Description

Technical Field

[0001] This utility model belongs to the technical field of power transmission and distribution cabinets, and in particular relates to a power transmission and distribution cabinet that is easy to maintain. Background Technology

[0002] The central cabinet of a power transmission and distribution cabinet is a key device for power distribution and control, playing a vital role in the power system. However, traditional power transmission and distribution cabinet central cabinets have many inconveniences in terms of maintenance.

[0003] The current method of fixing the cabinet door of the central control cabinet is usually quite complicated, often relying on a variety of tools to tighten bolts or disassemble or install other mechanical parts. The operation steps are cumbersome, and maintenance personnel need to spend a lot of time on the disassembly and installation of the cabinet door during maintenance, which affects maintenance efficiency and maintenance time. Utility Model Content

[0004] The purpose of this utility model is to provide a power transmission and distribution cabinet that is easy to maintain. By setting a limiting component, specifically, rotating the rotating plate drives the compression block to rotate, the compression slide rod slides along the sliding sleeve and compresses the first spring, and the other end of the slide rod is inserted into the locking groove to complete the fixation of the cabinet door to the central cabinet. When the slide rod reaches its maximum stroke, the second spring pushes the top ball to lock into the positioning groove on the rotating plate. The damping rod inside the second spring inhibits the spring movement, realizing the limiting of the rotating plate and preventing the cabinet door from unlocking automatically. Rotating the rotating plate in the opposite direction can release the slide rod, and the first spring resets and drives the slide rod out of the locking groove, completing the quick disassembly of the cabinet door. No tools are required; simply rotating the rotating plate can unlock or lock it, eliminating the traditional cumbersome steps and quickly opening the maintenance channel. After maintenance, rotating in the opposite direction can fix it. No precise alignment or repeated debugging is required, and repeated operations are still highly efficient, significantly shortening the maintenance time of the control module. It solves the problem that the fixing method of the existing central cabinet door is usually more complicated, often relying on multiple tools to tighten bolts or disassemble or assemble other mechanical parts. The operation steps are cumbersome, and maintenance personnel need to spend a lot of time on the disassembly and installation of the cabinet door during maintenance, which affects maintenance efficiency and maintenance time.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a limiting component. Specifically, rotating the rotating plate causes the extrusion block to rotate, and the extrusion slide rod slides along the sliding sleeve and compresses the first spring. The other end of the slide rod is inserted into the locking groove to fix the cabinet door to the central cabinet. When the slide rod reaches its maximum stroke, the second spring pushes the top ball into the positioning groove on the rotating plate. The damping rod inside the second spring inhibits the spring movement, thereby limiting the rotating plate and preventing the cabinet door from unlocking automatically. Rotating the rotating plate in the opposite direction releases the slide rod, and the first spring resets, causing the slide rod to exit the locking groove, completing the quick disassembly of the cabinet door. No tools are required; simply rotating the rotating plate is enough to unlock or lock the door, eliminating the traditional cumbersome steps and quickly opening the maintenance channel. After maintenance, rotating in the opposite direction fixes the door. No precise alignment or repeated adjustments are required, and repeated operations remain highly efficient, significantly shortening the maintenance time of the control module.

[0017] 2. This utility model, through the setting of a fixing component, specifically involves holding the filter handle and pressing the pressing rod, squeezing the opening on the pin fixed to the bottom of the heat dissipation filter against the locking block on the pressing rod, causing the locking block to retract into the pin, allowing the heat dissipation filter to be directly pulled out of the bracket for removal. Alternatively, by holding the pressing rod and aligning the pin with the slot on the bracket, and then releasing it, spring three drives the pressing rod to return to its original position, while spring four drives the sliding rod two to push out the locking block. A limiting block limits the sliding rod two, ensuring the locking block is firmly engaged in the slot, thus completing the rapid installation of the heat dissipation filter. This achieves tool-free quick installation and removal of the filter, with the spring automatically driving the locking block to lock, eliminating the need for precise alignment. Repeated disassembly and assembly during regular maintenance remains highly efficient, significantly shortening the maintenance time for cleaning and replacing the distribution box filter. The simple operation logic reduces the difficulty of operation for maintenance personnel.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] Inside the left-side pressing rod 231, there are two sliding rods 236 on both the left and right sides. The corresponding sides of the two sliding rods 236 pass through the partitions on the left and right sides of the pressing rod 231 and are slidably connected. The corresponding sides of the two sliding rods 236 are fixedly connected to limit blocks 238.

[0040] The left and right sides of the pressing rod 231 are connected to locking blocks 235 by pins. The outer surfaces of the two locking blocks 235 are in contact with the inner surfaces of the openings on the pins 233. The two sliding rods 236 are slidably connected to the locking blocks 235 on opposite sides. The two locking blocks 235 limit the movement of the pressing rod 231.

[0041] The positioning component includes a positioning groove 229 formed on the back of the rotating plate 222. The inner wall of the positioning groove 229 is in contact with the outer surface of the four top balls 228. The inner wall of the positioning groove 229 is provided with four positioning points.

[0042] A specific application of this embodiment is as follows: When repairing the control module 114 of the distribution box 111, the operator first holds the handle of the rotating plate 222 and rotates it inward or outward. The rotating plate 222 drives the rotating shaft 223 to rotate, which in turn drives the pressing block 224 to rotate. When the pressing block 224 rotates, its outer surface gradually presses the slide rod 212 until the slide rod 212 is pressed to its four corners. During the pressing process, the slide rod 212 slides along the direction of the sliding sleeve 214. The spring 215 sleeved on the slide rod 212 applies a reverse force to the slide rod 212. When the slide rod 212 is pressed to its maximum stroke, its other end is inserted into the locking groove 216 to complete the fixation of the cabinet door 113 and the central cabinet 112. At the same time, when the slide rod 212 reaches its maximum stroke, the spring 227 pushes the top ball 228 to engage with the rotating plate 222. The positioning point of the upper positioning groove 229; the damping rod 226 inside the second spring 227 will suppress the movement of the second spring 227, thereby limiting the rotation plate 222 and indirectly limiting the displacement of the squeezing block 224, ensuring that the cabinet door 113 will not be automatically unlocked after being fixed to the central cabinet 112. When the fixation is released, the cabinet door 113 can be quickly disassembled by simply rotating the rotation plate 222. The quick disassembly design allows the cabinet door 113 to be unlocked by simply rotating the rotation plate 222 when the control module 114 is being repaired without tools, eliminating the tedious steps of screwing and disassembling the connecting parts in the traditional structure, and quickly opening the inspection channel. After the control module 114 is repaired, the control module 114 can be fixed by simply rotating the rotation plate 222 in the opposite direction. There is no need for precise alignment or repeated debugging. Repeated operations are still convenient and efficient, reducing the downtime of the control module 114 for maintenance.

[0043] Then, when maintaining the heat dissipation filter 116 of the distribution box 111, hold the filter handle and press the pressing rod 231 to move it downwards. At the same time, the opening on the pin 233 fixed at the bottom of the heat dissipation filter 116 will squeeze the locking block 235 on the pressing rod 231, causing the locking block to retract into the pin 233. While holding the pressing rod 231, pull the heat dissipation filter 116 out of the bracket 115 for quick removal. When reinstalling, hold the pressing rod 231, align the pin 233 with the slot 232 on the bracket 115, insert it, and then release the pressing rod. The third spring 234 pushes the pressing rod 231 upward to reset, while the fourth spring 237 drives the slide rod 236 to push out the locking block 235. The limiting block 238 limits the slide rod 236 to ensure that the locking block 235 is firmly locked into the slot 232, completing the quick installation of the heat dissipation filter and realizing quick installation and removal of the filter. During installation, you only need to "insert the filter and release the pressing rod". The spring automatically drives the locking block to lock. There is no need for precise alignment or repeated adjustment. The reset is completed instantly. If regular maintenance is required, repeated disassembly and assembly are still highly efficient, which greatly shortens the filter maintenance time of the distribution box. The operation logic is simple.
