[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A power distribution control cabinet for easy maintenance includes a cabinet body 1. An inspection port 11 is provided on one side of the cabinet body 1, and a cabinet door 12 is rotatably connected inside the inspection port 11. A connecting mechanism 2 is provided inside the cabinet body 1, and a mounting plate 13 is provided at one end of the connecting mechanism 2. Components 14 are mounted on the mounting plate 13, and fixing components 3 are provided on both sides of the mounting plate 13. In this invention, the mounting plate 13 can be easily moved from inside the cabinet body 1 to the outside of the cabinet body 1 through the connecting mechanism 2, making it easier for maintenance personnel to install and remove components 14. Simultaneously, the fixing components 3 are used to fix the mounting plate 13, preventing it from moving due to vibration or other external factors, thus affecting the normal operation of components 14. Furthermore, the fixing components 3 also help prevent accidental movement of the mounting plate 13 during component installation, ensuring operational stability and safety.

[0024] The connecting mechanism 2 includes a mounting base 21, of which there are at least four. A folding rod 22 is rotatably connected to the mounting base 21. The folding rod 22 is composed of two connecting rods with their ends pinned together. One end of the folding rod 22 is rotatably connected to a connecting seat 23. In this utility model, the installation plate 13 can be moved within the cabinet 1 by stretching or folding the folding rod 22, thereby facilitating the installation and disassembly of the installation plate 13.

[0025] Furthermore, the mounting plate 13 is provided with at least four positioning holes, and one end of the connecting seat 23 is provided with an insert block 24. One end of the insert block 24 is inserted into the positioning hole. The insert block 24 is provided with a mounting groove. Two wedge blocks 25 are slidably connected in the mounting groove. A spring 26 is provided between the two wedge blocks 25. One side of the wedge block 25 is engaged with the mounting plate 13. In this utility model, the spring force of the spring 26 pushes the wedge block 25, so that one side of the wedge block 25 is engaged with the mounting plate 13 to fix the mounting plate 13. When it is necessary to disassemble the mounting plate 13, the wedge block 25 is pressed to separate one side of the wedge block 25 from the positioning hole, so that the mounting plate 13 can be disassembled.

[0026] Furthermore, the fixing component 3 includes four fixing blocks 31, which are fixedly connected to the cabinet 1. A fixing hole is provided on one side of each fixing block 31. The mounting plate 13 is provided with four mounting holes. A locking block 32 is slidably connected in the mounting holes. Two locking blocks 32 are connected by a handle 33. A pressure spring 34 is provided at one end of each locking block 32. In this utility model, the fixing block 31 is divided into an outer fixing block and an inner fixing block. When the mounting plate 13 is located inside the cabinet 1, the locking block 32 engages with the fixing hole on the inner fixing block. When the mounting plate 13 is located outside the cabinet, the locking block 32 engages with the fixing hole on the outer fixing block. By pulling the handle 33, the locking block 32 can be separated from the fixing hole.

[0027] The cabinet 1 has two sockets 15 on its inner wall and two plugs 16 on one side of the mounting plate 13. One end of each plug 16 is inserted into a socket 15. The bottom of the socket 15 and the bottom of each plug 16 are respectively provided with metal plates. The two metal plates are in contact with each other. In this invention, when the mounting plate 13 is detached from the inner fixing component 3, the power supply is immediately cut off to ensure the safety of the system. By separating the plug 16 from the socket 15, the metal plates break, which can quickly cut off the circuit and prevent short circuits or other safety hazards caused by the detachment of the mounting plate 13. This improves the safety of the entire system and protects the components 14 and the safety of the operators.

[0028] In addition, a push-out spring 17 is fixedly connected to the inner wall of the cabinet 1. One end of the push-out spring 17 abuts against the mounting plate 13. In this utility model, when the mounting plate 13 is released from its fixed position, the push-out spring 17 can quickly push the mounting plate 13 away from its fixed position. At this time, the plug 16 is separated from the socket 15, thereby improving safety and operating efficiency.

[0029] Furthermore, the lower end of the inspection port 11 is provided with a threaded hole 111, and a bolt 112 is internally threaded into the threaded hole 111. A knob 113 is provided at one end of the bolt 112. The bolt 112 is used to fix the cabinet door 12. In this utility model, when the cabinet door 12 is opened, the bolt 112 is rotated by rotating the knob 113 to fix the cabinet door 12, preventing the cabinet door 12 from being unstable during maintenance and affecting maintenance.

[0030] Operating mode: During operation, when maintenance is required, pulling the handle 33 allows the locking block 32 to separate from the fixing hole, and the mounting plate 13 can be pulled. By stretching or folding the folding rod 22, the mounting plate 13 can be moved within the cabinet 1, facilitating the installation and removal of the mounting plate 13. When the mounting plate 13 is released from its fixed position, the push-out spring 17 can quickly push the mounting plate 13 away from its fixed position. At this time, the plug 16 separates from the socket 15, the metal piece breaks, and the circuit can be quickly cut off to prevent short circuits or other safety hazards caused by the mounting plate 13 detaching, thereby improving the safety of the entire system and protecting the safety of components 14 and operators, thus improving safety and operating efficiency. The spring force of the spring 26 pushes the wedge block 25, causing one side of the wedge block 25 to engage with the mounting plate 13 to fix the mounting plate 13. When it is necessary to remove the mounting plate 13, pressing the wedge block 25 separates one side of the wedge block 25 from the positioning hole, allowing the mounting plate 13 to be removed.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
