DETAILED DESCRIPTION

[0018] 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.

[0019] Reference Figure 1-3A spliced ​​power distribution cabinet comprises a cabinet 1, feet 2 installed at four corners of the lower surface of the cabinet 1, and a connecting device, wherein the front side of the cabinet 1 is provided with a cabinet door 12, and the cabinet door 12 is provided with a handle 13, and the upper ends of the two side walls of the cabinet 1 are provided with vents 11, and the rear side of the cabinet 1 is provided with a dustproof net 14, and the connecting device comprises a connecting rod 3 and a first connecting column 31, and the central position of the connecting rod 3 away from the cabinet 1 is provided with a threaded groove 35, and the four corners of the side of the connecting rod 3 away from the cabinet 1 are provided. A positioning column 34 is provided, a rotating rod 32 is sleeved on the side of the first connecting column 31 away from the cabinet 1, and the other end of the rotating rod 32 is sleeved on the second connecting column 33, and the rotating rod 32 is connected to the first connecting column 31 and the second connecting column 33 through a fixing block 321, and a screw rod 36 is provided inside the first connecting column 31, the second connecting column 33 and the rotating rod 32, and the rotating rod 32 and the screw rod 36 are threadedly connected, and positioning holes 331 are provided at the four corners of the side of the second connecting column 33 away from the cabinet 1.

[0020] When in use, first place the cabinet 1 in the corresponding position, align the second connecting column 33 on the cabinet 1 with the connecting rod 3, insert the positioning column 34 on the connecting rod 3 into the positioning hole 331 on the second connecting column 33, and then rotate the rotating rod 32 to drive the screw rod 36 to rotate, and thread the screw rod 36 with the threaded groove 35 on the connecting rod 3 to splice the two distribution cabinets. According to the above method, multiple distribution cabinets can be spliced. A spacing is left between each two distribution cabinets to dissipate heat through the vents 11 to avoid the two adjacent distribution cabinets being too close to each other and affecting the heat dissipation effect. A heat dissipation fan is provided on the rear side of the cabinet 1, which can actively dissipate heat when the temperature is high. A dustproof net 14 is provided on the outside to effectively prevent mosquitoes, sand and stones from entering the cabinet 1 and reduce damage to internal electronic components.

[0021] The screw rod 36 is threadedly connected to the thread groove 35 on the connecting rod 3, which is convenient for fixing the two distribution cabinets, and the installation is simple and fast.
