide rods 5 to be freely adjusted, but also facilitates the disassembly and assembly of the mounting bracket 71 on the guide rods 5.

[0030] like Figure 3 and Figure 7 As shown, several slots 51 are equidistantly provided on the front side of the guide rod 5. A locking block 96 adapted to the slot 51 is fixedly installed in the slot on the side of the second clamping plate 93. The diameter of the slot is the same as the diameter of the guide rod 5. When the first clamping plate 91 and the second clamping plate 93 are fitted onto the guide rod 5, the locking block 96 in the slot on the side of the second clamping plate 93 engages in one of the slots 51 on the guide rod 5. Through the mutual engagement of the locking block 96 and the slot 51, after the first clamping plate 91 and the second clamping plate 93 are closed, the second clamping plate 93 is constrained by the slot 51 and cannot move on the guide rod 5. Thus, the position height of the mounting bracket 71 on the guide rod 5 can be freely adjusted. After unscrewing the nut 95, the first clamping plate 91 and the second clamping plate 93 can be separated, and the locking block 96 can be separated from the slot 51. In this way, the mounting bracket 71 can be removed from the two guide rods 5. Similarly, more mounting mechanisms 7 can be installed on the guide rod 5 as needed.

[0031] like Figure 2 and Figure 3 As shown, both ends of the two guide rods 5 are connected to a second bolt 6, and each second bolt 6 is threaded into the front side of the insulating plate 2. The two ends of the guide rod 5 can be fixedly installed on the insulating plate 2 by means of the second bolt 6, thereby realizing the position fixation of the guide rod 5.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
