Description

Technical Field

[0001] This utility model relates to the field of self-locking technology for power distribution cabinet installation, specifically to a self-locking structure for intelligent power distribution cabinets. Background Technology

[0002] Distribution cabinets are devices for unified power management. They are divided into outdoor and indoor types, and the installation requirements vary depending on the environment. Chinese Patent CN211879819U discloses a self-locking outdoor energy-saving high-voltage distribution cabinet, including a distribution cabinet, a support plate, and a fixing plate. A partition plate is fixed inside the distribution cabinet. The support plate is fixed to the bottom of the distribution cabinet. A movable cylinder is movably passed through the inner bottom surface of the base box, and a gear is sleeved on the outer side of the movable cylinder. The fixing plate is fixed to the base box next to the gear. An adjusting rod is passed through the inside of the movable cylinder, and a limit rod is fixed to the top of the adjusting rod. A second through groove is opened on the base box outside the adjusting rod. A guide block is fixed to the bottom of the adjusting rod, and a movable rod is movably arranged on the side of the guide block. A spring is wound around the outer side of the movable rod. This outdoor energy-saving high-voltage distribution cabinet features a self-locking bottom. After installation, the cabinet's bottom is self-locking, increasing installation convenience. Furthermore, the self-locking mechanism prevents damage to the cabinet's fixed structure, ensuring its stability.

[0003] The existing technology has the following shortcomings: In the existing technology, when locking the distribution cabinet and the base box, the distribution cabinet needs to be pushed to rotate the movable cylinder through the meshing of the gear and toothed block, causing the guide block to descend and contact the movable rod, thus locking the movable rod in the limiting groove. This operation is relatively cumbersome; furthermore, the fixed height of the base box makes adjustment inconvenient. Therefore, a self-locking structure for intelligent distribution cabinets is provided to solve the above problems. Utility Model Content
