Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figures 1-3, an easy-to-install and easy-to-disassemble power supply casing includes a lower casing 1 and an upper casing 9, the upper casing 9 is located above the top of the lower casing 1, and the lower casing 1 and the upper casing 9 pass through A plurality of locking devices are fixed together, and the locking device includes a projection 8 installed on the bottom of the upper casing 9 and a slot 2 arranged on the top of the lower casing 1, and the side of the lower casing 1 near the slot 2 is provided with a The slot 2 is connected to the socket 3, and the socket 3 is slidably installed with a fixed column 4, and one end of the fixed column 4 is connected with a column cap 5, and the column cap 5 is located on one side of the lower casing 1, and the fixed column 4 is far away from the column. One end of the cap 5 is fixedly connected with a block 6, and the side of the block 6 close to the fixed column 4 is fixedly connected with two springs 7, the springs 7 are respectively located at the top and bottom of the fixed column 4, and the spring 7 is far away from the end of the block 6 Both are fixed on the inner wall of one side of the card slot 2, the size of the lower case 1 and the upper case 9 are the same, and the opposite sides of the lower case 1 and the upper case 9 are provided with power supply installation grooves, and the protrusions 8 and the card slot 2 are located on both sides of the corresponding power supply installation slot, the number of locking devices is four, the bottom of the card slot 2 is divided into a straight bottom and a special-shaped bottom, and the card block 6 is placed on the flat bottom, and The bottom of the projection 8 is adapted to the shaped bottom, the sum of the lengths of the fixing column 4 and the block 6 is adapted to the length of the slot 2, and the bottom of the lower case 1 and the top of the upper case 9 are provided with cooling holes.
