[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1 - Figure 5 The utility model provides a technical solution: a drawer plug-in for a power distribution cabinet, comprising a main body 1, the main body 1 comprising a plug-in upper plate 2 and a plug-in lower plate 3, and the plug-in lower plate 3 is installed directly below the plug-in upper plate 2, a positioning strip 4 is fixedly provided at the end of the inner wall of the plug-in upper plate 2, a positioning groove 5 is provided on the surface of the positioning strip 4, a through groove 8 is provided at the end of the inner wall of the plug-in lower plate 3, an L-shaped card strip 6 is movably installed in the through groove 8, and a hook block 7 is fixedly provided at one end of the L-shaped card strip 6 located on the inner side of the plug-in lower plate 3, and the hook block 7 corresponds to the positioning groove 5. Through the coordination of the positioning strip 4 and the L-shaped card strip 6, the connection structure is simple and the operation is convenient, the plug-in upper plate 2 and the plug-in lower plate 3 can be quickly installed or removed, which is convenient for the staff to replace and adjust the working components inside the main body 1, thereby improving the work efficiency.

[0021] The inner wall of the through slot 8 is provided with a first limiting slot 10, and the surface of the L-shaped clip 6 is fixedly provided with a first limiting plate 11 matched with the first limiting slot 10, and the surface of the L-shaped clip 6 and the side of the first limiting plate 11 are provided with a spring 9, and the spring 9 and the first limiting plate 11 are movably installed inside the through slot 8 through the first limiting slot 10. This enables the position of the L-shaped clip 6 to be limited, ensuring that the upper plug-in board 2 and the lower plug-in board 3 can be stably matched together, thereby improving the strength of the structure.

[0022] The length of the L-shaped clip 6 extending out of one end of the plug-in lower plate 3 is equal to the depth of the positioning groove 5. When the staff presses the L-shaped clip 6 extending out of one end of the plug-in lower plate 3 into the through groove 8, when the end of the L-shaped clip 6 is parallel to the plug-in lower plate 3, the hook block 7 is completely separated from the positioning groove 5, so that the plug-in upper plate 2 and the plug-in lower plate 3 can be disassembled.

[0023] Two side blocks 13 are fixedly arranged on the surface of the plug-in lower plate 3, and the two side blocks 13 are respectively installed on both sides of the through slot 8, and an L-shaped cover plate 12 is arranged between the two side blocks 13, and the L-shaped cover plate 12 blocks the surface of the L-shaped card strip 6. The L-shaped cover plate 12 can protect the L-shaped card strip 6 to prevent the staff from accidentally touching the L-shaped card strip 6.

[0024] The surface of the side block 13 is provided with a second limiting groove 14, and the bottom of the L-shaped cover plate 12 is provided with a second limiting plate 15 corresponding to the second limiting groove 14, and the second limiting plate 15 is movably installed between the two side blocks 13 through the second limiting groove 14. The second limiting groove 14 can limit the L-shaped cover plate 12, ensuring that the L-shaped cover plate 12 can always cover the surface of the L-shaped clip 6.

[0025] A guide column 16 is fixedly arranged on the surface of the bottom end of the plug-in upper plate 2, and a guide hole 17 matching with the guide column 16 is arranged on the surface of the top end of the plug-in lower plate 3, so as to improve the stability and installation accuracy of the connection between the plug-in upper plate 2 and the plug-in lower plate 3.

[0026] Working principle: first, the positioning strip 4 cooperates with the L-shaped card strip 6, and the hook block 7 is clamped in the inside of the positioning groove 5. The positioning strip 4 and the L-shaped card strip 6 can be stably connected together, so that the plug-in upper plate 2 and the plug-in lower plate 3 can be fixedly installed together. Then the staff presses the L-shaped card strip 6 extending out of one end of the plug-in lower plate 3 into the through groove 8. When the end of the L-shaped card strip 6 is parallel to the plug-in lower plate 3, the hook block 7 is completely separated from the positioning groove 5, so that the plug-in upper plate 2 and the plug-in lower plate 3 can be disassembled. The connection structure is simple and the operation is convenient. The plug-in upper plate 2 and the plug-in lower plate 3 can be quickly installed or removed, which is convenient for the staff to replace and adjust the working components inside the main body 1, thereby improving work efficiency.

[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
