[0002] Distribution cabinets are key equipment in power systems, used to distribute electrical energy from high-voltage grids or substations to low-voltage users or equipment. Their main functions include power distribution, protection of circuits and equipment (via circuit breakers, residual current devices, etc.), integrated control devices for easy equipment start-up and monitoring, real-time monitoring of parameters such as current, voltage, and power, and ensuring the safety of operators and equipment. Distribution cabinets are widely used in industrial, commercial, building, and residential applications, and their structure and configuration can vary depending on different needs, including switch cabinets, busbar trunking, and power distribution equipment.

[0003] During routine maintenance, some existing power distribution cabinets require the cabinet doors to be opened, and electrical components are installed on the doors. Since the maintenance personnel are inside the cabinet doors during the maintenance process, if the cabinet doors move due to external force, the personnel may come into contact with the exposed ends of the electrical components, thereby endangering communication security and personal safety. Therefore, this problem needs to be solved. Utility Model Content

An inspection port 203 is provided on one side of the support frame 201, through which the cabinet door 101 can be inspected. The electrical components 102 on the cabinet are inspected and maintained. The support frame 201 has two T-shaped grooves 204 symmetrically opened on the side surface near the inspection port 203. T-shaped plates 206 are slidably connected inside the two T-shaped grooves 204. The same baffle 2 is fixedly connected to the side surface of the two T-shaped plates 206 away from the cabinet door 101. Limiting holes 205 are opened at both ends of the two T-shaped grooves 204. The two limiting holes 205 are equipped with a constraint mechanism for constraining the baffle 2. By setting the baffle 2 inside the cabinet door 101, the staff can avoid direct contact with the electrical components 102.

[0018] Preferably, the constraint mechanism includes a limiting post 207, which is slidably connected to one side of the baffle 2, and the limiting post 207 and the limiting hole 205 are mutually matched. A pull plate 208 is fixedly connected to the surface of the limiting post 207 away from the limiting hole 205. A tension spring 209 is sleeved on the surface of the limiting post 207 near the pull plate 208. One end of the tension spring 209 is fixedly connected to one side of the pull plate 208, and the other end of the tension spring 209 is fixedly connected to one side of the inside of the baffle 2. A fixing frame 302 is fixedly connected to one side of the support frame 201. The fixing frame 302 is provided with a fixing mechanism for fixing the cabinet door 101. The baffle 2 can be constrained by the setting of the limiting post 207.

[0019] Furthermore, the fixing mechanism includes a lead screw 304, which is rotatably connected to the bottom of the fixing frame 302. An adjusting plate 305 is fixedly connected to the bottom of the lead screw 304. A slider 303 is slidably sleeved on the surface of the lead screw 304, and the slider 303 cooperates with the lead screw 304 through a lead screw nut. An adjusting column 306 is slidably connected to the top of the slider 303. The height of the adjusting column 306 can be adjusted by the slider 303. A spring 307 is fixedly connected to the bottom end of the adjusting column 306, and the bottom end of the spring 307 is fixedly connected to the inside of the slider 303. A pressure plate 308 is fixedly sleeved on the surface of the adjusting column 306 away from the lead screw 304. A limiting plate 3 is fixedly connected to the surface of the cabinet 1 near the adjusting column 306. Multiple adjusting holes 301 are opened on the surface of the limiting plate 3, and the multiple adjusting holes 301 are evenly opened in an arc shape. The multiple adjusting holes 301 are all configured to cooperate with the adjusting column 306. The cabinet door 101 can be fixed by the adjusting column 306.

[0020] Working Principle: A support frame 201 is installed inside the cabinet door 101, and the support frame 201 is connected to the cabinet door 101 via a fixing lug 202. An inspection port 203 is provided on one side of the support frame 201, and a baffle 2 is installed on one side of the inspection port 203. The baffle 2 separates the operator from the electrical components 102, preventing direct contact. Two limiting posts 207 are installed on one side of the baffle 2. Initially, the two limiting posts 207 engage with limiting holes 205 on one side of the support frame 201. When the limiting posts 207 are pulled, they can be moved out of the current limiting hole 205, thus opening the baffle 2. Two limiting holes 205 are also provided on the other side of the support frame 201, and these two limiting holes 205 also engage with the limiting posts 207, thereby preventing obstruction. After the panel 2 is opened, it falls off. A fixing bracket 302 is also installed on one side of the support frame 201. After the opening angle of the cabinet door 101 is determined, the lead screw 304 at the bottom of the fixing bracket 302 is rotated. A slider 303 is installed on the surface of the lead screw 304. The slider 303 is engaged with the lead screw 304 through the lead screw nut. When the lead screw 304 is rotated, the slider 303 can be moved upward. An adjusting column 306 is also installed on the top of the slider 303, so that the adjusting column 306 will move upward synchronously. A limit plate 3 is installed on the side of the cabinet 1 near the adjusting column 306. The top of the limit plate 3 has multiple adjusting holes 301. Since the multiple adjusting holes 301 are engaged with the adjusting column 306, as the slider 303 continues to move upward, the adjusting column 306 will enter the adjusting hole 301, thereby preventing the cabinet door 101 from shifting.
