[0002] The electrical cabinet is a metal cabinet for storing electrical components. A locking mechanism is arranged between the cabinet door and the cabinet body to ensure that the cabinet door is closed and the electrical cabinet is in a sealed state, preventing unauthorized personnel from accidentally touching the components and causing damage or electrical hazards.

[0003] A locking mechanism for an electrical cabinet is disclosed in Chinese Utility Model Patent No. CN213367087U with a filing date of September 21, 2020. The patent belongs to the field of electrical cabinets and its technical solution points include a clamping block fixedly connected to the cabinet door and two fixed blocks fixedly connected to the side wall of the electrical cabinet body. The two fixed blocks are arranged in parallel, and a clamping rod is provided on the fixed block. The clamping rod is vertically arranged and slides through the fixed block and is arranged inside the fixed block. A clamping groove is formed on the top and bottom side surfaces of the clamping block. When the cabinet door is closed, the clamping block is located between the two fixed blocks, and the clamping rod is inserted into the clamping groove. A fixed plate is fixedly connected to the top end surface of the clamping rod. A compression spring is arranged between the fixed plate and the fixed block. The compression spring is sleeved on the clamping rod. A limiting plate is rotatably connected to the fixed plate. When the cabinet door is locked, the limiting plate is located at the fixed plate and is in contact with the fixed plate. The utility model makes it convenient to remove the clamping rod, making it easier to separate the cabinet door and the electrical cabinet body.

[0004] In this technical solution, the cabinet door and the electrical cabinet body are locked by inserting the clamping rod into the clamping groove. However, in daily use, the cabinet door may collide with the cabinet body when closed. Over time, the connecting parts between the cabinet door and the cabinet body may become loose, making it difficult to align the clamping rod and the clamping groove. Therefore, the position of the clamping block needs to be adjusted every time the door is closed to align the clamping groove with the clamping rod. However, due to the loosening of the connecting parts, a gap may appear between the cabinet door and the cabinet body when the clamping groove and the clamping rod are aligned. Therefore, further improvement is needed. UTILITY MODEL CONTENTS
